Description

  The present invention relates to a fluidity repair material injector for injecting a fluidity repair material to a repair target such as a crack generated in a concrete structure or a wall, for example.

  When repairing a crack that has progressed to the inside in a concrete structure or the like, in order to spread a fluid repair material such as an adhesive from the crack opening on the outer surface to the interior, the fluid repair material is injected under a predetermined pressure. There is a need.

  For such an adhesive injection operation, an injector 100A as shown in Patent Document 1 is used. Specifically, as shown in FIG. 10, the injector 100 </ b> A is a cylinder whose tip is attached so as to close the opening of the crack AO to be repaired, and whose proximal end is connected to a grease gun or the like that is a supply source of the adhesive L And a pressure accumulating mechanism TN that is branched from the injection mechanism IN. The pressure accumulating mechanism TN includes a sealed hollow cylinder 4A having a substantially hollow cylindrical shape, and a disc-like shape provided inside the cylinder 4A so as to be slidable from the proximal end to the distal end. The piston 5A is composed of a spring BN provided between the tip of the cylinder 4A and the piston 5A.

  When a grease gun is connected to such an injector 100A and the adhesive L is injected, a part of the adhesive L flows into the cylinder 4A, and the piston 5A moves from the proximal end side to the distal end side of the cylinder 4A. The gas G in the space between the piston 5A and the tip of the cylinder 4A and the spring BN are compressed.

  When the grease gun is removed from the injection mechanism IN and there is no force to press the adhesive L toward the crack AO side, the adhesive L that has become high pressure inside the crack AO tries to flow backward and exit to the outside. The adhesive L is pressed into the crack AO by the restoring force that the gas G and the spring BN compressed in the mechanism TN return to the original state.

  Thus, it is considered that the pressure accumulation mechanism TN prevents the backflow of the adhesive L from the crack AO when the grease gun is removed, and the adhesive L can be sufficiently distributed throughout the crack AO. ing.

  However, in the case described above, since the pressure applied to the adhesive L from the pressure accumulation mechanism TN is too weak, there may be a problem that the adhesive L is not sufficiently distributed in the crack AO.

  More specifically, the pressure to be applied to the adhesive L from the pressure accumulating mechanism TN differs depending on the internal size of the crack AO, the difference in viscosity depending on the type of the adhesive L, and the like. In 100A, since the volume of the cylinder 4A and the elasticity of the spring BN are fixed, the pressure at which the pressure accumulating container TN presses the adhesive L greatly deviates from the pressure suitable for the injection of the adhesive L. L injection may not be successful.

  Further, since the pressure accumulation mechanism TN described in Patent Document 1 cannot be divided from the sealed injection mechanism IN as shown in FIG. 10, a spring according to the repair situation and the adhesive L used. It is also difficult to adjust the pressure restoring mechanism TN so that the restoring force from the pressure accumulating mechanism TN is increased by replacing BN so as to be suitable for the injection of the adhesive L.

Japanese Patent Laid-Open No. 4-46026

  The present invention has been made in view of the above-described problems, has a simple structure, and easily restores the restoring force applied to the fluid repair material such as an adhesive from the pressure accumulation mechanism to that suitable for injection. It is an object of the present invention to provide a fluidity repair material injector that can be adjusted and can spread the fluidity repair material throughout the repair target.

  That is, in the fluidity repair material injector of the present invention, the connection port connected to the fluidity repair material supply source is formed at the base end as in the invention described in claim 1, and is opposed to the repair object. An injection mechanism that is attached and injects a fluid repair material into the repair target is formed at the tip, and the injection mechanism branches off from between the connection port and the injection port. A pressure accumulating mechanism in which a part of the fluidity repairing material flows and compresses an internal gas at the time of injection, and the pressure accumulating mechanism includes a hollow container having a proximal end provided in the injection mechanism and an open end; and A partition member provided in the hollow container so as to be slidable between the proximal end and the distal end thereof, and a lid for hermetically sealing the distal end of the hollow container, Take the sample inside the hollow container so that it protrudes from the tip to the base side. It can be attached and said.

  If it is such, the said cover body is divided | segmented into the said hollow container and the said cover body at least, and the said cover body is attached in the state protruded from the front-end | tip side in the inside of the said hollow container. Therefore, the gas existing between the partition member and the lid in the hollow container can be in a compressed state in advance.

