[0025] like Figure 1 As shown, the utility model provides a cast-in-situ concrete slope protection plate template, including a first support plate 1, a second support plate 2 and a baffle 3, a cover plate 4 is provided between the first support plate 1 and the second support plate 2, and both ends of the baffle 3 are detachably connected to the lower ends of the first support plate 1 and the second support plate 2, so as to be assembled into a U-shaped structure on the slope surface. During construction, concrete is poured inside the U-shaped structure, so the side walls of the first support plate 1, the second support plate 2 and the baffle 3 that are used to contact the concrete are called inner side walls;

[0026] Here, the lower ends of the first support plate 1 and the second support plate 2 refer to the ends of the first support plate 1 and the second support plate 2 connected to the baffle 3 when the first support plate 1, the second support plate 2 and the baffle 3 are assembled into a U-shaped structure on the slope;

[0027] Here, screws can be provided at the lower ends of the first support plate 1 and the second support plate 2, and both ends of the baffle plate 3 can be provided in the through holes corresponding to the screws. The two ends of the baffle plate 3 are respectively passed through the screws at the lower ends of the first support plate 1 and the second support plate 2, and then locked with nuts, so that the baffle plate 3 can be detachably connected to the lower ends of the first support plate 1 and the second support plate 2;

[0028] The connection method between the cover plate 4 and the first support plate 1 and the second support plate 2 can be the connection method in the prior art, or the connection method described in the following embodiments. The cover plate 4 is mainly used to smooth or pattern the concrete poured in the U-shaped structure.

[0029] The lower edges of the outer walls of the first support plate 1, the second support plate 2 and the baffle plate 3 are all bonded with rubber sheets 5, which extend outside the bottom surface of the component to adhere to the slope. The outer walls of the first support plate 1, the second support plate 2 and the baffle plate 3 are also provided with a clamping assembly, which includes:

[0030] an ear plate 6 connected to the outer side wall of the first support plate 1 and / or the second support plate 2 and / or the baffle plate 3, wherein the ear plate 6 is parallel to the bottom surface of the first support plate 1 and / or the second support plate 2 and / or the baffle plate 3, and a threaded hole is formed on the ear plate 6, through which a bolt 7 is passed;

[0031] The pressure plate 8 is strip-shaped and is arranged below the ear plate 6 along the length direction of the first support plate 1 and / or the second support plate 2 and / or the baffle 3. The lower end of the bolt 7 is rotatably connected to the pressure plate 8 to drive the pressure plate 8 to press the rubber sheet 5.

[0032] Here, a first bearing 9 is provided on the top surface of the pressure plate 8 , and the lower end of the bolt 7 is fixed to the center of the first bearing 9 to be rotatably connected to the pressure plate 8 .

[0033] Here, the outer side walls of the first support plate 1, the second support plate 2 and the baffle 3 refer to the side walls on the first support plate 1, the second support plate 2 and the baffle 3 that are opposite to their respective inner side walls, and the bottom surfaces of the first support plate 1, the second support plate 2 and the baffle 3 refer to the surfaces that are in contact with the slope when the first support plate 1, the second support plate 2 and the baffle 3 are assembled into a U-shaped structure on the slope.

[0034] The above embodiment is used as follows: The first support plate 1, the second support plate 2, and the baffle plate 3 are assembled into a U-shaped structure on a slope. The rubber sheet 5 is then flipped outwardly from the U-shaped structure to fit the slope. The bolts 7 are then rotated to bring the lower end closer to the slope. Driven by the bolts 7, the pressure plate 8 gradually compresses the rubber sheet 5, causing the rubber sheet 5 to fit more tightly against the slope. Concrete is then poured inside the U-shaped structure, and the cover plate 4 is then translated from the lower end to the upper end of the U-shaped structure to smooth or pattern the concrete surface.

[0035] It is not difficult to see from the use process of the above embodiment that the rubber sheet 5 can avoid concrete slurry from seeping along the bottom of the U-shaped structure as much as possible after it is tightly attached to the slope surface.

[0036] In another embodiment, the cast-in-place concrete slope protection board template further includes:

[0037] The fixing rod 10 is connected to the bottom surface of the first supporting plate 1 and / or the second supporting plate 2 and / or the baffle 3 to be inserted into the slope to fix the first supporting plate 1 and / or the second supporting plate 2 and / or the baffle 3.

