Description

The invention relates to a component for installation in separating joints of buildings, in particular in the area of balconies, loggias or arcades, for the sound-insulating, force-transmitting connection of adjacent parts of the building on both sides, with the features of the preamble of claim 1.

For soundproofed power transmission in the area of joints in particular on stair protests is, for example, from the EP-A 2626479 a structural element is known which, by dividing it into a separating plate on the one hand and one or more formwork bodies on the other hand, enables a modular structure which entails a separation of functions: the separating plate only has to ensure a sound-insulated spacing between the two adjacent parts of the building, whereas the power transmission alone is responsible for the Switching bodies are responsible, which are installed in corresponding openings in the partition plate and set there. The formwork body does not ensure the transmission of forces alone, but uses reinforcement elements for this purpose, which traverse the separating plate in the area of openings, with the reinforcement elements being inclined relative to the horizontal in order to absorb the forces occurring during the transmission of forces between the two parts of the building, based on the model of a conventional shear force bar can be transferred. Such components for impact sound insulation have now proven themselves, which is why there is a need to supply these other applications.

DE 20 2009 018 734 U1 discloses a connection element for connecting two parts of a building in earthquake zones, an insulating body made of thermally insulating material and at least one connection element transmitting the forces being arranged between the parts of the building. The connection element consists of a stiffening plate, which is arranged in the area of the insulating body and is firmly connected to two reinforcing rods. Stiffening plate, rebars and insulator are both to the horizontal and to Vertically arranged at an angle of 1° to 89°. It is an element optimized for earthquake stress, which is not suitable for sound insulation, as it does not acoustically decouple two parts of the building A and B, but creates an "acoustic short circuit".

EP-A 1889980 discloses a thermally insulating component for use in joints, in particular between a building ceiling and a balcony floor slab, with an insulating body through which reinforcement elements are passed transversely to the joint. The component shown is not suitable as an acoustically effective insulation element, since the building parts A and B to be decoupled are directly connected with (reinforcing) steel.

Proceeding from this, the present invention is based on the object of further developing a component for installation in separating joints of buildings according to the preamble of claim 1 and adapting it to further requirements in order to be able to make the advantageous impact sound insulation properties available to other components as well.

This object is achieved according to the invention by a component for installation in particular in a vertical plane extending separating joints of buildings with the features of claim 1.

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

According to the invention, the construction element for installation in separating joints of buildings is characterized in that the first reinforcement element is also designed as a shear force element in that it is arranged in the area of the separating plate inclined to a vertical plane EV _{perpendicular} to the separating plate. In this way, the horizontal rigidity of the component can advantageously be increased and the component can therefore be used wherever shear forces have to be transmitted in the horizontal direction, namely in particular parallel to the plane of the separating plate and possibly also perpendicular thereto.

Especially when using an insulating body for thermal insulation and an associated significantly increased thickness of the separating plate or a composite element made of separating plate and thermal insulation material, it is advantageous that, according to the invention, a second reinforcement element is additionally provided, which, starting from the second of the two parts of the building, passes through the separating plate protrudes in the horizontal direction into the formwork body and interacts there with the supporting element for the insulating element.

In order to further promote the aforementioned absorption and transmission of shear stresses, the support element and the insulating element on the one hand and/or the formwork body and the insulating element on the other hand are positively connected in the horizontal effective direction, as a result of which they absorb or reduce shear stresses in the horizontal direction both perpendicularly and parallel to the plane of the partition plate. can pass on. Normally, such a form-fitting connection is produced in that the supporting element or the shell body laterally embraces the insulating element and/or is supported on it, the insulating element is thus chambered by the supporting element and/or the shell body, so that movements of the insulating element are in the horizontal direction be passed on to the support element and/or the formwork body and vice versa.

Due to this additional possibility for the planned absorption of stresses, the construction element according to the invention can be installed in the area of balconies, loggias or drain passages, which regularly have to be soundproofed for impact sound insulation.

