Abstract

The element has reinforcing elements (7) passing-through a partition plate (3) that comprises a through hole. The partition plate has a trough-shaped shell body (4) in a region of the through hole, where the shell body is projected from the partition plate in one of two adjacent building parts (A, B). The reinforcing elements are projected from the other adjacent building part under transition of another through hole in the shell body. The reinforcement elements are supported at the partition plate and/or the shell body.

Description

The invention relates to a component for installation in joints of buildings, in particular in the range of staircases, the sound-absorbing, force-transmitting connection on both sides of adjacent building parts, consisting of a partition plate and from these traversing reinforcing elements, wherein the partition plate has at least one opening for a reinforcing element.

Such components are for example from the DE-A 195 42 282 known. Here, a hard partition plate is used with a multi-layered structure of relatively hard outer layers and a contrast soft liner and without direct connection of the two outer layers together and cast in the parting line between two parts of the building. The reinforcing rods are passed through openings provided in the partition plate and anchored in the soft intermediate layer of the partition plate in the component, which dampens the vibration transmission between the outer layers with each other and between the outer layers and the reinforcing bars. The disadvantage here is that the reinforcing rods despite their attenuation relative to the component because of their passing through the partition plate, the two parts of the building interconnecting course nevertheless cause a sufficiently large vibration transmission and thus sound or noise transmission between the building parts. In addition, the arrangement of the rods in the soft intermediate layer leads to a correspondingly large thickness of the component and accordingly to a large mutual distance of the adjacent building parts.

To avoid such passed through a partition plate reinforcing rods that extend between the two adjacent parts of the building and thus even provide an additional sound transmission despite the to be provided by the device sound insulation itself, was in the state of Technology in the EP-A 1 760 209 proposed to let rebars do not pass through the partition plate, but only set laterally on the partition plate, the partition plate used to ensure the power not only the reinforcing bars, but by a stepped cross-section and a mutual overlap of the adjacent building parts in the vertical direction.

In this embodiment, the partition plate is very complex and has not only separate holding means for positionally accurate determination of the reinforcing bars, but also a coextruded multilayer structure in which optionally additional elements such as fire protection strips, elastomeric bearings, etc. are to be installed and by the stepped course self-supporting and must be stabilized with several inner webs. If this construction is already comparatively complicated and the associated production outlay is correspondingly large, then the stepped embodiment of the partition plate with inclined dividing plate legs additionally leads to the absence of a defined vertical dividing plane between the adjacent building parts; Rather, the parting plane in the known case, the corresponding stepped partially inclined course, which leads to an extremely low tolerance in the installation of the known device for sound insulation: Would the device, for example, be installed a bit too high or too low or with different height compared to the height the adjacent building parts, so led the inclined partition sections very quickly that the parting line formed on the top of the adjacent building parts is not congruently positioned with the parting line on the bottom or that at least one of the joints near the edge, if necessary inclined instead of vertically, which quickly Problems with the connection work z. B. the application of a screed, flooring, insulation, etc. leads.

In addition, that is from the EP-A 1 760 209 known component for installation in joints not or suitable only under difficult adaptation measures to be installed at other positions with the same task: So it would be problematic to use the known device to store a stair landing on a building ceiling or on a building wall of a staircase, there this by the stepped course of the dividing plane would lead to the building ceiling or the building wall would have to extend beyond the actual vertical parting plane in the direction of the stair landing. As a result, the building ceiling or building wall would no longer have a defined planar end face, which is undesirable and can lead to consequential problems in calculations, connection work, etc.

On this basis, the present invention seeks to further develop a component for installation in joints of buildings according to the preamble of claim 1 to the effect that it allows a modular design and thus a simplified adaptation to respective installation conditions and thereby for other applications with the same task , namely sound-insulated transmission can be used.

This object is achieved by a component for installation in joints of buildings with the features of claim 1.

Advantageous developments of the invention are the subject of subclaims, the wording of which is hereby included by express reference in the description in order to avoid unnecessary text repetitions.

