A prefabricated concrete building connection node

Abstract

The invention discloses an assembled concrete building connection node, which includes a component body, a top plate, a bottom plate and a connection port. The top and bottom ends of the component body are respectively equipped with a top plate and a bottom plate, and the component body and the top plate are connected by bolts. And the upper end surface of the top plate and the bottom plate are respectively connected with the card plate and then the card groove plate. The connection node of the prefabricated concrete building uses a spliced ​​and connected liquid pipe structure between the component bodies, which is convenient for the user to directly transport the concrete curing agent from the bottom to the top of the base column, so that the formed concrete base column is formed by gravity. For comprehensive maintenance, there is no need to use high-pressure equipment such as water guns to spray high-level components or workers to climb up for maintenance. The structural design is more reasonable, and it can use its own gravity when the components are spliced ​​to achieve stable connections between components without using bolts. Or pouring cement for reinforcement, which greatly improves the convenience and stability of the connection between components.

Description

technical field [0001] The invention relates to the technical field of prefabricated concrete buildings, in particular to a connection node of a prefabricated concrete building. Background technique [0002] Prefabricated concrete buildings are components formed by pouring concrete and connected by splicing and fixing to form concrete buildings of a specified shape. Compared with traditional building construction methods, the efficiency is higher and the construction cost is lower. Modular production and reproduction Cooperating with the unified assembly connection in the later stage, the overall construction efficiency of the building is improved. In the process of infrastructure construction, the vertically distributed foundation columns standing on the building or on the ground are generally installed vertically with prefabricated concrete components due to their high height. Composition, in which the connection structure between components, that is, the stability of the ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a prefabricated concrete building connection node to solve the problem mentioned in the background art that the overall height of the base column is relatively high after the base column is completed, and the surface of some concrete base columns will not be protected by ceramic tiles or wall stickers. In order to ensure the service life of the foundation column, the concrete surface will be cured. Because of the high height, it is very inconvenient to spray the curing agent. The existing connection node structure can only play the role of connection, and the function is relatively scarce.
