Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint structure of a column and a body difference (or a beam such as a floor beam) in a wooden frame, and a joint metal piece therefor.

[0002]

2. Description of the Related Art A conventional wooden construction method for connecting columns and body differences is shown in FIG.
As described above, the tilting short tenon and the metal strip with the specially shaped joint are used. For floor beams,
Partly insert the long tenon and secure it with a battledore bolt. Generally, carpenters work on-site to process these joints, but recently, pre-cut processing has been performed at the factory in advance using a dedicated machine called a router. . This pre-cut is characterized in that the joint portion is rounded as shown in FIG. 8 due to the nature of the machine.

[0003]

By the way, when a shearing force is transmitted from the barrel difference to the column, the column acts with a force in the fiber direction of the wood, and the beam exerts a force in a direction orthogonal to the fiber direction. . In this case, since the wood has a strong property in the fiber direction but a weak property in the orthogonal direction, it is necessary to increase the cross-sectional area of the tenon of the barrel difference to secure the supporting force of the shearing force. For this reason, the mortise of the column is inevitably made large, and the cross-section loss becomes large, so that the strength on the column side decreases.

In addition, the processing of the joint requires skill and requires a specialized carpenter, and in the case of precutting, a dedicated processing machine is required.

Further, when the strip metal object is used as described above,
Not only does it hinder the storage of floors, ceilings, bearing walls, etc.,
In the case of a building having a structure in which the joint portion is exposed, there is a drawback that the strip metal objects and nails are visible and the appearance is impaired.

The present invention eliminates the above-mentioned conventional drawbacks, eliminates the need for complicated processing of the joint portion of the column and the body difference, can bear a large shearing force, and is excellent in appearance. It is intended to provide a joint structure and its hardware.

[0007]

In order to solve the above problems, the present invention is directed to a pin member in which a connecting portion of a metal joint is inserted into an upper end surface of a column and the column side surface is inserted through the connecting portion. While the connecting part and the pillar are integrally joined with each other, a vertical joining plate protruding laterally from the connecting part is inserted into the slit of the barrel difference end face, and this plate is penetrated from the side face of the barrel difference. It is characterized in that the joint plate and the body difference are integrally joined by the inserted pin member.

In the above, the joining plate usually projects outwardly between the end faces of a pair of vertically opposed columns, and the barrel end portion into which the joining plate is inserted is also inserted between the end faces of the columns. .

At this time, the left and right corners of the tip of the barrel difference are cut off at 45 degrees and inserted into the column end faces without interference between the barrel differences in the directions orthogonal to each other, but the barrel difference is inserted. It is conceivable to attach a cover to the empty space to close this part.

Similarly, in order to solve the above-mentioned problems, a joining metal article of the present invention is provided with a connecting portion which is inserted between end surfaces of upper and lower columns facing each other, and an end portion of a body difference protruding from the connecting portion. The connecting plate has an insertion hole through which the pin member inserted from the side of the column penetrates, and the connecting plate has an insertion hole through which the pin member inserted from the side of the barrel is inserted. It is characterized in that holes are formed.

Further, in the joining structure and the metal fitting of the present invention as described above, a rod-shaped material such as round steel is usually used as the connecting portion. On the other hand, a part of the insertion hole of the pin member formed in the joining plate is composed of a slit or a notch formed in the upper end of the joining plate, and the pin member is first attached to the body gap to make these slits. Alternatively, it may be possible to temporarily install and position the body difference by inserting the notch portion from above.

In the present invention, the barrel difference is meant to include various horizontal members in the wooden frame, such as beams and floor beams.

[0013]

The connecting portion made of the round steel or the like is fixed to the pillar by inserting it into the upper end surface of the pillar and releasing the pin member penetrating them. On the other hand, the body difference is joined via a pin member to the joining plate inserted into the slit of the end face,
From this pin member, the shearing force from the barrel difference is transmitted to the column via the joint plate and the connecting portion, and directly from the barrel difference lower end face to the upper end face of the column.

According to the present invention, since the end faces of the pin and the joint plate are only exposed to the outside of the column and the barrel difference, the appearance is good. Further, the processing of the joint on the pillar side may be performed by forming a hole into which the round steel and the pin are inserted, and the joint on the barrel side may be formed by forming the slit into which the joining plate is inserted and the hole into which the pin is inserted. It does not require a professional craftsman, it can be easily processed in the factory, and there is no large cross-section loss in the pillar and body difference.
