Description

  The present invention relates to an adhesive injection device for a pinning method and a pinning method for injecting an adhesive into an insertion hole penetrating a finishing material and drilling a casing to a predetermined depth while sealing the opening. It is.

Conventionally, an adhesive injector comprising an injection nozzle and an injector body is known as this type of adhesive injector (see Patent Document 1).
In this case, the injection nozzle has an injection needle-like nozzle inner cylinder, and a nozzle body that slidably supports the nozzle inner cylinder and has a tapered sealing member. In addition, the injector body has a cylindrical casing for storing the adhesive, a pump body in which the casing is detachably attached, a built-in manual resin pump, and a lever that is attached to the pump body and pumps the resin pump section. And have.
In the adhesive injection operation, the nozzle inner cylinder of the injection nozzle is inserted into the insertion hole, and the lever is reciprocally rotated (pumped) while the sealing member is in close contact with the opening of the insertion hole. By this pumping, the adhesive of the injector main body is sent out, and first, the nozzle inner cylinder advances by receiving the adhesive injection pressure, and its tip reaches the deepest part of the insertion hole. Thereafter, the adhesive starts to be discharged from the tip of the nozzle inner cylinder, and the adhesive is gradually filled from the deepest part of the insertion hole. As pumping continues further, the adhesive will also fill the voids ("floating") that occur between the concrete frame and the mortar, and the gaps that form between the mortar and the tile ("floating"). . In this pinning method, after injecting adhesive into the insertion hole and “floating” in this way, anchor pins are inserted into the insertion holes, and finishing materials such as tiles are anchored to the concrete frame.

JP 2008-115527 A

In such a conventional adhesive injector, the adhesive is distributed not only in the insertion hole into which the anchor pin is inserted but also in “floating”. Whether or not the adhesive is properly injected into the “float” is a sensory perception recognized by the heavy pumping. For this reason, if the pumping is insufficient, the injection of the adhesive into the “float” becomes inappropriate, and if the pumping is excessive, the “float” opens and there is a risk that the mortar or tile peels off. That is, there has been a problem that requires skill in the adhesive injection operation.
In pumping, the casing portion is held with one hand, the sealing member is pressed against the opening of the insertion hole through the casing, and the lever is pumped with the other hand. For this reason, the operation becomes complicated, and in this respect as well, there is a problem that requires skill in the adhesive injection work.

  An object of the present invention is to provide an adhesive injection device and a pinning method capable of easily and reliably performing an adhesive injection operation into an insertion hole without requiring skill.

  The adhesive injection device of the present invention is an adhesive injection device for a pinning method, in which an adhesive is injected while sealing an opening into an insertion hole penetrating a finishing material and drilling a casing to a predetermined depth.

An adhesive injection portion that injects an adhesive while sealing the opening, and a pressurized gas supply means that is provided in the adhesive storage portion and supplies the adhesive to the adhesive injection portion with a predetermined gas pressure. And a pressurized gas introduction section to be connected.

According to this configuration, when the open / close valve mechanism is “opened” by introducing the pressurized gas into the adhesive reservoir by the pressurized gas supply means connected to the pressurized gas introduction unit, the pressurized gas is Due to the predetermined gas pressure, the adhesive in the adhesive reservoir is supplied to the adhesive injection part, and is injected into the insertion hole from the adhesive injection part. That is, the operator applies the insertion hole to the insertion hole with a predetermined gas pressure simply by “opening” the opening / closing valve mechanism so as to seal the opening.
When the insertion hole and the floating portion connected thereto are filled with the adhesive, the pressure in the sealed insertion hole and the gas pressure are balanced, and the adhesive is not injected. Here, the operator performs a “close” operation on the on-off valve mechanism so that the adhesive injection portion is pulled away from the insertion hole. In addition, since the adhesive is supplied at a predetermined gas pressure, the amount of adhesive injected is not insufficient or excessive by adjusting the gas pressure appropriately. As described above, the operation of injecting the adhesive into the insertion hole can be easily and reliably performed without requiring skill.

