Beam for supporting formwork panels

The innovation relates to a carrier for supporting shuttering panels, consisting of an upper flange and a distance from this held lower belt, said belts F ".nnenprof ile have thus z <st main axis of the beam cross-section are symmetrically arranged such that their webs facing each other , while the flanges of both belts from the webs /: strut in opposite directions and end in edge parts bent ^{outwards by about 1BO D.}

Such carriers are parts of a kit for making ^r i formwork.

From DT-AS 1 6ßk 271 such a girder directly supporting the formwork skin is known, in which the upper and lower chords are kept at a distance by means of struts arranged in a framework and connected to the chords by sleepers.

However, this carrier is relatively expensive to manufacture.

The task of the innovation is now to manufacture a carrier to simplify the type described at the beginning and preferably also to reduce the cost of materials and the dead weight, without reducing its load-bearing capacity.

Solution to this task is characterized by nsuerunys in that the upper and lower chords meet the surfaces of one Form U-profile beam.

For this purpose, aich identifies a preferred and inventive one Embodiment in that the upper and lower belts alB A longitudinal web of sheet metal bent parts are formed.

Due to these measures, around 50 % of the previously required, wage-intensive shooting work are eliminated compared to the known embodiment. In addition, while maintaining the load-bearing capacity, the dead weight and thus also the cost of materials could be reduced.

An advantageous, the load-bearing capacity, or The design of the prescribed design continues to reduce the dead weight The object consists in the fact that in the channel of the U-profile girder arranged in the longitudinal direction at a distance from each other, the straps are arranged in addition supporting crossbars.

In addition, aich identifies an advantageous feature of the above Object in that in the longitudinal web spaced-apart fastening eyelets are arranged.

This allows the carrier on pillars vein carriers of the Fasten the formwork support structure quickly and securely using simple mechanical engineering elements.

An exemplary embodiment of the innovation is shown in the drawing and is described in more detail below.

The drawing shows part of the carrier in perspective Depiction.

In this girder bind, the upper chord 1 and the lower chord 2 are formed by bending the longitudinal edges of a web 3 made of sheet steel. Both belts 1 + 2 have a channel profile. They are arranged in relation to the main axis U of the cross-section of the girder so that the channel webs 5, 5 'face each other, while the flanges 6,6 * of the channel webs 5,5' strive in opposite directions and in flange parts 7,7 * which are bent outwards by 160 end up.

In the carrier trough are distributed over the lungs of the wearer Queratege β inserted and welded to the support.

The transverse webs θ support the belts 1, 2 over their entire Width from.

Under certain circumstances, aa is particularly advantageous, the transverse webs θ to be arranged in pairs and parallel to one another, the distance between the transverse webs θ of a pair being approximately one Fifth of the beam height.

Recesses 3 are also provided in the gutter webs 5.5 * to reduce weight, among other things.

Furthermore, 3 fastening holes 1D are arranged in the longitudinal web.

Matching wooden strips 11 can still be used in the belt channels, as shown in the case of the lower belt 2, in order to use this, for Example with nails to attach formwork panels.

To secure the position of the wooden strips 11, fastening holes 12 are also arranged in the channel webs. In the case of large quantities, the carrier, with the exception of the crossbars B, can also be produced by rolling, optionally also by extrusion.

Claims (3)

1. Beam for supporting formwork panels, which consists of a top chord and an original belt held at a distance from it consists, wherein the belts have channel profiles and so to The main axis of the cross-section of the beam are arranged symmetrically so that the bars face each other while the Strut the flanges of both straps from the webs in opposite directions and bent them outwards by about 180 ° Edge parts end, characterized in that the upper and lower belt (1,2) the flanges of a one-piece Form U-profile beam. 2. Carrier according to claim 1, characterized in that the Dber- and lower chord (1,2) as bent on a longitudinal web (3) made of sheet metal Parts are formed. 3. TrSger according to claims 1 or 1 + 2, characterized in that that in the groove of the U-profile beam in the longitudinal direction with a distance mutually arranged, the straps (1, 2) additionally supporting transverse webs (B) are arranged. km carrier according to one or more of the preceding claims, characterized in that fastening holes (10) arranged at a distance from one another are arranged in the longitudinal web (3). t— ^ r ^L - '^ y " * - Κ loop Patent attorney
