が不要になる。The steel frame member 2 using the joining hardware 10 of the embodiment
As shown in FIG. 3, in the joint portion in which 1, 22, 23, and 24 are joined, the stress transmitted by the flange 21a of the steel frame member 21 is a portion where the upper and lower disk-shaped portions 12 and 13 have large diameters. 12a, 13a is directly transmitted to the steel member 21
Of the web 21b is transmitted to the post-installed gusset plate 15 and then to the large diameter portions 12a, 12b, 13a, 13b of the disk-shaped portions 12, 13 of the joint metal 10 through the gusset plate 15. At the same time, it is also transmitted to the small-diameter portions 12b and 13b of the disk-shaped portions 12 and 13 of the metal joint 10 through the joint of the step portion 14 of the gusset plate 15 to the outer peripheral surface 14a. Therefore, the disk-shaped parts 12 and 1 of the joining hardware 10 are
Since large stress acts on the small-diameter portions 12b and 13b of 3, the thickness t 2 of the large-diameter portions 12b and 13b is made larger than the thickness t 1 of the large-diameter portions 12a and 13a to withstand the large stress. I am trying to get it. Further, the gusset plates 15 and 16 are simply joined to the inner side surfaces 12a 1 and 13a 1 of the large diameter portions 12a and 13a of the disk-shaped portions 12 and 13 and the outer peripheral surface 14a of the step portion 14 by fillet welding w 2. , Small-diameter portions 12b, 1 of the disk-shaped portions 12, 13
Since the gusset plates 15 and 16 are not provided in the space between the inner side surfaces 12b 1 and 13b 1 of 3b, welding work in a narrow place is unnecessary.

る。The present invention has the following effects (a) to (g) by having the structure described in the claims. (A) Since the one according to claim 1 is manufactured by casting the joint metal with cast steel having good weldability, it is easy to manufacture, and the joint metal is columnar above and below the columnar portion in the central portion. The casting is easy because it has a simple shape in which the disc-shaped portions are integrally connected to the respective portions. The flange edges of the steel members are joined by welding to a plurality of peripheral portions of the upper and lower board-like parts of the joint metal, and the edges of the webs of the respective steel members and the upper and lower board-like parts are joined. Since it is only necessary to join the edges of the gusset plate that is joined to the inner surface by welding, it is possible to manufacture a steel frame member by simply cutting the steel material to a specified length, and no attachment plate or bolts / nuts are used for joining. Therefore, the joint portion of the steel frame member can be reduced in weight. (B) According to the second aspect, the stress transmitted by the flange of each steel frame member can be directly transmitted to the large-diameter portions of the upper and lower disc-shaped portions, and the stress of each steel frame member can be increased. Since the stress transmitted by the web can be transmitted to the large and small diameter portions of the upper and lower disc-shaped portions and the small and large diameter portions of the upper and lower disc-shaped portions through the gusset plate, The stress is not concentrated on the joining portion of the plate-shaped portion of the metal object, and the metal object can be made small and lightweight. (C) According to the third aspect, it is possible to stabilize the shapes of the upper and lower disc-shaped portions of the joined metal article in which the steel frame members are not joined. (D) According to the fourth aspect, a plurality of steel frame members can be easily joined via a single joint metal. Since it is not necessary to perform special processing on the joint portion of the steel frame member, the joint portion of the steel frame member can be formed at low cost. (E) According to claim 5, it is only necessary to weld the edges of the upper and lower flanges of the steel member to the peripheral edges of the upper and lower disk-shaped parts of the joined metal article by welding. It is possible to join a plurality of steel members at various angles by using the joining hardware of (1). (F) According to the sixth and seventh aspects, it is not necessary to perform welding work in a narrow space between the inner surfaces of the lower and upper disc-shaped portions having small diameters. (G) According to the eighth and ninth aspects, the joint metal can be easily unitized, and various steel members can be jointed at various joint angles using the same joint metal.
