2. Description of the Related Art Conventionally, a metal pipe called a hoso pipe has been used as a joint between a pillar receiving wood and a pillar wood.

This hoso pipe is a locking member which is inserted from the side of the pillar-supporting wood and the pillar wood into a pipe body having a predetermined length that can be installed and bridged in the joint between the pillar-supporting wood and the pillar wood. It is configured by providing a locking hole for penetrating and locking the pin, and a fitting hole into which this hoso pipe can be fitted and inserted is joined at a right angle to the upper surface of the pillar receiving wood and the upper surface of the pillar receiving wood. Pre-formed on the bottom of the pillar wood,
A communication hole that can communicate with the locking hole is formed in advance in each of the fitting holes, and a hook pipe is inserted into the fitting hole of the pillar receiving wood so that the locking hole and the communication hole communicate with each other. , The hook pin is fixed to the pillar receiving wood by inserting the locking pin into the communication through hole, and the fitting hole for the pillar wood is fitted into the upper protruding portion of the hoso pipe protruding from the upper surface of the pillar receiving wood. By connecting the locking hole of the lever upper projection and the communication hole, and fixing the pillar wood to the upper projection of this hoso pipe by inserting the locking pin into this communication through hole, the pillar wood is fixed to the pillar receiving wood. It was to be joined and fixed at a right angle.

However, in the joint structure of pillar-supporting timber and pillar-timber using such a hozo pipe, when a large-scale direct earthquake such as the Great Hanshin Earthquake occurs, the hosoe-pipe is swayed from the pillar-supporting timber by violent shaking. It was found that the pillar timber was pulled out together, and the pulled timber timber was displaced from the pillar receiving timber and dropped downward, causing the house to collapse.

Therefore, recently, as an earthquake-resistant structure for preventing this, a pillar-supporting timber and a joining part of the pillar-timber, which are jointed and fixed at right angles by the above-mentioned hozo pipe, are applied to the upper surface of the pillar-supporting timber, for example. An L-shaped reinforcing metal fitting having a contact surface and a contact surface to the side surface of the pillar wood is installed alongside and fixed with pins or nails, etc., so that the strength of preventing the pillar wood from coming off from the pillar receiving wood is enhanced. Construction using the reinforcing metal fittings is performed.

The present invention is an epoch-making product that has a high strength to prevent pillar timber from coming off and exhibits extremely excellent seismic strength without using such a reinforcing metal fitting, and that it can be easily constructed with an extremely simple structure. The present invention provides a joint between a timber receiving timber and a timber lumber.

Since the present invention is configured as described above, when the pillar-supporting timber and the pillar lumber are jointed and fixed using the product of the present invention, the locking brim portion at the bottom of the base body is located on the bottom surface of the pillar-supporting lumber. Since the bases are abutted and locked, this base body has a strong retaining strength against the direction of pulling out the pole-supporting timber upwards, so that even if a large-scale earthquake disaster occurs, the pole-supporting timber can be separated from the pole-supporting timber. It will not be pulled out easily, and it will be a joint between pillar-supporting timber and pillar timber that exhibits extremely excellent seismic strength.

In addition, the base body is simply inserted from below into the through hole formed in the pole-supporting wood in advance, and the locking flange is abutted and locked on the bottom surface of the pole-supporting wood. The base can be fixed to the pole-supporting lumber simply by driving the locking pin from one side and locking it through the locking hole. Further, the upper protrusion of the base that projects from the upper surface of the pole-supporting wood is preliminarily supported by the pillar lumber. The pillar wood is fixed to the upper protrusion by simply locking the locking pin that is driven into the pillar wood from the side and inserted into the locking hole of the upper protrusion. Since it is possible to join and fix the pillar wood at right angles to the pillar receiving wood, it will be possible to perform the construction work very easily, and on top of that, while forming the locking brim portion at the bottom of the tubular pipe, This pipe is very simple to construct because it has only locking holes. For the processing of timber to be used, it is enough to change only by penetrating the fitting hole of the pillar receiving wood for the hoso pipe described in the conventional example. It becomes a tool.

According to the second aspect of the invention, since the penetrating directions of the locking pins that penetrate the locking holes intersect with each other, the pillar-supporting wood and the pillar wood are satisfactorily locked against rotation of the base. The strength of the pillar timber will be further improved, and when a large force is applied to the pillar receiving wood in the pull-out direction of the pillar lumber, the pillar timber will not easily crack. It is a joint between the timber receiving timber and the timber.

Further, in the invention according to claim 3, since the locking brim portion is less likely to interfere with the bottom portion of the pillar receiving wood, it does not hinder the frame construction method, and the base for placing the bottom surface on the foundation is installed. It is an excellent joint between wood for pillar support and pillar wood that can be used in good correspondence with pillars.
