Abstract

PROBLEM TO BE SOLVED: To provide an adhesive structure and an adhesion method, using two types of adhesives for bonding members to be joined to each other, allowing the adhesives to exhibit the individual effects without impairment.SOLUTION: An adhesive 10 encapsulated in a container includes a first cylindrical part 111 having a closed space 117 in which a first adhesive 12 is encapsulated, a second cylindrical part 112 having a closed space 123 in which a second adhesive 13 is encapsulated, and an inclined part 113 lying therebetween. When the adhesive 10 encapsulated in a container is set in a mortise 6 and a tenon 7 is penetrated thereinto, the sidewall is broken due to increased internal pressure of individual closed spaces. The first and second adhesives flow out from the broken points, so that the inner surface of the mortise is sequentially applied with the adhesives. The tenon is thereby bonded to the mortise. The inclined part is contacted with a step part 63 of the mortise, functioning as a separator. Consequently the first adhesive and second adhesives spilled out are prevented from being mixed, allowing the adhesives to exhibit the individual effects without impairment.

Description

The present invention relates to a container-sealed adhesive in which an adhesive is sealed in a container and an adhesive method for bonding members together using the same.

Adhering members to be joined together with an adhesive has been widely practiced. For example, in construction of a building, a convex portion (tenon, dowel, etc.) formed on the other member is fitted to a concave portion (mortise, dowel hole, etc.) formed on one member, and these are joined with an adhesive. Is done. Bonding with an adhesive can be performed without requiring skill compared to fixing with screws or screws, and is therefore more important at present when the shortage of carpenters is becoming more serious.

Patent Document 1 describes that a container-sealed adhesive is used as such an adhesive. In this prior art, two types of adhesives, an instant adhesive having an immediate effect and a normal woodworking adhesive, are used as an adhesive for fitting and bonding a tenon to a mortise. Prepared as a container-filled adhesive in which the agent is sealed in a container in advance, and inserted into the mortise with these in the mortise, it is sandwiched between the tip of the mortise and the bottom of the mortise. In addition, the two container-enclosed adhesives both rupture and the internal adhesive flows out, giving the initial adhesive force by the instantaneous adhesive and giving the impact resistance by gradually hardening the woodworking adhesive. ing.

As described in Patent Document 1, the adhesive for woodworking is excellent in the effect of maintaining the joined state even when subjected to an impact when cured, but on the other hand, there is a drawback that it takes a long time to cure In order to make up for this drawback, it is an effective technique to use an instant adhesive having an immediate effect.

However, according to the prior art described in Patent Document 1, when the tenon is inserted into the mortise and the container for enclosing the individual adhesives is destroyed, these adhesives are mixed together at the bottom of the mortise. End up. As is well known, instant adhesives are mainly composed of cyanoacrylate, which is polymer-cured with a small amount of moisture contained in the component, while woodworking adhesives are mainly composed of vinyl acetate emulsion, which are mixed together. Otherwise, the original performance may not be fully exhibited.

Therefore, the problem to be solved by the present invention is to use two types of adhesives to bond the members to be joined together, and to perform the respective adhesives without losing the original performance. It is to provide an agent structure.

Further, the problem to be solved by the present invention is that the members can be easily and stably fixed through the original performance of each adhesive by bonding the members to each other using such an adhesive. It is to provide a bonding method.

In order to solve this problem, in the present invention according to claim 1, a recess is formed in which a recess on the back side and an opening-side recess having an inner dimension larger than the recess on the back side are continuous in the axial direction via a stepped portion.

