Steel girder rod piece assembling movable and telescopic high-strength bolt screwing platform

Abstract

The invention relates to a construction device for bridge section girder high-strength bolt construction, in particular to a steel girder rod piece assembling movable and telescopic high-strength bolt screwing platform which is convenient to erect and high in construction efficiency. The steel girder rod piece assembling movable and telescopic high-strength bolt screwing platform comprises a steel pipe support. Road wheels are arranged on the bottom of the steel pipe support, two mutually vertical telescopic sliding platforms are arranged on the upper portion of the steel pipe support, and the two mutually vertical telescopic sliding platforms comprise second sliding platforms vertically arranged on the top portion of the steel pipe support and first sliding platforms horizontally arranged below the second sliding platforms. The steel girder rod piece assembling movable and telescopic high-strength bolt screwing platform can reduce construction time, is simple in operation method, not only is suitable for high-strength bolt screwing in steel truss girder rod piece assembling, but also can improve work efficiency of the high-strength bolt screwing.

Description

technical field [0001] The invention relates to construction equipment for high bolt construction of bridge segment beams, in particular to a high bolt screwing platform for assembling steel beams and rods with convenient erection and high construction efficiency. Background technique [0002] Because the high-strength bolt connection has the advantages of simple construction, good mechanical performance, removable, fatigue resistance, and no loosening under dynamic load, with the development of steel truss bridges at home and abroad, more and more high-strength bolts However, due to the large number of high-strength bolts in a gusset plate and the many joints of each member, this brings many problems to the construction of high-strength bolts. The construction of high-strength bolts requires a large enough space and a safe enough construction platform. The conventional use of hangers as the construction platform is not only cumbersome, but also inevitably brings synchronous...

Problems solved by technology

The construction of high-strength bolts requires a large enough space and a safe enough construction platform. The conventional use of hangers as the construction platform is not only cumbersome, but also inevitably brings synchronous progress with the progress of the steel truss construction stage. The problem

If a crane is used to hoist forward, construction resources and time will be occupied
