 Method of manufacturing a building

description

The invention relates to a method for the method of manufacturing a building.

In disaster areas, the provision of accommodation is often cumbersome due to poor infrastructure and accessibility. The construction of hospitals, accommodation and other facilities and their facilities is therefore often difficult. If buildings are to be erected in a short time and with a minimum of transport, by which people or equipment to be protected from weather, vermin and other environmental influences, usually tents or prefabricated buildings composed of prefabricated buildings are used.

Although tents are light and quick to set up, they are limited in scope

Weather protection, insulate bad, do not protect against vermin, have a short life and hardly allow any privacy. From finished parts

Although composite buildings offer better comfort and have a longer life; but due to the mostly bulky items they have a large transport volume and often a considerable transport weight. DE 10 2009 049 298 A1 discloses a method for the production of such finished parts, which are formed from a foamed polymer material.

Furthermore, there are a variety of ideas for the construction of shelters, but have not yet been implemented. Thus, DE 102 58 542 B4 discloses an emergency shelter which is integrated in a parachute. When the parachute is dropped, chambers of the parachute are filled with a self-hardening foam which hardens during the flight; the landing parachute then represents the finished building.

The object of the present invention is to provide robust buildings and, if necessary, furnishings to be used therein in a fast and cost-effective manner, even in hard-to-reach areas of use.

The object underlying the invention is achieved by a method according to claim 1. Advantageous embodiments will become apparent from the dependent claims and the description below.

The core of the invention is now in particular, a building by foaming the shell mold itself to produce on site. The shell mold has a low weight before foaming and can be packed flexibly. Therefore, the cover shape is ideal to transport. The foam material can initially be transported to the predefined location in arbitrarily large tank facilities to save space. the foamed wall has a rather low specific weight compared to a wall of prefabricated panels; thus is also the stabilizing

Building material ideal to transport.

The building thus produced thus has a high degree of resistance to earthquake and weather, and can protect against heat, cold and noise in particular effectively. A lifetime of at least 5-10 years is possible; The building can offer about the comfort of a simple house. The disposal is possible without problems via a combustion plant or by chemical recycling.

In this case, the enveloping mold is preferably permanently fixed to the predefined location before foaming or during foaming, or it becomes the

Foamed wall fixed immediately after curing at the predefined location. In particular, during curing, the foaming material can enter into a permanent bond with the substrate at the predefined location.

Preferably, a bottom plate is created with a horizontal top surface on an uneven surface of the predefined location. The

Foam material compensates for unevenness of the substrate; on the top can be made by a shuttering the horizontal flat surface. Thus, such buildings can be easily produced even on mild to moderate slopes or on rocky ground.

The flexible shell mold, including any separate single shell molds from which a larger overall envelope shape can be formed, is preferably prefabricated transported to the predefined location and is foamed there. Since the sheath form is only foam on site, errors in the field work are largely avoided.

Preferably, the shell mold has a flexible outer shell and a flexible inner shell, wherein between the outer shell and the inner shell, a receiving space for the foaming material is formed. The outer shell provides in particular a

weather-facing outer surface of the building forms and is formed in particular of a weatherproof, water-repellent and / or UV-resistant material. In the The choice of material must take into account the location and intended use, in particular with regard to the expected service life and the expected loads. At high mechanical loads fiber-reinforced materials can be used. The inner shell provides in particular an inner surface of a room of the building. In this respect, the inner shell may have a haptic pleasant surface, for example made of textile material.

Between the outer shell and the inner shell distance limiting means are arranged, which are adapted to locally define a maximum wall thickness of the wall. By the distance limiting means is therefore the degree of

Foaming localized, so that excessive wall thicknesses are avoided; This can be done analogous to the embodiments of inflatable castles or inflatable tents. By means of the distance limiting means, the enveloping form can also be impressed on shapes, for example curves and corners.

Preferably, a shell mold is formed by a plurality of single shell molds, wherein a second of the individual shell molds before their foaming on a

Locking system is connected to a first of the individual wrappers. The

Connection of the two single wrappers can be done while the second single wrapper is not filled with foam; the first single wrapper can, but need not, be already filled with foam. The ability to combine single wrap forms into a total envelope, there are many ways to create a variety of different buildings from a limited selection of Einzelhüllformen in an individual way. The shape can even be influenced on site by selecting the individual wrappers. In particular, the size of the building can thus be adapted locally to the conditions.

