Description

A CONSTRUCTION MODULE, PARTICULARLY A WALL MODULE

OR A ROOF MODULE

The subject of the invention is a construction module, particularly a wall module or a roof module, to quickly mount buildings of street furniture, based on wooden modular systems, particularly recreational and utility buildings. Prefabricated construction segments enable standardisation, better quality of the modules in the workshop and flexibility in composing a construction structure.

There is disclosed in the Polish utility model description Ru 52492 a prefabricated wall element in the shape of a channel plate equipped with beams, made from structural concrete, in which reinforcing steel of a criss cross pattern is embedded. The beams are encased with structurally cooperating with them wooden strips blocking with an insulating layer of the self-extinguishing Styrofoam. Constructional beams have cut-outs with the reinforcement and notches and tongues.

There is known from the Polish utility model application Wu.96393 a wall panel, being an element filling walls in low wooden structures. It has a shape of a closed rectangular prism filled with a layer of thermal and sound insulation consisting of mineral wool and cork, separated from the external walls of this rectangular prism with an insulation layer from the material moisture impermeable.

There is known from the utility model description Ru 56097 a wall building unit in the form of a rectangular prism with two vertical cut-outs situated on the two side walls, built from the internal construction tightly embedded in a cast casing from the filler adjusted to transferring static loads. The internal construction is made of a prestressed insulating material in the form of a planar polygonal base with a situated in the middle rectangular opening and perpendicularly coming out from the base vertical ribs placed parallel to each other so as to eliminate heat bridges.

There is known from the utility model description Ru 62507 a wall module containing seeding boards, creating the surface of the wall and supported by profile support rails situated at different heights behind the wall. Every seeding board has on its back side at least two projections, situated at different heights, in order to link the board with the support rails, situated at different heights, and an adjustment screw to vertically set the board, adjoined to one projection acting as a support of the board, whereas the other projection is in sliding contact with the support rail .

A panel, particularly a wall panel, is known from the utility model application Wu.112439. The longer side edges of the panel have a shape of profiles: left and right, while the left profile of one panel after joining the right profile of the other panel make a characteristic flat profile. Moreover, the right profile in cross-section has an outline similar to a wavy line and the left profile in cross-section has the shape of the letter U, turned left through an angle of 90°, whose upper arm is shorter that the lower one. Additionally, a characteristic flat profile created as a result of joining left and right profiles is symmetrical.

A wall panel to construct bearing elements, consisting of layers, is known from the utility model description Wu.119452. It comprises two magnesium plates, joined by the filler, preferably Styrofoam. The panel has a wide application in the construction of detached and multi -dwelling units, municipal, social and industrial objects and public facilities.

There is disclosed in the Polish application P.298252 a prefabricated wall element to build it, of a very low heat penetration coefficient. The framing load-bearing wall has at least two frame prefabricated elements firmly attached separately, made of a wooden frame, if need be having internal reinforcements, to which from one side vapour barrier material and from the other side planks are fixed, situated perpendicularly to the side walls of the frame and adjoining each other. The space between the vapour barrier material and the planks is filled with the heat- and/or sound- insulating material. To the external side of the load-bearing wall a layer of Styrofoam with the facade material is fixed according to the invention. Frame connection of the prefabricated elements is a tongue fixed to one side of the frame and the corresponding feather fixed to its other side and draw bolts. There is disclosed in the utility model application Wu.311092 a wall element, suitable for being used as a modular element of external walls, internal walls, floors, ceiling and roof constructions, which consists of building units in the form of bars, made from the concrete or geopolymer foam material and having identical sections in the shape of isosceles triangles, which are in contact with their side surfaces, particularly are glued to each other in such a way that the bases of these triangles create planar front and back surfaces. In the bases there are recesses, of a U-section, running along the mentioned building units, whose filling can regulate the construction physical properties of such a modular element. The filling can be used to place heat-insulating materials, usually non-organic foam material, and also to place materials influencing static properties, e.g. concrete in the reinforced form. In order to change the static properties, inside the wall element it is possible to change the share of the building units made on the one hand from the foam material and the concrete on the other. As a result, we get a wall element, consisting of only two basic components, of high flexibility of application, which has many possibilities in the field of matching the construction static properties, in particular heat-insulating.

