Description

  The present invention is a method for carrying out various works using an epoxy resin two-component adhesive in the field of civil engineering and construction, in particular, repairing or reinforcing treatment objects represented by concrete structures. The present invention relates to a curing method for an epoxy resin two-component adhesive suitable for carrying out, and a supply device for an epoxy resin two-component adhesive suitable for use in the method.

  There are various types of concrete structures such as floor boards, piers, beams, outer walls, pedestals, dams, dams, tunnels, and buildings, as is apparent from Patent Documents 1 to 3 below. It is well known that concrete structures deteriorate over time. Most of the deterioration is like cracks, cracks, crevices, cracks, and gaps. Such deterioration (decrease in strength) may cause a concrete peeling accident. When the deterioration is severe, internal rebars may corrode and lead to structural destruction. As countermeasures, concrete structures are regularly inspected, repaired and reinforced.

  For repair and reinforcement of concrete structures, adhesive injection method, U-cut seal material filling method, seal method, packer method, etc. have already been developed. The techniques of Patent Documents 1 to 3 belong to any one of these methods.

  In the case of the adhesive injection method, in many cases, both manual and mechanical, an epoxy resin two-component adhesive is pressure-injected into each cracked portion of a concrete structure to block them. The methods of Patent Documents 1 and 2 also use an epoxy resin two-pack type as an adhesive.

  The U-cut sealing material filling method forms a U-shaped groove with an electric cutter along the cracked part of a concrete structure, and pressurizes and fills the groove with an epoxy resin two-component adhesive (sealing material) with a caulking gun. After that, it is pressed with a spatula to adhere to the ground, and the surface is finished smoothly.

  In the sealing method, an epoxy resin two-component adhesive, which is a sealing material, is applied to the cracked portion with a pate vera. More specifically, the adhesive is applied to the cracked part while pressing it with a pate vera to finish the surface smoothly.

  In the case of the packer method, this type of defect is eliminated by pressurizing and filling an epoxy resin two-component adhesive into the hollowed portion of the concrete with an injection machine.

  As is apparent from the above, epoxy resin two-component adhesives are often used for repairing and reinforcing concrete structures. The reason is that the epoxy resin system satisfies various requirements such as adhesion, durability, water resistance, alkali resistance and dimensional stability.

Japanese Patent Laid-Open No. 05-065768 JP 2002-121901 A JP 2004-183334 A

Regarding the epoxy resin two-component adhesive, the following [A] to [E] are pointed out by Patent Document 3.
[A] Since it is a two-component type, extra time is consumed to mix it.
(B) Since low-pressure injection is mainstream, mechanization and automation tend to be delayed. This makes rational work difficult and lengthens the construction time.
(C) The viscosity of the adhesive varies greatly with temperature. This means that it is greatly affected by the outside temperature in summer and winter. If the proper viscosity of the adhesive cannot be maintained, stable work cannot be performed and the finish is also deteriorated.
(D) Since the material inspection is an empty bag inspection, an accurate check cannot be performed.
[E] It takes considerable time to clean the equipment and tools required for the work.

  With regard to the above, the construction method of Patent Document 1 is difficult to cope with the problems [A] to [E] because weight is put on the reliable mixing of the two epoxy-based liquids. Although the construction method of Patent Document 2 is also good for repairing fine cracks in concrete, new improvements are required to solve the problems [A] to [E].

On the other hand, the construction method of Patent Document 3 is described as having the following features [F] to [R].
[F] Since the conveyance and mixing of the adhesive are synchronized and unified, the number of work types is reduced. This leads to streamlining of work.
[G] The main agent and the curing agent can be weighed in each supply system, and the mixing ratio of both can be substantially suppressed to zero error. As a result, the adhesive properties can be matched to the construction conditions, so that construction results as designed for repair and reinforcement can be obtained.
[H] The temperature, viscosity, pressure and the like of the main agent, the curing agent, and the mixture (uncured adhesive) can be controlled in each system. When these operations can be performed, it is possible to secure work stability by suppressing external influences (eg, the influence of outside air temperature) even in outdoor construction. This also increases the quality of repairs and reinforcements.
[I] It is only necessary to replace the tip of the mixed supply system such as a nozzle, regardless of whether the construction is application, lamination, injection, or filling. This alone can be used without difficulty even at sites where multiple types of construction are mixed.
[J] Since the main agent and the curing agent can be controlled by each system of the adhesive supply means, mechanization and automation are established. From another point of view, the dependence on workers is greatly reduced, and a high degree of finishing can be expected by mechanical work. Therefore, when combined with the above points, the work efficiency can be improved and the labor can be saved while maintaining the height of the grade, and the construction cost can be reduced.
[K] When the supply of the main agent and the curing agent is stopped, the mixture of the two remaining in the mixed supply system is cured, which closes the mixed supply system. If this is left unattended, it will be difficult to implement and use the equipment. However, the adhesive supply means includes a cleaning means for a mixed supply system. According to this, the inside of the mixed supply system can be cleaned without the mixture remaining. Therefore, the cleaning means is useful when the work is interrupted or finished. Moreover, the cleaning means guarantees freedom of work interruption.
[R] Since the main preparation is only to set the main agent and the curing agent at the site, and the main cleanup is simply to clean the mixed supply system by the cleaning means, both can be easily performed.

However, it is desired that the construction method of Patent Document 3 can also cope with the following problems [M] to [P].
[M] The mixing of the main agent and the curing agent requires considerable accuracy. If the volume mixing ratio at this time exceeds an allowable error, a predetermined reaction does not occur, and the two-component adhesive does not cure. Therefore, the mixing means requires high mixing accuracy and becomes expensive.
[N] A mixer such as a static mixer is connected with a supply pipe for a main agent and a supply pipe for a hardening agent, and the main agent and the hardening agent flow in at a volume ratio of 2: 1. In this case, Therefore, it is necessary to prevent the main agent from invading into the supply pipe for the curing agent or causing an inflow state that inhibits the ratio of the two agents. In the present situation where this is adjusted by trial and error to obtain an appropriate state, much labor and time are spent for that purpose.
[O] Even if an appropriate adjustment state of the mixer is obtained, it may fluctuate due to unforeseen circumstances. Therefore, it is necessary to deploy a mixer supervisor in addition to the repair worker.
[P] The adhesive remaining inside the mixer is cured. For this reason, the mixer should be disassembled and cleaned after the work is completed. On the other hand, although the required cleaning can be easily performed by attaching the cleaning means to the mixer, the equipment cost is increased by the amount required for the cleaning means.

