Description

この発明は、構造用部材として使用される型鋼等としての必要な強度を保持し、かつ化粧材として構造用部材の表面を必要な平滑な状態に仕上げ、豪華、高品質、高級・重量感の外観を有する複合化粧構造用部材及びその製造方法に関する。   This invention retains the required strength as a structural steel used as a structural member, and finishes the surface of the structural member as a decorative material in the required smooth state, giving it a luxurious, high quality, high quality and heavy feeling. The present invention relates to a composite decorative structural member having an appearance and a method for producing the same.

近年、近代ホテル、豪華集合建築物、高級マンション、地下商店街等の豪華な雰囲気と高級・重量感を必要とする建築物等のドアーや窓枠、エレベータの出入り口、壁のコーナ縁材等の材料として、ステンレス鋼（ＳＵＳ）、アルミ合金、チタン合金等を材料とする金属製の建材が広く利用されている。これらの建材は、建築物の構造用部材（強度部材）ではなく、ドアー、窓枠、エレベータ等の装置の構造用部材（強度部材）でもなく、ドアー、窓枠、壁と壁の見切り材等の縁材として利用する場合は、補強材であり、かつ外観が美しい意匠材として利用される。   In recent years, doors and window frames, elevator doorways, corner edges of walls, etc. for luxury hotels such as modern hotels, luxury apartment buildings, luxury condominiums, underground shopping streets, etc. As a material, metal building materials made of stainless steel (SUS), aluminum alloy, titanium alloy or the like are widely used. These building materials are not structural members (strength members) for buildings, but are not structural members (strength members) for devices such as doors, window frames, elevators, etc., but are doors, window frames, parting materials for walls and walls, etc. When used as an edge material, it is used as a design material that is a reinforcing material and has a beautiful appearance.

これらの建材以外に建築物の構造強度を支持する構造用部材として、Ｈ型鋼、チャンネル型鋼、アングル材等の所謂型鋼と呼ばれる部材が多く使用されているが、一般にこれらの構造用部材は壁の表面材の中に配置され、建物等では外観上殆ど見ることはない。このため、構造用部材は上記補強材に施される平滑な表面仕上げや模様のような特別な仕上げ加工は不要であり、型鋼として圧延、押出し、或いは鋳造等の加工により大量生産された材料をその施工現場に要求される圧縮・引張り・剪断等の強度、硬度、延性、弾性係数、温度係数等の機械的性質や形状、長さ、幅などの諸寸法精度などが適合するものであればよい。   In addition to these building materials, as structural members for supporting the structural strength of the building, members called so-called steel plates such as H-shaped steel, channel steel, and angle materials are often used. Generally, these structural members are made of walls. It is arranged in the surface material and is hardly seen on the exterior in buildings. For this reason, the structural member does not require a special finishing process such as a smooth surface finish or pattern applied to the reinforcing material, and a material that is mass-produced by a process such as rolling, extrusion, or casting is used as a mold steel. Any mechanical properties such as compression, tension, and shear required for the construction site, hardness, ductility, elastic modulus, temperature coefficient, and other dimensional accuracy such as shape, length, and width are compatible. Good.

一般に構造用部材の型鋼として量産されるステンレス型鋼は、ＪＩＳ規格で定められた範囲内の機械特性、形状、材質のステンレス型鋼（例えばＳＵＳ３０４）が使用され、熱間圧延処理で所定形状の型鋼として形成される。このように量産されるステンレス型鋼は、一般に熱間圧延で成形されるため、その表面の仕上げ状態が粗い。しかし、ステンレス型鋼は、錆に強く強度も一般の構造用部材と同等の強度を有するという特性から、構造用部材としても広く使用されている。   Generally, stainless steel molds that are mass-produced as structural steels for structural members use stainless steel molds (for example, SUS304) that have mechanical properties, shapes, and materials within the range defined by JIS standards. It is formed. Since the stainless steel that is mass-produced in this way is generally formed by hot rolling, the surface finish is rough. However, stainless steel is widely used as a structural member because it is resistant to rust and has the same strength as a general structural member.

一方、建材のように使用される金属材料が、例えばアルミサッシやステンレス製サッシ等を使用した建材のように、使用される金属材料が数ミリ程度の薄い合金製の金属材料の場合、使用する対象部位が窓やドアーの縁材として利用することを前提としている。そして、このような薄い合金製の金属材料、特にステンレス材は、一般に冷間圧延で製造されるため、上記構造用部材としてのステンレス型鋼よりもその表面状態が平滑であり、高度の表面仕上げを要求されない一般的な水準では、さらに表面加工を施すことなくそのままでも化粧材として利用できる。   On the other hand, if the metal material used as a building material is a thin alloy metal material of about several millimeters, such as a building material using an aluminum sash or a stainless steel sash, use it. It is assumed that the target part will be used as an edge material for windows and doors. And since such a thin alloy metal material, especially stainless steel, is generally manufactured by cold rolling, its surface state is smoother than stainless steel as the structural member, and it has a high surface finish. At a general level that is not required, it can be used as it is without any further surface treatment.

