Description

Technical Field

[0001] The invention relates to the technical field of color steel plate roofs, in particular to a leakproof color steel plate roof connection structure and an installation method thereof. Background Art

[0002] The base plates of color steel sheets are cold-rolled base plates, hot-dip galvanized base plates and electro-galvanized base plates. The coating types can be divided into polyester, silicon-modified polyester, polyvinylidene fluoride and plastisol. The surface state of color steel sheets can be divided into coated sheets, embossed sheets and printed sheets. Color steel sheets are widely used in industries such as construction, home appliances and transportation. For the construction industry, they are mainly used for roofs, walls and doors of industrial and commercial buildings such as steel structure factories, airports, warehouses and refrigeration.

[0003] At present, when the color steel plate roof is used, a cover plate is usually laid at the ridge to fold the interface of the two roofs to prevent leakage. However, due to the existence of the ridges on the color steel plate, the bottom of the cover plate cannot effectively fit with the color steel plate. Therefore, in a storm, the rainwater near the ridge on the color steel plate is easy to flow upward under the action of strong wind, resulting in leakage at the ridge. Secondly, when the adjacent color steel plates on the color steel plate roof are spliced, the ridges at the ends of the two color steel plates overlap each other, and the self-tapping screws are used to fix the roof frame at the overlapping ridges. Although this method can guide the rainwater, when the gap between the two overlapping color steel plates is small, the rainwater is easy to penetrate into the joint of the two color steel plates under the capillary action, thereby causing the roof to leak. To this end, a leakproof color steel plate roof connection structure and an installation method thereof are proposed. Summary of the invention
