Description

本発明は、手摺やフェンスなど、横材を被取付材に取り付けた構造を有する構造体に関する。 The present invention relates to a structure having a structure in which a cross member is attached to a material to be attached, such as a handrail or a fence.

手摺やフェンスにおいて中桟の端部を縦桟に連結したものなど、横材の端部を被取付材に連結した構造を有する構造体がある。従来、このような横材と被取付材の連結には、特許文献１に示すような連結金具を用いていた。より詳しくは、被取付材（フェンス支柱）の側面に連結金具の一片を取り付け、横材（ビーム材）の下面に連結金具の他片を取り付けて、横材を被取付材に連結していた。 Some structures have a structure in which the end of a cross member is connected to a material to be attached, such as a handrail or a fence in which the end of a center rail is connected to a vertical rail. Conventionally, a connecting metal fitting as shown in Patent Document 1 has been used to connect such a cross member and a material to be attached. More specifically, one piece of the connecting metal fitting was attached to the side surface of the material to be attached (fence support), and another piece of the connecting metal fitting was attached to the lower surface of the horizontal material (beam material) to connect the horizontal material to the material to be attached. ..

しかしながら、このような従来の連結構造では、被取付材の形状などによっては、横材の小口の一部が露出し、意匠性が悪くなっていた。また、露出した小口に触れて怪我をするおそれがあり、安全上も問題であった。 However, in such a conventional connecting structure, a part of the edge of the cross member is exposed depending on the shape of the material to be attached, and the design is deteriorated. In addition, there is a risk of injury by touching the exposed edge, which is also a safety problem.

本発明は、上記事情を鑑みたものであり、被取付材に連結する横材を有するものであって、横材の小口が露出しない構造体を提供することを目的とする。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a structure having a cross member connected to a material to be attached and the edge of the cross member is not exposed.

本発明は、横材と、小口部材と、横材固定具を備え、小口部材は、裏板部と、キャップ部を一体に形成してあり、裏板部が横材の中空部に挿入してあり、キャップ部が横材の小口を覆っており、横材固定具は、小口部材のキャップ部と対向する位置で被取付材に取り付けてあり、横材を横材固定具に当接させ、横材固定具側から裏板部にネジ止めして、横材を被取付材に固定するとともに、小口部材を横材に固定してあることを特徴とする。
The present invention includes a cross member, an edge member, and a cross member fixture. The edge member has a back plate portion and a cap portion integrally formed, and the back plate portion is inserted into a hollow portion of the cross member. The cap portion covers the edge of the cross member, and the cross member fixture is attached to the attached material at a position facing the cap portion of the edge member, and the cross member is brought into contact with the cross member fixture. It is characterized in that the cross member is fixed to the attached material by screwing from the cross member fixture side to the back plate portion, and the edge member is fixed to the cross member.

本発明によれば、小口部材のキャップ部が横材の小口を覆うので、小口が露出せず、意匠性が良好で、安全である。そして、横材を横材固定具に固定するネジを、小口部材を横材に固定するネジと兼用しているので、部品点数が少なく、施工が容易である。 According to the present invention, since the cap portion of the edge member covers the edge of the cross member, the edge is not exposed, the design is good, and it is safe. Further, since the screw for fixing the cross member to the cross member fixture is also used as the screw for fixing the edge member to the cross member, the number of parts is small and the construction is easy.

以下、本発明の実施の形態を図面に基づいて説明する。この構造体は、種々の用途に用いられるものであるが、ここでは階段部に設置する手摺として用いられる場合を示す。図４に示すように、この手摺は、支柱４ａ，４ｂ，４ｃ，４ｄ，４ｅと、笠木５と、中桟（横材）１を備える。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. This structure is used for various purposes, but here, a case where it is used as a handrail to be installed on a staircase is shown. As shown in FIG. 4, this handrail includes columns 4a, 4b, 4c, 4d, 4e, a cap tree 5, and a center rail (cross member) 1.