Especially in these mentioned areas of use, namely in balconies, loggias or arcades, there is a particular advantage in that the partition panel, which itself consists at least partially of soundproofing material and/or has soundproofing material to ensure the desired impact sound insulation, also consists at least partially of thermal insulation material and/or has an insulating body for thermal insulation that extends at least partially along the parting line. In this case, the separating plate together with the thermal insulation material forms a composite insulating element, which has an increased material thickness in the horizontal direction compared to the separating plate thickness. Especially with the increased compared to the partition plate thickness material thickness of the composite insulation element, the properties of the first reinforcement element can be really exploited: Because if the first reinforcement element is also arranged in the area of the insulating body inclined to the separating plate and inclined to the horizontal plane perpendicular to the separating plate as well as inclined to the vertical plane perpendicular to the separating plate, it runs through the insulating body and the separating plate in the inclined manner described and can thus also provide the desired lateral force transmission on the one hand and shear force transmission on the other hand in the area of the composite insulating element.

As a result, the first reinforcement element forms a vertically deflecting shear and shear force transmission element. The vertical deflection results from the fact that the structural element is expediently used in the case of supported or elevated building parts, ie additional means for absorbing the weight force, such as in particular supports, stands or traverses, are provided. The present component is not primarily used to absorb the weight forces of these parts of the building or moments acting as a result in the vertical plane, but smaller weight forces inevitably occur in the vertical direction in the area of the component, which the first reinforcement element has to absorb, which leads to the described vertical deflection, which is usually on the order of a few millimeters and is preferably less than 10 mm and in particular 4-8 mm.

Further advantageous effects result from the fact that the first reinforcement element consists of a reinforcement rod and is loop-shaped at least in some areas with two inclined loop legs, which are at least partially horizontally spaced from one another in the area of the separating plate and in particular with opposite inclinations relative to the vertical plane perpendicular to the separating plate E _V run. Such a symmetrical structure results in a substantially equal horizontal rigidity in the opposite horizontal directions. The two inclined loop legs running next to one another in the area of the shell body are expediently connected to one another again via a common loop base running essentially in a horizontal plane, with the first reinforcement element enclosing the support element with this loop base. This allows the first reinforcement element anchor on the supporting element and thus on the first part of the building and establish the desired connection between the first part of the building and the second part of the building.

As is already known in the state of the art, the rod material allows an ideal adaptation to the static tasks of force transmission to be achieved with a comparatively thin cross section of the reinforcement element. The material of the reinforcement element, in particular the reinforcement rod, is primarily metal and in particular stainless steel, which can be ribbed in the form of so-called reinforcing steel and thereby transmits the tensile force to the material of the second part of the building via the ribbing, or which can also be smooth-walled and is then anchored in the second part of the building via, for example, hook-shaped bends or terminal anchor heads.

For the desired lateral force transmission, the inclination of the first reinforcement element relative to the horizontal plane should be between 20° and 60° and preferably between 20° and 50°, while for the desired shear force transmission the inclination of the first reinforcement element relative to the vertical plane should be between 10° and 30° and preferably should be between 10° and 20°. This makes it possible to transmit the forces occurring in the force-transmitting connection between the two parts of the building according to the model of a conventional shear force element, with the reinforcement element - like a shear force element - generally only being subjected to tensile stress in its inclined course.

A major advantage of the inclined course of the reinforcement element is that the insulating element can be arranged in the first part of the building in such a way that the greatest possible height of the first part of the building is available in the overlapping area above - or, depending on the installation, below - the insulating element. This enables a significantly larger concrete cover, which can be used to optimize the introduction and dissipation of forces.

The second reinforcement element provided according to the invention can be designed as a compressive force element in that it is perpendicular to the separating plate extends in the horizontal direction and/or that it consists of a reinforcing bar and/or that it traverses the separating plate in the area of the openings or a further opening. The second reinforcement element is sensibly connected to the load-bearing element on the face side in a form-fitting, force-fitting or material-locking manner for stable compressive force transmission and has a terminal pressure plate on the opposite side, i.e. in the area of the second part of the building, which extends parallel to the parting plane and thus for improved anchoring of the second reinforcement element in the second part of the building. Advantageously, the contact area of the first reinforcement element on the support element and the connection area between the second reinforcement element and the support element are at least essentially at the same height, i.e. the same horizontal section, with the first reinforcement element reaching behind the support element with its loop base and thus the associated contact area being in the connection area of the second reinforcement element opposite to the support element. As a result, the first reinforcement element, which is subjected to tension, and the second reinforcement element, which is subjected to compression, stabilize each other in the area of the support element, in that the additional second reinforcement element counteracts the forces transmitted from the first reinforcement element to the support element.

