Description

Straight thread sleeve connects precast concrete frame Technical Field The utility model relates to the technical field of civil engineering, in particular to a straight thread sleeve connection precast concrete frame. Background The prefabricated concrete frame structure is an industrialized building production mode and meets the requirement of green sustainable development of industrialized mass production. The precast concrete structure has the advantages of high production efficiency, high construction speed, energy conservation and emission reduction, good product quality, small environmental impact, capability of saving templates in a large amount and the like. In recent years, along with the promotion of the industrialization and industrialization of the residences in China, the prefabricated concrete frame structure has great development potential and space. Currently, precast concrete frame structures mainly used at home and abroad form a bearing system by structural members such as precast beams, columns, floors and the like. The connection between precast concrete elements is typically made by post-cast concrete, prestressing, welded connections, bolted connections, grouting sleeve connections, and the like. However, these connection schemes have problems in practical application, such as large wet workload of post-cast concrete site, low assembly efficiency, complex prestress connection process, high cost, high construction requirement of welding connection, low construction efficiency, difficult quality assurance, poor anti-seismic performance, complex structure of connectors required by bolt connection, relatively high price, poor compactness of grouting materials of sleeve grouting connection, difficult quality control and the like. The problems existing in the connection scheme become one of the main factors restricting the popularization and application of the precast concrete frame structure.
