Prestressed high-strength steel strip self-tapping screw connection laminated wood splicing joint
The invention relates to a prestressed high-strength steel strip self-tapping screw connected laminated wood splicing joint which comprises laminated wood beams spliced with each other, the end portion of the connecting end of each laminated wood beam extends to form a splicing portion, and the splicing portions of the two laminated wood beams are spliced together in an up-down overlapping mode to form a laminated wood beam splicing area; the connecting pieces penetrate through the mutually spliced laminated wood beams and are fixedly connected with the laminated wood beams; the high-strength steel belt is bent around the splicing area and penetrates through the lock catch to extend, a preset pretension force is applied to the high-strength steel belt, and the high-strength steel belt to which the pretension force is applied is fixed through the lock catch. The joint is simple in structure, convenient to install and reliable in force transmission, the self-tapping screws at different positions play roles in tensile shear resistance, tensile resistance and reinforcement respectively, the high-strength steel strips effectively limit development of cracks, and the bearing capacity and ductility of the joint are guaranteed.
本发明涉及一种预应力高强钢带自攻螺钉连接胶合木拼接节点，包括：相互拼接的胶合木梁，每个所述胶合木梁的连接端的端部均延伸出拼接部，两个所述胶合木梁的拼接部上下交叠拼接在一起构成胶合木梁拼接区域；连接件，所述连接件贯穿相互拼接的胶合木梁并连接固定；高强钢带和锁扣，所述高强钢带环绕所述拼接区域弯折并穿过锁扣延伸，所述高强钢带上施加有预设的预拉力，通过锁扣将施加有预拉力的高强钢带固定。本发明构造简单，安装方便，传力可靠，不同部位的自攻螺钉分别起抗拉剪、抗拉和加强作用，高强钢带则有效限制了裂缝的开展，保证了节点的承载力和延性。
