Description

Technical Field

[0001] This utility model relates to a prefabricated cabin body and a prefabricated cabin, belonging to the technical field of devices for power supply or distribution. Background Technology

[0002] A prefabricated cabin is an integrated device in which the production, assembly, wiring, and debugging of primary and secondary electrical equipment are completed in the factory, and then transported as a whole to the construction site for installation on a prefabricated foundation.

[0003] Existing prefabricated cabins include a cabin body and equipment such as cabinets installed within the cabin body. For example, Chinese invention patent application CN119914109A discloses a prefabricated cabin body that includes a base and sidewalls fixed to the edge of the base. The sidewalls include a sidewall frame and outer wall panels, and also include a fireproof and heat-insulating layer located inside the sidewall frame. The sidewall frame includes columns, and the outer wall panels include multiple sequentially spliced ​​sealing module units. Adjacent sealing module units and columns are sealed and connected by a sealing butt joint structure.

[0004] Currently, the various sealing modules of the exterior wall panels are generally made of steel plates, which have poor corrosion resistance. When used in high salt spray environments, a series of anti-corrosion treatments are required to protect the surface of the steel plates, resulting in numerous and time-consuming processes. Furthermore, during the assembly and manufacturing of existing prefabricated cabins, the installation of the exterior wall panels and the fireproof and thermal insulation layers are carried out separately, involving many steps and affecting assembly efficiency. In addition, the weight of the steel plates contributes to the overall weight of the cabin, making it inconvenient for transportation and on-site installation. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated cabin body to solve the problems of existing prefabricated cabin bodies using steel plates for the outer wall panels, which require anti-corrosion treatment and separate installation of the steel plates and fireproof and heat-insulating layers, resulting in many procedures and long time consumption, as well as the problem that the large weight of the steel plates leads to the large weight of the cabin body, making it inconvenient for transportation and on-site installation; the purpose of this utility model is also to provide a prefabricated cabin to solve the above problems.

[0006] To achieve the above objectives, the prefabricated cabin body in this utility model adopts the following technical solution: The prefabricated cabin body includes a frame column and wall panels fixed to the frame column. The wall panels are prefabricated basalt composite wall panels. The basalt composite wall panels include an inner panel, an outer panel, and insulation material filled between the inner and outer panels. Both the inner and outer panels are made of basalt fiberboard.

[0007] The beneficial effects of the above technical solution are as follows: This utility model is an improved invention, which specifies that the wall panel is a basalt composite wall panel. The basalt composite wall panel includes an inner panel, an outer panel, and insulation material filled between the inner and outer panels. Both the inner and outer panels are made of basalt fiberboard. This allows for the prefabrication of the basalt composite wall panel, which can be installed as a whole during the assembly of the cabin without the need for a separate insulation layer, thus improving assembly efficiency. At the same time, basalt fiberboard has good corrosion resistance, eliminating the need for further anti-corrosion treatment, saving processes and time, and improving assembly efficiency. Furthermore, compared to steel plates, basalt fiberboard is lightweight, which can reduce the weight of the cabin and facilitate transportation and on-site installation.

[0008] Furthermore, the wall panel on one side of the cabin includes at least two stacked panels, each with a sealing structure connecting the inner and outer panels at both ends. The two adjacent panels are joined by a tenon and mortise joint.

[0009] Furthermore, a ring beam is fixed to the top of the frame column. There is a gap between the top surface of the uppermost segment plate and the bottom surface of the ring beam. This gap allows the uppermost segment plate to be inserted between the ring beam and the lower segment plate for connection. A U-shaped edge banding piece with the groove facing inward is inserted into the gap. The upper and lower side walls of the U-shaped edge banding piece contact the bottom surface of the ring beam and the top surface of the uppermost segment plate, respectively. The middle side wall of the U-shaped edge banding piece is vertically arranged and aligned with the outer side wall of the ring beam and the outer plate of the uppermost segment plate.

[0010] Furthermore, the joints between the U-shaped edge banding and the ring beam, and between the U-shaped edge banding and the uppermost segment plate, are coated with sealant.

[0011] Furthermore, the prefabricated cabin body also includes a shielding component that is fixed at the upper end to the outer wall of the ring beam and at the lower end to the outer plate of the uppermost segment plate, and completely covers the joint between the U-shaped edge sealing component and the ring beam, as well as the joint between the U-shaped edge sealing component and the uppermost segment plate.

