The shaft portion 43 is a portion of the rod-shaped member 42 from the second end portion 42c to the first straight line portion 44a.

第２直線部４４ｃが第１直線部４４ａに交差するように弧状部４４ｂを折り曲げる向きは、雄ねじ４３ａの螺進方向（矢印Ｙ）と同じである。ワイヤ保持部材４１を、ワイヤ保持部４４側から見た平面視では、弧状部４４ｂは、第１直線部４４ａから時計回り（右回り）となるように折り曲げられている。 The direction in which the arcuate portion 44b is bent so that the second straight line portion 44c intersects the first straight line portion 44a is the same as the screwing direction (arrow Y) of the male screw 43a. When the wire holding member 41 is viewed from the wire holding portion 44 side in a plan view, the arc-shaped portion 44b is bent so as to be clockwise (clockwise) from the first straight line portion 44a.

図４に示すように、先端棒状部４２ａが環状に見えるように、軸部４３の径方向に沿ってワイヤ保持部４４を見た場合、そのワイヤ保持部４４と第１直線部４４ａとで囲まれた部位の内側には空間部４６が形成される。先端棒状部４２ａが環状に見えるように、軸部４３の径方向に沿ってワイヤ保持部４４を見た場合において、空間部４６の内縁を繋いで形成される仮想円Ｃの直径は、ワイヤ２１の直径より長い。また、図５（ｂ）に示すように、ワイヤ保持部材４１を、軸部４３の径方向に沿って第１端部４２ｂ側から見た場合、第１直線部４４ａとワイヤ保持部４４（第２直線部４４ｃ）とは離間しており、その離間した部分に布設具２０のワイヤ２１を挿入できる隙間が形成されている。 As shown in FIG. 4, when the wire holding portion 44 is viewed along the radial direction of the shaft portion 43 so that the tip rod-shaped portion 42a looks like an annular shape, it is surrounded by the wire holding portion 44 and the first straight line portion 44a. A space 46 is formed inside the removed portion. When the wire holding portion 44 is viewed along the radial direction of the shaft portion 43 so that the tip rod-shaped portion 42a looks like an annular shape, the diameter of the virtual circle C formed by connecting the inner edges of the space portions 46 is the wire 21.

It is separated from the two straight portions 44c), and a gap is formed in the separated portion into which the wire 21 of the laying tool 20 can be inserted.

図２又は図３に示すように、サポート部材５１は、金属製の長板５０を整形して形成された第１部材５２と、金属製の矩形板を整形して形成された第２部品６２と、から構成されている。第１部材５２は、長板５０の長手方向一端側に設けられた板状のサポート部材用固定部５３と、サポート部材用固定部５３から延設された長尺状の延設部５４と、延設部５４に一体化され、長板５０の長手方向他端側に設けられた板状の組付部５５と、を備える。 As shown in FIG. 2 or 3, the support member 51 includes a first member 52 formed by shaping a long metal plate 50 and a second component 62 formed by shaping a rectangular metal plate.

サポート部材用固定部５３は、平板状である。サポート部材用固定部５３は、壁Ｗに接する面に内面５３ａを備え、内面５３ａに平行な面に外面５３ｂを備える。第１部材５２は、サポート部材用固定部５３に長孔状の貫通孔５３ｃを備える。 The support member fixing portion 53 has a flat plate shape. The support member fixing portion 53 includes an inner surface 53a on a surface in contact with the wall W, and an outer surface 53b on a surface parallel to the inner surface 53a. The first member 52 includes an elongated through hole 53c in the support member fixing portion 53.

延設部５４は、短手方向の中央部が長手方向のほぼ全体に亘って折り曲げられ、この折り曲げにより長手方向への剛性が高められている。延設部５４は、谷折りとなる面に内面５４ａを備え、山折りとなる面に外面５４ｂを備える。延設部５４の外面５４ｂは、サポート部材用固定部５３の外面５３ｂに斜めに交差し、延設部５４の内面５４ａは、サポート部材用固定部５３の内面５３ａに斜めに交差している。よって、延設部５４は、サポート部材用固定部５３に対し斜めに交差している。 The extension portion 54 is bent at the central portion in the lateral direction over substantially the entire longitudinal direction, and the rigidity in the longitudinal direction is increased by this bending. The extension portion 54 is provided with an inner surface 54a on a surface that becomes a valley fold and an outer surface 54b on a surface that becomes a mountain fold. The outer surface 54b of the extension portion 54 diagonally intersects the outer surface 53b of the support member fixing portion 53, and the inner surface 54a of the extension portion 54 diagonally intersects the inner surface 53a of the support member fixing portion 53. Therefore, the extension portion 54 intersects the support member fixing portion 53 at an angle.

組付部５５は平板状である。第１部材５２は、ワイヤ保持部材４１の軸部４３を貫通させる貫通部５５ａを組付部５５に備える。貫通部５５ａは、延設部５４の長手方向に沿って延びる組付部５５の一対の側縁のうちの一方から凹む形状である。第１部材５２は、組付部５５に複数の係止凸部５５ｂを備える。複数の係止凸部５５ｂは、延設部５４の長手方向に沿って貫通部５５ａを挟む位置それぞれに２つずつ設けられている。各係止凸部５５ｂは、組付部５５の下面から凹み、組付部５５の上面から突出する形状であり、組付部５５から第２部品６２に向けて突出する円柱状である。 The assembly portion 55 has a flat plate shape. The first member 52 is provided with a penetrating portion 55a for penetrating the shaft portion 43 of the wire holding member 41 in the assembling portion 55. The penetrating portion 55a has a shape that is recessed from one of a pair of side edges of the assembling portion 55 that extends along the longitudinal direction of the extending portion 54. The first member 52 includes a plurality of locking convex portions 55b in the assembling portion 55. Two locking convex portions 55b are provided at each position of sandwiching the penetrating portion 55a along the longitudinal direction of the extending portion 54. Each locking convex portion 55b has a shape that is recessed from the lower surface of the assembling portion 55 and protrudes from the upper surface of the assembling portion 55, and is a columnar shape that protrudes from the assembling portion 55 toward the second component 62.

第２部品６２は、矩形板をＶ字状に整形して形成されている。第２部品６２は、組付部５５に支持され、軸部４３の外面に接触する当接部として機能する支持片６３と、支持片６３に連設され、かつ支持片６３に対し斜めに交差し、軸部４３に接触して当接部として機能する当接片６４とを備える。第２部品６２は、支持片６３に第１挿通孔６３ａ（図３又は図４参照）を備える。第１挿通孔６３ａは、支持片６３の中央に円孔状に形成されている。また、第２部品６２は、支持片６３に係止凹部６３ｂを複数備える。複数の係止凹部６３ｂは、第１挿通孔６３ａを取り囲むように設けられている。組付部５５に第２部品６２を支持させた状態では、各係止凹部６３ｂに係止凸部５５ｂが入り込む。 The second component 62 is formed by shaping a rectangular plate into a V shape. The second component 62 is connected to the support piece 63, which is supported by the assembly portion 55 and functions as a contact portion that contacts the outer surface of the shaft portion 43, and is connected to the support piece 63 and intersects the support piece 63 at an angle. A contact piece 64 that comes into contact with the shaft portion 43 and functions as a contact portion is provided. The second component 62 includes a first insertion hole 63a (see FIG. 3 or 4) in the support piece 63. The first insertion hole 63a is formed in a circular hole shape in the center of the support piece 63. Further, the second component 62 includes a plurality of locking recesses 63b in the support piece 63. The plurality of locking recesses 63b are provided so as to surround the first insertion hole 63a. In a state where the second component 62 is supported by the assembly portion 55, the locking convex portion 55b enters each locking recess 63b.

