Abstract
Description
Technical Field
[0001] This utility model belongs to the field of prefabricated cabins, specifically relating to a top cover drainage structure for spliced prefabricated cabins. Background Technology
[0002] Prefabricated cabins are spliced during use, and the splicing surfaces are prone to water leakage, especially the splicing surfaces of the top cover. Therefore, properly handling the water leakage problem at the splicing surfaces of the top cover is a prerequisite for ensuring that the equipment inside the prefabricated cabin is not affected.
[0003] For the splicing surface of the single-slope roof, drainage is currently achieved through a single structure of waterproof folded edge and cover plate to prevent water leakage. However, if the rain is too heavy and cannot be drained in time, the accumulated water will drip along the splicing surface into the prefabricated cabin, affecting the equipment inside the cabin. Utility Model Content

[0016] An inverted U-shaped cover plate with its opening facing vertically downwards, one end of which is fixed to the first C-shaped component and the other end of which is fixed to the second C-shaped component;
[0017] The inverted U-shaped cover plate simultaneously seals the first C-shaped component and the second C-shaped component.
[0018] Furthermore, the inverted U-shaped cover plate simultaneously seals the first C-shaped component and the second C-shaped component through a sealing gasket.
[0019] Preferably, the first C-shaped component has a horizontal long side, a horizontal short side, and a vertical side. Both ends of the vertical side are fixed to the horizontal long side and the horizontal short side. The end of the horizontal long side is fixed to the vertical sidewall perpendicular to the plane at the top of the top cover. The horizontal short side corresponds to the vertical sidewall perpendicular to the plane at the top of the top cover. The vertical side is parallel to the vertical sidewall perpendicular to the plane at the top of the top cover.

[0032] 1. Because this utility model consists of a first waterproof structure, a second waterproof structure, and a third waterproof structure forming a three-layer waterproof structure, and the first waterproof structure is a roof tile stacking structure, the drainage capacity of this drainage structure is improved. Specifically, the joint between the high and low planes of the roof is constructed using the first waterproof structure, i.e., the roof tile stacking structure, with the high point pressing down on the low point, ensuring that water flows away along the slope. Specifically, a diversion plate is installed on the high plane of the roof, a water-retaining eaves are installed on the low plane of the roof, and a guide plate is installed below the diversion plate, with the guide plate pressing down on the water-retaining eaves. The structure features a sloped guide plate with drip edges to prevent rainwater from flowing back. The two components are covered by an inverted U-shaped cover plate, forming a second layer of waterproofing. When excessive rainwater cannot flow through the first layer and enters the second layer, the water is drained out of the prefabricated cabin through the opening in the second layer. Through the third layer of waterproofing, when too much rainwater accumulates and cannot flow through the second layer, the accumulated water drips along the two drip plates into the collection trough, and then flows through the drain pipe to the outside of the prefabricated cabin roof, thus preventing water from entering the prefabricated cabin and protecting the equipment inside.

[0045] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following embodiments are described in detail with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.
[0046] This utility model involves installing a drainage structure in the gap between two separate prefabricated compartments. This gap needs to be sealed using the outer components of this drainage structure (except for the notch), creating a channel inside the two separate prefabricated compartments and inside the sealed gap. This channel allows for actions such as wiring and door opening. The specific drainage structure is configured as follows:
[0047] like Figure 1 , 6 As shown in Figure -10, a drainage structure for a prefabricated modular cabin roof is provided. The prefabricated cabin roof has a pre-defined high plane 1 and a low plane 2, with the high plane 1 being higher than the low plane 2. The direction from the high plane 1 to the low plane 2 is defined as the slope direction A. The drainage structure includes...
[0048] The diversion plate 3 has one end fixed to the plane 1 at the top of the top cover (specifically, it is welded, and the diversion plate 3 and the plane 1 at the top of the top cover are made of the same material), and the other end extends along the slope direction A, and has a downward bending part 31 for the diversion plate.
[0049] A water-retaining eave 4, one end of which is fixed to the lower plane 2 of the roof (specifically, by welding, and the water-retaining eave 4 and the lower plane 2 of the roof are made of the same material), and as... Figure 2As shown, one end of the water-retaining eaves 4 is fixed to a vertical surface perpendicular to the plane 2 at the bottom of the roof. Its upper end extends vertically upward and is bent to form a horizontal part 41 of the water-retaining eaves. The horizontal part 41 of the water-retaining eaves is parallel to the bottom plane 2 of the roof.
