Description

The invention relates to a device for connecting building components according to the preamble of claim 1 and a corresponding kit.

Structural elements, particularly walls or parts of walls, must be connected to one another, especially if their upper sides cannot be held horizontally by other structural elements. This applies in particular if there is no upper wall connection, which is the case in attics, for example, and especially if there is a wooden roof structure.

BREMEN MUNICH OSNABRÜCK GERMANY NUREMBERG ALCANTE HoUerallee 73 Widenraayerstrasse 48 Rolandsmauer 9 Business Park/ Keplerstrasse 10-12 Karolinenstrasse 26 P. Expl. de Espana 3,5° Dcha. D-28209 Bremen D-80538 Munich D-49074 Osnabruck D-07549 Gera D-90402 Nuremberg E-03002 Alicante/Spain

In particular, when the walls are made of storey-high, prefabricated wall elements, it is necessary to fix their tops in the horizontal direction by connecting the tops of the individual wall elements to each other if vertical edges of adjacent wall elements facing each other are not connected to each other or are only insufficiently connected to each other.

It is known to connect building parts, especially walls or even prefabricated wall elements, to one another on their upper sides in a horizontal direction using so-called ring anchors. These ring anchors are usually designed as reinforced concrete structures. This requires formwork, into which appropriate reinforcement made of structural steel is first inserted and then filled with concrete. The production of such ring anchors is very labor-intensive and therefore expensive. In particular, the formwork and the subsequent concreting are time- and labor-intensive. In addition, known ring anchors made of reinforced concrete delay the construction time because the concrete must first harden before it can be loaded.

Based on this, the invention is based on the object of creating a device and a kit with which an immediately effective connection of building parts, in particular walls, wall elements or the like, can be created in a short time and with simple means.

To solve this problem, the device according to the invention has the features of claim 1. Accordingly, the holding means assigned to the tops of the building parts to be connected are made of a flat material, in particular a web-shaped flat material, such as sheet metal strips, and separate connecting means, whereby the connecting means fix the flat material to the tops of the building parts. The flat material, together with the connecting means used to fix it to the top of the building parts, forms a type of ring anchor. In contrast to known ring anchors made of reinforced concrete, there is no need for formwork, pouring concrete and, above all, hardening of the concrete. The

Flat material can be pulled off a roll as a semi-finished product, for example, and simply placed on the tops of the structural parts to be connected. All that is then required is to fix the flat material to the tops of the structural parts using suitable connecting means. After the flat material has been fixed to the structural parts, these are connected to one another in a horizontal direction by the device according to the invention in the manner of a ring anchor. This connection can also be loaded immediately.

In the simplest case, the flat material only needs to extend over adjacent areas between neighboring structural parts to be connected. Preferably, the (sheet-like) flat material is laid continuously over the tops of the structural parts to be connected. This creates large areas for fixing the flat material to the tops of the structural parts, which allows the use of a variety of connecting means and the creation of large connecting surfaces, and ensures a reliable connection of the tops of the structural parts using the flat material.

Preferably, the (sheet-like) flat material is arranged flat on the top sides of the structural parts. The device according to the invention therefore requires virtually no additional space and thus creates a space-saving ring anchor.

According to a preferred embodiment of the device according to the invention, the flat material is designed to correspond to the top of the building parts. In particular, the sheet-like flat material extends over the entire width of the top of the walls, wall elements or the like. This results in practically complete coverage of the top of the building parts by the sheet-like flat material, whereby the entire top of the building parts to be connected can be used to connect the flat material to the building parts.

It is conceivable to assign strip-shaped sections of the flat material, in particular sheet metal sections, to adjacent surface areas on both sides of a connection point between adjacent structural parts. The remaining areas of the top sides of the walls are then not covered. This partial covering of the walls is usually sufficient to reliably connect the structural parts.

