Wall element for use in a prefabricated wall and prefabricated wall with a

such wall element

The innovation relates to a wall element according to the generic term “protection claim” and to a prefabricated wall according to the generic term 14.

Up to now it has not been possible, at least not with a reasonable amount of effort and result, to integrate windows, doors or fixed panels etc. or their external frames (panel or frame) into the walls directly during the manufacture of walls for prefabricated houses.

The aim of the innovation is to show a wall element which can be used as a structural unit pre-assembled with at least the frame or frame of a window, a door and/or a fixed panel in the manufacture of prefabricated walls for prefabricated houses. To solve this problem, a wall element is designed in accordance with claim 1 and a prefabricated wall in accordance with claim 14.

The innovation is based on the realisation that only the supporting frame, to which at least the frame for the window, door or fixed panel is held and whose thickness (distance between outer surface and inner surface) is equal to or approximately equal to the raw dimension of the wall thickness of the prefabricated wall, enables the integration of a window, door and/or fixed panel into a prefabricated wall directly during its manufacture in a particularly simple manner and in particular without changing the existing production equipment.

If, for example, the prefabricated wall consists of wall blocks that are arranged on an assembly or vibrating table to form the prefabricated wall and connected to one another using mortar, the wall element is also placed on this table and the prefabricated wall can then be formed around the wall element using the wall blocks.

The U-profile, which is open to the outside and formed by the parts of the supporting frame, enables a secure connection between the supporting frame and the adjacent parts of the prefabricated wall. The upper and lower profile rails, which are connected to the supporting frame, protrude beyond the supporting frame at both ends and are embedded in adjacent parts of the prefabricated wall, also make it possible for the wall element to extend over the entire height of the prefabricated wall and yet the prefabricated wall produced in this way can still be transported safely.

Further developments of the innovation are the subject of the subclaims. The innovation is explained in more detail below using the figures for an exemplary embodiment. They show:

Fig. 1 shows a simplified representation and a front view of a wall element according to the innovation;

Fig. 2 is a section along the line I -1 of Figure 1; Fig. 3 is a section along the line II - II of Figure 1 in a finished

Brick wall built-in wall element;
Fig. 4 shows a section along the line III - IM of Figure 1; Fig. 5 shows a section similar to the line I -1 in enlarged detail in

lower part of the wall element of Figure 1; Fig. 6 a section along the line IV - IV of Figure 5; Fig. 7 in an enlarged detail a section through a leg of the

surrounding frame of the wall element of Figure 1; Fig. 8 in detail the connection of a ceiling, preferably a prefabricated ceiling, to the top of the wall element.

The wall element generally designated 1 in the figures is also particularly suitable for use in walls for prefabricated brick houses. The wall element 1, which in the embodiment shown is shown with a single-leaf window 2 and a parapet 3 provided under this window, has a height

·

H which is equal to or approximately equal to the shell room height, i.e. when assembled, this wall element 1 extends from a building shell 4 or from a leveling layer 5 applied there (e.g. mortar tape) to the underside of the building shell or floor 6. When installed, the wall element 1 is part of a prefabricated wall 7, which in the embodiment shown is made from wall or bricks 8 which are connected to one another using reinforcing iron 9 and mortar to form the prefabricated wall 7. The production takes place in such a way that the wall stones 8 are placed with their side 8' forming the outside of the prefabricated wall 7 on a horizontal vibrating table, which is indicated in Figure 3 by the line 10 there. During assembly of the prefabricated wall 7, the wall element 1 is placed with its outer surface 1' on the vibrating table 10 at the location where the window 2 is to be provided in the prefabricated wall 7 and is then integrated into the prefabricated wall 7 in the manner described in more detail below. This production or vibrating table is.

The wall element 1 consists essentially of an outer frame 11, which has, among other things, two vertical frame elements 12, which reach to the underside of the wall element 1 and are connected to one another there by a horizontal frame element 13. The frame elements 12 and 13 are each made of a waterproof panel material, for example waterproof wood material, and have a U-shaped cross-section that is open towards the outside, namely the frame elements 12 with two parallel, spaced-apart legs 12', which lie with their surface sides parallel to the plane of the wall element 1 and thus also parallel to the plane of the outside 1' and inside 1" of this wall element, and a plate-shaped yoke section 12" connecting the legs 12', which lies with its surface sides in a plane perpendicular to the plane of the wall element 1. Flat, plate-shaped reinforcement blocks 14 are provided at predetermined intervals between the two legs 12', which are also connected to the yoke section 12" and lie with their edge remote from the yoke section 12" flush with the free edges of the legs 12'. In the area of the yoke section 12', the reinforcement blocks 14 are each provided with a

Recess 14'. The blocks 14 also serve to handle the wall element 1 using lever tools.

The lower frame element 13 consists of two leg sections 13' and a yoke section 13" connecting these leg sections, wherein the leg section 13' provided on the outer side 1' of the wall element is made, for example, from a plate-shaped plastic material.

