Abstract
Description
本発明は、歩道と道路との境界や敷地境界等に設置される防護柵であって、特に勾配のある場所への設置に適した防護柵に関するものである。 The present invention relates to a protective fence that is installed at a boundary between a sidewalk and a road, a boundary of a site, and the like, and particularly relates to a protective fence that is suitable for installation in a sloped place.
図１２（Ａ）、（Ｂ）には、従来の防護柵の断面構造が例示されている。この従来の防護柵５０は、上下一対の胴縁５１と、両胴縁５１間を連結する縦格子パネル５２と、を備えている。胴縁５１にはその全長に亘ってスリット５１ｓが形成されている。胴縁５１は金属板を曲げ加工してスリット５１ｓを有する筒状体を形成するとともに、その金属板の曲げ方向両端部を互いに平行に筒状体の内側に屈曲させて縦格子パネル支持部５３を形成してなる。縦格子パネル５２は、胴縁５１の長手方向（紙面に対し垂直方向）に並設される複数本の縦格子５４と、隣り合う縦格子５４同士の間隔を等間隔に保持する間隔保持材５５とを有している。縦格子５４の上下両端には扁平部５４ａが形成され、各扁平部５４ａにリベット挿通孔５４ｂが形成されている。間隔保持材５４ｂは、細長い金属板を曲げ加工することにより、その長手方向に対し直交する断面形状がＬ字形をなすように成型された部材であり、縦部５５ａと横部５５ｂとを有している。間隔保持材５５は、互いの縦部５５ａを背中合わせにした姿勢で、縦格子５４の扁平部５４ａを挟むようにして、縦格子パネル５２の上端と下端に２本ずつ設けられている。間隔保持材５５の縦部５５ａには、その長手方向に等間隔に複数のリベット挿通孔５５ｃが形成されている。間隔保持材５５と縦格子５４は、互いのリベット挿通孔５５ｃ、５４ｂが連通するように重ね合わせた状態で、両リベット挿通孔５５ｃ、５４ｂにリベット６５を挿通してかしめることにより互いに回動可能に連結されている。胴縁５１の縦格子パネル５２への取り付けは、間隔保持材５５を胴縁５１内にスライドさせて挿入することによりなされる。 12A and 12B illustrate a cross-sectional structure of a conventional protective fence. The conventional protective fence 50 includes a pair of upper and lower body edges 51 and a vertical lattice panel 52 that connects the body edges 51 together. A slit 51s is formed in the trunk edge 51 over the entire length thereof. The body edge 51 is formed by bending a metal plate to form a cylindrical body having slits 51 s, and both ends of the metal plate in the bending direction are bent in parallel to each other inside the cylindrical body to support the vertical lattice panel support 53. Formed. The vertical lattice panel 52 includes a plurality of vertical lattices 54 arranged in parallel in the longitudinal direction of the trunk edge 51 (perpendicular to the paper surface) and a spacing member 55 that keeps the spacing between adjacent vertical lattices 54 at equal intervals. And have. Flat portions 54a are formed at both upper and lower ends of the vertical lattice 54, and rivet insertion holes 54b are formed in the respective flat portions 54a. The spacing member 54b is a member formed by bending an elongated metal plate so that a cross-sectional shape orthogonal to the longitudinal direction forms an L shape, and has a vertical portion 55a and a horizontal portion 55b. ing. Two spacing members 55 are provided at the upper end and the lower end of the vertical lattice panel 52 so that the flat portions 54a of the vertical lattice 54 are sandwiched in a posture in which the vertical portions 55a are back to back. A plurality of rivet insertion holes 55 c are formed at equal intervals in the longitudinal direction of the vertical portion 55 a of the spacing member 55. The spacing member 55 and the vertical lattice 54 rotate with each other by caulking the rivet 65 through the rivet insertion holes 55c and 54b in a state where the rivet insertion holes 55c and 54b are overlapped with each other. Connected as possible. The trunk edge 51 is attached to the vertical lattice panel 52 by sliding the spacing member 55 into the trunk edge 51 and inserting it.
