Description
本発明は、ひし形金網を有するネットフェンス及びその製造方法に関する。 The present invention relates to a net fence having a diamond wire mesh and a method for manufacturing the same.
ネットフェンスは、安全や防犯等を目的として建物や公園等に設けられる。ネットフェンスとしては、ジグザグ状に屈曲させた複数の列線の屈曲部同士を互いに係合させてなる、いわゆるひし形金網を用いたものが広く知られている。 Net fences are installed in buildings and parks for the purpose of safety and crime prevention. As a net fence, what uses what is called a rhombus metal net | network formed by mutually making the bending part of the some line line bent in the zigzag shape mutually is known.
ネットフェンスに用いられるひし形金網は、通常、各列線の延在方向（以下、この方向を、ひし形金網の「幅方向」と言う。）が上下方向となるように設けられる。この場合、ひし形金網の幅方向両端に張線を挿通し、上下の胴縁に設けられた爪に張線を引っ掛けることで、ひし形金網が胴縁に取り付けられる（下記の特許文献１参照）。しかし、このような作業は容易ではなく、施工に手間がかかるという問題がある。 The diamond wire mesh used for the net fence is usually provided such that the extending direction of each column line (hereinafter, this direction is referred to as the “width direction” of the diamond wire mesh) is the vertical direction. In this case, the diamond wire mesh is attached to the trunk edge by inserting a tension wire through both ends of the diamond mesh in the width direction and hooking the tension wire on the claws provided on the upper and lower trunk edges (see Patent Document 1 below). However, such work is not easy, and there is a problem that construction takes time.
これに対し、下記の特許文献２では、ひし形金網の幅方向を水平方向としたネットフェンスが示されている。この場合、ひし形金網の、幅方向と直交する方向（以下、この方向を「長手方向」と言う。）の両端に胴縁が取り付けられる。ひし形金網は、長手方向で伸縮可能であるため、ひし形金網の長手方向両端に予め胴縁を取り付けて、輸送時や保管時には、ひし形金網を上下に縮めることで省スペース化を図ることができる。そして、施工時には、ひし形金網を長手方向に引き延ばして平面状に展開し、このパネルの一方の胴縁を、地面に立設された一対の支柱の上部に仮置きする。この状態で、一対の胴縁を、それぞれ支柱の所定位置にボルト等で固定することで、ネットフェンスが組み立てられる。この場合、施工現場で、ひし形金網に張線を挿通する作業や、張線を胴縁の爪に引っ掛ける作業が不要になるため、施工が容易になる。 On the other hand, in the following Patent Document 2, a net fence is shown in which the width direction of the rhombus metal mesh is a horizontal direction. In this case, body edges are attached to both ends of the rhombus metal mesh in a direction orthogonal to the width direction (hereinafter, this direction is referred to as “longitudinal direction”). Since the rhombus metal mesh can be expanded and contracted in the longitudinal direction, space can be saved by attaching a barrel edge to both ends of the rhombus metal mesh in advance and shrinking the rhombus metal mesh up and down during transportation and storage. At the time of construction, the rhombus is stretched in the longitudinal direction and developed into a flat shape, and one body edge of this panel is temporarily placed on the upper portion of a pair of support columns standing on the ground. In this state, the net fence is assembled by fixing the pair of trunk edges to predetermined positions of the columns with bolts or the like. In this case, it is not necessary to perform an operation of inserting a tension wire through the diamond wire mesh or an operation of hooking the tension wire on the nail of the trunk edge at the construction site, so that the installation is facilitated.
上記の特許文献２に示されているネットフェンスでは、図１４に示すように、上側の胴縁２０１のフランジ２０１ａと、ひし形金網２０２の上端に挿通された補強材２０３との間に、支柱２０４のフランジ２０４ａの上端を挿入することで、上側の胴縁２０１を支柱２０４に仮置きしている。しかし、このような仮置き作業は手間がかかると共に、上側の胴縁２０１の支持状態が不安定であるため、作業性が悪化する。 In the net fence shown in the above-mentioned Patent Document 2, as shown in FIG. 14, a support column 204 is provided between the flange 201 a of the upper trunk edge 201 and the reinforcing member 203 inserted through the upper end of the diamond wire mesh 202. The upper trunk edge 201 is temporarily placed on the support column 204 by inserting the upper end of the flange 204a. However, such temporary placement work is troublesome and the support state of the upper trunk edge 201 is unstable, so that workability is deteriorated.