An external wall element, particularly a panel in the area of the fa ade of a building is disclosed in the patent description PL 179140. The external wall element has a transparent external heat-insulating layer between the glazed, external, absorbing the sun radiation wall coating and the internal wall coating neighbouring the external wall coating, while the internal wall coating consists a finishing layer, limiting the external wall element from the inside. Between the internal wall coating and the transparent heat-insulating layer of the external wall coating, there is an absorbing layer neighbouring the transparent heat-insulating layer. On the finishing layer of the internal wall coating, form the external side of the wall coating, there is a heat-insulating layer. The external wall coating consists of single glass panes, covered with an internal heat-insulating layer with a low emission coefficient. Optionally, the panes are covered with a protective sunscreen layer. The external wall coating has panes, from which at least one has at least one surface covered with the heat-insulating coating of the low emission coefficient. Optionally, the external wall coating consists of at least two panes which are situated close to each other. The panes are covered with protective sunscreen coatings. The interpane spaces of the external wall coating are filled with a noble gas and placed in the interpane space of the prismatic structure or perpendicular to the surface of the pane of the honeycomb structure. On the internal wall coating from the side of the transparent internal heat- insulating layer there is a heat accumulating layer neighbouring the absorbing layer. The heat accumulating layer has at least one mineral plate, ceramic plate or contains glass, natural or artificial stone in the form of concrete. The internal heat-insulating layer contains polyurethane foam, polyester foam, glass fibres or mineral fibres or is at least one filled with air space of the thickness of 10-50 mm. The internal finishing layer contains steel sheet, aluminium sheet or concrete. The transparent heat- insulating layer of the external wall coating is made of mineral wool, foam based on the acrylic resin, filled with air space of the thickness of 5 to 50 mm or consists of capillary plates from transparent plastic of the cellular structure perpendicular to the surface of the layer, in particular of the honeycomb structure. The value of the coefficient of the total energy transmittance of the external wall coating is so reduced that with the maximum expected intensity of the sun radiation on the absorbing layer, the temperatures which would lead to the material impurity cannot happen.

There is known from the patent description PL176931 an external wall element for buildings, in which in order to use the solar energy between the internal wall coating and permeable for the sun radiation external wall coating, there is placed, bordering with the latter, also permeable for the sun radiation, an external heat-insulating layer, separated with the bordering surface, absorbing the sun radiation from the external heat-insulating layer from the belonging to the internal wall coating, internal heat- insulating layer, while at least the internal wall coating is equipped with the edgy, reaching at least to the bordering surface, and conducting heat in the direction of the internal side of the wall, frame elements, which can be parts of the frame, panel sheet and so on. The external heat-insulating layer and the frame elements are separated from each other with the help of, badly conducting heat, insulating elements which protect the internal heat-insulating layer at the side of the frame elements along the edge belt situated in the boarding area. The insulating elements have such heat conductivity parameters that the heat flow through the insulating elements and frame elements to the surface, separating the frame elements from the room, gives the same temperature as an appropriate surface of the internal wall coating has. The insulating elements surround the external heat-insulating layer along the edge on the whole circumference and the whole thickness and adhere on one side to the internal heat- insulating layer and on the other side they adhere as well to the internal wall coating. Directed towards the external heat-insulating layer, the surface of the heat-insulating elements goes aslant in relation to the plane of the external wall coating so that the limited by the insulating elements surface of the external heat-insulating layer is on the internal surface of the external wall coating bigger than on the surface neighbouring the internal heat-insulating layer. The external wall coating and the frame elements of the internal wall coating are connected with the help of spacer elements, which adhere to the external wall coating on the side of the external heat- insulating layer and the insulating elements are placed between the external heat- insulating layer and the spacer elements, protecting the spacer elements.

