Description

  The present invention relates to a metal joint processed and formed so as to have a substantially U-shaped cross-sectional shape, which is used in a beam winning joint in which a lateral beam member and an additional beam member are joined to an end of a beam winning beam member. The present invention relates to a mounting structure and a joint hardware.

  For example, in a wooden building such as a wooden house building, the joint between the column member and the beam member constituting the frame structure of the building is passed as a single piece without dividing the column member, and the joint metal fitting is attached to the side of the joint. In general, it is a column winning joint with a structure in which beam members are joined via, for example, a cantilever balcony or a column member and a beam member for forming an overhang portion in recent years. As a joint structure, a beam-winning joint is adopted in which the column member is divided at the top and bottom of the beam member, and the column member is erected vertically from the upper surface and / or lower surface of the end of the beam member. (For example, refer to Patent Document 1 and Patent Document 2).

  In such a joint structure at the beam-winning joint, as the other beam member on the side surface or end surface of the beam-winning beam member, for example, a lateral beam member extending perpendicularly from the side surface of the beam-winning beam member or a beam-winning beam In some cases, additional beam members extending linearly from the end face of the member are joined. For these lateral beam members and extension beam members, for example, plate-shaped joint hardware having a substantially U-shaped cross-sectional shape is attached to the side face or end face of the beam-winning beam member using a bolt member. By fitting a joining groove formed on the end face of the lateral beam member or the additional beam member into the projecting plate portion of the steel plate and fixing it using a drift pin, it is joined to the beam winning beam member. ing.

  On the other hand, in recent years, as a beam member for obtaining a large proof stress or a beam member used as a representative beam, for example, a beam member having a large beam length (beam height) having a beam height of about 270 to 900 mm is preferably used. There is. Further, when joining such a beam member with a large beam to the beam-winning beam member, there is a possibility that sufficient joining strength cannot be obtained only by using a conventional metal fitting having a substantially U-shaped cross-sectional shape. is there. For this reason, it has been considered to improve the bonding strength by using bonding hardware in two stages (a plurality of stages) in the vertical direction (see, for example, Patent Document 3).
