Technical Field

[0001] The utility model belongs to the technical field of building formwork supporting structures, and in particular relates to a formwork protection bracket. Background Art

[0002] The formwork is a tool used for cast-in-place concrete construction. The main process of formwork construction is usually to set up the full frame - lay the wood - install the frame beam formwork - lay the rib beam bottom formwork - tie the frame beam reinforcement - draw the rib beam center line - fix the formwork - tie the rib beam and floor slab reinforcement - pour concrete.

[0003] The production of building formwork is inseparable from the technology of cast-in-place concrete lightweight floor. It is a technology that uses advanced reinforced concrete structure calculation software to calculate and analyze the stress distribution of the plate, arrange the built-in formwork in the most reasonable way in different stress distribution change areas and node position ranges, optimize the concrete stress section and reduce the deadweight, and obtain the minimum amount of steel bars used for safe and reasonable configuration, and form a good overall floor through on-site concrete pouring.

[0004] The formwork is an important formwork component to ensure concrete pouring. It is usually used in batches, and its shape and structure are directly related to the quality of building formation.

[0005] The problem with the prior art is that, due to their structural characteristics, mold shells are usually stored in vertical stacks. The piles of mold shells are mainly loaded onto operating vehicles by manpower, transferred by transfer vehicles, and then unloaded from the vehicles by manpower.
