Description

本発明は、コンクリート製の梁部の端部と、コンクリート製の構造部（梁や柱や壁等）の側部とを、ピン連結してある梁のピン連結構造に関する。   The present invention relates to a pin connection structure of a beam in which an end portion of a concrete beam portion and a side portion of a concrete structure portion (beam, column, wall, etc.) are pin-connected.

従来、梁のピン連結構造としては、コンクリート製の梁部の端部に、連結用鉄骨部材の一部を突出させて埋設しておき、その突出端部を、鉄骨の構造部（例えばＩ形鋼）に予め位置決めして一体化されたガセットプレート（フランジとウェブとにわたって位置決めされて溶接によって一体化してあるプレート）に対してボルト連結することで、ピン連結部を構成してあるものがあった（例えば、特許文献１参照）。
即ち、梁部と構造部との連結箇所は、鉄骨構造によって構成してあった。 Conventionally, as a pin connection structure of a beam, a part of a connecting steel member protrudes and is embedded in an end portion of a concrete beam portion, and the protruding end portion is connected to a steel structure portion (for example, I-shaped). Some pin connections are configured by bolt connection to a gusset plate (plate that is positioned over the flange and web and integrated by welding) that is pre-positioned and integrated with the steel). (For example, see Patent Document 1).
That is, the connection part of a beam part and a structure part was comprised by the steel frame structure.

特開平８−６８１１３号公報（図２）JP-A-8-68113 (FIG. 2)

上述した従来の梁のピン連結構造によれば、梁部と構造部との連結の前に、構造部の梁取付対象部に、ガセットプレートを位置決めして溶接で固着しておく必要がある。
ガセットプレートの固着においては、予め、構造部に対して精度良く位置決めして作業を実施する必要があり、梁と構造部とのピン連結構造を形成するのに手間がかかる問題点があった。
また、構造部に対して梁部が斜めとなるような連結構造においては、ガセットプレートも梁部の長手方向に沿うように、構造部に対して斜めに取り付ける必要があり、位置決めや固着に、より多くの手間がかかることになる。 According to the above-described conventional pin connection structure of a beam, it is necessary to position and fix the gusset plate to the beam mounting target portion of the structure portion by welding before the connection between the beam portion and the structure portion.
In the fixing of the gusset plate, it is necessary to carry out the operation by accurately positioning in advance with respect to the structure portion, and there is a problem that it takes time to form a pin connection structure between the beam and the structure portion.
In addition, in the connection structure in which the beam part is inclined with respect to the structure part, the gusset plate also needs to be attached to the structure part obliquely along the longitudinal direction of the beam part. It will take more work.

従って、本発明の目的は、上記問題点を解消し、梁と構造部とのピン連結構造を形成するのに手間を掛けずに簡単に実施できる梁のピン連結構造を提供するところにある。   Accordingly, an object of the present invention is to provide a beam pin connection structure that can solve the above-described problems and can be easily implemented without taking time and effort to form a pin connection structure between the beam and the structure portion.

本発明の第１の特徴構成は、コンクリート製の梁部の端部と、コンクリート製の構造部の側部とを、ピン連結してある梁のピン連結構造であって、前記梁部の端部に埋設されて付着力を確保する梁部埋設部と、前記構造部に埋設さて付着力を確保する構造部埋設部と、前記梁部埋設部と前記構造部埋設部との間に介在して前記梁部と前記構造部との間でせん断力を伝達する介在部とを備えたピン連結部材を、前記梁部と前記構造部とにわたって埋設してあるところにある。   A first characteristic configuration of the present invention is a beam pin connection structure in which an end portion of a concrete beam portion and a side portion of a concrete structure portion are pin-connected, and the end of the beam portion Embedded between the beam embedded portion and the structural portion embedded portion, the beam embedded portion and the structural portion embedded portion embedded in the structural portion to secure the adhesive force. A pin connecting member having an intervening portion for transmitting a shearing force between the beam portion and the structure portion is embedded between the beam portion and the structure portion.

