Description

  The present invention relates to a peeling method using a peeling device for peeling a cement hardened material applied to a predetermined portion of a structure from the structure.

  In buildings, finishing is carried out by constructing a mortar with a predetermined thickness on the surface of the concrete frame. However, it is necessary to renovate the mortar after a period of time and to increase the thickness of the walls and ceiling. In this case, the mortar applied to the surface of the concrete frame is removed prior to new finishing work or thickening. Conventionally, mortar peeling work has been done by dismantling the existing mortar by the operator directly using a small rock drill or hammer drill. However, the chiseling machines such as small rock drills and hammer drills destroy the mortar by sending compressed air from the compressor and applying vibration and hammering to the mortar. There was a problem of being bad. In particular, if the building to be constructed has a 24-hour business system or is a hospital or school where quietness is required, the working hours will be greatly limited due to the noise associated with the peeling work. A long time was required to complete the work, and problems such as high labor costs for the peeling work occurred.

  In the case of these hammering / vibration-type chipping machines, the hammering and vibration are also transmitted to the housing, so that there is a risk that damage such as cracks may be induced in the housing. In addition, in seismic reinforcement work, it is necessary to completely remove low-strength mortar and expose only the concrete frame. However, it takes a long time to peel off the mortar evenly with these chiseling machines that perform chiseling locally. There was a problem that the mortar could not be peeled off with high accuracy. Furthermore, when these chiseling machines are used, there is a problem that the disassembled mortar becomes a fine crushed piece, a lot of dust and dust are generated, and the working environment is deteriorated.

  In order to solve the above problems, the following mortar peeling method has been proposed (see Patent Document 1). This mortar peeling method is intended for a mortar finished surface in which mortar is constructed with a specified thickness on the surface of the concrete frame. Bring a disk-shaped concrete cutter held on the rotating shaft, and turn the rotating shaft to the concrete surface. The mortar is cut and separated by inserting a concrete cutter at the boundary between the concrete frame and the mortar while moving the concrete cutter parallel to the surface of the concrete frame while being held orthogonally. This method has an effect that the mortar constructed on the surface of the concrete frame can be disassembled in a short construction period with low noise.

JP 2001-81975 A

  Since the mortar peeling method disclosed in Patent Document 1 moves the cutter while rotating the concrete cutter to cut the mortar, the cutting surface of the mortar and the blade edge of the cutter rub against each other to generate a large cutting sound. Although it is possible to suppress the noise generated compared to the case where the chipping operation is performed by the chipping machine, it is difficult to bring the sound generated in the peeling operation close to an acceptable quiet sound. Also, in this mortar peeling method, a wedge-shaped chip piece is installed on the periphery of the concrete cutter, and the mortar is cut by the rotation of the wedge-shaped chip piece as the concrete cutter rotates. The peeling force is difficult to concentrate, and a large peeling force cannot be transmitted to the mortar. In the case of a mortar that is firmly applied, the mortar may not be smoothly peeled off.

  An object of the present invention is to provide a peeling method that can make an acceptable quiet sound generated during a peeling operation and can smoothly peel a hardened cement from a structure.

  As another example of the present invention, in the peeling method, the sound pressure level generated when the hardened cement material is peeled is in the range of 40 to 80 dB.

  Another example of the present invention is a hydraulic jack in which a jack is connected to an electric hydraulic pump.

  According to the peeling method of the present invention, the piston rod is gradually extended forward in one direction while the first connecting shaft enters the first through hole and the second connecting shaft retracts from the first through hole. (2) The connecting member is gradually moved forward in one direction along the guide member, thereby peeling the cement hardened material having a predetermined thickness from the structure using the cutter while gradually moving the cutter forward in one direction forward ( Therefore, there is no generation of a large cutting sound due to friction between the cutting surface of the hardened cement and the cutter, and the sound generated during the peeling operation can be made an acceptable quiet sound. In the peeling method, the cylinder is gradually moved forward in one direction while the second connecting shaft enters the first through hole and the first connecting shaft is withdrawn from the first through hole, and the first connecting member is used as a guide member. Accordingly, the jack can be returned to the state at the time of the initial movement of the peeling operation (the state in which the piston rod is accommodated in the cylinder), and the peeling operation can be started again from this state. In the peeling method, force (torque) is transmitted linearly from the piston rod of the jack to the cutter, and the straight running force of the cutter can be concentrated at the peeling site of the hardened cement material, so that a large peeling force is applied to the hardened cement material. Since it acts, even if it is the hardened cement hardened | cured material, the hardened | cured material can be peeled smoothly and reliably. The peeling method can smoothly peel the hardened cement from the structure by using a jack. Therefore, not only can the work of peeling the hardened cement be completed efficiently in a short period of time, but also the structure. From the above, the hardened cement can be peeled over a wide range at a time, and the peeling work can be performed at a low cost. In the peeling method, unnecessary vibration is not transmitted to the structure when the hardened cement is peeled off. Therefore, the hardened cement can be peeled while maintaining the state of the structure without damaging the structure. Further, the hardened cement can be uniformly peeled from the structure in a short time with high accuracy, and the peeling work can be performed in a favorable environment with less dust and dust generation.

  By performing the first movement process, the first advance / retreat process, the second movement process, and the second advance / retreat process, the peeling work for each time is completed, and the structure is constructed by performing these processes a plurality of times. The peeling method that can peel all of the cemented product from the peeling start position to the peeling end position is repeated multiple times by repeating the first movement process, first advance / retreat process, second move process, and second advance / retreat process. The peeling operation can be repeated, and even if the peeled length of the hardened cement is long, all the hardened cement to be peeled can be peeled from the structure.

  Before carrying out the first first moving step, a guide groove creating step is carried out, in which two guide grooves extending straight in one direction along the outer edge of the peeling width are formed on the outer surface of the cement hardened material. Fixing the cemented material at the location between the two and carrying out the cutter installation hole creation process to drill the cutter installation hole to install the cutter at that location, and the device fixing process to install and fix the peeling device at the location between the guide grooves Since the guide groove is formed in the outer edge of the cement hardened product peeling width by the guide groove creation process, and the peeling device is installed and fixed inside these guide grooves, the guide groove is carried out. It is possible to peel only the hardened cement that exists on the inside of the structure, and it is possible to partially peel the hardened cement from the structure. It can be. Peeling method is to make a cutter installation hole with a predetermined depth to install the cutter in the place between guide grooves by cutter installation hole creation process, then install the cutter into the cutter installation hole with a predetermined depth and peel the cement hardened material By doing so, the hardened cement material having a predetermined thickness can be reliably peeled off from the structure. As for the peeling method, it is possible to perform the peeling work of the hardened cement by simply fixing the peeling device at the peeling point, and it is possible to greatly shorten the work period for peeling the hardened cemented material and to make the peeling work inexpensive. It can be carried out.

  With the first connecting shaft entering the first through hole and the second connecting shaft withdrawing from the first through hole, the piston rod is gradually advanced into the cylinder and the second connecting member is moved in one direction along the guide member. After moving the second connecting member gradually backward, the second connecting member is moved backward in one direction, and then the second connecting shaft enters the first through hole and the first connecting shaft is withdrawn from the first through hole. In the third advancing / retreating step, the piston rod is gradually exposed from the inside of the cylinder and the first connecting member is guided while the second connecting shaft enters the first through hole and the first connecting shaft is withdrawn from the first through hole. A fourth moving step of gradually moving backward in one direction along the member; and, after moving the first connecting member backward in one direction, causing the first connecting shaft to enter the first through hole. The peeling method for carrying out the fourth advancing / retreating step of retracting the second connecting shaft from the first through hole is a third moving step of moving the jack and the first and second connecting members moved forward in one direction along the guide member.・ Since the 3rd advance / retreat process, 4th move process, 4th advance / retreat process, the jack and the first and second connecting members can be moved back in one direction. The state of being housed in (1) can be returned to, and the peeling operation can be started again from that state.

