[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.
[0024] The following is a reference to the appendix. Figure 1 To be continued Figure 4 This invention describes an adjustable drainage slope adjustment device for use on antique-style metal tile roofs.
[0025] Traditional village houses have various roof slopes, while metal tile installation requires meeting a specific drainage slope range (usually ≥15°). Current technology, if the original roof slope is insufficient, truss and rectangular tube structures need to be adjusted as a whole, resulting in complex construction, material waste, and high costs.
[0026] Therefore, this adjustment device is installed on the rectangular tube 11, which is installed on the truss 1. The rectangular tube 11 is provided with a tile strip 3, which can slide along the first direction A. The adjustment device includes multiple sets of adjustment components 2, which are located between the rectangular tube 11 and the tile strip 3. Multiple sets of adjustment components 2 are arranged at intervals along the horizontal direction of the roof. The height of the tile strip 3 is adjusted by rotating the multiple sets of adjustment components 2. According to the drainage slope, the adjustment components 2 are adjusted sequentially from the eaves to the ridge, and each set of adjustment components 2 is adjusted according to a linear gradient to adjust to the required drainage slope.
[0027] By adjusting the height of each of the two adjustment components, an overall slope gradient is formed to ensure smooth drainage. The height of the batten strip can be precisely raised and lowered within ±50mm, thereby changing the local slope (adjustment range ±5°).
[0028] This adjustment component 2 is a non-removable structure: it can be directly adapted to the existing rectangular tube 11 without adjusting the light steel roof truss, saving more than 90% of the labor time. The original roof truss and battens 3 can be completely retained, reducing material waste. At the same time, it supports local fine-tuning, solving the problem of unifying complex slopes.
[0029] This adjustment device is typically used in traditional village houses. Application scenario: A village house originally had a slope of 10°, which needs to be adjusted to 18° to install metal tiles.
[0030] S1. First, install a set of adjustment components 2 every 0.5m on the roof rectangular tube 11.
[0031] S2. According to the slope calculation model, adjust the adjustment component 2 at the eaves to the lowest point (-50mm), adjust the adjustment component 2 at the middle point sequentially according to the linear gradient, and adjust the adjustment component 2 at the ridge to the highest point (+50mm). In other embodiments of this utility model, according to the slope calculation model, adjust the adjustment component 2 at the eaves to the lowest point (-50mm), adjust the adjustment component 2 at the ridge to the highest point (+50mm), and adjust the adjustment component 2 at the middle point sequentially according to the linear gradient.
[0032] S3. Fix each set of adjustment components 2, install the tile strips 3 and metal tiles to form a uniform drainage slope. In other embodiments of this utility model, the tile strips 3 can be located above the adjustment components 2 when adjusting the adjustment components 2, and the metal tiles can be installed after the adjustment is completed.
[0033] The adjusting component 2 includes multiple cams 21, which are fixedly connected by a rotating shaft 22. The multiple cams 21 rotate relative to the bearing strip 3 with the rotating shaft 22 as the center. The multiple cams 21 abut against the bearing strip 3 to change the height of the bearing strip 3. By setting multiple cams 21, sufficient support is provided for the bearing strip 3. Specifically, the multiple cams 21 have the same angle on the rotating shaft 22, so that when the cams 21 are rotated, all the cams 21 on the adjusting component 2 can abut against the bearing strip 3.
[0034] Adjustment component 2 also includes support plate 23, which is fixedly connected to rectangular tube 11. The support frame allows the rotating shaft 22 to rotate. Preferably, the support frame has a rotating groove, which is rotatably connected to the rotating shaft 22.
[0035] A crank handle 24 is detachably connected to the rotating shaft 22. The crank handle 24 powers the cam 21 to rotate. The rotating shaft 22 and the crank handle 24 are detachably connected. After adjustment, the crank handle 24 can be separated from the rotating shaft 22. Preferably, a spline is connected to the rotating shaft 22, and a keyway is provided on the crank handle 24. The spline and the keyway can be inserted into each other. After the spline and the keyway are inserted into each other, the rotating shaft 22 rotates synchronously by rotating the crank handle 24.
[0036] Preferably, the support plate 23 is provided with a dial, and when the crank handle 24 is rotated, the rotation angle of the cam 21 can be determined by the position of the crank handle 24 and the dial.
[0037] A limiting component 4 is provided on the rotating shaft 22. After the height of the roof tile strip 3 is adjusted, the limiting component 4 restricts the rotating shaft 22 from rotating. Specifically, the limiting component 4 includes a limiting wheel 41, which is fixedly connected to the rotating shaft 22. The limiting wheel 41 has a limiting groove, and the support plate 23 has a sliding groove. The support plate 23 is slidably connected to a limiting block 42 through the sliding groove. The limiting block 42 can engage with the limiting groove. After the height of the roof tile strip 3 is adjusted, the limiting block 42 is pushed until it engages with the limiting groove.
[0038] Preferably, a spring is fixedly connected inside the slide groove, and the end of the spring away from the slide groove is fixedly connected to the limiting block 42. Through the spring, the limiting block 42 is always engaged with the limiting groove.
[0039] When adjusting the adjusting component 2, when the tile strip 3 is above the adjusting component 2, the tile strip 3 is provided with a positioning component. The positioning component restricts the tile strip 3 from sliding along the first direction A. Specifically, the positioning component includes a positioning tube 31, which is fixedly connected to the tile strip 3. An opening groove is provided on the rectangular tube 11, and the positioning tube 31 is slidably connected to the opening groove.
[0040] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. 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 possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
