In some embodiments, the fixing part 400 can be connected to the surface of the concrete on the one hand to fix the entire leveling device in the concrete; on the other hand, the fixing part 400 can also be connected to the installation part 301 to keep the leveling mechanism 100 stable during operation performance, and the height of the leveling mechanism 100 can be adjusted according to working conditions.

In some embodiments, the fixing member 400 may include a bracket 401 and a support tube 402 , and the support tube 402 may be fixed by the bracket 401 and then connected to the installation part 301 .

In some embodiments, the connecting member 300 may further include a clip 304 (as shown in FIG. 8 ), which may be fixedly connected with the installation part 301, and the clip 304 may fix the installation part 301 to other objects.

In one application scenario, during the pouring process of the floor slab, the steel skeleton will be prepared in advance, and then the concrete will be poured. The construction personnel can clamp the installation part 301 on the vertical steel bar 305 through the clamp 304. When the height adjustment is required, release the clamp. The hoop 304 can be locked when the position is appropriate. The construction personnel can adjust the specific form of the fixing part 400 according to the specific conditions of the concrete, so as to fix the installation part 301 more effectively and conveniently, and ensure that the leveling mechanism 100 has good stability and stability when leveling the surface of different concrete. High leveling efficiency.

In some embodiments, the connection manner between the installation part 301 and the fixing member 400 may include screw connection. The precision of the screw connection is high, which is helpful for adjusting the installation height of the installation part 301 and improving the leveling accuracy of the leveling mechanism 100 .

Specifically, one end of the mounting part 301 connected to the fixing piece 400 can be provided with a connecting rod 303, the support cylinder 402 can be provided with an internal thread, and the inner upper end of the support cylinder 402 can be sleeved with an adjustment screw 403, and the adjustment screw 403 can be connected to the support The barrel 402 is threaded, so that construction workers can adjust the height of the leveling mechanism 100 by adjusting the screw 403 . The upper end of the adjusting screw 403 is provided with a mounting hole, and the connecting rod 303 is inserted into the mounting hole to realize the connection between the fixing part 400 and the mounting part 301 . Wherein, the adjusting screw 403 can be a hollow structure, which can reduce the overall weight and facilitate the construction personnel to carry it.

In another embodiment, one end of the mounting part 301 connected to the fixing member 400 can be provided with a connecting rod 303, the upper end of the support cylinder 402 can be provided with an external thread, and the external thread can be sleeved with an adjusting nut 405 (as shown in FIG. 9 ).

In one application scenario, the leveling mechanism 100 is fixed on the bracket 401. On the one hand, the leveling mechanism 100 can be fixed, so that the leveling mechanism 100 can adapt to different concretes (such as floors, etc.), and the practicability of the leveling device can be improved. On the one hand, The height of the leveling concrete can be controlled by controlling the leveling mechanism 100 by adjusting the height of the support. When the construction personnel determine the elevation, they generally use an infrared device to determine it, and then adjust the bracket to the corresponding height position. However, due to the structural characteristics of the bracket, the construction personnel need to move the bracket feet of the bracket when adjusting the height of the bracket, so the height of the bracket cannot be adjusted accurately, and the error when adjusting the height is relatively large (usually centimeter level), which cannot meet the flatness of the concrete . Therefore, a mechanism for more precise height adjustment is needed, and the mounting part 301 is threadedly connected with the fixing part 400, and the elevation (millimeter level) is adjusted more precisely through the adjustment screw 403 or the adjustment nut 405, so as to improve the leveling accuracy of the leveling device.

In some embodiments, the bracket 401 can be a disposable bracket 401, and the disposable bracket 401 is used to be fixedly connected with the concrete bottom form and embedded in the concrete after the floor concrete is poured, and the disposable bracket 401 and the support tube 402 can be are detachably attached. For example, snap-fit, threaded connection, etc. or any combination thereof.

In some embodiments, the detachment of the bracket 401 can be realized by screw connection. Specifically, in some embodiments, the disposable bracket 401 may be provided with a nut (not shown in the figure), and the support cylinder 402 may be provided with a screw rod (not shown in the figure). In some embodiments, studs 404 (as shown in FIGS. 6-9 ) can also be provided on the disposable support 401, and internal threads can be provided on the support cylinder 402. The design of the internal threads can reduce the time spent on pouring concrete. pollution in.