  In view of such technical problems, the present invention satisfies these requirements such as simple and accurate blending and uniform mixing of the main agent and the curing agent, stable operating state of the mechanical device, reduction of initial cost and running cost. An epoxy resin two-component adhesive curing method and an epoxy resin two-component adhesive supply device are provided.

The present invention is characterized by the problem solving means shown in the following (01) to (06), and the intended object is achieved by these means.
(01) The epoxy resin two-component adhesive curing method of the present invention is an epoxy resin two-component adhesive composed of a liquid main agent and a liquid curing agent in an uncured state in the processing space of the object to be processed. In the construction method for supplying and curing this, the mixing condition is that the volume mixing ratio of the main agent: curing agent in the two-component adhesive is 2: 1, and the main agent and the curing agent are supplied. Preparing a three-system supply system for mixing and a liquid injector supplied from each of the supply systems and supplying it to the processing space of the object to be processed; Mix from these supply systems so that the main agent supply amount by one supply system, the main agent supply amount by the other one supply system, and the curing agent supply amount by the remaining one supply system become a supply ratio of 1: 1: 1. The main component and curing agent are pressurized and supplied to the injection machine to satisfy the above mixing conditions. Mixing and preparing the uncured two-part adhesive and mixing and preparing the uncured two-part adhesive that has been mixed so as to satisfy the above-mentioned mixing conditions in the mixing injector from the tip of the mixing injector It is characterized in that it is supplied into the processing space of the processing object and cured.
(02) The curing method of the epoxy resin two-component adhesive of the present invention is characterized in that, in the above (01), an allowable error in the volume mixing ratio of the main agent: the curing agent is less than ± 10%.
(03) The curing method of the epoxy resin two-component adhesive of the present invention is the treatment of the uncured two-component adhesive prepared by mixing from the tip of the mixing injector in (01) or (02) above. It is characterized by supplying pressure into the processing space of the object.
(04) The epoxy resin two-component adhesive curing apparatus of the present invention is for supplying an epoxy resin two-component adhesive composed of a main agent and a curing agent to a processing space of an object to be processed in an uncured state. In the apparatus, it is provided with three types of pressure supply systems for supplying the main agent and curing agent, and is provided with a mixing injector having a nozzle at the tip for mixing two agents, and each supply system The tip of the supply pipe is connected to a mixing injector, and each supply system and the mixing injector communicate with each other.
(05) The epoxy resin two-component adhesive curing device of the present invention is the above-described (04), in which the tip of the supply pipe in each supply system is held at a position where the supply pipes do not face each other. It is connected.
(06) The epoxy resin two-component adhesive curing device of the present invention is the above-mentioned (04) or (05), wherein the mixing unit of the mixing injector is composed of either a static mixer or a dynamic mixer. It is characterized by.

The epoxy resin two-component adhesive curing method of the present invention and the epoxy resin two-component adhesive curing device of the present invention have the following effects <101> to <108>.
<101> In the case of the construction method of the present invention, the volume mixing ratio of the main agent: curing agent in the two-pack adhesive is 2: 1 which is easy to measure and blend, so that both agents can be blended accurately and easily. As for the main agent / curing agent, the same amount of each agent is supplied in three supply systems so that the supply ratio of main agent: main agent: curing agent is 1: 1: 1, so that a predetermined amount of each agent is maintained. Thus, each agent can be supplied accurately and easily. Therefore, accurate blending of the main agent and the curing agent is easily realized without difficulty.
<102> When supplying equal amounts (pressurized supply) of each agent in three supply systems so as to have the above supply ratio (main agent: main agent: curing agent = 1: 1: 1), the volume of the main agent: curing agent Even if the mixing ratio is 2: 1, the inflow pressure of each agent in the mixing injector is balanced. When the inflow pressures are balanced in this way, it is difficult to cause a problem (hardening of the hardener inflow) that the agent having a low inflow pressure is pushed back to the supplier side by the agent having a high inflow pressure. Accordingly, the main agent and the curing agent are mixed and prepared with a predetermined blending ratio in combination with the stable supply, and the mixture becomes an adhesive and is supplied into the processing space of the processing object. Of course, an adhesive made of such a mixture has a high effective usage rate as an adhesive because the blending ratio of the main agent and the curing agent is within an allowable error range and does not cause a curing reaction failure. become.
<103> In the method of the present invention, the main agent and the curing agent merge from the mixing injector, and the two agents do not contact each other until then. Furthermore, what became an adhesive by the merging and mixing in the mixing injector is immediately supplied from the front end of the mixing injector to the processing space of the processing object. In this case, since the mixed adhesive immediately before the processing space is supplied is immediately supplied into the processing space, the supply speed of the adhesive is high in relation to the gel time. Therefore, it is difficult to make an operation mistake that the adhesive is hardened before reaching the target.
<104> About the adhesive that undergoes a curing reaction, only the mixed injection machine passes through this adhesive in the stage up to the processing space of the object to be processed. That is, the adhesive remains in the mixing and injecting machine after the supply operation, and the three supply systems and the like do not remain at all that are cured before and after the supply operation. Therefore, when the apparatus or the like is cleaned to remove the residual adhesive after the work is finished, the burden of the cleaning work is reduced.
<105> As described above, the method of the present invention has a high effective usage rate of the adhesive and is unlikely to cause an operation error. Further, the energy for supplying the main agent and curing agent, mixing both agents, and supplying the adhesive may be mainly composed of an inexpensive pressure source. The main means is also a supply system and a mixing injector. Collectively, the method of the present invention can reduce initial costs and running costs.
<106> The device according to the present invention has a simple configuration in which three pressure supply systems and a mixing injector having a nozzle at the tip thereof are connected to each other and the mixing injector communicates with each other. The present invention can be implemented in a simple and simple configuration. Therefore, the device of the present invention is useful and useful in carrying out the method of the present invention having the above effects.
<107> In the apparatus of the present invention, the tip of the supply pipe in each supply system is connected to the mixing injector while maintaining a position where the leading ends do not face each other. While each agent flows in smoothly without facing collision, each agent is vigorously stirred by inflow pressure and fluidity from different positions, so that the uniform mixing of each agent is enhanced.
<108> The apparatus of the present invention in which the mixing injector is a static mixer does not require a power source. Therefore, the running cost can be reduced accordingly. In the apparatus of the present invention, where the mixing injector is a dynamic mixer, it is possible to set the mixing output arbitrarily to realize aggressive stirring and mixing. This means that it is highly convenient because a mixed output according to the working conditions can be obtained.

