Description

The invention relates to a U-profile support a canopy, hall, grandstand, stairs or a scaffold or podium and the like with an outwardly open U-profile, the parallel to each other and to the median longitudinal plane of the U-profile and connected by a transverse wall supporting leg having, preferably at its free ends support edges for a support element, such as a roof, in particular a cassette roof or roof or a running and / or working surface element, in particular a scaffold floor or its Eingehgehilfsmittel, such as claws, and having a one piece with the U Profile connected connection part for fastening and support of the U-profile on an elongated support member, in particular on a top flange of a lattice girder or on a scaffolding tube.

From the DE 35 42 610 A1 is a fast-mounting hall roof with a cassette roof has become known in which the roof skin elements are placed on U-shaped top chords of in practice also called cassette carriers roof trusses and supported. These trusses have except the upper belts also lower belts, vertical bars and diagonal bars, which are dimensioned in conventional steel construction technology and welded together. The upper straps are designed as upwardly open U-profile bars whose U-legs form vertical legs and whose base or base is formed with horizontal webs, which are welded to the vertical bars and the diagonal bars of the roof trusses. In the longitudinal direction of the respective roof truss are at the bottom of the upper flange in the middle of the horizontal bar at certain intervals upwardly outstanding securing tabs welded. These are suitable for a securing opening for a wedge longer than the vertical leg of the upper flange, with the help of which the roof elements are clamped to the upper flange.

This design has proven itself in practice and allows for rapid assembly and disassembly and is suitable to cover large spans. However, a crane is needed in any case for the assembly. The comparatively heavy roof trusses with their U-profile bars are designed for special use in roof structures. At the securing tabs other fasteners, such. B. railing holder according to the DE 297 11 346 U1 or fall protection auxiliary devices according to the DE 20 2004 001 314 U1 be connected. However, the fastening positions available for this purpose are limited to the positions of the securing straps welded firmly to the U-profile bars of the upper straps of the roof trusses.

An alternative possibility for the construction of roof structures, for example, from DE 100 28 262 A1 known become, which concerns a roof construction. This roof construction is made using so-called lattice girders, as they have become known for series parts in scaffolding. This roof truss forming lattice girders have a tubular upper flange, a tubular lower flange and rising and falling pipe diagonals as well as approximately vertical to the upper flange and the lower flange tubular vertical rods. Attached to the upper chords of the lattice girders is in each case connected over the entire length of the respective roof truss running connection profile unit. This comprises a extending over the entire length of the lattice girder U-profile, are welded to the underside and perpendicular thereto tubular support struts, at the side facing away from the U-profile lower ends each have a joint pipe coupling is welded. With the aid of these articulated tube couplings, the connection profile unit can be detachably fastened to the upper straps of the lattice girders. In this construction, depending on the geometric design and arrangement of the pipe diagonals and / or the vertical bars of the lattice girder, situations may occur in which the pipe couplings collide with one or more of these pipe diagonals and / or vertical bars, so that then there is no fastening of the connection profile unit the lattice girder by means of the joint pipe coupling is possible. This results in an increased security risk. To fix the tarpaulin of the tarpaulin roof to the terminal profile unit, a square timber is embedded in its U-profile, the upper side flush with the upwardly facing ends of the vertical webs of the U-profile unit. The tarpaulin is stapled to the square timber with metal brackets and additionally secured by a down hat-shaped open cover profile, the in turn is fixed with a plank penetrating and screwed into the square timber screw. This type of attachment is relatively expensive.

Applicants' similarly designed terminal profile units have become known in practice for use with cassette roofs. To attach their roof elements are welded to the bottom of the U-profile of the connection profile unit upwardly outstanding securing tabs, as already above in connection with the DE 35 42 610 A1 described, so that in this respect the same disadvantages occur.

From the DE 31 07 416 A1 has become known a supporting structure for buildable and degradable roofs or halls, in which both vertical supports and as a roof rack I-profile carrier with double cross bar is used. The I-profile carrier consists of two spaced apart parallel webs, which are connected at their ends in each case with a transverse wall to form a box-shaped hollow profile. At the two ends of the webs, in each case an I-flange is provided, the flange parts of which, viewed from the longitudinal center plane of the carrier, extend outward perpendicular to the webs and extend along the edges of the webs. One of the transverse walls extends at a distance to the associated I-flange in the interior of the carrier, so that an outwardly open cavity for inserting a wooden plank is formed. The opposite transverse wall is designed to form a T-shaped groove. This is used to hold a hammer head of a hammer head screw, by means of which on the I-beam profile a provided with a slot component can be determined by the on the Hammer head bolt is screwed on a nut and tightened. In order not to be able to define components provided with slots on the I-beam profile, a rectangular clamping plate can also be provided, through the round hole of which the hammer head screw is pushed through. The installation of this comparatively heavy I-beam profile is not possible without a crane and attached to the separately handled and transported wooden plank roof elements can be removed only consuming.

Similar I-beam with double cross bar are, for example, from DE 30 45 389 C2 known. Other I-beam profiles, which relate to a scaffolding element with a replaceable supplementary piece are from the DE-OS 28 50 098 and the DE-OS 28 50 545 ,known. These I-beam profiles have at their flange-side ends in each case an outwardly open T-shaped groove in which a separately manageable U-shaped additional element can be used, for this purpose at its connecting the two U-legs web with a T-shaped, outwardly facing approach is provided. Such an additional element can be used to hook the claws of serving as walking or working surfaces planks or frame panels. Such additional elements must be handled, stored and transported separately.