このような薄い金属材料を利用した建材の例として、特許文献１の「複合アルミ建材」が公知である。この複合アルミ建材は、木製の角材と同様に扱えるアルミ建材を提案したものである。この複合アルミ建材は、断面矩形状の長尺木製心材の外周に木材用鋸で切断可能な薄板アルミ材を用いて矩形断面の外装材を形成し、その中空部に木材を挿入したものであって、一般の木材製の角材と同等のものとして使用される。
実開平５−３０３１４号公報 As an example of a building material using such a thin metal material, “composite aluminum building material” of Patent Document 1 is known. This composite aluminum building material is an aluminum building material that can be handled in the same way as a wooden square. This composite aluminum building material is formed by forming a rectangular cross-section exterior material using a thin aluminum plate that can be cut with a wood saw on the outer periphery of a long wooden core material having a rectangular cross-section, and inserting wood into the hollow portion. In addition, it is used as an equivalent to ordinary wood timber.

ところで、上述したように、一般に構造用部材の型鋼として量産されるステンレス型鋼は、熱間圧延処理で所定形状の型鋼として形成されるため、その表面仕上げ状態が粗であり、使用する場所によっては構造用部材を外壁から露出した場所に使用する場合があり、この場合は構造用部材としての強度と、材料表面の平滑度が高い表面仕上げや模様を施された外観に優れた意匠性の両方の特性を有する材料が要求される。しかし、ステンレス型鋼の表面処理が十分でないため、実際には研磨装置で表面を研磨して表面粗度を必要な程度に調整して対応している。   By the way, as described above, stainless steel molds that are generally mass-produced as structural steels for structural members are formed as hot-rolled steel molds with a predetermined shape, so that the surface finish is rough, and depending on where they are used In some cases, structural members may be used where they are exposed from the outer wall. In this case, both the strength as a structural member and the design with excellent surface finish and patterned appearance with high smoothness of the material surface A material having the following characteristics is required. However, since the surface treatment of the stainless steel is not sufficient, the surface roughness is actually adjusted by a polishing apparatus to adjust the surface roughness to a necessary level.

このような表面処理を必要とする場所や施設に使用される構造用部材としてのステンレス型鋼では、その場所や施設に適合するようにステンレス型鋼の表面を研磨する処理に多大な労力とコストが掛かり、ステンレス型鋼そのものの材料費の高騰のため、ますます利用が困難となっている。また、Ｈ型鋼、チャンネル型鋼、アングル材のような中実断面の構造用部材のいずれにも、その中間位置に曲がり部（アール）が設けられており、この曲がり部の研磨は、平板面の処理とは異なり特別な処理を必要とし、加工処理が一層困難である。従って、その表面処理を全周に亘り均一に処理する方法が種々試みられていたが、有効な方法は提案されていない。   In stainless steel as a structural member used in places and facilities that require such surface treatment, a great amount of labor and cost are required to polish the surface of the stainless steel so as to be suitable for the place and facility. However, the use of stainless steel is becoming increasingly difficult due to soaring material costs. Further, any of the structural members having a solid cross section such as H-shaped steel, channel-shaped steel, and angle members is provided with a bent portion (R) at an intermediate position thereof, and polishing of the bent portion is performed on a flat plate surface. Unlike processing, it requires special processing and is more difficult to process. Therefore, various methods have been tried to uniformly treat the entire surface of the surface, but no effective method has been proposed.

この発明は、上記の問題に留意して、量産された各種ステンレス型鋼等の構造用部材と同等またはそれ以上の強度を有し、かつ外観はステンレス鋼等の合金材に表面加工を施した以上の荘厳で、高級感、重量感、高品質感のある美観、意匠性を有する中実断面の複合化粧構造用部材及びその製造方法を提供することを課題とする。   In consideration of the above problems, the present invention has a strength equal to or higher than that of structural members such as various stainless steels that are mass-produced, and has an appearance that is obtained by subjecting an alloy material such as stainless steel to surface processing. It is an object of the present invention to provide a composite decorative structural member having a solid cross section having a solemn, high-class feeling, weight feeling, high-quality aesthetics, and design, and a method for producing the same.

この発明は、上記の課題を解決する手段として、各種の型鋼を含む鉄系の構造用部材を中心に配置し、その外周を化粧材としてステンレス鋼等の複数枚の薄板鋼板で囲むようにして中実断面を形成し、薄板鋼板の外面には予め必要な表面処理及び/又は曲げ加工を施し、かつそれぞれの薄板鋼板は複数個所で接合され、接合箇所に施された糸面処理で必要なエッジを形成した複合化粧構造用部材の構成としたのである。   As a means for solving the above-mentioned problems, the present invention is arranged in such a manner that an iron-based structural member including various types of steel is centered and the outer periphery thereof is surrounded by a plurality of thin steel plates such as stainless steel as a decorative material. A cross section is formed, and the outer surface of the thin steel plate is preliminarily subjected to necessary surface treatment and / or bending, and each thin steel plate is joined at a plurality of locations, and the necessary edge is obtained by the yarn surface treatment applied to the joining location. It was set as the structure of the formed composite decorative structure member.

