[0019] The utility model is further described below in conjunction with the embodiments. The description of the following embodiments is only used to help understand the utility model. It should be pointed out that for ordinary people in this technical field, the utility model can also be modified in some ways without departing from the principle of the utility model, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.

[0020] As an example, Figure 1 and Figure 2As shown, the canopy platform concrete punching belt shaping support construction device is used to support and fix the wooden square formwork on both sides of the concrete punching belt to cast the concrete punching belt. It includes: an inner fixing rod 1, a cross bar 2, an adjustable screw rod 3 and an outer fixing rod 4. The inner fixing rod 1 is fixed on the platform concrete, and the outer fixing rod 4 is arranged outside the pouring position of the concrete punching belt. The inner fixing rod 1 and the outer fixing rod 4 are fixed by the cross bar 2. The steel frame is formed by welding to connect and fix the various structures, so as to ensure that the various structures are firmly connected and accurately positioned.

[0021] A fixing anchor bolt 9 is provided on the platform concrete outside the inner fixing rod 1, and a wedge is inserted between the fixing anchor bolt 9 and the inner fixing rod 1, so as to realize the fixing and binding of the inner end of the device and enhance the overall stability and binding force of the device.

[0022] An adjustable screw rod 3 is vertically provided on the cross bar 2, which is used to fix the wooden formwork on the inner side of the concrete impact belt and press it tightly against the platform concrete; two bottom supports 8 are fixed under the cross bar 2, and the outer fixing rod 4 and the bottom support 8 are arranged at the top of the concrete side wall of the platform. The bottom support 8, the inner fixing rod 1, the cross bar 2 and the outer fixing rod 4 are all L50*4mm angle steels, and the top of the bottom support 8 and the bottom edge of the cross bar 2 are welded and connected, and the two bottom supports 8 are arranged facing each other.

[0023] The bottom support 8 is arranged between the wooden formwork on the inner side of the concrete impact belt and the inner fixed rod 1, which does not affect the formwork and pouring of the concrete impact belt. The bottom ends of the two bottom supports 8 are supported on the platform concrete, ensuring the horizontality of the cross bar 2 and the verticality of the inner fixed rod 1 and the outer fixed rod 4.

[0024] The inner fixing rod 1 and the bottom support 8 are at the same height, the bottom elevation of the outer fixing rod 4 is lower than the inner fixing rod 1 and the bottom support 8, and the bottom end of the outer fixing rod 4 is horizontally connected with a bottom support 7, which is a 50mm*50mm*4mm steel square tube.
