Embodiment Construction

[0015] Below in conjunction with accompanying drawing, specific embodiment of the present invention is described in further detail:

[0016] As can be seen from the accompanying drawings, the cast steel spherical hinge support of the present invention is composed of four parts, which are respectively a rotating body 1, a cylindrical support body 2 with a spherical crown, a base 3 and a retaining ring 4. The four parts are all formed by casting, and the material properties and processing must meet the requirements of the current China Engineering Construction Standardization Association standard "Technical Regulations for Cast Steel Joints".

[0017] The radius of the bottom surface of the spherical cap at the top of the cylindrical support body 2 is greater than the radius of the bottom surface of the lower cylinder, so that the spherical cap protrudes outward relative to the cylinder. The cylinder bottom end of the cylinder support body 2 is fixed on the base 3 through screw ...

Abstract

The invention discloses a novel cast-steel spherical hinge support, which comprises a base fixedly connected with a column-shaped supporting body with the top being an evagination crown body which is embedded in a provided groove on the lower end surface of a rolling body, the shape of the inner surface of the provided groove corresponds to that of the evagination crown body, the inner side wall of the provided groove is connected with a baffle ring in a screw way, and the baffle ring is arranged outside the column at the lower part of the evagination crown body. The support can not only meet the rolling demands of the nodes, but also can bear horizontal force and the vertical pull force as well as pressure, thus being mainly used for large-span space structure bearing complicated forces and heavy shaped steel structure.

Description

technical field [0001] The invention relates to a steel structure support, in particular to a cast steel spherical hinge support suitable for complex structures. Background technique [0002] The steel structure supports recommended in the current "Code for Design of Steel Structures" (GB50017-2003) are mainly divided into flat support, arc support, roller support, hinge support, spherical support, etc. according to their structural forms. , these types of supports are mainly suitable for steel structures with relatively simple stress and low requirements for support deformation. For example, flat bearings and arc bearings are only suitable for steel structures with small spans that are subject to tension or pressure, spherical hinge pressure bearings can only rotate but not translate, fixed hinge bearings can only rotate around the hinge axis and cannot Any movement perpendicular to the hinge axis, etc. At present, there is no support in the project that can meet the rota...