In the embodiment shown, the leg 13' is part of a shell or plate 16 which forms the outer raw wall of the parapet 3. This wall is offset from the inner surface 1" of the wall element 1 towards the outside of this wall element in order to form a niche.

On the outside of the wall element 1, a shell or plate 16 adjoins the yoke section 13", which forms the raw outside of the parapet 3 and is level with the outside surface T of the wall element with its outer surface. Both plates 15 and 16 extend to a plate-shaped crosspiece 17, the surface sides of which lie in horizontal planes when the wall element is installed, which extends between the two frame elements 12 and is connected to them and which forms the lower boundary of the opening for the window 2 in the wall element 1 with its upper side. A vapor barrier 18 is applied to the inside of the plate 15 facing the plate 16. The space between the two plates 15 and 16 is also filled with an insulating material 19.

At the top, the frame elements 12 are connected to one another by an H-profile 20. The H-profile 20, which is also part of the frame 11, consists of the two parallel wall sections or plates 21, which extend over the entire width B of the wall element 1, as well as a further web-like wall section 22 connecting the wall sections 21, which also extends over the entire width B of the wall element 1 and with its

Surface sides lie in planes perpendicular to the plane of the wall element 1. On both sides of the wall section 22, the H-profile 20 forms an upper and a lower space, of which the lower space is used as a roller shutter box 23, while the upper space forms a U-profile that is open at the top, the legs of which are formed by part of the wall sections 21 and the yoke section of which is formed by the wall section 22. The space below the wall section 22 and used as a roller shutter box 23 is closed at both ends by a cover 24, which lies with its surface sides in planes perpendicular to the plane of the wall element 1 and with its outside flush with the free edge of the legs 12' of the respective frame element 12. Each cover 24 has an extension 24' with which it extends into the space between the legs 12' of the adjacent frame element 12 and is connected to these legs. Each cover 24 is provided with a bearing for the roller shutter shaft 25 housed in the roller shutter box 23. The inside of the roller shutter box 23 is equipped with the usual insulation or thermal insulation 26, which is shaped as an insulating body so that the roller shutter box interior 27 required for winding up the roller shutter armor remains. The wall sections 21 and 22 as well as the covers 24 are also made of panel material, e.g. wood.

The outer frame or sash frame 28 of the window 12 is fastened in the opening formed between the frame elements 12, the upper H-profile 20 and the cross element 7, whereby this sash frame 28 and also the sash frame, which is tiltable and pivotable on the sash frame and has the insulating glazing 29, are each formed from a multi-chamber plastic profile. In the upper, horizontal area, the sash frame is connected to the roller shutter box 23 via a connecting profile 31 and in the lower horizontal area to the cross piece 17 via a connecting profile 32 and insulation 33. The connecting profile 32 is used in a known manner to fasten the outer window panel 34 and to connect the inner window sill 35.

I · i

The stock frame 28 is essentially only held at the yoke sections 12" of the frame elements 12, with thermal insulation 34 being provided between the vertical sections of the stock frame 28 and the respective yoke section 12".

Two vertical guide rails 37 for the roller shutter curtain (not shown) are provided on the outside of the window 12 and immediately adjacent to the vertical sections of the frame 28. These guide rails 37, which are also made of plastic, for example, are designed so that their outer surface 37' is flush with the plane of the outside 1' of the wall element 1 and thus also flush with the plane of the outside 8' of the raw finished wall 7.

As indicated in Figure 1 with broken lines and shown in detail in Figure 7, several openings 38 are provided on the legs 12' on the inside of the wall element 1, namely for a roller shutter belt box, for mounting boxes for electrical switches, buttons, sockets, etc., whereby these elements (roller shutter belt box, mounting boxes) each extend into the space between the legs 12' with a part of their construction depth after assembly. On the outside of this leg 12' facing away from the interior between the legs 12', a grid-like plaster carrier 39 is then provided which covers the openings 38, so that after the wall element 1 has been installed in the prefabricated wall 7, the corresponding area of the legs 12' is plastered and the openings 38 which are not required are closed. The two plaster supports 39 are each clamped under plaster strips 40, which are attached to the outer side of the relevant leg 12' forming the inner surface of the wall element 1, namely along the vertical corner there with the yoke element 12". The reveal enclosing the opening of the window 2 on the inner side of the wall element 1 is formed by cover plates 41 forming the surface of this reveal, for example made of plasterboard or another suitable material, whereby these cover plates 41 are, among other things, attached to the outer surface of the yoke section 12" of each frame part

12 are held in place, e.g. by gluing. This design makes it possible to remove the window 2 or its frame 28 if necessary, e.g. for repair purposes or when replacing it, without major plastering work being necessary.

