A prefabricated building superimposed lotus root beam-column joint structure and its construction method

Abstract

The invention discloses an assembly-type building laminated lotus-root-shaped beam-column joint structure. The assembly-type building laminated lotus-root-shaped beam-column joint structure comprisesa prefabricated column, prefabricated column vertical protruding bars, a laminated lotus-root-shaped beam-column head, a lotus-root-shaped beam protruding laminated beam, a lotus-root-shaped beam reserved laminated groove, laminated lotus-root-shaped beam side protruding bars, laminated lotus-root-shaped beam upper exposed bars and a flat hidden beam bar net. The invention further discloses a construction method of the assembly-type building laminated lotus-root-shaped beam-column joint structure, and the construction method comprises ten construction steps. The stress characteristic of a beam-column joint is effectively improved, the overall stress demand of the beam-column joint is well met through a whole post-pouring concrete surface layer, and the hogging moment resisting effect of the joint is good; and the lifting cost is low, the lifting speed and precision are high, great help is brought to building construction, the positive effect is achieved on promoting achievement of industry modernization of prefabricated assembly-type building lifting, and a clear idea is provided for innovative research of detailed structural design such as a lifting method and the connection joint.

Description

technical field [0001] The invention relates to the technical field of assembled road construction, more specifically, it relates to a joint structure of stacked lotus root beams and columns of an assembled building and a construction method thereof. Background technique [0002] In recent years, with the continuous development and progress of new building technologies and materials, prefabricated buildings have been widely used. In many countries with developed building industrialization, prefabricated buildings have experienced long-term experiments and applications. Modern prefabricated building products can already highly integrate various functions of buildings, and the forms and components of buildings are very delicate. my country's construction demand is large and the construction speed is fast. It is necessary to develop prefabricated buildings, so the requirements for the construction of prefabricated structural nodes and hoisting technology are also getting higher...

AI Technical Summary

Problems solved by technology

[0003] The traditional composite beam-column joint structure of prefabricated buildings has poor mechanical characteristics of the beam-column joints. The hoisting construction cost of prefabricated structures is high, and the hoisting speed and precision are low, which brings great difficulties to the construction. If the hoisting of prefabricated buildings is to realize industrial modernization, the hoisting methods and detailed structure design of connection nodes need to be improved.