  By performing the third movement step, the third advance / retreat step, the fourth move step, and the fourth advance / retreat step a plurality of times, the jack and the first and second connection members are moved from the cemented cured product peeling end position to the peeling start position. The peeling method that can be returned is that the guide member is released from the peeling position by releasing the fixation of the guide member in a state where the jack and the first and second connecting members are returned to the peeling start position. Is installed at the other exfoliation site of the building, and the first moving process, first advance / retreat process, second move process, and second advance / retreat process are performed, so that the cement hardened material at the site where the exfoliation device is newly installed Peeling can be performed.

  After the last fourth advance / retreat step is performed and the peeling device is returned to the cement start material peeling start position, the device fixing release step of removing the peeling device from the peeled portion of the cement hardened material is performed with a jack and a first With the first and second connecting members returned to the peeling start position, the guide member can be released and the guide member can be removed from the peeling site, and the removed guide member can be used as another peeling site in the building. By installing and performing the first movement process, the first advance / retreat process, the second movement process, and the second advance / retreat process, it is possible to peel the cement hardened material at the place where the peeling device is newly installed.

  The peeling device includes first and second moving mechanisms that move the first and second connecting members in one direction along the guide member, and the moving mechanism is attached to the guide member and extends in one direction. The peeling method formed from the first and second sliders attached to the first and second connecting members and slidably engaged with the slide rail is such that the first and second connecting members are guided members via the moving mechanism. The cemented material having a predetermined thickness is surely peeled off from the structure by the first movement process, the first advance / retreat process, the second move process, and the second advance / retreat process. (Peeling). In addition, the third moving process, the third advancing / retreating process, the fourth moving process, and the fourth advancing / retreating process performed thereby can return the jack moved forward in one direction to the rear in one direction, It is possible to return to the initial movement state.

  The first connecting member is formed of a first mounting seat, a pair of first and second guide plates, and a first advancing / retracting mechanism, and the second connecting member is a second mounting seat, a pair of third and fourth guide plates, A second through hole formed from the second advancing / retracting mechanism and capable of inserting and removing the first connecting shaft that has entered the first through hole is formed in the first and second guide plates, and the second through hole that has entered the second through hole. In the peeling method in which the third through hole in which the connecting shaft can be inserted and removed is formed in the third and fourth guide plates, the first connecting shaft that has entered the first through hole is the second through hole of the first and second guide plates. By entering the hole, the first connecting member is securely fixed to the guide member, and in this state, the piston rod can be gradually extended forward in one direction, thereby causing the cutter to gradually advance forward in one direction. Use a cutter to harden the cement to a certain thickness from the structure. It can be reliably peeled off taking (peeled). In the peeling method, the second connecting shaft that has entered the first through hole enters the third through hole of the third and fourth guide plates, so that the second connecting member is securely fixed to the guide member. The jack can be returned backward in one direction, whereby the jack can be returned to the state at the time of the initial movement of the peeling operation.

  A cutter is formed by a cutter that is positioned forward in one direction of the second mounting seat and is formed of a blade edge that is located at a predetermined depth from the outer surface of the hardened cement and a base that is connected to the blade mouth and is attached to the second mounting seat. In the peeling method in which the movement of the cutter in the direction away from the outer surface of the hardened cement material is prevented, the piston rod gradually extends forward in one direction while maintaining the biting state of the blade edge with respect to the hardened cement material by the fixing means. As a result, the blade edge of the cutter gradually advances forward in one direction, so that the hardened cement with a predetermined thickness can be reliably peeled off (peeled) from the structure by the blade edge. The peeling device does not generate a large cutting sound due to the cutting surface of the hardened cement and the cutter rubbing against the blade edge, and can make the sound generated during the peeling operation an acceptable quiet sound.

  A first light emitting unit that irradiates the first light toward the second guide plate is installed on the first guide plate, and a first light receiving unit that receives the light emitted from the first light emitting unit is installed on the second guide plate. The second light emitting unit that emits the second light toward the fourth guide plate is installed on the third guide plate, and the second light receiving unit that receives the light emitted from the second light emitting unit is the fourth guide plate. When the first light emitted from the first light emitting unit passes through the first through hole and enters the first light receiving unit, the first connecting shaft faces the first through hole so that it can be inserted and removed. When the second light emitted from the second light emitting portion passes through the first through hole and enters the second light receiving portion, the second connecting shaft is detachably opposed to the first through hole. The method is such that when the first light emitted from the first light emitting part of the first photosensor enters the first light receiving part, the first connecting shaft faces the first through hole. Since the first optical sensor is attached to the first connecting member as described above, the first coupling shaft can be surely entered into the first through hole by the signal from the first optical sensor, and the second optical sensor When the second light emitted from the second light emitting part is incident on the second light receiving part, the second photosensor is attached to the second connecting member so that the second connecting shaft faces the second through hole. Therefore, the second connecting shaft can surely enter the second through hole by the signal from the second optical sensor.

  After the first light emitted from the first light emitting part passes through the first through hole and enters the first light receiving part, 0.1 to 1.0 seconds later, the first connecting member moves in one direction. Stopping the movement and allowing the first connecting shaft to enter the first through hole, the second light emitted from the second light emitting part passes through the second through hole and enters the second light receiving part. For example, the peeling method that stops the movement of the second connecting member in one direction and allows the second connecting shaft to enter the first through hole after the elapse of 0.1 to 1.0 second from Immediately after the first light emitted from the light emitting part passes through the first through hole and enters the first light receiving part, the movement of the first connecting member in one direction is stopped and the first connecting shaft first is stopped. Immediately after the second light emitted from the second light emitting part passes through the second through hole and enters the second light receiving part, the second contact is made. When the movement of the member in one direction is stopped to allow the second connecting shaft to enter the first through hole, the axial center of the first through hole and the axial centers of the first and second connecting shafts May not match, and the first and second connecting shafts may not be allowed to enter the first through hole. However, after the first and second lights are incident on the first and second light receiving parts, 0. After 1 to 1.0 seconds have elapsed, the first and second connecting members are stopped to allow the first and second connecting shafts to enter the first through holes. By adjusting the time during which entry is possible in the range, the axial center of the first through hole and the axial center of the first and second connecting shafts in accordance with the movement of the first and second connecting members in one direction And the first and second connecting shafts can be securely inserted into the first through hole. Rukoto can.

  By setting the first number of incidences of the second light irradiated from the second light emitting part and passing through the first through-hole to the second light receiving part, one-way forward of the second connecting member in the first moving step The second movement can be adjusted by setting the second number of incidences of the first light irradiated from the first light emitting part and passing through the first through hole and entering the first light receiving part. The peeling method capable of adjusting the moving dimension of the first connecting member in one direction forward in the process is such that the number of times the second light sensor conducts gradually in the process of moving the second connecting member forward in one direction. Although it increases, by setting (adjusting) the number of times of conduction (the number of first incidents), the movement dimension of the second connecting member in one direction forward in the first movement step (the extension dimension of the piston rod in one direction forward) ) Can be adjusted, so it can be It is possible to adjust the peeling length of the peeled to cement cured product. In the peeling device, the number of times of the first light conduction in the first optical sensor gradually increases in the process of moving the first connecting member forward in one direction, but the number of times of conduction (second incidence number) is set (adjusted). By doing so, it is possible to adjust the moving dimension of the first connecting member forward in one direction in the second moving step (extension dimension of the cylinder forward in one direction). The peeling operation can be started again from this state.

  By setting the third number of times of incidence of the second light irradiated from the second light emitting part and passing through the first through hole into the second light receiving part, one direction rearward of the second connecting member in the third moving step The fourth movement can be achieved by setting the fourth number of incidences of the first light that has been irradiated from the first light emitting part and passed through the first through-hole to be incident on the first light receiving part. In the process, the peeling method capable of adjusting the movement dimension of the first connecting member in one direction rearward is a process in which the first and second photosensors move in the first and second photosensors in the process of moving the first and second connecting members backward in one direction. The conduction number of the second light gradually increases. By setting (adjusting) the conduction number (third and fourth incidence times), the second connection member moves backward in one direction in the third movement step. Adjust the dimension (extended dimension of piston rod in one direction rearward direction) And the movement dimension of the first connection member in one direction rearward in the fourth movement step (extension dimension of the cylinder in the rearward direction of one cylinder) can be adjusted, so that the jack and the first and second connection members Can be reliably returned to the peeling start position. In the peeling method, with the jack and the first and second connecting members returned to the peeling start position, the guide member is released, the guide member is removed, and the removed guide member is removed to another peeling location of the building. When the first moving process, the first advancing / retreating process, the second moving process, and the second advancing / retreating process are carried out and the cemented material is peeled off at that location.