そこで、本発明は、ひし形金網を有するネットフェンスの施工をさらに容易化することを目的とする。 Therefore, an object of the present invention is to further facilitate the construction of a net fence having a diamond wire mesh.
前記課題を解決するために、本発明は、一対の支柱と、前記一対の支柱の間に掛け渡され、上下方向に離間して設けられた一対の胴縁と、上端及び下端が前記一対の胴縁に取り付けられ、ジグザグ状に屈曲しながら前記胴縁の延在方向に延びる複数の列線の屈曲部同士を、前記支柱の延在方向に互いに係合させてなるひし形金網とを備えたネットフェンスであって、前記ひし形金網の上端に取り付けられた上側の胴縁が、前記ひし形金網の厚さ方向両側において、前記支柱により下方から支持されたネットフェンスを提供する。 In order to solve the above problems, the present invention provides a pair of struts, a pair of trunk edges that are spanned between the pair of struts and spaced apart in the vertical direction, and an upper end and a lower end are the pair of struts. A rhombus wire mesh attached to the trunk edge and bent in a zigzag manner and extending in the extending direction of the trunk edge to bend each other in the extending direction of the column. It is a net fence, Comprising: The upper trunk edge attached to the upper end of the said rhombus metal mesh provides the net fence supported from the downward direction by the said support | pillar in the thickness direction both sides of the said rhombus metal net.
上記のように、上側の胴縁が、ひし形金網の厚さ方向両側において、一対の支柱で下方から支持されることにより、ひし形金網の上端が取り付けられた上側の胴縁を、一対の支柱の上に安定した状態で仮置きすることができる。この場合、上側の胴縁を支柱の支持部の上に載置するだけで仮置きができるため、上記の特許文献２のように、胴縁のフランジと補強材との間に支柱のフランジを挿入する作業が不要となり、施工が容易化される。 As described above, the upper trunk edge is supported from below by a pair of struts on both sides in the thickness direction of the rhombus metal mesh, so that the upper trunk edge to which the upper end of the rhombus metal mesh is attached is It can be temporarily placed in a stable state. In this case, since temporary placement can be performed simply by placing the upper barrel edge on the support portion of the support column, the flange of the support column is provided between the flange of the barrel edge and the reinforcing material as in Patent Document 2 above. The work to insert becomes unnecessary, and the construction is facilitated.
上記のネットフェンスは、前記支柱が、前記厚さ方向で対向する一対の側面部を有し、前記支柱の一対の胴縁の間に、前記上側の胴縁の端部が嵌まり込んだ構成とすることができる。この場合、上側の胴縁を、支柱の一対の側面部の間に嵌め込みながら支柱の上に載置することができるため、より一層安定した状態で支柱に仮置きすることができる。 The net fence has a configuration in which the support column has a pair of side portions opposed to each other in the thickness direction, and an end portion of the upper trunk edge is fitted between the pair of trunk edges of the support column. It can be. In this case, since the upper trunk edge can be placed on the support while being fitted between the pair of side surfaces of the support, it can be temporarily placed on the support in a more stable state.
ところで、ひし形金網を用いたネットフェンスでは、人（特に子供）が網目に足を入れて上ってしまうことがある。例えば、ひし形金網の網目を細かくすれば、人の足が入りにくくなるが、この場合、列線の使用量が増えるため、コストが増大する。そこで、ひし形金網の網目の胴縁延在方向（横方向）のピッチを、支柱延在方向（縦方向）のピッチよりも小さくし、網目を縦長にすれば、列線の使用量を抑えながら、網目に人の足が入りにくくなる。 By the way, in a net fence using a diamond wire net, a person (especially a child) may go up with a foot in the net. For example, if the mesh of the rhombus metal mesh is made fine, it becomes difficult for human feet to enter, but in this case, the amount of use of the column lines increases, so the cost increases. Therefore, if the pitch in the trunk edge extending direction (lateral direction) of the mesh of the rhombus metal mesh is made smaller than the pitch in the column extending direction (vertical direction) and the mesh is made vertically long, the amount of column lines used is suppressed. , It becomes difficult for human feet to enter the mesh.