FIG. 1 is a front view (a), a plan view (b), a bottom view (c), a left side view (d), a right side view (e), and a container enclosing adhesive 10 according to an embodiment of the present invention. FIG. 2 is a rear view (f), FIG. 2 is a cross-sectional view taken along line AA in FIG. 1 (b), and FIG. 3 is a cross-sectional view taken along line BB in FIG. This container-enclosed adhesive 10 has a vertical frame 2, 3 and a horizontal frame 4, 5 of the window frame 1 (FIG. 4) formed by framing the left and right vertical frames 2, 3 and the upper and lower horizontal frames 4, 5. Used to connect at the four corners. Hereinafter, the front of the horizontal frame 4 is inserted into the mortise 6 on the inner surface of the upper end of the vertical frame 2 by using the container-containing adhesive 10 at one of the connection portions (the connection portion connecting the vertical frame 2 and the horizontal frame 4). A description will be given of fitting and joining the tenon 7 on the left side of the view. Bonding at other connecting portions can be performed in the same manner.

As shown in FIG. 5 which is a cross-sectional view of the connecting portion, a mortise 7 formed on the left end of the horizontal frame 4 is fitted in the mortise 6 formed on the inner surface of the upper end of the vertical frame 2. Thus, the mortise 6 and the mortise 7 are formed to have complementary shapes that enable this fitting. In this embodiment, the tenon 7 has a small-diameter portion 71 on the distal end side and a large-diameter portion 72 on the proximal end side through an inclined portion or stepped portion 73, and the distal end of the distal-side small diameter portion 71 is flat. A front end surface 74 is provided. A stepped portion 75 corresponding to the difference in diameter is formed between the proximal-side large-diameter portion 72 and the horizontal frame 4 main body.

On the other hand, the mortise 6 has a back-side small-diameter recess 61 corresponding to the distal-side small-diameter portion 71 of the tenon 7 and an opening-side large-diameter recess 62 corresponding to the proximal-side large-diameter portion 72 of the tenon 7. It is formed through a stepped portion 63 corresponding to the dimensional difference, and the bottom surface of the back side small-diameter concave portion 61 is a flat bottom surface 64.

The inner diameters of the rear-side small-diameter recess 61 and the opening-side large-diameter recess 62 of the mortise 6 are formed to be slightly larger than the outer diameters of the distal-side small-diameter portion 71 and the proximal-side large-diameter portion 72 of the mortise 7, respectively. The axial length of the mortise 7 combined with the proximal-side large-diameter portion 72 and the inclined portion 73 is substantially the same as the axial length of the opening-side large-diameter recess 62 of the mortise 6, The axial length of the back side small-diameter recess 61 is formed larger than the axial length of the distal-side small diameter portion 71 of the tenon 7.

Since the mortise 6 and the mortise 7 have the shapes and dimensions described above, the mortise 7 is inserted into the mortise 6 to the innermost position, and between the bottom face 64 of the mortise 6 and the tip face 74 of the mortise 7. A gap S1 is formed in accordance with the axial length difference between the back side small diameter recess 61 of the mortise 6 and the tip side small diameter part 71 of the mortise 7, and the step portion 63 of the mortise 6 and the inclined portion of the mortise 7 are formed. A gap S <b> 2 having a triangular cross section is formed in a ring shape. The gap S1 is filled with an adhesive that provides long-term fixing strength, and the gap S2 is filled with an instantaneous adhesive having immediate effect. With these adhesives, the vertical frame 2 and the horizontal frame 4 are firmly joined together with the tenon 7 fitted in the tenon hole 6.

A container-enclosed adhesive 10 used for obtaining such a connection structure will be described with reference to FIGS. The container 11 of the container-enclosed adhesive 10 has a shape that fits into the tenon 7 and the tenon hole 6 described above. The first cylindrical portion 111 that is fitted to the dent 10 and fitted to the rear-side small-diameter recess 61 of the mortise 6 and the proximal-end large-diameter portion 72 of the mortise 7 and the opening of the mortise 6 A second cylindrical portion 112 fitted into the side large-diameter concave portion 62 is integrally formed via an inclined portion 113 corresponding to the difference in diameter.