支柱は、階段の各段に１本又は複数本立設してあり、階段の下側に立設したものから順に４ａ〜４ｅとなっていて、上端の高さ順に並んでいる。すなわち、支柱４ａと支柱４ｂは同じ段に立設してあるが、支柱４ｂの方が長いので上端の高さが高い。また、支柱４ｂと支柱４ｃは同じ長さであるが、支柱４ｃの方が上の段に立設してあるので上端の高さが高い。同じく、支柱４ｃと支柱４ｄは同じ長さであるが、支柱４ｄの方が上の段に立設してあるので上端の高さが高い。そして、支柱４ｅは支柱４ｄよりも上の段に立設してあるが、支柱４ｅの方が短く、支柱４ｄと支柱４ｅの上端の高さは同じである。なお、隣接する支柱間（支柱４ｄと支柱４ｅを除く）の上端の高さの差は全て等しく、階段の１段の高さと同じである。 One or more columns are erected on each step of the stairs, and the columns are 4a to 4e in order from the one erected on the lower side of the stairs, and are arranged in the order of the height of the upper end. That is, although the columns 4a and 4b are erected on the same stage, the height of the upper end is higher because the columns 4b are longer. Further, although the columns 4b and the columns 4c have the same length, the height of the upper end is higher because the columns 4c are erected on the upper stage. Similarly, the support columns 4c and the support columns 4d have the same length, but the height of the upper end is higher because the support columns 4d are erected on the upper stage. The support column 4e is erected on a step higher than the support column 4d, but the support column 4e is shorter, and the heights of the upper ends of the support column 4d and the support column 4e are the same. The difference in height between the adjacent columns (excluding the columns 4d and 4e) is the same as the height of one step of the stairs.

笠木５は、手摺の上端部に取り付けた水平方向に延びる部材である。上記のとおり、支柱は上端の高さ順に並んでおり、隣接する支柱の上端の高さが異なるので、笠木５は、隣接する支柱間において、一端を低い方の支柱の上端に取り付けてあり、他端を高い方の支柱の側面に取り付けてある。ここで、一端側は階段の降り側となり、他端側は階段の昇り側となる。すなわち、支柱４ａと支柱４ｂにおいて、笠木５は降り側の支柱４ａの上端と、昇り側の支柱４ｂの側面に取り付けてある。同様に、支柱４ｂと支柱４ｃにおいて、笠木５は降り側の支柱４ｂの上端と、昇り側の支柱４ｃの側面に取り付けてあり、支柱４ｃと支柱４ｄにおいて、笠木５は降り側の支柱４ｃの上端と、昇り側の支柱４ｄの側面に取り付けてある。そして、支柱４ｄと支柱４ｅにおいて、笠木５は両支柱４ｄ，４ｅの上端に取り付けてある。 The Kasagi 5 is a member attached to the upper end of the handrail and extending in the horizontal direction. As described above, the columns are arranged in the order of the height of the upper end, and the heights of the upper ends of the adjacent columns are different. Therefore, the Kasagi 5 has one end attached to the upper end of the lower column between the adjacent columns. The other end is attached to the side of the higher strut. Here, one end side is the descending side of the stairs, and the other end side is the ascending side of the stairs. That is, in the support columns 4a and 4b, the cap tree 5 is attached to the upper end of the support column 4a on the descending side and the side surface of the support column 4b on the ascending side. Similarly, in the columns 4b and 4c, the cap tree 5 is attached to the upper end of the descending column 4b and the side surface of the ascending column 4c, and in the columns 4c and 4d, the cap tree 5 is attached to the descending column 4c. It is attached to the upper end and the side surface of the ascending support column 4d. Then, in the columns 4d and 4e, the cap tree 5 is attached to the upper ends of both columns 4d and 4e.

