Description

Technical Field

[0001] This invention relates to a connection structure for horizontal roof tiles and a method for installing the horizontal roof tiles, belonging to the technical field of roof horizontal roof 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] Metal horizontal roof tiles are typically connected side-by-side using connectors to create a waterproof structure. These connectors often have gaps, posing a risk of leakage on small pitched roofs. Furthermore, because metal horizontal tiles are relatively thin, the connection points are easily deformed by foot pressure, potentially damaging the original connection structure and causing leaks. Therefore, horizontal waterproofing, especially with metal horizontal tiles, remains a challenge: simpler structures are prone to leaks, while complex structures are more difficult to manufacture, costly to produce, and challenging 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 the present invention is to provide a horizontal tile connection structure that can effectively improve the waterproof effect and increase the strength of the connection, as well as a method for installing the horizontal tile.

[0006] The present invention provides a technical solution to solve the above-mentioned technical problems as follows: a transverse tile connection structure, comprising transverse tiles and connectors, wherein the widths of the transverse tiles and connectors are matched; a water-stop groove is formed on the upper surface of one transverse end of the transverse tile, which is arranged along the width direction of the transverse tile; at least two water-guiding strips are provided between the water-stop groove and the transverse end of the transverse tile, which are arranged along the width direction of the transverse tile, and a water-stop adhesive strip is provided between adjacent water-guiding strips; the connector includes a base plate, the left and right ends of the base plate are respectively provided with an upwardly bent and inwardly extended insertion flange and an upwardly bent and inwardly extended waterproof flange; the upper surface of the base plate is provided with multiple concave ribs arranged parallel to the water-guiding strips; the transverse tile connection structure is further provided with a water-stop groove formed on the upper surface of the transverse tile, which ... The tile comprises two adjacent tiles with their ends overlapping, namely a first tile and a second tile. The first tile, the second tile, and the connector are arranged in parallel. The first tile is located above the connector, and the end of the first tile is inserted into the insertion flange of the connector. The second tile is located above the first tile, and the end of the second tile is located at the water-stop groove of the first tile. The lower surface of the second tile is in contact with the water-stop strip of the first tile. The end of the transverse tile away from the water-stop groove is provided with a downward folded flange. When the two adjacent transverse tiles overlap, the downward folded flange of the upper transverse tile is located in the water-stop groove of the lower transverse tile.

[0007] Preferably, the water guide strips of the transverse tile are grooves, the number of water guide strips is greater than or equal to 4, and the water guide strips are evenly spaced; the number of concave ribs of the connector is 2 to 6, the concave ribs are evenly spaced, and the concave ribs of the connector are located between adjacent water guide strips of the first tile.

[0008] Preferably, the transverse tile and the connecting piece are both integral steel plate bending and stamping parts.

[0009] Preferably, the length of the waterproof flange extending inward is less than the length of the plug flange extending inward; the concave rib is a groove stamped on the upper surface of the substrate, and the cross-section of the concave rib is an inverted trapezoid, an arc, or an inverted triangle.

[0010] 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. 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.

[0011] Preferably, the front end of the substrate is provided with a downwardly bent edge, and the downwardly bent edge of the connector is in contact with the water guiding part of the first tile.

[0012] Preferably, the insertion flange, waterproof flange, and concave rib are respectively provided with gaps between them and the upper end of the substrate; the position of the gap corresponds to the position of the fixing part of the first tile.

[0013] Another technical solution provided by the present invention to solve the above-mentioned technical problems is as follows: a method for installing horizontal tiles, using the above-mentioned horizontal tile connection structure, when laying horizontal tiles, first lay horizontal tiles in the same row in the left-right direction, fix the fixing part of the first tile to the keel frame of the roof with fasteners, then set a connector below the end of the first tile, insert the end of the first tile into the insertion flange of the connector, and then insert the end of the second tile above the end of the first tile, so that the second tile overlaps the first tile, the end of the second tile is located at the water-stop groove of the first tile, the lower notch of the first tile matches the water-guiding part of the second tile, the upper notch, waterproof dam and fixing part of the first tile matches the upper notch of the second tile, and finally fix the fixing part of the second tile to the keel frame of the roof with fasteners.

