Description

Technical Field

[0001] This application relates to the technical field of ground leveling, and in particular to a floor leveling device. Background Technology

[0002] A leveling layer is a base layer laid to level unevenness or slope in the structural concrete layer. Traditional floor or ground (hereinafter referred to as floor) construction generally includes a dedicated leveling layer to facilitate surface layer construction and ensure flatness after floor construction. The traditional construction process for floor leveling layers involves first cleaning the structural base surface, then applying cement slurry, creating mortar spots and screeds, and finally applying a cement mortar base for leveling. This method is relatively complex, prone to problems such as hollow areas and sandiness, and has a long construction period.

[0003] In traditional construction projects, leveling concrete or mortar floors is done manually. The mortar is spread and leveled by hand, and the quality of the work is highly dependent on the skill level of the workers. To achieve a better result, the surface is often repeatedly smoothed to control the height difference and flatness of the floor. This process is difficult, time-consuming, and labor-intensive. Summary of the Invention

[0004] To facilitate the leveling of concrete floors, this application provides a floor leveling device.

[0005] The floor leveling device provided in this application adopts the following technical solution:

[0006] A floor leveling device includes a leveling plate and two sets of support bases. The two sets of support bases are located at both ends of the leveling plate. Each set of support bases is provided with a horizontal guide rail. A slider is slidably mounted on the horizontal guide rail and slides along the length of the horizontal guide rail. The leveling plate is connected between the two sliders. A first adjusting element for adjusting the height of the horizontal guide rail is provided on the support base. A connecting pipe is provided on the leveling plate, and display tubes, which are transparent flexible tubes, are connected to both ends of the connecting pipe. The two display tubes and the connecting pipe are arranged in a U-shape. A second adjusting element for adjusting the height of the leveling plate is provided on the slider.

[0007] By adopting the above technical solution, the device is placed on the ground that needs to be leveled, and a certain volume of water is filled into the display tubes so that the liquid level can be seen in both display tubes. The height of the horizontal guide rail is adjusted by the first adjusting component, thereby adjusting the height of both sides of the leveling plate to initially determine the thickness of the concrete layer. Then, the liquid level in the display tubes on both sides is read, and the position of the leveling plate is adjusted by the second adjusting component so that the bottom surface of the leveling plate is on the horizontal line. Then, concrete is filled, and the leveling plate is moved to level the surface of the ground formed by the concrete, thereby facilitating the leveling of the floor, reducing the difficulty of construction leveling, and saving time and labor.

[0008] Optionally, the first adjusting component includes a first screw threaded onto the support base, the rotation axis of the first screw being in the vertical direction, and a connecting block being provided on the horizontal guide rail, the first screw being rotatably connected to the connecting block.

[0009] By adopting the above technical solution, the first screw is rotated, and the first screw rotates relative to the support base, thereby adjusting the length of the first screw within the support base, so as to adjust the position of the horizontal guide rail, and thus initially adjust the height position of the plate.

[0010] Optionally, the second adjusting component includes a second screw rotatably mounted on the slider, the rotation axis of the second screw being vertical, and adjusting blocks being provided at both ends of the finding plate. The two adjusting blocks are respectively threaded onto the second screw of the two sliders, and one end of the second screw extends outside the slider.

[0011] By adopting the above technical solution, after reading the liquid level on the display tube, the second screw is rotated, which drives the adjusting block to move, thereby adjusting the height of the leveling plate so that the two ends of the leveling plate are parallel to the liquid level at both ends, thus making the leveling plate horizontal.

[0012] Optionally, a rack is provided inside the horizontal guide rail, the length direction of the rack is along the length direction of the horizontal guide rail, a gear is rotatably provided on the slider, the gear meshes with the rack, and a motor for driving the gear to rotate is provided on the slider.

[0013] By adopting the above technical solution, the motor is started, the motor drives the gear to rotate, the gear moves on the rack in the slide rail, thereby driving the slider to move, so as to drive the leveling plate to move horizontally and level the floor.

[0014] Optionally, the leveling plate includes multiple leveling segments spliced ​​together. One end of each leveling segment is provided with a splicing block, and the other end of each leveling segment is provided with a splicing groove. The splicing block is inserted into the splicing groove. A connecting bolt passes through each leveling segment and is inserted into the splicing groove. The connecting bolt is threadedly connected to the splicing block.

