Description

Technical Field

[0001] The present invention relates to the technical field of cement floor construction tools, and specifically to a floor cement leveling auxiliary tool. Background Art

[0002] In some special paving scenarios, for example, when paving a floor in the central area of a floor paved with marble or tiles, due to the different thicknesses of marble or tiles and the floor, a sunken cement floor is formed in the floor paving area, and the cement floor in the floor paving area needs to be leveled separately. In particular, in order to make the surface of the paved floor flush with the paving surface of the marble or tiles, the flatness requirement for the cement floor in the floor paving area is relatively high. In summary, the construction of leveling the sunken cement floor in the floor paving area is rather troublesome and difficult. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above technical problems, and thus provide a leveling auxiliary tool, which can more conveniently handle the leveling construction of the cement floor in the sunken paving area, and the flatness of the cement floor in the paving area is relatively high after the leveling construction.

[0004] To achieve the above purpose, an embodiment of the present invention provides a leveling auxiliary tool, including a first reference member, a second reference member, a connecting member connecting the first reference member and the second reference member, and a leveling member arranged through the connecting member. The bottom surfaces of the first reference member and the second reference member form the working reference surface of this leveling auxiliary tool. The working reference surface is parallel to the leveling working surface of the leveling member, and the setting position of the leveling working surface is lower than the working reference surface.

[0005] With the above structure, through the structural design of the leveling member arranged between the working reference surfaces and making the two parallel, the working reference surface is placed around the paving area and based on the ground in the surrounding high areas. The leveling member levels the sunken ground in the paving area. By simply adjusting the distance between the leveling working surface and the reference working surface, the leveling member can be operated to scrape the slurry for leveling by moving the connecting member. Thus, during the leveling process, there is no need to repeatedly and frequently control the height difference between the sunken area and the surrounding area, and the operation is convenient and efficient; and the leveling treatment can be completed by scraping the slurry once with the leveling member, and the flatness of the cement floor in the paving area is relatively high after the leveling construction.

[0006] Preferably, the connecting member can adjust its setting position on the first reference member and the second reference member.

[0007] Preferably, there is an inclination angle of 10° to 25° between the plane where the leveling member is located and the plane formed by the first reference member and the second reference member.

[0008] Preferably, the first reference member includes a first rod portion and a first reference portion provided at the bottom of the first rod portion, the second reference member includes a second rod portion and a second reference portion provided at the bottom of the second rod portion, and the first rod portion and the second rod portion are symmetrically arranged.

[0009] Preferably, two end portions of the connecting member can be slidably sleeved on the first rod portion and the second rod portion respectively, and are locked at their set positions on the first rod portion and the second rod portion through a screw structure.

[0010] Preferably, the leveling auxiliary tool includes a first leveling unit, a second leveling unit, and an extension unit. The first leveling unit includes a first reference member, a first connecting member connecting the first reference member, and a first leveling member provided through the first connecting member. The second leveling unit includes a second reference member, a second connecting member connecting the second reference member, and a second leveling member provided through the second connecting member. The extension unit includes an extension connecting member and an extension leveling member provided through the extension connecting member. The first leveling unit, the extension unit, and the second leveling unit are sequentially spliced and connected. The first connecting member, the extension connecting member, and the second connecting member constitute the connecting member, and the first leveling member, the extension leveling member, and the second leveling member constitute the leveling member.

[0011] Preferably, there are multiple extension units, and the multiple extension units can be spliced and connected to each other.

[0012] Preferably, the first reference portion includes a first sliding inclined surface, the second reference portion includes a second sliding inclined surface, and the inclination angles of the first sliding inclined surface and the second sliding inclined surface are 30° to 45°.

[0013] Preferably, the leveling member includes multiple leveling member monomers. The leveling member monomer close to the first reference member is fixedly arranged on the connecting member, the leveling member monomer close to the second reference member can be movably arranged on the connecting member, and the multiple leveling member monomers are hinged to each other.

[0014] Preferably, the connecting member can be telescoped.

[0015] In summary, compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. Through the structural design of the leveling member disposed between the working reference surfaces and making the two parallel, it can more conveniently handle the leveling construction of the cement floor in the sunken paving area, and the flatness of the cement floor in the paving area is relatively high after the leveling construction.

[0019] 4. Through the arrangement of multiple leveling member monomers, and the multiple leveling member monomers are hingedly connected to each other, so that the leveling member can be folded, making the leveling auxiliary tool convenient for storage, carrying and transportation.

Detailed Embodiments

[0028] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0029] Example 1: Reference Figure 1 A leveling aid is shown, comprising a first reference member 100, a second reference member 200, a connecting member 300 connecting the first reference member 100 and the second reference member 200, and a leveling member 400 arranged through the connecting member 300. The bottom surfaces of the first reference member 100 and the second reference member 200 form a working reference surface of the leveling aid, the working reference surface is parallel to the leveling working surface of the leveling member 400, and the setting position of the leveling working surface is lower than the working reference surface.

[0030] Specifically, in this embodiment, the first reference member 100, the second reference member 200, and the connecting member 300 are rod-shaped members made of metal, wood, plastic, etc. The first reference member 100 and the second reference member 200 have the same shape, and the two ends of the connecting member 300 are connected to the first reference member 100 and the second reference member 200 by welding, screwing, gluing, etc. to form a "冂"-shaped structure. The material of the leveling member 400 is the same as that of the aforementioned structure, preferably plastic, and the leveling member 400 is a thin plate, the upper edge of which is arranged parallel to the connecting member 300, and is fixedly mounted on the connecting member 300 by hot melting, screwing, gluing, etc.

