Description

  The present invention relates to an adhesive peeling device for peeling off an adhesive remaining on a casing wall surface when a wall panel is dismantled in renewal work or the like.

A GL method is known as one of the straight-line methods for attaching a wall panel to a frame wall.
In the GL method, an interior wall is constructed by spotting a gypsum-like gypsum-based adhesive (GL bond) on the wall surface of the housing and pressing a wall panel made of gypsum board over it (FIG. 8). .

When disassembling interior walls constructed by the GL method in seismic reinforcement work or renewal work, wall panels made of gypsum board can be easily dismantled, but the dotted adhesive remains on the walls of the frame. End up.
This adhesive is hardened and must be scraped off with a hammer drill or scraped with a disc grinder to be removed.

The removal of the cured adhesive has the following problems.
(1) A hammering sound or vibration is generated when a hammer drill or scraper is used.
(2) The work that generates impact noise and vibration is limited in work time, particularly in seismic reinforcement work and renewal work, so the construction period is prolonged.
(3) When the hammer drills off or the disc grinder scrapes off, a force acts in the direction of the wall surface of the housing, which may damage the housing wall surface.
(4) The hardened adhesive is scraped off and scraped off, which is a heavy labor and a heavy burden on the workers.

  An object of this invention is to provide the adhesive peeling apparatus which can peel the adhesive hardened | cured easily, without generating a noise.

The first invention of the present application made to achieve the above object includes a horizontally long main body, a fixed blade unit provided on the front surface of the main body near one end in the length direction, and a length direction of the main body.

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

<1> Adhesive Peeling Device The adhesive peeling device 1 of the present invention includes a main body 2, a fixed blade unit 3 that is fixed to the surface near one end of the main body 2, and a rail material that is disposed along the surface of the main body 2. 4. It consists of the moving blade unit 5 which slides on the rail material 4, and the sliding unit 6 which slides the moving blade unit 5 (FIG. 1).

<2> Main Body The main body 2 is a horizontally long member formed by combining a plurality of aluminum frames, for example.
On the front surface of the main body 2, the fixed blade unit 3 is fixed in the vicinity of one end, and the rail material 4 is disposed from the fixed blade unit 3 to the other end.
The main body 2 is provided with a sliding unit 6 for sliding the movable blade 5 sliding on the rail material 4 so as not to interfere with the fixed blade unit 3 and the rail material 4.
A handle 7 is provided on the back surface of the main body 2.

<3> Fixed Blade Unit The fixed blade unit 3 includes a plate-shaped fixed blade 31 disposed along the main body 2 and a fixed blade base 32 that holds the fixed blade 31 at a predetermined interval from the front surface of the main body 2. .
The fixed blade 31 is formed on one side with a fixed penetrating blade 311 projecting at an acute angle with the cutting blade as the main body 2 side, and the cutting blade of the fixed penetrating blade 311 is disposed toward the moving blade unit 5 with the main body 2 side.
The fixed penetrating blade 311 may be formed using a cemented carbide tip 311a (FIG. 2).

<4> Rail Material The rail material 4 is a linear guide for sliding the slide block 41 along the front surface of the main body 2.
One or a plurality of rail members 4 are arranged in the lateral direction of the front surface of the main body 2.

<5> Moving Blade Unit The moving blade unit 5 includes a plate-shaped moving blade 51 disposed along the main body 2 and a moving blade base 52 that holds the moving blade 51 at a predetermined interval from the front surface of the main body 2. .
By moving the movable blade base 52 to the slide block 41, the movable blade unit 5 slides on the rail material 4.
The movable blade 51 is formed on one side with a movable penetrating blade 511 that protrudes at an acute angle with the cutting blade as the main body 2 side, and is disposed toward the fixed blade unit 3.
The movable penetrating blade 511 may be formed using a cemented carbide tip 511a (FIG. 2).