[0015] By adopting the above technical solution, different numbers of leveling sections are selected and spliced ​​together according to the width of the floor. During splicing, the splicing block is inserted into the splicing groove, and the connecting bolt is threaded onto the splicing block, thereby realizing the connection of two adjacent leveling sections and improving the applicability of the device.

[0016] Optionally, the connecting pipe includes multiple pipe segments spliced ​​together, one end of each pipe segment is rotatably fitted with a connecting collar, the connecting collar is coaxially arranged with the pipe segment, and the other end of the pipe segment is threaded into the connecting collar.

[0017] By adopting the above technical solution, the pipe segments on the connecting pipe correspond to the leveling segments. While splicing the leveling segments, the pipe segments are inserted into the connecting collar, and the connecting collar is rotated to thread the end of the pipe segment into the connecting collar, thereby realizing the connection of the connecting pipe.

[0018] Optionally, the slider is provided with a first scale, which is located on the side close to the display tube and is set in the vertical direction.

[0019] By adopting the above technical solution, after the liquid level in the display tube stabilizes, the liquid level height at both ends can be read by the first scale. Based on the height difference of the liquid level, the height of the leveling plate at one end can be adjusted to make the leveling plate horizontal. Therefore, only one side of the leveling plate needs to be adjusted, which is more convenient and faster.

[0020] Optionally, a second scale is provided on the support base, the second scale is arranged in a vertical direction, and the second scale extends above the connecting block.

[0021] By adopting the above technical solution, the setting of the second scale is beneficial to accurately read the adjustment height when adjusting the horizontal guide rail, so as to set different concrete thicknesses.

[0022] Optionally, the top end of the display tube is provided with a cap for opening and closing the display tube, and the cap is threadedly connected to the display tube.

[0023] By adopting the above technical solution, when the device is moved, the end cap is threadedly connected to the display tube to prevent water from flowing out of the display tube. When measurement is required, the end cap is opened to allow both ends of the display tube to communicate with the atmosphere, thus avoiding the need to add water repeatedly during use and facilitating the use of the device.

[0024] Optionally, the horizontal guide rail is provided with a groove, the slider is slidably connected in the groove, a roller is rotatably provided on the slider, the roller abuts against the inner wall of the horizontal guide rail, the roller is located in the groove, and a limiting part is provided on the side wall of the groove to restrict the roller from moving out of the side of the horizontal guide rail.

[0025] By adopting the above technical solution, the limiting part restricts the roller from moving out of the side of the horizontal guide rail, thereby avoiding the possibility of the slider moving out of the side of the horizontal guide rail. Furthermore, the setting of the roller is conducive to the movement of the slider within the horizontal guide rail, which is beneficial to the movement of the flat plate.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Place the device on the ground that needs to be leveled, fill the display tube with a certain volume of water so that the liquid level can be seen on both ends of the display tube. Adjust the height of the horizontal guide rail by the first adjusting component, thereby adjusting the height of both sides of the leveling plate to initially determine the thickness of the concrete layer. Then read the liquid level in the display tubes on both sides, and adjust the position of the leveling plate by the second adjusting component so that the bottom surface of the leveling plate is on the horizontal line. Then fill the concrete and move the leveling plate to level the surface of the concrete ground, thereby facilitating the leveling of the floor, reducing the difficulty of construction leveling, and saving time and effort.

[0028] 2. Select different numbers of leveling sections according to the width of the floor and splice them together. When splicing, insert the splicing block into the splicing groove and use connecting bolts threaded through the splicing block to achieve the connection of two adjacent leveling sections and improve the applicability of the device.

[0035] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0036] This application discloses a floor leveling device. (Refer to...) Figure 1 , Figure 2 and Figure 3 The floor leveling device includes a leveling plate 1 and two sets of support bases 2, located at opposite ends of the leveling plate 1. Each set of support bases 2 is equipped with a horizontal guide rail 3. Each support base 2 includes two vertical support rods 201, and the horizontal guide rail 3 is connected to the two vertical support rods 201 on the same side. A slider 4 is slidably connected to the horizontal guide rail 3, sliding along its length. The leveling plate 1 is connected between the two sliders 4. A first adjusting element for adjusting the height of the horizontal guide rail 3 is provided on the support base 2. A connecting pipe 5 is connected to the leveling plate 1. Multiple clips are welded and fixed to the leveling plate 1, and the connecting pipe 5 is fastened within these clips. Both ends of the connecting pipe 5 are connected to display tubes 6, which are transparent flexible tubes for easy observation of the liquid level and for adjusting the height of the connecting pipe 5. The two display tubes 6 and the connecting pipe 5 are arranged in a U-shape. A second adjusting element for adjusting the height of the leveling plate 1 is provided on the slider 4.