Preferably, a first closure system for connecting the envelope shape of a first wall with the envelope shape of a second wall has different

Closure elements as a second closure system for connecting the envelope of the second wall with the envelope of a third wall. In particular, these three mentioned different walls are different types of walls, in particular floor plate, side wall and roof. By using different closure elements, such as zippers of different sizes, only matching shell shapes can be interconnected; a wrong assembly on site can be avoided.

As a closure system, in particular a zipper or Velcro is used. If the closure system in particular before foaming initially still solvable, the exact shape of the shell mold can be changed until the final foaming or curing.

Alternatively, an adhesive method may be used to join the single wrappers.

Preferably, a closed zipper is formed by two side parts which are engaged with each other. Upon engagement, an end piece is passed over one end of the closed zipper, the end piece engaging around at least one side panel end of the closed zipper. The tail can thus accidentally open the zipper

To prevent what is guaranteed by a starting piece in a commercially available zipper (for example on a jacket). As already mentioned, such initial pieces can not be used in some cases in the present application.

In particular, the subsequent attachment of the tail is useful when the tail engages exactly one side of the end of the closed zipper. In particular, this is advantageous if the corresponding side part ends of the two side parts are offset in the sliding direction to each other. What is meant by this will be apparent from Fig. 20a.

Preferably, the zipper includes a slider, with the help of the

Zipper from an open state to a closed state, can be converted, wherein the zipper comprises a locking means which secures the slide in an end position, insbesobdere closed zipper, against accidental release from this end position.

Preferably, the flexible shell mold is at least partially disposed around at least one solid structural member and the solid structural member is at least partially enclosed by the foaming material. This can be increased in a simple way, the stability of the building. The solid Strutkturelement can become an integral part of the foamed wall.

Preferably, the solid structural element is initially exposed, then the structural element is at least partially introduced at least partially through an opening of the shell mold in the shell mold and then the opening in the shell mold is closed, in particular by connecting two single shell molds. This can be done in the aforementioned way. Preferably, a first amount of foaming material is first filled in the shell mold in a lower area, then the first amount hardens at least partially. Subsequently, a second amount of foaming material is poured into the shell mold on the first amount of the foaming material. This procedure allows a uniform construction of the wall over its entire height. This avoids that not yet cured material is set too much pressure during curing by overlying material.

By the method described above, it is also possible to form walls that are part of movable or permanently installed furnishings. So furnishings such as furniture and sanitary facilities can be formed by foaming a corresponding envelope shape. In this case, a corresponding enveloping shape can be connected to a different enveloping shape of building walls as described before it is foamed via a closure system.

To protect mechanically heavily loaded, areas of walls, these are reinforced by reinforcing elements, such as fittings, such as strips, plates, or particularly solid shell materials.

The invention further relates to a method for producing and disposing of a

Building, comprising producing a building as described above, further crushing the walls and then supplying the crushed walls of a combustion or recycling process. Also, the disposal process is quite simple and can be done on local facilities.

The invention will be explained in more detail below with reference to the figures; herein shows:

Figure 1 shows schematically the structure of a simple building 10, which is produced by the inventive method. FIG. 1 a shows a cross section through the completed building 10. The building has walls 3 in the Substantially formed from foamed polymeric material. These walls are a bottom plate 3 ', a plurality of side walls 3 "and a roof 3"'. The walls comprise an enveloping mold 1, which in each case represents an outer skin of the walls 3. This envelope 1 is formed by film-like material, which depending on

Environment parameter is selected. On the inside, that is, the side facing an interior of the building, the envelope 1 is formed by an inner shell 11, which is preferably a textile fabric, which is similar to the feel of a wallpaper.

On the outside, so the outer environment of the building side facing the envelope 1 is formed by an outer shell 12, preferably on the

Weather conditions of the predefined location. In sunny areas, the outer shell 12 is preferably formed from a film with a correspondingly high UV resistance; in colder areas, the outer shell 12 becomes a

waterproof and cold-resistant (frost-resistant foil) film. Between the inner shell 11 and the outer shell 12 distance limiting means 13 are provided in the form of ribbons, threads or ropes, which define a maximum distance between the inner shell 11 and the outer shell 12. When foaming the enveloping mold 1, which will be explained in more detail below, the distance limiting means 13 prevent the outer shell 12 and the inner shell 11 from moving too far apart. So that we determined by the distance limiting means 13 locally the wall thickness of the wall 3.