According to the invention, the component for installation in parting lines of buildings, characterized in that the partition plate in the region of the opening has a trough-shaped shell body projecting from the partition plate in the first of the two adjacent parts of the building, that the reinforcing element, starting from the second of the two building parts by traversing the opening protrudes into the shell body and that the reinforcing element is fixed to the partition plate and / or the shell body.

By dividing into a partition plate on the one hand and one or more shell body on the other hand, a modular design is possible, which brings a separation of functions with it: Although the partition plate can basically have any shape, but it is now possible, even in the simplest basic form flat and without Trains etc., which not only reduces the cost, but also in terms of assembly, connection work, etc. is particularly favorable. The partition plate according to the function separation according to the invention thus only for a sound-insulated spacing of the two adjoining building parts, whereas for the power transmission alone the scarf body is responsible, which is installed in corresponding openings of the partition plate and fixed there: Of course, the scarf body does not guarantee the power transmission alone, but this purpose uses the reinforcement element passing through the opening and a surrounding the reinforcement element Concrete material that extends into the shell body. The special feature is that - as in the prior art of DE-A-195 42 282 - The reinforcing element passes through the opening of the partition plate, but does not extend into the adjacent second part of the building (ie not in the material of the second part of the building), but is limited to the area of the shell body. In this case, an overlap of the two adjacent building parts is created only in the area of the scarf body, but - with appropriate dimensioning or number of shell body - sufficient to provide the required power transmission.

It is easy to see that the shell body with associated reinforcement element on the one hand and the partition plate on the other hand easily with respect to position, size, etc. can be adapted to each other. So you can, for example, with one and the same partition plate, which must be based only on the appropriate height of the adjacent parts of the building, a transfer of great forces by installing appropriately sized shell body or a correspondingly large number of shells as well as the transmission of only small forces, including can then be worked with a few or relatively small sized scarf bodies and reinforcing elements. The only adjustment of the partition plate must be to adapt the opening in terms of size and position to the installation case and the number and dimension of the connected Schalkörper.

In this context, it is advantageous if the reinforcing elements consist of reinforcing bars and the reinforcing bars are at least in part areas in particular ironed and / or loop-shaped. Thus, the area within the shell body can be optimally reinforced and also the transmission of tensile forces is ensured by the bent or loop-shaped course within the shell body.

An essential embodiment of the invention is that the reinforcing element together with a surrounding concrete material to form a console-like bearing projection for the second of the two parts of the building, this second part of the building extends by means of the bearing projection in the shell body and so in the first building part to each other Overlaying the two building parts protrudes. Thus, the console-like bearing projection, which is indeed associated with the second part of the building and extends into the first part of the building, forms exactly the overlap that is required for the mutual power transmission without the need for reinforcing bars - as in the prior art of DE-A-195 42 282 - To extend from the first part of the building into the second part of the building and without even that the overlap by a particularly complicated design of the partition plate - as in the example of EP-A-1 760 209 - must be made available.

The trough-shaped shell body is designed to be open on one side in the direction of the second of the two parts of the building and separates the first and the second building part by a closed trough-shaped surface from each other. Thus, the existing between the two parts of the building in particular vertical parting plane is provided with these bulbous or trough-shaped protuberances, which extend into the first part of the building, but without this having an effect on the course and especially on the shape of the remaining parting plane in the Separating plate provides.

The component according to the invention can be used in different ways: It is particularly advantageous if the first of the two building parts rests on a bearing projection which is assigned to the second of the two building parts via a ceiling surface of the scarf body arranged in the region of the upper side of the scarf body. This may be the case, for example, if a flight of stairs is to be stored as the first part of a building on a landing step as the second part of the building; then the shell body would extend into the flight of stairs and the flight of stairs would rest on the top of the scarf body and so transferred the force on this top of the scarf body and provided in the shell body bearing projection of the stair landing.

