2. Description of the Related Art In recent years, by building a framework by connecting building members using a joint device, the connection of building members can be completed only by a simple operation of using fastening means such as simple bolting. A technique has been proposed in which various types of houses can be successively constructed according to a demand of a consumer using a small number of standard products, as if combining block toys of various shapes.

[0003] For example, Japanese Patent Application Laid-Open No. 63-233136 discloses a joint device for a building member for connecting a floor beam, a column and the like. This joint device is composed of a basic joint member and first and second applied joint members selectively assembled thereto. That is, as shown in FIG. 6, the column base metal member 1 as the basic joint member is formed by welding a pair of side plate portions 1a facing each other at a predetermined interval to an intermediate plate portion 1b serving as a fastening portion to the column 2. It is formed in a connected horizontal section H shape. An end plate portion 1c extending in a direction substantially perpendicular to the surface of the side plate portion 1a and the surface of the intermediate plate portion 1b is welded to the bottom of the vertical groove portion of the column base metal fitting 1 by welding.

On the other hand, the base connection plate 3 as the first applied joint member has its side end joined to the outer surface of the side plate portion 1a of the column base metal fitting 1 by welding or the like.
A plate portion extending from the outer surface of the side plate portion 1a to the same plane as the intermediate plate portion 1b and serving as a fastening portion to the base 4. Further, the beam connecting hardware 5 as the second applied joint member can be coupled to an end of the column 2 which is inserted between the side plates 1a and 1b of the column base hardware 1 and coupled by a fastener. A side plate portion 5a serving as a fastening portion to the column 2 and a connecting plate portion 5b extending from a central portion of the surface of the side plate portion 5a into a plane substantially orthogonal to the surface and serving as a fastening portion to the floor beam 6 are provided.

[0005] For example, to fasten the base 4, a groove 4 a formed in advance at the center of the joint end of the base 4 is formed.
Then, the base connection plate 3 is inserted, and the bolts inserted from the insertion holes on one side of the base 4 are inserted through the insertion holes of the base connection plate 3,