After the construction personnel complete the leveling work of the concrete, if it is an ordinary support, the support needs to be recycled, otherwise the overall structure of the concrete may be affected. And in the process of taking out the support, on the one hand, the surface of the leveled concrete will definitely be damaged, which may have a strong impact on the smoothness of the leveled concrete surface, on the one hand, it will also increase the workload of the construction personnel. After adopting the disposable support 401, it is unnecessary to reclaim the disposable support 401, and the remaining parts (such as the support cylinder) of the leveling device except the disposable support 401 can be directly disassembled, and then a small amount of concrete can be filled. . While saving manpower, it also avoids damage to the leveled concrete surface.

Specifically, the concrete bottom form may refer to: in the process of pouring concrete on the floor, it is necessary to make a support form to surround the concrete, and the bottom form is the bottom support form. In some embodiments, the material of the bottom mold can be wood board, plastic board, aluminum alloy board, laminated board and so on.

In some embodiments, the disposable bracket 401 can also be fixedly connected to the bottom mold by means such as riveting, welding, bolting, etc., to ensure the stability and improvement of the leveling mechanism 100 connected to the disposable bracket 401 during work. leveling precision.

In one application scenario, when the construction personnel level the concrete surface, they first embed the disposable bracket 401 in the concrete of the floor slab and fix it with the concrete base form, then connect the support tube 402 with the disposable bracket 401, and then Connect the installation part 301 and the leveling mechanism 100 in sequence. After the overall connection of the leveling device is completed, the concrete surface is leveled. After the leveling is completed, the rest of the leveling device except the disposable bracket 401 is disassembled, and the disposable bracket 401 is left in the concrete and paved with concrete remaining potholes.

In some embodiments, the height of the disposable stand 401 may be slightly lower than the elevation. After the concrete is poured, the potholes left on the concrete surface after the supporting cylinder 402 is dismantled can be filled directly. If the disposable support 401 is higher than the elevation, a part of the disposable support 401 will protrude from the concrete surface after the support cylinder 402 is disassembled, and the disposable support 401 needs to be processed. Therefore, when the disposable bracket 401 is lower than the elevation, the above-mentioned steps can be avoided and construction steps can be reduced.

The rest of the structure of the fixing member 400 may be the same as that of the foregoing embodiments, and will not be repeated here.

Fig. 10 is a structural schematic diagram of an embodiment of the adjustment mechanism of the present application. As shown in FIG. 10 , in some embodiments, the fixing member 400 may include a bracket 401 and a mounting frame 406, the mounting frame 406 may be connected to the bracket 401, and at least one sliding block 408 may be arranged on the mounting frame 406, and the sliding block 408 may Connected with the installation part 301, the slider 408 can move up and down relative to the installation frame 406 to drive the installation part 301 to move up and down, so as to adjust the height of the leveling mechanism 100 and improve the leveling stability.

In some embodiments, the slider 408 may be other objects capable of sliding, such as a sliding rod, a sliding piece, a hinge, etc., or any combination thereof. Specifically, one end of the sliding rod can pass through the mounting bracket 406, and the side wall of the sliding rod is fixed to the fixed part. The construction personnel can control the height of the mounting part 301 by pulling up or lowering the sliding rod, thereby adjusting the height of the leveling mechanism 100. . In addition, it can also be a combination of a sliding sheet and a sliding rod. The sliding sheet is fixed to the mounting part 301, one end of the sliding rod is fixed to the sliding sheet, and the other end passes through the mounting frame 406, and the construction personnel can control it by pulling up or lowering the sliding rod. The height of the mounting part 301 is used to adjust the height of the leveling mechanism 100 .

In some embodiments, the sliding block 408 can be detachably connected to the installation part 301, on the one hand, it improves the connection stability between the fixing part 400 and the leveling mechanism 100, and ensures that the leveling mechanism 100 will not shake when leveling. Or it is separated from the fixing part 400, affecting the leveling accuracy. On the other hand, it is convenient for construction personnel to carry and disassemble the leveling device, so as to improve construction efficiency.

In some embodiments, the outer wall of the mounting part 301 can be provided with a fixing protrusion (not marked in the figure), and the side wall of the slider 408 can be provided with a fixing concave hole corresponding to the fixing protrusion.

