[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-4 The utility model discloses a leveling device for floor paving, comprising a template 1 connected to the walls on both sides of a room at both ends, a liftable leveling member 2 is arranged on the template 1, a scraper 6 is arranged on the leveling member 2, the leveling member 2 comprises an upper horizontal plate 202 located at the top, a bubble level 3 is arranged at one end of the upper horizontal plate 202, the bubble level 3 comprises a rigid shell 301 connected to the upper horizontal plate 202, the rigid shell 301 is arranged along the length direction, the rigid shell 301 is a hollow cylindrical structure, the interior of the rigid shell 301 is filled with alcohol with bubbles, an observation window 302 is embedded and installed on the top of the rigid shell 301, the observation window 302 is made of transparent glass, and a scale line 303 is arranged in the middle of the outer wall of the rigid shell 301.

[0025] A casting area is formed in the area enclosed by the two formworks 1 and the two walls. After the formwork 1 is fixed between the two walls, the leveling piece 2 is adjusted to a horizontal position with its bottom surface at the same height as the floor elevation. Then, the slurry is poured in and the slurry is scraped along the extension direction of the leveling piece 2 with a scraper to make the floor reach the elevation and remain level.

[0026] Among them, the rigid shell 301 and the upper horizontal plate 202 are an integrally formed structure, which can not only improve the overall structural strength of the leveling piece 2 and the bubble level 3 and reduce bending, but also enable the bubble level 3 itself to maintain real-time synchronous adjustment when the leveling piece 2 is adjusted until the leveling piece 2 reaches the floor elevation and is horizontal. There is no need to set up a level meter separately to calibrate the level of the leveling piece 2, which reduces the work of adjusting the level meter separately and simplifies the operation.

[0027] An oblong slot hole 201 is provided on the upper horizontal plate 202, and an adjusting bolt 4 is passed through the oblong slot hole 201. The adjusting bolt 4 includes a bolt body 401. The lower part of the bolt body 401 is threadedly connected to the template 1, and the upper part of the bolt body 401 passes through the oblong slot hole 201. A supporting nut 402 and a fastening nut 403 are provided on the bolt body 401. The supporting nut 402 is located between the template 1 and the oblong slot hole 201, and the fastening nut 403 is located above the oblong slot hole 201.

[0028] The supporting nut 402 and the bolt body 401 can be welded, while the fastening nut 403 and the bolt body 401 are threaded. After judging which end of the leveling member 2 is higher and which end is lower by observing with the bubble level 3, the adjustment is made higher or lower according to the height difference between the two ends and the floor elevation. When adjusting, the bolt body 401 is turned, and the bolt body 401 drives the supporting nut 402 to rise or fall, so that the leveling member 2 is raised or lowered synchronously. When it is lowered to the predetermined position, the fastening nut 403 is turned to clamp the upper horizontal plate 202, thereby fixing the position of the leveling member 2.

[0029] The oblong slot hole 201 is convenient for adjusting the height of the end of the leveling member 2 in steps. Compared with the traditional standard round hole, the oblong slot hole 201 can avoid being stuck with the bolt body 401 during the step-by-step adjustment process.

[0030] The end of the upper horizontal plate 202 away from the bubble level 3 is connected to the vertical plate 203, the vertical plate 203 is in contact with the side wall of the template 1, the bottom of the vertical plate 203 is connected to the lower horizontal plate 204, and the scraper 6 is slidably connected to the lower horizontal plate 204.

[0031] Specific as Figure 4 As shown, by adjusting the height of the upper horizontal plate 202, the height of the lower horizontal plate 204 is adjusted so that the bottom surface of the lower horizontal plate 204 is the same as the floor elevation, thereby achieving a leveling effect, and then the slurry exceeding the floor elevation is scraped off by a scraper 6.

[0032] There are a plurality of oblong slot holes 201 , and the plurality of oblong slot holes 201 are evenly distributed on the upper horizontal plate 202 .

[0033] A plurality of oblong slot holes 201 are evenly distributed on the upper horizontal plate 202. When the overall length of the leveling member 2 is relatively short (no obvious deformation occurs), the adjusting bolts 4 can be passed through the oblong slot holes 201 located at the outermost ends of the upper horizontal plate 202 to improve the adjustment accuracy. If the overall length of the leveling member 2 is relatively long (slight deformation occurs), the two adjusting bolts 4 are passed through the oblong slot holes 201 close to the middle position of the ends of the upper horizontal plate 202 to reduce the degree of deformation of the leveling member 2.

[0034] A connecting groove is provided at the bottom of the scraper 6 , and the thickness of the connecting groove is equal to the thickness of the lower horizontal plate 204 , so that the bottom end of the scraper 6 is at the same height as the bottom end of the lower horizontal plate 204 .

[0035] Specifically, the height of the connecting groove is the same as the height of the lower horizontal plate 204, so that the bottom surface of the scraper 6 is flush with the bottom surface of the lower horizontal plate 204. When the bottom surface of the lower horizontal plate 204 is adjusted to be the same as the floor elevation, the height of the bottom surface of the scraper 6 is also the same as the floor elevation.

[0036] The template 1 is a channel steel, which is laid horizontally, with the openings of the two templates 1 facing outwards, the vertical plate 203 is fitted with the side wall of the channel steel, and the scraper 6 is slidably installed between the two leveling members 2.

[0037] When in use, the opening of the channel steel faces outwards, with the two ends resting against the walls on both sides. The structure has high strength and is easy to obtain.

[0038] The template 1 is provided with fixing bolts 5 , which pass through the upper and lower ends of the template 1 .

[0039] The fixing bolt 5 can be an expansion bolt, which can be screwed in from the top of the channel steel to facilitate disassembly and assembly.

[0040] Working principle: When in use, two templates 1 are fixed between two walls by fixing bolts 5, and both ends of the template 1 are connected to the wall surface. Then, according to the position of the bubble in the bubble level 3, it is directly judged whether the two ends of the leveling piece 2 are on the same horizontal plane, and it can be judged which end of the leveling piece is higher and which end is lower;

[0041] By screwing the adjusting bolt 4 on the upper horizontal plate 202, the two ends of the leveling member 2 are adjusted to rise or fall, so that the two ends of the leveling member 2 are at the same horizontal height, and the bottom surface of the leveling member is the same as the floor elevation, the slurry is poured between the two templates, and then the slurry is scraped flat with a scraper.
