CFRP cable-laminated wood combined beam string structure system
The invention discloses a CFRP cable-laminated wood combined beam string system which comprises a CFRP cable, a sectional type upper beam string assembly, supporting assemblies, a first connecting node, a third connecting node and a fourth connecting node, the sectional type upper beam string assembly is formed by splicing a plurality of sections of upper beam strings through the first connecting node, and the supporting assemblies are arranged in a crossed mode and distributed below the upper beam string assembly. The supporting assemblies are connected through a third connecting node and hinged through a third connecting node, the intersection of the supporting assemblies is rotatably connected through a fourth connecting node, the angle of the intersection of the supporting assemblies can be adjusted through rotary connection, the two ends of the CFRP cable are connected with the two ends of the sectional upper chord beam assembly respectively, and the middle of the CFRP cable is connected with the fourth connecting node in a matched mode. According to the scheme, the laminated wood beams, the supporting rods and the CFRP cables are combined, prestress is applied to the CFRP cables to be introduced into the CFRP cable-laminated wood combined beam string structure, internal force distribution of the wood beams is adjusted, the peak value of bending moment in the beams is reduced, the application span of the wood beam structure is increased, and the bearing capacity of the structure is improved.
本发明公开了一种CFRP索‑胶合木组合张弦梁体系，包括CFRP索，分段式上弦梁组件，支撑组件，第一连接节点，第三连接节点，第四连接节点，分段式上弦梁组件是由多段上弦梁通过第一连接节点拼接构成，支撑组件交叉设置并分布于上弦梁组件下方，并通过第三连接节点进行铰接，支撑组件交叉处通过第四连连接节点进行可转动连接，通过转动连接可调节支撑组件交叉处角度的大小，CFRP索的两端分别与分段式上弦梁组件的两端进行连接，中部与第四连接点进行配合连接。本方案将胶合木梁、撑杆和CFRP索组合起来，通过给CFRP索施加预应力将预应力引入CFRP索‑胶合木组合张弦梁结构中，调整木梁内力分布，减小梁内弯矩峰值，增加木梁结构的应用跨度，提高结构的承载能力。