中桟１は、手摺の上下方向中間部に取り付けた水平方向に延びる部材である。隣接する支柱間において、笠木５の下側に、１本又は複数本の中桟１を取り付けてあり、より詳しくは、支柱４ａと支柱４ｂの間に１本、支柱４ｂと支柱４ｃの間及び支柱４ｃと支柱４ｄの間に２本、支柱４ｄと支柱４ｅの間に３本取り付けてある。そして、笠木５と中桟１の間隔及び中桟１同士の間隔は、隣接する支柱間の上端の高さの差（階段の１段の高さ）と同じである。よって、支柱を挟んで隣接する笠木５と中桟１又は中桟１同士が、同じ高さ位置となっている The center rail 1 is a member that extends in the horizontal direction and is attached to the vertical intermediate portion of the handrail. Between the adjacent columns, one or more middle rails 1 are attached to the lower side of the cap tree 5, and more specifically, one between the columns 4a and 4b, between the columns 4b and 4c, and between the columns 4b and 4c. Two are attached between the support 4c and the support 4d, and three are attached between the support 4d and the support 4e. The distance between the cap tree 5 and the middle rail 1 and the distance between the middle rails 1 are the same as the difference in the height of the upper ends between the adjacent columns (the height of one step of the stairs). Therefore, the Kasagi 5 adjacent to each other across the support and the middle rail 1 or the middle rail 1 are at the same height position.

次に、各部材同士の連結構造について詳述する。まず、図５に基づき、笠木５と支柱の連結構造について説明する。なお、図５は支柱４ａと支柱４ｂについて示したものであるが、他の支柱においても同じである。笠木５は、断面略矩形の形材であって、中空部５１を有し、下面の見込方向中央部には、長手方向に沿って延びる断面略コ字形の溝部５２を形成してあり、さらに溝部５２の底面には、長手方向に沿って延びる断面略Ｃ字形の係止部５３を形成してある。そして、笠木５の階段の降り側（支柱４ａ側）の端部には、端部部品６を取り付けてある。端部部品６は、略矩形平板形状のカバー部６１と、カバー部６１の笠木５側から突出する挿入片６２からなる。カバー部６１の笠木５側の面は掘り込んであって、笠木５の端部が丁度嵌まり込む形状となっており、カバー部６１に笠木５の端部が嵌まり込んだ状態で、端部部品６の挿入片６２が笠木５の中空部５１に挿入される。この挿入片６２に対して、笠木５の下面側（係止部５３の底面）からネジ止めして、笠木５に端部部品６を固定してある。そして、階段の降り側（支柱４ａ側）においては、支柱４ａの上端に、端面を覆う矩形平板状の上端板８をネジ止めして取り付けてあり、さらに上端板８の上面に、矩形平板状の連結板９をネジ止めして取り付けてある。連結板９は、笠木５の溝部５２に丁度納まる幅と厚さを有し、取り付けた支柱４ａから隣接する支柱４ｂ側に向けて突出している。この連結板９を溝部５２に納めるようにして、笠木５の階段の降り側の端部が支柱４ａに載置してあり、連結板９の突出部分の下側から、笠木５の係止部５３内に納めた裏板１０に対してネジ止めすることで、笠木５と階段の降り側の支柱４ａを連結してある。また、階段の昇り側（支柱４ｂ側）においては、支柱４ｂの側面に、突当具７を取り付けてある。突当具７は、端部部品６と略同じ形状で、カバー部７１と挿入片７２を有しており、カバー部７１を支柱４ｂにネジ止めしてある。そして、カバー部７１に笠木５の端部が嵌まり込んだ状態で、突当具７の挿入片７２が笠木５の中空部５１に挿入されており、この挿入片７２に対して、笠木５の下面側（係止部５３の底面）からネジ止めして、笠木５に突当具７を固定することで、笠木５と階段の昇り側の支柱４ｂを連結してある。なお、突当具７の高さ位置は、階段の降り側の支柱４ａの高さに合わせてあるので、笠木５は水平に設けられる。 Next, the connection structure between the members will be described in detail. First, the connection structure between the Kasagi 5 and the support column will be described with reference to FIG. Note that FIG. 5 shows the columns 4a and 4b, but the same applies to the other columns. The Kasagi 5 is a profile having a substantially rectangular cross section, has a hollow portion 51, and has a groove portion 52 having a substantially U-shaped cross section extending along the longitudinal direction at the central portion in the prospective direction of the lower surface thereof. A locking portion 53 having a substantially C-shaped cross section extending along the longitudinal