Description

本発明は、摩擦接合構造に関するものである。   The present invention relates to a friction bonding structure.

従来、梁、柱、筋違等の建築構造物の接続方法としては、高力ボルトを利用した摩擦接合が用いられている。   Conventionally, as a method for connecting a building structure such as a beam, a column, or a streak, friction bonding using a high-strength bolt has been used.

摩擦接合とは高力ボルトに軸力を導入して接合部材を締め付け、部材間に発生する摩擦力によって部材同士を接続する方法であり、以下のようなものが知られている。（特許文献１）。
特開平１０-１８４２３号公報 Friction welding is a method in which an axial force is introduced into a high-strength bolt to fasten a joining member, and the members are connected to each other by frictional force generated between the members. The following are known. (Patent Document 1).
Japanese Patent Laid-Open No. 10-18423

一方、摩擦接合では、摩擦力が接合部の摩擦係数とボルトの軸力に依存する。 しかしながら、建築構造物で使用される鋼材の摩擦接合面は、通常、赤錆面やショットブラスト面等とする処理がされるが、大きな摩擦係数を安定して得ることは困難で、摩擦係数は０．４５に設定されている。従って、大きな摩擦力を得ようとする場合、ボルトの軸力を大きくしなければならない。   On the other hand, in friction welding, the friction force depends on the friction coefficient of the joint and the axial force of the bolt. However, the friction joint surfaces of steel materials used in building structures are usually treated as red rust surfaces or shot blast surfaces, but it is difficult to stably obtain a large friction coefficient, and the friction coefficient is 0. .45 is set. Therefore, in order to obtain a large frictional force, the axial force of the bolt must be increased.

そのため、ボルトの本数を増やしたり、ボルトの径を大きくしたりしなくてはならず、接合部が大型化し、コストが高くなるという問題があった。   For this reason, the number of bolts must be increased or the diameter of the bolts must be increased, resulting in a problem that the joint becomes larger and the cost is increased.

本発明は、このような問題に鑑みてなされたもので、その目的は小型で低コストの摩擦接合構造を提供することにある。   The present invention has been made in view of such problems, and an object thereof is to provide a friction bonding structure that is small in size and low in cost.

ここで、図３に示すように、接合板５ａ、５ｂ、５ｃ、５ｆ、５ｇ、５ｈの梁３ａ、３ｂと接する面には、凸部９ａ、９ｂ、９ｃ、９ｄ、９ｇ、９ｈ、９ｉ、９ｊが設けられ、梁３ａの接合板５ａ、５ｂ、５ｃ、５ｆ、５ｇ、５ｈと接する面には、溝部１１ａ、１１ｂ、１１ｃ、１１ｄ、１１ｇ、１１ｈ、１１ｉ、１１ｊが設けられている。

A groove (not shown) is also provided on the surface of the beam 3b that contacts the joining plates 5a, 5b, 5c, 5d, and 5e.

即ち、接合板５ａ、５ｂ、５ｃ、５ｄ、５ｅ、５ｆ、５ｇ、５ｈと梁３ａ、３ｂは高力ボルトの軸力によって締結され、これによって溝部１１ａ、１１ｂ、１１ｃ、１１ｄ、１１ｅ、１１ｆ、１１ｇ、１１ｈ、１１ｉ、１１ｊと凸部９ａ、９ｂ、９ｃ、９ｄ、９ｅ、９ｆ、９ｇ、９ｈ、９ｉ、９ｊの間に発生する摩擦力によって接合板と梁を接合している。
なお、梁３ａ、３ｂの、接合板に接合される側の端部は、溝部を一体に成形した部材を溶接等によって取り付けた構造になっている（図２の点線部参照）。 That is, the joining plates 5a, 5b, 5c, 5d, 5e, 5f, 5g, and 5h and the beams 3a and 3b are fastened by the axial force of the high-strength bolts, whereby the grooves 11a, 11b, 11c, 11d, 11e, 11f, The joining plate and the beam are joined by the frictional force generated between 11g, 11h, 11i, 11j and the convex portions 9a, 9b, 9c, 9d, 9e, 9f, 9g, 9h, 9i, 9j.
Note that the ends of the beams 3a and 3b on the side to be joined to the joining plate have a structure in which a member formed integrally with a groove is attached by welding or the like (see the dotted line in FIG. 2).

