Connecting joint of assembly type concrete prefabricated wallboards and installation method of connecting joint

Abstract

The invention provides a connecting joint of assembly type concrete prefabricated wallboards and an installation method of the connecting joint. The connecting joint comprises a plurality of grooves which are formed in the periphery of the prefabricated wallboards, connecting plates and connecting bolts, the connecting plates and connecting bolts are embedded in the grooves, the grooves are symmetrically formed in the two faces of the prefabricated wallboards in the thickness direction, a plurality of through connecting holes are formed in the grooves, through holes corresponding to the positions of the connecting holes in the grooves are formed in the connecting plates, the connecting bolts penetrate through the two connecting plates in the two grooves symmetrically formed in the two faces of the prefabricated wallboards in the thickness direction and the connecting holes in the grooves, the two ends of the connecting bolts are fastened by utilizing nuts, and the connecting joints between the two prefabricated wallboards are connected and fastened by screwing the nuts. According to the connecting joint of the assembly type concrete prefabricated wallboards and the installation method of the connecting joint, through the provided connection mode between the prefabricated concrete wallboards, on-site complete dry method operation can be achieved, the installation efficiency of the prefabricated concrete wallboards is greatly improved, the on-site operation time is shortened, and the standardization degree is high.

Description

technical field [0001] The invention belongs to the field of building structures, and in particular relates to a connection node of an assembled concrete prefabricated wall panel and an installation method thereof. Background technique [0002] The prefabricated concrete structure is a structure assembled by prefabricated concrete components through reliable connection. It has factory production of most components, no or less wet work on site, fast installation speed, less impact on the surrounding environment, and easier to guarantee the quality of the house. And the significant advantages such as reducing construction waste are the development direction of my country's construction industry. [0003] Although the prefabricated concrete structure has obvious advantages at present, after more than ten years of practice, there are still shortcomings such as low standardization, many on-site wet operations, inconvenient transportation, and the quality of sleeve grouting is not ...

Problems solved by technology

[0003] Although the prefabricated concrete structure has obvious advantages at present, after more than ten years of practice, there are still shortcomings such as low standardization, many on-site wet operations, inconvenient transportation, and the quality of sleeve grouting is not easy to guarantee, especially the on-site connection between prefabricated wall panels. pouring of concrete

These problems lead to its high cost, which seriously restricts the promotion and application of prefabricated concrete structures.
