Fabricated prefabricated tubular column shear-resistant connecting structure and construction method thereof
The invention discloses an assembly type prefabricated tubular column shear connection structure which comprises a prefabricated upper column and a prefabricated lower column. The prefabricated upper column comprises a concrete upper column, an upper sleeve and an upper connecting piece; the prefabricated lower column comprises a concrete lower column, a lower sleeve and an anti-shearing piece; the anti-shearing piece comprises a conical pipe body, a connecting pipe and a plurality of anchoring steel bars. A plurality of first lower studs extending in the radial direction are fixedly arranged on the surface of the conical pipe body; and a plurality of second lower studs extending back to the center of the connecting pipe are fixedly arranged on the surface of the connecting pipe. The invention further provides a construction method of the fabricated prefabricated tubular column shear-resistant connecting structure. According to the invention, the capability of dissipating earthquake energy at the connection node is enhanced, and the reliability of the connection node is enhanced; the contact area between the shear-resistant piece and the concrete is increased through the studs on the surface of the shear-resistant piece, the shear-resistant effect can be achieved, the shear-resistant performance and the connection reliability between the prefabricated upper column and the shear-resistant piece are enhanced, and the mechanical property of the connection joint is further improved.
本发明公开了一种装配式预制管柱抗剪连接结构，包括：预制上柱和预制下柱；预制上柱包括：混凝土上柱、上套筒和上连接件；预制下柱包括：混凝土下柱、下套筒和抗剪件；抗剪件包括：锥形管体、连接管和多个锚固钢筋；锥形管体的表面固定设置有多个沿径向延伸的第一下栓钉；连接管表面固定设置有多个背向连接管的中心延伸的第二下栓钉。本发明还提供一种装配式预制管柱抗剪连接结构的施工方法。本发明增强了连接节点处耗散地震能量的能力，增强了连接节点处的可靠性；抗剪件表面的栓钉增大了抗剪件与混凝土之间接触面积，且能够产生抗剪作用，增强了预制上柱和抗剪件之间的抗剪性能和连接可靠性，进一步提高了连接节点处的力学性能。