[0031] In this embodiment, the bottom surfaces of the first reference member 100 and the second reference member 200 form the working reference surface of the leveling auxiliary tool. The working reference surface is parallel to the leveling working surface of the leveling member 400, and there is a height difference between the working reference surface and the leveling working surface, which is the drop between the two installation surfaces. Therefore, during construction, the height difference between the working reference surface and the leveling working surface is equal to the installation thickness difference. For example, if the thickness of the tile is 6mm, the thickness of the paved floor is 18mm, and the area around the floor paving area has been completed with tile paving, the height difference between the working reference surface and the leveling working surface is 18mm. If the area around the board paving area has not been completed with tile paving, the height difference between the working reference surface and the leveling working surface is 12mm. The first reference member 100 and the second reference member 200 are placed around the concave paving area. At this time, the leveling member 400 can level and scrape the cement in the concave floor paving area.

[0032] Example 2: Reference Figure 2 , Figure 3As shown, the difference between Embodiment 2 and Embodiment 1 is that the connecting member 300 can adjust its installation positions on the first reference member 100 and the second reference member 200. The first reference member 100 includes a first rod portion 110 and a first reference portion 120 provided at the bottom of the first rod portion 110. The second reference member 200 includes a second rod portion 210 and a second reference portion 220 provided at the bottom of the second rod portion 210. The first rod portion 110 and the second rod portion 210 are symmetrically arranged. In this embodiment, the first reference portion 120 is a plane formed at the bottom of the first rod portion 110, and the second reference portion 220 is a plane formed at the bottom of the second rod portion 210.

[0033] The two ends of the connecting member 300 can be sleeved on the first rod portion 110 and the second rod portion 210 respectively in a slidable manner, and its installation positions on the first rod portion 110 and the second rod portion 210 are locked by a screw structure.

[0034] Embodiment 3: Refer to Figure 4 As shown, the difference between Embodiment 3 and Embodiment 2 is that the first reference portion 120 is an inclined plane formed at the bottom of the first rod portion 110 with an inclination angle of 30° to 45° (such as 35°), and the second reference portion 220 is an inclined plane formed at the bottom of the second rod portion 210 with an inclination angle of 30° to 45° (such as 35°). There is an inclination angle of 10° to 25° (such as 15°) between the plane where the leveling member 400 is located and the plane formed by the first reference member 100 and the second reference member 200.

[0035] Embodiment 4: Refer to Figure 5As shown, the difference between Embodiment 4 and Embodiment 2 or Embodiment 3 is that it includes a first leveling unit, a second leveling unit, and an extension unit. The first leveling unit includes a first reference member 100, a first connecting member 310 connecting the first reference member 100, and a first leveling member 410 arranged through the first connecting member 310. The second leveling unit includes a second reference member 200, a second connecting member 320 connecting the second reference member 200, and a second leveling member 420 arranged through the second connecting member 320. The extension unit includes an extension connecting member 330 and an extension leveling member 430 arranged through the extension connecting member 330. The first leveling unit, the extension unit, and the second leveling unit are spliced and connected in sequence. The splicing and connection method of the three can be to open threaded grooves at the same height positions of the first leveling member 410, the second leveling member 420, and the extension leveling member 430, and respectively pass bolts through the first leveling member 410, the extension leveling member 430, and the extension leveling member 430, the second leveling member 420 to fixedly connect the first leveling unit, the extension leveling unit, and the second leveling unit at one time. After splicing and connection, the first connecting member 310, the extension connecting member 330, and the second connecting member 320 form a connecting member 300, and the first leveling member 410, the extension leveling member 430, and the second leveling member 420 form a leveling member 400.

[0036] In some other embodiments, according to the width of the leveling area required in actual situations, the extension unit is made to include multiple ones, and the multiple extension units can be spliced and connected to each other in the same way.

[0037] Embodiment 5: Refer to Figure 6 As shown, the difference between Embodiment 5 and Embodiment 3 is that the first reference portion 120 includes a first sliding inclined surface, and the second reference portion 220 includes a second sliding inclined surface. The inclination degrees of the first sliding inclined surface and the second sliding inclined surface are the same as the inclination degree of the leveling member 400. In this embodiment, both the first sliding inclined surface and the second sliding inclined surface are inclined sliding moving surfaces composed of multiple rollers.

[0038] The leveling member 400 includes multiple leveling member monomers 400a. The leveling member monomers 400a close to the first reference member 100 are fixedly arranged on one side of the connecting member 300 in any form of existing technologies such as welding, screwing, gluing, etc.; the leveling member monomers 400a close to the second reference member 200 are movably arranged on the connecting member 300. For example, a collar is integrally formed on the top surface of the leveling monomer 400a on the side close to the second reference member 200, and the collar is sleeved on the other side of the connecting member 300; multiple leveling member monomers 400a between the aforementioned two leveling monomers 400a are hinged (such as a hinge structure) and connected. The connecting member 300 can be telescopic, such as a metal telescopic rod.

[0039] Thus, in this embodiment, the leveling member 400 is a foldable and retractable structure, and the connecting member 300 can be telescoped, facilitating storage and carrying.
