本考案は建築物等の鋼管コンクリート柱と鉄筋
コンクリート梁との接合部の構造に関するもので
ある。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the structure of a joint between a steel pipe concrete column and a reinforced concrete beam in a building or the like.
一般に建築物などにおいて、鉄筋コンクリート
（以下RCと称する）製の柱にRCの梁を接合する
場合、第２図に示すように、柱１の中に梁２の鉄
筋４を所定長さＬ以上固着し、ついでコンクリー
ト５を柱梁一体に打設する工法をとつている。
Generally, when joining an RC beam to a column made of reinforced concrete (hereinafter referred to as RC) in buildings, etc., as shown in Figure 2, the reinforcing bar 4 of the beam 2 is fixed in the column 1 for a predetermined length L or more. The method of construction is then to pour concrete 5 into the pillars and beams.
また鋼管コンクリート柱に梁を接合する場合
は、第３図に示す実開昭55−150103号公報に開示

６とを貫通する鉄筋１０を配設し、ついでコンク
リート５を打設することによつて梁１１と柱６を
接合する工法をとつている。 When joining a beam to a steel pipe concrete column, a bracket 7 is fixed to the column 6, and a steel pipe is attached to this bracket 7, as shown in the example disclosed in Japanese Utility Model Application Publication No. 150103/1983 shown in Fig. 3. A U-shaped steel 8 shaped into a U-shape is placed, the bracket 7 and the U-shaped steel 8 are connected by a batten 9, reinforcing bars 10 are placed to pass through the U-shaped steel 8 and the column 6, and then concrete 5 is placed. A construction method is used in which the beam 11 and the column 6 are connected by pouring.
なお鋼管コンクリート柱の鋼管と鋼管内に充填
したコンクリートとの付着力を増大させるため、
第４図に示すように、鋼管内面には金具１３ａ〜
１３ｄを固着している。 In addition, in order to increase the adhesion between the steel pipe of the steel pipe concrete column and the concrete filled in the steel pipe,
As shown in FIG. 4, the inner surface of the steel pipe has metal fittings 13a to
13d is fixed.
ところでRCの柱にRCの梁を接合する上記接合
部の構造においては、柱に梁の鉄筋を固着し、型
枠工事を施工した上でコンクリート５を打設する
ので、工事に手間がかかり工期が長くなる欠点を
有している。
By the way, in the structure of the above-mentioned joint where an RC beam is joined to an RC column, the reinforcing bars of the beam are fixed to the column, the formwork is constructed, and then the concrete 5 is poured, so the construction is labor-intensive and the construction period is shortened. It has the disadvantage of being long.
また鋼管コンクリート柱６に梁１１を接合する
構造においては、梁の鉄筋１０を柱に貫通させる
のはたしかに優れた手段ではあるが、鋼板で形成
したＵ型鋼８にコンクリートを打設する構造は、

び目板９により柱の鋼管に固着して応力を伝達す
るという複雑な構造となつている。それにブラケ
ツト７や目板９が柱６や梁１１の外側に露出し、
外観を損なうのも問題である。 Furthermore, in a structure in which a beam 11 is joined to a steel pipe concrete column 6, it is certainly an excellent method to have the reinforcing bar 10 of the beam penetrate the column, but in a structure in which concrete is poured into a U-shaped steel 8 formed of a steel plate,
Since almost no adhesion force between the beam concrete and the column can be expected, the U-shaped steel 8 is fixed to the column steel pipe by the bracket 7 and battens 9 to transmit stress, resulting in a complicated structure. In addition, the brackets 7 and battens 9 are exposed on the outside of the columns 6 and beams 11,
Another problem is that it spoils the appearance.
また鋼管と鋼管内に充填されたコンクリートと
の付着力を増加させるための金具１３ａ〜１３ｄ
は、この鋼管内面への固着に手間がかかるだけで
なく、コンクリートの充填の際コンクリートの流
れを阻害する欠点がある。 Also, metal fittings 13a to 13d for increasing the adhesion force between the steel pipe and the concrete filled in the steel pipe.
Not only does it take a lot of time to fix it to the inner surface of the steel pipe, but it also has the disadvantage that it obstructs the flow of concrete when it is filled with concrete.
本考案は従来技術による柱と梁との接合部構造
の上記問題点を解消するためになされたもので、
工法が簡単で強度上の信頼性の高い鋼管コンクリ
ート柱と鉄筋コンクリート梁との接合部構造を提
供しようとするものである。 The present invention was made in order to solve the above-mentioned problems of the conventional column-beam joint structure.
The present invention aims to provide a joint structure between a steel pipe concrete column and a reinforced concrete beam that is simple in construction and has high reliability in terms of strength.
上記目的を達成するため、本考案は建築物など

In order to achieve the above object, the present invention uses concrete-filled steel pipes or steel pipes with internal protrusions, which have protrusions on the outer surface where they join with beams, for columns in buildings, etc. A part of the reinforcing bars of the beam is placed through the column at the joint, and at the joint between the beam and the column, a plurality of reinforcing bars are placed around the outer periphery of the column in the direction of the column. Concrete was poured to cover the columns and reinforcing bars.

に伝達することを可能ならしめている。
The protrusions on the outer surface of the columns significantly increase the adhesion between the beam concrete and the columns. In addition, installing beam reinforcing bars that pass through columns at joints restrains the covering concrete and increases the adhesion between the columns and beams, compensating for the decrease in column strength caused by drilling holes, and This makes it possible to sufficiently transmit the load applied to the column to the column with a simple structure.
さらに内面突起付鋼管の使用により、鋼管柱と
充填コンクリートとの付着力は大きく増大し、鋼
管内面に金具を取り付ける手間を省略するととも
に、コンクリートの充填性を向上させている。 Furthermore, by using a steel pipe with internal projections, the adhesion between the steel pipe column and the concrete filling is greatly increased, eliminating the need to attach metal fittings to the inner surface of the steel pipe, and improving the filling properties of the concrete.

る。 As shown in the figure, a concrete-filled steel pipe with internal protrusions is used for the column 21, and the beam 23 of the column 21 is
A protrusion 22 is formed on the outer surface of the joint portion.
In addition, the reinforcing bars 24 of the beams are arranged to pass through the holes 26 drilled in the columns 21, and a plurality of covering reinforcing bars 27 are arranged in the column direction on the outer periphery of the columns 21 at the joints. 28 connects the covering reinforcing bars 27.

２７により十分補償される。 When concrete is poured at the joint between the column and beam arranged as described above, the protrusion 22 on the outer surface of the column 21
The beam concrete is firmly adhered to the column 21 by the beam reinforcement 24 penetrating the column 21, the covering reinforcement 27, etc., and the breaking strength between the column 21 and the beam 23 is dramatically improved. In addition, the strength of the column is reduced due to the hole 26 drilled in the column 21 to penetrate the reinforcing bar 24 of the beam.
The covering reinforcing bars 27 provided at the joints between the beams 22 and columns 21 provide sufficient compensation.
なお本実施例における柱２１外面の突起２２の
代わりに、柱２１外面にスタツド、ジベルなどを
固着してもよい。 Note that instead of the protrusion 22 on the outer surface of the column 21 in this embodiment, a stud, a dowel, etc. may be fixed to the outer surface of the column 21.

By placing concrete on the pillars and reinforcing bars to cover them, the adhesion between the pillars and beams at the joints between the pillars and beams was greatly increased.
The load on the beams can now be sufficiently transmitted to the columns.
