Description

  The present invention mainly relates to a joining means for fixing an attachment member (steel beam, etc.) to a base member (steel pipe pillar, etc.) and a nut fastener used for the joining means in a building constructed using steel pipe pillars or steel beams. Further, the present invention relates to a tightening ring and a washer that are inserted into a chin nut, an anchor bolt, and a fixing bolt.

  In the construction of a building, as a joining means for attaching an attachment member (steel material, wood, panel material, etc.) to a base member (concrete, steel, wood, etc.), the foundation member E is larger than the fixing bolt B as shown in FIG. A through hole P having a diameter is drilled in an attachment member F with a hole Q having a diameter larger than that of the fixing bolt B, and is fixed using the fixing bolt B and a nut N, or as shown in FIG. A hole Q having a diameter larger than that of the fixing bolt B is provided in F, and a female screw G that is screwed to the fixing bolt B is provided in the base member E. The fixing bolt B is provided in the female screw G of the base member E from the hole Q in the accessory member F. Then, a through hole P is drilled in the base member E and a through hole Q is drilled in the accessory member F, and a nut fastener 1 is attached to the through hole P as shown in FIG. The fixing bolt B is screwed into the nut fastener 1 attached to the base member E from the hole Q of the member F and fixed. It is known that.

  In the joining of a square steel pipe column and a steel beam, a column-beam joint cylinder covering the entire peripheral surface of the joined part of the square steel pipe column, and of the square steel pipe column hole among the holes formed so as to penetrate both of them. A plurality of female screw members fixed from the inner side, and an end plate formed with holes corresponding to the female screw members and fixed to the ends of the steel beam, the end plate being brought into contact with the column beam joining cylinder It is known that a male screw member is screwed into a female screw member through each hole in a contact state, and both are fixed.

  The joint structure using high-strength bolts has a problem that the rigidity of the joint is relatively low because the performance of the joint is exhibited by the out-of-plane bending resistance of the square steel pipe column. For this purpose, concrete is filled into the square steel pipe column to increase the rigidity of the joint. However, when concrete is simply filled into a square steel pipe column, the resistance of the filled concrete can be expected against the compressive force from the steel beam flange, but the tensile steel is not affected by the inside of the side of the square steel pipe column. Only the improvement in performance by suppressing deformation of the joint can be expected, and the improvement in the joint performance by filling with concrete is small.

  As a column-beam joint type for CFT-structured square steel pipe columns and steel beams, column-beam joints with vertical ribs inside square steel pipe columns are known. In this case, the presence of the longitudinal ribs causes resistance of the filled concrete to the tensile force from the beam flange. Therefore, it can be expected that the joint performance is improved as compared with the case where the longitudinal ribs are not provided. However, it is necessary to weld the longitudinal ribs to the inside of the square steel pipe column, and the processing burden such as welding is cut and welded near the joining stage of the square steel pipe column is heavy, and the cost is high. There is a problem to become.

As a column-beam joint type for CFT-made square steel pipe columns and steel beams, studs are provided inside a square steel pipe column with a diaphragm installed, and a steel beam is welded to the diaphragm. A column-beam joint is known in which vertical ribs are welded and cylindrical vertical ribs are arranged to hold the vertical ribs.
In these column-beam joints, the diaphragm and stud, vertical ribs, and the presence of cylindrical vertical ribs cause resistance of the filled concrete against the tensile force from the steel beam flange. Compared to a square steel pipe column not provided with a cylindrical vertical rib, an improvement in the joining performance can be expected.
However, studs and vertical ribs need to be welded to the inside of the square steel pipe, and the welding process is performed at the manufacturing stage of the square steel pipe or by cutting the vicinity of the joint of the square steel pipe, or in addition, processing for the diaphragm There is a problem that the burden of welding or the like is large and the cost is high.
