Abstract
Description
Technical Field
[0001] This utility model belongs to the field of road construction technology, specifically a leveling device for concrete floor paving. Background Technology
[0002] In the construction of concrete floors in industrial plants, logistics warehousing centers, and municipal squares, the flatness of the floor directly determines the accuracy of subsequent equipment installation (such as automated production lines and warehouse racking), vehicle traffic safety (such as smooth driving of forklifts and trucks), and floor durability (reducing cracks caused by uneven stress). According to the "Code for Acceptance of Construction Quality of Concrete Structures" (GB50204), the flatness error of ultra-flat floors (such as electronics factories) must be controlled within ±2mm / 3m, and that of ordinary industrial floors must be ≤±5mm / 3m. As the "baseline core" of the leveling device, the measurement accuracy and coverage of the laser measuring instrument directly determine the final construction quality.
[0003] Narrow adjustment range: The height adjustment range of existing equipment is mostly 30-80cm, which can only be adapted to a single thickness of ground (such as a conventional 10cm thick ground). When the construction ground thickness is 5cm (residential ground) or 15cm (heavy equipment foundation), the entire set of brackets needs to be replaced or the base needs to be raised / cut. The replacement process takes 20-30 minutes per time, and multiple disassembly and assembly can easily lead to deviation in the verticality of the bracket, introducing a reference error of ±1-2mm. At the same time, the length of the bracket cannot be adjusted. Once the bracket is fixed, it is not easy to increase or decrease the detection area, resulting in frequent disassembly and assembly, which affects practicality.
[0004] Therefore, this utility model provides a leveling device for concrete floor paving. Utility Model Content
[0005] To overcome the shortcomings of the existing technology and solve at least one of the problems mentioned in the background technology, a leveling device for concrete floor paving is proposed.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A leveling device for concrete floor paving, comprising support legs; two sets of support legs are provided, and a horizontal plate is slidably connected to the inner wall of each set of support legs. U-shaped frames are fixedly installed on both sides of the horizontal plates, with the inner wall of the U-shaped frames located on the surface of the support legs. The U-shaped frames are slidably connected to the support legs. A fixing mechanism is provided on the side of the support leg closest to the U-shaped frame, and a leveling mechanism is provided at the bottom of the horizontal plate. A limiting component is provided on the side of the two sets of horizontal plates that are close to each other, and a connecting mechanism is provided on the inner wall of the limiting component. An adjusting mechanism is provided on the side of the horizontal plate close to the connecting mechanism. The fixing mechanism includes a groove, a screw, a knob, and a top plate. The groove is located on the side of the support leg away from the horizontal plate. The screw is threaded onto the inner wall of the U-shaped frame on the side away from the horizontal plate. One end of the screw is fixedly installed with the knob, and the end of the screw near the support leg is rotatably installed with the top plate. The top plate is located within the groove. The groove allows the top plate to move stably up and down on the inner wall of the support leg, preventing it from shifting. The combined use of the screw, knob, and top plate allows the user to rotate the top plate to press it firmly against the support leg, thus achieving suspension at any height on the support leg surface. It also allows the support leg to extend and retract according to uneven ground, achieving stability.
[0007] Preferably, the leveling mechanism includes a reinforcing rib, a first shaft frame, and a laser leveling device. The reinforcing rib is fixedly installed at the bottom of the horizontal plate, and its two sides are rotatably connected to the first shaft frame. The bottom of the first shaft frame is fixedly installed with the laser leveling device. In this design, the reinforcing rib can strengthen the structure of the horizontal plate, enabling it to maintain sufficient strength. The combined use of the first shaft frame and the laser leveling device can level the ground using a laser, and the measurement range can be adjusted according to the height of the horizontal plate.
[0008] Preferably, the limiting component includes a through hole and a limiting block. The through hole is opened on one side of the two sets of horizontal plate surfaces that are close to each other. Two sets of limiting blocks are provided, and the two sets of limiting blocks are fixedly installed on both sides of the inner wall of the horizontal plate. In this solution, the through hole can provide stable limiting for the second round rod, so that it will not shake violently or get stuck during adjustment. The limiting block can limit the range of motion of the second round rod, so that it can slide within a specified range.
