Triangular supporting bracket of suspended cast bridge block 0

Abstract

The invention relates to engineering machinery, in particular to a triangular supporting bracket of a suspended cast bridge block 0. The triangular supporting bracket comprises at least one set of supporting frames, wherein the supporting frames comprise horizontal girders installed on bridge pier bodies and further comprise diagonal bracing beams, wherein the upper portions of the diagonal bracing beams are connected with the horizontal girders, the lower portions of the diagonal bracing beams are connected with reinforcing steel plates, the bottom faces of the reinforcing steel plates are connected with transverse beams, the lower portions of the transverse beams are connected with bolt rods, and the bolt rods are inserted into reserved holes in the bridge pier bodies. The fixing operation of the lower ends of the diagonal bracing beams can be completed only by inserting the bolt rods into the bolt rod reserved holes in the bridge pier bodies, the triangular supporting bracket is convenient to use, operation work types are few, cross operation and mutual interference are decreased, and labor intensity of workers is reduced. The triangular supporting bracket is low in installation technology difficulty, can be installed by adopting a common work type and does not need special workers, and manpower resource configuration is optimized. In conclusion, cost is effectively saved, efficiency is improved, and the triangular supporting bracket is safe and provides a guarantee.

Description

technical field [0001] The invention relates to engineering machinery, in particular to a supporting triangular bracket for No. 0 block of a cantilevered bridge. Background technique [0002] Block 0 is self-heavy and works at heights. Whether it can be completed safely depends on whether the strength, deformation and stability of the formwork of block 0 can meet the requirements for safe use, especially as a load-bearing bracket. Therefore, the reasonable selection of the No. 0 block support form is also the key to the success of the cantilever beam construction. [0003] The common supporting forms of No. 0 block support are: floor type, pier-body-consolidated corbel, hoop type support, etc. The floor type means that the support of the bracket is set on the ground surface or the bearing platform. This kind of scheme needs to deal with the foundation, and the requirements for the foundation are relatively strict. It must have sufficient bearing capacity, and the settle...

Problems solved by technology

This scheme is suitable for the beam section with small upper load. Since there are many factors affecting the friction force, when the friction force is insufficient, there will be great safety hazards.