However, the component can also be used in that the second of the two building parts rests on the first of the two parts of the building by means of the bearing projection assigned to it via a bottom surface of the scarf body arranged in the region of the underside of the scarf body. Thus, while in the aforementioned example the scarf body extends into the area of the supported building part, in the subsequently described second variant with a support in the area of the bottom surface of the scarf body the scarf body would extend into the supporting building part. This could, for example, in the described installation between a flight of stairs and a landing so that the shell body extends into the landing, so that the bearing projection is assigned to the flight of stairs and extends into the shell body and so the forces on the bearing projection and the bottom surface of the Schalkörpers be transferred to the landing.

It is now possible to select two installation situations at each installation site (on the one hand, assigning the bearing projection to the supporting building part and supporting the supported building part on the bearing projection of the supporting building part via the ceiling surface of the shell body, whereby the shell body extends into the supported building part; the bearing projection to the supported building part and supporting the supported building part with its bearing projection on the bottom surface of the scarf body, wherein the shell body extends into the supporting building part), so that, for example in a flight of stairs four different variants can result (1st variant: the bearing projection is assigned at the top and at the bottom of the staircase; 2nd variant: the bearing projection is assigned at the top and at the bottom of the stair landing 3. Variant: the bearing projection is at the upper end of the flight of stairs and at the lower end of the stair podium assigned; 4th variant: the bearing projection is at the bottom of the staircase and at the top of the stair landing associated); Nevertheless, it is usually preferred for reasons of installation, to arrange the bearing projection at both installation sites the same, ie in the nature of said first variant or said second variant.

If, after all, individual parts of the building, in particular the staircases, consist of semi-finished parts (eg filigree plates ^™ ), it is for reasons to prefer the better connection and structural behavior, assign the storage projections this semi-finished parts and to arrange the formwork body in each of the other parts of the building.

Furthermore, it is possible to arrange the partition plate between a building ceiling or building wall on the one hand and a stair landing or a stair part on the other hand. Again, the parting plane may be vertical and e.g. flush with the face of the building ceiling and the shell body can then - as desired - in the worn or in the supporting part of the building extend into it.

This versatility of the same component for different installation situations shows the particular advantages of the subject invention.

It is furthermore particularly advantageous if the trough-shaped shell body consists at least of a curved trough element for receiving the substantially horizontally extending reinforcing element and the surrounding concrete material and a substantially in the particular vertical partition plate plane extending edge and if the shell body in Area of the edge is attached to the partition plate in the region of their openings. The attachment can be done by clamping, latching or clip connections, but also by cohesive adhesive or welded joints.

The trough shape must of course be sized so large that the surrounded by the shell body console-like bearing projection is strong enough to ensure the required power transmission. In this case, certainly a variety of Schalkörperformen in question, which are described in the present case lumpy with "trough-shaped", which should mean, in particular, that the parting plane in the region of the Schalkörpers bulbous or just trough-shaped and thus deviates from the other flat course of the separation plate. The term "trough shape" used here is therefore not intended to determine the exact spatial form; Rather cubes are possible with flat side surfaces as well as deviating body with curved or inclined side surfaces, etc., as well as wedges, cylinders, trapezoids, etc. All common and thus the "trough shape" corresponding to the unilaterally open training, which ensures that the shell body is connected to the partition plate in the region of an adapted to the shell body opening and that while the parting plane in the region of the shell body from the partition plate plane in the dummy body plane, ie the plane of the mantle shell is laid.

In this context, it is important that the shell body is constructed with two or more shells or two or more components and has an insulating element, in particular in the form of an elastomeric layer, disposed between the shell shells, at least in partial areas, for mutual insulated transmission of force. As a result, the power transmission can be combined with the required sound insulation, but without the reinforcing element would have to extend between the two parts of the building to do so.

In this case, the insulating element - depending on the application - to arrange at least in the area of the ceiling and / or bottom surface, namely at least where the power transmission takes place. Of course, it would be quite possible to provide the entire shell body with an elastomer layer, but this would be unnecessarily expensive. And if the other two- or multi-shell construction ensures that no sound bridges between the two shells are present, then the existing between the two shells air is sufficient as a sound insulation material.

