Novel large-span plate truss composite structure and construction method thereof
The invention discloses a novel large-span plate truss composite structure and a construction method thereof. The structural form can be used for a large-span bridge structure and a large-span publicarch building structure, with the structure, construction templates and scaffolds can be saved, during construction, the steel structure part is firstly installed, concrete is directly cast in place on the steel structure, formwork erecting and scaffolding are not needed in the construction period of the structure, the steel structure part is directly equivalent to a concrete formwork, so construction cost is saved, after the concrete structure reaches the strength, at the moment, the steel structure and the concrete slab on the steel structure form a combined structure to jointly bear a liveload, concrete stress and steel structure tension, compared with a concrete structure, the combination can save concrete materials and can be made into a structure with a larger span, compared with apure steel structure, the structure can further save steel and can be made into a structure with a larger span.
本发明公开了一种新型大跨板桁组合结构及其施工方法。本发明的结构形式可用于大跨桥梁结构以及大跨公共拱建筑结构，此结构可以节省施工模板和脚手架，在施工期间先安装钢结构部分，然后直接在钢结构上面现浇混凝土，此结构施工期间不用支模和脚手架，钢结构部分直接相当于混凝土模板，这样节省施工成本，当混凝土结构达到强度以后，此时钢结构又和上面混凝土板组成组合结构，共同承受活荷载，混凝土受压，钢结构受拉，相对于混凝土结构来说，这种组合又可以节约混凝土材料，又能够做跨度更大的结构，相对于纯钢结构来说，此种结构也能节约钢材，跨度能够做得更大。