From this state, the gas on-off valve mechanism is operated to close the gas flow path, whereby the adhesive reservoir is opened to the atmosphere (pressurized gas is released), and the supply of the adhesive is stopped. In this case, when exchanging the resin tube, it is not necessary to remove the gas cylinder from the pressurized gas introducing portion, and the handleability can be improved.

  Further, the pressurized gas supply means is a gas cylinder filled with a pressurized gas, and the pressurized gas introduction part has a gas inlet for injecting the pressurized gas of the gas cylinder into the adhesive reservoir. It is preferable.

The pressurized gas is preferably injected into the adhesive reservoir by a disposable gas cylinder (cassette cylinder) or the like. That is, the stem of the gas cylinder is pushed into the gas injection port, and the pressurized gas is introduced into the adhesive reservoir. Also in this case, it is preferable to adjust the gas pressure by component adjustment or the like using a pressurized gas such as nitrogen or carbon dioxide or a liquefied gas such as LPG, chlorofluorocarbon, halon, or DME.

  Similarly, the pressurized gas supply means is a compressed air supply device connected to the pressurized gas introduction part via an air tube, and the pressurized gas introduction part is detachably connected to the air tube so that air can be supplied. It is preferable to have an air connection port part for this purpose.

  According to this configuration, the compressed air can be stably supplied at a constant pressure into the adhesive reservoir, and the reliability of the injection work can be ensured. In addition, it is preferable that the compressed air supply apparatus in this case is composed of a small compressor and a surge tank.

  On the other hand, the adhesive injection part has a nozzle part for injecting the adhesive while sealing the opening in the insertion hole, and an injection part main body to which the nozzle part is detachably attached and has an on-off valve mechanism. It is preferable.

  Hereinafter, an adhesive injection device and a pinning method using the same according to an embodiment of the present invention will be described with reference to the accompanying drawings. The pinning method uses an adhesive injection device to inject adhesive into an insertion hole that is drilled in the outer wall of a building where “floating” has occurred, or an interior wall such as a blowout or a hole that requires repair. Repair is performed by inserting pins. Hereinafter, the description will be given by taking as an example the case of repairing the outer wall (wall body) of an existing building.

FIG. 1 is a schematic view of a state in which an adhesive injection device is used on the outer wall. As shown in the figure, the outer wall 1 is applied through a concrete skeleton 2 which is a structure of a building, a base mortar 3 applied to the surface of the concrete skeleton 2, and a mortar 4 attached to the surface of the base mortar 3. And a plurality of tiles 5 (finishing material). Here, due to secular change, floating portions 6 (gap) are generated between the concrete frame 2 and the base mortar 3, between the base mortar 3 and the pasting mortar 4, and between the pasting mortar 4 and the tile 5. Shall. In such an outer wall 1, the tile 5 (and these mortars 3 and 4) may be peeled off from the concrete housing 2 due to the floating portion 6.
Therefore, the insertion hole 7 is formed in the outer wall 1, the adhesive R is injected into the insertion hole 7 by the adhesive injection device 10, and the tile 5 is put into the concrete frame 2 through the injected adhesive R. I try to anchor.

  FIG. 2 shows an adhesive injection device 10 for injecting the adhesive R. As shown in the figure, the adhesive injection device 10 includes an adhesive reservoir 11 for storing the adhesive R, and an adhesive flow path 13 communicating with the adhesive reservoir 11, and the insertion hole 7 The cylinder is connected to an adhesive injection section 12 for injecting the adhesive R into the adhesive reservoir section 11 and a gas cylinder 15 for supplying the adhesive R to the adhesive injection section 12 with a predetermined gas pressure. And a connection port portion 14. The adhesive R is enclosed in a tubular container and provided as a resin tube 16 and is attached to the adhesive reservoir 11. As the adhesive R, it is preferable to use various organic adhesives such as a two-pack type epoxy resin adhesive or an inorganic adhesive having an appropriate viscosity.

As shown in FIG. 2 and FIG. 3, the adhesive injection part 12 includes a nozzle part 21 for injecting an adhesive while sealing the opening 7 a in the insertion hole 7, and the nozzle part 21 is detachably mounted. And an injection part main body 22 having an on-off valve mechanism 23.

