Description

Technical Field

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

[0002] Concrete is a general term for engineering composite materials that are made of cementitious materials that bind aggregates together. After pouring, concrete needs to be cured. The gradual hardening and strength increase of concrete is the result of cement hydration, and cement hydration requires certain temperature and humidity conditions. If the surrounding environment lacks these conditions, concrete needs to be cured manually.

[0003] Traditional concrete curing generally adopts the method of manual pouring. After the concrete is poured, watering curing usually begins within 8 to 12 hours. The length of curing time varies according to factors such as ambient temperature, cement type and concrete mix ratio; and the curing time after concrete pouring is generally 7 days. This 7-day curing period is to ensure that the concrete can achieve sufficient strength and stability. For concrete with added retarders or other special requirements, the curing time may need to be extended to 14 days, which is very labor-intensive and material-intensive.

[0004] In the prior art, a Chinese patent with a publication number of CN211306774U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: it includes a bottom plate and a water storage tank placed on the ground, characterized in that a plurality of mounting blocks are provided at the lower end of the bottom plate, a rotating wheel is installed at the lower end of the plurality of mounting blocks, a rotating shaft is fixedly connected between each two rotating wheels, a strip cavity is provided in the bottom plate, a water storage chamber is provided in the water storage tank, a water inlet is provided on one side wall of the water storage chamber, two nozzles are rotatably connected in the strip cavity, the water spraying ports of the two nozzles both penetrate the inner bottom of the strip cavity, a water injection mechanism for injecting water into the nozzle is provided in the water storage chamber, and a swing mechanism for swinging the nozzle is provided in the strip cavity. The curing device only needs one worker to push the bottom plate to move to sprinkle water, which improves the efficiency of curing. However, when a manual pushing device is used for curing, the strength of the concrete is not enough to support the weight of the person and the curing device after the concrete is just poured, so it is not very suitable, and the concrete needs to be coated during curing to reduce the evaporation of concrete water. Utility Model Content

[0005] The purpose of the utility model is to provide a concrete curing device for building construction to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a concrete curing device for construction, comprising an electric rail, a gantry and a body; the gantry is slidably connected to the electric rail, and the electric rail can drive the gantry to slide on the electric rail; a crossbeam is fixed on the gantry, a slide rail is fixed on the crossbeam, and a slide table is slidably provided on the slide rail;

[0007] The main body includes a chassis and a fixed plate, which are fixedly connected to the chassis; a water leakage groove is provided at the upper end of the chassis, a leakage hole is provided on the water leakage groove, a water tank is provided on one side of the water leakage groove, and a floating groove is provided on the other side, a floating port is provided on the floating groove close to the water leakage groove, and the floating hole is communicated with the water leakage groove; a water outlet is provided on the side of the water leakage groove close to the water tank, and the water outlet is communicated with the water tank; a water stop component is provided on the water leakage groove, and the water stop component is used to open and close the water outlet; a fixed block is fixedly provided on the side of the chassis close to the leakage hole, a coating roller is rotatably connected to the fixed block, and a coating film is rolled up on the coating roller.

[0008] When concrete needs to be cured after pouring, before curing, first install the electric rails on both sides of the concrete, then install the gantry on the slide rails, and then fix the main body to the movable end of the cylinder on the gantry; during curing, add enough water to the water tank, and the water in the water tank enters the leakage trough through the water outlet. As the gantry moves, the main body moves, and the water in the leakage trough leaks out from the leakage hole to moisten the concrete under the main body. By setting a water-stop component, the water volume is regulated, so that the water volume in the leakage trough remains stable, the speed at which the water falls from the leakage hole remains stable, and the curing of each part of the concrete is uniform, thereby improving the curing effect; before curing, it is also necessary to The film on the coating roller is fixed to one end of the concrete, and the film passes between the pressure roller and the coating roller. The film is tangent to the lower end of the pressure roller. When the gantry moves, the coating roller rotates out the film to cover the concrete, reducing the evaporation of water, protecting the concrete surface, and improving the curing effect. When water leaks from the leaking trough, if the concrete has not been completely formed, the water flow may impact the concrete surface and form small pits on the concrete surface. In some engineering projects with higher requirements, the concrete surface needs to be flat. The concrete surface can be pressed by the pressure roller to flatten the concrete surface and press the film, so that the film can better fit the concrete.

