Description

Technical area

The present invention relates to a connection element for connecting a steel structural part with a steel structural part upstream steel outer part.

State of the art

When connecting upstream steel exterior parts to steel building parts, for example, when connecting a steel balcony to a steel ceiling construction, two aspects are in the foreground. On the one hand, the various forces that act on the upstream steel component, ie tensile, compressive and / or shear forces, must be safely and completely transferred to the building or the subsoil. On the other hand, good thermal insulation must be ensured, since in practice the upstream steel components are subjected to severe thermal stress. The upstream parts can act as thermal bridges and cause structural damage.

For a long time known steel connection elements therefore generally have connecting elements for transmitting power to a building part and a body made of insulating material, which causes the greatest possible thermal insulation of the upstream steel component.

The DE 3 005 571 B1 discloses, for example, a cantilevered connection element with an elongated, cuboid insulating body of thermally insulating material. The insulating body is interspersed with elongated, metal reinforcing elements which extend substantially transversely to the insulating body and which are designed to absorb tensile forces. In addition to these reinforcing elements For example, the cantilever connection element has transverse force bars of reinforcing steel and steel construction parts which act as pressure elements.

The DE 37 00 295 C2 describes a cantilever panel connection element with an insulation body, at least one tension element and at least one pressure element. Tension element and pressure element pass through the insulating body approximately perpendicular to the main plane and are connected to each other by at least one transverse element. The cross member may be cross-shaped and derives in this case occurring in both directions transverse forces particularly well.

From the DE 101 30 866 A1 is a device for thermal insulation between a building and a projecting outer part known. The component has an insulating body with both sides arranged plate-like fastening devices and tensile, compressive and optionally transverse force elements. The insulating body including its plate-like fastening devices is divided into an upper part and a lower part, so that the plate-like fastening devices of the upper part are connected to the tension members and the plate-like fastening devices of the lower part with the pressure elements. In addition to the pressure bars, stiffeners in the vertical direction and stiffeners in the horizontal direction are integrated in the lower part. Both stiffeners are formed by two intersecting, mirror image arranged rods and serve to absorb lateral forces. A disadvantage of the device of DE 101 30 866 A1 in particular, the fact that the insulating body between the plate-like fastening devices is very difficult to be introduced. The DE 101 30 866 A1 proposes in this connection to subsequently foam the intermediate space, if necessary only after installation on site. Such a procedure is extremely time-consuming and expensive and usually does not lead to the desired insulation values.

In the case of the connection of a reinforced concrete structural part with a steel outer part, which is located upstream of the reinforced concrete structural part, there is also the problem that in steel construction with smaller tolerances is used than in the Concrete construction is common. To overcome this problem, an adjustable mounting of the connecting element has been proposed ( DE 199 08 388 A1 ).

The company Schöck Bauelemente GmbH offers under the designation Isokorb type KS (www.schoeck.de/de/produktloesungen) a connecting element intended for the installation of a cantilevered steel balcony. It consists of at least one vertically aligned mounting plate on which four steel bars are provided in pairs projecting horizontally so that they protrude forward as a threaded pin for securing the cantilevered steel structure. In the direction of the structure, the steel bars are also available and are poured into the concrete floor. Two upper long steel bars take over the transmission of tensile forces and two lower shorter bars transfer pressure forces. The installation of the connection element before concreting the ceiling is very complex and inaccurate.

The Isokorb KST is intended for connecting protruding steel components to steel structures. This consists of a tensile modulus and a pressure module, wherein in the pressure module between the two pressure rods, a hollow steel profile is welded as a reinforcing element. A disadvantage of this solution is in particular the fact that the cavity present in the pressure module can not be filled with insulating material, since any insulating material present there would lose its functionality due to the temperatures during the welding process.

Despite the known from the prior art solutions for connections of cantilevered steel elements to steel structures, there is still a need for static well-loaded and thermally well insulating connection elements, especially for connections in steel construction.

Presentation of the invention

This is where the invention starts. It is intended to be a connecting element for connecting a steel structural part with a steel outer part of the steel structural part upstream be provided, which has a good static load capacity with good thermal insulation at the same time. This object is achieved by the connection element according to independent claim 1. Further advantageous aspects, details and embodiments of the invention will become apparent from the dependent claims, the description and the drawings.

