Description of the Related Art Generally, a flange joint having a flange portion having a diameter larger than the outer diameter of a steel pipe is used at a connection end of a steel pipe structure such as a power transmission tower. An example will be described with reference to FIG. The flange joint 13 is
The joining surfaces of the joint members 14 and 15 having the flange portions 16 having a diameter larger than the outer diameters of the steel pipes 19 and 20 to be joined are overlapped, the bolts 17 are passed through a plurality of bolt holes opened in the flange portions 16, and the nuts 18 are removed. The steel pipes 19 and 20 are joined by tightening.

鋼管構造物自体及び構築のためのコストがかさむ。[0004] Further, since the position at which the pair of joint members are fastened with bolts and nuts is outside the outer diameter of the steel pipe,
In a steel pipe structure such as a steel tower, a bending stress is applied to a joint bolt in addition to a tensile stress, so that a load increases. Therefore, it is necessary to use many bolts and nuts to secure the fastening force of the joint as a structure. Also,
The costs for the steel pipe structure itself and its construction are increased.

欠点がある。As described above, in the conventional method of constructing a steel pipe structure using a flange joint, the weight of the joint portion increases, and tensile stress and bending stress are applied to the joint bolt. However, there are drawbacks such as that many bolts and nuts are required to secure the fastening force of the joint.

手部材間を締結する。In order to achieve the above object, a joint for a steel pipe structure according to the present invention has a notch in the entire outer peripheral surface of a joint surface of a pair of joint members joined to a pipe end of a steel pipe. A recess is provided, or a plurality of cut-out recesses having a predetermined width are arranged at intervals. A plurality of screw holes drilled in the axial direction with mutually opposite screws with respect to the mating joint member are arranged at circumferentially equal parts of the cutout recess. Then, bolts having oppositely threaded portions provided in the upper half portion and the lower half portion are screwed into the respective screw holes of the joint members facing each other to fasten the joint members.

要である。As the bolt for joining the joint member, a bolt having a hexagonal portion for turning a bolt between upper and lower half reverse screws is used. Further, the provision of the screw holes for screwing the bolts in the cutout recesses on the joint surface of the joint member is necessary for turning and fastening the bolts by utilizing the space formed between the recesses of the butted joint members. It is.

るから、継ぎ手自体の軽量化が図れる。By arranging a screw hole for screwing a bolt for fastening the joint on the thickness extension line of the steel pipe, the outer diameter of the joint can be made smaller than that of a conventional joint. And, by reducing the diameter of the joint, the weight of the joint itself and the steel pipe structure to be constructed can be reduced. Since the bending stress applied to the bolt is removed and only the tensile stress is applied, the size and the number of bolts used for securing the joint fastening force as the steel pipe structure can be reduced, and the bolts can be measured. Furthermore, since there is no flange portion, the outer diameter of the joint can be reduced, so that the weight of the joint itself can be reduced.
