Prestress embedded steel bar connection splicing wood beam
The invention discloses a prestressed embedded steel bar connection spliced wood beam which comprises a plurality of wood beam sections which are connected into a complete wood beam through nodes, and each wood beam section is formed by cutting off a complete giant wood beam according to actual transportation conditions; the joint comprises hardware at the two ends of the wood beam section and an inhaul cable at the bottom of the wood beam. The hardware is implanted into the two ends of the wood beam section through the screws connected with the hardware in a bolted mode, the inhaul cable is buckled in a cable groove in the bottom of the wood beam through a matched cable saddle, and the end of the inhaul cable is anchored to the hardware through a sleeve. And hardware at the end parts of different wood beam sections is connected through field welding. According to the prestressed embedded steel bar connection spliced wood beam disclosed by the invention, the hardware is fixed on the wood beam at the end part in an embedded steel bar screw mode, and the tensile property of the wood beam at a rigid node is improved by utilizing an embedded steel bar connection rift-grain force transfer mode, so that the brittle failure of tensile splitting of a wood tensile area is avoided. And meanwhile, for the outer-layer embedded steel bars under the action of long-term high-strength load, the zippers additionally embedded into the wood beam at the bottom of the beam can play a role in replacement when the zippers fail to work. The method is high in bearing capacity, reliable and stable in system and easy to machine. The method is suitable for the structural fields of large-span buildings, bridges and the like.
本发明公开了一种预应力植筋连接拼接木梁，包括通过节点连接成完整木梁的多个木梁段，所述木梁段由一根完整巨型木梁根据实际运输条件截断而成；所述节点包括木梁段两端的五金件和木梁底部的拉索。所述五金件通过与之栓接的螺杆植入木梁段两端，所述拉索通过配套索鞍卡扣在木梁底部索槽内、拉索端部通过套筒锚固在五金件上。不同木梁段端部五金件通过现场焊接连接。本发明所公开的预应力植筋连接拼接木梁，在端部通过植筋螺杆方式将五金件固定于木梁之上，利用植筋连接顺纹传力的方式，提高了木梁在刚性节点处抗拉性能，避免木材受拉区发生受拉劈裂的脆性破坏。同时，对长期高强荷载的作用下的外层植筋，梁底附加嵌入木梁的拉锁可在其失效时起到替代作用。本发明承载力高、体系可靠稳定、加工简易。本发明适用于大跨度建筑、桥梁等结构领域。
