Title: Girders with compressed double boom
Inventor: PHILIPPE VELUT
IPC: E04D3/362
Filed: 1990-09-10
Abstract: It is known to reinforce the upper boom of a parallel girder using steel flats or any other shape of profile. The present invention relates to parallel girders in which there is a risk of buckling of the upper part of the web. In order to prevent this, a pre-stressing will be applied, exerting a traction on the critical zone by bearing on a first profile, while a second profile, which will be fixed only after the pre-stressing, will constitute the upper boom of the girder. With webs made of thin sheet steel, the transmission of the stresses can be achieved by simple friction, by clamping 2 profiles on one another and trapping the metal sheet, and at the same it will thus be possible to impose the shape of the sheet metal constituting the web, by imposing the direction of the initial tangent of the profile in the case of use of multiple girders they will be joined by a triangulation in the gaps and it will be possible for them to be assembled in advance.
