Description

[Technical Field]

[0001] The present invention relates to building walls. [Background technology]

[0002] International Publication WO 2017 / 081212 A1 discloses a method for producing a multi-wall building by first rolling out a flexible envelope foam into a predetermined position, then filling the flexible envelope foam with a foam material, and subsequently curing the foam material to form stable walls.

[0003] German Patent Publication DE 19950139 A1 discloses a method for closing the gaps between beams of a roof truss. The beams provide sufficient mechanical stability. In this case, the strips are attached to the beams with clamps and then filled with foam. The grid spacing between the spacers is relatively large, exceeding approximately 10 cm, which leads to relatively large deformations of the surface, but this is acceptable for the roof structure. The intermediate spaces delimited and filled by the sheets extend continuously, for example, from the purlin to the ridgepole (Sp. 1, Z. 11ff) and typically have a length of well over 2 meters. A similar structure is known from German Patent Publication DE 3502323 A1. Summary of the Invention

[0004] It is an object to provide an improved building wall.

[0005] The object underlying the present invention is solved by a building wall, a building and a method as set out in the main claims, while embodiments are the subject of the subclaims and description.

[0006] The present invention includes a building wall, which may be a floor wall, a roof wall, or a side wall of a building. The wall has a base frame including a plurality of braces. The braces are preferably made of wood. The base frame defines spaces between the braces. The spaces are filled with a foam filling material.

[0007] In one embodiment, the intermediate space is delimited by an envelope foam, in particular a woven foam, in particular adjacent to the brace, in particular the envelope foam delimiting the intermediate space transversely to the wall surface, while the brace delimits the intermediate space in a direction parallel to the wall surface.

[0008] In particular, a plurality of spaces are formed between each other, each separated by a horizontal brace.

[0009] Each intermediate space can be provided with its own envelope form, so that several arranged envelope forms are provided above and below one wall.

[0010] Alternatively, a common first shell (outer or inner shell) can be provided in some intermediate spaces on at least one side. If there is a common first shell on one side, the envelope form is placed around the brace starting from the side with the common first shell and attached to it from both sides. For this purpose, the brace can be guided through a passage between two adjacent second shells (outer or inner shells).

[0011] In another embodiment, both the outer and inner shells are designed to define multiple intermediate spaces, where individual braces are inserted through insertion channels in a pre-assembled envelope form, which can have continuous shells on both sides.

[0012] The division of a wall into multiple interspaces, one above the other, favors the formation of uniformly filled interspaces. The height of a single interspace is therefore limited by the horizontal braces. As a result, a new interspace begins at each horizontal brace. For uniformly filled interspaces, a low total filling height is preferred. In particular, the height of the interspaces in the side walls is a maximum of 1.5 m, especially a maximum of 70 cm.

[0013] In one embodiment, the envelope form includes an outer shell defining an intermediate space outside the wall and an inner shell defining an intermediate space inside the wall.

[0014] In one embodiment, the outer shell and the inner shell are connected to each other by at least one connecting thread, in particular by a plurality of connecting threads, which in particular bridge the intermediate space. In one embodiment, the envelope foam is prefabricated with the outer shell, the inner shell, and the connecting threads.

[0015] In one embodiment, the envelope foam is attached to braces of the base frame, with the outer shell fastened to the outer side of the braces of the base frame and / or the inner shell fastened to the inner side of the braces of the base frame, and the fastening is particularly performed in such a way that the braces at least partially limit the space to be filled with the filling material in the direction of the wall surface.

[0016] In one embodiment, two adjacent intermediate spaces in the wall are each bounded by two separate outer shells and / or each bounded by two separate inner shells. In this case, adjacent intermediate spaces in the wall are each bounded by two separate envelope forms. In particular, when using pre-manufactured envelope forms with connecting threads, it is not possible to simply bound several intermediate spaces by a common envelope, since the envelope must pass through the intermediate space in each case. Possibilities for resolving this conflict are described within the scope of this application.

[0017] In one embodiment, a common brace is disposed between two adjacent intermediate spaces, and the two separate outer and / or inner shells are attached to the common brace.

