Description

  The present invention relates to a novel two-component contact-type non-mixing application nozzle capable of discharging two-component adhesives in contact with each other and not mixed, and application of two-component adhesives using the same The present invention relates to a method and an anchor bolt fixing method.

  Conventionally, for mixed application of two-component (two-component) adhesives, each component of the adhesive is distributed and stored in a double cartridge or tube, and a double cartridge gun and a tube extrusion device are used during use. A method of extruding and discharging two components is known (see Patent Documents 1 and 2). Further, there are also known devices in which the cartridge is made into a double tube, or the room is separated before and after the cartridge so that it can be pushed out with a normal cartridge gun as if it were one cartridge. Furthermore, a machine specialized for mixed application of two-component adhesives and fillers, such as Copper IV (trade name of a two-component mixing applicator manufactured by Naka Liquid Control Co., Ltd.), is also commercially available.

  In these methods, when mixing the two-component adhesive, a component (static mixer element, static mixer, or mixing element) for mixing the two-component adhesive at the tip of the cartridge or the tip of the two-component discharge port is used. A method is adopted in which a two-component adhesive is mixed by attaching a two-component adhesive to the nozzle (see Patent Document 3). As shown in FIG. 15, the conventional static mixer element built-in type nozzle 200 has a discharge passage 220 penetrating in the longitudinal direction, a tip portion being a tapered portion 214, a nozzle body 212 having a discharge port 216, A flange 218 provided at the rear end of the nozzle body 212, a blade-shaped reinforcing member 224 provided at the peripheral edge of the nozzle body 212, a static mixer element 223 provided in the nozzle body 212, It is comprised so that it may contain.

In this method, since the two-component adhesive is mixed in the nozzle and discharged in a mixed state (mixed state), if an adhesive that cures quickly is used, it will be cured quickly and from the nozzle. The adhesive will not come out. That is, the usage time of the adhesive is restricted with respect to the application of the adhesive.

  Furthermore, since the static mixer element is installed in the nozzle, the passage resistance (pipe resistance, pressure loss) of the adhesive that passes through the nozzle is generated. There was a problem. For this reason, when using a two-component mixing coating machine, there was a fault that a high viscosity adhesive cannot be used. Especially when a long nozzle, which is necessary for inserting long anchor bolts, is used, or when it is used in the low temperature season in winter, the adhesive becomes highly viscous at low temperatures due to the temperature dependence of the adhesive viscosity. Discharging became very difficult. When trying to forcibly discharge, side leakage from the nozzle mounting portion and leakage from the piston portion of the cartridge occurred, and the cartridge gun was soiled. When trying to push it forcibly, an accident such as damage to the cartridge occurred.

  Conventionally, as a method for fixing an anchor member such as an anchor bolt or an anchor pin, an object in which the tip portion of the anchor member expands and is physically fixed by hitting the head of the anchor member is generally used. However, with this method, there is a risk of loosening due to repeated stress, reduction of the tightening force due to expansion and contraction due to temperature changes during the day and night, and dropout.

  Then, not only physical fixation but the method of fixing an anchor bolt chemically using an adhesive together is also proposed (patent document 4). It has been reported that this method of chemically fixing anchor bolts enables more highly reliable fixing than when only physical fixing is used. In addition, as a method of applying an adhesive when used in combination with an adhesive, a glass tube, a plastic tube, or a container made of a plastic film is not mixed with a curable resin such as vinyl ester resin and an organic peroxide such as benzoyl peroxide. Thus, an adhesive-encapsulated capsule stored separately is proposed (Patent Document 5). These adhesive-encapsulated capsules are called so-called chemical anchors.

  In this anchor bolt fixing method, the adhesive encapsulating capsule is inserted into a perforation of a base material such as concrete, then the anchor bolt is inserted, and the partition wall of the adhesive encapsulating capsule is broken by the anchor bolt in the perforation. A method is adopted in which an anchor bolt is fixed by mixing and curing an organic peroxide. In order to facilitate mixing, an anchor bolt is attached to the tip of a rechargeable screwdriver drill or the like and mixed by applying rotation or vibration. However, in the case of chemical anchors, it has been troublesome to prepare adhesive-encapsulated capsules of various sizes and lengths according to various sizes of perforations with different inner diameters and depths. In the case of chemical anchors, the adhesive encapsulated in the capsule has a low viscosity and low SVI viscosity characteristics. In order to prevent this, it was necessary to prepare a sealant separately.

  In addition, when fixing the anchor bolt using the method of applying the two-component adhesive by mixing the two components in the nozzle and mounting the nozzle incorporating the static mixer element for mixing the two components described above, There is a method in which a nozzle with a built-in static mixer element for two-component mixing is installed, two components are mixed in the nozzle, discharged into the two-component adhesive punch, and then fixed by inserting anchor bolts. It was.

  In this method, a mixture of two liquids is applied into the perforations, and no mixing operation such as rotation is required when the bolt is inserted. However, since the adhesive applied in the perforations progresses over time, when using a fast-curing adhesive, it is necessary to insert a bolt immediately after the adhesive is applied. In particular, a series of operations had to be performed quickly because the adhesive hardened quickly at high temperatures in summer. Furthermore, due to problems such as nozzle clogging due to hardening of the adhesive in the static mixer element for two-component mixing, there is a problem that it is necessary to frequently replace the nozzle. For example, a slow-curing adhesive can be prepared as a countermeasure for the summer, but it has been cumbersome in terms of management, such as changing the adhesive depending on the season.

  Next, as a nozzle for applying a two-component adhesive in an unmixed state, a nozzle in which the flow path of the nozzle is separated by a partition so that the two-component adhesive is not mixed in the nozzle is applied for in this application. It has been proposed by humans (Patent Document 6).

  As shown in FIG. 16, the conventional nozzle 100 with a built-in partition wall has a discharge passage 120 penetrating in the longitudinal direction, a tip 114 is a step 114, a nozzle main body 112 having a discharge outlet 116, and the nozzle main body. 112 is configured to include a flange 118 provided at the rear end of 112 and a partition wall 123 that divides the discharge passage 120 in the longitudinal direction.

