Lossless assembly type steel box-concrete composite beam cantilever casting formwork supporting structure
The invention discloses a lossless assembly type steel box-concrete composite beam cantilever casting formwork supporting structure. The lossless assembly type steel box-concrete composite beam cantilever casting formwork supporting structure comprises a steel box, a connecting plate, stiffening columns, a grating plate, a supporting plate, an anti-disengaging device, a jacking rod and angle braces. The connecting plates are arranged in transverse gaps of shear nails of the steel box top plate, and the two sides of the connecting plates are fixedly connected with the stiffening columns and the grating plates. One side of the stiffening column abuts against the inner side of a steel box web below the cantilever, and the lower portion of the stiffening column is supported on a steel box bottom plate. The supporting plate abuts against the outer side of a steel box web below the cantilever, and the lower portion of the supporting plate is supported on the cantilever section of a steel box bottom plate. The jacking rods provide certain pre-pressure for attachment of the supporting plates and the steel box webs, and the jacking rods and the angle braces jointly support the grating plates and construction loads above the grating plates. The anti-falling device is fixed to the supporting plate and the steel box bottom plate and used for preventing the supporting plate from falling off. The cantilever formwork supporting structure is built through the original geometric structure of the steel box, the lossless assembly technology is adopted, a full framing does not need to be built, and the advantages of being safe, reliable, economical and efficient are achieved.
本发明公开一种无损装配式钢箱‑混凝土组合梁悬臂浇筑模板支撑结构，包括钢箱、连接板、加劲柱、格栅板、支撑板、防脱装置、顶升杆和角撑。连接板布置于钢箱顶板剪力钉横排间隙，两侧与加劲柱和格栅板固定连接；加劲柱一侧紧靠于悬臂下方的钢箱腹板内侧，其下方支撑于钢箱底板；支撑板紧靠于悬臂下方的钢箱腹板外侧，其下方支撑于钢箱底板悬挑段；顶升杆为支撑板和钢箱腹板的贴合提供一定的预压力，并与角撑共同支撑格栅板及其上方施工荷载；防脱装置固定在支撑板和钢箱底板，用于防止支撑板脱落。本发明利用钢箱原有几何构造搭建悬臂模板支撑结构，采用无损装配工艺，且无需搭设满堂支架，具有安全可靠和经济高效的优势。