[0018] In one embodiment, the wall, particularly the base frame of the wall, includes several interspaces. Each interspace is separated from the others by a common brace. Dividing the wall into sections creates multiple smaller interspaces, which are then individually filled. Tests have shown that a foam quality of the plastic foam that meets the high requirements for wall or roof elements in terms of strength, impermeability, and thermal conductivity can be achieved, especially when the size, especially the height, of each interspace to be filled is relatively small. Furthermore, the additional braces improve the stability and dimensional stability of the base frame, and therefore of the finished wall.

[0019] In one embodiment, the wall is a floor wall, which is placed on a particularly uneven ground. The intermediate space is at least indirectly delimited on the floor side by the ground. The foil can delimit the intermediate space below and can be placed on the floor in particular. The advantage is that no substantial preparation work on the ground is required. The foil can be applied to untreated ground, and irregularities are automatically leveled by the infill material. The foil prevents material interaction between the ground and the infill material.

[0020] In one embodiment, the intermediate space, particularly for the bottom wall, is filled in layers with several amounts of filler material. Filling in layers can improve the quality of the foamed material. In particular, the material has a uniform density distribution, which prevents the filler material from peeling off from the wall during hardening.

[0021] In one embodiment, the intermediate space is bounded at the top by a plank, which in particular includes a plurality of holes for introducing the filler material. The plank forms a defined closure of the intermediate space at the top, allowing the floor to be broad and flat at the top. In particular, the plank is considered a component of the mold, since it is already connected to the intermediate space when the filler material is filled. The holes in the plank are particularly useful for receiving the small amount of filler material required to completely fill the intermediate space.

[0022] The invention further relates to a building having a plurality of walls of the aforementioned type.

[0023] The present invention further comprises: providing a base frame; fastening the envelope form to a base frame; and filling the intermediate space with at least a quantity of filler material, which filler material is foamed after filling.

[0024] In one embodiment, a pre-fabricated envelope form is used, whereby the inner shell of the envelope form is joined to the outer shell of the envelope form by connecting threads before the envelope form is attached to the base frame, which allows for easy assembly of the envelope form on site, as only pre-fabricated elements need to be inserted and fastened.

[0025] In one embodiment, the envelope foam passes at least partially through the intermediate space. Further, the outer shell of the envelope foam is attached to the brace on the outside of the wall, and the inner shell of the envelope foam is attached to the brace on the inside of the wall. In this manner, the inner and outer shells, which are firmly attached by the connecting threads, can be attached to a prefabricated base frame.

[0026] The inner and / or outer shells can be fastened to the brace using a sealing layer (e.g., adhesive tape, elastic or paste-like sealing material) and clips hammered into the brace. This is a simple and stable method that does not require special tools.

[0027] In one embodiment, the outer shell and / or the inner shell are pressed against the brace with fastening fasteners. In particular, the outer shell or the inner shell is clamped between the fasteners and the brace, which allows a secure fastening and sealing. The fasteners are in particular arranged circumferentially around the intermediate space, whereby the fasteners can also be arranged with several individual fastener parts (the fasteners do not have to be individual fastener parts that are integral and closed all around).

[0028] In particular, the following basic conditions must be taken into account:

[0029] In particular, when foaming filler materials using foam plastics such as polyurethane, polystyrene, or PIR (polyisocyanurate), only a limited amount of foam material can be introduced into the interspace in the available time "in one shot." Therefore, each interspace is relatively small in size. If a large amount of filler material is inserted simultaneously, the reaction heat in the interspace can cause overheating, potentially damaging the frame, filler material, or other elements.

[0030] The walls preferably support the mechanical load-bearing capacity of the wall in addition to its thermal properties. Therefore, the base frame can be manufactured in a much more cost-effective manner. For mechanical strength, it is advantageous if the foam forms a direct material bond with the base frame. This is possible by applying high pressure during manufacturing.

[0031] Preferably, a predetermined pressure of the filling material is achieved in the intermediate space: for this purpose, a precisely calculated amount of filling material is filled into a defined intermediate volume and hardens into a foam of defined density.