The adhesive R delivered from the injection unit main body 22 flows from the joint cylinder 31 to the nozzle 32 and is discharged from the tip of the nozzle 32. Further, the protruding dimension of the nozzle 32 with respect to the seal member 34 is adjusted by sliding the slide cylinder 33 with respect to the joint cylinder 31 and fixing the slide cylinder 33 to the joint cylinder 31 with the fixing lever 35.

  The joint cylinder 31 and the nozzle 32 are provided with an injection flow path 36 that constitutes the nozzle section 21 side of the adhesive flow path 13. The joint cylinder 31 and the nozzle 32 may be formed integrally. The slide cylinder 33 is slidably attached to the joint cylinder 31 with a predetermined dimensional tolerance. When the slide cylinder 33 is moved forward with respect to the joint cylinder 31, the protruding dimension of the nozzle 32 provided at the tip of the joint cylinder 31 becomes relatively short, and when the slide cylinder 33 moves backward, the protruding dimension of the nozzle 32 becomes relatively long. That is, the injection depth of the adhesive R is adjusted by moving the slide cylinder 33 back and forth with the seal member 34 being applied to the opening 7a of the insertion hole 7.

  The seal member 34 is made of a solvent-resistant elastic material with respect to the adhesive R, and has a tapered portion 34a having a tapered shape on the distal end side. The adhesive R is injected in a state where the opening 7a of the insertion hole 7 is sealed by the tapered portion 34a. The fixing lever 35 is formed in an “L” shape and has a hexagon wrench shape. By screwing the fixing lever 35, the tip thereof comes into contact with the joint cylinder 31, and the slide cylinder 33 is fixed to the joint cylinder 31 at an arbitrary slide position.

  The injection part main body 22 has a supply flow path 42 constituting the injection part main body 22 side of the adhesive flow path 13 and an on-off valve mechanism 23 for opening and closing the supply flow path 42 inside the main body housing 41. A front grip 43 is provided on the outside. The on-off valve mechanism 23 has a high-viscosity fluid on-off valve 45 built in the main body housing 41 and an on-off lever 46 for opening and closing the on-off valve 45. By operating the opening / closing lever 46 to “open”, the adhesive R in the adhesive reservoir 11 is supplied from the supply flow path 42 to the injection flow path 36 of the nozzle portion 21, and by performing “close” operation, the adhesive R Supply from the supply flow path 42 to the injection flow path 36 is blocked. The front grip portion 43 is provided so as to be horizontal with respect to the adhesive pouring device 10 in the pouring posture, while the open / close lever 46 is disposed at a position where it escapes from the front grip portion 43 so as not to hinder the operation. It is installed. The on-off valve 45 is preferably a cock type (ball valve) having a simple structure in consideration of cleaning.

  FIG. 4 shows a modification of the on-off valve mechanism 23. The on-off valve mechanism 23 according to the modified example includes a trigger lever 51 rotatably provided on the front grip portion 43 in addition to the on-off valve 45 and the on-off lever 46, and a connection for connecting the trigger lever 51 and the on-off lever 46. A link 52 and a return spring 53 engaged with the trigger lever 51 are further provided. When the trigger lever 51 is pulled against the return spring 53 with the front grip 43 held, the opening / closing lever 46 is “opened” via the connecting link 52. On the other hand, when the trigger lever 51 is returned by the return spring 53, the opening / closing lever 46 is “closed” via the connecting link 52. Thus, in the on-off valve mechanism 23 according to the modified example, it is possible to operate while holding the front grip portion 43.

  As shown in FIG. 2, the adhesive reservoir 13 communicates with the upstream end of the adhesive flow path 13 (supply flow path 42), and the tube connection in which the resin tube 16 enclosing the adhesive R is detachably connected. A casing 62 that covers the connected resin tube 16 in an airtight manner; and a rear grip 63 that is attached to the rear end of the casing 62. The casing 62 includes a casing base part 64 to which the tube connecting part 61 and the injection part main body 22 are attached, and a casing cylinder part 65 that is detachably and airtightly attached to the casing base part 64 and encloses the resin tube 16. ,have. And the casing base part 64 and the main body housing 41 of the injection | pouring part main body 22 are integrally formed (refer FIG. 3). The casing base portion 64 and the main body housing 41 may be separated and joined with screws or the like.

