Description

Technical Field

[0001] The utility model relates to the technical field of assembled decoration, in particular to an assembled metal keel dry method floor. Background Art

[0002] The traditional approach to interior floor decoration is to use wet work. The basic steps are: design, line marking, laying plain concrete, leveling, laying tiles or wooden floors and other finishing materials. The disadvantage of this method is that it is a wet work, requires a lot of cement and sand, has a poor working environment, has many construction steps, a long construction period, a large floor load, and is prone to hollowing and cracking during use, which does not meet the requirements of energy conservation and environmental protection.

[0003] The current domestic prefabricated floor systems include the following:

[0004] (1) GRC point-supported assembled floor: It consists of metal adjustable feet, fixing screws, GRC base board and decorative surface layer;

[0005] (2) As disclosed in patent CN2022200917608, the nylon adjustable foot assembled floor consists of nylon adjustable feet, base board, floor heating module, overhead leveling layer and decorative surface layer;

[0006] (3) Metal base assembled floor as disclosed in patent CN2021207176522: It consists of metal adjustable feet, base metal base, balance layer and decorative surface layer;

[0007] (4) As disclosed in patent CN2021231730519, the assembled floor is composed of metal adjustable feet, base plate, etc.

[0008] There are still some problems in the construction process of the above-mentioned prefabricated floor. For example, in (1) and (2), when installing the floor, it is necessary to first lay out the lines on site according to the designed position of the support feet and mark the position of the support feet, which makes the construction more complicated. In (1), (2) and (3), the floor adjustment feet cannot be locked after leveling, which may cause unevenness due to collision when installing the base plate. In (1) and (2), the floor cannot be adjusted on the plate, and the base plate needs to be disassembled for secondary adjustment, which is very inconvenient to install. In (3) and (4), the floor needs to use a mechanical fixing method to fix the metal support feet on the metal base or base plate, and due to the large number of metal support feet, it takes a long time to complete this process, which is not conducive to improving construction efficiency. In (3), the metal base of the floor cannot be cut on site, and the GRC base plate in the GRC point-supported prefabricated floor is not easy to cut. Both have the limitation of small tolerance range. In (1) and (2), the floor support feet provide point support for the four corners of the base module, and the stability of the floor is poor.

[0009] To sum up: the current existing prefabricated floor construction has the following problems: the existing prefabricated floor has the process of needing to lay out lines to locate and install support feet or mechanically fix the metal support feet, the construction process is relatively complicated and the construction efficiency is low; there is a problem of inconvenience in leveling or inability to fix after leveling; there is a problem of small product tolerance and the need for customized processing; there is a problem of small support area and poor ground stability.
