Stay stretching bias-jointing force transmission beam

Abstract

The invention relates to a stretch-draw mitred force transferring cross beam for a guy cable, which comprises an upper top slab (1), a lower base (2), a central pipe (3) and stiffening ribs (4), wherein the upper top slab (1) and the lower base (2) are fixed on the upper side and the lower side of the central pipe (3) respectively; the stiffening ribs (4) comprise vertical stiffening ribs (41) and insequent-intersection stiffening ribs (42); the upper ends and the lower ends of the vertical stiffening ribs (41) and the insequent-intersection stiffening ribs (42) are connected with the top slab (1) and the lower base (2) respectively; the inner sides of the vertical stiffening ribs (41) and the insequent-intersection stiffening ribs (42) are fixed on the central pipe (3) respectively; the force transferring cross beam is obliquely divided into two symmetrical parts along the midline of one of the insequent-intersection stiffening ribs (42); and the two symmetrical parts are fixed together by fixing pieces (5). Therefore, the weight of the cross beam can be reduced, transverse tension in the stretch-draw process can be effectively overcome, and the safety in the construction process can be improved.

Description

technical field [0001] The invention belongs to a force-transmitting crossbeam device installed at a cable head for prestressed tensioning of cables such as steel wire bundle twisting, steel strand assembly or steel tie rods in civil engineering construction. Background technique [0002] In the prestressed steel structure, cable-membrane structure, and curtain wall cable-rod support structure of civil engineering, there are cables that need to be pre-tensioned. The cable can be in various forms such as semi-parallel twisting of high-strength steel strands, assembly of multiple steel strands, or steel rod rods. When applying pre-tension to the cable at home and abroad, it is necessary to clamp the force-transmitting beam at the shoulder of the cable head at the end of the cable. The shaft divides it into two parts. When the field tensioning device is installed, the two halves of the block are placed on the shoulder of the cable head and connected by bolts to form an integra...

Problems solved by technology

[0003] Technical problem: In order to overcome the shortcomings of the existing tensioning force transmission beam that is large in size and unfavorable to the tensioning device and connecting bolts, the present invention provides a cable tensioning force transmission beam that is placed under the pressure end surface of the tensioning jack. The stiffening ribs required for the force-transmitting beam and the cross ribs at the oblique joints are integrated, which not only reduces the volume of the tension-transmitting beam, but also effectively overcomes the lateral tension generated during the tensioning process, increasing the security
