Description

本発明はブレース材、地震発生時の地震エネルギーを吸収する軸力材と、これを補剛する補剛管とを具備するブレース材に関する。   The present invention relates to a brace material including a brace material, an axial force material that absorbs seismic energy when an earthquake occurs, and a stiffening tube that stiffens the material.

従来、建築構造物に設置され、地震発生に対処するためのブレース材は、地震エネルギーを吸収する軸力材と、軸力材の長手方向に圧縮力が作用したときに面外（長手方向に直角方向）の撓みを拘束する補剛材と、を具備し、圧縮軸力作用時にも軸力材の全体座屈の発生を防止ないしは発生時期を遅らせて、安定した軸方向変形を生じせしめて、地震エネルギーの吸収能力を大きくするようになっている。
そして、特許出願人は、軸力材と補剛材とを所定の形態に配置するための溶接作業や軸力材と補剛材との間にモルタルを詰める作業を排除して、容易に製造することができ、また、重量の増加を防止することができるブレース材を開示している（例えば、特許文献１参照）。 Conventionally, brace materials that are installed in building structures and cope with the occurrence of earthquakes are an axial force material that absorbs earthquake energy and an out-of-plane (longitudinal direction) when compressive force acts in the longitudinal direction of the axial force material. A stiffener that constrains the bending in the right-angle direction), and prevents the occurrence of overall buckling of the axial force member even when a compressive axial force is applied, or delays the generation time to cause stable axial deformation. The seismic energy absorption capacity has been increased.
The patent applicant can easily manufacture by eliminating the welding work to arrange the axial force material and the stiffener in a predetermined form and the work of filling the mortar between the axial force material and the stiffener. The brace material which can be made and can prevent the increase in weight is disclosed (for example, refer patent document 1).

特開２０１３−１１２９４９号公報（第４−５頁、図１）JP 2013-112949 A (page 4-5, FIG. 1)

前記特許文献１に開示されたブレース材は、補剛管を貫通する棒鋼からなる軸力材の両端に、それぞれクレビスがねじ接続されている。そして、補剛管および軸力材にそれぞれ螺合する止めリングを介して、補剛管の一方の端部は軸力材の一方の端部にねじ固定されている。一方、軸力材の他方の端部には、鋼管からなるスリーブがねじ固定され、スリーブは長手方向の略半分が補剛管内に侵入し、残りの略半分が補剛管から露出している。このとき、スリーブの外周と補剛管の内周との間に、所定の大きさの隙間が形成されている。したがって、かかるブレース材は、溶接作用をすることなく、軸力材を補剛管に対して所定の位置に配置することができ、また、軸力材と補剛材との間にモルタルを詰める作業を排除することができるという顕著な効果を奏する。   In the brace material disclosed in Patent Document 1, clevises are screwed to both ends of an axial force member made of steel bar that penetrates a stiffening tube. Then, one end portion of the stiffening tube is screwed to one end portion of the axial force member through a stop ring screwed to the stiffening tube and the axial force member. On the other hand, a sleeve made of a steel pipe is screwed to the other end portion of the axial force member, and about half of the longitudinal direction of the sleeve enters the stiffening pipe, and the other half is exposed from the stiffening pipe. . At this time, a gap of a predetermined size is formed between the outer periphery of the sleeve and the inner periphery of the stiffening tube. Therefore, this brace material can arrange | position an axial force material in a predetermined position with respect to a stiffening pipe | tube, without performing a welding effect | action, and stuffs mortar between an axial force material and a stiffening material. There is a remarkable effect that the work can be eliminated.

しかしながら、スリーブの肉厚は、補剛材の内径と軸力材の外径との差の半分よりも小さくする必要があり、一方、補剛材の内面は、補剛性能を発揮するために、軸力材の外面に近い位置にあることが好ましい。
このため、スリーブの肉厚には自ずと限界があり、かかる限界によって、スリーブの曲げ耐力が小さい場合には、スリーブの補剛管から露出している範囲に曲げによる降伏が生じるおそれがある。そうすると、補剛管の他方の端面と軸力材の他方の端部にねじ固定されたクレビスの端部との間は、補剛管がもともとなく、また、スリーブも降伏しているから、かかる間において、軸力材が座屈するおそれがあった。
そのため、スリーブに代わる機構によって曲げ耐力を高めた（大きい）ブレース材が要請されていた。 However, the wall thickness of the sleeve needs to be smaller than half the difference between the inner diameter of the stiffener and the outer diameter of the axial force member, while the inner surface of the stiffener has the capacity to exhibit the stiffening ability. It is preferable that it is in a position close to the outer surface of the axial force member.
For this reason, there is a limit to the wall thickness of the sleeve. If the bending resistance of the sleeve is small due to such a limit, yielding due to bending may occur in the range exposed from the stiffening tube of the sleeve. Then, since the stiffening tube is not originally formed between the other end face of the stiffening tube and the end of the clevis screwed to the other end of the axial force member, the sleeve also yields. In the meantime, the axial force member may be buckled.
Therefore, there has been a demand for a (large) brace material having an increased bending strength by a mechanism that replaces the sleeve.

