Fabricated hollow slab bridge and construction method thereof
The invention relates to the technical field of bridge construction, and discloses a fabricated hollow slab bridge and a construction method thereof. All the hollow slabs are transversely connected into a whole through the inter-slab connecting devices. Due to the arrangement of the middle cantilevers, the top surfaces of the middle cantilevers and the top surfaces of the hollow slabs jointly form a plane structure for pavement of the bridge deck structure and serve as a bottom die of a cast-in-place layer of the bridge deck structure. And then, a guardrail structure is cast on the top of the side cantilever beam in situ, and a bridge deck structure is cast on situ by taking the plane structure and the guardrail structure as templates, so that bridge deck construction is facilitated, and the effect of strengthening the connection between a guardrail and a bridge structure is achieved. The middle suspension beams are arranged on the upper half parts between the adjacent hollow slabs, and the inter-slab connecting devices are arranged on the lower half parts between the adjacent hollow slabs, so that hinge joint diseases existing in conventional hollow slabs are avoided; due to the combined action of the inter-plate connecting device arranged on the lower half part of the inter-plate and the wall surface structure cast in place on the plane structure, the transverse integrity and durability of the bridge plate are improved.
本发明涉及桥梁建设施工技术领域，公开了一种装配式空心板桥及其施工方法。利用板间连接装置将所有空心板横向连接成一个整体。由于设置中悬臂，中悬臂的顶面、以及空心板的顶面共同构成桥面结构铺装的平面结构，并作为桥面结构现浇层的底模。随后在边悬梁的顶部现场浇筑护栏结构，并以所述平面结构和护栏结构作为模板现场浇筑桥面结构，方便桥面施工并起到强化护栏与桥梁结构间联系的作用。在相邻空心板间的上半部分设置中悬梁、下半部分设置板间连接装置，避免了常规空心板存在的铰缝病害；由于板间下半部分设置有板间连接装置、以及现场浇筑在所述平面结构的墙面结构的共同作用，提升了桥板的横向整体性和耐久性。