Figure 1 b shows the circled in Figure 1 a section of the wall of the building enlarged. It can be seen that between the outer shell 12 and the inner shell a foamed with polymer foam 2 area is formed. After curing, for the most part the foam, in particular together with the wrapping material, provides the stability for the respective wall 3.

To stabilize the foamed bottom plate 3 ', it is covered with one or more soil stabilizing plates 4, in particular made of wood or plastic; In particular, the material of the soil stabilization plate 4 has a higher hardness than the foamed foam material 2. The bottom plate 3 'and / or the

Soil stabilization plate 4 is fixed by tie rods 5 firmly in the ground 6 of the site. A window or door opening 7 is usually incorporated in the prefabrication in the shell molds, but can also be produced by subsequent sawing from the cured foam material.

The basic structure of the walls 3 is also shown in FIG. The

Outer shell 12 and the inner shell 11 are made by solid and fixed threads or ropes 13 'fixed as a distance limiting means or glued, welded or sewn tabs or nets 13 "as a distance limiting means in their distance to after foaming with polymer foam 2 a predetermined

Wall thickness D to reach. A variable length of the distance limiting means between the two outer sheaths also allows a specific variability of the wall thickness. The wall thickness D can be a few cm (for furniture, for example) to over 50 cm (for strong walls or roofs).

FIG. 3 illustrates the function of the distance limiting means using the example of a reinforced corner of a wall. The shape of the corner and thus a course of the

Distance between the outer shell 12 to the inner shell 11 is made by different lengths

Distance limiting means 13 targeted.

The polymer foam is injected into the gap via inlet openings 9, in particular inlet valves, inserted into the envelope at specific intervals. The polymer foam spreads through the expansion and bonded to the material of the shell mold. The degassing case by diffusion through the shell or through inserted in the shell, not shown degassing valves.

FIG. 4 shows a building 10, which is produced on the basis of several separate single shell molds 1 ', 1 ", 1"'. The shell mold 1 'for the bottom plate 3', the shell molds 1 "for the side walls 3" and the shell mold 1 "'for the roof 1"' are connected together before filling the foam material at interfaces 14 on site. Thus arises from a variety of individual wrappers a total envelope form, the

can then be filled with foam. The interfaces 14 allow a simple connection of separate envelope shapes with each other in a wide variety of combinations. As interfaces 14 come in here solvable, in particular

line-shaped closure systems 14 for use, in particular the

Zipper or Velcro. By means of such closure systems 14, the individual enveloping forms can be quickly connected to one another and also released again (in the event of incorrect assembly). If the shell mold is subsequently filled with the foam and the foam hardens, the arrangement is preserved despite the detachable

Locking system their lasting stability.

Preferably, only such closure systems are used, which

have complementary configured to each other elements. A zipper has, for example, two side parts with matching staples, which are thus provided complementary to each other; By the targeted use of closure systems with mutually complementary elements can thus be achieved that the envelopes for individual walls can only be connected correctly with each other. The closure system 14 between the roof and the side wall thus has different elements than the closure system between the roof and the bottom plate. An incorrect assembly, for example, a compound of the shell mold 1 "'for the roof 3"' with the shell mold 1 'for the bottom plate 3 ", is thus excluded and can in

Disaster save valuable time.

Figure 5 shows in detail, such as the example of the envelope 1 'for the bottom plate 3' with the shell mold 1 "for the side wall 3" and the shell mold 1 "for the side wall 3" with the shell mold 1 "'for the roof 3' on different , circulating

Zippers, adhesive or Velcro fastener tapes 14 ', 14 "are connected to each other in one possible embodiment, only after the connection of the individual envelope shapes with each other foaming of a common interior, which is formed by a plurality of individual wrappers.

FIG. 6 shows the modular connection of individual building parts 15 to a larger building, e.g. a school or a hospital. After foaming of a building part 15 ', the envelope shape of the bottom 3' of the first building part 15 'by means of a zipper (or a Velcro or adhesive connection) 14' with the not yet foamed envelope 1 'of the bottom of the next second building part 15 "is connected. After foaming of this second building part 15 'any intermediate spaces 16 between the building parts 15 are sealed with tabs, for example with an adhesive tape 17, then the spaces 16 are also foamed with polymer foam (the figure 6 cuts the walls of the two buildings at the point of a passage 7 between the parts of the building.) Accordingly, at the junction of the roofs 3 "'of the two building parts 15 is moved.

