A sub-structure modular prefabricated assembled node-type frame structure assembly method

Abstract

A method for assembling a novel substructure module type preformed joint-assembled type frame structure is characterized by comprising two main types of preformed assembled substructures: various types of preformed frame substructure joints and preformed substructures for integral connection establishing. The two types of the preformed assembled substructures can form into a whole through dry type or wet type connection. Planar frame joint substructure assembly units are arranged according to hoisting capacity of hoisting equipment and buildings, and the top floor, the standard floor, the bottom floor, the inner span and the side span are provided with different substructures. The preformed joint frame structures can be extended horizontally and vertically, and frame joints of each roof truss are connected to form an integral structure through the preformed beam substructures. The planar joint frame substructure assembly units can be preformed in factories or on construction site, frame pile assembly joints of the same floor can be staggered and arranged at accurate positions with simple internal force so as to improve anti-seismic performance of buildings.

Description

technical field [0001] The patent of the invention relates to the technical field of civil engineering prefabricated concrete house construction, specifically a reinforced concrete house with frame structure assembled by using prefabricated node-type frame substructures and its assembled construction method, especially the type of prefabricated frame node substructure , style, assembly method, etc. Background technique [0002] The beam-column components of traditional reinforced concrete frame structure buildings are usually casted after the formwork is set up on the construction site. The components are reliable in connection, have good integrity and seismic performance, but the construction period is long and the management is complicated. The prefabricated assembly of frame structure buildings represents an advanced development direction. [0003] At present, my country's prefabricated frame buildings are often prefabricated by small and medium-sized component factories...

AI Technical Summary

Problems solved by technology

At present, the prefabricated parts are often assembled in places where the structural forces are complex and weak, such as beam-column joints, which is unfavorable for earthquake-prone areas. Researchers at home and abroad have proposed strategies to move the assembled parts outward. To achieve the connection of prefabricated beam-column components, but for large prefabricated parts, especially for column-column assembly, there is no feasible and reliable method

[0004] Due to many reasons, the performance of prefabricated building structures is not as expected, such as poor safety performance in previous earthquakes, too many on-site assembly nodes and too concentrated