It is essential for the sound decoupling provided by the building element that the reinforcement element traverses the opening in the partition plate, but does not extend into the adjoining second part of the building (i.e. not into the material of the second part of the building), but extends to the area of the Scarf body limited. An overlapping of the two adjoining parts of the building is only created in the area of the formwork body, but this is sufficient—with the appropriate dimensioning and number of formwork bodies—to ensure the required power transmission.

The formwork body with the associated first reinforcement element on the one hand and the separating plate on the other hand can easily be adapted to one another in terms of position, size, etc. For example, with one and the same partition plate, which only has to be based on the corresponding height of the adjacent parts of the building, large forces can be transmitted by installing correspondingly large dimensioned shells or a correspondingly large number of shells as well as the transmission of only small forces, which can then be worked with few or relatively small-sized shells and first reinforcement elements. The only adjustment to the separating plate must be to adjust the opening in terms of size and position to the installation and the number and dimensions of the formwork to be connected.

It is also important that the first reinforcement element has a support element for the insulating element and, together with the support element, forms a bracket-like bearing projection for the second of the two building parts and that this second building part extends into the shell body by means of the bearing projection and thus into the first building part for soundproofing , Power-transmitting connection of the two parts of the building protrudes. Thus, the bracket-like bearing projection, which is assigned to 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 transmission of force, without reinforcement rods extending from the first part of the building into the material of the second part of the building must and also without the overlap having to be provided by a particularly complicated design of the partition plate.

Thus, the support element can consist of a profile plate, which supports the insulating element at least indirectly and/or is supported on it, the support element in turn being held or supported by the first reinforcement element. If the reinforcement element is designed in the form of a rod and is bent in the form of a loop, it can, for example, rest on its bent area.

In the contact area between the support element and in particular the rod-shaped first reinforcement element, recesses or in particular bends can provide a contact surface on which the first reinforcement element can be supported on the support element—or vice versa—in the horizontal direction. As a result, the horizontal components resulting from the vertical load and the introduction of force via the inclined first reinforcing bar can be transferred via the supporting element into the connected second part of the building.

As for the load-bearing element, or in particular the profiled plate, first of all its main function must be taken into account: it must ensure the transmission of forces between the rest of the reinforcing element and the insulating element. The support element or the profile plate is expediently designed to be flat with a substantially horizontal support surface for the insulating element. It extends essentially in the horizontal direction and can be flat, for example cuboid, or advantageously has a vertical cross-section that is angled in some areas, in particular U-shaped, with two U-legs and a U-base, with the U-leg lying between the two U-legs U-base extending in the horizontal direction carries the insulating element. The two U-legs can take on additional functions such as securing the position of the insulating element or fixing the position of the support element on the partition plate.

Above all, however, if the support element extends out of the formwork body into the second part of the building, passing through the partition plate or the opening provided therein (or is connected to the second part of the building in a different, indirect or direct manner), the support element and in particular whose terminal U-legs are supported between the supporting element and the second part of the building, through which any horizontal force components that occur can be transmitted as compressive forces. This means that even if the reinforcement element can or should only serve to transmit shear forces, any horizontal components resulting from the vertical load can be absorbed and passed on via the additional support element and can thus be kept away from the reinforcement element, in particular rod-shaped. It is important that the supporting element is of course also sound-decoupled from the first part of the building and is thus also insulated against impact sound in the area in which the said terminal U-leg rests on the second part of the building.

The insulating element can be mat-like or plate-like in the known manner and in particular can consist at least partially of an elastomer. In the aforementioned case of the support element, an elastomer bearing formed thereby is placed on the profile plate and extends in the horizontal plane.

On the side of the insulating element opposite the supporting element there is a contact surface of the insulating element, which forms a force introduction/discharge area and in which the forces are transmitted as compressive force between the first part of the building and the insulating body. The insulating element in the area of the contact surface can either be acted upon directly by the material of the first part of the building, ie in particular by concrete, or with the interposition of the formwork body. This means that the formwork body can either have a recess in the area of which the contact surface of the insulating element is arranged in order to come into direct contact with the material of the first part of the building; or the formwork body can cover the insulating element in the area of the contact surface and directly pass on the forces occurring there between the first part of the building and the insulating element. For this purpose, the formwork body should be made of hard, incompressible material.