In this method, since the two components of the two-component adhesive are completely separated in the nozzle by the partition provided in the nozzle, the adhesive can be applied without considering the usable time of the adhesive. However, it is necessary to prepare many kinds of nozzle thicknesses and lengths in order to apply in drills of various depths and diameters, and the cost of molds for nozzle production is enormous. There is a disadvantage that it becomes, and it is disadvantageous in terms of cost to prepare a variety of products for application in the drilling such as anchor bolt fixing.
Japanese Utility Model Publication No. 2-138183 Japanese Utility Model Publication No. 5-80563 JP 62-298473 A Japanese Patent Application Laid-Open No. 61-2779 JP 61-254681 A Japanese Patent Laid-Open No. 09-077099 JP 2002-241706 A

  The present invention has been made in view of the above problems, and (1) a simple structure is not costly, (2) a two-component adhesive can be easily applied, and (3) a two-component Novel two-component non-mixing application nozzle capable of discharging mold adhesives in contact with each other and not mixed, adhesive application method using the same, and anchor bolt fixing using the same It aims to provide a method.

  The two-component contact-type non-mixing application nozzle according to the present invention includes a first adhesive container filled with agent A and having a first discharge opening, and a second adhesive filled with agent B and having a second discharge opening. A two-component non-mixing application nozzle attached to the tip of a two-component adhesive application device for applying a two-component adhesive containing a container, wherein the agent A from the first discharge opening and the A discharge passage provided penetrating in the longitudinal direction for passing the B agent from the second discharge opening, and a discharge hole provided in communication with the discharge passage for discharging the A agent and the B agent; The structural viscosity index of the A agent and / or B agent is 1.5 or more and the viscosity is 10 to 500 Pa · s, and the A agent and the B agent are the nozzle body. Are in contact with each other and in an unmixed state. Characterized in that so as to be discharged remains unmixed state. In the present invention, the values of the viscosity and the structural viscosity index are measured under measurement conditions of 23 ° C. based on JISK6833.

  When the agent A and the agent B are brought into contact with each other and not mixed in the nozzle body as described above, the boundary between the two liquids (that is, a thin cured film) is almost at the center of the discharge passage of the nozzle body. I can do it. Therefore, the agent A and the agent B can exist in a non-mixed state for a while while being in contact with each other. In addition, the state of the contact state and the non-mixed state described in this specification includes a state in which a thin cured film is formed at substantially the center of the discharge passage of the nozzle body.

  The nozzle body may have a discharge passage penetrating in the longitudinal direction, but a long cylindrical body is preferably used. The outer diameter and length of the nozzle body may be selected in accordance with the object to be applied, for example, the diameter and depth of the perforation, etc. The nozzle body preferably has a thickness of about 80%, and the length of the nozzle body is about 1.2 to 1.5 times the depth of the perforation. If the nozzle body is too thin with respect to the inner diameter of the perforation, the resistance during ejection is large and difficult to apply, and if it is too thick, it becomes difficult to insert the nozzle body itself.

  The ratio of the outer diameter to the length of the nozzle body is preferably (length / outer diameter) of 5 to 50, more preferably about 10 to 40. If the ratio of the outer diameter to the length of the nozzle body is smaller than 5, for example, when the two-liquid contact type non-mixing application nozzle according to the present invention is used for the anchor bolt fixing method, the applicable perforation depth is It becomes shallower and the pullout strength of the anchor bolt is lowered. Conversely, if it is 50 or more, the perforation becomes unnecessarily deep, and the amount of adhesive applied increases, which is not preferable. Furthermore, when the ratio of the outer diameter to the length of the nozzle body is 50 or more, the flow resistance at the time of discharging the two-component adhesive increases, and a great amount of force is required for discharging. Becomes exhausted and disadvantageous. In addition, when the flow resistance at the time of discharge increases, the time required for discharge becomes longer, which is inefficient. In order to solve the problem of flow resistance at the time of discharge, the use of an air type gun (air gun) is conceivable, but there is a demerit that it is necessary to secure an air source such as a compressor and the freedom of action is also hindered. The two-component non-mixing application nozzle according to the present invention is a nozzle that is attached to the tip of the two-component adhesive applicator, and therefore is a cartridge type two-component adhesive that does not use an air source such as a compressor. Needless to say, the present invention can be applied to any pneumatic gun (air gun) using an air source such as a coating device or a compressor.

  As described above, the outer diameter of the nozzle body is selected according to the adhesive object, for example, the inner diameter of a drill hole into which an anchor bolt is driven, but the outer diameter of 3 mm or more has a low flow resistance during discharge. It is preferable because it can be easily applied. In addition, about the thickness of a nozzle main body, 0.5 mm-1.5 mm are preferable.

  The shape of the nozzle body is preferably a long cylindrical body, and is particularly preferably configured as a tapered long cylindrical nozzle body having a tapered portion so that the tip of the nozzle body is tapered. Moreover, you may comprise as a taper elongate cylindrical nozzle main body which provided the some step so that the front-end | tip of a nozzle main body may become tapered.

  The cross-section of the nozzle body has a cross-sectional shape in which a two-liquid boundary can be formed at substantially the center of the discharge passage of the nozzle body when the two components of the two-component adhesive are discharged from the nozzle body at a ratio of 1: 1. For example, a circle, an ellipse, and a polygon are preferable. If the cross section of the nozzle body is oval (widely flat), etc., the two liquids will contact at the center of the ellipse's short direction (minor axis direction), and a cured thin film will be formed in the short direction of the ellipse. Is preferred. That is, in the case where the cross section of the nozzle body has a shape having a major axis and a minor axis such as an ellipse, the two-component component is so formed that a cured thin film formed by contact of the two-component components is formed in the minor axis direction. The contact state and the non-mixing state are preferable.

  In this way, if the boundary between the two liquids (that is, a thin cured film) is formed almost at the center of the discharge passage of the nozzle body, the flow path of the two liquids is secured, so the nozzle body is clogged by curing. There will be no restriction on the usable time of the adhesive. Therefore, even if the operation is interrupted for a long time, the nozzle body is not clogged, and the operation can be resumed immediately.