上記の構成としたこの発明の複合化粧構造用部材は、中心に構造用部材を配置し、その外周に薄板鋼板を密着して接合、一体化したものである。そして、その用途として構造用部材を目的とし、かつ意匠部材として使用されることを想定したものである。このため、部材の断面が中実断面で、かつ外観は量産されるステンレス型鋼のように表面状態が粗な状態ではなく、設置される場所に必要な荘厳で、高級感、重量感、高品質感のある美感を有する。   The composite decorative structural member of the present invention having the above-described configuration is obtained by arranging a structural member at the center and bonding and integrating a thin steel plate on the outer periphery thereof. And it assumes that it is used as a design member for the purpose of the structural member as the use. For this reason, the cross section of the member is a solid cross section, and the appearance is not a rough state like the mass-produced stainless steel, but it is a majestic necessary for the place where it is installed, high quality, heavy feeling, high quality Has a sense of beauty.

上記の複合化粧構造用部材を製造する方法として、中心に配置される各種の型鋼を含む鉄系の構造用部材の外形形状に適合するように、予め所定幅、長さのステンレス鋼等の複数枚の薄板鋼板のそれぞれに、必要とされる表面処理及び/又は曲げ加工部を平板状で施し、そのうちのいくつかの薄板鋼板の囲むスペース内に構造用部材を挿入した後、他の薄板鋼板で全周を囲み、それぞれの薄板鋼板と構造用部材が接合される面間には予めいずれかの部材又は両部材の表面に接合、一体化するための接合手段を介在させて密着、接合して複合化粧構造用部材を形成するようにした複合化粧構造用部材の製造方法を採用することが出来る。   As a method of manufacturing the above-mentioned composite decorative structural member, a plurality of stainless steel or the like having a predetermined width and length in advance so as to conform to the outer shape of an iron-based structural member including various types of steel plates arranged in the center. Each of the thin steel plates is subjected to the necessary surface treatment and / or bending process in a flat plate shape, and after inserting structural members into the space surrounded by some of the thin steel plates, other thin steel plates The entire circumference of the steel sheet and the structural member are joined with each other in advance, and in close contact with each other or by joining means for integrating them on the surfaces of the two members. Thus, a method for producing a composite decorative structure member that forms a composite decorative structure member can be employed.

上記複合化粧構造用部材の製造方法によれば、外周に配置される薄板鋼板には、接合される前に平板状の段階で、一体化後は外側となる面に対して予め必要な表面仕上げ加工を十分に施すことが出来、屈曲、曲げ加工をする処理を精度よく仕上げることにより、従来の量産されたステンレス型鋼等の構造用部材を、意匠性が要求される場所に使用する際に要求される表面仕上げ加工を型鋼に対してではなく、薄板鋼板に平板状で施すことが出来る。このため、表面仕上げの作業が容易となり、表面仕上げに掛かる労力が低減され、かつ表面仕上げ加工の精度が向上する。又、強度はステンレス型鋼のような構造用部材と同等またはそれ以上の強度を有し、従って意匠性に優れた美しい外観の複合化粧構造用部材が得られる。   According to the method for manufacturing a composite decorative structural member, a thin steel plate disposed on the outer periphery is in a flat stage before being joined, and a surface finish required in advance for the outer surface after integration. Required when using conventional mass-produced structural members, such as stainless steel, in places where design is required, by providing sufficient processing and finishing the bending and bending processes with high precision. The surface finishing that is performed can be applied to the thin steel plate in a flat plate shape, not to the die steel. For this reason, the surface finishing work is facilitated, the labor required for the surface finishing is reduced, and the accuracy of the surface finishing process is improved. Further, the composite decorative structural member having a beautiful appearance and excellent in design is obtained because the strength is equal to or higher than that of a structural member such as stainless steel.

この発明の複合化粧構造用部材は、構造用部材を中心に配置し、その外周を化粧材としてステンレス鋼等の複数枚の薄板鋼板で囲むようにして中実断面を形成し、薄板鋼板の外面には予め必要な表面処理及び/又は曲げ加工を施し、かつそれぞれの薄板鋼板は複数個所で接合され、接合箇所に施された糸面処理で必要なエッジを形成したから、量産された各種ステンレス型鋼等の構造用部材と同等またはそれ以上の強度を有し、かつ外観はステンレス鋼等の合金材に表面加工を施した以上の荘厳で、高級感、重量感、高品質感のある美観、意匠性を有する中実断面の複合化粧構造用部材を得ることができるという利点がある。   The composite decorative structural member of the present invention is arranged around the structural member, and the outer periphery of the composite decorative structural member is surrounded by a plurality of thin steel plates such as stainless steel as a decorative material to form a solid cross section. The necessary surface treatment and / or bending process is performed in advance, and each thin steel plate is joined at a plurality of locations, and the necessary edge is formed by the yarn surface treatment applied to the joining location. It has a strength equivalent to or better than that of structural members, and the appearance is more majestic than the surface treatment of an alloy material such as stainless steel, and it has a sense of quality, weight, high quality, and design. There is an advantage that a composite cross-section structural member having a solid cross section can be obtained.