A multilayer wall element is disclosed in the Polish application P.322184. The longitudinal edges of the external paving on the one side of the element are curled inwards in the shape in the cross-section of the letters U turned upside down, with voids in the middle, making two elastic connecting tongues. The third tongue is created by the upper narrowed part of the element's core. On the opposite side of the element, the longitudinal edges of the external pavings protrude outside the longitudinal edge of the core and are doubly curled inwards to the element, once in the shape of the letter U in the cross-section and the second time in the shape of turned upside down U letters with voids in the middle, creating in this way two elastic recesses and three elastic grooves.

A frame wall building unit is presented in the Polish application P.339528. It consists of two parallel side plates with situated in their internal sides longitudinal beams, to which in a perpendicular way vertical , carrier plates are fixed, linked with each other in the upper and lower part with the help of longitudinal stiffening strips, creating in total the chest-shaped carrying skeleton. On the upper and lower surface of the vertical carrying plates, on both sides of the longitudinal stiffening strips insertion holes are created at a given depth, into which in the upper part the connecting dowel pins are hammered of the dimensions and distance corresponding to the insertion holes from the lower surface.

An external wall panel and wall structure made from external wall panels is disclosed in the Polish application P.357176. The wall structure comprises a carrying frame and external wall panels, fixed to the frame and filled with heat insulation, while the external wall panels are placed one on the other in such a way that the lower belt of the top external wall panel directed downwards at least partially rests on the lower belt of the bottom external wall directed to the outside. The wall structure also contains external skin panels fixed to the external wall panels. Internal surface section and directed downwards upper collar and lower collar situated on the edges of the upper belt and lower belt also are also included as the ingredients of the panel made from the sheeting. Both in the upper belt and in the lower belt there are heat perforations and the external surface of the heat insulation is in the area of the surface which goes parallel to the internal surface section, through the upper collar and the lower collar protrudes from the surface to the distance of the air slit.

There is presented in the Polish application P.383659 a modular wall element, preferably containing gravelite, equipped with metal connectors, partly protruding outside, facilitating connecting with other elements, and equipped with the mounted door and/or windows and/or installation elements, particularly electric, characterised in that the plate I is firmly attached to the carrying construction of the wall together with situated between them, on the the one side of this carrying construction, spacer elements, and plate II is firmly attached to the carrying construction of the wall together with situated between them, on the other side spacer elements, and in the internal space of the construction partition there is a substance of good heat- insulating properties, preferably filling this space and joining permanently all the elements contained; the substance, in the form of a stiff foam, is a mixture of foam plastic and filler.

There is presented in the Polish application P.386470 a wall element manufactured from the material of heat-insulation, containing an external plate, internal plate and at least two intermediate posts situated between the external plate and the internal plate, in which the wall element is placed to be filled with the mortar mix, while the lower channel is created below the intermediate post ad between the external plate and the internal plate.

There is presented in the Polish application P.390356 a roof and wall air sun collector which uses metal coating of a roof or wall . The solar energy heats the metal sheet covered preferably with the absorber. Insulating foil resistant to temperature fixed with the help of the insulation tape to the sheet creates air channels, with which the heated air is transported to the heat receiver, where after giving away the heat comes back to the lower collecting collector channel.

There is disclosed in the Polish application P.392005 a wall coating, containing a set of panels, each of which is formed with a set of horizontal rows of building units element imitations, such as manually placed stones, separated with the imitations of the line of the masonry mordant. The panels have end areas with shaped hooks and side cut-outs, being the slits to enter the hooks, suited to mutual connection, as a result of relative, transverse moves of the side end areas during the installation, with the rows of building units imitations from one panel, led to the established, levelled out spatial relation in relation to the rows of building units and the adjacent panel. Lying deeper the side of the end area of each panel is moreover shaped with non- planar, corrugated surface, similarly to the line of the masonry mordant passing through the panel and the covering side of the end area of each of the panel is moreover shaped with the complementary, corrugated surface, to be fixed with a close suitability on the corrugated surface of the covered end surface. There is known from the Polish application P.394827 a construction of a building, particularly from prefabricated elements, which is characterised in that in the holes of the concrete plate sleeves are fixed and into them threaded steel flexible connectors coming through the holes are screwed into them in the ground beam, on which on both sides of the row of the steel flexible connectors wall beams are placed and on the steel flexible connectors spacer connectors are pulled and moved into the recesses in the wall beams. On the perpendicular point of contact of the wall beams corner connectors are put. Between the layers of the wall beams on the steel flexible connectors spacer strips are slid with the holes, pressing down the layers of the spacer connectors to the ground beam by screwed in coupling nuts on the steel flexible connectors. At the height of the next layer of wall beams subsequent steel flexible connectors are screwed in. The space between the wall beams is filled with the extrusion mixture, preferably polyurethane foam. At the height of the lower level of the structural ceiling on the steel flexible connectors with the holes girts are put and pressed down with nuts. The girts are the base for the multilayer prefabricated structural ceiling with an external edge insulated with the extrusion mixture filling the space inside the next layer of the external wall beams. Over them there is a roof, preferably made in a prefabricated way.

