特許文献１の拘束補助プレートを取り付ける場合は、「拘束補助プレートを、突出部を配管側にしてサポート部材と配管との間に設置する。配管にＵ字形ボルトを被せ、Ｕ字形ボルトのねじ部に調整用ナットを取付け、拘束補助プレートの組付け穴及びサポート部材の組付け穴に通し、固定用ナットを取付ける。すなわち、Ｕ字形ボルトのねじ部に、サポート部材及び拘束補助プレートを挟んでナットを締め付けて固定する（特許文献１、段落００３４参照）」からも明らかなように、Ｕ字型ボルトがサポート部材から取り外されている状態でＵ字型ボルトと拘束補助プレートとを同時に固定する。 When attaching the restraint auxiliary plate of Patent Document 1, "The restraint auxiliary plate is installed between the support member and the pipe with the projecting part on the pipe side. Cover the pipe with a U-shaped bolt, and through the mounting hole of the auxiliary restraint plate and the mounting hole of the support member, and then install the fixing nut.In other words, the support member and restraint auxiliary plate are sandwiched between the threads of the U-shaped bolt and the nut is attached. is fixed by tightening (see Patent Document 1, paragraph 0034)", the U-shaped bolt and the auxiliary restraint plate are fixed at the same time while the U-shaped bolt is removed from the support member.

したがって、既に配管にＵ字形ボルトがかぶせて締結された状態で後から拘束補助プレートを設置する場合には、一旦Ｕ字形ボルトをサポート部材から完全に外し、配管とサポート部材との間に拘束補助プレートを挿入し、その後Ｕ字形ボルトを拘束補助プレートの組付け穴及びサポート部材の組付け穴に通し、固定用ナットを取付ける必要があり、取り付け作業が容易とは言えない。 Therefore, if the restraint assistance plate is to be installed after the piping has already been fastened with U-shaped bolts, the U-shaped bolts must be completely removed from the support member once, and the restraint assistance plate placed between the pipe and the support member will be After inserting the plate, it is necessary to pass the U-shaped bolt through the assembly hole of the auxiliary restraint plate and the assembly hole of the support member, and then install the fixing nut.

本発明は、このような実情に鑑みてなされたもので、その目的は、既にＵ字形ボルトを用いて架台に取り付けられた配管に対して、後からでも容易に取り付けられる配管腐食対策プレート、配管腐食対策部材、及び配管腐食対策構造を提供することにある。 The present invention has been made in view of such circumstances, and its object is to provide a pipe anti-corrosion plate that can be easily attached even later to pipes that have already been attached to a frame using U-shaped bolts. An object of the present invention is to provide a corrosion countermeasure member and a pipe corrosion countermeasure structure.

＜第１実施形態＞
本発明の第１実施形態に係る配管腐食対策構造について、図１乃至図３を参照して説明する。図１は、第１実施形態に係る配管腐食対策構造を示す側面図である。図２は、図１におけるＡ－Ａ矢視図ある。図３は、第１実施形態に係る配管腐食対策部材の説明図である。 <First Embodiment>
A pipe corrosion countermeasure structure according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 3. FIG. FIG. 1 is a side view showing the pipe corrosion countermeasure structure according to the first embodiment. 2 is a view taken along the line AA in FIG. 1. FIG. FIG. 3 is an explanatory diagram of the pipe corrosion countermeasure member according to the first embodiment.

図１に示すように、第１実施形態に係る配管の配管腐食対策構造１は、配管２に近接させて設置した架台３と、配管２に被せて架台３に固定するＵ字形状のＵ字形ボルト４と、架台３と配管２との間に設置した配管腐食対策プレート５と、配管腐食対策プレート５の脱落を抑止する脱落防止プレート６とを含んで構成される。配管腐食対策プレート５及び脱落防止プレート６を総称して配管腐食対策部材という。 As shown in FIG. 1, the pipe corrosion countermeasure structure 1 for pipes according to the first embodiment includes a frame 3 installed in proximity to a pipe 2, and a U-shaped U-shaped structure that covers the pipe 2 and is fixed to the frame 3. It includes a bolt 4, a pipe corrosion countermeasure plate 5 installed between the frame 3 and the pipe 2, and a drop prevention plate 6 for preventing the pipe corrosion countermeasure plate 5 from falling off. The pipe corrosion countermeasure plate 5 and the falling prevention plate 6 are collectively referred to as a pipe corrosion countermeasure member.

