| Summary: | Up to this time, wooden materials have been used for producing columns and beams and braces. These wooden components are framed together to form a building skeleton. However, in order to improve the strength, stability, and durability of the components, use of steel materials has also been considered. Applicant of this application proposed a composite beam which is formed of a steel material and a wooden material (Japanese patent laid open TOKUKAIHEI 8-13690). This composite beam is illustrated by the perspective views shown in
and
. As shown in these figures, this composite beam is formed of a steel beam (
) and a wooden member (
). The cross section of the steel beam is I-shaped. Namely, a pair of flat plate members (
) are lined in parallel and are connected each other by a perpendicular plate member (
) at the central position of the flat plate members (
). On the outer surfaces of the flat plate members (
), wooden members (
) are attached. Under this configuration, the strength, stability, and durability of the component is increased due to the use of the steel beam member (
), and the application of conventional wood-working processing to the beam becomes possible due to the attachment of the wooden members (
).
A joint structure for joining a composite beam and a column is disclosed. The composite beam includes an I-beam and a pair of wooden members. The joint structure includes a mortise pin provided on the composite beam and protruding beyond an outer surface of one of the wooden members. The mortise pin is provided with a through-hole at a predetermined position. A bottom hole is provided at a bottom surface of the column in a manner that the bottom hole is adapted to receive the mortise pin. A horizontal hole is provided at a side face of the column at a position corresponding to the through-hole of the mortise pin. The composite beam is connected with the column by first inserting the mortise pin into the bottom hole of the column and then inserting a locking pin into the through-hole of the mortise pin and the horizontal hole of the column such that joint of the composite beam and the column is firmly secured. A method of joining a composite beam and a column is also disclosed. |
