Concrete pouring formwork for outer wrapping bottom plate of arch bridge and construction method thereof
The invention relates to the technical field of construction of large-span concrete arch bridges, in particular to a concrete pouring formwork for an outer wrapping bottom plate of an arch bridge anda construction method thereof. The outer wrapping bottom plate concrete pouring formwork comprises a plurality of stiff skeleton sections with bottom formworks, and the stiff skeleton sections are fixedly connected in sequence. Each stiff skeleton section with the bottom formwork comprises a stiff skeleton section, a bottom formwork and a connecting plate, and the bottom formwork and the connecting plate correspond to the stiff skeleton section. In each stiff skeleton section with the bottom formwork, the lower chord of each stiff skeleton section is fixedly connected with the corresponding bottom formwork through the corresponding connecting plate. The invention further discloses a construction method of the concrete pouring formwork for the outer wrapping bottom plate of the arch bridge.According to the concrete pouring formwork for the outer wrapping bottom plate, a rigid mold can be provided for concrete pouring of the outer wrapping bottom plate of a stiff framework, the weight of the formwork and the weight of a formwork auxiliary structure can be reduced, the windward area is reduced, the engineering construction period can be shortened, and the engineering safety degree can be improved.
本发明涉及大跨度混凝土拱桥施工建造技术领域，具体涉及一种用于拱桥的外包底板混凝土浇筑模板及其施工方法；所述外包底板混凝土浇筑模板包括若干个依次固定连接的带底模劲性骨架段；带底模劲性骨架段均包括劲性骨架节段，以及与所述劲性骨架节段相对应的底模和连接板；且单个带底模劲性骨架段中，劲性骨架节段的下弦杆通过对应的连接板与对应的底模固定连接；本发明还公开用于拱桥的外包底板混凝土浇筑模板施工方法。本发明的外包底板混凝土浇筑模板能够为劲性骨架的外包底板混凝土浇筑提供刚性模具，能够减小模板自身以及模板辅助结构的重量，减小迎风面积，还能够缩短工程工期和提高工程安全度。
