Abstract

PROBLEM TO BE SOLVED: To provide a retainer capable of retaining a fluid adhesive introduced to a mounting hole having an opening facing downward, preventing the adhesive from flowing downward.SOLUTION: A retainer 10 is attached to a nozzle 5 of a cartridge 3 containing an adhesive. The nozzle 5 and the retainer 10 are inserted into a mounting hole 1b. Then, the adhesive 6 in the cartridge 3 is ejected from the nozzle 5 to inject the adhesive 6 into the interior of the mounting hole 1b above the retainer 10. The retainer 10 receives the adhesive 6. When the entirety of the mounting hole 1b above the retainer 10 is filled with the adhesive 6, the nozzle 5 is extracted from the retainer 10 and the mounting hole 1b. Then, an anchor bolt 2 is inserted into the mounting hole 1b, allowing the adhesive 6 that has been received by the retainer 10 to flow between a recessed portion (not shown) of the retainer 10 and an inner circumferential surface of the mounting hole 1b, flowing downward from the retainer 10. As a result, the adhesive 6 fills the entire space between the inner circumferential surface of the mounting hole 1b and an outer circumferential surface of the anchor bolt 2.

Description

  The present invention relates to a holder for an adhesive used when, for example, an adhesive such as an adhesive having fluidity is injected into a downward mounting hole.

  In general, when a new structure is to be attached to an existing concrete structure, a mounting hole is first formed in the concrete structure, and an adhesive (fixing agent) having fluidity such as cement paste is placed in the mounting hole. Inject only a fixed amount. Thereafter, an anchor bolt is inserted into the mounting hole. Then, the annular space between the inner peripheral surface of the mounting hole and the outer peripheral surface of the anchor bolt is filled with the adhesive. When this adhesive is solidified, the anchor bolt is fixed to the concrete structure. And a new structure is attached to the existing concrete structure using this anchor bolt.

  Conventionally, when an adhesive is injected into the mounting hole, a discharge gun as described in Patent Document 1 below has been used. The discharge gun has a discharge nozzle, and the discharge nozzle is inserted from the opening of the mounting hole toward the bottom. Thereafter, the adhesive is discharged from the discharge nozzle to inject the adhesive into the mounting hole.

JP2001-149848

  There are various types of mounting holes for injecting adhesive, such as those with the opening facing upward, those facing the horizontal direction, or those facing downward, but with the opening facing upward In the case of a mounting hole, the adhesive does not fall from the opening of the mounting hole during the injection. However, in the case of a mounting hole whose opening is directed horizontally or downward, particularly a mounting hole directed downward, the adhesive flows downward from the bottom side of the mounting hole and drops from the opening during the injection. There was a problem that.

In order to solve the above-described problem, the present invention holds the sticking agent that holds the sticking agent having fluidity injected into the mounting hole in which the opening is located at the same position or below in the vertical direction with respect to the bottom. The mounting hole has a main body part that can be inserted from the opening to the bottom side, a contact part is provided on the outer peripheral part of the main body part, and the main body part is provided at the center part of the main body part. An injection hole is provided through the hole in the longitudinal direction of the hole, and the body portion is provided with a semi-circulation portion that penetrates the body portion in the longitudinal direction of the hole. By pressing and contacting the peripheral surface, the main body portion is prevented from moving from the bottom side of the mounting hole to the opening side with a predetermined amount of force,
In the internal space of the mounting hole between the bottom of the mounting hole and the main body, the fixing agent is injected through the injection hole, and the semi-circulating portion acts on the lower end of the fixing agent. When the pressing force is less than or equal to a predetermined magnitude, the fixing agent is prevented from passing through the semi-circulating portion, and when the pressing force acting on the fixing agent is greater than or equal to a predetermined magnitude, the fixing agent is less than the half pressure. It is characterized by allowing passage through the distribution section.
In this case, the main body portion is formed of an elastically deformable metal plate, and the contact portion is pressed and contacted with the inner peripheral surface of the mounting hole by the elasticity of the main body portion and the contact portion itself. It is desirable that the main body is prevented from moving toward the opening of the mounting hole with a predetermined magnitude of force.
It is desirable that a plurality of the abutting portions are formed apart from each other in the circumferential direction of the main body portion, and the semi-circulation portion is formed between two abutting portions adjacent to each other in the circumferential direction of the main body portion.
The main body portion is formed as a flat plate orthogonal to the longitudinal direction of the mounting hole, and the contact portion is directed from the bottom side of the mounting hole toward the opening side as it goes from the inner side to the outer side of the main body portion. It is desirable to be inclined.

