Prestress laminated wood steel filling plate bolt connection joint
The invention provides a prestressed laminated wood steel filler plate bolt connection node, which comprises a laminated wood beam, a steel filler plate and a bolt, and is characterized in that one end of the laminated wood beam is slotted and perforated and is used for inserting the steel filler plate and mounting the bolt; the bolt is connected with the steel filling plate and the laminated wood beam to form a laminated wood steel filling plate bolt connection node; a high-strength steel belt and a lock catch are adopted, the steel belt is bent around a node and penetrates through the lock catch to be pulled out by a certain length, an air pump is used for applying power to a tensioner, the tensioner is used for tensioning the steel belt till the designed pretension force is achieved, and meanwhile a lock catch machine is used for clamping the lock catch to fix the steel belt. The joint is simple in structure, convenient to install and reliable in force transmission, cracks are effectively prevented from appearing and expanding through the high-strength steel belts applying pretension force, the cooperative work performance of the laminated wood beams and the steel filling plates is enhanced, and the bearing capacity and ductility of the joint are obviously improved.
本发明提供一种预应力胶合木钢填板螺栓连接节点，包括：胶合木梁，其一端开槽、开孔，用于插入钢填板和安装螺栓；钢填板和螺栓，螺栓连接钢填板与胶合木梁构成胶合木钢填板螺栓连接节点；高强钢带和锁扣，将钢带围绕节点弯折并穿过锁扣拉出一段长度，利用气泵为拉紧器施加动力，使用拉紧器张拉钢带直至设计预拉力，同时利用锁扣机咬紧锁扣对钢带进行固定。本发明构造简单，安装方便，传力可靠，通过施加预拉力的高强钢带有效阻止了裂缝的出现和扩展，增强了胶合木梁和钢填板的协同工作性能，明显提高了节点的承载力和延性。