  Embodiments of the epoxy resin two-component adhesive curing method according to the present invention and the epoxy resin two-component adhesive supply device according to the present invention will be described with reference to the accompanying drawings.

  1 are concrete structures (including reinforced concrete structures and cement mortar structures), earth structures (including those referred to as land and ground), ceramic structures (made of ceramics). Structure) ・ Brick structure ・ Asphalt structure ・ Gypsum structure (including gypsum mortar structure) ・ Lime structure ・ Glass structure ・ Wood structure ・ Synthetic resin structure ・ Metal It is composed of a structure made of a composite material obtained by combining any two or more of these materials. The processing object 11 includes a static structure to a dynamic structure regardless of dimensions, shapes, structures, and the like. More specifically, the object 11 to be treated is a fixed structure (eg, building), a movable installation (eg, an installation building such as a temporary hut), or a portable object (eg, a temporary building). Any structure may be used such as a separate staircase structure attached to the bleachers) or a moving body (eg, a shed with wheels pulled by a towing vehicle). A typical structure as the processing object 11 is a concrete structure. Specifically, this includes floorboards, piers, beams, outer walls, pedestals, dams, dams, tunnels, and buildings.

  The processing object 11 illustrated in FIG. 1 has a processing space 12 where processing is performed using an epoxy resin two-component adhesive described later. The processing space 12 of the processing object 11 is often different in size, shape, number, etc. for each processing object. What can definitely be said in the processing space 12 is that the adhesive can be received. To give a few specific examples of the processing space 12, they are cracks, cracks, crevices, cracks, gaps, long holes, and the like. Therefore, the processing object 11 has any one or more of these as the processing space 12. The processing space 12 such as cracks, cracks, cracks, and cracks will be described using the term “crack”. This includes surface cracks existing on the surface layer of the processing object 11 and intermediate layers from the surface layer of the processing object 11 to the intermediate layer. There are cracks and deep cracks reaching from the surface layer of the processing object 11 to the deep layer. This type of crack usually occurs or grows due to vibration or impact applied to the object 11 to be processed. On the other hand, the processing space 12 such as a gap often occurs due to the separation of the interface at the joint. The processing space 12 such as a long hole does not correspond to a crack, but the long hole becomes the processing space 12 when it becomes necessary to be closed due to use, unnecessary, or other reasons.

  The communication passage 13 illustrated in FIG. 1 is formed in the processing object 11 by a known machining means such as a drilling machine (drilling machine), a cutting machine (cutting machine), or a sawing machine (sewing machine). is there. Specifically, the communication passage 13 is formed from the surface of the processing object 11 to the inside thereof, intersects the processing space 12 of the processing object 11, and thereby communicates with the processing space 12. The communication passage 13 can be used to suck or pressurize the inside of the communication passage 13 or the inside of the processing space 12. There are cases where there is a single communication passage 13 and a plurality of communication passages 13. In any case, the communication passage 13 communicates with the processing space 12 as described above. The communication passage 13 includes a hole and a groove. As an example, the communication passage 13 is made of a hole, as another example, the communication passage 13 is made of a groove, and as another example, the communication passage 13 is made of a combination of a hole and a groove. The hole for the communication passage may have either a circular cross section or a square cross section, and usually a circular cross section is often employed. The groove for the communication passage includes a slit like a slit. The width, depth, length, and the like of the groove for the communication passage are set according to the processing space 12 of the processing object 11. The communication passage 13 including a hole and / or a groove includes at least one of a straight shape, a curved shape, a meandering shape, an inclined shape, a branched shape, a cross shape, a radial shape, a parallel shape, and a hierarchical shape. . One of the desirable examples when the communication passage 13 formed of holes as shown in FIG. 1 is used for suction is as shown in the drawing, the suction end portion of the communication passage 13 (the communication on the surface side of the processing object 11). (Passage end) is set at a position higher than each processing space 12. It is also desirable that a single communication passage 13 made of holes corresponds to two or more processing spaces 12 as shown in FIG. In the exemplary embodiment, the communication passage 13 is formed such that [communication passage 13: processing space 12] = [1: plural], but the processing space 12 and [1: 1] or [plurality: 1]. The communication passage 13 may be formed so as to correspond to the above. The communication passage 13 composed of holes is often formed to be inclined with respect to the surface of the processing object 11. The hole-type communication passage 13 formed in an inclined shape is one or more of the communication passages 13, and the entire communication passage 13 formed of holes may be formed in an inclined shape. The “inclined shape” in this case means that the angle formed between the surface of the processing object 11 and the communication passage 13 is “larger than right angle” or “smaller than right angle” in the relative relationship between the two. Accordingly, when the surface of the processing object 11 is inclined as “non-vertical surface” or “non-horizontal surface”, the communication passage 13 is formed in “vertical direction” or “horizontal direction”. Sometimes it is done. Of course, depending on the situation of the processing space 12 in the processing object 11, the communication path 13 may be formed at a right angle to the surface of the processing object 11. Therefore, when there are a plurality of communication passages 13 made of holes, the inclined communication passage 13 and the right-angle communication passage 13 may be combined. The diameter, direction, depth, and the like of the communication passage 13 are also set according to the state of the processing space 12 and the type of the adhesive 21 described later. When the communication passage 13 that penetrates the processing object 11 intentionally or due to an operation error is formed with respect to the others related to the communication passage 13, the one through end portion or the like is sealed so as to be in a non-penetration state. Close with.

