Embodiment 1

[0069] Such as figure 1 As shown, the present invention provides a prestressed prefabricated concrete beam-column connection node, which is a middle node, including a precast concrete column 2, a first anchor embedded component 2.1 arranged in the precast concrete column 2, and a precast concrete beam 1.1 , the beam post-cast laminated layer 1.2 arranged on the upper part of the precast concrete beam 1.1, the beam top energy-dissipating steel bar 1.5 arranged in the beam post-cast laminated layer 1.2, and the steel bars arranged at the joint between the precast concrete beam 1.1 and the precast concrete column 2 The adhesive layer 6, and the post-tensioned prestressed tendon 3 for connecting the precast concrete column 2 and the precast concrete beam 1.1. The use of post-tensioned prestressed steel tendons 3 makes the structure have a certain self-recovery property under earthquake action.

[0070] Such as figure 2 , 3 As shown, this node is a middle node, and the precast ...

Embodiment 2

[0084] see Figure 14 shown. Embodiment 3, a prestressed prefabricated concrete beam-column connection node and construction method, the same as embodiment 2, the difference is that the connection node is a corner node, and the prefabricated concrete beam 1.1 is L-shaped, including a horizontal prefabricated main beam and a longitudinal prefabricated beam. Main beam.

Abstract

The invention discloses a prestressed fabricated concrete beam-column connection joint and a construction method thereof. The prestressed fabricated concrete beam-column connection joint includes a precast concrete column, a first anchoring pre-embedded assembly arranged in the precast concrete column, a precast concrete beam, a beam post-poured laminated layer arranged on the upper part of the precast concrete beam, beam top energy-consuming steel bars arranged in the beam post-poured laminated layer, a bonding layer arranged at the joint of the precast concrete beam and the precast concretecolumn, and post-tensioned prestressed tendons for allowing the precast concrete column to be connected with the precast concrete beam, and the first anchoring pre-embedded assembly includes a first pre-embedded part body, a nut, inter-column anchoring steel bars in the column arranged in the first pre-embedded part body and equicohesive mechanical connection joints arranged at the end tips of theinter-column anchoring steel bars. A prestressed fabricated concrete structure frame system with the beam-column semi-dry connection joint is adopted, longitudinal bar at the beam bottom does not extend into the joint area, the problems of steel bar avoidance at the joint and concrete pouring by form erecting on site are solved, and the production, construction and installation efficiency of theprecast concrete beam is improved.

Description

technical field [0001] The invention relates to the field of assembled structural buildings, in particular to a prestressed assembled concrete beam-column connection node and a construction method. Background technique [0002] At present, the multi-high-rise prefabricated concrete frame structure mainly adopts the assembled integral structure system with beam-column joints cast in place. [0003] The problems existing in the construction area of ​​beam-column cast-in-place joints are as follows: first, it is difficult to avoid steel bars; second, the formwork support is complicated; third, the concrete curing time limits the construction efficiency, and the construction efficiency is low. Contents of the invention [0004] The purpose of the present invention is to provide a prestressed assembled concrete beam-column connection node and construction method, to solve the technical problems of slow construction speed of beam-column cast-in-place joints, complicated formwork...