本発明は上記要請に応えるものであって、曲げ耐力の高い（大きい）ブレース材を提供することを目的とする。   The present invention meets the above-described needs, and an object thereof is to provide a brace material having a high bending strength (large).

（ｉ）本発明に係るブレース材は、補剛管の長手方向の一方の端部が口金に設置され、補剛管の長手方向の他方の端面から所定の範囲が、補強材によって包囲されている。すなわち、補強材は補剛管の外周を包囲するもので、その厚さが制限されるものでないから、従来のスリーブ（軸力材と補剛管との隙間に配置される）に比較して、外径（内径も同じ）および肉厚を大きくすることができるため、剛性を高めることが可能になる。
このとき、補剛管の長手方向の他方の端面から所定の範囲は、剛性の高い補強材によって、変形が拘束されるため、軸力材の座屈の発生が抑えられることから、曲げ耐力の高い（大きい）ブレース材になっている。
（ｉｉ）また、補剛管の長手方向の両方の端部から所定の範囲が、それぞれ補強材によって包囲されている場合には、前記効果が得られると共に、口金が不要になることによって、部品の種類を減らすことができ、製造コストや在庫コストを抑えることができる。
（ｉｉｉ）さらに、補強材の外径は先端に向かって（補剛管の長手方向の中央に近づくほど）、小さくなるから、長手方向の各位置における強度を確保した上で、軽量化の促進および意匠性の向上を図ることができる。 (I) In the brace material according to the present invention, one end portion in the longitudinal direction of the stiffening tube is installed in the base, and a predetermined range from the other end surface in the longitudinal direction of the stiffening tube is surrounded by the reinforcing material. Yes. In other words, the reinforcing material surrounds the outer periphery of the stiffening tube, and its thickness is not limited. Compared to a conventional sleeve (arranged between the axial force member and the stiffening tube). Since the outer diameter (the inner diameter is the same) and the wall thickness can be increased, the rigidity can be increased.
At this time, the predetermined range from the other end face in the longitudinal direction of the stiffening tube is restrained from being deformed by a stiff reinforcing material, so that the occurrence of buckling of the axial force material is suppressed, so that the bending strength is reduced. It is a high (large) brace material.
(Ii) In addition, when a predetermined range from both ends in the longitudinal direction of the stiffening tube is surrounded by the reinforcing material, the above-described effect can be obtained, and the base is not necessary, The number of types can be reduced, and manufacturing costs and inventory costs can be suppressed.
(Iii) Furthermore, since the outer diameter of the reinforcing material becomes smaller toward the tip (approaching the center in the longitudinal direction of the stiffening tube), the weight reduction is promoted while ensuring the strength at each position in the longitudinal direction. In addition, the design can be improved.

In addition, a tapered portion 50c is formed on the outer surface of the cylindrical portion 52. The tapered portion 50c decreases as the outer diameter approaches one end surface (same as the tip) 50a in the longitudinal direction. For this reason, since the impression which reinforces the stiffening pipe | tube 20 smoothly is given, the design property is improving.

（補強材クレビス）
補強材クレビス６０は、口金クレビス４０に同じであって、建築構造物（図示しない）に設置するための継手として機能するものであって、円盤状部分６１と、円盤状部分６１の一方の端面に設置された板状部分６２と、板状部分６２を貫通する取付用孔６６と、円盤状部分６１の外周に形成された雄ネジ６５とを有している。このとき、取付用孔６６の中心線と雄ネジ６５の中心線とは直角に交差している（幾何学的に正確に交差する意味ではなく、工業的な精度で交差している）。