There is known from the Polish patent description PL180038 a construction module to build planar constructions, particularly walls, consisting of two parallel wall parts in the form of plates, whose turned to each other external surfaces make a part of the construction surface of the wall, and the module core created from many separately made and joined parts. The module core is placed between both wall parts and is firmly connected with them The module core has a going in the longitudinal direction of the construction module at least one part in the shape of strips or a layer of wood, entered between the wall parts of another wall construction module to create with them a pinning connection taking over the strengths acting in the transverse direction. Moreover, the module core has elements creating with the module core of another construction module a pinning connection taking over the strengths acting in the longitudinal direction. Part of the module core creating the pinning connection acting in the transverse direction, is basically placed on the whole lengths of the construction module. The module core is created by fixed to the construction module to the wall elements and situated in the longitudinal direction of the construction module two strips and numerous ribs joining placed vertically within the distances in the longitudinal direction and joining both pairs of the strips. One of the pairs of strips, preferably the top pair of the strips assigned to both wall elements, protrudes in the vertical direction from the wall elements constituting part of the core taking over the transverse strengths created in the transverse direction while seating another construction module, while the other pair of strips is moved in relation to the wall elements to the inside of the construction module. The pinning connection working in the longitudinal direction is created preferably by pivots and transverse crevasses assigned to the frontal sides of the connecting ribs. The top frontal sides of the connecting ribs are placed in the same plane as the top surfaces of the pair of strips and the bottom frontal sides of the connecting ribs are placed in the same plane as the bottom surfaces of the bottom pairs of strips. The pivots are preferably placed on the bottom sides of the frontal connecting ribs and crevasses on the top sides of the frontal connecting ribs. The pivots and the opposite crevasses are placed in equal distance from both wall parts. The connecting ribs have two pivots placed in the equal distance from the wall parts and two opposite crevasses. One of these sides of the frontal connecting ribs has additionally a longitudinal groove and the second frontal part has a longitudinal tongue opposite to the longitudinal groove, while the plugs relatively crevasses, are placed in the middle in the transverse direction, between one of the wall parts and the longitudinal groove, relatively longitudinal tongue, and the width of the longitudinal groove and longitudinal tongue corresponds preferably to the thickness of the wall parts. The centres creating the pinning connection working in the longitudinal direction are assigned to the upper surfaces of the upper pair of strips and to the lower surfaces of the lower pair of strips. The connecting ribs divide the surface between the wall parts into many vertically empty through spaces, being in one line with suitable empty spaces of the seated construction module.

There is also known a modular connecting node of spatial construction structures consisting of elements of identical thickness and identical sizes of the cuts, in which the basic modular unit is a tetragonal carrier plate with made cuts in the axis of every arm into the depth not smaller that one fourth of the height of the side, connected separately by the cuts with the rectangular connection plate of the width equal its triple thickness and with the cuts placed in the longitudinal axis on two opposite arms.

