Column joint structure of building and connection method thereof

Abstract

The invention discloses a column joint structure of a building and a connection method thereof. Mutually connected column joints between an upper layer column and a lower layer column are of concave-convex matching structural forms, that is, a concave spherical surface is arranged in the center of the column top surface of the lower layer column, while a convex spherical surface is arranged on the column bottom surface of the upper layer column at an opposite position; the concave spherical surface and the convex spherical surface form joints capable of rotating relatively; and connecting plates connected between the upper layer column and the lower layer column along a longitudinal direction are uniformly distributed on the peripheries of the upper layer column and the lower layer column. The column joint structure of the building can enable a pre-fabricated structure to fully meet the requirements of heavy load, crake resistance, strong integrity and rapid industrial production.

Description

technical field [0001] The invention relates to a structure of column joints of buildings and a connection method thereof. Background technique [0002] At present, the column joint structure of buildings can be divided into prefabricated structure construction methods, and the connection of load-bearing components can be divided into wet connection and dry connection. Wet connections require the pouring of concrete or grout between the two members being joined. To ensure the integrity of the connection, the two members need to be lapped or mechanically connected with protruding reinforcement before pouring the concrete. This wet connection method is to form cast-in-place reinforced concrete nodes by pouring concrete after the steel bars are connected. [0003] Dry connection is to implant steel plates or other steel parts in the two components to be connected, and mechanically connect the outstretched steel plates of the two components by bolts or welding to achieve the p...

AI Technical Summary

Problems solved by technology

During the period, the correct position of the components is maintained by temporary support, and the load cannot be applied until the strength of the cast-in-place concrete is satisfied. There are problems such as complex reinforcement layout, difficult operation, difficult quality assurance, and long waiting period for the operation, especially the problem of waiting for the strength of the concrete. The advantages of industrialized operations of prefabricated structures are completely lost

Commonly used prefabricated frame dry joints have indirect force transmission, are not easy to construct, especially have poor reliability, and are difficult to meet the mechanical requirements under repeated loads. The problem of limited use in earthquake areas is a fundamental problem
