Description

Technical Field

[0001] This invention relates to the field of concrete curing technology, specifically to a leveling layer concrete curing equipment and its curing method. Background Technology

[0002] Concrete curing is a crucial step in ensuring the strength and durability of concrete. Its purpose is to provide suitable temperature and humidity conditions for the concrete, promote the full hydration reaction of cement, and prevent cracking caused by factors such as dryness and drastic temperature changes. Leveling layer refers to a layer of material used to level the base surface during building construction. It is usually used for pre-construction treatment of parts such as floors, walls, or roofs. Currently, most leveling layers are made of concrete. After the leveling layer concrete is constructed, it needs to be cured to ensure the strength growth and performance stability of the concrete. The commonly used curing methods are mainly membrane curing and water spraying curing.

[0003] A search revealed a concrete footprint removal and coating machine in patent application number 201921153775.7. This machine is described as follows: when a worker pulls the machine backward, a vibrating motor operates, causing the repair panel to vibrate and eliminating footprints and other marks left on the road surface. Simultaneously, the rollers and the repair panel are on the same horizontal plane, and the rolling of the rollers further smooths the road surface, effectively reducing its roughness and removing footprints left by workers. This solves the problem that coating machines cannot effectively repair concrete surfaces and remove footprints left by workers. Additionally, a concrete spray curing device is disclosed in patent application number 202321960781.X. In this device, the spraying assembly on top of the support platform supplies liquid through the inside of the material cylinder for spray curing of the concrete material. Based on the existing technologies, different equipment is required for the mulching and spray curing of existing leveling concrete layers. Different types of equipment not only have high procurement costs, but also require a large storage space. In the limited space of the construction site, the storage and management of equipment becomes a major problem. In addition, the transportation and handling of different equipment will also cause certain damage to the roads and environment of the construction site, affecting the construction progress and on-site safety. Therefore, we propose a leveling concrete curing equipment and its curing method. Summary of the Invention

[0004] To address the aforementioned technical problems, this application provides a leveling layer concrete curing device, comprising a frame, a scraper mounted on the frame, a hollow mounting cylinder and movable wheels mounted on the frame, hollow pressure film cylinders at both ends of the hollow mounting cylinder, and multiple water outlet holes on both the hollow mounting cylinder and the hollow pressure film cylinder, and a linkage switching component between the hollow mounting cylinder and the movable wheels, wherein when the hollow mounting cylinder moves to the lower end for film covering, the linkage switching component ensures that the movable wheels are not in contact with the concrete surface, and an adjustment component is provided between the frame and the hollow pressure film cylinder.

[0005] In some embodiments, each of the two hollow film-forming cylinders has a first connecting portion at one end facing the hollow mounting cylinder, and one of the hollow film-forming cylinders has a second connecting portion installed at the end facing away from the hollow mounting cylinder. Both ends of the hollow mounting cylinder have mating portions that cooperate with the first connecting portions.

[0006] In some embodiments, a cylindrical mounting component is also included, the cylindrical mounting component including a fixed seat and a movable seat, the fixed seat being fixed to one end of the frame, the movable seat being movably disposed at the other end of the frame, the fixed seat and the movable seat having vertical grooves on their opposite sides, the hollow mounting cylinder being vertically disposed between the two grooves, and the grooves having through holes at their upper and lower ends.

[0007] In some embodiments, the mounting assembly includes a second fixing block fixed to one end of the frame near the movable seat. The second fixing block has a guide groove, and the movable seat has a guide bar that slides into the guide groove. The second fixing block also has a second positioning pin that limits the guide bar.

[0008] In some embodiments, a limiting component is further included, the limiting component including a collar sleeved on one end of the hollow mounting cylinder, the hollow mounting cylinder rotatably engaging with the collar, a second connecting block fixed on the collar, a second threaded rod rotatably connected to the second connecting block, a mounting plate fixed to the top of the fixing seat, and the second threaded rod screwed through the mounting plate.

[0009] In some embodiments, the linkage switching assembly is provided in two sets. Each set of the linkage switching assembly includes a first fixing block fixed to the inner side wall of the frame and a top bar connected to a second connecting block. The first fixing block has a vertical receiving groove. The frame is also hinged with a hinge bar. The top bar is located below one end of the hinge bar. The two ends of the moving wheel are each equipped with a first connecting block. A guide block is fixed to the upper end of the side of the first connecting block facing the first fixing block. The guide block slides into the receiving groove. A spring is connected between the lower end face of the guide block and the bottom end of the receiving groove. A connecting bar connects the two linkage switching assemblies.

