Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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°.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • an elastomer bearing formed thereby is placed on the profile plate and extends in the horizontal plane.
  • 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.
  • 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.
  • the formwork body should be made of hard, incompressible material.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the formwork body 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.
  • 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.
  • bracket-like bearing projection which preferably consists of reinforcement element and support element
  • 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.
  • 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.
  • 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.
  • 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.
  • an insulating layer e.g. in the form of a PE foam panel
  • 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.
  • 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.
  • An essential aspect of the present invention lies in the modular structure.
  • the component 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.
  • 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.
  • 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.

  • 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.