しかし、上述した従来の防護柵では、図１２（Ａ）、（Ｂ）の例のように胴縁５１のスリット５１ｓの間隔よりも縦格子５４の扁平部５４ａの厚さが小さい場合、スリット５１ｓの両側に形成された縦格子パネル支持部５３と縦格子５４の扁平部５４ａとの間に隙間ｄ１、ｄ２が生じ、胴縁５１と縦格子５４との間にガタ付きが生じる原因となる。このガタ付きを防止するために、図１２（Ａ）、（Ｂ）の例では、胴縁５１と縦格子５４との隙間ｄ１、ｄ２方向への相対変位を間隔保持材５５によって規制しているが、縦格子５４の扁平部５４ａの厚さによって横部５５ｂの寸法Ｌ１、Ｌ２の異なる複数種類の間隔保持材５５を使用する必要がある。 However, in the above-described conventional guard fence, when the thickness of the flat portion 54a of the vertical lattice 54 is smaller than the interval of the slits 51s of the trunk edge 51 as in the example of FIGS. 12A and 12B, the slits 51s. The gaps d1 and d2 are generated between the vertical lattice panel support portions 53 formed on both sides of the flat plate 54 and the flat portions 54a of the vertical lattice 54, which causes backlash between the trunk edge 51 and the vertical lattice 54. In order to prevent this rattling, in the example of FIGS. 12A and 12B, the relative displacement in the gaps d1 and d2 direction between the trunk edge 51 and the vertical lattice 54 is regulated by the spacing member 55. However, it is necessary to use a plurality of types of spacing members 55 having different dimensions L1 and L2 of the horizontal portion 55b depending on the thickness of the flat portion 54a of the vertical lattice 54.
また、縦格子パネル５２は、間隔保持材５５の横部５５ｂを胴縁５１に形成された縦格子パネル支持部５３の端部に載せた状態で支持されるのみのため、製品誤差や施工誤差等により縦格子パネル５２と胴縁スリット５３ｓとの間に位置ずれが生じ、美観の低下や強度上の不安感を歩行者等に与えていた。 Further, since the vertical lattice panel 52 is only supported in a state where the horizontal portion 55b of the spacing member 55 is placed on the end portion of the vertical lattice panel support portion 53 formed on the trunk edge 51, a product error or a construction error is caused. As a result, a positional shift occurs between the vertical lattice panel 52 and the trunk edge slit 53s, giving a pedestrian and the like a decrease in aesthetics and anxiety in strength.
本発明が解決しようとする課題は、縦格子の端部の厚さによらず、同一種類の間隔保持材を使用して上下の胴縁間に縦格子を安定かつ強固に保持可能な構造を有する防護柵を提供することにある。 The problem to be solved by the present invention is to provide a structure capable of stably and firmly holding the vertical grid between the upper and lower body edges using the same type of spacing member regardless of the thickness of the end of the vertical grid. It is to provide a protective fence having.
上記課題を解決するために、本発明の防護柵は、
上下一対の胴縁と、両胴縁を連結する縦格子パネルと、を有し、
前記胴縁は、
その長手方向に全長に亘って延びる一定幅のスリットを有する筒状体であり、当該スリットの両縁から内側に向かって逆くさび状に拡開した縦格子パネル支持部を有しており、
両胴縁が互いのスリット同士を対向させて互いに平行に配置されており、
前記縦格子パネルは、
前記胴縁の長手方向に並設される複数の縦格子と、
当該縦格子の並び間隔を等間隔に保持するとともに、当該縦格子を互いに平行な姿勢に保ちつつ前記スリットの延びる方向に回動可能に保持する間隔保持材と、を有し、
前記間隔保持材は、
前記縦格子の端部と互いに連結された縦格子保持部と、
前記縦格子パネル支持部にくさび状に係合する胴縁係合部と、を有していることを特徴としている。
In order to solve the above problems, the protective fence of the present invention is:
A pair of upper and lower body edges, and a vertical grid panel connecting both body edges,
The trunk edge is
It is a cylindrical body having a slit with a constant width extending over the entire length in the longitudinal direction, and has a vertical lattice panel support that is expanded in a reverse wedge shape from both edges of the slit toward the inside,
Both trunk edges are arranged in parallel with each other facing each other's slits,
The vertical lattice panel is
A plurality of vertical lattices juxtaposed in the longitudinal direction of the trunk edge;
An interval holding material that holds the vertical grids at equal intervals, and holds the vertical grids in a parallel orientation with each other so as to be rotatable in the direction in which the slits extend.
The spacing material is
Vertical lattice holders connected to the ends of the vertical lattices;
It has a trunk edge engaging part engaged with the vertical lattice panel support part in the shape of a wedge.
