摘要

Grid carrier removal frame for the segments - and tunnel, which comprises a plurality of which are screwed together and is composed of segments, and the segments of three parallel in the cross section forming the corner points of a triangle chord bars (1, 2) which, by stiffening elements (3) by means of welding in the sections (t1, t2) are fixed spatially in relation to one another, each closed in itself constructed reinforcing element (3) two v - the form of legs and the legs of a both sides of the (3) by means of sheets (t1) are connected to one another, characterized in that the ends of the straight sections (t2) and the center line of each leg with the center line of the leg end adjacent to the boom member (2) lies in a plane and that at the ends of the segments u - bracket (4) to the chord bars (1, 2) are welded, wherein the u - bracket (4) of one end by a tab (5), which has bores are connected to one another.