第２部品６２は、当接片６４に第２挿通孔６４ａを備える。第２挿通孔６４ａは、６３と当接片６４を繋ぐ方向、すなわち、第２部品６２の材料となる矩形板の長手方向に長手が延びる長孔状である。ワイヤ保持部４４側からワイヤ保持装置４０を見た平面視では、第２挿通孔６４ａと第１挿通孔６３ａとは重なり合う位置にある。 The second component 62 includes a second insertion hole 64a in the contact piece 64. The second insertion hole 64a has an elongated hole shape that extends in the direction connecting the 63 and the contact piece 64, that is, in the longitudinal direction of the rectangular plate that is the material of the second component 62. When the wire holding device 40 is viewed from the wire holding portion 44 side in a plan view, the second insertion hole 64a and the first insertion hole 63a are located at overlapping positions.

次に、ワイヤ保持装置４０の設置方法を説明する。なお、ワイヤ保持装置４０を設置する場所には、既に布設具２０が布設されている。この段階では、ワイヤ２１には長手方向に若干の張力が付与されている。なお、ワイヤ保持装置４０の設置後にもワイヤ２１に張力が付与されて布設具２０の布設が完了するため、この段階でワイヤ２１に付与される張力は、布設具２０の布設完了時に付与されている張力より弱い。 Next, a method of installing the wire holding device 40 will be described. The laying tool 20 has already been laid at the place where the wire holding device 40 is installed. At this stage, some tension is applied to the wire 21 in the longitudinal direction. Since tension is applied to the wire 21 and the laying of the laying tool 20 is completed even after the wire holding device 40 is installed, the tension applied to the wire 21 at this stage is applied when the laying of the laying tool 20 is completed. Weaker than the tension.

まず、ワイヤ保持部材４１の軸部４３を、第２端部４２ｃ側から第２部品６２の第２挿通孔６４ａに挿通した後、当接片６４を貫通した軸部４３の雄ねじ４３ａに一対の組付ナット６７のうちの一方を螺着する。次に、軸部４３を第２部品６２の第１挿通孔６３ａに挿通した後、支持片６３を貫通した軸部４３の雄ねじ４３ａに他方の組付ナット６７を螺着する。そして、一対の組付ナット６７をワイヤ保持部４４に向けて螺進させつつ、第２部品６２をワイヤ保持部４４側へ移動させる。当接片６４の内周縁が軸部４３における第１直線部４４ａに当接し、支持片６３の内周縁が軸部４３の中途部に当接する位置に第２部品６２を配置する。また、軸部４３に固定用ナット４８及びワッシャ４９を装着する。 First, the shaft portion 43 of the wire holding member 41 is inserted into the second insertion hole 64a of the second component 62 from the second end portion 42c side, and then a pair of male threads 43a of the shaft portion 43 penetrating the contact piece 64. One of the assembly nuts 67 is screwed. Next, after inserting the shaft portion 43 into the first insertion hole 63a of the second component 62, the other assembling nut 67 is screwed onto the male screw 43a of the shaft portion 43 penetrating the support piece 63. Then, the second component 62 is moved toward the wire holding portion 44 while the pair of assembling nuts 67 are screwed toward the wire holding portion 44. The second component 62 is arranged at a position where the inner peripheral edge of the contact piece 64 abuts on the first straight line portion 44a of the shaft portion 43 and the inner peripheral edge of the support piece 63 abuts on the middle portion of the shaft portion 43. Further, the fixing nut 48 and the washer 49 are attached to the shaft portion 43.

次に、図６に示すように、壁Ｗにおいて、ワイヤ保持部材４１を立設する場所に埋設されたアンカー部材６０に、ワイヤ保持部材４１の固定部４５（雄ねじ４３ａ）を螺合する。なお、アンカー部材６０は、樹脂製のホルダ６１の内側にナット６１ａが保持された構造であり、ナット６１ａの雌ねじ６１ｂにワイヤ保持部材４１の固定部４５が螺合される。 Next, as shown in FIG. 6, the fixing portion 45 (male screw 43a) of the wire holding member 41 is screwed into the anchor member 60 embedded in the place where the wire holding member 41 is erected on the wall W. The anchor member 60 has a structure in which the nut 61a is held inside the resin holder 61, and the fixing portion 45 of the wire holding member 41 is screwed into the female screw 61b of the nut 61a.

そして、固定部４５の螺合量を調整し、ワイヤ保持部４４を布設具２０のワイヤ２１付近に位置させた後、布設具２０のワイヤ２１を、ワイヤ保持部材４１の第１直線部４４ａと第２直線部４４ｃとの間の隙間に入り込ませる。その後、ワイヤ保持部材４１を一周回転させてナット６１ａに螺進させると、ワイヤ保持部材４１の螺進に伴い、ワイヤ２１が弧状部４４ｂに巻き込まれ、空間部４６にワイヤ２１が入り込む状態となる。その結果、ワイヤ保持部４４にワイヤ中途部２１ａが遊挿される。なお、ワイヤ中途部２１ａがワイヤ保持部４４に遊挿されるように、ナット６１ａに対するワイヤ保持部材４１の螺合量が調節される。「遊挿」とは、ワイヤ中途部２１ａが空間部４６内での径方向への若干の移動が許容された状態で挿通されていることを言う。そして、空間部４６にワイヤ中途部２１ａが遊挿されているため、後に、布設具２０の布設完了のためにワイヤ２１に張力を付与した際にワイヤ２１の長手方向への移動が許容される。 Then, after adjusting the screwing amount of the fixing portion 45 and positioning the wire holding portion 44 near the wire 21 of the laying tool 20, the wire 21 of the laying tool 20 is aligned with the first straight portion 44a of the wire holding member 41. It is inserted into the gap between the second straight portion 44c and the second straight portion 44c. After that, when the wire holding member 41 is rotated once and screwed into the nut 61a, the wire 21 is caught in the arcuate portion 44b as the wire holding member 41 is screwed, and the wire 21 enters the space portion 46. .. As a result, the wire midway portion 21a is loosely inserted into the wire holding portion 44. The amount of screwing of the wire holding member 41 with respect to the nut 61a is adjusted so that the wire intermediate portion 21a is loosely inserted into the wire holding portion 44. The “free insertion” means that the wire midway portion 21a is inserted in a state where a slight radial movement in the space portion 46 is allowed. Since the wire midway portion 21a is loosely inserted into the space portion 46, the wire 21 is allowed to move in the longitudinal direction when tension is applied to the wire 21 to complete the laying of the laying tool 20 later. ..

