Device for forming framework of wooden building

DETAILED DESCRIPTION In view of the foregoing, an object of the present invention is to provide an improved device for forming a framework composed of a vertical post and a transverse lumber, which does not require a substantial cut on the vertical post.
The present invention will be described hereinafter.
A device for forming a framework of a wooden building according to the present invention comprises a steel pipe, screw bar, joint, bolt and joint stick.
The steel pipe is tightly inserted in a hole having a bottom wall formed at the top and bottom edges of a vertical post along its center line.
The screw bar is such that its upper half portion is screwed into a screw hole formed at the mouth portion of a steel pipe inserted into the bottom edge of a vertical post, while its lower half is screwed into a screw hole formed at the mouth portion of a steel pipe inserted into the top edge of a vertical post positioned underneath the aforementioned vertical post.
The screw bar connects the steel pipes and thus the vertical posts in series.
The joint comprises a belt-shape base portion which is located along the vertical post in the vertical direction, and a flange portion which is oriented at a right angle from the base portion.
The bolt passes through a hole of the base portion of the joint and a hole of the vertical post, and the bolt is screwed into a screw hole of the steel pipe, securing the joint to the vertical post.
The screw hole of the steel pipe is formed along the radial direction of the steel pipe.
The joint stick is inserted into holes of the transverse lumber and the flange portion, joining the transverse lumber with the flange portion of the joint.
The joint is inserted in the slit formed at the edge portion of the transverse lumber.
According to the present invention, there is provided an improved device for forming a framework composed of a vertical post and a transverse lumber, which does not require a substantial cut on the vertical post.
Further, it is possible to improve the yield in forming a framework of a wooden building since vertical posts and transverse lumbers can be prepared in a factory and easily formed at each construction field or site
