Beam column energy dissipation connecting piece and construction method thereof
The invention discloses a beam column energy dissipation connecting piece and a construction method thereof. The beam column energy dissipation connecting piece comprises a connecting end plate, the connecting end plate is vertically arranged at a connecting joint of a prefabricated beam and a prefabricated column, energy dissipation piece mounting grooves are symmetrically formed in the upper portion and the lower portion of the beam end of the prefabricated beam, and two energy dissipation units are arranged in the upper energy dissipation piece mounting groove and the lower energy dissipation piece mounting groove correspondingly; one end of the energy dissipation unit is fixedly connected with the connecting end plate, and the other end of the energy dissipation unit is fixed with the beam end face of the prefabricated beam; prestressed tendons are arranged between the connecting end plates and the beam ends of the prefabricated beams, one ends of the prestressed tendons are fixedly inserted into the prefabricated beams, and the other ends of the prestressed tendons penetrate through the connecting end plates and then are anchored on the connecting end plates through bolts; and the prestressed tendons are arranged between the connecting end plates and the prefabricated beams, so that prefabricated parts can be recovered to the initial device as much as possible after an earthquake. According to the beam column energy dissipation connecting piece, the energy dissipation piece mounting grooves are formed, so that a large rotating space is provided for the beam ends of the prefabricated beams, the energy dissipation units can be fully deformed under the action of the earthquake, and the energy dissipation capacity of the beam column energy dissipation connecting piece is effectively improved.
本发明公开了一种梁柱耗能连接件及其施工方法，包括连接端板，连接端板竖向设置在预制梁与预制柱的连接节点处，预制梁的梁端上下对称设置有耗能件安装槽，两个耗能单元分别设置在上下两个耗能件安装槽中；耗能单元的一端与连接端板固定连接，另一端与预制梁的梁端面固定；预应力筋设置在连接端板与预制梁的梁端之间，预应力筋的一端固定穿插在预制梁中，另一端贯穿连接端板后，并通过螺栓锚固在连接端板上；本发明在连接端板与预制梁之间设置预应力筋，能够使预制构件在震后尽可能恢复到初始装置；通过设置耗能件安装槽，为预制梁的梁端提供了较大的转动空间，以使耗能单元在地震作用下能够充分变形，并有效提高了梁柱耗能连接件的耗能能力。