[0050] The guide plate 5 has one end fixed to the top of the plane 2 at the lower part of the roof, and the other end extends vertically upward and is bent to form a horizontal section 51. The horizontal section 51 extends upward in the opposite direction of the slope A. The horizontal section 41 of the water-retaining eaves is fixed to the horizontal section 51 of the guide plate (specifically, it is welded, and the horizontal section 41 of the water-retaining eaves and the horizontal section 51 of the guide plate are made of the same material). The horizontal section 51 of the guide plate has an upward bending section 511. The downward bending section 31 of the guide plate cooperates with the upward bending section 511 of the horizontal section of the guide plate to form a roof tile stacking structure. A drip edge 52 is formed at the bend between the vertically upward extension of the guide plate 5 and the horizontal section 51 of the guide plate 5, i.e. Figure 3 As shown; the above structure forms the first waterproof structure. The purpose is to use this first waterproof structure at the splicing joint between the high plane 1 and the low plane 2 of the roof in the direction of slope A, that is, the roof tile stacking structure, with the high point pressing down on the low point, to ensure that the water will flow away with the slope; that is, a diversion plate 3 is set at the high plane 1 of the roof, a water-blocking eave 4 is set at the low plane 2 of the roof, a guide plate 3 is set below the diversion plate 2, the guide plate 3 is pressed above the water-blocking eave 4, the guide plate 3 has a certain slope, and a drip edge 52 is set to ensure that rainwater will not flow back.
[0051] As another embodiment, such as Figure 11 As shown, the horizontal part 51 of the guide plate does not have an upward bending section 511. Instead, the upper surface of the horizontal part 51 of the guide plate directly contacts the downward bending part 31 of the guide plate to form a roof tile stacking structure.
[0052] The diversion plate 3 has a lateral baffle plate 32 on the side near the high plane 1 of the top cover.
[0053] The other two ends of the guide plate 5 have guide plate bending portions 52, and each guide plate bending portion 52 wraps around the guide plate 3.
[0054] like Figure 2 As shown, the drainage structure also includes,
[0055] Two C-shaped parts 6, namely the first C-shaped part 61 and the second C-shaped part 62, are installed at one end on the vertical side wall perpendicular to the plane 1 at the high point of the top cover (specifically, by welding, and the first C-shaped part 61 and the vertical side wall perpendicular to the plane 1 at the high point of the top cover are made of the same material), and are located below the diversion plate 3. One end of the second C-shaped part 62 is installed on the vertical side wall perpendicular to the plane 2 at the low point of the top cover (specifically, by welding, and the second C-shaped part 62 and the vertical side wall perpendicular to the plane 2 at the low point of the top cover are made of the same material), and is located below the water-retaining eaves 4.
[0056] The inverted U-shaped cover plate 7 has its opening vertically downward, and one end of it is fixed to the first C-shaped part 61, and the other end is fixed to the second C-shaped part 62;
[0057] The inverted U-shaped cover plate 7 seals the first C-shaped part 61 and the second C-shaped part 62 simultaneously through the sealing gasket;
[0058] The two C-shaped components 6 and the inverted U-shaped cover plate 7 are all located inside the prefabricated cabin to enhance aesthetics and concealment.
[0059] The first C-shaped component 61 has a horizontal long side 611, a horizontal short side 612, and a vertical side 613. Both ends of the vertical side 613 are fixed to the horizontal long side 611 and the horizontal short side 612. The end of the horizontal long side 611 is fixed to the vertical side wall perpendicular to the plane 1 at the top of the top cover (specifically, by welding, and the horizontal long side 611 and the vertical side wall perpendicular to the plane 1 at the top of the top cover are made of the same material). The horizontal short side 612 corresponds to the vertical side wall perpendicular to the plane 1 at the top of the top cover, and the vertical side 613 is parallel to the vertical side wall perpendicular to the plane 1 at the top of the top cover.
[0060] It should be noted that the shape of the second C-shaped part 62 is the same as that of the first C-shaped part 61, and it is fixed (welded) to the vertical side wall perpendicular to the plane 2 at the bottom of the top cover in the same way.
