Description

本開示は、アルミニウム形材の補強構造に関するものである。 The present disclosure relates to reinforcing structures for aluminum profiles.

従来から、アルミニウム形材は素材自体の軽量性や易加工性の特徴によって、多くの建材に用いられている。近年増加する大型建材においては、強風や積雪による建材のたわみを抑制する手段として、アルミニウム形材の肉厚を厚くしたり、外径を大きくしたりすることによって形材の断面係数を向上させる方法や、中空内部に鋼材を補強部材として挿入しボルト締結や接着剤接合による補強方法を行っている。 BACKGROUND ART Conventionally, aluminum profiles have been used in many building materials due to their lightness and ease of workability. In the case of large building materials, which are increasing in recent years, as a means of suppressing the deflection of building materials due to strong winds and accumulated snow, the section modulus of aluminum profiles is improved by increasing the wall thickness and increasing the outer diameter of the aluminum profiles. Alternatively, a steel material is inserted into the hollow interior as a reinforcing member, and a reinforcement method is performed by bolting or bonding with an adhesive.

The distance between the pair of second ribs 16a is substantially the same as or slightly longer than the plate thickness of the reinforcing member 20, which will be described later.

補強部材２０は、ホローｓ１に配置されている。補強部材２０は、平板状に形成されている。補強部材２０の板面は、Ｔ２方向を向いている。補強部材２０は、形材１０の長手方向の略全長に設けられている。補強部材２０の形状は平板状に限られず、長手方向に直交する断面視で矩形に形成された角管等で形成され、一対の第一リブ１５ａ及び一対の第二リブ１６ａの間隔を長くして、その間に配置される構成であってもよい。 The reinforcing member 20 is arranged in the hollow s1. The reinforcing member 20 is formed in a flat plate shape. The plate surface of the reinforcing member 20 faces the T2 direction. The reinforcement member 20 is provided over substantially the entire length of the shape member 10 in the longitudinal direction. The shape of the reinforcing member 20 is not limited to a flat plate shape, and is formed of a rectangular tube or the like having a rectangular cross-section perpendicular to the longitudinal direction. and may be arranged between them.

補強部材２０は、形材１０を形成するアルミニウム材料とは異なる材料で形成されている。補強部材２０は、アルミニウム材料よりも高剛性の材料で形成されている。補強部材２０は、例えばＣＦＲＰ（Ｃａｒｂｏｎ Ｆｉｂｅｒ Ｒｅｉｎｆｏｒｃｅｄ Ｐｌａｓｔｉｃｓ）や鋼材等で形成されている。 The reinforcing member 20 is made of a material different from the aluminum material forming the profile 10 . The reinforcing member 20 is made of a material having higher rigidity than aluminum material. The reinforcing member 20 is made of CFRP (Carbon Fiber Reinforced Plastics), steel, or the like, for example.

補強部材２０は、形材１０と非接合状態の関係にある。補強部材２０は、形材１０と接着剤等の化学的接着や、両面テープや、ボルト締結等の機械的締結がされていない。 The reinforcing member 20 is in a non-bonded relationship with the shape member 10 . The reinforcing member 20 is not chemically bonded to the shape member 10 using an adhesive, double-sided tape, or mechanically fastened by bolts or the like.

補強部材２０の一方の端部２０ａは、第一レール１５に保持され、一対の第一リブ１５ａに挟み込まれている。補強部材２０の他方の端部２０ａは、第二レール１６に保持され、一対の第二リブ１６ａに挟み込まれている。 One end 20a of the reinforcing member 20 is held by the first rail 15 and sandwiched between the pair of first ribs 15a. The other end 20a of the reinforcing member 20 is held by the second rail 16 and sandwiched between the pair of second ribs 16a.

