Steel bar truss machining system for manufacturing steel-concrete structure assembly type prefabricated wall body

Abstract

The invention relates to a steel bar truss machining system for manufacturing steel-concrete structure assembly type prefabricated wall body. The steel bar truss machining system comprises a rack, anupper support positioning mechanism, an intermittent conveying mechanism, a lower support positioning mechanism and a front blocking and positioning assembly; the upper support positioning mechanism comprises a lifting fine adjustment table arranged on a main support table and a row of upper support wheels distributed above the main support table; and the lower support positioning mechanism comprises two adjusting positioning air cylinders, a lower support plate, an auxiliary positioning plate and a lateral pressing assembly. According to the steel bar truss machining system, rapid auxiliary positioning can be conducted on a steel bar truss structure of the prefabricated wall, the problem that accurate lap joint forming is not easy in the actual welding process is solved, the effectivenessof lap joint contact of the steel bar truss structure is guaranteed, pseudo soldering points can be effectively prevented from being formed, the welding efficiency is improved, and meanwhile the welding quality of the steel bar truss structure is guaranteed.

Description

technical field [0001] The invention relates to the technical field of production of building materials, and specifically proposes a steel bar truss processing system for an assembled prefabricated wall of a steel-concrete structure. Background technique [0002] Prefabricated wall refers to a steel-concrete structure that can be assembled by laminating prefabricated panels and cast-in-place reinforced concrete layers. The prefabricated wall has good integrity, and the wall surface is flat, which is convenient for decoration of the facing layer. It is suitable for high-rise buildings and large-bay buildings that require high overall rigidity. In the prefabricated wall, steel members such as steel mesh and steel truss will be set to enhance the structural strength. The steel truss structure is mainly welded by broken line steel bars and straight steel bars. The specific structure is as attached Figure 9 As shown, the steel truss structure is composed of two broken-line steel...

AI Technical Summary

Problems solved by technology

In the prefabricated wall, steel members such as steel mesh and steel truss will be set to enhance the structural strength. The steel truss structure is mainly welded by broken line steel bars and straight steel bars. The specific structure is as attached Figure 9 As shown, the steel truss structure is composed of two broken-line steel bars welded in a triangle lap, No. 1 steel bar welded between the two broken-line steel bars, and two No. The structure is formed by welding. During the welding process of the steel truss structure, it is necessary to ensure that the two broken-line steel bars, the No. 1 steel bar and the two No. 2 steel bars are as follows: Figure 9 In the lap joint state shown, in actual welding, due to the long size of the steel bars, it is difficult to realize the welding positioning of the truss structure, which is more troublesome. In addition, often due to the invalid contact of the lap joint, false welding occurs, which affects the prefabricated wall Structural strength and production quality of the body