[0009] A further improvement of the technical solution of the utility model is that a damping shaft is fixedly provided on the fixed plate, the movable end of the cylinder is fixedly connected to the damping shaft, and the damping shaft is rotationally connected to the fixed plate.

[0010] With the above technical solution, when the position of the main body needs to be adjusted or repaired, the damping shaft can be easily rotated, so that the main body can be flexibly adjusted to various angles. This flexible rotation performance not only greatly simplifies the operation process, but also improves work efficiency. During the adjustment or maintenance process, the main body is adjusted to a suitable position, and the damping shaft can be automatically locked to prevent the main body from moving or changing when unattended. This greatly improves the stability and safety of the work and avoids various interferences and accidents that may be caused by the unfixed main body.

[0011] A further improvement of the technical solution of the utility model is that the water-stopping component includes a connecting rod, one end of the connecting rod is fixedly connected to a baffle, the other end is fixedly connected to a floating plate, the baffle is slidably connected to the water outlet, and the floating plate is slidably connected to the outlet.

[0012] The above technical scheme is adopted. By setting a floating plate, the water in the water tank will enter the leakage trough through the water outlet. The leakage trough is connected with the floating trough through the floating hole. When the water level in the leakage trough is higher than the leakage hole, the water in the leakage trough will enter the floating trough through the floating hole, so that the water level of the floating trough is consistent with the water level of the leakage trough. When the water level rises, the floating plate rises with the rising water level, thereby driving the baffle to rise and close the water outlet to keep the water level fixed. When the water level drops, the baffle is driven to drop so that the water in the water tank can re-enter the leakage trough to maintain the water level.

[0013] A further improvement of the technical solution of the utility model is that a hinge is symmetrically fixed on one side of the chassis close to the laminating roller, a support arm is hinged on the hinge, and a hinge shaft hole is provided at one end of the support arm; a pressure roller is provided between the two support arms, and the pressure roller is rotatably connected to the support arm.

[0014] The above technical solution is adopted, in which a hinge is set between the pressure roller and the hinge. When encountering concrete of different heights, when the cylinder drives the main body to rise too high or too low, the pressure roller can be adjusted through the hinge to prevent the pressure roller from failing to contact the concrete surface.

[0015] A further improvement of the technical solution of the utility model is that the articulated part includes a fixing part, which is fixedly connected to the side of the chassis, and a hinge port is provided on the fixing part, and an articulated rod passes through the hinge port, and the articulated rod is fixedly connected to the support arm, a handle is fixedly provided at one end of the articulated rod, and a limit part is fixedly provided at the other end, and the limit part is used to limit and fix the articulated rod.

[0016] The above-mentioned technical scheme is adopted, in which the fixing part is fixedly connected to the side of the chassis to support the whole, and the hinged rod passes through the hinge interface, a handle is provided at one end for rotation and adjustment, and a limiter is provided at the other end for fixing the position; when the position of the pressure roller needs to be adjusted, the handle is turned to adjust the angle of the support arm and then the position of the pressure roller is adjusted. When the position of the pressure roller is determined, the hinged rod is fixed by the limiter to prevent the pressure roller from shifting.

[0017] A further improvement of the technical solution of the utility model is that the limiting member includes a limiting block, which is a cube, a movable groove is opened on the side of the chassis close to the limiting block, a groove block is slidably provided on the movable groove, and the groove shape of the groove block matches the shape of the limiting block.

[0018] The above technical solution is adopted. In this solution, after the position of the pressure roller is determined, the slot block on the sliding movable slot is moved toward the limit block, and the limit block is inserted into the slot of the slot block. Because the slot block is square in shape, the limit block cannot rotate in the slot of the slot block, thereby achieving the limitation of the movable slot.

[0019] A further improvement of the technical solution of the utility model is that a portion of the bottom surface of the water leakage groove close to the coating roller is a horizontal surface, a side close to the water outlet is an inclined surface, and the leakage hole is arranged on the horizontal surface.