  As will be described later, a mixing injector 41 and a suction system 51 are connected to the processing space 12 and the communication passage 13 on the surface of the processing object 11. In addition, a sealing material 14 is provided on the surface of the processing object 11. The sealing material 14 has adhesiveness or adhesiveness to the processing object 11 and is in close contact with the processing object 11. The sealing material 14 may be any of colorless and transparent, colored and transparent, and colored and opaque as long as it has a predetermined sealing function. Of the sealing materials 14, the type that is attached to the surface of the processing object 11 is, for example, a film or a sheet, and has an adhesive layer or an adhesive layer on the attachment surface. Of the sealing material 14, the type that is sprayed onto the surface of the processing object 11 has a thin layer attached to the surface of the processing object as a coating. The seal material 14 is provided on the entire surface of the processing object 11 as an example, or as a part of the processing object 11 (a part of the processing object surface and including the exposed portion of the processing space 12) as another example. Or is provided. About the sealing material 14, this may be used also as a surface protective layer of the process target object 11, and in such a case, after construction, the seal material 14 is left as it is on the surface of the process target object 11.

  The epoxy resin two-component adhesive 21 used in the present invention is composed of a main agent 22 and a curing agent 23, and a mixture of the main agent 22 and the curing agent 23 at a predetermined ratio is used. Specifically, the main agent 22: curing agent 23 is mixed and used so as to be 2: 1. The mixing ratio in this case is a volume mixing ratio. There is an allowable error in the volume mixing ratio of the main agent 22 and the curing agent 23. It is less than ± 10% and desirably less than ± 5%. When the tolerance of the volume mixing ratio of both agents 22 and 23 is within this range, a predetermined effect reaction occurs and the adhesive 21 is cured. In the main agent 22 and the curing agent 23, the main agent 22 is referred to as A liquid and the curing agent 23 is referred to as B liquid.

  The epoxy resin two-component adhesive 21 will be further described in detail. Examples of the main agent 22 include bisphenol A type epoxy resin, bisphenol F type epoxy resin, bisphenol AD type epoxy resin, and novolak type epoxy resin. These may be used alone or in combination. Two typical examples are: the main agent 22 in the first example is composed of 100% bisphenol A type epoxy resin, and the second main component 22 is composed of 60 to 70% by weight of bisphenol A type epoxy resin and 10 to 20 pigments. It consists of 20% by weight and 20-30% by weight filler. For the curing agent 23, aliphatic amines, modified aliphatic amines, modified aliphatic polyamines and the like are used alone or in combination. The curing agent may contain an ether-based diluent. When the curing agent 23 is made to correspond to each of the specific main agents 22 described above, the curing agent 23 for the first main agent 22 is 45 to 55% by weight of an aliphatic amine and 20 to 30% by weight of a modified aliphatic amine. The curing agent 23 for the main agent 22 in the second example is composed of 90 to 100% of a modified aliphatic polyamine. About the epoxy resin type | system | group two-component adhesive 21, what adjusted the viscosity arbitrarily within the range of the viscosity of 30-30000 mPa * s (25 degreeC value, hereafter the same) is employ | adopted. In particular, in the adhesive 21, one having a viscosity of 30 to 1000 mPa · s is often used in order to improve fluidity and permeability into the processing space 12. Furthermore, in a typical example of the epoxy resin two-component adhesive 21 made of an epoxy resin two-component adhesive, the viscosity is 700 mPa · s. As such an epoxy resin type two-component adhesive 21, one that is cured in a temperature range around room temperature is often employed.

  The apparatus according to the embodiment of the present invention illustrated in FIGS. 1 to 2 is mainly composed of three pressure supply systems 31 a to 31 c and one mixing injector 41. This will be described in detail below.

  Referring to FIG. 1, three pressure supply systems 31 a to 31 c are provided on a housing 32 having a box-shaped structure, three pumps 33 a to 33 c mounted in the housing 32, and standing on the housing 32. Three legged support bases 36a to 36c, three raw material containers (tanks) 37a to 37c installed on the respective legged support bases 36a to 36c, a predetermined number of inflow supply pipes 39a to 39c, A predetermined number of outlet supply pipes 40a to 40c are configured. In this case, the pumps 33a to 33c and the raw material containers 37a to 37c are connected via inflow supply pipes 39a to 39c connected across the suction ports 34a to 34c of the pump 33a and the outlets 38a to 38c of the raw material containers 37a to 37c. The outlet supply pipes 40a to 40c are connected to the discharge ports 35a to 35c of the pumps 33a to 33c, respectively. In the above, the housing 32 is made of a known material such as metal, synthetic resin, or a composite material thereof. Although not shown, the housing 32 is equipped with power supply equipment (wiring connection means or a battery for commercial power supply) for each of the pumps 33a to 33c, and is necessary for each of the pumps 33a to 33c. It is equipped with a controller, gauge, alarm, pilot lamp, power switch, etc. that are desirable. As each pump 33a-33c, a well-known thru | or well-known thing can be arbitrarily employ | adopted for viscous fluid supply. In the illustrated example, a gear pump with good flow rate stability and flow rate controllability is employed as an example. Support bases 36a to 36c with legs, raw material containers 37a to 37c, supply pipes 39a to 39c for inflow, and supply pipes 40a to 40c for outflow are also made of known materials such as metal, synthetic resin, and composite materials thereof. However, the supply pipes 39a to 39c and 40a to 40c are made of such materials and structures when flexibility is required. The supply pipes 39a to 39c and 40a to 40c are also provided with cocks or valves (not shown) at their base end portions and / or front end portions.