For example, in order to fix an anchor bolt in a downward mounting hole, when injecting a fluid adhesive (fixing agent) into the mounting hole using the fixing agent holder having the above-described configuration, first the mounting hole The holder is inserted to a predetermined position. The inserted holder stays at the insertion position when the contact portion presses and contacts the inner peripheral surface of the mounting hole. Thereafter, the adhesive is injected into the mounting hole above the holder from the injection hole. The injected adhesive is received by the holder. Then, an adhesive is filled in the mounting hole above the holder. In this state, the adhesive tends to move downward through the semi-circulating portion of the holder, but the semi-circulating portion prevents the adhesive from passing through the semi-circulating portion downward due to its own weight. Therefore, it is possible to prevent a situation in which the adhesive flows downward during the injection and falls from the opening of the mounting hole.
After the adhesive is filled in the mounting hole above the holder, the anchor bolt is inserted into the mounting hole from the opening. When the anchor bolt is inserted to a predetermined position, the anchor bolt hits the holder and pushes the holder upward. Then, since the pressure which acts on an adhesive agent increases, an adhesive agent moves to the opening part side of an attachment hole through the semi-circulation part of a holder. Therefore, the holder can move upward toward the bottom side j of the attachment hole, and the anchor bolt can be inserted into the attachment hole even after hitting the holder. The adhesive that has flowed downward through the semi-circulating portion fills the space between the outer peripheral surface of the anchor bolt and the inner peripheral surface of the mounting hole. When the anchor bolt is inserted to a predetermined position inside the mounting hole, almost the entire area between the outer peripheral surface of the anchor bolt and the inner peripheral surface of the mounting hole is filled with the adhesive. Then, the anchor bolt is fixed to the mounting hole by the adhesive solidifying.

The best mode for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 shows an example in which a holder for a sticking agent according to the present invention (hereinafter simply referred to as a holder) is used. On a lower surface 1a of a horizontal wall portion 1 such as a concrete floor slab, A mounting hole 1b extending upward is formed. The holder 10 according to the present invention is inserted into the mounting hole 1b. The holder 10 is located near the bottom surface of the mounting hole 1b, that is, at the upper end. Further, the base end portion (upper end portion) of the anchor bolt 2 is inserted into the mounting hole 1b. The anchor bolt 2 has an outer diameter that is smaller than the inner diameter of the mounting hole 1b by a predetermined dimension, and is arranged such that its axis coincides with the axis of the mounting hole 1b. As a result, an annular space 3 is formed between the inner peripheral surface of the mounting hole 1 b and the outer peripheral surface of the anchor bolt 2. The upper end surface of the anchor bolt 2 is brought into contact with the lower surface of the holder 10.

  Of the internal space of the mounting hole 1b, a portion excluding the space occupied by the holder 10 and the anchor bolt 2, that is, the internal space above the holder 1 and the annular space S is provided with an adhesive (such as concrete mortar). (Fixing agent) 6 is filled. The adhesive 6 is filled in the internal space of the mounting hole 1b in a state having fluidity. And the anchor bolt 2 is being fixed to the attachment hole 1b because the filled adhesive agent 6 solidifies.

  When the anchor bolt 2 is fixed to the mounting hole 1b, first, the mounting hole 1b is formed in the lower surface 1a of the wall 1 as shown in FIG. The mounting hole 1b can be formed using a drill or other drilling tool (not shown).

  Next, as shown in FIG. 3, the cartridge 3 is attached to a discharge device (not shown) such as a discharge gun. The cartridge 3 is filled with an adhesive 6 and is disposed with the discharge port 3a facing upward. The lower end portion of the connecting cylinder 4 is fitted and fixed to the outer periphery of the discharge port 3a. The lower end of the nozzle 5 is fitted and fixed to the upper end of the inner periphery of the connecting cylinder 4. A holder 10 according to the present invention is externally attached to the outer periphery of the nozzle 5 so as to be movable in the longitudinal direction of the nozzle 5. The holder 10 is placed on the upper end surface of the connecting cylinder 4. Thereby, the position of the holder 10, that is, the distance from the upper end surface of the nozzle 5 to the holder 10 is set to a desired distance.

  The holder 10 is made of a thin metal plate so that it can be elastically deformed. As shown in FIG. 8, the holder 10 has a main body 11. The main body 11 is formed as a flat plate orthogonal to the axis of the mounting hole 1b, and an injection hole 12 penetrating the main body 11 in the vertical direction is formed at the center. The inner diameter of the injection hole 12 is slightly larger than the outer diameter of the nozzle 5, but is smaller than the outer diameter of the connecting cylinder 4. Accordingly, the nozzle 5 can be inserted into the injection hole 12, but the connecting cylinder 4 cannot be inserted. When the nozzle 5 is inserted into the injection hole 12 to a predetermined position, the lower surface of the main body 11 is connected to the connecting cylinder 4. It hits the top surface of the. As a result, the holder 10 is supported by the upper end surface of the connecting cylinder 4.

