Cover plate-prestressed high-strength steel strip connection laminated wood mortise and tenon joint
The invention relates to a cover plate-prestressed high-strength steel strip connected laminated wood mortise and tenon joint which comprises laminated wood beams, the end portion of the connecting end of each laminated wood beam is provided with a tenon and a mortise, the tenons and the mortises of the two laminated wood beams are meshed with each other to form a laminated wood mortise and tenon joint, the top face and the bottom face of the end portion of each connecting end are provided with an upper groove and a lower groove, and the upper groove and the lower groove are meshed with each other to form a cover plate-prestressed high-strength steel strip connected laminated wood mortise and tenon joint. The upper cover plate and the lower cover plate are positioned and mounted; the upper cover plate and the lower cover plate are arranged in the upper groove and the lower groove respectively, the steel belt is bent around the laminated wood mortise and tenon joint, the upper cover plate and the lower cover plate and penetrates through the lock catch to be pulled out by a certain length, an air pump is connected with a steel belt packer to tension the steel belt, and the lock catch is clamped through a lock catch machine to fix the steel belt. The joint is simple in structure, convenient to install and reliable in force transmission, the friction force between the tenon and the mortise groove is increased through the upper cover plate, the lower cover plate and the prestress high-strength steel belt, tenon pulling damage and tenon root breaking of the joint can be effectively avoided, and the bearing capacity and rigidity of the joint are obviously improved.
本发明涉及一种盖板‑预应力高强钢带连接胶合木榫卯式节点，包括：胶合木梁，每个胶合木梁的连接端的端部均设置榫头和卯槽，两个胶合木梁的榫头与卯槽相互咬合，构成胶合木榫卯接头，连接端端部顶面和底面设置上、下凹槽，用于定位、安装上、下盖板；上、下盖板以及固定用高强钢带，将上、下盖板分别置于上、下凹槽内，将钢带环绕胶合木榫卯接头及上、下盖板弯折并穿过锁扣拉出一定长度，通过气泵连接钢带打包机拉紧钢带，通过锁扣机夹紧锁扣以固定钢带。本发明构造简单，安装方便，传力可靠，通过上、下盖板和预应力高强钢带增加了榫头与卯槽之间的摩擦力，能有效避免节点发生拔榫破坏和榫头根部折断，明显提高了节点的承载力和刚度。