[0020] The above technical solution is adopted, in which a part of the bottom surface of the drainage trough close to the coating roller is set as a horizontal plane, and the side close to the water outlet is set as an inclined plane. When the water in the water tank flows out from the water outlet, it will gather at the bottom surface of the drainage trough, so that the water can flow out better.

[0021] A further improvement of the technical solution of the utility model is that a cylinder is fixedly connected below the slide, and a movable end of the cylinder is fixedly connected to the body.

[0022] By adopting the above technical solution, in different construction conditions, the height of concrete pouring is also different. By setting a cylinder, the distance between the main body and the concrete surface is adjusted according to the height of different concrete.

[0023] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0024] 1. The utility model provides a concrete curing device for construction. By setting a water-stopping component, the water volume is regulated, so that the water volume in the leakage groove is kept stable, the speed of water falling from the leakage hole is kept stable, and the curing of each part of the concrete is uniform; the coating roller rotates out the coating to cover the concrete, reduce the evaporation of water, and protect the concrete surface; the pressing roller presses the concrete surface to flatten the concrete surface, and can also press the coating to fit the concrete to improve the curing effect.

[0025] 2. The utility model provides a concrete curing device for construction. By setting a hinge between a pressure roller and a hinge, when encountering concrete of different heights, when the cylinder drives the main body to rise too high or too low, the pressure roller can be adjusted through the hinge to prevent the pressure roller from failing to contact the concrete surface.

[0026] 3. The utility model provides a concrete curing device for construction, by setting a part of the bottom surface of the drain trough close to the coating roller as a horizontal surface, and a side close to the water outlet as an inclined surface, the water in the water tank will gather at the bottom surface of the drain trough when flowing out from the water outlet, so that the water can flow out better.

DETAILED DESCRIPTION

[0035] The present invention is further described in detail below in conjunction with the embodiments:

[0036] Example 1

[0037] like Figure 1-5As shown, the utility model provides a concrete curing device for construction, comprising an electric rail 1, a gantry 2 and a body 3; the gantry 2 is slidably connected to the electric rail 1, and the electric rail 1 can drive the gantry 2 to slide on the electric rail 1; a crossbeam is fixed on the gantry 2, a slide rail 4 is fixed on the crossbeam, and a slide platform 5 is slidably provided on the slide rail 4;

[0038] The main body 3 includes a chassis 7 and a fixed plate 8, which are fixedly connected to the chassis 7; a water leakage groove 9 is provided at the upper end of the chassis 7, a leakage hole 10 is provided on the water leakage groove 9, a water tank 11 is provided on one side of the water leakage groove 9, and a floating groove 12 is provided on the other side, a floating port 13 is provided on the floating groove 12 close to the side of the water leakage groove 9, and the floating hole is communicated with the water leakage groove 9; a water outlet 14 is provided on the side of the water leakage groove 9 close to the water tank 11, and the water outlet 14 is communicated with the water tank 11; a water stop component is provided on the water leakage groove 9, and the water stop component is used to switch the water outlet 14; a fixed block 15 is fixedly provided on the side of the chassis 7 close to the leakage hole 10, a coating roller 16 is rotatably connected to the fixed block 15, and a coating roller 16 is rolled up with a coating.

[0039] In this embodiment, after the concrete is poured, it needs to be cured. Before curing, the electric rail 1 is first installed on both sides of the concrete, then the gantry 2 is installed on the slide rail 4, and then the main body 3 is fixedly connected to the movable end of the cylinder 6 on the gantry 2; during curing, a sufficient amount of water is added to the water tank 11, and the water in the water tank 11 enters the leakage groove 9 through the water outlet 14. As the gantry 2 moves, the main body 3 moves, and the water in the leakage groove 9 leaks out from the leakage hole 10 to moisten the concrete under the main body 3. By setting a water-stopping component, the water volume is regulated, so that the water volume in the leakage groove 9 remains stable, the speed at which the water falls from the leakage hole 10 remains stable, and the curing of each part of the concrete is uniform, thereby improving the curing effect. Before curing, the film on the coating roller 16 needs to be fixed to one end of the concrete, and the film passes between the pressure roller 23 and the coating roller 16, and the coating is tangent to the lower end of the pressure roller 23. When the gantry 2 moves, the coating roller 16 rotates out the coating to cover the concrete, thereby reducing the evaporation of water and protecting the concrete surface, thereby improving the curing effect. When water leaks out of the leakage groove 9, if the concrete has not been completely formed, the water flow may impact the concrete surface and form small pits on the concrete surface. In some engineering projects with higher requirements, the concrete surface needs to be flat. The concrete surface is pressed by the pressure roller 23 to flatten the concrete surface and press the coating so that the coating fits better with the concrete.

