    The wall connection element (1) according to the invention has a cubic insulation body (4), in the four corner regions (9) of which pressure elements (7) are arranged. In the area between the pressure elements (7) are three transverse force-transmitting rods, which are designed as a bracket (10) arranged. These brackets (10) have free legs (11), which come to rest in the installed state in the wall (2), and an end formed into a loop (13), which comes to rest in a floor-ceiling plate (3). Two brackets (10) extend with the loops (13) perpendicular to the wall longitudinal direction and one in between in the wall longitudinal direction. This solution is inexpensive to produce and suitable both for the transmission of static and dynamic forces.

    专利说明:

    The present invention relates to a wall connection element for thermally-insulated connection of a concrete-cast wall with a concrete-cast floor cover plate, comprising a cubic insulation body with a first in the installed position to floor ceiling plate facing support surface and an opposite, executed in the installed position to the wall , Second bearing surface and at least one pressure element and transverse forces transmitting rods that pass through the insulation body.
    From EP 2 405 065 a wall connection element of the type mentioned is known. It shows a cubic insulation body with a first and a second bearing surface and a pressure element arranged centrally therein. Also present are transverse force transmitting rods, but enforce the pressure element here. This requires that the transverse force-transmitting rods must be passed through a mold during production through which is filled with concrete and this is very complex in terms of handling. The rods must be kept in correct position above and below the pressure element and the form sealed against the rods carried out. Such a production is time consuming and expensive. In addition, however, that these rods must be inclined in the implementation of the insulation body in order to absorb the transverse forces can. In the mentioned patent also solutions are shown, in each case a rod is guided straight through a pressure element. However, such straight rods do not serve the transverse force absorption, but only to absorb the compressive and tensile forces on the connection element. However, the patent also shows solutions according to FIGS. 11a, 11b and FIG. 8 in which the bars consist of U-shaped bent temples, which, however, each lie in the pressure element with their point of intersection. Such an embodiment is even more complex to manufacture.
    In addition, only offset symmetrically to the center axis of the insulating body towards the center arranged pressure elements are present or are mounted only centrally in these insulating bodies. This causes the supporting base of the wall rests limited only to the base of these pressure elements and thus is narrower than the wall is wide. The smaller the pressure body is, the lower the bearing surface area of the wall and the correspondingly larger is the expected tilting element under dynamic loads in the transverse force direction. In order to solve this problem, in the known embodiment, the pressure element would have to be the same size as the width of the wall. Although this is possible in itself, but then the thermal insulation of the wall to the ground cover plate is completely lost. In an obvious way, from the known embodiment according to the European patent EP 2 405 065 this problem of a statically correct and thermally meaningful solution, which can also be dynamically effective, can not be realized.
    Another solution shows the German utility model DE 9 413 502.9 U. Here, a structural element for thermal insulation in masonry is proposed, with a cuboid heat-insulating body, which is interspersed for load transfer in the vertical direction of many supporting bodies, extending between a lower and an upper support surface. The support bodies have a plurality of vertical support columns, which are interconnected by webs. Such a device is a thermal partial separation, but is not designed for the transmission of shear forces between a wall and floor tile panels.
    Similarly, EP 2 151 531 also shows a heat-insulating brick, which is just as unable to solve the problems involved here. Ultimately, cantilever plate connection elements are known which have an insulation body which is penetrated by both tensile and compressive forces transmitting rods as well as transverse force-transmitting rods, both sides of the bearing surfaces of the insulation body end plates are present, which allow a pressure distribution. But such cantilever elements are used to connect a floor ceiling plate with a cantilever, for example, a balcony. For the connection of a floor-ceiling plate with a vertically extending wall Kragplattenanschlusselemente are not suitable.
    It is therefore the object of the present invention to improve a heat-insulating wall connection element according to EP 2 405 065 so that the aforementioned problems can be avoided and can also be effective dynamically.
    This object is achieved by a wall connection element of the type mentioned with the features of claim 1. Further advantageous embodiments of the subject invention will become apparent from the dependent claims and their meaning. The operation will be described in the following description with reference to the accompanying drawings.