direction is formed on the bottom surface of the groove portion 52. An end component 6 is attached to the end of the Kasagi 5 on the descending side (post 4a side) of the stairs. The end component 6 includes a cover portion 61 having a substantially rectangular flat plate shape, and an insertion piece 62 projecting from the cap tree 5 side of the cover portion 61. The surface of the cover portion 61 on the Kasagi 5 side is dug into a shape in which the end portion of the Kasagi 5 is just fitted, and the end portion of the Kasagi 5 is fitted into the cover portion 61 at the end. The insertion piece 62 of the part component 6 is inserted into the hollow portion 51 of the cover tree 5. The end component 6 is fixed to the cap tree 5 by screwing the insertion piece 62 from the lower surface side of the cap tree 5 (the bottom surface of the locking portion 53). Then, on the descending side of the stairs (support 4a side), a rectangular flat plate-shaped upper end plate 8 covering the end face is screwed and attached to the upper end of the support column 4a, and further, a rectangular flat plate shape is attached to the upper surface of the upper end plate 8. The connecting plate 9 of the above is screwed and attached. The connecting plate 9 has a width and a thickness that just fits in the groove 52 of the cap tree 5, and protrudes from the attached support column 4a toward the adjacent support column 4b side. The connecting plate 9 is housed in the groove 52, and the lower end of the stairs of the Kasagi 5 is placed on the support column 4a, and the locking portion of the Kasagi 5 is placed from the lower side of the protruding portion of the connecting plate 9. The Kasagi 5 and the support column 4a on the down side of the stairs are connected by screwing to the back plate 10 housed in the 53. Further, on the ascending side of the stairs (on the side of the support column 4b), the abutting tool 7 is attached to the side surface of the support column 4b. The abutting tool 7 has substantially the same shape as the end component 6, has a cover portion 71 and an insertion piece 72, and the cover portion 71 is screwed to the support column 4b. Then, with the end portion of the cap tree 5 fitted in the cover portion 71, the insertion piece 72 of the abutting tool 7 is inserted into the hollow portion 51 of the cap tree 5, and the cap tree 5 is inserted into the insertion piece 72. The cap tree 5 and the support column 4b on the ascending side of the stairs are connected by fixing the abutting tool 7 to the cap tree 5 by screwing from the lower surface side (bottom surface of the locking portion 53). Since the height position of the abutment tool 7 is adjusted to the height of the support column 4a on the descending side of the stairs, the Kasagi 5 is provided horizontally.