補強部材２０の端部２０ａは、第一板部１１及び第二板部１２に当接しているか、または第一板部１１及び第二板部１２とわずかに隙間をあけて配置されている。 The end portion 20a of the reinforcing member 20 is in contact with the first plate portion 11 and the second plate portion 12, or is arranged with a slight gap between the first plate portion 11 and the second plate portion 12.

形材１０には、使用状態でＴ１方向に外力等の荷重が作用する。建具の横框や横枠において、形材１０の長手方向が建具の幅方向を向くように使用する場合には、重力や屋内外方向の空気圧等によって第一方向Ｔ１方向に荷重が作用することになる。建具の縦框や縦枠において、形材１０の長手方向が上下方向を向くように使用する場合には、障子の開閉や屋内外方向の空気圧等によって第一方向Ｔ１方向に荷重が作用することになる。 A load such as an external force acts on the shaped member 10 in the T1 direction in use. When the horizontal stiles and frames of fittings are used so that the longitudinal direction of the shape member 10 faces the width direction of the fittings, a load acts in the first direction T1 due to gravity, indoor/outdoor air pressure, and the like. become. When the longitudinal direction of the shape member 10 is directed vertically in the vertical frame or vertical frame of the fittings, the load acts in the first direction T1 due to the opening and closing of the shoji, the air pressure in the indoor and outdoor directions, and the like. become.

Ｔ１方向に荷重が作用した際には、補強部材２０の端部２０ａが第一板部１１及び第二板部１２に当接して、Ｔ１方向に突っ張ることで、第一板部１１及び第二板部１２のたわみ等の形材１０の変形が抑制される。 When a load acts in the T1 direction, the end portion 20a of the reinforcing member 20 abuts against the first plate portion 11 and the second plate portion 12 and stretches in the T1 direction, so that the first plate portion 11 and the second plate portion 12 Deformation of the shape member 10 such as deflection of the plate portion 12 is suppressed.

補強部材２０を形材１０の内部に配置する際には、補強部材２０の長手方向の端部から、一対の第一リブ１５ａの間及び一対の第二リブ１６ａの間に挿入するだけでよい。 When arranging the reinforcing member 20 inside the shaped member 10, it is only necessary to insert the reinforcing member 20 from the longitudinal end between the pair of first ribs 15a and between the pair of second ribs 16a. .

このように構成されたアルミニウム形材の補強構造１では、形材１０にＴ１方向に荷重が作用すると、補強部材２０がＴ１方向に突っ張って荷重に対して抗する。補強部材２０は形材１０のホローに配置されているため、形材１０の肉厚等の形材１０自体を大きくする必要がなく、形材１０の大きさを抑えることができる。 In the reinforcing structure 1 of the aluminum profile configured in this way, when a load acts on the profile 10 in the T1 direction, the reinforcing member 20 stretches in the T1 direction to resist the load. Since the reinforcing member 20 is arranged in the hollow of the shape member 10, the size of the shape member 10 can be suppressed without increasing the thickness of the shape member 10 itself.

アルミニウム形材の補強構造１では、補強部材２０は形材１０を形成するアルミニウム材料とは異なる材料で形成され、補強部材２０と形材１０とでは熱膨張率の差がある場合がある。補強部材２０は形材１０とは接合されていないため、温度変化によって補強部材２０及び形材１０の一方の変形が他方の変形に影響を及ぼすことが抑制される。 In the aluminum profile reinforcement structure 1 , the reinforcement member 20 is made of a material different from the aluminum material forming the profile 10 , and there may be a difference in thermal expansion coefficient between the reinforcement member 20 and the profile 10 . Since the reinforcing member 20 is not joined to the shape member 10, the deformation of one of the reinforcing member 20 and the shape member 10 is suppressed from affecting the deformation of the other due to temperature changes.

アルミニウム形材の補強構造１では、補強部材２０を保持する一対の第一リブ１５ａ及び一対の第二リブ１６ａが形材１０のホローｓ１に設けられている。これによって、補強部材２０のガタツキや位置ずれ等が抑制される。 In the reinforcing structure 1 of the aluminum profile, a pair of first ribs 15a and a pair of second ribs 16a for holding the reinforcing member 20 are provided in the hollow s1 of the profile 10. As shown in FIG. As a result, rattling, displacement, and the like of the reinforcing member 20 are suppressed.

