Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a water-saving concrete humidity maintaining device for building construction. Background Technique

[0002] During the initial setting and hardening process of concrete, water is required to complete the hydration reaction. Maintaining appropriate humidity is beneficial to the development of concrete strength. Premature loss of water in concrete will lead to shrinkage and cracks. Maintaining humidity can reduce the risk of shrinkage and cracks in concrete, reduce surface cracking and sanding, and improve the quality and durability of the concrete surface. Appropriate wet curing can improve the durability and service life of concrete and reduce maintenance and repair costs.

[0003] Currently, the commonly used method for maintaining the humidity of concrete is to cover the concrete with a moisture-retaining cloth. However, the covering and winding of the moisture-retaining cloth usually require multiple manual operations, which reduces the construction efficiency.

The device includes a heat and moisture preservation cloth, a mobile support frame, and a water sprinkling pipe. An adjustable support crossbeam is arranged on the upper part of the mobile support frame, and a rotating support assembly located above the adjustable support crossbeam is arranged on the mobile support frame. The heat and moisture preservation cloth is wound around the rotating support assembly. An auxiliary cloth-releasing device is arranged on the left side of the mobile support frame. The auxiliary cloth-releasing device includes an upper pressure roller and a lower pressure roller. The upper pressure roller and the lower pressure roller are arranged up and down below the left side of the mobile support frame. The water sprinkling pipe is arranged on the mobile support frame and is located on the left side of the upper pressure roller and the lower pressure roller. However, this device has some defects: after laying the moisture-retaining cloth, it is necessary to use a water sprinkling pipe to sprinkle water on the moisture-retaining cloth to soak it. However, this method requires a large amount of water, resulting in waste of water resources. Content of the Utility Model

[0023] Please refer to Figure 1 、 Figure 2 、 Figure 3 , the present utility model provides a technical solution: a water-saving concrete humidity-keeping device for building construction, including a moisture-holding cloth 1, a winding shaft 2 fixedly connected to the fixed end of the moisture-holding cloth 1, and a moving frame 3 rotatably connected to the winding shaft 2. A support plate 41 is fixedly connected to the moving frame 3. A water tank 4 is fixedly connected to the lower end of the support plate 41. Two groups of support plates 41 are symmetrically fixedly connected to both ends of the water tank 4. A limiting roller 42 is rotatably connected to the inner side wall of the water tank 4. The position of the limiting roller 42 is close to the bottom of the water tank 4. A first squeezing roller 43 and a second squeezing roller 44 are rotatably connected to the support plate 41. The first squeezing roller 43 and the second squeezing roller 44 are arranged on one side close to the output end of the limiting roller 42. The moisture-holding cloth 1 bypasses the limiting roller 42. The moisture-holding cloth 1 passes through the gap between the first squeezing roller 43 and the second squeezing roller 44. The gap between the first squeezing roller 43 and the second squeezing roller 44 is equal to or slightly larger than the thickness of the moisture-holding cloth 1.

[0024] After the moisture-holding cloth 1 absorbs water, it will slightly expand. After passing through the gap between the first squeezing roller 43 and the second squeezing roller 44, the excess water will be left in the water tank 4.

[0025] The movable frame 3 includes symmetrically arranged sleeves 31, extension rods 32 inserted into the sleeves 31, support columns 33 fixedly connected to both the sleeves 31 and the extension rods 32, and moving wheels 34 fixedly connected to the lower ends of the support columns 33. A telescopic support frame 35 is arranged between the horizontally arranged support columns 33. The winding shaft 2 is rotatably connected to the sleeve 31. The support plate 41 is fixedly connected to the sleeve 31. A positioning pin 36 is inserted through the sleeve 31, and the positioning pin 36 passes through the sleeve 31 and the extension rod 32.

[0026] In this embodiment, the telescopic support frame 35 adopts a scissor telescopic frame, and the longitudinally arranged support columns 33 are fixedly connected through connecting columns 39.

[0027] A first compression roller 51 and a second compression roller 52 are rotatably connected to the support plate 41. The first compression roller 51 and the second compression roller 52 are arranged on one side close to the input end of the limit roller 42. The moisture-proof cloth 1 passes through the gap between the first compression roller 51 and the second compression roller 52, and the gap between the first compression roller 51 and the second compression roller 52 is smaller than the thickness of the moisture-proof cloth 1.

[0028] The moisture-proof cloth 1 first passes through the gap between the first compression roller 51 and the second compression roller 52, then bypasses the limit roller 42, and then passes through the gap between the first extrusion roller 43 and the second extrusion roller 44.

[0029] The winding shaft 2 is drivingly connected to a driving motor 6 that drives its rotation, and the driving motor 6 is fixedly connected to the sleeve 31.

[0030] A drain hole is opened at the lower end of the water tank 4, and a sealing plug 7 is arranged on the drain hole.

[0031] When the device is in use, the staff first pulls out the positioning pin 36, then pulls the front support column, the extension rod 32 and the telescopic support frame 35 extend, and then the staff inserts the positioning pin 36 back; next, the staff stores water in the water tank 4, the staff slowly moves the free end of the moisture-proof cloth 1, fixes the free end of the moisture-proof cloth 1 on the concrete to be laid, and then the staff starts the driving motor 6, the winding shaft 2 rotates forward at a low speed, the moisture-proof cloth 1 is released from the winding shaft 2, and then the staff pushes the device to move until the laying is completed;

[0032] When the moisture-proof cloth 1 needs to be wound up, the staff first stores water in the water tank 4. The moisture-proof cloth 1 to be wound passes through the water tank 4 to clean the moisture-proof cloth 1. The moisture-proof cloth 1 then passes through the first compression roller 51 and the second compression roller 52 and is squeezed by the first compression roller 51 and the second compression roller 52 to discharge most of the water. The staff then pulls out the moisture-proof cloth 1 to dry it, and finally winds up the moisture-proof cloth 1 for storage.