続いて、図１〜図３に基づき、中桟（横材）１と支柱（被取付材）の連結構造について説明する。なお、図１は支柱４ｂについて示したものであるが、他の支柱においても同じである。中桟１は、断面略矩形の形材であって、中空部１１を有し、下面の見込方向中央部には、長手方向に沿って延びる断面略コ字形の溝部１２を形成してある。そして、中桟１の端部には、小口部材２を取り付けてある。小口部材２は、１枚の金属平板を曲げて形成したものであり、中桟１の中空部１１に挿入してある裏板部２１と、中桟１の小口を覆うキャップ部２２を備える。キャップ部２２は、中桟１の断面よりわずかに大きな矩形平板状のものであって、下側から２本の切り込みを入れて見込方向中央部を中桟１側に折り曲げてあり、折り曲げた部分の下側は切欠部２３となっている。折り曲げた部分は、キャップ部２２から中桟１側へ水平向きに延びる延出面２４と、延出面２４の先端から下向きに延びる垂直面２５と、垂直面２５の下端から中桟１側へ水平向きに延びる裏板部２１を形成している。中桟１の中空部１１に挿入された裏板部２１は、中桟１の下面（溝部１２の底面）に上側から当接している。また、支柱４ｂの側面には、横材固定具３を取り付けてある。横材固定具３は、Ｌ字金具からなり、水平向きの載置部３１と、垂直向きの取付部３２を備え、見込幅は中桟１の溝部１２に丁度納まる幅である。取付部３２を支柱４ｂの側面にネジ止めして固定してあり、載置部３１が支柱４ｂから水平向きに突出している。そして、横材固定具３の載置部３１を溝部１２に納めるようにして、中桟１の端部を横材固定具３の載置部３１に載置してあり、載置部３１の下側から、溝部１２の底面を貫通して小口部材２の裏板部２１にネジ止めすることで、中桟１を支柱４ｂに固定するとともに、小口部材２を中桟１に固定してある。この際、横材固定具３の取付部３２は、小口部材２のキャップ部２２に形成した切欠部２３に納まっており、横材固定具３と小口部材２が干渉することはない。 Subsequently, the connecting structure of the center rail (horizontal member) 1 and the support column (attached material) will be described with reference to FIGS. 1 to 3. Note that FIG. 1 shows the support column 4b, but the same applies to the other columns. The middle rail 1 is a profile having a substantially rectangular cross section, has a hollow portion 11, and has a groove portion 12 having a substantially U-shaped cross section extending along the longitudinal direction at the central portion in the prospective direction on the lower surface. A fore edge member 2 is attached to the end of the center rail 1. The edge member 2 is formed by bending one metal flat plate, and includes a back plate portion 21 inserted into the hollow portion 11 of the center rail 1 and a cap portion 22 that covers the edge of the center rail 1. The cap portion 22 has a rectangular flat plate shape slightly larger than the cross section of the center rail 1, and has two cuts from the lower side and the central portion in the prospective direction is bent toward the center rail 1, and the bent portion. The lower side is a notch 23. The bent portion includes an extending surface 24 extending horizontally from the cap portion 22 to the center rail 1 side, a vertical surface 25 extending downward from the tip of the extending surface 24, and horizontally extending from the lower end of the vertical surface 25 to the center rail 1 side. A back plate portion 21 extending to is formed. The back plate portion 21 inserted into the hollow portion 11 of the middle rail 1 is in contact with the lower surface of the middle rail 1 (the bottom surface of the groove portion 12) from above. Further, a cross member fixture 3 is attached to the side surface of the support column 4b. The cross member fixture 3 is made of an L-shaped metal fitting, includes a horizontally oriented mounting portion 31 and a vertically oriented mounting portion 32, and the expected width is a width that fits exactly in the groove portion 12 of the center rail 1. The mounting portion 32 is fixed to the side surface of the support column 4b by screwing, and the mounting portion 31 projects horizontally from the support column 4b. Then, the mounting portion 31 of the cross member fixing tool 3 is housed in the groove portion 12, and the end portion of the center rail 1 is mounted on the mounting portion 31 of the cross member fixing tool 3, and the mounting portion 31 By penetrating the bottom surface of the groove portion 12 and screwing it to the back plate portion 21 of the edge member 2 from the lower side, the center rail 1 is fixed to the support column 4b, and the edge member 2 is fixed to the center rail 1. .. At this time, the mounting portion 32 of the cross member fixing tool 3 is housed in the notch portion 23 formed in the cap portion 22 of the edge member 2, so that the cross member fixing tool 3 and the edge member 2 do not interfere with each other.

