Description

  The present invention is a tile porcelain peeling suitable for peeling off and removing a surface material such as tile porcelain or stone plate stuck to a concrete surface using an adhesive, for example, a mortar containing a synthetic resin. The present invention relates to a tool horizontal cutter and a tile ceramic stripping tool.

Conventionally, at least a tile ceramic piece from a concrete surface such as a tile surface obtained by adhering a surface material such as a tile ceramic piece or stone plate to a concrete such as a building by interposing an adhesive such as a mortar containing synthetic resin. In the removal of tiles for peeling and repairing, it is common to perform edge cutting with a concrete cutter at the joint between a healthy tile and an unhealthy tile, and then use an air chipper or electric chipper to crush the unhealthy tile. there were. When removing tiles with a chisel, even a healthy tile that should not be delaminated due to the large vibrations generated during the chiseling is peeled off, and the tile is destroyed by directly removing the tile and reused in the building. It was impossible and uneconomical. Also, the chisel gives excessive vibrations to the body of the operator, such as orthopedic diseases such as tendonitis in the wrist and elbow, and respiratory diseases by inhaling dust scattered when the tiles are peeled off. There was a risk of causing health damage, and further, vibration and noise were transmitted to the entire building, and the chisels in the occupancy state caused great mental pain for the residents.
In view of the drawbacks of conventional chipping work, as a tile porcelain stripping tool, an insertion piece provided with a blade at the tip at one end of the connecting shaft that is narrower than the joint width of the tile is approximately the center of the connecting shaft. Mounted at an angle of 90 degrees, and a strut is continuously provided at the other end of the connecting shaft, and a striking piece that is substantially parallel to the insertion piece at an angle of approximately 90 degrees with the support is provided on the connecting shaft side of the support shaft. What has been proposed is proposed. And insert the tip of the insert piece of the tile porcelain stripping tool from the part where the joints have been partially removed in advance, lift the mortar for attachment slightly at the tip of the insert piece, and the bottom surface of the attachment mortar (the mortar for attachment and the concrete surface) Insert the insertion piece into the boundary part), and rotate the connecting shaft 90 degrees in the circumferential direction under this insertion condition, rotate the insertion piece 90 degrees, and between the mortar for bonding and the concrete surface It has been proposed to secure a continuous gap between the pasting mortar and the concrete surface so as to form a peeling gap (see, for example, Patent Document 1).
In the invention disclosed in Patent Document 1, as shown in FIG. 3, the insertion piece inserted between the tile ceramic piece and the concrete surface is rotated 90 degrees in one direction (see the arrow in FIG. 3). In order to float the mortar for attachment by moving the insertion piece, the range in which the insertion piece can be peeled when moving a single straight line is only on one side with the base of the connecting shaft as the center. When peeling work is also performed in the opposite direction around the connection axis, the insertion piece must be translated in one direction around the connection axis and rotated 180 degrees. There was a problem that work was not possible and work efficiency was poor.
A doughnut-shaped rotary blade and fan are pivotally attached to the rotary shaft of the disc grinder in the cover with a dust bag, and the rotary blade exposed from the bottom of the cover rotates in the circumferential direction and the periphery of the rotary blade makes sliding contact with the part to be cut. A cutter used for cutting concrete and tiles that cuts the part to be cut and collects the dust generated during cutting in the dust bag by the air flow generated by the rotation of the rotary blade and fan. Has been proposed (see, for example, Patent Document 2).
The invention disclosed in Patent Document 2 is capable of cutting an object to be ground such as concrete or tile ceramic pieces in the thickness direction, but the blade keeps the horizontal state in the horizontal direction and does not rotate, so the concrete surface It is impossible to use it for peeling off surface materials such as castings attached to the surface. Therefore, it cannot be applied to peeling and removing tile ceramic pieces stuck to the concrete surface of the present application using a mortar for sticking or the like from the concrete surface.
In Patent Document 3, a cutting blade is formed by electrodepositing abrasive grains having different diameters alternately in the circumferential direction in a substantially equal range on the outer peripheral end face of a disc-shaped substrate having a tightening portion opened at the center. From the abrasive grains of different diameters disclosed is a casting cutting cutter in which abrasive regions are scattered in all exposed portions except for the cutting edge and the clamping portion of the substrate and geometrically arranged on both sides as shown in FIG. Since the main abrasive grains and the secondary abrasive grains are alternately provided in the circumferential direction, a difference occurs in the acting stress applied to the particles of the primary abrasive grains and the secondary abrasive grains, the initial sharpness is good, and the work load is For the abrasive region of the geometric arrangement scattered on the substrate, inexpensive abrasive particles were used so that the substrate and the workpiece do not contact during rotation.
The cutter disclosed in Patent Document 3 also cuts the casting in the thickness direction, and does not assume that the casting adhered to the flat surface is peeled off.

