Assembly type concrete frame joint with bonded prestress and grout sealing method thereof
The invention discloses an assembly type concrete frame joint with bonded prestress and a grout sealing method thereof. The frame joint comprises a concrete column and at least one concrete notch beam; a bracket is arranged on the side face of the concrete column, the shape of a notch of the concrete notch beam is matched with that of the bracket, and the concrete notch beam is supported on the bracket through the notch of the concrete notch beam; and a metal-rubber composite plate is fixed on the notch end face of the concrete notch beam, the metal-rubber composite plate comprises a metal plate and a rubber sealing layer fixed on the outer surface of the metal plate, and through holes allowing the prestressed steel strand to penetrate through are formed in the middle of the metal plate and the middle of the rubber sealing layer. According to the assembly type concrete frame joint with the bonded prestress and the grout sealing method thereof, the metal-rubber composite plate is adopted at the beam-column joint for pressure sealing through the prestress, the pressure stress of the prestress and the good sealing performance of rubber are reasonably utilized, the problem that the joint connecting position is difficult to seal or not tight in sealing is solved, and the phenomena of grout leakage, insufficient grouting pressure, non-dense grouting and the like in the follow-up grouting process are avoided.
本发明公开了一种有粘结预应力装配式混凝土框架节点及其封浆方法，该框架节点包括混凝土柱和至少一根混凝土缺口梁；混凝土柱的侧面上具有牛腿，混凝土缺口梁的缺口形状与牛腿形状相适配，混凝土缺口梁通过其缺口支撑在牛腿上；混凝土缺口梁的缺口端面上固定有金属橡胶复合板，金属橡胶复合板包括金属板以及固定在金属板外表面上的橡胶密封层，金属板和橡胶密封层的中部开设有供预应力钢绞线穿过的通孔。本发明在梁柱结合处采用金属橡胶复合板通过预应力进行压力密封，合理利用预应力的压应力和橡胶良好的密封性能，解决了节点连接处难以密封或密封不严的问题，避免后续灌浆过程中产生漏浆、灌浆压力不足和压浆不密实等现象。