  Accordingly, not only the restoring force stored by the fluid repair material flowing into the hollow container at the time of injection and the partition member moving to the distal end side of the hollow container and the gas in the hollow container being compressed. In addition, the restoring force corresponding to the compression of the gas is also added to the fluid repair material. For this reason, it is possible to increase the pressure to advance the fluidity repair material from the pressure accumulation mechanism to the repair target, and even when the fluidity repair material supply source is removed from the injection mechanism, While preventing backflow of the fluidity repair material, the fluidity repair material can be spread throughout.

  Also, by adjusting the amount of protrusion from the tip of the lid in the hollow container, the amount of gas compressed in the hollow container can be adjusted in advance, so that the size of the object to be repaired, the type of adhesive, etc. The pressure accumulating mechanism can also press the fluid repair material against the repair target with a corresponding pressure.

  When the pressure that presses the fluidity repair material from the pressure accumulation mechanism is too strong, the pressure of the gas in the hollow container is lowered to prevent problems such as the injection mechanism being removed from the repair target. In order to do so, it is only necessary that the pressure accumulating mechanism is configured to be able to release the gas between the partition member and the lid in the hollow container as in the invention described in claim 2.

  When the pressure for pressing the fluid repair material from the pressure accumulation mechanism is too weak, the gas pressure in the hollow container is increased so that a sufficient amount of fluid repair material can be injected into the repair target. As in the third aspect of the present invention, the pressure accumulating mechanism may be configured such that gas can be injected from the outside between the partition member and the lid in the hollow container.

  As a specific configuration for enabling the pressure of the gas in the hollow container to be adjusted as appropriate, and for achieving a pressure suitable for always injecting the fluid repair material, the invention according to claim 4 As described above, the lid body is inserted into the hollow container from the distal end to the proximal end side, and includes a cap formed with a through hole penetrating in the insertion direction, and a pneumatic pressure regulating valve inserted into the through hole. Can be mentioned.

  After using the fluidity repair material injector once, it may be reused by removing the fluidity repair material remaining in the hollow container, but when reused by removing incomplete fluidity repair material Problems may occur in the finish. In order to prevent the fluidity repair material injector from being reused in order to prevent the incomplete fluidity repair material from being injected into the repair object, as in the invention according to claim 5, It is only necessary that a fit-in structure is formed between the lid and the hollow container. If it is such, in order to remove the fluid repair material remaining in the hollow container for reuse, the lid or the hollow container can only be broken. That is, since the function of the pressure accumulating mechanism is lost and cannot be reused in the first place, it is possible to prevent incomplete injection into the repair target due to the use of the old fluidity repair material.

  In order to prevent the fluidity repair material from leaking from the connection port due to the backflow from the repair object when the fluidity repair material supply source is removed from the injection mechanism, the surroundings are not contaminated. As in the invention described in claim 6, the injection mechanism has a cylindrical shape in which the injection port is formed, a washer attached to the repair target, a tip attached to the washer, and the hollow container connected to a side surface What is necessary is just to be comprised from the main body and the non-return valve which is inserted in the base end side of the said cylindrical main body, and forms the said connection port.

  The pressure applied from the fluidity repair material supply source can be transmitted without waste to the fluidity repair material that progresses into the repair target, and the injection operation can be efficiently performed. It is only necessary that the connection port, the cylindrical main body, and the central axis of the injection port be arranged in a straight line as in the present invention.

  The fluid repair material is efficiently injected from the injection mechanism into the object to be repaired, and a part of the fluid repair material appropriately flows into the pressure accumulating mechanism so that the gas in the hollow container is sufficiently compressed. As in the invention described in claim 8, a communication hole for communicating between the cylindrical main body and the hollow container may be provided in the vicinity of the connection port.

  To reduce the amount of protrusion from the repair target in a state where the fluid repair material injector is attached to the repair target, and to make the compact and easy to perform the injection work, as in the invention according to claim 9. The hollow container is provided so as to be orthogonal to the cylindrical main body, and when viewed from the repair target, the base end of the cylindrical main body and the side surface of the hollow container on the anti-repair target side are substantially the same. It should be at height.

