The invention discloses a formwork supporting system for a large-span open-web sandwich plate structure and a construction method. The formwork supporting system comprises a supporting frame. The supporting frame comprises a lower rib formwork supporting part, a shear key formwork supporting part, upper rib side plate supporting parts, an upper rib bottom plate supporting part and thin plate formwork supporting parts. A lower rib formwork is supported by the lower rib formwork supporting part. A shear key formwork is supported by the shear key formwork supporting part. Upper rib side plate formworks are supported by the upper rib side plate supporting parts. An upper rib bottom plate formwork is supported by the upper rib bottom plate supporting part. Thin plate formworks are supported by the thin plate formwork supporting parts. A concrete pouring port capable of pouring concrete into the lower rib formwork and the shear key formwork is formed in the upper rib bottom plate supporting part. The formwork supporting system for the large-span open-web sandwich plate structure has the beneficial effects that a construction platform does not need to be erected separately, the problems that the lower rib is inconvenient to construct, and the construction period is long are solved effectively, and convenience and rapidness of concrete pouring of a open-web sandwich plate are guaranteed.
Description
technical field [0001] The invention relates to the technical field of construction of large-span fasting sandwich slab structures, in particular to a formwork support system and construction method for long-span fasting sandwich slab structures. Background technique [0002] The reconstruction and expansion project of old cadre activity facilities in Guizhou Province is located in Zhaiji Road, Guiyang City, Guizhou Province, adjacent to the provincial government compound, belonging to the urban area of Guiyang City. ㎡, building height 35.8m. The project adopts the hollow sandwich panel structure, which is a large-span non-prestressed structure, the beam body is hollow, and the construction of the bracket formwork is complicated. The above-ground structure adopts the fasting sandwich panel structure, and three kinds of fasting sandwich panel forms are used comprehensively: 1) Orthogonal inclined concrete hollow sandwich panel structure with a span of 23.4m, which is the f...
