Fabricated steel bridge structure with string tensioning mechanism
The invention relates to an assembly type steel bridge structure with string structures. The problems that an existing steel bridge is small in span, heavy in weight, long in assembling time, large in finished bridge deflection when the span is large and the like are solved. The structure is composed of a main body structure and a string tensioning mechanism, and the main body structure is formed by connecting a standard truss and a high-shear-resistance truss in a pin joint mode. The string tensioning mechanism is composed of a supporting frame and a steel pull rod and arranged at the bottom of the body structure, one end of the steel pull rod is fixed to the end of the body structure, the other end of the steel pull rod is fixed to the lower end of the supporting frame, and the upper end of the supporting frame is connected with the bottom face of the body structure to support the body structure. The fabricated steel bridge is high in spanning capacity and light in component weight, can be quickly assembled and erected, can be used as an emergency temporary project for quick rescue, and can also be used as a fabricated steel bridge for conventional construction and post-war and post-disaster reconstruction projects. According to the invention, small and medium span and large span coverage application can be realized, the storage and maintenance are convenient, and the applicability is good.
本发明涉及一种带张弦机构的装配式钢桥结构。为解决现有钢桥跨度小，重量重、拼装时间长，跨径较大时成桥挠度大等等的问题。本发明由主体结构和张弦机构组成，主体结构的标准桁架和高抗剪桁架销接连接而成。张弦机构由支撑架和钢拉杆组成，设置在主体结构底部，钢拉杆一端固定在主体结构的端部，另一端固定在支撑架下端，支撑架上端与主体结构底面连接，支撑主体结构。本发明跨越能力强，构件重量轻，能够快速拼装架设，同时既可作为快速抢险的应急临时性工程，又可作为常规建设及战后、灾后重建工程的装配式钢桥。本发明可实现中小跨径及大跨径覆盖应用，方便储备和维养，具有良好的适用性。
