Description

本発明は、柱と梁とが交差接合される柱梁接合部が補強された鉄筋構造に関する。   The present invention relates to a reinforcing bar structure in which a column beam joint where a column and a beam are cross-joined is reinforced.

一般に、柱や梁に鉄筋が使用される鉄筋構造においては、柱と梁とが交差接合される柱梁接合部は、柱に配筋される柱用主筋と、梁に配筋される梁用主筋とが連結され、さらにこの部分にせん断補強筋が配筋される。   In general, in a reinforcing bar structure in which reinforcing bars are used for columns and beams, the column-beam joint where the columns and beams are cross-joined is the main bars for the columns that are arranged in the columns and the beams that are arranged in the beams. The main reinforcement is connected, and a shear reinforcement is arranged in this part.

この柱梁接合部には、柱の軸力が作用する他、柱及び梁に荷重が繰り返し加えられることで、柱における柱梁接合部の上下に当たる部分に力が加わり、鉄筋構造に打設されるコンクリートにひび割れが発生して柱の強度を低下させる恐れがある。特に、地震時においては、柱の変位に比べて梁の変位が多く、この梁の変位により柱に対して上下方向(柱に対して垂直方向)の大きな力が加えられると、柱において梁の上下両側に当たる部分（すなわち、柱における柱梁接合部の上下両側の部分）にひび割れが発生する。このようなひび割れなどを防止するために、柱梁接合部を補強する必要がある。   In addition to the axial force of the column acting on the beam-column joint, a load is repeatedly applied to the column and beam, so that a force is applied to the upper and lower portions of the beam-column joint in the column, and the beam is placed in the reinforcing bar structure. There is a risk that the concrete will crack and reduce the strength of the column. In particular, during an earthquake, the displacement of the beam is greater than the displacement of the column, and if a large force in the vertical direction (perpendicular to the column) is applied to the column due to the displacement of the beam, Cracks occur in the portions that hit both the upper and lower sides (that is, the portions on the upper and lower sides of the column-beam joint in the column). In order to prevent such cracks and the like, it is necessary to reinforce the beam-column joint.

従来、柱用主筋を備える柱と、梁用主筋を備える梁とが接合した鉄筋構造が知られている（特許文献１）。
特許文献１で示される鉄筋構造では、柱梁接合部の上端部及び下端部におけるひび割れの進展を抑制するために、柱用主筋を囲む補強バンドが設けられている。 2. Description of the Related Art Conventionally, a reinforcing bar structure in which a column including a column main bar and a beam including a beam main bar are joined is known (Patent Document 1).
In the reinforcing bar structure shown in Patent Document 1, a reinforcing band that surrounds the column main bar is provided in order to suppress the progress of cracks at the upper end and the lower end of the beam-column joint.

特開２０１０−２３６２１７号公報JP 2010-236217 A

しかし、特許文献１に記載のような従来の鉄筋構造では、補強バンドが柱梁接合部の上下端に設けられているため、補強バンドが梁用主筋に隣接することになり、補強バンドを設けるときの作業性が考慮されていない。
また、補強バンドが柱梁接合部の上下端に設けられているため、柱に加わるせん断応力に対して柱の補強が必ずしも十分とはいえず、また、より大きな柱の補強も求められている。 However, in the conventional reinforcing bar structure as described in Patent Document 1, since the reinforcing bands are provided at the upper and lower ends of the column beam joint, the reinforcing band is adjacent to the beam main bar, and the reinforcing band is provided. When workability is not considered.
In addition, since the reinforcing bands are provided at the upper and lower ends of the column-beam joint, it is not always sufficient to reinforce the column against the shear stress applied to the column, and a larger column is also required to be reinforced. .

本発明の目的は、補強部材を設けるときの作業性がよく、また、せん断応力に対して柱の補強を十分に行うことができる鉄筋構造を提供することである。   An object of the present invention is to provide a reinforcing bar structure that has good workability when a reinforcing member is provided and can sufficiently reinforce a column against shear stress.