[0010] In some embodiments, a protruding rod is connected to the upper end face of the top bar, and a through groove is provided on the hinge bar, through which the protruding rod passes.

[0011] In some embodiments, the adjustment assembly includes an installation strip and an arc-shaped sleeve disposed outside the hollow pressure film cylinder. The hollow pressure film cylinder is rotatably and movable along its length to the arc-shaped sleeve. A first threaded rod is screwed onto the installation strip, and a positioning structure is provided between the bottom end of the first threaded rod and the arc-shaped sleeve.

[0012] In some embodiments, the positioning structure includes a circular plate fixed to the outside of a first threaded rod and a circular seat fixed to an arc-shaped sleeve. The bottom end of the first threaded rod is rotatably connected to the circular seat. The upper end face of the circular seat is provided with a plurality of positioning holes in a ring array. A first positioning pin is provided through the circular plate, which can be inserted into any of the positioning holes.

[0013] A method for curing leveling layer concrete, using the leveling layer concrete curing equipment described above, includes the following steps: S1. During concrete membrane curing, place the hollow installation cylinder at the bottom of the groove and limit it using the limiting component. Then, use the installation component to remove the movable seat, and then remove the hollow installation cylinder. After that, put the roll of film to be used on the outside of the hollow installation cylinder, and finally install the hollow installation cylinder between the bottom ends of the two grooves. S2. Manually pull the equipment to move it on the newly poured and leveled concrete surface, use a scraper to smooth the footprints, and use the hollow installation cylinder that rotates in contact with the concrete surface to synchronously place the film, thereby achieving film curing. S3. During film curing, the deflection angle and height of the hollow film press cylinder can be adjusted using the adjustment component. The hollow film press cylinder can be used in conjunction with film covering to reduce the occurrence of film curling. S4. When performing concrete spraying and curing, position the hollow installation cylinder at the top of the groove. At this time, the moving wheel can be moved down to contact the concrete surface through the linkage switching component. Then, adjust the hollow pressure film cylinder to the same height using the adjustment component. Subsequently, move the hollow pressure film cylinder to connect the hollow pressure film cylinder and the hollow installation cylinder. Then, supply water to the outside through the second connection part at the end of the hollow pressure film cylinder. S5. The equipment is manually moved across the concrete surface for water spraying and curing.

[0014] This invention has at least the following beneficial effects: 1. By combining and separating the hollow installation cylinder and the hollow pressure film cylinder, the two functions of spray curing and film covering curing can be switched, realizing two uses of one equipment. There is no need to set up different equipment, which reduces the procurement cost and does not require a large storage space, while improving construction efficiency.

[0015] 2. The hollow installation cylinder and the hollow pressure film cylinder can be combined or separated: When combined, they form a long spray pipe, which sprays water evenly onto the concrete surface through the water outlet, suitable for the spray curing stage that requires continuous moisture. When separated, the hollow installation cylinder is fitted with a curing membrane, and the membrane covering operation is achieved by rotation; the hollow pressure film cylinder can independently assist in membrane pressing, improving the flatness and adhesion of the membrane, suitable for the membrane curing stage.

[0016] 3. When the hollow installation cylinder is moved upward by rotating the second threaded rod, the linkage switching component plays a role. Based on the lever principle, the top bar pushes the hinge bar to rotate, which drives the moving wheels to move downward and contact the ground. The equipment can then move flexibly to perform spray curing. Conversely, when the hollow installation cylinder moves downward to perform film curing, the moving wheels are raised to avoid damaging the unhardened concrete surface.