  No special operation is required to resume the work. In the two-component contact type non-mixing application nozzle according to the present invention, the discharge port and the inside of the nozzle body are not clogged with the cured adhesive, and the nozzle body contains each adhesive of the two-component adhesive application device. It can be used until the adhesive in the adhesive container (eg, cartridge) runs out. Since the cured coating by the two-component curing reaction acts as a partition wall, even when a fast-curing two-component adhesive that cures in minutes is used, it can be discharged even after 2-3 days from the interruption of operation.

  In addition, when applying the two-component adhesive using the two-component contact type non-mixing application nozzle according to the present invention, it is preferable that the two-component flow path in the nozzle body can be visually observed. It is desirable that the nozzle body is made of a transparent or light milky white so that it can be easily confirmed that it flows without being mixed. In particular, when applied in a perforation of a base material such as concrete, a transparent material is superior in that the flow state of the two liquids can be confirmed before entering the perforation. Although nozzles made of metal or opaque plastic can be used, there is a disadvantage in that the non-mixed state cannot be confirmed unless the two-pack type adhesive is discharged.

  As the material of the nozzle body, a thermoplastic nozzle such as polyethylene, polypropylene, nylon, or a metal nozzle made of aluminum, stainless steel, or the like can be used. From the viewpoint of ease of moldability, blow molding and injection molded products made of thermoplastics are preferred.

  When attaching the two-component contact type non-mixing application nozzle according to the present invention to the tip of the two-component adhesive application device, it can be installed by any method such as screw-in type, cap nut type, fitting type, hose band type, etc. However, the fitting type is excellent in terms of ease of attachment.

  Examples of the two-part adhesive application device include the conventional double cartridge and gun described above, a double can cartridge and a gun, a front and rear two-part cartridge and a normal cartridge gun, and a two-part dispensing device. Those already on the market can be used. As the discharge ratio of the two liquids from the adhesive container, for example, the cartridge, containing the adhesives of these two-pack type adhesive applicators, the discharge ratio ratio of Agent A: Agent B or Agent B: Agent A is 10: 1. Those of ˜1: 1 can be suitably used in the present invention. When discharging with the two-component contact-type non-mixing application nozzle according to the present invention, a cured thin film is generated, and the agent A: agent B or agent B: agent A is discharged in that it is easy to secure a flow path in the non-mixing part. The ratio is more preferably 3: 1 to 1: 1, and still more preferably 1: 1. If the mixture ratio of the two liquids is larger than the ratio of the discharge ratio of A agent: B agent or B agent: A agent is greater than 3: 1, it becomes difficult to secure the flow path for the component with less amount, and the discharge port is blocked. There is a concern that it will end up.

  The nozzle body is not provided with a partition wall that separates two liquids as in the prior art, and an adhesive container containing each adhesive of a two-part adhesive application device, for example, two liquids discharged from a cartridge. The adhesives are in contact with each other in the nozzle body and become unmixed. Then, the two-part adhesive is pushed out from the discharge port of the nozzle body in this non-contact state, and the adhesive discharged in this way starts a curing reaction at the contact surface of the two-part components, resulting in a thin cured coating. Is generated. Thus, even if a partition wall is not provided as in the prior art, the two components are separated by the generated cured film, and the cured film serves as a partition wall. Since the cured thin film is bonded and fixed to the side wall of the nozzle, it is not extruded from the nozzle body together with the adhesive.

  Examples of the two-component adhesive used in the two-component contact-type non-mixing application nozzle according to the present invention include acrylic adhesives, epoxy adhesives, urethane adhesives, unsaturated polyester adhesives, and vinyl ester adhesives. A two-component reaction curable adhesive such as an adhesive can be used. Among these, acrylic, unsaturated polyester, and vinyl ester are preferable because the main composition of the two components is close. Since these adhesives are close to each other in the main component of the two liquids, there is little effect that the two components dissolve or mix with each other, and mutual erosion due to compositional differences at the contact surfaces (the mating surfaces) is unlikely to occur. There is an advantage that the cured film on the surface becomes thin and the non-mixed portion increases. In addition, these adhesives have an advantage that they are fast-curing, rapidly react and cure at the contact surfaces of the two liquids, and a thin cured film, that is, a cured thin film is quickly formed.

  In the two-component contact type non-mixing application nozzle according to the present invention, the partition wall for isolating the two components as described in Patent Document 6 is not provided inside the nozzle body. Therefore, for example, an adhesive container containing each adhesive of a two-component adhesive applicator, for example, a two-component adhesive extruded from a cartridge, is brought into contact with each other in the nozzle body and in an unmixed state at the discharge port. It is pushed out towards. The two-component adhesive discharged from the discharge port in this way starts a curing reaction at the contact surface with each other, and a cured coating is generated. The two components are separated by the generated cured film to be in an unmixed state, and the cured thin film plays the role of the partition even if the partition is not provided as in the prior art. Since the hardened film is adhered and fixed to the inner side wall of the nozzle body, it is not extruded together with the two-component adhesive.

  The two-component contact-type non-mixing application nozzle according to the present invention has less flow resistance at the time of ejection as compared with a nozzle having a built-in static mixer element, and therefore requires less force at the time of application. Therefore, a relatively long nozzle can be used, and there is an advantage that the adhesive can be easily applied in the deep perforations, which has been difficult to apply conventionally.

  In the two-component contact-type non-mixing application nozzle according to the present invention, the flow characteristic of the adhesive is also a large factor. Two-component adhesives that are mixed immediately when the two components overlap, or when the viscosity difference between the two components is large, and the structural viscosity value of the adhesive (Structural Viscosity Index: SVI) If the pressure is low, mixing of the two liquids is likely to occur during extrusion, and a thick cured film is generated in the nozzle body due to the reaction of the two liquids, causing the nozzle body to become clogged, and the cured film to meander or twist. The flow of the unreacted part is not secured with sufficient width, and it is difficult to discharge in a good non-mixed state of contact, the resistance at the time of discharge is large, and the work becomes difficult .