[0040] In this embodiment, preferably, a damping shaft 17 is fixedly provided on the fixed plate 8 , a movable end of the cylinder 6 is fixedly connected to the damping shaft 17 , and the damping shaft 17 is rotationally connected to the fixed plate 8 .

[0041] When the position of the body 3 needs to be adjusted or repaired, the damping shaft 17 can be easily rotated so that the body 3 can be flexibly adjusted to various angles. This flexible rotation performance not only greatly simplifies the operation process, but also improves work efficiency. During the adjustment or maintenance process, the body 3 is adjusted to a suitable position, and the damping shaft 17 can be automatically locked to prevent the body 3 from moving or changing when unattended. This greatly improves the stability and safety of the work and avoids various interferences and accidents that may be caused by the unfixed body 3.

[0042] Preferably, the water-stopping component includes a connecting rod 18, one end of which is fixedly connected to a baffle 19, and the other end is fixedly connected to a floating plate 20, the baffle 19 is slidably connected to the water outlet 14, and the floating plate 20 is slidably connected to the outlet.

[0043] By setting the floating plate 20, the water in the water tank 11 will enter the leakage trough 9 through the water outlet 14. The leakage trough 9 is connected with the floating trough 12 through the floating hole. When the water level in the leakage trough 9 is higher than the leakage hole, the water in the leakage trough 9 will enter the floating trough 12 through the floating hole, so that the water level of the floating trough 12 is consistent with the water level of the leakage trough 9. When the water level rises, the floating plate 20 rises with the rise of the water level, thereby driving the baffle 19 to rise and close the water outlet 14 to keep the water level fixed. When the water level drops, the baffle 19 is driven to drop so that the water in the water tank 11 can re-enter the leakage trough 9 to maintain the water level.

[0044] A cylinder 6 is fixedly connected below the slide 5 , and a movable end of the cylinder 6 is fixedly connected to the body 3 .

[0045] Under different construction conditions, the height of concrete pouring is also different. By setting the cylinder 6, the distance between the main body 3 and the concrete surface is adjusted according to the height of different concrete.

[0046] Example 2

[0047] On the basis of Example 1, the utility model provides a technical solution: preferably, a hinge 21 is symmetrically fixed on one side of the chassis 7 close to the coating roller 16, a support arm 22 is hinged on the hinge 21, and a hinge shaft hole is provided at one end of the support arm 22; a pressure roller 23 is provided between the two support arms 22, and the pressure roller 23 is rotatably connected to the support arm 22.

[0048] In this embodiment, by setting a hinge between the pressure roller 23 and the hinge 21, when encountering concrete of different heights, when the cylinder 6 drives the main body 3 to rise too high or too low, the pressure roller 23 can be adjusted through the hinge to prevent the pressure roller 23 from failing to contact the concrete surface.

[0049] Example 3

[0050] On the basis of Example 1, the utility model provides a technical solution: preferably, the hinged member 21 includes a fixing member 24, which is fixedly connected to the side of the chassis 7, and a hinge interface is provided on the fixing member 24, and an articulated rod 25 passes through the hinge interface, and the articulated rod 25 is fixedly connected to the support arm 22, and a handle 26 is fixedly provided at one end of the articulated rod 25, and a limiting member is fixedly provided at the other end, and the limiting member is used to limit and fix the articulated rod 25.