[0014] Preferably, when laying the horizontal tiles, first lay the bottom row of horizontal tiles in the left and right direction, then lay the top row of horizontal tiles in the left and right direction, and attach the downward-turning slot of the upper horizontal tile to the upward-turning slot of the lower horizontal tile. The downward-turning edge 116 of the upper horizontal tile 1 is located in the water-stop groove 111 of the lower horizontal tile (1).

[0015] The beneficial effects of this invention are: (1) The horizontal tile connection structure of the present invention has two horizontal tiles overlapping each other. A water-stop groove, a water guide strip, and a downturned edge are provided on the lower horizontal tile. The downturned edge is located in the water-stop groove to form the first layer of waterproofing. Several water guide strips can guide rainwater downwards to the water guide part and discharge it from the drain. The elastic water-stop strip fills the gap between the two horizontal tiles to prevent water from flowing horizontally to the right. A plug-in connector is set below the lower horizontal tile. The waterproof upturned edge and concave rib of the connector form a multi-layer water guide structure, which further improves the waterproofing effect at the connection of the horizontal tiles and solves the risk of water leakage when using small-slope roofs (less than 20%). It can pass the simulated rain test test at a slope of 13%. In addition, the upturned edge and concave rib of the connector both act as reinforcing ribs, which effectively improves the strength of the entire connector and enhances the strength of the connection between the left and right horizontal tiles. It solves the problem of deformation at the connection after being stepped on. It does not deform when stepped on by a person weighing 60kg.

[0016] (2) The transverse tile connection structure of the present invention forms an upper and lower transverse 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.

[0017] (3) The installation method of the horizontal tile of the present invention is that the horizontal tile and the connector are plugged together, which makes the installation extremely convenient and can greatly improve the construction efficiency. Attached Figure Description

Detailed Implementation

[0021] Example 1, see Figures 1 to 4 The transverse tile connection structure of this embodiment includes a transverse tile 1 and a connector 2. Both the transverse tile 1 and the connector 2 are integral steel plate bending and stamping parts. The widths of the transverse tile 1 and the connector 2 are matched. A water-stop groove 111 is formed on the upper surface of the right end of the transverse tile 1, which is arranged along the width direction of the transverse tile 1. Four water-guide strips 112 are arranged along the width direction of the transverse tile 11 between the water-stop groove 111 and the right end of the transverse tile 1. The water-guide strips 112 of the transverse tile 1 are grooves, and the water-guide strips 112 are evenly spaced. A water-stop rubber strip 3 is provided between the first and second water-guide strips 112 on the left side.

[0022] The connector 2 includes a base plate 21. The right end of the base plate 21 has an upwardly bent and then parallel-extending insertion flange 22. The left end of the base plate 21 has an upwardly bent and then parallel-extending waterproof flange 23. The rightward extension length of the waterproof flange 23 is less than the leftward extension length of the insertion flange 22. Three recessed ribs 24, parallel to the water guide strip 112, are formed on the upper surface of the base plate 21. The recessed ribs 24 are grooves stamped into the upper surface of the base plate 21, and their cross-section is arc-shaped. The recessed ribs 24 are evenly spaced.

[0023] The horizontal tile 1 comprises two adjacent tiles with their ends overlapping. The left tile is the first tile 11, and the right tile is the second tile 12. The first tile 11, the second tile 12, and the connector 2 are arranged in parallel. The first tile 11 is located above the connector 2, and its right end is inserted into the insertion flange 22 of the connector 2. The second tile 12 is located above the first tile 11, and its left end is located at the water-stop groove 111 of the first tile 11. The lower surface of the second tile 12 is in contact with the water-stop strip 3 of the first tile 11. The concave rib 24 of the connector 2 is located between adjacent water-guiding strips 112 of the first tile 11. The front end of the base plate 21 is provided with a downwardly bent lower flange 25, which is in contact with the water-guiding portion 121 of the first tile 11. The insertion flange 22, the waterproof flange 23, and the concave rib 24 are respectively provided with gaps between themselves and the upper end of the base plate 21. The position of the gap corresponds to the position of the fixing part 133 of the first tile 11.

