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

[0002] In construction, the reason why concrete can gradually solidify and harden after pouring is mainly due to the hydration of cement, and hydration requires appropriate temperature and humidity conditions.

[0032] Compared with the prior art, the concrete curing device for building construction provided by the present invention has the following beneficial effects:

[0033] 1. When the carrier moves, the film roller rotates accordingly, releasing the film so that it covers the building floor that has just been sprayed with water.

During the rotation process, the film is attached to the building floor through the action of water, which effectively prevents the rapid evaporation of water and can continuously maintain the concrete building floor;

[0034] 2. When the carrier moves on the inclined building ground, the guide tube on the side tilted downward is automatically controlled to open, so that the sand and soil can flow smoothly into the conveying tube and the discharge pipe on the side tilted downward. The sand and soil discharged through the discharge pipe fall on the edge of the membrane in a straight line as the carrier moves, so that the membrane and the concrete building ground fit more closely, the water inside the membrane is blocked, and the amount of water inside the membrane flowing out due to the tilt of the building ground is reduced, thereby improving the continuous maintenance effect of the inclined concrete building ground;

[0035] 3. The greater the inclination of the concrete building ground, the larger the connection area between the guide groove and the guide tube. The larger the connection area, the faster the sand passes through. Therefore, the more sand is put on the membrane, the more the membrane edge can be compacted, reducing water loss. Conversely, the smaller the inclination of the concrete building ground, the less sand is put in, which can reduce the amount of sand used. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0045] Example: See Figure 1 - Figure 5 A concrete curing device for construction includes a carrier 1 and a plurality of rollers 2 mounted at the bottom of the carrier 1, a damping spring capable of reflecting a position difference is arranged between the rollers 2 and the bottom of the carrier 1, so that when the carrier 1 moves on an inclined construction ground, the roller 2 on the side inclined downward is subjected to a greater gravity, so that the damping spring connected to the roller 2 is compressed to a greater extent, and the perception of the horizontality of the construction ground is more obvious, wherein the concrete construction ground is a concrete pavement, and the concrete curing device for construction also includes:

[0046] A watering maintenance mechanism is installed on the carrier 1 and is used to evenly spray water onto the concrete building floor. The watering maintenance mechanism includes a shunt pipe 3 installed on the outer wall of one side of the carrier 1 and a plurality of nozzles 4 installed at the bottom of the shunt pipe 3. A water pump and a water tank are installed inside the carrier 1. One end of the water pump is connected to the water tank, and the other end of the water pump is connected to the shunt pipe 3.

[0047] When the vehicle 1 is moving, the water in the water tank is pumped out to the diversion pipe 3 by starting the water pump, and the water is evenly sprayed out through each nozzle 4 .

[0048] The film-coating and water-locking mechanism is installed on the carrier 1 and is used to lay the film after sprinkling water on the concrete building floor, and make the film and the concrete building floor fit closely together. The film-coating and water-locking mechanism includes a bracket 5 installed on the top of the carrier 1 and a pressure roller 6 arranged on one side of the shunt pipe 3. The bracket 5 and the carrier 1 are connected by bolts, that is, the bracket 5 can be removed from the carrier 1; a rotating roller 7 is installed inside the bracket 5, and the rotating roller 7 can be removed from the bracket 5 to facilitate the replacement of the film roller 8 outside the rotating roller 7, and the outer part of the rotating roller 7 is sleeved with the film roller 8; two linkage frames 9 are hinged on the outer wall of one side of the carrier 1, and the pressure roller 6 is rotatably connected between the two linkage frames 9; one end of the film on the film roller 8 passes through the bottom of the pressure roller 6;

[0049] When the operation is just started, the staff will first fix one end of the film. When the carrier 1 moves, the film roller 8 will rotate accordingly to release the film, so that the film covers the building floor that has just been sprayed with water. At the same time, the pressure roller 6 is affected by its own gravity. During the rotation process, the film is attached to the building floor through the action of water, which effectively prevents the rapid evaporation of water and can continuously maintain the concrete building floor.

