Description

  The present invention relates to a joint fitting, and in particular, is fixed to a side face of a cross member such as a beam and having a longitudinal slit portion, and is fixed to a front end of a cross member such as a joist and engages with the slit portion. The present invention relates to a joint metal fitting comprising a second metal fitting and capable of safely, easily and firmly joining the end face of the crosspiece member to the side face of the crosspiece member.

Conventionally, when joining wooden members, such as a beam and joists, metal joining metal fittings have been used.
In general, when using joint metal fittings, it is possible to efficiently attach the joint metal fittings to the wooden parts in the factory instead of carrying out complicated joint processing on the wooden parts. Members can be joined together. Furthermore, wood members can be firmly joined together by using a joining metal fitting.
Thus, the joining metal fittings have excellent effects, and various structures have been proposed and put into practical use for the purpose of further enhancing these effects.

For example, in the joint structure of Patent Document 1, a wedge guide piece is inserted into a wedge insertion hole and a wedge window hole corresponding to each other, and a driven elongated wedge is driven and inserted, whereby the joint end surfaces are pressed and tightened. In a wooden building, wood can be joined with a simple structure with sufficient shear strength and tightening strength, and in good shape.
JP-A-7-279260 (Claim 3, FIG. 2)

  However, the joining structure according to Patent Document 1 is for joining long end faces that are relatively light, and joining the end face of the cross member to the side face of the cross member like joining a beam and joists. This is not taken into consideration. That is, since the wooden members are joined by only one rod-shaped metal fitting, there is a problem in strength in joining the beams and joists. In addition, when joining a heavy wooden member, for example, a joist, to a beam at a construction site, it is first necessary to temporarily and safely temporarily join the joist to the beam, and then tighten it. Then, this request cannot be met.

  The present invention has been considered in view of the above circumstances, and can be safely and easily temporarily joined to the side surface of the cross member at the construction site, and after the temporary joint, It is an object of the present invention to provide a joint fitting that can be firmly joined so that the surface does not come out upward.

In order to achieve this object, the joint metal fitting of the present invention is a joint metal fitting for joining wood members by combining a first metal fitting attached to one wooden member and a second metal fitting attached to the other wooden member. The first metal fitting has first and second surfaces offset in the thickness direction, of which the first surface is fixed to the one wooden member and the second surface is engaged with the second metal fitting. It has a configuration having a vertical slit portion.
If it does in this way, a 2nd metal fitting can be easily engaged using a slit part and the other wooden member can be easily temporarily joined to one wooden member. In addition, by reducing the amount of offset, the width of the joist bracket from one wooden member can be reduced, so when transporting the wooden member to which the joist bracket is attached to the construction site with a truck, Loading efficiency can be improved.

Further, in the joining metal fitting of the present invention, the second metal fitting has a rod shape, and a pin inserted from a wall portion of the other wooden member when the second wooden member is engaged with the other wooden member on the other wooden member side. A structure having a pin hole that penetrates, and a groove in a direction orthogonal to the pin hole is formed at a position opposed to the peripheral surface on the one wooden member side, and this groove is engaged with the slit portion of the first metal fitting It is as.
If it does in this way, since a rod-shaped member can be used as a 2nd metal fitting and a structure can be simplified, the cost reduction of manufacturing cost can be aimed at. In addition, as the mounting process to the other wood member, it is only necessary to drill a pin penetration hole and an insertion hole for inserting the second metal fitting, so that workability can be improved.

Further, in the joining metal fitting of the present invention, the second metal fitting is a plate shape having a thickness narrower than the width of the slit portion of the first metal fitting, and the other wooden member side and the other wooden member side, A pin that has a pin hole through which a pin inserted from the wall of the other wooden member penetrates when the second metal fitting is inserted into the one wooden member side. It is set as the structure engaged with the said slit part so that it may be located between the 2nd surface of said 1st metal fitting, and said one wooden member.
If it does in this way, since a plate-shaped member can be used as a 2nd metal fitting and a structure can be simplified, the cost reduction of a manufacturing cost can be aimed at.

In the joining metal fitting of the present invention, the first metal fitting has a third surface connecting the upper portion of the first surface and the lower portion of the second surface, and is located below the third surface. The third metal fitting inserted from the wall of the other wooden member is further configured.
If it does in this way, it can prevent effectively that the 2nd metal fitting pulls out upwards, and can improve joint strength.

Moreover, the joining metal fitting of this invention is set as the structure which attaches said 1st metal fitting to the beam as one wooden member, attaches said 2nd metal fitting to the joist as another wooden member, and joins the said beam and joist.
In this way, the joist can be temporarily joined to the beam by dropping the joist from above, so that the beam and the joist can be joined efficiently.

  As described above, the joining bracket according to the present invention is fixed to the side surface of a cross member such as a beam and having a longitudinal slit portion, and to the slit portion fixed to the top end of a cross member such as a joist. It is composed of a second fitting to be joined, and the front end of the cross member can be temporarily and safely temporarily joined to the side face of the cross member. Can be firmly joined so that they do not fall upward.