アルミニウム形材の補強構造１では、補強部材２０は、形材１０にＴ２方向に間隔をあけて設けられた一対の第一リブ１５ａ及び一対の第二リブ１６ａによって保持されている。これによって、補強部材２０のＴ２方向への移動が規制される。 In the reinforcing structure 1 of the aluminum profile, the reinforcing member 20 is held by a pair of first ribs 15a and a pair of second ribs 16a provided on the profile 10 with an interval in the T2 direction. This restricts the movement of the reinforcing member 20 in the T2 direction.

（第二実施形態）
次に、第二実施形態に係るアルミニウム形材の補強構造について、主に図２を用いて説明する。下記に示す実施形態の説明において、前述した部材と同一の部材には同一の符号を付して、その説明を省略する。 (Second embodiment)
Next, the reinforcing structure of the aluminum profile according to the second embodiment will be described mainly with reference to FIG. In the description of the embodiments shown below, the same reference numerals are given to the same members as those described above, and the description thereof will be omitted.

図２に示すように、アルミニウム形材の補強構造１Ａでは、補強部材２０は、一対のアタッチメント（保持部）３０によって保持されている。アタッチメント３０は、形材１０のホローｓ１に配置されている。アタッチメント３０は、補強部材２０を挟んでＴ２方向の両側に配置されている。一対のアタッチメント３０は、Ｔ２方向の中心で対称配置されている。 As shown in FIG. 2 , in the reinforcing structure 1</b>A of aluminum profiles, the reinforcing member 20 is held by a pair of attachments (holding portions) 30 . The attachment 30 is arranged in the hollow s1 of the profile 10 . The attachments 30 are arranged on both sides of the reinforcing member 20 in the T2 direction. A pair of attachments 30 are arranged symmetrically at the center in the T2 direction.

アタッチメント３０は、短尺部材である。アタッチメント３０は、形材１０の長手方向に間隔をあけて複数配置されている。 The attachment 30 is a short member. A plurality of attachments 30 are arranged at intervals in the longitudinal direction of the shaped member 10 .

アタッチメント３０は、長手方向に直交する断面視で略Ｃ字状に形成されている。アタッチメント３０は、保持壁部３１と、折曲壁部３２と、を有している。 The attachment 30 is formed in a substantially C shape when viewed in cross section orthogonal to the longitudinal direction. The attachment 30 has a holding wall portion 31 and a bent wall portion 32 .

保持壁部３１は、平板状に形成されている。保持壁部３１の板面は、Ｔ２方向を向いている。保持壁部３１は、補強部材２０におけるＴ２方向を向く面２０ｂに沿って配置されている。保持壁部３１のＴ２方向の一方の端部３１ａは、第一板部１１まで達していない。保持壁部３１のＴ２方向の他方の端部３１ａは、第二板部１２まで達していない。 The holding wall portion 31 is formed in a flat plate shape. The plate surface of the holding wall portion 31 faces the T2 direction. The holding wall portion 31 is arranged along the surface 20b of the reinforcing member 20 facing in the T2 direction. One end 31 a of the holding wall portion 31 in the T2 direction does not reach the first plate portion 11 . The other end 31 a of the holding wall portion 31 in the T2 direction does not reach the second plate portion 12 .

折曲壁部３２は、保持壁部３１のＴ１方向の両端部３１ａから補強部材２０の面２０ｂから離れる方向に延びている。折曲壁部３２の端部３２ａは、第三板部１３及び第四板部１４に当接しているか、またはわずかに隙間をあけて配置されている。 The bent wall portion 32 extends from both end portions 31a of the holding wall portion 31 in the T1 direction in a direction away from the surface 20b of the reinforcing member 20 . An end portion 32a of the bent wall portion 32 is in contact with the third plate portion 13 and the fourth plate portion 14, or is arranged with a slight gap therebetween.