[0050] A horizontal sensing mechanism is installed at the bottom of the carrier 1 to sense the change in the level of the concrete building ground. There are two horizontal sensing mechanisms, which include a movable seat 10 arranged at the bottom of the carrier 1 and a sphere 11 rollingly connected to the bottom of the movable seat 10; a slide bar 12 is installed on the top of the movable seat 10, and the slide bar 12 runs through the carrier 1 and is slidably connected to the carrier 1;

[0051] When the vehicle 1 moves on the inclined building ground, the roller 2 on the inclined downward side is subjected to a greater gravity, and thus the damping spring connected to the roller 2 is compressed to a greater extent. As a result, the distances between the rollers 2 on both sides and the bottom of the vehicle 1 become different. The roller 2 on the inclined downward side is closer to the bottom of the vehicle 1, and therefore the sphere 11 on the inclined downward side approaches the vehicle 1, and the slide bar 12 moves upward accordingly. The roller 2 on the inclined upward side is subjected to a reduced gravity, which increases the distance between the roller 2 and the vehicle 1, and thus the corresponding slide bar 12 moves downward. However, the slide bar 12 still closes the guide tube 19 when it moves downward, that is, only when the slide bar 12 moves upward can the guide tube 19 be controlled to be connected to the conveying tube 15.

[0052] The material feeding and blocking mechanism is installed on the top of the carrier 1 and connected to the horizontal sensing mechanism, and is used to transport sand and soil in a straight line to the top of the membrane located on the inclined downward side of the concrete building ground. A sand box 13 is installed on the top of the carrier 1, and a main flow cylinder 14 is installed at the bottom of the sand box 13. There are two material feeding and blocking mechanisms, and the two material feeding and blocking mechanisms are symmetrically arranged on both sides of the main flow cylinder 14; the material feeding and blocking mechanism includes a conveying cylinder 15 installed on the top of the carrier 1 and a discharge pipe 16 installed at one end of the conveying cylinder 15; the conveying cylinder 15 is rotatably connected with an auger 17, and the other end of the conveying cylinder 15 is installed with a motor 18, and the output end of the motor 18 is fixedly connected to one end of the auger 17; the other end of the discharge pipe 16 is arranged to be inclined downward;

[0053] The motor 18 always keeps running. When the sand in the sand box 13 enters the corresponding conveying cylinder 15 through the main cylinder 14 and the guide cylinder 19, the auger 17 in the rotation process conveys the sand to the inside of the discharge pipe 16. The sand discharged through the discharge pipe 16 falls on the edge of the membrane in a straight line as the carrier 1 moves, so that the membrane fits more closely with the concrete building floor, the water inside the membrane is blocked, the amount of water inside the membrane flowing out due to the tilt of the building floor is reduced, and the maintenance effect on the concrete building floor is improved.

[0054] A control mechanism is installed on the carrier 1 and is respectively connected to the horizontal sensing mechanism and the material feeding blocking mechanism to control the release time and release amount of sand and soil. Two control mechanisms are provided, and the two control mechanisms are respectively connected to the two conveying cylinders 15. The control mechanism includes a guide cylinder 19 connected to the main flow cylinder 14, a through groove 20 provided inside the guide cylinder 19, and a guide groove 21 penetrating through the inside of the slide bar 12; the other end of the guide cylinder 19 is connected to the top of the conveying cylinder 15; the slide bar 12 is provided with the through groove 20, dividing the guide cylinder 19 into two, and when the guide groove 21 is connected to the inside of the guide cylinder 19, the sand and soil inside the sand box 13 enters the inside of the conveying cylinder 15 through the main flow cylinder 14 and the guide cylinder 19;

[0055] When the slide bar 12 moves upward, the guide groove 21 inside it moves upward synchronously, and the guide groove 21 is then connected to the inside of the guide cylinder 19, and the sand inside the guide cylinder 19 enters the inside of the conveying cylinder 15 through the guide groove 21;

[0056] The area of ​​connection between the guide groove 21 and the guide tube 19 is determined by the degree of inclination of the concrete building ground. That is, the greater the inclination of the concrete building ground, the larger the connection area between the guide groove 21 and the guide tube 19. The larger the connection area, the faster the sand passes through. Therefore, the more sand is put on the membrane, the more the membrane edge can be compacted, and the water loss can be reduced. On the contrary, the smaller the inclination of the concrete building ground, the less sand is put in, and the amount of sand used can be reduced.