The connecting element according to the invention for connecting a steel structural part with a steel outer part of the steel structural part has a rectangular profile having four wall sections, the rectangular profile having a front wall section adjacent to the upstream steel outer part in the installed state; Building part adjacent, substantially parallel to the front wall portion extending rear wall portion and two, substantially parallel to each other and substantially perpendicular to the front and the rear wall portion extending, lateral wall portions, wherein the wall portions delimit a rectangular profile interior of a rectangular profile outer space. The connecting element also has at least two pressure rods extending substantially perpendicular to the front and rear wall sections of the rectangular profile and penetrating the front and rear wall sections of the rectangular profile, the pressure bars being provided with at least two external thread sections adjacent to the rectangular profile at least in the area of the rectangular profile external space are. Finally, the connection element has at least four threaded nuts arranged in the rectangular profile outer space, wherein at least two threaded nuts are respectively screwed onto a pressure rod, one threaded nut adjacent to the front wall portion and one threaded nut adjacent to the rear wall portion.

The connecting element according to the invention is associated with the particular advantage that provided for the transmission of transverse forces occurring rectangular profile designed open top and bottom and therefore is accessible for the introduction of insulation material. This will significantly improve Thermal insulation achieved, especially in the case of objects with particularly high requirements for thermal insulation.

In addition, with large differences in the thermal expansion of the steel floor / ceiling construction or the cantilevered steel outer part, shear forces occur as horizontal constraining forces, which are advantageously almost completely absorbed by the rectangular profile. The rectangular profile can be minimally changed into a trapezoidal shape and thus allow the shear forces. Such a recording of shear forces is in the device of DE 101 30 866 A1 not possible. The provided there in the lower part stiffening in the horizontal direction in the form of two intersecting, mirror image arranged rods sets horizontal shear forces against a resistance not to be overcome. A deformation of the device of DE 101 30 866 A1 is thereby prevented and occurring shear forces are introduced directly into the ceiling of the building part. Such an introduction of shear forces in the ceiling is almost completely prevented by the connection element according to the invention.

The dimensioning of the rectangular profile is generally based on the static requirements of the specific application and can be calculated by the skilled person in a simple manner and adapted to the specific situation. Preferably, the width b of the rectangular profile (expansion of the front or rear wall portion in the installed state horizontal direction) between 100 mm and 250 mm, more preferably between 130 mm and 200 mm, particularly preferably between 150 mm and 170 mm. The depth t of the rectangular profile (expansion of the lateral wall sections in the installed state horizontal direction) is preferably between 50 mm and 125 mm, more preferably between 65 mm and 100 mm, particularly preferably between 75 mm and 85 mm. The height h of the rectangular profile (expansion of the front or rear wall section and the lateral wall sections in the installed state vertical direction) is preferably between 30 mm and 100 mm, more preferably between 45 mm and 85 mm, particularly preferably between 55 mm and 75 mm , The thickness d of the wall of the rectangular profile is preferably between 2 mm and 8 mm, more preferably between 3 mm and 7 mm, particularly preferably between 4 mm and 6 mm.

It should be noted at this point that the term "rectangular profile" does not mean a profile with a horizontal shape in the mathematical sense exactly rectangular shape. As can also be seen from the figures of the present application, the corners of the rectangular profile can be rounded, for example. The term "rectangular profile" also includes other slight deviations from a rectangular shape. As a special case of a rectangle, a square shape also falls under the term "rectangular profile".

The frictional connection of rectangular profile and pressure bars is ensured by the adjacent in the region of the rectangular profile outer space the rectangular profile provided external thread sections and the threaded nuts screwed thereon.

Preferably, the two pressure rods are substantially in a common plane, in particular substantially in a horizontal plane. The term "essentially in a common plane" is to be understood that the two pressure rods run except for production-related deviations in a common plane. Steel exterior parts such as balconies are usually mounted in a horizontal plane on the building. Particularly preferably, the plane in which the two pressure bars extend, in the vertical direction below the focal plane of the upstream steel outer part. In this case, a particularly effective transmission of the pressure forces on the structural part caused by the upstream steel outer part is possible.

According to a further preferred embodiment, exclusively pressure rods run in the rectangular profile interior. This embodiment of the connection element according to the present invention expresses that the rectangular profile provided for transmitting the occurring transverse forces completely absorbs and dissipates all occurring transverse forces. So there are no additional bracing or stiffening elements on or in the rectangular profile required.

According to a preferred embodiment, the pressure rods in the region of the rectangular profile interior are each equipped with an external thread section. At least four threaded nuts are particularly preferably provided in the rectangular profile interior, wherein in each case at least two threaded nuts arranged in the rectangular profile inner thread are screwed on, each having a threaded nut adjacent to the front wall section and one threaded nut adjacent to the rear wall section. This embodiment considerably simplifies the fixation of the rectangular profile on the pressure rods required within the rectangular profile interior. The otherwise required welding connection is completely eliminated.

