Cast-in-place box girder movable formwork complete-set construction equipment and method thereof
The invention relates to the technical field of bridge construction, in particular to cast-in-place box girder movable formwork complete-set construction equipment and a method thereof.The cast-in-place box girder movable formwork complete-set construction equipment comprises a cast-in-place box girder, a movable formwork, a movable formwork bracket, a pier column, a portal crane, an electric hoist, a steel wire rope, a walking track, a reinforcing steel bar overall framework and a lifting tool construction device; when the integral reinforcing steel bar framework is poured into a concrete box girder, the manufacturing process of binding bottom plate reinforcing steel bars and web reinforcing steel bars, arranging prestressed steel beams and assembling the reinforcing steel bar framework of an inner mold can be carried out on the cast-in-place box girder at the same time; and the manufactured integral reinforcing steel bar framework is continuously and quickly conveyed into the outer formwork of the movable formwork, so that synchronous operation is realized, and the construction period of each hole can be shortened by about 5 days. Compared with a traditional construction technology, a gantry crane is not needed, so that the requirements for large span, large tonnage and high clearance are met, the problem that when pier studs are too high, the construction requirement cannot be met when a steel reinforcement framework is hoisted by a traditional gantry crane is solved, and meanwhile the method is also suitable for the situation that a gantry crane walking track cannot be arranged under a bridge floor in offshore construction and the like.
本发明涉及桥梁建造技术领域，具体涉及一种现浇箱梁移动模架成套施工设备及其方法，所述成套施工设备包括现浇箱梁、移动模架、移动模架托架、墩柱、门式吊机、电动葫芦、钢丝绳、行走轨道和钢筋整体骨架及吊具施工装置，当把钢筋整体骨架浇筑成混凝土箱梁时，可以同时在现浇箱梁上进行绑扎底板钢筋和腹板钢筋，布置预应力钢束以及拼装内模的钢筋骨架的制作过程，便于在移动模架过孔时，继续快速将制作好的钢筋整体骨架运送至移动模架的外模板内，从而实现了同步作业，每一孔的施工周期可缩短5天左右。相对于传统施工工艺，不需龙门吊，因此满足了大跨度、大吨位以及高净空的要求，解决了当墩柱过高时传统的龙门吊吊运钢筋骨架无法满足施工要求的问题，同时对于海上施工等桥面下无法设置龙门吊行走轨道的情况也同样适用。