保持壁部３１は、補強部材２０にスポンジ状の両面テープ３６を用いて接着されている。保持壁部３１は、接着剤や、スポンジ状ではない両面テープを用いて補強部材２０に接着されていてもよい。補強部材２０は、Ｔ２方向の両側からアタッチメント３０によって挟み込まれている。 The holding wall portion 31 is adhered to the reinforcing member 20 using a sponge-like double-sided tape 36 . The holding wall portion 31 may be adhered to the reinforcing member 20 using an adhesive or a non-sponge double-sided tape. The reinforcing member 20 is sandwiched between attachments 30 from both sides in the T2 direction.

このように構成されたアルミニウム形材の補強構造１Ａでは、形材１０にＴ１方向に荷重が作用すると、補強部材２０がＴ１方向に突っ張って荷重に対して抗する。補強部材２０は形材１０のホローに配置されているため、形材１０の肉厚等の形材１０自体を大きくする必要がなく、形材１０の大きさを抑えることができる。 In the reinforcing structure 1A of the aluminum profile configured in this manner, when a load acts on the profile 10 in the T1 direction, the reinforcing member 20 stretches in the T1 direction to resist the load. Since the reinforcing member 20 is arranged in the hollow of the shape member 10, the size of the shape member 10 can be suppressed without increasing the thickness of the shape member 10 itself.

アルミニウム形材の補強構造１Ａでは、補強部材２０は形材１０を形成するアルミニウム材料とは異なる材料で形成され、補強部材２０と形材１０とでは熱膨張率の差がある場合がある。補強部材２０は形材１０とは接合されていないため、温度変化によって補強部材２０及び形材１０の一方の変形が他方の変形に影響を及ぼすことが抑制される。 In the aluminum profile reinforcing structure 1A, the reinforcing member 20 is made of a material different from the aluminum material forming the profile 10, and the reinforcing member 20 and the profile 10 may have different coefficients of thermal expansion. Since the reinforcing member 20 is not joined to the shape member 10, the deformation of one of the reinforcing member 20 and the shape member 10 is suppressed from affecting the deformation of the other due to temperature changes.

アルミニウム形材の補強構造１Ａでは、補強部材２０は、Ｔ２方向の両側からアタッチメント３０で挟み込まれて保持されている。これによって、補強部材２０のＴ２方向への移動が規制される。アタッチメント３０は形材１０と別部材とすることができるため、専用形材とする必要がない。 In the reinforcing structure 1A of the aluminum profile, the reinforcing member 20 is sandwiched and held by the attachments 30 from both sides in the T2 direction. This restricts the movement of the reinforcing member 20 in the T2 direction. Since the attachment 30 can be a separate member from the shape member 10, there is no need to use a special shape member.

アルミニウム形材の補強構造１Ａでは、アタッチメント３０と補強部材２０とは、スポンジ状の両面テープ３６で固定されている。これによって、形材１０に生じる振動がスポンジ状の両面テープ３６で吸収されるため、ガタツキ音を抑制することができる。 In the reinforcing structure 1</b>A of the aluminum profile, the attachment 30 and the reinforcing member 20 are fixed with a sponge-like double-sided tape 36 . As a result, the sponge-like double-faced tape 36 absorbs the vibration generated in the shaped member 10, so that rattling noise can be suppressed.