[0009] Preferably, the connecting mechanism includes a second shaft frame, a telescopic rod, and a first round rod. Two sets of the second shaft frames are provided, and the two sets of second shaft frames are movably connected to both sides of the horizontal plate. The inner wall of the second shaft frame is fixedly installed with the first round rod, which is located in the through hole. The side of the second shaft frame away from the horizontal plate is fixedly installed with the telescopic rod. In this scheme, the cooperation of the second shaft frame, the telescopic rod, and the first round rod can connect the two sets of horizontal plates to each other and keep the two sets of horizontal plates in a consistent horizontal and vertical position, thereby enabling the two sets of laser leveling devices to measure more accurately and efficiently.
[0010] Preferably, the adjustment mechanism includes a third shaft bracket, a second round rod, and a connecting rod. The third shaft bracket is movably connected to one side of the horizontal plate. The inner wall of the third shaft bracket is fixedly installed with the second round rod, which is located inside the through hole. The second round rod is located on the side where the two sets of limiting blocks are close to each other. The side of the third shaft bracket away from the horizontal plate is fixedly installed with the connecting rod. In this scheme, the cooperation of the third shaft bracket, the second round rod, and the connecting rod can achieve the verticality or tilting of the connecting rod by sliding it inside the through hole. When the connecting rod is vertical, it will push the two sets of horizontal plates open to both sides, thereby increasing the distance between the horizontal plates and realizing the adjustment of the detection area of the laser leveling device.
[0011] Preferably, the support leg is made of stainless steel. The surface of stainless steel is relatively smooth and highly corrosion-resistant, which prevents the support leg from rusting or corroding during long-term use. At the same time, it also allows the U-shaped frame to slide smoothly on the surface of the support leg for easy replacement, thereby saving manpower.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. The concrete floor leveling device described in this utility model, through the arrangement of grooves, screws, knobs, top plates, reinforcing ribs, a first shaft frame, and a laser leveling device, allows the top plate to move stably up and down on the inner wall of the support leg, preventing it from shifting. The combined use of the screws, knobs, and top plates allows the user to rotate them to push the top plate against the support leg, thus achieving suspension at any height on the support leg surface. Simultaneously, it allows the support leg to be adjusted for uneven ground to achieve stability. The reinforcing ribs strengthen the structure of the horizontal plate, ensuring sufficient strength. The combined use of the first shaft frame and the laser leveling device allows for laser leveling of the ground, and the measurement range can be adjusted according to the height of the horizontal plate.
[0014] 2. The leveling device for concrete floor paving described in this utility model, through the setting of through holes, limiting blocks, second shafts, telescopic rods, and first round rods, enables the through holes to provide stable limiting for the second round rods, preventing violent shaking and jamming during adjustment. The limiting blocks restrict the range of motion of the second round rods, allowing them to slide within a specified range. The combined use of the second shafts, telescopic rods, and first round rods connects the two sets of horizontal plates and keeps them consistently horizontal and vertical, thereby enabling the two sets of laser leveling devices to measure more accurately and efficiently.

[0025] like Figures 1 to 5 As shown in the embodiment of this utility model, a leveling device for concrete floor paving includes support legs 1; two sets of support legs 1 are provided, and a horizontal plate 2 is slidably connected to the inner wall of the two sets of support legs 1. U-shaped frames 3 are fixedly installed on both sides of the horizontal plate 2, and the inner wall of the U-shaped frames 3 is located on the surface of the support legs 1. The U-shaped frames 3 are slidably connected to the support legs 1. A fixing mechanism 4 is provided on the side of the support leg 1 near the U-shaped frame 3, and a leveling mechanism 5 is provided at the bottom of the horizontal plate 2; a limiting component 6 is provided on the side of the two sets of horizontal plates 2 that are close to each other, and a connecting mechanism 7 is provided on the inner wall of the limiting component 6; An adjustment mechanism 8 is provided on the side of plate 2 near the connecting mechanism 7; the fixing mechanism 4 includes a groove 41, a screw 42, a knob 43, and a top plate 44. The groove 41 is located on the side of the support leg 1 away from the horizontal plate 2. The screw 42 is threadedly installed on the inner wall of the U-shaped frame 3 on the side away from the horizontal plate 