In this context, it is particularly advantageous if the contact surface of the insulating element interacts with a distribution element which consists in particular of pressure-resistant and/or high-strength material such as UHPC in particular and thus ensures improved force transmission between the insulating element and the material of the first part of the building. In this case, the distribution element ensures that force is introduced or transmitted evenly, without the quality of the material of the first part of the building in the area of contact with the formwork body having any significant impact on the transmission of force. If the distribution element were not provided in this area, defects in the contact area on the formwork body or on the insulating element could cause an uneven load on the insulating element and thus impair the insulating effect. However, this can be safely ruled out by the distributor element. Even if the formwork body is arranged between the distribution element and the material of the first part of the building, it usually consists of pressure-resistant, thin-walled material that does not impair the desired power transmission.

The trough-shaped formwork body is designed to be open on one side in the direction of the second part of the building, in order to accommodate the first reinforcement element and the supporting element. It separates the first and second parts of the building from each other by a closed trough-shaped surface. In a particularly preferred embodiment, the formwork body is only on the part facing the first part of the building External surface treated with concrete. The interior of the formwork body and thus also its inner surface are shielded from the material of the second part of the building by the separating plate and remain free from the material of the second part of the building, ie in particular from concrete. In this case, this interior advantageously serves to accommodate only the bracket-like bearing projection, ie the first reinforcement element and the support element, and in particular also the insulating element. As a result, the contact areas between the bearing projection and the shell body are reduced to the comparatively small-area area of the insulating element, which is optimized with regard to sound-insulating mutual contact. This leads to an optimal, sound-insulated, force-transmitting connection to the structural element designed in this way in adjacent parts of the building.

The vertical dividing plane between the two parts of the building is provided with these trough-shaped indentations, which extend into the first part of the building, but without affecting the course and, above all, the shape of the remaining dividing plane in the area of the dividing plate.

In the region of its cavity, the formwork body should be arranged at a distance from the first reinforcement element and the supporting element on the side opposite the insulating element, in order to avoid impairment or disruption of the impact sound insulation through mutual contact.

It is also particularly advantageous if the trough-shaped formwork body consists of at least one arched trough element for accommodating the reinforcement element, which extends essentially in the horizontal direction, the support element and the insulating element, as well as an edge, which extends essentially in the partition plate plane, which is vertical in particular, and if the formwork body is attached in the area of the edge to the separating plate in the area or preferably slightly outside of its openings, in order to ensure liquid concrete-tight contact with the separating plate. The attachment can be done by clamping, locking or clip connections, but also by materially bonded adhesive or welded connections.

The trough shape must of course be dimensioned so large that the bracket-like bearing projection (which preferably consists of reinforcement element and support element) surrounded by the formwork body is strong enough to ensure the required power transmission. There are certainly a large number of shell shapes that can be considered, which are generally described as "trough-shaped" in the present case, which is primarily intended to mean that the parting plane in the area of the shell body is bulbous, arched, deepened or in some other way to create a space, in particular a cavity for the reinforcement element is formed and thus deviates from the otherwise flat profile of the partition plate. The wording "trough shape" used here is not intended to define the exact shape of the room; Rather, cuboids with flat side surfaces are just as possible, as are bodies deviating from this with curved or inclined side surfaces, etc., as well as wedges, cylinders, trapezoids, etc. All common and thus corresponding to the "trough shape", is the design open on one side, which ensures that the shell body is connected to the separating plate in the area of an opening adapted to the shell body and that the parting plane in the region of the shell body is at least partially relocated from the plane of the separating plate to the plane of the shell body, ie the plane of the shell body.

As described above, the insulating element can - depending on the application - be arranged in the area of the top and/or bottom surface of the formwork body, namely at least there where the force transmission takes place.

Instead of a single-shell shell, a multi-shell structure is also possible or the combination of a flat shell with an insulating layer (e.g. in the form of a PE foam panel), whereby these two components can be connected to one another over the entire surface, in particular glued.

