[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] A prefabricated heated shed structure for core tube construction in high-altitude and cold regions, such as Figure 1 , Figure 2 , Figure 3 As shown, it includes an outer frame 1, a corner reinforcement frame 2, a core tube frame 3, and a roof purlin 4. The outer frame 1 is erected on the outdoor ground, and the core tube frame 3 is erected in the recessed area of ​​the core tube area.

[0027] like Figure 4 As shown, the outer frame 1 consists of two rows of first uprights 11, several first horizontal bars 12, and several first diagonal braces 13. The first uprights 11 are arranged at equal intervals, the first horizontal bars 12 are arranged at equal heights, and the first diagonal braces 13 are arranged along the diagonal. Heating devices 5 are arranged along the first uprights 11 of the outer frame 1. The first uprights 11 of the outer frame 1 extend 0.5m below the ground level, and the heating devices 5 are simultaneously buried 0.5m below the ground level. This ensures that the outer frame can withstand wind loads and also allows the heating devices 5 to heat the ground surface, avoiding temperature differences between hot and cold concrete at the core tube pouring interface.

[0028] like Figure 4 As shown, the corner reinforcement frame 2 is located at the four corners of the outer frame 1, and is divided into two extended spans along the longitudinal and transverse directions, serving as a way to reinforce the corners and maintain the stability of the greenhouse. The corner reinforcement frame 2 includes several second uprights 21, and several second horizontal bars 22 are connected between the second uprights 21 from top to bottom. The second horizontal bars 22 are fixedly connected to the first horizontal bars 12 at the corners of the outer frame 1.

[0029] like Figure 5 As shown, the core tube frame 3 consists of two rows of third uprights 31, several third horizontal bars 32, and several third diagonal braces 33. The third uprights 31 are arranged at equal intervals, the third horizontal bars 32 are arranged at equal heights, and the third diagonal braces 33 are arranged along the diagonal. Heating devices 5 are arranged along the third uprights 31 of the core tube frame 3 to ensure that the temperature of the casting area meets the specified requirements.

[0030] like Figure 1 , Figure 2 , Figure 3 As shown, the roof purlin 4 connects the outer frame 1 and the core tube frame 3, and connects the interior of the core tube frame 3 to form a statically indeterminate structure, which ensures the stability of the overall structure while being easy to assemble.

[0031] like Figure 2 , Figure 3 As shown, the heating device 5 is arranged on the inner and outer sides of the outer frame 1 and the core tube frame 3 respectively. The heating device on the outer frame 1 serves to insulate the core tube area and heat the connection interface, so as to ensure the pouring temperature and avoid cold bridges at the pouring point.

[0032] The outer frame 1, core tube frame 3, and roof purlin 4 can all be erected using steel pipe scaffolding commonly used on the construction site, and the components are connected by fasteners.

[0033] This invention protects the winter construction area by constructing a core tube frame 3 and an outer frame 1 in the core tube area and the outer area, connected with roof purlins 4. The roof purlins 1 and the double-layer frame form a statically indeterminate system, which, together with the corner reinforcement frame 2, ensures the stability of the greenhouse in windy areas. The heating device 5 of the greenhouse is set up based on the frame uprights, and the heating device of the outer frame 1 extends below the ground level to increase the surface temperature and avoid large temperature differences at the interface. The entire frame is constructed using steel pipe scaffolding commonly used on construction sites, and the components are connected by fasteners, which is easy to assemble, safe and efficient, ensuring the temperature requirements for core tube construction in high-altitude and cold regions and improving the quality of construction.

[0034] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