  As described above, according to the fluidity repair material injector of the present invention, the hollow container and the lid constituting the pressure accumulating mechanism are separated from each other, and the lid is inside the hollow container. Since it is made to project from the distal end to the proximal end side, the gas in the hollow container can be compressed in advance before the start of the injection operation. Therefore, in addition to the restoring force due to the compression of the gas in the hollow container by the movement of the partition member at the time of injection, it is possible to add a restoring force for the portion that has been further compressed to the fluidity repair material, It becomes possible to spread the fluidity repair material throughout the repair target.

  A fluidity repair material injector according to an embodiment of the present invention will be described with reference to the drawings.

  The fluidity repair material injector of the present embodiment is an adhesive injection used for repair work in which an adhesive L is injected as a fluidity repair material into a crack AO that is a repair target generated in a concrete structure C or the like in civil engineering work or the like. Device 100. More specifically, as shown in the perspective view of FIG. 1, the adhesive injector 100 is fixed to a portion where the crack AO is opened on the outer surface of the concrete structure C. Mediates a certain grease cancer SP. The parts constituting the adhesive injector 100 are made of resin without using metal, and can be discarded without being separated after use.

  The adhesive injector 100 is a part that is vertically attached to the concrete structure C or the like to be repaired, and includes an injection mechanism IN through which the adhesive L flows from the grease gun SP to the crack AO, and the injection mechanism IN. It is provided so as to be branched so as to be orthogonal to the part, and when the adhesive L is injected by the grease gun SP, a part of the adhesive L flows into the inside and the gas G inside is compressed. The pressure accumulating mechanism TN.

  As shown in the perspective view of FIG. 1, the injection mechanism IN is a thin cylindrical part in the adhesive injector 100, and a connection port CP connected to a grease gun SP as an adhesive supply source is formed at the base end. In addition, an injection port IP is formed at the tip so as to be opposed to the crack AO and injecting the adhesive L into the crack AO.

  More specifically, as shown in the exploded view of FIG. 2, the injection mechanism IN has the injection port IP formed therein, a washer 1 attached to a concrete structure C having a crack AO, and a tip of the washer. 1 and includes a cylindrical body 2 having a hollow container 4 connected to a side surface thereof, and a check valve 3 that is inserted on the proximal end side of the cylindrical body 2 and forms the connection port CP. It is.

  The washer 1 includes a thin disc portion 11 having the injection port IP opened at a central portion, and a cylindrical portion 12 surrounding the injection port IP and projecting perpendicularly to the upper surface of the thin disc portion 11. The outer peripheral portion of the lower surface of the thin disc portion 11 is fixed by being adhered to the surrounding wall surface where the crack AO is opened by the fixing material F. This fixing material F shows a strong viscosity in the compression or pulling direction, but shows a weak viscosity in the shearing direction. Therefore, when removing the adhesive injector 100 after injecting the adhesive L into the crack AO, It can be easily removed by moving in the direction along the surface of the wall. The cylindrical portion 12 is hollow, and a female screw 12A that is screwed into the cylindrical main body 2 is cut inside. The washer 1 has the same configuration as the conventional product.

  As shown in FIG. 2, the cylindrical main body 2 has a hollow cylindrical shape that is thinner than the cylindrical portion 12. The check valve 3 is accommodated in the base end without any gap, and the outer peripheral surface at the tip thereof is A male screw 21 that engages with the cylindrical portion 12 is cut. Further, as shown in the cross-sectional view of FIG. 2B, the cylindrical main body 2 is a central portion of the side surface thereof and communicates with the inside of the pressure accumulating mechanism TN in the vicinity of the tip in a state where the check valve 3 is accommodated. A communication hole 22 is formed.

  When the grease gun SP is inserted, the tip of the check valve 3 opens, and the adhesive L circulates into the cylindrical main body 2. However, when the grease gun SP is removed, the cutting of the tip is closed, The adhesive L in the cylindrical main body 2 is configured not to flow out from the connection port CP. This check valve 3 is formed of a flexible resin such as an elastomer, and the grease gun SP does not completely match the axial direction of the cylindrical body 2 and can be connected even in a slightly inclined state. The ease of connection is improved.

  Further, the washer 1, the cylindrical main body 2, and the check valve 3 that constitute the injection mechanism IN are configured such that their respective central axes coincide with each other on a straight line. When the adhesive L is pushed out from the grease gun SP connected to the head toward the crack AO, the force can be transmitted with almost no loss. Therefore, even if there is a portion blocked by dust or sand particles in the crack AO, the adhesive L can be spread throughout the crack AO while being blown by the pressure of the adhesive L.