The buildings 10 thus produced are comparatively light and are on

Secured underground, which is shown with reference to FIG 7. For this purpose, the buildings are anchored in the ground 6 with tie rods 5, here as hinged anchors 5 'or dowels 5 " evenly on the surface of the comparatively soft bottom plate 3 '.

In principle, the bottom plate 3 'can also be filled with ballast material 19, which is filled in in particular during foaming in the shell mold. As a ballast material is fine-grained material with a grain size of less than 2mm, for example, sand. The stability is increased here. Figure 8 shows a development of Figure 7. The fixations on tie rods 5 in the substrate 6 also allow to make the surface of the bottom plate 3 'during foaming so that a flat bottom surface is formed, even if the substrate 6 is not flat. For this purpose, the tie rods 5 are adjusted in such a way that formwork panels 21 fastened thereto lie in a common horizontal plane. To the

Tie rods are then fastened to the auszuschäumenden soil shuttering plates 21 by means of cross struts 20; the formwork panels 21 hold the surface of the bottom plate 3 'until it is horizontal and level. The cross struts 20 and the shuttering panels 21 are then dismantled and reused in the manufacture of the next building. The tie rods are shortened accordingly by removing intermediate pieces or with a cut-off grinder.

FIG. 9a illustrates how windows or doors 7 are inserted into the wall 3 with the aid of zips 22 and sewn-in, welded-in or glued-in tabs 23. The tab with the zipper is attached to the Hüllform 1. The windows 7 are formed of a sheet of transparent material and may be provided with a screen (e.g., secured by a Velcro tape).

It can also dimensionally stable windows 7, in particular glass or

Plastic discs are used in the wall, as shown with reference to Figure 9a. A simple hinge can be formed by one or more rods 24, which are simply inserted into the wall 3 of foam and to which the disc is attached.

On the basis of the other figures will be explained how heavily loaded areas of the building are specifically strengthened.

In Fig. 10, thin sheets (e.g., plastic or HDF) are adhered as soil stabilizing plates 4 for distributing the pressure load on the foamed bottom plate 3 '. To these soil stabilizing plates 4, a flooring 25, e.g. a rubber, plastic or laminate flooring, applied.

Highly loaded carrier areas, in particular on the roof 3 "'(FIG. 11), require high-strength enveloping molds 1"', which are in particular fiber-reinforced, for example by kevlar or similar fibers 26, and / or are provided with force-distributing elements, in this case a fitting 35. Floor corners can, for example, be glued-on, welded on or sewn-on tissue made of high-strength fiber or metal fabrics reinforced or secured against animal feeding. In an embodiment of the invention, not shown, the bottom plate on such a large wall thickness that a buoyancy of the building is achieved. By chains or ropes, the building can be attached to tie rods or other fixed fixed objects and / or the building can be secured by guides against floating away. This design provides survival space for humans and animals in flood plains. The building sinks back to the surface after draining the water.

A simplified embodiment without a bottom plate, in which the side walls 3 "are anchored in the ground, is shown in FIG. 12. Such an embodiment makes it possible to construct simple garages and material stores

Execution as foam-filled round arch, with tie rods 5, front and rear wall 3 "and roll-up door 27.

With the help of used before foaming moldings made of plastic, ceramic, wood or metal, the production of permanently installed furnishings is conceivable, examples of which are sanitary facilities such as showers, toilets,

Sink. FIG. 14 shows this using the example of a washstand 28. In this case, a wall 3 "" is produced by foaming, as already described. On the wall 3 "" a sink molding 29 is glued; a drain pipe 30 is integrated before the foaming in the shell mold 1 and is characterized by the

Foaming automatically laid in the wall 3 "". Also, the shell mold for the sink can be connected via a described closure system with the shell mold for the bottom plate.

Figure 15 shows an embodiment of a water basin 31, for example a

Bathtub, a therapy pool or (drinking) water storage. The

Water resistance is ensured by a glued-in sealing layer 32, in particular a

Rubber layer or plastic film, reached.

Figure 16 shows a table 33 as another example of a foamed

Furnishing. Such furnishing articles, which require a high degree of form precision for their use, are foamed with the additional use of a casing 34, which fixes the article in the critical dimensions until it hardens. The envelope 1 for the table is held by the example made of wood, cardboard or plastic casing 34 in the form. After foaming, the shuttering 34 can be removed and the shuttering can be reused for the next table. Such a formwork is also used in the foaming for other wall areas, where a special Dimensional accuracy is required, eg for window and door openings.