上記構成によれば、縦格子パネルの間隔保持材が胴縁の縦格子パネル支持部にくさび状に係合するため、縦格子の端部の厚さによらず、同一種類の間隔保持材を使用して上下の胴縁間に縦格子を安定かつ強固に保持可能である。すなわち、防護柵によって使用する縦格子の端部の厚さが異なる場合でも、逆くさび状に形成された縦格子パネル支持部とくさび状に形成された間隔保持材の係合部との互いの係合の度合いがくさび機能によって変化することによって当該厚さの差分を吸収し、胴縁と縦格子との間のガタ付きを防止できる。 According to the above configuration, since the spacing member of the vertical grid panel engages with the vertical grid panel support part of the trunk edge in a wedge shape, the same type of spacing material is used regardless of the thickness of the end of the vertical grid. It can be used to hold the vertical lattice between the upper and lower body edges stably and firmly. That is, even when the thickness of the end portion of the vertical lattice used by the protective fence is different, the vertical lattice panel support portion formed in the reverse wedge shape and the engaging portion of the spacing member formed in the wedge shape are mutually connected. By changing the degree of engagement by the wedge function, the difference in thickness can be absorbed, and rattling between the trunk edge and the vertical lattice can be prevented.
また、縦格子パネルの自重により、間隔保持材の係合部が胴縁の支持部に押圧され、くさび機能がより発揮されるため、ボルトなどの特別な手段を用いずに全体的な剛性を向上することができる。 In addition, because the vertical lattice panel's own weight pushes the engaging part of the spacing member against the support part of the trunk edge, the wedge function is more exerted, so the overall rigidity can be increased without using special means such as bolts. Can be improved.
本発明の防護柵において、
前記縦格子パネル支持部は、
前記スリットの幅方向中心に関して対称に配置され、
前記係合部は、
前記縦格子の端部の厚さ方向中心に関して対称に配置されていることが望ましい。

The vertical lattice panel support is
Arranged symmetrically with respect to the center of the slit in the width direction,
The engaging portion is
It is desirable that the end portions of the vertical lattices are arranged symmetrically with respect to the thickness direction center.
上記構成によれば、縦格子パネルの間隔保持材が胴縁の縦格子パネル支持部にくさび状に係合することにより、何ら調整作業を要することなく、全ての縦格子がスリットの幅方向中心に配置される。 According to the above configuration, the vertical grid panel spacing member engages with the vertical grid panel support on the trunk edge like a wedge, so that all vertical grids are centered in the width direction of the slit without any adjustment work. Placed in.
本発明の防護柵において、
前記間隔保持材は、
上下に延びる縦格子保持部と、当該縦格子保持部の一方の長縁部から折り曲げられて斜めに延びる前記胴縁係合部とを有し、
互いに対を成す間隔保持材が、互いの縦格子保持部を背中合わせにした姿勢で、前記縦格子の端部を挟んで設けられていることが望ましい。
In the protective fence of the present invention,
The spacing material is

It is desirable that the interval holding members that are paired with each other are provided so as to sandwich the end portions of the vertical lattices in such a posture that the vertical lattice holding portions are back to back.
前記間隔保持材は、平面視千鳥状に配置されてもよい。 The spacing members may be arranged in a zigzag shape in plan view.
また、前記縦格子の端部を挟む一方の側に、前記胴縁の略全長に亘って延びる間隔保持材を設け、他方の側に、当該間隔保持材よりも短寸の複数の間隔保持材を互いに間隔をおいて設けてもよい。 Further, a spacing member that extends over substantially the entire length of the trunk edge is provided on one side across the end of the vertical lattice, and a plurality of spacing members that are shorter than the spacing member are provided on the other side. May be provided at intervals.
本発明によれば、縦格子パネルの間隔保持材が胴縁の縦格子パネル支持部にくさび状に係合する構造を採用したことにより、縦格子の端部の厚さによらず、同一種類の間隔保持材を使用して上下の胴縁間に縦格子を安定に保持可能な防護柵を提供することができる。 According to the present invention, by adopting a structure in which the vertical lattice panel spacing member is engaged in a wedge shape with the vertical lattice panel support portion of the trunk edge, the same type is used regardless of the thickness of the end portion of the vertical lattice. Thus, a protective fence capable of stably holding the vertical grid between the upper and lower body edges can be provided.
