Description

Technical Field

[0001] This invention relates to the field of concrete curing technology, and in particular to a concrete curing device for construction. Background Technology

[0002] In road construction, the development of concrete strength depends on its hydration status. Temperature and humidity are crucial factors affecting the rate and extent of cement hydration. If the weather is hot and the air is dry after concrete pouring, and curing is not carried out promptly, the water in the concrete will evaporate too quickly, leading to dehydration. This prevents the cement particles, which have already formed a gel, from fully hydrating and transforming into stable crystals, resulting in insufficient bonding strength and causing flaking or powdering on the concrete surface. Furthermore, premature evaporation of water before the concrete has reached sufficient strength can cause significant shrinkage deformation and drying shrinkage cracks. Therefore, curing in the initial stage after concrete pouring is extremely important; humidification curing should begin immediately after the concrete has set.

[0003] For example, Chinese Patent Publication No. CN217000980U discloses a concrete curing device for building construction, including a shell. First through holes are provided on both sides of the top of the shell. A first vertical rod is installed inside the cavity of the first through hole. A horizontal plate is fixedly connected to the top of the first vertical rod, and a water tank is fixedly connected to the right side of the top of the horizontal plate. This invention, through the cooperation of the shell, first vertical rod, horizontal plate, water tank, control box, delivery pump, support rod, spray plate, first electric telescopic rod, connecting rod, moving plate, spring, damper, second through hole, second vertical rod, fixed plate, pulley, second electric telescopic rod, and transmission rod, has strong stability, improves the practicality of the concrete curing device for building construction, and solves the problem of poor performance of previous concrete curing devices for building construction.

[0004] For example, Chinese Patent Publication No. CN114606844A discloses a concrete curing vehicle, including a movable support mechanism and a lifting and adjusting mechanism. The lifting and adjusting mechanism includes a lifting frame for lifting the support, a lifting transmission assembly for driving the lifting frame up and down, a self-locking adjusting assembly for adjusting the transmission of the lifting transmission assembly, and a lifting guide assembly for guiding the lifting frame up and down. It also includes a follow-up directional water spraying mechanism, which includes a follow-up reversing water spraying assembly for reversing water spraying direction and a moving transmission assembly for driving the follow-up reversing water spraying assembly to move. The concrete curing vehicle provided by this invention, with its lifting and adjusting mechanism and follow-up directional water spraying mechanism, can change the direction of water spraying as the vehicle moves to perform water spraying and curing on concrete pavements, thereby reducing the number of times workers need to pause water spraying, shortening the water spraying and curing time, and reducing the labor intensity of workers.

[0005] The concrete curing devices mentioned above all use a water spraying structure to directly spray water onto the concrete for automatic curing. Although this eliminates the need for manual watering, direct water spraying can easily cause some impact on the concrete surface, which can damage the surface structure of the concrete. At the same time, the water spraying area is not large enough, which affects the overall efficiency and effect of curing.

[0006] Therefore, it is necessary to provide a concrete curing device for construction to solve the above-mentioned technical problems. Summary of the Invention

[0007] The purpose of this invention is to provide a concrete curing device for construction, in order to solve the problems in the above-mentioned background technology that direct water spraying can easily impact the concrete surface, damage the surface structure of the concrete, and the water spraying area is not large enough, thus affecting the overall curing efficiency and effect.

[0008] To achieve the above objectives, the present invention provides the following solution to the above technical problems: a concrete curing device for construction, comprising a support plate, a water pipe arranged along the width direction of the support plate on one side above the support plate, a plurality of water outlets opened at the bottom of the water pipe, and a jetting component for buffering and spraying the water sprayed from the water outlets directly below the water pipe.

[0009] As a further embodiment of the present invention, the jetting assembly includes a rotatable shaft arranged along the length of the water pipe, the shaft being positioned directly below the water outlet, and a plurality of connecting rods fixed on the side of the shaft. A blade plate is fixed to the end of the connecting rod away from the shaft, and the rotating blade plate buffers and jets the water jetting from the water outlet.

[0010] As a further embodiment of the present invention, the side of the blade plate that comes into contact with water is configured as an arc surface.

[0011] As a further embodiment of the present invention, an inner sleeve is provided on the outside of the shaft, which is coaxially arranged with the shaft. The two ends of the inner sleeve are closed and the two ends of the shaft are rotatably connected to the two end side walls of the inner sleeve. A gap is provided between the end of the blade plate away from the connecting rod and the inner side wall of the inner sleeve. Multiple first flow ports are provided on the columnar side of the inner sleeve to allow the sprayed water flow to pass through.

[0012] As a further embodiment of the present invention, the outer side of the inner sleeve is provided with a flow regulating component for adjusting the flow area of ​​the first flow port. The flow regulating component includes an outer sleeve that is slidably fitted onto the outer side wall of the inner sleeve, and the outer sleeve has a plurality of second flow ports corresponding to the first flow port on its cylindrical side surface.