[0017] 4. The cylinder mounting components, mounting assembly, and limiting assembly work together to achieve the lifting, rotation, and stable positioning of the hollow mounting cylinder; the adjustment assembly can adjust the deflection angle and height of the hollow pressure film cylinder to adapt to the film covering needs.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please see Figures 1-12As shown, the present invention provides a technical solution: a leveling layer concrete curing device, including a frame 1, which has a U-shaped structure. A scraper 3 and a handrail 4 are installed on the frame 1. The scraper 3 can be made of wear-resistant alloy steel with a mirror-polished surface to reduce friction with the concrete surface and ensure smooth leveling operations. A rubber sleeve can be installed at the end of the handrail. This rubber sleeve has a honeycomb-shaped breathable structure with an inner layer of memory foam, which effectively absorbs hand pressure and reduces fatigue during prolonged operation. Furthermore, the surface of the rubber sleeve is also provided with anti-slip textures. Even in humid environments, the grip remains stable. A vibration motor can be installed on the scraper 3, and a lithium battery can be installed on the handrail 4. The lithium battery powers the vibration motor, and activating the control button on the handrail 4 activates the motor, causing the scraper 3 to vibrate. This can eliminate footprints and other marks left on the concrete surface during curing. The frame 1 is also equipped with a hollow installation cylinder 2 and moving wheels 6. The hollow installation cylinder 2 is open at both ends, and the moving wheels 6 consists of two moving wheels and a connecting shaft. The moving wheels are rotatably mounted on the outside of the connecting shaft, and hollow pressure cylinders 5 are provided at both ends of the hollow installation cylinder 2. The hollow installation cylinder 2 and the hollow pressure film cylinder 5 can be combined and separated. When combined, they form a relatively long spray pipe for spray curing concrete. When separated, a roll of film is fitted over the hollow installation cylinder 2, allowing for concrete curing through the rotatable cylinder. The hollow pressure film cylinder 5 can cooperate with the hollow installation cylinder 2 during curing to improve the quality of the film. Both the hollow installation cylinder 2 and the hollow pressure film cylinder 5 have multiple water outlets for water discharge during spray curing. The water outlets can have a stepped structure, with the internal diameter slightly larger than the external diameter, effectively reducing... The resistance of the water flow allows the water to spray out more smoothly. A linkage switching component 7 is provided between the hollow installation cylinder 2 and the moving wheel component 6. When the hollow installation cylinder 2 moves to the lower end for membrane curing, the linkage switching component 7 moves the moving wheel component 6 upward to a state that does not contact the concrete surface. When the hollow installation cylinder 2 moves to the upper end for spray curing, the linkage switching component 7 moves the moving wheel component 6 downward to a state that contacts the concrete surface, so that the moving wheel component 6 can be used for movement (during spray curing, the concrete generally has a certain hardness, so the moving wheel component 6 can be used to move on it).

[0022] Among them, see Figure 5 as well as Figures 7-8As shown, in order to achieve the combination and separation between the hollow installation cylinder 2 and the hollow pressure film cylinder 5, a first connecting part 51 is provided at the end of each of the two hollow pressure film cylinders 5 facing the hollow installation cylinder 2, and a second connecting part 52 is installed at the end of one of the hollow pressure film cylinders 5 away from the hollow installation cylinder 2. Both ends of the hollow installation cylinder 2 are provided with mating parts that cooperate with the first connecting part 51. The first connecting part 51 and the second connecting part 52 are preferably threaded cylinders (hollow inside and threaded on the outer wall), and the mating part is also a threaded cylinder (hollow inside and threaded on the inner wall), so as to achieve the detachable connection between the first connecting part 51 and the mating part, so as to achieve the detachable connection between the second connecting part 52 and the external water supply hose.

[0023] Specifically, through the detachable design of the threaded connection, the hollow installation cylinder 2 and the hollow pressure film cylinder 5 can be combined or separated: When combined, they form a long spray pipe, which sprays water evenly onto the concrete surface through the water outlet, suitable for spray curing stages that require continuous moisture (such as after the initial setting and mid-term curing of concrete); When separated, the hollow installation cylinder 5 is fitted with a curing membrane, and the membrane covering operation is achieved by rotation; the hollow pressure film cylinder 5 can independently assist in membrane pressing, improving the flatness and adhesion of the membrane, suitable for the membrane curing stage (such as after concrete pouring and leveling).

[0024] Advantages: No need to replace the entire equipment structure; it can be adapted to different maintenance process requirements simply by disassembling and assembling parts, reducing equipment downtime and improving construction efficiency. Example 2: See Figures 3-5 as well as Figure 9 As shown, the leveling layer concrete curing equipment also includes a cylinder mounting component 9, which includes a fixed seat 91 and a movable seat 92. The fixed seat 91 is fixed to one end of the frame 1, and the movable seat 92 is movably located at the other end of the frame 1. Specifically, it can move along a direction that can approach or move away from the fixed seat 91. The fixed seat 91 and the movable seat 92 are parallel to each other, and each of the opposite sides of the fixed seat 91 and the movable seat 92 has a vertical groove 13. The hollow mounting cylinder 2 is vertically and vertically located between the two grooves 13. The upper and lower ends of the grooves 13 have through holes 12. When the hollow mounting cylinder 2 is located between the two grooves 13, it can be prevented from moving out by the obstruction of the fixed seat 91 and the movable seat 92. The hollow mounting cylinder 2 is rotatably located between the two grooves 13.