  The casing base portion 64 is formed in a somewhat thick flange shape with respect to the casing tube portion 65. A body housing 41 is integrally formed on the injection base body 22 side of the casing base portion 64 on the same axis, and a tube connection portion 61 and a casing cylinder portion 65 are coaxially screwed on the casing tube portion 65 side. A female screw portion 67 is integrally formed (see FIG. 3). The tube connection part 61 is formed with a connection flow path 68 that is continuous with the supply flow path 42 and is formed with a female thread part 69 that faces the connection flow path 68 and into which the resin tube 16 is screwed. By screwing the supply port of the resin tube 16 into the tube connection portion 61, the inside (adhesive) of the resin tube 16 communicates with the connection flow path 68 and the adhesive flow path 13, and the insertion hole 7 for the adhesive R is inserted. Can be injected.

  The casing cylinder part 65 has a cylinder part main body 71 that accommodates the resin tube 16, and a flange-shaped rear end closing part 72 that is provided so as to close the rear end of the cylinder part main body 71. Further, a rear grip portion 63 (trigger grip) having a substantially downward “L” shape is attached to the outside of the rear end closing portion 72. The operator holds the front grip part 43 and the rear grip part 63 with his / her left and right hands and holds the adhesive injection device 10 to carry out the work. In addition, the cylinder part main body 71 and the rear-end obstruction | occlusion part 72 may be formed integrally, and may be formed separately. However, when forming separately, it is set as the joining form which can maintain airtightness.

  On the other hand, on the outer peripheral surface of the front end portion of the cylindrical portion main body 71, an annular male screw portion 73 that is screwed into the annular female screw portion 67 of the casing base portion 64 is formed, and the annular male screw portion 73 is screwed into the annular female screw portion 73. By doing so, the casing cylinder part 65 is attached to the casing base part 64. Although not particularly illustrated, a seal ring (O-ring) is provided at a front end abutting portion of the casing tube portion 65 with respect to the casing base portion 64, and when the casing tube portion 65 is attached to the casing base portion 64, the adhesive storage portion 11. The inside is hermetically sealed. When the used resin tube 16 is replaced with a new resin tube 16 and when the injection portion main body 22 is washed, the casing cylinder portion 65 is removed from the casing base portion 64 and these operations are performed.

  As shown in FIG. 2, the cylinder connection port portion 14 to which the gas cylinder 15 is connected is provided on the outer peripheral surface (the lower surface) of the rear portion of the casing cylinder portion 65 in the adhesive reservoir 11. The gas cylinder 15 which is a pressure vessel is a so-called disposable cylinder (cassette cylinder), in which pressurized gas is enclosed to supply the adhesive R to the adhesive injection part 12 with a predetermined gas pressure. Yes. The gas cylinder 15 includes a stem 75 that discharges pressurized gas when pushed in, and a stem holder 76 that holds the stem 75 in a slidable manner and has an external thread formed on the outer peripheral surface thereof. The mouth portion 14 is detachably attached. As the pressurized gas, vaporized gas such as gas nitrogen or carbon dioxide, or liquefied gas such as LPG, chlorofluorocarbon, halon, or DME is used. The vaporized gas is mainly pressure-adjusted from a pressure adjusting valve (not shown), and the liquefied gas is pressure-adjusted mainly by adjusting the components of the gas to be mixed.

  The cylinder connection port portion 14 includes a cylinder mounting portion 78 into which the stem holder 76 of the gas cylinder 15 is screwed, and a stem pressing portion 79 that is connected to the cylinder mounting portion 78 and relatively presses the stem 75. A portion 79 communicates with the adhesive reservoir 11. When the gas cylinder 15 is rotated and the stem holder 76 is screwed into the cylinder mounting portion 78, the stem 75 is relatively pushed by the stem pressing portion 79, and the pressurized gas in the gas cylinder 15 is supplied to the adhesive reservoir 11.

