Prefabricated slab and column mortise and tenon type connecting joint and installation method

Abstract

The invention discloses a prefabricated slab and column mortise and tenon type connecting joint and an installation method. The connecting joint comprises a composite frame column, a floor slab and a high-strength bolt. A column end sealing plate is welded to the top end of a column body, and the bottom end of a column tenon is welded to the column end sealing plate. Frame beams on the periphery are structural steel or structural steel combination trusses. Tenon holes are hollow steel members connected with the frame beams, the cross section shape of the tenon holes is the same as that of the column tenon, and the cross sections of the tenon holes are larger than the cross section of the column tenon but small than the cross section of a body of the composite frame column. Composite frame columns and floor slabs are sequentially connected and fixed through bolt holes and high-strength bolts. By means of tenon and mortise type connection of slabs and columns prefabricated in a factory, the structure form and the installation mode are greatly simplified, the structural safety and quality of a building can be guaranteed better, the field workload is reduced, the construction environment pollution is reduced, the construction period is shortened, and cost is saved.

Description

technical field [0001] The invention relates to a prefabricated slab-column mortise-and-tenon joint and an installation method thereof, belonging to the technical field of construction engineering, in particular to a slab-column joint with an integrated assembly structure and a manufacturing and installation method thereof. Background technique [0002] At present, the degree of assembly of most prefabricated buildings at home and abroad is still at the component level, and there is still a certain gap in the overall modular design, production and installation of panels (wall panels and floor panels), columns, especially in structural integration. There are still great deficiencies in the construction of prefabricated connection nodes. In view of the low assembly level of the current plate-column connection structure, a large amount of labor costs are required for processing and installation, resulting in high cost, the present invention provides a prefabricated plate-column...