In the described embodiment, the bivalve structure of the scarf body is actually formed in a particularly optimal manner that no direct connection between the two shell shells is provided, but that alone on the insulating element, so the elastomeric bearing a mutual soundproof system is available, which is for the required power transmission ensures and otherwise for the required positional fixing or mutual assignment of the two shell shells.

Instead of two equidistantly extending flat shell shells, a flat shell shell could be combined with an insulating layer (eg in the form of a PE foam panel) in an equally advantageous manner, wherein these two components can be connected to one another over the entire surface, in particular adhesively bonded.

The same applies to the separating plate, which can also be constructed from a flat first wall and an insulating layer fixed thereto (for example in the form of a PE foam plate), wherein these two components can in turn be connected to one another over the entire surface, in particular adhesively bonded.

Although it is already in the prior art from the DE-A-195 13 664 known to use cuboid shell body for soundproofed Auflagerung of storage projections and to supplement them in the region of a parting line with Dämmstreifen of sound insulation material; However, these can be due to their design and dimensioning only in building walls bring in which the component height is not limited, and combine with corresponding storage projections of a staircase made of in-situ concrete or prefabricated elements. By no means, however, are they suitable for being inserted into any kind of parting line between two adjoining building parts. So they can not be installed, for example, especially in a parting line between a flight of stairs and a landing, since there the component height is so low that the required anchorage of the scarf body fails because of the lack of concrete and undercover and thus is not possible.

In this document, it is even suggested that the shell body has up to the top of the component extending edge strip, that is, in this document, the way is exactly away from a modular design towards a one-piece complete system, which is avoided or improved by the present invention shall be.

An essential advantage of the present invention comes into play when the reinforcing element is fixed in the region of the top of the scarf body on the scarf body edge and / or on the partition plate. Because then you can ensure the required exact positioning of the reinforcing element in the shell body without adjacent components would have to be included in this positional fixation and positional positioning. Thus, for example, the reinforcing element, starting from the shell body or Schalkörperrand or protrude from the partition plate first in said second of the two parts of the building, then be bent in said second part of the building and from there back towards the first part of the building to the shell body in order to there again preferably with distance to the shell body wall its final position in which it can be enclosed on all sides by the concrete material of the second part of the building, so as to form said console-like bearing projection.

Of course, the reinforcing element can be guided and fixed over, for example, a plastic web with respect to the shell body wall so as to ensure the required concrete cover for both static and corrosion protection reasons. Suitably, the reinforcing element is bent in a loop shape in the projecting area in the shell body, there not only to enter into a better bond with the concrete material surrounding the reinforcing element, but also to be able to better absorb occurring tensile force components.

As regards the determination of the reinforcing element on the material of the partition plate or on the shell body or on the edge of the scarf body, for example, holding plastic receptacles may be formed on the partition plate or the scarf body edge, in which the reinforcing element can be inserted, clipped or fixed in any other way. In this case, the Festlegungsart should be designed so that in fact a secure positional fixation of the reinforcing element with respect to the shell body and / or the partition plate can be done to the predetermined position of the reinforcing element within the shell body even with occurring loads during transport, installation on the site or the Loading by in-situ concrete not to be impaired. Even against this background, it makes sense to additionally set the reinforcing element in the area within the scarf body by said plastic web at a further point.

The essential aspect of the present invention is - as already mentioned - in the modular design. Against this background, it is particularly expedient that the component has a plurality of openings provided in the partition plate, a plurality of shells arranged side by side, in particular in the region of the openings, and a plurality of reinforcement elements, which extend into the corresponding shell body. This makes it possible to adapt the component to the respective application or load case and to exploit the desired and inventive modular structure. After the device according to the invention is to be arranged in the joint area between stair landing and stairs, it is subject to strict specifications in terms of height, so that the shell body can not be sized arbitrarily, but instead a larger power by a correspondingly large number of Schalkörpern available must be made. In a preferred embodiment, the component according to the invention is used, for example, at a partial building height of 160 mm, the shell body has a concrete cover of 50 mm above its arranged on its top surface Dämmelements, with a horizontal projecting into the first part of the building shell body depth of about 80 mm and a horizontal Schalkörperbreite of almost 100 mm. In order to enable a sufficiently large power transmission, every 150 mm horizontally next to each other a shell body is arranged so that six shell body can be provided in a partition plate with a horizontal length of 1000 mm.