  Referring to FIGS. 2A to 2C, the mixing and injection machine 41 includes a casing 42, a rotating body 55, and a drive machine 59. Of these, the casing 42 includes a cylinder 43, a bearing member 45 mounted on the base end side of the cylinder 43, a nozzle 49 mounted on the tip end side of the cylinder 43, and a body portion of the cylinder 43. It is comprised by three connection port tools 54a-54c with which an outer peripheral surface is mounted | worn. The cylinder 43 has an outer shape with a rectangular cross section and an inner shape with a circular cross section, and three connection ports 44a to 44c are formed in the body portion thereof. The three connection ports 44a to 44c are not opposed to each other because the positions in the axial direction and / or the positions in the radial direction are different from each other. The bearing member 45 has a flange 47 formed at the outer end of the hollow shaft 46 or a known seal member attached to the inner peripheral surface of the hollow shaft 46, and the axial movement of the rotating body 55. A thrust receiving plate 48 for restraining is provided on the surface on the flange 47 side. In the nozzle 49, a flange 51 is formed at the outer end of the hollow shaft 50, and a tapered nozzle cylinder 52 is formed to protrude from the center on the flange 51 side toward the front. In addition, a recessed channel portion 53 is formed on the inner end surface of the hollow shaft 50. Therefore, in the case of the nozzle 49, the passage portion 53, the axial hole of the hollow shaft 50, and the inside of the nozzle cylinder 52 are arranged in series. The three connection ports 54a to 54c are detachably attached to the connection ports 44a to 44c of the cylinder 43, and have flanges on their outer surfaces. Next, with regard to the rotating body 55, this is such that the rotating shaft 56 on the base end side, the screw shaft 57 on the center portion, and the stirring shaft 58 on the tip end portion are integrated in a straight line on the same axis. is there. As is well known, the screw shaft 57 has helical fins on the peripheral surface for imparting a swirling fluidity in a predetermined direction to a viscous body or the like. In the case of such a screw shaft 57, when the adhesive 21 (main agent 22 + curing agent 23) is fed and propelled in the casing 42, the spiral fin prevents the adhesive from flowing backward. . The agitation shaft 58 has an outer shape that can be accommodated in the nozzle cylinder 52, and irregularities having an agitation action are formed on the outer peripheral surface thereof. Incidentally, the stirring shaft 58 in the illustrated example has an elongated blade shape, and concave portions whose phases are alternately shifted are formed on both sides thereof. As such a stirring shaft 58, any stirring shaft 58 can be adopted as long as it has a stirring action. Therefore, a shaft having a large number of stirring protrusions formed on the outer peripheral surface of the shaft can also be used as the stirring shaft 58. On the other hand, as the drive machine 59, a machine that power-rotates the rotating body 55 is employed. One example is a well-known electric motor (electric motor), and another example is a well-known air motor. The drive machine 59 is connected to the rotating body 55 of the mixing injector 41 as described later. When this power transmission is performed remotely, a flexible shaft is used for connection for power transmission if it is an electric motor, and a long flexible air hose / air pipe is used for connection for power transmission if it is an air motor ( In the case of an air motor, an air rotation mechanism mounted on the rotating body 55 side and an air supply source disposed at a remote location are connected by an air hose / air pipe). In a normal case that is not so, the electric motor and the rotating body 55 are directly connected by a coupling, or the air rotating mechanism portion mounted on the rotating body 55 side and the air supply source disposed at a remote place are short. They are connected with hoses and pipes. Most of the materials for constituting the casing 42 and the rotating body 55 in the mixing injector 41 are made of metal except for a flexible material and a sealing material. It may be made of a synthetic resin with excellent mechanical strength and durability. As the drive machine 59, a commercially available product such as a commercial product is used.

  The mixing injector 41 described above is assembled as follows with reference to FIG. It is a disassembleable setup. Three connection ports 54 a to 54 c are attached to the three connection ports 44 a to 44 c of the cylinder 43 by screwing means using male screws and female screws. Specifically, the base end portions of the connection ports 54a to 54c are screwed into the connection ports 44a to 44c. The nozzle 49 is also attached to the distal end side of the cylinder 43 by screwing means using male and female screws. That is, the nozzle 49 is attached by screwing the hollow shaft 50 into the tip of the cylinder 43. In the case of the bearing member 45 and the rotating body 55, the thrust receiving plate 48 is provided on the rotating shaft 56 from the surface side of the hollow shaft 46 in a state where the rotating shaft 56 of the rotating body 55 passes through the hollow shaft 46 of the bearing member 45. Screwed. As a result, the end surface of the screw shaft 57 comes into contact with the inner end surface of the hollow shaft 46, so that the rotating body 55 is rotatably supported by the bearing member 45 without moving in the axial direction. The combined product of the bearing member 45 and the rotator 55 includes the rotator 55 such that the stirring shaft 58 of the rotator 55 is accommodated in the nozzle cylinder 52 of the nozzle 49 and the screw shaft 57 of the rotator 55 is accommodated in the cylinder 43. After the respective parts are inserted into the respective predetermined parts, the hollow shaft 46 of the bearing member 45 is screwed into the base end portion of the cylinder 43 by means of screwing means using male and female screws. The drive machine 59 is connected to the rotating shaft 56 of the rotating body 55 in any of the above-described manners. As shown in FIG. 1, three pressure supply systems 31a to 31c are connected to the mixed injector 41 thus assembled. That is, the supply system 31 a is connected to the connection port 54 a of the mixing injector 41, the supply system 31 b is connected to the connection port 54 b of the mixing injector 41, and the supply system is connected to the connection port 54 c of the mixing injector 41. 31c is connected. This connection example will be described in relation to the main agent 22 and the curing agent 23. The main agent 22 flows through the connection port 54a, the curing agent 23 flows through the connection port 54b, and the main agent 22 flows through the connection port 54c. . This is because the main agent 22 having a relatively high viscosity flows in the mixing injector 41 and the curing agent 23 having a relatively low viscosity flows in the rear of the mixing injector 41, so that the back flow of both agents 22 and 23 occurs. This is a difficult connection example. However, the curing agent 23 may flow through the connection port 54a and the main agent 22 may flow through the other two connection ports 54b and 54c depending on the viscosity of the two agents 22 and 23 and other conditions. The agent 23 may flow through the connection port 54c, and the main agent 22 may flow through the other two connection ports 54a and 54b.

