AI Technical Summary
In the traditional prefabricated kitchen and bathroom floor leveling process, surface concrete wet construction leads to a lot of construction waste, pollute the environment, and low leveling accuracy. Point leveling construction leads to excessive leveling thickness and high hollowness on the chassis floor.
The prefabricated kitchen and bathroom floor dry leveling process is adopted, and the leveling pad and filling layer are used to achieve accurate surface leveling. The chassis is on the leveling pad, and the filling layer is filled in the gap between the chassis and the structural floor slab. The position of the leveling pad is adjusted through infrared leveling. , the filling layer expands and cures to form surface-shaped automatic leveling, reducing the hollowness of the chassis, and ensuring the smoothness of the wall panel installation through the wall panel slot.
Accurate surface leveling is achieved, reducing construction waste and environmental pollution, rapid construction, thin leveling thickness, low hollowness on the chassis floor, and improved the accuracy and construction efficiency of leveling.

Abstract
Description
Technical Field
[0001] The present invention relates to a floor leveling process, and in particular to a dry leveling process for assembled kitchen and bathroom floors. Background Art
[0002] The floor leveling of prefabricated bathrooms and kitchens in traditional buildings mostly adopts wet surface concrete construction or point support leveling construction. The wet surface concrete construction produces a lot of construction waste, pollutes the environment, has low leveling accuracy, and is slow to construct. The point leveling construction results in extremely thick leveling thickness, and a high sense of hollowness in the chassis floor. Summary of the invention
[0003] The present invention aims to overcome the defects of the prior art and provide a prefabricated kitchen and bathroom floor dry leveling process for leveling the kitchen and bathroom floors of buildings, which can achieve precise surface leveling without the need for wet concrete construction, generate less construction waste, and maintain a clean environment. The construction is quick and convenient, and the leveling thickness is thin and the hollow feeling of the chassis floor is low.
[0004] The dry leveling process for assembled kitchen and bathroom floors described in the present invention includes a chassis, a leveling pad, a filling layer, and a structural floor; the characteristics are: the leveling pad is above the structural floor, the chassis is above the leveling pad, and the filling layer fills the gap between the bottom of the chassis and the structural floor; there are wall panel slots on the surface layer of the chassis; each chassis has at least 3 leveling pads at the bottom to support the bottom of the chassis, the tops of the leveling pads supporting the bottom of the chassis are in the same horizontal plane or close to the same horizontal plane, and the bottom of the chassis supporting the leveling pad is parallel or close to parallel to the bottom of the wall panel slot.
[0005] The dry leveling process for the assembled kitchen and bathroom floor is as follows: during leveling, leveling pads are placed at multiple points on the structural floor according to the required leveling thickness, and the thickness of each leveling pad is about 10 mm. When the leveling thickness is thick, each location can be stacked and placed, and every three or more leveling pads can support a chassis. An infrared level is used to irradiate the top of the leveling pad according to the required leveling thickness, so that the highest points of more than three leveling pads are on the same horizontal plane. The filling layer can be polyurethane foam, and then the filling layer is sprayed on the structural floor and the leveling pads where the leveled leveling pads are placed, and then the bottom of the chassis is placed on the top of the leveling pads and moved to position. Since the filling layer is fluid before solidification The foam is sprayed on the top of the hard leveling pad, which can play a lubricating role and facilitate the rapid movement and positioning of the chassis. The filling layer is sandwiched between the bottom of the chassis and the structural floor and continues to expand and solidify. The expansion, extrusion and solidification process of the filling layer forms a surface automatic dry leveling process for the installation chassis at the bottom of the chassis; the expansion, extrusion and solidification of the leveling pad and the filling layer between the bottom of the chassis and the structural floor can complement each other. The leveling pad can improve the rigid support performance of the filling layer. The solidified filling layer can make up for the insufficient surface support strength of the chassis supported by the point-shaped layout of the leveling pad, form a surface support, and make up for the problem of large hollow feeling of the chassis when the point-shaped leveling pad supports the chassis, thereby reducing the hollow feeling of the chassis. If leveling pads are used as the leveling base points, the entire chassis can be leveled. It is only necessary to support the highest points of several leveling pads at the bottom of the chassis as the leveling base points to make them in the same horizontal plane. Due to the error of the leveling measurement tool, it is generally impossible to achieve an absolutely identical horizontal plane. As long as it is close to the same horizontal plane (some leveling pads can be lower than the bottom of the chassis, and the gap formed by the leveling pads below the bottom of the chassis will also be squeezed and wrapped by the filling layer to form the same plane), the chassis supported by the leveling pads can be leveled. Point leveling does not require surface leveling, and there are fewer leveling base points, which is not prone to leveling. Flat deviation is convenient for accurate leveling; there are wall panel slots on the surface layer of the chassis, and the bottom of the chassis close to the leveling pad is parallel or nearly parallel to the bottom of the wall panel slot. In this structure, as long as the top of the leveling pad is leveled, the chassis and wall panel slots supported by the top of the leveling pad are also level, and the wall panels supported by the wall panel slots are also necessarily level and will not tilt left or right, which is convenient for quick leveling and calibration of the wall panels installed on the wall panel slots; further, each leveling pad is composed of multiple pieces stacked, and the thickness of each leveling pad is between 6mm and 15mm, thereby, thin leveling with a thickness of less than 15mm can be achieved.
[0006] In the dry leveling process for the assembled kitchen and bathroom floor, a floor drain is provided at the lower part of the chassis surface layer, and a drainage slope i is provided on the chassis surface layer which slopes toward the floor drain.
[0007] The dry leveling process for assembled kitchen and bathroom floors is characterized in that each leveling pad is stacked with multiple pieces, and the thickness of each leveling pad is between 6mm and 15mm.
[0008] In the dry ground leveling process of the present invention, the gap between two adjacent chassis is filled with a filling layer. BRIEF DESCRIPTION OF THE DRAWINGS