そして、雄ねじ４３ａに螺着された固定用ナット４８をワッシャ４９に向けて螺進させ、固定用ナット４８によってワイヤ保持部材４１を回り止めする。すると、ワイヤ保持部材４１は、壁Ｗに対し直交する方向に軸部４３の長手方向が延び、軸部４３の長手方向がワイヤ保持部材４１の立設方向に一致する状態に立設される。その結果、ワイヤ保持部材４１は、立設方向の一端側の固定部４５（雄ねじ４３ａ）によって壁Ｗに固定される。ワイヤ保持部材４１は、壁Ｗから立設された状態では、立設方向の他端側にワイヤ保持部４４を備えることとなる。また、一対のワイヤ保持部材４１の各突出部４７は、当該突出部４７を有するワイヤ保持部４４に遊挿されている一方のワイヤ２１とは異なる他方のワイヤ２１とは反対側に向けて第１直線部４４ａから突出している。 Then, the fixing nut 48 screwed to the male screw 43a is screwed toward the washer 49, and the wire holding member 41 is stopped by the fixing nut 48. Then, the wire holding member 41 is erected in a state in which the longitudinal direction of the shaft portion 43 extends in the direction orthogonal to the wall W and the longitudinal direction of the shaft portion 43 coincides with the erection direction of the wire holding member 41. As a result, the wire holding member 41 is fixed to the wall W by the fixing portion 45 (male screw 43a) on one end side in the vertical direction. When the wire holding member 41 is erected from the wall W, the wire holding member 41 is provided with the wire holding portion 44 on the other end side in the erection direction. Further, each of the protruding portions 47 of the pair of wire holding members 41 is directed toward the side opposite to the other wire 21 which is different from the one wire 21 loosely inserted into the wire holding portion 44 having the protruding portion 47. 1 It protrudes from the straight portion 44a.

次に、第１部材５２のサポート部材用固定部５３の貫通孔５３ｃに、固定ボルト７０を貫通させるとともに、その固定ボルト７０を壁Ｗに埋設されたアンカー部材６０に螺合する。すると、サポート部材用固定部５３が壁Ｗに固定される。 Next, the fixing bolt 70 is passed through the through hole 53c of the support member fixing portion 53 of the first member 52, and the fixing bolt 70 is screwed into the anchor member 60 embedded in the wall W. Then, the support member fixing portion 53 is fixed to the wall W.

次に、ワイヤ保持部材４１の軸部４３において、第２部品６２の支持片６３と、他方の組付ナット６７との間に、第１部材５２の組付部５５を差し込み、組付部５５の貫通部５５ａに軸部４３を貫通させる。また、組付部５５の係止凸部５５ｂを、支持片６３の係止凹部６３ｂに入り込ませる。そして、一対の組付ナット６７により、組付部５５及び支持片６３を挟持する。この挟持により、第１部材５２がワイヤ保持部材４１に回り止めされた状態で組付けられるとともに、第２部品６２がワイヤ保持部材４１に回り止めされた状態で組付けられる。その後、布設具２０のワイヤ２１それぞれに張力が付与され、布設具２０の布設が完了するとともに、ワイヤ中途部２１ａの保持構造が完成する。 Next, in the shaft portion 43 of the wire holding member 41, the assembling portion 55 of the first member 52 is inserted between the support piece 63 of the second component 62 and the other assembling nut 67, and the assembling portion 55 is inserted. The shaft portion 43 is passed through the penetrating portion 55a of the above. Further, the locking convex portion 55b of the assembling portion 55 is inserted into the locking concave portion 63b of the support piece 63. Then, the assembling portion 55 and the support piece 63 are sandwiched by the pair of assembling nuts 67. By this sandwiching, the first member 52 is assembled in a state of being stopped by the wire holding member 41, and the second component 62 is assembled in a state of being stopped by the wire holding member 41. After that, tension is applied to each of the wires 21 of the laying tool 20, the laying of the laying tool 20 is completed, and the holding structure of the wire midway portion 21a is completed.

その結果、第１部材５２の長手方向一端側がサポート部材用固定部５３によって壁Ｗに固定されるとともに、第１部材５２の長手方向他端側が組付部５５及び組付ナット６７によってワイヤ保持部材４１に固定される。第１部材５２は、ワイヤ保持部材４１と壁Ｗに架設された状態となる。よって、サポート部材５１は、その延設部５４がワイヤ保持部材４１の立設方向に対し傾斜した状態で、ワイヤ保持部材４１に組付けられている。そして、サポート部材５１の第１部材５２により、ワイヤ保持部材４１が斜めに支えられている。 As a result, one end side of the first member 52 in the longitudinal direction is fixed to the wall W by the support member fixing portion 53, and the other end side of the first member 52 in the longitudinal direction is fixed to the wall W by the assembling portion 55 and the assembling nut 67. It is fixed at 41. The first member 52 is erected on the wire holding member 41 and the wall W. Therefore, the support member 51 is assembled to the wire holding member 41 in a state where the extending portion 54 is inclined with respect to the erection direction of the wire holding member 41. The wire holding member 41 is diagonally supported by the first member 52 of the support member 51.

図７に示すように、壁Ｗを正面から見た正面視において、第１部材５２の長手は水平方向（左右方向）に延びている。詳細には、各第１部材５２は、その長手が水平方向に沿ってワイヤ２１の外側に向けて延びている。よって、第１部材５２の長手方向は、布設具２０のワイヤ２１の長手方向と直交し、ワイヤ２１の長手方向と異なる方向に延びている。また、図６に示すように、平面視において、第１部材５２の長手は、奥行方向（前後方向）にも延びており、ワイヤ２１の長手方向と異なる方向に延びている。 As shown in FIG. 7, when the wall W is viewed from the front, the length of the first member 52 extends in the horizontal direction (horizontal direction). Specifically, each first member 52 extends laterally in its longitudinal direction toward the outside of the wire 21. Therefore, the longitudinal direction of the first member 52 is orthogonal to the longitudinal direction of the wire 21 of the laying tool 20, and extends in a direction different from the longitudinal direction of the wire 21. Further, as shown in FIG. 6, in a plan view, the length of the first member 52 also extends in the depth direction (front-back direction), and extends in a direction different from the length direction of the wire 21.

また、第２部品６２において、支持片６３における第１挿通孔６３ａの内周縁が軸部４３に接触し、当接片６４における第２挿通孔６４ａの内周縁が軸部４３のうちの第１直線部４４ａに接触している。よって、第２部品６２は、組付部５５に対し、ワイヤ保持部材４１の立設方向に沿ってワイヤ保持部４４側にずれた２箇所で接触している。そして、ワイヤ保持部材４１の軸部４３に対し２箇所で接触する第２部品６２は、一対の組付ナット６７によってワイヤ保持部材４１に固定されている。 Further, in the second component 62, the inner peripheral edge of the first insertion hole 63a in the support piece 63 contacts the shaft portion 43, and the inner peripheral edge of the second insertion hole 64a in the contact piece 64 is the first of the shaft portions 43. It is in contact with the straight line portion 44a. Therefore, the second component 62 is in contact with the assembly portion 55 at two locations shifted toward the wire holding portion 44 along the vertical direction of the wire holding member 41. The second component 62, which comes into contact with the shaft portion 43 of the wire holding member 41 at two points, is fixed to the wire holding member 41 by a pair of assembling nuts 67.

図６又は図７に示すように、建物の壁Ｗには、上記のように設置されたワイヤ保持装置４０が、布設具２０の各ワイヤ２１に対応して１つずつ設置されている。なお、一対のワイヤ保持部材４１は、一対のワイヤ保持部４４の間隔が、布設具２０の一対のワイヤ２１の間隔に合致するように壁Ｗに立設されている。 As shown in FIG. 6 or 7, on the wall W of the building, one wire holding device 40 installed as described above is installed corresponding to each wire 21 of the laying tool 20. The pair of wire holding members 41 are erected on the wall W so that the distance between the pair of wire holding portions 44 matches the distance between the pair of wires 21 of the laying tool 20.

