Description

Technical Field

[0001] The invention relates to the field of concrete curing, and in particular to a concrete curing device for building construction. Background Art

[0002] After concrete is poured, there is still a lot of water in the concrete. When the water in the concrete evaporates too quickly, dehydration will occur, causing the formed concrete to crack and break. Therefore, the concrete must be cured after pouring. The method is to cover the concrete with felt, etc., and then sprinkle water along the felt to keep the straw mat moist. However, it is difficult to move the felt manually when covering it, and the length of the straw mat directly affects the difficulty of sprinkling water when sprinkling water along the felt. The existing concrete curing device is to automatically sprinkle water on the concrete through a sprinkler truck. Although the labor intensity of the staff when sprinkling water is reduced, direct sprinkling water will cause impact on the concrete and damage the surface structure of the concrete.

[0033] In a specific embodiment: after the felt 7 is used, the hand wheel 9 is turned to make the second gear 10 drive the first gear 8 to rotate, so that the mounting shaft 6 rewinds the felt 7. At the same time, the second gear 10 drives the third gear 18 to rotate, and the third gear 18 is moved downward through the first slide groove 17, so that the squeezing roller 16 and the first support roller 14 squeeze the felt 7 to be rewound on the first support roller 14, so that the residual water in the felt 7 can be squeezed out and dropped, and then discharged through the drainage groove 25, thereby reducing the overall weight and facilitating transportation.

[0034] like Figure 3 and Figure 4 As shown, the concrete curing device for construction includes a traction device, which includes a card plate 28, a connecting rod 29, a connecting roller 30, a second movable component 31 and a buckle 34. A connecting rod 29 is provided between the card plates 28. The card plates 28 are mounted on the lower end of the vehicle body 1 through the buckle 34. The connecting roller 30 is rotatably mounted on the connecting rod 29. One end of the felt 7 is fixed on the connecting roller 30. One end of the second movable component 31 is rotatably mounted on the outer side of the card plate 28. The buckle 34 is fixed to the inner side of the lower end of the vehicle body 1.

[0035] In a specific embodiment: when laying the felt 7, the handle 2 is used to push and pull the vehicle body 1, so that the vehicle body 1 is moved through the first moving assembly 3 and the steering assembly 4. After moving to the position where it needs to be used, the buckle 34 is opened to separate the card plate 28 from the vehicle body 1, and then the vehicle body 1 is pulled, and the hand wheel 9 is turned at the same time to loosen the felt 7. At the same time, the hand wheel 9 causes the second gear 10 to drive the third gear 18 to rotate, and the third tooth moves up through the first slide groove 17, so that the squeezing roller 16 is away from the first support roller 14, so that the vehicle body 1 is moved while the felt 7 is laid between the vehicle body 1 and the card plate 28.

[0036] like Figure 3 , Figure 5 and Figure 6 As shown, the concrete curing device for construction includes a sprinkler, which includes a water tank 19, a slide plate 20, a clamping ring 21 and a guide plate 23. The water tank 19 is fixed on the vehicle body 1 and is located above the squeezing roller 16. A connecting port is provided above the water tank 19 for connecting to an external water source. The slide plate 20 is slidably installed below the water tank 19. The lower end of the water tank 19 fits the shape of the slide plate 20. A cavity 22 is opened on the slide plate 20. Openings are provided on both sides of the upper end of the slide plate 20 to connect the cavity 22. A slit is provided at the lower end of the slide plate 20 to connect the cavity 22. The clamping ring 21 is provided below the slide plate 20. The clamping ring 21 is sleeved on both ends of the squeezing roller 16. The guide plate 23 is tilted and fixed on the vehicle body 1 and is located behind the water tank 19. The lower end of the guide plate 23 is located above the first support roller 14 and the second support roller 15. The guide plate 23 is provided with staggered protrusions 24.