It should be pointed out that the connecting element according to the invention can nevertheless be equipped with welding spots. In particular, the arranged in the rectangular profile interior threaded nuts for fixing the position can be firmly connected by at least one welding point with the respective pressure rod. In the case of provided in the rectangular profile slots may also be provided between the threaded nuts and the rectangular profile welds to ensure that the push rod runs in the middle of the respective slot. If shearing or forced forces then occur when installed, the spot weld between the nut and the rectangular profile is forcibly released so that the pressure rod can move in the slot.

According to a particularly preferred embodiment of the present invention, an insulating body is arranged in the rectangular profile interior. As already described, the connection element according to the invention is associated with the particular advantage that the rectangular profile provided for transmitting the occurring transverse forces is designed to be open at the top and bottom and therefore accessible for the introduction of insulating material. If the rectangular profile interior filled with insulating material, a significantly improved thermal insulation is achieved, which is an advantage, especially in the case of objects with particularly high demands on the thermal insulation of buildings with, for example, balconies.

Advantageously, between the two arranged in the rectangular profile outer space, the front wall portion adjacent threaded nuts and the front wall portion each arranged at least one, penetrated by a respective pressure rod washer. Particularly preferably, between the two arranged in the rectangular profile outer space, the rear wall portion adjacent threaded nuts and the rear wall portion each arranged at least one, penetrated by a respective pressure rod washer.

As an alternative to the washers, at least one cooperating pair of a conical socket and a spherical disk, which is penetrated by a respective pressure rod, can be arranged between the two threaded nuts arranged in the rectangular profile outer space, the front wall section adjacent to the front wall section. Particularly preferably, at least one cooperating pair of a conical socket and a spherical disk are arranged between the two arranged in the rectangular profile outer space, the rear wall portion adjacent threaded nuts and the rear wall portion, which is penetrated by a respective pressure rod. With the use of conical socket and spherical disc has the advantage that also asymmetrically acting on the pressure connection element forces are always transmitted over the entire surface of the respective wall section.

According to a particularly preferred embodiment of the present invention, two, in the installed state horizontally extending slots are provided in the front and the rear wall portion of the rectangular profile, wherein the pressure bars penetrate the front and the rear wall portion of the rectangular profile through two slots, each having a push rod each penetrates a slot in the front and a slot in the rear wall section. As already mentioned, with great differences in the thermal expansion of the steel floor / ceiling construction or of the cantilevered steel outer part, shear forces act as horizontal constraining forces, which are advantageously absorbed by the rectangular profile in an advantageous manner. The rectangular profile can be minimally changed into a trapezoidal shape and thus allow the shear forces. The Recording the shear forces is supported by the horizontally extending slots in an advantageous manner. The elongated holes penetrating pressure rods have due to the slots a certain freedom of movement in the horizontal direction, whereby the recording of the shear forces no resistance is opposed.

As already mentioned, large differences in the thermal expansion of the steel floor / ceiling construction or of the cantilevered steel outer part result in constraining forces which must be tolerated by the connection element. Due to the guidance of the pressure bars by the horizontally extending slots in the installed state ensures that the pressure rods can move in the horizontal direction and thus absorb different thermal expansion of steel outer part and structure. In this case, the elongated holes are very particularly preferably dimensioned so that their extent in the installed state of a vertical direction substantially corresponds to the diameter of the pressure rods. In the direction of the transverse forces occurring then no clearance between the rectangular profile and pressure bars is present, whereby the shear forces are transmitted securely and completely.

The pressure rods, rectangular profile and threaded nuts provided in the connecting element according to the invention are preferably all made of metal, for protection against corrosion and because of the lower thermal conductivity, in particular made of stainless, that is stainless steel.

The present invention also includes the various possible combinations of the individual preferred embodiments mentioned above. In all cases, the combination of the individual elements specified in more detail leads to a combination of the advantages associated with these individual elements, which leads to particularly well suited, statically high load-bearing and at the same time well-insulated connecting elements.