  What is employed as the suction machine 62 in the suction system 61 illustrated in FIG. 1 is known or well-known. A suction machine 62, which is a main component in the suction system 61, includes a suction tank 65 having a suction port 63 and a discharge port 64, a suction fan (not shown), its power source (not shown), and a filter (see FIG. Not shown), a pressure gauge (not shown), and the like. Another component of the suction system 61 is a relay tank 68 having a suction port 66 and a discharge port 67. The relay tank 68 is provided with a filter (not shown). The suction port 63 of the suction tank 65 and the discharge port 67 of the relay tank 68 are connected to each other via a hose (secondary flexible hose) 69, and the discharge port 67 of the relay tank 68 is connected to the tip. A hose (primary side flexible hose) 71 having a flange joint type connector 70 is connected. The material of each component in the suction system 61 is publicly known or well known. Incidentally, the suction tank 65 and the relay tank 68 are made of metal, synthetic resin, or composite material. In such a suction system 61, the relay tank 68 and the hose 69 are omitted, and the hose 71 with the connection tool 70 may be directly connected to the suction port 63 of the suction tank 65. The hose 71 may be transparent in order to visually recognize that the adhesive 21 has reached the inside. In addition, the connection tool 70 may be omitted from the tip of the hose 71. Even in such a case, the tip of the hose 71 is hermetically connected to a predetermined portion (the communication passage 13 of the processing object 11) with an adhesive or the like.

  When the present invention construction method is carried out using the apparatus of the present invention illustrated in FIGS.

  1-2, when pre-processing the processing space 12 of the processing object 11, a suction system 61 is used. For this purpose, the following work is performed. First, the communication path 13 is formed in the processing object 11 so as to communicate with the processing space 12. Specifically, the communication passage 13 is formed in an inclined shape from the surface of the processing object 11 to the inside thereof through a hole drill such as an electric drill. By doing so, the communication passage 13 crosses the two processing spaces 12 and leads to these even if there is only one. Next, on the surface of the processing object 11, the exposed portion of the processing space 12 is surrounded and the portion is covered with the sealing material 14. Specifically, a film-like or sheet-like sealing material 14 having an adhesive layer or an adhesive layer on the inner surface is attached to a corresponding portion on the surface of the object to be processed to cover the exposed portion of the processing space 12. As a result, the processing space 12 and the communication passage 13 of the processing object 11 are kept airtight with respect to the outside of the processing object 11.

  The work after such pre-processing is as follows. First, as shown in FIG. 1, the nozzle 49 of the mixing injector 41 is connected to the lower end of the processing space 12 on the surface of the processing object 11. Specifically, after a part of the sealing material 14 is drilled or excised to expose the end of the processing space 12, the tip of the nozzle 49 is inserted therein and this state is maintained. Alternatively, a connection port for connection is attached to the exposed end portion of the processing space 12, and the tip end portion of the nozzle 49 is inserted therein to hold this state. Thereafter, the pumps 33a to 33c are driven to start the supply of the main agent 22 and the curing agent 23 by the supply systems 31a to 31c, and the rotating body 55 of the mixing injector 41 is rotated via the drive machine 59. Let As a result, the main agent 22 and the curing agent 23 are changed into the raw material containers 37a to 37c → inflow supply pipes 39a to 39c → pumps 33a to 33c → outflow supply pipes 40a to 40c → connection ports 44a to 44c (connection ports 54a to 54c). ) → Introduced up to the mixing injector 41 through the route of the mixing injector 41 and stirred and mixed in the mixing injector 41.

  Regarding the main agent 22 and the curing agent 23 in the above, the supply system of the main agent 22 is two systems 31a and 31c, and the supply system of the curing agent 23 is only one system 31b. In this case, the supply amounts of the supply systems 31a to 31c are equal. Therefore, the main agent 22 and the curing agent 23 flow into the mixing injector 41 at a ratio of main agent: curing agent = 2: 1. In the case of the supply systems 31a to 31c in which the respective conditions are equal to each other, inflows are not hindered because the forces of each other are balanced. In addition, when the three connection ports 44a to 44c are not opposed to each other, this kind of inflow inhibition is further difficult to occur. As a result, both agents 22 and 23 can be stably supplied to the mixing / injecting machine 41 that receives the reaction force during the injection of the adhesive. In the mixing / injecting machine 41, the main agent 22 and the curing agent 23 that have flown into the mixing / injecting device 41 are fed to the nozzle 49 side while being primarily stirred and mixed by the screw shaft 57, and the nozzle 49 also receives the secondary via the stirring shaft 58. Stir and mix. Furthermore, the screw shaft 57 prevents the backflow of the adhesive 21 (main agent 22 + curing agent 23) in the casing 42. Therefore, the adhesive 21 mixed and prepared by the mixing / injecting machine 41 is finished into a mixture in which the main agent 22 and the curing agent 23 are homogeneously mixed, and the processing of the processing object 11 from the tip portion of the nozzle 49 without backflow. It is injected and supplied into the spaces 12, and each processing space 12 and the communication passage 13 are filled with the adhesive 21.