42 designates a reinforcing rail which extends on the underside of the wall element 1 in the middle over the entire width B of the wall element 1 and protrudes on both sides over the legs 12' of the vertical frame elements 12. The reinforcing rail 42, which extends horizontally and parallel to the plane of the wall element when the wall element 1 is installed, is formed in the embodiment shown from a T-profile made of steel and is arranged so that the center web of this profile points upwards. In the area of the vertical frame elements 12, the reinforcing rail 42 is held on the yoke section 12" and on an additional block 42 provided between the legs 12', approximately in the middle between the two legs 12'. A slot is made in the block 43 and in the respective yoke section 12" for the center web of the T-profile. The reinforcement rail 42 also serves to additionally integrate the wall element 1 in the lower area in the prefabricated wall 7 and for this purpose is provided with holes 42' in the T-leg on both sides of the central web, for example, into which the reinforcing iron 9 of the prefabricated wall 7 engage. In the figures, the reinforcement rail 42 is shown recessed. This rail 42 can also protrude downwards with its T-leg, so that the rail then also forms a lower impact or scratch protection.

The space between the legs 12' serves to accommodate pipes, cables, in particular empty pipes for electrical cables, with which the wall element 1 is pre-assembled. These cables or pipes laid in the space between the legs 12' are then guided through recesses 15 and are thereby fixed until the space between the legs 12' is filled. Since after the installation of the prefabricated wall 7 provided with the wall element 1, the underside of the wall element 1 is below the level 44 of the building floor, the lower space formed by the frame element 13 between the legs 13' is also used for

A19928DOC : ;:.. *::::: ·

It is used for feeding cables, pipes, etc. into the parapet 3, namely for those pipes, lines, etc. which are laid under the floor, as indicated in Figure 5 with the curved pipe 45.

As already explained above, the wall element 1 is integrated into the prefabricated wall 7 by placing it with its outer surface on the table 10 and then the prefabricated wall 7 is constructed from the wall blocks 8 around the wall element 1. The U-profiles formed by the frame elements 12 are used to integrate the wall element 1 into the prefabricated wall 7, i.e. the wall blocks 8 are arranged in such a way that they adjoin the free edge of the legs 12' with a certain joint, whereby the distance between the outer surfaces of the legs 12' of each frame element 12 is equal to the dimension of the wall blocks 8 in the same axial direction, so that the wall blocks 8 and the outer surfaces of the legs 12' each lie in the same plane. The reinforcing irons 9 arranged between the wall blocks 8 each extend into the space formed between the legs 12'. The respective space formed between the legs 12' is completely filled with a suitable mortar 48 (e.g. insulating mortar) via the openings 38 and the cables, pipes, etc. already pre-assembled in these spaces are also embedded in the process, with the mortar 48 then reaching as far as the adjacent wall blocks 8 and the wall element 1 thereby being completely embedded in the prefabricated wall 7. The parts of the prefabricated wall 7 formed on both sides by the wall element 1 are additionally connected to one another by the reinforcement rail 42. A similar connection is made via the steel profiles 46 in the upper area of the wall element 1.

As shown in particular in Figure 8, two U-profiles 46 made of steel are arranged in the space between the wall sections 21 above the wall section 22, parallel to one another and in an axial direction parallel to the plane of the wall element 1 in such a way that these U-profiles point upwards with their open side, rest with the yoke section of their U-profile on the top of the wall section 22 and are connected to this wall section in a suitable manner, for example by screwing. The two steel profiles 46 form, as shown below

Still to be described are, among other things, the lintel of the prefabricated wall 7 constructed with the wall element 1 and protrude laterally over the wall element 1 at both ends.

As described above, the guide rails 34 lie with their outer surface 37' flush with the outer surface 1' of the wall element, so that a laying or sealing tape 47 can be applied to these vertically running outer surfaces 37', but also to the upper and lower horizontal surfaces running along the window opening and flush with the outside Γ, before the wall element 1 is placed on the table 10, so that the window opening and the frame 28 pre-assembled in this opening are then protected with the guide rails 37 against the ingress of mortar, etc. when the prefabricated wall 7 is manufactured.

During the manufacture of the prefabricated wall 7 or later (e.g. on site), the space formed above the wall section 22 between the wall sections 21 is then filled with a suitable mortar.

Figure 8 shows the connection of the wall element 1 integrated into the prefabricated wall 7 to a ceiling. The space between the wall sections 21 above the wall section 22 is, as already described, filled with a suitable mortar 48, which together with the steel rails 46 forms the lintel. The ceiling 6 is then erected above this, using facing stones 49 arranged on the outer surface of the building and a prefabricated ceiling 50 or a ceiling formed from ceiling stones, etc.

During the manufacture of the prefabricated wall 7 or only on the construction site, a full thermal insulation 51 is applied to the outside of the prefabricated wall 7 as well as to the outer surface of the wall element 1, which then also partially covers the guide rails 37 or the surfaces 37'. This is possible because both the surfaces 37' and the outer surface 1' of the wall element are flush with the outer surface of the prefabricated wall 7.

IN THE ··

On the inside of the wall element 1 and on the inner surface of the prefabricated wall, a plaster 52 is applied during manufacture or on the construction site, which then also bridges the transition between the wall element 1 and the prefabricated wall 7, wherein the plaster carrier 39 is also provided in the bridging area.

The invention has been described above using an exemplary embodiment. It is understood that numerous changes and modifications are possible without thereby departing from the inventive concept underlying the invention.