本発明の第１の特徴構成によれば、ピン連結部材を、梁部と構造部とにわたって埋設してあるから、梁部に対しては、ピン連結部材の梁部埋設部によって付着力が確保され、構造部に対しては、ピン連結部材の構造部埋設部によって付着力が確保され、安定した状態に埋設することができる。
そして、梁部と構造部との間に作用するせん断力は、介在部において伝達することができるから、梁部の重量を介在部を介して構造部に支持させることができる。一方、梁部と連結部との間に作用する曲げ力に対しては、介在部の変形によって吸収し、梁部と構造部との連結部を、実質的にピン連結構造とすることができる。
また、ピン連結部材を、梁部と構造部とにわたってコンクリート中に埋設するだけの手間で、梁部と構造部とのピン連結構造を形成することができるから、作業そのものが簡単な上、ピン連結部材の埋設設置対象は、コンクリートであるから、従来のように、ガセットプレートを芯材の決められた位置に高い精度で位置決めして溶接する等の必要が無く、より効率よくピン連結構造を形成することができる。よって、例えば、構造部に対して梁部を斜めに連結するような連結構造を形成する場合でも、ピン連結部材を構造部と梁部とにわたる状態にさえ配置すればよく、特に、大きな手間を掛けることなくピン連結構造を形成することができる。
更には、構造部の芯材（例えば、Ｉ形鋼）に溶接の熱歪みを残す虞もない。
以上の結果、構造部と梁部とのピン連結構造を、手間を掛けずに簡単に形成できるようになる。 According to the first characteristic configuration of the present invention, since the pin connecting member is embedded across the beam portion and the structural portion, the adhesion force is secured to the beam portion by the beam embedded portion of the pin connecting member. In addition, the adhesive force is secured to the structure portion by the structure portion embedded portion of the pin connecting member, and the structure portion can be embedded in a stable state.
And since the shear force which acts between a beam part and a structure part can be transmitted in an interposition part, the weight of a beam part can be supported on a structure part via an interposition part. On the other hand, the bending force acting between the beam part and the connection part is absorbed by the deformation of the interposition part, and the connection part between the beam part and the structure part can be substantially made into a pin connection structure. .
In addition, since the pin connection structure between the beam portion and the structure portion can be formed by simply burying the pin connection member between the beam portion and the structure portion in the concrete, the work itself is simple and the pin Since the object to embed and install the connecting member is concrete, there is no need to position and weld the gusset plate at a predetermined position of the core material with high accuracy as in the past, and a more efficient pin connection structure can be achieved. Can be formed. Therefore, for example, even in the case of forming a connection structure in which the beam part is obliquely connected to the structure part, the pin connection member only needs to be arranged in a state extending between the structure part and the beam part. A pin connection structure can be formed without hanging.
Furthermore, there is no possibility of leaving a thermal distortion of welding in the core material (for example, I-shaped steel) of the structure portion.
As a result, the pin connection structure between the structure portion and the beam portion can be easily formed without taking time and effort.

本発明の第２の特徴構成は、前記ピン連結部材は、一枚の金属板で構成してあり、前記一枚の金属板は、その厚み方向が前記梁部の幅方向に沿う姿勢で埋設してあり、前記梁部埋設部と前記構造部埋設部とには、その厚み方向に沿って突出する状態に複数のスタッドが設けてあるところにある。   According to a second characteristic configuration of the present invention, the pin connecting member is formed of a single metal plate, and the single metal plate is embedded in a posture in which the thickness direction is along the width direction of the beam portion. In addition, the beam portion embedded portion and the structure portion embedded portion are provided with a plurality of studs so as to protrude along the thickness direction.

本発明の第２の特徴構成によれば、ピン連結部材として、厚み方向が梁部の幅方向に沿う姿勢に配置した一枚の金属板であるから、上面視において場所を取らず、構造部及び梁部に埋設する上で、それぞれの鉄筋や芯材等との干渉を避け易く、設置性に富んでいるい。また、ピン連結部材を構成する金属板は、縦長断面によって必要な断面積を確保でき、梁部と構造部との間のせん断力を支持することができる。   According to the second characteristic configuration of the present invention, the pin connecting member is a single metal plate arranged in a posture in which the thickness direction is along the width direction of the beam portion. In addition, it is easy to avoid interference with each reinforcing bar, core material, etc. when embeding in the beam part, and it is easy to install. Moreover, the metal plate which comprises a pin connection member can ensure a required cross-sectional area by a longitudinally long cross section, and can support the shear force between a beam part and a structure part.

本発明の第３の特徴構成は、前記梁部と前記構造部との突合せ面間には、互いの相対変位を許容自在な緩衝層が介在させてあるところにある。   A third characteristic configuration of the present invention is that a buffer layer capable of allowing relative displacement between each other is interposed between the butting surfaces of the beam portion and the structure portion.

