[0017] In order to make the patent purposes, technical solutions and advantages of the present application more clear, the present application will be further described in detail below in combination with the drawings and examples.

[0018] In order to illustrate the technical solutions of the present application, the following will be described by specific examples.

[0019] In order to facilitate the description, only the parts related to the embodiments of the present application are shown.

[0020] In combination with Figures 2-5As shown, the caisson formwork removal platform comprises a pair of form removal operation platforms 1, a pair of gantry hangers 2 is arranged between the form removal operation platforms 1, and the form removal operation platforms 1 are outwardly formed with up-and-down walking platforms 3 opposite to the gantry hangers 2, the bottom of the form removal operation platforms 1 is provided with inner support frames, the bottom of the up-and-down walking platforms 3 is provided with outer support frames, the bottom of the outer support frames is mounted on the inner support frames, and a circle of guardrails 6 is arranged on the form removal operation platforms 1 and the up-and-down walking platforms 3.

[0021] The caisson formwork removal platform is an important technology in the field of building technology, and has great significance in urban construction and municipal engineering. The traditional caisson concrete high connection construction often adopts the form turnover method. After the caisson construction is completed, the operator can use the removal platform to complete the removal of the concrete formwork.

[0022] As shown in the drawings, Figure 1 As shown in the drawings, As shown in the drawings, the caisson formwork removal platform comprises a pair of form removal operation platforms 1, a pair of gantry hangers 2 is arranged between the form removal operation platforms 1, and the form removal operation platforms 1 are outwardly formed with up-and-down walking platforms 3 opposite to the gantry hangers 2, the bottom of the form removal operation platforms 1 is provided with inner support frames, the bottom of the up-and-down walking platforms 3 is provided with outer support frames, the bottom of the outer support frames is mounted on the inner support frames, and a circle of guardrails 6 is arranged on the form removal operation platforms 1 and the up-and-down walking platforms 3.

[0023] In the structure, the bottom of the form removal operation platform is provided with an inner support frame, the bottom of the up-and-down walking platform is provided with an outer support frame, the form removal operation platform and the up-and-down walking platform are connected and jointly constitute a working platform. The inner support frame and the outer support frame make the overall structure of the working platform more solid and reliable, so that the workers can walk stably and safely on the working platform.

[0024] As a preferred structure, as shown in the drawings, Figures 2-3 The gantry hanger 2 comprises a pair of channel steels 7, vertical ladders 8 and connecting frames 9 are arranged from the outside to the inside at both ends of the channel steels 7, and the bottom of the vertical ladders 8 and the bottom of the connecting frames 9 are fixed on the same side form removal operation platform 1 respectively. The width of the up-and-down walking platform is twice the width of the vertical ladder 8, which does not affect the personnel climbing the vertical ladder and the path communication between the up-and-down walking platform and the form removal operation platform. Moreover, the vertical ladder 8 and the connecting frame 9 are arranged at intervals, and a passage is reserved in the middle, which does not affect the movement of personnel on the form removal operation platform.

[0025] In this structure, each vertical ladder on the demolding platform has an outward-facing walking platform. Workers can only walk normally on the demolding platform after descending the ladder to the corresponding walking platform. By providing these walking platforms, the space of the demolding platform is widened, facilitating workers' ascent and descent. Furthermore, the bottoms of the vertical ladders and connecting frames are installed on both sides of the demolding platform, ensuring that they do not obstruct workers' movement during demolding.

[0026] In addition, a reinforcing bar 10 is provided around the edge of both the demolding platform 1 and the upper and lower walking platforms 3, and the bottom of the guardrail 6 is installed on the reinforcing bar 10. During demolding operations on the platform, the guardrail prevents workers from falling off. The reinforcing bar further strengthens and reinforces the entire platform structure.

[0027] As a specific structure, such as Figures 2-4 The inner support frame includes a base rod 41, with several connecting rods 42 facing upwards on the base rod 41. Each connecting rod 42 on the base rod 41 has an inner support rod 43 facing inwards. The tops of the connecting rods 42 and the inner support rods 43 are respectively fixed to the two sides of the demolding platform 1. The outer support frame includes multiple outer support rods 5 installed on the base rod 41. The tops of the outer support rods 5 are fixed to the upper and lower walking platforms 3.

[0028] In this structure, the inner and outer support frames respectively support the demolding platform and the vertical walking platform. The support from these frames makes the demolding platform and the vertical walking platform more robust and reliable, resulting in greater stability and safety for workers walking on them.

[0029] A reinforcing rod 11 is provided on the demolding platform 1 between the connecting rod 42 and the inner support rod 43. Each set of reinforcing rods 11, connecting rods 42, and inner support rods 43 has a triangular structure, so that the inner support frame can effectively support the demolding platform. Similarly, a fixing rod 12 is also provided on the vertical walking platform 3 between the connecting rod 42 and the outer support rod 5. The connecting rod 42, outer support rod 5, and fixing rod 12 also have a triangular structure. The triangular support design improves the structural stability.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