次に、図６に基づき、このように構成した構造体の製造方法（施工手順）について説明する。まず、階段部に、支柱４ａ〜４ｅを上端の高さ順に並べて立設する（図６（ａ））。支柱４ａから支柱４ｄにかけては、上端の高さが階段の１段の高さ分ずつ高くなっており、支柱４ｄと支柱４ｅの上端の高さは同じである。次に、隣接する支柱間において、笠木５の一端を低い方の支柱の上端に取り付けるとともに、他端を高い方の支柱の側面に取り付ける（図６（ｂ））。ここでは、階段の降り側の支柱４ａ，４ｂ間から順に取り付けるものとし、まず、笠木５の階段の降り側（支柱４ａ側）の端部から係止部５３に裏板１０を挿入し、さらに端部に端部部品６を取り付け、下側からネジ止めして固定する。また、支柱４ａの上端の上端板８の上面に、連結板９をネジ止めして固定する。さらに、階段の昇り側の支柱４ｂの、階段の降り側の側面に、突当具７をネジ止めして固定する。この際、突当具７の高さ位置は、階段の降り側の支柱４ａの高さに合わせる。そして、階段の降り側において、連結板９を溝部５２に納めるようにして、笠木５の端部を支柱４ａに載置するとともに、階段の昇り側において、突当具７の挿入片７２を笠木５の中空部５１に挿入し、さらに連結板９の下側から笠木５の係止部５３内に納めた裏板１０に対してネジ止めするとともに、笠木５の下側から、中空部５１内に挿入した突当具７の挿入片７２にネジ止めする。次に、同様にして、他の支柱間に笠木５を取り付ける（図６（ｃ））。ただし、支柱４ｄと支柱４ｅの間においては、両端とも支柱４ｄ，４ｅの上端に取り付ける。次に、隣接する支柱間の笠木５の下側に中桟１を後付けする（図６（ｄ））。ここでは、階段の降り側の支柱４ａ，４ｂ間から順に取り付けるものとし、まず、両支柱４ａ，４ｂの対向する側面に、横材固定具３の取付部３２をネジ止めして固定する。この際、横材固定具３の高さ位置は、笠木５から階段の１段分の高さだけ離れた位置とする。次に、中桟１の両端に、それぞれ中空部１１に裏板部２１を挿入するようにして、小口部材２を取り付ける。そして、横材固定具３の載置部３１を溝部１２に納めるようにして、中桟１の両端部をそれぞれ横材固定具３の載置部３１に載置し、載置部３１の下側から、溝部１２の底面を貫通して小口部材２の裏板部２１にネジ止めする。次に、同様にして、他の支柱間にも中桟１を取り付け、構造体が完成する。 Next, a manufacturing method (construction procedure) of the structure configured in this way will be described with reference to FIG. First, columns 4a to 4e are erected on the stairs in order of height of the upper end (FIG. 6 (a)). From the support column 4a to the support column 4d, the height of the upper end is increased by the height of one step of the stairs, and the heights of the upper ends of the support column 4d and the support column 4e are the same. Next, between adjacent columns, one end of the cap tree 5 is attached to the upper end of the lower column, and the other end is attached to the side surface of the higher column (FIG. 6 (b)). Here, it is assumed that the back plate 10 is attached in order from between the columns 4a and 4b on the descending side of the stairs, first, the back plate 10 is inserted into the locking portion 53 from the end of the Kasagi 5 on the descending side of the stairs (post 4a side), and further. The end component 6 is attached to the end and fixed by screwing from the lower side. Further, the connecting plate 9 is screwed and fixed to the upper surface of the upper end plate 8 at the upper end of the support column 4a. Further, the abutting tool 7 is screwed and fixed to the side surface of the support column 4b on the ascending side of the stairs on the descending side of the stairs. At this time, the height position of the abutting tool 7 is adjusted to the height of the support column 4a on the descending side of the stairs. Then, on the descending side of the stairs, the connecting plate 9 is housed in the groove 52, the end portion of the cap tree 5 is placed on the support column 4a, and on the ascending side of the stairs, the insertion piece 72 of the abutting tool 7 is placed in the cap tree. It is inserted into the hollow portion 51 of the cap tree 5, and further screwed from the lower side of the connecting plate 9 to the back plate 10 housed in the locking portion 53 of the cap tree 5, and from the lower side of the cap tree 5 into the hollow portion 51. It is screwed to the insertion piece 72 of the abutting tool 7 inserted in. Next, in the same manner, the Kasagi 5 is attached between the other columns (FIG. 6 (c)). However, between the columns 4d and the columns 4e, both ends are attached to the upper ends of the columns 4d and 4e. Next, the center rail 1 is retrofitted to the lower side of the cap tree 5 between the adjacent columns (FIG. 6 (d)). Here, it is assumed that they are attached in order from between the columns 4a and 4b on the descending side of the stairs, and first, the attachment portion 32 of the cross member fixture 3 is screwed and fixed to the opposite side surfaces of both columns 4a and 4b. At this time, the height position of the cross member fixture 3 is set to a position separated from the Kasagi 5 by the height of one step of the stairs. Next, the edge member 2 is attached to both ends of the center rail 1 by inserting the back plate portion 21 into the hollow portion 11, respectively. Then, the mounting portion 31 of the cross member fixing tool 3 is housed in the groove portion 12, and both ends of the center rail 1 are mounted on the mounting portion 31 of the cross member fixing tool 3, respectively, and below the mounting portion 31. From the side, it penetrates the bottom surface of the groove portion 12 and is screwed to the back plate portion 21 of the edge member 2. Next, in the same manner, the center rail 1 is attached between the other columns to complete the structure.