本発明の第３の特徴構成によれば、緩衝層によって、梁部と構造部との相対変位を許容できる。
従って、例えば、構造部に対して梁部が上下に揺動するような連結部での曲げ変形が生じても、その動きを緩衝層によって許容でき、より好ましい状態のピン連結構造を構築することができる。
その結果、連結部での曲げ変形によって、構造部と梁部との突合せ面どうしが直接に押し当たって支圧破壊を生じたり、梁の曲げモーメントが柱に伝達されて柱の曲げ応力が増加するといった現象をより確実に防止できるようになる。 According to the third characteristic configuration of the present invention, the buffer layer can allow relative displacement between the beam portion and the structure portion.
Therefore, for example, even if bending deformation occurs in the connecting portion where the beam portion swings up and down with respect to the structural portion, the movement can be allowed by the buffer layer, and a more preferable pin connecting structure is constructed. Can do.
As a result, due to the bending deformation at the connecting part, the abutment surfaces of the structural part and the beam part directly press against each other to cause bearing failure, or the bending moment of the beam is transmitted to the column and the bending stress of the column increases. It becomes possible to prevent the phenomenon such as that more reliably.

以下に本発明の実施の形態を図面に基づいて説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図１、図２は、構造部１の一例である梁１Ａの側部に対して、連結梁（梁部の一例）２の端部をピン連結してある『梁のピン連結構造』を示している。   1 and 2 show a “beam pin connection structure” in which the end of a connecting beam (an example of a beam portion) 2 is pin-connected to a side portion of a beam 1A which is an example of a structure portion 1. ing.

梁１Ａは、鉄筋コンクリート製であり、その両端部を一対の柱（不図示）に各別に剛接合してラーメン構造が形成されている。
梁１Ａは、図３に示すように、横断面形状が矩形形状となるように形成してあり、断面内には、梁長手方向に沿って配置された複数の主筋３と、それを取り囲む状態に配置された複数のあばら筋４とを備えて構成されている。 The beam 1A is made of reinforced concrete, and a rigid frame structure is formed by rigidly joining both ends thereof to a pair of columns (not shown).
As shown in FIG. 3, the beam 1 </ b> A is formed so that the cross-sectional shape is a rectangular shape, and in the cross-section, a plurality of main bars 3 arranged along the beam longitudinal direction and a state surrounding the main bars 3 And a plurality of stirrups 4 arranged on the surface.

主筋３は、矩形断面の上辺部と、下辺部とにおいて、梁の幅方向に間隔をあけて配置されている。   The main bars 3 are arranged at intervals in the width direction of the beam at the upper side and the lower side of the rectangular cross section.

あばら筋４は、主筋３を取り囲む矩形形状に形成してあり、梁の長手方向に間隔をあけて配置されている。
尚、前記主筋３やあばら筋４の外方には、コンクリートＣの所定の鉄筋かぶりが確保されている。 The streaks 4 are formed in a rectangular shape surrounding the main bars 3, and are arranged at intervals in the longitudinal direction of the beam.
It should be noted that a predetermined rebar cover of the concrete C is secured outside the main bars 3 and the ribs 4.

連結梁２は、基本断面構造は、梁１Ａと同様で、図４に示すように、複数の主筋５とあばら筋６とを備えて構成されている。
但し、連結梁２は、平面視において、図１に示すように、梁１Ａの軸芯Ｓに対して鋭角の交差角度θとなる配置で連結されるから、連結梁２の端面部２ａは、梁１Ａの側面１ａに沿うように、連結梁２の軸芯Ｔに対して前記交差角度θと同じ角度で傾斜させてある。 The connecting beam 2 has a basic cross-sectional structure similar to that of the beam 1A, and includes a plurality of main bars 5 and ribs 6 as shown in FIG.
However, since the connecting beam 2 is connected in an arrangement having an acute crossing angle θ with respect to the axis S of the beam 1A in a plan view, the end surface portion 2a of the connecting beam 2 is It is inclined at the same angle as the crossing angle θ with respect to the axis T of the connecting beam 2 along the side surface 1a of the beam 1A.

あばら筋６は、連結梁２の端部側では、端面部２ａに沿う状態で複数列設けてあり、それらから連結梁中央側に隣接するあばら筋６どうしは、徐々に連結梁２の幅方向に沿うように姿勢を変えて配置してある。   The stirrups 6 are provided in a plurality of rows on the end side of the connecting beam 2 along the end surface 2a, and the stirrups 6 adjacent to the connecting beam center side gradually extend from each other in the width direction of the connecting beam 2. The posture is changed so as to follow.