  As shown in FIG. 8A, a plurality (four in this embodiment) of protruding portions 13 are formed on the outer peripheral portion of the main body portion 11. The protruding portion 13 is disposed on the same plane as the main body portion 11 and protrudes outward in the radial direction of the main body portion 11. The width of the projecting portion 13 becomes narrower toward the outer side in the radial direction of the main body portion 11, whereby the plan view shape of the projecting portion 13 (the shape seen from the axial direction of the mounting hole 1 b) is triangular. Yes.

  The front end portion of each protrusion 13 is bent downward, and the portion on the front end side from the bent portion is a contact portion 14. The contact part 14 is inclined so as to go downward as it goes outward in the radial direction of the main body part 11. As shown in FIG. 8A, the tip edge of each contact portion 14 is positioned outside the inner peripheral surface of the mounting hole 1b. That is, the diameter of the circle connecting the tip edges of the contact portions 14 is larger than the inner diameter of the mounting hole 1b. Therefore, when the holder 10 is inserted into the mounting hole 1b from the lower end opening, the main body 11 and the protrusion 13 are formed such that the tip of the contact portion 14 abuts against the lower surface 1a of the wall 1 and the inclination angle increases. And the contact part 14, especially the protrusion part 13 and the contact part 14 are elastically deformed greatly. As a result, the holder 10 can be inserted into the mounting hole 1b. Moreover, the protrusion 13 and the contact portion 14 are elastically deformed with a relatively small force so that the inclination angle of the contact portion 14 is increased. Therefore, the holder 10 can be easily inserted into the mounting hole 1b with a relatively small force. On the other hand, when the holder 10 is inserted into the mounting hole 1b, the angle formed by the inner peripheral surface of the mounting hole 1b and the contact portion 14 is an acute angle, so the holder 10 will be moved downward. Then, the situation where the contact portion 14 bites into the inner peripheral surface of the mounting hole 1b is exhibited. Therefore, the holder 10 does not move downward unless pressed down with a large force, and as shown in FIGS. 6 and 7, the adhesive is filled in the mounting hole 1 b above the holder 10. Even if done, the holder 10 does not move downward due to the weight of the filled adhesive 6.

  A triangular recess (semi-circulating portion) 15 is defined between the two projecting portions 13 and 13 adjacent to each other in the circumferential direction of the main body portion 11. The shape and size of the recess 15 in plan view are determined based on experiments as appropriate according to the fluidity (viscosity) of the adhesive 6 injected into the mounting hole 1b and the size of the particles. That is, as shown in FIGS. 6 and 7, in the state where the entire inside of the mounting hole 1 b located above the holder 10 (excluding the occupied space of the nozzle 5) is filled with the fluid adhesive 6. The adhesive 6 tries to pass through the recess 15 by its own weight. However, the size of the recess 15 is set to a size that can prevent the adhesive 6 from passing through the recess 15 due to its own weight. Therefore, the adhesive 6 filled in the internal space of the mounting hole 1b above the holder 10 does not pass through the recess 15 downward depending on its own weight. However, the concave portion 15 does not need to completely prevent the adhesive 6 from passing through the concave portion 15, and may allow the adhesive 6 to pass through the concave portion 15 as long as it is a slight amount. As will be described later, after the mounting hole 1b is filled with the adhesive 6, the nozzle 5 is extracted from the mounting hole 1b, and then the anchor bolt 2 is inserted into the mounting hole 1b. If the adhesive 6 does not fall through the recess 15 and fall from the lower end opening of the mounting hole 1b after the nozzle 5 is pulled out and before the anchor bolt 2 is inserted, a slight amount of the adhesive 6 is used. The size of the recess 15 may be determined so that can pass through the recess 15.

  In this embodiment, since the adjacent side surfaces of the two protrusions 13 and 13 adjacent to each other in the circumferential direction of the main body 11 intersect each other, the recess 15 is defined by the two protrusions 13 and 13. Has been. However, such a configuration is not necessarily required, and the protrusions 13 and 13 may be arranged apart from each other in the circumferential direction of the main body 11. In that case, the recess 15 is defined by two projecting portions 13 and 13 adjacent to each other in the circumferential direction of the main body portion 11 and the outer peripheral surface of the main body portion 11 located between them.