In other words, the first tubular portion 111 has an outer dimension corresponding to a slight dimensional difference between the outer dimension of the distal-side small-diameter part 71 of the tenon 7 and the inner dimension of the inner-side small-diameter recessed part 61 of the tenon hole 6. The second cylindrical portion 112 has an outer dimension corresponding to a slight dimensional difference between the outer dimension of the proximal end side large diameter part 72 of the tenon 7 and the inner dimension of the opening side large diameter recessed part 62 of the tenon hole 6. And each can be located sandwiched between them.

Both ends of the first cylindrical portion 111 in the axial direction are closed by a front wall 114 and a rear wall 115, and the first adhesive 12 is enclosed in the first closed space 117 formed by the side wall 116 and the front and rear walls 114, 115. ing. The front wall 114 has a large protrusion 118 protruding toward the first closed space 117, and the rear surface 115 is a small protrusion 119 protruding toward the side opposite to the first closed space 117 (second cylindrical portion 112 side). Have

The dimension of the 1st cylindrical part 111 is demonstrated. The outer diameter of the first cylindrical portion 111 is substantially the same as the inner diameter of the rear-side small-diameter recess 61 of the mortise 6, and the inner diameter is substantially the same as the outer diameter of the distal-side small-diameter portion 71 of the tenon 7. Further, the axial length of the first cylindrical portion 111 is formed to be shorter than the distal end side small diameter portion 71 of the tenon 7.

One end of the second cylindrical portion 112 (the end opposite to the inclined portion 113) is open, and the tenon 7 can be inserted from the opening end 120. A substantially semi-elliptical inner wall 122 is formed. An interval L (FIG. 2) between locations where the inner walls 122 are closest to each other is substantially the same as or slightly larger than the outer diameter of the distal-side small diameter portion 71 of the tenon 7, but the outer diameter of the proximal-side large diameter portion 72. Formed smaller. The second adhesive 13 is sealed in the second closed space 123 formed by the side wall 121 and the inner wall 122 of the second cylindrical portion 112.

In this embodiment, a partition wall 124 is provided that divides the second closed space 123 into four at intervals of 90 degrees, and the second adhesive 13 is placed in each of the four second closed spaces 123 divided by the partition wall 124. Although it is sealed, the second adhesive 13 may be sealed in one second closed space 123 over the entire circumference without providing the partition wall 124, or a plurality of second closed spaces 123 may be intermittently formed. The second adhesive 13 may be encapsulated in each of them.

The dimension of the 2nd cylindrical part 112 is demonstrated. The outer diameter of the second cylindrical portion 112 is substantially the same as the inner diameter of the opening-side large-diameter recess 62 of the mortise 6, and the inner diameter is substantially the same as the outer diameter of the proximal-side large-diameter portion 72 of the tenon 7. Further, the axial length of the second cylindrical portion 112 is substantially the same as that of the proximal end side large diameter portion 72 of the tenon 7. The inclined portion 113 has substantially the same inclination angle and axial length as the inclined portion 73 of the tenon 6.

In this embodiment, the first adhesive 12 is an adhesive for woodwork that exhibits a long-term fixing strength (for example, the one mainly composed of the vinyl acetate emulsion described in relation to the prior art). As the adhesive 13, an instant adhesive having an immediate effect (for example, one having cyanoacrylate as a main component as described above in relation to the prior art) is used.

The container 11 is made of a material (for example, a synthetic resin thin film material such as high-density polyethylene) that can be slightly plastically deformed and has a property of being easily broken when a pressure of a certain level or more is applied. Is preferred. The wall thickness of each part of the container 11 may be the same, but it is preferable to make the side wall 116 of the first cylindrical part 111 and the side wall 121 of the second cylindrical part 112 thinner than the wall thickness of other parts (FIG. 2). The reason for this will be described later.

Next, using this container-enclosed adhesive 10, the tenon 7 formed on the left end of the horizontal frame 4 is fitted and joined to the tenon 6 formed on the inner surface of the upper end of the vertical frame 2. Referring to FIGS. 6 to 8, a description will be given of a work process when obtaining a connection structure as shown in FIG. 5.