[0013] As a further embodiment of the present invention, a flow-slowing component is provided between the water pipe and the inner sleeve to further buffer the water flow ejected from the outlet. The flow-slowing component includes a connecting cover disposed between the water pipe and the inner sleeve and arranged along the length of the water pipe. The top and bottom ends of the connecting cover are fixed to the outer wall of the bottom end of the water pipe and the top end of the inner sleeve, respectively. The inner sleeve and the outlet are connected through the connecting cover. A first guide plate is fixed on the inner side wall of the connecting cover and arranged along the length of the connecting cover. The first guide plate is inclined and a gap is provided between the lower end of the first guide plate and the side wall of the connecting cover.

[0014] As a further embodiment of the present invention, a second guide plate located below the first guide plate is fixed on the inner wall of the connecting cover. The second guide plate is arranged at an angle and a gap is provided between the lower end of the second guide plate and the inner wall of the connecting cover. The lower ends of the second guide plate and the first guide plate are offset to each other from left to right.

[0015] As a further embodiment of the present invention, the top opening of the connecting cover is larger than the bottom opening.

[0016] As a further embodiment of the present invention, an L-shaped base plate is fixed on the outer side wall of the connecting cover, and a protruding plate that slides inside the L-shaped base plate is fixed at the top of the outer sleeve. A locking bolt is threaded onto the L-shaped base plate, and the screw end of the locking bolt contacts the side of the protruding plate.

[0017] As a further embodiment of the present invention, a rubber pad is fixedly attached to the end face of the locking bolt, and the plurality of water outlets are distributed at equal intervals.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The water flow is intercepted, buffered, and dispersed by the jetting component, so that the dispersed water flow falls onto the concrete road surface in a parabolic trajectory. This buffers and disperses the water flow, increases the water spraying area, and humidifies the concrete road surface. It avoids the impact of direct water spraying on the concrete, which can cause some damage to the surface structure of the concrete. While increasing the water spraying area, it also protects the surface structure of the concrete road, effectively reducing the amount of subsequent concrete road repair work.

[0020] 2. The water jet from the outlet flows into the jet assembly through the flow buffer component. As the water flows through the flow buffer component, the impact force of the water jet is further buffered, reducing the impact force of the water jet and further improving the "impact reduction" effect of the water jet. This improves the protection of the concrete surface while the water jet wets it.

[0021] 3. The amount of water sprayed after passing through the jetting component can be adjusted by the flow regulating component. This allows for adaptive adjustment based on the different stages or watering requirements of the concrete road surface, and the watering volume can be adjusted according to different application scenarios, effectively increasing the applicability of the device and improving its overall practicality.

Detailed Implementation

[0035] The present invention will be further described below with reference to embodiments.

[0036] Please see Figure 1-10This invention provides a concrete curing device for construction, including a support plate 7, a support rod 6 fixed on the top surface of the support plate 7, a water pipe 4 fixed at the top of the support rod 6 located on one side above the support plate 7 and arranged along the width direction of the support plate 7, a plurality of water outlets 14 opened at the bottom of the water pipe 4, a jetting component 1 for buffering and spraying the water sprayed from the water outlets 14 is arranged directly below the water pipe 4, a water pump 9 and a water tank 10 are fixed on the top surface of the support plate 7, the input end of the water pump 9 is connected to the inside of the water tank 10, and the output end of the water pump 9 is connected to a water supply device. Pipe 5, the end of the water supply pipe 5 away from the water pump 9 is sealed and connected to the inside of the water pipe 4. Multiple symmetrically distributed support rods 13 are fixed on the bottom surface of the support plate 7. Self-locking casters 8 are installed at the bottom ends of the support rods 13. A flow-slowing component 2 is provided between the water pipe 4 and the jetting component 1 to further buffer the water flow sprayed from the outlet 14. A flow-regulating component 3 is provided on the outside of the jetting component 1 to adjust the size of the jetting water flow. The water flow sprayed from the outlet 14 enters the jetting component 1, and the jetting component 1 disperses and refines the water flow, making the dispersed water flow more fine and fine. The water is sprayed onto the concrete road surface in a parabolic trajectory, buffering the flow and increasing the spray area. This moisturizes the concrete surface and avoids the impact of direct water spraying, which could damage the concrete surface structure. While increasing the spray area, it also protects the concrete surface, effectively reducing the workload of subsequent repairs. The water sprayed from outlet 14 flows through flow buffer 2 into the spraying component 1. As the water passes through flow buffer 2, the impact force is further buffered, reducing the impact and improving the "impact reduction" effect. This enhances the protection of the concrete surface while wetting it. The amount of water sprayed after passing through the spraying component 1 can be adjusted by flow regulating component 3. This allows for adaptive adjustments based on different stages or water volume requirements of the concrete road surface, increasing the applicability and overall practicality of the device.

