Description

Overhead floor assembly and mounting method

Technical Field

The invention relates to the technical field of decoration design, in particular to an overhead floor assembly and an installation method.

Background

The current decoration industry is developing towards the direction of industrialized modularized installation, generally speaking, floor decoration is a decoration method commonly adopted in indoor design, and can increase the layering sense of indoor space and play a role in beautifying decoration.

The fabricated floor structure has a raised floor system, and various surface layers such as tiles, floors, carpets and the like are laid on the raised floor system. When a base layer is laid, the ground needs to be raised, the network floor needs to be raised by using adjusting feet, and meanwhile, the function of conveniently adjusting the height is achieved, but the installation and the leveling of the conventional raised floor are always realized by adjusting the raised height of the floor under the floor, so that the raised ground is leveled, for example, chinese patent utility model CN204510721U discloses a raised floor structure, the upper surface of a single raised floor is provided with a groove arranged along the edge, and four corners of the bottom surface are provided with supporting holes for inserting and connecting adjusting supports; the adjusting support comprises a threaded base and a support seat in threaded connection with the top of the threaded base, the support seat is inserted into the support hole in a matched mode, and the edge of the bottom of the support seat protrudes in a step shape and is clamped on the bottom surface of the single raised floor outside the support hole; gaps at the centers of the four single raised floors are covered by the cross-shaped floors, the edges of the cross-shaped floors are lapped on the grooves at the centers and are clamped by the clamping strips, the gaps between the adjacent single raised floors are covered by the side floor, and the edges of the side floor are lapped on the grooves at the centers and are clamped by the clamping strips. The floor of the utility model is erected on the ground by the adjusting support, and the line can be laid in the gap between the floor and the ground, so as to keep the indoor beauty; the height of the adjusting support is adjustable, so that the height and the flatness of the raised floor can be adjusted, the line operation is faster and more convenient, and the operation cost and the operation process are reduced.

However, the above-described raised floor structure still has the following problems: the structure is complicated, can't follow the upside forward regulation after the installation, when needs adjust the floor, still need dismantle the floor, need carry out the built on stilts altitude mixture control on floor at the downside on floor to carry out the leveling to built on stilts ground, so the floor can lead to the piece between the floor great when needing the dismouting, still probably leaks between this piece and seeps water, leads to whole waterproof performance poor.
