That is, the pillar 101 is cut at the height of the flange of the beam 102A, and a diaphragm 103 for reinforcement is provided at the cut portion.
A, 103A is welded so that its outer peripheral portion is exposed outside the tube wall, or a reinforcing diaphragm 103B is welded to the inside of the column 101 at the flange height of the beam 102B.

As another conventional example, there has been proposed a method in which an end plate or the like of a beam is joined to a steel pipe column using a one-side bolt. In this case, the one side bolt shown in FIG. 17 is used. The one-side bolt 80 has a head portion 82a formed by plastic deformation at the front end of a sleeve 82 over the pin 81 and a large-diameter portion 82 at the rear end.
b, the tube wall of the steel pipe column 90 and the end plate 91 are sandwiched therebetween.

ため締め付け力が弱く、強度面で十分でなかった。However, with the structure in which the beam 102A is bolted via the bracket 104 as in the example of FIG. 16, the number of members and the number of welding points are increased, and time and labor are required for welding and cutting. Take it. Moreover, the bracket 1
Since the 04 protrudes, the efficiency of transportation from the factory to the site is poor. In the case of a structure in which the end of the beam 102B is directly welded to the pipe wall of the column 101, on-site welding is required. Welding requires advanced technology, quality control is not easy, and welding technicians tend to be short. Therefore, it is desired to eliminate on-site welding. For this reason, various types of bolt and column joints have been proposed using a special joint device.
The square steel tubular column has a closed cross-section, and in order to use a normal high-strength bolt, it is necessary to devise a bolting mechanism. For example, there are disadvantages in construction, such as the necessity of preliminarily installing a nut in a square steel pipe column or cutting a screw. With the joint structure using the one-side bolt 80 in FIG. 17, the disadvantage in the above construction is eliminated.
However, since the one-side bolt 80 is to be tightened between the head portion 82a of the integral sleeve 82 and the large-diameter portion 82b, the axial force introduced into the sleeve 82 at the time of tightening is due to the plastic deformation of the head portion 82a. Even after the formation, it is in a state of being added to the entire sleeve 82. Therefore, the axial force acting as the tightening force of the steel pipe column 90 and the end plate 91 is a value obtained by subtracting the compressive force acting on the intermediate portion 82c of the sleeve 82 from the load introduced by the tool. Therefore, the fastening force was weak, and the strength was not sufficient.

Another object of the present invention is to provide a beam-column joint structure using one-side bolts, which can be easily joined to a steel pipe column having a closed cross section by an operation from the outside.

In particular, when the reinforcing member is a plate-like member superposed on the inner surface of the steel pipe column, and the one-side bolt is penetrated through the joining hardware, the pipe wall of the steel pipe column, and the reinforcing member, as described above, the steel pipe column on the upper and lower floors is used. It is easy to perform the joining of the beams and the joining of the beams at the same time. If the receiving member for mounting the joint metal at the end of the steel beam to the steel pipe column is joined with one-side bolts, the receiving member can be attached to the steel pipe column with a simple operation without using a jig, and the receiving member can be attached. The joint hardware of the steel beam can be temporarily placed at the time of construction with the member.

受け部材で建方時に鉄骨梁の接合金物を仮置きできる。According to the present invention, there is provided a beam-to-column joint structure using one-side bolts, wherein a reinforcing member is provided on an inner surface of a beam-joint portion of a steel pipe column.
Since the ends of the steel beams are joined by one-side bolts that penetrate through these joints and the pipe wall of the steel pipe column through joints provided or attached to the ends of the steel beams, a simple structure is used. With this configuration, the strength and rigidity of the joints of the columns can be ensured, no on-site welding is required, and it is possible to easily join the steel tube columns with a closed cross section by work from the outside. In addition, since there is no protrusion on the outer surface of the steel pipe column, the transport efficiency is improved. In particular, as a one-sided bolt, a pin, a head forming member provided at the tip of the pin and capable of being plastically deformed in an expanded state, and the head forming member axially movably fitted to the pin in the axial direction. A sleeve for transmitting a pressurizing force for plastically deforming the sleeve, a shearing member that engages with the rear end of the sleeve and shears with a predetermined axial force, and the expanded member provided at the rear of the pin. Since a member having a nut that sandwiches the member to be fastened with the head forming member is used, firm joining can be performed. In the case of the invention of claim 2, a steel beam is arranged at the joint between the upper steel pipe column and the lower steel pipe column, and this steel beam is joined to both the lower end of the upper steel pipe column and the upper end of the lower steel pipe column. Therefore, the joining of the steel pipe columns and the joining of the beams on the upper and lower floors can be performed simultaneously with one-side bolts. In particular, when the reinforcing member is a plate-like member superposed on the inner surface of the steel pipe column, and the one-side bolt is penetrated through the joining hardware, the pipe wall of the steel pipe column, and the reinforcing member, as described above, the steel pipe column on the upper and lower floors is used. It is easy to perform the joining of the beams and the joining of the beams at the same time, and a firm joining can be performed. In the case of the invention of claim 3, since the reinforcing member is a diaphragm, a stiffening effect against a lateral load from the beam is high. When a diaphragm is provided in a steel pipe column, it is difficult to use it together with back nut welding, etc., or it takes a lot of time, but with the combination of one side bolt and diaphragm, with a simple configuration and simple work,
A solid joining structure results. In the case of the invention of claim 4, since the reinforcing member is a rib extending in the longitudinal direction, a high stiffening effect can be obtained also in this case. Further, since the ribs extend in the vertical direction, unlike the case of the diaphragm, even when beams having different beam structures are joined in each direction, the stiffening effect of the steel pipe column can be secured for any of the beams. In the case of the invention of claim 5, since the reinforcing member is a plate-shaped member superposed on the inner surface of the steel pipe column, reinforcement against a cross-sectional defect of the pipe wall of the steel pipe column by the insertion hole of the one-side bolt can be obtained. In the case of the invention of claim 6, since at least the beam joint in the steel pipe column is filled with concrete, the reinforcing effect is further improved. In the case of the invention of claim 7, since the receiving member is joined to the steel pipe column with a one-side bolt, the receiving member can be attached to the steel pipe column with a simple operation without using a jig, and the receiving member can be used. At the time of erecting, the joint of the steel beam can be temporarily placed.