また、上記複合化粧構造用部材の製造方法によれば、平板状の段階で一体化後は外側となる面に対して予め必要な表面仕上げ加工を十分に施すことが出来、屈曲、曲げ加工をする処理を精度よく仕上げることにより、従来のステンレス型鋼に要求される表面仕上げ加工を平板状で施すことが出来る。このため、表面仕上げに掛かる労力を低減でき、かつ表面仕上げ加工の精度が向上し、加工の際の労力を低減し、かつ経済的なコストで製造することが出来るという効果が得られる。   In addition, according to the method for manufacturing a composite decorative structural member, a necessary surface finishing process can be sufficiently performed in advance on the outer surface after integration in a flat plate stage, and bending and bending processes can be performed. By finishing the processing to be performed with high precision, the surface finishing required for conventional stainless steel can be performed in a flat plate shape. For this reason, it is possible to reduce the labor required for the surface finishing, improve the accuracy of the surface finishing process, reduce the labor during the process, and obtain an effect that can be manufactured at an economical cost.

以下、この発明の実施形態について図面を参照して説明する。図１は第１実施形態のアングル材形状の複合化粧構造用部材Ａ_１の（ａ）外観斜視図、（ｂ）（ａ）図のＢ−Ｂ断面図、（ｃ）（ｂ）図の丸印Ｃの部分の拡大断面図である。図示のように、この複合化粧構造用部材Ａ_１は、アングル材形状の型鋼を含む鉄系の構造用部材１（例えばＳＳ材のような軟鋼、機械構造用炭素鋼ＳＣ、鋳鉄ＦＣ等）を中心とし、その外周を化粧材としてステンレス鋼製（図示の例ではＳＵＳ３０４）の複数枚の薄板鋼鈑２ａ、２ｂで囲むように配置して形成している。 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1A is a perspective view of an angle member-shaped composite decorative structure member A1 according to the _first embodiment, FIG. 1B is a cross-sectional view taken along line B-B in FIG. 1A, and FIG. It is an expanded sectional view of the portion of mark C. As shown, the composite decorative structural members A ₁ is (mild steel such as SS material, carbon steel for machine structural use SC, cast iron FC etc.) angle member structural member of iron system including a mold steel shape 1 The outer periphery is arranged so as to be surrounded by a plurality of thin steel plates 2a and 2b made of stainless steel (SUS304 in the illustrated example) as a decorative material.

ステンレス製の薄板鋼板２ａ、２ｂは、冷間圧延処理により得られるものであり、原材料の段階で熱間圧延加工、引抜加工、押出加工で得られる表面仕上げよりその円滑度が高く、滑らかな外観に優れた材料が使用されており、その外面には、さらに必要に応じて長さ、幅方向に予め必要な表面処理及び/又は曲げ加工を施し、複合化粧構造用部材Ａ_１の意匠材として適合する材料が使用される。また、実施形態の例では板厚が１．５ｍｍである。この薄板鋼板２ａ、２ｂの板厚は上記厚さに限定されないが、使用される用途に応じて１〜３ｍｍ程度の薄板状のものを用いる。 Stainless steel sheets 2a and 2b made of stainless steel are obtained by cold rolling, and are smoother and smoother than the surface finishes obtained by hot rolling, drawing and extrusion at the raw material stage. excellent materials have been used, the outer surface thereof, further if necessary by length, previously subjected to necessary surface treatment and / or bending in the width direction, as a design member of the composite decorative structural members a ₁ A compatible material is used. In the example of the embodiment, the plate thickness is 1.5 mm. The plate thickness of the thin steel plates 2a and 2b is not limited to the above thickness, but a thin plate of about 1 to 3 mm is used depending on the application to be used.

なお、上記複合化粧構造用部材Ａ_１の意匠材としては、ステンレス鋼製の薄板以外にも、例えばアルミ合金製等の各種合金材の薄板を使用してもよい。また、鉄系の構造用部材１は、使用される場所、施設等に必要とされる圧縮・引張・剪断強度等の機械的特性で、従来のステンレス型鋼等の構造部材と同等またはそれ以上の強度を有しているものとする。それぞれの薄板鋼板２ａ、２ｂは、構造用部材１を囲むのに適合する形状に折り曲げ、断面の複数個所でその長さ方向に沿って接合され、それぞれの接合箇所に施された糸面処理で必要なエッジ部を形成している。 As the design materials of the composite decorative structural members A _1, in addition to stainless steel sheet may also be used, for example, thin plate of various alloy material aluminum alloy or the like. In addition, the iron-based structural member 1 has mechanical characteristics such as compression, tensile, and shear strength required for the place and facility where it is used, and is equivalent to or higher than that of a conventional structural member such as stainless steel. It shall have strength. Each of the thin steel plates 2a and 2b is bent into a shape suitable to enclose the structural member 1, and is joined along the length direction at a plurality of sections of the cross section, and the yarn surface treatment applied to each joining place Necessary edge portions are formed.