[0037] Place the device on the ground that needs to be leveled, fill a certain volume of water into the display tube 6 so that the liquid level can be seen in both display tubes 6, forming a communicating vessel. Adjust the height of the horizontal guide rail 3 so that the height of both sides of the leveling plate 1 can be initially adjusted according to the thickness of the concrete layer. Then read the liquid level in the display tubes 6 on both sides and adjust the position of the leveling plate 1 so that the bottom surface of the leveling plate 1 is on the horizontal line. Then fill the concrete and move the leveling plate 1 to level the surface of the ground formed by the concrete.

[0038] Reference Figure 1 and Figure 3The first adjusting component includes a first screw 7 threaded onto the support vertical rod 201. The rotation axis of the first screw 7 is vertical. A connecting block 8 is welded and fixed to the horizontal guide rail 3. The first screw 7 is rotatably connected to the connecting block 8. The top of the first screw 7 passes through the connecting block 8 and extends from the top of the connecting block 8 to the outside of the connecting block 8. The top of the first screw 7 has an internal hexagonal groove 24 for rotating the first screw 7. A bearing 25 is sleeved on the first screw 7 and installed inside the connecting block 8. A limiting ring 26 for preventing the bearing 25 from falling is welded and fixed to the first screw 7. When it is necessary to adjust the position of the horizontal guide rail 3, a hexagonal wrench is used to rotate the first screw 7. The first screw 7 rotates relative to the support base 2, thereby adjusting the length of the first screw 7 within the support base 2, thus initially adjusting the height position of the leveling plate 1.

[0039] Reference Figure 1 and Figure 3 A second scale 19 is fixedly installed on the supporting vertical rod 201. The second scale 19 is set vertically and extends above the connecting block 8. When adjusting the horizontal guide rail 3, the adjustment height is accurately read through the second scale 19 to facilitate setting different concrete thicknesses. The second scale 19 abuts against the side wall of the connecting block 8, thereby restricting the synchronous rotation of the supporting vertical rod 201 and the first screw 7.

[0040] Reference Figure 2 and Figure 4 The second adjusting component includes a second screw 9 rotatably connected to the slider 4. The slider 4 has an adjusting groove 27, and the second screw 9 is rotatably connected within the adjusting groove 27. The rotation axis of the second screw 9 is vertical. Adjusting blocks 10 are welded and fixed to both ends of the leveling plate 1. The two adjusting blocks 10 are threaded onto the second screw 9 of the two sliders 4 respectively. One end of the second screw 9 extends through the slider 4 and beyond it. A handle is welded and fixed to the end of the second screw 9 extending beyond the slider 4. Rotating the handle rotates the second screw 9. After reading the liquid level on the display tube 6, rotating the second screw 9 causes the adjusting blocks 10 to move, thereby adjusting the height of the leveling plate 1 and ensuring that the leveling plate 1 is horizontal.

[0041] Reference Figure 2 and Figure 4A rack 11 is welded and fixed to the inner wall of the horizontal guide rail 3. The length of the rack 11 is along the length of the horizontal guide rail 3. A gear 12 is rotatably connected inside the slider 4. The axis of rotation of the gear 12 is vertical. The gear 12 meshes with the rack 11. A motor 13 is installed on the slider 4 to drive the gear 12 to rotate. The output shaft of the motor 13 is connected to the gear 12. When the motor 13 is started, the motor 13 drives the gear 12 to rotate. The gear 12 moves on the rack 11 inside the slide rail, thereby driving the slider 4 to move. This facilitates the horizontal movement of the leveling plate 1, leveling the concrete and achieving the leveling of the floor.

