2. Description of the Related Art Generally, in a steel frame structure, since the beams are joined to the columns through the column-beam joining hardware having a complicated shape, the joining is not only troublesome, but also construction is difficult. There was a problem such as a decrease in accuracy. In addition, since the beam composition of beams at one joint is not the same, multiple types of pillar / beam joint hardware with different shapes are required, and the shape of the pillar / beam joint hardware is complicated. In that case, there is a problem that the production is not easy and the production cost increases.

The present invention has been made in order to solve the above-mentioned problems, and makes it possible to easily manufacture a post / beam joint metal fitting and also to facilitate the joint between the post and the beam. The purpose is to provide a pair of column-beam joint structure.

[0004]

In the column-beam joint structure of a steel frame assembly according to the present invention, the column-beam joint metal is formed in a rectangular cross section, and its width and height are set to the beam width of the beam. And the end plate and the pillar which are formed in the same manner as the beam-bonded metal, and the side surface and the upper and lower ends of the pillar and the beam-bonded metal article are respectively touched to the ends of the pillar and the beam-bonded metal piece. It is constituted by attaching a joint metal piece and bolting the end plate and the pillar joint metal piece to a side surface portion and upper and lower end portions of the pillar / beam joint metal piece by a plurality of joint bolts, respectively.

【Example】

Example 1. 1 to 5 show an embodiment of a column-beam joint structure of a steel frame assembly according to the present invention. In the drawings, reference numeral 1 is a beam made of rectangular steel pipe, 2 is a column of upper and lower floors made of rectangular steel pipe,
3 is a beam 1 and 1 on the left and right, columns 2 and 2 on the upper and lower floors, and a pillar / beam-joint metal fitting for joining the beam 1 and the pillar 2 to each other. 4 is for joining the beam 1 to a side surface of the pillar / beam-joint hardware 3. The end plates 5 attached to the ends of the beams 1 are columns attached to the ends of the columns 1 of the upper and lower floors in order to join the columns 1 of the upper and lower floors to the upper and lower ends of the column-beam joint hardware 3. It is a joint metal.

Reference numeral 6 is an end plate 4 at the end of the beam.
Is a joint bolt for joining the column / beam joint metal 3, and 7 is a joint bolt for joining the column joint metal 5 at the column ends of the upper and lower floors to the column / beam joint metal 3.

The pillar-beam jointing hardware 3 is formed in a rectangular cross-section and is formed so that its diameter and height match the beam width and beam formation of the beam 1, and end plates are formed at both upper and lower ends. 8 and 8 are attached horizontally by welding. In addition, a back plate 9 is provided on the inside of each side surface of the pillar / beam joint hardware 3.
9 is attached by welding.

Further, a plurality of bolt holes 10, 10 through which the joining bolts 4 can penetrate are formed on each side surface of the pillar / beam joint metal 3, and the back plate 9, 10 is continuous with the bolt holes 10, 10. A plurality of screw holes 11, 11 into which the joining bolt 6 can be screwed are formed in the screw 9.

Instead of attaching the back plates 9 and 9, fixing nuts 12 and 12 to which the joining bolts 6 can be screwed may be welded to the back side of the bolt holes 10 and 10 (see FIGS. 6, 7 and 8). .

A plurality of screw holes 11 are formed in the upper and lower end plates 8 of the pillar / beam joint metal 3 so that the joint bolts 7 can be screwed therein.
Are formed.

The end plate 4 is attached to the end portion of the beam 1 so as to make a surface contact with the side surface portion of the pillar-beam jointing hardware 3.
Further, the end plate 4 is formed with a plurality of bolt holes 13, 13 through which the joining bolt 6 can pass. Further, an opening 14 is formed in the side portion of the beam 1 so that a hand can be inserted into the back side of the end plate 4 when the joining bolt 6 is tightened.

The end plate 4 is attached to the side surface of the pillar / beam joint metal fitting 3, and is inserted from the bolt hole 13 into the screw hole 11 of the back plate 9 in the pillar / beam joint metal fitting 3 via the bolt hole 10. The joining bolts 6 are screwed together, and the beam 1 is joined to the side surface portion of the pillar / beam joining hardware 3 by such a configuration.

The column-joining metal piece 5 has a vertical rib 5a having a cross-shaped cross section which is continuous in the vertical direction, and a column-beam joining metal piece 3 at the end of the vertical rib 5a.
And an end plate 5b horizontally attached to the end plate 8 so as to make a surface contact.

The end plate 5b is formed with a plurality of bolt holes 15, 15 through which the joining bolt 6 can pass.

Then, the pillar-bonding metal 5 is attached to the ends of the upper and lower pillars 2 by welding, the end plates 5b are attached to the end plates 8 at the upper and lower ends of the pillar-beam bonding metal 3, and the bolts are attached. The joining bolt 7 is screwed into the screw hole 16 of the end plate 8 through the hole 15, and the pillar 2 on the upper and lower floors is joined to the pillar / beam joint metal 3 by such a structure.

Example 2. 9 and 10 show another embodiment of the column-beam joint structure of the steel framework according to the present invention, in which the beam 1 joined to the column-beam joint hardware 3 is attached to the left and right of the upper and lower flanges of H-shaped steel. The H-section steel with a lip having the lips 1a, 1a at the edge is used, and the opening 14 is omitted because the H-shaped steel with a lip is easily accessible to the back side of the end plate 4. The other structure is almost the same as that of the first embodiment.

[0017]

As described above, according to the pillar / beam joint structure of the steel frame assembly according to the present invention, the pillars on the upper and lower floors are the end plates of the pillar-joint metal fittings attached to the pillar ends.・ Besides touching the upper and lower end plates of the beam-bonded metal fittings, they are bonded by bolting them with bonding bolts, and the beam makes the end plates attached to the end of the beam surface-touch the pillar / beam-bonded metal fittings, as well as the bonding bolts. Because it is joined by bolting with,
There is an effect that the pillar and the beam can be easily joined via the pillar-beam joint metal, and the generation of stress such as twist in the beam is prevented, and the joint strength can be prevented from lowering due to the twist.

Further, since the diameter and height of the pillar / beam-bonded metal piece and the beam width and beam formation of the beam are formed to coincide with each other, the types of the beam and the pillar / beam-bonded metal piece are unified, and the beam and the pillar-metal piece are unified. -It is possible to significantly reduce the number of beam-bonded metal parts, and to manufacture column-beam metal parts easily and at low cost.
