Description
MOUNTING SYSTEM OF SEMTPREFABRICATED CrVTL
CONSTRUCTIONS.
Field of technique
The object of the present invention is a mounting system of semiprefabricated civil constructions, characterised by having wall, floor, and ceiling panels that are constituted of prefabricated modular elements which, once positioned at the building site, have the function of the moulding for the filling of foundations, pillars and beams on site.
Background of the invention
For many years buildings have been constructed either completely in reinforced concrete and brickwork, directly at the building site, or prefabricated prestressed or metal reinforced concrete, with the creation of all the structural elements at the factory and with the successive assembly at the building site using the traditional fixing methods.
Therefore, within this context, to whoever intends to proceed to construct a civil or an industrial building, two different solutions present themselves: either proceed to construct directly at the building site, or prepare to buy a prefabricated structure.
Without lingering overlong on the constructions of reinforced concrete, characterised by a, by now, consolidated level of technique,
It is worth analysing some of the assembly systems for prefabricated buildings present on today's market.
They generally consist of prefabricated elements, constructed in the factory on the basis of predefined project specifics, and are later assembled at the building site using traditional fixing methods (mortises, bolts, etc.).
The prefabricated panels are generally constructed of prestressed reinforced concrete and/or vibrated, or made of steel; they are constructed at the factory, transported to the building site, and assembled by fixing them to the supporting structures that were previously assembled or built on the site.
3 000212
As confirmation of the above, there exist numerous examples of patents that claim new methods of assembly for completely prefabricated buildings: in fact, in the patent No. PCT/ES97/00062, a self-supporting prefabricated panel for buildings is described, which must be assembled on prefabricated walls, specifically constructed, and which can constitute one of the elements of a modular structure for the total construction of a building.
In the patent No. PCT/SI97/Q0019 too, a system for the construction of buildings is described, characterised by the fact that it is three times lighter than a traditional system and extremely versatile in the various uses that the single elements of the system may have.
Other patents, such as No. PCT/AU96/00279 and No. PCT/US93/01945, describe new modular systems of prefabricated constructions, these too, characterised by the fact of being able to offer characteristics of lightness and versatility during their assembly.
In the light of the above mentioned facts, it appears evident that, aside from the chosen type of building, the traditional building methods foresee first, all the preparation, or rather the assembly of the supporting structures, either in normal reinforced concrete or in prestressed concrete, or in steel, and only later the preparation, or rather the assembly of the floors.
Only once these operations have been carried out, are the walls and partitions in brick or prefabricated panels raised.
The principal scope of the invention that we are describing is that of being able to join, in one single solution, prefabricated elements that constitute floors, the external panels and partitions, to elements built traditionally; the whole in such a way that the same walls and floors constitute the moulding for the later concrete filling of the beams and the pillars of the structure.
The principal characteristic of the invention is the construction of a system for the assembly of semi-prefabricated buildings, constituted of foundation beams, walls and floors, for which, in the factory are prepared:
- the moulds for the foundation beams with walling in reinforced concrete and vibrated according to the specifics of the project;
- the external walls and the partitions constituted of prernixed plaster, insulating material, internal boarding, electro soldered wire mesh, concrete, fashioned on vibrating benches; said external walls and beams present holes at their lower parts for the passage of pipes for installations, a trapezoidal groove in the lower part, a hollow in the upper part formed by the two edges of the wall, openings for doors, external fixtures and niches;
- the floor and ceiling panels, constituted of prernixed plaster on the lower side, insulating material, electro soldered wire mesh, concrete, supporting structure, trellis, hollows for positioning the metal reinforcements; while at the building site;
- the moulds for the foundation beams are set out according to the project designs and, after having laid the reinforcing rods, their concrete filling takes place, and onto the said foundation beams a trapezoidal shaped part is fixed;
- the external walls and the partitions are laid out, with the groove present on the lower part coupled to the part present on the beam beneath;
- the floor and ceiling panels are laid out between the edges of the walls and the partitions;
- in the hollows between the walls and the floors, and in the floor and ceiling panels, the metal reinforcements are laid out according to the project specifications;
in said hollows the concrete fillings for completion are carried out, according to the class of resistance requested by the project, by the traditional system of filling the horizontal structures (beams) and vertical structures (pillars) contemporarily. It is evident, therefore, that such an invention allows for the perfect integration "within the system" of all the elements necessary for the
construction of buildings in a completely innovative way from the point of view of the method of construction of the same, associating the undeniable advantages of the prefabrication of the elements at the factory with the flexibility of the traditional constructions that guarantee the "freedom of shape".