ワイヤ中途部２１ａの保持構造の各ワイヤ保持装置４０において、ワイヤ保持部４４の空間部４６にはワイヤ中途部２１ａが遊挿されている。一対のワイヤ保持装置４０は、一方のワイヤ保持装置４０におけるワイヤ保持部材４１の突出部４７が、他方のワイヤ保持装置４０とは反対側に向けて突出するように壁Ｗに固定されている。すなわち、各突出部４７は、当該突出部４７が有するワイヤ保持部４４に遊挿されている一方のワイヤ２１とは異なる他方のワイヤ２１と反対側に向けて突出している。したがって、一対の突出部４７は、相反する方向に向けてワイヤ保持部４４から突出している。 In each wire holding device 40 having a holding structure of the wire middle portion 21a, the wire middle portion 21a is loosely inserted into the space portion 46 of the wire holding portion 44. The pair of wire holding devices 40 are fixed to the wall W so that the protruding portion 47 of the wire holding member 41 in one wire holding device 40 projects toward the opposite side to the other wire holding device 40. That is, each protruding portion 47 projects toward the side opposite to the other wire 21 which is different from the one wire 21 loosely inserted in the wire holding portion 44 of the protruding portion 47. Therefore, the pair of projecting portions 47 project from the wire holding portion 44 in opposite directions.

次に、ワイヤ保持装置４０及びワイヤ中途部２１ａの保持構造の作用を記載する。
さて、布設具２０の布設が完了し、ワイヤ中途部２１ａがワイヤ保持部４４に遊挿された状態において、地震等によってワイヤ２１が振れた場合、各ワイヤ２１は、ワイヤ保持部４４の内周縁に接触する。すると、ワイヤ２１の振れによって発生する外力がワイヤ保持部材４１に作用する。 Next, the operation of the holding structure of the wire holding device 40 and the wire intermediate portion 21a will be described.
When the laying of the laying tool 20 is completed and the wire 21 is loosely inserted into the wire holding portion 44 and the wire 21 swings due to an earthquake or the like, each wire 21 has an inner peripheral edge of the wire holding portion 44. Contact. Then, an external force generated by the runout of the wire 21 acts on the wire holding member 41.

ワイヤ保持部材４１において、ワイヤ保持部４４と組付部５５との間の部位には第２部品６２が２箇所接触しており、第２部品６２は、一対の組付ナット６７によって回り止めされた状態でワイヤ保持部材４１に固定されている。このため、第２部品６２により、ワイヤ保持部材４１におけるワイヤ保持部４４と組付部５５との間の部位が補強され、当該部位がワイヤ２１の振れによって変形することが抑制される。 In the wire holding member 41, the second part 62 is in contact with the portion between the wire holding portion 44 and the assembling portion 55 at two points, and the second part 62 is stopped by a pair of assembling nuts 67. It is fixed to the wire holding member 41 in the state of being fixed. Therefore, the second component 62 reinforces the portion of the wire holding member 41 between the wire holding portion 44 and the assembling portion 55, and prevents the portion from being deformed by the runout of the wire 21.

また、ワイヤ保持部材４１は、サポート部材５１の第１部材５２により、補強されており、ワイヤ２１の振れによってワイヤ保持部材４１に作用した外力は第１部材５２によって支承される。具体的には、ワイヤ保持部材４１の軸部４３から第１部材５２の組付部５５に伝わった外力は、延設部５４及びサポート部材用固定部５３を介して壁Ｗに支承される。その結果、外力によってワイヤ保持部材４１が変形することが抑制される。 Further, the wire holding member 41 is reinforced by the first member 52 of the support member 51, and the external force acting on the wire holding member 41 due to the runout of the wire 21 is supported by the first member 52. Specifically, the external force transmitted from the shaft portion 43 of the wire holding member 41 to the assembling portion 55 of the first member 52 is supported by the wall W via the extending portion 54 and the fixing portion 53 for the support member. As a result, deformation of the wire holding member 41 due to an external force is suppressed.

第１部材５２の組付部５５にも、外力が作用するが、組付部５５の係止凸部５５ｂが支持片６３の係止凹部６３ｂに係止することで、組付部５５において、貫通部５５ａが開く方向への変形が抑制される。 An external force also acts on the assembling portion 55 of the first member 52, but the locking convex portion 55b of the assembling portion 55 is locked to the locking recess 63b of the support piece 63, so that the assembling portion 55 Deformation in the opening direction of the penetrating portion 55a is suppressed.

その結果、布設具２０の各ワイヤ２１において、ワイヤ中途部２１ａの振れがワイヤ保持装置４０によって抑制され、布設具２０に沿って布設された配線・配管材Ｐの振れも抑制される。 As a result, in each wire 21 of the laying tool 20, the runout of the wire midway portion 21a is suppressed by the wire holding device 40, and the runout of the wiring / piping material P laid along the laying tool 20 is also suppressed.

上記実施形態によれば、以下のような効果を得ることができる。
（１）ワイヤ保持装置４０のワイヤ保持部材４１は、アンカー部材６０に対する固定部４５の螺合量を調節することにより、壁Ｗからのワイヤ保持部４４の位置を調整できる。さらに、ワイヤ保持部材４１は、棒状部材４２からなるため、剛性を高めた大型の溝形鋼を用いる必要がなく、ワイヤ保持装置４０の軽量化に繋がる。そして、ワイヤ保持部４４の位置を調整可能としたワイヤ保持部材４１には、第１部材５２の組付部５５が組付けられるとともに、第１部材５２のサポート部材用固定部５３が壁Ｗに固定されている。そして、この第１部材５２の延設部５４によってワイヤ保持部材４１は斜めに支持されている。このため、ワイヤ保持部４４にワイヤ２１が遊挿されていることから、地震等によってワイヤ２１がワイヤ保持部４４内で振れ、ワイヤ保持部材４１に外力が作用しても、サポート部材５１によって外力を支承し、ワイヤ保持部材４１の変形を抑制できる。 According to the above embodiment, the following effects can be obtained.
(1) The wire holding member 41 of the wire holding device 40 can adjust the position of the wire holding portion 44 from the wall W by adjusting the screwing amount of the fixing portion 45 with respect to the anchor member 60. Further, since the wire holding member 41 is made of a rod-shaped member 42, it is not necessary to use a large channel steel having increased rigidity, which leads to a weight reduction of the wire holding device 40. Then, the assembly portion 55 of the first member 52 is assembled to the wire holding member 41 whose position of the wire holding portion 44 can be adjusted, and the support member fixing portion 53 of the first member 52 is attached to the wall W. It is fixed. The wire holding member 41 is diagonally supported by the extending portion 54 of the first member 52. Therefore, since the wire 21 is loosely inserted into the wire holding portion 44, even if the wire 21 swings in the wire holding portion 44 due to an earthquake or the like and an external force acts on the wire holding member 41, the support member 51 causes an external force. It is possible to suppress the deformation of the wire holding member 41.