架台３は型鋼であり、Ｕ字形ボルト４を取付けるための取付け穴３１（図６参照）が形成されている。架台３は、一端側を図示しない近接の壁（配管２が沿わせられる構造物）に溶接又はボルト等によって固定する。 The pedestal 3 is made of shaped steel, and is provided with mounting holes 31 (see FIG. 6) for mounting the U-shaped bolts 4 thereon. One end of the frame 3 is fixed to a nearby wall (a structure along which the pipe 2 is laid) by welding, bolts, or the like.

Ｕ字形ボルト４は、配管２の外面に沿ってＵ字形状に湾曲するボルト湾曲部４１と、ボルト湾曲部４１の各端部に連続して形成される一対のボルト脚部を備える。一対のボルト脚部は、第１ボルト脚部４２１及び第２ボルト脚部４２２を含む。 The U-shaped bolt 4 includes a bolt curved portion 41 curved in a U shape along the outer surface of the pipe 2 and a pair of bolt legs continuously formed at each end of the bolt curved portion 41 . The pair of bolt legs includes a first bolt leg 421 and a second bolt leg 422 .

第１ボルト脚部４２１及び第２ボルト脚部４２２の各開放端部（ボルト湾曲部４１とは反対側の端部）はねじ溝４２１１、４２２１（図６参照）が形成される。 Thread grooves 4211 and 4221 (see FIG. 6) are formed in the open ends of the first bolt leg portion 421 and the second bolt leg portion 422 (the ends opposite to the bolt curved portion 41).

Ｕ字形ボルト４は、三連ナット７０及び固定用ナット７１によって架台３に固定される。 The U-shaped bolt 4 is fixed to the frame 3 with a triple nut 70 and a fixing nut 71 .

配管腐食対策プレート５は、図３に示すように略矩形状の金属製の板状部材からなる第１基板５１と、第１基板５１の上面に形成された第１突出部５２とを備える。第１突出部５２は配管２の外周面の下部と当接して配管２を支持する。 As shown in FIG. 3 , the pipe corrosion countermeasure plate 5 includes a first substrate 51 made of a substantially rectangular metal plate-like member, and a first projecting portion 52 formed on the upper surface of the first substrate 51 . The first projecting portion 52 supports the pipe 2 by coming into contact with the lower portion of the outer peripheral surface of the pipe 2 .

第１基板５１には、第１ボルト脚部４２１、第２ボルト脚部４２２のそれぞれを挿入するために一方の短辺（第１辺）を切り欠いた第１切欠き部５４１と、一方の長辺（第２辺）を切り欠いた第２切欠き部５４２が形成される。第１切欠き部５４１及び第２切欠き部５４２の切り欠き形状は、第１ボルト脚部４２１、及び第２ボルト脚部４２２の外周径よりも大きく形成される。第１切欠き部５４１の中心部と第２切欠き部５４２の中心部との間の長さは、第１ボルト脚部４２１と第２ボルト脚部４２２との間隔に相当する。 The first board 51 has a first notch portion 541 cut out on one short side (first side) for inserting each of the first bolt leg portion 421 and the second bolt leg portion 422, and a A second notch 542 is formed by notching the long side (second side). The cutout shapes of the first cutout portion 541 and the second cutout portion 542 are formed to be larger than the outer diameters of the first bolt leg portion 421 and the second bolt leg portion 422 . The length between the center portion of the first notch portion 541 and the center portion of the second notch portion 542 corresponds to the distance between the first bolt leg portion 421 and the second bolt leg portion 422 .

第１突出部５２は、配管腐食対策プレート５を配管２と架台３との間に取り付けた状態において、配管２の下部を第１基板５１から浮かせた状態で支持する（図２参照）。本実施形態では、第１突出部５２は、第１基板５１に円柱鋼材を溶接して形成する。 The first projecting portion 52 supports the lower portion of the pipe 2 in a state of being lifted from the first substrate 51 when the pipe corrosion countermeasure plate 5 is attached between the pipe 2 and the mount 3 (see FIG. 2). In this embodiment, the first protrusion 52 is formed by welding a cylindrical steel material to the first substrate 51 .