[0032] High pressure is also advantageous for: · Avoid large voids in the filling material (to prevent thermal bridging and loss of mechanical strength). Avoid gaps / peeling between the base frame and the filling material (preventing thermal bridging, loss of mechanical strength, and leakage of air and water vapor). · Strengthens the foam due to compression that occurs during the foaming process.

[0033] The required pressure build-up and, in particular, the limitation of the amount of fill material introduced at one time, require an intermediate space of defined size, closed on all sides. Furthermore, overflow of foam into adjacent chambers during foaming must be avoided, as otherwise the pressure may not be set correctly and, if necessary, the fill material may flow into the adjacent intermediate space and foam there in an uncontrolled manner.

[0034] Intermediate spaces with large length or width dimensions (side lengths exceeding 1.5 m), especially when foamed with inappropriate pressure, tend to cause the hardened filler material to shrink and change the shape of the base frame (e.g., bow inward). Therefore, to keep the side lengths of the intermediate spaces small and limit bending, sealing and reinforcing braces, especially horizontal braces, should be inserted at regular intervals (e.g., approximately 0.5 to 1 m).

[0035] To optimally fill the intermediate spaces, the foam material has a particularly low viscosity, which remains low during or immediately after foaming, and which is necessary to completely seal the intermediate spaces.

[0036] Preferably, the inner and outer shells are joined to the base frame, in particular by means of double-sided adhesive tape or an elastic or pasty sealing material.

[0037] Preferably, the filling of the intermediate space takes place through an opening in the base frame or through a raised edge of the envelope foam, after which the opening is closed, for example by means of a plug, or the raised area is sealed, in particular by means of a clip, in particular during the foaming stage, in particular by means of a wooden or metal strip.

[0038] Preferably, vents (e.g., holes) are provided in the upper corners to allow air within the element to escape, which would otherwise not be able to completely fill the intermediate space in the upper region.

[0039] The advantages and embodiments mentioned with respect to the method and apparatus are also applicable to the apparatus and method. [Brief explanation of the drawings]

[Figure 3] Process steps for the manufacture of side walls or roof walls. [Figure 4] 1 is a base frame of a bottom wall according to the present invention. [Figure 5] 1 is a process step for the manufacture of the bottom wall. [Figure 6] 4 is a wall envelope form according to the invention in a further embodiment. [Figure 7] 4 is a wall envelope form according to the invention in a further embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0042] Figure 1 shows a plan view of a base frame 2 of a wall according to the invention. The base frame includes several braces 21, 22, which are aligned in different directions, specifically transverse to one another, to form the wall surface. If the wall is a side wall, the first brace 21 is oriented vertically and the second brace 22 is oriented horizontally. In the case of wall elements, the individual braces 22 can also be aligned at an angle to the horizontal, for example, to accommodate the roof slope in the case of a gable wall. In this case, the envelope form must be designed accordingly.

[0043] Between the braces 21, 22 an intermediate space 23 is formed, which is filled with a foam filling material during the manufacturing process of the wall.

[0044] FIG. 2a shows a detailed view of an envelope form 3. Such an envelope form 3 defines an intermediate space 23 transverse to the wall surface. The envelope form 3 includes an outer shell 31 that covers the intermediate space 23 on the outer side 11 of the wall and an inner shell 32 that covers the intermediate space 23 on the inner side 12 of the wall (FIGS. 2b and 2c). The outer shell 31 is connected to the inner shell 32 by a number of connecting threads 33. When the intermediate space 23 is filled with a filler material, the filler material generates internal pressure in the outer shell 31 and the inner shell 32. The connecting threads keep the outer shell 31 and the inner shell 32 at a predetermined distance from each other, preventing bulging. Additionally, the bending stiffness of the wall can be increased by pushing in the filler material and tensioning the connecting threads (similar to reinforced concrete).

[0045] Walls must be constructed so that the infill material provides a significant portion of their stability. Because the base frame is so small, the frame alone may not provide the required load-bearing capacity of the wall. Therefore, the frame can be constructed much more cheaply than a wall manufactured by classical carpentry using, for example, a wooden frame.

