Description

Technical Field

[0001] This utility model relates to a horizontal tile and its installation structure, belonging to the technical field of roof horizontal tiles. Background Technology

[0002] Roofing tiles are an important waterproofing material. Currently, there are various types of roofing tiles available, including cement tiles, horizontal tiles, and photovoltaic tiles. Among them, metal horizontal tiles are a type of roofing tile with a metal base and a colored coating on the surface. Their horizontal length is much greater than their vertical width. Due to their lightweight, sturdiness, and aesthetic appeal, they have become the mainstream roofing material for prefabricated buildings.

[0003] However, horizontal waterproofing of roof tiles, especially metal roof tiles, has always been a challenge: if the structure of the waterproof roof tile assembly is relatively simple, leaks are likely to occur; while if the structure of the waterproof roof tile assembly is relatively complex, it is difficult to process, has high production costs, and is also difficult to install.

[0004] Chinese patent document CN219298600U discloses a waterproof horizontal tile assembly, comprising two adjacent horizontal tiles. The outer edges of the horizontal tiles are bent downwards and extend inwards to form a first locking hook with a first hook groove, and the outer edges of the horizontal tiles are bent upwards and extend inwards to form a second locking hook with a second hook groove, so that the first locking hook can be hooked and locked into the second hook groove, and the second locking hook can be hooked and locked into the first hook groove. The upper surface of the horizontal tiles also has several water-guiding ribs distributed at intervals, with the front ends of the water-guiding ribs inclined inwards towards the horizontal tiles. This horizontal tile waterproofing structure has room for improvement, especially when applied to low-slope roofs. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a horizontal tile suitable for low-slope roofs that is simple in structure, easy to install, and has good waterproof effect, as well as the installation structure of the horizontal tile.

[0006] The present invention provides a technical solution to solve the above-mentioned technical problems as follows: a horizontal tile suitable for low-slope roofs, characterized in that: a water-stop groove is provided on the upper surface of one horizontal end of the horizontal tile, which is arranged along the width direction of the horizontal tile; at least two water-guide strips are provided between the water-stop groove and the horizontal end of the horizontal tile, which are arranged along the width direction of the horizontal tile; and a water-stop rubber strip is provided between adjacent water-guide strips.

[0007] Preferably, the water guide strip is a groove or a raised rib.

[0008] Preferably, the lower section of the water guide strip has a zigzag line that slopes away from the end of the transverse tile.

[0009] Preferably, a row of water guide lines is provided from top to bottom between the water-stop groove and the water guide strip or between adjacent water guide strips. The water guide lines are obliquely arranged and the lower end of the water guide lines faces away from the end of the transverse tile. The water guide lines are straight or have a bend in the middle.

[0010] Preferably, the number of water guide strips is greater than or equal to four; the water guide strips are arranged at equal intervals.

[0011] Preferably, the transverse tile is made by bending and stamping a metal sheet.

[0012] Preferably, the upper end of the transverse tile is provided with an upwardly bent and inwardly extending upturned groove, and above the upturned groove is a waterproof dam that bends upward and extends outward. The waterproof dam has one or two upwardly protruding peaks, and above the waterproof dam is a fixing part that bends downward and extends outward. Above the fixing part is a water-blocking part that bends upward and extends inward. The lower end of the transverse tile is provided with a water-guiding part that bends downward and extends inward and upward. Above the water-guiding part is a downwardly bent downturned groove, and the bottom of the water-guiding part has a drain outlet. The upper end of the transverse tile away from the water-stop groove has an upper notch fitting part that matches the other end of the transverse tile, and the lower end of the transverse tile near the water-stop groove has a lower notch fitting part that matches the other end of the transverse tile.

[0013] Preferably, the end of the transverse tile with the water-stop groove has an upward-folded upper edge, and the end of the transverse tile away from the water-stop groove has a downward-folded lower edge. When two adjacent transverse tiles are joined together, the upper edge of the lower transverse tile is in contact with the lower surface of the upper transverse tile, and the lower edge of the upper transverse tile is located in the water-stop groove.

[0014] Another technical solution provided by this utility model to solve the above-mentioned technical problem is as follows: the above-mentioned installation structure of horizontal tiles suitable for low-slope roofs has two adjacent horizontal tiles overlapping each other; the upper surface of the lower horizontal tile is in contact with the lower surface of the upper horizontal tile, and the horizontal end of the upper horizontal tile away from the water-stop groove is located at the water-stop groove of the lower horizontal tile.

[0015] Preferably, the upper end of the transverse tile is provided with an upward-bending and inwardly extending upturned groove, and above the upturned groove is a waterproof dam that bends upward and extends outward. The waterproof dam has one or two upwardly protruding peaks, and above the waterproof dam is a fixing part that bends downward and extends outward. Above the fixing part is a water-blocking part that bends upward and extends inward. The lower end of the transverse tile is provided with a water-guiding part that bends downward and extends inward and upward. Above the water-guiding part is a downward-bending and downturned groove, and the bottom of the water-guiding part has a drain outlet. The upper end of the transverse tile away from the water-stop groove has an upper notch fitting part that matches the other end of the transverse tile, and the lower end of the transverse tile near the water-stop groove has a lower notch fitting part that matches the other end of the transverse tile.

[0016] Two adjacent horizontal tiles are snapped together, and the fixing part is fixed to the roof joist frame by fasteners. The downward slot of the upper horizontal tile is engaged in the upward slot of the lower horizontal tile. A water-guiding cavity is formed between the bottom of the water-guiding part of the upper horizontal tile and the upward slot of the lower horizontal tile.

