Precast beam bottom bar anchorage device, precast beam composed of precast beam bottom bar anchorage device and connecting joint
The invention provides a precast beam bottom bar anchorage device, a precast beam composed of the precast beam bottom bar anchorage device and a connecting joint. A precast beam bottom bar is anchored to a joint area at the beam end through a flexible steel wire rope or a prestressed bar, one end of the steel wire rope or the prestressed bar presses a straight thread sleeve to be mechanically connected with the precast beam bottom bar through a straight thread sleeve connector, and the anchoring sleeve is pressed at the other end to enhance the anchoring performance of the steel wire rope or the prestressed tendon in the joint area. The precast beam bottom bar is anchored in the joint area through the flexible steel wire rope or the prestressed bar, the problems of steel bar collision and the like caused by the fact that a traditional prefabricated beam bottom bar directly stretches into the joint area to be anchored can be solved, the precast beam installation efficiency is improved, and machining allowable errors are relieved; and meanwhile, the minimum width of the precast beam constructed by adopting the anchorage device and the connecting joint can be reduced by more than 100mm compared with that of the precast beam constructed by adopting the traditional form.
一种预制梁底筋锚具及其组成的预制梁和连接节点，预制梁底筋在梁端通过柔性的钢丝绳或预应力筋锚固于节点区，钢丝绳或预应力筋一端压制直螺纹套筒与预制梁底筋通过直螺纹套筒接头实现机械连接，另一端压制锚固套筒增强钢丝绳或预应力筋在节点区的锚固性能。本发明预制梁底筋在节点区通过柔性的钢丝绳或预应力筋锚固，可避免传统预制梁底筋直接伸入节点区锚固带来的钢筋碰撞等问题，提高预制梁安装效率，放松加工允许误差，同时采用本发明锚具及连接节点构造的预制梁最小宽度可较传统形式减小100mm以上。