円柱鋼材は、第１基板５１を配管２と架台３との間に取り付けた状態において、配管２の軸方向と略直交する向きで第１基板５１に溶接される。換言すると、円柱鋼材の軸方向が第１切欠き部５４１及び第２切欠き部５４２の並び方向と円柱鋼材の軸方向が一致する方向で第１基板５１に溶接される。これにより、配管２の軸方向と円柱鋼材の軸方向とを一致させる場合に比べて配管２と円柱鋼材との接触面積を減らすことができる。その結果、配管２を屋外に配置した場合に、配管２と円柱鋼材との間に雨水が滞留しにくくなり、配管２の防錆性を高めつつ、配管２とＵ字形ボルト４との隙間を調整することができる。 The cylindrical steel material is welded to the first substrate 51 in a direction substantially orthogonal to the axial direction of the pipe 2 in a state where the first substrate 51 is attached between the pipe 2 and the mount 3 . In other words, the axial direction of the cylindrical steel material is welded to the first substrate 51 so that the axial direction of the cylindrical steel material coincides with the alignment direction of the first notch 541 and the second notch 542 . As a result, the contact area between the pipe 2 and the cylindrical steel can be reduced as compared with the case where the axial direction of the pipe 2 and the axial direction of the cylindrical steel are aligned. As a result, when the pipe 2 is arranged outdoors, it becomes difficult for rainwater to remain between the pipe 2 and the cylindrical steel material, and the gap between the pipe 2 and the U-shaped bolt 4 is reduced while improving the rust resistance of the pipe 2. can be adjusted.

第１突出部５２は、円柱鋼材を溶接する代わりに、第１基板５１をプレス加工して形成してもよい。 The first projecting portion 52 may be formed by pressing the first substrate 51 instead of welding the cylindrical steel material.

第１基板５１は、第２切欠き部５４２の開口を含む部分領域を、第１突出部５２の突出方向と同じ方向に、かつ、第１突出部５２よりも低く突出させた第２突出部５５が形成される。第２突出部５５の高さは、脱落防止プレート６の第２基板６１の板厚相当である。第２突出部５５と架台３との間に脱落防止プレート６が挿入される。挿入方法は後述する。 The first substrate 51 has a second projection in which a partial region including the opening of the second notch 542 projects in the same direction as the projection direction of the first projection 52 and lower than the first projection 52. 55 is formed. The height of the second projecting portion 55 is equivalent to the thickness of the second substrate 61 of the anti-dropping plate 6 . The drop prevention plate 6 is inserted between the second projecting portion 55 and the pedestal 3 . The insertion method will be described later.

脱落防止プレート６は、第２基板６１に第３切欠き部６４と突出片６６が形成される。 The drop-off prevention plate 6 is formed with a third notch 64 and a projecting piece 66 on the second substrate 61 .

第２基板６１は、一辺が第１基板５１の短辺と同じ長さの略矩形状の金属製の板状部材材により形成される。 The second substrate 61 is formed of a substantially rectangular metal plate member having one side the same length as the short side of the first substrate 51 .

第３切欠き部６４は、第２基板６１における第１基板５１の短辺と同じ長さの辺（第２基板６１における長辺に相当する。）に、第２ボルト脚部４２２を挿入するための切り欠きとして形成される。 The third notch portion 64 inserts the second bolt leg portion 422 into the side of the second substrate 61 that has the same length as the short side of the first substrate 51 (corresponding to the long side of the second substrate 61). It is formed as a cutout for

突出片６６は、第２基板６１の他方の長辺（第４辺）に沿って、第１基板５１の第２突出部５５の高さよりも高く突出した突出片として形成される。 The protruding piece 66 is formed as a protruding piece that protrudes higher than the height of the second protruding portion 55 of the first substrate 51 along the other long side (fourth side) of the second substrate 61 .