以下、本発明を実施するための最良の形態について説明する。 Hereinafter, the best mode for carrying out the present invention will be described.
図１は本発明の防護柵の実施形態を示す要部正面図である。図７は本発明の防護柵を設置した状態を例示する概略正面図である。 FIG. 1 is a front view of an essential part showing an embodiment of a protective fence of the present invention. FIG. 7 is a schematic front view illustrating a state where the guard fence of the present invention is installed.
図７に示すように、防護柵１は、適宜間隔をおいて地表Ｅに立設された支柱１０と、隣り合う支柱１０間に掛け渡して設けられた上下一対の胴縁２０と、上下の胴縁２０を連結する縦格子パネル３０と、を有している。 As shown in FIG. 7, the protective fence 1 is composed of a column 10 erected on the surface E with an appropriate interval, a pair of upper and lower trunk edges 20 provided between adjacent columns 10, and upper and lower And a vertical lattice panel 30 for connecting the trunk edges 20.
図１に示すように、胴縁２０は、金属板を曲げ加工して一定幅のスリット２１ｓを有する円筒体を形成するとともに、その金属板の曲げ方向両端部を内側に屈曲させて縦格子パネル支持部２２を形成してなる。縦格子パネル支持部２２は、スリット２１ｓの幅方向中心に関して対称になるように、スリット２１ｓの両縁から胴縁２０の内側に向かって逆くさび状に拡開している。縦格子パネル支持部２２の角度（鉛直軸に対する角度）θ１（図４参照）は、３０〜５０度の範囲、より好ましくは４０〜５０度の範囲から選ばれる。胴縁２０の両端近傍の上下方向中央部両側には、支柱１０への取り付け時に使用されるボルト挿通孔２３（図４参照）が形成されている。 As shown in FIG. 1, the body edge 20 is formed by bending a metal plate to form a cylindrical body having slits 21 s of a certain width, and bending the both ends of the metal plate in the bending direction inwardly forms a vertical lattice panel. A support portion 22 is formed. The vertical lattice panel support portion 22 is expanded in a reverse wedge shape from both edges of the slit 21s toward the inside of the trunk edge 20 so as to be symmetric with respect to the center in the width direction of the slit 21s. The angle (angle with respect to the vertical axis) θ1 (see FIG. 4) of the vertical lattice panel support 22 is selected from a range of 30 to 50 degrees, more preferably a range of 40 to 50 degrees. Bolt insertion holes 23 (see FIG. 4) used when attaching to the column 10 are formed on both sides of the central portion in the vertical direction near both ends of the trunk edge 20.
縦格子パネル３０は、胴縁２０の長手方向（図１の紙面に対し垂直方向）に並設される複数本の縦格子３１と、隣り合う縦格子３１同士の間隔を等間隔に保持する間隔保持材３２とを有している。 The vertical lattice panel 30 has a plurality of vertical lattices 31 arranged side by side in the longitudinal direction of the trunk edge 20 (perpendicular to the paper surface of FIG. 1), and an interval that keeps an interval between adjacent vertical lattices 31 at equal intervals. Holding member 32.
縦格子３１は、金属製の円筒体である。縦格子３１には、押し潰し加工により扁平部（間隔保持材連結部）３１ａが形成され、各扁平部３１ａには、リベット挿通孔３１ｂが形成されている（図２参照）。 The vertical lattice 31 is a metal cylinder. In the vertical lattice 31, flat portions (interval holding member connecting portions) 31a are formed by crushing, and rivet insertion holes 31b are formed in each flat portion 31a (see FIG. 2).
間隔保持材３２は、細長い金属板を曲げ加工することにより、その長手方向に対し直交する断面形状がレ字形をなすように成型された部材であり（図３参照）、上下に延びる縦格子保持部３２ａと、縦格子保持部３２ａの一方の長縁部から折り曲げられて斜めに延びる胴縁係合部３２ｂとを有している。縦格子保持部３２ａに対する胴縁係合部３２ｂの角度（鉛直軸に対する角度）θ２（図３（Ａ）参照）は、３０〜５０度の範囲、より好ましくは４０〜５０度の範囲から選ばれる。 The spacing member 32 is a member formed by bending a long and narrow metal plate so that a cross-sectional shape orthogonal to the longitudinal direction forms a letter shape (see FIG. 3). Part 32a and body edge engaging part 32b which is bent from one long edge part of vertical lattice holding part 32a and extends diagonally. The angle (angle with respect to the vertical axis) θ2 (see FIG. 3A) of the trunk edge engaging portion 32b with respect to the vertical lattice holding portion 32a is selected from the range of 30 to 50 degrees, more preferably from the range of 40 to 50 degrees. .