  As shown in FIG. 3, the nozzle 5 to which the holder 10 is attached is inserted into the mounting hole 1b from its lower end opening. The nozzle 5 is inserted to a position where the upper end surface is separated from the bottom surface of the mounting hole 1b by a predetermined distance. That is, when discharging the adhesive 6 from the tip opening of the nozzle 5, the nozzle 5 moves into the attachment hole 1 b so that the tip surface of the nozzle 5 is as close to the bottom surface as possible within the range where the bottom surface of the attachment hole 1 b does not get in the way. Inserted. Thereafter, the adhesive 6 in the cartridge 3 is pushed out from the discharge port 3a by the discharge device. The adhesive 6 pushed out from the discharge port 3 a passes through the inside of the connecting cylinder 4 and the nozzle 5 and is injected from the upper end opening of the nozzle 5 to the upper end of the mounting hole 1 b. As a result, the adhesive 6 is sequentially filled into the mounting hole 1b from the bottom side. When a predetermined amount of the adhesive 6 is injected, the adhesive 6 is filled in the entire mounting hole 1 b above the holder 10. The filled adhesive 6 tries to pass through the recess 15 downward, but the recess 15 prevents the adhesive 6 from passing through due to its own weight. When the adhesive 6 is injected, the air in the mounting hole 1 b above the holder 10 flows downward through the inside of the recess 15 and between the outer peripheral surface of the nozzle 5 and the inner peripheral surface of the injection hole 12. To do.

  When the entire mounting hole 1b above the holder 10 (excluding the space occupied by the nozzle 5) is filled with the adhesive 6, the nozzle 5 is pulled out from the injection hole 12 while maintaining the injection state from the nozzle 5. It is. In this case, the nozzle 5 is pulled out at a speed corresponding to the injection amount. Therefore, a space in which the adhesive 6 is not filled in the portion where the nozzle 5 has been inserted does not occur. When the adhesive 6 is filled in the entire mounting hole 1b above the holder 10, the injection from the nozzle 5 is stopped, and the nozzle 5 is extracted from the injection hole 12 of the holder 10 as shown in FIG. Further, it is extracted downward from the mounting hole 1b. After that, as shown in FIG. 7, the anchor bolt 2 is inserted into the mounting hole 1b with its axis line aligned with the axis line of the mounting hole 1b. When the upper end surface of the anchor bolt 2 hits the lower surface of the main body 11 of the holder 10, the holder 10 moves upward as the anchor bolt 2 moves upward. Then, the pressure applied to the adhesive 6 filled above the holder 10 increases, and the adhesive 6 passes through the recess 15 downward as the holder 10 moves upward. Therefore, the anchor bolt 2 can be inserted into the mounting hole 1b while moving the holder 10 upward by moving upward with a force of a predetermined magnitude or more. In addition, since the injection port 12 is blocked by the upper end surface of the anchor bolt 12, the adhesive 6 hardly flows downward through the injection port 12.

  As shown in FIG. 1, when the anchor bolt 2 is inserted into the mounting hole 1b up to a predetermined position, the adhesive is applied to the entire space excluding the space occupied by the anchor bolt 2 and the holder 10 in the internal space of the mounting hole 1b. 6 is filled. Of course, when the anchor bolt 2 is inserted into the mounting hole 1b to a predetermined position, the position of the holder 10 at the time of injection of the adhesive 6 is predetermined so that the entire mounting hole 1b is filled with the adhesive 6. -ing

  The anchor bolt 2 is inserted until the upper surface of the anchor bolt 2 is spaced a predetermined distance downward from the bottom surface of the mounting hole 1b, but is mounted until the upper surface of the anchor bolt 2 abuts the bottom surface of the mounting hole 1b via the holder 10. The adhesive 6 may be filled in the entire mounting hole 1b except for the space occupied by the anchor bolt 2 and the holder 10 at that time when inserted into the hole 1b.

  After the anchor bolt 2 is inserted into the mounting hole 1b to a predetermined position, the state is maintained for a predetermined time. Thereby, the adhesive 6 in the mounting hole 1b is sufficiently solidified. When the adhesive 6 is solidified, the anchor bolt 2 is fixed to the mounting hole 1b.