    In the drawing, a preferred embodiment of the subject invention is shown. It shows:<Tb> FIG. 1 <SEP> a side view of the inventive wall connection element in the direction transverse to the wall longitudinal direction and<Tb> FIG. 2 <SEP> the same wall connection element in turn viewed in a side view in the view to the wall longitudinal direction.<Tb> FIG. 3 <SEP> shows the wall connection element with view from below of the first, to the floor ceiling plate support surface.<Tb> FIG. 4 <SEP> shows a lateral force transmitting bar alone during<Tb> FIG. 5 <SEP> shows a printing element in itself in a side view and<Tb> FIG. 6 <SEP> this pressure element rotated by 90 °.<Tb> FIG. 7 shows a possible laying arrangement of a plurality of wall connection elements according to the invention of different lengths.
    The inventive wall connection element is designated overall by 1. This element 1 connects a concrete-walled wall 2 with a concrete-floored ceiling slab 3 extending perpendicularly to it. These can be either internal or external walls. Both static and dynamic forces can occur in the joints between the floor slabs and the walls. In the case of static forces, these are compressive forces on the one hand and lateral forces that occur on the other hand. This also applies to the dynamic forces. Such dynamic forces occur not only in earthquakes, but also in machine shops where there are machines that can cause vibrations and vibrations in all directions.
    The wall connection elements 1 of interest here should in particular have a heat-insulating effect. Accordingly, such wall connection elements have insulation bodies 4. These insulating body 4 have a first bearing surface 5, which is directed towards the floor ceiling plate and a second bearing surface, which is directed towards the wall. In the insulation body 4, four or more pressure elements 7 are present. These pressure elements 7 are arranged at least in each of the four corner regions 9 of the insulation body 4. Depending on the length of the wall connection element 1, further pressure elements 7 may be present between these four pressure elements 7, which are arranged on two opposite outer surfaces of the wall 2. In any case, four printing elements 7 each form a rectangle. 7 shows an arrangement in which, with reference to the drawing on the left, a wall connection element 1 with four pressure elements 7 is shown, followed directly by a wall connection element 1, which here has six pressure elements 7, while on the right-hand side a wall connection element 1 is arranged with four printing elements 7. Always four directly adjacent printing elements 7 define a rectangle. The wall connection elements 1, 1 can be arranged directly adjacent to each other juxtaposed or in between pure insulating body 4 without pressure elements. The per se inherent transverse force-transmitting rods 8 are not shown here for the sake of simplicity, although these are of course available.
    With reference to FIGS. 1 to 3, a preferred embodiment of the inventive wall connection element 1 will now be explained in detail. Each wall connection element 1 always consists of three different parts, namely an insulation body 4, at least four pressure elements 7 and at least three transverse force-transmitting rods 8. These three different components for forming a wall connection element according to the invention will be briefly discussed below. The cubic insulation body preferably consists of a high-performance insulation for thermal insulation, which is also pressure-resistant. In particular, sheets of closed-pore foamed polyurethane or extruded polystyrene rigid foam sheets are suitable for such insulation bodies. These panels have a closed foam skin and thus absorb virtually no moisture. This material has been particularly suitable for use in the field of foundations, earth-contacting walls or basement floors and can also be used in heavily loaded floors in the industry.
    For the production of transverse force-transmitting rods 8, it is preferable to start from stainless steels. These are so-called round steels, which are usually ribbed. In Fig. 4, such a transverse force transmitting rod 8, which is first formed into a U-shaped bracket 10 is shown. Such a U-shaped bracket 10 has two parallel free legs 11 which are integrally connected to each other via a connecting web 12. By a relative to a central longitudinal axis 15 made twisting of the connecting web 12, a loop 13 is formed. Here, each of the two free legs 11 is deformed by two kinks 16, so that form two so-called Z-angle a, which are each the same size and about between 30 ° and 45 °. The loop 13 thus forms approximately a pentagon, wherein the connecting web 12 and the lateral rod portions 17 extend approximately perpendicular to each other. In the finished bent state now continues the continuation of the left free leg 11, as a lateral rod member 17 on, with this right lateral rod portion at least approximately flush under the right free leg 11 comes to rest, while the continuation of the right free leg 11 as a lateral rod portion 17th the loop 13 comes to rest under the left free leg 11. Between the free legs 11 and the loop 13 is located on the central longitudinal axis 15 of the bracket 10, a crossing point 14th
    With respect to the printing elements 7 used here, reference is made to FIGS. 5 and 6. Such pressure elements, which are preferably made of ultra-high-strength concrete, is also referred to the European patent application EP 2 354 343. This patent application of the same applicant already uses such pressure elements for support plate connection elements.