本発明の鉄筋構造は、鉛直方向に延びて配筋された複数の柱用主筋及び前記柱用主筋の軸方向と交差する平面内において前記柱用主筋を囲んで配筋された複数の柱用せん断補強筋を備える柱と、水平方向に延びて配筋された複数の梁用主筋を備える梁とが接合した鉄筋構造であって、前記柱の前記梁と接合した柱梁接合部において、前記柱用主筋を囲んで拘束する閉鎖型の補強部材が設けられ、前記補強部材は、前記柱用主筋の軸方向における幅寸法が、前記柱用主筋の軸方向における前記柱用せん断補強筋の幅寸法よりも大きく、かつ、前記柱用主筋の軸方向において、前記柱梁接合部の上端と下端とにそれぞれ離隔していることを特徴とする。   The reinforcing bar structure according to the present invention is for a plurality of column main bars that are arranged extending in the vertical direction and that surround the column main bars in a plane that intersects the axial direction of the column main bars. In a reinforcing bar structure in which a column including a shear reinforcement bar and a beam including a plurality of beam main bars extending in the horizontal direction are joined to each other, the column beam joint part joined to the beam of the column, A closed-type reinforcing member that surrounds and restrains the column main reinforcing bar is provided, and the reinforcing member has a width dimension in the axial direction of the column main reinforcing bar that is the width of the column shear reinforcing bar in the axial direction of the column main reinforcing bar. It is larger than the dimension, and is spaced apart from the upper end and the lower end of the column beam joint in the axial direction of the column main reinforcement.

この構成の本発明では、補強部材は、柱用主筋の軸方向において、柱梁接合部の上端と下端とにそれぞれ離隔しているため、補強部材が梁用主筋から離れ、補強部材を設けるときの作業性がよい。また、柱に加わるせん断応力は柱梁接合部の中央に最も大きく作用する。よって、せん断応力が最も大きく作用する部分を補強部材によって補強でき、せん断応力に対して柱の補強を十分に行うことができる。   In the present invention with this configuration, the reinforcing member is spaced apart from the upper end and the lower end of the column beam joint in the axial direction of the column main reinforcement. Good workability. In addition, the shear stress applied to the column is the largest at the center of the column beam joint. Therefore, the portion where the shear stress acts most greatly can be reinforced by the reinforcing member, and the column can be sufficiently reinforced against the shear stress.

本発明では、前記補強部材は、外枠と、前記外枠の内面を連結して前記外枠の内部を仕切る仕切り部とを備える構成が好ましい。
この構成の本発明では、補強部材は、外枠と、外枠の内面を連結して外枠の内部を仕切る仕切り部とを備えるため、外枠が仕切り部によって補強される。このため、仕切り部によって補強された外枠と、仕切り部とで柱用主筋を囲むので、せん断応力に対して柱の補強をより向上できる。 In the present invention, it is preferable that the reinforcing member includes an outer frame and a partition portion that connects an inner surface of the outer frame and partitions the inside of the outer frame.
In the present invention having this configuration, the reinforcing member includes an outer frame and a partition portion that connects the inner surface of the outer frame and partitions the inside of the outer frame, and thus the outer frame is reinforced by the partition portion. For this reason, since the column main reinforcement is surrounded by the outer frame reinforced by the partition portion and the partition portion, the reinforcement of the column can be further improved against the shear stress.

本発明では、前記補強部材は、帯状部材の端部どうしを突き合わせて溶接で接合した閉じた枠形状である構成が好ましい。
この構成の本発明では、補強部材は、帯状部材の端部どうしを突き合わせて溶接で接合した閉じた枠形状であるため、補強部材が全体として強固となり、せん断応力に対して柱の補強をより向上できる。また、補強部材全体を大きな強度とすることが溶接でできるので、強度を容易に向上させることができる。 In the present invention, it is preferable that the reinforcing member has a closed frame shape in which end portions of the band-shaped member are butted and joined by welding.
In the present invention having this configuration, the reinforcing member has a closed frame shape in which the end portions of the band-shaped member are butted and joined by welding, so that the reinforcing member is strengthened as a whole, and the column is further reinforced against shear stress. It can be improved. In addition, since the entire reinforcing member can be made strong by welding, the strength can be easily improved.

図１及び図２に示すように、建物は、複数の柱２と、柱２と接合する複数の梁３とを備えた複数階建ての鉄筋コンクリート造りであり、鉄筋構造１にコンクリートＣが打設されている。
柱２と梁３との接合形態としては、十字形接合Ｓ１、ト形接合Ｓ２、Ｌ形接合Ｓ３やＴ形接合Ｓ４があり、本実施形態は、これらの接合Ｓ１〜Ｓ４の柱梁接合部に適用される。以下では、十字形接合Ｓ１を例にとって説明する。 As shown in FIGS. 1 and 2, the building is a multi-storey reinforced concrete structure including a plurality of columns 2 and a plurality of beams 3 joined to the columns 2, and concrete C is placed on the reinforced structure 1. Has been.
As the joining form of the column 2 and the beam 3, there are a cross-shaped joint S1, a to-shaped joint S2, an L-shaped joint S3, and a T-shaped joint S4. Applies to In the following description, the cruciform joint S1 will be described as an example.