  Thus, when the adhesive 6 is injected into the mounting hole 1b using the holder 10 according to the present invention, the holder 10 receives the injected adhesive 6. Therefore, the adhesive 6 does not fall from the lower end opening of the mounting hole 1b. Further, when the anchor bolt 2 inserted into the mounting hole 1b hits the holding tool 10 and pushes it up, the adhesive 6 passes through the recess 15 downward. Therefore, the anchor bolt 2 can be inserted into the mounting hole 1b even after hitting the holding tool 10. Moreover, the contact portion 14 prevents the holding tool 10 from moving downward with a large force. However, when the holding tool 10 moves upward, at least a downward movement of the holding tool 10 is performed with a relatively small force. It is allowed to move with a force smaller than that required for movement. Therefore, the anchor bolt 2 can be easily inserted into the mounting hole 1b even after hitting the holder 10. When the anchor bolt 2 is inserted into the mounting hole 1b to a predetermined position, the adhesive 6 is filled in the entire mounting hole 1b. Therefore, when the adhesive 6 is solidified, the anchor bolt 2 is fixed to the mounting hole 1b.

  FIG. 9 shows a second embodiment of the holder according to the present invention. The holder 10A of this embodiment has three protrusions 13 formed. Each protrusion 13 has an angle formed by both side surfaces of 60 °. Moreover, the side surfaces adjacent to each other of the two protruding portions 13 and 13 adjacent to each other in the circumferential direction of the main body portion 11 are smoothly connected without any step. As a result, the planar view shape of the entire holder 10A is an equilateral triangle. For this reason, when the holder 10A alone is viewed, no concave portion is formed on the outer periphery thereof. However, as shown in FIG. 9A, when the holder 10A is inserted into the attachment hole 1b, the attachment hole 1b A recess 15 is formed by the side surfaces of the two projecting portions 13, 13 with respect to the inner peripheral surface. Of course, the size of the recess 15 is determined in consideration of the flow of the adhesive 6 as in the case of the recess 15 of the above embodiment.

  FIG. 10 shows a third embodiment of the present invention. The holder 10B of this embodiment is a modification of the embodiment shown in FIG. That is, in this holder 10B, four protrusions 13 are formed. As a result, the planar view shape of the holder 10B is a square shape.

  FIG. 11 shows a fourth embodiment of the present invention. The holder 10C of this embodiment is a modification of the holder 10 of the first embodiment, and has five protruding portions 13 formed therein. As a result, the planar view shape of the holder 10C is a human hand shape or a star shape.

  The holder according to the present invention can adopt another form. For example, the tip of the protrusion 13 may be bent in two stages. That is, in the first stage of bending, the tip side portion is bent so as to extend obliquely downward and outward from the bent portion, and in the second stage of bending, the tip side portion is inclined obliquely downward and inward. Bend like so. A portion between the first-stage bent portion and the second-stage bent portion is defined as a contact portion. The diameter of the circle formed by the tip edge of the portion closer to the tip than this abutting portion, that is, the portion heading obliquely inwardly from the abutting portion (hereinafter referred to as the clamping portion) is made slightly smaller than the outer diameter of the anchor bolt 2. To do. If it does in this way, the anchor bolt 2 inserted in the attachment hole 1b can be hold | maintained with a holder by clamping the outer periphery of the anchor bolt 2 by each clamping part. Therefore, it is not necessary to hold the anchor bolt 2 by manpower or other equipment until the adhesive 6 is solidified, and the labor of construction can be saved by that much.

In addition, this invention is not limited to said embodiment, A various modification is employable in the range which does not deviate from the summary.
For example, in the above embodiment, the fluid substance holders 1 to 1C according to the present invention are used to hold the adhesive 6, but may be used to hold an adhesive other than the adhesive. . Moreover, as an adhesive agent, it can be used for both an inorganic adhesive agent and an organic adhesive agent.
In the above embodiment, the recess 15 is employed as the semi-circulation portion. However, a through hole is formed between the outer peripheral surface of the main body portion 11 and the inner peripheral surface of the injection hole 12. It is good also as a semi-circulation part.
In the above embodiment, the nozzle 5 is inserted into the injection hole 12, and as a result, the adhesive 6 circulates inside the injection hole 12 through the nozzle 5. That is, the adhesive 6 is indirectly circulating through the injection hole 12. However, the adhesive discharged from the nozzle 5, the connecting cylinder 4 or the discharge port 3a by abutting the upper end surface of the nozzle 5, the upper end surface of the connecting cylinder part 4, or the upper end surface of the discharge port 3a with the lower surface of the main body part 11. The agent 6 may be directly circulated through the injection hole 12.
Further, in the above-described embodiment, the anchor bolt 2 is fixed to the mounting hole 1b. However, a deformed reinforcing bar such as a threaded reinforcing bar and other objects to be fixed may be fixed to the mounting hole 1b.

  The fixing agent holder according to the present invention causes the fixing agent to fall downward from the mounting hole when injecting and filling a fixing agent having fluidity such as an adhesive into the mounting hole with the opening facing downward. It can utilize as a member for preventing.
