Marble threshold telescopic device

Abstract

The invention discloses a marble threshold telescopic device comprising a terrace, floor tiles and floors. The floor tiles are laid on one side of the upper surface of the terrace, and the floors arelaid on the other side of the terrace. A cement layer is arranged between the floor tiles and the terrace, the floors and the terrace are supported through keels, and two pieces of marble are laid between the floor tiles and the floors. A cement layer is arranged between the marble and the terrace, and the pieces of marble are overlaid. According to the marble threshold telescopic device, on the one hand, the telescopic function of a marble threshold can be achieved, and on the other hand, the transition problem of the solid wood floors and the floor tiles can be completely solved; and the overall structure is simple, design is reasonable, and the manufacturing and using cost is low.

Description

technical field [0001] The invention relates to the technical field of marble thresholds, in particular to a marble threshold extension device. Background technique [0002] At present, most of the existing lifting threshold devices use reverse design such as telescopic opening and closing doors to reversely realize the lifting function of the threshold. Extend out a threshold at the back, form a closed space with this and realize that equipment passes through the entrance and exit door smoothly. But the disadvantage of this structure is that it is not very convenient to use, and there are strict requirements on the telescopic state of the telescopic door when the door is opened and closed, and no mistakes can be made; At the same time, the existing marble threshold cannot realize the transition problem between the solid wood floor and the floor tiles, thereby affecting the use. To solve these problems, therefore, we propose a marble threshold extension device. Contents ...
