[Technical field to which the invention belongs]

 TECHNICAL FIELD The present invention relates to a connecting metal fitting for a building for connecting columns divided vertically.

[0002]

[Prior art]

 Conventionally, pillars are important parts for supporting beams and the like in the frame structure of a wooden building. In recent years, even in the frame structure, a three-story wooden building has been generalized. Long pillars are used for supporting objects such as beams. However, the long pillars are inconvenient when transporting to the construction site, and are inconvenient. For this reason, the pillars used for three-story wooden buildings are divided into a plurality of columns and transported to the construction site, where they are connected to form long columns.

[0003] As a connection fitting for connecting a plurality of columns to each other, for example, a connection fitting 50 shown in FIG. 5 is known. The connection fitting 50 is formed in a cylindrical shape as a whole, and has a pair of upper and lower holes 52 through which bolts 51 are passed. Then, fitting holes 54 for inserting the connection fittings 50 are vertically provided on the joint end surfaces of the divided upper and lower columns 53 and 53A so as to face each other. A corresponding through hole 55 is formed. Then, the connecting metal fittings 50 are inserted into the fitting holes 54 of the columns 53 and 53A to connect the respective columns 53 and 53A, and the upper and lower bolts 51 inserted into the through holes 55 of the pillars 53 and the holes 52 of the connecting metal fittings 50 are used. The columns 53 and 53A are fixed.

[0004] Such a conventional connecting fitting 50 has a simple structure in which the cylindrical connecting fitting 50 is simply inserted into the fitting holes 54 of the upper and lower columns 53 and 53A and fixed with the bolts 51. It is easily bent due to the shear stress applied at the time, and as described above, there is a problem that when a column of a three-story wooden house is fixed, the earthquake resistance is poor. Further, in the case where a beam or the like is fixed at the connecting portion of the columns 53 and 53A using a steel joint, a bolt for fixing the joint is vertically provided at the center of each of the columns 53 and 53A. It hits the connection fitting 50. For this reason, it is not possible to attach a joint fitting for fixing a beam or the like to a joint portion between the upper and lower columns 53 and 53A, and there is a problem that the fixing position of the beam is also restricted by the position of the connection fitting 50.

The present invention is intended to solve such a problem, and has as its first object to provide an architectural connection fitting excellent in earthquake resistance. It is a second object of the present invention to provide an architectural connection fitting capable of fixing a beam to a connection portion.