  Next, the pressure accumulation mechanism TN will be described.

  The pressure accumulating mechanism TN corresponds to a thick cylindrical portion in the adhesive injector 100 as shown in FIG. 1, and a hollow container 4 whose proximal end is attached to the injection mechanism IN and whose distal end is open, A partition member 5 provided in the hollow container 4 so as to be slidable without any gap between its proximal end and distal end, and a lid 6 for hermetically sealing the distal end of the hollow container 4. is there. That is, the pressure accumulating mechanism TN is composed of two divided parts, the hollow container 4 and the lid body 6. The hollow container 4 is integrally formed as one part in a state where it is combined with the cylindrical main body 2. Further, the hollow container 4 is provided so as to be orthogonal to the cylindrical main body 2, and the base end of the cylindrical main body 2 and the side surface on the anti-crack side of the hollow container 4 as viewed from the crack AO are approximately. It should be at the same height.

  The hollow container 4 is a cylinder configured so that the inside thereof can be seen through with a transparent resin having a substantially hollow cylindrical shape. As shown in FIG. 2, the outer peripheral surface of the hollow container 4 is graduated from the proximal end side to the distal end side, and the amount of the adhesive L flowing into the hollow container 4 from the injection mechanism IN is reduced. I understand it.

  The partition member 5 is airtightly mated with the inner peripheral surface of the hollow container 4, and is a substantially flat solid cylindrical piston having substantially the same diameter as the inner diameter of the hollow container 4. The partition member 5 is attached so as to be in close contact with the proximal end of the hollow container 4 at the start of injection, and the injection of the adhesive L is started by the grease gun SP connected to the injection mechanism IN. When the adhesive L enters the hollow container 4, it moves to the tip side of the hollow container 4. As for the thickness of the partition member 5, when the adhesive L flows into the hollow container 4 from the communication hole 22 and is pushed, the partition member 5 does not fall down, and the flat plate portion is the hollow container 4. It is set so as to slide in the posture parallel to the radial cross section.

  The lid body 6 is attached in a state protruding from the distal end to the proximal end side by a predetermined length inside the hollow container 4. The lid body 6 has a check valve function, and the gas G in the hollow container 4 is discharged to the outside via the lid body 6 to release the pressure, or the gas into the hollow container 4 is released. G can be injected and pressurized.

  More specifically, as shown in the exploded view of FIG. 2, the lid body 6 is inserted into the hollow container 4 from the distal end to the proximal end side, and a cap 61 in which a through hole 61H penetrating in the insertion direction is formed. And an air pressure adjusting valve 62 inserted into the through hole 61H.

  The cap 61 is formed in a thin annular shape having substantially the same size as the outer diameter of the hollow container 4 so that the base end portion engages with the distal end of the hollow container 4. The distal end side inserted into the rim is formed in a substantially cylindrical shape having an outer diameter slightly smaller than the inner diameter of the hollow container 4. The tip of the cap 61 is covered with a part of the air pressure adjusting valve 62 so as to be airtightly coupled with the inner peripheral surface of the hollow container 4 without a gap. Further, a fitting structure 7 is formed between the outer peripheral surface of the cap 61 and the hollow container 4.

  The air pressure adjustment valve 62 is formed of a flexible resin such as an elastomer, has the same shape as the tip of the cap 61, and is attached to the cap 61 in the state of the hollow container 4. An airtight portion 62A having an outer diameter substantially the same as the inner diameter and a cylindrical valve portion 62B inserted into a through hole 61H formed in the center of the cap 61 are configured.

  Next, an assembly procedure of the adhesive injector 100 according to the present embodiment configured from such parts will be described with reference to FIG. The assembly procedure is as follows.

  1) After molding into the shape of the check valve 3 and the air pressure adjusting valve 62 with an elastomer, a check is made by cutting the tip of the check valve 3 and the tip of the valve portion 62B of the air pressure adjusting valve 62. Ensure that the valve functions. 2) Insert the check valve 3 into the proximal end of the cylindrical body 2. 3) The lid body 6 is formed by fitting the air pressure adjusting valve 62 into the tip of the cap 61 and the through hole 61H. 4) The partition member 5 is fitted into the proximal end on the cylindrical main body 2 side in the hollow container 4. 5) The lid 6 is fitted to the tip of the hollow container 4. At this time, the airtight portion 62A of the air pressure adjusting valve 62 is kept airtight while preventing the air inside the hollow container 4 from coming out of the lid body 6 so that the airtight portion 62A of the air pressure adjusting valve 62 does not come off the inner peripheral surface of the hollow container 4. While pushing in the inside. 6) Finally, the tip of the cylindrical main body 2 is screwed into the washer 1 attached to the concrete structure C, and the adhesive L injector 100 is completed.