曲げ加工部の一例として設けられた３はシカル加工部であり、予め平板状で複合化粧構造用部材Ａ_１のコーナ部となる位置の内側に、シカル加工装置のカッターにより溝を形成し、それぞれのシカル加工部３で薄板鋼板２ａ、２ｂを折り曲げ、その外側のコーナにエッジ部が形成されている。４は薄板鋼板２ａ、２ｂのそれぞれを端部２ｅ、２ｅの突合せ部で当接した後に、そのエッジ部に糸面加工を施した糸面加工部である。５は金属同士を接合できる高強度、高接着性の金属用接着剤であり、接合手段の一例として用いられている。 3 provided as an example of a bending part is a shir processing part, and a groove is formed in advance by a cutter of a shikal processing device inside a flat plate-shaped corner portion of the composite decorative structure member A _1. The thin plate steel plates 2a and 2b are bent at the SiCal processing portion 3, and an edge portion is formed at the outer corner. Reference numeral 4 denotes a yarn surface processed portion in which each of the thin steel plates 2a and 2b is brought into contact with the butted portion of the end portions 2e and 2e, and then the edge surface is subjected to thread surface processing. Reference numeral 5 denotes a high-strength, high-adhesive metal adhesive capable of joining metals together, and is used as an example of a joining means.

薄板鋼板２ａ、２ｂを鉄系の構造用部材１の外周に密着させる前に、それぞれの薄板鋼板２ａ、２ｂの端部２ｅは、正確に４５度の傾斜端面状に切断されたものを使用し、その端部２ｅ、２ｅ同士を突き合わせて構造用部材１に密着させ、一体化する。その製造方法については後で説明する。また、鉄系の構造用部材１の外周には予め、防錆塗料が塗布されているか、或いは亜鉛メッキ処理等の防錆処理が施され、薄板鋼板２ａ、２ｂを密着、一体化した後に内部の空隙から侵入する空気により構造用部材１に錆が生じないように処理がされていなければならない。   Before the thin steel plates 2a and 2b are brought into close contact with the outer periphery of the iron-based structural member 1, the end portions 2e of the respective thin steel plates 2a and 2b are precisely cut into an inclined end surface of 45 degrees. The end portions 2e and 2e are brought into contact with each other and brought into close contact with the structural member 1 to be integrated. The manufacturing method will be described later. Further, the outer periphery of the iron-based structural member 1 is coated with a rust-preventing paint in advance, or is subjected to a rust-proofing treatment such as galvanization, and the thin steel plates 2a and 2b are brought into close contact with each other and integrated. The structure member 1 must be treated so that rust does not occur due to air entering from the gaps.

上記薄板鋼板２ａ、２ｂの表面に施される表面処理は、例えば鏡面、発色、エッチング、ブラスト、バイブレーション等の仕上げ、或いはこれらの各種表面仕上げを混合配置したものなど各種の表面仕上げがあり、そのいずれの表面仕上げのものを使用してもよい。ただし、鏡面仕上げの場合には酸を含む特殊な研磨剤が使用され、発色、ブラスト、バイブレーション仕上げなどの場合は、それぞれのケースに応じた研磨処理装置（バフ研磨機、ディスク研磨機等）によりその必要な研磨処理の内容に応じて研磨される。   The surface treatment applied to the surfaces of the thin steel plates 2a and 2b has various surface finishes such as mirror finish, coloring, etching, blasting, vibration finishing, etc., or a mixture of these various surface finishes. Any surface finish may be used. However, in the case of mirror finish, a special abrasive containing acid is used, and in the case of color development, blasting, vibration finishing, etc., use a polishing processing device (buffing machine, disk polishing machine, etc.) according to each case. Polishing is performed according to the content of the necessary polishing treatment.

上記複合化粧構造用部材Ａ_１の薄板鋼板２ａ、２ｂにシカル加工部３を施されたエッジ部の外面は、中実断面のステンレス型鋼等のエッジ部に要求される場合と同等な表面状態の条件として、そのエッジ部に触れると手に傷が付くほどの鋭いエッジではないが、豪華、高品質、高級、重量感のある材料として十分な外観を付与するに必要な程度に角のあるエッジ状でなければならない。エッジ部に大きな丸みが付いた場合は、上述した外観上で必要な質感が低下するからである。 The composite decorative structural members A ₁ of thin steel plate 2a, the outer surface of scolding processing portion 3 subjected edge portion in 2b, in the same surface state as that required for the edge portion of the stainless steel type, such as steel of solid cross section As a condition, it is not a sharp edge that touches the edge when touching the edge, but an edge that has a corner to the extent necessary to give a sufficient appearance as a luxurious, high-quality, high-grade, heavy material. Must be in shape. This is because when the edge portion is greatly rounded, the texture required for the above-described appearance is deteriorated.