間隔保持材３２は、互いの縦格子保持部３２ａを背中合わせにした姿勢で、縦格子３１の扁平部３１ａを挟んで、縦格子パネル３０の上端と下端にそれぞれ２本ずつ、合計４本設けられている。これら４本の間隔保持材３２は、いずれも同形同寸であり、全長寸法は胴縁２０の全長よりも若干短めに選定されている。上下の間隔保持材３２の胴縁係合部３２ｂは互いに対向している。同形同寸の間隔保持材３２が、互いの縦格子保持部３２ａを背中合わせにした姿勢で、縦格子３１の扁平部３１ａを挟んで配置されることにより、各間隔保持材３２の対における２つの胴縁係合部３２ｂが縦格子３１の扁平部３１ａの厚さ方向中心に関して対称に配置される。 A total of four spacing members 32 are provided at the upper end and the lower end of the vertical lattice panel 30 with the flat portion 31a of the vertical lattice 31 sandwiched between the vertical lattice holding portions 32a back to back. ing. These four spacing members 32 have the same shape and the same size, and the overall length is selected to be slightly shorter than the overall length of the trunk edge 20. The trunk edge engaging portions 32b of the upper and lower spacing members 32 face each other. The spacing members 32 of the same shape and the same size are arranged with the vertical lattice holding portions 32a back to back with the flat portions 31a of the vertical lattices 31 sandwiched therebetween, so that 2 in each pair of the spacing retaining materials 32. Two trunk edge engaging portions 32 b are arranged symmetrically with respect to the center in the thickness direction of the flat portion 31 a of the vertical lattice 31.
間隔保持材３２の縦格子保持部３２ａには、その長手方向に等間隔に複数のリベット挿通孔３２ｃが形成されている。リベット挿通孔３２ｃは、間隔保持材３２の両端から離れた位置に形成されている。間隔保持材３２と縦格子３１は、互いのリベット挿通孔３２ｃ、３１ｂが連通するように重ね合わせた状態で、両リベット挿通孔３２ｃ、３１ｂにリベット３３を挿通してかしめることにより互いに回動可能に連結されている。縦格子パネル３０は、その間隔保持材３２と縦格子３１とがリベット３３を軸として互いに回動可能であることにより、いわゆる平行リンク機構を構成している。 A plurality of rivet insertion holes 32 c are formed at equal intervals in the longitudinal direction of the vertical lattice holding portion 32 a of the interval holding member 32. The rivet insertion hole 32 c is formed at a position away from both ends of the spacing member 32. The spacing member 32 and the vertical lattice 31 rotate with each other by caulking the rivet 33 through the rivet insertion holes 32c and 31b in a state where the rivet insertion holes 32c and 31b are overlapped with each other. Connected as possible. The vertical lattice panel 30 constitutes a so-called parallel link mechanism by the interval holding member 32 and the vertical lattice 31 being rotatable with respect to the rivet 33 as an axis.
この防護柵１は、縦格子パネル３０の上下に胴縁２０を取り付けた後、上下の胴縁２０のそれぞれの両端部を支柱１０に固定することにより、歩道脇などに設置される。 The protective fence 1 is installed on the side of a sidewalk by attaching both ends of the upper and lower trunk edges 20 to the column 10 after attaching the trunk edges 20 to the upper and lower sides of the vertical lattice panel 30.
胴縁２０の縦格子パネル３０への取り付けは、縦格子パネル３０に対して胴縁２０をスライドさせて、胴縁２０内に間隔保持材３２を挿入することによりなされる（図５、図６参照）。この時点で、間隔保持材３２の胴縁係合部３２ｂが胴縁２０の縦格子パネル支持部２２にくさび状に係合する。 The trunk edge 20 is attached to the vertical lattice panel 30 by sliding the trunk edge 20 with respect to the vertical lattice panel 30 and inserting a spacing member 32 into the trunk edge 20 (FIGS. 5 and 6). reference). At this point, the trunk edge engaging portion 32 b of the spacing member 32 engages with the vertical lattice panel support portion 22 of the trunk edge 20 in a wedge shape.
