った。2. Description of the Related Art Conventionally, in connection with a steel column and a steel beam, various structures have been used in which a metal fitting such as a gusset plate and a split tee and a tightening metal fitting such as a bolt / nut and a rivet are used. In particular, for example, the structure shown in Japanese Patent Application Laid-Open No. 59-85051, which uses a pair of half-break bolts (hereinafter referred to as paddle bolts) with a flat plate portion at one end and a bolt insertion hole narrowed, is used for the beam. Since the fastened paddle bolts are fastened to the column linearly, the tensile stress and compressive stress of the column-beam joint due to the bending of the beam can be transmitted to the column more smoothly than the structure of other metal joints. There is an advantage that can be done.
Therefore, it is often used, but it still has the following problems.

【発明が解決しようとする課題】パドルボルトによる柱
と梁の接合部を強化するため、パドルボルトを高強度
鋼、太径、肉厚にしても被接合材と該パドル部は一面剪
断形の接合であり、高力ボルトの剪断耐力に限界がある
ためボルトの本数を増加する傾向となる。しかるに直列
に並べたボルトの、列方向の剪断耐力は１本づつの負担
する剪断応力が不均一になるためボルトの本数に比例し
て、剪断耐力は上昇しない。In order to strengthen the joint between the column and the beam by the paddle bolt, even if the paddle bolt is made of high-strength steel, has a large diameter, and has a thick wall, the material to be joined and the paddle are of the one-sided shear type. Since this is a joint and the shear strength of the high-strength bolt is limited, the number of bolts tends to increase. However, the shear strength in the column direction of the bolts arranged in series is not uniform in shear stress, and therefore the shear strength does not increase in proportion to the number of bolts.
【０００４】又太径、肉厚にした場合金物が大型化し、
重量も増加して扱い難くなる。Further, when the diameter and the wall thickness are increased, the hardware becomes large,
The weight also increases and becomes difficult to handle.

にナットが干渉してこのままでは実施不可能である。In order to increase the strength of the joint portion by the paddle bolts, therefore, a two-sided shear type is conceivable, but the paddle bolts, especially the nuts interfere with each other and cannot be carried out as they are.

ィラーより構成してもよい。In a metal joint for a steel frame member, a paddle portion of a pair of two paddle bolts having a flat plate portion at one end and a bolt insertion hole narrowed to form a flange of the first steel member. Are clamped by bolts, the two pieces of paddle bolts are inserted into the flange of the second steel frame member, and the front and rear of the flange of the second steel frame member are tightly connected with nuts to attach the two pieces of paddle bolts to the first The main object is a metal joint for a steel frame member, characterized in that the second steel frame member is integrated. Further, in the tightening nut of the paddle bolt, a flange may be provided instead of the nut on the paddle portion side. Further, in the paddle bolt, the paddle portion on the upper side or the lower side may be lengthened to provide a bolt hole for temporary fixing to facilitate setting of the paddle bolt. In order to facilitate the setting of the paddle bolt and the accuracy of the steel member, a nut or a collar between the two pieces of paddle bolts to be used by overlapping or the paddle portion side of the paddle bolt for tightly connecting the paddle bolt and the second steel member Or a filler between the paddle portion of the paddle bolt and the first steel frame member.

にも応用出来る。(A) Since the paddle bolt is linearly fastened to the pillar, the stress from the beam is transmitted to the pillar more smoothly than other stresses. Therefore, it can be applied to large building structures.