[0037] In a specific embodiment: when laying the felt 7, the extrusion roller 16 is moved upward, so that the slide plate 20 is moved upward through the retaining ring 21, so that the upper end of the slide plate 20 enters above the water tank 19, and the water flows into the cavity 22 through the openings on both sides of the upper end of the slide plate 20, and is thus sprayed out from the slit at the lower end of the slide plate 20. The sprayed water will fall on the inclined guide plate 23, and the protrusion 24 on the guide plate 23 will slow down and disperse the water flow, thereby evenly wetting the felt 7 below.

[0038] like Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the concrete curing device for construction includes a pressing device, which includes a first counterweight block 26, a second counterweight block 32 and a toggle rod 33. The first counterweight block 26 is slidably arranged at the lower end of the vehicle body 1, and a corresponding second slide groove 27 is arranged on the vehicle body 1. The second counterweight block 32 is connected to the inner side of the second movable component 31 through connecting rods 29 arranged at both ends. A toggle rod 33 is rotatably arranged above the second counterweight block 32. The two ends of the toggle rod 33 are protruding, and the edge of the block is provided with a rounded corner and a groove connected to the rounded corner. The first counterweight block 26 and the second counterweight block 32 are provided with a through hole that fits the felt 7 for installing the felt 7.

[0039] In a specific embodiment: when the card plate 28 is separated from the vehicle body 1, the first counterweight block 26 slides to the bottom of the second slide groove 27 due to gravity, and then the toggle rod 33 is rotated to disengage the toggle rod 33 from the groove above the card plate 28 and rotate to the rear of the card plate 28, and then the toggle rod 33 and the second counterweight block 32 are pressed down, and the second movable assembly 31 is pushed to rotate through the connecting rod 29, so that the second movable assemblies 31 on both sides become an "eight" shape, thereby preventing the movement of the card plate 28. At the same time, the first counterweight block 26 and the second counterweight block 32 lower the position of the felt 7, thereby limiting the felt 7 and assisting in the laying of the felt 7.

[0040] Working principle: When in use, the handle 2 is used to push and pull the vehicle body 1, so that the vehicle body 1 moves through the first moving assembly 3 and the steering assembly 4. After moving to the position to be used, the buckle 34 is opened to separate the card plate 28 from the vehicle body 1, and then the toggle rod 33 and the second counterweight block 32 are pressed down, and the second moving assembly 31 is pushed to rotate through the connecting rod 29, so that the second moving assemblies 31 on both sides become an "eight" shape, thereby preventing the movement of the card plate 28, and then the vehicle body 1 is pulled, and the hand wheel 9 is turned at the same time to loosen the felt 7. At the same time, the hand wheel 9 drives the second gear 10 to drive the third gear 18 to rotate, and the third tooth moves up through the first slide groove 17, so that the squeezing roller 16 is away from the first support roller 14, so that As the vehicle body 1 moves, the felt 7 is laid between the vehicle body 1 and the cardboard 28, and then the extrusion roller 16 moves upward, so that the slide plate 20 moves upward through the snap ring 21, so that the upper end of the slide plate 20 enters above the water tank 19, and the water flows into the cavity 22 through the openings on both sides of the upper end of the slide plate 20, and is thus sprayed out from the slit at the lower end of the slide plate 20. The sprayed water will fall on the inclined guide plate 23, and the water flow will be decelerated and dispersed through the protrusions 24 on the guide plate 23, so as to evenly wet the felt 7 below. When the cardboard 28 is separated from the vehicle body 1, the first counterweight block 26 slides to the bottom of the second slide groove 27 due to gravity, thereby limiting the felt 7 together with the second counterweight block 32 to assist in the laying of the felt 7.

[0041] During recycling, the hand wheel 9 is turned to make the second gear 10 drive the first gear 8 to rotate, so that the mounting shaft 6 rewinds the felt 7. At the same time, the second gear 10 drives the third gear 18 to rotate, and the third gear 18 is moved downward through the first slide groove 17, so that the squeezing roller 16 and the first supporting roller 14 squeeze the felt 7 to be rewound on the first supporting roller 14, so that the residual water in the felt 7 can be squeezed out and fall, and then discharged through the drainage groove 25.