FIG. 17 shows, by way of example, further furnishing articles which can be produced in this way, for example a table with additional ones

Stabilization struts (Figure 17a), a chair (Figure 17b), a chair (Figure 17c), a shelf (Figure 17d) and a bed (Figure 17e) with a recess for a mattress.

FIG. 18 shows a plan view of a section of an enveloping mold 1 formed from a plurality of single-shell molds V-1. The individual Einzelhüllformen are each by

Zippers 22 connected together. In the following, with reference to FIGS. 18-22, the zippers will be described in more detail, which connects a first single-shell mold V with a second and a third single-shell mold 1 ", 1" '.

A basically known zipper comprises two side parts 41, each with side part ends 51 (see FIG. 19), and a slider 42. The slider 42 surrounds the side parts 41 and is displaced along the side parts 41 in the sliding direction S. During the shifting, depending on the direction, the staples of the zipper, which are not explained here, are engaged or disengaged from each other. A zipper, as it is e.g. from a garment, at the side-part ends 51 comprises an end piece which engages around both side parts and ensures that the side-part ends 51 and thus the side parts 41 do not detach from each other during use.

The side parts 41 ', 42 ", 43"' lie in the region of a T-connection point 43, as shown in detail in FIG. 20a, offset from one another in such a way that the mutually corresponding side-part ends 51, 51 are not aligned with one another or offset from one another. In order nevertheless to connect the side parts 41 to one another permanently, end pieces 43, 44, 45 are provided, which surround the side parts 41 and, after closing the respective zipper, are placed on the respective ends of the closed zipper. A "closed

Zipper "designates a section of two mutually complementary side parts 41, which are engaged with each other, as shown for example in Figure 19b and Figure 20, right part, Such end pieces can as I-end pieces 44, T-end pieces 43 or X-end pieces 45 may be formed.

FIGS. 19a and 19b show, by way of example, the longitudinal section through an end piece 44, here an I-end piece 44. The end piece has a receiving space 46 for receiving the end pieces

Side parts 41 on. The tail has an enlarged receiving area 47 and a reduced receiving area 48 adjacent thereto. The enlarged one Receiving area 47 can receive end portions 52 of side panels when the associated zipper is opened at that location (Figure 19a). The reduced receiving area 47 can accommodate end portions 52 of side panels when the associated zipper is closed at that location (Figure 19b). This feature is applicable to all types of end pieces.

In principle, one end piece can have a plurality of separate receiving spaces 46 ', 46 "for side parts. <br/> <br/> In each receiving space, side parts of different zippers can be accommodated.

Figure 20a shows a section through the T-end piece 43 of Figure 18, in plan view. Figures 20b and 20c show the T-end in side view, viewed from the right in the sliding direction S. The first side part 41 'thereby passes through the first receiving space 46' of the end piece 43 therethrough; the side parts 41 "and 41" terminate in the T-end piece 43, respectively. There are two enlarged receiving areas 47 and a

to recognize intermediate reduced receiving area 48 in the first receiving space 46.

In addition, ends here in the T-end in the second receiving space 46 "another closed zipper, which with their respective side panel ends

(indicated by the reference numeral 52 ^* ) is shown in Figure 20a. This additional closed zipper is aligned at an angle to the aforementioned zipper.

FIG. 20 shows an example of the zipper in the receiving space 46 ', in which the mutually corresponding side part ends 51 are not aligned with each other (the side part ends of the side part 41' are outside the image area here). When zipper in the receiving space 46 ", the two corresponding side part ends 52 ^* are aligned with each other.

Basically, depending on the design of the side parts of the closed

Zipper provide a sufficiently high density. Here, a comparatively high viscosity of the foam and rapid hardenability has a positive effect; a certain amount of leakage is acceptable. In the area of a side panel end, where the closed zipper ends naturally, the tightness may not be sufficient without further action. The end pieces can contribute here to an improvement in the tightness.

To fix the relative position of an end piece on the side part, for example a bolt may be provided, for example in the form of a pin inserted 51, which secures the position of the end piece relative to the side part (Figure 18, 20b, 20c).