First, the container-containing adhesive 10 is fitted into the mortise 6 of the vertical frame 2 and set. As described above, the container 11 of the container-enclosed adhesive 10 is firmly fitted in the first cylindrical portion 111 and the opening-side large-diameter recess 62 that can be tightly fitted in the back-side small-diameter recess 61 of the mortise 6. And the axial length of the second cylindrical portion 112 and the inclined portion 113 together is the axial length of the opening-side large-diameter concave portion 62 of the mortise 6. Since they are formed substantially the same, the container-sealed adhesive 10 can be set in a state of being closely fitted and housed inside the mortise 6 (FIG. 7A).

The mortise 7 is inserted from the open end 120 of the container-filled adhesive 10 set in the mortise 6 in this way (FIG. 7A). As described above, the distance L (FIG. 2) between the locations where the inner walls 122 are closest to each other is formed to be substantially the same as or slightly larger than the outer diameter of the distal end side small diameter portion 71 of the tenon 7. The tip-side small diameter portion 71 of the tenon 7 smoothly passes through the second cylindrical portion 112 of the container 11, and at this time, the second adhesive 13 accommodated in the second closed space 123 of the second cylindrical portion 112. Is substantially free of pressure. FIG. 7A shows that the tip-side small diameter portion 71 of the tenon 7 passes through the second cylindrical portion 112 of the container 11 in this way, and the tip surface 74 of the tenon 7 is formed on the small protrusion 119 of the container rear wall 115. The state which reached | abutted has been shown.

When the tenon 7 is further pushed in from this state, the front end surface 74 of the tenon 7 pushes the small projection 119 to flatten the rear wall 115 and further presses the rear wall 115 to accommodate the first adhesive 12. The space 117 is compressed (FIG. 7B). The large protrusion 118 formed on the front wall 114 prevents the front wall 114 from being deformed at this time, and does not release the pressurizing force of the tenon 7 to the front wall 114 side. It works to achieve effective compression by increasing the internal pressure.

As described above, since the side wall 116 is formed thinner than the front wall 114 and the rear wall 115, the side wall 116 is broken by the increase in the internal pressure of the first closed space 117 due to the pushing of the tenon 7, and is accommodated inside. One adhesive 12 flows out from the broken portion of the side wall 116 (FIG. 7C). At this time, the tip side small diameter portion 71 of the mortise 7 has already entered the back side small diameter recess 61 of the mortise 6, and the inclined portion 113 is an angle between the back side small diameter recess 61 of the mortise 6 and the step portion 63. The first adhesive 12 that has flowed outward from the first closed space 117 does not flow into the opening-side large-diameter recess 62, but closes to the opening-side large-diameter recess 62. It is efficiently applied to the inner surface of the side small-diameter recess 61 (indicated by a black line).

As the tenon 7 is pushed, the torn portion of the side wall 116 also moves gradually in the pushing direction, so that the first adhesive is gradually applied to the inner surface of the back side small-diameter recess 61 (FIG. 7D). ). In this way, the mortise 7 is located at the innermost position of the mortise 6 (the step portion 75 is in close contact with the inner surface of the vertical frame 2 around the mortise 6, and the distal end side small diameter portion 71 is completely in the back side small diameter recess 61 of the mortise 6. The first adhesive 12 that has flowed out is sufficiently applied over the axial length on the inner surface of the small-diameter recess 61 on the back side of the mortise 6, and this first adhesion is reached. The distal end side small diameter portion 71 of the tenon 7 is adhered to the back side small diameter concave portion 61 of the mortise 6 with the agent 12 (FIG. 8).

