Rectangular wind-resistant bracket

Abstract

The invention discloses a rectangular wind-resistant bracket, and belongs to the technical field of bridges. The rectangular wind-resistant bracket comprises an upper main beam, a lower main beam, two inclined struts, bracing steel plates and an anchor plate, wherein the upper main beam and the lower main beam are located on the upper portion and the lower portion of the bracket respectively, the two inclined struts are located between the upper main beam and the lower main beam and connected with the upper main beam and the lower main beam, the bracing steel plates are connected and fixed with the inclined struts, the upper main beam and the lower main beam, and the anchor plate is arranged on the ends of the same side of the upper main beam and the lower main beam; the upper main beam, the lower main beam and the inclined struts are formed by two steel channels in a buckled mode respectively, a gap is reserved on each buckled position, full-length welding in an up-and-down mode is carried out on each buckled position, and connecting batten plates arranged at equal intervals are used for welding and fixing the buckled positions; the upper main beam and the lower main beam are welded and fixed through the two inclined struts in an up-and-down crossed mode, the parallelogram bracing steel plates are adopted to weld and be connected with the upper main beam, the lower main beam and the inclined struts at four corners of the welding connecting position once again, and anchoring holes are formed in the anchor plate. The rectangular wind-resistant bracket is a novel bracket and has higher bearing capacity, stability and wind resistance.

Description

technical field [0001] The invention belongs to the technical field of bridges. Background technique [0002] The construction of prestressed concrete continuous beams generally adopts the erection of full-scale scaffolding or cantilever pouring through hanging baskets. When the bridge pier is high or the scaffolding cannot be erected under the bridge, the hanging basket cantilever pouring construction can only be used. The premise of the hanging basket construction is that the 0# section must be completed on the bridge pier, and the 0# section construction is generally by pre-embedding the embedded parts on the top of the pier, and the installation bracket bears the load of the cantilever part of the 0# section and provides construction work space. [0003] Generally, the commonly used bracket is triangular, the rigidity and stability are not very good, and the bearing capacity is low. [0004] At an altitude of about 100 meters in the mountainous area, the wind is stron...

AI Technical Summary

Problems solved by technology

[0004] At an altitude of about 100 meters in the mountainous area, the wind is strong. If ordinary triangular brackets are used, the construction and safety requirements cannot be met.
