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. Further innovative research

Abstract

The invention discloses a fabricated building lotus-root-type beam pre-buried heat-preservation plate post-tensioned anchorage joint structure. The fabricated building lotus-root-type beam pre-buriedheat-preservation plate post-tensioned anchorage joint structure comprises a precast column, precast column vertical outward-extending steel bars, a composite lotus-root-type beam column head, lotus-root-type beam outward-extending composite beams, a composite lotus-root-type beam reserved groove, composite lotus-root-type beam edge side outward-extending steel bars, an XPS heat-preservation plate, unbonded prestressed tendons, outward-extending steel bars at composite grooves, composite lotus-root-type beam upper part exposed steel bars and a flat hidden beam steel bar net. The invention further discloses a construction method of the fabricated building lotus-root-type beam pre-buried heat-preservation plate post-tensioned anchorage joint structure, and the construction method comprises the ten construction steps. According to the fabricated building lotus-root-type beam pre-buried heat-preservation plate post-tensioned anchorage joint structure, the force bearing characteristics of abeam-column joint is effectively improved, through an overall post-cast concrete face layer, the overall force bearing requirement of the beam-column joint is well ensured, and the hogging moment resisting effect of the joint is good; and the hoisting cost is low, the hoisting speed and precision are high, building construction is greatly assisted, and the positive effect on promoting industry modernization of prefabricated building hoisting is realized.

Description

technical field [0001] The invention relates to the technical field of assembled road construction, more specifically, it relates to a pre-embedded thermal insulation board post-tensioning node structure and construction method of lotus root beams in an assembled building. 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 ...
