[0039] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0041] Example 1

[0042] like Figures 1 to 5 As shown, this embodiment provides a waterproof roof, which includes several boxes 1, a first waterproof layer 2, a second waterproof layer 3, and a third waterproof layer 4.

[0043] Several boxes 1 are independent but can be spliced ​​together to form a roof. Before the boxes 1 leave the factory, a first waterproof layer 2 is applied to the outer surface of the boxes 1. After the boxes 1 covered with the first waterproof layer 2 are transported to their destination, a second waterproof layer 3 is applied to the outer surface of at least two adjacent boxes 1, overlapping to waterproof the roof. The overlap positions of two adjacent second waterproof layers 3 are staggered from the joint positions of two adjacent first waterproof layers 2. A third waterproof layer 4 is applied to the outer surface of at least two adjacent boxes 1, overlapping with the overlap positions of two adjacent third waterproof layers 4.

[0044] The waterproof roof provided in this embodiment 1 is composed of independent box-shaped units 1 spliced ​​together. During transportation, the box-shaped units 1 can be disassembled into individual modules, facilitating transport. When constructing the roof, simply splicing the box-shaped units 1 together is very simple and quick. The first waterproof layer 2 helps prevent water from entering the box-shaped units 1 during transportation and roof construction, improving their durability. The joints between the first waterproof layers 2 are most prone to water seepage. Covering these joints with a second waterproof layer 3 prevents rainwater from flowing in through these areas. Furthermore, the second waterproof layer 3 is staggered from the joints of the first waterproof layer 2 to prevent rainwater from approaching these joints, thus improving the roof's waterproofness.

[0045] When the house needs to be moved from its original location to another, the second waterproof layer 3 can be cut open to disassemble the container 1 into independent modules for easy transport. It is not necessary to remove the second waterproof layer 3, as this will not affect its waterproofing effect on other parts. After the container 1 is reassembled, the third waterproof layer 4 is laid at the cut to prevent water from seeping in. This disassembly, relocation, and reassembly method is very fast. The second and third waterproof layers 3 and 4 respectively waterproof different areas, preventing a decrease in the roof's waterproofing after disassembly and relocation.

[0046] Example 2

[0047] This embodiment is a further improvement on embodiment 1, such as... Figures 1 to 10 As shown, the second waterproof layer 3 and the third waterproof layer 4 are made of thermoplastic polyolefin waterproof membrane. The long side overlap width of the second waterproof layer 3 is 120mm, and the short side overlap width is 80mm. It is connected to the housing 1 by fasteners at a distance of 30mm from the edge of the second waterproof layer 3. Specifically, the fasteners mentioned in this embodiment are preferably bolts 6.

[0048] In the waterproof roof provided in this embodiment, thermoplastic polyolefin waterproof membrane is used as the material for the second waterproof layer 3 and the third waterproof layer 4. This not only helps improve the waterproofness of the roof but also does not affect breathability, thus facilitating indoor air circulation. Limiting the overlap distance between the second waterproof layers 3 improves welding precision and helps enhance the stability and waterproofness of the joints of the second waterproof layers 3.

[0049] At the junction of the facade and plan of box 1, such as parapet walls, skylights, fan openings, and varying elevations, different structures are adopted depending on the specific circumstances. When the facade height exceeds 300mm or the area is located in a typhoon zone, a specific structure is used. Figure 6 or Figure 7 The structure, in Figure 7 In the middle, the second waterproof layer 3 extends from the vertical surface to the horizontal surface and is fixed to the horizontal surface by fasteners, and then the fourth waterproof layer 5 is covered on the fasteners; in Figure 6 In this structure, two second waterproof layers 3 are respectively installed on the vertical and horizontal surfaces. The horizontal second waterproof layer 3 overlaps the vertical second waterproof layer 3. Fasteners pass through both second waterproof layers 3 and are fixed horizontally. A fourth waterproof layer 5 covers the fasteners. When the vertical height is less than or equal to 300mm, a third waterproof layer is used. Figure 8 The structure consists of two layers of second waterproof layer 3 overlapping at the junction of the vertical and horizontal surfaces of the housing 1. The lower layer of second waterproof layer 3 on the horizontal surface is connected to the horizontal surface by fasteners, and the upper layer of second waterproof layer 3 on the vertical surface extends to the horizontal surface and covers the fasteners.

[0050] A second waterproof layer 3 is provided at the inside and outside corners. There may be only one second waterproof layer 3 at the inside and outside corners, such as...Figure 9 As shown, different second waterproof layers 3 can also be laid on the plane and vertical surfaces, such as... Figure 10 As shown, a fourth waterproof layer 5 is laid on the second waterproof layer 3 at the positions corresponding to the inside and outside corners. Specific construction methods are used for special locations such as the junction of the plane and the vertical surface, and inside and outside corners, which improves the waterproofing of these special locations.

[0051] Example 3

[0052] This embodiment provides a construction method for waterproof roofing, including the following steps:

[0053] The outer surface of the casing 1 is covered with a first waterproof layer 2 (such as...). Figure 2 As shown), the boxes 1 are spliced ​​together to form the roof;

[0054] A second waterproof layer 3 is applied to the outer surface of the first waterproof layer 2 of two adjacent boxes 1 (e.g., Figure 3 (as shown), and the overlapping position of two adjacent second waterproof layers 3 is staggered from the joint position between two adjacent first waterproof layers 2;

[0055] When the waterproof roof needs to be moved to another location, first cut the second waterproof layer 3 along the joint of the box body 1 (e.g., Figure 4 (as shown); after moving to the corresponding position, cover the outer surface of the second waterproof layer 3 with the third waterproof layer 4 (as shown). Figure 5 As shown in the figure, the overlapping positions of two adjacent third waterproof layers 4 are staggered from the overlapping positions of two adjacent second waterproof layers 3.

[0056] When the house needs to be moved from its original location to another, the second waterproof layer 3 can be cut open to disassemble the container 1 into independent modules for easy transport. It is not necessary to remove the second waterproof layer 3, as this will not affect its waterproofing effect on other parts. After the container 1 is reassembled, the third waterproof layer 4 is laid at the cut to prevent water from seeping in. This disassembly, relocation, and reassembly method is very fast. The second and third waterproof layers 3 and 4 respectively waterproof different areas, preventing a decrease in the roof's waterproofing after disassembly and relocation.

[0057] Example 4

[0058] This embodiment is a further improvement on embodiment 3. After laying the second waterproof layer 3, it is left to stand for 15-30 minutes before connecting adjacent second waterproof layers 3. This is to fully release the internal stress of the waterproof material and avoid wrinkling during welding.

[0059] The second waterproof layer 3 and the third waterproof layer 4 are connected by hot air welding, and the welding width is greater than or equal to 25 mm. The connection stability between the waterproof layers and the wind lifting resistance are improved.

[0060] When the third waterproof layer 4 is laid, a T-shaped joint is formed. The T-shaped joint is processed as follows: cutting processing is performed in a region with a radial distance of 15 cm from the T-shaped joint, the front end of the weld is cut into an inclined surface, and a circular waterproof layer with a diameter greater than or equal to 15 cm is welded to the T-shaped joint. A specific construction method is used for the T-shaped joint, which improves the waterproofness of the T-shaped joint.

[0061] Obviously, the above embodiments are only examples for clearly illustrating, and are not intended to limit the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments do not need to be exhausted, and the obvious changes or variations derived therefrom are still within the protection scope of the application.