凸部９ａ、９ｂ、９ｃ、９ｄ、９ｅ、９ｆ、９ｇ、９ｈおよび溝部１１ａ、１１ｂ、１１ｃ、１１ｄ、１１ｅ、１１ｆ、１１ｇ、１１ｈは、凸部もしくは溝部の長手方向と高力ボルトの押圧方向で形成される平面に対して傾斜して設けられており、三角形状を有している。   The convex portions 9a, 9b, 9c, 9d, 9e, 9f, 9g, 9h and the groove portions 11a, 11b, 11c, 11d, 11e, 11f, 11g, 11h are the longitudinal direction of the convex portions or groove portions and the pressing direction of the high-strength bolts. Are inclined with respect to the plane formed by the above, and have a triangular shape.

ここで、溝部と凸部の間で発生する摩擦力について図５および図６を用いて説明する。図５は梁３ａの溝部１１ｉと、接合板５ｇの凸部９ｉ付近の詳細図であって、図６は角度（２θ）と見かけの摩擦係数（Ｆ／Ｃ）の関係を示す図である。
なお、図５では高力ボルトの表記を省略してある。 Here, the frictional force generated between the groove and the protrusion will be described with reference to FIGS. 5 and 6. FIG. 5 is a detailed view of the vicinity of the groove portion 11i of the beam 3a and the convex portion 9i of the bonding plate 5g, and FIG. 6 is a diagram showing the relationship between the angle (2θ) and the apparent friction coefficient (F / C).
In FIG. 5, the high-strength bolt is not shown.

図５に示すように、高力ボルトが接合板５ｇと梁３ａを締め付けることによって、凸部９ｉと溝部１１ｉの間には垂直抗力３１ａ、３１ｂが生じる。   As shown in FIG. 5, when the high-strength bolts fasten the joining plate 5g and the beam 3a, vertical drag forces 31a and 31b are generated between the convex portion 9i and the groove portion 11i.

この垂直抗力３１ａ、３１ｂをＮとし、溝部１１ｉの角度３５をθとすると、接合板５ｇと梁３ａの間の押圧力Ｃとの関係は以下の式で表される。
Ｃ＝２Ｎ・ｓｉｎθ
即ち、押圧力Ｃは垂直高力３１ａ、３１ｂの鉛直成分３３ａ、３３ｂの和となる。 When the vertical drag forces 31a and 31b are N and the angle 35 of the groove 11i is θ, the relationship between the pressing force C between the joining plate 5g and the beam 3a is expressed by the following equation.
C = 2N · sinθ
That is, the pressing force C is the sum of the vertical components 33a and 33b of the vertical high forces 31a and 31b.

従って摩擦力をＦとすると、接合板５ｆと梁３ａの見かけの摩擦係数μは以下の式で表される。
μ＝Ｆ／Ｃ＝Ｆ／（２Ｎ・ｓｉｎθ） Accordingly, when the frictional force is F, the apparent friction coefficient μ between the joining plate 5f and the beam 3a is expressed by the following equation.
μ = F / C = F / (2N · sin θ)

μ（Ｆ／Ｃ）はθが小さいほど大きくなり、例えば図６に示すように、θ＝３０°の時は、平面の場合（２θ＝１８０°の場合）と比べ、２倍の値になる。   μ (F / C) increases as θ decreases. For example, as shown in FIG. 6, when θ = 30 °, the value is twice that of a flat surface (2θ = 180 °). .

従って、溝部１１ｉの傾斜の角度θを小さく形成することにより、接合板５ｆと梁３ａの材質や、高力ボルトの締め付け力を変更することなく、見かけの摩擦係数を大きくすることができる。   Therefore, by forming the inclination angle θ of the groove 11i small, the apparent friction coefficient can be increased without changing the material of the joining plate 5f and the beam 3a and the tightening force of the high strength bolt.

見かけの摩擦係数が大きくなると、小さい軸力で大きな摩擦力を得ることができるため、高力ボルトの本数を減らしたり、径を小さくしたりすることができ、摩擦接合構造１を小型化することができる。   When the apparent friction coefficient is increased, a large frictional force can be obtained with a small axial force. Therefore, the number of high-strength bolts can be reduced and the diameter can be reduced, and the friction joining structure 1 can be reduced in size. Can do.

