Abstract: A device for forming a framework of a wooden building including a steel pipe, screw bar, joint, bolt and joint stick. The steel pipe is tightly inserted in a hole formed at the top edge and/or the bottom edge of a vertical post. The screw bar connects two vertical posts in series as an upper half thereof is screwed into a screw hole of a steel pipe inserted into the bottom edge of a vertical post, while a lower half thereof is screwed into a screw hole of a steel pipe inserted into the top edge of a vertical post positioned below the former vertical post. The joint comprises a base portion and a flange portion oriented at a right angle with respect to the from base portion. The bolt passes through a hole of the base portion of the joint and a hole of the vertical post and is screwed into a screw hole of the steel pipe to secure the joint to the vertical post.

Abstract: A device for forming a framework of a wooden building includes a steel made square tube which is capable of tightly receiving a top portion of a post in a lower portion of the tube and a bottom portion of another post in an upper portion of the tube. The device also includes a joint which has a belt-shape base portion situated in the vertical direction and a flange portion projecting perpendicularly from the center of the base portion. The device further comprises a bolt and joint stick. The bolt attaches the base portion of the joint to the square tube. The joint stick passes through a hole of a transverse lumber and an opening of the flange portion of the joint, while the flange portion is inserted in a slit at the edge portion of the transverse lumber.

Abstract: A main body, composed of a pair of L-shaped metal plates combined with each other in a back-to-back positional relation, is secured to a first wooden member with a U-shaped stopper by bolts and nuts. A second wooden member is secured with the first wooden member as a vertical slit made at the edge portion thereof receives the combined metal plates secured to the first wooden member, and joint bars are firmly inserted into holes and openings made through the second wooden member and the combined metals accordingly.
