Group welding method of auxiliary steel box beam group welding device

Abstract

The invention discloses a group welding method of an auxiliary steel box beam group welding device and provides an auxiliary steel box beam group welding device. The auxiliary group welding device comprises a machine frame, a compressing assembly, at least one limiting clamp and a driving mechanism, wherein the compressing assembly comprises two compressing disks which are arranged at intervals; the limiting clamp comprises two limiting plates, and the two limiting plates are respectively arranged on the two sides of the compressing assembly; the driving mechanism is used for driving the compressing disks to move in the direction close to or far from the limiting clamp. Two auxiliary group welding devices are arranged at intervals in the length direction of a steel box beam bottom plate, and steel box beam wall plates on the two sides of the steel box beam bottom plate are respectively arranged between the compressing disks and the limiting plates; by adjusting the distance between thetwo limiting plates, the limiting plates can abut against the steel box beam wall plates; the driving mechanism is used for driving the compressing disks, so that the compressing disks and the limiting plates can clamp the steel box beam wall plates, and the steel box beam wall plates can be welded to the steel box beam bottom plate. The auxiliary steel box beam group welding device disclosed bythe invention can help group welding of varieties of steel box beams of different specifications and dimensions and solves the problem of fixing damage caused by a point fixing and limiting mode to the wall plates on the two sides.

Description

technical field [0001] The invention relates to the field of steel box girder manufacturing, in particular to a welding method for an auxiliary welding assembly device of a steel box girder. Background technique [0002] Rectangular steel box girder is one of the commonly used structures in steel structure engineering. It is generally welded by the bottom plate, panel segments, side wall plates and middle partitions. Compared with cast-in-place concrete beams, it has lighter weight and is The advantages of less environmental factors and higher strength are now being used more and more in large structures such as large bridges, municipal venues, skyscrapers, and wind tunnels. With the upgrading of product technology, the products of rectangular steel box girder structure are gradually developing towards large-scale and refined. The overall deformation control of rectangular steel box girder after welding is becoming more and more strict. , What kind of process to achieve hig...