[0042] Reference Figure 2 and Figure 4 A groove 21 is provided on the horizontal guide rail 3, extending along its length. A slider 4 is slidably connected within the groove 21. Two rollers 22 are rotatably connected to the slider 4, with their rotation axes horizontal. The rollers 22 are located at the bottom and top of the slider 4, respectively, and abut against the inner walls of the upper and lower sides of the horizontal guide rail 3. The rollers 22 are situated within the groove 21, and a limiting part 23 is integrally formed on the side wall of the groove 21 to restrict the rollers 22 from sliding out from the side of the horizontal guide rail 3. The limiting part 23, combined with the groove 21, makes the horizontal guide rail 3 a T-shaped groove, thus limiting the sliding out of the rollers 22. The limiting part 23 restricts the rollers 22 from sliding out from the side of the horizontal guide rail 3, and the arrangement of the rollers 22 facilitates the movement of the slider 4 within the horizontal guide rail 3, thereby facilitating the movement of the flat plate 1.

[0043] Reference Figure 1 and Figure 5 The leveling plate 1 comprises multiple leveling segments 101 joined together. A connecting block 14 is welded to one end of each leveling segment 101, and a connecting groove 15 is formed at the other end of each leveling segment 101, into which the connecting block 14 is inserted. The leveling segments 101 at both ends of the leveling plate 1 are welded to adjusting blocks 10. Connecting bolts 16 pass through each leveling segment 101 and are threaded into the connecting groove 15, thus connecting the connecting bolts 16 to the connecting block 14. The connecting pipe 5 is formed by splicing multiple pipe segments 501 together. The pipe segments 501 are correspondingly set with the leveling section 101. One end of the pipe segment 501 is rotatably fitted with a connecting collar 17. The connecting collar 17 is coaxially set with the pipe segment 501. The inner wall of the connecting collar 17 is provided with internal threads. The end of the pipe segment 501 is provided with external threads. The other end of the pipe segment 501 is threaded into the connecting collar 17. A sealing ring is also glued to the end of the pipe segment 501. The sealing ring is a rubber ring. The sealing ring reduces the possibility of water leakage at the connection between the two pipe segments 501.

[0044] Different numbers of leveling sections 101 are selected and spliced ​​together according to the width of the floor. During splicing, splicing blocks 14 are inserted into splicing grooves 15, and connecting bolts 16 are threaded onto splicing blocks 14, thus connecting two adjacent leveling sections 101. Simultaneously, pipe sections 501 are inserted into connecting collars 17, and the connecting collars 17 are rotated to thread the end of pipe sections 501 into the connecting collars 17, thus connecting the connecting pipes 5. This allows for the selection of different numbers of leveling sections 101 according to different scenarios.

[0045] Reference Figure 1 and Figure 2 A first scale 18 is fixedly embedded on the slider 4. The first scale 18 is located on the side near the display tube 6 and is set vertically. After the liquid level in the display tube 6 stabilizes, the liquid level at both ends can be read through the first scale 18. Based on the height difference of the liquid level, the height difference of the leveling plate 1 at one end can be adjusted to make the leveling plate 1 horizontal. Therefore, only one side of the leveling plate 1 needs to be adjusted, which is more convenient and faster.

[0046] Reference Figure 1 and Figure 3 The top of the display tube 6 is connected to a cap 20 for opening and closing the display tube 6. The outer end of the cap 20 has an external thread, and the inside of the top of the display tube 6 has an internal thread. The cap 20 is threaded onto the display tube 6. When moving the device, the cap 20 is threaded onto the display tube 6 to prevent water from flowing out of the display tube 6. When measurement is required, the cap 20 is opened to allow both ends of the display tube 6 to communicate with the atmosphere, avoiding the need for repeated water addition during use.

[0047] The implementation principle of the floor leveling device in this application embodiment is as follows: A support base 2 is placed on the ground to be leveled. A certain volume of water is filled into the display tube 6 so that the liquid level can be seen in both ends of the display tube 6. The first screw 7 is rotated using a tool to adjust its length within the support base 2, thereby adjusting the height of the horizontal guide rail 3. This allows for initial adjustment of the height on both sides of the leveling plate 1 based on the set thickness of the concrete layer. The liquid level in the display tubes 6 on both sides is then read. The second screw 9 is rotated, causing the adjusting block 10 to move, thus adjusting the position of the leveling plate 1 so that its bottom surface is on a horizontal line. Concrete is then filled in, and the leveling plate 1 is moved to level the concrete surface of the ground. This facilitates floor leveling, reduces the difficulty of construction leveling, and saves time and effort.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