[0037] Further as Figure 1 , Figure 4 , Figure 7 and Figure 8As shown, it is worth noting that the water jet assembly 1 includes a shaft 101 located directly below the water outlet 14 and arranged along the length of the water pipe 4. Multiple connecting rods 103 are fixed on the side of the shaft 101 at equal intervals. A blade plate 102 is fixed to the end of the connecting rod 103 away from the shaft 101. The rotating blade plate 102 buffers and jets the water jet from the water outlet 14. The water jet from the water outlet 14 flows into the blade plate 102. The rotating shaft 101 drives the multiple blade plates 102 to rotate synchronously through the multiple connecting rods 103. Thus, the multiple blade plates 102 disperse and refine the water jet, causing the dispersed water jet to fall onto the concrete road surface in a parabolic trajectory. This buffers and jets the water jet, increases the water spray area, and humidifies the concrete road surface, avoiding the impact of direct water spraying on the concrete, which could cause some damage to the surface structure of the concrete.

[0038] Further as Figure 4 and Figure 8 As shown, it is worth noting that an inner sleeve 104 is provided on the outside of the shaft 101, coaxially arranged with the shaft 101. The two ends of the inner sleeve 104 are closed, and the two ends of the shaft 101 are rotatably connected to the two end side walls of the inner sleeve 104. A motor 106 with its output end coaxially fixed to one end of the shaft 101 is fixed on the outer side wall of one end of the inner sleeve 104. A gap is provided between the end of the blade plate 102 away from the connecting rod 103 and the inner side wall of the inner sleeve 104. A spraying water flow is allowed on the cylindrical side of the inner sleeve 104. The water flows through multiple first flow ports 105, which are equidistantly distributed. The motor 106 drives the shaft 101 to rotate, causing the blade plate 102 to intercept, buffer, and disperse the water flow. The water flow dispersed and thrown out by the blade plate 102 impacts the inner wall of the inner casing 104. The water flow is evenly sprayed out through the multiple equidistant first flow ports 105, thereby further refining the water flow, improving the uniformity of water spraying, and thus improving the humidification effect on the concrete road.

[0039] Further as Figure 2 , Figure 3 , Figure 4 and Figure 9As shown, it is worth noting that the flow regulating component 3 includes an outer casing 301 that is slidably fitted onto the outer wall of the inner casing 104. A second flow port 302 is provided on the column side of the outer casing 301. Multiple second flow ports 302 are provided, and multiple second flow ports 302 are correspondingly provided with multiple first flow ports 105. By adjusting the position of the outer casing 301, the second flow ports 302 and the first flow ports 105 are misaligned to different degrees, thereby adjusting the flow area of ​​the first flow ports 105 to adjust the amount of water sprayed through the first flow ports 105. This allows for adaptive adjustment according to the different stages or different watering requirements of the concrete road surface, and the watering volume can be adjusted according to different application scenarios, effectively increasing the applicability of the device and improving its overall practicality.

[0040] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the slow-flow component 2 includes a connecting cover 201 whose top and bottom ends are respectively fixed to the outer wall of the bottom end of the water pipe 4 and the top end of the inner sleeve 104. The connecting cover 201 is arranged along the length of the water pipe 4. A first guide plate 202 is fixed on the inner side wall of the connecting cover 201. The first guide plate 202 is arranged along the length of the connecting cover 201 and is inclined. A gap is provided between the lower end of the first guide plate 202 and the side wall of the connecting cover 201. The inner sleeve 104 and the outlet 14 are connected through the connecting cover 201. A second guide plate 203 is fixed on the inner side wall of the connecting cover 201. The second guide plate 203 is located below the first guide plate 202. The second guide plate 203 is arranged at an angle, with a gap between its lower end and the inner wall of the connecting cover 201. The lower ends of the second guide plate 203 and the first guide plate 202 are staggered to the left and right. The water flow sprayed from the outlet 14 flows into the inner sleeve 104 through the connecting cover 201. When the water flows through the connecting cover 201, it flows down in a Z-shape from the gap between the first guide plate 202 and the second guide plate 203 and the inner wall of the connecting cover 201. The first guide plate 202 and the second guide plate 203 further buffer the impact of the water flow, reduce the impact of the water flow, and further improve the effect of "reducing the impact" of the water flow. This improves the protection of the concrete surface when the water is sprayed and wets it.

