Fabricated beam-column connecting joint based on hidden bracket and construction method of fabricated beam-column connecting joint
The invention discloses a fabricated beam-column connecting joint based on a hidden brackets. The joint is characterized by comprising a prefabricated column and two prefabricated beams, wherein the prefabricated column is vertically arranged, and hidden brackets are arranged on two sides of the prefabricated column; a lower opposite-pulling piece is pre-buried at the lower part in each hidden bracket; the two prefabricated beams are horizontally arranged, and the top elevations of the two prefabricated beams are flush; the ends of the two prefabricated beams are in lap joint with the hidden brackets on two sides of the prefabricated column correspondingly, and concrete is poured into gaps between the prefabricated beams and the prefabricated column and gaps between the prefabricated beams and the brackets. Pre-embedded profile steel is arranged at the lap joint ends of the two prefabricated beams respectively, and the pre-embedded profile steel is connected with the two ends of the lower opposite-pulling piece; and the bottom elevations of the hidden bracket and the two prefabricated beams are flush with each other. The invention further provides a construction method of the fabricated beam-column connecting joint. The method has the beneficial effects that a node form of combining beam-column dry type connection and small-amount wet type connection is adopted, wet operation does not exist in a beam-column node core area, and the work efficiency is high; and the upper longitudinal bars of the beam are communicated through a sleeve, so that upper bending moment can be well transferred.
本发明公开了一种基于暗牛腿的装配式梁柱连接节点，其特征在于，包括预制柱和两个预制梁，所述预制柱竖直布置，预制柱的两侧设有暗牛腿；所述暗牛腿内下部预埋有下对拉件；所述两个预制梁水平布置，二者顶部标高齐平；两个预制梁的端部分别搭接在预制柱两侧的暗牛腿上，预制梁与预制柱和牛腿之间的缝隙内浇筑有混凝土；两个预制梁的搭接端分别设有预埋型钢，预埋型钢与下对拉件的两端相连；暗牛腿及两个预制梁的底部标高齐平。本发明还提供了一种装配式梁柱连接节点施工方法。本发明的有益效果为：本发明采用梁‑柱干式连接和少量湿式连接相结合的节点形式，梁柱节点核心区没有湿作业，工效较高；梁上部纵筋通过套筒贯通，能很好地传递上部弯矩。
