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。 This disclosure relates to a reinforcing structure 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。 Traditionally, aluminum profiles have been used in many building materials due to the material's lightweight and easy workability. For the large building materials that have been increasing in number in recent years, methods to prevent the building materials from sagging due to strong winds or snow accumulation include increasing the thickness of the aluminum profile or the outer diameter to improve the section modulus of the profile, or inserting steel material as a reinforcing member into the hollow interior and reinforcing it with bolts or adhesive bonding.

特開２０２０－１１２０２６号公報JP 2020-112026 A

形材の断面係数を向上させる方法では、形材の大型化及び重量化によるデザイン性の低下及び施工性の低下という問題点がある。ボルト締結や接着剤接合による補強方法では、異素材どうしの熱膨張率の差によって、形材や補強部材に歪みが生じたり、接合部分が劣化したりするという問題点がある。 Methods that improve the section modulus of profiles have the problem of reducing design and workability due to the increased size and weight of the profiles. Reinforcement methods that use bolt fastening or adhesive bonding have the problem of distortion of the profiles and reinforcing members and deterioration of joints due to differences in the thermal expansion coefficients of different materials.

本開示は、上記事情に鑑みてなされたものであり、形材の大きさを抑えつつ、温度変化によって形材及び補強部材の一方の変形が他方の変形に影響を及すことを抑制することができるアルミニウム形材の補強構造を提供する。 This disclosure has been made in consideration of the above circumstances, and provides a reinforcing structure for an aluminum profile that can suppress the deformation of either the profile or the reinforcing member due to temperature changes from affecting the deformation of the other, while minimizing the size of the profile.

本開示の一態様に係るアルミニウム形材の補強構造は、アルミニウム材料によって形成され、内部にホローが形成された形材と、該形材と非接合状態で該ホローに配置され、前記アルミニウム材料とは異なる材料で形成された補強部材と、を備え、該補強部材は、前記形材に荷重が作用する第一方向に突っ張るように配置され、前記形材は、長手方向に直交する断面視で略矩形の環状に形成されているとともに、前記第一方向に対向する第一板部と第二板部と、を有し、前記補強部材は、前記第一板部に沿って配置される第一補強板部と、前記第二板部に沿って配置される第二補強板部と、前記第一補強板部と前記第二補強板部とを連結する壁部と、を有し、前記長手方向に直交する断面視で略Ｈ状に形成されていて、前記第一補強板部は、前記第一板部の内面に隙間をあけて配置され、前記第二補強板部は、前記第二板部の内面に隙間をあけて配置されている。 A reinforcement structure for an aluminum profile according to one embodiment of the present disclosure comprises a profile formed of an aluminum material and having a hollow formed therein, and a reinforcing member formed of a material different from the aluminum material and disposed in the hollow in a non-joined state with the profile, the reinforcing member being disposed so as to brace the profile in a first direction in which a load acts on the profile, the profile being formed in a substantially rectangular ring shape in a cross-sectional view perpendicular to the longitudinal direction and having a first plate portion and a second plate portion opposed to each other in the first direction, the reinforcing member having a first reinforcing plate portion disposed along the first plate portion, a second reinforcing plate portion disposed along the second plate portion, and a wall portion connecting the first reinforcing plate portion and the second reinforcing plate portion, and being formed in a substantially H-shape in a cross-sectional view perpendicular to the longitudinal direction , the first reinforcing plate portion being disposed with a gap on the inner surface of the first plate portion, and the second reinforcing plate portion being disposed with a gap on the inner surface of the second plate portion .

（第一実施形態）
以下、第一実施形態に係るアルミニウム形材の補強構造について、図面に基づいて説明する。図１に示すように、本実施形態に係るアルミニウム形材の補強構造１は、形材１０と、補強部材２０と、を備えている。アルミニウム形材の補強構造１は、例えば建具等の建材に使用される。 First Embodiment
Hereinafter, a reinforcement structure for an aluminum profile according to a first embodiment will be described with reference to the drawings. As shown in Fig. 1, the reinforcement structure 1 for an aluminum profile according to this embodiment includes a profile 10 and a reinforcing member 20. The reinforcement structure 1 for an aluminum profile is used for building materials such as building fixtures.

形材１０は、図１の紙面に直交する方向に延びる長尺部材である。図１の紙面の上下方向をＴ１方向（第一方向）とし、紙面の左右方向をＴ２方向（第二方向）とする。 The profile 10 is a long member that extends in a direction perpendicular to the plane of the paper in FIG. 1. The up-down direction of the paper in FIG. 1 is the T1 direction (first direction), and the left-right direction of the paper is the T2 direction (second direction).

