Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for joining wooden members, and more particularly to a method for joining wooden members used in various parts of a building (all parts regardless of whether they are structural materials or non-structural materials).

[0002]

2. Description of the Related Art In a conventional method for joining members in a wooden structure, a concavo-convex process (such as mortise process) is applied to each joint end of a pair of wooden members to be joined, and the concavo-convex processed part of one wooden member and the other wooden member The pair of wooden members are joined by engaging and fastening the concave and convex portions of the members.

According to another conventional member joining method, a joining metal piece and each wooden member which are abutted over both of a pair of wooden members to be joined (straddling a so-called pair of wooden members). The pair of wooden members are joined by screwing with a through bolt or the like.

[0004]

In the conventional joining method in which the joining ends of the pair of wooden members to be joined are provided with the concavo-convex processing, precise concavo-convex processing is required in order to secure the desired joining performance. As a result, a high processing technique is required, which in turn causes an increase in processing cost and processing time, which is inconvenient in terms of processability or processing technique.

On the other hand, in the conventional joining method of joining a pair of wooden members through a joining metal and a through bolt, the pair of joined wooden members structurally exerts a joining strength as a pin joint. This is a limit, and there is an inconvenience in terms of joint strength in that a substantial rigid joint cannot be realized.

Further, in the conventional joining method of joining a pair of wooden members through the joining metal and the through bolt, the joining metal is finally exposed to the outside, so metal corrosion peculiar to the joining metal is likely to occur. . As a result, for example, there is a disadvantage that durability against salt damage, that is, weather resistance is poor.

The present invention has been made in view of the above-mentioned problems, and it is possible to realize a substantially rigid joint with a simple processing technique and to realize sufficient joint strength and weather resistance. An object of the present invention is to provide a method of joining wooden members that can be performed.

[0008]

In order to solve the above problems, according to the present invention, a groove extending in a predetermined direction is formed in each of a pair of wooden members and formed in each of the pair of wooden members. By embedding a rod-shaped member so as to extend over both of the pair of wooden members in the groove formed, by filling an adhesive in the groove in which the rod-shaped member is embedded, A method for joining wooden members, characterized in that the pair of wooden members are joined together through the above.

According to a preferred aspect of the present invention, after filling the groove in which the rod-shaped member is embedded with an adhesive,
The groove is covered with a predetermined plug member. Moreover, it is preferable that a plurality of sets of grooves for embedding the rod-shaped member are formed, and one bar-shaped member is embedded in each groove of the plurality of sets of grooves. Furthermore, it is preferable that the pair of wooden members be joined via a wooden member other than the pair of wooden members.

According to a specific aspect of the present invention, the pair of wooden members extend along a predetermined axis, and the groove is generally U-shaped from one end thereof along the longitudinal axis of each wooden member. The rod-shaped member is formed so as to extend for a predetermined distance with a cross section of, and is positioned such that the one ends of the pair of wooden members face each other, and then extends into both of the pair of wooden members. As a burial bar. In this case, it is preferable that the reinforcing bar is a deformed reinforcing bar. Further, before the adhesive is filled into the groove in which the reinforcing bar is embedded, a predetermined seal is formed at the abutting portion of the pair of wooden members in order to prevent leakage of the adhesive to be filled. Preferably.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, a groove extending in a predetermined direction is formed in each of a pair of wooden members to be joined. When the pair of wooden members are linear members extending along a predetermined axis line, such as beam members, a U-shaped member is generally formed from one end (joint end) along the longitudinal axis of each wooden beam member. A groove is formed in a straight line so as to extend a predetermined distance in cross section.

Then, a rod-shaped member is embedded in the groove formed in each of the pair of wooden members so as to extend over both of the pair of wooden members. For example, when joining a pair of beam members along the longitudinal axis direction thereof, after positioning the pair of beam members so that their one ends (joining ends) face each other, the beam members are spread over both of the pair of beam members. As a bar-shaped member, a bar steel such as a deformed bar is embedded in the extended groove. In this case, grooves for burying the deformed reinforcing bars are formed at two positions, for example, one surface side of the beam member and the opposite surface side of the other, and each groove has one deformed shape slightly shorter than the groove length. Reinforcing bars are buried respectively.

