Beam and pile assembled node of precast and prestressed concrete structure

Abstract

A prestressed concrete frame includes prefabricated beam and pile and integrated by prestressed reinforce. The pile is of a length over 2-3 floors. The beam is of a length for one room. Reinforce inside the beam is of a length at least equal to the short beam line. Binding reinforce concentrated in the beam center zone is of a length at least equal to the short beam line. Structure reinforce is also applied into the beam. Joint reinforce is applied to the beam ends. A distance of 30-40mm left between the beam and pile. This frame is of good stability for earthquake.

Description

technical field The prefabricated prestressed concrete structural beam and column composite joint is a form of joint processing, which belongs to the technical field of fabricated concrete structures in civil engineering. Background technique The seismic performance of prefabricated structures is determined by the connections between prefabricated components. Most areas in my country are in seismic fortified areas, so whether the connection is reliable or not directly affects the application of prefabricated structures. For a long time, due to the unsolved technical problems of assembled structure nodes, the application of assembled structures in my country's earthquake areas has been restricted. The current seismic codes generally encourage the use of cast-in-place nodes, which cause great pollution to the surrounding environment. , such as the waste of construction water and construction materials, and the noise brought by the construction also troubles the surrounding re...