形材１０は、アルミニウム材料によって形成されている。形材１０は、長手方向に直交する断面視で略矩形の環状に形成されている。形材１０の内部には、中空状のホローｓ１が形成されている。ホローｓ１は、形材１０の長手方向の略全長に形成されている。 The profile 10 is made of aluminum material. The profile 10 is formed in a generally rectangular ring shape in a cross section perpendicular to the longitudinal direction. A hollow space s1 is formed inside the profile 10. The hollow space s1 is formed over approximately the entire length of the profile 10 in the longitudinal direction.

形材１０は、第一板部１１と、第二板部１２と、第三板部１３と、第四板部１４と、を有している。 The profile 10 has a first plate portion 11, a second plate portion 12, a third plate portion 13, and a fourth plate portion 14.

第一板部１１及び第二板部１２は、平板状に形成されている。第一板部１１の板面及び第二板部１２の板面は、Ｔ１方向を向いている。第一板部１１と第二板部１２とは、Ｔ１方向に対向して配置されている。 The first plate portion 11 and the second plate portion 12 are formed in a flat plate shape. The plate surface of the first plate portion 11 and the plate surface of the second plate portion 12 face the T1 direction. The first plate portion 11 and the second plate portion 12 are disposed opposite each other in the T1 direction.

第三板部１３及び第四板部１４は、第一板部１１の端部と第二板部１２の端部とを接続している。第三板部１３及び第四板部１４は、平板状に形成されている。第三板部１３の板面及び第四板部１４の板面は、Ｔ２方向を向いている。第三板部１３と第四板部１４は、Ｔ２方向に対向して配置されている。 The third plate portion 13 and the fourth plate portion 14 connect an end of the first plate portion 11 and an end of the second plate portion 12. The third plate portion 13 and the fourth plate portion 14 are formed in a flat plate shape. The plate surface of the third plate portion 13 and the plate surface of the fourth plate portion 14 face the T2 direction. The third plate portion 13 and the fourth plate portion 14 are arranged facing each other in the T2 direction.

第一板部１１の内面には、Ｔ２方向の略中央に第一レール１５が設けられている。第一レール１５は、第一板部１１の長手方向の略全長に設けられている。第一レール１５は、一対の第一リブ（保持部）１５ａを有している。第一リブ１５ａは、第一板部１１から第二板部１２側に延びている。一対の第一リブ１５ａは、Ｔ２方向に間隔をあけて配置されている。一対の第一リブ１５ａ間の距離は、後述する補強部材２０の板厚と略同一または補強部材２０の板厚よりもわずかに長い。 A first rail 15 is provided on the inner surface of the first plate portion 11, approximately in the center in the T2 direction. The first rail 15 is provided over approximately the entire length of the first plate portion 11 in the longitudinal direction. The first rail 15 has a pair of first ribs (retaining portions) 15a. The first ribs 15a extend from the first plate portion 11 toward the second plate portion 12. The pair of first ribs 15a are arranged with a gap in the T2 direction. The distance between the pair of first ribs 15a is approximately the same as or slightly longer than the plate thickness of the reinforcing member 20 described below.

第二板部１２の内面には、Ｔ２方向の略中央に第二レール１６が設けられている。第二レール１６は、第二板部１２の長手方向の略全長に設けられている。第二レール１６は、第一レール１５とＴ１方向に対向して配置されている。第二レール１６は、一対の第二リブ（保持部）１６ａを有している。第二リブ１６ａは、第二板部１２から第一板部１１側に延びている。一対の第二リブ１６ａは、Ｔ２方向に間隔をあけて配置されている。一対の第二リブ１６ａ間の距離は、後述する補強部材２０の板厚と略同一または補強部材２０の板厚よりもわずかに長い。 A second rail 16 is provided on the inner surface of the second plate portion 12, approximately in the center in the T2 direction. The second rail 16 is provided over approximately the entire length of the second plate portion 12 in the longitudinal direction. The second rail 16 is disposed opposite the first rail 15 in the T1 direction. The second rail 16 has a pair of second ribs (retaining portions) 16a. The second ribs 16a extend from the second plate portion 12 toward the first plate portion 11. The pair of second ribs 16a are disposed with a gap in the T2 direction. The distance between the pair of second ribs 16a is approximately the same as or slightly longer than the plate thickness of the reinforcing member 20 described below.