[0012] Furthermore, the top of the uppermost segment plate is cut so that it can be inserted between the ring beam and the lower segment plate. A U-shaped sealing piece with the groove facing downward is inserted between the tops of the inner and outer plates of the uppermost segment plate. The U-shaped sealing piece constitutes the sealing structure of the uppermost segment plate.

[0013] Furthermore, the frame column includes a main structural component, which includes a U-shaped body with the slot facing outward and flanges extending in opposite directions from the left and right ends of the U-shaped body. The inner plate and the two flanges of the main structural component are fixed to the flanges by rivets.

[0014] Furthermore, the frame column also includes a sub-structural component fixed inside the U-shaped main body of the main structural component. The sub-structural component is U-shaped, with its left and right sidewalls contacting the left and right sidewalls of the U-shaped main body, respectively. The middle sidewall of the sub-structural component is aligned with the two flanges of the main structural component. There is sealant between the middle sidewall of the sub-structural component, the two flanges of the main structural component, and the inner plate.

[0015] Furthermore, the prefabricated cabin body is assembled from two or more sub-cabinets. Each sub-cabinet has U-shaped edge fittings installed on the left and right ends of the wall panels parallel to the assembly direction. The U-shaped edge fittings also wrap around the outermost frame column, and the U-shaped edge fittings of adjacent wall panels are joined and sealed.

[0016] To achieve the above objectives, the prefabricated cabin in this utility model adopts the following technical solution: The prefabricated cabin includes a cabin body and a cabinet installed inside the cabin body. The cabin body includes a frame column and wall panels fixed to the frame column. The wall panels are prefabricated basalt composite wall panels. The basalt composite wall panels include an inner panel, an outer panel, and insulation material filled between the inner and outer panels. Both the inner and outer panels are made of basalt fiberboard.

[0017] The beneficial effects of the above technical solution are as follows: This utility model is an improved invention, which specifies that the wall panel is a basalt composite wall panel. The basalt composite wall panel includes an inner panel, an outer panel, and insulation material filled between the inner and outer panels. Both the inner and outer panels are made of basalt fiberboard. This allows for the prefabrication of the basalt composite wall panel, which can be installed as a whole during the assembly of the cabin without the need for a separate insulation layer, thus improving assembly efficiency. At the same time, basalt fiberboard has good corrosion resistance, eliminating the need for further anti-corrosion treatment, saving processes and time, and improving assembly efficiency. Furthermore, compared to steel plates, basalt fiberboard is lightweight, which can reduce the weight of the cabin and facilitate transportation and on-site installation.

[0028] In view of the technical problems existing in the prior art, the basic concept of this utility model is to use prefabricated basalt composite wall panels. Basalt composite wall panels have both heat insulation and anti-corrosion properties, and are lightweight, which can save processes, improve assembly efficiency, and reduce the weight of the cabin.

[0029] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0030] The implementation method of the prefabricated cabin body in this utility model: like Figure 1 As shown, the prefabricated cabin in this embodiment is an independently manufactured complete cabin. The prefabricated cabin includes a base 1, a cabin frame fixed on the base 1, wall panels 3 installed on the sides of the cabin frame, and a top cover 4 installed on the top of the cabin frame. The cabin frame includes multiple frame columns 2 and ring beams 7 fixed to the top of the frame columns 2. Figure 5 and Figure 6 As shown in the figure, the top cover 4 is fixed on the ring beam 7.

[0031] Wall panel 3 is fixed to the frame columns 2. From the outside, wall panel 3 completely covers all the frame columns 2, meaning the frame columns 2 are concealed, resulting in a good consistency in the appearance of the cabin. It should be noted that... Figure 1 In order to show the frame column 2, part of the wall panel 3 was hidden.

[0032] Combination Figure 2 and Figure 3As shown, the wall panel 3 in this utility model is a prefabricated basalt composite wall panel. The basalt composite wall panel is made by molding basalt fiber and resin into a wall panel frame using a mold molding process. The interior has a hollow structure, and thermal insulation material 33 is filled in to enhance its thermal insulation performance. The wall panel frame includes an inner panel 31 and an outer panel 32. Both the inner panel 31 and the outer panel 32 are made of basalt fiberboard. The thermal insulation material 33 is filled between the inner and outer panels. Specifically, the thermal insulation material 33 can be rigid polyurethane foam or phenolic resin foam.