  Here, the preload effect of the gas G in the hollow container 4 by attaching the lid 6 to the hollow container 4 will be described with reference to FIG.

  As shown in the above-mentioned procedure 4) and 5), the partition member 5 is disposed at the proximal end of the hollow container 4 in an airtight state inside the hollow container 4, and in this state, the tip of the hollow container 4 The lid body 6 is pushed toward the proximal end side. The lid body 6 is pushed toward the base end side while maintaining airtightness with the inner peripheral surface of the hollow container 4, so that the lid body 6 is located between the partition member 5 and the lid body 6 inside the hollow container 4. The gas G is compressed by the distance by which the tip portion of the lid 6 is pushed. That is, the adhesive L injector 100 is in a state before the injection is started, and the partition member 5 is moved to the proximal end side of the hollow container 4 even when the adhesive L is not contained in the hollow container 4. A force can be applied in the direction of travel. Therefore, the force for pushing the adhesive L from the pressure accumulating mechanism TN into the crack AO can be further increased by the preload effect.

  Next, operation | movement at the time of inject | pouring the adhesive agent L of the adhesive injection device 100 of this embodiment is demonstrated, referring FIG.

  As shown in FIG. 5, when the adhesive injector 100 is attached to the wall surface of the concrete structure C having a crack AO, the nozzle of the grease gun SP is inserted into the check valve 3, and the adhesive L is driven by the power of the grease gun SP. Is injected into the crack AO via the injection mechanism IN.

  As shown in FIG. 6, when a certain amount of adhesive L is injected into the crack AO and the resistance increases, a part of the adhesive L flows into the pressure accumulating mechanism TN. At this time, since the inside of the hollow container 4 is partitioned by the partition member 5, only the gas G exists on the distal end side in the hollow container 4, and the adhesive L is only on the proximal end side in the hollow container 4. It will be in a certain state. That is, the gas G sealed in the hollow container 4 does not leak into the adhesive L on the injection mechanism IN side because of the partition member 5. Therefore, no bubbles are generated in the adhesive L, and the adhesive L is hardened in a state where “soot” enters in the crack AO, thereby preventing an insufficient repair result.

  In addition, as shown in FIG. 6, the partition member 5 moves toward the distal end side due to the pressure of the adhesive L flowing into the hollow container 4, so that there is a gap between the partition member 5 and the lid body 6. The gas G is compressed. This state is maintained as long as force is applied by the grease gun SP so that the adhesive L advances to the crack AO side.

  As shown in FIG. 7, the grease gun SP is removed from the check valve 3 when the resistance from the crack AO increases and a sufficient amount of the adhesive L flows into the hollow container 4. When the pressure from the grease gun SP to the adhesive L is lost, the balance of the force in the partition member 5 is lost, and the compressed gas G in the hollow container 4 pushes the adhesive L through the partition member 5. Therefore, the partition member 5 moves from the distal end side to the proximal end side in the hollow container 4, and the adhesive L in the hollow container 4 is injected into the crack AO. The movement of the partition member 5 is continued up to a point where the pressure due to the resistance from the inside of the crack AO and the pressure of the gas G are balanced. Here, in this embodiment, since the gas G in the hollow container 4 is pre-pressurized when the lid 6 is attached, there is no adhesive L in the hollow container 4 and the volume of the gas G is in the initial state. Even if it is the same, the partition member 5 is pressed toward the proximal end side of the hollow container 4. Therefore, as shown in FIG. 7, the partition member 5 eventually moves to the proximal end of the hollow container 4 and almost all the adhesive L in the hollow container 4 can be injected into the crack AO. .

  Next, the decompression or pressurization of the gas G in the hollow container 4 by the air pressure adjusting valve 62 will be described with reference to FIG.

