At the joints of these members, various kinds of hardware, such as short metal hardware and box metal hardware, are widely used in recent years to secure earthquake resistance against shaking such as an earthquake, from a traditional method of processing and combining wood.

Further, in order to further improve the earthquake resistance, a composite member having a reinforcing material having a higher elastic modulus than conventional wood, such as steel, is used for the purpose of improving the mechanical strength of the structural member in the frame construction method. Use has also been proposed. That is,
As shown in FIG. 8, in a wooden structure of the framed construction method, the steel material 71 is used as a beam material that greatly affects the strength, stability, and durability of the structure.
The construction of a building by combining this steel frame material 71 with wood materials 72, 72 has been studied. As shown in detail in FIG. 9, use of a composite beam material 7 in which a steel frame material 71 and wooden materials 72, 72 are combined is proposed as a beam material as a horizontal member. The composite beam member 7 is constructed by binding the wooden members 72, 72 and other members such as pillars and braids using various flat plate-shaped joint fittings A such as an H-shaped fixture.

In recent years, wooden houses with a three-story structure have become widespread in urban areas in order to improve the living environment. This three-story wooden house has a larger weight per unit area than a general two-story house, and a larger compressive load is applied to the columns.

Therefore, in order to increase the safety factor in terms of strength against the compressive load on the column, in a three-story wooden house, a larger compressive load is applied partially together with the composite beam 7. A wooden pillar having a large cross-sectional area may be used as a pillar at a place where it is assumed that the above-mentioned situation occurs. That is, in a wooden house of two stories or less, a pillar having a side length of 105 mm is generally used. In a wooden house of three stories, for example, a pillar having a side length of 120 mm is used. May be used.

On the other hand, it is conceivable as a countermeasure to bend the joint fitting A according to the step between the column 6 and the horizontal member in advance, but in this case, the size of the step between the column 6 and the horizontal member is considered. It is necessary to prepare a joint fitting formed corresponding to the above, and it is assumed that a plurality of types of joint fittings are required. Therefore, it was assumed that preparations would be troublesome.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a method in which, when there is a step having a different size between a column and a horizontal member, the end of the column is set to the size of the step.