On the plane side of the horizontal cutter body 2, an abrasive film 11 is also deposited on the vicinity of the base portion of the shaft portion 3. An abrasive film 12 is deposited on the entire peripheral surface of the shaft 3 continuously with the abrasive film 11. The abrasive coatings 10, 11, and 12 are formed by depositing hard abrasive grains by electrodeposition. As the abrasive, it is preferable to appropriately use any of diamond particles, cubic boron nitride particles, or particles obtained by mixing diamond particles and hard oxide particles. The particle size is not critical, but is preferably about 30 to 80 mesh. It is to be noted that the present invention includes that the abrasive coatings 10, 11, and 12 are made of diamond-like carbon (DLC) and deposited on the deposition surface using a chemical vapor deposition method (CVD method) or the like.

A tool receiving portion 25 is installed between the upper edge of the front side wall 15 and the upper edge of the rear side wall 16, a cushion member 26 is interposed on the upper end surface of the tool receiving portion 25, and the rear end portion of the tool 27 is attached to the presser fitting 28. And fix it. The upper end of the bending clamp 29 is fastened with a tightening bolt 30 in a screw groove recessed in the tool 27, and the lower end of the bending clamp 29 is fixed with a tightening bolt 32 screwed into the bolt hole 31. Below the suction port 20, the bottom surface of the horizontal cutter body 2 is disposed in parallel with the bottom surface 14. The horizontal cutter body 2 is disposed below the front portion of the suction port 20 in the traveling direction, and the peripheral edge of the horizontal cutter body 2 is positioned in front of the front edge of the suction port 20. In the present invention, the peripheral edge of the horizontal cutter body 2 is not limited to be positioned in front of the front edge of the suction port 20. Dust generated by the rotation of the horizontal cutter 1 comes out from the joint 33. Since the dust that has come out of the joint 33 is sucked in the opening portion of the suction port 20 that is behind the arrangement portion of the horizontal cutter body 2, the dust is completely collected by the dust collector and is not scattered around. The rotary drive shaft mounting shaft 4 is inserted so that the hole 24 is loosely inserted, and is connected so that the rotary drive shaft 8 and the axis of the tool 27 are located on the same straight line. The discharge port 22 is connected in airtight communication with the tip of a suction hose 23 of a dust collector (not shown) provided separately.

The operation of the tile ceramic piece peeling tool and the horizontal cutter will be described.
A core-extracted portion in which the horizontal cutter main body 2 is inserted with a tool such as an ultrasonic core around one intersection of the vertical joint 33 and the horizontal joint 33 in the pasting range of the unhealthy tile ceramic pieces 34 in advance. Drilling). The tile ceramic pieces 34 and the adhesive that are partially damaged around the intersection are removed with a grinder with a dust collector, and the exposed surface is finished to a smooth surface. All the joints 33 in the range where the unhealthy tile ceramic pieces 34 are attached are cut with a cutter. As shown in FIG. 12, the horizontal cutter body 2 with the gripping portion 18 in one hand and the tool 27 in the other hand so that the bottom surface of the horizontal cutter body 2 abuts the exposed surface at the core removal portion. The tile ceramic piece peeling tool is arranged so that the shaft portion 3 is located at the joint 33. At the same time, the dust collector (not shown) of the suction hose 23 connected to the discharge port 22 is driven. When the tool 27 is driven and the rotary drive shaft 8 rotates, the shaft portion 3 also rotates in synchronization with the rotary drive shaft 8 and the horizontal cutter body 2 also rotates in the circumferential direction. As shown in FIG. 13, when the tile ceramic piece peeling tool is moved while the bottom surface 14 is in sliding contact with the surface of the tile ceramic piece 34 so that the shaft part 3 passes through the joint 33, the abrasive coating 12 of the rotating shaft part 3 is moved. 14 is cut in the joint 33 that remains on the side edges of the unhealthy tile ceramic piece 34 and proceeds in one direction, and the abrasive coating 10 of the rotating cutting blade 5 and the rotating horizontal cutter body 2 are rotated as shown in FIG. The adhesive 35 made of mortar containing synthetic resin is peeled off from the surface of the concrete 36 with the abrasive coating 11 around the shaft base, and as a result, the unhealthy tile ceramic pieces 34 together with the adhesive 35 are replaced with the concrete 36. Peel from the surface. Further, the horizontal cutter body 2 enters between the concrete 36 and the adhesive 35 and proceeds in one direction while rotating at a high speed. Therefore, the horizontal cutter body 2 has the radius of the horizontal cutter body 2 in the traveling direction around the shaft portion 3. The sticking agent 35 and unhealthy tile ceramic pieces 34 are peeled off from the surface of the concrete 36. On the other hand, the dust derived from the adhesive 35 generated by the rotation of the horizontal cutter body 2 is sent from the chip discharge groove 6 to the suction port 20 through the plane of the horizontal cutter body 2 by the suction force of the dust collector, and instantly. Dust is collected in the dust collector. Since the suction port 20 is opened in a remarkably long rectangular shape along the traveling direction, the dust from the joint 33 after passing through the horizontal cutter body 2 generated by the rotational movement of the horizontal cutter body 2 is removed from the suction port 20. Suction is done behind the horizontal cutter body 2 and no dust is scattered.