（作用効果）
ブレース材１００は、補剛管２０の長手方向の一方の端部２１ａが口金３０に設置され、補剛管２０の長手方向の他方の端面２０ｂから所定の範囲が、補強材５０の筒状部５２によって包囲されている。すなわち、筒状部５２は補剛管２０の外周を包囲するもので、その厚さが制限されるものでないから、従来のスリーブ（軸力材と補剛管との隙間に配置される）に比較して、外径（内径も同じ）および肉厚を大きくすることができるため、剛性を高めることが可能になる。
そうすると、補剛管２０の長手方向の他方の端面２０ｂから所定の範囲は、剛性の高い補強材５０の筒状部５２によって、変形が拘束されるため、軸力材１０の座屈の発生が抑えられる（これについては別途詳細に説明する）。
また、補強材５０の外径は長手方向の一方の端面５０ａ（先端）に向かって（補剛管２０の長手方向の中央に近づくほど）、小さくなるから、長手方向の各位置における強度を確保した上で、軽量化の促進および意匠性の向上を図ることができる。
また、軸力材１０の両端はそれぞれ口金３０および補強材５０にネジ接続されているから、それぞれのネジを逆方向にする（例えば、雄ネジ１２ａおよび雌ネジ３１を右ネジにして、雄ネジ１２ｂおよび雌ネジ５１を左ネジにする）ことによって、取付用孔４４と取付用孔６６との距離を調整することができるから、ブレース材１００の設置が容易になる。 (Function and effect)
In the brace material 100, one end portion 21 a in the longitudinal direction of the stiffening tube 20 is installed in the base 30, and a predetermined range from the other end surface 20 b in the longitudinal direction of the stiffening tube 20 is a cylindrical portion of the reinforcing material 50. Surrounded by 52. That is, since the cylindrical part 52 surrounds the outer periphery of the stiffening tube 20 and the thickness thereof is not limited, the conventional sleeve (arranged in the gap between the axial force member and the stiffening tube) is used. In comparison, since the outer diameter (the inner diameter is the same) and the wall thickness can be increased, the rigidity can be increased.
Then, since the deformation is constrained by the cylindrical portion 52 of the reinforcing member 50 having high rigidity in a predetermined range from the other end surface 20b in the longitudinal direction of the stiffening tube 20, occurrence of buckling of the axial force member 10 occurs. (This will be described in detail separately.)
Further, since the outer diameter of the reinforcing member 50 becomes smaller toward one end face 50a (tip) in the longitudinal direction (as it approaches the longitudinal center of the stiffening tube 20), the strength at each position in the longitudinal direction is ensured. In addition, it is possible to promote weight reduction and improve design properties.
Further, since both ends of the axial force member 10 are screw-connected to the base 30 and the reinforcing member 50, respectively, the respective screws are set in opposite directions (for example, the male screw 12a and the female screw 31 are set to the right screw, and the male screw is set. Since the distance between the mounting hole 44 and the mounting hole 66 can be adjusted by making the left screw 12b and the female screw 51), the brace material 100 can be easily installed.

図６において、ブレース材２００は、軸力材１０と、軸力材１０が貫通し、軸力材１０を包囲して軸力材１０の面外変形を拘束するための補剛管２０と、軸力材１０の長手方向の一方の端部１１ａおよび補剛管２０の長手方向の一方の端部２１ａが設置された口金２３０と、軸力材１０および補剛管２０とは反対の方向に突出するように口金２３０に設置され、建築構造物（図示しない）に設置するための継手となる口金クレビス４０と、軸力材１０の長手方向の他方の端部１１ｂが設置された補強材２５０と、軸力材１０とは反対の方向に突出するように補強材２５０に設置され、建築構造物（図示しない）に設置するための継手となる補強材クレビス６０と、を有している。 [Embodiment 2]
6A and 6B illustrate a brace material according to Embodiment 2 of the present invention, in which FIG. 6A is a side view, and FIG. 6B is a cross-sectional view of the main part in side view. In addition, the same code | symbol is attached | subjected to the part which is the same as that of Embodiment 1, or an equivalent part, and one part description is abbreviate | omitted. The relative size and thickness of each member are not limited to the illustrated dimensions.
In FIG. 6, the brace material 200 includes an axial force member 10, a stiffening tube 20 through which the axial force member 10 penetrates and restrains the axial force member 10 from being deformed out of plane. The base 230 on which one end portion 11a in the longitudinal direction of the axial force member 10 and one end portion 21a in the longitudinal direction of the stiffening tube 20 are installed, and the axial force member 10 and the stiffening tube 20 in the opposite direction.