[0046] To provide the load-bearing capacity of the wall primarily through the filler material, the filler material must be introduced into the intermediate space during foaming so that a high pressure (overpressure) of at least 1.2 bar is generated in the intermediate space. In particular, the filler material, even in its hardened state, permanently generates a particularly significant overpressure of at least 1.2 bar in the outer and inner shells. To take advantage of this, further configurations are advantageous.

[0047] During filling, the amount of filler material is very important, as it has a decisive influence on the generation of a favorable minimum pressure during hardening. Therefore, it is advantageous for stability if the most accurate amount of filler material is filled into the intermediate space. The density of the filler material in the intermediate space is used as a target parameter that can vary depending on the application and material. For example, 50 kg / m 3A density of 1000 cubic meters (m3) is required to form a sturdy wall. From this, the exact amount of fill material to be filled into the interspace can be calculated, taking into account the volume of the interspace. The fill is then carried out with the exact amount of fill material. The optimum pressure for the fill material is then automatically set, specifically at least 1.2 bar during hardening.

[0048] The high number of connecting threads per unit area can be seen in Figure 2, which ensures that the finished wall surface has the most uniform shape possible and allows for high compressive strength of the envelope material. The preferred number of connecting threads per unit area is in particular at least 100, preferably at least 200, or 1000, or 2000 connecting threads per square meter. The connecting threads are in each case particularly evenly distributed over the length x and width y.

[0049] The distance between two adjacent connecting threads in the length direction x and width direction y is in particular at most 5 cm, in particular at most 2 cm. In particular, at least the individual connecting threads have a distance of at most 10 mm from one another.

[0050] The intermediate space is relatively small, which is the only way to achieve uniform high pressure, dimensional stability, and a sufficiently low reaction temperature within the packing material. The side lengths of the intermediate space, i.e., the length of the intermediate space 23 (x direction) and the width of the intermediate space 23 (y direction), are a maximum of 1.5 m, preferably a maximum of 1.2 m.

[0051] Such envelope forms 3 can be pre-manufactured. For assembly, the envelope forms 3 should be partially passed through the intermediate spaces 23 from one side. Thus, each envelope form is only used to delimit a single intermediate space 23.

[0052] Figure 3 shows the steps in the manufacture of a wall in cross section. On the outside of wall 11 and on the inside of wall 12, braces 21, 22 are each provided with double-sided adhesive tape 57 (Figure 3a). Using adhesive tape 57, outer shell 31 is attached to the outside of braces 21, 22 and inner shell 32 is attached to the inside of braces 21, 22 (Figures 3b and 3c). As an alternative to adhesive tape, other (especially elastic or pasty) adhesive and / or sealing media can also be used.

[0053] Now, a further envelope form 3b is attached to the brace to which the envelope form is already attached. If there is still enough adhesive tape remaining, another envelope form can be attached with this adhesive tape. Otherwise, a second double-sided adhesive tape 57b is attached to the first envelope form 3 in the brace area, thereby securing the further envelope form 3b to the brace. For permanent fastening, circumferential fasteners 58 are attached to the envelope form in the brace area and are specifically fastened to the brace separately, i.e., in addition to the adhesive tape. This can be done by a screw connection 59 to the brace (Figure 3d). This ensures permanent fastening of the envelope form to the brace, even if the adhesive strength decreases with age. Staples or nails can also be used as fasteners for the envelope form.

[0054] However, this overlapping arrangement of the envelope forms in the brace area is not necessary. Also, if there is sufficient space for this, the envelope forms can be attached adjacent to each other to a common brace. Two adjacent envelope forms can also be attached to the common brace using a shared adhesive tape or two separate adhesive tapes.

[0055] The space 3 is then filled with a foamable filling material 4 (Fig. 3e).

[0056] Figure 6 shows a variant of the envelope form 3 according to Figure 2a. The envelope form is designed to delimit several intermediate spaces. For example, the outer shell 31 is designed to be integrated for several intermediate spaces. Several separate inner shells 32 are formed to delimit only one intermediate space at a time. Therefore, passages 34 are provided between the individual inner shells, through which the braces 22, in particular the cross braces, can pass between the two inner shells and reach their destination between the connecting threads 33. The envelope form 3 as well as the base frame 2 can be pre-assembled to a large extent.

[0057] The inner and outer shells are then attached to the brace as previously described.

