Prefabricated assembly type steel-concrete mixed cantilever structure system for widening road and construction method
The invention discloses a prefabricated assembly type steel-concrete mixed cantilever structure system for widening a road, and relates to the field of steel-concrete mixed structures in road structures. The system comprises a cantilever beam which comprises a first-section concrete precast block, a third-section concrete precast block, a second-section concrete precast block and a plurality of steel member joint devices. The steel member joint devices are arranged at the two ends of the second-section concrete precast block; the first-section concrete precast block is connected with the steel member joint device at one end of the second-section concrete precast block, and the third-section concrete precast block is connected with the steel member joint device at the other end of the second-section concrete precast block. The cantilever beam is cut, partitioned and prefabricated, the weight of each partitioned block can be controlled according to needs, and the problem that a storage site, transportation equipment and hoisting equipment are difficult to select due to the fact that the weight and the size are too large is solved. The invention further relates to a construction method of the prefabricated assembly type steel-concrete mixed cantilever structure system for widening the road.
本发明公开了一种拓宽道路的预制装配式钢混混合悬挑结构体系，涉及道路结构中的钢混混合结构领域。它包括悬挑横梁，悬挑横梁包括第一段混凝土预制块、第三段混凝土预制块、第二段混凝土预制块、多个钢构件接头装置；第二段混凝土预制块两端均设置有钢构件接头装置；第一段混凝土预制块与第二段混凝土预制块一端的钢构件接头装置连接，第三段混凝土预制块与第二段混凝土预制块另一端的钢构件接头装置连接。本发明对悬挑横梁进行切割分块预制，分块后每块重量可根据需要进行控制，解决了因重量和尺寸过大带来的存储场地、运输设备、吊装设备选择困难的问题。本发明还涉及这种拓宽道路的预制装配式钢混混合悬挑结构体系的施工方法。