（２）ワイヤ保持部材４１の固定部４５は、軸部４３に設けた雄ねじ４３ａである。このため、アンカー部材６０に対する雄ねじ４３ａの螺合量を調節するだけの簡単な作業で、ワイヤ保持部４４の壁Ｗからの離間距離を調整できる。 (2) The fixing portion 45 of the wire holding member 41 is a male screw 43a provided on the shaft portion 43. Therefore, the separation distance of the wire holding portion 44 from the wall W can be adjusted by a simple operation of adjusting the screwing amount of the male screw 43a with respect to the anchor member 60.

（３）サポート部材５１の第１部材５２において、組付部５５は平板状である。また、ワイヤ保持部材４１の軸部４３には一対の組付ナット６７が螺着され、この一対の組付ナット６７によって組付部５５が挟持されることにより、第１部材５２がワイヤ保持部材４１に組付けられている。一対の組付ナット６７の螺着位置は簡単に調整できるため、この一対の組付ナット６７に挟持される組付部５５及び第２部品６２の位置も簡単に調整できる。 (3) In the first member 52 of the support member 51, the assembly portion 55 has a flat plate shape. Further, a pair of assembling nuts 67 are screwed to the shaft portion 43 of the wire holding member 41, and the assembling portion 55 is sandwiched by the pair of assembling nuts 67, so that the first member 52 is a wire holding member. It is assembled to 41. Since the screwing positions of the pair of assembling nuts 67 can be easily adjusted, the positions of the assembling portion 55 and the second component 62 sandwiched between the pair of assembling nuts 67 can also be easily adjusted.

（４）固定部４５として機能させる雄ねじ４３ａに螺着した組付ナット６７により、第１部材５２の組付部５５をワイヤ保持部材４１に固定できる。よって、固定部４５として機能させる雄ねじ４３ａを、第１部材５２をワイヤ保持部材４１に組付けるための構成として使用でき、ワイヤ保持部材４１を壁Ｗに固定するための構成（固定部４５）と、第１部材５２をワイヤ保持部材４１に組付けるための構成（組付ナット６７）とを別々に設ける場合と比べて、ワイヤ保持装置４０の構成を簡素化できる。 (4) The assembling portion 55 of the first member 52 can be fixed to the wire holding member 41 by the assembling nut 67 screwed to the male screw 43a that functions as the fixing portion 45. Therefore, the male screw 43a that functions as the fixing portion 45 can be used as a configuration for assembling the first member 52 to the wire holding member 41, and the configuration for fixing the wire holding member 41 to the wall W (fixing portion 45). The configuration of the wire holding device 40 can be simplified as compared with the case where the first member 52 is separately provided with the configuration for assembling the first member 52 to the wire holding member 41 (assembling nut 67).

（５）サポート部材５１の第１部材５２は、一対の組付ナット６７によって組付部５５を挟持することでワイヤ保持部材４１に組付けられている。よって、第１部材５２をワイヤ保持部材４１に着脱可能とすることができ、第１部材５２の交換等も容易となる。 (5) The first member 52 of the support member 51 is assembled to the wire holding member 41 by sandwiching the assembling portion 55 with a pair of assembling nuts 67. Therefore, the first member 52 can be attached to and detached from the wire holding member 41, and the first member 52 can be easily replaced.

（６）サポート部材５１の第２部品６２は、ワイヤ保持部材４１に対し２箇所で接触している。このため、第２部品６２により、ワイヤ保持部材４１における組付部５５よりもワイヤ保持部４４側を補強できる。 (6) The second component 62 of the support member 51 is in contact with the wire holding member 41 at two points. Therefore, the second component 62 can reinforce the wire holding portion 44 side of the wire holding member 41 with respect to the assembled portion 55.

（７）ワイヤ保持部材４１を補強する第１部材５２は、組付ナット６７によってワイヤ保持部材４１に組付けられている。そして、組付ナット６７よりもワイヤ保持部４４側に第２部品６２を設け、ワイヤ保持部材４１のうち、第１部材５２で補強しにくい部位を第２部品６２によって補強し、変形を抑制できる。 (7) The first member 52 that reinforces the wire holding member 41 is assembled to the wire holding member 41 by the assembling nut 67. Then, the second component 62 is provided on the wire holding portion 44 side of the assembly nut 67, and the portion of the wire holding member 41 that is difficult to be reinforced by the first member 52 can be reinforced by the second component 62 to suppress deformation. ..

（８）延設部５４の長手は水平方向及び奥行方向に延び、ワイヤ２１の長手方向が延びる上下方向とは異なる方向に延びている。よって、延設部５４をワイヤ２１の振れ方向に交差して配置させ、ワイヤ２１の振れによってワイヤ保持部材４１に発生した外力を支承しやすく、ワイヤ保持部材４１の変形を抑制できる。 (8) The length of the extending portion 54 extends in the horizontal direction and the depth direction, and extends in a direction different from the vertical direction in which the longitudinal direction of the wire 21 extends. Therefore, the extending portions 54 are arranged so as to intersect with each other in the swing direction of the wire 21, and the external force generated in the wire holding member 41 due to the swing of the wire 21 can be easily supported, and the deformation of the wire holding member 41 can be suppressed.

（９）保持構造は一対のワイヤ保持装置４０を備え、各ワイヤ保持装置４０は、布設具２０が備えるワイヤ２１のワイヤ中途部２１ａをそれぞれ保持する。このため、保持構造により、ワイヤ中途部２１ａを保持して、布設具２０の振れを抑制できる。その結果、布設経路Ｋに布設された配線・配管材Ｐの振れも抑制できる。 (9) The holding structure includes a pair of wire holding devices 40, and each wire holding device 40 holds a wire midway portion 21a of the wire 21 included in the laying tool 20. Therefore, the holding structure can hold the wire midway portion 21a and suppress the runout of the laying tool 20. As a result, the runout of the wiring / piping material P laid in the laying path K can be suppressed.

（１０）一対のワイヤ保持部材４１は、突出部４７が他方のワイヤ２１と反対側を向くように軸部４３から突出するように壁Ｗに設置されている。すなわち、一対のワイヤ保持部材４１は、各突出部４７が外に向けて突出するように壁Ｗに設置されている。このため、ワイヤ２１が振れたとき、突出部４７の先端にワイヤ２１が接触することを回避し、ワイヤ２１が損傷を受ける事を回避できる。 (10) The pair of wire holding members 41 are installed on the wall W so that the protruding portion 47 protrudes from the shaft portion 43 so as to face the opposite side of the other wire 21. That is, the pair of wire holding members 41 are installed on the wall W so that the protruding portions 47 project outward. Therefore, when the wire 21 swings, it is possible to prevent the wire 21 from coming into contact with the tip of the protruding portion 47 and to prevent the wire 21 from being damaged.

（１１）ワイヤ保持部４４において、空間部４６の内縁に沿って形成される仮想円Ｃの直径はワイヤ２１の直径より長い。そして、ワイヤ保持部４４の空間部４６にはワイヤ２１が遊挿され、ワイヤ２１の径方向に沿った空間部４６内でのワイヤ２１の移動が許容されている。例えば、ワイヤ２１が移動不能にワイヤ保持部４４に保持されている場合と比べて、ワイヤ２１の振れが発生した場合にワイヤ保持部材４１に作用する外力を低減できる。また、ワイヤ２１の微振動は、許容でき、大きな振れが発生した場合は、振れによって発生する外力によるワイヤ保持部材４１の変形を抑制しつつ、ワイヤ２１の振れを抑制できる。 (11) In the wire holding portion 44, the diameter of the virtual circle C formed along the inner edge of the space portion 46 is longer than the diameter of the wire 21. Then, the wire 21 is loosely inserted into the space portion 46 of the wire holding portion 44, and the wire 21 is allowed to move in the space portion 46 along the radial direction of the wire 21. For example, as compared with the case where the wire 21 is immovably held by the wire holding portion 44, the external force acting on the wire holding member 41 when the wire 21 swings can be reduced. Further, the slight vibration of the wire 21 is acceptable, and when a large runout occurs, the runout of the wire 21 can be suppressed while suppressing the deformation of the wire holding member 41 due to the external force generated by the runout.

