Self-resetting beam column energy dissipation connecting piece and construction method thereof
The invention discloses a self-resetting beam column energy dissipation connecting piece and a construction method thereof. The self-resetting beam column energy dissipation connecting piece comprises a column side end plate, the column side end plate and a beam side end plate are vertically arranged at a beam column joint in parallel, and connecting profile steel is fixedly arranged between the column side end plate and the beam side end plate; two energy dissipation units are symmetrically arranged on the upper side and the lower side of the connecting profile steel; a shear-resistant piece and a prestressed tendon are arranged between the beam side end plate and the beam end of a prefabricated beam, one end of the shear-resistant piece is fixedly connected with the beam side end plate, and the other end of the shear-resistant piece extends into the beam end of the prefabricated beam; one end of the prestressed tendon is fixedly inserted into the prefabricated beam; and the other ends of the prestressed tendons penetrate through the beam side end plates and then are anchored on the beam side end plates through bolts. The prestressed tendons are anchored with the beam end plates of the beam column energy dissipation connecting piece, so that the prestressed tendons can be tensioned in a prefabrication factory, and the self-resetting capability of a component is ensured to the maximum extent; and the shear-resistant pieces can share shear force and bending moment borne by the prestressed tendons, and stress loss caused by deformation of the energy dissipation connecting pieces is weakened.
本发明公开了一种自复位梁柱耗能连接件及其施工方法，包括柱侧端板，柱侧端板与梁侧端板竖向平行设置在梁柱节点处，连接型钢固定设置在柱侧端板与梁侧端板之间；两个耗能单元对称设置在连接型钢的上下两侧；抗剪件及预应力筋均设置在梁侧端板与预制梁的梁端之间，抗剪件的一端与梁侧端板固定连接，另一端伸入至预制梁的梁端；预应力筋的一端固定穿插在预制梁中；预应力筋的另一端贯穿梁侧端板后，通过螺栓锚固在梁侧端板上；本发明将预应力筋与梁柱耗能连接件的梁端端板锚固，能够实现在预制工厂完成对预应力筋的张拉，最大限度的保证了构件的自复位能力；抗剪件能够分担预应力筋承担的剪力与弯矩，减弱了耗能连接件变形带来的应力损失。
