で不利な点がある。The welding work requires a high level of skill and quality control is not easy. In addition, the number of skilled workers is decreasing and aging every year, and automation of welding or non-welding is required. Therefore, as a configuration for easily obtaining a joint with stable quality, various structures in which a column and a beam are bolt-joined using a special joining device have been proposed. However, since the square steel pipe column has a closed cross-sectional shape, it is necessary to devise a bolt tightening mechanism to use a normal high-strength bolt. For example, there are disadvantages in the construction, such as the nuts must be placed in advance in the rectangular steel pipe pillars or the screws must be cut off.

る。According to this construction, since the one-side bolt is used, it is possible to perform bolt connection from the outside with respect to the rectangular steel pipe column having the closed cross section, and the welded structure has a stable quality at the joint. Further, regardless of whether the rectangular steel pipe column is a closed cross-section column, it is sufficient to perform a perforating process for inserting the one side bolt into the column, and the structure is simple and the construction is easy. When the web of a beam made of H-section steel is joined to a column by a beam joining metal article made of a split tee or an angle, a pin joint structure is formed. Further, when the upper and lower flanges of the beam are joined to the column by a pair of split tees, a rigid joint structure can be obtained. When a pair of split tees are used, even if the pillar has a welded seam, by disposing the split tee at a position where the seam is removed, the split tee can be brought into close contact with the pillar and reliable joining can be achieved. In addition, when mortar is filled in the portion of the pillar that corresponds to the beam, the proof stress of the beam-joined portion of the pillar is improved, and the reinforcement of the diaphragm or the like can be eliminated. Mortar is injected into the space inside the pillar between the weir plates from the mortar injection port below, and the outflow is confirmed from the confirmation hole. As a result, the mortar can be easily and reliably filled and the filling can be managed.

かも仮締め後に再度締め付け力を加えることもできる。When the one side bolt having the above-mentioned valve sleeve is used, it is tightened as follows. By turning the nut of the one-sided bolt inserted through the bolt insertion hole in the tightening direction, the valve sleeve is pressed against the pin head via the shear washer and the grip sleeve, which causes the valve sleeve to be plastically deformed outward in a brim shape. . The collar-shaped plastically deformed portion engages with the inner surface of the rectangular steel tube column or the like, and further tightening of the nut causes the shear washer to be pressed by the grip sleeve and sheared. In this state, the pipe wall of the rectangular steel pipe column and the beam joint metal are tightened between the nut and the flange-shaped deformed portion of the valve sleeve. The part protruding to the outside of the pin is divided by the break groove. According to this one-sided bolt, due to the shearing of the shear washer, the tightening force between the nut and the flange-shaped deformed portion of the valve sleeve directly becomes the tightening force that sandwiches the square steel pipe column and the beam-joined metal fitting, and a strong tightening force. Is obtained. Also, in the case of this one-sided bolt, the tightening force is introduced by rotating the nut, so it can be tightened with a simple tool such as a rotary electric tool, and the tightening force can be applied again after temporary tightening. it can.

The one-side bolt 1 has a pin 2, a valve sleeve 3, a grip sleeve 4, a shear washer 5, a receiving washer 15, and a nut 6 which are arranged on the outer periphery of the pin 2 in order from the pin head 2a side. And The pin 2 has a fractured groove 2d in the middle of the threaded portion 2b following the round shaft portion 2e, and a pin head 2a having a diameter slightly larger than the pin diameter at the tip. Further, a short pin tail 2c is provided following the screw portion 2b. The pin tail 2c is
The outer diameter surface is formed as a non-slip uneven surface, for example, a large number of teeth arranged in the axial direction are formed in the circumferential direction. The valve sleeve 3 is made of a material softer than that of the grip sleeve 4, and is plastically deformable outward in the form of a brim by the load of the axial force. For example, the grip sleeve 3 is made of a hard steel alloy and the valve sleeve 4 is made of a soft steel alloy.

Tighten. As a result, a compressive force acts between the pin head 2a and the shear washer 5 to pinch the grip sleeve 4 and the valve sleeve 3, and the valve sleeve 3 at the tip starts to plastically deform outward in a brim shape. That is, barbing occurs. When the round shaft portion 2e of the pin 2 is stepped, the above-mentioned barbing occurs until the step portion 2f is engaged with the grip sleeve 4. When the nut 6 is further tightened, the shear washer 5 is sheared and the grip sleeve 4 enters the receiving washer 15. As a result, when the flange-shaped deformed portion 3a of the valve sleeve 3 engages with the inner wall surface of the rectangular steel pipe column 21, the pipe wall of the rectangular steel pipe column 21 and the beam-joined metal fitting are connected between the nut 6 and the flange-shaped plastically deformed portion 3a. A tightening axial force is introduced into 23. When the nut 6 is further tightened and rotated, the pin tail 2c breaks in the breaking groove 2d with a predetermined axial force introduced (FIG. 3 (B)).

と同様に締め付けを行うことができる。When this one side bolt 1 is used,
Can be firmly joined. That is, share washer 5
Due to the shearing, the tightening force between the nut 6 and the flange-shaped deformed portion 3a of the valve sleeve 3 is the same as that of the rectangular steel pipe column 2
1 and the beam joining hardware 23 are sandwiched, and a strong tightening force is obtained. Also, this one side bolt 1
In this case, the following advantages can be obtained. First, since the flange-shaped deformed portion 3a of the valve sleeve 3 serving as the head of the bolt spreads widely, the contact pressure with the rectangular steel pipe column 11 becomes small, and the bolt hole diameter has a relatively allowable width. For example, the problem that the edge of the bolt hole is deformed by the contact pressure and the bolt head is fitted is unlikely to occur. Along with that, the load bearing capacity of the bolt head including the collar-shaped deformed portion 3a is improved, and the one-side bolt 1
The tightening force is improved and the efficiency is improved. Moreover, since the nut 6 is tightened by turning it, double tightening or
Can be tightened again. In addition, an electric device is used for tightening, and it is easy to handle at the site. With the one-side bolt 1'which is tightened by the pulling operation described later with reference to FIG.
In order to obtain sufficient axial force required for rigid connection of buildings, for example, about 20 kilograms of hydraulic tightening tool is required, but the rotary electric device mentioned above is lighter than about 10 kilograms. It's done. Moreover, heavy hydraulic piping is not required, and only an electric cord is needed, which dramatically improves workability. In addition, the hydraulic unit does not need to be prepared, and tightening on high floors can be performed easily. In addition, this one-side bolt 1 requires only a short pin tail 2c to be discarded after tightening, and waste of material is small. Further, the number of parts constituting the bolt is small, which results in cost reduction.