The present invention also includes an arrangement for connecting a steel structural part with a steel outer part upstream of the steel structural part having one of the above-described connecting elements and a Zuganschlusselement. The Zuganschlusselement has at least one, in the installed state of the upstream steel outer part adjacent front plate member and at least one in the installed state adjacent to the steel structure part, extending substantially parallel to the front plate member rear plate member. When installed, the front plate element and the rear plate element each have a first lateral edge, an upper edge adjoining the first lateral edge, a second lateral edge adjoining the upper edge and opposite the first lateral edge, and one adjoining the second lateral edge and the upper edge opposite lower edge. The plate members, a plane containing the first side edge of the front plate member and the first side edge of the rear plate member, and a plane containing the second side edge of the front plate member and the second side edge of the rear plate member define a traction member interior from a traction member outer space. The tension connection element also has at least two tension rods penetrating the front and rear plate elements substantially perpendicular to the front and rear plate elements, the tension rods being provided at least in the area of the Zuganschlusselementaußenraum the plate elements adjacent each with two male threaded portions. Finally, the Zuganschlusselement has at least four, arranged in the Zuganschlusselementaußenraum threaded nuts, each screwed to at least two threaded nuts are each screwed to a pull rod, each having a threaded nut adjacent to the front plate member and a respective threaded nut adjacent to the rear plate member.

With the arrangement according to the present invention, a complete element for the connection of a steel outer part is made available to a steel structure part through which all forces, ie tensile, compressive and shear forces transmitted safely and reliably to the steel structure part become. The advantages already described in connection with the connecting element according to the invention, namely that the rectangular profile provided for the transmission of the occurring transverse forces is designed to be open at the top and bottom and therefore is accessible for the introduction of insulating material, whereby a significantly improved thermal insulation is achieved, and that occur in large differences in the thermal expansion of the floor / ceiling plate or the cantilevered steel outer part constraining forces that are well received by the rectangular profile in an advantageous manner, also arise in connection with the arrangement according to the present invention.

The two tension rods preferably extend essentially in one plane, in particular substantially in a horizontal plane. The expression "substantially in one plane" means that the two tension rods extend in a plane except for production-related deviations. Particularly preferably, the plane in which the two tension rods extend, in the vertical direction above the focal plane of the upstream steel outer part. In this case, a particularly effective transmission of the tensile forces caused by the upstream steel outer part on the building part is possible.

The frictional connection of the Zuganschlusselement and Zugstäben is ensured by the in the region of the Zuganschlusselementaußenraums the Zuganschlusselement adjacent provided external thread sections and screwed thereon nuts.

Particularly preferably, the two tension rods extend substantially in a horizontal plane. Steel exterior parts such as balconies are usually mounted in a horizontal plane on the building. In this case, a particularly effective transmission of the forces occurring in the horizontally oriented plane of the upstream plate is possible by the also extending in a horizontal plane tie rods on the building part.

According to a preferred embodiment, the tension rods are provided in the region of the Zuganschlusselementinnenraums each having an outer threaded portion. At least four threaded nuts are particularly preferably provided in the Zuganschlusselementinnenraum, wherein in each case at least two, in the Zuganschlusselementinnenraum arranged threaded nuts are screwed on each of a tension rod, wherein in each case a threaded nut adjacent to the front plate member and a respective nut is disposed adjacent to the rear plate member. This embodiment considerably simplifies the fixation of the front and rear plate elements on the tension rods required within the Zuganschlusselementinnenraums.

According to a particularly preferred embodiment of the present invention, an insulating body is arranged in the Zuganschlusselementinnenraum. If the Zuganschlusselementinnenraum filled with insulating material, a significantly improved thermal insulation is achieved, which is an advantage, especially in the case of objects with particularly high demands on the thermal insulation with balconies, for example.

Advantageously, between the two arranged in the Zuganschlusselementaußenraum, the front plate member adjacent threaded nuts and the front plate member each arranged at least one, penetrated by a respective tie rod washer. Particularly preferably, between the two arranged in Zuganschlusselementaußenraum, the rear plate member adjacent threaded nuts and the rear plate member in each case at least one, penetrated by a respective tie rod washer is arranged.

As an alternative to the washers, at least one co-operating pair of a conical socket and a spherical disk, which is penetrated by a respective pull rod, can be arranged between the two threaded nuts adjacent to the front plate element and the front plate element in the Zuganschlusselementaußenraum. Particularly preferably, between the two arranged in Zuganschlusselementaußenraum, the rear plate member adjacent threaded nuts and the rear plate member each have at least one cooperating pair of a conical cup and a spherical disc, which is penetrated by a respective tie rod.

In general, the number of connection elements corresponds to the number of Zuganschlusselementen, but it can also deviate from it, so it can be used in a different number of connection elements and Zuganschlusselementen in a row. The dimensioning of the arrangement and thus the number of connection elements and Zuganschlusselementen generally depends on the static requirements of the specific application and can be calculated by the expert in a simple manner and adapted to the specific situation.