Where appropriate, in the areas of connections between

&iacgr;&ogr; adjacent structural parts, different sections of the web-shaped flat material are arranged so as to overlap at least on one side of the connection point. As a result, individual sections of the web-shaped flat material partially lie on top of one another. In this case, at least in the area of the

Overlapping also means that the relevant sections of the sheet-like flat material are connected to one another. At the same time, in the overlapping areas, the sections of the sheet-like flat material are also connected to the relevant structural part. This means that no additional connection is required in the areas where different sections of the sheet-like flat material overlap; rather, the fixing of the sheet-like flat material, which is required anyway, on the top of the structural parts to be connected, simultaneously serves to fix different sections of the flat material in the

areas of their overlap.

According to a preferred embodiment of the device according to the invention, the flat material is perforated. The flat material is then perforated strips or perforated tapes.

The perforation of the preferably web-shaped flat material is carried out by a plurality of through holes or bores. These preferably extend vertically through the top and bottom of the web-shaped flat material. The holes are preferably evenly distributed over the entire surface of the web-shaped flat material.

Preferably, several adjacent rows of holes are provided in the longitudinal direction of the web-shaped flat material.

arranged. The holes are preferably the same distance apart from one another. It is also advisable to offset the holes in the individual adjacent rows, preferably by half the distance between adjacent holes, so that the holes in one row are "spaced" from the holes in the other row. This creates a uniform grid of a large number of holes in the surface of the sheet-like flat material, which can be easily aligned, particularly in the overlapping area of several sections of the sheet-like flat material, in order to both connect the sections of the sheet-like flat material to one another in the overlapping area and to attach them to the top of the respective building part.

is The connecting means are preferably formed by at least one adhesive layer, nails and/or screws. When nails are used, these can be pushed through appropriately selected holes in the sheet-like flat material and hammered into the tops of the structural parts to be connected, if necessary without pre-drilling. A connection can also be made with screws, whereby the use of self-tapping screws can make pre-drilling unnecessary. However, it is also conceivable to screw the screws into pre-drilled holes, whereby a thread is expediently formed when screwing in.

By using an adhesive layer between the sheet-like flat material and the top of the building parts, a reliable, preferably full-surface connection between the sheet-like flat material and the top of the building parts is also created. Since the ring beam formed by the device is mainly loaded in a horizontal direction, the adhesive connection between the flat material and the top of the building parts, which usually absorbs relatively high shear forces, is sufficient. This connection can be further strengthened by the adhesive layer protruding fully or partially into at least some holes in the (sheet-like) flat material. Furthermore, combinations of different connecting means are conceivable, for example

for example, an adhesive layer with individual nails and/or screws. The additional nails and/or screws should preferably be arranged in areas subject to particular stress, for example in the edge areas of the structural parts to be connected that are adjacent to the respective connection point.

The invention further relates to a kit for forming a ring anchor from a sheet-like flat material, in particular with one or more sections of a flat material,

&iacgr;&ogr; and separate connecting means. The connecting means serve for the positive and/or frictional connection of the preferably web-shaped flat material with the building parts. The (web-shaped) flat material and the connecting means can be designed and placed on the top of the

The device shown here is used to connect structural parts. In particular, it is used to connect the tops of all types of walls in a horizontal direction. The device is used to replace conventional ring beams, preferably those made of reinforced concrete.

&iacgr;&ogr; In Fig. 1, a section of a building is shown schematically. It consists of two parallel walls 10 and 11 and a transverse wall 12 between the walls 10 and 11. The wall 10 can be, for example, an external wall of a building. The parallel wall

The wall 11 can be an interior wall. The wall 12 between the walls 10 and 11 has a sloping area 13 extending from the wall 10, which runs parallel to a roof structure of a sloping roof not shown in the figures. The wall 12, but possibly also the walls 11 and/or 10, can be made of prefabricated wall elements. In this case, the walls 10, 11 and 12 are not or only inadequately connected to one another at their vertical wall connections 14 and 15. The walls 10, 11 and 12 only stand on a floor or intermediate ceiling not shown in the figures. This is not sufficient to reliably connect the walls 10, 11 and 12, so that the upper sides 16, 17 and 18 of the walls 10, 11 and 12 must additionally be connected to one another against movements in the horizontal direction, which is what the device according to the invention is used for.

