Abstract

The invention discloses a novel welding device for welding a steel truss. One of the two steel pipes for welding is horizontally and fixedly placed between two fixing plates, and the other one is placed into a first groove in an inclined manner, and is fixed by a clamping device, wherein the inclination angle of the second steel pipe is adjusted by adjusting the length of a first telescopic pipe and the length of a second telescopic pipe; identical through grooves are formed in the four corners of the first fixing plate and the four corners of the second fixing plate respectively, a connectingrod is arranged between two through grooves on the same vertical straight line in the first fixing plate in a connected manner as the same in the second fixing plate, and the distance between the first fixing plate and the second fixing plate is adjusted through the connecting rods so as to enable welding points of two steel pipes make contact with each other and located in an interval between the first fixing plate and the second fixing plate. The novel welding device for welding the steel truss is simple in structure, and convenient to operate and use.

Description

technical field [0001] The invention relates to the field of construction, in particular to a welding device for welding steel trusses. Background technique [0002] Steel trusses refer to trusses made of steel, roof structures such as crane girders, bridges, and hydraulic gates for industrial and civil buildings. Steel trusses are commonly used as the main load-bearing components. Various towers, such as mast towers, TV towers and transmission line towers, are commonly used as space steel trusses composed of three-sided, four-sided or multi-sided planar trusses. The most commonly used is the plane truss, and its stress is essentially a lattice beam under the action of lateral load. Compared with the steel beam of the solid web type, the steel truss is characterized by replacing the flange with the chord and the web with the web, and connecting the web at each node through the gusset plate (or other parts) with welds or other connections. The rods and chords are connected ...
