Abstract: Joint apparatus for construction members and a building construction are provided with standardized joint members including at least one of a basic joint member including a fitting protrusion of an approximately cross-figured lateral sectional shape, an end plate portion connected at a top or a bottom face of the fitting protrusion, and a projection extending upwardly from the end plate portion for fitting a groove of approximate straight line or cross-figured lateral sectional shape. The joint apparatus is suitable for coupling standardized precut timbers capable of use for construction members so as to form a framework of a building. The joint apparatus for construction members can effectively construct a building in which characteristics of both the conventional frame work method and the built-up wall method are mixed together.

Abstract: A basic joint member and a plurality of application joint members are formed so that a side plate portion or end plate portion is fitted to the end face of a construction member constituting a post, a beam or the like and a coupling plate portion extending from the side plate portion or end plate portion orthogonally to the side plate portion or end plate portion is fitted in a groove formed in the end face of the construction member or is gripped between construction members including two parallel members, and the connecting plate portion is clamped by a clamping member. The basic member containing a longitudinal construction member is combined with and connected to at least one application joint member for a lateral construction member, a lateral construction member orthogonal to the first-mentioned lateral construction member and an oblique construction member to construct a joint apparatus for construction members.
