Description

このように、発明品は従来品の荷重の約２倍で破損するに過ぎなかった。
スタッド曲げ試験
スタッド曲げ試験において、２，７００ｍｍ長の個別のスタッド部が、曲げ荷重で試験された。
一つの従来品および一つの発明品が、試験された。結果は下表に示されている。

試験結果は、スパン／１５０の撓みを生み出す荷重に対して当該部分の性状を示すものとして合理的に理解される。結果の表に示されるように、１５０で除したスパンの撓みにおいて発明品スタッドは従来品スタッドによって支えられる荷重の約１．５倍を支える。両部分に対して経験された破損のモードは使用状態を表すものではないので、当該部分の極限強度に関しては、有効な比較は行うことができない。
プレート曲げ試験
プレート曲げ試験において、８００ｍｍ長の個別のプレート部が曲げ荷重で試験された。撓みにおける曲げ荷重は、プレートが破損に至るまで増分毎に荷重されながら測定された。プレート部はその曲げ軸に関して対称性はないので、試験は上方および下方の両方に面したプレートで行われた。プレート曲げ試験の結果を下に示す。

この試験において、一つの従来品プレートを除いた総ての試験部分は点荷重下で局部的に破損した。従って、局部的破損を除去するために荷重がより広い面積に加えられれば、異なる結果が得られていたであろう。
要約すると、そのフランジアップ発明品プレートは、曲げにおいてフランジアップ従来品プレートの約２．５倍の強度である。
フランジダウン発明品プレートは、フランジダウン従来品プレートよりも曲げにおいて僅かに強い。試験されたような単純な支持プレートとは別の連続したプレートに対しては、発明品は従来品が支える荷重の約１．３倍を支えることができる。
まとめ
試験は、２７００ｍｍ長の発明品スタッドが従来品スタッドの二倍の圧縮荷重に耐えることを示した。
試験は、２７００ｍｍ長の発明品スタッドが、従来品スタッドが耐用限界に至る約１．５倍の曲げ荷重に耐えることも示した。
６００ｍｍスパンの連続したプレートのためのプレート曲げ試験は、発明品プレートが従来品によって支える荷重の１．３倍の荷重を支え、発明品プレートが従来品と略同じ光度を有することを示した。
最後に、試験結果はそれ故、発明品の断面形状が同一材料で概ね同一質量のスチールから作られた従来品の断面形状と同様またはそれ以上に良好であることを示した。
【発明の効果】
上述したフレーム組立体の利点は、このフレーム組立体が、荷重の作用している場合でさえ偏位や変形に抗して連結されるフレーム部材を備えていることである。このことは、スチール建築物の適切な強度の容易かつ効率的な構築を可能にする。ボックス構造や直交座標系のそれぞれに沿った重なり表面等の構造的な特徴は、フレーム強度を向上するとともに、軸方向荷重や捻り荷重に対するフレーム組立体の耐性を向上する。フレーム部材の接合作業は、特別なスキルのない作業者でも、工事の間は非常にシンプルであり、迅速に完了することができ効率的である。
フレーム部材が中空に形成するボックス部に、水道管や電気線、或いは空調機の冷媒管といったユーティリティを挿通することができる。
もちろん、上述したものは、本発明を図示したほんの一例に過ぎず、当業者がなし得るであろう全ての変形やバリエーションは、本件発明の特許請求の範囲内に含まれるものであると認識されるべきである。

Cross section as shown in the drawing(Invention(CDS Section)) Applicant's first and second frame members structural strength,Conventional cross sectionA test compared to a frame member ("C" section) was performed by the Institute of Technology Structure, University of Queensland. Both types are 1.0mmTrade nameManufactured from G550 Zincalume.Conventional productIs formed from a steel sheet approximately 194 mm wide, whileInventionWas formed from a 197 mm wide steel sheet. To simplify the test, there are no restraining devices other than the inevitable restraints that occur at the ends and load points.
The following tests were conducted.
a) Stud compression test
b) Stud bending test
c) Plate bending test
Stud compression test
In the stud compression test, individual studs 2,700 mm long were tested with an axial load. The stud was not constrained to lateral or torsional moments other than by the loading of the plate at each end. The load was applied as evenly as possible.
twoConventional productAnd twoInventionHave been tested. The results are shown in the table below.

in this way,InventionIsConventional productDamaged at about twice the loadI just did.
Stud bending test
In the stud bending test, individual 2,700 mm long studs were tested with a bending load.
OneConventional productAnd oneInventionHave been tested. The results are shown in the table below.

The test results are reasonably understood as showing the properties of the part for loads that produce a span / 150 deflection. As shown in the results table, at the deflection of the span divided by 150InventionStudConventional productSupports about 1.5 times the load supported by the stud. Since the mode of failure experienced for both parts does not represent the state of use, no effective comparison can be made regarding the ultimate strength of the parts.
Plate bending test
In the plate bending test, individual 800 mm long plate portions were tested with a bending load. The bending load at deflection was measured while being loaded in increments until the plate failed. Since the plate part is not symmetric with respect to its bending axis, the test was performed on both the upper and lower facing plates. The results of the plate bending test are shown below.

In this exam, oneConventional productAll test parts except the plate were locally damaged under point load. Thus, different results would have been obtained if a load was applied over a larger area to eliminate local failure.
In summary, its flange upInventionPlates flange up in bendingConventional productIt is about 2.5 times stronger than the plate.
Flange downInventionPlate down flangeConventional productSlightly stronger in bending than plates. For a continuous plate other than a simple support plate as tested,InventionIsConventional productCan support about 1.3 times the load supported by.
Summary
Tests have shown that 2700 mm long invention studs can withstand twice the compressive load of conventional studs.
Tests have also shown that 2700 mm long invention studs can withstand about 1.5 times the bending load that conventional studs reach the service life limit.
Plate bending tests for a 600 mm span continuous plate showed that the inventive plate supported 1.3 times the load supported by the conventional product, and the inventive plate had approximately the same luminous intensity as the conventional product.
Finally, the test results therefore showed that the cross-sectional shape of the invention was as good as or better than that of a conventional product made from steel of the same material and approximately the same mass.
【The invention's effect】
An advantage of the frame assembly described above is that the frame assembly includes a frame member that is coupled against deflection and deformation even when a load is applied. This allows easy and efficient construction of the appropriate strength of the steel building. Structural features, such as overlapping surfaces along each of the box structure and Cartesian coordinate system, improve the frame strength and improve the frame assembly's resistance to axial and torsional loads. The work of joining the frame members is very simple even during the construction, even for workers without special skills, and can be completed quickly and is efficient.
A utility such as a water pipe, an electric wire, or a refrigerant pipe of an air conditioner can be inserted into the box portion formed hollow by the frame member.
Of course, what has been described above is merely illustrative of the invention, and all modifications and variations that could be made by those skilled in the art are intended to be included within the scope of the claims of the present invention. Should be.