[0041] Further as Figure 5 and Figure 9As shown, it is worth noting that an L-shaped seat plate 304 is fixed in the middle of the outer wall of the connecting cover 201, and a protruding plate 303 is fixed at the top of the outer sleeve 301. The two sides of the protruding plate 303 slide against the outer side of the connecting cover 201 and the inner side of the L-shaped seat plate 304, respectively. A locking bolt 305 is threaded onto the side wall of the L-shaped seat plate 304 parallel to the protruding plate 303. The screw end of the locking bolt 305 contacts the side of the protruding plate 303. When it is necessary to adjust the spray water size, the relative fixation between the protruding plate 303 and the L-shaped seat plate 304 is released by loosening the locking bolt 305, thereby adjusting the position of the outer sleeve 301 and adjusting the flow area of ​​the first flow port 105. Then, the position of the outer sleeve 301 is fixed by tightening the locking bolt 305, thus completing the adjustment.

[0042] This solution has the following working process: When it is necessary to maintain the concrete road that has just been completed, the support plate 7 is moved along the side of the concrete road by multiple self-locking casters 8, so that the water pipe 4 is located directly above the concrete road. The support plate 7 drives the water pipe 4 located above the concrete road to move through the support rod 6. The water pump 9 delivers water with a certain water pressure from the water tank 10 to the inside of the water pipe 4 through the water supply pipe 5, and then sprays it from the bottom of the water pipe 4 through multiple water outlets 14. The water sprayed from the water outlets 14 flows into the blade plate 102. The motor 106 drives the shaft 101 to rotate, so that the water flow is intercepted, buffered and dispersed by multiple blade plates 102. The water flow dispersed and thrown by the blade plates 102 hits the inner wall of the inner casing 104. The water flow is evenly sprayed out through multiple first flow outlets 105 that are evenly distributed, so that the dispersed water flow falls onto the surface of the concrete road in a parabolic trajectory. When the spray volume needs to be adjusted, the locking bolt 305 is loosened to release the relative fixation between the convex plate 303 and the L-shaped seat plate 304, thereby adjusting the position of the outer sleeve 301. This causes the second flow port 302 and the first flow port 105 to be misaligned to different degrees, adjusting the flow area of ​​the first flow port 105 to regulate the amount of water sprayed through it. The locking bolt 305 is then tightened to fix the position of the outer sleeve 301, completing the adjustment. The water flow sprayed from the outlet 14 flows into the inner sleeve 104 through the connecting cover 201. As the water flows through the connecting cover 201, it flows down in a Z-shape from the gaps between the first guide plate 202, the second guide plate 203, and the inner wall of the connecting cover 201. The first guide plate 202 and the second guide plate 203 further buffer the impact force of the water flow, reducing its impact.

[0043] Further as Figure 7As shown, it is worth noting that the side of the blade plate 102 that comes into contact with water is set as an arc surface; in actual operation, the arc surface allows the blade plate 102 to have a larger contact area with the water flow, thereby improving the effect of the blade plate 102 in dispersing and refining the water flow.

[0044] Further as Figure 4 As shown, it is worth noting that the top opening of the connecting cover 201 is larger than the bottom opening. In actual operation, by setting the bottom opening of the connecting cover 201 to a smaller opening, the water flow is gathered and flows into the blade plate 102, which makes it easier for the blade plate 102 to better disperse and throw out the water flow.

[0045] Further as Figure 10 As shown, it is worth noting that the end face of the locking bolt 305 is fitted with a rubber pad, and the multiple water outlets 14 are evenly distributed; the rubber pad effectively improves the stability of the locking bolt 305 in locking the convex plate 303.

[0046] Further as Figure 1 As shown, it is worth noting that two inclined rods 11 are fixed at the end of the support plate 7 away from the bracket rod 6. The two inclined rods 11 are symmetrically distributed and the top of the two inclined rods 11 are fixed together with a push handle 12. The surface of the push handle 12 is fitted with a rubber sleeve.

[0047] In summary: The water jet component 1 disperses and refines the water flow, causing it to fall onto the concrete road surface in a parabolic trajectory. This buffers and disperses the water, increasing the spray area and humidifying the concrete surface. It avoids the impact of direct water spraying, which could damage the concrete's surface structure. While increasing the spray area, it also protects the concrete surface, effectively reducing the workload of subsequent repairs. The water jet from outlet 14 flows into the jet component 1 through the flow buffer component 2, further enhancing its performance. Inside component 2, the impact force of the water flow is further buffered by the flow-slowing component 2, reducing the impact force of the water flow and further improving the "impact-reducing" effect of the water flow. This improves the protection of the concrete surface while the water is being sprayed. The amount of water sprayed after passing through the throwing component 1 can be adjusted by the flow-adjusting component 3. This allows for adaptive adjustment according to different stages or different watering requirements of the concrete road surface. The amount of water sprayed can be adjusted according to different application scenarios, effectively increasing the applicability of the device and improving its overall practicality.

[0048] The motor 106 can be purchased from the market. The motor 106 is equipped with a power supply. This is a mature technology in the field and has been fully disclosed. Therefore, it will not be described again in the specification.
