In recent years, as a countermeasure against disasters such as earthquakes and typhoons, it has been particularly important to improve the strength of the frame construction method of wooden buildings such as wooden houses (for example, November 1995). Chapter III in “Wood Industry VOL.50, No.11” issued by the Japan Wood Processing Technology Association and April 1996
From this viewpoint, reviewing the conventional joint structure from this viewpoint reveals that the wood fibers extend in the longitudinal direction on the side surfaces of the ordinary wooden pillar 1. The rigidity and strength are exhibited depending on the resistance at the time when the opening of the horizontal member is inserted into the wood fiber on the side surface of the wooden pillar 1 in the direction perpendicular to the wooden material, so that the strength and rigidity against the penetration of the horizontal member are reduced. Because of its extremely small size, in the conventional joining structure as described above, at the beginning of the joining, the side surface of the wooden pillar 1 sufficiently supports the end surface and the side surface of the end of the wooden cross member 2 abutting on it. When a large horizontal force is applied due to an earthquake, a typhoon, or the like, a compressive deformation occurs on the side surface of the wooden pillar 1, and the end surface and the side surface of the wooden cross member 2 dig into the side surface of the wooden pillar 1, and the joints are compared. Very low rigid joint strength (G) Only the transmission performance and bending rigidity can be exhibited, and the compression of the side surface of the wooden pillar 1 occurs gradually with the lapse of time, and the end surface and the side surface of the wooden lateral member 2 It has been found that there is a problem that the tension bolt 5 and the bolt 6 with a flange are loosened in the side surface and the bending moment transmitting performance and the bending rigidity of the joint are reduced.

[0006] Conventionally, Japanese Utility Model Publication No. 7-28268 discloses a plywood that is fitted and bonded to both sides of an end portion of a structural lumber for the purpose of solving the problem of the edge of the structural lumber squeezing into the side surface. A technology has been disclosed in which the compressive strength of the lower surface, which is the side surface on the side where the end surface of the plywood at the end is visible, is strengthened by the compressive strength in the fiber direction of the plywood, but such technology can also be applied to wooden pillars. It is not enough to reinforce the side surface of the wooden pillar, and therefore, conventionally, with a low-cost and simple joining structure, maintaining a sufficiently high joint strength of the rigid frame for a long time, continuing high bending moment transmission performance and high bending rigidity It has been difficult to obtain a joint that results in a static.

[0007]

SUMMARY OF THE INVENTION The present invention provides a joint structure which advantageously solves the above-mentioned problems, and provides a joining structure between a wooden pillar of the present invention and a lateral wooden member. In the joint structure, at least a portion of the wooden pillar in the longitudinal direction is formed by a wood compression-molded aggregate, and the end of the wooden cross member on the side of the wooden compression-molded aggregate is abutted by bolt tension. The wooden pillar and the wooden horizontal member are joined together.

[0008] According to the joint structure of the present invention, the compressive strength of the side surface is substantially equivalent to that of ordinary wood such as solid wood for wood pillars (wood as it is made from raw wood) and laminated wood. On that side of the timber compression molded aggregate that is expensive,
Since the ends of the lateral wooden members are in contact with each other, their side surfaces do not undergo compressive deformation even under a long-term compressive force. The fact that the side of the timber column continues to support the end of the timber abutment abutting against it, so that the tension of the bolt is loosened by the indentation of the end of the timber into the side of the timber column. Since there is no joint, it is possible to obtain a joint that continuously maintains high bending moment transmission performance and high bending rigidity while maintaining a sufficiently high rigid frame joint strength for a long period of time. Are joined by the tension of the bolt, so that the joining structure can be made inexpensive and simple.

In the present invention, the bolt may be a tension bolt, and the joining structure may constitute a tension bolt type joint or a joint beam type joint, and the bolt may be a flanged bolt. The joining structure may constitute a flange joining type joint.

In the present invention, the whole of the wooden pillar in the longitudinal direction may be formed of a wood compression-molded aggregate, but a part of the wooden pillar in the longitudinal direction may be formed of a wooden compression-molded aggregate. In such a case, the ends of the wood compression-molded aggregate and ordinary wood such as solid wood and laminated wood are joined together to form the wood pillar. If a part of the wooden pillar in the longitudinal direction is formed of the wood compression-molded aggregate, the manufacturing cost can be reduced as compared with the case where the whole is formed of the wood compression-molded aggregate.

However, the joint structure for joining the ends of the wood compression-molded aggregate with ordinary wood such as solid wood and glued laminated wood may be a finger joint. In this case, corrosion problems may occur. And high joining strength can be obtained at low cost. Further, the joining structure for joining the above-mentioned ends may be a structure in which a metal square pipe inserted into the inside of the ends is connected to those ends by a transverse member. High joining strength can be obtained without causing much problem, and even in processing at a construction site.

Further, the present invention is also directed to a wooden column having a part in the longitudinal direction formed by a wood compression-molded aggregate. If this wooden column is used in the joint structure of the present invention, the above-described various effects can be obtained. Can be played.