    The pressure element 7 shown here is formed of two truncated pyramids 70, whose top surfaces are directed towards each other and here are integrally connected to each other via a connecting piece 71. At the bottom surfaces of the truncated pyramids 70 head-foot plates 72 are formed. Their base surfaces form the pressure surfaces 73. The base of the truncated pyramids 70 are rectangular and could in principle be square, but here these bases have a longitudinal edge and a broad edge, which have different lengths.
    Coming back to the illustration in Figs. 1 to 3, the relative arrangement of these above-described components of the wall connection element 1 will now be described relative to each other. In the finished state, the pressure elements 7 in the insulation body 4, in the corner regions 9, arranged. The pressure elements 7 can be arranged in the insulation body 4 so that two adjacent side edges of each pressure element coincide with two adjacent side edges of the cubic insulation body 4. As a result, the optimally largest footprint or support surface of the wall is achieved on a floor ceiling tile or a floor tile on the wall. The side edges, which in principle correspond to the side edges of the head foot plate 72 of the pressure elements 7, are only apparent in the plan views, that is to say in FIGS. 3 and 7. Since ultra-high-strength concrete is relatively brittle and impact-sensitive, it is useful and therefore provided in a preferred embodiment that those side edges 75- of the pressure elements 7, which extend in the longitudinal direction of the wall, from a protective edge 40, which is part of the insulating body is covered. This version, in which a protective edge 40 as part of the insulating body 4 protect the pressure elements 7 made of ultra-high-strength concrete, can only be seen in FIG. 3. This version reduces the maximum footprint only insignificantly. As already mentioned above, however, two adjacent side edges 75 can also lie completely outside. In this case, one will only surround the insulating body 4 with a circumferential plastic strip 41. As a result, the pressure elements 7 are held relative to the insulating body 4 and protected at the same time. After installation, these outer parts of the plastic strip or the strapping can be removed. However, this may not be necessary to be removed, depending on the further layers to be applied to the wall.
    Within the space defined by the four pressure elements 7, but outside of these pressure elements 7, extend the specially formed bracket 10, consisting of the free legs 11, the connecting web 12 and the loop 13. In this case, as shown in FIG and Fig. 3 it can be seen, two such bracket 10 perpendicular to the longitudinal direction of the wall 2 and a third bracket 10, between these two perpendicular to the direction of the wall arranged bracket 10, in the direction of the wall in the center plane 18. All crossing points 14 of each three brackets 10, which are arranged between four adjacent, a rectangle defining area, run or are aligned so that their crossing points 14 lie on the median plane 18 of the wall 2.
    The loops 13 of the bracket 10, which lie only with their tip to the intersection point 14 in the insulation body 4, are thus almost completely within the ground cover plate 3, taking into account a sufficient concrete overlap of the connecting webs 12, can be achieved.
    Since the transverse force-transmitting rods 8 and the bracket 10 are not passed through the pressure elements 7, flakes on the pressure element 7 in the area in which such transverse force-transmitting rods would escape from the pressure element 7, avoid. In addition, the freedom of movement of the transverse force-transmitting rods 8 is completely preserved, so just dynamic loads can be worn.
    As can be seen from Figs. 1 and 2, the free legs 11 may be longer for those straps that extend completely in the central longitudinal plane 18 of the wall 2, as those free leg 11 or bracket 10, which is perpendicular to the direction the wall are arranged.
    A great advantage of the inventive solution is just as already mentioned, is that the transverse force-transmitting rods 8 need not be guided by the pressure elements 7. The implementation of the insulation body 4 is completely unproblematic. For this purpose, you bring only in the required places slots in insulation body 4, the width of which is less than the rod thickness, so that after insertion the bracket 10 are positively and positively held in the insulating body 4. The attachment of such slots can be attached mechanically or by cutting by means of a laser beam. Due to the existing elasticity of the material, the transverse force-transmitting rods are absolutely fixed enough. A tightness in the transition area is by no means required. The concrete or concrete milk entering during installation of these wall connection elements, in the region of the feedthrough slots, only slightly increases the bending stiffness of the bars. This increases the more substantial static strength in most cases, but hardly changes the dynamic strength.