Therefore, on the one hand, the sliding block 408 drives the mounting part 301 to move up and down during the up and down movement, so as to achieve the purpose of height adjustment. On the other hand, when the moving assembly is leveling, it must come into contact with the protruding concrete or other impurities on the surface of the concrete, causing the entire leveling mechanism 100 to move up and down, affecting the leveling accuracy, so the mounting part 301 is limited relative to the slider The up and down movement of the 408 can effectively reduce the up and down movement of the leveling mechanism 100, improve the construction quality, facilitate the construction personnel to carry and disassemble the leveling device, and improve the construction efficiency.

In some other embodiments, the sliding block 408 and the installation part 301 may also be detachably connected by other means, such as hinge connection, plug connection, etc. or any combination thereof.

In some embodiments, the slider 408 and the installation part 301 may be fixedly connected, such as welding, nailing, etc. or any combination thereof. After the sliding block 408 is fixedly connected with the installation part 301, the movement of the leveling mechanism 100 can be further reduced, and the leveling quality can be improved.

In some embodiments, the slider 408 can be disposed between the upper and lower mounting frames 406 , and the upper mounting frame 406 can be provided with a rotating screw 407 , and the sliding block 408 can be threadedly connected with the mounting frame 406 by rotating the screw 407 . When the rotating screw 407 moves up and down, it will drive the slider 408 to move, thereby adjusting the height of the leveling mechanism 100 . Therefore, construction personnel can control the height of the leveling mechanism 100 by adjusting the up and down movement of the rotary screw 407 .

Specifically, as shown in FIG. 11 , there is a certain gap between the slider 408 and the mounting frames 406 on the upper and lower sides, so as to be able to move up and down therein. The inside of the slider 408 can be provided with an internal thread, the screw part of the rotary screw 407 can go deep into the slider 408 and be threadedly connected with the slider 408, and the head of the rotary screw 407 can pass through the mounting frame 406 and lean against the mounting frame 406 The upper end of the upper end is away from the side of the slide block 408, so that the construction personnel can control the rotating screw rod 407. When the construction worker rotates the head of the rotary screw rod 407, since the slider 408 is restricted by the inner wall of the mounting bracket 406, it cannot rotate, and can only move up and down with the rotation of the rotary screw rod 407, so as to adjust the leveling mechanism 100. high purpose.

In another embodiment, the head of the rotating screw 407 can go deep into the slide block 408 and be fixedly connected with it, and the screw part of the rotating screw 407 can pass through the mounting frame 406 and be screwed with the mounting frame 406, and the construction personnel can rotate the position of the mounting frame 406 The screw part of the rotating screw 407 outside the frame 406 can also achieve the purpose of adjusting the height of the leveling mechanism 100 .

Specifically, calibration can be carried out through an infrared device, a level bar, etc. After the levelness of the fine flat plate 102 is calibrated, the fine flat plate The leveling part of 102 is adjusted to be the same as the level of concrete (such as the level of concrete on the floor). Specifically, the level can be firstly adjusted through an infrared device, and then a rough height adjustment can be performed through the bracket 402 or the clamp 304, followed by, for example, controlling the slider 408 to adjust the height of the fine plate or the adjustment nut 405 etc. to adjust more precisely; finally push the fine plate 102 to slide on the sliding guide rail 103 of the fixed assembly 110 (such as the first horizontal column) to control the elevation of the concrete surface .

Wherein, construction personnel can adjust the height of the leveling mechanism 100 by rotating the rotating screw 407 located at the upper end of the slider 408 (for example, rotating counterclockwise to raise the height, and turning clockwise to lower the height).

In some embodiments, the stent 401 may also include a disposable stent 401 , and specific effects will not be repeated here.

In an application scenario, when two installation parts 301 are connected to one slider 408, the leveling device can be used to level the beams or both sides of the horizontal reinforcement on the same floor, for example, between two rooms on the same floor If there are beams or horizontal steel bars separating two rooms, the leveling device can be placed on the beams or horizontal steel bars to level the two rooms separated by beams or horizontal steel bars. That is, a leveling device can be used to level the floors of two rooms at the same time, and since the floors of the same floor have the same elevation, the construction personnel can control the movement of the slider 408 on one side of the shear wall to adjust the height. The height adjustment of the leveling device on the other side of the shear wall further improves the construction efficiency.

In some other embodiments, two sliders 408 may be provided on the mounting bracket 406, and the two sliders 408 may move relative to each other, and the opposite sides of the two sliders 408 may be respectively connected with a mounting part 301 , the height adjustment of the two installation parts 301 is completed by different sliders 408 respectively.