The same applies to the partition plate, which can also be made up of a flat first wall and an insulating layer attached to it (e.g. in the form of a PE foam panel) or also of two flat first walls and an insulating layer arranged between them, these components in turn covering the entire surface connected to each other, in particular can be glued.

Regarding the attachment of the reinforcement element to the material of the partition plate, the openings can be adapted to the shape of the reinforcement element in the crossing area, for example, so that direct mutual contact ensures the necessary fixing of the reinforcement elements on the partition plate. If the first reinforcement element runs inclined in the area of the separating plate, there is also an additional possibility of support in a horizontal direction.

In addition, of course, there are also other fixing options, e.g. by molding plastic holding elements onto the separating plate, into which the reinforcement element can be inserted, clipped or fixed in some other way. The type of fixing should be designed in such a way that the reinforcement element can actually be securely fixed in position relative to the separating plate in order not to change the specified position of the reinforcement element within the formwork body even if loads occur during transport, assembly on the construction site or when it is impacted by in-situ concrete affect. Against this background, too, it makes sense to additionally fix the reinforcement element in the area inside the formwork body by means of a plastic web at another point on the separating plate.

An essential aspect of the present invention lies in the modular structure. Against this background, it is particularly expedient for the component to have a plurality of openings provided in the separating plate, a plurality of shell bodies arranged next to one another, particularly in the region of the openings, and a plurality of first reinforcement elements that extend into the corresponding shell bodies. This makes it possible to adapt the component to the respective application or load case and to utilize the desired modular structure according to the invention.

It should also be pointed out that the present invention can be used not only for using the construction element according to the invention on the construction site and creating the first and second building part from in-situ concrete, but that the present invention can also be used particularly advantageously and effectively in the precast plant.

Finally, the component can be provided with a fire protection material in a manner known per se, particularly in the area of the separating plate, e.g. with a strip of intumescent material which is arranged in a depression in the separating plate and/or in terminal end caps for lateral, i.e. terminal sealing of the separating plate.

In figure 1 a component D for installation in buildings is shown in a sectional side view, which is arranged between two adjacent building parts A, B in the form of an arcade 9 as the first building part B and a building wall 8 as the second building part A. Between the second building part A and the first building part B there is a separating gap C, which extends vertically over the entire height of the thinner of the two building parts, in this case building part A, and not only represents a construction joint, but also provides impact sound insulation between the adjacent components must worry.

In the area of the dividing line C between the two parts of the building A, B, a flat dividing plate 1 is arranged, which extends over the entire height of the dividing line C and--as is particularly the case Figure 2b can be seen - has a horizontal length in the order of, for example, 1 meter.

The partition plate 1 is - as in particular Figure 2a can be seen - from two relatively pressure-resistant outer walls 1a, 1b, which are only connected to one another by a few horizontal intermediate webs and otherwise maintain a mutual distance of the order of approx. 10 mm, in order to thereby keep the two adjacent building parts A and B at a distance from each other hold and prevent a corresponding mutual contact and thus vibration and sound transmission. The outer walls 1a, 1b have several horizontally running ribs or webs that protrude a few millimeters and ensure a certain anchoring of the separating plate in the adjacent concrete of part B of the building. The outer walls 1a, 1b with the intermediate webs are self-supporting and pressure-resistant enough to withstand the forces of the liquid concrete material when the building parts are made of in-situ concrete or are prefabricated from concrete in the precast concrete plant and to keep both parts of the building permanently at a distance even after the concrete material has hardened.

To improve the sound insulation, an insulation board 1c made of polyethylene is arranged between the two outer walls 1a, 1b, the three elements being fixed to one another in a sandwich construction, e.g. glued over the entire surface.

The partition plate 1 has a plurality of openings 1d arranged next to one another and one above the other--see in particular FIG Figure 3b , attached to the trough-shaped shell body 6 (each in the same direction) or inserted through the reinforcement elements 3, 4 - see in particular Figure 2a . Each formwork body is fixed flat and liquid-tight to the outer wall 1b of the partition plate 1 with its upper edge. The scarf body 6 is - as in particular from the Figures 5a, 5b, 6a and 6b can be seen - designed trough-shaped, in particular bulbous or curved and forms a cavity 6d, which is largely limited or enclosed by the shell body. The hollow space 6d serves to accommodate in particular a first reinforcement element 3, while the outside of the formwork body is acted upon by the concrete of part B of the building.