  A ratio of the viscosity of the two-component adhesive composed of the A agent and the B agent (viscosity of the A solution / viscosity of the B solution) of 0.5 to 3 is preferable because mixing of the two components hardly occurs, and 0.8 to 1. The case of 2 is more preferable. In the two-component contact-type non-mixing application nozzle according to the present invention, there is a concern that when there is a difference in the viscosity of the two components, the action of mixing with each other works and the non-mixed state cannot be maintained. When the viscosity of the two components is 10 Pa · s or more and the structural viscosity index (hereinafter referred to as SVI) is greater than 1.5, the two-component adhesive is in contact with the two liquids without being familiar with each other. As it is, it is pushed out and flows in the flow direction of the nozzle. The SVI value of the agent A and / or the agent B needs to be 1.5 or more, preferably 1.5 to 10, more preferably 2 to 7 gives a good result. If the SVI value of agent A and / or agent B is less than 1.5, the two liquids will easily flow and mix after application, and the unmixed state cannot be maintained. Note that the SVI value of agent A and / or agent B is 1.5 or more means that the SVI value of either agent A or agent B may be 1.5 or more, both agent A and agent B. This means that the SVI value may be 1.5 or more. An adhesive having such a flow characteristic has an advantage that a problem of flowing out, which becomes a problem when a hole is perforated on the wall of the tunnel ceiling surface and the adhesive is applied in the perforation, does not occur.

  The viscosity of the A agent and / or the B agent of the two-component adhesive composed of the A agent and the B agent needs to be 10 to 500 Pa · s, more preferably 50 to 200 Pa · s. . When the viscosity is 10 Pa · s or less, the adhesive easily flows, and it is difficult to apply and maintain the shape after application in a non-mixed state. When the viscosity is 500 Pa · s or more, the flow resistance at the time of discharge is large, and at low temperatures in winter Discharge becomes difficult. In this case, if the adhesive is heated with a hot water bath or the like, the discharge becomes easy, but there is no change in the troublesomeness. Furthermore, when the non-mixing nozzle of the present invention is used, the viscosity of the two-component adhesive exceeds 300 Pa · s, which has a large flow resistance and cannot be discharged with a nozzle with a built-in static mixer that has been conventionally used. It was possible to discharge easily even with various viscosities. This has the advantage that the viscosity of the adhesive increases in the winter and the work is easy to perform when it is applied in thin and long perforations.

  Patent Document 7 describes a clay-like two-component radical-reactive composition containing bentonite-based minerals and mica powder. With this composition, a thin cured film can be formed as much as possible on the two-component contact surface. And since it cannot be partially cured, it is described that the two liquids can be kept in contact with each other. Further, it is described that when no clay mineral is contained, a curing reaction occurs immediately when the two liquids come into contact with each other, resulting in a partially cured product. In the present invention, even if it does not contain clay minerals such as bentonite and mica, as long as the viscosity and the structural viscosity index are within the above-described range of the present invention, a thin cured product is formed only on the contact surface of the two liquids. , Does not produce a partially cured product. In clay, it is very difficult to apply using a nozzle, but even if it can be applied in the perforation, it is difficult to mix the two liquids by rotating the anchor bolt. The adhesive used in the two-component contact type non-mixing application nozzle according to the present invention has an appropriate fluidity so that it can be easily applied in the perforation, the anchor bolt can be easily inserted, and the mixing operation by rotation etc. is also smooth. It can be done.

  A two-component adhesive coating method according to the present invention is a two-component adhesive coating method for applying a two-component adhesive composed of an agent A and a component B, and the two-component contact-type non-mixed coating. The agent A and the agent B are applied in contact with each other and in an unmixed state using a nozzle.

  It was confirmed that even when the adhesive was applied in this way, only a thin cured film was formed on the contact surface of the two liquids, and the applied two-part adhesive did not cure completely. Has been.

  A first aspect of the anchor member fixing method according to the present invention is an anchor member fixing method for inserting and fixing the anchor member in a base material in which a hole for inserting the anchor member is opened. A two-part adhesive non-mixing injection step of discharging and injecting the two-part adhesive into the perforation in contact with each other and in an unmixed state using the two-part contact non-mixing application nozzle; and an anchor member in the perforation A two-part adhesive mixing step of mixing the two-part adhesive injected into the perforation and inserted into the perforation by curing the mixed two-part adhesive An anchor member fixing step in which the anchor member is fixed in the perforation. The anchor member is inserted while rotating or vibrating as necessary.

  Even if a thin cured film is formed on the contact surface of the two-component adhesive when applied in the perforation, the cured thin film is dispersed when the anchor bolt is inserted in the next step, and the anchor bolt It is not a hindrance to adhesive fixation. In addition, when inserting an anchor bolt into a drilling hole, it is preferable to insert it while rotating or vibrating. Even if a cured thin film is produced in this way, for example, the above-mentioned chemical anchor uses glass containers, plastic containers, and film containers that are thicker than the cured thin film. Obviously, the cured film is not a problem at all, since it does not matter if the container is crushed and mixed with the two-part adhesive.

  Since the cured thin films produced on the contact surfaces of the two-component adhesive applied by the two-component contact-type non-mixing application nozzle according to the present invention are cured products of the adhesive, they are discharged in contact with each other and in an unmixed state. In addition, it is the same as that obtained by mixing and curing the two-component adhesive, and there is no risk of becoming a void and reducing the strength of the cured product. Further, it also serves as a spacer that is dispersed in the perforations and prevents the anchor bolts from being evenly aligned. For this reason, conventionally, glass beads or the like were used as spacers in order to insert the bolts in the perforations without being uniaxial, which caused voids in the adhesive layer after curing. There is no need to mix anything that causes voids.