次に、第三実施形態に係るアルミニウム形材の補強構造について、主に図３を用いて説明する。図３に示すように、補強部材２０Ｂは、ホローｓ１に自立可能に配置されている。補強部材２０Ｂは、形材１０の長手方向に直交する断面視で略矩形状に形成されている。補強部材２０Ｂは、形材１０の長手方向の略全長に配置されている。 (Third embodiment)
Next, the reinforcement structure for the aluminum profile according to the third embodiment will be described mainly with reference to FIG. As shown in FIG. 3, the reinforcing member 20B is arranged in the hollow s1 so as to be able to stand on its own. The reinforcing member 20B is formed in a substantially rectangular shape when viewed in cross section perpendicular to the longitudinal direction of the shaped member 10 . The reinforcement member 20B is arranged over substantially the entire length of the shape member 10 in the longitudinal direction.

補強部材２０Ｂは、第一補強板部２１と、第二補強板部２２と、第三補強板部２３と、第四補強板部２４と、を有している。 The reinforcing member 20</b>B has a first reinforcing plate portion 21 , a second reinforcing plate portion 22 , a third reinforcing plate portion 23 , and a fourth reinforcing plate portion 24 .

第一補強板部２１及び第二補強板部２２は、平板状に形成されている。第一補強板部２１の板面及び第二補強板部２２の板面は、Ｔ１方向を向いている。第一補強板部２１と第二補強板部２２とは、Ｔ１方向に対向して配置されている。第一補強板部２１は、第一板部１１の内面に当接、またはわずかに隙間をあけて配置されている。第二補強板部２２は、第二板部１２の内面に当接、またはわずかに隙間をあけて配置されている。 The first reinforcing plate portion 21 and the second reinforcing plate portion 22 are formed in a flat plate shape. The plate surface of the first reinforcing plate portion 21 and the plate surface of the second reinforcing plate portion 22 face the T1 direction. The first reinforcing plate portion 21 and the second reinforcing plate portion 22 are arranged to face each other in the T1 direction. The first reinforcing plate portion 21 is arranged in contact with the inner surface of the first plate portion 11 or with a slight gap therebetween. The second reinforcing plate portion 22 is arranged in contact with the inner surface of the second plate portion 12 or with a slight gap.

第三補強板部２３及び第四補強板部２４は、第一補強板部２１の端部と第二補強板部２２の端部とを接続している。第三補強板部２３及び第四補強板部２４は、平板状に形成されている。第三補強板部２３の板面及び第四補強板部２４の板面は、Ｔ２方向を向いている。第三補強板部２３と第四補強板部２４とは、Ｔ２方向に対向して配置されている。第三補強板部２３は、第三板部１３の内面に当接、またはわずかに隙間をあけて配置されている。第四補強板部２４は、第四補強板部２４の内面に当接、またはわずかに隙間をあけて配置されている。 The third reinforcing plate portion 23 and the fourth reinforcing plate portion 24 connect the end portion of the first reinforcing plate portion 21 and the end portion of the second reinforcing plate portion 22 . The third reinforcing plate portion 23 and the fourth reinforcing plate portion 24 are formed in a flat plate shape. The plate surface of the third reinforcing plate portion 23 and the plate surface of the fourth reinforcing plate portion 24 face the T2 direction. The third reinforcing plate portion 23 and the fourth reinforcing plate portion 24 are arranged to face each other in the T2 direction. The third reinforcing plate portion 23 is arranged in contact with the inner surface of the third plate portion 13 or with a slight gap therebetween. The fourth reinforcing plate portion 24 is arranged in contact with the inner surface of the fourth reinforcing plate portion 24 or with a slight gap.

形材１０にＴ１方向及びＴ２に荷重が作用すると、補強部材２０ＢがＴ１方向及びＴ２方向に突っ張って荷重に対して抗する。 When a load acts on the shape member 10 in the T1 and T2 directions, the reinforcing member 20B stretches in the T1 and T2 directions to resist the load.