  As shown in FIG. 8 (a), the valve portion 62B of the air pressure adjusting valve 62 has a check valve structure. Therefore, by inserting a cylinder or the like into the valve portion 62B as shown in FIG. 8 (b). The gas G in the hollow container 4 can be discharged and decompressed. By such pressure release operation, the adhesive L flows into the hollow container 4 and the adhesive injector 100 is made into a concrete structure before the adhesive L is solidified even in the middle of the compression of the gas G in the hollow container 4. It can be removed from the wall of the object C. In addition, when the pressure from the said pressure accumulation mechanism TN to the adhesive agent L is too strong, it can also be set as the pressure suitable for injection | pouring by decompression. In the present embodiment, since the hollow container 4 includes the partition member 5 slidably provided between the communication hole 22 on the proximal end side and the air pressure adjusting valve 62 on the distal end side, Even when the pressure is released by the air pressure adjustment valve 62, the adhesive L is blocked by the partition member 5 in the hollow container 4 and does not reach the air pressure adjustment valve 62. Therefore, the adhesive L does not come out to the outside via the pneumatic pressure regulating valve 62 when the pressure is released, and the adhesive L can be prevented from being scattered and contaminated at the construction site. Etc. can keep clean.

  Further, when it is desired to inject the adhesive L before solidifying remaining in the hollow container 4 into another crack AO, the removed adhesive L injection container as shown in FIG. It is possible to inject the adhesive L into the crack AO by attaching to the AO, pressurizing the gas G in the hollow container 4 via the air pressure adjusting valve 62. In addition, when the pressure from the said pressure accumulation mechanism TN to the adhesive agent L is too weak, it can also be set as the pressure suitable for injection | pouring by pressurization.

  Thus, according to the adhesive injector 100 of the present embodiment, the partition member 5 is always in the state in which the gas G in the hollow container 4 is compressed in advance by attaching the lid 6 to the hollow container 4. A restoring force can be generated in the direction of proceeding toward the proximal end in the hollow container 4.

  Therefore, the adhesive L enters the hollow container 4 at the time of injection, and not only the restoring force generated when the gas G in the hollow container 4 is compressed by the movement of the partition member 5, but also the preload of the gas G Even when the grease gun SP is removed, the adhesive L in the hollow container 4 can be pressed into the crack AO by the restoring force generated by the above. For this reason, the pressure accumulation mechanism TN can apply a stronger pressure to the adhesive L than before, and can spread the adhesive L throughout the crack AO.

  Further, the pressure of the adhesive L injected from the grease gun SP is provided so as to close the communication hole 22 in a state in which the partition member 5 is preloaded at the proximal end of the hollow container 4 before the start of use. Does not escape to the hollow container 4 side. Therefore, since the pressure applied to the adhesive L from the grease gun SP is almost applied only to the crack AO, it is possible to further enhance the effect of blowing the pebbles clogged in the crack and spreading the adhesive L everywhere. is made of.

  Further, the pressure and pressure of the gas G in the hollow container 4 can be freely released and pressurized through the air pressure adjusting valve 62, so that the adhesive injector 100 can be removed or hollowed out in the middle of the injection operation. The adhesive L remaining in the container 4 can be injected into another crack AO. In addition, the pressure applied to the adhesive L by the pressure accumulation mechanism TN can always be adjusted to a pressure suitable for injection by pressure release and pressurization operations.

  Furthermore, since the partition member 5 is provided in the hollow container 4 in the adhesive injector 100 of the present embodiment, the gas G in the hollow container 4 may be mixed into the adhesive L to form bubbles. Absent. Therefore, the adhesive injector 100 of the present embodiment is shown in FIG. 9 (a) where the pressure accumulating mechanism TN had to be attached to the washer 1 so as to be vertically upward. Thus, the pressure accumulating mechanism TN can be attached in a free direction such as vertically downward. For this reason, handling at the repair site is very good and easy to use.

  Other embodiments of the present invention will be described.

  In the embodiment, the air pressure adjusting valve 62 is provided on the cap 61, but may be provided on the side surface of the hollow container 4, for example. Even in such a case, the decompression and pressurization operations can be performed. Moreover, in the said embodiment, although the said cover 6 was provided with the said air pressure adjustment valve 62, you may abbreviate | omit this function. What is necessary is just the shape which protruded to the inner side so that the gas G in the said hollow container 4 may be compressed when the said cover body 6 is attached to the front-end | tip of the said hollow container 4 at least. At that time, it is only necessary that the airtightness is maintained between the lid 6 and the hollow container 4. Furthermore, what is necessary is just to determine the length which makes the cover body 6 protrude in the hollow container 4 according to the amount of preload. For example, when the adhesive L having a high viscosity is injected into the crack AO, the amount of preload may be increased so that the adhesive L is injected deep into the crack AO.

