Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a leveling device. Background Art

[0002] In construction, it is usually necessary to level the concrete on the ground, wall and ceiling to facilitate the decoration of the house. Leveling is the process of ensuring that the ground, wall or other structural surfaces meet the horizontal or vertical state required by the design. At present, plaster cakes and cement mortar reinforcement are commonly used for leveling, which usually requires reinforcement work on the surface. In traditional reinforcement work, the laser leveler is first fixed on the surface, and the plastering thickness is determined by manual plaster cakes. Then the plaster cakes are connected with reinforcement materials, and the upper surface of each rib is located in the same horizontal plane through the laser leveler. After the ribs are fixed, the required mortar or mortar is filled between the ribs, and then the surface of the two ribs is used as the basis. Use a special long rod to scrape back and forth to remove the mortar that is higher than the ribs to obtain a flat base surface.

[0003] In the prior art, punching and leveling are usually done manually, and the quality of construction depends entirely on the workers' proficiency and sense of responsibility. In addition, in the process of punching and leveling, the punching materials include metal strips, plastic strips, leftover wall tiles or floor tiles, and ribs formed by solidification of gypsum or cement mortar, etc., which further increases the uncertainty of construction quality. Therefore, in order to achieve better construction results, secondary leveling is often required, which is time-consuming and labor-intensive. Utility Model Content

[0062] Optionally, the four connecting plates 41 are mounted on the two fourth plates 12 by means of screws. Thus, the connecting plates 41 mounted by means of screws are easier to disassemble and assemble.

[0063] One ends of the four mounting plates 42 are mounted on the four connecting plates 41 respectively, and the four mounting plates 42 are arranged in a one-to-one correspondence with the four connecting plates 41 .

[0064] The four mounting plates 42 are each provided with mounting holes, and the four thread sleeves 43 are respectively mounted on the four mounting plates 42, and the four thread sleeves 43 are arranged one-to-one with the four mounting plates 42, and the four thread sleeves 43 are coaxially arranged with the corresponding mounting holes, that is, the axis of each thread sleeve 43 and the axis of the corresponding mounting hole are located on the same straight line.

[0067] In state one, the other ends of the four ear plates 7 extend along the first direction and extend out of the third plate 11, and one ends of the four ear plates 7 extending out of the third plate 11 are located on the same horizontal plane. In this way, when the first frame 1 needs to be adjusted, first use an infrared level to draw a horizontal or vertical standard line, and then adjust the first adjustment component 4 or the second adjustment component 5 so that the top ends of the four ear plates 7 on the first frame 1 are all located on the standard line, thereby assisting the first adjustment component 4 and the second adjustment component 5 to adjust the horizontality and verticality of the first frame 1.

[0068] In state two, the other ends of the four ear plates 7 extend along the second direction, and the projections of the four ear plates 7 in the third direction are located within the projection of the third plate 11 in the third direction.

[0069] Optionally, four positioning blocks 8 are further included, which are respectively fixedly mounted on the four ear plates 7, and the positioning blocks 8 are used to limit the rotation angle of the ear plates 7. Specifically, when the ear plates 7 are in state two, the positioning blocks 8 are located at the top end of the ear plates 7, and the bottom end of the positioning blocks 8 is in contact with the top end of the third plate 11. When it is necessary to use the leveling device provided by the embodiment of the utility model, the ear plates 7 are rotated so that the positioning blocks 8 rotate along with the rotation of the ear plates 7 until the right end of the positioning blocks 8 is in contact with the top end of the third plate 11, so that the ear plates 7 are in state one. In this way, through the setting of the four positioning blocks 8, each ear plate 7 can only rotate ninety degrees each time it rotates, so that the top ends of the four ear plates 7 are located in the same plane, which facilitates the adjustment of the first frame 1.

The inner diameter of the clearance holes is smaller than the outer diameter of the countersunk screws 51 . In the working state, the four cover plates 52 are respectively pressed against the four countersunk screws 51 .

[0073] Through the above structure, by the provision of four countersunk screws 51, it is convenient to install the leveling device provided by the embodiment of the utility model on a wall or a top wall, and it is only necessary to rotate the cover plate 52 and screw the countersunk screws 51 through the through holes into the wall; when it is necessary to adjust the top ends of the four ear plates 7 to be located in the same plane, first rotate the cover plate 52 to the top of the countersunk screws 51, so that the cover plate 52 is pressed against the countersunk screws 51, and at the same time, the axis of the clearance hole and the through hole are located in the same straight line, and then screw the countersunk screws 51 from the clearance hole. Through the provision of the cover plate 52, the distance between the mounting plate 42 and the wall or the top wall increases as the countersunk screws 51 are screwed out, and the distance between the mounting plate 42 and the wall or the top wall decreases as the countersunk screws 51 are screwed in, thereby achieving the purpose of effectively adjusting the first frame 1.

[0074] An optional implementation of the present embodiment is as follows: a side of the first plate 21 close to the second plate 22 and a side of the second plate 22 close to the first plate 21 both have an angle α with the plane where the second direction is located, that is, a vertical distance between a side of the first plate 21 close to the second plate 22 and a side of the second plate 22 close to the first plate 21 gradually increases along the direction of the first frame 1 pointing to the plate assembly 2. In this way, when making the base surface, the cross-sectional area of ​​the base surface gradually increases from the top end to the bottom end. Therefore, when the leveling device provided by the embodiment of the utility model is taken out from the mortar base surface, the probability of the mortar base surface being damaged is reduced.

[0075] Optionally, the range of the angle α is: 20°≤α<90°. Exemplarily, the angle α can be 20°, 30°, 40°, 50°, 60°, 70°, 80°, etc. If the angle is too small, it will be inconvenient to manufacture, and if the angle is too large, it will cause failure.

[0076] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model.