このように構成されたアルミニウム形材の補強構造１Ｂは、形材１０にＴ１方向に荷重が作用すると、補強部材２０ＢがＴ１方向に突っ張って荷重に対して抗する。補強部材２０Ｂは形材１０のホローに配置されているため、形材１０の肉厚等の形材１０自体を大きくする必要がなく、形材１０の大きさを抑えることができる。 In the reinforcing structure 1B of the aluminum profile constructed in this manner, when a load acts on the profile 10 in the T1 direction, the reinforcing member 20B is stretched in the T1 direction to resist the load. Since the reinforcing member 20B is arranged in the hollow of the shape member 10, the size of the shape member 10 can be suppressed without increasing the thickness of the shape member 10 itself.

アルミニウム形材の補強構造１Ｂでは、補強部材２０Ｂは形材１０を形成するアルミニウム材料とは異なる材料で形成され、補強部材２０Ｂと形材１０とでは熱膨張率の差がある場合がある。補強部材２０Ｂは形材１０とは接合されていないため、温度変化によって補強部材２０Ｂ及び形材１０の一方の変形が他方の変形に影響を及ぼすことが抑制される。 In the reinforcing structure 1B of the aluminum profile, the reinforcing member 20B is made of a material different from the aluminum material forming the profile 10, and the reinforcing member 20B and the profile 10 may have different coefficients of thermal expansion. Since the reinforcing member 20B is not joined to the shape member 10, the deformation of one of the reinforcing member 20B and the shape member 10 is suppressed from affecting the deformation of the other due to temperature changes.

アルミニウム形材の補強構造１Ｂでは、補強部材２０Ｂ自体が、ホローで自立可能である。ホローに補強部材２０Ｂを配置すれば補強部材２０Ｂが形材１０を補強するため、簡易な構成とすることができる。 In the reinforcing structure 1B of the aluminum profile, the reinforcing member 20B itself is hollow and can stand on its own. If the reinforcing member 20B is arranged in the hollow, the reinforcing member 20B reinforces the shaped member 10, so that the configuration can be simplified.

例えば、第一実施形態において、形材１０にＴ１方向及びＴ２方向の両方向に荷重が作用する場合には、第三板部１３及び第四板部１４にも第一レール１５のようなレールを設けて、補強部材を長手方向に直交する断面視で十字形にしてもよい。 For example, in the first embodiment, when loads are applied to the shape member 10 in both the T1 direction and the T2 direction, the third plate portion 13 and the fourth plate portion 14 are also provided with a rail such as the first rail 15. may be provided so that the reinforcing member has a cruciform cross-section when viewed perpendicularly to the longitudinal direction.

第三実施形態において、補強部材２０Ｂは、形材１０の長手方向に直交する断面視で略矩形状に形成されていなくてもよい。例えば、補強部材２０Ｂは、形材１０の長手方向に直交する断面視で略Ｈ状に形成されていてもよい。補強部材２０Ｂは、第三補強板部２３及び第四補強板部２４を有しておらず、第一補強板部２１のＴ２方向の中間と第二補強板部２２のＴ２方向の中間とを連結する壁部を有する構成であってもよい。補強部材２０Ｂは、形材１０の長手方向に直交する断面視で略三角形状に形成されていてもよい。三角形の一辺が第一板部１１及び第二板部１２のいずれか一方に当接し、三角形の一辺と対向する頂点が第一板部１１及び第二板部１２の他方に当接する構成であってもよい。 In the third embodiment, the reinforcing member 20B does not have to be formed in a substantially rectangular shape in a cross-sectional view perpendicular to the longitudinal direction of the shaped member 10 . For example, the reinforcing member 20B may be formed in a substantially H shape in a cross-sectional view orthogonal to the longitudinal direction of the shaped member 10. As shown in FIG. The reinforcing member 20B does not have the third reinforcing plate portion 23 and the fourth reinforcing plate portion 24, and is positioned between the middle of the first reinforcing plate portion 21 in the T2 direction and the middle of the second reinforcing plate portion 22 in the T2 direction. A configuration having a connecting wall portion may also be used. The reinforcing member 20B may be formed in a substantially triangular shape in a cross-sectional view orthogonal to the longitudinal direction of the shaped member 10. As shown in FIG.