Ｕ字形ボルト４で架台３に取り付けられた配管２に、配管腐食対策プレート５を取り付けるには、第１ボルト脚部４２１に第１基板５１の第１切欠き部５４１を差し込み、第１切欠き部５４１を回転中心として配管腐食対策プレート５を配管２の下に回転させながら差し込む。配管腐食対策プレート５は、第２ボルト脚部４２２が第２切欠き部５４２に差し込まれるまで回転する。そして、配管腐食対策プレート５と架台３との間に脱落防止プレート６の第２基板６１を挿入し、第３切欠き部６４が第２ボルト脚部４２２に干渉するまで差し込む。第２基板６１の突出片６６は、第１基板５１の板厚面（側面）と対向させる。 In order to attach the pipe corrosion protection plate 5 to the pipe 2 attached to the frame 3 with the U-shaped bolt 4, the first notch 541 of the first substrate 51 is inserted into the first bolt leg 421, and the first notch With the portion 541 as the center of rotation, the pipe corrosion protection plate 5 is inserted under the pipe 2 while being rotated. The pipe corrosion countermeasure plate 5 rotates until the second bolt leg portion 422 is inserted into the second notch portion 542 . Then, the second substrate 61 of the anti-dropping plate 6 is inserted between the pipe corrosion countermeasure plate 5 and the pedestal 3 until the third notch 64 interferes with the second bolt leg 422 . The projecting piece 66 of the second substrate 61 faces the plate thickness surface (side surface) of the first substrate 51 .

脱落防止プレート６は、第２突出部５５により幅方向への動きが拘束される。 The anti-dropping plate 6 is restrained from moving in the width direction by the second projecting portion 55 .

一方、配管腐食対策プレート５は、配管腐食対策プレート縦方向（配管軸方向）への動きが脱落防止プレート６の突出片６６によって拘束される。 On the other hand, the pipe corrosion countermeasure plate 5 is constrained by the protruding piece 66 of the drop prevention plate 6 against movement in the vertical direction (pipe axial direction) of the pipe corrosion countermeasure plate.

また配管腐食対策プレート５の幅方向への動きは、第２切欠き部５４２と第２ボルト脚部４２２との干渉により拘束される。これにより、配管腐食対策プレート５及び脱落防止プレート６が抜け落ちるのを防ぐ。 Further, the movement of the pipe corrosion countermeasure plate 5 in the width direction is restrained by the interference between the second notch portion 542 and the second bolt leg portion 422 . This prevents the pipe corrosion countermeasure plate 5 and the drop-off prevention plate 6 from coming off.

The cutout shapes of the first cutout portion 541a and the second cutout portion 542a are formed to be larger than the outer diameters of the first bolt leg portion 421 and the second bolt leg portion 422, respectively. The center portion of the first notch portion 541 a and the center portion and length of the second notch portion 542 a correspond to the distance between the first bolt leg portion 421 and the second bolt leg portion 422 .

第１突出部５２ａは、第１基板５１の中央部をプレス加工により突出させて形成される。 The first protruding portion 52a is formed by protruding the central portion of the first substrate 51 by press working.

第１基板５１は、第２切欠き部５４２が形成された部分を立ち上げた第２突出部５５ａが形成される。第２突出部５５ａの高さは、脱落防止プレート６ａの板厚相当である。 The first substrate 51 is formed with a second protruding portion 55a that rises from the portion where the second cutout portion 542 is formed. The height of the second protruding portion 55a is equivalent to the plate thickness of the fall prevention plate 6a.

第１基板５１において、他方の短辺（第３辺）付近は、縦方向の中央から第２辺に向かって、第２突出部５５ａの高さから第１基板５１ａの基準高さ（第２突出部５５ａ以外の上面の高さ）に戻す傾斜面５６と、傾斜面５６の底辺から連続し、第１基板５１ａの基準高さの上面を有するはめ込み部５７を有する。 In the first substrate 51, the vicinity of the other short side (third side) extends from the height of the second projecting portion 55a toward the second side from the center in the vertical direction to the reference height of the first substrate 51a (second and a fitting portion 57 continuous from the bottom of the inclined surface 56 and having an upper surface at the reference height of the first substrate 51a.

脱落防止プレート６ａは、第２基板６１ａに第３切欠き部６４ａと突出片６６ａが形成される。更に、脱落防止プレート６ａにおいて、配管腐食対策プレート５ａと架台３との間に挿入した状態で配管腐食対策プレート５ａのはめ込み部５７に対応する位置には、略矩形状の係止用切欠き部６７が形成される。 The fall prevention plate 6a has a second substrate 61a formed with a third notch 64a and a protruding piece 66a.
