[0023] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.
[0024] According to Figure 1 、 2 As shown in FIGS. 1, 2, and 3, a construction surface humidity maintaining device is proposed in this embodiment, including:
[0025] Two rollers 2, with a membrane cloth 1 provided between the two rollers 2. Both ends of the membrane cloth 1 are wound around the outer sides of the rollers 2 and fixedly connected to the rollers 2;
[0026] After the concrete tabletop is completed and poured, it will be cured by watering. The membrane cloth 1 is laid on the construction surface to ensure the humidity of the construction surface.
[0027] A positioning frame 4, provided at both ends of the roller 2, with a piercing portion provided at the lower end of the positioning frame 4;
[0028] A clamping member 3, slidably provided on the side of the positioning frame 4, and the clamping member 3 is detachably connected to the roller 2;
[0029] An adjusting assembly, provided at the upper end of the positioning frame 4, for pushing the clamping member 3 to slide on the side of the positioning frame 4 to adjust the height of the clamping member 3.
[0030] The positioning frame 4 is fixed on both sides of the construction surface through the piercing portion, and the positioning frame 4 fixes both ends of the roller 2 through the clamping member 3. The detachable connection method of the clamping member 3 facilitates construction workers to replace the roller 2 and the membrane cloth 1. The clamping member 3 can slide along the side of the positioning frame 4, and the height of the clamping member 3 is adjusted through the adjusting assembly, and the height of the roller 2 can also be adjusted to ensure that the membrane cloth 1 can always be in close contact with concrete tabletops of different heights, with better applicability.
[0031] Specifically, the clamping member 3 includes a lower support base 31 and an upper pressing base 32. The lower support base 31 is placed below the upper pressing base 32. The lower support base 31 passes through the positioning frame 4 and is slidably connected to the positioning frame 4. An arc-shaped card slot for placing the roll 2 is provided on the side of the lower support base 31 and the upper pressing base 32 that are close to each other. A bolt connecting member is provided at the upper end of the lower support base 31 for closing the upper pressing base 32 on the upper end of the lower support base 31.
[0032] By adjusting the height of the upper pressing base 32 through the bolt connecting member and opening the upper pressing base 32 and the lower support base 31, the roll 2 can be placed in the arc-shaped card slot between the lower support base 31 and the upper pressing base 32. Then, by adjusting the height of the upper pressing base 32 again through the bolt connecting member, the upper pressing base 32 falls. After the upper pressing base 32 falls, it will close on the upper end of the lower support base 31, and the roll 2 will not detach from between the lower support base 31 and the upper pressing base 32, making the disassembly, installation, and replacement of the roll 2 convenient.
[0033] More specifically, the bolt connecting member includes an adjusting bolt 33. The adjusting bolt 33 is assembled at one end of the upper pressing base 32 close to the positioning frame 4. The adjusting bolt 33 passes through the upper pressing base 32 and the lower support base 31 in sequence. The adjusting bolt 33 is rotatably connected to the upper pressing base 32 and is threadedly connected to the lower support base 31. A clamping structure that cooperates with the lower support base 31 is provided at the end of the upper pressing base 32 away from the adjusting bolt 33. Rotate the adjusting bolt 33 and screw the lower support base 31 upward into the upper pressing base 32 and below the lower support base 31. The upper pressing base 32 moves closer to the lower support base 31 to fix the roll 2. When the lower support base 31 and the upper pressing base 32 are aligned, the clamping structure at the other end of the upper pressing base 32 will cooperate with the lower support base 31 to prevent the upper pressing base 32 from continuing to rotate after it falls.
[0034] It is worth further explaining that the clamping structure includes a protruding portion 34. The protruding portion 34 is fixedly connected to the lower end surface of the upper pressing base 32. The protruding portion 34 is engaged with a groove 35 opened at the upper end of the lower support base 31. After the upper pressing base 32 falls on the upper end of the lower support base 31, the protruding portion 34 at the lower end of the upper pressing base 32 will be stuck into the groove 35 at the upper end of the lower support base 31 to limit the rotation of the upper pressing base 32.
[0035] Regarding the adjusting assembly:
[0036] The adjusting assembly includes a limiting rod 44 and a threaded rod 42. The limiting rod 44 is rotatably connected to the inside of the positioning frame 4. The threaded rod 42 is rotatably connected to the inside of the positioning frame 4. The limiting rod 44 and the threaded rod 42 pass through the lower support base 31. The limiting rod 44 is slidably connected to the lower support base 31. The upper pressing base 32 is threadedly connected to the lower support base 31. A first rotating head 43 is provided at the upper end of the positioning frame 4. The first rotating head 43 is fixedly connected to the upper end of the threaded rod 42.
[0037] The adjustment component is a common screw drive component. When the first rotating head 43 is rotated, the first rotating head 43 will drive the threaded rod 42 to rotate. During the rotation of the threaded rod 42, it cooperates with the lower support base 31 to push the lower support base 31 to move along the rod body of the threaded rod 42. When the threaded rod 42 moves, it will also move along the rod body of the limit rod 44. The limit rod 44 guides the lower support base 31 through cooperation with the lower support base 31.
[0038] Regarding the puncture part:
[0039] The puncture part includes a second rotating head 45 provided at the upper end of the positioning frame 4 and a puncture cone 46 provided at the lower end of the positioning frame 4. The second rotating head 45 is fixedly connected to the upper end of the limit rod 44, and the puncture cone 46 is fixedly connected to the lower end of the limit rod 44. Threaded teeth 41 are provided on the outer side of the puncture cone 46.
[0040] When the second rotating head 45 is rotated, the puncture cone 46 at the lower end of the positioning frame 4 will rotate under the drive of the limit rod 44 inside the positioning frame 4. During the rotation of the puncture cone 46, it will screw into the soil on both sides of the concrete table or the holes of the plate member through the threaded teeth 41 on its outer side to fix the position of the positioning frame 4.
[0041] The working principle of this application:
[0042] After the concrete tabletop is poured, it will be cured by watering, and the film cloth 1 is laid on the construction surface to ensure the humidity of the construction surface. The positioning frame 4 is fixed on both sides of the construction surface through the puncture part, and the positioning frame 4 fixes both ends of the roller 2 through the clamping member 3. The detachable connection method of the clamping member 3 facilitates the construction personnel to replace the roller 2 and the film cloth 1. The clamping member 3 can slide along the side of the positioning frame 4, and the height of the clamping member 3 is adjusted through the adjustment component, and the height of the roller 2 can also be adjusted to ensure that the film cloth 1 can always be in close contact with the concrete tabletop with different heights, and the applicability is better.