[0033] Therefore, the entire assembly of the cabin can be installed as a whole without the need for a separate insulation layer, which can improve assembly efficiency. At the same time, basalt fiberboard has good anti-corrosion properties, eliminating the need for additional anti-corrosion treatment, saving processes and time, and improving assembly efficiency. Furthermore, compared to steel plates, basalt fiberboard is lightweight, which can reduce the weight of the cabin and facilitate transportation and on-site installation.

[0034] In addition, the outer surface of the basalt composite wall panel (i.e. the outer surface of the outer panel 32) can be sprayed with paint or painted to ultimately form an integrated wall panel that combines thermal insulation and decorative effects.

[0035] Furthermore, the aforementioned wall panel frame also includes an intermediate stiffening plate 34 integrally connected between the inner panel 31 and the outer panel 32. The intermediate stiffening plate 34 can increase the structural strength of the basalt composite wall panel, and at the same time, it divides the interior of the wall panel into multiple hollow structures, each of which is filled with thermal insulation material 33.

[0036] Furthermore, considering the manufacturability of basalt composite wall panels, the wall panel framework produced by the mold forming process has a large length-to-width ratio, resulting in a single basalt composite wall panel having a long strip-like structure. Therefore, as... Figure 4 As shown, the wall panel 3 on one side of the cabin includes at least two stacked panels 30. Each panel 30 is a basalt composite wall panel. The length of each panel 30 satisfies the total length of the side of the cabin it is located on. That is, for the wall panel 3 on one side of the cabin, the panels 30 are only stacked in the width direction (cabin height direction) and not in the length direction.

[0037] Each segment panel 30 is an independent basalt composite wall panel with consistent length and width. Each segment panel 30 has sealing structures at both its top and bottom ends, connecting the inner and outer panels to prevent the internal insulation material 33 from detaching. Specifically, the wall panel frame, manufactured using a mold-forming process, has closed structures at both ends, meaning the sealing structures at both ends are integrally formed with the inner and outer panels. In reality, sealing structures are also required at both ends along the length of the segment panel to prevent the insulation material 33 from being exposed; however, these sealing structures are separately installed.

[0038] The two adjacent panels 30 are joined together by mortise and tenon joints, such as... Figure 2 As shown, the closed structure at the upper end of each segment plate 30 forms a protrusion 35, and the closed structure at the lower end forms a groove 36. The groove 36 of the upper segment plate is engaged with the protrusion 35 of the lower segment plate, thereby realizing the insertion between two adjacent segment plates 30.

[0039] When installing wall panel 3, first place the bottommost panel 30 on base 1. Apply sealant to the joint between the bottom of the bottommost panel 30 and base 1 to ensure a seal between the bottommost panel 30 and base 1 and to ensure the stability of the bottommost panel 30. Then, stack each panel 30 sequentially from bottom to top. Adjacent panels 30 are engaged by protrusions 35 and grooves 36. Before placing the top panel 30, apply a high-quality weather-resistant sealant evenly inside the groove 36 of the top panel 30 or outside the protrusion 35 of the bottom panel 30. This sealant can fully fill the 0.5-2mm installation gap. During installation, pressure is used to evenly fill the internal gaps with sealant, forming a continuous and complete internal sealing layer. Subsequently, apply a supplementary sealant to the external joint of the top and bottom panels 30, ultimately forming a triple sealing system consisting of an internal sealant layer, tenon and mortise mechanical interlocking, and an external sealant layer.

[0040] Meanwhile, each panel 30 is fixed to two or more frame columns 2. Therefore, when placing each panel 30, it is necessary to ensure that the panel 30 is flush with and fixed to the frame columns 2. During construction, sealant is first evenly applied to the surface of the frame columns 2. The adhesive and filling properties of the sealant are used to tightly bond the wall panel to the column, effectively compensating for the installation gaps between them and ensuring a perfect fit between the wall panel and the column. Subsequently, mechanical reinforcement is carried out from the interior side of the cabin using rivets 6. This ensures the stability and durability of the connection points and cleverly conceals all fasteners through the double-layer wall panel structure design, maintaining a clean and rivet-free visual effect on the exterior facade of the cabin, ultimately forming a wall system that combines structural strength and aesthetic performance.