このとき、従来のひし形金網では、列線が縦方向に延びているため、網目を縦長にすると、列線の屈曲部のピッチが広がる。図１５に示すように、列線１１０は、ジラス１０１及びヘラ１０２を用いてジグザグ状に屈曲される（上記の特許文献３参照）。この場合、列線１１０の屈曲部のピッチが広がると、ヘラ１０２に巻き付けられる列線１１０の巻き付け回数が減るため、列線１１０がヘラ１０２の先端側（図中矢印方向）に送り出されにくくなり、列線１１０の成形に支障を来たすおそれがある。例えば、ジラス１０１及びヘラ１０２を長くすれば、ピッチの広い列線１１０を成形することができるが、この場合、成形装置全体の構造を変更する必要が生じるため、コストがかかる。 At this time, in the conventional rhombus metal mesh, the column lines extend in the vertical direction. Therefore, when the mesh is made vertically long, the pitch of the bent portions of the column lines increases. As shown in FIG. 15, the column line 110 is bent in a zigzag shape using the gusset 101 and the spatula 102 (see Patent Document 3 above). In this case, if the pitch of the bent portion of the column line 110 is widened, the number of windings of the column line 110 wound around the spatula 102 is reduced, so that the column line 110 is less likely to be sent to the tip side of the spatula 102 (arrow direction in the figure). There is a risk of hindering the formation of the column line 110. For example, if the girth 101 and the spatula 102 are lengthened, the row lines 110 having a wide pitch can be formed. However, in this case, it is necessary to change the structure of the entire forming apparatus, which is expensive.
これに対し、上記のひし形金網では、列線が横方向に延びているため、列線の屈曲部のピッチは、網目の横方向のピッチと等しくなる。従って、上記のように、網目の横方向のピッチを小さくすることで、各列線の屈曲部のピッチが小さくなるため、既存の設備（ジラス及びヘラ）を用いて列線をジグザグ状に成形して、縦長の網目を有するひし形金網を得ることができる。 On the other hand, in the above-described rhombus metal mesh, the column lines extend in the horizontal direction, so the pitch of the bent portions of the column lines is equal to the pitch in the horizontal direction of the mesh. Therefore, as described above, by reducing the horizontal pitch of the mesh, the pitch of the bent portion of each column line is reduced, so the column line is formed in a zigzag shape using existing equipment (jilas and spatula). Thus, a rhombus wire mesh having a vertically long mesh can be obtained.
従来のネットフェンスでは、ひし形金網を補強するために、ひし形金網の縦方向中間部に、横方向に直線状に延びる張線が設けられる。これに対し、本発明のネットフェンスでは、ひし形金網の列線が横方向に延びているため、各列線が横方向の張線のような役割を果たすことができる。これにより、ひし形金網（特に、胴縁及び支柱で囲まれた領域）に、横方向に直線状に延びる張線を設けなくて済むため、コスト低減が図られると共に、外観が改善される。 In the conventional net fence, in order to reinforce the rhombus metal mesh, a tension line extending linearly in the horizontal direction is provided in the longitudinal middle portion of the rhombus metal mesh. On the other hand, in the net fence according to the present invention, the column lines of the rhombus metal mesh extend in the horizontal direction, so that each column line can function as a horizontal tension line. This eliminates the need to provide a stretched wire extending in a horizontal direction in the rhombus wire mesh (particularly, the region surrounded by the trunk edge and the column), thereby reducing costs and improving the appearance.
以上のように、本発明によれば、上側の胴縁を支柱に仮置きする際の作業性が向上するため、ネットフェンスの施工が容易化される。 As described above, according to the present invention, workability at the time of temporarily placing the upper trunk edge on the support column is improved, so that the construction of the net fence is facilitated.
以下、本発明の実施の形態を図面に基づいて説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

A fixing hole 3 c 1 for fixing to the support column 2 is provided in the side surface portion 3 c of the upper trunk edge 3. As shown in FIG. 4, in the state where the bottom surface portion 3 a of the upper trunk edge 3 is supported from below by the upper end 2 a 2 of the inner surface portion 2 a of the support column 2, The fixing hole 2c1 of the side surface part 2c is fixed with a bolt 7.