このように構成した構造体によれば、小口部材２のキャップ部２２が中桟１の小口を覆うので、小口が露出せず、意匠性が良好で、安全である。そして、中桟１を横材固定具３に固定するネジを、小口部材２を中桟１に固定するネジと兼用しているので、部品点数が少なく、施工が容易である。また、中桟１を支柱に連結する際、中桟１の端部を横材固定具３の載置部３１に載置した状態でネジ止め作業を行うことができるので、作業性がよい。 According to the structure configured in this way, since the cap portion 22 of the edge member 2 covers the edge of the center rail 1, the edge is not exposed, the design is good, and it is safe. Since the screw for fixing the center rail 1 to the cross member fixture 3 is also used as the screw for fixing the edge member 2 to the center rail 1, the number of parts is small and the construction is easy. Further, when the center rail 1 is connected to the support column, the screw fastening work can be performed with the end portion of the center rail 1 mounted on the mounting portion 31 of the cross member fixing tool 3, so that the workability is good.

また、手摺として用いられる場合のこの構造体は、階段の傾斜角度によらず、笠木５を水平に設けることができ、笠木５に手を掛けて階段を昇る際、垂直下向きにかかる体重を水平な笠木５で受けるので、安定して身体を支えることができる。 Further, in this structure when used as a handrail, the cap tree 5 can be provided horizontally regardless of the inclination angle of the stairs, and when the cap tree 5 is touched and the stairs are climbed, the weight applied vertically downward is horizontally applied. Since it is received at Nagasagi 5, it can support the body in a stable manner.

さらに、手摺として用いられる場合のこの構造体の製造方法によれば、階段の傾斜角度によらず、笠木５を水平に設けることができ、笠木５に手を掛けて階段を昇る際、垂直下向きにかかる体重を水平な笠木５で受けるので、安定して身体を支えることができる手摺を製造できる。また、支柱４ａ〜４ｅと笠木５を組んでから、適宜支柱間に中桟１を後付けして、意匠を自在に変えることができる。 Further, according to the method of manufacturing this structure when used as a handrail, the cap tree 5 can be provided horizontally regardless of the inclination angle of the stairs, and when the cap tree 5 is touched and climbs the stairs, it faces vertically downward. Since the horizontal Kasagi 5 receives the weight applied to the body, it is possible to manufacture a handrail that can stably support the body. Further, after the columns 4a to 4e and the Kasagi 5 are assembled, the center rail 1 can be retrofitted between the columns as appropriate to freely change the design.

本発明は、上記の実施形態に限定されない。たとえば、中桟以外の水平向きの部材（横材）を、小口部材と横材固定具により被取付材に取り付けるものであってもよい。また、横材固定具は、下側以外の方向から横材に当接するものであってもよく、その場合も、横材固定具側から、小口部材の裏板部にネジ止めして固定する。さらに、この構造体は、手摺以外にも、フェンスなど種々の用途に用いることができる。 The present invention is not limited to the above embodiments. For example, a horizontally oriented member (horizontal member) other than the center rail may be attached to the attached material by the edge member and the horizontal member fixing tool. Further, the cross member fixing tool may be one that comes into contact with the cross member from a direction other than the lower side, and even in that case, the cross member fixing tool is fixed by screwing to the back plate portion of the edge member from the cross member fixing tool side. .. Further, this structure can be used for various purposes such as a fence as well as a handrail.
