Method for welding connector on stiff tubular column

Abstract

The invention relates to a method for welding a connector on a stiff tubular column. The method comprises the following steps: inputting data of the stiff tubular column and data of each rebar on a beam column joint into a drawing tool at equal proportions, determining the position, angle and elevation of the connector; drawing a connector positioning template in the drawing tool according to the data of the stiff tubular column and the data of position, angle and elevation of the connector; machining and forming the connector positioning template through a numerically-controlled machine tool; welding the connector positioning template on the corresponding position of the stiff tubular column; placing the connector on the corresponding position of the connector positioning template, welding the connector on the stiff tubular column; dismounting the connector positioning template. The investment on the labor charges is reduced; the potential safety hazard caused by operation in a narrow space by a constructor is avoided, the construction quality is strengthened, the mechanization of the building construction and instrumentalization of finished products are realized, the welding of the connector is not needed on the construction site, and the work amount of field welding is reduced.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a method for welding a connector on a rigid circular pipe column. Background technique [0002] In the actual construction process, it is rapidly applied with the stiffened reinforced concrete structure. There are many steel bars crossing at the beam-column joints of rigid circular tubular columns, and the connection is more complicated. There is an angular relationship between the beam and the axis in all directions, and it is difficult to control the angle during the welding process. The traditional method adopts the method of scribing and positioning. Although the method is simple in construction, the amount of welding is large, the connector and welding materials are wasted, and it will make it difficult to guarantee the welding quality of the steel bar connection of the beam-column joint, and there are safety and quality risks. [0003] Therefore, to develop a...
