[0002] In the construction industry, "formwork" usually refers to a formwork and scaffolding system used to support the concrete construction process. This formwork system can be used to build large structures such as high-rise buildings, bridges, and water conservancy projects. The umbrella-shaped curved concrete structure formwork system usually consists of support rods, beams, formwork, etc., which can provide a stable support structure to facilitate the pouring and curing of concrete. This system plays a vital role in construction and can ensure safety and efficiency during the construction process.

[0003] In the project, it is necessary to build an umbrella-shaped curved concrete structure building with a high outer periphery and a concave middle, which transitions from the outer periphery to a circular arc in the middle. This is a non-standard building. Currently, there is no formwork or formwork for producing this building on the market, so a construction tool with a simple structure and convenient construction is needed. Summary of the invention

[0006] Through a plurality of vertical support plates on an umbrella-shaped curved concrete structure formwork, these plates are arranged divergently from the center to the surroundings. The outer sides of their upper ends are higher than the inner sides, presenting an appearance of an inward arc transition. On the vertical support plates, a plurality of frames are fixed along the periphery of the umbrella-shaped curved concrete structure formwork to the middle at intervals. A support frame is arranged under each frame, and the upper end of the support frame abuts against the lower end of the frame to vertically support the plurality of frames, and a plurality of cover plates are laid on the frame along the arc surface to reduce the gap between the vertical support plate and the frame. This design can meet the needs of building a building with a high periphery, a concave middle, and a transition from the periphery to the middle arc, and has the characteristics of simple structure and easy production.

[0007] Preferably, the frame comprises four cross bars connected end to end.

[0008] Preferably, a plurality of placement grooves are arranged at intervals along the arc surface on the vertical support plate, the placement grooves are recessed toward the normal of the arc surface, the bottoms thereof abut against the lower end surfaces of the cross bars, and the two sides thereof abut against the two sides of the cross bars.

[0009] Preferably, the support frame includes connecting plates located on both sides of the bottom of the vertical support plate, and the connecting plates are fixed with a number of vertically upward support columns that are consistent with the placement slots. The support columns are located on one side of the placement slot, and their upper end surfaces are against the lower end surface of the cross bar.