In addition, although the inclined part 113 and the rear wall 115 are maintained in a continuous state at the time of FIG. 7 (c), if the mortise 7 is further pushed toward the back of the mortise 6 from here, the mortise Since stress concentrates on a portion (for example, a midway portion of the inclined portion 113) that hits the corner between the rear side small-diameter concave portion 61 and the step portion 63, the inclined portion 113 is torn at this portion. As a result, the rear wall 115 (and a part of the inclined portion 113) cut off at the tearing portion is pushed by the distal end surface 74 of the tenon 7 and pushed into the depth of the tenon hole 7, and the state shown in FIG. Become.

Fragments 111 ′ (including the crushed front wall 114 and rear wall 115) of the first tubular portion 111 that are generated by the side wall 116 being torn gradually move in the same direction by the tenon 7 being pushed, Finally, the tenon 6 is accommodated in the gap S1 (FIG. 5) formed by the axial length dimensional difference between the back side small diameter recess 61 of the mortise 6 and the tip side small diameter part 71 of the mortise 7. This will not interfere with pushing the to the farthest position. Further, at this time, the broken pieces 111 ′ of the first cylindrical portion 111 are almost entirely attached with the first adhesive 12, so that the tenon end face 71 is bonded to the mortise bottom face 64 through this. The effect can also be expected.

On the other hand, when the tenon 7 is pushed to the position of FIG. 7B, the inclined portion 73 of the tenon 7 also enters the opening end 120, so that the second adhesive 13 is accommodated by pushing the inner wall 122 of the second cylindrical portion 112. The second closed space 123 is compressed (FIG. 7B). Since the side wall 121 is formed thinner than the inner wall 122 as described above, the side wall 121 is broken by the increase in the internal pressure of the second closed space 123 due to the pushing of the tenon 7, and the second adhesive 13 accommodated therein is It flows out from the torn part of the side wall 121 (FIG. 7C). At this time, the proximal-side large-diameter portion 72 of the mortise 7 has already entered the opening-side large-diameter recess 62 of the mortise 6, and the inclined portion 113 is formed between the back-side small-diameter recess 61 of the mortise 6 and the step portion 63. Since the gap leading to the back side small-diameter recess 61 is closed in close contact with the corner, the second adhesive 13 that has flowed outward from the second closed space 123 may leak out from the opening end 120. It is efficiently applied to the inner surface of the opening-side large-diameter recess 62 without flowing into 61 (indicated by a black solid band).

As the tenon 7 is pushed, the torn portion of the side wall 121 is also gradually moved in the pushing direction, so that the second adhesive 13 is gradually applied to the inner surface of the opening-side large-diameter recess 62 (FIG. 7 ( d)). When the mortise 7 reaches the deepest position of the mortise 6 in this way, the second adhesive 13 that has flowed out is sufficiently applied over the axial length on the inner surface of the opening-side large-diameter recess 62 of the mortise 6. The base end side large-diameter portion 72 of the tenon 7 is bonded to the opening-side large-diameter concave portion 62 of the mortise 6 with the second adhesive 13 (FIG. 8).

The fragments 112 ′ (including the crushed inner wall 122, the partition wall 124, and the wall of the inclined portion 113) of the second cylindrical portion 112 generated by the side wall 121 being torn gradually in the same direction by the tenon 7 being pushed. And is finally accommodated in the gap S2 (FIG. 5) between the step portion 63 of the mortise 6 and the inclined portion 73 of the mortise 7, so that the mortise 6 is pushed to the deepest position. There will be no hindrance. Further, at this time, the broken piece 112 ′ of the second cylindrical portion 112 is almost entirely attached with the second adhesive 13, so that the inclined portion 73 of the tenon 7 is formed in the step of the mortise 6 through this. The effect of adhering to the part 63 can also be expected.