  By the way, when exchanging the resin tube 16, it is necessary to remove the casing cylinder portion 65 from the casing base portion 64 as described above. In such a case, it is necessary to stop the supply of the pressurized gas from the gas cylinder 15 once. That is, it is necessary to remove the gas cylinder 15 from the adhesive reservoir 11. Although not particularly illustrated, it is preferable to provide an open / close valve for pressurized gas between the cylinder connection port portion 14 and the casing tube portion 65 in order to omit this operation. Alternatively, it is preferable to incorporate an on-off valve for pressurized gas into the cylinder connection port portion 14.

Next, with reference to FIG. 5 and FIG. 6, the pinning method to the outer wall 1 using said adhesive agent injection apparatus 10 is demonstrated according to a construction procedure.
This pinning method includes a keying process for determining the drilling position (floating portion) of the insertion hole 7 by keying the outer wall 1, a drilling process for drilling the insertion hole 7 at the determined drilling position of the outer wall 1, and an adhesive. Using the injection device 10, an adhesive injection step of injecting the adhesive R into the insertion hole 7, and an insertion step of inserting the anchor pin 81 into the insertion hole 7 into which the adhesive R has been injected, I have.

  In the keying process, the outer wall 1 is keyed using a hammer 82 or the like (see FIG. 5 (a)), and the portion to be repaired of the outer wall 1, that is, the floating between the concrete frame 2 and the base mortar 3 is based on the keying sound. Part 6 (first floating part 6a), floating part 6 (second floating part 6b) between the base mortar 3 and the pasting mortar 4, floating part 6 (third floating part) between the pasting mortar 4 and the tile 5 6c) is searched and the drilling position (usually a plurality) of the insertion hole 7 is determined. Following this, marking is appropriately performed at the drilling position (the center position of each tile 5). When a plurality of drilling positions are determined, the insertion hole 7 is drilled for diagnosis at the central drilling position, and the depth of the insertion hole 7 and the position of each floating portion 6 ( It is preferable to measure the depth position from the opening 7a) and the floating width of each floating portion 6.

  In the drilling step, the insertion holes 7 are formed at each drilling position of the marked outer wall using a drilling tool 83 such as an electric drill equipped with a diamond core drill 84. That is, the insertion hole 7 is formed by penetrating the concrete casing 2 to a predetermined depth through the tile 5, the mortar 4 and the base mortar 3 (see FIG. 5B). At that time, the outer wall 1 is perforated at a right angle, and the perforation depth of the concrete frame 2 is 30 mm or more. The insertion hole 7 is a straight hole having a diameter (1 mm to 2 mm thick) that is slightly larger than the anchor pin 81 so that the anchor pin 81 can be loosely fitted. The drilling tool 83 is preferably a wet low-noise drill using a coolant.

  In the adhesive injection step, the resin tube 16 is attached to the adhesive injection device 10 and the gas cylinder 15 is attached in advance. Further, before the gas cylinder 15 is mounted, the on-off valve 45 of the on-off valve mechanism 23 is set to “closed”. First, after adjusting the protruding dimension of the nozzle 32 from the measurement result of the insertion hole 7, the nozzle 32 is inserted into the insertion hole 7. Here, in a state where the opening 7 a is sealed by the seal member 34, the opening / closing lever 46 of the injection body 22 is operated to inject the adhesive R.

  In this injection operation, first, the protruding dimension of the nozzle 32 is adjusted so that the tip reaches the bottom of the insertion hole 7, and the adhesive R is injected into the deepest portion of the insertion hole 7 (see FIG. 5C). ). Next, while maintaining the pouring posture of the adhesive pouring device 10, the projecting dimension of the nozzle 32 is adjusted so that the tip is positioned at the first floating portion 6a, and the opening / closing lever 46 is "opened" to perform the first operation. An adhesive R is injected into the floating portion 6a (see FIG. 6D). The injected adhesive R spreads in the radial direction at the first floating portion 6a and reaches the first floating portion 6a. When the pressure on the insertion hole 7 side and the pressure on the adhesive injection device 10 side compete with each other and the injection stops, the operator performs a “close” operation on the opening / closing lever 46. In this manner, the adjustment of the protruding dimension of the nozzle 32 and the operation of the opening / closing lever 46 are repeated, and the adhesive R is injected into the subsequent second floating portion 6b and the third floating portion 6c (FIG. 6 (e)). )reference).