上記薄板鋼板２ａ、２ｂの接合端は、互いに正確に４５度に切断したものを用いることを前提としているが、当接する端部２ｅ、２ｅの加工が必ずしも正確に４５度の傾斜角度に処理されているとは限らず、実際には図２の（ａ）図、（ｂ）図の（イ）に示すように、外側に端部２ｅ、２ｅがギャップｇだけ互いに開いている場合と、内側にギャップｇだけ開いている場合とがある。しかし、薄板鋼板２ａ、２ｂは板厚が薄いため、このギャップｇがあっても、プレス装置等の治具で互いに直角方向に押し付けてこのギャップｇを潰し、強制的に図２の（ロ）図に示すように、特に外側の開きを押し潰して接合する。   The joining ends of the thin steel plates 2a and 2b are premised on the use of those cut at exactly 45 degrees from each other. However, the processing of the end portions 2e and 2e that are in contact with each other is always accurately processed at an inclination angle of 45 degrees. In fact, as shown in FIGS. 2 (a) and 2 (b), the end portions 2e and 2e are opened to the outside by a gap g, and the inner side In some cases, the gap g is open. However, since the thin steel plates 2a and 2b are thin, even if this gap g exists, the gap g is crushed by pressing the gaps g with each other by a jig such as a pressing device, forcibly, as shown in FIG. As shown in the figure, the outer opening is particularly crushed and joined.

このとき、外側に開いた隙間ｄは、目視で隙間があることを視認出来ない程の極僅かでなければならない。上記許容範囲内に薄板鋼板２ａ、２ｂを隙間ｄに互いに押し付けた状態で、この隙間を保持するために、接合端にはまずスポット溶接を複合化粧構造用部材Ａ_１の長手方向に適宜の間隔で施す。その後、隙間ｄを保持した状態で、接合端の全長に亘る連続溶接を施す。そして、グラインダ等の研磨手段でこの接合端の外面に糸面加工を施す。 At this time, the gap d opened to the outside must be so small that it cannot be visually recognized that there is a gap. Thin steel plate 2a within the allowable range, 2b in a state in which were pressed together in the gap d, appropriate space to hold the gap, the first spot welding the joint end in the longitudinal direction of the composite decorative structural members A ₁ Apply with. Thereafter, continuous welding is performed over the entire length of the joint end while the gap d is maintained. Then, the yarn surface is processed on the outer surface of the joining end by a grinding means such as a grinder.

この処理により形成される糸面加工部４は、シカル加工部３と同様に、接触したときに手に傷が生じるほどの鋭い角状ではなく、かつ目視では鋭角状でなければならない。しかし、さらに仕上げ加工後の糸面の表面状態が既に予め薄板鋼板２ａ、２ｂに加工が施された表面状態に連続する表面となるようにエッジ加工が行われる。外観が荘厳で高級感、重量感、高品質感を有する複合化粧構造用部材とするためである。   The thread surface processing portion 4 formed by this processing is not in the form of a sharp corner so as to cause scratches on the hand when contacted, and it must be in the form of an acute angle by visual observation. However, the edge processing is performed so that the surface state of the yarn surface after finishing further becomes a surface continuous with the surface state that has already been processed on the thin steel plates 2a and 2b. This is because the appearance is majestic and a composite decorative structure member having a sense of quality, weight, and high quality is obtained.

なお、この複合化粧構造用部材Ａ_１は、構造用部材１の外周に薄板鋼板２ａ、２ｂを密着、接合して一体化させたものであるから、構造用部材１に対して定められたＪＩＳ規定の型鋼の寸法規格の外形寸法より薄板鋼板２ａ、２ｂの板圧分だけ幅、厚さが大きくなるため、設計上はその寸法差を考慮して設計する必要がある。しかし、設計上必要な強度は薄板鋼板２ａ、２ｂの板厚を除いた構造用部材１の材質、形状、機械特性により得ることが出来る。 Incidentally, JIS composite decorative structural members A ₁ is the outer circumference thin steel plate 2a of the structural member 1, adhesion and 2b, because those were integrated by bonding, defined with respect to structural member 1 Since the width and thickness of the thin steel plates 2a and 2b are larger than the outer dimensions of the stipulated dimensional standard of the standard steel plate, the design needs to be designed in consideration of the dimensional difference. However, the strength required for design can be obtained by the material, shape, and mechanical characteristics of the structural member 1 excluding the thickness of the thin steel plates 2a and 2b.

接合手段としての金属用接着剤５は、金属同士を接着できるものであれば、どのような種類の接着剤でも良いが、一般的にはエポキシ系、シアノアクリレート系の樹脂接着剤が使用される。金属用接着剤の特殊な例として、例えば特開平６−１３６３４２号公報、特開平７−２８６１５９号公報、特開平１１−１１２５５４号公報等に記載の接着剤を使用することも出来る。一般に、金属用接着剤は衝撃に弱いとされているが、構造用部材１に対してその外周に付着された薄板鋼板２ａ、２ｂが、外力により衝撃を加えられても、剥がれ落ちないのに十分な接着強度を有する接着剤でなければならない。   The metal adhesive 5 as a joining means may be any type of adhesive as long as it can bond metals to each other, but generally an epoxy-based or cyanoacrylate-based resin adhesive is used. . As special examples of metal adhesives, for example, the adhesives described in JP-A-6-136342, JP-A-7-286159, JP-A-11-112554, and the like can be used. In general, metal adhesives are considered to be vulnerable to impact, but the thin steel plates 2a and 2b attached to the outer periphery of the structural member 1 are not peeled off even when impact is applied by external force. The adhesive must have sufficient adhesive strength.

