Abstract

Disclosed are a ceramic tile leveling bracket, pushing and clamping pliers and a ceramic tile leveling and laying system. The ceramic tile leveling and laying system comprises: a ceramic tile leveling bracket (1), an insertion block (2) and pushing and clamping pliers (3), wherein the ceramic tile leveling bracket (1) is provided at the junction between two adjacent ceramic tiles (4), one end of the insertion block (2) is inserted into an insertion block through hole (16) of the ceramic tile leveling bracket (1), and the pushing and clamping pliers (3) push and clamp the insertion block (2) into the insertion block through hole (16), so that an insertion block bottom surface (21) is tangent to upper surfaces of the two ceramic tiles (4). The ceramic tile leveling and laying system is easy to operate, and helps to improve the laying efficiency and laying quality.

two or more serrations protruding from the insertion block top surface and arranged in the same straight line, wherein each serration comprises a vertical serration surface and an inclined serration surface, and the vertical serration surface is perpendicular to the insertion block bottom surface.

20. A ceramic tile leveling and laying system comprising:

a ceramic tile leveling bracket of claim 1, which is provided at the junction between two adjacent ceramic tiles;

an insertion block having one end inserted into an insertion block through hole of the ceramic tile leveling bracket; and

pushing and clamping pliers of claim 7, for pushing and clamping the insertion block to the insertion block through hole such that an insertion block bottom surface is tangent to upper surfaces of the two ceramic tiles.

7. Pushing and clamping pliers, comprising:

a first component, comprising a first clamping portion and a first handheld portion;

a second component, comprising a second clamping portion and a second handheld portion; and

a pivot via which the second clamping portion is rotatably connected to the first clamping portion;

characterized by further comprising;

a first clamping block disposed at a top end of the first clamping portion,

a second clamping block disposed at a top end of the second clamping portion and arranged opposite the first clamping block;

a clamping groove recessed from an inner side wall of the first clamping block, with the direction of an opening of the groove facing the second clamping block; and

a clamping through groove penetrating through the second clamping block and disposed opposite the clamping groove.

8. The pushing and clamping pliers of claim 7, characterized by further comprising:

a withdraw device for damaging the sheet of the ceramic tile leveling bracket to remove the portion of the insert above the sheet.

9. The pushing and clamping pliers of claim 8, characterized in that

the withdraw device comprises:
