Adjustable large-span composite string truss assembling support
The invention discloses an adjustable large-span composite string truss assembling support. The technical problem that stress concentration is prone to being generated when a traditional assembling support is used for on-site construction, assembling and supporting of a large-span composite string truss is solved. Comprising a supporting frame, an upper chord member supporting mechanism arranged on the supporting frame and used for supporting an upper chord member of the composite string truss, and a lower chord member supporting mechanism arranged on the supporting frame and used for supporting a lower chord member of the composite string truss and capable of adjusting the elevation of the lower chord member. The support is small in specification and size, simple in structure and convenient to machine, the mounting efficiency of the assembled support can be effectively improved, the lower chord supporting mechanism used for supporting the lower chord of the composite string truss is supported through the hydraulic telescopic vertical rods, and the height can be adjusted; the supporting force is continuously provided for the lower chord member by adjusting the height of the hydraulic telescopic vertical rod, so that the technical problem that the assembling support cannot provide the supporting force for the lower chord member when the prestressed cable is tensioned on the ground is solved.
本发明公开了一种可调节式大跨度复合张弦桁架拼装支架，解决传统拼装支架在大跨度复合张弦桁架现场施工拼装支撑时易产生应力集中的技术问题。包括支撑架，设于支撑架上用于支撑复合张弦桁架上弦杆的上弦杆支撑机构，设于支撑架上用于支撑复合张弦桁架下弦杆并可调节自身标高的下弦杆支撑机构。本发明支架规格尺寸较少，结构简单，加工便利，可有效提高拼装支架的安装效率，用于支撑复合张弦桁架下弦杆的下弦杆支撑机构采用液压伸缩立杆进行支撑，可调节高度，当预应力拉索进行地面初张拉且下弦杆欲脱离胎架向上拱起，通过调节液压伸缩立杆高度持续为下弦杆提供支撑力，以解决预应力索进行地面张拉时拼装支架无法为下弦杆提供支撑力的技术问题。