柱２を構成する鉄筋構造は、鉛直方向に延びて等間隔に配筋された複数の柱用主筋２１と、柱用主筋２１の軸方向と交差する平面（図２における紙面と垂直な平面）内において柱用主筋２１を囲んで等間隔に配筋されて柱２のせん断強度を補強する複数の柱用せん断補強筋２２とを備える。
柱用せん断補強筋２２は、柱用主筋２１の軸方向における所定の幅寸法Ｔ１を有する。幅寸法Ｔ１は梁せいＴ０の約１／７０となっている（Ｔ１≒Ｔ０／７０）。ただし、後述する柱梁接合部２００の中央、すなわち後述する補強部材１０Ａが設けられる位置には、柱用せん断補強筋２２は設けられていない。 The reinforcing bar structure that constitutes the column 2 includes a plurality of column reinforcing bars 21 that extend in the vertical direction and are arranged at equal intervals, and a plane that intersects the axial direction of the column reinforcing bars 21 (a plane perpendicular to the paper surface in FIG. 2). A plurality of column shear reinforcement bars 22 are provided which surround the column main bars 21 and are arranged at equal intervals to reinforce the shear strength of the columns 2.
The column shear reinforcing bar 22 has a predetermined width T1 in the axial direction of the column main bar 21. The width T1 is about 1/70 of the beam T0 (T1≈T0 / 70). However, the column shear reinforcing bar 22 is not provided at the center of the column beam joint portion 200 described later, that is, at a position where a reinforcement member 10A described later is provided.

梁３を構成する鉄筋構造は、水平方向に延びて所定間隔を空けて配筋された複数の梁用主筋３１と、梁用主筋３１の軸方向と交差する平面（図２における紙面と垂直な平面）内において梁用主筋３１を囲んで等間隔に梁用主筋３１の延出方向に配筋されて梁３のせん断強度を補強する複数の梁用せん断補強筋３２とを備える。ただし、後述する柱梁接合部２００の中央、すなわち後述する補強部材１０Ａが設けられる位置には、梁用せん断補強筋３２は設けられていない。
梁用主筋３１は、梁３の上端側に配筋される上部主筋３１Ａと、梁３の下端側に配筋される下部主筋３１Ｂとを備える。 The reinforcing bar structure constituting the beam 3 includes a plurality of beam main bars 31 extending in the horizontal direction and arranged at a predetermined interval, and a plane intersecting the axial direction of the beam main bars 31 (perpendicular to the paper surface in FIG. 2). A plurality of beam reinforcing bars 32 for reinforcing the shear strength of the beam 3, which are arranged in the extending direction of the beam main bar 31 at equal intervals so as to surround the beam main bar 31 in the plane). However, the beam shear reinforcing bar 32 is not provided in the center of the column beam joint portion 200 described later, that is, in a position where a reinforcing member 10A described later is provided.
The beam main bar 31 includes an upper main bar 31A arranged on the upper end side of the beam 3 and a lower main bar 31B arranged on the lower end side of the beam 3.

このような柱２と梁３とは、柱梁接合部２００で接合される。柱梁接合部２００は、柱せいと同じ長さ、梁せいＴ０と同じ長さ、そして柱２及び梁３の幅（図２における紙面と垂直な方向における柱及び梁の長さ）と同じ長さで囲まれた領域である。   Such columns 2 and beams 3 are joined by a column-beam joint portion 200. The column beam joint 200 has the same length as the column, the same length as the beam T0, and the same length as the width of the columns 2 and 3 (the length of the columns and beams in the direction perpendicular to the paper surface in FIG. 2). It is an area surrounded by

柱用主筋２１の軸方向において、柱梁接合部２００の上端と下端とにそれぞれ離隔して、複数の柱用主筋２１を囲んで拘束する閉鎖型の補強部材１０Ａが設けられる。
補強部材１０Ａは、ＳＳ４００などの一般構造用圧延鋼材や鉄といった金属製の板材や、あるいは繊維補強合成樹脂製の板材から形成され、枠形状の外枠１０１で構成される。 In the axial direction of the column main reinforcement 21, a closed type reinforcing member 10 </ b> A that surrounds and restrains the plurality of column main reinforcements 21 is provided separately from the upper end and the lower end of the column beam joint portion 200.
The reinforcing member 10A is made of a general structural rolled steel material such as SS400, a metal plate material such as iron, or a fiber reinforced synthetic resin plate material, and includes a frame-shaped outer frame 101.