[0025] See Figure 5 as well as Figure 7As shown, it also includes an installation component 11, which includes a second fixing block 111 fixed to one end of the frame 1 near the movable seat 92. The second fixing block 111 has a guide groove 114, which is preferably smaller on the outside and larger on the inside. The movable seat 92 is fixed with a guide bar 113 that slides with the guide groove 114. The design of the guide groove 114 can effectively prevent the guide bar 113 from coming off during sliding, and at the same time provide a large contact area for both, ensuring uniform load distribution. The second fixing block 111 is also provided with a second positioning pin 112 that limits the guide bar 113. The second positioning pin 112 is preferably a limiting screw, which is screwed into the second fixing block 111 to press the guide bar 113 to ensure the stability of the movable seat 92.

[0026] Example 3: See Figure 5 As shown, the leveling layer concrete curing equipment also includes a limiting component 10. The limiting component 10 includes a collar 101 sleeved on one end of the hollow mounting cylinder 2. The hollow mounting cylinder 2 rotatably engages with the collar 101. Specifically, a protruding ring can be fixed at the end of the outer wall of the hollow mounting cylinder 2, and an annular groove is formed on the inner wall of the collar 101 to allow the protruding ring to slide into the annular groove. A second connecting block 102 is fixed on the collar 101, and a second threaded rod 103 is rotatably connected to the second connecting block 102. A handwheel is installed at the top of the rod 103, and a mounting plate 911 is fixed at the top of the fixed base 91. The second threaded rod 103 is screwed through the mounting plate 911. When it is necessary to move the hollow mounting cylinder 2 from the bottom to the top, the operator can hold the hollow mounting cylinder 2 with one hand and lift it up, while turning the handwheel with the other hand to move the second threaded rod 103 up until it reaches the highest point (when the hollow mounting cylinder 2 reaches the top by screwing the second threaded rod 103, the end of the hollow mounting cylinder 2 is directly opposite the through hole 12 at the top).

[0027] See Figures 9-12As shown, the linkage switching assembly 7 has two sets. Each set of linkage switching assemblies 7 includes a first fixing block 71 fixed to the inner wall of the frame 1 and a top bar 72 connected to the second connecting block 102. The first fixing block 71 has a vertical receiving groove 711. The frame 1 is also hinged with a hinge bar 74. The top bar 72 is located below one end of the hinge bar 74. The two ends of the moving wheel 6 are each equipped with a first connecting block 75. A guide block 76 is fixed to the upper end of the side of the first connecting block 75 facing the first fixing block 71. The guide block 76 slides into the receiving groove 711, and a spring 77 is connected between the lower end of the guide block 76 and the bottom end of the receiving groove 711. A connecting bar 73 is connected between the two linkage switching assemblies 7. The connecting bar 73 is made of solid steel bar and has high strength. In a rigid manner, specifically, the connecting strip 73 is connected between the top strips 72 of the two sets of linkage switching components 7 to achieve synchronous movement of the top strips 72 at both ends. Specifically, it ensures that the top strips 72 at both ends move up or down synchronously, avoiding structural jamming or tilting caused by uneven force on one side. When the second threaded rod 103 is rotated to move the hollow installation cylinder 2 upward, the second connecting block 102 drives the top strip 72 upward. Based on the lever principle, the top strip 72 pushes the hinge strip 74 to rotate around its hinge point. The other end of the hinge strip 74 presses down on the first connecting block 75 to move the moving wheel 6 downward until the moving wheel of the moving wheel 6 contacts the ground. The moving wheel 6 can then be used for subsequent movement. At the same time, the hollow installation cylinder 2 gradually detaches from the ground, creating space for subsequent spraying maintenance operations.

[0028] In summary, through linkage switching, when the moving wheel 6 touches the ground, the hollow mounting cylinder 2 is lifted off the ground, facilitating the overall movement of the equipment for use during concrete spraying and curing; conversely, when the hollow mounting cylinder 2 touches the ground, the moving wheel 6 is lifted for use during concrete film curing (the concrete film curing process requires that a film be covered immediately after pouring to form a closed and moisturizing environment and accelerate the hydration reaction process. However, before the initial setting of the concrete, it is in a fluid state and its surface structure has not yet formed strength. If the moving wheel 6 is used to move the film curing equipment at this time, the wheel will generate local stress concentration at the moment of contact with the concrete surface. This stress will cause large-area depressions, indentations and other defects on the concrete surface. In severe cases, it may even disturb the aggregate distribution and destroy the uniformity of the internal structure. It is difficult to achieve smoothing by simply using the scraper 3).