There is also known from the Polish application number P.329326 a construction module to build planar wall constructions. This module has two parallel wall parts in the form of plates, whose external surfaces are the outer surface of the building wall. The module core made of the wood connects both wall parts and contains at least one part, going in the longitudinal direction of the module, which is destined so that while seating the next construction module it should go in the vertical direction between the wall parts of the next module and together with it create the pinning connection, taking over the strengths, working in the transverse direction. In this and similar solutions of construction modules, the vertical strengths are basically moved by suitably chosen with regard to their resistance plane wall parts being at the same time external but not of uniform structure surfaces of the built walls. Giving a different design to the walls requires using additional facing products.

There is presented in the patent description PL 195459 a construction module being an element of the wall frame; which has carrying posts joined with each other in series with spacer plates with edges put into the inside of the post, from which the utmost posts have to the lateral sides fixed coupled wings to join with the adjacent modules. The coupled wings have after being joined the length equalling the length between the adjacent carrying posts. From the frontal side the carrying posts have the known pivot joints for vertical connections with adjacent modules. Spacer plates are situated in the middle part along one, preferably vertical surface of the symmetry, or close to the external ones. The basic construction module according to the invention has a few, for example four, vertical carrying posts moving strengths, made preferably in the shape of a rectangular prism and situated in a series, from which the neighbouring opposite posts are connected rigidly with spacer plates with the edges put into the inside of the plates. Spacer plates in the shape of rectangles seated in the furrows of the posts set their vertical position in distances equal to each other. The utmost posts have fixed from the external side sides joined rectangular wings and with the edges put also to the inside of the posts. On the side utmost edges they have step-shaped furrows and to connect in an overlapping way with each other adjacent modules. On the opposite frontal sides the posts have cooperating with each other mortises and pivots. The pivots are fixed for example at the bottom of the posts or are separate elements in the kind of pins of a round section, put in the suitably matched mortises, made in both frontal parts of these posts. The module elements are made from wood, derived timber product for example chipboards or other building materials of similar parameters of resistance and are connected rigidly with the gluing technique and/or with the help of generally known mechanical joining means e.g. nails and screws of the next layer. Elements and modules made from them are covered with the water and fire resistant mediums. The modules can be from the lateral side put directly next to each other and seated on each other vertically from the frontal side. Symmetrical construction allows for a free longitudinal setting of the module without differentiating the external and internal built wall of the building. By seating the pivots in the mortises of 7 adjacent modules and connecting them in a series, the possibility of moving the modules both in the longitudinal and transverse directions is limited. Through additional catching of the modules with the ground beam and ceiling beam ensures creation of stable sets, being the frames of carrying walls and partitions of the erected building.

There are known building constructions erected from beams, most frequently from the coniferous trees, which after being cut because of the moisture contained in them require long seasoning. The walls of the buildings are erected from the beams by putting beams one on the other and connecting them with each other with the pivoting technique and in the erection of the corner walls the beams with previously made at the end incisions, most frequently from one side to the half of their thickness, are fastened in a cross way behind them. Buildings of this kind are erected from the dry beams and that is why to accelerate the drying process it is known longitudinal wiping of the beams into narrower elements, which are then dried in industrial chambers and connected with each other with the gluing technique.

There is known from international application number W0997/39204 a construction module to build planar wall constructions. This module has two parallel wall elements in the form of planes, whose external surfaces are the outer surface of the erected wall. The module core made from wood joins both wall elements and contains at least one part, coming in the longitudinal direction of the module, which is destined so as to while putting another constructional module enter in the vertical direction between the wall elements of the next module and together with them create pinning joins, taking over the strengths working in the transverse direction.

In this and other known similar solutions of construction modules for example from the European description EP-0214088 and EP-0744507, vertical strengths are carried from the suitably chosen considering the resistance plate wall elements, being at the same time external surfaces of the erected walls. Giving a different design to the walls requires using additional facing products.