  Instead of providing the air pressure adjusting valve 62, a pressure releasing structure only for pressure releasing may be formed in the lid body 6. For example, the decompression structure includes a decompression port formed in the lid body 6 and a sealing body that hermetically seals the decompression port, and the space between the decompression port and the sealing body. What is comprised so that it may peel when the joining of this applies a force in a predetermined direction may be used. More specifically, the decompression structure may be formed like a pull top formed in a can or the like. With such a configuration, although pressure cannot be applied, the pressure in the pressure accumulating mechanism TN can be released with a simple structure.

  The pressure accumulating mechanism TN is not provided orthogonal to the injection mechanism IN but may be attached obliquely. In short, what is necessary is just to provide the pressure accumulating mechanism TN by branching from the injection mechanism IN. Further, the shape of the hollow container 4 constituting the pressure accumulating mechanism TN is not limited to the cylindrical tube shape. For example, the hollow container 4 may have a two-stage cylindrical shape whose proximal end side is narrower than the distal end side. With such a configuration, the adhesive injector 100 itself can be made compact by shortening the length of the hollow container 4 projecting from the injection mechanism IN. In addition, since the volume of the air pushed into the hollow container 4 when the lid 6 is attached can be increased, the air in the hollow container 4 can be preloaded to the same level as or more than that in the above embodiment. Further, by forming a screw between the hollow container 4 and the lid body 5 and screwing the lid body 5 to the hollow container, the air in the hollow container 4 is preloaded. You may do it.

  In the embodiment, the repair target is a crack AO, but the present invention may be used for other repair targets. Moreover, although the adhesive L was mentioned as an example of a fluid repair material, the fluid repair material injector 100 of the present invention can be used for other materials such as a caulking material, for example. In addition, the fluidity repair material supply source is not limited to the grease gun SP, and the fluidity repair material may be injected into the repair target manually by, for example, a syringe.

  In the above embodiment, the hollow container 4 and the lid body 6 are configured so as not to be removed once attached by the fitting and closing structure 7, but may be configured to be removable.

  In the said embodiment, although the outer peripheral surface to which the hollow container 4 is attached in the cylindrical main body 2, and the surface of the partition member 5 facing the said outer peripheral surface were formed as a flat surface, adhesive L In order to make it easier for the partition member 5 to move in the hollow container 4 while maintaining the initial posture when it flows into the hollow container 4, an uneven structure is formed on each surface as shown in FIG. It may be formed.

  More specifically, a ring-shaped concave groove 23 is formed on the outer peripheral surface of the cylindrical main body 2 as the concave-convex structure so as to include the opening of the communication hole, and the ring-shaped groove engages with the concave groove 23. The protrusions 51 may be formed on the facing surface of the partition member 5. In this way, the adhesive L that has flowed into the hollow container 4 from the cylindrical body 2 through the communication hole 22 first flows to fill the gap between the bottom surface of the concave groove 23 and the protrusion 51. It is possible to prevent the adhesive L from being concentrated only on the inner surface of the hollow container and pressing only a part of the partition member 5. That is, since the ring-shaped adhesive L uniformly presses the opposing surface of the partition member 5 in the axial direction, the partition member 5 hardly falls down and smoothly slides in the hollow container 4. Can do.

  Further, as shown in FIG. 9 (b), the opening portion into which the check valve 3 of the cylindrical main body 2 is inserted is partially expanded outward to form an engaging step portion 23 having a step portion. After the base end side of the stop valve is engaged with the engagement step portion 23, the check valve 3 is attached so that the check valve 3 does not come off by pressing the opening portion in the axial direction of the cylindrical main body 2 while heating. May be. The distal end side opening 41 of the hollow container 4 may be formed in the same manner as the engagement step portion 23 and the lid body 6 may be attached. In this way, the check valve 3 and the lid body 6 can be attached in an airtight and non-removable manner without forming the fitting structure 7 or the like while having a simple structure.

  In addition, various modifications and combinations of embodiments may be performed without departing from the spirit of the present invention.
