Abstract
Description
Technical Field
[0001] This utility model relates to the field of roof structure technology, and in particular to a waterproof overlapping structure for sloping tile roofs. Background Technology
[0002] In the construction industry, sloping tile roofs are widely used in various civil and industrial buildings due to their good drainage performance and aesthetic appeal. However, the problem of water leakage in sloping tile roofs has always been a major concern in the industry and a key factor affecting the lifespan of the roof and the user experience of the building.
[0003] Traditional sloping tile roofs often use simple overlapping or snap-fit connections at the tile joints. These methods have several drawbacks: overlapping joints provide poor sealing, and during heavy rainfall or prolonged periods of rain, rainwater can easily seep into the roof through the gaps between the tiles, causing leaks and damaging the interior decoration and structure. Utility Model Content

[0010] Preferably, end a of any tile can be connected to end b of any tile; the limiting plate is fitted into the limiting groove.
[0011] Preferably, the limiting groove is formed by the continuous groove walls of the first slot, the arc-shaped groove, and the second slot; the limiting plate is formed by the continuous outer surfaces of the first block, the arc-shaped block, and the second block.
[0012] Preferably, when two adjacent tiles are engaged by the limiting plate and the limiting groove, the arc-shaped block and the arc-shaped groove form a curved surface seal, and the first locking block and the first locking groove, and the second locking block and the second locking groove form a straight plate seal, together forming a three-dimensional anti-leakage channel.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. The curved surface seal is formed by the arc-shaped block and the arc-shaped groove, and the straight plate seal is formed by the first card block and the first card groove, and the second card block and the second card groove, forming a three-dimensional anti-leakage channel, which blocks the rainwater infiltration path in all directions and can effectively deal with leakage problems caused by rainwater, snow accumulation, etc.

[0023] Reference Figure 1-3 The sloping tile roof waterproofing overlapping structure consists of multiple sloping beams 1 and tiles 2, and achieves a reliable waterproofing effect through ingenious design.
[0024] Multiple inclined beams 1 are assembled together to form the roof frame. This frame not only serves as the load-bearing foundation for the entire roof but also provides a stable support surface for the installation of the tiles 2. The material selection for the inclined beams 1 must take into account the load-bearing requirements of the roof and the climatic conditions of the environment. Materials with strong compressive strength and corrosion resistance are usually used to ensure the long-term stability of the frame.
[0025] The roof tile 2 is the core component for preventing leaks, and its structural design directly affects the waterproofing effect of the roof. The roof tile 2 includes an arc-shaped plate 21, a first straight plate 22, and a second straight plate 23. The first straight plate 22 and the second straight plate 23 are respectively fixedly installed on both sides of the arc-shaped plate 21. This structural design allows the roof tile 2 to have a certain curvature, which can guide rainwater to flow smoothly down, while the straight plates on both sides enhance the tightness of the connection with adjacent roof tiles.
[0026] Tile 2 has end a and end b. At end a, a first straight plate 22 has a first slot 221, an arc-shaped plate 21 has an arc-shaped groove 211, and a second straight plate 23 has a second slot 231. The first slot 221, the arc-shaped groove 211, and the second slot 231 are connected sequentially to form a limiting groove. The limiting groove is formed by the continuous groove walls of the first slot 221, the arc-shaped groove 211, and the second slot 231. Its shape and size are precisely designed to provide accurate positioning for connection with the adjacent tile end b.
[0027] At end b of tile 2, a first locking block 222 is provided at the bottom of the first straight plate 22, an arc-shaped block 212 is provided at the bottom of the arc-shaped plate 21, and a second locking block 232 is provided at the bottom of the second straight plate 23. The first locking block 222, the arc-shaped block 212, and the second locking block 232 are connected in sequence to form a limiting plate. The limiting plate is formed by the continuous outer surfaces of the first locking block 222, the arc-shaped block 212, and the second locking block 232. Its shape is adapted to the limiting groove to ensure a tight connection between adjacent tiles.
[0028] End a of any tile 2 can be connected to end b of any other tile 2. When two adjacent tiles 2 are engaged by the locking plate and the locking groove, a multi-layered sealing structure is formed. Specifically, the arc-shaped block 212 and the arc-shaped groove 211 form a curved surface seal. This curved surface contact increases the sealing area, effectively preventing rainwater from seeping in along the arc surface. The first locking block 222 and the first locking groove 221, and the second locking block 232 and the second locking groove 231 form a straight plate seal. The tight fit between the straight plates further enhances the sealing effect, preventing rainwater from leaking through the gaps on both sides. These three seals together constitute a three-dimensional anti-leakage channel, blocking the penetration path of rainwater from all directions and greatly improving the roof's anti-leakage performance.
[0029] Furthermore, this overlapping structure offers the advantage of convenient installation. Due to the precise fit between the limiting plate and the limiting groove, construction workers can quickly and accurately connect adjacent tiles during installation, improving construction efficiency. At the same time, this structural design also facilitates later maintenance and replacement; when a tile is damaged, it can be replaced simply by separating it from the adjacent tiles, without the need for large-scale demolition of the roof structure.
[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