下胴縁４は、図５に示すように、水平方向に延びる角筒状を成し、おおよそ上胴縁３を上下反転させた構成を有している。具体的に、下胴縁４は、フェンス厚さ方向に対向する一対の側面部４ｃと、一対の側面部４ｃの上端からフェンス厚さ方向内側に延びる一対の上面部４ａと、一対の側面部４ｃの下端同士を連結する底面部４ｂとを備える。一対の上面部４ａの間には、横方向に延びる開口部４ａ１が設けられる。下胴縁４の底面部４ｂには、横方向に離間した複数箇所に設けられた水抜き穴４ｂ１と、横方向端部付近に設けられた固定穴４ｂ２とが設けられる。下胴縁４の側面部４ｃは、穴の無い平板状を成している。下胴縁４の横方向の寸法は、上胴縁３よりも若干短く、一対の支柱２の間隔よりも僅かに小さい。図６に示すように、下胴縁４の底面部４ｂがＬ字金具８の水平部８ａに固定され、支柱２の内面部２ａがＬ字金具８の垂直部８ｂに固定される。これにより、下胴縁４の端部が、Ｌ字金具８を介して支柱２に固定される。 As shown in FIG. 5, the lower trunk edge 4 has a rectangular tube shape extending in the horizontal direction, and has a configuration in which the upper trunk edge 3 is roughly inverted up and down.

As shown in FIG. 6, the bottom surface portion 4 b of the lower trunk edge 4 is fixed to the horizontal portion 8 a of the L-shaped metal fitting 8, and the inner surface portion 2 a of the support column 2 is fixed to the vertical portion 8 b of the L-shaped metal fitting 8. Thereby, the end of the lower trunk edge 4 is fixed to the support column 2 via the L-shaped metal fitting 8.
ひし形金網５は、図７に示すように、ジグザグ状に屈曲しながら横方向に延びる複数の列線５ａで構成される。各列線５ａの屈曲部５ａ１は、隣接する列線５ａの屈曲部５ａ１と縦方向に係合している。ひし形金網５の横方向両端部では、図８に示すように、隣接する列線５ａの端部が、互いに交差した状態で略１８０°折り返され、これにより列線５ａの端部同士の結合部Ｐが形成される（このような結合部Ｐを「完全ナックル」と言う）。このように、隣接する列線５ａの端部同士を結合することで、施工時等にひし形金網５を伸縮させる際に列線５ａ同士が外れることがなく、扱いやすい。 As shown in FIG. 7, the rhombus wire mesh 5 is composed of a plurality of column lines 5a extending in the lateral direction while being bent in a zigzag shape. The bent portion 5a1 of each column line 5a is engaged with the bent portion 5a1 of the adjacent column line 5a in the vertical direction. As shown in FIG. 8, at the both ends in the lateral direction of the rhombus metal mesh 5, the end portions of the adjacent column lines 5a are folded back approximately 180 ° in a state of crossing each other, thereby joining the end portions of the column lines 5a. P is formed (such a joint P is referred to as a “complete knuckle”). In this way, by joining the ends of the adjacent column lines 5a, the column lines 5a are not detached when the rhombus wire mesh 5 is expanded and contracted at the time of construction or the like, which is easy to handle.