2. One end of the screw 42 is fixedly installed with the knob 43, and the end of the screw 42 near the support leg 1 is rotatably installed with the top plate 44, which is located in the groove 41; the leveling mechanism 5 includes a reinforcing rib 51, a first shaft frame 52, and a laser leveling device 53. The reinforcing rib 51 is fixedly installed on the bottom of the horizontal plate 2. The reinforcing rib 51 is rotatably connected to the first shaft frame 52 on both sides. The bottom of the first shaft frame 52 is fixedly installed to the laser leveling device 53. The limiting component 6 includes a through hole 61 and a limiting block 62. The through hole 61 is opened on one side of the two sets of horizontal plates 2 that are close to each other. Two sets of limiting blocks 62 are provided, and the two sets of limiting blocks 62 are fixedly installed on both sides of the inner wall of the horizontal plate 2. The connecting mechanism 7 includes a second shaft frame 71, a telescopic rod 72 and a first round rod 73. Two sets of second shaft frames 71 are provided, and the two sets of second shaft frames 71 are movably connected to both sides of the horizontal plate 2. The inner wall of the second shaft frame 71 is connected to the first shaft frame 52. A round rod 73 is fixedly installed, and the first round rod 73 is located in the through hole 61. The second shaft bracket 71 is fixedly installed with the telescopic rod 72 on the side away from the horizontal plate 2. The adjustment mechanism 8 includes a third shaft bracket 81, a second round rod 82 and a connecting rod 83. The third shaft bracket 81 is movably connected to one side of the horizontal plate 2. The inner wall of the third shaft bracket 81 is fixedly installed with the second round rod 82. The second round rod 82 is located in the through hole 61. The second round rod 82 is located on the side where the two sets of limit blocks 62 are close to each other. The third shaft bracket 81 is fixedly installed with the connecting rod 83 on the side away from the horizontal plate 2. The support leg 1 is made of stainless steel.
[0026] like Figures 1 to 5As shown, the groove 41 allows the top plate 44 to move stably up and down on the inner wall of the support leg 1, preventing it from shifting. The screw 42, knob 43, and top plate 44 work together to push the top plate 44 against the support leg 1 by the user's rotation, thus allowing it to remain suspended at any height on the surface of the support leg 1. It also allows the support leg 1 to be adjusted for uneven ground to achieve stability. The reinforcing rib 51 strengthens the structure of the horizontal plate 2, ensuring sufficient strength. The first shaft bracket 52, in conjunction with the laser leveling device 53, uses laser to level the ground and adjusts the measurement range according to the height of the horizontal plate 2. The through hole 61 provides a stable limit for the second round rod 82, preventing violent shaking and jamming during adjustment. The limiting block 62 restricts the range of motion of the second round rod 82. The second shaft 71, telescopic rod 72, and first round rod 73 work together to connect the two sets of horizontal plates 2 and keep them level and perpendicular. This allows the two sets of laser leveling devices 53 to measure more accurately and efficiently. The third shaft 81, second round rod 82, and connecting rod 83 work together to slide within the through hole 61 to make the connecting rod 83 vertical or inclined. When the connecting rod 83 is vertical, it will push the two sets of horizontal plates 2 to the sides, thereby increasing the distance between the horizontal plates 2 and adjusting the detection area of the laser leveling device 53. The stainless steel surface is smooth and highly corrosion-resistant, ensuring that the support leg 1 will not rust or corrode during long-term use. It also allows the U-shaped frame 3 to slide smoothly on the surface of the support leg 1, thus saving manpower.
[0027] Working principle: During operation, the support leg 1 is first placed on a flat surface. Then, the user turns the knob 43 to rotate the screw 42. When the screw 42 rotates, it will move the top plate 44 to one side. When the top plate 44 moves, it will no longer be pressed against the groove 41. At this time, the user can adjust the height of the horizontal plate 2 by raising it. When the height is adjusted to a suitable level, the user turns the knob 43 again to make the top plate 44 press against the groove 41 to fix the horizontal plate 2. Then, the laser leveling device 53 is activated to level the ground. When it is necessary to adjust the length of the horizontal plate 2 to expand the detection range of the laser leveling device 53, the user only needs to pull one set of horizontal plates 2 to one side. Then, the second round rod 82 will slide in the through hole 61, and the connecting rod 83 will slowly become vertical, thereby expanding the distance between the two sets of horizontal plates 2. At the same time, the telescopic rod 72 will extend and retract to ensure a stable connection between the two sets of horizontal plates 2.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