Said system also has a series of advantages tied to:
- the time for the construction of the work is lowered by one third, with respect to traditional buildings;
- The possibility of having the external finishing of the sides effected at the factory, with a consequent saving on the hire of scaffoldings;
- The possibility of prearranging the installations directly at the factory;
- A consequent containment of the costs of construction and assembly. Another characteristic is the fact that the hollow in the upper part of the wall is formed by the two edges of the same wall having the same height.
A further characteristic is the fact that the hollow in the upper part of the wall is formed by the two edges of the same wall having different heights.
The system allows, therefore, the construction of buildings according to the following phases:
THE CONSTRUCTIONOF THEFOUNDATIONS
As can be evinced from figure 1, mouldings are prepared at the factory (15), with walls of concrete reinforced and vibrated according to the specifics of the structural project.
Taken to the building site, the metal reinforcements are laid out and the concrete filling of the foundation is carried out, leaving the reference rods in the pillars.
THE CONSTRUCTION OF THE EXTERNAL WALLS AND PARTITIONS
The walls of the buildings to be built are prefabricated at the factory. As can be evinced from figure 1, they are constructed in the form of modular panels, in various forms and dimensions, constituted of various materials (1,2,3 and 8), and fashioned on vibrating benches; this allows the guarantee of the
highest degree of cohesion between them, aside from making them complete with finishings on both sides, with a quality of construction evidently superior to that guaranteed by traditional methods.
Said factors allow us to obtain characteristics of fire resistance, levels of insulation, openings for doors and windows, niches, slots for the passage of the installations, hollows for lodging the metal reinforcements of the pillars and beams, everything according to specifications and the specifics of the project.
The walls are thus constructed in such a way that they can be transported to, and raised on, the building site, without the need for ulterior work in finishing.
What should be highlighted, at any rate, is the morphological conformation of each panel.
As can be evinced from figure 1, it is characterised, in the lower part, by the presence of a groove (the female groove) (19), trapezoidal in shape, which runs the entire length along the base of the panel, to be joined to a "part" (14), also trapezoidal in shape (the male part), which, prepared at the factory, is fixed to the underlying structure at the phase of concrete filling.
This system allows the perfect cohesion of the individual panels to the other elements of the construction, almost as a sort of guide for a bearing.
The wall, via the lower slots (13), can result ready for the passage of pipes for installations.
In the upper part, the walls present a hollow (17), which, according to case, can have the two edges of an equal height or of different heights, and everything according to the carpentry of the projected structure.
THE CONSTRUCTION OF THE FLOOR AND CEILING PANELS.
The floor and ceiling panels are also constructed in a prefabricated fashion at the factory(Figure 2).
They present themselves in the form of modular panels of various shapes and dimensions, panels constituted of various layers of diverse materials worked on vibrating benches; this allows us to guarantee the maximum level of cohesion between them, besides rendering them complete with finishings on the lower side
and ready for the laying of pavements on the upper side, with a quality of construction evidently superior to that guaranteed by traditional methods.
Said fact allows us to obtain characteristics of fire resistance, levels of insulation, openings for the passage of piping columns, hollows for placing the metal reinforcements of pillars and beams and girders according to the specifications and the specifics of the project.
The floor and ceiling panels thus constructed can therefore be transported and mounted at the building site without the need for ulterior finishing work.
From the morphological point of view, they present themselves in the form of parallelepipeds that meet at the edges of the hollows situated on the higher extremities of the walls, according to the carpentry of the project.
The modular panels of the floors contain, on their upper side, the hollows (16) for placing the metal reinforcements of beams of the thickness of the floor (joined to the pillars) and breaker beams, according to the predefined specifications of the project.
CONCRETE FILLINGS OF COMPLETION
As previously mentioned, once the modular panels of walls, floors, and ceilings are assembled, the metal reinforcements (18) are inserted as per project, with steel of the foreseen resistance in pillars, supporting beams, beams of the thickness of the floor, and breaker beams, the concrete filling of the class of resistance is carried out in the traditional way by the filling in place of horizontal structures
(beams) and vertical structures (pillars).