[0029] Preferably, the guide block 76 is a T-shaped structure or other structure with a smaller outer side and a larger inner side, so that the guide block 76 can only move vertically along the receiving groove 711, preventing the guide block 76 from leaving the receiving groove 711, and ball bearings can be set in the receiving groove 711 to reduce friction. In addition, when the moving wheel 6 moves down, the second threaded rod 103 is used to press and limit it, and at this time the spring 77 is in a compressed state. When the second threaded rod 103 is rotated in the opposite direction to move the hollow mounting cylinder 2 down, the elastic force of the spring 77 can be used to quickly restore it.

[0030] Furthermore, a protruding rod 721 is connected to the upper end face of the top bar 72, and a through groove 741 is opened on the hinge bar 74. The protruding rod 721 passes through the through groove 741, and the two form a sliding hinge pair. This structural design not only ensures a reliable connection between the top bar 72 and the hinge bar 74, but also realizes stable force transmission, providing a guarantee for the stable operation of the entire linkage switching assembly 7.

[0031] Example 4: See Figures 2-8 As shown, an adjustment assembly 8 is provided between the frame 1 and the hollow film pressing cylinder 5. The adjustment assembly 8 is used to adjust the deflection angle of the hollow film pressing cylinder 5 so that during the film covering and curing operation of the hollow installation cylinder 2, the hollow film pressing cylinder 5 can be used to synchronously roll the two sides of the film to reduce the occurrence of film curling. The adjustment assembly 8 includes an installation strip 81 and an arc-shaped sleeve 82 provided on the outside of the hollow film pressing cylinder 5. The arc-shaped sleeve 82 has a semi-circular structure to ensure that part of the hollow film pressing cylinder 5 is not obstructed, so that the film can be used during the film covering and curing operation. When the hollow film pressing cylinder 5 is used for film covering, the arc-shaped sleeve 82 is used to prevent it from scratching the film. The hollow film pressing cylinder 5 is rotatably and movable along its length to the arc-shaped sleeve 82. That is, the hollow film pressing cylinder 5 can rotate freely and move axially within the arc-shaped sleeve 82. A first threaded rod 84 is screwed onto the mounting strip 81. A positioning structure 83 is provided between the bottom end of the first threaded rod 84 and the arc-shaped sleeve 82. Rotating the first threaded rod 84 can realize the lifting and lowering of the hollow film pressing cylinder 5 so as to adjust its height as needed.

[0032] See Figure 7 and Figure 8 As shown, the positioning structure 83 includes a circular plate 831 fixed to the outside of the first threaded rod 84 and a circular seat 832 fixed to the arc sleeve 82. The bottom end of the first threaded rod 84 is rotatably connected to the circular seat 832. The upper end face of the circular seat 832 is provided with a plurality of positioning holes 833 in a ring array. A first positioning pin 834 that can be inserted into any positioning hole 833 is provided through the circular plate 831. When it is necessary to deflect the hollow film cylinder 5, the first positioning pin 834 can be removed first, and then the hollow film cylinder 5 can be rotated directly. After adjusting the deflection angle, the first positioning pin 834 is installed and the bottom end of the first positioning pin 834 is inserted into the corresponding positioning hole 833, which can lock the adjusted hollow film cylinder 5.

[0033] A method for curing leveling layer concrete, using the aforementioned leveling layer concrete curing equipment, includes the following steps: S1. During concrete covering and curing, the hollow installation cylinder 2 is positioned at the bottom of the groove 13 and limited by the limiting component 10. Then, the movable seat 92 is removed by the installation component 11, and the hollow installation cylinder 2 is removed. Then, the roll film to be used is put on the outside of the hollow installation cylinder 2, and finally, the hollow installation cylinder 2 is installed between the bottom ends of the two grooves 13. S2. Manually pull the equipment to move it on the newly poured and leveled concrete surface, use the scraper 3 to smooth the footprints, and use the hollow installation cylinder 2 that rotates in contact with the concrete surface to synchronously place the film, thereby achieving film curing. S3. During film curing, the deflection angle and height of the hollow film pressing cylinder 5 can be adjusted using the adjustment component 8. The hollow film pressing cylinder 5 is used in conjunction with film covering to reduce the occurrence of film curling. S4. During concrete spraying and curing, the hollow installation cylinder 2 is positioned at the upper end of the groove 13. At this time, the moving wheel 6 can be moved down to contact the concrete surface through the linkage switching component 7. Then, the hollow pressure film cylinder 5 is adjusted to the same height using the adjustment component 8. Subsequently, the hollow pressure film cylinder 5 is moved to connect with the hollow installation cylinder 2. After that, the external water supply hose is supplied from the second connection part 52 at the end of the hollow pressure film cylinder 5. S5. The equipment is manually moved across the concrete surface for water spraying and curing.