なお接合板５ａ、５ｂ、５ｃ、５ｄ、５ｅ、５ｆ、５ｈと梁３ａ、３ｂの間に発生する見かけの摩擦力も接合板５ｆと梁３ａの場合と同様であるため、説明を省略する。   The apparent frictional force generated between the joining plates 5a, 5b, 5c, 5d, 5e, 5f, and 5h and the beams 3a and 3b is the same as that of the joining plates 5f and the beams 3a, and thus description thereof is omitted.

ところで、凸部９ａ、９ｂ、９ｃ、９ｄ、９ｅ、９ｆ、９ｇ、９ｈ、９ｉ、１１ｊ、溝部１１ａ、１１ｂ、１１ｃ、１１ｄ、１１ｅ、１１ｆ、１１ｇ、１１ｈ、１１ｊ、１３ｈ、１３ｉ、１３ｊの形状は三角形状に限られない。   By the way, the shape of convex part 9a, 9b, 9c, 9d, 9e, 9f, 9g, 9h, 9i, 11j, groove part 11a, 11b, 11c, 11d, 11e, 11f, 11g, 11h, 11j, 13h, 13i, 13j Is not limited to a triangular shape.

図７〜図９は凸部９ｉおよび溝部１１ｉの形状の変形例である。なお、凸部９ａ、９ｂ、９ｃ、９ｄ、９ｅ、９ｆ、９ｇ、９ｈ、１１ｊおよび溝部１１ａ、１１ｂ、１１ｃ、１１ｄ、１１ｅ、１１ｆ、１１ｇ、１１ｈ、１１ｊ、１３ｈ、１３ｊも溝部１１ｉおよび凸部９ｉと同様であるため、説明を省略する。   7 to 9 are modified examples of the shapes of the convex portion 9i and the groove portion 11i. In addition, convex part 9a, 9b, 9c, 9d, 9e, 9f, 9g, 9h, 11j and groove part 11a, 11b, 11c, 11d, 11e, 11f, 11g, 11h, 11j, 13h, 13j are also groove part 11i and convex part. Since it is the same as 9i, description is abbreviate | omitted.

図７に示すように、接合板４０に台形（多角形）状の凸部４１を設け、梁４２に台形（多角形）状の溝部４３を設けてもよい。
また、図８に示すように、接合板４０ａに円弧状の凸部４１ａを設け、梁４２ａに円弧状の溝部４３ａを設けてもよい。 As shown in FIG. 7 , a trapezoidal (polygonal) convex portion 41 may be provided on the joining plate 40, and a trapezoidal (polygonal) groove 43 may be provided on the beam 42.
Moreover, as shown in FIG. 8 , the arcuate convex part 41a may be provided in the joining plate 40a, and the arcuate groove part 43a may be provided in the beam 42a.

さらに、凸部と溝部の形状は必ずしも同じである必要はなく、例えば図９に示すように、接合板４０ｂに円弧状の凸部４１ｂを設け、梁４２ｂに三角形状の溝部４３ｂを設けてもよい。   Furthermore, the shape of the convex part and the groove part is not necessarily the same. For example, as shown in FIG. 9, the arcuate convex part 41b may be provided on the joining plate 40b, and the triangular groove part 43b may be provided on the beam 42b. Good.

このように、本実施の形態によれば、摩擦接合構造１は、梁３ａ、３ｂが接合板５ａ、５ｂ、５ｃ、５ｄ、５ｅ、５ｆ、５ｇ、５ｈに挟まれるように設けられており、接合板と梁の接する面には凸部９ａ、９ｂ、９ｃ、９ｄ、９ｅ、９ｆ、９ｇ、９ｈ、９ｉ、９ｊおよび凸部に対応する溝部１１ａ、１１ｂ、１１ｃ、１１ｄ、１１ｅ、１１ｆ、１１ｇ、１１ｈ、１１ｉ、１１ｊ、１３ｈ、１３ｉ、１３ｊが設けられている。
従って、みかけの摩擦係数を大きくできるため、摩擦接合構造１を小型化することができ、コストが低減される。 Thus, according to the present embodiment, the friction joining structure 1 is provided so that the beams 3a and 3b are sandwiched between the joining plates 5a, 5b, 5c, 5d, 5e, 5f, 5g, and 5h.

Therefore, since the apparent friction coefficient can be increased, the friction bonding structure 1 can be reduced in size, and the cost is reduced.