  By setting the fifth number of incidences of the second light that has been irradiated from the second light emitting unit and passed through the first through-hole, the number of times of incidence is set to the second light receiving unit, from the peeling start position to the peeling end position of the cemented material The moving dimension of the second connection member corresponding to the total peeling dimension in one direction can be set, and is incident on the first light receiving part of the first light irradiated from the first light emitting part and passing through the first through hole. By setting the sixth incidence number to be, the peeling device capable of setting the moving dimension forward in one direction of the first connecting member corresponding to the total peeling dimension from the peeling start position to the peeling end position of the hardened cement product, By setting the fifth and sixth incidence times, the first and second connecting members move forward in one direction corresponding to the total peel dimension in one direction from the peel start position to the peel end position of the cement cured product. Can be set in the peeling device. From the peeling start position to the peeling end position, the first moving process, the first advance / retreat process, the second movement process, and the second advance / retreat process are continuously repeated, and the cemented material is peeled continuously. All of the hardened cement in one direction can be peeled at a time.

  By setting the seventh number of incidences of the second light that has been irradiated from the second light emitting unit and passed through the first through hole, the number of times of incidence is set, so that the cement hardened material can be peeled from the peeling end position to the peeling start position. The moving dimension of the second connecting member in one direction rearward corresponding to the total peeling dimension can be set, and is incident on the first light receiving part of the first light irradiated from the first light emitting part and passed through the first through hole. By setting the number of times of the 8th incident, the peeling method capable of setting the movement dimension of the first connecting member in one direction rearward corresponding to the total peeling dimension from the peeling end position to the peeling start position of the cement cured product is By setting the seventh and eighth incidence times, the first and second connecting members move backward in one direction corresponding to the total peel dimension in one direction from the peel end position to the peel start position of the hardened cement material. Can be set in the peeling device. The third moving process, the third advancing / retreating process, the fourth moving process, and the fourth advancing / retreating process are continuously repeated, and the first and second connecting members that have reached the peeling end position are moved from the peeling end position to the peeling start position. You can return it at once.

  A first gear that is rotated by driving the first motor and a first pinion that is driven by the rotation of the first gear; and a second gear that is rotated by the driving of the second motor. The peeling method formed from the second pinion that advances and retreats by the rotation of the second gear allows the first connecting shaft to advance and retreat to the first through hole by rotating the first gear, and the rotation of the second gear. By doing so, the second connecting shaft can be advanced and retracted into and from the first through hole, so that the first advancing and retracting process and the second advancing and retracting process can be smoothly performed, and the third advancing and retracting process and the fourth advancing and retracting process can be smoothly performed. Can be implemented.

  By adjusting the width dimension in the direction intersecting with one direction of the cutter blade edge, the peeling method capable of adjusting the peel dimension in the direction intersecting with one direction of the hardened cement peeled from the structure is the cutter edge. By reducing the width dimension of the cement, it is possible to reduce the peel dimension of the cement cured product that peels from the structure. By increasing the width dimension of the cutter blade edge, the cement cured product that peels from the structure is peeled off. Since a dimension can be enlarged, it can respond to the peeling dimension (peeling area) of the cement hardened | cured material which peels from a structure, and can peel a cement hardened | cured material from a structure only by a desired peeling dimension.

  It is a hollow metal tube with a square cross section extending in one direction and having a length dimension equal to or greater than the peel length of the hardened cement from which the guide member peels, and is equal to or greater than the peel length of the hardened cement from which the slide rail peels. The stripping method, which is a metal rod with a square cross section extending in one direction with a length dimension of, is the stripping length of the hardened cement that peels from the structure by changing the length dimension of the guide member and slide rail Therefore, it is possible to cope with the peel length of the hardened cement material peeled from the structure, and to peel the hardened cement material from the structure by a desired length. In the peeling method, the guide member of a predetermined length dimension fixed by the fixing means prevents the cutter from moving in a direction away from the outer surface of the cement hardened material, so that the cutter can surely bite into the cement hardened material. The cement cured product having a predetermined thickness can be reliably peeled from the structure.

  The peeling method in which the hardened cement is a mortar or grout of a certain thickness applied to the concrete frame of the structure, and the peeling device peels the mortar or grout from the concrete frame, the jack rod of the jack gradually extends forward in one direction. As the cutter gradually advances forward in one direction, the cutter peels off the mortar or grout of a predetermined thickness from the concrete housing (peeling off), and from the concrete housing without generating a loud sound. Mortar and grout can be peeled off. In the peeling method, force (torque) is transmitted linearly from the piston rod of the jack to the cutter (blade), and the straight running force of the cutter can be concentrated on the mortar or grout peeling area, so that it can be applied to the mortar and grout. Since a large peeling force acts, even a mortar or grout that is firmly constructed can be peeled off smoothly and reliably. As for the peeling method, mortar and grout can be smoothly peeled off from the concrete frame by using a jack, so that not only can the stripping work be completed efficiently in a short period of time, but also vibration that is unnecessary for the concrete frame. Can not be transmitted, so mortar and grout can be peeled off without damaging the concrete frame. In addition, mortar and grout can be uniformly peeled from the concrete frame in a short period of time with high accuracy, so that dust and dust are not generated in the peeling work, and the peeling work can be performed in a favorable environment.

  In the peeling method in which the sound pressure level generated at the time of peeling of the hardened cement is in the range of 40 to 80 dB, since the sound pressure level generated at the time of peeling is in the above range, the hardened cement from the structure without generating a large noise. The sound generated during the peeling operation can be made an acceptable quiet sound. As for the peeling method, the cemented product can be peeled from the structure made in a place where a quiet environment is required. Peeling of the hardened cement can be completed.

  The peeling method, in which the jack is a hydraulic jack connected to an electric hydraulic pump, can transmit a large force (torque) from the piston rod to the cutter (blade) by using it as a jack that operates hydraulically. Since a large peeling force acts on the hardened cement material, the hardened cement material can be smoothly and reliably peeled from the structure.

  The peeling method uses the peeling apparatus 10 which peels the mortar (cement hardened | cured material) constructed on the outer surface of the concrete frame of a structure, and implements various processes mentioned later. Structures include all buildings such as office buildings, intelligent buildings, housing complexes, hospitals, schools, nuclear power plants, indoor parking lots, underground parking lots, etc., and all types of structures such as dams, bridges, roads, and outer walls. Constructs are included. The peeling apparatus 10 can be used not only for peeling mortar but also for peeling concrete and grout. Therefore, the peeling method is not used only for peeling mortar but also for peeling concrete or grout.

  The peeling device 10 used for the peeling method includes a guide member 11, a fixing means 12 (see the drawing) for fixing the guide member 11 to a structure, a hydraulic jack 13, a first connection member 14, a second connection member 15, and a first movement. A mechanism 16, a second moving mechanism 17, a cutter 18, a first optical sensor 19, a second optical sensor 20, and a controller 90 are provided.

  The guide member 11 is a hollow metal tube (an iron tube, an aluminum tube, a stainless steel tube, or the like) extending in one direction, and its cross-sectional shape is formed into a quadrangle. The guide member 11 includes a top wall 21 and a bottom wall 22 that face in the longitudinal direction and extend in one direction, and both side walls 23 and 24 that face in the width direction and extend in one direction. The guide member 11 may have a cross-sectional shape that is not limited to a quadrangle, but may be a circle. The guide member 11 is installed at a separation location of the building so as to be spaced apart from the outer surface of the mortar by a predetermined dimension and in parallel with the outer surface of the mortar. The guide member 11 only needs to have a length dimension equal to or greater than the peeling length of the mortar to be peeled, and the length dimension is not particularly limited.

  The side walls 23 and 24 of the guide member 11 are perforated with a plurality of first through holes 25 that penetrate the side walls 23 and 24 in the width direction and are arranged at equal intervals in one direction.

