The invention relates to the technical field of building construction anti-cracking, in particular to a steel structure swivel tool which comprises a swivel spherical hinge tool, the swivel spherical hinge tool comprises a positioning framework, a support is fixedly installed on the bottom face of the positioning framework, a main pier is laid on the bottom face of the support, a lower base is movably installed on the top face of the positioning framework, a lower spherical hinge is fixedly installed on the top face of the lower base, an upper spherical hinge is movably installed on the upper side of the lower spherical hinge, an upper base is fixedly welded to the top face of the upper spherical hinge, a sealing groove is formed in the side face of the lower spherical hinge, and a tidying structure is installed in the swivel spherical hinge tool and comprises a guide column. By arranging the guide columns, the position of the lower base on the top face of the positioning framework can be preliminarily regulated, then the position of the lower base can be further adjusted through pushing of the clamping blocks, it is guaranteed that the lower base is located in the middle of the top face of the positioning framework, and the stability of the swivel spherical hinge tool is improved.
Description
technical field [0001] The technical field of anti-cracking in building construction of the present invention is specifically a kind of swivel tooling of steel structure. Background technique [0002] A swivel bridge is a bridge constructed using the swivel method. Bridge swivel construction refers to a construction method in which the bridge structure is formed (cast or spliced) at a position other than the design axis, and then put in place by swivel. It converts operations over obstacles to operations onshore or near the surface. According to the rotation direction of the bridge structure, it can be divided into vertical rotation construction method, horizontal rotation construction method (referred to as vertical rotation method and rotation method) and a combination of horizontal rotation and vertical rotation method, among which the horizontal rotation method is the most widely used. . It is mainly used in situations where the canyon, river, railway, highway, etc. c...