[0041] Specifically, such as Figure 3 and Figure 4 As shown, the frame column 2 includes a main structural member 21, which includes a U-shaped body with the groove facing outwards and flanges 211 extending in opposite directions from the left and right ends of the U-shaped body. The inner panel 31 of each segment panel 30 is fixed to the two flanges 211 of the main structural member 21 using rivets 6. Before placing the segment panel 30, sealant is applied to both flanges 211. Before the sealant cures, the inner panel 31 is fixed to the flanges 211 using rivets 6. The structural form of the main structural member 21 ensures both the structural strength of the column and meets the requirements for the adhesion and fixation of the wall panels.

[0042] Furthermore, the frame column 2 also includes a sub-structure 22 fixed inside the U-shaped main body of the main structural member 21. The sub-structure 22 is U-shaped, and its left and right side walls are in contact with the left and right side walls of the U-shaped main body, respectively. That is, the sub-structure 22 and the main structural member 21 are interlocked and fixed by adhesive or welding to form a rectangular tube structure, which enhances the structural strength of the frame column 2.

[0043] The middle sidewall of the sub-structural component 22 aligns with the two flanges 211 of the main structural component 21. The middle sidewall of the sub-structural component 22 is also fitted to the inner panel 31 of each segment panel 30, increasing the contact area between the frame column 2 and the wall panel. Therefore, before placing each segment panel 30, sealant is evenly applied to the middle sidewall of the sub-structural component 22. This sealant compensates for the installation gaps between the frame column 2 and the wall panel, ensuring a perfect fit between the wall panel and the column. This prevents unevenness on the sides of the column and wall panel due to processing precision issues, which could result in a loose fit between the wall panel and the column. Of course, the sealant also serves a fixing function, enhancing the fixation effect between the wall panel and the column.

[0044] Since the basalt composite wall panels are prefabricated, the width (vertical and vertical height) of each segment panel 30 is consistent. The height of the prefabricated cabin also has corresponding design requirements. Therefore, when placing the last segment panel 30 (i.e. the top segment panel), if there is not enough remaining space, the top segment panel needs to be cut reasonably according to the cabin height and tenon size to facilitate the installation of the top segment panel.

[0045] Specifically, such as Figure 5 and Figure 6 As shown, there is a gap between the top surface of the uppermost segment plate and the bottom surface of the ring beam 7 (the ring beam 7 is a rectangular tube). This gap allows the uppermost segment plate to insert between the ring beam 7 and the lower segment plate for connection. The state shown in the figure is after the top of the uppermost segment plate has been cut off; otherwise, the vertical height of the uppermost segment plate would be too large to insert between the ring beam 7 and the lower segment plate. After the uppermost segment plate inserts between the ring beam 7 and the lower segment plate, it moves downwards and inserts into the lower segment plate, thus creating a gap between the uppermost segment plate and the ring beam 7.

[0046] In other embodiments, even if the uppermost segment plate is not cut, it can still be inserted between the ring beam 7 and the lower segment plate, but after it is moved down and inserted into the lower segment plate, there will still be a gap between it and the ring beam 7.

[0047] Of course, for the top panel after cutting and installation, the internal insulation material 33 must not be exposed. Therefore, a U-shaped sealing piece 37 with its groove facing downwards is inserted between the tops of the inner and outer panels of the top panel. The top surface of the U-shaped sealing piece 37 is flush with the top surfaces of the inner and outer panels. The U-shaped sealing piece 37 forms the sealing structure at the top of the top panel. The sealing structure at the bottom of the top panel and the sealing structures at the top and bottom of each of the other panels are all integrally formed closed structures using a mold. To ensure stability, the U-shaped sealing piece 37 can be bonded and fixed to the inner and outer panels.

[0048] Of course, the gap between the topmost segment plate and the ring beam 7 cannot be exposed. Therefore, a U-shaped edge banding 8 with the groove facing inward is inserted in the gap. The upper and lower side walls of the U-shaped edge banding 8 are in contact with the bottom surface of the ring beam 7 and the top surface of the topmost segment plate (including the top surface of the outer panel 32 and the top surface of the U-shaped edge banding 37), respectively. The middle side wall of the U-shaped edge banding 8 is arranged vertically and aligned with the outer side wall of the ring beam 7 and the outer panel 32 of the topmost segment plate. That is, the outer side of the ring beam 7 is flush with the outer side of the entire wall panel.

