Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a waterproof construction method for a large opening of a color corrugated steel plate roof. Background Art

[0002] Metallurgical industrial plants are mostly made of steel structures, and their roofs are often made of colored corrugated steel sheets. This roof structure fixes the colored steel sheets with purlins and purlin supports to form a structure with alternating crests and troughs, which has good waterproof performance. However, in metallurgical projects, due to process requirements, ventilators and process pipelines passing through the roof are often required, which requires holes to be opened on the colored corrugated steel sheet roof, leading to potential leakage problems.

[0003] Colored corrugated steel sheets cannot be welded due to their material, and the slope of the roof makes hole sealing a construction difficulty. Using steel plates to replace colored corrugated steel sheets is not only costly, but also difficult to connect and prone to water leakage. Waterproof material sealing is easy to fall off, making it difficult to stop water flow and having poor waterproofing effect. In addition, during the construction process, it was also found that, especially when welding the side waterproofing sheets, the existing welding equipment is relatively simple, relies on manual operation, is inefficient, and manual operation is difficult to achieve the desired effect. In addition, the steel plates used for construction need to be measured on site and then produced by the manufacturer, which takes a long time. Summary of the invention

[0041] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Embodiment 1:

[0043] See also Figure 1-Figure 3 The present application provides a method for waterproofing a large opening of a colored corrugated steel sheet roof, comprising the following steps:

[0044] S1. Use steel plates to seal the holes in the middle of large steel components 1. The thickness of the steel plates should be 4mm, and both sides should be treated with rust removal and anti-corrosion.

[0045] Among them, by cutting 4mm thick steel plates and welding them to fill the interior of the large steel component 1, the interior is completely sealed, avoiding the problem of difficulty in sealing due to a large gap between the legs and the colored corrugated steel plates, thereby effectively preventing rainwater from penetrating. Compared with the traditional method of filling with structural adhesive, this method is more reliable, because when the gap is large, the structural adhesive is often difficult to fully fill, and in the environment of a metallurgical plant with large vibrations, the structural adhesive is prone to cracking or falling off, resulting in poor waterproofing effect.

[0046] S2. Use welding equipment to weld the side waterproofing plates 4 on the left and right sides of the large steel structure 1. The side waterproofing plates 4 extend outward by two peaks, and the ends of the side waterproofing plates 4 are preferably bent into an angle of 135°.

[0047] Among them, since the colored corrugated steel sheet is too thin to be welded, and there is a gap between the large steel component 1 and the colored corrugated steel sheet roof 2, which will cause leakage. The side waterproof board 4 is made of 4mm thick steel plate, welded to both sides of the large steel component 1, and extended outward by at least two peaks, which can guide the rainwater to the trough of the colored corrugated steel sheet roof 2 around the large steel component 1, avoiding the trough of the colored corrugated steel sheet roof 2 to overflow, and drain the rainwater to a distance outside the hole. The overflowing rainwater will flow into one or two troughs around it, and will not cause leakage. The end of the side waterproof board 4 should be bent at an angle of 135° to facilitate the flow of rainwater.

[0048] S3. Use steel plates to set upper waterproof panels 5 and lower waterproof panels 3 at the upper and lower ends of the large steel structure 1. The two ends of the upper waterproof panels 5 and lower waterproof panels 3 are aligned with the two ends of the side waterproof panels 4, and are welded to the side waterproof panels 4 in S2. The width of the upper waterproof panel 5 should be 100mm, and a water stop strip 5-1 with a height of 50mm is set at the end of the upper waterproof panel 5. The width of the lower waterproof panel 3 should be 300mm.

[0049] Among them, the upper waterproof board 5 and the lower waterproof board 3 are respectively arranged on the upper and lower parts of the large steel structure 1, and are connected by welding. A water stop strip 5-1 is set at the end of the upper waterproof board 5, and the two ends of the upper waterproof board 5 and the lower waterproof board 3 are aligned with the two ends of the side waterproof board 4, and the upper waterproof board 5 and the lower waterproof board 3 should be set with the same slope as the color corrugated steel sheet roof 2, and arranged close to the color corrugated steel sheet roof 2. It should be noted that the main function of the upper waterproof board 5 is to facilitate the overlap with the horizontally laid color corrugated steel sheet 6, and its width can be set shorter, preferably 100mm. The main function of the lower waterproof board 3 is to prevent rainwater from flowing back into the factory building from the bottom when it rains heavily, and its width should be slightly wider, preferably 300mm.

[0050] S4. Colored corrugated steel sheets 6 are laid horizontally from the upper part of the large steel structure 1 to the ridge. The peak height of the horizontally laid colored corrugated steel sheets 6 should be 50-80 mm.

[0051] Among them, the horizontally laid colored corrugated steel plate 6 is arranged between the roof ridge and the large steel structure 1 and is fully spread. The horizontally laid colored corrugated steel plate 6 and the water stop strip 5-1 are fixed with waterproof self-tapping nails 8. In order to strengthen the strength of the horizontally laid colored corrugated steel plate 6, the horizontally laid colored corrugated steel plate 6 and the colored corrugated steel plate roof 2 can also be reinforced with waterproof self-tapping nails 8. It should be noted that the horizontally laid colored corrugated steel plate 6 is equivalent to laying another roof on the existing colored corrugated steel plate roof 2 to form a double-layer roof. The function of this roof is to divert rainwater from upstream to both sides, and no longer flow through the opened openings, thereby fundamentally solving the leakage problem.

[0052] S5. Use flat color plate 7 to overlap and treat between the ridge and the horizontal colored corrugated steel plate 6 for waterproofing. The flat color plate 7 is fixed to the ridge and the horizontal colored corrugated steel plate 6 with waterproof self-tapping screws 8, and the horizontal colored corrugated steel plate 6 is overlapped to the inner side of the water stop strip 5-1 on the upper waterproof plate 5 and fixed with waterproof self-tapping screws 8.

[0053] Among them, the horizontally laid colored corrugated steel sheet 6 is connected to the wall tiles in the ridge direction with a flat colored plate 7 and fixed by waterproof self-tapping screws 8. According to the structural characteristics of the colored corrugated steel sheet roof 2 of metallurgical engineering, for example, when the wall tiles in the ridge direction are higher than the horizontally laid colored corrugated steel sheet 6, the flat colored plate 7 is arranged on the inner side of the ridge; if it is lower than the height of the horizontally laid colored corrugated steel sheet 6, the flat colored plate 7 is arranged on the outer side of the ridge. It should be noted that in order to reduce the probability of water leakage in the roof, the colored corrugated steel sheet fixed with waterproof self-tapping screws 8 can also have waterproof glue applied to the heads of the waterproof self-tapping screws 8.

[0054] In summary, the above-mentioned method of waterproofing large openings on the colored corrugated steel sheet roof 2 is safer, especially the waterproofing construction method of adding horizontally laid colored corrugated steel sheets 6 and reasonably overlapping them, which diverts rainwater from the upper part of the large opening, effectively solving the problem of water leakage caused by the inability to weld the colored corrugated steel sheets and steel components. The waterproofing effect is relatively good, and the horizontally laid colored corrugated steel sheets 6 used are light in weight, low in cost, and convenient to construct.