  A second aspect of the anchor member fixing method according to the present invention is an anchor member fixing method for inserting and fixing the anchor member in a base material in which a hole for inserting the anchor member is opened. The anchor member with an adhesive injection port is inserted into the perforation, and the curable resin of the anchor member with the adhesive injection port using the two-liquid contact type non-mixing application nozzle A two-component adhesive non-mixing injection step for discharging and injecting the two-component adhesive into the perforation from the injection port in contact with each other and in an unmixed state, and the two components from the adhesive outlet of the anchor member with the adhesive injection port A mixing and discharging step of discharging while the mold adhesive is mixed, and anchor member fixing in which the anchor member inserted into the perforation is fixed in the perforation by curing the mixed and discharged two-part adhesive Characterized in that it comprises a degree, the. The anchor member is inserted while rotating or vibrating as necessary.

  As the anchor member with an adhesive injection port, an anchor member having an adhesive flow path penetrating in the longitudinal direction and having an adhesive injection port provided at the rear end is preferably provided. For example, super anchor pin PNA-70 (Cemedine Co., Ltd.) is used. This anchor member with an adhesive injection port has been developed particularly for injection reinforcement of an adhesive to a junker portion (gap portion) of a base material such as concrete.

  When this anchor member with an adhesive injection port is used and the two-component adhesive is discharged and injected into the perforation from the adhesive injection port of the anchor member with the adhesive injection port in a contact state and a non-mixed state, the adhesive The two-part adhesive leaks from the adhesive outlet of the anchor member with the inlet while being mixed. That is, when the two-part adhesive is discharged and injected from the adhesive inlet of the anchor member with the adhesive inlet in a contact and non-mixed state, the two-part adhesive injected in the contact and non-mixed state is obtained. It is discharged from the adhesive outlet through the adhesive flow path of the anchor member with adhesive injection port.

  Moreover, if the 2nd aspect of the fixing method of the anchor member which concerns on this invention mentioned above is used, there exists an advantage that reinforcement with the adhesive agent of the jumper part of base materials, such as concrete which was difficult conventionally, becomes possible.

  As an anchor member used in the anchor member fixing method according to the present invention, any of an anchor bolt, an anchor pin, a lock bolt, or a deformed steel bar can be used.

  The application method of the two-component contact-type non-mixing application nozzle and the two-component adhesive according to the present invention is not limited to the anchor member fixing method described above, but can be effectively used for new installations and repair applications in the civil engineering and construction fields. is there. In addition, the two-component non-mixing application nozzle and the two-component adhesive application method according to the present invention include a conventional two-component adhesive that is discharged and applied in an unmixed state on the object to be bonded. These two-component adhesives are used in combination, such as bonding of the magnetic field part of the speaker (adhesion of ferrite magnet and metal plate), mounting of the reinforcing plate of the elevator panel, and mounting of the reinforcing plate of the storage panel, etc. It can also be used effectively in the electric and electric fields, and can also be used effectively when the golf club shaft and head neck (neck) are bonded.

  According to the present invention, (1) a simple structure is inexpensive, (2) a two-part adhesive can be easily applied, and (3) the two-part adhesive is in contact with each other and mixed. A novel two-component contact-type non-mixing application nozzle capable of discharging in an untreated state, an adhesive application method using the same, and an anchor bolt fixing method using the same Has a great effect.

  Further, according to the present invention, even when applying a fast-curing type two-component adhesive, the work can be performed without being limited by the pot life. Even after applying the two-component adhesive, the work can be done without any restrictions on the pot life. It is also possible to use a two-component adhesive of fast curing type per second. Furthermore, when applying in a deep perforation, even if a long nozzle is used, the pipe resistance, that is, the flow resistance in the nozzle is small, and the application can be performed easily. Thus, since piping resistance is small, it becomes possible to use an adhesive with high viscosity.

In the two-liquid contact type non-mixing application nozzle 10A, the discharge passage 12 and the discharge port 16 are circular.

  In FIG. 4, the two-component contact-type non-mixing application nozzle 10 </ b> A is detachably attached to the distal end portion of the two-component adhesive application device 22. The two-component adhesive applicator 22 has a conventionally known structure as described in Patent Document 6, for example, and as shown in FIGS. 4 to 6, a first adhesive container containing each adhesive. And a pair of first cartridge 24 and second cartridge, which are arranged side by side as a second adhesive container and are filled separately with agent A (reference C1) and agent B (reference C2) of a two-component adhesive 26, the first discharge opening 28a and the second discharge opening 28b formed at the distal ends of the first cartridge 24 and the second cartridge 26, respectively, and the base ends of the first cartridge 24 and the second cartridge 26 A pressing lid (not shown) movably attached to the base 30, a base 30, a pushing member 32, and a fixed handle 34 and a movable handle 36 attached to the base 30, the movable handle 36 in hand By pulling on the side, the extrusion member 32 is configured to advance forward. The first discharge opening portion 28a and the second discharge opening portion 28b are configured to communicate with the discharge passage 12 so that the first discharge opening portion 28a and the second discharge opening portion 28b are discharged to the discharge passage 12 without being mixed with each other. Reference numeral 38 denotes a fixing tool rotatably attached to the upper part of the base 30. By rotating the fixing tool 38 downward, the first adhesive container and the second adhesive container, that is, the first cartridge 24 are used. The second cartridge 26 is mounted on the base 30.

  The first cartridge 24 and the second cartridge 26 are provided with a mounted portion 40. By rotating and fitting the collar portion 20 of the two-liquid contact type non-mixing application nozzle 10A to the mounted portion 40, The base end portion of the two-component contact type non-mixing application nozzle 10 </ b> A is attached to the tip portion of the two-component adhesive application device 22.

  In this state, if the pushing member 32 is moved forward by pulling the movable handle 36 toward the front side, the distal end of the pushing member 32 causes the pressing lids in the first cartridge 24 and the second cartridge 26 to move. The two parts adhesive A agent C1 and B agent C2 filled in the first cartridge 24 and the second cartridge 26 are pushed and moved forward, and the first cartridge 24 and the second cartridge 26 The ink is discharged from the one discharge opening 28a and the second discharge opening 28b (see FIGS. 4 and 5).