Finally, a pair of wooden members are joined through the deformed reinforcing bars by filling a predetermined adhesive in the groove in which the deformed reinforcing bars as the rod-shaped members are embedded and curing the adhesive. In this case, before the adhesive is filled into the groove in which the reinforcing bars are embedded, a predetermined seal is formed at the abutting portion of the pair of wooden members, thereby preventing the adhesive to be filled from leaking. it can. In addition, after filling the adhesive in the groove in which a rod-shaped member such as a reinforcing bar is embedded, by covering the groove with a predetermined plug member, a good appearance of the joint can be maintained and a joint such as a reinforcing bar can be formed. The hardware can be more completely isolated from the external environment.

As described above, in the joining method of the present invention, the groove extending in the predetermined direction is only formed with a not so high accuracy, and it is not necessary to perform the fine uneven processing unlike the prior art. In particular, when a pair of beam members are directly joined along the longitudinal axis direction, the joining end face of each beam member is simply formed in a flat shape as a butt face, which is different from the prior art. Does not require advanced processing technology. Also,
Even when a pair of beam members are indirectly joined along the longitudinal axis direction through another member such as a wooden pillar member, the joint end surface of each beam member is formed into a flat shape as a butt surface. However, it does not require an advanced processing technique unlike the conventional technique.

Further, in the joining method of the present invention, the force acting on one of the wooden members is transmitted to a rod-shaped member such as a reinforcing bar adhered to the one wooden member, and the force transmitted to the reinforcing bar is then transmitted to the reinforcing bar. Is transmitted to the other wooden member glued to. In other words, the stress transfer at the joint according to the invention is
This is done through a bar-like member, such as a reinforcing bar, which is firmly bonded and embedded over both of the pair of wooden members. as a result,
It is possible to secure a large stress transmission strength of the joint, that is, the joint strength, through the reinforcing bar having high strength. Further, for example, by embedding one deformed reinforcing bar in each groove formed at two positions, one surface side of the beam member and the other facing surface side of the other, it is possible to realize a substantially rigid joint. it can.

Further, in the joining method of the present invention, the reinforcing bar, which is the joining metal object, is covered with at least the adhesive, and when the stopper member is used, it is also covered with the stopper member. That is, since the reinforcing steel, which is a metal joint, is not exposed to the outside, it is substantially isolated from the external environment, and it is possible to effectively avoid metal corrosion and ensure sufficient weather resistance. . As described above, according to the present invention, it is possible to realize a substantially rigid joint and a sufficient joint strength and weather resistance with a simple processing technique.

Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view for explaining a method of joining wooden members according to an embodiment of the present invention, and shows a pair of wooden members to be joined and a deformed bar as a rod-shaped member. Further, FIG. 2 shows (a) a step of burying deformed bar, (b)
It is a figure which shows the filling process of an adhesive agent, and the process of (c) covering a groove | channel with a plug member. Further, FIG. 3 is a perspective view showing the appearance immediately before the groove is covered with the plug member. In the present embodiment, the present invention is applied to the direct joining of the pair of wooden beam members along the longitudinal axis direction.

In FIG. 1, a pair of wooden beam members 1 and 2 to be joined are formed with a groove having a generally U-shaped cross section along the longitudinal axis thereof. That is, the groove 1a is formed on the upper surface of the beam member 1 on the left side of the drawing so as to extend a predetermined distance from the joining end thereof. Further, a groove 1b (not shown in FIG. 1) is formed on the lower surface of the beam member 1 in the figure so as to extend from the joint end thereof by a predetermined distance. Similarly, a groove 2a is formed on the upper surface of the beam member 2 in the drawing, and a groove 2b is formed on the lower surface of the beam member 2 in the drawing.