As understood from the above description, the first closed space 117 in which the first adhesive is sealed in the first cylindrical portion 111 of the container-filled adhesive 10 in the middle of pushing the tenon 7 into the mortise 6. And the second closed space 123 that encloses the second adhesive in the second cylindrical portion 112 are compressed and ruptured almost simultaneously, so that the internal first adhesive 12 and the second adhesive 13 flow out almost simultaneously. However, the inclined portion 113 of the container 11 serves as a separator to prevent the first adhesive 12 and the second adhesive 13 from being mixed with each other. Therefore, different components and foreign matters are used as in the case where a long-term fixing adhesive mainly composed of vinyl acetate emulsion is used for the first adhesive 12 and an instantaneous adhesive mainly composed of cyanoacrylate is used for the second adhesive 13. Even in the case of using an adhesive, it is possible to prevent the performance from being deteriorated by mixing them and to exhibit their original performance.

8 shows substantially the same state as that in FIG. 5, but the application state of the first adhesive 12 and the second adhesive 13, and each of the first cylindrical portion 111 and the second cylindrical portion 112. Fragments 111 ′ and 112 ′ after rupture are also shown, and are more detailed than FIG. In FIG. 5, these are omitted and simplified. The 1st adhesive agent 12 and the 2nd adhesive agent 13 are shown by the solid black line in FIG.

Although the above-described method of joining and fixing the tenon 7 of the horizontal frame 4 to the tenon hole 6 of the vertical frame 2 using the container-enclosed adhesive 10 has been described above, as shown in FIG. When joining the horizontal frame 4 via the dowels 8, a pair of the container-enclosed adhesives 10 may be used. In this case, the mortise 6 formed in the inner surface of the upper end of the vertical frame 2 becomes a dowel hole 6, and a similar dowel hole 9 is formed at the joining end of the horizontal frame 4, and can be fitted into these dowel holes 6, 9. A dowel 8 having a simple protruding shape at both ends is used. The dowels 8 are formed with two-stage convex portions having substantially the same shape as the tenon 7 in the above-described embodiments at both ends. The container-containing adhesives 10 and 10 used in this case are substantially the same (symmetric) as described above with reference to FIGS. 1 to 3, and the usage (adhesion method) is also substantially the same as described above. Since it can be easily understood by those skilled in the art, the description is omitted.

Although the container-enclosed adhesive and the bonding method using the same according to one embodiment of the present invention have been described, the present invention is not limited to this specific embodiment, and the invention described in the claims The present invention can be widely modified or changed within the range.

For example, in the above-described embodiment, the large protrusion 118 is formed on the front wall 114 and the small protrusion 119 is formed on the rear wall 115 of the first cylindrical portion 111, but these protrusions are not essential and can be omitted. . The large protrusion 118 formed on the front wall 114 applies a preliminary internal pressure to the first closed space 117 that accommodates the first adhesive 12, so that the rear wall 115 is formed at the tip of the tenon 7 (or the dowel 8). The side wall 116 is easily ruptured when pressed, but since the wall thickness of the side wall 116 is thinner than the front wall 114 and the rear wall 115 as described above, such a large protrusion 118 is formed. Even if this is not the case, it is possible to preferentially rupture the side wall 116 and allow the first adhesive 12 to flow outward. Further, the small protrusion 119 formed on the rear wall 115 exerts an effect of increasing the internal pressure of the first closed space 117 and facilitating the bursting of the side wall 116 when pressed by the tip of the tenon 7 (or the dowel 8). However, since the wall thickness of the side wall 116 is thinner than the front wall 114 and the rear wall 115 as described above, the side wall 116 is preferentially ruptured even when such a small protrusion 119 is not formed. It is possible to allow the first adhesive 12 to flow outward.

