[0003] A formwork support structure for casting a dome-shaped roof is disclosed in publication number CN215054439U, which reduces the investment cost of the formwork and the effect of indoor ceiling plain concrete, shortens the construction period and the manufacturing time of the special formwork.

[0004] However, this formwork support structure for pouring a dome-shaped roof has the following disadvantages:

[0005] (1) During rainy and snowy weather, the load-bearing capacity of the roof increases, resulting in a larger load on the arch support. In addition, there is a lack of extended support structures on both sides of the arch support, which makes the overall seismic performance and rigidity insufficient, and collapse occurs;

[0006] (2) The interior of the arched support lacks an adjustable support structure, which causes the structural parts inside the support to swing, thereby reducing stability. Utility Model Content