In this embodiment, after the joint end surface 1c of the beam member 1 and the joint end surface 2c of the beam member 2 are positioned so as to abut against each other, the deformed rebar 3 as a rod-shaped member is embedded.
That is, the deformed bar 3 is embedded so as to extend over the pair of beam members 1 and 2 in the grooves (1a and 2a) formed in the pair of beam members 1 and 2 (FIG. 2).
(See (a)). Here, the length of the deformed bar 3 is equal to that of the groove 1a.
Needless to say, the length is set to be slightly shorter than the sum of the length and the length of the groove 2a. Similarly, another deformed bar is embedded in another groove (1b and 2b) formed in the pair of beam members 1 and 2, but in order to avoid redundant description, the beam members 1 and 2 will be described below. The description of the present embodiment will be advanced by focusing only on the joining via the deformed reinforcing bar 3 on the upper side of.

Next, a predetermined adhesive 5 is filled into the grooves (1a and 2a) in which the deformed reinforcing bars 3 are embedded by using an appropriate filling device 4 (see FIG. 2 (b)). In this case, by forming a predetermined seal 7 (see FIG. 3) at the abutting portion of the pair of beam members 1 and 2 before filling the adhesive 5 into the groove in which the deformed reinforcing bar 3 is embedded, It is possible to prevent the adhesive 5 to be filled from leaking from the butted portion.

Finally, in order to keep the appearance of the joint good,
In order to more completely isolate the deformed reinforcing bar 3 from the external environment, the groove is buried with the deformed reinforcing bar 3 after being filled with the adhesive 5, and then the groove is covered with a predetermined plug member 6. Thus, the two formed on the pair of wooden beam members (1 and 2)
A pair of wooden beam members are substantially connected via two sets of deformed reinforcing bars (3 and reinforcing bars not shown) that are adhesively embedded in the grooves of the set (the group consisting of 1a and 2a and the group consisting of 1b and 2b). Rigidly joined to.

As described above, in the present embodiment, it is necessary to perform the fine uneven processing as in the prior art only by forming the linear groove having the U-shaped cross section with a not so high accuracy. Absent. Further, the joint end surface of each beam member is only formed as a flat surface as a butt surface, and does not require a high-level processing technique as in the conventional technique. Further, in the present embodiment, it is possible to secure a large joint strength via the deformed rebar having a large strength that is firmly bonded and embedded over both the pair of beam members. Further, by embedding one deformed bar in each groove formed at two positions, one surface side of the beam member and the opposite surface side of the other, a substantially rigid joint can be realized. .

Further, in this embodiment, since the deformed rebar which is a metal joint is covered with the adhesive and the plug member, the rebar is not exposed to the outside and is substantially isolated from the external environment. As a result, it is possible to effectively avoid metal corrosion and ensure sufficient weather resistance. As described above, in the joining method of the present embodiment, the simple processing technique
Substantially rigid bonding can be realized, and sufficient bonding strength and weather resistance can be realized.

In the above-mentioned embodiment, the present invention is applied to the direct joining of the pair of wooden beam members along the longitudinal axis direction. The present invention can be applied to a method for joining wooden members used for all parts regardless of materials. Further, in the above-mentioned embodiment, although the deformed bar is used as the bar-shaped member, a bar-shaped member made of general bar steel including a round steel bar and other suitable materials can be used.

Further, in the above-mentioned embodiment, the example of direct joining along the longitudinal axis direction of the beam member is shown, but the beam member is indirectly joined through another member such as a wooden column member. The present invention can also be applied to. In addition, in the above-described embodiment, by covering the groove with the plug member, the external appearance of the joint is maintained good and the deformed bar is more completely isolated from the external environment. However, the use of the plug member is not essential in the present invention, and it is possible to isolate the deformed reinforcing bar from the external environment to some extent by covering the deformed reinforcing bar and thus the groove with an adhesive.