上記複合化粧構造用部材Ａ_１の製造は、次のような手順で行われる。まず、図３Ａの（ａ）図に示すように、まず幅方向が所定寸法（型鋼の外周面に対応する幅）に切断された所定長さ（４〜６ｍ）のステンレス製の２枚の薄板鋼板２ａ、２ｂをそれぞれ用意する。薄板鋼板２ａ、２ｂの両端の端部２ｅ、２ｅは予めそれぞれ４５度に切断しているものとする。そして、図３Ａの（ｂ）図に示すように、薄板鋼板２ｂを折り曲げたときに内側となる面の所定幅方向の位置に、シカル加工装置のカッターで溝を形成して、所謂シカル加工をする。この位置は、図示の例では、アングル材等の型鋼に決められている２つ折りの片幅（Ｌ＋Ｔ）に対応する寸法精度の範囲内で設定した位置である。 Production of the composite decorative structural members A ₁ is performed in the following procedure. First, as shown in FIG. 3A (a), two thin plates made of stainless steel having a predetermined length (4 to 6 m) whose width direction is cut into a predetermined dimension (width corresponding to the outer peripheral surface of the steel plate). Steel plates 2a and 2b are prepared. It is assumed that the end portions 2e and 2e at both ends of the thin steel plates 2a and 2b are previously cut at 45 degrees. Then, as shown in FIG. 3A (b), a groove is formed by a cutter of a decal processing device at a position in a predetermined width direction on the inner surface when the thin steel plate 2b is bent, and so-called decal processing is performed. To do. In the illustrated example, this position is a position set within a range of dimensional accuracy corresponding to a half-folded half-width (L + T) determined for a shape steel such as an angle member.

上記シカル加工を施した後、プレス曲げ加工機で幅Ｌ、Ｌの位置で薄板鋼板２ｂにプレス圧力を加えて曲げ加工し、図３Ａの（ｃ）図に示すように、２つの幅Ｌ、Ｌ部分を直角に折り曲げ、さらにその先端部分も直角に折り曲げて鉤形の断面状に形成する。その後、折り曲げられた薄板鋼板２ｂの内面の全面、またはこの内面に対応する構造用部材１の外面のいずれか又は両面に接合手段として金属用接着剤５を塗布し、上記断面形状内に構造用部材１を挿入する（図３Ａの（ｄ）図参照）。そして、挿入された構造用部材１に対して薄板鋼板２ｂをプレス機等で強く押し付けて構造用部材１に金属用接着剤５で接合する。なお、１ｆは構造用部材１の内側表面である。   After performing the above-described cical processing, the sheet steel plate 2b is bent by applying a pressing pressure to the sheet steel plate 2b at the position of the width L, L with a press bending machine, and as shown in FIG. The L portion is bent at a right angle, and the tip portion thereof is also bent at a right angle to form a bowl-shaped cross section. Thereafter, the metal adhesive 5 is applied as a joining means to the entire inner surface of the bent thin steel plate 2b or the outer surface of the structural member 1 corresponding to the inner surface, and the structure is within the cross-sectional shape. The member 1 is inserted (see FIG. 3A (d)). Then, the thin steel plate 2b is strongly pressed against the inserted structural member 1 with a press or the like, and is joined to the structural member 1 with the metal adhesive 5. Note that 1 f is an inner surface of the structural member 1.

次に、図３Ｂの（ｅ）図に示すように、もう一枚の薄板鋼板２ａに対してその所定位置に（エッジ部ではなく）曲げ加工を行う。この曲げ加工は、図示のように曲げ加工用丸棒Ｒに対し薄板鋼板２ａの両平面部を押圧して曲げ加工部２ｒを形成する（反対に加工用丸棒Ｒを薄板鋼板２ａの曲げ加工部２ｒの位置で押し付けて加工しても良い）（図３Ｂの（ｆ）図参照）。曲げ加工部２ｒは、一般にアングル材等の型鋼の曲部の内面に沿って密着するように形成される。なお、１ｒは構造用部材１の曲げ加工部である。   Next, as shown in FIG. 3B (e), the other thin steel plate 2a is bent at a predetermined position (not at the edge portion). In this bending process, as shown in the drawing, both flat portions of the thin steel plate 2a are pressed against the bending round bar R to form a bent portion 2r (in contrast, the processing round bar R is bent into the thin steel plate 2a. (It may be processed by pressing at the position of the portion 2r) (see FIG. 3B (f)). The bending portion 2r is generally formed so as to be in close contact with the inner surface of a curved portion of a shape steel such as an angle material. In addition, 1r is a bending part of the structural member 1.