胴縁２０の支柱１０への取り付けは、図８に例示するように、胴縁２０の端部を取付金具４０を介して支柱１０に連結することによりなされる。取付金具４０は、支柱１０の外面に嵌合する円弧状の支柱取付部４１と、支柱取付部４１から前後に延びる胴縁連結部４２とを有し、２つ一組で支柱１０を抱き込むように配置される。胴縁連結部４２にはボルト挿通孔４２ａが形成されている。胴縁２０の端部を一組の取付金具４０の胴縁連結部４２の間に配置し、両者のボルト挿通孔４２ａ、２３にボルト４３を挿通し、ナット４４を取り付けて締着することにより、胴縁２０の端部が支柱１０に固定される。 The trunk edge 20 is attached to the column 10 by connecting the end of the trunk edge 20 to the column 10 via the mounting bracket 40 as illustrated in FIG. The mounting bracket 40 includes an arc-shaped column mounting portion 41 that fits to the outer surface of the column 10 and a trunk edge coupling portion 42 that extends forward and backward from the column mounting unit 41 and holds the column 10 in pairs. Are arranged as follows. A bolt insertion hole 42 a is formed in the trunk edge connecting portion 42. By disposing the end portion of the trunk edge 20 between the trunk edge connecting portions 42 of the pair of mounting brackets 40, inserting bolts 43 through the bolt insertion holes 42a and 23, and attaching and tightening nuts 44. The end of the trunk edge 20 is fixed to the column 10.
上記のように構成された防護柵１は、縦格子パネル３０の間隔保持材３２の胴縁係合部３２ｂが胴縁２０の縦格子パネル支持部２２にくさび状に係合するため、縦格子３１の扁平部３１ａの厚さによらず、同一種類の間隔保持材３２を使用して上下の胴縁２０間に縦格子３１を安定に保持可能である。すなわち、図９（Ａ）、（Ｂ）に例示するように、縦格子３１の扁平部３１ａの厚さＴ１、Ｔ２が異なる場合でも、逆くさび状に形成された縦格子パネル支持部２２とくさび状に形成された間隔保持材３２の胴縁係合部３２ｂとの互いの係合の度合いがくさび機能によって変化することによって当該厚さＴ１、Ｔ２の差分（Ｔ２−Ｔ１）を吸収し、胴縁２０と縦格子３１との間のガタ付きを防止できる。 The guard fence 1 configured as described above has a vertical lattice because the trunk edge engaging portion 32b of the spacing member 32 of the vertical lattice panel 30 engages with the vertical lattice panel support portion 22 of the trunk edge 20 in a wedge shape. The vertical lattice 31 can be stably held between the upper and lower body edges 20 by using the same type of spacing member 32 regardless of the thickness of the flat portion 31a of the 31. That is, as illustrated in FIGS. 9A and 9B, even when the thicknesses T1 and T2 of the flat portions 31a of the vertical lattice 31 are different, the vertical lattice panel support portion 22 and the wedge formed in a reverse wedge shape are used. The difference between the thicknesses T1 and T2 (T2−T1) is absorbed by the degree of mutual engagement of the spacing member 32 formed in the shape with the trunk edge engaging portion 32b by the wedge function, and the trunk The backlash between the edge 20 and the vertical lattice 31 can be prevented.
さらに、この防護柵１は、縦格子パネル支持部２２が胴縁２０のスリット２１ｓの幅方向中心に関して対称に形成され、間隔保持材３２の胴縁係合部３２ｂが縦格子３１の扁平部３１ａの厚さ方向中心に関して対称に形成されているため、胴縁係合部３２ｂと縦格子パネル支持部２２とがくさび状に係合することにより、何ら調整作業を要することなく、全ての縦格子３１がスリット２１ｓの幅方向中心に配置される。 Further, in this protective fence 1, the vertical lattice panel support portion 22 is formed symmetrically with respect to the center in the width direction of the slit 21 s of the trunk edge 20, and the trunk edge engaging portion 32 b of the spacing member 32 is a flat portion 31 a of the vertical lattice 31. Since the body edge engaging portion 32b and the vertical lattice panel support portion 22 are engaged in a wedge shape, all vertical lattices can be obtained without any adjustment work. 31 is arranged at the center of the slit 21s in the width direction.