また、梁１Ａと連結梁２とにわたって、一枚の金属板で構成されたピン連結部材７が埋設してある。   A pin connecting member 7 made of a single metal plate is embedded between the beam 1A and the connecting beam 2.

ピン連結部材７は、図１、図２に示すように、側面視において横長の長方形の一枚の金属板７Ａで構成してあり、連結梁２の端部に埋設されて付着力を確保する連結梁埋設部（梁部埋設部に相当）７ｂと、前記梁１Ａに埋設されて付着力を確保する梁埋設部（構造部埋設部に相当）７ａと、連結梁埋設部７ｂと梁埋設部７ａとの間に介在して連結梁２と梁１Ａとの間でせん断力を伝達する介在部７ｃとを設けて構成してある。   As shown in FIGS. 1 and 2, the pin connecting member 7 is composed of a single rectangular metal plate 7 </ b> A that is horizontally long when viewed from the side, and is embedded in the end portion of the connecting beam 2 to ensure adhesion. Connecting beam embedded portion (corresponding to the beam portion embedded portion) 7b, a beam embedded portion (corresponding to the structure portion embedded portion) 7a that is embedded in the beam 1A to ensure adhesion, the connecting beam embedded portion 7b, and the beam embedded portion An intervening portion 7c that is interposed between the connecting beam 2 and the beam 1A is provided between the connecting beam 2 and the beam 1A.

前記一枚の金属板７Ａは、その厚み方向が連結梁２の幅方向に沿う姿勢で埋設してあり、連結梁埋設部７ｂと梁埋設部７ａとには、その厚み方向に沿って突出する状態に複数のスタッド８が設けてあり（図５参照）、コンクリートＣへのアンカー効果を発揮できるように構成されている。   The single metal plate 7A is embedded in such a manner that the thickness direction thereof is along the width direction of the connecting beam 2, and the connecting beam embedded portion 7b and the beam embedded portion 7a protrude along the thickness direction. A plurality of studs 8 are provided in the state (refer to FIG. 5), and the anchor effect to the concrete C can be exhibited.

従って、梁埋設部７ａは、梁１Ａのあばら筋４どうしの間から梁１Ａの断面中央側に挿入された状態で設置され、連結梁埋設部７ｂは、連結梁２の端面部２ａから連結梁２の軸芯Ｔに沿って連結梁２の長手方向中央側に挿入された状態で設置されている。   Accordingly, the beam embedded portion 7a is installed in a state where the beam embedded portion 7a is inserted between the ribs 4 of the beam 1A to the center of the cross section of the beam 1A, and the connecting beam embedded portion 7b is connected to the connecting beam 2 from the end surface portion 2a. It is installed in the state inserted along the longitudinal direction center side of the connecting beam 2 along the axial center T of 2.

また、連結梁２の端面部２ａと、梁１Ａの側面１ａとの間には、例えば、スタイロフォーム等のシート材で構成された緩衝層９が介在させてある。   Further, a buffer layer 9 made of a sheet material such as styrofoam is interposed between the end surface portion 2a of the connecting beam 2 and the side surface 1a of the beam 1A.

以上の構成により、梁１Ａと連続梁２とは、前記介在部７ｃの変形が許容された状態で連結され、実質的に、ピン連結構造として機能する。従って、連続梁２の端部を梁１Ａによって回転自在に支持することができ、連続梁２の曲げモーメントの全てが梁１Ａに伝達することを防止できる。その結果、梁１Ａの剛性を、最小限度に止めた部材設計が可能となる。   With the above configuration, the beam 1A and the continuous beam 2 are connected in a state where the deformation of the interposition part 7c is allowed, and substantially function as a pin connection structure. Therefore, the end portion of the continuous beam 2 can be rotatably supported by the beam 1A, and all of the bending moment of the continuous beam 2 can be prevented from being transmitted to the beam 1A. As a result, it is possible to design a member that minimizes the rigidity of the beam 1A.