In a development, the slider 42 can be connected to an end piece 43, 44, 45 via a securing mechanism, which prevents unintentional removal of the slider 42 from the tail. This will be explained with reference to the figures 21 a and 21 b, for example, the tail 43. Figure 21 a shows a longitudinal section parallel to the sliding direction S, Figure 21 b shows a partially sectioned plan view. The slider 42 has a barb 49, which has a locking surface 50 of the

End piece 44 engages behind. Likewise, the barb on the tail 44 and and the backup surface on the slider 42 may be attached. This safety principle is also suitable for other types of end pieces.

An inner surface of the receiving portion of the tail may be provided with a material 61 which increases the friction (Figure 22). This also applies to all types of end pieces. For example, rubbery materials can be used, which conform to the side part 41 and counteract slipping out of the side part 41 from the end pieces. It is particularly advantageous if the friction-increasing material 61 supports the insertion of the side part, but prevents removal. For this purpose, fibers can be used, which are arranged so that they face away from an opening, as shown for example in FIG. Particularly suitable are plastic or fabric surfaces with a "fur character" and a strong "dash line". Fibers, e.g. Hair or wires can act like a barb.

FIG. 23 shows a possibility of how solid structural elements 53, explained here by way of example with reference to a wooden post, are integrated into the production of the building. FIG. 23a shows two initially free-standing wooden posts 53 and a first single-shell form 1 '. The wooden post 53 is introduced through an opening 55 in the Einzelhüllform V. By at least one zipper 22, e.g. two zippers or a circumferential zipper, a second single wrap 1 "is connected to the first single wrap form V. The two

Single shell molds 1 ', 1 "now delimit here a receiving space in which the wooden post 53 is received, the opening 55 is thus closed

Receiving space is now filled to form a wall 3 (Figure 23c). The wooden post 53 is enclosed by the foamed material and can increase the stability of the wall 3 produced. FIG. 24 shows the almost identical procedure, for example for a

Corner. The second single-shell mold 1 "may be formed by a narrow strip which closes the opening 55 of the first single-shell mold 1 '. This narrow strip 1" may also be formed integrally with the first single-shell mold 1'.

FIG. 25 shows different side parts as walls. It can closed side panels (Figure 25a), side panels with a window frame (Figure 25b) or

Side parts with a door frame (Figure 25c) are formed.

The steps for producing a building using structural elements 53 will be explained with reference to FIGS. 26 to 29. First, a floor is produced by the use of bottom single shell molds 1 ', 1 "and solid structural elements 53 (Figure 26), as described with reference to Figure 23. The wall produced there now corresponds to a bottom part as a wall otherwise prepared soil can be used.

At the bottom, upwardly projecting structural elements 53, e.g. Wooden posts or metal bars arranged (Figure 27). Now side wall 3 can be prepared as described with reference to Figure 23.

Figure 28 shows that the structural elements for the side walls a

Roof construction is applied. The walls of the roof can be prepared according to Figure 23.

FIG. 29 shows the completed building with roof parts and side parts. The

The order in which the side parts and the roof parts are mounted is arbitrary. In order to protect the walls edge strips 54 are preferably attached to edges of the walls.

FIG. 30 shows a modification of the method steps according to FIG

Structural element 53 is now a window or door frame. The second envelope shape is fastened, for example adhesively bonded, to the structural element 53 in the form of a flap 1 ". The struture element 53 is partially inserted into the first through the opening 55

Single wrapper introduced. Anschließd closes the opening 55 by means of zipper 22 and the subsequent foaming.

31 shows a possibility for fastening a second structural part 53 "to a first structural part 53 ', which is already surrounded and in particular foamed by an enveloping mold 1. In this case, the second structural part 53' is applied to the enveloping mold 1 and Subsequently, the two structural parts 53 ', 53 "are screwed together with a screw 56. The screw 56 penetrates the enveloping mold 1 and in particular the foamed material 2.

The method during the filling of an enveloping mold 1 will be explained with reference to FIG. The foaming material is stored in a reservoir 58. By means of a pump 59, the material is pumped into lines 60. The lines 60 are connected to inlet valves 57 on the enveloping mold 1. First, a first amount of foaming material is conveyed into the shell mold 1 via a lower inlet valve. The filled material of the first amount then cures. Subsequently, a second amount of foaming material is conveyed through an overlying inlet valve in the same envelope shape. The filled material of the second amount then cures. This process is repeated until the enveloping mold 1 is completely filled.
