Combined energy dissipation connecting piece and construction method
The invention discloses a combined energy dissipation connecting piece and a construction method. According to the combined energy dissipation connecting piece and the construction method, the two ends of an energy dissipation piece are inserted into clamping grooves of two embedded parts, a connecting plate and the embedded parts are fixed to form the whole connecting piece, when the initial load of stress is small, a lead core firstly enters in plastic deformation energy dissipation, at the moment, a connecting steel plate is still in an elastic deformation state, therefore, under the action of earthquake force, the energy dissipation piece firstly enters in a plastic stage to start energy dissipation, the lead core has large plastic deformation along with the increase of load, and the connecting steel plate gradually changes from elastic deformation to plastic deformation to start energy dissipation. The connecting plate enters in a plastic deformation state after the energy dissipation piece generates certain plastic deformation, the connecting plate serves as a second energy dissipation defense line of the connecting piece to prevent the connecting piece from being suddenly damaged, and the slotted hole design can prevent the connecting piece from warping out of a plane, so that the effects of plastic deformation as large as possible and seismic force improvement are achieved, the stability of a building is guaranteed, and the use value and the popularization value of the device are high.
本发明公开的一种组合耗能连接件及施工方法，将耗能件的两端与插入两个预埋件的卡槽中，连接板与预埋件固定形成整个连接件，受力初期荷载较小时，首先由铅芯进入塑性变形耗能，此时连接钢板仍处于弹性变形状态，因此在地震力作用下耗能件率先进入塑性阶段开始耗能，随着荷载增加，铅芯已发生较大塑性变形，连接钢板逐渐由弹性变形转变为塑性变形状态开始耗能。连接板在耗能件发生一定塑性变形后进入塑性变形状态，充当连接件的第二道耗能防线可防止连接件发生突然破坏，且其开槽孔设计可避免其发生平面外翘曲，以便发挥尽可能大的塑性变形，提高地震力的效果，保证建筑的稳定性，具有较大的使用价值和推广价值。
