However, it should be understood that the present invention is not limited to such specific fields of use.
背景技術
既知の軽量建築梁の一形状は、増築で用いられるように、2つのロール成形されたC形断面チャネル(溝、溝部、溝状部材)を接合して矩形断面の梁を形成することによって製造される。

この既知の梁に関する短所は、2つのチャネルが互いに対して滑ることがあり、梁のそり、強度の低下、および/またはきしみ音の発生を引き起こしかねないことである。極端な状況下では、この2つのチャネルがねじれ、および/または互いに分離することもあり、その結果、一般に梁欠陥となる。この既知の梁の別の短所は、製造が2つのC形断面チャネルの形成、プレス機における2つのチャネルの位置決め、および次のチャネルを接合するプレス作業を含む、少なくとも2段階の2人での作業となることである。 The disadvantage with this known beam is that the two channels can slide relative to each other, which can cause beam warpage, reduced strength, and / or squeak. Under extreme circumstances, the two channels may twist and / or separate from each other, resulting in beam defects generally. Another disadvantage of this known beam is that at least two stages of manufacture include the formation of two C-section channels, the positioning of the two channels in a press, and the pressing operation to join the next channel. It becomes work.

上記の梁の実施形態は、既知の2部構成の梁に対して多くの利点を有する。まず、それらは若干重いが、この梁は、相当するサイズの2部材梁よりも50〜100%長い距離をわたすことができる。2番目に、この梁は相当するサイズの既知の2部材梁と比較して改善されたねじれ剛性を有する。3番目に、この梁は1人の作業者、単独のロール成形作業によって製造が可能であり、結果として、より低い労働コスト、より低いプラントコスト、および低減されたマニュアルハンドリングがもたらされる。4番目に、この梁は、それ以上の表面加工を必要としないプレコート金属製品を含む各種材料から製造可能である。最後に、この梁は、スチールまたは木材梁の外観を再現し、かつ継ぎ目をカモフラージュする働きを兼ねたくぼみにより審美的に美しい。 The beam embodiment described above has many advantages over known two-part beams. First, they are slightly heavier, but this beam can span a distance 50-100% longer than a correspondingly sized two-member beam. Second, the beam has improved torsional rigidity compared to a known two-member beam of comparable size. Third, the beam can be manufactured by one worker, a single roll forming operation, resulting in lower labor costs, lower plant costs, and reduced manual handling. Fourth, the beam can be manufactured from a variety of materials including pre-coated metal products that do not require further surface processing. Finally, the beam is aesthetically pleasing due to the indentation that reproduces the appearance of a steel or wood beam and also serves as a camouflage for the seam.
本発明は特定の例に関連して説明されてきたが、当業者には本発明を多くの他の形状で実施可能であることが理解されよう。 Although the invention has been described with reference to specific examples, those skilled in the art will recognize that the invention can be implemented in many other forms.
本発明の好ましい実施形態は、一例として、添付の図面に関連してここに説明される。