[0038] Specifically, barbs may be provided on the surface of the fixing rod 10 so that the fixing rod 10 is more firmly connected to the soil after being inserted into the soil.

[0039] In the above embodiment, a fixing rod 10 is provided on the bottom surface of the first support plate 1 and / or the second support plate 2 and / or the baffle plate 3. After the fixing rod 10 is inserted into the slope soil, the connection between the first support plate 1 and / or the second support plate 2 and / or the baffle plate 3 and the slope soil can be made more secure, and a better reaction force can be provided for the bolt 7, so that the pressure plate 8 can press the rubber sheet 5 more forcefully.

[0040] In the prior art, the cover plate 4 is driven by a motor through a pull rope, but it is not convenient to set up a power supply on the slope protection construction site. The present application also provides a structure that can manually drive the cover plate 4 to move horizontally.

[0041] In another embodiment, the interior of the first support plate 1 is hollow, and a screw rod 11 is rotatably connected to the first support plate 1 along the length direction. Here, a second bearing 12 can be provided on the inner wall of the lower end of the first support plate 1, and the lower end of the screw rod 11 can be fixed to the center of the second bearing 12. The upper end of the screw rod 11 passes through the upper end of the first support plate 1 and is connected to a handwheel 16. Here, a circular hole for passing the screw rod 11 is opened at the upper end of the first support plate 1, and a third bearing 13 is provided in the circular hole. The screw rod 11 passes through the center of the third bearing 13 and the third bearing 13 is fixedly connected. A nut 14 is threadedly connected to the part of the screw rod 11 inside the first support plate 1, and a first support rod 15 is connected to the nut 14. A first strip hole is opened on the top surface of the first support plate 1 along the length direction, and the first support rod 15 passes through the first strip hole and extends to the outside of the first support plate 1;

[0042] The second support plate 2 is hollow inside, and a polished rod is connected to the inside of the second support plate 2 along the length direction. A slider is slidably sleeved on the polished rod, and the slider is connected to the second support rod. A second strip-shaped hole is opened on the top surface of the second support plate 2 along the length direction, and the second support rod extends through the second strip-shaped hole to the outside of the second support plate 2;

[0043] The cover plate 4 is provided with a first plugging hole corresponding to the first support rod 15 and a second plugging hole corresponding to the second support rod at both ends.

[0044] When using the above embodiment, construction workers only need to rotate the handwheel 16 to drive the screw 11 to rotate. Due to the limitation of the first support rod 15, the nut 14 and the first support rod 15 can move along the first strip hole, thereby driving the cover plate 4 to move above the first support plate 1. The cover plate 4 then drives the second support rod and the slider to move. Due to the limitation of the second support rod, the cover plate 4 can be placed horizontally between the first support plate 1 and the second support plate 2, so that the lower surface of the cover plate 4 can smooth or pattern the concrete poured in the U-shaped structure. At the same time, because the cover plate 4 is plug-connected to the first support rod 15 and the second support rod, the cover plate 4 can be easily removed from the first support rod 15 and the second support rod for replacement and maintenance.

[0045] In another embodiment, the lower surface of the cover plate 4 is provided with an ironing plate 17 or a patterned plate whose width is adapted to the distance between the first support plate 1 and the second support plate 2 .

[0046] During construction, if a thinner concrete thickness or a patterned concrete surface is required, the screed plate 17 in the above embodiment protrudes between the first and second support plates 1, 2, thereby scraping off excess concrete on the surface to achieve the desired thinning. The lower surface of the patterned plate can be patterned according to construction requirements.

[0047] In another embodiment, the top surfaces of the first support plate 1 and the second support plate 2 are coated with a wear-resistant and drag-reducing coating. Since the cover plate 4 and the first support rod 15 and the second support rod are all plugged into each other, part of the surface of the cover plate 4 is still in contact with the top surfaces of the first support plate 1 and the second support rod 2. The fixed cover plate 4 will rub against the first support plate 1 and the second support plate 2 during movement. The provision of the wear-resistant and drag-reducing coating here can reduce friction, facilitate the movement of the cover plate 4, and reduce wear of the cover plate 4, the first support rod 15, and the second support rod.

[0048] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