  In the embodiment of FIG. 1, when each space of the processing object 11 such as the processing space 12 or the communication passage 13 is filled with the adhesive 21 as described above, the subsequent measures are different for each embodiment. As one embodiment, when the suction system 61 is connected to the communication passage 13 in the operating state, the adhesive 21 sucked after being filled flows into the hose 71 or in the relay tank 68. Or flow into. Therefore, at this time, the pump pumps 33a to 33c of the supply systems 31a to 31c, the drive machine 59 of the mixing and injection machine 41, the suction machine 62 of the suction system 61, and the like are stopped. By the way, when the hose 71 is transparent, the operator visually recognizes the inflow of the curable material into the hose 71 and stops the above devices. Further, when a flow sensor is provided in the hose 71 and / or the relay tank 68, the above-mentioned devices are automatically stopped by detecting the inflow of the adhesive 21 by this sensor. Usually the latter is often the case. As another embodiment, when the suction system 61 is removed from the processing object 11 before the adhesive 21 is injected, the overflow of the adhesive 21 from the end of the communication passage 13 is visually recognized or detected by a sensor. Stop each of the above devices. When the suction system 61 is not used as another embodiment, the above-mentioned devices are stopped by visually observing or detecting the overflow of the adhesive 21 from one of the plurality of processing spaces 12.

  When the filling process of the processing space 12 with the adhesive 21 is completed in the above-described embodiment, the mixed injector 41 or the mixed injector 41 and the suction system 61 may be removed from the processing object 11. After the adhesive 21 is cured, post processing is performed as necessary. For example, post processing such as finishing the surface of the processing object 11 to erase the trace is performed. The sealing material 14 is either left on the surface of the processing object 11 or removed from it. Incidentally, the sealing material 14 is removed from the surface of the processing object 11 except when this is left as a surface protective layer. The trace when the sealing material 14 is removed may be surface-finished as described above.

In the above, when the epoxy resin type two-component adhesive 21 used is of a type that cures at room temperature (20 ° C.), a used amount of 0.12 kg / m ² is cured by curing for 4 to 24 hours. When the adhesive 21 is thermosetting, heat curing may be promoted by applying a surface heater such as an electrothermal type to the surface of the processing object 11 or blowing hot air or hot air.

  In the embodiment of FIG. 1, when the adhesive 21 is supplied into the processing space 12 of the processing object 11, this may be performed a plurality of times. An example of this is where the forgotten seal, difficult to seal, or crack that cannot be detected are present in the processing object 11 and a part of the processing space 12 communicates with the outside at a site without the seal, and the adhesive 21 leaks from there. This is the case. In such a case, after the first supply of the adhesive 21 to the processing space 12 is finished, it waits for it to gel 50% or more, or waits for it to be completely cured, and then the second and subsequent times. Supply.

  The apparatus illustrated in FIGS. 3 to 4 of the apparatus of the present invention is mainly composed of three pressure supply systems 31a to 31c and one mixing injector 41. The supply system 31 is different from the previous example. This will be described below.

  The three types of pressure supply systems 81 a to 81 c illustrated in FIGS. 3 to 4 include a table-type support base 82, arcuate cylindrical holding members 86 a to 86 c, struts 87 a to 87 c, a mounting plate 88, and a telescopic machine 89. The pressure plate 93, the human-powered pump 94, the telescopic material containers 99a to 99c, the outflow supply pipes 101a to 101c, and the like are constituent elements.

  Referring to FIG. 4A, a support base 82 includes a base plate 84 in which openings 83a to 83c are formed where the vertices of a virtual equilateral triangle are located, and four legs that can be understood from FIG. 85 (four legs 85 projecting downward from the bottom corners of the base plate 84). Each arcuate cylindrical holding member 86a to 86c has a circumferential slit formed in its peripheral surface. The holding members 86 a to 86 c are concentric with the openings 83 a to 83 c on the base plate 84 of the support base 82, and the slits of the holding members 86 a to 86 c face the center of the base plate 84. It is fixed upright. The three struts 87a to 87c are vertically fixed on the base plate 84 of the support base 82 in a three-point arrangement interposed between the openings 83a to 83c. The mounting plate 88 is constructed integrally with these on the columns 87a to 87c. A telescopic machine 89 composed of a well-known air cylinder is mainly composed of a cylinder 90, a piston 91, a piston rod 92, and the like, and a pressure plate 93 is attached to the tip of the piston rod 92. In this case, as shown in FIG. 4B, the pressure plate 93 has a three-way radial shape in which a circular plate portion is connected to each vertex of the triangular plate portion. Referring to FIG. 3, the expansion / contraction machine 89 with the pressure plate 93 is attached to the lower surface of the mounting plate 88 while maintaining the direction in which the pressure plate 93 is the lower side. The pressure plate 93 attached to the expansion / contraction machine 89 and the holding members 86a to 86c are the pressure plate 93 when the expansion plate 89 is lowered by the extending operation of the expansion / contraction machine 89. There is a relative relationship of intervening inside. The manually operated pump 94 is for supplying and exhausting air into the cylinder 90 of the telescopic machine 89. This consists of a known hand pump (hand pump) or a known foot pump (foot pump). The main components of the pump 94 are a main body 95 having a control valve and a stop valve, an operation section 96 for supplying and exhausting air, two hoses 97 and 98 connected to predetermined portions of the main body 95, and the like. The two hoses 97 and 98 in the pump 94 are connected to the cylinder 90 of the telescopic machine 89 as shown in FIG. With reference to FIG.4 (C), the expansion-contraction type raw material containers 99a-99c depend on a bellows structure, and a trunk | drum expands-contracts in a length direction. A mouth portion 100 for entering and exiting the adhesive is provided at the front end surfaces of these raw material containers 99a to 99c. The raw material containers 99a to 99c have outer diameters and heights that are received and held in the holding members 86a to 86c in conformity with the holding members 86a to 86c. About each raw material container 99a-99c, what put the main ingredient 22 or the hardening | curing agent 23 is loaded in each holding member 86a-86c in the state which faced the opening part 100 downward. In this case, the mouth portions 100 of the raw material containers 99a to 99c protrude from the openings 83a to 83c of the base plate 84 below the base plate 84. At the same time, the pressure plate 93 can press and press the raw material containers 99a to 99c from the upper side. Each of the supply pipes 101a to 101c for outflow has a cap-shaped connector (not shown) at the base end portion thereof, and has either a cock valve (not shown) near the base end portion and / or the tip end portion thereof. It is. As shown in FIG. 3, each of the supply pipes 101a to 101c for outflow has a connector provided on the base end side (with an internal thread on the inner peripheral surface) and the mouth part 100 (with an external thread on the outer peripheral surface). Are connected to the respective raw material containers 99a to 99c by screwing, and the respective front ends thereof are directly connected to the connection ports 54a to 54c, or indirectly connected by a connecting jig, The mixing injector 41 is also connected.