（１２）ワイヤ保持部４４を形成するために先端棒状部４２ａを曲げる方向は雄ねじ４３ａの螺進方向と同じである。このため、ワイヤ保持部材４１を壁Ｗに固定する際、第１直線部４４ａと第２直線部４４ｃとの間の隙間にワイヤ２１を通過させた状態でワイヤ保持部材４１をアンカー部材６０に螺進すると、ワイヤ保持部４４にワイヤ２１を入り込ませることができる。その結果、壁Ｗへのワイヤ保持部材４１の固定と、ワイヤ保持部４４へのワイヤ２１の配置とをほぼ同時に行うことができ、保持構造の形成が容易となる。 (12) The direction in which the tip rod-shaped portion 42a is bent to form the wire holding portion 44 is the same as the screwing direction of the male screw 43a. Therefore, when the wire holding member 41 is fixed to the wall W, the wire holding member 41 is screwed onto the anchor member 60 in a state where the wire 21 is passed through the gap between the first straight line portion 44a and the second straight line portion 44c. As the wire advances, the wire 21 can be inserted into the wire holding portion 44. As a result, the wire holding member 41 can be fixed to the wall W and the wire 21 can be arranged to the wire holding portion 44 at almost the same time, and the holding structure can be easily formed.

（１３）組付部５５の貫通部５５ａは、組付部５５の一つの側縁から凹む形状である。このため、壁Ｗにワイヤ保持部材４１を固定した後であっても、ワイヤ保持部材４１の軸部４３に組付部５５を組付けることができる。例えば、貫通部５５ａを丸孔状に形成した場合には、軸部４３を組付部５５に挿通してワイヤ保持部材４１と第１部材５２とを一体化させる必要があり、ワイヤ保持部材４１の固定部４５をアンカー部材６０に螺合する際に、第１部材５２がワイヤ保持部材４１と連れ回りして邪魔になり、好ましくない。よって、貫通部５５ａを組付部５５の一つの側縁から凹ませる形状とすることで、第１部材５２が邪魔にならずにワイヤ保持部材４１を壁Ｗに固定する作業を行うことができる。 (13) The penetrating portion 55a of the assembling portion 55 has a shape recessed from one side edge of the assembling portion 55. Therefore, even after the wire holding member 41 is fixed to the wall W, the assembling portion 55 can be assembled to the shaft portion 43 of the wire holding member 41. For example, when the penetrating portion 55a is formed in a round hole shape, it is necessary to insert the shaft portion 43 into the assembling portion 55 to integrate the wire holding member 41 and the first member 52, and the wire holding member 41 When the fixing portion 45 of the above is screwed into the anchor member 60, the first member 52 rotates with the wire holding member 41 and becomes an obstacle, which is not preferable. Therefore, by making the penetrating portion 55a recessed from one side edge of the assembled portion 55, it is possible to perform the work of fixing the wire holding member 41 to the wall W without the first member 52 getting in the way. ..

（１４）第１部材５２は、組付部５５に係止凸部５５ｂを備え、第２部品６２は、支持片６３に係止凹部６３ｂを備える。そして、サポート部材５１では、係止凹部６３ｂに係止凸部５５ｂが入り込んでいる。ワイヤ保持部材４１にワイヤ２１からの外力が作用した際、係止凹部６３ｂに係止凸部５５ｂが係止することで、貫通部５５ａが開く方向への組付部５５の変形を抑制できる。したがって、係止凸部５５ｂ及び係止凹部６３ｂを設ける構成は、貫通部５５ａを組付部５５の一つの側縁から凹ませる形状において特に有効である。 (14) The first member 52 includes a locking convex portion 55b in the assembling portion 55, and the second component 62 includes a locking concave portion 63b in the support piece 63. Then, in the support member 51, the locking convex portion 55b is inserted into the locking concave portion 63b. When an external force from the wire 21 acts on the wire holding member 41, the locking convex portion 55b is locked to the locking concave portion 63b, so that the deformation of the assembled portion 55 in the direction in which the penetrating portion 55a opens can be suppressed. Therefore, the configuration in which the locking convex portion 55b and the locking concave portion 63b are provided is particularly effective in a shape in which the penetrating portion 55a is recessed from one side edge of the assembled portion 55.

なお、上記実施形態は以下のように変更してもよい。
○ 実施形態では、一対の第１部材５２は、それぞれ壁Ｗを正面から見た正面視において長手がワイヤ２１の外側に向けて延びているようにワイヤ保持部材４１が壁Ｗに架設されていた。しかし、第１部材５２の長手が延びる方向は、これに限らない。一対の第１部材５２のうち、いずれか一方又は両方は、ワイヤ２１の内側に向けて延びるように、ワイヤ保持部材４１と壁Ｗに架設されていてもよい。 The above embodiment may be changed as follows.
○ In the embodiment, in each of the pair of first members 52, the wire holding member 41 is erected on the wall W so that the length of the pair of first members 52 extends toward the outside of the wire 21 when the wall W is viewed from the front. .. However, the direction in which the length of the first member 52 extends is not limited to this. One or both of the pair of first members 52 may be erected on the wire holding member 41 and the wall W so as to extend inward of the wire 21.

この場合、布設具２０の外側に、障害物や壁面が存在する場合であっても、それら障害物や壁面に対し、第１部材５２を干渉させずにワイヤ保持装置４０を設置できる。
○ 図８に示すように、ワイヤ保持装置４０のサポート部材５１は、延設部５４が斜めに延びない構成であってもよい。この場合、延設部５４の内面５４ａがサポート部材用固定部５３の内面５３ａに直交し、延設部５４の外面５４ｂがサポート部材用固定部５３の外面５３ｂに直交するように第１部材５２が形成される。また、組付部５５は、延設部５４の長手方向に直交する方向へ突出するように延設部５４から延設されている。 In this case, even if an obstacle or a wall surface exists on the outside of the laying tool 20, the wire holding device 40 can be installed without interfering with the obstacle or the wall surface with the first member 52.
○ As shown in FIG. 8, the support member 51 of the wire holding device 40 may have a configuration in which the extending portion 54 does not extend diagonally. In this case, the first member 52 so that the inner surface 54a of the extension portion 54 is orthogonal to the inner surface 53a of the support member fixing portion 53 and the outer surface 54b of the extension portion 54 is orthogonal to the outer surface 53b of the support member fixing portion 53. Is formed. Further, the assembling portion 55 extends from the extending portion 54 so as to project in a direction orthogonal to the longitudinal direction of the extending portion 54.