また、間隔保持材３２の両端から離れた位置にリベット挿通孔３２ｃが形成されていることにより、間隔保持材３２の両端が縦格子３１よりも外側に位置している。この構造により、胴縁２０への間隔保持材３２の挿入作業時における縦格子３１の引っ掛かりをなくし、作業性を向上できる。 In addition, since the rivet insertion holes 32 c are formed at positions away from both ends of the spacing member 32, both ends of the spacing member 32 are located outside the vertical lattice 31. With this structure, the vertical lattice 31 is not caught when the spacing member 32 is inserted into the trunk edge 20, and workability can be improved.
本発明の構成は上記実施形態の構成に限定されるものではない。
たとえば、上記実施形態では、間隔保持材３２として、胴縁２０の全長寸法とほぼ同寸（若干短寸）のものが縦格子パネル３０の上端と下端にそれぞれ２本ずつ設けられているが、図１０に例示するように、各間隔保持材３４の全長寸法を胴縁２０の全長寸法よりも可成り小さくし、複数の間隔保持材３４を平面視千鳥状に配置することにより、全体として上記実施形態の間隔保持材３２の全長寸法とほぼ同寸にすることも可能である。また、図１１に例示するように、一方の側のみ上記実施形態の間隔保持材３２を配置し、もう一方の側には上記実施形態の間隔保持材３２よりも短寸の間隔保持材３５を間欠的に配置するようにしてもよい。図１０及び図１１に例示する構成によれば、上記実施形態の構成と比較して、縦格子パネル３０に使用する間隔保持材の総重量を軽減することができる。図１０及び図１１に例示する構成においても、胴縁２０の縦格子３１の並び方向から見たときに、間隔保持材の胴縁係合部が縦格子３１の扁平部３１ａの厚さ方向中心に関して対称に配置され、これが胴縁２０の縦格子パネル支持部２２にくさび状に係合するため、胴縁２０と間隔保持材との間のガタ付きを防止し、縦格子３１を安定に保持することができる。
The configuration of the present invention is not limited to the configuration of the above embodiment.
For example, in the above embodiment, two spacing members 32 are provided at the upper end and the lower end of the vertical lattice panel 30 respectively, approximately the same as the overall length of the trunk edge 20 (slightly shorter). As illustrated in FIG. 10, the overall length of each spacing member 34 is made considerably smaller than the overall length of the trunk edge 20, and the plurality of spacing members 34 are arranged in a zigzag shape in plan view, so that It is also possible to make it substantially the same as the overall length of the spacing member 32 of the embodiment. Further, as illustrated in FIG. 11, the spacing member 32 of the above embodiment is disposed only on one side, and the spacing member 35 shorter than the spacing member 32 of the above embodiment is disposed on the other side. You may make it arrange | position intermittently. According to the configuration illustrated in FIGS. 10 and 11, the total weight of the spacing members used for the vertical lattice panel 30 can be reduced as compared with the configuration of the above embodiment. 10 and 11 also, when viewed from the arrangement direction of the vertical grids 31 of the trunk edge 20, the trunk edge engaging part of the spacing member is the center in the thickness direction of the flat part 31a of the vertical grid 31. Are arranged symmetrically with respect to each other, and this engages with the vertical lattice panel support portion 22 of the trunk edge 20 in a wedge shape, thereby preventing rattling between the trunk edge 20 and the spacing member and stably holding the vertical lattice 31. can do.
また、縦格子パネル支持部２２の角度θ１及び胴縁係合部３２ｂの角度θ２は、両角度θ１、θ２の合計角度（θ１＋θ２）が９０度以下になる範囲で、一方の角度をより大きく選定し、他方の角度をより小さく選定することが可能である。これらの角度θ１、θ２を適切に選定することにより、縦格子パネル支持部２２と胴縁係合部３２ｂとの係合状態の安定性を確保しつつ、胴縁２０及び間隔保持材３２の耐荷重性を高めることができる。 Further, the angle θ1 of the vertical lattice panel support 22 and the angle θ2 of the trunk edge engaging portion 32b are selected to be larger in a range where the total angle (θ1 + θ2) of both the angles θ1 and θ2 is 90 degrees or less. However, the other angle can be selected smaller. By appropriately selecting these angles θ1 and θ2, the stability of the engagement state between the vertical lattice panel support portion 22 and the trunk edge engaging portion 32b is ensured, and the resistance of the trunk edge 20 and the spacing member 32 is improved. Loadability can be increased.
