Description

  The present invention relates to a tile peeling apparatus that peels off a tile attached to a wall surface of a structure.

Conventionally, an outer wall surface, an inner wall surface, a floor surface, and the like of a building have been finished with tiles.
When building a building with earthquake resistance or expansion / reconstruction, it is difficult to maintain the existing texture and color of new tiles, especially in the case of historically and culturally valuable buildings. It is also preferable to reuse existing tiles.
For that purpose, it is necessary to peel off the existing tile without damaging it.

Patent Document 1 describes a tile peeling tool.
As described in Patent Document 1, a conventional tile peeling tool peels off one side of a tile by applying a force in a direction parallel to a construction surface.

JP 2014-134092 A

However, the conventional tile peeling tool has the following problems.
(1) Since the direction in which the force is applied is the shearing direction with respect to the adhesive layer made of mortar on the back of the tile, the tile may be damaged without peeling depending on the shear strength of the mortar.
(2) Since a force is directly applied to the tile, the tile may be damaged.

  An object of this invention is to provide the tile peeling apparatus which can peel a tile without damaging it.

The first invention of the present application made to achieve the above object includes an upper clamp, a lower clamp opposite to the upper clamp, an upper clamp blade extending from the upper clamp, and extending from the lower clamp, A lower clamp blade portion that faces the upper clamp blade portion, a pivot bolt that is rotatably provided on the upper clamp and that is inserted into the lower clamp, and a screw that is provided on the lower clamp and is screwed onto the pivot bolt. A flat lever that extends horizontally from the upper clamp and the lower clamp, the upper clamp blade and the lower clamp blade. Provided is a tile peeling device comprising a shaped gripping part and a blade part that is inclined to face the gripping part.
According to a second invention of the present application, in the tile peeling device according to the first invention, a lower nut that is screwed into the screwed portion and screwed into the rotating bolt that is inserted into the lower clamp, and an extrapolated to the rotating bolt. And an elastic body disposed between the lower nut and the lower clamp.
A third invention of the present application provides the tile peeling device according to the first or second invention, wherein the tile peeling device has a handle provided on the upper clamp.

The present invention can obtain at least one of the following effects by means for solving the above-described problems.
(1) Since the clamp blade portion has a blade portion that penetrates the adhesive layer, the tile can be easily peeled off without damaging the tile by applying a force in the tensile direction to the adhesive layer.
(2) Since the force is applied to the adhesive layer through the blade portion while the tile is held by the holding portions of the upper and lower clamp blade portions, the force is not applied to the tile and is not damaged.
(3) Since the force is applied to the blade portion and peeled in a state where the tile is held by the flat holding portion, the tile force does not act and break.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[1] Tile peeling device <1> Overall configuration The tile peeling device of the present invention is for peeling a tile from a wall surface while sandwiching and holding the tile from above and below.
The tile peeling device includes an upper clamp 1 and a lower clamp 2 for sandwiching a tile from above and below, a rotating bolt 3 for moving the lower clamp 2 up and down relative to the upper clamp 1, and a rotating lever 4 for rotating the rotating bolt 3. And the handle 5 (FIG. 1).

<2> Upper Clamp and Lower Clamp The upper clamp 1 and the lower clamp 2 have a flat plate shape and face each other with a predetermined interval.
The upper clamp 1 and the lower clamp 2 are provided by extending an upper clamp blade portion 11 and a lower clamp blade portion 21 from corresponding one sides, respectively.
The upper clamp blade portion 11 includes a grip portion 111 that extends horizontally from the upper clamp 1 and a blade portion 112 that is inclined downward from the tip of the grip portion 111.
The lower clamp blade portion 21 has a symmetrical shape with the upper clamp blade portion 11, and includes a gripping portion 211 that extends horizontally from the lower clamp 2, and a blade portion 212 that is inclined upward from the tip of the gripping portion 211. Become. Each blade part 112,212 opposes.
The width of the upper clamp blade portion 11 and the lower clamp blade portion 21 is preferably substantially the same as the width of the tile to be peeled off.
The upper clamp blade part 11 and the lower clamp blade part 21 are fixed to the upper clamp 1 and the lower clamp 2 through fixing means such as bolts. The fixing means may be provided with means for adjusting the extending lengths of the upper clamp blade portion 11 and the lower clamp blade portion 21.
The upper clamp blade 11 and the lower clamp blade 21 may be formed integrally with the upper clamp 1 and the lower clamp 2.

<3> Rotating bolt At the center of the upper clamp 1, the rotating bolt 3 is rotatably attached via a bearing or the like, and at the center of the lower clamp 2 is a screwing portion 22 that is screwed to the rotating bolt 3. Provide. The screwing portion 22 may be formed directly on the lower clamp 2, or another member may be fixed to the lower clamp 2.
The rotating bolt 3 passes through the lower clamp 2 by being screwed into the screwing portion 22.
A lower nut 31 is fixed to the penetrating rotation bolt 3.
Between the lower clamp 2 and the lower nut 31, an elastic body 32 made of a spring or the like externally attached to the rotating bolt 3 is disposed.

<4> Rotating lever A rotating lever 4 for turning the rotating bolt 3 is attached to the head of the rotating bolt 3.
The rotation lever 4 has a mechanism for limiting the rotation direction of the rotation bolt 3 such as a ratchet mechanism.