Another advantage of the present invention is to be seen in the fact that the inside of the trough-shaped scarf body has at least in partial areas of the top for venting a concrete material to be filled into the shell body a sloping or curved course, so that it is ensured in any case that the concrete material surface and completely rests against the ceiling surface of the scarf body, in the area of the force-transmitting insulating element is positioned. For the corresponding power transmission between the building parts with the interposition of the Dämmelements, it is essential that the entire Dämmelementfläche can be used for power transmission and there not worry about air bubbles in the concrete material for reduced power transmission surfaces. The curvatures or inclinations or curvatures of this ceiling surface can be designed so that any air bubbles present in the concrete are discharged laterally into a region outside the Dämmelements where no areal conditioning is required because there no or hardly any power transmission must take place in the corresponding edge region ,

Of course, this mentioned problem of the air bubbles present in the concrete material plays a role, especially when filling the scarf body with in-situ concrete, namely when the scarf body is filled with the in-situ concrete material of the second building part only at the construction site. Likewise, however, air bubbles may naturally also accumulate in the concrete in the production of the console-like bearing projections in a precast plant, so that an inclined or curved course of the ceiling surface in the region of the upper side of said shell body is also advantageous for such an application.

In this context, it should be particularly noted that the present invention can be exploited not only for use of the device according to the invention on the site and a corresponding filling of the shell body or creating the first and second building part of in-situ concrete, but that the present invention also particularly advantageous and effective for use when the console-like bearing projection consists of a precast concrete component, wherein the concrete material is filled in serving as a mold shell body under the action of the associated reinforcement element and mounted on the construction site together with the shell body in the region of the parting line to be created becomes.

In this case, it is particularly recommended that the console-like prefabricated storage projection at least partially fills the area of the scarf body and is limited to this area and not flush with the partition plate level to achieve a positive fit of the in-situ concrete with the bearing projection in the vertical direction, but in contrast at least something ends back into the shell body. At the construction site, the in-situ concrete of the second building part can then be cast in a particularly simple manner against this prefabricated console-like bearing projection, the in-situ concrete projecting partially into the shell body - in addition to the reinforcing element projecting into the second building part - for the necessary mutual anchorage of the storage projection and the second building part provides.

In this case, the prefabricated concrete component end face either - with respect to the orientation in the installed state - in the vertical direction or advantageously with inclined, with its lower end to the rear into the insulating body inside staggered. The inclined course has the additional advantage that also here a venting of the in-situ concrete can take place by the ascending air bubbles can not collect in the insulating body or the storage projection, but by the inclined course of the end face of the finished part forward from the insulating body and thus led the storage lead.

In addition, the shell body can also be completely filled by the console-like prefabricated storage projection, the finished concrete component end face terminates in particular flush with the Schalkörperrand. This results, for example, in the advantage that the in-situ concrete does not act on the inside of the scarf body and thus does not have to be provided for a venting of the in-situ concrete in this area.

Finally, in particular in the region of the separating plate, the component can be provided in a manner known per se with a fire protection material, e.g. with a strip of intumescent material placed in a recess of the separator plate and / or in terminal end caps for lateral, i. terminal closure of the partition plate is arranged.

In FIG. 1a is a component 1 for installation in joints of buildings shown in side view, which is arranged between two adjacent building parts A, B in the form of a staircase B as the first part of the building and a landing A as the second part of the building. Stair run B and stair landing A are shown in excerpts and in sections and have schematically indicated structures 2a, 2b in the form of floor coverings such as tread plates, screed, impact sound insulation, floor tiles, etc. Between building part A and part B of the building a parting line C is arranged, which extends vertically over the entire height of the building parts and the corresponding structures 2a, 2b and not only represents a construction joint, but must also provide a footfall sound insulation between the adjacent thereto components.

FIG. 1b shows a second exemplary application, in each case the same components are provided with the same reference numerals and the component 1 is again shown in side view between two adjacent building parts 8, 9 in the form of a flight of stairs 9 and a landing 8, but here the staircase as the second part of the building A and the landing step acts as the first building part B, so the component is used in a precisely reversed application. For this purpose, the component 1 is installed quasi upside down.

In the area of the two parts of the building A, B is (this applies per se for both applications - however, the invention is to avoid confusion based on the embodiment of the following FIG. 1a described) a planar partition plate 3 is arranged, which extends over the entire height of the adjacent parts of the building and - in particular from the FIGS. 2 and 3 recognizable - has a horizontal length in the order of, for example, 1 meter, which corresponds to the length of the parting line C and thus the width of the staircase B. The dimensions of the partition plate 3 are in FIG. 2 with the letters h (= vertical height), I (= horizontal length along the parting line) and b (= width of the separating plate in the horizontal direction, which essentially corresponds to the width of the parting line).

The partition plate has a plurality of horizontally extending and a few millimeters projecting lips or webs 3I, which provide for a certain anchoring of the partition plate in the adjacent concrete of the building parts A and B. Incidentally, the partition plate 3 consists of two relatively pressure-resistant outer walls 3a, 3b, which are interconnected only via three horizontal intermediate webs 3c and otherwise maintain a mutual distance in the order of about 10 mm, thereby the two adjacent building parts A and B. Keep apart from each other and prevent a corresponding mutual investment and thus vibration and sound transmission. The outer walls 3a, 3b with the intermediate webs 3c are self-supporting and pressure-stable enough to withstand the forces of the liquid concrete material, if the building parts are made of in-situ concrete or prefabricated in prefabricated concrete and even after curing of the concrete material to keep both parts of the building permanently at a distance.

The partition plate now has according to the invention a plurality of juxtaposed openings 3f, in the trough-shaped shell body 4 (respectively in the same direction) are inserted, wherein the shell body 4 each have a peripheral edge 4h, the flat, liquid-tight system and fixing the respective shell body relative to the Separation plate 3 is used. These scarf bodies are particularly accurate in the FIGS. 4 to 9 and will accordingly be described below with reference to these figures:

A shell body 4 consists of two trough-shaped shell shells 4a, 4b, wherein the inner shell 4a is assigned to the building part A and the outer shell 4b the building part B. Each shell has the said peripheral edge 4h and a bulbous or curved trough element 4j. In this case, the inner shell 4a is acted upon in particular in the associated trough element 4j from the concrete of the building part A from the inside, while the outer shell 4b is acted upon by the concrete of the building part B, in particular with respect to the associated trough element 4j from the outside. Between inner shell 4a and outer shell 4b is - as especially from the FIGS. 4a, 4b, 4c in the vertical section is visible - arranged in the upper area, the so-called shell body ceiling surface 4c, an insulating element 5 in the form of an elastomeric bearing, which ensures the sound-insulated transmission of power between the building part B and building part A. In the area of the inner shell 4a, the elastomer bearing 5 lies flat on the outer upper side 4k of the inner shell 4a, whereas the elastomeric bearing 5 acts on the outer shell 4b in the area of its upper side 4I from below. Thus, outer shell 4b, elastomer bearing 5 and inner shell 4a lie against each other over the entire surface, as can be seen in particular from FIGS FIGS. 7, 8 and 9 which shows a section through the elastomer bearing or a front view of the elastomer bearing.

From the sectional views of FIGS. 7, 8 and 9 and also from the sectional views of the FIGS. 4a, 4b, 4c It can be seen that otherwise the inner shell 4a and the outer shell 4b in the embodiment shown have no further points of contact with each other, but rather in a mutual equidistant distance of, for example, 5 mm and thus form an air gap which is sufficient to take place in the region of the elastomer bearing soundproofed Auflagerung the building part B on the building part A not to be affected.

The FIGS. 4 to 9 and also the perspective representations in the FIGS. 2 and 3 let the trough shape of the Trogelements 4j of the scarf body 4 recognize, where it arrives above all on the top or ceiling surface 4c of the scarf body, in which the described elastomer bearing 5 is arranged as an insulating element. The rest of the trough shape is not primarily relevant for power transmission and sound insulation; the illustrated shell body 4 extends in its lower portion obliquely sloping in the direction of the building part A and Thus, it would also be possible to form the shell body in the region of this underside horizontal or arcuate.

The upper side 4k is provided on the inside of the trough element 4j of the inner shell 4a at least in partial areas for venting a concrete material to be filled into the shell body with a sloping or arched course. As a result, any ascending air bubbles present in the liquid concrete are led away from the area of the upper side 4k which is important for the transmission of force and can be removed, for example. collect side of the important for power transmission area of the top 4k in trough-like recesses 4n where they have no negative impact on the operation of the device.

• Der Bewehrungsstab 7 ist hierbei mit zwei parallel zueinander angeordneten, sich in Horizontalrichtung erstreckenden Schenkeln 7a, 7a in hülsenartige Aufnahmen 4d, 4e der Innenschale 4a des Schalkörpers 4 eingesteckt und so gegenüber dem Schalkörper 4 lagefixiert. Von diesen beiden Aufnahmen 4d, 4e verläuft der Bewehrungsstab 7 mit seinen beiden Schenkeln 7a, 7a parallel und spiegelbildlich horizontal in das Gebäudeteil A hinein, ist dann nach einem etwa 120 mm langem Verlauf in zwei parallelen und spiegelbildlichen Bereichen 7c, 7c in das Gebäudeteil A hinein halbkreisförmig vertikal nach unten umgebogen, läuft dann beim dargestellten Ausführungsbeispiel über zwei parallele und spiegelbildliche Schenkel 7b, 7b in einem Abstand von ca. 30 mm parallel zum beschriebenen oberen Verlauf der Schenkel 7a, 7a in Horizontalrichtung zurück in Richtung des Schalkörpers und taucht horizontal in den Schalkörper hinein und ist dort wiederum in einem Bereich 7d halbkreisförmig umgebogen, wo sich beide Schenkel 7b, 7b treffen.

So that the aforementioned console-like bearing projection 6 provides optimal power transmission in the adjacent building part A, the shell body is provided with a reinforcing element 7, which consists of a multiply bent reinforcing rod of ribbed structural steel and its course mainly from the Figures 2 . 4a, 4b, 4c . 6a, 6b and 6c it is apparent:

• The reinforcing rod 7 is in this case with two mutually parallel, extending in the horizontal direction legs 7a, 7a inserted into sleeve-like receptacles 4d, 4e of the inner shell 4a of the scarf body 4 and fixed in position relative to the shell body 4. Of these two recordings 4d, 4e of the reinforcing rod 7 runs with its two legs 7a, 7a parallel and mirror image horizontally in the building part A inside, is then after about 120 mm long course in two parallel and mirror image areas 7c, 7c in the building part A. bent in a semicircular vertically downwards, then runs in the illustrated embodiment via two parallel and mirror-image legs 7b, 7b at a distance of about 30 mm parallel to the described upper course of the legs 7a, 7a in the horizontal direction back towards the shell and dives horizontally the scarf body into it and there again in a region 7d is bent semicircular, where meet both legs 7b, 7b.

The reinforcing rod 7 is in its immersed in the shell body semicircular horizontally bent portion 7 d spaced from the inner shell 4 a of the shell body 4 that it has at least a distance of the order of about 15 mm from the inner shell, so as to provide sufficient all-round concrete cover and to ensure power transmission. In order to fix this position permanently and securely in transport, the inner shell 4a has a holding web 4f in its region projecting furthest in the direction of the building part B into which the horizontally bent section 7d of the reinforcing rod 7 can be clamped. This jetty is mainly from the FIGS. 4a, 4b, 4c as well as the Figures 6a, 6b, 6c . 7, 8 and 9 seen.

