Steel bar truss plate end connecting joint structure and construction method thereof

Abstract

The invention relates to the field of construction of steel structure buildings, in particular to a steel bar truss plate end connecting joint structure and a construction method thereof. The steel bar truss plate end connecting joint structure comprises steel bar truss plates and steel structure beams; one side of each floor bearing plate is detachably connected with a steel bar truss, and supporting pieces are arranged on the other sides of the floor bearing plates at intervals and stretch out of the floor bearing plates; a steel bar truss plate is laid on one side of each steel structure beam; and supporting bars are welded to the ends of the steel bar trusses and welded to the steel structure beams, and the upper surfaces of the floor bearing plates and the overlapping surfaces, connected to the steel structure beams in an overlapping mode, of the steel bar trusses are equivalent in height. According to the steel bar truss plate end connecting joint structure and the construction method thereof, the detachable steel bar truss plates are assembled at a small area on site, thus hoisting and assembling of the steel bar truss plates are convenient and easy, the single steel bar truss plate can be welded and fixed after being assembled, the adjacent steel bar truss plates are mutually supported through the supporting pieces, thus the dislocation gaps of the steel bar truss plates are reduced, and a floor surface is flat and can be directly whitewashed, mounted and dismounted.

Description

technical field [0001] The invention relates to the field of concrete structure building construction, in particular to a connection node structure and a construction method at the ends of steel bar truss plates. Background technique [0002] At present, horizontal structural formwork projects in my country's construction industry generally adopt bent frame support, supplemented by wooden squares and plywood or formwork. Its technological principle provides support for the floor slab by setting up a bent support system to meet the bearing capacity and deformation requirements during the construction stage. Due to the cumbersome and complicated process of the bent support system, foundation treatment, erection of scaffolding, installation of formwork, binding of steel bars, concrete pouring, maintenance, and formwork removal will take up a lot of time and construction period, and the rental management cost of scaffolding is high. Hazards of working at heights. [0003] In r...

AI Technical Summary

Problems solved by technology

The formwork can be reused, the cost is reduced, and the secondary decoration is convenient. However, it can only be applied to the frame beam structure, and it is rarely used on the steel structure beam. Moreover, it is difficult to lift the formwork of the reinforced grid structure, and the large-area The installation nodes of the composite formwork of the reinforced grid frame are complicated, the connection strength is low, and the load-bearing capacity is weak