As above all from the figures 1 and 5a, 5b As can be seen in the vertical section, an insulating element 5 in the form of a plate-shaped elastomer bearing is arranged approximately in relation to its height in the central region of the formwork body, which ensures the soundproofed transmission of force between building part B and building part A. The elastomeric bearing 5 rests flat with its upper contact surface 4a from below on a part of the reinforcement element, namely the supporting element 4 described in more detail below, whereas the elastomeric bearing 5 with its lower contact surface 5b acts flatly on a distribution element 7 from above. The distribution element 7 in turn adjoins the shell body 6 with its surface opposite the elastomer bearing or insulating element 5 . The exact outer shape of the distribution element 7 is in the Figures 8a, 8b and 8c recognizable, where you can also see the curved underside, over which the distribution element rests on the formwork body. Thus, the shell body 6, elastomeric bearing 5 and support element 4 rest against one another over the entire surface, as is particularly the case Figure 5a, 5b is evident.

the Figures 5a, 5b, 6a, 6b show the trough shape of the shell body 6, which in the illustrated embodiment is mainly due to the underside of the Shell body arrives, on which the distribution element 7 described rests and which is used to introduce force.

The rest of the shape of the trough is not primarily relevant for power transmission and soundproofing; care must only be taken to ensure that a spacing from other elements such as in particular reinforcement element 3 and/or support element 4 is maintained in order not to impair the impact sound insulation through mutual contact.

The shell body has two adapted to the course of the reinforcing bar 3 inclined legs 6a and two mainly from the Figures 5a and 5b visible folds 6b, between which the elastomer bearing 5 and the distribution element 7 are bordered in the horizontal direction and fixed in this way.

In the other areas of the formwork body is this - as in particular Figures 5a, 5b, 6a, 6b can be seen - approximately cuboid with substantially horizontal and vertical flat side surfaces and runs there at a distance from the first reinforcement element 3 and any elements otherwise arranged in the cavity 6d.

The shape, the course, the position and the orientation of the first reinforcement element 3 are in particular 3 , 4a, 4b and 4c evident. Each formwork body 6 is assigned a first reinforcement element 3, which consists of a metal reinforcement bar. The reinforcing bar is bent in the form of a loop in the area of the cavity 6d of the formwork body 6, so that two legs 3a, 3b of the reinforcing bar 3 extend out of the formwork body 6 in the direction of the second building part A, with a loop base 3c connecting the two legs being approximately horizontal in the formwork body 6 runs.

The two loop legs 3a, 3b are horizontally spaced from each other in the area of the partition plate 1 and extend with mutually opposite inclination by an angle β of about 14° relative to the perpendicular to the partition plate and in the figures 2b and 4b shown vertical plane E _V .

On the way into the second part of the building A, the two legs 3a, 3b each pass through the opening 1d in the separating element 1. Starting from the horizontal base 3c, while crossing the openings 1d and then in the area of the second part of the building A near the edge, the two legs 3a run , 3b inclined in a straight line at an angle α of about 30° to the figures 2a and 4c shown horizontal plane E _H , as is known from shear force reinforcement bars in components for thermal insulation. Only in a lower area of the second building part A do the two legs meet again, are bent together according to the angle α of about 30° and merge into a parallel horizontal section 3d and are thus anchored in the second building part A over a large binding length.

The reinforcing bar 3 lies in its inclined course 3a, 3b to edges of the openings and is also supported on the legs 6b of the formwork body 6, into the cavity 6d it protrudes.

According to an essential aspect of the invention, the reinforcement element has a support element 4 for the insulating element 5 . For this purpose, the reinforcing bar 3 carries a profile plate in the area of its base 3c, which forms the supporting element 4 and--as already mentioned above--on which the insulating element 5 rests. The profile plate extends essentially in the horizontal direction, is angled with its edges 4c in the vertical direction and thus forms a U-shaped vertical section with two vertical U-legs 4c and a horizontal U-base 4a, which rests on the plate-shaped insulating element 5. By means of the two U-legs 4c, the support element 4 enters into a form-fitting connection with the insulating element 5 in the horizontal effective direction.

