Cast-in-place box girder edge protection structure and construction method
The invention discloses a cast-in-place box girder edge protection structure and a construction method, the cast-in-place box girder edge protection structure comprises a bearing beam and cantilever formworks, the cantilever formworks are located on the two sides of the bearing beam, a plurality of vertical supporting rods and inclined supporting rods are arranged between the cantilever formworks and the bearing beam, the cantilever formworks are provided with guardrail structures, and the guardrail structures are connected with the bearing beam. The guardrail structure comprises a flange template connected with the cantilever template, a plurality of handrails are arranged on the flange template, and a connecting square timber is arranged at the interval of a plurality of handrails. A cantilever structure support is fully utilized as a bearing structure of the guardrail and is combined with cast-in-place box girder construction, and a guardrail protection structure and cast-in-place box girder overall construction are combined and integrated. The guardrail structure is supported only on the top face of the cast-in-place box girder through the cantilever. After being impacted, the guardrails are mutually counteracted through self structures, so that the influence of horizontal force on the lower bracket is avoided, and the safety is better.
本申请公开了一种现浇箱梁临边防护结构及施工方法，包括承重梁、悬臂模板，所述悬臂模板位于所述承重梁的两侧，所述悬臂模板与所述承重梁之间设有数根竖向支撑杆和斜向支撑杆，所述悬臂模板上设有护栏结构，所述护栏结构包括与悬臂模板连接的翼缘模板、所述翼缘模板上设置若干根栏杆，每间隔数个栏杆设有一个连接方木。充分利用悬臂结构支撑作为护栏的承载结构，并与现浇箱梁施工相结合，将护栏防护结构与现浇箱梁整体施工相结合，融为一体。只在现浇箱梁顶面利用悬臂支撑护栏结构。护栏受冲击后通过自身结构相互抵消，对下部支架无水平力的影响，安全性更好。
