Description

本願発明は、板材を配管の長手方向に連接するように巻き付ける外装板の巻き付け構造に関するものである。   The present invention relates to a winding structure of an exterior plate that winds a plate material so as to be connected in the longitudinal direction of a pipe.

図14に図示するように、工場やプラントなどの配管設備では、保温材・断熱材80を取り付けた配管70の外周に板材を巻き付けて外装板90としている。
従来の外装板の巻き付け構造は、図15に図示するように、外装板90の配管長手方向の両端部を鋭角(略レ字形)に折曲してハゼ部91,92を形成し、このハゼ部91,92を相互に係合させるとともに(図15(a))、隣り合う外装板90のハゼ部91,92の一部も重ね合わせるようにして係合させるものである(図15(b)及び(c))。
As shown in FIG. 14, in a piping facility such as a factory or a plant, a plate material is wound around the outer periphery of a pipe 70 to which a heat insulating material / heat insulating material 80 is attached to form an exterior plate 90.
As shown in FIG. 15, the conventional exterior board winding structure is formed by folding both ends of the exterior plate 90 in the longitudinal direction of the pipe into acute angles (substantially letter-shaped) to form the goby portions 91 and 92. The portions 91 and 92 are engaged with each other (FIG. 15 (a)), and part of the goby portions 91 and 92 of the adjacent exterior plates 90 are also overlapped (FIG. 15 (b)). ) And (c)).

この従来の外装板の巻き付け構造に基づいた先行技術文献として、下記に示す特許文献1がある。
この特許文献1は、金属薄板の事前折りや接合手順の工夫により、現場での被覆金属の折曲げ回数を少なくし、かつ良好な接合を可能とすることを目的として、金属薄板を事前に折り曲げ、一側端に内向き折曲部を、他側端に外向き折曲部を形成しておき、外向き折曲部は完全には折り返さず、内向き折曲部の折り返し長さを外向き折曲部の折り返し長さに比べ短くし、被覆金属を鋼管に巻き付けて、内向き折曲部の先端を外向き折曲部の先端に係合しながら、外向き折曲部の折曲位置を支点として係合部をかしめつつ、鋼管の表面側へ押し潰すような形で折り曲げ、はぜ継ぎによる接合部を形成するものである。
As a prior art document based on this conventional exterior board winding structure, there is Patent Document 1 shown below.
This patent document 1 folds a metal thin plate in advance for the purpose of reducing the number of times of folding of the coated metal in the field and enabling good bonding by pre-folding the metal thin plate and devising a joining procedure. An inward bent portion is formed at one end and an outward bent portion is formed at the other end, and the outward bent portion is not completely folded. Shorten the folded length of the facing bent part, wrap the coated metal around the steel pipe, engage the tip of the inward bent part with the tip of the outward bent part, and fold the outward bent part The joint portion is crimped to the surface side of the steel pipe while crimping the engaging portion with the position as a fulcrum, thereby forming a joint portion by a splice.

第2の発明は、切込みが1か所であり、隣り合う外装板のハゼ部と重なり合う内側若しくは隣り合う外装板のハゼ部との境外となる外側に形成したことを特徴とする同外装板の巻き付け構造である。
第3の発明は、切込みが2か所であり、隣り合う外装板のハゼ部と重なり合う内側と隣り合う外装板のハゼ部との境外となる外側に、若しくは、隣り合う外装板のハゼ部と重なり合う内側にのみ形成したことを特徴とする同外装板の巻き付け構造である。
第4の発明は、ハゼ連結部が、三角形状若しくは四角形状に折り返したことを特徴とする同外装板の巻き付け構造である。
第5の発明は、切込みが、隣り合う外装板の一方のハゼ部と重なり合う状態若しくは隣り合う外装板の両方のハゼ部と重なり合う状態で形成したことを特徴とする同外装板の巻き付け構造である。

次に、本願発明の外装板の巻き付け構造(本願発明)と従来の外装板の巻き付け構造(従来技術)との比較試験について説明する。
図11に示す試験片(1)は、従来の外装板の巻き付け構造(従来技術)であり、矩形状の試験片の両端部を鋭角(略レ字形)に折曲してハゼ部を形成し、このハゼ部を重ねて相互に係合させたものである。
図11に示す試験片(2)は、本願発明の外装板の巻き付け構造(本願発明)であり、試験片(1)の係合するハゼ部に切込みを入れてハゼ連結部を備えたものである。
Next, a comparison test between the winding structure of the exterior plate of the present invention (the present invention) and the conventional winding structure of the exterior plate (prior art) will be described.
A test piece (1) shown in FIG. 11 is a conventional exterior board winding structure (conventional technology), in which both ends of a rectangular test piece are bent into acute angles (substantially letter-shaped) to form a goby portion. These goby portions are overlapped and engaged with each other.
The test piece (2) shown in FIG. 11 is a winding structure (invention of the present application) for an exterior plate according to the present invention, and is provided with a gore connecting portion by cutting into the gouge portion with which the test piece (1) is engaged. is there.

図12と図13は、図11に図示した試験片(1)と(2)の強度試験(試験片を引っ張ってハゼ部の状況を検証する試験)の結果を示したものである。ここで、図12は、ハゼ部の最大強度を測定した結果であり、図13は、応力ひずみ曲線をグラフにしたものである。   12 and 13 show the results of the strength test (test for verifying the state of the goby portion by pulling the test piece) of the test pieces (1) and (2) shown in FIG. Here, FIG. 12 is a result of measuring the maximum strength of the goby portion, and FIG. 13 is a graph showing a stress-strain curve.

この試験結果から、以下のことが導き出せた。
(1)従来技術は、ハゼの開き始めが最大応力になる(その時点では外れない)。すなわち、ハゼが開き始める力よりも外れる力が小さいため、開き始めると外れるのは時間の問題となる。
(2)板厚(t)が大きくなるに従い、ハゼ強度は増す。すなわち、0.3tを1とすると、0.35は約1.5倍、0.4は約2倍になる。
(3)本願発明は、ハゼの開き始めに応力の第1ピークがあり、その後ハゼが開ききった段階で最大応力となる(その時点では外れない)。すなわち、ハゼが開いても、外れるためにはさらに強い力が必要になる(従来技術のように、開き始めると外れるのは時間の問題となることはない)。
(4)本願発明のハゼ連結部を設けた箇所は強度が増し、従来技術に対して約5倍の強度となる。
(5)本願発明の第1ピーク値は、従来技術の最大応力よりも大きい(ハゼ連結部によりハゼ部の起き上がり防止効果が期待できる)。
From the test results, the following can be derived.
(1) In the prior art, the start of the goby becomes the maximum stress (it does not come off at that point). In other words, since the force for releasing the goby is smaller than the force for starting to open, it is a matter of time for it to come off when it starts to open.
(2) The goby strength increases as the plate thickness (t) increases. That is, when 0.3t is 1, 0.35 is about 1.5 times and 0.4 is about twice.
(3) In the present invention, there is a first peak of stress at the start of opening of the goby, and the maximum stress is reached at the stage when the goby is fully opened (not removed at that time). In other words, even if the goby opens, a stronger force is required to come off (as in the prior art, when it starts to open, it will not be a problem of time).
(4) The strength of the portion provided with the goby connecting portion of the present invention is increased, and the strength is about five times that of the prior art.
(5) The first peak value of the present invention is larger than the maximum stress of the conventional technology (the effect of preventing the rise of the goby portion can be expected by the gouge connecting portion).