次に、梁１Ａと連結梁２とのピン連結手順の一例について説明する。
［１］梁１Ａと、連結梁２との一連の型枠Ｋを組み上げる（図６参照）。
［２］梁１Ａの型枠Ｋ１内に、主筋３とあばら筋４とを組むと共に、連結梁２の型枠Ｋ２内に、主筋５とあばら筋６とを組む（図７参照）。
［３］型枠Ｋにおける梁空間Ｖ１と連結梁空間Ｖ２との境界に、緩衝層９を固定する。
［４］緩衝層９の幅中央部に、ピン連結部材７の介在部７ｃを挿入自在な切り込み９ａを入れた状態で、その切り込み９ａに介在部７ｃを挿入しながら、ピン連結部材７を、梁空間Ｖ１と連結梁空間Ｖ２とにわたって配置する。ピン連結部材７の仮固定は、主筋３，５や、あばら筋４，６に鉄筋棒等の添え材を介在させて溶接や結束線によって固定することで実施できる。
［５］梁空間Ｖ１と連結梁空間Ｖ２とに、それぞれコンクリートＣを打設する（図８参照）。両空間Ｖ１，Ｖ２へのコンクリート打設速度は、いずれの空間においても打設深度がほぼ同じとなるように設定することで、両空間Ｖ１，Ｖ２でのコンクリート圧の均衡を保つことができ、緩衝層９が何れかの空間に変位することを防止できる。よって、別途型枠を設置しなくても、緩衝層９によって両空間Ｖ１，Ｖ２の区画ができる。
［６］コンクリートの所定の養生期間の経過後、脱型する（図９参照）。 Next, an example of a pin connection procedure between the beam 1A and the connection beam 2 will be described.
[1] A series of formwork K of the beam 1A and the connecting beam 2 is assembled (see FIG. 6).
[2] The main reinforcement 3 and the stirrup 4 are assembled in the formwork K1 of the beam 1A, and the main reinforcement 5 and the stirrup 6 are assembled in the formwork K2 of the connecting beam 2 (see FIG. 7).
[3] The buffer layer 9 is fixed to the boundary between the beam space V1 and the connection beam space V2 in the formwork K.
[4] With the notch 9a into which the interposition part 7c of the pin coupling member 7 can be freely inserted in the central part of the width of the buffer layer 9, the pin coupling member 7 is inserted while inserting the interposition part 7c into the notch 9a. It arrange | positions over the beam space V1 and the connection beam space V2. Temporary fixing of the pin connecting member 7 can be performed by interposing an accessory such as a reinforcing bar to the main bars 3 and 5 and the ribs 4 and 6 and fixing them by welding or binding wires.
[5] Concrete C is placed in each of the beam space V1 and the connecting beam space V2 (see FIG. 8). By setting the concrete placement speed to both spaces V1, V2 so that the placement depth is almost the same in any space, the concrete pressure balance in both spaces V1, V2 can be maintained, It is possible to prevent the buffer layer 9 from being displaced into any space. Therefore, both spaces V1 and V2 can be partitioned by the buffer layer 9 without installing a separate formwork.
[6] After a predetermined curing period of concrete, the mold is removed (see FIG. 9).

当該実施形態の梁のピン連結構造によれば、連結梁２からのせん断力をピン連結部材７の介在部７Ｃを介して梁１Ａに支持させることができながら、梁１Ａと連結梁２との間に作用する曲げ力に対しては、介在部の変形によって吸収し、梁１Ａと連結梁２とを、実質的にピン連結することができる。
また、ピン連結部材７となる一枚の金属板７Ａを、梁１Ａと連結梁２とにわたってコンクリートＣ中に埋設するだけの手間で、ピン連結構造を簡単に形成することができる。
そして、一枚の金属板７Ａの埋設設置対象は、コンクリートＣであるから、埋設位置の融通性がよく、現場作業をより効率的に実施できる。
また、梁１Ａと連結梁２との間には、緩衝層９を設けてあるから、両者の動きを、緩衝層９で無理なく受け止めることができ、ピン連結部としての動きをスムースに許容することができる。 According to the pin connection structure of the beam of this embodiment, the shearing force from the connection beam 2 can be supported by the beam 1A via the interposition part 7C of the pin connection member 7, while the beam 1A and the connection beam 2 are The bending force acting between them is absorbed by the deformation of the interposition part, and the beam 1A and the connecting beam 2 can be substantially pin-connected.
In addition, the pin connection structure can be easily formed by simply embedding one metal plate 7A to be the pin connection member 7 in the concrete C across the beam 1A and the connection beam 2.
And since the embedding installation object of the metal plate 7A of one sheet is concrete C, the flexibility of an embedding position is good and field work can be implemented more efficiently.
In addition, since the buffer layer 9 is provided between the beam 1A and the connecting beam 2, the movement of both can be reasonably received by the buffer layer 9, and the movement as the pin connecting portion is allowed smoothly. be able to.