The first mounting seat 30 has a top wall 34 extending in the width direction, both side walls 35 extending in the vertical direction, and a front wall 36 extending in the vertical direction.

  The first mounting seat 30 is firmly fixed to a connecting jig 37 whose front wall 36 extends from the rear end portion of the hydraulic cylinder 26 via a predetermined fixing means. As a fixing means for fixing the front wall 36 of the first mounting seat 30 and the connecting jig 37 of the hydraulic cylinder 26, for example, when the connecting jig 37 of the cylinder 26 is welded to the front wall 36 of the first mounting seat 30. Alternatively, a male screw is formed on the connecting jig 37 of the cylinder 26, a female screw is formed on the front wall 36 of the first mounting seat 30, and the connecting jig 37 is screwed on the front wall 36 and the connecting jig. A nut may be screwed onto the 37 male screw. The first connecting member 14 is connected to the cylinder 26 (hydraulic jack 13) by fixing the front wall 36 of the first mounting seat 30 to the connecting jig 37 of the hydraulic cylinder 26.

  The first guide plate 31 is connected to one side wall 35 of the first mounting seat 30, is located on the outer side in the width direction of the side wall 23 of the guide member 11, and extends straight in the vertical direction. The second guide plate 32 is connected to the other side wall 35 of the first mounting seat 30, is located on the outer side in the width direction of the side wall 24 of the guide member 11, and extends straight in the vertical direction. The first plan plywood 31 and the second guide plate 32 are formed with second through holes 38 that penetrate the plates 31 and 32 in the width direction.

The first gear 41 is housed inside the first housing 39 and is rotatably attached to the rotation shaft of the first motor 40. The first gear 41 rotates in the clockwise direction or the counterclockwise direction by driving the first motor 40 (rotation of the rotation shaft). Most of the first pinion 42 (first connection shaft 29) is accommodated in the housing 39 in a state of being advanced toward the first housing 39. A male screw (pinion gear) is formed on the peripheral surface of the first pinion 42, and the male screw (pinion gear) is engaged with the first gear 41 (rack gear). The first pinion 42 can advance and retreat in the width direction by the rotation of the first gear 41.

As shown, it moves in the width direction toward the first and second through holes 25 and 38. As the first gear 41 rotates in the direction indicated by the arrow L1, the first pinion 42 enters the second through hole 38, passes through the second through hole 38, and then enters the first through hole 25. Then, after passing through the first through hole 25, it enters the second through hole 38 (see FIG. 5). When the first pinion 42 enters the first and second through holes 25, 38, the rotation of the first gear 41 in the direction indicated by the arrow L 1 stops and the first connection via the first connection shaft 29. The movement of the member 14 in one direction becomes impossible.

  The first pinion 42 (the first connecting shaft 29) is exposed from the first housing 39 and substantially half of the first pinion 42 (the first connecting shaft 29) enters the first and second through holes 25, 38. When it rotates in the direction shown by the arrow L3, it moves in the width direction toward the housing 39 as shown by the arrow L4. As the first gear 41 rotates in the direction indicated by the arrow L 3, the first pinion 42 exits from the second through hole 38, exits from the first through hole 25, and exits from the second through hole 38. The first housing 39 is accommodated. When the first pinion 42 is withdrawn from the first and second through holes 25 and 38 and enters the inside of the first housing 39, the rotation of the first gear 41 in the direction indicated by the arrow L3 is stopped, The first connecting member 14 can be moved in one direction.

As a fixing means for fixing the second casing 58 to the second mounting seat 50, when one side wall of the casing 58 is welded to the third guide plate 51 or the side wall 55 of the mounting seat 50, In some cases, female screws are formed on the side wall, the third guide plate 51, and the side wall 55 of the mounting seat 50, and bolts are screwed to the female screws and nuts are screwed to the bolts. A cable 62 (electric wire and interface) connected to the power source via the controller 90 extends below the second housing 58.

  The second motor 59 is disposed outside the second housing 58 and is fixed to the housing 58 via fixing means (not shown). The rotation axis of the second motor 59 is exposed inside the second housing 58. Electricity is supplied to the second motor 59 from the cable 62, and the rotation shaft rotates in the clockwise direction or the counterclockwise direction by the conduction of the electricity. The second gear 60 is housed inside the second housing 58 and is rotatably attached to the rotation shaft of the second motor 59. The second gear 60 rotates clockwise or counterclockwise by driving the second motor 59 (rotating shaft). Most of the second pinion 61 (second connection shaft 49) is accommodated in the housing 58 in a state of being advanced toward the second housing 58. A male screw (pinion gear) is formed on the peripheral surface of the second pinion 58, and the male screw (pinion gear) is engaged with the second gear 60 (rack gear). The second pinion 58 can advance and retract in the width direction by the rotation of the second gear 60.

FIG. 12 is a side view of the apparatus 10 showing an example of a peeling method (peeling procedure) of the mortar 72 using the peeling apparatus 10. is there. FIG. 13 is a front view of the peeling apparatus 10 in the state of FIG. 12, and FIG. 14 is a side view of the peeling apparatus 10 showing a peeling method continued from FIG. FIG. 15 is a front view of the peeling apparatus 10 in the state of FIG. 11 to 15, the vertical direction (one direction) is indicated by an arrow A, and the upper vertical direction (one direction forward) is indicated by an arrow A1.

  In the peeling method of the mortar 72 using the peeling apparatus 10, the guide groove creating process, the cutter installation hole creating process, the apparatus fixing process, the first moving process (peeling process), the first advance / retreat process (shaft first advance / retreat process), the first 2 movement process, second advance / retreat process (shaft second advance / retreat process), third move process, third advance / retreat process (shaft third advance / retreat process), fourth move process, fourth advance / retreat process (shaft fourth advance / retreat process), Each step of the device fixing release step is performed.

  Hereinafter, the peeling method (peeling procedure) in the apparatus 10 will be described as an example in which the peeling device 10 is installed on the inner wall 80 of a reinforced concrete building (structure) and the mortar 72 of the inner wall 80 is peeled off. The peeling device 10 is installed not only on the inner wall 80 of the building but also on the floor slab, cantilever slab, ceiling slab, column, beam of the building, and may be used for peeling the mortar 72 applied to them. it can. In these drawings, the peeling device 10 is installed in the vertical direction on the inner wall 80 of the building (structure), but there is no particular limitation on the installation direction of the device 10 on the inner wall 80 of the building (the direction in which the guide member 11 extends). If the space for installing the device 10 can be secured, the device 10 can be installed in any direction.

  First, as a preliminary preparation for carrying out these steps, a peeling position of the inner wall 80 from which the mortar 72 is peeled is determined, and a peeling width dimension of the mortar 72 (a dimension in the width direction of the mortar 72 to be peeled) is determined. The peeling length dimension (one-way dimension of the mortar 72 to be peeled) is determined, and the peeling depth dimension of the mortar 72 (the depth dimension of the mortar 72 to be peeled toward the concrete casing) is determined. The width dimension of the blade edge 66 of the cutter 18 is determined by the peel width dimension of the mortar 72. Specifically, when the peeling width dimension of the mortar 72 is large, a cutter 18 having a large width dimension of the blade edge 66 is used. When the peeling width dimension of the mortar 72 is small, the cutter 18 having a small width dimension of the blade edge 66 is used. used. In the peeling apparatus 10, the width width dimension of the mortar 72 to be peeled can be freely adjusted by adjusting the width direction dimension (the dimension in a direction crossing one direction) of the blade edge 66 of the cutter 18.

  After determining these dimensions, as shown in FIG. 10, two guide grooves 73 extending straight in the vertical direction (one direction) along the outer edge of the peeling width of the mortar 72 are inserted (guide groove forming step). Specifically, using a concrete cutter, the guide groove 73 is formed by cutting the mortar 72 along the outer edge of the peeling width. The groove depths of the guide grooves 73 are the same as the peeling depth of the mortar 72.

  The guide groove 73 is formed to peel only the mortar 72 applied on the inside of the grooves 73 (between the grooves 73) and prevent the mortar 72 applied on the outside of the guide groove 73. When the mortar 72 is peeled off over the entire inner wall 80, the creation of the guide groove 73 can be omitted. After forming the guide groove 73, the mortar 72 between the guide grooves 73 is inserted, and a cutter installation hole 74 into which the blade edge 66 of the cutter 18 enters is drilled at that position (cutter installation hole creating step). Specifically, a cutter installation hole 74 having a length and width substantially the same as the length dimension and width dimension of the blade edge 66 of the cutter 18 is made using a core drill.

