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.

First claim

The invention claimed is:

1. A ceramic tile leveling and laying system comprising:
a ceramic tile leveling bracket, which is provided at a junction between two adjacent ceramic tiles;
an insertion block having one end inserted into the ceramic tile leveling bracket; and
pushing and clamping pliers, being configured to push the insertion block into the ceramic tile leveling bracket so that the insertion block is clamped to the ceramic tile leveling bracket;
wherein the ceramic tile leveling bracket comprises:
a pad for supporting bottom surfaces of the two adjacent ceramic tiles;
an insert protruding from an upper surface of the pad, for being inserted into a gap between the two adjacent ceramic tiles; and
a breakable sheet located at a lower portion of the insert and adjacent to the pad;
wherein the insert comprises:
a hole which penetrates the insert and into which the insertion block is inserted;
a bayonet disposed on a side edge of the insert on one or either side, and the bayonet having a height from the pad which is greater than a height of the sheet from the pad; wherein the bayonet is configured to be engaged by a withdraw tool to remove an upper part of the insert; and
a hook-shaped engagement block disposed on a side edge of the insert on one or either side and the hook-shaped engagement block protruding toward the bayonet;
wherein a bottom of the bayonet is arc-shaped, and a portion of the bayonet that is close to the hook-shaped engagement block forms a hook-shaped bayonet portion;

wherein the pushing and clamping pliers comprises:
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 that 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 a 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;
wherein the clamping-through groove is aligned with the clamping groove in an opening and closing direction of the pushing and clamping pliers when the pushing and clamping pliers are closed.

2. The ceramic tile leveling and laying system of claim 1 , wherein the insert further comprises:
a linear groove recessed from a surface of the insert on one or either side, a bottom of the linear groove being the sheet.

3. The ceramic tile leveling and laying system of claim 1 , wherein a bottom surface of the pad is an arc-shaped surface, which is part of a cylindrical side surface; and
two ends of the pad extend upward from a middle of the bottom surface to make contact with the bottom surfaces of the ceramic tiles.

4. The ceramic tile leveling and laying system of claim 3 , wherein the pad comprises:
the two ends of the pad are provided to a reinforcing rib respectively, which is used to make contact with and support the bottom surfaces of the ceramic tiles.

5. The ceramic tile leveling and laying system of claim 1 , wherein the pad comprises at least one pad through hole which penetrates the pad along a thickness direction of the pad.

6. The ceramic tile leveling and laying system of claim 1 , wherein a longitudinal section of the insertion block is wedge-shaped, wherein a lower end of the insertion block is configured to insert into the ceramic tile leveling bracket, and a higher end of the insertion block is configured to match with the pushing and clamping pliers, so that the pushing and clamping pliers can push and clamp the insertion block to the ceramic tile leveling bracket.

7. The ceramic tile leveling and laying system of claim 6 , wherein the insertion block comprises:
an insertion block bottom surface, which is a plane;
an insertion block top surface, which is an inclined plane and forms an acute angle with the insertion block bottom surface.

8. The ceramic tile leveling and laying system of claim 7 , wherein the insertion block further comprises two or more serrations protruding from the insertion block top surface.

9. The ceramic tile leveling and laying system of claim 8 , wherein the two or more serrations are arranged in the same straight line.

10. The ceramic tile leveling and laying system of claim 8 , wherein each of the two or more serrations comprises a vertical serration surface and an inclined serration surface, and the vertical serration surface is perpendicular to the insertion block bottom surface.

11. The ceramic tile leveling and laying system of claim 1 , wherein the pushing and clamping pliers further comprises:
a withdraw device for damaging the sheet of the ceramic tile leveling bracket to remove the portion of the insert above the sheet.

12. The ceramic tile leveling and laying system of claim 11 , wherein the withdraw device comprises:
a hook angled portion protruding in a barb shape from an outer side wall of the first clamping block; and
a rounded portion disposed at a joint between a side wall and the top of the second clamping block; or
the withdraw device comprises:
a hook angled portion protruding in a barb shape from an outer side wall of the second clamping block; and
a rounded portion disposed at a joint between a side wall and the top of the first clamping block;
wherein the withdraw device is configured such that: the hook angled portion is engaged into the ceramic tile leveling bracket and the rounded portion is in contact with a surface of a ceramic tile as a fulcrum.

13. The ceramic tile leveling and laying system of claim 1 , wherein the pushing and clamping pliers further comprising:
an elastic member having one end connected to the first clamping portion and another end connected to the second clamping portion.

14. The ceramic tile leveling and laying system of claim 1 , wherein the pushing and clamping pliers further comprising:
