Problems solved by technology

[0004] Therefore, the rotating external wall panels are widely used in office public buildings. Generally, the lower nodes of the rotating external wall panels are used as load-bearing nodes and at the same time, they should have a tie effect on the wall panels outside the plane to prevent the wall panels from falling off. The upper nodes are only used as tension nodes. Nodes do not bear gravity loads, which is prone to the problem that precast concrete external wall panels deform unevenly when rotating and cannot meet their deformation requirements

Abstract

The invention relates to aconnecting load-bearing joint structure of an adjustable rotary precast concrete exterior hanging wall panel and a steel beam and a construction method.The connecting load-bearing joint structurecomprises the precast concrete exterior hanging wall panel, and the precast concrete exterior hanging wall panel is connected with a main structure through a steel bracket structure; thesteel bracket structure includes a steel bracketbody, and a vertical steel plate of thesteelbracketbody is parallel with the precast concrete exterior hangingwall panel, and U-shaped grooves and circular holes are symmetrically formed in the two sides of the central line at which the vertical steel plateis perpendicular to a transverse bottom plate; and the U-shaped groovesare internally provided with rotatable connecting structures, andcircular holes are internally provided with horizontal positioning structures; and a large circular hole is formed in the transverse bottom plate of the steel bracketbody, a load-bearing structure is installed in the large circular hole, an embedded structure is arranged in a concrete floor slab, and the load-bearing structure is fixed to the steel beam through the embedded structure.According to the connecting load-bearing joint structure, stressis simple and clear, and the elevation and horizontal position of the precast concreteexterior hanging wall panel can be adjusted, so that on-site construction and installation arefacilitated.

Description

technical field [0001] The invention relates to an adjustable rotary prefabricated concrete external hanging wall panel and a steel beam connection load-bearing node structure and a construction method, belonging to the technical field of assembled structures. Background technique [0002] Prefabricated concrete external wall panels are suitable for external wall projects of industrial and civil buildings. In recent years, with the development of prefabricated buildings, they have also been applied to a certain extent in China. [0003] According to different movement modes, precast concrete external wall panels can be divided into rotary type, translational type, and fixed type; among them, the external wall panels of the rotary external wall panels will rotate in the plane under the action of wind load or earthquake, and the external wall panels can Release the internal force of the nodes generated by its own temperature and adapt to the deformation of the main structure, ...
