[0003] The support mode generally adopted by the concrete formwork support frame for the top plate formwork is that the concrete formwork support frame comprises a plurality of support units, each support unit is provided with a plurality of support uprights, each support upright extends from the ground to the top plate formwork, and the top plate formwork is directly supported by the plurality of support uprights. In this way, a large number of support uprights need to be arranged in each support unit, and the distance between the plurality of support units needs to be kept within 1.3 m to ensure the support strength of the formwork support frame for the top plate formwork.

[0038] The template support frame in the related technical means directly supports the top plate template through a plurality of support stands, and the distance between a plurality of support units and the distance between two support stands of each support unit need to be kept within 1.3 m to ensure the support strength of the template support frame to the top plate template. In this way, a plurality of support stands each of which needs to be set in a large number are required for each support unit. The use of the support stands is large, and the transportation cost and material cost are high. Increasing the distance between the two support stands can reduce the amount of the support stands, but if the distance between the two support stands is directly increased, the support strength of the support unit of the template support frame will not be enough.

[0039] In the related technology, each support unit includes three support stands and two cross rods, and the uppermost part between the two adjacent support stands is connected by a cross rod to ensure the stability of the structure between the two adjacent support stands through the cross rod. However, if the distance between the two support stands is increased, the connection of the two support stands by the cross rod cannot well ensure the structural stability and support strength of the support stands.

[0040] The template support frame of the present application ensures the strength of the template support frame by arranging a truss connecting frame between two vertical rods. In an embodiment of the present application, a template support frame is provided, which comprises a plurality of support units, each of which comprises two support vertical rods, and the plurality of support units are arranged at intervals; each support unit further comprises a first support truss, which comprises a truss support rod and a truss connecting frame connected to each other, the truss connecting frame is a polygonal structure, the truss connecting frame is connected to the two support vertical rods, and the truss support rod and the two support vertical rods are both used for supporting a top plate template.

[0041] Through the above arrangement, the truss connecting frame replaces the original cross rod, and the truss support rod replaces the middle support vertical rod of the original three support vertical rods, so that no extra support vertical rod needs to be arranged between the two support vertical rods of the support unit, the spacing of the two support vertical rods can be increased, the number of support vertical rods of each support unit can be reduced, and when supporting the top plate template, the pressure can be shared by the multiple "sides" of the truss connecting frame, so that the support strength of the support unit is ensured while the number of support vertical rods is reduced, and each support unit is provided with a first support truss, which further reduces the number of support vertical rods and ensures the support strength of the plurality of support units, thereby ensuring the support strength of the entire template support frame.

[0042] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The features in the following embodiments and examples can be combined with each other without conflict.

[0044] Through the above arrangement, the truss support rod 10 and the support vertical rod 100 jointly support the top plate template. When supporting the top plate template, no extra support vertical rod 100 needs to be arranged between the two support vertical rods 100 of the support unit 1, the number of support vertical rods 100 of each support unit 1 can be reduced, and the pressure is shared by the multiple “sides” of the truss connecting frame 20, so that the support strength of the support unit 1 is ensured while the number of support vertical rods 100 is reduced, and each support unit 1 of the present application is provided with a first support truss 2, which further reduces the number of support vertical rods 100 while ensuring the support strength of multiple support units 1, thereby ensuring the support strength of the entire template support frame.

[0054] Preferably, the truss connecting frame 20 is symmetrically arranged with a first preset axis as the axis of symmetry, and the truss connecting frame 20 is symmetrically arranged with a second preset axis as the axis of symmetry. In this way, the truss connecting frame 20 forms an up-down symmetric and left-right symmetric structure, further making the stress distribution of the truss connecting frame 20 uniform, thereby preventing stress concentration of the truss connecting frame 20 from causing fracture.
