Abstract

A tile leveling structure includes a plate body and an extension member. The plate body has an accommodation space. One part of the extension member is received, limited, and fixed in the accommodation space, and the other part thereof is extended from the accommodation space downwardly to pass through the plate body. When in operation, the plate body is turned/rotated and an adjusting block is pushed toward the extension member so that a first extension part (and a second extension part) of the extension member is guided into an elongated slot of the adjusting block by a V-shaped open end of the adjusting block. Due to a bottom end of the first L-shaped extension part (and the second L-shaped extension part) and the limitation between a stopping end of the plate body and the upper inclined surface of the adjusting block, the two adjacent tiles may be leveled by a lower surface which is flat of the adjusting block. It is easy to operate and assembly. And further, it may be reused by reversing the operation step so as to achieve the effects of cost reduction and environmental protection.

Description

Auxiliary structure for tile leveling

The invention relates to a construction-related field, in particular to a tile-leveling auxiliary structure.

According to the press, the currently known tile leveler is composed of a T-shaped seat and a supporting seat, and the T-shaped seat is provided with a bottom plate including a front side plate and a rear side plate, and is connected with a handle part and a The vertical piece of the part and a perforated part, wherein the front side plate and the rear side plate have a plurality of cylindrical ribs, and the center of the front side plate and the rear side plate are respectively recessed inwardly with a notch; by the support seat passing through the perforated part, and After a downward force is exerted on the tile by the supporting seat, the flatness between the top and bottom surfaces of each tile can be adjusted.

However, the front plate and rear plate area of the T-seat base plate of the aforementioned conventional tile leveler is too large, resulting in the problem of difficult construction. That is, when it is in the actual construction state, the two tiles and The gap between the front and back panels cannot be filled evenly with cement glue and tile adhesive, so that the tile and cement cannot be easily and firmly bonded, resulting in the collapse of the stressed end of the tile and the non-stressed end lifting up The situation can not achieve the effect of tile leveling at all.

An object of the present invention is to provide a tile leveling auxiliary structure. During operation, the plate is rotated and then the adjustment block is pushed forward, so that the first extension portion (and the second extension portion) of the extension member uses a V-shaped The open end is led into its long groove, and then the bottom end of the L-shaped first extension (and the bottom end of the L-shaped second extension) and the upper end of the plate body and the adjustment block are inclined Mutually resisting the limit effect makes the lower surface of the adjustment block level the adjacent two tiles at the same time, which is not only easy to operate and easy to assemble, but also can be recovered in reverse operation steps after the tile is completed. Use to achieve cost reduction and environmental protection.
