Girth anti-shearing joint structure and construction method
The invention relates to a girth anti-shearing joint structure and a construction method. The joint structure is arranged at the joint of a supporting pile and a girth in a foundation pit enclosure structure. The joint structure comprises an anti-shearing rebar obliquely anchored into the girth. The top end of the anti-shearing rebar stretches out of the girth and forms a stretching section of a vertical main rebar anchored to the supporting pile, and the bottom end of the anti-shearing rebar is flush with a bottom-layer reinforcement of a girth reinforcement cage. The joint structure achievesthe effect of tying through the vertical main rebar of the supporting pile, on the premise of not reducing the anti-shearing force of the girth, the use quantity of reinforcements is reduced, the cost is reduced, the construction efficiency is improved, and the construction period is shortened; and in addition, the length of the anti-shearing rebar is arranged, the bottom end of the anti-shearingrebar is flush with the bottom-layer reinforcement of the girth reinforcement cage, then the bottom end of the anti-shearing rebar can serve as the elevation of the bottom-layer reinforcement of thegirth reinforcement cage, the construction speed is increased, and the construction quality is improved.
本发明涉及一种围梁抗剪切节点结构及施工方法，所述节点结构设于基坑围护结构中支护桩与围梁的连接处，包括倾斜锚固于围梁内的抗剪筋，抗剪筋的顶端延伸出围梁并形成锚固于支护桩的竖向主筋的一延伸段，抗剪筋的底端与围梁钢筋笼的底层钢筋齐平。本发明的节点结构借助支护桩的竖向主筋起到拉结作用，在不降低围梁抗剪力的前提下，降低了钢筋的使用量，节约了成本，提高了施工效率并节约了工期；另外，通过对抗剪筋的长度设置，使抗剪筋的底端满足与围梁钢筋笼的底层钢筋齐平，进而使抗剪筋的底端可以作为围梁钢筋笼的底层钢筋标高，提高施工速度和施工质量。