The tile porcelain stripping tool is a shaft portion that rotates by sliding the bottom portion of the horizontal cutter body 2 against the concrete surface and moving the shaft portion 3 through the joint 33 while sliding the bottom surface 14 on the surface of the tile porcelain 34. The joint material remaining on the side edge of the tile porcelain is cut with the abrasive coating to remove the path obstructions of the shaft portion 3 to enable a dramatic improvement in work efficiency, and it is necessary to peel off without generating vibration. Only the tile ceramic pieces 34 and the adhesive 35 can be peeled off from the surface of the concrete 36, and there is an effect that it is possible not to peel off a healthy portion that does not require peeling. Since the horizontal cutter body 2 rotates along the surface of the concrete 36, the sticking agent 35 can be peeled in a planar shape, and perfect and quick peeling and removal can be performed without the sticking agent 35 remaining on the concrete 36. There is an effect that efficiency can be improved.
There is an effect that the two rows of tile ceramic pieces disposed on both sides of the joint 33 through which the shaft portion 3 of the horizontal cutter 1 passes can be peeled off by passing the shaft portion 3 once.
There will be no situation where even a healthy tile ceramic piece sticking part that does not need to be peeled is peeled off. New tile ceramic pieces with different colors will be used in part, and existing healthy tile ceramic pieces will be reused. There is an economic effect that can be.
Dust that has come out of the joints is sucked into the chip discharge pipe from the back of the horizontal cutter body out of the suction port of the chip discharge pipe by driving the dust collector, and is collected in the dust collector. There is an effect that dust does not scatter around. Since the suction port is opened in a rectangular shape that is remarkably long in the left-right direction, which is the direction of travel, dust coming out of the joint is sucked behind the horizontal cutter body 2 in the suction port and can be instantly collected completely. effective.

A second embodiment will be described with reference to FIGS. The tile ceramic piece peeling tool includes a horizontal cutter 37, a tool mount 38 and a tool 39.
First, the horizontal cutter 37 will be described with reference to FIGS. The horizontal cutter 37 includes a horizontal cutter body 40, a shaft portion 41, and a rotation drive shaft mounting shaft 42. In the horizontal cutter body 40, cutting edges 43 and chip discharge grooves 44 that are recessed radially inward are arranged alternately at regular intervals along the circumferential direction. Steps are provided at the opening edges of the cutting blade 43 and the chip discharge groove 44. Specifically, a chip discharge groove 44 is provided on the circumference of a small-diameter circle of the concentric circles at equal intervals and recessed in a U shape radially inward, and a small diameter is provided between adjacent chip discharge grooves 44, 44. A cutting edge 43 is provided on the circumference of a large-diameter circle having a step and a circumference of the circle and the outer end surface being concentric. In other words, the outer edge surface of the cutting blade 43 is disposed on the circumference of the large diameter circle with a step and a circumference of the small diameter circle. That is, the chip discharge groove 44 is opened in a small diameter circle among the concentric circles, and the outer end surface of the cutting blade 43 is disposed in the large diameter circle among the concentric circles. An abrasive film (not shown) is formed on the cutting blade 43 including the blade tip surface. In the second embodiment, the case where the abrasive film is deposited on the cutting edge 43 has been described as an example. However, depending on the material of the cutting edge 43, it is not always necessary to form the abrasive film, and the abrasive film is formed. Cutting blades 43 that are not included are also included in the present invention.

  Coatings 45 and 46 made of diamond particles are deposited on the flat and bottom surfaces of the horizontal cutter body 40 with a uniform layer thickness. The reason why the coatings 45 and 46 made of diamond particles are deposited is that diamond has a large thermal conductivity, and the frictional heat generated by friction with the adhesive such as mortar during rotation of the horizontal cutter 37 causes the horizontal cutter body 40 to This is to prevent the temperature from rising.