  The two-component adhesive A agent C1 and the B agent C2 discharged from the first discharge opening portion 28a and the second discharge opening portion 28b are in contact with each other and remain in a non-mixed state. The liquid is discharged from a discharge port 16 provided in communication with the discharge passage 12 through a discharge passage 12 provided penetrating in the longitudinal direction of the coating nozzle 10A. According to the application method of the two-component adhesive according to the present invention using the two-component contact-type non-mixing application nozzle 10A configured as described above, the A agent C1 and the B agent C2 of the two-component adhesive are: The two liquid contact type non-mixing application nozzle 10A is discharged from the discharge port 16 in a contact state with each other and in an unmixed state.

  With the two-component adhesives A agent C1 and B agent C2, the curing reaction starts at the contact surface of the two-component components, and the boundary between the two components (that is, thin curing) at the center of the discharge passage 12 of the nozzle body 18. A coating L) is produced. Thus, even if a partition wall as in the prior art is not provided, the A coating C1 and the B agent C2 are separated from each other by the generated cured coating L, and the cured coating L serves as a partition. Since the cured thin film L is bonded and fixed to the side wall of the nozzle body 18, it is not pushed out from the nozzle body 18 together with the A agent C1 and the B agent C2. In addition, the state of the contact state and the non-mixed state described in this specification includes a state in which a thin cured film is formed at substantially the center of the discharge passage of the nozzle body.

  The A agent C1 and the B agent C2 discharged in this way are applied onto the adherend, but remain in contact with each other and remain in an unmixed state, so that they are cured when left as they are. It takes time. Therefore, in order to accelerate the curing after the application of the two-component adhesive, the two components may be mixed together on the adherend. The mixing means is not particularly limited, but it is simplest to mix the A agent C1 and the B agent C2 using the tip of the two-component contact type non-mixing application nozzle 10A.

  In the two-liquid contact type non-mixing application nozzle 10A described above, an example in which the nozzle body 18 is cylindrical and the cross section is circular has been shown. It can be oval or polygonal.

  In FIG. 7, the code | symbol 10B shows another embodiment of the two liquid contact type non-mixing application nozzle which concerns on this invention. The two-component contact-type non-mixing application nozzle 10B has a discharge passage 12 penetrating in the longitudinal direction, the tip is a tapered portion 14, a nozzle body 18 having a discharge port 16, and a nozzle body 18 provided at the rear end portion. It is comprised so that the collar part 20 and the blade-plate-shaped reinforcement member 21 provided in the peripheral part of the nozzle main body 18 may be included. In the two-liquid contact type non-mixing application nozzle 10B, the discharge passage 12 and the discharge port 16 are elliptical. When the cross section of the nozzle body 18 is elliptical (widely flat) or the like, the two liquids come into contact with each other at the center of the ellipse in the short direction (minor diameter direction), and the cured thin film forms in the short direction of the ellipse. It is preferable to be configured to be formed. That is, when the cross section of the nozzle body 18 has a shape having a major axis and a minor axis such as an ellipse as shown in FIG. 7, the A of the two-component adhesive ejected from the ejection openings 28a and 28b. Two liquids in the direction shown in FIG. 7 with respect to the direction of the discharge openings 28a and 28b shown in FIG. 6 so that the cured thin film formed by the contact between the agent C1 and the agent B2 is formed in the minor axis direction. The contact-type non-mixing application nozzle 10 </ b> B is preferably attached to the attached portions 40 of the first cartridge 24 and the second cartridge 26.

  In FIG. 8, the code | symbol 10C shows other embodiment of the two-component contact type non-mixing application nozzle which concerns on this invention. The two-component contact-type non-mixing application nozzle 10C has a discharge passage 12 penetrating in the longitudinal direction, the tip is a tapered portion 14, a nozzle body 18 having a discharge port 16, and a nozzle body 18 provided at the rear end portion. It is comprised so that the collar part 20 and the blade-plate-shaped reinforcement member 21 provided in the peripheral part of the nozzle main body 18 may be included. In the two-liquid contact type non-mixing application nozzle 10C, the discharge passage 12 and the discharge port 16 are polygonal (in the illustrated example, hexagonal). Cross section in which the boundary between the two liquids can be formed at substantially the center of the discharge passage 12 of the nozzle body 18 when the two components of the two-component adhesives A agent C1 and B agent C2 are discharged from the nozzle body 18 at a ratio of 1: 1. Of course, shapes other than those shown in the drawings can also be applied.

  In FIG. 9, reference numeral 10D shows another embodiment of the two-component contact-type non-mixing application nozzle according to the present invention. The two-component contact-type non-mixing application nozzle 10D has a discharge passage 12 penetrating in the longitudinal direction, the tip is a multi-stage portion 60 so as to be tapered, a nozzle body 18 having a discharge port 16, and a nozzle body 18 And a skirt-like mounting portion 66 provided at the rear end portion. The two-component contact type non-mixing application nozzle 10D has a more elongated shape than the two-component contact type non-mixing application nozzle 10A, and is suitable for applying the two-component adhesive in deep perforations. The two-component contact-type non-mixing application nozzle 10D is attached to the two-component adhesive application device via the skirt-shaped mounting portion 66, but the basic configuration is the same as the two-component contact-type non-mixing application nozzle 10A described above. .

  Next, the 1st aspect of the fixing method of the anchor member which concerns on this invention is demonstrated based on FIGS.

  First, prior to fixing the anchor member, a hole 46 for inserting an anchor member 54 (an anchor bolt in the illustrated example) into the base material 42 is opened with a drilling drill 44 (FIG. 10A). Next, the inside of the perforation 46 is cleaned with the air blowing tool 48 (blow cleaning) (FIG. 10B), and the inside of the perforation 46 is cleaned with the brush cleaning tool 52 (FIG. 10C). Reference numeral 50 denotes shavings when forming perforations, and the above-described blow cleaning and brush cleaning are repeated as necessary.

