Description

  The present invention relates to a guide member for joining wood members and a joining structure using the guide tool.

  For example, in the joint structure between a base and a pillar in a wooden framed house, the traditional tenon and mortise joints are used. In other words, mortise holes are engraved in advance at the mounting position of the pillar on the base, and mortise processing is applied to the base joint side of the pillar, and the tenons are inserted into the mortise so that the pillar is inserted onto the base. It is fixed. In addition to this, at present, seismic reinforcement is carried out by attaching a thin metal strip or other external auxiliary hardware to the outer surface of the joint part.

  However, if the wood that makes up the pillar is made of soft wood, the tenon will easily buckle when a lateral shearing force acts between the pillar and the base due to an earthquake, etc. Even if they are interposed by external attachment, the joints between the pillars and the auxiliary hardware are easily destroyed.

  As countermeasures, the column material may be made of a high-strength material, or the member cross section may be made large.

  Therefore, the present applicant has previously developed a joint structure shown in the following patent document. In this example, taking a joint structure between a base and a column as an example, as shown in FIG. 1 of the same document, a concave groove is formed in a portion corresponding to a tenon portion of the column, and a pair of reinforcing steel plates is provided for this. The wood pieces sandwiched between the two are fitted in a state of projecting from the end of the pillar, and this projecting portion is used as a tenon, or as shown in FIG. A slit is formed, and the thin steel plate is inserted into the slit to reinforce both sides of the tenon, and a plurality of fixtures such as nails or tapping screws are driven into the side of the column to fix the thin steel plate to the column.

In this structure, the rigidity of the tenon is secured by the reinforcing effect of the thin steel plates fixed on both sides of the tenon in a fixed state, and the buckling strength can be increased, and at the same time, a plurality of fixing tools penetrate the tenon. Because it is attached, the base-column joint strength is higher than in the conventional case where auxiliary metal fittings are externally attached, the seismic strength is increased, and the appearance is simple.