［実施の形態３］
図７は本発明の実施の形態３に係るブレース材を説明するものであって、（ａ）は側面図、（ｂ）は主要部の側面視の断面図である。なお、実施の形態１と同じ部分または相当する部分には同じ符号を付し、一部の説明を省略する。各部材の相対的な大きさや板厚等は図示する寸法に限定されるものではない。
図７において、ブレース材３００は、軸力材１０と、軸力材１０が貫通し、軸力材１０を包囲して軸力材１０の面外変形を拘束するための補剛管２０と、軸力材１０の長手方向の一方の端部１１ａおよび補剛管２０の長手方向の一方の端部２１ａが設置された一方側補強材３５０と、軸力材１０および補剛管２０とは反対の方向に突出するように一方側補強材３５０に設置され、建築構造物（図示しない）に設置するための継手となる口金クレビス４０と、軸力材１０の長手方向の他方の端部１１ｂが設置された補強材５０と、軸力材１０とは反対の方向に突出するように補強材５０に設置され、建築構造物（図示しない）に設置するための継手となる補強材クレビス６０と、を有している。 [Embodiment 3]
7A and 7B illustrate a brace material according to Embodiment 3 of the present invention, in which FIG. 7A is a side view and FIG. 7B is a cross-sectional view of the main part in side view. In addition, the same code | symbol is attached | subjected to the part which is the same as that of Embodiment 1, or an equivalent part, and one part description is abbreviate | omitted. The relative size and thickness of each member are not limited to the illustrated dimensions.
In FIG. 7, the brace material 300 includes an axial force member 10, a stiffening tube 20 through which the axial force member 10 penetrates and restrains the axial force member 10 from being deformed out of plane. The one side reinforcing member 350 provided with one end portion 11a in the longitudinal direction of the axial force member 10 and one end portion 21a in the longitudinal direction of the stiffening tube 20 is opposite to the axial force member 10 and the stiffening tube 20. A base clevis 40 that is a joint for installation on a building structure (not shown), and the other end portion 11b in the longitudinal direction of the axial force member 10 A reinforcing material clevis 60 that is installed in the reinforcing material 50 so as to protrude in the opposite direction to the axial force material 10 and serves as a joint for installation in a building structure (not shown); have.

すなわち、ブレース材３００は、ブレース材１００（実施の形態１）の口金３０に代えて、一方側補強材３５０を有し、一方側補強材３５０は補強材５０に同じである。
したがって、補剛管２０の一方の端部２１ａは、補強材５０によって補強される他方の端部２１ｂと同様に、一方側補強材３５０によって補強されている。そして、この点を除き、ブレース材３００はブレース材１００に同じである。
このため、ブレース材３００は、一方側補強材３５０および補強材２５０によって補強された補剛管２０が、軸力材１０の面外変形を拘束するから、曲げ耐力が高く（大きく）なると共に、製造コストが安価になっている。
すなわち、口金３０を製造する必要がなくなるから、口金３０を鋳造するための金型が不要になると共に、ブレース材３００を構成する部品の種類が少なくなるため、在庫管理が容易になる。
なお、ブレース材３００は一対の補強材５０を有するものであるが、補強材５０に代えて、一対の補強材２５０を有してもよい。 That is, the brace material 300 includes a one-side reinforcing material 350 instead of the base 30 of the brace material 100 (Embodiment 1), and the one-side reinforcing material 350 is the same as the reinforcing material 50.
Accordingly, one end 21 a of the stiffening tube 20 is reinforced by the one-side reinforcing member 350 in the same manner as the other end 21 b reinforced by the reinforcing member 50. Except for this point, the brace material 300 is the same as the brace material 100.
For this reason, since the stiffening pipe 20 reinforced by the one-side reinforcing member 350 and the reinforcing member 250 restrains the out-of-plane deformation of the axial force member 10, the bracing member 300 has a high (larger) bending strength, Manufacturing costs are low.
That is, since it is not necessary to manufacture the base 30, a mold for casting the base 30 is not required, and the types of parts constituting the brace material 300 are reduced, so that inventory management is facilitated.
The brace material 300 includes a pair of reinforcing members 50, but may include a pair of reinforcing members 250 instead of the reinforcing members 50.

本発明によれば、簡素な構造で曲げ耐力の高い（大きい）ブレース材が得られるから、各種形態の断面形状を有する軸力材についても適用することができるから、建築構造物の様々な要求に対応することができる各種ブレース材として広く利用することができる。   According to the present invention, a brace material having a simple structure and a high bending strength can be obtained, so that it can also be applied to an axial force material having various types of cross-sectional shapes. It can be widely used as various brace materials that can cope with the above.