Now, the device 1 according to the invention in the in FIG. 1 illustrated application case installed in the parting line C, so the reinforcing rod 7 ensures anchoring of the component 1 in the building part A and for a corresponding sufficient power transmission of the console-like support projection 6 in the adjacent building part A. On the other hand, the outer shell 4b provides mainly in Area of the top or ceiling surface 4c for a particular vertically extending pressure force introduction of the building part B, so that the insulating element 5, which is arranged between the outer shell 4b and inner shell 4a in the region of the ceiling surface 4c, the power transmission between the building part B and building part A so available ensures that it is soundproofed due to the insulation material.

For this purpose, the insulating material, for example, made of high-quality closed-cell polyurethane (PUR), while the inner and outer shell of the scarf body, the holding web and the receiving sleeves made of pressure-resistant material such as hard PVC can exist. Accordingly, the two outer walls of the partition plate 3 hard PVC exist. In addition, of course, other insulation materials or other pressure-stable plastics can be used.

The connection between the partition plate 3 and shell body 4 is achieved in the present example by snap-in connections, wherein the shell body hook-like locking lugs 4g in the region of the edge 4h of the inner shell 4a, which has the Outside wall 3a of the partition plate 3 in the region of the openings 3e engage behind and so set the entire shell body in the opening and so in the partition plate.

It is readily apparent that partition plate, shell body and reinforcing bar can be easily varied in terms of their dimensions or number and that due to the modular construction of the invention with a few components a very high variety of variants is possible.

At the in Figure 1 b illustrated installation example with turned to the head component 1, the staircase 9 is indeed as well as in FIG. 1a the supported part of the building, however, is in FIG. 1b the storage projection 6 associated with the flight of stairs, so that the staircase forms the second part of the building A. The shell body 4 extends into the first building part B, which in the case of Figure 1 b is formed by the landing 8, which in turn acts as the supporting part of the building.

In order that the bearing projection assigned to the supported building part A 6 can be supported in the supporting building part B, the shell body is installed quasi mirrored and ensures the mutual weight transfer from stair landing to flight over its bottom surface 4c ', like the ceiling surface 4c of the shell body 4 FIGS. 4a to 4c is trained. Accordingly, in the embodiment FIG. 1b the elastomeric bearing in the area of the bottom surface 4c 'provided.

The in the Figures 4a, 4b and 4c illustrated embodiments differ from each other only in terms of the storage projection: In FIG. 4a the storage advantage is not prefabricated, but is only made on site from in-situ concrete. In contrast, the variant shows off FIG. 4b a bearing projection 6 'made of concrete, which was prefabricated in the precast plant by concrete (especially high-strength or ultra-high-strength concrete or mortar) was poured into the trough element 4j of the inner shell 4a of the dummy body and thereby forms an end face 6'a in the built State in the vertical direction set back arranged in the shell body to place the in-situ concrete (from which the building part A is created on the construction site) place in the shell body to produce a mutual positive connection.

Figure 4c shows now an alternative course of a bearing projection 6 "made of concrete, which was also prefabricated in the precast plant by concrete (especially high-strength or ultra-high-strength concrete or mortar) was poured into the trough element 4j of the inner shell 4a of the dummy body is essential In this case, an end face 6 "a is formed, which in the installed state in the inclined direction with the lower portion of the front side further back into the shell body in order, in turn, the in-situ concrete (from which the building part A is created on the site) place in To provide Schalkörper for producing a mutual positive connection and to ensure but also by the inclined end face equal for improved ventilation of the in-situ concrete. Because any existing in-situ concrete air bubbles can thereby not collect in the shell body, but are transported away by the inclined course immediately from the insulating body.

In summary, the present invention has the significant advantage of being able to be adapted by simple changes in dimension and number of individual parts for different applications without this would lead to a complete overhaul of the device. Thus, the device according to the invention can be used wherever a sound-insulated pressure force transmission between two horizontally adjacent parts of the building is needed.