The device consists essentially of holding means and connecting means. According to the invention, the holding means are formed from a preferably web-shaped flat material or sections of the same. In the embodiment of the invention shown, the flat material is web-shaped perforated sheets 19, 20 and 21. The perforated sheets 19, 20 and 21 extend continuously over the upper sides 16, 17 and 18 of the walls 10, 11 and 12. The perforated sheets 19, 20 and 21 have a width that is approximately the same as the width of the walls 10, 11 and 12.

so that the perforated plates 19, 20 and 21 essentially completely cover the upper sides 16, 17, 18 of the walls 10, 11 and 12.

The perforated sheet 21 associated with the wall 12 extends over the vertical wall connections 14 and 15 between the walls 12 and 11 and 12 and 10. Opposite end regions 22 and 23 of the perforated sheet 21 extend over the perforated sheets 19 and 20 on the walls 10 and 11, so that the end regions 22 and 23 of the perforated sheet 21 overlap corresponding regions of the perforated sheets 19 and 20 on the upper sides 16 and 17 of the walls 10 and 11 to form overlap regions 24 and 25.

is The perforated sheets 20, 21 are provided with a large number of small through holes 26 and are thereby perforated. The through holes 26, all of which are of the same design, are arranged at equal distances in several rows running in the longitudinal direction of the perforated sheets 19, 20 and 21, respectively. Figs. 7 and 8 show a section of the perforated sheet 19. In the embodiment in Fig. 7, two parallel rows 27 with through holes 26 are provided. The distance between the through holes 26 in each row 27 is approximately the same. The through holes 26 of one row 27 are offset from the through holes 26 of the other row 27, preferably by approximately half the distance between adjacent through holes 26 in each row 27, so that the through holes 26 of one row 27 are spaced from the through holes 26 of the other row 27. In the embodiment of Fig. 8, the through holes 26 are arranged in three rows 28 running parallel to one another. Here too, the distances between the through holes 26 are approximately the same. The through holes 26 of the two outer rows 28 are located next to one another. In contrast, the through holes 26 of the middle row 28 are offset from those of the outer row 28 by half the distance between adjacent through holes 26. The through holes 26 of the middle row 28 are thus located at a gap with the through holes 26 of the two outer rows 28.

The perforated sheets 19, 20 and 21 are connected to the top sides 16, 17 and 18 of the walls 10, 11 and 12 by connecting means. Furthermore, in the overlapping areas 24 and 25, the end areas 22 and 23 of the perforated sheet 21 are connected to the perforated sheet 19 or 20. Consequently, in the overlapping areas 24 and 25, the perforated sheets 19, 20 and 21 are connected to one another and to the walls 10, 11 and 12, respectively. In this way, the perforated sheets 19, 20 and 21 bridge joints of the vertical wall connections 14 and 15 between the wall 12 and &iacgr;&ogr; of the wall 10 on the one hand and the wall 12 and the wall 11 on the other.

Fig. 4 to 6 show different connecting means for fastening the material strips to the upper side 16 of the wall 10.

In the embodiment of Fig. 4, a continuous adhesive layer 29 is arranged between the material strip and the top side 16 of the wall 10. The adhesive layer 29 connects the material strip over its entire surface to the top side 16 of the wall 10.

In the embodiment of Fig. 5, the perforated sheet 19 is connected to the wall 10 by an adhesive layer 30 and additional adhesive mass, which completely or partially penetrates at least some of the through holes 26 of the perforated sheet 19. In the embodiment shown, by pressing the perforated sheet 19 sufficiently hard onto the top 16 of the wall 10 while the adhesive has not yet hardened, the through holes 26 of the perforated sheet 19 are completely filled, so that studs 31 integrally connected to the adhesive layer 30 extend through the through holes 26. In this way, an interlocking connection of the perforated sheet 19 to the wall 10 is achieved, which effectively prevents horizontal displacement of the perforated sheet 19 on the top 16 of the wall 10 and also reliably prevents the perforated sheet 19 from detaching from the adhesive layer 30. Analogously, the perforated plates 20 and 21 can be connected to the walls 11 and 12.

