Prestressed cable net structural beam
The embodiment of the invention discloses a prestressed cable net structural beam, and relates to the technical field of cable net structures. The prestressed cable net structural beam comprises a cable truss mechanism and a plurality of supporting assemblies arranged at intervals in the first direction. The cable truss mechanism comprises at least four prestressed cables and a plurality of transverse stiffening truss structures, so that the rigidity of the prestressed cable net structural beam can be improved through the arrangement of the transverse stiffening truss structures, and particularly the rigidity of the middle parts of the prestressed cables is improved. Furthermore, connecting trusses located in the same transverse stiffening truss structure define a plane, and the area of each plane is gradually reduced from the side close to the corresponding supporting assembly to the side away from the corresponding supporting assembly, so that the rigidity of the prestressed cable net structural beam is further improved by changing the prestressing force of the prestressed cables at different positions, and the prestressed cable net structural beam has the characteristics of light self weight, high vertical and horizontal rigidity, high spanning capability and certain torsion resistance, and has a wide application prospect in structural engineering.
本发明实施例公开了一种预应力索网结构梁，涉及索网结构技术领域。该预应力索网结构梁包括索桁机构和多个沿第一方向间隔设置的支撑组件。索桁机构包括至少四个预应力索和多个横向加劲桁架结构，如此通过横向加劲桁架结构的设置能够提高预应力索网结构梁的刚度，尤其是提高预应力索中部的刚度。进一步地，位于同一横向加劲桁架结构中的各连接桁架围设形成平面，各平面的面积由靠近支撑组件一侧向远离支撑组件一侧逐渐减小，如此通过改变预应力索不同位置的预应力，进一步提高预应力索网结构梁的刚度，使得预应力索网结构梁具有自重轻、竖向和水平刚度大、跨越能力强且具备一定的抗扭能力的特点，在结构工程中具有广阔应用前景。