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 disposed 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 reinforcing member 20 is provided over substantially the entire length of the profile 10 in the longitudinal direction. The shape of the reinforcing member 20 is not limited to a flat plate shape, and may be formed from a square tube or the like that is formed in a rectangular shape in a cross section perpendicular to the longitudinal direction, and may be configured to be disposed between a pair of first ribs 15a and a pair of second ribs 16a by increasing the distance 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 that forms the profile 10. The reinforcing member 20 is made of a material that is more rigid than aluminum. The reinforcing member 20 is made of, for example, CFRP (Carbon Fiber Reinforced Plastics) or steel.

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 not joined to the profile 10. The reinforcing member 20 is not chemically bonded to the profile 10 with adhesive or the like, nor is it mechanically fastened to the profile 10 with double-sided tape or 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 a pair of first ribs 15a. The other end 20a of the reinforcing member 20 is held by the second rail 16 and sandwiched between a 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 20a of the reinforcing member 20 is in contact with the first plate portion 11 and the second plate portion 12, or is positioned with a small gap between them.

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。 When in use, loads such as external forces act on the shaped member 10 in the direction T1. When used in the horizontal frame or stile of a fixture with the longitudinal direction of the shaped member 10 facing the width direction of the fixture, a load acts in the first direction T1 due to gravity, indoor/outdoor air pressure, etc. When used in the vertical frame or stile of a fixture with the longitudinal direction of the shaped member 10 facing up and down, a load acts in the first direction T1 due to the opening and closing of a paper screen, indoor/outdoor air pressure, etc.

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 20a of the reinforcing member 20 abuts against the first plate portion 11 and the second plate portion 12 and braces them in the T1 direction, thereby suppressing deformation of the profile 10, such as bending of the first plate portion 11 and the second plate portion 12.

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 placing the reinforcing member 20 inside the profile 10, it is sufficient to simply insert the reinforcing member 20 from its longitudinal end between the pair of first ribs 15a and 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 aluminum profile reinforcement structure 1 configured in this manner, when a load acts on the profile 10 in the T1 direction, the reinforcement member 20 braces itself in the T1 direction to resist the load. Because the reinforcement member 20 is disposed in the hollow of the profile 10, there is no need to increase the profile 10 itself, such as the thickness of the profile 10, and the size of the profile 10 can be reduced.

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 reinforcing member 20 is formed from a material different from the aluminum material forming the profile 10, and there may be a difference in thermal expansion coefficient between the reinforcing member 20 and the profile 10. Since the reinforcing member 20 is not joined to the profile 10, deformation of either the reinforcing member 20 or the profile 10 due to temperature change is prevented from affecting the deformation of the other.

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 aluminum profile reinforcement structure 1, a pair of first ribs 15a and a pair of second ribs 16a that hold the reinforcement member 20 are provided in the hollow s1 of the profile 10. This prevents the reinforcement member 20 from rattling or shifting out of position.

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 aluminum profile reinforcement structure 1, the reinforcement member 20 is held by a pair of first ribs 15a and a pair of second ribs 16a spaced apart in the T2 direction on the profile 10. This restricts movement of the reinforcement 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, a reinforcement structure for an aluminum profile according to a second embodiment will be described mainly with reference to Fig. 2. In the description of the embodiment shown below, the same members as those described above are given the same reference numerals, 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 aluminum profile reinforcement structure 1A, the reinforcement member 20 is held by a pair of attachments (holding portions) 30. The attachments 30 are arranged in the hollow s1 of the profile 10. The attachments 30 are arranged on both sides of the reinforcement member 20 in the T2 direction. The pair of attachments 30 are arranged symmetrically about 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. Multiple attachments 30 are arranged at intervals along the longitudinal direction of the profile 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 generally C-shape in a cross section perpendicular to the longitudinal direction. The attachment 30 has a retaining 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 retaining wall portion 31 is formed in a flat plate shape. The plate surface of the retaining wall portion 31 faces the T2 direction. The retaining wall portion 31 is arranged along the surface 20b of the reinforcing member 20 facing the T2 direction. One end portion 31a of the retaining wall portion 31 in the T2 direction does not reach the first plate portion 11. The other end portion 31a of the retaining 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 folded wall portion 32 extends from both ends 31a of the retaining wall portion 31 in the T1 direction in a direction away from the surface 20b of the reinforcing member 20. The ends 32a of the folded wall portion 32 abut against the third plate portion 13 and the fourth plate portion 14 or are arranged with a small 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 retaining wall portion 31 is adhered to the reinforcing member 20 using a sponge-like double-sided tape 36. The retaining wall portion 31 may be adhered to the reinforcing member 20 using an adhesive or a non-sponge-like double-sided tape. The reinforcing member 20 is sandwiched between the attachments 30 on 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 aluminum profile reinforcement structure 1A configured in this manner, when a load acts on the profile 10 in the T1 direction, the reinforcement member 20 braces itself in the T1 direction to resist the load. Because the reinforcement member 20 is disposed in the hollow of the profile 10, there is no need to increase the profile 10 itself, such as the thickness of the profile 10, and the size of the profile 10 can be reduced.