&igr;&ogr;

In the embodiment of Fig. 6, the perforated sheet 19 is again connected to the top 16 of the wall 10 by an adhesive layer 32 and studs 33 that form the through holes 26. In addition, the perforated sheet 19 is connected to the wall 10 by nails 34. Each nail 34 is driven into the wall 10 from above through a through hole 26 of the perforated sheet 26 and the adhesive layer 32. If necessary, corresponding holes can be pre-drilled in the wall 10 for this purpose. For better hold of the nails 34 in the upper area of the wall

ao 10, the nails are provided with screw-shaped or thread-like projections. It is also conceivable to use self-tapping threaded screws instead of the nails 34. In the embodiment shown, the nails 34 serve to additionally connect the perforated sheet 19 to the wall 10,

is and preferably in places subject to particularly high stress. The perforation of the perforated sheet 19 and also of the perforated sheets 20 and 21 shown in Fig. 7 and 8 allows the nails 34 or screws to be positioned where they are required. It is also possible to hammer or screw a sufficiently large number of nails 34 or screws through the perforated sheet 19 into the wall 10. Finally, the perforation of the perforated sheet 19 also makes it possible to provide sufficient through holes 26 where nails or screws are to be used, even if the wall 10 or the other walls are made of prefabricated wall elements that have hollow spaces inside.

Alternatively, it is also conceivable to connect the perforated sheet 19 and also the other perforated sheets 20 and 21 to the upper side 16 of the wall 10 or other walls 11 and 12 exclusively by means of nails 34, screws or the like, so that the adhesive layers 29, 30 and 32 as well as the studs 31 and 33 can be omitted.

In the overlapping areas 24 and 25, where a connection of areas of the perforated sheets 19, 20 and 21 is required, nails 34 or screws are preferably provided, if necessary concentrated. In addition, it is also conceivable to connect the perforated sheets 19, 20 and 21 in the overlapping areas 24 and 25

19, 20 and 21 are to be connected to one another in certain areas by gluing. This can be done alternatively or in addition to nails 34 or screws.

Fig. 2 and 3 show an alternative connection of three walls 35, 36 and 37 of equal height with horizontal upper sides 38, 39 and 40. Here too, the walls 35, 36 and 37 are connected to vertical wall connections 41 and 42 by the device according to the invention, which forms a kind of ring anchor.

In the present case, however, only one continuous perforated plate 43 is used, which runs over the entire surface of the transverse wall 37 connecting the two outer parallel walls 35 and 36. The length of the perforated plate 43 is such that it protrudes on opposite sides of the wall 37,

namely, it extends across the vertical wall connections 41 and 42 across the walls 35 and 36. The perforated sheet 43 is not only connected to the central transverse wall 37, but rather the areas of the perforated sheet 43 that protrude on both sides of the wall 37 are connected to the walls 35 and 36, namely, they extend across the tops 38 and 39 of the walls 35 and 36. This creates the ring-beam-like connection of the walls 35, 36 and 37.

The connecting means shown in Fig. 4, 5 and 6 can be used as connecting means for fastening the single perforated sheet 43 to the upper sides 38, 39 and 40 of the walls 35, 36 and 37. Here too, it is conceivable to use only nails, screws or the like and, if necessary, only a layer of adhesive. If only a smooth layer of adhesive is used, as in the embodiment of Fig. 4, a preferably web-shaped flat material or sheet metal sections without through holes 26 can be used in place of the perforated sheet 43.

Modifications of the invention that differ from the embodiments shown are conceivable, whereby the perforated sheets, unperforated, sheet-like sheets or sheet sections are profiled, i.e. do not have a flat shape. The profiling can be in the form of beads, which serve to ensure that the

Sheet metal cannot warp and therefore cannot become detached from the tops of the walls. Such profiled sheet metal is particularly suitable for adhesive bonding to the tops of the walls, with the beads or other bulges in the sheet metal forming adhesive pockets.

Alternatively, it is also conceivable to provide the sheet with projections or formations in certain areas, which are designed to correspond to recesses or cavities, as are often found in prefabricated wall elements. These deformations of the sheet, which engage in cavities or recesses in wall elements, serve to create a particularly durable and permanent form-fitting connection of the sheet or sheet sections with the top of the respective wall or the

is the respective wall element. This allows walls or wall elements to be connected particularly effectively.