  As shown in FIG. 10 (d), the two-liquid contact type non-mixing application nozzle according to the present invention (two-liquid contact type non-mixing application nozzle 10A in the illustrated example) is provided in the perforations 46 formed in this way. The two-component adhesive composed of the A agent C1 and the B agent C2 is injected in a non-mixed state in contact with each other (two-component adhesive non-mixing injection step; S300).

  Next, as shown in FIG. 11 (e), the anchor member 54 is inserted into the perforated 46 into which the two-component adhesive composed of the A agent C 1 and the B agent C 2 is injected, and the A injected into the perforated 46. The two-component adhesive composed of the agent C1 and the agent B2 is mixed as shown in FIG. 11 (f) (two-component adhesive mixing step; S302). At this time, the anchor member 54 is preferably inserted while being rotated or vibrated because the A agent C1 and the B agent C2 are well mixed. When the mixed two-component adhesive S composed of the A agent C1 and the B agent C2 is cured, the anchor member 54 inserted into the perforation 46 is inserted into the perforation 46 as shown in FIG. (Anchor member fixing step; S304).

  Furthermore, the 2nd aspect of the fixing method of the anchor member which concerns on this invention is demonstrated based on FIGS.

  First, prior to fixing the anchor member, perforations 46 are formed in the base material 42 such as concrete in the same manner as in the above-described Fig. 10A to Fig. 10C. 58 (an anchor pin in the illustrated example) is inserted into the perforation 46 (an anchor member insertion step with an adhesive injection port; S400), and an adhesive injection is performed using the two-component non-mixing application nozzle according to the present invention. The two-part adhesive composed of the A agent C1 and the B agent C2 is discharged and injected into the perforation 46 from the adhesive injection port 59 of the anchor member with inlet 58 in a contact state and a non-mixed state (two-part adhesive non-mixed) Injection step: S402) The anchor member 58 with an adhesive injection port is provided with an adhesive outlet 62 through which the injected adhesive comes out, and is composed of the injected A agent C1 and B agent C2. Liquid adhesive is When coming out from the adhesive outlet 62 of the anchor member 58 with an adhesive injection port, they are mixed, and mixed and discharged (mixed discharge step; S404) The mixed A agent C1 and B agent When the two-component adhesive S made of C2 is cured, as shown in FIG. 13, the anchor member 58 with an adhesive injection port inserted into the hole 46 is fixed in the hole 46 (anchor member fixing). Step: S406) The second aspect of the anchor member fixing method according to the present invention is particularly shown in FIG. 13 even when the base material 42 has a gap portion called a jumper portion. In addition, the anchor member 58 with the adhesive injection port can be fixed in the perforation 46 having the jumper portion 56.

Example 1
Liquid A and liquid B of Cemedine Y-600H (trade name of two-component acrylic adhesive manufactured by Cemedine Co., Ltd., high SVI type) are separately used in a double cartridge (mixing ratio 1: 1 cartridge). Filled. This adhesive is an adhesive having the viscosity characteristics of the viscosity of the A agent of 30 Pa · s, SVI 3.9, the viscosity of the B agent of 32 Pa · s, and SVI 3.8.

  Next, the above-described two-liquid contact type non-mixing application nozzle 10A made of polypropylene having an outer diameter of 4.7 mm and a length of 150 mm (length / diameter = 32) was fitted into the end of the double cartridge.

  A 80 mm deep hole was drilled in a concrete block with a 6.5 mm thick concrete drill, and the adhesive was applied by inserting the two-liquid contact type non-mixing application nozzle 10A. The two-component adhesive of agent A and agent B is visually confirmed by the two-component contact type non-mixing application nozzle 10A and discharged onto the concrete before being applied in the perforation, so that the two components are in contact and non-mixed. It was confirmed that it was discharged in a state. The discharge can be performed with a small resistance, and the operation is easy. An anchor pin having a thickness of 6 mm and a length of 78 mm was inserted into the perforation while rotating. Usually, the head of the anchor pin is hit next, and the tip of the pin is widened and physically fixed. However, in this case, the pin is left as it is and the effect of the adhesive as a chemical is observed.

  When it was confirmed by turning the anchor pin fixing speed by hand, it could not be turned by hand after 10 minutes, and sufficient fast curability could be confirmed. Further, after curing at 23 ° C. for 7 days, the head of the anchor pin was pulled and the pull-out strength was measured with a tester, which showed 12 KN and sufficient pull-out strength.

  Applying with the two-component non-mixing application nozzle 10A and mixing the adhesive in the perforation using the rotation of the anchor pin, the mixture becomes sufficiently mixed, the curing speed is high, and the pulling strength after curing is also high. You can see that it is secured enough.

  Next, in order to investigate the state of the two-liquid contact type non-mixing application nozzle 10A, the operation was interrupted, and the discharge of the adhesive was tried again after 1 hour, 3 hours, 24 hours, and 3 days. However, the adhesive could be re-discharged after being left for any period of time.

  In order to see the usable time of the adhesive discharged in the perforation, it is determined whether it can be inserted by rotating the anchor pin after 1 hour, 3 hours, and 24 hours after the adhesive is discharged. As a result of confirmation, it was confirmed that the two-component adhesive was kept in an unmixed state in the perforation after being allowed to stand for any period of time.

(Example 2)
Agent A (main agent) and agent B (cured) of Cemedine EP48W (trade name of two-component epoxy adhesive manufactured by Cemedine Co., Ltd., high SVI type) in a double cartridge (mixing ratio 1: 2 cartridge) Agent) was filled separately. This adhesive is an adhesive having viscosity characteristics of a main agent viscosity of 72 Pa · s, SVI 5.5, a curing agent viscosity of 58 Pa · s, and SVI 4.9.

  Next, in the same manner as in Example 1, the two-liquid contact type non-mixing application nozzle 10A made of polypropylene having an outer diameter of 4.7 mm and a length of 150 mm was fitted into the end of the double cartridge. A 80 mm deep hole was made in a concrete block with a 6.5 mm thick concrete drill, and the two-component adhesive was applied by inserting the two-component contact-type non-mixing application nozzle 10A. The two-component adhesive is visually confirmed by the two-component contact type non-mixing application nozzle 10A and discharged to the concrete before being applied in the perforations, and the two components are discharged in a contact state and a non-mixed state. It was confirmed. The discharge can be performed with a small resistance, and the coating is easy. An anchor pin having a thickness of 6 mm and a length of 78 mm was attached to the tip of a rechargeable driver drill and inserted into the drilling hole while rotating. As in the case of the acrylic adhesive, it was left as it was to see the effect of the adhesive as a chemical.