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 reinforcement structure 1A, the reinforcing member 20 is made of a material different from the aluminum material that forms the profile 10, and there may be a difference in thermal expansion coefficient between the reinforcing member 20 and the profile 10. Since the reinforcing member 20 is not joined to the profile 10, deformation of either the reinforcing member 20 or the profile 10 due to temperature changes is prevented from affecting the deformation of the other.

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 aluminum profile reinforcement structure 1A, the reinforcement member 20 is sandwiched and held by the attachments 30 on both sides in the T2 direction. This restricts the movement of the reinforcement member 20 in the T2 direction. The attachments 30 can be separate members from the profile 10, so there is no need to use a dedicated profile.

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 aluminum profile reinforcement structure 1A, the attachment 30 and the reinforcement member 20 are fixed with a sponge-like double-sided tape 36. This allows the vibrations generated in the profile 10 to be absorbed by the sponge-like double-sided tape 36, suppressing rattling noises.

（第三実施形態）
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, a reinforcement structure for an aluminum profile according to a third embodiment will be described mainly with reference to Fig. 3. As shown in Fig. 3, the reinforcement member 20B is arranged in the hollow s1 so as to be able to stand on its own. The reinforcement member 20B is formed in a substantially rectangular shape in a cross section perpendicular to the longitudinal direction of the profile 10. The reinforcement member 20B is arranged over substantially the entire length of the profile 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 20B 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 opposite 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 small 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 small gap therebetween.

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 opposite 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 small 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 small gap therebetween.

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 profile 10 in the T1 and T2 directions, the reinforcing member 20B braces itself 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。 When a load acts on the aluminum profile 1B in the T1 direction, the reinforcing member 20B braces itself in the T1 direction to resist the load. Because the reinforcing member 20B is placed in the hollow of the profile 10, there is no need to increase the thickness of the profile 10 itself, and the size of the profile 10 can be reduced.

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 aluminum profile reinforcement structure 1B, the reinforcing member 20B is made of a material different from the aluminum material that forms the profile 10, and there may be a difference in thermal expansion coefficient between the reinforcing member 20B and the profile 10. Since the reinforcing member 20B is not joined to the profile 10, deformation of either the reinforcing member 20B or the profile 10 due to temperature changes is prevented from affecting the deformation of the other.

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 aluminum profile reinforcement structure 1B, the reinforcement member 20B itself is hollow and can stand on its own. By placing the reinforcement member 20B in the hollow, the reinforcement member 20B reinforces the profile 10, making for a simple structure.

上述した実施の形態において示した各構成部材の諸形状や組み合わせ等は一例であって、本開示の主旨から逸脱しない範囲において設計要求等に基づき種々変更可能である。 The shapes and combinations of the components shown in the above-described embodiment are merely examples, and may be modified in various ways based on design requirements, etc., without departing from the spirit of this disclosure.

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 act on the profile 10 in both the T1 and T2 directions, rails like the first rail 15 may be provided on the third plate portion 13 and the fourth plate portion 14, so that the reinforcing member has a cross shape in a cross section perpendicular 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 section 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 section perpendicular to the longitudinal direction of the shaped member 10. The reinforcing member 20B may not have the third reinforcing plate portion 23 and the fourth reinforcing plate portion 24, and may have a wall portion connecting 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. The reinforcing member 20B may be formed in a substantially triangular shape in a cross section perpendicular to the longitudinal direction of the shaped member 10. One side of the triangle may abut against either the first plate portion 11 or the second plate portion 12, and the apex opposite to the one side of the triangle may abut against the other of the first plate portion 11 and the second plate portion 12.