<6> Sliding Unit The sliding unit 6 is a hydraulic cylinder having a cylinder 61 and a rod 62. In addition to the hydraulic cylinder, it may be anything that linearly moves the movable blade unit 5, such as an air cylinder, an electric cylinder, a ball screw, or a linear motor.
The sliding unit 6 fixes the cylinder 61 to the front surface of the main body 2 and fixes the tip of the rod 62 to the moving blade base 52 of the moving blade unit 5.
Since the cylinder 61 is fixed to the main body 2, the movable blade unit 5 attached to the tip of the rod 62 slides on the rail member 4 by expanding and contracting the rod 62. Since the rail material 4 and the slide block 41 are linear guides, no noise is generated during sliding.

<7> Combination of Fixed Blade and Moving Blade The fixed blade 31 and the moving blade 51 face the fixed penetrating blade 311 and the moving penetrating blade 511, and are arranged at an equal distance from the front surface of the main body 2 (FIGS. 3 and 4).
The fixed blade 31 and the movable blade 51 are both plate-shaped, and are formed in an eight-character shape that opens in the direction of the main body 2 so that the fixed penetrating blade 311 and the movable penetrating blade 511 are separated from the front surface of the main body 2. And tilt it.
Since the movable blade unit 5 slides on the rail material 4, the movable blade 51 moves along the main body 2.
Then, the movable blade unit 5 is slid to bring the movable blade 51 closer to the fixed blade 31, so that the fixed blade 31 and the movable blade 51 are separated with an adhesive interposed therebetween.
The distance between the moving blade 51 and the fixed blade 31 when the moving blade unit 5 is slid to bring the moving blade 51 closest to the fixed blade 31 can be adjusted by the arrangement of the rail material 4 and the sliding unit 6. If this interval is small, the performance of peeling off the adhesive is high, but if the interval is increased to create a gap C as shown in FIG. 4, something other than the adhesive is accidentally placed between the fixed blade 31 and the moving blade 51. Accidents can be prevented.

<8> Peeling Method Next, an adhesive peeling method using the adhesive peeling device 1 will be described.

<8.1> Arrangement of Adhesive Peeling Device When the interior wall constructed by the GL method is disassembled, the cured adhesive (GL bond) B remains on the surface of the casing wall surface W.
The adhesive peeling device 1 extends the sliding unit 6 so that the fixed blade 31 and the movable blade 51 are opened at least wider than the width of the adhesive B, and the adhesive B is sandwiched between the fixed blade 31 and the movable blade 51. To the wall surface W of the housing (FIG. 5).

<8.2> Peeling of Adhesive When the fixed blade 31 and the moving blade 51 are aligned with the housing wall surface W, the sliding unit 6 is operated to slide the moving blade unit 5 along the rail material 4.
When the distance between the fixed penetrating blade 311 and the movable penetrating blade 511 is smaller than the width of the adhesive surface of the adhesive B to the housing wall surface W, the adhesive B is applied between the fixed blade 31 and the movable blade 51 by the contraction force of the sliding unit 6. The fixed penetrating blade 311 and the moving penetrating blade 511 are inserted between the adhesive B and the casing wall surface W or into the adhesive B (FIG. 6).
Since the fixed blade 31 and the movable blade 51 are eight-shaped in the direction of closing with respect to the casing wall surface W, the adhesive B can be sandwiched along the casing wall surface W.
When the sliding unit 6 is further contracted, the cured and integrated adhesive B is integrated even if there is a gap C between the fixed penetrating blade 311 and the moving penetrating blade 511. It peels from the housing wall surface W (FIG. 7).
Since the movable blade 51 slides in parallel along the casing wall surface W, no force acts on the casing wall surface W, and there is no possibility of damaging the casing wall surface.

Since the movable blade 51 of the movable blade unit 5 is slid by the linear guide, no noise or vibration such as a hitting sound is generated. For this reason, work time is not limited even in earthquake-proof reinforcement work and renewal work, and construction can be performed in a short construction period.
Moreover, since the adhesive B can be peeled only by sliding the movable blade 51 with the sliding unit 6, it can be performed by anyone without any burden on the operator.

  In the above-described embodiments, the GL bond is exemplified as the adhesive B. However, the present invention is not limited to the GL bond, and it is possible to peel a material that is dotted on the surface of the skeleton, such as mortar and unreinforced concrete.