  After making the guide groove 73 and making the cutter installation hole 74, the peeling device 10 is installed and fixed (device fixing step). In the peeling method, the guide member 11 of the peeling device 10 is fixed to the inner wall 80 via a fixing means. As an example of the fixing means, after drilling an anchor hole in the ceiling 81 (concrete frame) of the building above the guide groove and drilling an anchor hole in the floor 82 (concrete frame) of the building below the guide groove A fixing bracket 75 having a U-shaped cross-section is installed on the ceiling 81 and the floor 82, and the fixing bolt 75 is screwed into a bolt hole and an anchor hole formed in the fixing bracket 75 to attach the fixing bracket 75 to the ceiling 81 and the floor. It fixes to 82. Next, after the upper end portion 77 of the guide member 11 is engaged inside the fixing bracket 75 of the ceiling 81 and the lower end portion 78 of the guide member 11 is engaged inside the fixing bracket 75 of the floor 82, the guide member 11. The guide bolt 11 is fixed to the fixing bracket 75 by screwing the fixing bolt 79 into the bolt holes formed in the upper and lower end portions 77 and 78 (including the slide rail 44) and the fixing bracket 75.

  When the guide member 11 is fixed to the fixing bracket 75, the peeling device 10 is firmly fixed to the inner wall 80, and movement of the guide member 11 (peeling device 10) in a direction away from the outer surface of the mortar 72 is prevented. The fixing means 12 is not limited to that shown in the figure, and any other fixing means can be adopted as long as the peeling device 10 can be firmly fixed to the inner wall 80. As shown in FIG. 11, the guide member 11 is spaced apart from the outer surface of the mortar 72 by a predetermined dimension and extends in the vertical direction (one direction) substantially parallel to the outer surface of the mortar 72. Further, as shown in FIG. 12, the guide member 11 is substantially parallel to the fitting groove 73 and located between the guide grooves 73, and the hydraulic jack 13 (the cylinder 26 and the piston rod 27) is separated from the outer surface of the mortar 72. However, it is located between the guide member 11 and the mortar 72.

  In the peeling apparatus 10, during the peeling operation for moving the blade edge 66 of the cutter 18 upward and downward (one direction forward), the force for moving the guide member 11 in the direction away from the outer surface of the mortar 72 is applied from the cutter 18 to the guide member. 11, the movement of the guide member 11 (peeling device 10) in the direction away from the outer surface of the mortar 72 is prevented by the fixing means, so that the blade edge 66 of the cutter 18 is securely bited into the mortar 72. Can do.

  After the guide member 11 (peeling device 10) is installed and fixed on the inner wall 80, a switch (not shown) displayed on the multi-touch panel 91 of the controller 90 is turned ON. When the switch of the controller 90 is turned on, various conditions stored in the hard disk of the controller 90 are displayed on the multi-touch panel 91, and it is confirmed whether or not these conditions have been changed. As various conditions, the first incidence number is 6, the second incidence number is 6, the third incidence number is 6, the fourth incidence number is 6, the first time is 0.5 seconds, and the second time. Is set to 0.5 seconds (the fifth to eighth incidence times are blank). When the switch of the controller 90 is turned on, the electric hydraulic pump is turned on, and the first and second optical sensors 19 and 20 are turned on. When the first and second optical sensors 19 and 20 are turned on, the first laser light is emitted from the first light emitting unit 68 and the second laser light is emitted from the second light emitting unit.

  When the guide member 11 (peeling device 10) is installed on the inner wall 80 and the switch of the controller 90 is turned on, the first connecting shaft 29 is connected to the first and second through holes 25 as shown in FIGS. , 38 and the second connecting shaft 49 is withdrawn from the first and third through holes 25, 57. Further, the first light emitting unit 68 and the first light receiving unit 69 of the first optical sensor 19 face each other with the first through hole 25 interposed therebetween, and the first laser light emitted from the first light emitting unit 68 is the first light receiving unit. 69, the first optical sensor 19 is in a conducting state, and the second light emitting unit 70 and the second light receiving unit 71 of the second optical sensor 20 are opposed to each other with the first through hole 25 interposed therebetween. The second laser light emitted from the unit 70 is incident on the second light receiving unit 71 and the second photosensor 20 is in a conducting state.

  When the central processing unit of the controller 90 turns on the switch of the controller 90, the first and second photosensors 19 and 20 are in a conducting state, but the conducting state of the first photosensor 19 is set to the first number of incidents. While not counting, the conduction state of the second photosensor 20 is not counted as the second number of incidents. When there is no change in various conditions, a peeling start (forward advance) button (not shown) displayed on the multi-touch panel 91 is pressed.

  When the peeling start (start advance) button is pressed, the central processing unit of the controller 90 causes the first connection shaft 29 to enter the first and second through holes 25 and 38, and the second connection shaft 49 to be the first and first. The electric hydraulic pump is operated in a state in which it is retracted from the three through holes 25 and 57, and the piston rod 27 is gradually extended upward (in one direction forward) and the second connecting member 15 is moved up and down along the guide member 11. Move gradually upward in the direction. The movement of the second connecting member 15 causes the blade edge 66 of the cutter 18 to gradually advance upward (upward in one direction), and the blade edge 66 of the cutter 18 that bites into the mortar 72 has a predetermined thickness from the inner wall 80 of the reinforced concrete building. The mortar 72 is peeled off (first moving step (peeling step)).

  In the peeling method, the cutting edge 66 of the cutter 18 of the peeling apparatus 10 moves straight upward (one direction forward) and acts so that the cutting edge 66 peels off the mortar 72. 66 does not rub against each other and no loud cutting noise is generated. The sound pressure level generated when the mortar 72 is peeled is in the range of 40 to 80 dB. The sound pressure level is a value measured by using a sound level meter and separating the sound level meter from the peeling device 10 by 1.2 m.

  In the process of moving the cutter 18 (piston rod 27) upward and downward, the force that moves the first connecting member 14 and the cylinder 26 downward and downward in the vertical direction (one-way rearward) from the cutter 18 to the first connecting member 14 and Although acting on the cylinder 26, the first connecting shaft 29 has entered the first and second through holes 25, 38, and therefore the first connecting member 29 and the cylinder 26 are moved downward in the vertical direction by the first connecting shaft 29. Is blocked.

  Further, in the process of moving the cutter 18 (piston rod 27) upward and downward, a force that moves the guide member 11 in a direction to move away from the outer surface of the mortar 72 acts on the guide member 11 from the cutter 18; The upper end 77 of the guide member 11 is firmly fixed to the ceiling 81 (concrete casing), and the lower end 78 of the guide member 11 is firmly fixed to the floor 82 (concrete casing) via the fixing means. The fixed state of the guide member 11 can be maintained, and the guide member 11 does not move in a direction away from the outer surface of the mortar 72. In the peeling device 10, during the peeling operation of the mortar 72, the guide member 11 does not move in a direction away from the outer surface of the mortar 72, and the fixed state of the guide member 11 is maintained. Can be surely bitten into the mortar 72, and the mortar 72 can be smoothly peeled off from the inner wall 80.

  In the process in which the piston rod 27 and the second connecting member 15 gradually move upward and downward, the second light emitting portion 70 and the second light receiving portion 71 of the second optical sensor 20 gradually move upward and downward, The light emitting unit 70 and the second light receiving unit 71 sequentially pass through the first through hole 25. When the second light emitting unit 70 and the second light receiving unit 71 are opposed to each other with the first through hole 25 interposed therebetween, the second photosensor 20 is turned on (ON state) each time. The central processing unit of the controller counts the conduction state (first number of incidents) of the second optical sensor 20 in the process in which the piston rod 27 and the second connecting member 15 gradually move upward and downward, and the first number of incidents is six. (When the second optical sensor 20 passes through the five first through holes 25 and reaches the sixth through hole 25), the operation of the electric hydraulic pump is stopped, and the piston rod 27 is stopped (see FIGS. 13 and 14).