外枠１０１は断面視四角形の枠であり、柱用主筋２１の軸方向における幅寸法Ｔ２は、梁せいＴ０の約１／４から１／２であり（Ｔ０／４≦Ｔ２≦Ｔ０／２）、柱用せん断補強筋２２の幅寸法Ｔ１よりも大きい（Ｔ２＞Ｔ１）。外枠１０１は、４つの角のうち少なくとも１つの角において溶接で接合されており、１つの閉じた枠となっている。外枠１０１は、例えば、帯状部材である帯状の鋼板を四角形に折り曲げて、始端と終端とを突き合わせて溶接で接合したり、あるいは帯状部材である４枚の短冊状の鋼板を四角形に組み立て、それぞれの端部どうしを突き合わせて溶接で接合することにより形成される。このような接合部分の強度は、補強部材１０Ａを構成する板材自体の強度（母材強度）と同じ、あるいは母材強度以上となる。   The outer frame 101 is a quadrangular frame in sectional view, and the width dimension T2 in the axial direction of the columnar main bar 21 is about 1/4 to 1/2 of the beam bar T0 (T0 / 4 ≦ T2 ≦ T0 / 2). It is larger than the width dimension T1 of the column shear reinforcement 22 (T2> T1). The outer frame 101 is joined by welding at at least one of the four corners to form one closed frame. The outer frame 101 is formed by, for example, bending a belt-shaped steel plate, which is a belt-shaped member, into a quadrangle, butting the start and end ends together by welding, or assembling four strip-shaped steel plates, which are belt-shaped members, into a quadrilateral, Each end is abutted and joined by welding. The strength of such a joining portion is the same as the strength (base material strength) of the plate material itself constituting the reinforcing member 10A, or is equal to or higher than the base material strength.

このような補強部材１０Ａは、上部主筋３１Ａ及び下部主筋３１Ｂから所定距離離れて柱用主筋２１の軸方向における中央に配筋され、補強部材１０Ａの内面は柱用主筋２１と当接する。これによって、補強部材１０Ａは柱用主筋２１を囲み、柱２に加わるせん断応力によって柱用主筋２１が変形することを防止する。   The reinforcing member 10 </ b> A is arranged at the center in the axial direction of the column main bar 21 at a predetermined distance from the upper main bar 31 </ b> A and the lower main bar 31 </ b> B, and the inner surface of the reinforcing member 10 </ b> A is in contact with the column main bar 21. Accordingly, the reinforcing member 10A surrounds the column main reinforcement 21 and prevents the column main reinforcement 21 from being deformed by the shearing stress applied to the column 2.

従って、本実施形態では、以下の作用効果を奏することができる。
（１）本実施形態の鉄筋構造１では、補強部材１０Ａは、柱用主筋２１の軸方向において、柱梁接合部２００の上端と下端とにそれぞれ離隔しているため、補強部材１０Ａが上部主筋３１Ａ及び下部主筋３１Ｂから離れ、補強部材１０Ａを設けるときの作業性がよい。また、柱２に加わるせん断応力は柱梁接合部２００の中央に最も大きく作用する。よって、せん断応力が最も大きく作用する部分を補強部材１０Ａによって補強でき、せん断応力に対して柱２の補強を十分に行うことができる。 Therefore, in this embodiment, the following effects can be obtained.
(1) In the reinforcing bar structure 1 of the present embodiment, the reinforcing member 10A is separated from the upper end and the lower end of the column beam joint portion 200 in the axial direction of the column main reinforcing bar 21, and therefore the reinforcing member 10A is the upper main reinforcing bar. Workability is improved when the reinforcing member 10A is provided apart from 31A and the lower main reinforcement 31B. Further, the shear stress applied to the column 2 acts most greatly at the center of the column beam joint portion 200. Therefore, the portion where the shear stress acts most greatly can be reinforced by the reinforcing member 10A, and the column 2 can be sufficiently reinforced against the shear stress.

（２）また、補強部材１０Ａは、帯状部材の端部どうしを突き合わせて溶接で接合した閉じた枠形状である。このため、補強部材１０Ａが全体として強固となり、せん断応力に対して柱２の補強をより向上できる。また、補強部材１０Ａ全体を大きな強度とすることが溶接でできるので、強度を容易に向上させることができる。 (2) Further, the reinforcing member 10A has a closed frame shape in which the end portions of the band-shaped member are abutted and joined by welding. For this reason, the reinforcing member 10A is strengthened as a whole, and the reinforcement of the column 2 can be further improved against the shear stress. Further, since the entire reinforcing member 10A can be made strong by welding, the strength can be easily improved.

＜第２実施形態＞
次に、本発明の第２実施形態について説明する。
図４は、本実施形態の補強部材１０Ｂを示す斜視図である。
図４に示すように、本実施形態では、第１実施形態と異なり、補強部材１０Ｂは、外枠１０１と、外枠１０１の内面どうしを連結して外枠１０１内部を仕切る仕切り部１０２とを備える。

The outer frame 101 is reinforced by the partition part 102. For this reason, since the column main reinforcement 21 is surrounded by the outer frame 101 reinforced by the partition portion 102 and the partition portion 102, the reinforcement of the column 2 can be further improved against shear stress.
