Assembly type steel hanging box structure

Abstract

The invention discloses an assembly type steel hanging box structure, and relates to the field of civil engineering equipment. The steel hanging box structure comprises a bottom plate, a wall body andan assembly type truss structure, the steel hanging box structure is composed of three main body structures, namely the wall body, the bottom plate and the assembly type truss structure, all the three main body structures are connected into a whole through detachable connecting pieces such as anchor bolts, bolts, pin shafts and nuts, assembly type connection of a whole hanging box is achieved, and the steel hanging box structure can be detached for turnover use after construction.

Description

technical field [0001] The invention relates to the field of civil engineering equipment, in particular to an assembled steel hanging box structure with simple structure and convenient assembly and maintenance. Background technique [0002] In the past, the suspension boxes of similar cross-sea bridges were mainly steel suspension boxes (such as Hangzhou Bay, Jintang, Nan'ao Bridge, etc.) and concrete suspension boxes (such as Donghai Bridge). Among them, steel suspension boxes have difficulty in removing the steel floor and pose a great safety risk , and there is a hidden danger of electrical conduction with the steel pipe pile; the concrete hanging box has problems such as heavy hoisting weight, one-time investment in the concrete wall, and high cost. [0003] Chinese patent publication number is that CN201891123U discloses a kind of concrete floor single-wall steel hanging box. It includes the bottom slab and several side slabs, which are assembled and bottomed on the st...

AI Technical Summary

Problems solved by technology

However, according to the instruction manual, it can be known that the bottom plate is spliced ​​by multiple symmetrical concrete slabs, the integrity is poor, the rigidity of the bottom plate also has certain defects, and the connection between the bottom plate and the steel hanging box is unstable, and there are still difficulties in assembly and dismantling