[0049] To ensure airtightness, sealant 9 is applied to the joints between the U-shaped edge banding 8 and the ring beam 7, and to the joints between the U-shaped edge banding 8 and the uppermost segment plate. Figure 6 (The sealant is not visible in the middle). Of course, the sealant 9 can also bond and fix the U-shaped edge sealing piece 8 to the ring beam 7 and the top segment plate, ensuring the overall stability of the cabin. This sealing mechanism not only ensures the sealing effect during the installation process, but also provides reliable waterproof protection for the cabin throughout its entire life cycle, effectively coping with the sealing challenges brought about by various environmental factors.

[0050] In addition, the prefabricated cabin body also includes a shielding component 10, which is fixed at the upper end to the outer wall of the ring beam 7 and at the lower end to the outer plate 32 of the uppermost segment plate, and completely covers the joint between the U-shaped edge sealing component 8 and the ring beam 7, as well as the joint between the U-shaped edge sealing component 8 and the uppermost segment plate. This provides secondary protection for the sealant 9, and at the same time, the U-shaped edge sealing component 8 is not visible from the outside, resulting in a better appearance.

[0051] In this embodiment, the U-shaped sealing member 37, the U-shaped edge sealing member 8, and the blocking member 10 are all metal parts, and all are long strip-shaped components with their length direction consistent with the length direction of the wall panel. The blocking member 10 is a plate-shaped component with a slight bulge in the middle to avoid obstructing the sealant 9. The upper edge of the blocking member 10 is attached to the outer wall of the ring beam 7 and fixed to the outer wall of the ring beam 7 by bolts or rivets. The lower edge of the blocking member 10 is attached to the outer panel 32 and bonded to the outer panel 32 by sealant.

[0052] In addition, such as Figure 3 , Figure 5 and Figure 6As shown, the cabin frame also includes reinforcing connectors 5 welded and fixed between two adjacent frame columns 2. The reinforcing connectors 5 are L-shaped, with their horizontal sides flush with the top of the frame columns 2, and can jointly support and fix the ring beam 7. The vertical side of the reinforcing connectors 5 is attached to the inner plate 31 of the uppermost segment plate and is fixedly connected to the inner plate 31 by rivets 6, thereby strengthening the fixed connection between the uppermost segment plate and the cabin frame.

[0053] like Figure 6 As shown, the vertical edge of the reinforcing connector 5 corresponds to the side wall of the U-shaped sealing member 37 that fits against the inner plate 31 in a direction perpendicular to the inner plate 31, and the inner plate 31 is sandwiched between the two. Specifically, the bottom end of the vertical edge of the reinforcing connector 5 is flush with the bottom end of the side wall of the U-shaped sealing member 37, so the rivets 6 fixed on the reinforcing connector 5 and the inner plate 31 actually pass through the side wall of the U-shaped sealing member 37, realizing the connection between the three, making the fixation between the U-shaped sealing member 37 and the uppermost segment plate more secure, and at the same time, the side wall of the U-shaped sealing member 37 also acts as an inner pad.

[0054] It should be noted that before installing the aforementioned rivets 6, rivet holes must be pre-drilled at the installation locations.

[0055] like Figure 7 As shown, the prefabricated cabin in Example 2 is assembled from two or more sub-cabins. Each sub-cabin is manufactured separately and assembled on-site after transportation. Since each sub-cabin includes a base 1, a cabin frame, wall panels 3, and a top cover 4, the base 1, cabin frame, wall panels 3, and top cover 4 need to be connected on-site. Because the interiors of each sub-cabin are connected after connection, the wall panels 3 at both ends of the overall cabin length direction do not need to be connected; the original sub-cabin wall panels can be retained. However, the wall panels 3 at both ends of the width direction need to be connected.

[0056] Specifically, such as Figure 8 As shown, each compartment has U-shaped edging pieces 11 installed at both ends of the wall panels 3 (i.e., the wall panels located at both ends of the width direction of the overall compartment) parallel to the assembly direction (i.e., the length direction of the overall compartment). The U-shaped edging pieces 11 also cover the outermost frame columns 2, enhancing protection during transportation. Before the adjacent two wall panels 3 are joined, sealant is applied to the outer surface of the U-shaped edging pieces 11 or sealing strips are pasted to enhance the sealing performance at the junction. Finally, gap compensation pieces 12 are used to structurally seal the gaps at the junction. The gap compensation pieces 12 have a T-shaped cross-section, with one part inserted into the gap at the junction and the remaining part located outside the two adjacent wall panels 3 and in contact with the outer surfaces of the two side wall panels 3. Other installation processes are the same as in Example 1 and will not be repeated here.