[0017] The beneficial effects of this utility model are:

[0018] (1) The horizontal tiles of this utility model adopt a left-right overlapping form. The lower tiles are provided with a water-stop groove, a water guide strip, and an upward-turned edge in sequence, while the upper tiles are provided with a downward-turned edge located in the water-stop groove. The downward-turned edge, located in the water-stop groove, forms the first layer of waterproofing. Several water guide strips can sequentially guide rainwater downwards into the water guide section and discharge it from the drain outlet. The elastic water-stop strip fills the gap between the left and right tiles to prevent water from flowing horizontally to the right. The upward-turned edge serves as the last layer of waterproofing to ensure that horizontal water flow does not flow under the tiles. After multiple extreme slope tests (15% to 20%), the results were satisfactory. At a 20% slope, rainwater can reach the position of the third water guide strip and flow downwards; at a 15% slope, rainwater can reach the position of the fourth water guide strip and flow downwards.

[0019] (2) The horizontal tiles of this utility model form an upper and lower horizontal tile hook structure, which not only serves to fix the upper and lower tiles, but also forms a natural water seal between the upper and lower tiles to prevent rainwater backflow. In addition, a cavity is set at the upper and lower hook joint to prevent capillary action, further improving the waterproof effect of the roof. The single-peak and double-peak waterproof dams further improve the waterproof effect of the upper and lower hook joints, reducing the occurrence of roof seepage and leakage.

Detailed Implementation

[0032] Example 1, see Figures 1 to 5 This embodiment describes a horizontal tile suitable for low-slope roofs. One end of the horizontal tile 1 has an upwardly folded-up flange 116. The upper surface of one end of the horizontal tile 1 has a water-stop groove 111 extending along the width of the tile 1. At least two water-guiding strips 112 extending along the width of the tile 1 are located between the water-stop groove 111 and the upwardly folded-up flange 116. A water-stop adhesive strip 3 is located between adjacent water-guiding strips 112. The other end of the horizontal tile 1 has a downwardly folded-up flange 117. The water-guiding strips 112 are raised ribs. There are four water-guiding strips 112. The water-guiding strips 112 are evenly spaced.

[0033] The upper end of the horizontal tile 1 is provided with an upward-bending groove 131 that bends upward and extends inward. Above the upward-bending groove 131 is a waterproof dam 132 that bends upward and extends outward. The waterproof dam 132 has an upward-protruding peak. Above the waterproof dam 132 is a fixing part 133 that bends downward and extends outward. Above the fixing part 133 is a water-blocking part 134 that bends upward and extends inward. The lower end of the horizontal tile 1 is provided with a water-guiding part 121 that bends downward and extends inward and upward. Above the water-guiding part 121 is a downward-bending groove 122. The bottom of the water-guiding part 121 has a drain outlet 123. The upper end of the horizontal tile 1 near the downward-bending edge 117 has an upper notch fitting part 135. The lower end of the horizontal tile 1 near the upward-bending edge 116 has a lower notch fitting part 124.

[0034] In this embodiment, during the installation of the horizontal tiles, two adjacent horizontal tiles 1 are overlapped vertically. The upper flange 116 of the lower horizontal tile 1 is in contact with the lower surface of the upper horizontal tile 1. The water-stop strip 3 of the lower horizontal tile 1 is in contact with the lower surface of the upper horizontal tile 1. The lower flange 117 of the upper horizontal tile 1 is located within the water-stop groove 111. The two adjacent horizontal tiles 1 are snapped together, and the fixing part 133 is fixed to the roof joist frame by fasteners 5. The lower flange groove 122 of the upper horizontal tile 1 is engaged with the upper flange groove 131 of the lower horizontal tile 1. A water-guiding cavity 4 is formed between the bottom of the water-guiding part 121 of the upper horizontal tile 1 and the upper flange groove 131 of the lower horizontal tile 1. A certain gap is left between the connection between the upper flange groove 131 and the waterproof dam 132 and the water-guiding part 121, which can effectively prevent capillary action.

[0035] At the joints of the horizontal roof tiles 1, if small gaps exist, rainwater may seep into the roof through capillary action, causing leaks. The drainage cavity 4, by providing a larger space, reduces the impact of capillary action, thus preventing rainwater from seeping through small gaps. Simultaneously, the waterproof dam 132 prevents backflow of rainwater, further improving the waterproofing effect. The cooperation between the cavity 4 and the waterproof dam 132 significantly reduces backflow and seepage of rainwater from the roof. Finally, the rainwater blocked by the cavity 4 and the waterproof dam 132 will be quickly discharged through the drain outlet 123.

[0036] Example 2, see Figure 6 The horizontal tile of this embodiment is applicable to low-slope roofs. The rest is the same as in embodiment 1, except that: there are two upward-protruding peaks at the waterproof dam 132.

[0037] Example 3, see Figure 7The horizontal tile of this embodiment is applicable to low-slope roofs. The rest is the same as in embodiment 1, except that the lower section of the water guide strip 112 is provided with a zigzag line 118 that is inclined away from the end of the horizontal tile 1.

[0038] Example 4, see Figure 8 The horizontal tile of this embodiment is applicable to low-slope roofs. The rest is the same as in embodiment 1. The difference is that a row of water guide lines 114 is provided on one side of the water guide strip 112 from top to bottom. The water guide lines 114 are obliquely arranged and the lower end of the water guide lines 114 faces away from the end of the horizontal tile 1.

[0039] Example 5, see Figure 9 The horizontal tile of this embodiment is applicable to low-slope roofs. The rest is the same as in embodiment 4, except that the water guide strip 112 has a bend in the middle.