図７に示すように、ひし形金網５の網目の横方向のピッチＬ１は、縦方向のピッチＬ２よりも短い。具体的には、網目の横方向のピッチＬ１と縦方向のピッチＬ２との比Ｌ２／Ｌ１が１．５以上、好ましくは２以上とされる。このように、網目の横方向のピッチＬ１を小さくして網目を縦長形状にすることで、人の足が入りにくくなり、人がネットフェンスに上ることを防止できる。このとき、網目の横方向のピッチＬ１及び縦方向のピッチＬ２を共に小さくすると、列線５ａの使用量が増えて、コスト及び重量が増大するため、横方向のピッチＬ１を小さくすると同時に、縦方向のピッチＬ２を大きくすることが好ましい。本実施形態では、各列線５ａが横方向に延びているため、各列線５ａの屈曲部５ａ１のピッチ（山−山間あるいは谷−谷間のピッチ）は、網目の横方向のピッチＬ１と等しい。従って、上記のようにひし形金網５の網目の縦方向のピッチＬ２を大きくした場合でも、各列線５ａの屈曲部５ａ１のピッチは小さいため、既存の装置を用いて列線５ａを屈曲成形することができる。 As shown in FIG. 7, the horizontal pitch L1 of the mesh of the rhombus metal mesh 5 is shorter than the vertical pitch L2. Specifically, the ratio L2 / L1 between the horizontal pitch L1 and the vertical pitch L2 of the mesh is 1.5 or more, preferably 2 or more. Thus, by making the pitch L1 in the horizontal direction of the mesh small and making the mesh vertically long, it becomes difficult for a person's foot to enter and it is possible to prevent the person from climbing the net fence. At this time, if both the horizontal pitch L1 and the vertical pitch L2 of the mesh are reduced, the amount of use of the column lines 5a is increased, and the cost and weight are increased. It is preferable to increase the direction pitch L2. In the present embodiment, since each column line 5a extends in the horizontal direction, the pitch (between mountain-mountain or valley-valley pitch) of the bent portion 5a1 of each column line 5a is equal to the horizontal pitch L1 of the mesh. . Accordingly, even when the pitch L2 in the longitudinal direction of the mesh of the rhombus metal mesh 5 is increased as described above, the pitch of the bent portions 5a1 of each column line 5a is small, so that the column line 5a is bent using an existing apparatus. be able to.
ひし形金網５の上端には、係合部材を介して上胴縁３が取り付けられる。係合部材としては、例えば図９（Ａ）（Ｂ）に示すようなコイル６が用いられる。コイル６は、螺旋状に巻回した鋼線からなる。コイル６のピッチは、ひし形金網５の列線５ａの屈曲部５ａ１のピッチと等しい。コイル６のフェンス厚さ方向の幅は、上胴縁３の開口部３ａ１の幅よりも大きい。コイル６が、ひし形金網５の上端の列線５ａの屈曲部５ａ１に挿通されると共に、上胴縁３の底面部３ａと上下方向で係合することで、ひし形金網５がコイル６を介して上胴縁３に吊り下げ保持される。 The upper trunk edge 3 is attached to the upper end of the rhombus metal mesh 5 via an engaging member. As the engaging member, for example, a coil 6 as shown in FIGS. 9A and 9B is used. The coil 6 is made of a steel wire wound spirally. The pitch of the coils 6 is equal to the pitch of the bent portions 5 a 1 of the column lines 5 a of the rhombus metal mesh 5. The width of the coil 6 in the fence thickness direction is larger than the width of the opening 3 a 1 of the upper trunk edge 3. The coil 6 is inserted into the bent portion 5 a 1 of the row line 5 a at the upper end of the rhombus metal mesh 5 and is engaged with the bottom surface portion 3 a of the upper trunk edge 3 in the vertical direction so that the rhombus metal mesh 5 is interposed via the coil 6. It is suspended and held on the upper trunk edge 3.

次に、ネットフェンス１の製造方法（施工方法）を説明する。 Next, the manufacturing method (construction method) of the net fence 1 will be described.
まず、金網製造工場において、図１１（Ａ）に示すように、所定の幅方向寸法及び長手方向寸法を有するひし形金網５を形成する。ひし形金網５は、網目の幅方向寸法Ｌ１が長手方向寸法Ｌ２よりも小さい（図７参照）。この場合、各列線５ａのピッチが小さくなるため、既存の装置を用いて、縦長の網目を有するひし形金網５を成形することができる。また、この装置により、ひし形金網５の幅方向両端に、列線５ａ同士の結合部Ｐ（図８参照）が形成される。 First, as shown in FIG. 11 (A), a diamond wire mesh 5 having predetermined width direction dimensions and longitudinal direction dimensions is formed in a wire mesh manufacturing factory. The rhombus wire mesh 5 has a mesh width direction dimension L1 smaller than a longitudinal direction dimension L2 (see FIG. 7). In this case, since the pitch of each column line 5a becomes small, the rhombus metal mesh 5 having a vertically long mesh can be formed using an existing apparatus. In addition, by this apparatus, the connecting portions P (see FIG. 8) between the column lines 5a are formed at both ends in the width direction of the rhombus metal mesh 5.