この曲げ加工部２ｒの曲げ加工が終わると、薄板鋼板２ｂの場合と同様に、既に接合されている構造用部材１の屈曲内面の表面又は薄板鋼板２ａの曲げ加工部２ｒの外面に金属用接着剤５を塗布する。そして、薄板鋼板２ａを構造用部材１に対し密着させて接合する。接合が完了すると、図１に示す複合化粧構造用部材Ａ_１が形成される。なお、曲げ加工用丸棒Ｒは、アングル材等の型鋼の内面側の曲り部の円弧曲線に適合する曲げ加工をするのに適する径として、段階的に曲げ加工を進めるために１種類だけでなく、径の異なるものを数本用意しておき、それぞれを曲げ加工の段階に応じて使用するとよい。 When the bending of the bent portion 2r is finished, as in the case of the thin steel plate 2b, the metal bonding is applied to the surface of the bent inner surface of the structural member 1 that has already been joined or the outer surface of the bent portion 2r of the thin steel plate 2a. Agent 5 is applied. Then, the thin steel plate 2a is brought into close contact with the structural member 1 and joined. When the joining is completed, a composite decorative structure member A1 shown in FIG. ₁ is formed. In addition, the round rod R for bending is only one type in order to proceed the bending process step by step as a diameter suitable for bending that conforms to the arc curve of the bent portion on the inner surface side of the shape steel such as an angle material. It is better to prepare several different diameters and use them according to the bending stage.

上記の構成とした複合化粧構造用部材Ａ_１は、上述したように、その用途として構造用部材を目的とし、かつ意匠部材として使用されることを想定したものである。このため、部材の断面が中実断面で、かつ外観は量産されるステンレス型鋼のように表面状態が粗な状態ではなく、設置される場所に必要な荘厳で、高級感、重量感、高品質感のある美感を有する。これは、中心に構造用部材１を配置し、その外周に薄板鋼板２ａ、２ｂを密着して接合、一体化した構成を採用したからである。 As described above, the composite decorative structure member A ₁ having the above-described configuration is intended to be a structural member as a use and is assumed to be used as a design member. For this reason, the cross section of the member is a solid cross section, and the appearance is not a rough state like the mass-produced stainless steel, but it is a majestic necessary for the place where it is installed, high quality, heavy feeling, high quality Has a sense of beauty. This is because the structural member 1 is arranged at the center, and the thin steel plates 2a and 2b are in close contact with each other and joined and integrated.

即ち、外周に配置される薄板鋼板２ａ、２ｂには、接合される前に平板状の段階で、接合、一体化後は外側となる面に対して予め必要な表面仕上げ加工を十分に施すことが出来、屈曲、曲げ加工をする処理を精度よく仕上げることにより従来のステンレス型鋼に要求される表面仕上げ加工を平板状で施すことが出来るため、表面仕上げに掛かる労力を低減でき、かつ表面仕上げ加工の精度が向上し、又強度はステンレス型鋼のような構造用部材と同等又はそれ以上の強度を有し、従って意匠性に優れた美しい外観で、コストの安価な複合化粧構造用部材を提供することが出来る。   That is, the thin steel plates 2a and 2b arranged on the outer periphery are sufficiently subjected to necessary surface finishing in advance on the outer surface after joining and integration in a flat plate stage before joining. By finishing the bending and bending processes with high accuracy, the surface finishing required for conventional stainless steel can be applied in the form of a flat plate, reducing the work required for surface finishing and surface finishing. And the strength is equivalent to or higher than that of a structural member such as stainless steel, and therefore, it provides a beautiful appearance with excellent design and low cost and a low cost composite decorative structural member. I can do it.

ただし、上記表面仕上げ加工とは、上述した例えば鏡面、発色、エッチング、ブラスト、バイブレーション等のいずれかの表面仕上げ、或いはこれらの各種表面仕上げ加工の混合処理である。また、複合化粧構造用部材Ａ_１の構造用部材１とその外周の薄板鋼板２ａ、２ｂを密着、接合する接合手段として金属用接着剤５を使用したが、他の接合手段として例えばねじを用いて構造用部材１と薄板鋼板２ａ、２ｂを止めたり、薄板鋼板２ａ、２ｂに設けた多数の小孔に溶接をして止めたりすることも出来る。その場合、表面仕上げに影響のない範囲の処理を施す必要がある。 However, the above-mentioned surface finishing is the surface finishing of any one of the above-described mirror surfaces, coloring, etching, blasting, vibration, etc., or a mixed processing of these various surface finishings. Further, using the structural member 1 of the composite decorative structural members A ₁ thin steel plate 2a of the outer periphery of the adhesion and 2b, but using a metal adhesive 5 as joining means for joining, for example, screws as another joining means The structural member 1 and the thin steel plates 2a and 2b can be stopped, or the small number of holes provided in the thin steel plates 2a and 2b can be welded and stopped. In that case, it is necessary to perform processing within a range that does not affect the surface finish.