[0057] In summary, the base 1, frame, and top cover 4 of the prefabricated cabin in this invention are all steel structures, while the wall panels 3 are made of basalt composite wall panels. These basalt composite wall panels integrate insulation and decoration, eliminating the need for a separate insulation layer, greatly simplifying the cabin assembly process, improving assembly efficiency, and saving labor costs. Simultaneously, the cabin achieves a lightweight design. Due to the high strength and low density of basalt fiber, the weight of the prefabricated cabin walls made from basalt fiber is reduced by more than 0.5 tons per 100 square meters compared to a steel structure cabin. This design enhances low-carbon and environmental protection goals and saves energy consumption during cabin hoisting, transportation, and construction.

[0058] In other embodiments of the prefabricated cabin body: the base, cabin frame and top cover of the prefabricated cabin body can also be made of basalt fiber to further reduce the weight of the cabin body.

[0059] In other embodiments of the prefabricated cabin body: For a prefabricated cabin body assembled from two or more sub-cabinets, the left and right ends of the wall panels of each sub-cabinet parallel to the assembly direction may no longer be fitted with U-shaped edge fittings, but instead directly connected using the sealing fittings at the ends of the wall panels themselves.

[0060] In other embodiments of the prefabricated cabin body: the frame columns may only include the main structural components and no longer include the sub-structural components. In this case, the two flanges of the main structural components and the inner panel of the wall panel are coated with sealant.

[0061] In other embodiments of the prefabricated cabin body: the frame columns can also be made of I-beams or H-beams. In this case, one flange of the I-beam or H-beam is attached to the inner panel of the wall panel and fixed by rivets. Of course, sealant can be applied between the flange and the inner panel of the wall panel.

[0062] In other embodiments of the prefabricated cabin body: the frame columns and wall panels can be fixed only by adhesive bonding, without the need for rivets. In this case, the frame columns can be main structural components including a U-shaped body and two flanges, or they can be I-beams, H-beams, U-shaped channel steel, or rectangular tubes.

[0063] In other embodiments of the prefabricated cabin body: when the uppermost segment plate can be inserted between the ring beam and the lower segment plate without cutting, the uppermost segment plate is an independent and complete structure, eliminating the need for U-shaped sealing parts.

[0064] In other embodiments of the prefabricated cabin body: the shielding parts may not be required, and the joints between the U-shaped edge banding and the ring beam, and the joints between the U-shaped edge banding and the uppermost segment plate may be directly exposed.

[0065] In other embodiments of the prefabricated cabin body: when the U-shaped sealing strip is tightly fitted, the joint between the U-shaped sealing strip and the ring beam, and the joint between the U-shaped sealing strip and the uppermost segment plate, do not need to be sealed with sealant.

[0066] In other embodiments of the prefabricated cabin body: the upper closed structure of the segment plate can form a groove, and the lower closed structure can form a protrusion. The upper and lower segment plates are also connected by protrusions and grooves.

[0067] In other embodiments of the prefabricated cabin body: the upper and lower ends of the segment panels may no longer have protrusions and grooves, that is, the upper and lower segment panels are no longer connected by mortise and tenon structures. For example, the upper and lower ends of the segment panels are both flat, and the upper segment panel is placed directly on the lower segment panel. At this time, the size of the uppermost segment panel, whether cut or not, just matches the remaining space. After the uppermost segment panel is inserted between the ring beam and the lower segment panel, the top surface of the uppermost segment panel is in close contact with the bottom surface of the ring beam, and the bottom surface of the uppermost segment panel is in close contact with the top surface of the lower segment panel. There is no need to set up U-shaped edge sealing parts, and of course, there is no need to apply glue or fix the shielding parts.

[0068] In other embodiments of the prefabricated cabin body: depending on the specific manufacturing process, if the vertical height of a single wall panel can meet the height of the cabin body, it is not necessary to assemble the wall panel on one side of the cabin body by stacking multiple sub-panels. The wall panel on one side of the cabin body is a single wall panel.

[0069] The implementation method of the prefabricated cabin in this utility model is as follows: the prefabricated cabin includes a cabin body and a cabinet installed inside the cabin body. The cabin body is the same as the prefabricated cabin body in the above implementation method, and will not be repeated here.

[0070] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