次に、図１１（Ｂ）に示すように、ひし形金網５の長手方向両端に上胴縁３及び下胴縁４を取り付けて、伸縮パネル１０を形成する。具体的には、図９及び図１０に示すように、ひし形金網５の長手方向両端の列線５ａの屈曲部５ａ１にコイル６を挿通し、各コイル６を上胴縁３及び下胴縁４の内周に挿入することで、ひし形金網５の長手方向両端に上胴縁３及び下胴縁４が取り付けられる。 Next, as shown in FIG. 11 (B), the upper trunk edge 3 and the lower trunk edge 4 are attached to both ends of the rhombus wire mesh 5 in the longitudinal direction to form the stretchable panel 10. Specifically, as shown in FIGS. 9 and 10, the coils 6 are inserted into the bent portions 5 a 1 of the row lines 5 a at both ends in the longitudinal direction of the rhombus metal mesh 5, and each coil 6 is connected to the upper trunk edge 3 and the lower trunk edge 4. The upper body edge 3 and the lower body edge 4 are attached to both ends of the rhombus wire mesh 5 in the longitudinal direction.
本実施形態では、ひし形金網５の幅方向（列線５ａの延在方向）と、胴縁３，４の延在方向とが平行であるため、図１１（Ｃ）に示すように、ひし形金網５を長手方向に縮めながら胴縁３，４を接近させて、伸縮パネル１０をコンパクトに収納することができる。これにより、伸縮パネル１０の輸送時や保管時のスペースが縮小されるため、輸送コスト及び保管コストを低減することができる。 In this embodiment, since the width direction of the rhombus metal mesh 5 (extending direction of the row line 5a) and the extending direction of the trunk edges 3 and 4 are parallel, as shown in FIG. The telescopic panel 10 can be accommodated in a compact manner by bringing the body edges 3 and 4 closer to each other while shrinking 5 in the longitudinal direction. Thereby, since the space at the time of transportation and storage of the elastic panel 10 is reduced, the transportation cost and the storage cost can be reduced.
次に、施工現場において、設置面に複数の支柱２を立設する。本実施形態では、図１２に示すように、複数のネットフェンス１が横方向に連結して使用される。この場合、複数のネットフェンス１の連結部に設けられる支柱２は、図２（Ｃ）に点線で示すように、外面部２ｂ同士がリベット等により結合される。複数のネットフェンス１の両端に設けられる支柱２は、単体で使用される。 Next, a plurality of support columns 2 are erected on the installation surface at the construction site. In the present embodiment, as shown in FIG. 12, a plurality of net fences 1 are connected in the horizontal direction. In this case, as for the support | pillar 2 provided in the connection part of the some net fence 1, outer surface part 2b is couple | bonded by a rivet etc. as shown with a dotted line in FIG.2 (C). The support | pillar 2 provided in the both ends of the some net fence 1 is used alone.
そして、伸縮パネル１０を上下に引き延ばして展開しながら、上胴縁３を一対の支柱２の上部に仮置きする。具体的には、図９（Ａ）に示すように、支柱２の一対の側面部２ｃの間に上胴縁３の端部を嵌め込みながら、支柱２の内面部２ａの上端２ａ２（支持部）の上に上胴縁３の底面部３ａを載置する。このとき、上胴縁３のうち、ひし形金網５のフェンス厚さ方向両側に設けられた底面部３ａが、支柱２の内面部２ａの上端２ａ２で支持されるため、上胴縁３が安定した状態で支持される。特に、図示例では、上胴縁３が、支柱２の側面部２ｃの間に嵌まり込むことで、上胴縁３がフェンス厚さ方向で位置決めされるため、上胴縁３がより一層安定した状態で支持される。このように、本実施形態では、上胴縁３を、一対の支柱２の上部に載置するだけで、伸縮パネルを一対の支柱２に容易かつ安定的に仮置きすることができる。 Then, the upper trunk edge 3 is temporarily placed on top of the pair of support columns 2 while the elastic panel 10 is extended up and down and deployed. Specifically, as shown in FIG. 9A, the upper end 2a2 (supporting portion) of the inner surface portion 2a of the support column 2 is fitted while the end portion of the upper trunk edge 3 is fitted between the pair of side surface portions 2c of the support column 2. The bottom portion 3a of the upper trunk edge 3 is placed on the top. At this time, since the bottom surface portions 3a provided on both sides of the rhombus metal mesh 5 in the fence thickness direction are supported by the upper end 2a2 of the inner surface portion 2a of the support column 2, the upper body edge 3 is stabilized. Supported in state. In particular, in the illustrated example, the upper trunk edge 3 is positioned in the fence thickness direction by fitting the upper trunk edge 3 between the side surface portions 2c of the support column 2, so that the upper trunk edge 3 is further stable. It is supported in the state. As described above, in the present embodiment, the elastic panel can be easily and stably temporarily placed on the pair of struts 2 simply by placing the upper trunk edge 3 on top of the pair of struts 2.