[0057] Sealing blocks 22 are provided on both sides of the slide bar 12. The sealing blocks 22 are fixedly connected to the outside of the guide tube 19 to seal the guide groove 21.

[0058] When half of the area of ​​the guide groove 21 is connected to the guide tube 19, the sand will enter the guide groove 21 when passing through the guide tube 19. The setting of the sealing block 22 can prevent the sand from being scattered when entering the guide groove 21. After the sand enters the guide groove 21, the part of the guide groove 21 that is not connected to the guide tube 19 will be filled up, and then flow into the conveying tube 15 along the space connected between the guide groove 21 and the guide tube 19.

[0059] A limit block 23 is provided above the slide bar 12, and the limit block 23 is fixedly connected to the bottom of the sand box 13; a slide groove 24 is provided inside the movable seat 10, and a slide seat 25 is slidably connected inside the slide groove 24, and a return spring 26 is fixedly connected to the bottom of the slide seat 25, and the bottom end of the return spring 26 is fixedly connected to the inner wall of the bottom of the slide groove 24. The return spring 26 is provided to facilitate the reset of the slide seat 25. The bottom end of the slide bar 12 extends to the inside of the slide groove 24 and is fixedly connected to the top of the slide seat 25;

[0060] When the slide bar 12 moves upward to make the guide groove 21 fully connected with the guide tube 19, that is, when the maximum flow area of ​​the guide groove 21 is reached, the top of the slide bar 12 abuts against the bottom of the limit block 23, so the slide bar 12 will not continue to move upward, so that the guide groove 21 remains at the maximum flow area. In the current situation, if the carrier 1 continues to tilt, the slide bar 12 will drive the slide seat 25 to move downward along the inner wall of the slide groove 24 to compensate for the position difference caused by the continued tilt.

[0061] Working principle: When in use, one end of the film on the film roller 8 passes through the bottom of the pressure roller 6. The staff first fixes one end of the film. When the carrier 1 moves, the water in the water tank is pumped into the shunt pipe 3 by starting the water pump, and is evenly sprayed out through each nozzle 4. When the carrier 1 moves, the film roller 8 rotates accordingly to release the film so that the film covers the building ground that has just been sprayed with water. At the same time, the pressure roller 6 is affected by its own gravity. During the rotation process, the film is attached to the building ground through the action of water, which effectively prevents the rapid evaporation of water and can continuously maintain the concrete building ground. When the carrier 1 moves on the inclined building ground, the roller 2 on the inclined downward side is subjected to a greater gravity, so the damping spring connected to the roller 2 is compressed to a greater extent, so the distance between the rollers 2 on both sides and the bottom of the carrier 1 is The distance becomes different, the roller 2 tilted downward is closer to the bottom of the carrier 1, so the sphere 11 tilted downward approaches the carrier 1, and the slide bar 12 moves upward. When the slide bar 12 moves upward, it drives the guide groove 21 inside it to move upward synchronously, and the guide groove 21 is then connected with the inside of the guide cylinder 19, and the sand and soil inside the guide cylinder 19 enters the inside of the conveying cylinder 15 through the guide groove 21. The auger 17 in the rotation process transports the sand and soil to the inside of the discharge pipe 16, and the sand and soil discharged through the discharge pipe 16 falls on the edge of the membrane in a straight line as the carrier 1 moves, so that the membrane and the concrete building floor fit more closely, the water inside the membrane is blocked, and the amount of water inside the membrane flowing out due to the tilt of the building floor is reduced, thereby improving the maintenance effect on the concrete building floor.