  The central processing unit of the controller 90 has the first light-emitting unit 70 and the second light-receiving unit 71 facing each other in the seventh through-hole 25 counted from the first through-hole 25 at the peeling start position of the mortar 72, When the number of incidents reached 6, the second time after the second photosensor 20 became conductive (ON state) in the through hole 25 where the first number of incidents reached 6 was measured and measured. When the second time has passed 0.5 seconds, the extension of the piston rod 27 is stopped. When the extension of the piston rod 27 is stopped, the movement of the second connecting member 15 and the forward movement of the cutter 18 are stopped, and the peeling of the mortar 72 is temporarily stopped.

  In the peeling method, the extension dimension of the piston rod 27 (the movement dimension of the second connecting member 15) can be adjusted by setting the first incidence number of the second optical sensor 20. For example, if the first number of incidences is set to three, when the first number of incidences reaches three (the second photosensor 20 passes through the two first through holes 25 and the third through hole When the first incidence number reaches 10 times (when the second photosensor 20 is 9), the extension of the piston rod 27 is stopped when the first incidence number is set to 10. When passing through the first through hole 25 and reaching the tenth through hole 25), the extension of the piston rod 27 stops.

  The central processing unit of the controller 90 operates the second motor 59 of the second advancing / retracting mechanism 53 after the second time has elapsed (after the piston rod 27 has extended upward in the vertical direction (forward in one direction)). The gear 60 is rotated, the second pinion 61 (second connecting shaft 49) is moved in the width direction, and the pinion 61 (connecting shaft 49) is moved through the first and third through holes 25 and 57 (first penetration at the initial peeling position). The sixth through hole 25) is counted from the hole 25. After the second pinion 61 enters the first and third through holes 25 and 57, the central processing unit of the controller 90 operates the first motor 40 of the first advance / retreat mechanism 33 to rotate the first gear 41, The first pinion 42 (first connection shaft 29) is moved in the width direction, and the pinion 42 (connection shaft 29) is retracted from the first and second through holes 25, 38 (first advance / retreat process (shaft first advance / retreat process) (See FIGS. 16 and 17).

  In the peeling method, after the second time has elapsed, the extension of the piston rod 27 is stopped, so that the axial center of the first through hole 25 and the axial center of the second pinion 61 (second connecting shaft 49) are Match. In the peeling method, the extension speed of the piston rod 27 is set so that the axial center of the first through hole 25 and the axial center of the second pinion 61 coincide after the second time has elapsed. If the second pinion 61 is moved in the width direction before the second time elapses, the axial center of the first through hole 25 and the axial center of the pinion 61 do not coincide with each other, and the pinion 61 enters the through hole 25. Although it cannot enter, in this peeling method, since the pinion 61 is moved in the width direction after the second time has elapsed, the pinion 61 can surely enter the through hole 25.

  When the second pinion 61 (second connection shaft 49) enters the first and third through holes 25 and 57, the second connection member 15 cannot move, and the first pinion 42 (first connection shaft 29). The first connecting member 14 can be moved by retreating from the first and second through holes 25 and 38. The central processing unit of the controller 90 includes the second pinion 61 (second connection shaft 49) entering the first and third through holes 25 and 57, and the first pinion 42 (first connection shaft 29) being the first and third. The electric hydraulic pump is operated in a state where the second through holes 25 and 38 are retracted, and the cylinder 26 is gradually moved upward (upward in one direction) (the piston rod 27 gradually enters the inside of the cylinder 26). The first connecting member 14 is gradually moved upward and downward along the guide member 11 (second moving step).

  In the process in which the cylinder 26 and the first connecting member 14 gradually move upward and downward, the first light emission unit 68 and the first light receiving unit 69 of the first optical sensor 19 gradually move upward and downward, and the first light emission. The portion 68 and the first light receiving portion 69 sequentially pass through the first through hole 25. When the first light emitting unit 68 and the first light receiving unit 69 are opposed to each other with the first through hole 25 interposed therebetween, the first photosensor 19 is turned on each time (ON state). The central processing unit of the controller 90 counts the conduction state (second incidence number) of the first optical sensor 19 in the process in which the cylinder 26 and the first connection member 14 gradually move upward and downward, and the second incidence number is 6. (When the first optical sensor 19 passes through the five first through holes 25 and reaches the sixth through hole 25), the operation of the electric hydraulic pump is stopped, and the cylinder 26 (The piston rod 27 enters the cylinder 26) is stopped (see FIGS. 18 and 19).

  The central processing unit of the controller 90 is such that the first light emitting unit 68 and the first light receiving unit 69 face each other at the seventh through hole 25 counted from the first through hole 25 at the peeling start position of the mortar 72, and the second When the number of incidents reached 6, the first time after the first photosensor 20 became conductive (ON state) in the through hole 25 where the second number of incidents reached 6 was measured and measured. When the first time has passed 0.5 seconds, the movement of the cylinder 26 is stopped. When the movement of the cylinder 26 stops, the movement of the first connecting member 14 stops.

  In the peeling method, the moving dimension of the cylinder 26 (the moving dimension of the first connecting member 14) can be adjusted by setting the second incidence number of the first optical sensor 19. For example, if the second number of incidents is set to three, when the second number of incidents reaches three (the first optical sensor 19 passes through the two first through holes 25 and the third through hole The movement of the cylinder 26 is stopped and the second incidence number is set to 10 (when the first light sensor 19 has nine first light sensors 19). When the first through hole 25 is passed and the tenth through hole 25 is reached), the movement of the cylinder 26 stops.

The central processing unit of the controller 90 operates the first motor 40 of the first advancing / retracting mechanism 33 after the first time has elapsed (after the cylinder 26 has moved upward and downward (one direction forward)) to move the first gear. 41 is rotated, the first pinion 42 (first connection shaft 29) is moved in the width direction, and the pinion 42 (connection shaft 29) is moved to the first and second through holes 25 and 38 (first through holes at the initial peeling position). 25, the sixth through hole 25) is counted. After the first pinion 42 enters the first and second through holes 25 and 38, the central processing unit of the controller operates the second motor 59 of the second advance / retreat mechanism 53 to rotate the second gear 60, and The 2 pinion 61 (second connecting shaft 49) is moved in the width direction, and the pinion 61 (connecting shaft 49) is withdrawn from the first and third through holes 25 and 57 (second forward / backward step (shaft second forward / backward step)). (See FIGS. 20 and 21).

  In the peeling method, after the first time has elapsed, the movement of the cylinder 26 is stopped, so that the axial center of the first through hole 25 and the axial center of the first pinion 42 (first connection shaft 29) are located. Match. In the peeling method, after the elapse of the first time, the moving speed of the cylinder 26 (to the cylinder 26 of the piston rod 27 so that the axial center of the first through hole 25 and the axial center of the first pinion 42 coincide with each other). ) Is set. If the first pinion 42 is moved in the width direction before the first time elapses, the axial center of the first through hole 25 and the axial center of the pinion 42 do not coincide with each other, and the pinion 42 enters the through hole 25. Although it cannot enter, in this peeling method, since the pinion 42 is moved in the width direction after the first time has elapsed, the pinion 42 can surely enter the through hole 25.

  When the second pinion 42 (first connection shaft 29) enters the first and second through holes 25 and 38, the first connection member 14 cannot move, and the second pinion 61 (second connection shaft 49). The second connecting member 15 can be moved by retreating from the first and third through holes 25 and 57. In the peeling apparatus 10, one peeling process is completed by the first movement process (peeling process), the first advance / retreat process (shaft first advance / retreat process), the second move process, and the second advance / retreat process (shaft second advance / retreat process). Then, the next first moving step (peeling step) is performed.

FIG. 24 is a side view of the peeling apparatus 10 showing the peeling method continued from FIG. 22, and FIG. 25 is a front view of the peeling apparatus 10 in the state of FIG. FIG. 26 is a side view of the peeling apparatus 10 in a state where the peeling work of the mortar 72 has been completed. 22 to 26, the vertical direction (one direction) is indicated by an arrow A, and the upper vertical direction (one direction forward) is indicated by an arrow A1.