こうして上胴縁３を支柱２の上部に仮置きした状態で、上胴縁３を支柱２の上部にボルト７で固定する（図４参照）。その後、下胴縁４を、Ｌ字金具８を介して、支柱２の下部にボルト７で固定する（図６及び図１０参照）。このとき、下胴縁４を下方に引き下げて、ひし形金網５を下方に引っ張った状態で、下胴縁４を支柱２に固定することで、ひし形金網５をきれいに張ることができる。 In this manner, with the upper trunk edge 3 temporarily placed on the upper part of the column 2, the upper trunk edge 3 is fixed to the upper part of the column 2 with the bolt 7 (see FIG. 4). Thereafter, the lower trunk edge 4 is fixed to the lower portion of the support column 2 with the bolt 7 via the L-shaped metal fitting 8 (see FIGS. 6 and 10). At this time, the rhombus metal mesh 5 can be neatly stretched by fixing the lower drum edge 4 to the support column 2 while lowering the lower drum edge 4 downward and pulling the rhombus metal mesh 5 downward.
その後、支柱２の内部に挿入されたひし形金網５の横方向両端部を、支柱２に固定する。本実施形態では、図８に示すように、支柱２をフェンス厚さ方向に貫通するボルト７を設け、このボルト７と、ひし形金網５の列線５ａの端部同士の結合部Ｐ（完全ナックル）とを横方向で係合させることで、ひし形金網５の横方向端部が支柱２に固定される。以上により、ネットフェンス１が完成する。 Thereafter, both ends in the lateral direction of the rhombus metal mesh 5 inserted into the support 2 are fixed to the support 2. In this embodiment, as shown in FIG. 8, a bolt 7 that penetrates the support column 2 in the fence thickness direction is provided, and a connecting portion P (complete knuckle) between this bolt 7 and the ends of the row wire 5 a of the rhombus metal mesh 5. ) In the lateral direction, the lateral end of the rhombus metal mesh 5 is fixed to the column 2. Thus, the net fence 1 is completed.
本発明は上記の実施形態に限られない。例えば、ひし形金網５の上端と上胴縁３とを結合する係合部材は、上記のコイル６に限られない。例えば、係合部材として、図１３（Ａ）（Ｂ）に示すように、横方向に延びる棒材１１と、横方向複数箇所に設けられたボルト１２とを用いることができる。棒材１１は、ひし形金網５の上端の列線５ａに挿通され、この列線５ａを下方から支持する。ボルト１２は、上胴縁３をフェンス厚さ方向に貫通し、棒材１１を下方から支持する。これにより、ひし形金網５の上端が、棒材１１及びボルト１２を介して、上胴縁３に取り付けられる。 The present invention is not limited to the above embodiment. For example, the engaging member that connects the upper end of the rhombus metal mesh 5 and the upper trunk edge 3 is not limited to the coil 6 described above. For example, as shown in FIGS. 13A and 13B, a bar 11 extending in the horizontal direction and bolts 12 provided at a plurality of positions in the horizontal direction can be used as the engaging member. The bar 11 is inserted through the row line 5a at the upper end of the rhombus 5 and supports the row line 5a from below. The bolt 12 penetrates the upper trunk edge 3 in the fence thickness direction, and supports the bar 11 from below. Thereby, the upper end of the rhombus metal mesh 5 is attached to the upper trunk edge 3 via the bar 11 and the bolt 12.
また、上記の実施形態では、ひし形金網５の網目が縦長形状である場合を示したが、これに限らず、例えば、各編目を略正方形としてもよい。 In the above-described embodiment, the case where the mesh of the rhombus metal mesh 5 has a vertically long shape is shown.
