DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all embodiments.

[0035] In the related art, during construction, a support system and a top plate template system need to be set up. The support system not only supports the top plate template system, but also supports the beams, steel bars and other structures of the building.

[0036] In the related art, the support frame directly supports the keel rod through multiple support vertical rods. Each support vertical rod extends along the ground to the position of the keel rod. In this way, each support unit needs to use multiple support vertical rods, and a large number of support vertical rods need to be set up to ensure the support strength of the support frame on the keel rod and the wood template, thereby resulting in a large number of keel rods. The support vertical rods and the keel rods used in this arrangement form have a large amount of material, and the transportation cost and the material cost are high.

[0037] The embodiments of the present application provide a top plate template support system, which comprises a template component, a keel rod group and a support frame. The support frame supports the keel rod group, and the keel rod group supports the template component. The support frame comprises multiple support units. Each support unit comprises two support vertical rods and a first support truss. Each first support truss comprises a polygonal truss connecting frame and a truss support rod. The truss support rod and the truss connecting frame are connected to each other. The truss connecting frame is a polygonal structure. The truss connecting frame is connected to the two support vertical rods. The truss support rod and the two support vertical rods are used to support the top plate template.

[0038] Through the above arrangement, when the support frame supports the joist rod group, the pressure is shared by the multiple "sides" of the truss connecting frame, thereby improving the carrying capacity of the support unit. The two support vertical rods of the support unit do not need to be arranged again, reducing the number of support vertical rods of each support unit, increasing the support spacing of the two support vertical rods of each support unit, and reducing the number of joist rod groups while ensuring the support strength of the support frame. Each support unit is provided with a first support truss, which improves the carrying capacity of each support unit, thereby increasing the support spacing between the multiple support units of the support frame while ensuring the carrying capacity of the entire support frame. Further, the number of support vertical rods is reduced. Due to the reduction in the number of joist rod groups and support vertical rods, the turnover efficiency of the support system can be improved, and the labor intensity is reduced.

[0039] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The features of the following embodiments and examples can be combined with each other without conflict.

[0040] Figure 1 is a schematic diagram of the overall structure of an array of multiple support units of an embodiment of the roof formwork support system of the present application. Figure 2 is a schematic diagram of the overall structure of another embodiment of the roof formwork support system of the present application.

[0041] Please refer to Figure 1 and Figure 2 The present application provides a roof formwork support system, which comprises a formwork component 1, a joist rod group 2 and a support frame 3. The joist rod group 2 is located below the formwork component 1 and supports the formwork component 1. The support frame 3 is arranged below the joist rod group 2 and supports the joist rod group 2. The support frame 3 comprises multiple support units 30, which are arranged at intervals. Each support unit 30 comprises two support vertical rods 31 and a first support truss 32. The first support truss 32 comprises a truss support rod 320 and a truss connecting frame 321. The truss connecting frame 321 has a polygonal structure and is connected to the two support vertical rods 31. The truss support rod 320 is connected to the truss connecting frame 321 and is arranged parallel to the support vertical rods 31.

[0042] When the support frame 3 supports the keel rod group 2 through the above arrangement, the pressure is shared by the multiple "edges" of the truss connection frame, thereby improving the support strength of the support unit 30. No support vertical rod 31 is required between the two support vertical rods 31 of the support unit 30, reducing the number of support vertical rods 31 of each support unit 30. In addition, each support unit 30 is provided with a first support truss 32, which improves the support strength of each support unit 30, thereby improving the support strength of the entire support frame 3. While ensuring the support strength, the support spacing between the multiple support units 30 of the support frame 3 can be increased, further reducing the number of support vertical rods, and thus reducing the number of keel rod groups 2. Due to the reduction in the number of keel rod groups 2 and support vertical rods 31, the construction efficiency and turnover efficiency of the support system can be improved, and the labor intensity can be reduced.

[0043] In the related art, each support unit includes three support uprights and two cross bars, and the tops of two adjacent support uprights are connected by cross bars to ensure the structural stability between the two adjacent support uprights. However, if the distance between the two support uprights is increased, only connecting the two support uprights with cross bars cannot well ensure the structural stability and support strength of the support uprights.

In this way, each supporting unit 30 only needs to be provided with two supporting rods 31, and the pressure is shared by multiple "edges" of the truss connecting frame 321, so that the spacing between the supporting rods 31 of each supporting unit 30 can be increased.