Construction module is also presented in the patent description PL206724. It consists of a carrying construction, being the carrying ribs placed in set with the stiffness of the construction distances from each other. To the carrying construction from one or two lateral sides, being the external or internal side of the construed wall is fixed a profiled towards the outside jacket, made from one or few shaped stones 3, situated longitudinally and at the same time transversely regarding the carrying ribs. The ribs have preferably the form of a prism, placed horizontally. Its height is simultaneously the thickness of the rib, which measured along the module is about a few centimetres. The support construction with ribs in the shape of cuboidal blocks can be strengthened e.g. by oblong connectors. On the opposite, frontal sides, the ribs can have, for additional increase of the stiffness and stability of the walls, cooperating with each other pivots and mortises for a layered vertical connection of adjacent modules. The pivots are fixed permanently or are separate elements of the block type with the round section, put in the suitably matched mortises in both frontal parts of the ribs. The pivot connections additionally make it possible to very carefully set the modules against each other while erecting the walls of the building object, which ensures the connection of the ribs on the whole adjoining frontal surfaces. The jacket is profiled on the outside in the form of the worked trunk and can have smooth or freely shaped surface. Shaped stones of average thickness basically not exceeding 2.5cm have at the bottom preferably flat surface and on the outside they are suitably profiled to the outline of the jacket which they create. The ribs are situated in relation to the jacket in such a way that their upper or lower frontal walls are situated approximately at the upper and lower height of the outline of the jacket or a little below or above this height.

The essence of the invention is that in the external coating, wooden or metal flat bars are preferably alternately connected with strips permeable to the sun radiation, under which a ceramic accumulation layer is fixed, with a metal net partly embedded in it and partly protruding in the ventilation slit; connected with the heat-insulating layer in the internal coating, while the ventilation duct connecting the ventilation slit with the channel is separated with a movable regulating closure for the airflow. The metal net is a net made of metal of a high thermal conductivity coefficient, preferably a copper alloy. The channel is placed in the frame, preferably the upper part of the module. The channel is additionally placed in the frame in the lower part of the module. The external coating has gaps, which preferably are placed under the strips. The gaps are separated with walls (26) permeable to the sun radiation. The field joint consists of at least one sleeve and a supported against a stressed spring screw bolt, which is blocked in the sleeve by a pullable pin and/or pressed down by a tumbler fixed to the frame. An advantageous feature of the solution according to the invention is a possibility of regulating the air flow of the air ventilating the space between the external coating and the internal coating of the module.

According to the invention, the construction module has an external coating 1_ made of flat bars 11, permeable to the sun radiation, connected longitudinally on the grooves with strips 11a, separated with the slit 3 from a multilayer internal coating 2 with an accumulation layer 21 linked with a heat-insulating layer 23 neighbouring a finishing layer 24, and a framing 4 connecting the internal 2 and external 1 coatings with mounting holes 50 in which field joints 5 are placed. In the external coating 1, wooden or metal flat bars 11 are preferably alternately connected with strips 11a permeable to the sun radiation. Under the external coating 1 a ceramic accumulation layer 21 is fixed, with a metal net 22 partly embedded in it and partly protruding in the ventilation slit 3_i connected with the heat-insulating layer 23 in the internal coating 2. The metal net 22, whose task is to absorb the thermal energy from and to the airflow, is a net made of metal of a high thermal conductivity coefficient, preferably a copper alloy. The metal net 22, by absorbing the thermal energy from the airflow carries it to the embedded part and transfers it to the ceramic accumulation layer 21. If the temperature of the airflow in the ventilation slit 3 is lower than the temperature in the ceramic accumulation layer 21 , the thermal energy is carried do the flowing airflow. The ventilation duct 30 connecting the ventilation slit 3 with the channel 6 is separated with a movable regulating closure 31 for the airflow. The channel 6 is placed in the frame 4, preferably the upper part of the module. The channel 6 is additionally placed in the frame 4 in the lower part of the module. Optionally, to allow more light inside, the external coating 2 has gaps 25, which preferably are placed under the strips Ha. The gaps 25 are separated with walls 26 permeable to the sun radiation. The field joint 5 consists of at least one sleeve 50 and a supported against a stressed spring 52 screw bolt, which is blocked in the sleeve 50 by a pullable pin 53 and/or pressed down by a tumbler 54 fixed to the frame 4.

The invention will be presented below in the examples of manufacturing a wall module and a roof module.