Serving as a supporting element profile plate is particularly from the Figures 7a - 7d recognizable, which show the profile plate in different views, as well as from 3 , which also shows the first reinforcing bar 3 and its interaction with the supporting element.

In addition, the support element 4 has an elevation 4d on its upper front side facing the separating plate 1, which is surrounded by the first reinforcement element 3 by means of the two legs 3a, 3b and the loop base 3c is how this particular from the figures 2a and 3 is evident. For this purpose, the leg base 3c of the first reinforcement element 3 rests flat against a groove 4f that closes off the aforementioned elevation 4d and, due to the enlarged contact surface, ensures favorable force transmission between the first reinforcement element 3 and the supporting element 4.

Finally, in the area of said elevations 4d, the supporting element 4 has a central nose-like projection 4e on its upper side, which is used to connect a second reinforcement element 13, and which, in particular, is figures 2a and 3a is shown. This second reinforcement element 13 extends in the horizontal direction, consists of a bar material and assumes the function of a pressure element, which extends from the support element 4 through the partition plate 1 to the second part A of the building. While one end of the second reinforcement element 13 dips into the nose-like elevation 4d of the supporting element, it has a pressure plate 13a on its other end, which is arranged in the second building part A, in order to improve anchoring in the second building part A. The pressure plate 13a extends in a plane parallel to the separating plate 1 perpendicular to the direction in which the second reinforcement element 13 extends must meet excessively high requirements.

In order to leave space for the second reinforcement element 13 to pass through the separating plate 1, the openings 1d—as shown in particular in FIG Figure 3b can be seen - in each case on their upper edge central elevations 1f.

Finally, the partition panel 1 has, in addition to the soundproofing material 1d, an insulating body 1e made of thermal insulation material and extending along the outer wall 1a of the partition panel 1 and also intended to be placed in partition joints C together with the rest of the partition panel 1. The insulating body 1e lies flat against the outer wall 1a and is traversed by the first reinforcing bar 3 and the second reinforcing bar 13 . Since such insulating bodies for thermal insulation usually have a horizontal thickness of at least 80 mm, the free length, ie the length not supported by the two parts of the building, is the first and second reinforcement elements correspondingly large, which of course also increases the load due to the shear and transverse forces that occur.

If the component 1 according to the invention is now placed in the in figure 1 installed in the parting line C, the ribbed first reinforcement rod 3 ensures anchoring of the component 1 in the building part A and thus a correspondingly sufficient force transmission into the adjacent building part A. On the other side, the formwork body 6 ensures, above all, in the area the one for a compressive force introduction running in particular in the vertical direction of the building part B, so that the elastomer bearing 5, which is arranged between the shell body 6 or distribution element 7 and the supporting element 4, provides the force transmission between the building part B and the building part A in a sound-insulated manner. Due to the insulating body 1e additionally attached to the separating plate 1 in the parting line C and since the first reinforcement element 3 and the second reinforcement element 13 extend through the separating plate 1 with the attached insulating body 1e, the mentioned sound-insulated power transmission also takes place in a thermally insulated manner.

The insulating material consists, for example, of high-quality closed-cell polyurethane (PUR). As far as the two outer walls of the partition plate 1 are concerned, they can be made of pressure-resistant material such as hard PVC, whereas the insulating plate 1c arranged between the outer walls can be made of polyethylene (PE). In addition, other insulating materials or other pressure-resistant plastics can of course also be used.

It is not difficult to see that the partition plate, formwork body, insulating element and also the first and second reinforcement element and support element can easily be varied in terms of their dimensions or number and that due to the modular design according to the invention with few components, a very high number of variants is possible.

The first reinforcement element 3, the second reinforcement element 13 and the support element 4 together form a bracket-like bearing projection which extends into the interior of the formwork body 6, where it interacts with the insulating element 5 and the distribution element 7, which in operative connection stand with the first part of the building B and are acted upon directly or indirectly by its material, in particular concrete. In summary, the present invention offers the essential advantage of being able to be adapted to a wide variety of applications by simple modifications within the scope of protection of the appended claims with regard to dimensions and number of individual parts, without this having to lead to a complete revision of the component. Thus, the component according to the invention can be used wherever a noise-insulated transverse and shear force transmission is required between two horizontally adjacent parts of the building, which can have additional properties such as thermal insulation in particular.