[0058] Figure 7 shows a further modification of the envelope form 3 according to Figure 2a. The envelope form is designed to separate several intermediate spaces. The outer shell 31 and the inner shell are therefore designed to be integrated with respect to several intermediate spaces. There are insertion channels 35 for braces (particularly cross braces 22), which can pass through the connecting threads. After passing through, the passed brace 22 can be connected to another brace 21 (particularly a vertical brace 21). In this embodiment, too, the envelope form 3 and the base frame 2 can be pre-assembled to a large extent. In the case of the base frame, the vertical braces 21 must then be attached to the horizontal braces 22.

[0059] The inner and outer covers are then attached to the brace as previously described.

[0060] Figure 4a shows a base frame 2 in one embodiment of the bottom wall. The base frame 2 has first and second braces 21, 22 aligned in different directions and forming an intermediate space 23 between them. The intermediate space 23 can be further substructured by an intermediate brace 24, as shown in Figure 4b.

[0061] Figure 4b shows a cross section of a plank 55 which covers the intermediate space 23 during the manufacturing process of the bottom wall. The plank 55 can also be used in the design according to figure 4a (without intermediate brace 24).

[0062] FIG. 5 shows a further step for manufacturing the bottom wall 1B on uneven ground 91.

[0063] A foil 52 is placed on the ground 91. Several ground anchors 51 are inserted into the ground (Fig. 5a). The ground anchors 51 are designed to apply tension to the ground 91. When the ground anchors 51 penetrate the foil 52, the foil 52 must be sealed with the ground anchors 51.

[0064] Such a ground anchor 51 may include a threaded rod that is fixed into the ground.

[0065] A grounding bracket 53 is attached to each tie rod 51 by a grounding fixture 54 (FIG. 5b). The grounding bracket may be an L-shaped bracket. The grounding fixture 54 may include, for example, a nut attached to a threaded rod. Each brace 21, 22 of the base frame 2 of FIG. 4 is attached to the grounding fixture 54.

[0066] Intermediate spaces 23 are now formed between the braces 21, 22, which are subsequently filled with a foam filling material. The excess foil can be cut off (FIG. 5c).

[0067] The filling process then begins (Figure 5d). First, a first amount of foamable filling material 41 is introduced into the intermediate space 23. This first amount is placed in the edge areas of the intermediate space 23, particularly in the corner areas of the braces 21, 22. The areas of the grounding fixtures and metal fittings are also surrounded by filling material. The initial filling is a small amount of filling material, which seals the individual intermediate spaces from each other and the underside of the frame against the foil. This small amount of filling material prevents the base frame from being lifted by the pressure of the foam. The first amount of filling material 41 is then allowed to harden for a few minutes.

[0068] A second amount of filler material is then introduced into the intermediate space 23 (Fig. 5e). In the area of ​​the intermediate space, the ground surface 91 is covered with a thin layer of filler material over the entire surface. The filler material also flows into the gaps between or under the braces that occurred during the pressureless hardening of the previous fill. This closes these gaps and ensures a good bond with the frame material. The intermediate space 23 is not completely filled. The second amount of filler material 42 is then allowed to harden for a few minutes.

[0069] The above process can now be repeated as many times as necessary until the filler material reaches approximately a predetermined average distance D (here, for example, 4 cm) from the upper edge O of the brace (FIG. 5f). For example, a third amount of filler material 43 is applied to the second amount of filler material 42 and then allowed to harden for several minutes. If any portions of the hardened filler material protrude above the brace, these portions can simply be cut off and placed within space 23, after which they are surrounded by the next amount of filler material.

[0070] Here, the upper part of the intermediate space 23 is covered with a thick plate 55. The thick plate 55 has holes 56, each about 10 mm in diameter, spaced at regular intervals of about 40 to 80 cm.

[0071] Now the final amount of filler material 44 is introduced through these holes 56 (Fig. 5h). This amount now foams and fills the intermediate space 23 completely, at least over most of the surface, up to the top plank 55 (Fig. 5i). It is important that the final amount of 44 added is not too much, as otherwise too much pressure from below on the plank 55 may occur, causing bulging. [Explanation of symbols]