サポート部材５１の第１部材５２は、長手方向の一端側に設けられて構造物に固定されるサポート部材用固定部５３と、ワイヤ保持部材４１の雄ねじ４３ａに螺着される一対の組付ナット６７に挟持されて軸部４３に組付けられる組付部５５とを備える。そして、組付部５５とサポート部材用固定部５３とは、ワイヤ保持部材４１の立設方向に沿って延びる延設部５４によって連結されている。したがって、延設部５４の長手は、ワイヤ保持部材４１の長手方向（立設方向）と同じ方向に延びている。さらに、サポート部材５１の第２部品６２は、組付ナット６７よりもワイヤ保持部４４側で、軸部４３の外面に当接する当接部として機能する。なお、図示しないが、組付部５５には係止凸部５５ｂが設けられるとともに、支持片６３には係止凹部６３ｂが設けられ、係止凹部６３ｂに係止凸部５５ｂが入り込んでいる。 The first member 52 of the support member 51 is a support member fixing portion 53 provided on one end side in the longitudinal direction and fixed to the structure, and a pair of assembling nuts screwed to the male screw 43a of the wire holding member 41. It is provided with an assembly portion 55 that is sandwiched between the 67 and assembled to the shaft portion 43. The assembling portion 55 and the support member fixing portion 53 are connected by an extending portion 54 extending along the vertical direction of the wire holding member 41. Therefore, the length of the extension portion 54 extends in the same direction as the length direction (erection direction) of the wire holding member 41. Further, the second component 62 of the support member 51 functions as a contact portion that abuts on the outer surface of the shaft portion 43 on the wire holding portion 44 side of the assembly nut 67. Although not shown, the assembly portion 55 is provided with a locking convex portion 55b, the support piece 63 is provided with a locking concave portion 63b, and the locking convex portion 55b is inserted into the locking concave portion 63b.

○ 図８に示すように、ワイヤ保持装置４０を建物の構造物としての形鋼材１０に設置してもよい。この場合、形鋼材１０の連結部１２に、当該連結部１２を貫通する孔１２ａをワイヤ保持部材４１の固定用と、第１部材５２の固定用に設ける。そして、連結部１２の孔１２ａを貫通した雄ねじ４３ａにナット６６を螺合し、軸部４３に螺着した固定用ナット４８とナット６６で構造物としての連結部１２を挟持して、ワイヤ保持部材４１が連結部１２に固定される。 ○ As shown in FIG. 8, the wire holding device 40 may be installed on the shaped steel material 10 as the structure of the building. In this case, the connecting portion 12 of the shaped steel material 10 is provided with a hole 12a penetrating the connecting portion 12 for fixing the wire holding member 41 and for fixing the first member 52. Then, the nut 66 is screwed into the male screw 43a penetrating the hole 12a of the connecting portion 12, and the connecting portion 12 as a structure is sandwiched between the fixing nut 48 and the nut 66 screwed to the shaft portion 43 to hold the wire. The member 41 is fixed to the connecting portion 12.

また、ワイヤ２１が天井Ｔに沿うように布設具２０が布設される場合は、ワイヤ保持装置４０を建物の構造物としての天井Ｔに設置して、ワイヤ保持装置４０によってワイヤ中途部２１ａの振れを抑制してもよい。 When the laying tool 20 is laid so that the wire 21 is along the ceiling T, the wire holding device 40 is installed on the ceiling T as a structure of the building, and the wire holding device 40 causes the wire middle portion 21a to run out. May be suppressed.

○ 建物の構造物は、実施形態のようなＩ形鋼ではなく、Ｃ形鋼（リップ形鋼）であってもよい。この場合、Ｃ形鋼を貫通させた軸部４３に、Ｃ形鋼の外側からナットを螺着し、軸部４３に螺着されたナット及び固定用ナット４８でＣ形鋼を挟持してワイヤ保持部材４１をＣ形鋼に固定してもよい。 ○ The structure of the building may be C-shaped steel (lip-shaped steel) instead of I-shaped steel as in the embodiment. In this case, a nut is screwed from the outside of the C-shaped steel to the shaft portion 43 through which the C-shaped steel is passed, and the C-shaped steel is sandwiched between the nut screwed to the shaft portion 43 and the fixing nut 48 to wire. The holding member 41 may be fixed to the C-shaped steel.

このように構成した場合、布設具２０の周囲にワイヤ保持装置４０を固定する構造物が存在しない場合は、布設具２０の周囲にＣ形鋼を設置し、そのＣ形鋼の溝を利用してワイヤ保持装置４０を設置できる。この場合、Ｃ形鋼の溝の延びる方向にワイヤ保持装置４０の設置範囲が広がり、ワイヤ保持装置４０の自由度が広がる。 In this configuration, if there is no structure for fixing the wire holding device 40 around the laying tool 20, C-shaped steel is installed around the laying tool 20 and the groove of the C-shaped steel is used. The wire holding device 40 can be installed. In this case, the installation range of the wire holding device 40 is widened in the direction in which the groove of the C-shaped steel extends, and the degree of freedom of the wire holding device 40 is widened.

○ 延設部５４によってワイヤ保持部材４１に作用する外力を支承することができれば、延設部５４は長手方向に沿って湾曲したり、屈曲したりしていてもよい。
○ 図９に示すように、ワイヤ保持部材４１に組付ける第１部材５２を複数とし、サポート部材５１は延設部５４を複数有する構成であってもよい。このように構成した場合、複数の延設部５４によってワイヤ保持部材４１を支承でき、ワイヤ保持部材４１の変形を抑制できる。また、重なり合う組付部５５同士では、下側の組付部５５から突出した係止凸部５５ｂが、上側の組付部５５において、係止凸部５５ｂを突出させるために下面から凹んだ部位に入り込んでいる。このように構成すると、複数の組付部５５において、貫通部５５ａの開口する方向が異なっている。しかし、ワイヤ保持部材４１にワイヤ２１からの外力が作用した際、組付部５５の凹みに係止凸部５５ｂが係止することで、貫通部５５ａが開く方向への組付部５５の変形を抑制できる。 ○ As long as the extension portion 54 can bear the external force acting on the wire holding member 41, the extension portion 54 may be curved or bent along the longitudinal direction.
○ As shown in FIG. 9, a plurality of first members 52 to be assembled to the wire holding member 41 may be provided, and the support member 51 may have a plurality of extending portions 54. With this configuration, the wire holding member 41 can be supported by the plurality of extending portions 54, and the deformation of the wire holding member 41 can be suppressed. Further, in the overlapping assembly portions 55, the locking convex portion 55b protruding from the lower assembly portion 55 is recessed from the lower surface in the upper assembly portion 55 in order to project the locking convex portion 55b. It's getting in. With this configuration, the opening directions of the penetrating portions 55a are different in the plurality of assembled portions 55. However, when an external force from the wire 21 acts on the wire holding member 41, the locking convex portion 55b is locked in the recess of the assembling portion 55, so that the assembling portion 55 is deformed in the direction in which the penetrating portion 55a opens. Can be suppressed.

○ 図１０に示すように、布設具２０は、１本のワイヤ２１のみを備える構成であってもよい。この場合、ワイヤ中途部２１ａの保持構造において、ワイヤ保持装置４０は、１本のワイヤ２１に対応して１つだけ壁Ｗに設置される。 ○ As shown in FIG. 10, the laying tool 20 may be configured to include only one wire 21. In this case, in the holding structure of the wire midway portion 21a, only one wire holding device 40 is installed on the wall W corresponding to one wire 21.

