Construction method for connecting primary structure and secondary structure on curved surface

Abstract

The invention relates to hook face arc-shaped structure construction. A construction method for connecting a main structure and a secondary structure of a hook face comprises the steps that connecting pieces are machined, specifically, a connecting plate welded to the main structure and a T-shaped plate connected with the connecting plate are included, the bottom of the connecting plate is machined to be matched with the radian of the main structure of the hook face to facilitate welding-connecting of the connecting plate and the main structure of the hook face, a transverse arc-shaped long kidney-shaped hole is formed in the middle of the connecting plate, and a longitudinal long kidney-shaped hole is formed in a web of the T-shaped plate; hook face fixed-position welding is conducted; the height and the angle are adjusted, specifically, the height and the angle of the T-shaped plate are adjusted according to the radian and the angle of the secondary structure; and bolt screwing is conducted, specifically, the step of bolt connecting is the final working procedure of overall installation of the connecting plate of the hook face, the connecting plate is welded to the main structure, and the T-shaped plate is in complete contact with the secondary structure according to the shape of the secondary structure and then fixedly connected by using bolts penetrating through the long kidney-shaped hole in the web and the arc-shaped long kidney-shaped hole in the connecting plate. According to the construction method for connecting the main structure and the secondary structure of the hook face, the problem that effective connection cannot be conducted due to errors of the main structure and the secondary structure is solved, machining is convenient, the construction period is shortened, and installation is simple.

Description

technical field [0001] The invention relates to the construction of a curved surface arc structure, in particular to a method for adjusting error when a curved surface main structure and a secondary structure are connected. Background technique [0002] Many modern construction projects have strange shapes, and most of them are based on steel structures. When decorating the surface of buildings and structures, the steel structure is connected to the secondary structure, and then the secondary structure is used to connect the external decoration materials. The steel structure is processed in the factory, bent, welded and hoisted at the construction site, and there will be errors in each step. There will also be errors in the bending of the secondary structure in the factory. When the two are connected at the construction site, there are errors that cannot be effectively connected with a fixed-size connecting plate. In this case, modifying the main structure and the seconda...