  In the insertion step, the anchor pin 81 is inserted into the insertion hole 7 into which the adhesive R has been injected while maintaining the horizontal posture (see FIG. 6F). In this case, as the anchor pin 81, for example, a so-called all screw pin having a head portion 86 whose surface is colored according to the color of the tile 5 and a shaft portion 87 which is continuous with the head portion 86 and has a male screw formed on the peripheral surface thereof is used. . The head portion 86 of the anchor pin 81 has a flat plate portion (0.3 to 0.5 mm thick) that is slightly larger in diameter than the opening of the insertion hole, and a tapered portion that reinforces the flat plate portion. It is assumed that the tile 5 can be pressed at the back edge. Alternatively, it is assumed that the head 86 has a truncated conical dish shape and the tile 5 can be pressed by the tapered portion. In this case, however, the dish is fried on the opening 7a.

  When the anchor pin 81 is pushed into the insertion hole 7, the adhesive R is pushed away, and the adhesive R spreads over the entire insertion hole 7. Finally, the anchor pin 81 is pushed in so that the surface of the head 86 and the surface of the tile 5 are flush with each other, and the operation is completed.

  As described above, according to the first embodiment, the operator only applies the nozzle portion 21 to the insertion hole 7 so as to seal the opening 7a, and “opens” the on-off valve mechanism 23. The adhesive R can be injected into the insertion hole 7. Further, when the insertion hole 7 and the floating portion 6 connected thereto are filled with the adhesive R, the pressure in the sealed insertion hole 7 and the gas pressure are balanced and the injection of the adhesive R is not performed. It is possible to prevent the injection amount of the adhesive R from becoming insufficient or excessive (peeling off the floating portion 6). Therefore, the injection | pouring operation | work of the adhesive agent R to the insertion hole 7 can be performed easily and reliably, without requiring skill.

  The pressure supply of the adhesive R may be performed using a piston. That is, the casing 62 (casing cylinder portion 65) is partitioned by a piston, the adhesive R is stored (filled) in the front space of the piston, and pressurized gas is introduced into the back side of the piston.

Next, with reference to FIG. 7, about the adhesive injection apparatus 10A which concerns on 2nd Embodiment, a different part from 1st Embodiment is mainly demonstrated.
In this adhesive injection device 10A, the injection part main body 22 of the adhesive injection part 12 is not provided with the on-off valve mechanism 23. Instead, a gas flow path for pressurized gas is provided in the cylinder connection port part 14. A gas on-off valve mechanism 91 that opens and closes 92 is provided. The gas on-off valve mechanism 91 has a gas on-off valve 93 interposed between the cylinder connection port portion 14 and the casing cylinder portion 65, and a gas on-off lever 94 for opening and closing the gas on-off valve 93. The gas opening / closing lever 94 extends toward the rear grip part 63 and can be operated with a finger that grips the rear grip part 63.

  By operating the gas opening / closing lever 94 to “open”, pressurized gas is supplied from the gas cylinder 15 to the adhesive reservoir 11, and by performing “close” operation, the supply of pressurized gas is shut off. When the pressurized gas is supplied to the adhesive storage part 11, the resin tube 16 is compressed and the adhesive R is supplied to the adhesive injection part 12. The gas on-off valve 93 may be integrated into the cylinder connection port portion 14. It is also preferable that the gas on-off valve 93 is constituted by a three-way valve, and the adhesive reservoir 11 is opened to the atmosphere at the same time as the supply of the pressurized gas is shut off by the “close” operation. In this case, it is possible to prevent the adhesive R from dripping from the tip of the nozzle 32.

  As described above, according to the second embodiment, it is possible to inject the adhesive R into the insertion hole 7 only by operating the gas on-off valve mechanism 91. The operation of injecting the adhesive R into the filling hole 7 can be performed easily and reliably without requiring skill. In addition, when replacing the resin tube 16, it is not necessary to remove the gas cylinder 15 from the adhesive reservoir 11, and the handleability can be improved.