Further, in the container-enclosed adhesive 10 according to the present invention, the inclined portion 113 interposed between the first cylindrical portion 111 and the second cylindrical portion 112 of the container 11 is not necessarily an essential configuration. As shown, a configuration in which the first cylindrical portion 111 and the second cylindrical portion 112 are connected by a connecting portion 125 that is substantially flush with the rear wall 115 may be employed. Even in such a configuration, the connecting portion 125 is in close contact with the step portion 63 of the mortise 6 until the mortise 7 (or dowel 8) reaches the deepest position of the mortise 6 (or dowel holes 6 and 9). Therefore, this plays the role of the separator described above and prevents the first adhesive 12 and the second adhesive 13 that have flowed out from being mixed with each other. Here, the “connecting portion” is defined as a high-level concept phrase including the inclined portion 113 in the illustrated embodiment. In the embodiment shown in FIG. 10, as described above, the front wall 114 and the rear wall 115 are shown as flat surfaces having no protrusions 118 and 119. In the embodiment of FIG. 10, the configuration other than the configuration relating to the connecting portion 125, the front wall 114, and the rear wall 115 is the same as that of the above-described embodiment. The description of is omitted.

In the above-described embodiment, the side walls 116 and 121 are preferentially ruptured when the inner pressure of the first closed space 117 and the second closed space 123 is increased by being pushed at the tip of the tenon 7 (or the dowel 8). In order to allow the one adhesive 12 and the second adhesive 13 to flow outward from the side walls 116 and 121, the wall thickness of the side wall 116 is made thinner than the front wall 114 and the rear wall 115, and the wall thickness of the side wall 121 is made smaller than the inner wall 122. Although a thinning configuration is employed, another method may be employed instead to exhibit the same effect. For example, the side wall 116 is formed of a material having a property of breaking with a pressure smaller than the material forming the front wall 114 and the rear wall 115, and the side wall 121 is formed of a material having a property of breaking with a pressure smaller than the material forming the inner wall 122. If the structure which forms and integrates these by welding etc. to make the container 11 is adopted, even if the wall thickness is the same, the side walls 116 and 121 are preferentially ruptured to form the first adhesive 12 and the second adhesive. 13 can flow out. Alternatively, the side walls 116 and 121 may be embossed or the like to provide portions that are easily broken in advance.

In the above-described embodiment, the first adhesive 12 in the first closed space 117 and the second closed space 123 when the tenon 7 (or dowel 8) is inserted into the mortise 6 (or dowel holes 6, 9). The second adhesive 13 is allowed to flow out almost simultaneously. The first closed space 117, the second closed space 123, and the tenon 7 (or the dowel 8) are changed in length in the axial direction. It is possible to freely adjust the outflow timing of the adhesive 12 and the outflow timing of the second adhesive 13. For example, by disposing the second closed space 123 from the position of the illustrated embodiment toward the first cylindrical member 111 side, the first adhesive 12 in the first closed space 117 is first allowed to flow out, and then the second closed space is discharged. The second adhesive 13 in the space 123 can be allowed to flow out.

The first adhesive 12 and the second adhesive 13 encapsulated in the first closed space 117 and the second closed space 123 are particularly limited as long as they are different types of adhesives whose original performance deteriorates when mixed. Not. Further, as described above, when the embodiment in which the outflow timing of the first adhesive 12 and the second adhesive 13 is changed is adopted, the same adhesive may be used for them.

In the above-described embodiment, it is assumed that the convex portion (tenon 7, dowel 8) and the concave portion (tenon hole or dowel hole 6, dowel hole 9) for fitting the same have a cylindrical shape. Although the outer shape or the inner shape is expressed by “diameter”, these may not necessarily be a columnar shape, and may be any shape that has a complementary shape that allows the convex portion to be fitted into the concave portion substantially densely. For example, when a two-stage prismatic convex portion is fitted into and joined to a corresponding concave portion, a container-sealed adhesive 10 having a two-stage rectangular tube-shaped container 11 corresponding thereto is used. .

The present invention can be widely implemented as an adhesive and an adhesive method used for joining these two members in a state in which the concave portion formed on one member of the two members to be joined is fitted with the convex portion formed on the other member. In particular, in fields such as wooden construction and woodwork furniture production, the applicability as a technique for fitting and joining a tenon or dowel to a mortise or dowel hole is great.