The construction wall module 71 has an external coating i made of flat bars , permeable to the sun radiation, connected longitudinally on the grooves with strips 11a. The external coating 1 is separated with the ventilation slit 3 from a multilayer internal coating 2 with an accumulation layer 21 linked with a heat-insulating layer 23 neighbouring a finishing layer 24. The internal coating 2 and the external coating 1 are connected with a framing 4 with mounting holes 50 in which field joints 5 are placed. In the external coating i, wooden or metal flat bars 11 are preferably alternately connected with strips 11a permeable to the sun radiation. Under the external coating 1 a ceramic accumulation layer 21 is fixed, with a metal net 22 partly embedded in it and partly protruding in the ventilation slit 3. The metal net 22, whose task is to absorb the thermal energy from and to the airflow, is a net made of metal of a high thermal conductivity coefficient, where a copper alloy is used. The metal net 22, by absorbing the thermal energy from the airflow carries it to the embedded part and transfers it to the ceramic accumulation layer 21. If the temperature of the airflow in the ventilation slit 3 is lower than the temperature in the ceramic accumulation layer 21, the thermal energy is carried do the flowing airflow. Due to using the airflow in the ventilating slit the temperature of the external and internal coatings are regulated. The surpluses of the thermal energy while heating the walls with mounted modules are carried to the unexposed to light part of the building or to the heat accumulator or to the ground, for the later use by the heat pump. The ventilation duct 30 connecting the ventilation slit 3 with the channel 6 is separated with a movable regulating closure 31 for the airflow. The channel 6 is placed in the frame 4 in the upper part of the module, which enables joining the channels of the neighbouring modules. Thus the channel 6 is additionally placed in the frame 4 in the lower part of the module. The modules in the beams of the wooden construction are mounted with the help of field joints placed in recesses of the frame 4. The field joint 5 consists of at least one sleeve 50 and a supported against a stressed spring 52_screw bolt 5Jj which is blocked in the sleeve pressed down 50 by a tumbler 54 fixed to the frame 4.

The roof module 70 has a construction identical with the wall module. It has an external coating i made of flat bars Π., permeable to the sun radiation, connected longitudinally on the grooves with strips 11a. The external coating 1 is separated with the ventilation slit 3 from a multilayer internal coating 2 containing an accumulation layer 21 linked with a heat-insulating layer 23 neighbouring a finishing layer 24. The internal coating 2 and the external coating 1 are connected with a framing 4 with mounting holes 50 in which field joints 5 are placed. In the external coating 1, wooden or metal flat bars 11 are preferably alternately connected with strips 11a permeable to the sun radiation. To allow more light in the interior of the room, the internal coating 2 has gaps 25, which are placed under the strips 11a. The gaps 25 are separated with walls 26 letting the sun radiation inside the room. Under the external coating I a ceramic accumulation layer 21 is fixed, with a copper metal net 22 partly embedded in it and partly protruding in the ventilation slit 3. Due to using the airflow in the ventilating slit the temperature of the external and internal coatings are regulated. The surpluses of the thermal energy obtained while heating the walls with mounted modules are carried to the unexposed to light part of the building or to the heat accumulator or to the ground, for the later use by the heat pump. The ventilation duct 30 connecting the ventilation slit 3 with the channel 6 is separated with a movable regulating closure 31 for the airflow. The channel 6 is placed in the frame 4 in the upper part of the module, which enables joining the channels of the neighbouring modules. Because of that, the channel 6 is also placed in the frame 4 in the lower part of the module. The modules in the beams of the wooden construction are mounted with the help of field joints placed in the recesses of the frame 4. The field joint 5 consists of at least one sleeve 50 and a supported against a stressed spring 52 screw bolt 51 , which is blocked in the sleeve 50 by a pullable pin 53 fixed to the frame 4. After pulling out the pin 53, the screw bolt 51 is moved out of the sleeve 50 in the frame and is moved into the sleeve in the construction beam 8.

To mount the module in the opening between the construction beams of the construction object, a construction module is placed into the appropriate place of the construction and the field joints 51 are released on the perimeter of the frame 4 of the module. The modules prefabricated in the workshop are of standard dimensions and are fit to the designed house construction.
