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. The joint stick is tightly inserted into holes of transverse member and the flange portion of the joint, joining the transverse member with the joint and thus with the vertical post.

Dependent claims

A device for forming a framework of a wooden building comprising:

a first tubular member which is tightly inserted in a hole formed at a bottom edge of a first vertical post, said hole being located along a vertical center line of said first vertical post;
a first fastener having an upper half portion screwed into a screw hole formed at a mouth portion of the first tubular member, the first fastener having a lower half portion screwed into a screw hole formed at a mouth portion of a second tubular member which is inserted into a top edge of a second vertical post positioned below the first vertical post for connecting the first and second tubular members and thus the first and second vertical posts in series;
a joint including a generally flat base portion positioned along at least one of the first and second vertical posts in the vertical direction, and a flange portion oriented at a right angle from a vertical center line of the base portion, both the base portion and the flange portion having a hole therein;
a bolt which extends through the hole of the base portion of the joint and a hole of said one first and second vertical post and is screwed into a screw hole of a corresponding one of the first and second tubular members for securing the joint to said one first and second vertical post, said screw hole of said one first and second tubular member being formed radially therein;
and
a second elongate fastener which is tightly inserted into a hole of a transverse member and the hole of the flange portion of the joint to interconnect the transverse member with the joint and thus with said one first and second vertical post, said flange portion being inserted into a slit formed at an edge portion of the transverse member.
