Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figure 1-8 , this embodiment provides a prefabricated cabin thermal insulation structure, including a cabin body 100, a cabin thermal insulation mechanism 200, and a manhole thermal insulation mechanism 300;

[0031] The cabin body 100 includes a cabin bottom plate 110, a cabin side plate 120 fixedly connected to the cabin bottom plate 110, and a cabin top plate 130 fixedly connected to the upper end of the cabin side plate 120. It can be understood that the cabin body 100 is a hollow structure;

[0032] The cabin thermal insulation mechanism 200 includes a fixing component 210 and a thermal insulation material 220. The fixing component 210 includes a channel steel 211 fixedly arranged on the lower surface of the cabin bottom plate 110, a bottom fixing plate 212 fixedly arranged on the lower surface of the channel steel 211, a square tube 213 fixedly arranged on the lower surface of the cabin top plate 130, and a top fixing plate 214 fixedly arranged on the lower surface of the square tube 213. The thermal insulation material 220 is filled between the cabin bottom plate 110 and the bottom fixing plate 212 and between the cabin top plate 130 and the top fixing plate 214. A plurality of positioning angle steels 215 are fixedly arranged on the inner surface of the cabin side plate 120, and ribbed plates 216 are inserted between adjacent positioning angle steels 215, and the ribbed plates 216 are filled with the thermal insulation material 220;

[0033] It can be understood that the cabin thermal insulation mechanism 200 fills the thermal insulation material 220 inside the top, outside the bottom, and inside the four sides of the cabin body 100, and uses the top fixing plate 214 and the bottom fixing plate 212 to fix the thermal insulation materials 220 at the top and bottom respectively, and uses the positioning angle steel 215 to fix the thermal insulation materials 220 at the four sides of the side;

[0034] The manhole thermal insulation mechanism 300 includes reserved holes 310 correspondingly opened on the cabin floor 110, the bottom fixing plate 212, the top fixing plate 214, and the cabin roof 130. An outer wall plate 320 of the manhole is fixedly arranged on one side of the cabin roof 130 close to the reserved hole 310. The thermal insulation material 220 is filled on one side of the outer wall plate 320 of the manhole close to the reserved hole 310, and a manhole fixing plate 330 is arranged on one side of the thermal insulation material 220 close to the reserved hole 310;

[0035] The number of the reserved holes 310 can be set according to actual needs. In this embodiment, 2 reserved holes 310 are set. The thermal insulation structures on both sides of the reserved hole 310 are to form a filling cavity using the outer wall plate 320 of the manhole and the manhole fixing plate 330, and fill it with the thermal insulation material 220, which improves the thermal insulation effect of the manhole and makes the opening flat and beautiful.

[0036] In this embodiment, the manhole fixing plate 330 is L-shaped, one end is fixedly connected to the outer wall plate 320 of the manhole, and one end is fixedly connected to the cabin roof 130. It can be understood that the L-shaped manhole fixing plate 330 is convenient to fix and has a supporting effect, making the opening flat and beautiful.

[0037] In this embodiment, the manhole thermal insulation mechanism 300 further includes a manhole top sealing plate 340. The outer wall plate 320 of the manhole extends to cover all the reserved holes 310. The thermal insulation material 220 is filled between the manhole top sealing plate 340 and the outer wall plate 320 of the manhole. A wire routing hole 350 is opened on one side of the outer wall plate 320 of the manhole. It can be understood that the outer wall plate 320 of the manhole protrudes a rectangular structure at the opening, and the wire routing hole 350 is opened on the side of the rectangle. When the top does not need to be a through hole and only wire routing is required, this manhole thermal insulation method can be used. The lines that need to be connected to the outside in the prefabricated cabin can pass through the wire routing hole 350, making the lines neat and not scattered, and improving the thermal insulation effect near the manhole;

[0038] In this implementation, two different thermal insulation methods are set for the two reserved holes 310. One is the through hole type, and the other is the above-mentioned wire routing hole 350 method. Of course, the thermal insulation methods of the two reserved holes 310 can be selected according to needs.

[0039] In this embodiment, the thermal insulation material 220 is rock wool. It can be understood that other filling materials with thermal insulation effects can also be used.

[0040] In this embodiment, multiple square tubes 213, positioning angle steels 215, and channel steels 211 are provided. It can be understood that multiple of them are arranged in parallel, which play the roles of connection, fixation, and support, and reinforce the structure of the cabin body 100.

[0041] In this embodiment, the installation positions of the square tubes 213, positioning angle steels 215, and channel steels 211 are parallel to the cabin bottom plate 110.

[0042] In this embodiment, the cabin thermal insulation mechanism 200 further includes support angle steels 217 fixedly arranged at both ends of the top fixing plate 214, and the other ends of the support angle steels 217 are fixedly connected to the cabin side plate 120, playing the role of connection and fixation.

[0043] In this embodiment, the outer layers of the bottom fixing plate 212 and the top fixing plate 214 are galvanized. Galvanization has the effects of anti-corrosion and anti-rusting, making the service life of the prefabricated cabin thermal insulation structure longer.

[0044] Before the installation of the thermal insulation structure of the prefabricated cabin, laser cutting reserved holes 310 are made on the cabin bottom plate 110, bottom fixing plate 212, top fixing plate 214, and cabin top plate 130. During installation, the cabin body 100 is inverted, and the four corners are padded to leave a height difference at the top. After laying the rock wool, the top fixing plate 214 is installed sequentially from one end to the other end, and the top fixing plate 214 is fixed to the cabin body 100. When encountering the position of the reserved hole 310, a manhole fixing plate 330 is installed; the installation of the bottom thermal insulation structure is the same as that of the top; on the side, the positioning angle steel 215 is fixedly connected to the cabin side plate 120, the ribbed plates are filled with rock wool, and after the filling is completed, they are inserted between adjacent positioning angle steels 215 in sequence and fixed pairwise. The last ribbed plate 216 is made according to the on-site reserved size.

[0045] The fixed connection in this embodiment is welding, and other fixing methods can also be used.

[0046] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