[0051] In this embodiment, the fixing member 24 is fixedly connected to the side of the chassis 7 to support the whole. The hinged rod 25 passes through the hinge port, and a handle 26 is provided at one end for rotation and adjustment, and a limiter is provided at the other end for fixing the position. When the position of the pressure roller 23 needs to be adjusted, the handle 26 is rotated to adjust the angle of the support arm 22 and then the position of the pressure roller 23 is adjusted. When the position of the pressure roller 23 is determined, the hinged rod 25 is fixed by the limiter to prevent the pressure roller 23 from shifting.

[0052] The limiting member includes a limiting block 27 which is a cube. A movable groove 28 is provided on the side of the chassis 7 close to the limiting block 27 . A groove block 29 is slidably provided on the movable groove 28 . The groove shape of the groove block 29 matches the shape of the limiting block 27 .

[0053] When the position of the pressure roller 23 is determined, the slot block 29 on the sliding movable slot 28 is moved toward the limit block 27, and the limit block 27 is inserted into the slot of the slot block 29. Since the slot block 29 is square in shape, the limit block 27 cannot rotate in the slot of the slot block 29, thereby achieving the limitation of the movable slot 28.

[0054] Example 4

[0055] Based on Example 1, the utility model provides a technical solution: preferably, a portion of the bottom surface of the leakage groove 9 close to the coating roller 16 is a horizontal plane, the side close to the water outlet 14 is an inclined surface, and the leakage hole 10 is arranged on the horizontal plane.

[0056] In this embodiment, by setting a portion of the bottom surface of the drainage groove 9 close to the coating roller 16 as a horizontal surface and a side close to the water outlet 14 as an inclined surface, the water in the water tank 11 will gather at the bottom surface of the drainage groove 9 when flowing out from the water outlet 14, so that the water can flow out better.

[0057] The working principle of the concrete curing device for building construction is described in detail below.

[0058] like Figure 1-5As shown, after the concrete is poured, it needs to be cured. Before curing, the electric rail 1 is first installed on both sides of the concrete, then the gantry 2 is installed on the slide rail 4, and then the main body 3 is fixedly connected to the movable end of the cylinder 6 on the gantry 2; during curing, a sufficient amount of water is added to the water tank 11, and the water in the water tank 11 enters the leakage groove 9 through the water outlet 14. As the movement of the gantry 2 drives the main body 3 to move, the water in the leakage groove 9 leaks out from the leakage hole 10 to moisten the concrete below the main body 3. When the water level in the leakage groove 9 is higher than the leakage hole, the water in the leakage groove 9 will pass through the floating The hole enters the float groove 12, so that the water level of the float groove 12 is consistent with the water level of the leakage groove 9. When the water level rises, the floating plate 20 rises with the rise of the water level, thereby driving the baffle 19 to rise and close the water outlet 14 to keep the water level fixed. When the water level drops, the baffle 19 is driven to drop so that the water in the water tank 11 can re-enter the leakage groove 9 to maintain the water level, thereby regulating the water volume, so that the water volume in the leakage groove 9 remains stable, and the speed of water falling from the leakage hole 10 remains stable, so that the curing of each part of the concrete is uniform, and the curing effect is improved; before curing, the coating roller 1 The film on 6 is fixed to one end of the concrete, and the film passes between the pressure roller 23 and the film roller 16. The film is tangential to the lower end of the pressure roller 23. When the gantry 2 moves, the film roller 16 rotates out of the film to cover the concrete, reducing the evaporation of water, protecting the concrete surface, and improving the curing effect. When water leaks from the leakage groove 9, if the concrete has not been completely formed, the water flow may impact the concrete surface and form small pits on the concrete surface. In some engineering projects with higher requirements, the concrete surface needs to be flat. The pressure roller 23 is used to press the concrete surface. The soil surface is pressed to make the concrete surface flat, and the coating can also be pressed to make the coating fit the concrete better; when encountering concrete of different heights, when the cylinder 6 drives the main body 3 to rise too high or too low, the angle of the support arm 22 is adjusted by turning the handle 26 to adjust the position of the pressure roller 23. When the position of the pressure roller 23 is determined, the sliding groove block 29 is moved in the direction of the groove block 29 so that the groove block 29 is inserted into the movable groove 28. Because the groove block 29 is square in shape, it cannot be rotated, thereby limiting the movable groove 28 to prevent the displacement of the pressure roller 23.

[0059] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