<5> Open / Close State The rotation bolt 3 is rotatably attached to the upper clamp 1. Then, the rotating bolt 3 is screwed into a screwing portion 22 provided in the lower clamp 2.
Accordingly, when the rotating bolt 3 is rotated, the lower clamp 2 moves up and down along the rotating bolt 3. Since the upper clamp 1 does not move at this time, the upper clamp 1 and the lower clamp 2 are opened and closed, and the interval can be adjusted by rotating the rotating bolt 3 (FIG. 2).
When the support 12 is erected on the left and right of the rotating bolt 3 on the lower surface of the upper clamp 1 and the support bearing 23 corresponding to the support 12 is provided in the lower clamp 2, the upper clamp 1 and the lower clamp 2 are opened and closed in a parallel state. Can be maintained.

  In the case where the rotating lever 4 has a ratchet mechanism, rotation occurs when the rotational load of the rotating bolt 3 becomes too small. However, the elastic force of the elastic body 32 disposed between the lower clamp 2 and the lower nut 31 is reduced. It acts on the lower nut 31 fixed to the rotating bolt 3 and becomes a rotational load of the rotating bolt 3, thereby preventing the occurrence of rotation.

<6> Handle A handle 5 for holding the tile peeling device with one hand is attached to the upper clamp 1.

[2] Tile Peeling Method Next, a tile peeling method using the tile peeling device of the present invention will be described.

<1> Grooving Grooves 71 are formed on the upper and lower joints of the tile 6 to be peeled by a cutter or the like (FIG. 3a).
The width of the groove 71 is made wider than the upper and lower widths of the blade portions 112 and 122 of the upper clamp blade portion 11 and the lower clamp blade portion 21.
The depth of the groove 71 is made deeper than the back surface of the tile 6 to be peeled off.
The groove 71 is preferably formed at a position where it does not contact the tile 6.

<2> Insertion of clamp blade portion The upper clamp blade portion 11 and the lower clamp blade portion 21 are inserted in the grooves 71 formed in the upper and lower joints of the tile 6 (FIG. 3b).
The upper clamp blade portion 11 and the lower clamp blade portion 21 are fixed to the upper clamp 1 and the lower clamp 2 through fixing means such as bolts, and the extended lengths of the upper clamp blade portion 11 and the lower clamp blade portion 21 are fixed to the fixing means. When means for adjusting the height is provided, the extension length is adjusted in accordance with the depth of the groove 71 and the thickness of the tile 6, and the insertion positions of the upper clamp blade portion 11 and the lower clamp blade portion 21 are adjusted. can do.

<3> Grabing of the tile The rotation lever 4 is rotated to narrow the distance between the upper clamp 1 and the lower clamp 2, and the blade portions 112, 212 of the upper clamp blade portion 11 and the lower clamp blade portion 21 are moved to the rear surface of the tile. The adhesive layer 7 is penetrated (FIG. 3c).
Since the tile peeling device can be held with one hand if the handle 5 is held, the turning lever 4 can be turned easily.
Since the tile peeling device is positioned so as to contact the wall surface W to which the tile 6 is attached, the rotation range of the rotation lever 4 is limited to a substantially semicircular range with respect to the wall surface W. 4 has a mechanism for restricting the rotation direction of the rotating bolt 3, so that the rotating bolt 3 can be easily rotated even in a reciprocating motion within a substantially semicircular range.
When the groove 71 is formed at a position not in contact with the tile 6, the joint adhesive layer 7 exists between the upper surface of the tile 6 and the upper clamp blade portion 11 and between the lower surface of the tile 6 and the lower clamp blade portion 21. At this time, the tile 6 and the adhesive layer 7 are gripped by the upper clamp blade portion 11, the lower clamp blade portion 21, and the planar grip portions 111 and 211.
The tile 6 can also be directly held by the gripping portions 111 and 211 without using the adhesive layer 7.

<4> Lifting of rotating lever When the rotating lever 4 is lifted upward in a state where the tile 6 is gripped by the upper and lower clamping blade portions 11, 21, the lower clamp is performed using the blade portion 112 of the upper clamping blade portion 11 as a fulcrum. A force acts on the blade 212 of the blade 21 (FIG. 3d).
Since the tile 6 and the adhesive layer 7 are gripped by the upper clamp blade portion 11, the lower clamp blade portion 21, and the planar grip portions 111 and 211, the force acts only on the tile 6 and the tile 6 is damaged. There is nothing.
Even when the tile 6 is directly clamped, it is clamped by the planar gripping portions 111 and 211, and the force acts on the blade 212, so that the tile 6 is not damaged.
Since the turning lever 4 has a length of the handle portion, even if it is pulled up with a small force, the force acting on the blade portion 212 of the lower clamp blade portion 21 is increased by the lever principle.
When the rotation lever 4 is tilted upward, the force acting on the lower clamp blade portion 21 is in the direction away from the wall surface W, and is in the tension direction with respect to the adhesive layer 7 of the tile 6. Since the mortar that is a general adhesive layer 7 has low tensile strength, the adhesive layer 7 and the tile 6 can be easily peeled from the wall surface W.

<5> Peeling of tiles When the rotation lever 4 is further tilted, the peeling of the adhesive layer 7 reaches the upper clamp blade part 11, and the tile 6 can be completely peeled from the wall surface W (FIG. 3e).
Even when completely peeled off, the tile 6 is held between the upper clamp blade portion 11 and the lower clamp blade portion 21, and the tile 6 does not fall and break.
The tile 6 thus peeled can be easily detached from the tile peeling device by rotating the turning lever 4 to widen the interval between the upper clamp blade portion 11 and the lower clamp blade portion 21.
