Abstract

The invention discloses a special single-beat welding machine for steel bar trusses on an automatic production line of steel bar trusses. The special single-beat welding machine structurally comprises a machine base, a worktable, an upper welding device and a lower welding device, wherein the worktable is mounted on the machine base, a web member steel bar positioning and tensioning device, an upper string rib support and the upper welding device are arranged at the front end of the machine base, and the lower welding device and the steel bar truss positioning and guiding device are arranged at the rear end of the machine base. Lower string rib positioning and guiding devices are symmetrically arranged on two sides of the worktable. The web member steel bar positioning and tensioning device can fixe relative positions of web member steel bars and upper string ribs before the steel bar trusses are welded. The upper string rib support can be applicable to production of the steel bar trusses different in height, and the upper string ribs and the lower string ribs are respectively welded with the web member steel bars by the upper welding device and the lower welding device. After welding and forming, the steel bar trusses are fed to subsequent production units by an automatic step system. The special single-beat welding machine is simple in structure, high in automation degree and low in production cost.

Description

technical field [0001] The invention belongs to the technical field of steel bar truss production, in particular to a single-beat special welding machine for steel bar trusses in a numerical control production line of triangular steel bar trusses. Background technique [0002] At present, steel trusses have gradually been widely used in roof trusses, bridges, high-speed railway sleepers and floor decks of high-rise buildings. The steel truss is formed by welding and shearing three main chord bars and two bent web bars. The truss member mainly bears axial tension or pressure, can make full use of the strength of the material, saves material, reduces self-weight and increases rigidity compared with solid web beam material. After the steel bar truss is welded and formed, it is welded with galvanized steel plate to form a formwork, which can be directly laid on the steel beam, and then simple steel bar engineering and other corresponding work can be performed to pour concrete, ...