  When it was confirmed by turning the anchor pin fixing speed by hand, it could not be turned by hand after 12 hours, and hardening was confirmed. Further, after curing at 23 ° C. for 7 days, the head of the anchor pin was pulled and the pull-out strength was measured with a tester, which showed 14 KN, indicating a sufficient pull-out strength.

  Epoxy adhesives can also be applied in a non-mixed state. By mixing the adhesive in the perforations using the rotation of the anchor pin, the mixed state becomes sufficient and the drawing strength after curing is also high. You can see that it is secured enough.

  Next, in order to investigate the state of the two-liquid contact type non-mixing application nozzle 10A, the operation was interrupted, and the discharge of the adhesive was tried again after 1 hour, 3 hours, 24 hours, and 3 days. However, the adhesive could be re-discharged after being left for any period of time.

  In order to see the usable time of the adhesive discharged in the perforation, it is determined whether it can be inserted by rotating the anchor pin after 1 hour, 3 hours, and 24 hours after the adhesive is discharged. As a result, it was confirmed that the two-component adhesive was kept in contact and non-mixed in the perforation after being allowed to stand for any period of time.

(Example 3)
Agent A and Agent B of Cemedine DX500H (trade name of hybrid adhesive of two-component acrylic and modified silicon manufactured by Cemedine Co., Ltd., high SVI type) in a double cartridge (mixing ratio 1: 2 cartridge is used) Were filled separately. This adhesive is an adhesive having viscosity characteristics of A agent viscosity of 230 Pa · s, SVI6.5, B agent viscosity of 210 Pa · s, and SVI6.7.

  Next, the two-liquid contact type non-mixing application nozzle 10A made of polypropylene having an outer diameter of 4.7 mm and a length of 150 mm (length / outer diameter = 32) was fitted into the end of the double cartridge. A 80 mm deep hole was made in a concrete block with a 6.5 mm thick concrete drill, and the two-component adhesive was applied by inserting the two-component contact-type non-mixing application nozzle 10A. The two-component adhesive is visually confirmed by the two-component contact type non-mixing application nozzle 10A and discharged to the concrete before being applied in the perforations, and the two components are discharged in a contact state and a non-mixed state. It was confirmed. Despite the high-viscosity adhesive, ejection can be performed with low resistance, and coating is easy. An anchor pin having a thickness of 6 mm and a length of 78 mm was attached to the tip of a rechargeable driver drill and inserted into the drilling hole while rotating. As in the case of the acrylic adhesive, it was left as it was to see the effect of the adhesive as a chemical.

  When the fixing speed of the anchor pin was confirmed by turning by hand, it could not be turned by hand after 15 minutes, and sufficient fast curability could be confirmed. Further, after curing at 23 ° C. for 7 days, the head of the anchor pin was pulled and the pull-out strength was measured with a tester, which showed 10 KN, indicating a sufficient pull-out strength.

  Applying with the two-component non-mixing application nozzle 10A, and mixing the adhesive in the perforation using the rotation of the anchor pin results in a sufficiently mixed state, fast curing speed, and drawing strength after curing. It can be seen that is well secured.

  Next, in order to investigate the state of the two-liquid contact type non-mixing application nozzle 10A, the operation was interrupted, and the discharge of the adhesive was tried again after 1 hour, 3 hours, 24 hours, and 3 days. However, the adhesive could be re-discharged after being left for any period of time.

  In order to see the usable time of the adhesive discharged in the perforation, it is determined whether it can be inserted by rotating the anchor pin after 1 hour, 3 hours, and 24 hours after the adhesive is discharged. As a result, it was confirmed that the two-component adhesive was kept in contact and non-mixed in the perforation after being allowed to stand for any period of time.

Example 4
Next, an adhesive having a viscosity characteristic of A agent with a viscosity of 30 Pa · s and SVI of 3.9, B agent with a viscosity of 3.2 Pa · s and SVI of 3.8 is used, and the outer diameter of the nozzle is 4.7 mm. The test was conducted in the same manner as in Example 1 except that the length was changed to 350 mm (length / diameter = 74). As a result of looking at the resistance at the time of discharge, the flow resistance was large and discharge was possible at the first discharge. However, since the application exceeded 10 places, the hands were exhausted and the application became difficult. Also, the coating speed was slowed down over 1 minute / one place. However, the two-component adhesive is applied in contact and non-mixed, the two-component mixing is not occurring in the nozzle, the point of re-discharge is possible, and the bolt is inserted into the hole. As far as possible, it was as good as in Example 1.

(Comparative Example 1)
The adhesive was applied into the perforations in the same manner as in the example except that a static liquid mixer element built-in nozzle was used instead of the two-component contact type non-mixing application nozzle 10A of Example 1. When an attempt was made to insert the anchor pin into the perforation after 20 minutes had passed, the adhesive was cured and could not be inserted. It was impossible to re-discharge the adhesive.

(Comparative Example 2)
Agent A and Agent B of Cemedine Y-615 (trade name of two-component type acrylic adhesive manufactured by Cemedine Co., Ltd., low SVI type) were separately filled in a double cartridge. This adhesive is an adhesive having a viscosity characteristic that the viscosity of agent A is 3 Pa · s and SVI 1.3, the viscosity of agent B is 3.2 Pa · s and SVI is 1.4. When the application state was confirmed in the same manner as in the example, the two liquids were mixed by flow at the time when 15 minutes had elapsed after discharge, and were not in the unmixed state. Even in the nozzle, the two liquids flowed and mixed irregularly, generating a large cured product and causing clogging. Even in the discharged perforations, a hardened product was generated due to flow, and after 15 minutes, the anchor pin could not be inserted.