  When the peel (forward) button displayed on the multi-touch panel 91 is pressed, the central processing unit of the controller 90 causes the first connection shaft 29 to enter the first and second through holes 25 and 38 and the second connection shaft 49. Is retracted from the first and third through holes 25 and 57, the electric hydraulic pump is operated, and the piston rod 27 is gradually extended upward (one-way forward) and the second connecting member 15 is guided to the guide member. 11 is moved upward and downward in the vertical direction. The movement of the second connecting member 15 causes the blade edge 66 of the cutter 18 to gradually advance upward (upward in one direction), and the blade edge 66 of the cutter 18 that bites into the mortar 72 has a predetermined thickness from the inner wall 80 of the reinforced concrete building. The mortar 72 is peeled off (first moving step (peeling step)).

  In the process in which the piston rod 27 and the second connecting member 15 gradually move upward and downward, the second light emitting portion 70 and the second light receiving portion 71 of the second optical sensor 20 gradually move upward and downward, The light emitting unit 70 and the second light receiving unit 71 sequentially pass through the first through hole 25. When the second light emitting unit 70 and the second light receiving unit 71 are opposed to each other with the first through hole 25 interposed therebetween, the second photosensor 20 is turned on (ON state) each time. The central processing unit of the controller 90 counts the conduction state (first incidence number) of the second photosensor 20 in the process in which the piston rod 27 and the second connecting member 15 gradually move upward and downward, and the first incidence number is When it reaches six times (when the second optical sensor 20 passes through the five first through holes 25 and reaches the sixth through hole 25), the operation of the electric hydraulic pump is stopped, and the piston The extension of the rod 27 is stopped (see FIGS. 22 and 23).

  The central processing unit of the controller 90 is opposed to the second light emitting unit 70 and the second light receiving unit 71 in the seventh through hole 25 counted from the first through hole 25 at the first peeling completion position of the mortar 72. When the first number of incidences reaches six times, the second time after the second photosensor 20 becomes conductive (ON state) is measured in the through hole 25 where the first number of incidences reaches six times, When the measured second time has passed 0.5 seconds, the extension of the piston rod 27 is stopped. When the extension of the piston rod 27 is stopped, the movement of the second connecting member 15 and the forward movement of the cutter 18 are stopped, and the peeling of the mortar 72 is temporarily stopped.

  The central processing unit of the controller 90 operates the second motor 59 of the second advancing / retracting mechanism 53 after the second time has elapsed (after the piston rod 27 has extended upward in the vertical direction (forward in one direction)). The gear 60 is rotated, the second pinion 61 (second connecting shaft 49) is moved in the width direction, and the pinion 61 (connecting shaft 49) is moved through the first and third through holes 25 and 57 (first penetration at the initial peeling position). The sixth through hole 25) is counted from the hole 25. After the second pinion 61 enters the first and third through holes 25 and 57, the central processing unit of the controller 90 operates the first motor 40 of the first advance / retreat mechanism 33 to rotate the first gear 41, The first pinion 42 (first connection shaft 29) is moved in the width direction, and the pinion 42 (connection shaft 29) is retracted from the first and second through holes 25, 38 (first advance / retreat process (shaft first advance / retreat process) )).

  When the second pinion 61 (second connection shaft 49) enters the first and third through holes 25 and 57, the second connection member 15 cannot move, and the first pinion 42 (first connection shaft 29). The first connecting member 14 can be moved by retreating from the first and second through holes 25 and 38. The central processing unit of the controller 90 includes the second pinion 61 (second connection shaft 49) entering the first and third through holes 25 and 57, and the first pinion 42 (first connection shaft 29) being the first and third. The electric hydraulic pump is operated in a state where the second through holes 25 and 38 are retracted, and the cylinder 26 is gradually moved upward (upward in one direction) (the piston rod 27 gradually enters the inside of the cylinder 26). The first connecting member 14 is gradually moved upward and downward along the guide member 11 (second moving step).

  In the process in which the cylinder 26 and the first connecting member 14 gradually move upward and downward, the first light emission unit 68 and the first light receiving unit 69 of the first optical sensor 19 gradually move upward and downward, and the first light emission. The portion 68 and the first light receiving portion 69 sequentially pass through the first through hole 25. When the first light emitting unit 68 and the first light receiving unit 69 are opposed to each other with the first through hole 25 interposed therebetween, the first photosensor 19 is turned on each time (ON state). The central processing unit of the controller 90 counts the conduction state (second incidence number) of the first optical sensor 19 in the process in which the cylinder 26 and the first connection member 14 gradually move upward and downward, and the second incidence number is 6. (When the first optical sensor 19 passes through the five first through holes 25 and reaches the sixth through hole 25), the operation of the electric hydraulic pump is stopped, and the cylinder 26 Movement (entrance of the piston rod 27 into the cylinder 26) is stopped.

  The central processing unit of the controller 90 is configured such that the first light emitting unit 68 and the first light receiving unit 69 are opposed to each other in the seventh through hole 25 counted from the first through hole 25 at the initial peeling position of the mortar 72, and the second number of incidents. Has reached six times, the first time after the first photosensor 20 is in the conductive state (ON state) in the through-hole 25 where the second incidence number has reached six times is measured, and the measured first time is measured. When the time has passed 0.5 seconds, the movement of the cylinder 26 is stopped.

  The central processing unit of the controller 90 operates the first motor 40 of the first advancing / retracting mechanism 33 after the first time has elapsed (after the cylinder 26 has moved upward and downward (one direction forward)) to move the first gear. 41 is rotated, the first pinion 42 (first connection shaft 29) is moved in the width direction, and the pinion 42 (connection shaft 29) is moved to the first and second through holes 25 and 38 (first through holes at the initial peeling position). 25, the sixth through hole 25) is counted. After the first pinion 42 enters the first and second through holes 25 and 38, the central processing unit of the controller operates the second motor 59 of the second advance / retreat mechanism 53 to rotate the second gear 60, and The 2 pinion 61 (second connecting shaft 49) is moved in the width direction, and the pinion 61 (connecting shaft 49) is withdrawn from the first and third through holes 25 and 57 (second forward / backward step (shaft second forward / backward step)). (See FIGS. 24 and 25).

  When the peeling (forward) button displayed on the multi-touch panel 91 is pressed, the central processing unit of the controller 90 operates the electric hydraulic pump, and gradually extends the piston rod 27 upward and downward (one-way forward). 2 The connecting member 15 is gradually moved upward and downward along the guide member 11. The movement of the second connecting member 15 causes the blade edge 66 of the cutter 18 to gradually advance upward (upward in one direction), and the blade edge 66 of the cutter 18 moves from the inner wall 80 of the reinforced concrete building to a mortar 72 having a predetermined thickness. Is peeled off (first moving step (peeling step)). As shown in FIG. 26, all the mortar 72 from the peeling start position to the peeling end position is peeled off, and the peeling work is completed.

  In the peeling method, the first connecting shaft 29 of the peeling device 10 enters the first and second through holes 25 and 38 and the second connecting shaft 49 is withdrawn from the first and third through holes 25 and 57. The piston rod 27 gradually extends upward in the vertical direction (forward in one direction), and the second connecting member 15 gradually moves upward in the vertical direction along the guide member 11, whereby the cutter 18 moves upward in the vertical direction. The blade edge 66 of the cutter 18 peels off the mortar 72 having a predetermined thickness from the inner wall 80 (peeling) while gradually moving forward, so that the cutting sound of the mortar 72 and the blade edge 66 of the cutter 18 rub against each other. There is no generation, and the sound generated during the peeling operation can be made an acceptable quiet sound.

  In the peeling method, the second connecting shaft 49 of the peeling device 10 enters the first and third through holes 25 and 57 and the first connecting shaft 29 is withdrawn from the first and second through holes 25 and 38. Since the cylinder 26 gradually moves upward (upward in one direction) and the first connecting member 14 gradually moves upward and downward along the guide member 11, the hydraulic jack 13 is in a state at the time of the initial movement of the peeling operation. The peeling operation can be started again from this state.