[0061] One end of the inverted U-shaped cover plate 7 is located on the horizontal short side 612 (specifically, the inverted U-shaped cover plate 7 directly rests on the upper surface of the horizontal short side 612), and both the horizontal short side 612 and the vertical side 613 are located inside the inverted U-shaped cover plate 7; the purpose is to form a second waterproof structure by setting a first C-shaped component 61 below the drainage plate 3 at the high plane 1 of the top cover, and setting a second C-shaped component 62 below the water-retaining eaves 4 at the low plane 2 of the top cover, with the two C-shaped components 6 covered by the inverted U-shaped cover plate 7; when rainwater is too heavy to flow away through the first waterproof structure and flows into the second waterproof structure, the rainwater is discharged outside the prefabricated compartment through the gap 14 where the second waterproof structure is located (it should be noted that, as Figure 8The notch 14 shown is the area enclosed by the vertical sidewall perpendicular to the plane 1 at the top of the top cover, the horizontal long side 611, and the vertical surface of the inverted U-shaped cover plate 7. This area is opened on the prefabricated cabin along the frontal view direction.
[0062] A U-shaped or C-shaped guide plate support frame 8 (specifically welded, and the inverted U-shaped cover plate 7 and the guide plate support frame 8 are made of the same material) is fixed between the upper surface of the inverted U-shaped cover plate 7 and the lower surface of the guide plate 5. The purpose is to support the guide plate 5 and make the guide plate 5 contact the guide plate 3, thereby ensuring the sealing effect between the two.
[0063] like Figure 3 As shown, the drainage structure also includes,
[0064] Two drip plates 9, serving as the first drip plate 91 and the second drip plate 92 respectively, are provided. The upper surface of the first drip plate 91 is fixed to the first C-shaped part 61 (specifically, by welding, and the first drip plate 91 and the first C-shaped part 61 are made of the same material), and the upper surface of the second drip plate 92 is fixed to the second C-shaped part 62 (specifically, by welding, and the second drip plate 92 and the second C-shaped part 62 are made of the same material). There is a gap 93 between the first drip plate 91 and the second drip plate 92.
[0065] The water collection tank 10 is fixed on the top cover and located below the two drip plates 9, so that the water on the two drip plates 9 can drip into the water collection tank 10;
[0066] The upper end of the drain pipe 11 is fixed to the lower surface of the water collection tank 10, and the internal channel of the drain pipe 11 is connected to the inside of the water collection tank 10. The other end of the drain pipe 11 extends out of the prefabricated cabin. The purpose is that the above structure forms a third waterproof structure. Through this structure, when too much rainwater accumulates and cannot flow away through the second layer of protection, the accumulated rainwater will drip along the two drip plates 9 (i.e., the first drip plate 91 and the second drip plate 92) to the water collection tank 10, and then flow through the drain pipe 11 to the outside of the prefabricated cabin top cover, ensuring that rainwater will not leak into the prefabricated cabin.
[0067] The water collection tank 10 and some of the drainage pipes 11 are located inside the prefabricated cabin; the purpose is to increase aesthetics and concealment.
[0068] like Figure 4 As shown, a first C-shaped edging piece 12 is installed on the vertical side wall perpendicular to the plane 1 at the top of the top cover, and the first C-shaped edging piece 12 extends in the vertical direction, and the first C-shaped edging piece 12 fixes and wraps around the vertical side of the first C-shaped piece 61 (specifically, it is welded, and the first C-shaped edging piece 12 and the first C-shaped piece 61 are made of the same material); the purpose is to ensure that there is no water leakage here.
[0069] like Figure 5As shown, a second C-shaped edging piece 13 is installed on the vertical side wall perpendicular to the plane 2 at the bottom of the top cover, and the second C-shaped edging piece 13 extends in the vertical direction, and the second C-shaped edging piece 13 fixes and wraps around the vertical side of the second C-shaped piece 62 (specifically, it is welded, and the second C-shaped edging piece 13 and the second C-shaped piece 62 are made of the same material); the purpose is to ensure that there is no water leakage here.
[0070] The above embodiments are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Various modifications or variations that can be made by those skilled in the art without creative effort within the scope of the appended claims are still within the scope of protection of this patent.