[0024] The end of the transverse tile 1 away from the water-stop groove 111 is provided with a downward folded edge 116. When two adjacent transverse tiles 1 are joined together, the downward folded edge 116 of the upper transverse tile 1 is located in the water-stop groove 111 of the lower transverse tile 1.

[0025] See Figure 5 and Figure 6 The upper end of the transverse tile 1 has an upward-bending and inwardly extending upturned groove 131. Above the upturned groove 131 is an upward-bending and outwardly extending waterproof dam 132, with two upwardly protruding peaks. Above the waterproof dam 132 is a downward-bending and outwardly extending fixing part 133, and above the fixing part 133 is an upward-bending and inwardly extending water-blocking part 134. The lower end of the transverse tile 1 has a downward-bending and inwardly extending water-guiding part 121, with a downward-bending downturned groove 122 above it. The bottom of the water-guiding part 121 has a drain outlet 123. The upper end of the transverse tile 1, away from the water-stop groove 111, has an upper notch fitting part 135 that matches the other end of the transverse tile 1. The lower end of the transverse tile 1, near the water-stop groove 111, has a lower notch fitting part 124 that matches the other end of the transverse tile 1.

[0026] Two adjacent horizontal tiles 1 are snapped together during installation. The fixing part 133 is fixed to the roof joist frame by fasteners 5. The downward-folding groove 122 of the upper horizontal tile 1 engages with the upward-folding 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 upward-folding groove 131 of the lower horizontal tile 1. Furthermore, a certain gap is left between the connection between the upward-folding groove 131 and the waterproof dam 132 and the water-guiding part 121, which can effectively prevent capillary action.

[0027] In this embodiment, the installation method of the horizontal tiles involves laying the horizontal tiles 1. First, lay the horizontal tiles 1 in the same row in the left-right direction. Then, fix the fixing part 133 of the first tile 11 to the roof joist frame using fasteners 5. Next, install a connector 2 below the right end of the first tile 11 and insert the right end of the first tile 11 into the insertion flange 22 of the connector 2. Finally, insert the left end of the second tile 12 above the right end of the first tile 11, so that the second tile 12... The left end overlaps the right end of the first tile 11, and the left end of the second tile 12 is located at the water-stop groove 111 of the first tile 11. The lower notch fitting part 124 of the first tile 11 mates with the water-guiding part 121 of the second tile 12. The upward-turning groove 131, the waterproof dam 132, and the fixing part 133 of the first tile 11 mate with the upper notch fitting part 135 of the second tile 12. Finally, the fixing part 133 of the second tile 12 is fixed to the roof joist frame with fasteners 5. First, lay the lower row of horizontal tiles 1 in the left-right direction, then lay the upper row of horizontal tiles 1 in the left-right direction, and engage the downward-turning groove 122 of the upper horizontal tile 1 with the upward-turning groove 131 of the lower horizontal tile 1.

[0028] 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.

[0029] The insertion flange 22 of the first tile 11 is locked to the right end of the first tile 11, which prevents water from flowing laterally. A small amount of water flowing onto the substrate 21 can be guided into the water guiding part 121 by the concave rib 24. The waterproof flange 23 is responsible for the last layer of waterproofing, ensuring that the waterproofing is foolproof.

[0030] Example 2: The horizontal tile connection structure of this example is the same as that of Example 1, except that the overlapping method of the first tile 11 and the second tile 12 can be interchanged. That is, the first tile 11 overlaps the second tile 12, the connector 2 is located below the second tile 12, and the insertion flange 22 of the connector 2 is set at the left end of the connector 2. The left end of the second tile 12 is inserted and fixed in the insertion flange 22 of the connector 2.

[0031] Example 3: The transverse tile connection structure of this example is the same as that of Example 1, except that a raised peak is provided at the waterproof dam 132.

[0032] Example 4: The transverse tile connection structure of this example is the same as that of Example 1, except that the cross-section of the concave rib 4 is an inverted trapezoid.

[0033] Example 5: The transverse tile connection structure of this example is the same as that of Example 1, except that the cross-section of the concave rib 4 is an inverted triangle. There are 4 concave ribs 4 and 5 water guide strips 112.

[0034] Obviously, the above embodiments are merely examples to clearly illustrate the embodiments of the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