  In the peeling method, a force (torque) is linearly transmitted from the piston rod 26 of the hydraulic jack 13 of the peeling apparatus 10 to the blade edge 66 of the cutter 18, and the straight traveling force of the cutter 18 is concentrated on the peeling portion of the mortar 72. Thus, since a large peeling force acts on the mortar 72, the mortar 72 can be smoothly and reliably peeled even when the mortar 72 is firmly constructed.

  Since the peeling method can use the hydraulic jack 13 to smoothly peel the mortar 72 from the inner wall 80 of the building (structure), the peeling work of the mortar 72 can be efficiently completed in a short construction period. In addition, the mortar 72 can be peeled from the inner wall 80 over a wide range at a time, and the peeling work can be performed at a low cost. Since the peeling method does not transmit unnecessary vibration to the building when the mortar 72 is peeled off, the mortar 72 can be peeled while maintaining the state of the building without damaging the building. Further, the mortar 72 can be uniformly peeled from the building with high accuracy in a short time, and the peeling work can be performed in a favorable environment with less dust and dust generation.

FIG. 29 is a side view of the peeling apparatus 10 showing the peeling method continuing from FIG. 28, and FIG. 30 is a side view of the peeling apparatus 10 showing the peeling method continuing from FIG. FIG. 31 is a side view of the peeling apparatus 10 showing the peeling method continued from FIG. 27 to 31, the vertical direction (one direction) is indicated by an arrow A, and the lower direction (one direction rear) is indicated by an arrow A2.

  As shown in FIG. 26, after peeling off all the mortars 72 from the peeling start position to the peeling end position and finishing the peeling work, when a backward start button (not shown) displayed on the multi-touch panel 91 is pressed, The central processing unit of the controller 90 is in a state in which the first connection shaft 29 enters the first and second through holes 25 and 38 and the second connection shaft 49 has retreated from the first and third through holes 25 and 57. Then, the electric hydraulic pump is operated to cause the piston rod 27 to gradually enter the inside of the cylinder 26, and the second connecting member 15 is gradually moved downward in the vertical direction (one-way rearward) along the guide member 11. The blade edge 66 is gradually moved downward in the vertical direction (third movement step).

  In the process in which the piston rod 27 and the second connecting member 15 gradually move downward in the vertical direction, the second light emitting portion 70 and the second light receiving portion 71 of the second optical sensor 20 gradually move downward in the vertical direction, The light emitting unit 70 and the second light receiving unit 71 sequentially pass through the first through hole 25. When the second light emitting unit 70 and the second light receiving unit 71 are opposed to each other with the first through hole 25 interposed therebetween, the second photosensor 20 is turned on (ON state) each time. The central processing unit of the controller 90 counts the conduction state (third incidence number) of the second photosensor 20 in the process in which the piston rod 27 and the second connecting member 15 gradually move downward in the vertical direction, and the third incidence number is When it reaches six times (when the second optical sensor 20 passes through the five first through holes 25 and reaches the sixth through hole 25), the operation of the electric hydraulic pump is stopped, and the piston The entry of the rod 27 into the cylinder 26 is stopped (see FIG. 27).

  The central processing unit of the controller 90 is opposed to the second light emitting unit 70 and the second light receiving unit 71 in the seventh through hole 25 counted from the first through hole 25 at the peeling end position of the mortar 72 shown in FIG. When the third incidence number reaches six times, the second time after the second photosensor 20 becomes conductive (ON state) is measured in the through-hole 25 where the third incidence number reaches six times, When the measured second time has passed 0.5 seconds, the entry of the piston rod 27 into the cylinder 26 is stopped. When the piston rod 27 stops, the movement of the second connecting member 15 and the cutter 18 in the vertical direction stops.

  In the peeling method, by setting the third incidence number of the second optical sensor 20, the dimension of the piston rod 27 entering the cylinder 26 (the dimension of movement of the second connecting member 15 downward in the vertical direction (one direction rearward)). ) Can be adjusted. For example, when the third number of incidences is set to three, when the third number of incidences reaches three (the second photosensor 20 passes through the two first through holes 25 and the third through hole 25), when the piston rod 27 stops entering the cylinder 26 and the third incidence number is set to 10, the third incidence number is reached (second optical sensor). When 20 passes through the nine first through holes 25 and reaches the tenth through hole 25), the piston rod 27 stops entering the cylinder 26.

  The central processing unit of the controller 90 operates the second motor 59 of the second advancing / retracting mechanism 53 after the second time has elapsed (after the piston rod 27 has extended downward in the vertical direction (one-way rearward)). The gear 60 is rotated, the second pinion 61 (second connecting shaft 49) is moved in the width direction, and the pinion 61 (connecting shaft 49) is moved through the first and third through holes 25 and 57 (first penetration at the initial peeling position). The sixth through hole 25) is counted from the hole 25. After the second pinion 61 enters the first and third through holes 25 and 57, the central processing unit of the controller 90 operates the first motor 40 of the first advance / retreat mechanism 33 to rotate the first gear 41, The first pinion 42 (first connection shaft 29) is moved in the width direction, and the pinion 42 (connection shaft 29) is withdrawn from the first and second through holes 25, 38 (third advance / retreat step (shaft third advance / retreat step) )) (See FIG. 28).

  In the peeling method, after the second time has elapsed, the entry of the piston rod 27 into the cylinder 26 is stopped, so that the axial center of the first through hole 25 and the second pinion 61 (second connecting shaft 49) The axial center coincides. In the peeling method, after the elapse of the second time, the approach speed of the piston rod 27 into the cylinder 26 is set so that the axial center of the first through hole 25 and the axial center of the second pinion 61 coincide. Has been. If the second pinion 61 is moved in the width direction before the second time elapses, the axial center of the first through hole 25 and the axial center of the pinion 61 do not coincide with each other, and the pinion 61 enters the through hole 25. Although it cannot enter, in this peeling method, since the pinion 61 is moved in the width direction after the second time has elapsed, the pinion 61 can surely enter the through hole 25.

  When the second pinion 61 (second connection shaft 49) enters the first and third through holes 25 and 57, the second connection member 15 cannot move, and the first pinion 42 (first connection shaft 29). The first connecting member 14 can be moved by retreating from the first and second through holes 25 and 38. When the backward start button displayed on the multi-touch panel 91 is pressed, the central processing unit of the controller 90 causes the second pinion 61 (second connection shaft 49) to enter the first and third through holes 25, 57 and With the one pinion 42 (the first connecting shaft 29) retracted from the first and second through holes 25, 38, the electric hydraulic pump is operated, and the cylinder 26 is gradually moved downward in the vertical direction (backward in one direction) ( The piston rod 27 is gradually advanced from the inside of the cylinder 26), and the first connecting member 14 is gradually moved downward along the guide member 11 (fourth moving step).

  In the process in which the cylinder 26 and the first connecting member 14 are gradually moved downward in the vertical direction, the first light emission unit 68 and the first light receiving unit 69 of the first optical sensor 19 are gradually moved downward in the vertical direction, and the first light emission is performed. The portion 68 and the first light receiving portion 69 sequentially pass through the first through hole 25. When the first light emitting unit 68 and the first light receiving unit 69 are opposed to each other with the first through hole 25 interposed therebetween, the first photosensor 19 is turned on each time (ON state). The central processing unit of the controller 90 counts the conduction state (fourth incidence number) of the first optical sensor 19 in the process in which the cylinder 26 and the first connection member 14 gradually move downward in the vertical direction, and the fourth incidence number is six. (When the first optical sensor 19 passes through the five first through holes 25 and reaches the sixth through hole 25), the operation of the electric hydraulic pump is stopped, and the cylinder 26 (The advance of the piston rod 27 from the inside of the cylinder 26) is stopped (see FIG. 29).

  The central processing unit of the controller 90 is such that the first light emitting unit 68 and the first light receiving unit 69 are opposed to each other in the seventh through hole 25 counted from the first through hole 25 at the initial peeling position of the mortar 72, and the fourth processing unit. When the number of incidents reached 6, the first time after the first photosensor 20 became conductive (ON state) in the through hole 25 where the fourth number of incidents reached 6 was measured and measured. When the first time has passed 0.5 seconds, the movement of the cylinder 26 is stopped. When the movement of the cylinder 26 stops, the movement of the first connecting member 14 stops.