  As parts and members for constituting the three types of pressure supply systems 81a to 81c, a hard and strong material or a soft and strong material can be used. Incidentally, the support base 82 is made of metal, hard synthetic resin, wood, or a composite thereof. Each holding member 86a-86c, each support | pillar 87a-87c, the attachment plate 88, the pressurizing plate 93, etc. consist of either these, a hard synthetic resin, or these composites. The telescopic machine 89 and the pump 94 are ready-made products (commercial products). Each of the raw material containers 99a to 99c is made of a soft and tough material such as soft rubber or soft synthetic resin. The hoses 97 and 98, the outflow supply pipes 101a to 101c, and the like are made of flexible rubber, synthetic resin, metal, or the like. In this case, it is desirable that the portions of the supply pipes 101a to 101c for the outflow except for the connectors are soft, and it is desirable that the connectors are hard.

  When implementing the method of the present invention using the apparatus of the present invention illustrated in FIGS. 3 to 4, there is basically no difference from the previous example except for the operation of the pressure supply systems 81 a to 81 c. This will be described below.

  In the method of the present invention using the device of the present invention shown in FIGS. 3 to 4, the pretreatment of the treatment space 12 of the treatment object 11 via the suction system 61 may be the same as the previous example, or this may be omitted. Covering the exposed portion of the processing space 12 with the sealing material 14 on the surface of the processing object 11 is the same as the previous example. For each of the raw material containers 99a to 99c, as a typical example, the raw material container 99b contains the curing agent 23, and the raw material containers 99a and 99c contain the main agent 22, respectively. It is the same as in the previous example that the nozzle 49 of the mixing injector 41 is connected to the lower end of the processing space 12 on the surface of the processing object 11. Thereafter, the pump 94 is operated by the operation unit 96 to supply or exhaust air to the cylinder 90 of the expansion / contraction machine 89. Specifically, air is introduced into the upper part of the cylinder 90 via the hose 97 and simultaneously air is extracted from the lower part of the cylinder 90 via the hose 98. As a result, the piston 91 is lowered while the piston rod 92 is pushed down, and the pressure plate 93 on the rod tip side compresses the raw material containers 99a to 99c. As a result, the main agent 22 and the curing agent 23 are routed through the raw material containers 99a to 99c → the mouth portion 100 → the outflow supply pipes 101a to 101c → the connection ports 44a to 44c (connection ports 54a to 54c) → the mixing injector 41. The mixture is introduced up to the mixing injector 41 and stirred and mixed in the mixing injector 41. Further, as in the previous example, the main agent 22 and the curing agent 23 that have flowed into the mixing / injecting machine 41 are fed to the nozzle 49 side while being primarily stirred and mixed by the screw shaft 57, and also in the nozzle 49 through the stirring shaft 58. Next, the mixture is stirred. Therefore, the adhesive 21 mixed and prepared by the mixing / injecting machine 41 is finished into a mixture in which the main agent 22 and the curing agent 23 are homogeneously mixed. The adhesive 21 enters the processing space 12 of the processing object 11 from the tip of the nozzle 49. By injecting and supplying, the inside of each processing space 12 and the inside of the communication passage 13 are filled with the adhesive 21. Since the following is substantially the same as or equivalent to the previous example, the description is omitted.

  When raising the pressure plate 93 in the embodiment of FIGS. 3 to 4, the pump 94 is operated after switching the air flow path. That is, air is introduced into the lower part of the cylinder 90 via the hose 98 and simultaneously, air is extracted from the upper part of the cylinder 90 via the hose 97. As a result, the piston 91 rises and the piston rod 92 is pulled up, so that the pressure plate 93 also rises.

  In the embodiment shown in FIGS. 3 to 4, the manual operation pump 94 may be a hand-operated or foot-operated hydraulic pump. When the pump 94 is a hydraulic system, the telescopic machine 89 is also changed to a hydraulic system. The manual operation pump 94 may be changed to an electric power pump (hydraulic pump or pneumatic pump). Furthermore, in the embodiment in which a weight (weight) is placed on the pressure plate 93 and the raw material containers 99a to 99c are compressed with the weight, the telescopic machine 89 and the pump 94 can be omitted. In addition, when the openings 83a to 83c of the base plate 84 have a diameter slightly larger than the outer diameter of the raw material containers 99a to 99c, the raw materials are put into the holding members 86a to 86c from the lower surface side of the base plate 84. Containers 99a-99c can be loaded. However, in this case, in order to prevent the raw material containers 99a to 99c from dropping, for example, a drop-off preventing member having an appropriate shape such as a bifurcated shape, a U shape, or a ring shape is used as the upper surface of the base plate 84 and the lower surface of the raw material containers 99a to 99c ( It is interposed between the tip surface).

  The method of the present invention and the device of the present invention have high industrial applicability because they can satisfy the accurate blending of the adhesive, the uniform mixing of the adhesive, the stable operation of the mechanical device and the cost reduction.