○ ワイヤ中途部２１ａの保持構造は、布設具２０の一対のワイヤ２１のうち、一方のワイヤ２１をワイヤ保持装置４０で保持し、他方のワイヤ２１は保持しない構成であってもよい。 The holding structure of the wire midway portion 21a may be such that one of the pair of wires 21 of the laying tool 20 is held by the wire holding device 40 and the other wire 21 is not held.

○ 一対のワイヤ保持部材４１において、いずれか一方の突出部４７又は両方の突出部４７が他方のワイヤ２１を向くように軸部４３から突出するように壁Ｗに設置されていてもよい。 ○ In the pair of wire holding members 41, one of the projecting portions 47 or both projecting portions 47 may be installed on the wall W so as to project from the shaft portion 43 so as to face the other wire 21.

○ ワイヤ保持部材４１において、突出部４７が軸部４３から突出しないように先端棒状部４２ａの長さを短くしてワイヤ保持部４４を形成してもよい。
○ 第１部材５２において、組付部５５の貫通部５５ａは、スリット状でなく、孔状であってもよい。 ○ In the wire holding member 41, the wire holding portion 44 may be formed by shortening the length of the tip rod-shaped portion 42a so that the protruding portion 47 does not protrude from the shaft portion 43.
○ In the first member 52, the penetrating portion 55a of the assembling portion 55 may have a hole shape instead of a slit shape.

○ 一対の組付ナット６７のうち、支持片６３の上面側に配置される組付ナット６７と、支持片６３との間にワッシャを設けてもよい。又は一対の組付ナット６７のうち、支持片６３の上面側に配置される組付ナット６７をフランジ付きナットとしてもよい。この場合、ワッシャ又はフランジは、支持片６３の係止凹部６３ｂを覆うことのできる大きさにするのがより好ましい。 ○ Of the pair of assembly nuts 67, a washer may be provided between the assembly nut 67 arranged on the upper surface side of the support piece 63 and the support piece 63. Alternatively, of the pair of assembly nuts 67, the assembly nut 67 arranged on the upper surface side of the support piece 63 may be a flanged nut. In this case, the washer or flange is more preferably sized so as to cover the locking recess 63b of the support piece 63.

ワイヤ保持部材４１にワイヤ２１からの外力が作用した際、第２部品６２の当接片６４には、当接片６４が支持片６３から離れるように変形させる力が作用する。すると、支持片６３が組付部５５から離れる虞がある。支持片６３が組付部５５から離れると、係止凹部６３ｂと係止凸部５５ｂとの係止が解除され、貫通部５５ａが開く方向に組付部５５が変形する虞がある。 When an external force from the wire 21 acts on the wire holding member 41, a force that deforms the contact piece 64 of the second component 62 so as to separate the contact piece 64 from the support piece 63 acts on the contact piece 64. Then, the support piece 63 may be separated from the assembly portion 55. When the support piece 63 is separated from the assembling portion 55, the locking recess 63b and the locking convex portion 55b are released from each other, and the assembling portion 55 may be deformed in the direction in which the penetrating portion 55a is opened.

そこで、係止凹部６３ｂを覆うワッシャ又はフランジを設けることで、第２部品６２に、当接片６４が支持片６３から離れるように変形させる力が作用しても、支持片６３の変形を抑制でき、係止凹部６３ｂと係止凸部５５ｂとが係止する状態を維持でき、組付部５５の変形を抑制できる。 Therefore, by providing a washer or a flange that covers the locking recess 63b, even if a force that deforms the contact piece 64 away from the support piece 63 acts on the second component 62, the deformation of the support piece 63 is suppressed. It is possible to maintain a state in which the locking concave portion 63b and the locking convex portion 55b are locked, and the deformation of the assembled portion 55 can be suppressed.

○ 実施形態では、支持片６３は軸部４３の雄ねじ４３ａに当接し、当接片６４は、雄ねじ４３ａのない第１直線部４４ａに当接していた。しかし、壁Ｗからのワイヤ２１の離間距離によってワイヤ保持部材４１のアンカー部材６０への螺合量が異なる場合には、支持片６３及び当接片６４が、軸部４３の雄ねじ４３ａに当接するし、支持片６３及び当接片６４が、第１直線部４４ａに当接する。 In the embodiment, the support piece 63 is in contact with the male screw 43a of the shaft portion 43, and the contact piece 64 is in contact with the first straight line portion 44a without the male screw 43a. However, when the screwing amount of the wire holding member 41 to the anchor member 60 differs depending on the separation distance of the wire 21 from the wall W, the support piece 63 and the contact piece 64 come into contact with the male screw 43a of the shaft portion 43. Then, the support piece 63 and the contact piece 64 come into contact with the first straight line portion 44a.

○ 実施形態では、組付部５５に係止凸部５５ｂを設け、支持片６３に係止凹部６３ｂを設けたが、組付部５５に係止凹部を設け、支持片６３に係止凸部を設けてもよい。
○ サポート部材５１において、第２部品６２を第１部材５２の組付部５５に溶接等によって一体化してもよい。 ○ In the embodiment, the assembling portion 55 is provided with the locking convex portion 55b and the support piece 63 is provided with the locking concave portion 63b. However, the assembling portion 55 is provided with the locking concave portion and the support piece 63 is provided with the locking convex portion. May be provided.
○ In the support member 51, the second component 62 may be integrated with the assembly portion 55 of the first member 52 by welding or the like.

○ サポート部材５１は、サポート部材用固定部５３と、延設部５４と、組付部５５と、組付部５５に一体の当接部と、を備える構成であってもよい。この場合、サポート部材５１の当接部は、長板５０の長手方向他端側において、組付部５５よりも先端側を折り返して形成する。 The support member 51 may be configured to include a fixing portion 53 for the support member, an extending portion 54, an assembling portion 55, and an abutting portion integrated with the assembling portion 55. In this case, the contact portion of the support member 51 is formed by folding back the tip end side of the assembly portion 55 on the other end side of the elongated plate 50 in the longitudinal direction.

○ ワイヤ保持部４４を形成する先端棒状部４２ａの周面に防振ゴム等の防振材を一体に設けてもよい。
○ ワイヤ保持部４４は、第１直線部４４ａと第２直線部４４ｃの間に隙間ができないように第１直線部４４ａに第２直線部４４ｃを接触させたり、溶接したりした状態であってもよい。 -An anti-vibration material such as anti-vibration rubber may be integrally provided on the peripheral surface of the tip rod-shaped portion 42a forming the wire holding portion 44.
○ The wire holding portion 44 is in a state in which the second straight portion 44c is brought into contact with or welded to the first straight portion 44a so that there is no gap between the first straight portion 44a and the second straight portion 44c. May be good.

○ ワイヤ保持部材４１の固定部４５は、雄ねじ４３ａでなくてもよい。例えば、軸部４３を平板状の固定片から立設させ、固定片を固定部とする。そして、固定片を貫通した固定ボルトを、構造物としての壁Ｗ、天井Ｔ等に埋設したアンカー部材６０に螺合する、又は構造物としての形鋼材１０を貫通させてナットによって固定してもよい。 ○ The fixing portion 45 of the wire holding member 41 does not have to be a male screw 43a. For example, the shaft portion 43 is erected from a flat plate-shaped fixing piece, and the fixing piece is used as the fixing portion. Then, even if the fixing bolt penetrating the fixing piece is screwed into the anchor member 60 embedded in the wall W, the ceiling T, etc. as the structure, or the shaped steel material 10 as the structure is passed through and fixed by the nut. good.
