Description

本発明は、鉄骨軸組の仕口構造及び角型鋼柱に角型鋼梁を接合するための継ぎ手部材に係り、特に、作業性と強度向上を図ることができる鉄骨軸組の仕口構造及び角型鋼柱に角型鋼梁を接合するための継ぎ手部材に関する。     The present invention relates to a joint structure for a steel frame and a joint member for joining a square steel beam to a square steel column, and more particularly to a joint structure and a corner of a steel frame capable of improving workability and strength. The present invention relates to a joint member for joining a square steel beam to a shaped steel column.

従来、中空の角型鋼柱にＨ鋼の梁を接合する鉄骨軸組の仕口構造がある（例えば、非特許文献１参照）。
これは、中空の角型鋼柱の中途を切断し、ダイヤフラムと称される部材を介して中空の角型鋼柱にＨ鋼の梁を溶接して接合し、仕口の剛性を高めるようにしている。
しかしながら、この鉄骨軸組の仕口構造では、中空の角型鋼柱の中途を切断しなければならず、作業性が悪く、しかも、中空の角型鋼柱に接合される梁にＨ鋼を使用するため、該梁は横からの荷重（水平荷重）に弱いという問題点があった。
編集 社団法人日本鋼構造協会 「実例でわかる工作しやすい鉄骨設計（第２版）」第４７頁 2. Description of the Related Art Conventionally, there is a steel framed joint structure in which a steel beam is joined to a hollow square steel column (see, for example, Non-Patent Document 1).
This cuts the middle of a hollow square steel column and welds and joins a H steel beam to the hollow square steel column via a member called a diaphragm to increase the rigidity of the joint. .
However, in this steel-framed joint structure, the middle of a hollow square steel column must be cut off, the workability is poor, and H steel is used for the beam joined to the hollow square steel column. Therefore, the beam has a problem that it is weak against a lateral load (horizontal load).

また、中空の角型鋼柱２（角型鋼柱２の長さは、例えば、２５ｍ）には、図３、図８乃至図１２に示すように、耐力を高めるために、所定間隔（例えば、１ｍ）毎に、挿入孔２ａを介して補強材（節材）２０が中空の角型鋼柱２の長手方向を横断するように挿入され、挿入孔２ａ、他の孔２ｂ、２ｃ、２ｄを介して溶接により中空の角型鋼柱２に固着されている。溶接により固着された部位をＹで示す。
なお、図９乃至図１２に示すように、溶接する際、裏当て金を使用しないで溶接できるようになっている。中空の角型鋼柱２内には、図示しないコンクリート等（グラウト材）を注入すると良い。補強材（節材）２０と補強材（節材）２０との間には、補強材（節材）２０の中心に設けた孔２０ａを介して図示しないコンクリート等（グラウト材）が充填されるようになっている。
即ち、中空の角型鋼柱２内にコンクリート等（グラウト材）を注入することにより、補強材（節材）２０の持つ拘束力により中空の角型鋼柱２内の面内座屈が起こりにくく、特に、地震等において、中空の角型鋼柱２に掛かる曲げモーメント、剪断力、軸力共にその耐力が極めて大きくなり、また、中空の角型鋼柱２に掛かる垂直荷重による座屈力に対するその耐力が大変高くなり、中空の角型鋼柱２内にコンクリート等（グラウト材）が内在することにより、コンクリート等（グラウト材）が空気に触れないことにより酸化を防いで、コンクリート等（グラウト材）本来のアルカリ性をより長期に亘って維持することができ、更に、角型鋼柱２、継ぎ手部材３及びコンクリート等（グラウト材）の合成剛性力によって仕口部の角型鋼梁４による応力伝達が極めて高くなる等の利点を有する。
なお、耐力が不足しない場合には、中空の角型鋼柱２内の補強材（節材）２０、図示しないコンクリート等（グラウト材）を適宜省略することもできる。
逆に、中空の角型鋼梁４において、耐力が不足する場合には、中空の角型鋼柱２と同様、中空の角型鋼梁４内に、補強材（節材）２０、図示しないコンクリート等（グラウト材）［図示しないコンクリート等（グラウト材）は、補強材（節材）２０と補強材（節材）２０との間、全てでなく部分的に設けても良い。］を適宜設けるようにしても良い［図９乃至図１２に示す（ ）は、中空の角型鋼柱２を中空の角型鋼梁４に置き換えた場合を示している。］。 Further, as shown in FIGS. 3 and 8 to 12, the hollow square steel column 2 (the length of the square steel column 2 is, for example, 25 m), as shown in FIGS. ), The reinforcing member (node member) 20 is inserted through the insertion hole 2a so as to cross the longitudinal direction of the hollow square steel column 2, and is inserted through the insertion hole 2a and the other holes 2b, 2c, 2d. It is fixed to the hollow square steel column 2 by welding. A portion fixed by welding is indicated by Y.
In addition, as shown in FIG. 9 thru | or FIG. 12, when welding, it can weld without using a backing metal.

Between the reinforcing member (node member) 20 and the reinforcing member (node member) 20, concrete (not shown) (grouting material) is filled through a hole 20 a provided in the center of the reinforcing member (node member) 20. It is like that.
That is, by injecting concrete or the like (grouting material) into the hollow square steel column 2, the in-plane buckling in the hollow square steel column 2 is less likely to occur due to the restraining force of the reinforcing material (node member) 20, In particular, in the event of an earthquake, the bending moment, shearing force, and axial force applied to the hollow rectangular steel column 2 are extremely large, and the resistance to buckling force due to the vertical load applied to the hollow rectangular steel column 2 is high. It becomes very high, and concrete etc. (grouting material) is contained in the hollow square steel column 2, so that the concrete etc. (grouting material) does not come into contact with the air to prevent oxidation. The alkalinity can be maintained for a longer period of time, and further, the square steel beam 4 of the joint is formed by the combined rigidity of the square steel column 2, the joint member 3 and the concrete (grouting material). That stress transfer has advantages such as very high.
In addition, when the proof stress is not insufficient, the reinforcing material (node member) 20 in the hollow square steel column 2, concrete (not shown), etc. (grouting material) can be omitted as appropriate.
On the contrary, when the proof stress is insufficient in the hollow square steel beam 4, the reinforcing material (member material) 20, concrete (not shown), etc. (in the hollow square steel beam 4) as in the hollow square steel column 2 ( Grout material) [Concrete or the like (grouting material) (not shown) may be provided between the reinforcing material (node material) 20 and the reinforcing material (node material) 20 instead of all. ] () Shown in FIGS. 9 to 12 shows a case where the hollow square steel column 2 is replaced with a hollow square steel beam 4. ].

The left rising portion 32d is joined to the hollow square steel beam 4 [see FIG. 17 (b)]. Similarly, the square beam side right side hole 4b for manual insertion is closed via a plate F 1 'positioned in the right side hole 32c' for right rising part for manual insertion and welded via the plate F 1 '. Accordingly, the right rising portion 32c is joined to the hollow square steel beam 4.
Moreover, the square beam side left side hole 4a for manual insertion and the right side hole 4b on the square beam side for manual insertion may be any one in some cases. In such a case, there is only one square beam side hole (4a or 4b) for manual insertion and corresponds to the square beam side hole (4a or 4b) for manual insertion on the surface of the right rising part 32c or the surface of the left rising part 32d. The site to be used is the side insertion hole (32c ′ or 32d ′) for the hand-inserted rising portion.
