Auxiliary steel structure funnel segmented butt seam welding method

Abstract

The invention relates to the technical field of steel structure installation construction, in particular to an auxiliary steel structure funnel segmented butt seam welding method. The method comprises the steps that adjustable bolt devices are machined and manufactured, each adjustable bolt device comprises a fixing plate and an adjustable screw, a screw hole matched with the corresponding adjustable screw is formed in each fixing plate, and each adjustable screw penetrates through the corresponding screw hole and can rotate and move; the adjustable bolt devices are evenly distributed on the upper portion of a steel structure funnel, the fixing plates are fixed to the positions, close to a welding seam, of the outer surface of the upper portion of the steel structure funnel, the screw holes cross the welding seam, and the adjustable screws penetrate through the screw holes to be in contact with the lower portion of the steel structure funnel; steel components are assembled, the adjustable screws are rotated to move the lower portions of the steel component funnel, and deviation adjustment is conducted; and after the axis deviation is qualified, temporary fixing and formal welding are conducted, and the adjustable bolt devices are removed after welding is completed. By adjusting the adjustable bolt devices, segmented fine assembling of the steel components can be achieved, the axis deviation is minimized, and the problem of welding deviation is solved.

Description

technical field [0001] The invention relates to the technical field of steel structure installation and construction, in particular to a segmented butt seam welding method for an auxiliary steel structure funnel. Background technique [0002] Due to the large size, heavy weight, and difficult operation of large-scale steel structural components, the method of segmented installation is often adopted during the installation process. Although this method solves the problem of difficult lifting, it also increases the cost of segmented welding assembly of components. The problem is that during the butt welding process of steel components, problems such as axis deviation, welding deformation, and excessive misalignment are prone to occur, resulting in quality defects and even substandard products. The invention aims at solving the purpose of adjusting the joint quality of the components when the steel components are welded in sections through the actual operation on the spot. Co...
