Description

本発明は、例えば、屋内の吹き抜けを形成する二階の廊下に沿って取り付ける手摺や、階段の手摺における支柱の取付構造に関する。 The present invention relates to, for example, a handrail attached along a second-floor corridor that forms an indoor atrium and a structure for attaching a column in a staircase handrail.

一般に、多層建築においては、ベランダ、階段、または、吹き抜けなどを形成する廊下やデッキなどが高い位置に存在し、これらの領域の少なくとも一側部には、転落防止用の手摺が設けられている。係る手摺は、例えば、特許文献１に示すように、専用の手摺取付装置を用いて、床部に複数の支柱を垂直に取り付け、当該複数の支柱の間にパネルや柵体を取り付けることにより、施工されている。
一方、歩行用のスペースの確保や、デザイン性の見地から手摺用支柱を、廊下などの床面を支持する梁などの側面に取り付ける場合もある。 Generally, in a multi-layered building, a corridor or a deck that forms a veranda, a staircase, or an atrium is present at a high position, and at least one side of these areas is provided with a handrail for preventing falling. . Such a handrail, for example, as shown in Patent Document 1, by using a dedicated handrail attachment device, by vertically attaching a plurality of pillars to the floor, and attaching a panel or a fence between the plurality of pillars, It is being constructed.

実開平７−４０８７３号公報（第１〜７頁、図１〜４）Japanese Utility Model Publication No. 7-40873 (pages 1-7, FIGS. 1-4)

ところで、前述した何れの取付方法でも、手摺用支柱を取り付ける際に、何れかの支柱が垂直姿勢にならずに傾いたり、各支柱間の高さにバラ付きが生じる事態になることがある。この結果、各支柱間にパネルや柵体を取り付けたり、各支柱の上にまたがって笠木を固定することが困難となる。たとえ、上記取付や固定ができた場合でも、手摺全体のデザインを著しく損ねる、という問題があった。
しかも、前記特許文献１の手摺では、手摺用支柱を垂直に取り付けられる反面、手摺用支柱を取り付ける床面に対し、更に上階に手摺取付装置を設置する必要があるため、大かがりな工事となり、多数の労力と施工手数とを要する、という問題もあった。 By the way, in any of the attachment methods described above, when attaching the handrail support, any support may be tilted without being in a vertical posture, or the height between the supports may vary. As a result, it is difficult to attach a panel or a fence between the columns, or to fix the headboard over the columns. Even if the mounting and fixing can be performed, there is a problem that the design of the entire handrail is significantly impaired.
Moreover, in the handrail of the above-mentioned Patent Document 1, it is necessary to install a handrail mounting device on the upper floor with respect to the floor surface on which the handrail support column is attached while the handrail support post is attached vertically. There was also a problem of requiring a lot of labor and construction work.

本発明は、背景技術において説明した問題点を解決し、建物の梁や桁の側面に手摺の支柱を、垂直姿勢で且つ所定の高さにして、確実に取り付けられる手摺用支柱の取付構造を提供する、ことを課題とする。 The present invention solves the problems described in the background art, and has a handrail support mounting structure that can be securely attached to the side of a beam or girder of a building with a handrail support in a vertical posture and a predetermined height. The issue is to provide.

Means for Solving the Problems and Effects of the Invention

本発明は、前記課題を解決するため、発明者らの鋭意研究の結果、梁などの側面に取り付けるべき支柱を固定するボルトの位置を、少なくとも水平方向において調整可能とする、ことに着想して成されたものである。
即ち、本発明の手摺用支柱の取付構造（請求項１）は、梁または桁の側面に固定され、係る梁または桁の側面に接する内側面に垂直な凹溝または凹部を有し、且つ係る凹溝または凹部の底面と外側面との間を貫通する上下複数の横長の長孔を有するベースプレートと、係るベースプレートの凹溝または凹部に嵌装され、上記上下複数の横長の長孔と連通する上下複数の雌ネジ孔を有するナット板と、上記ベースプレートの外側面に接触し、且つ上下複数の貫通孔を有する支柱と、係る支柱の各貫通孔およびベースプレートの各長孔を貫通し且つ上記ナット板の各雌ネジ孔に螺合する複数の固定用ボルトと、を含む、ことを特徴とする。 In order to solve the above-mentioned problems, the present invention has been conceived as a result of the inventors' diligent research, which makes it possible to adjust the position of a bolt for fixing a column to be attached to a side surface such as a beam at least in the horizontal direction. It was made.
That is, the handrail post mounting structure according to the present invention (Claim 1) is fixed to a side surface of a beam or a girder, has a ditch or a recess perpendicular to an inner side surface in contact with the side surface of the beam or girder, and A base plate having a plurality of upper and lower horizontal elongated holes penetrating between the bottom surface and the outer surface of the concave groove or the concave portion, and is fitted into the concave groove or the concave portion of the base plate and communicates with the upper and lower horizontal elongated holes. A nut plate having a plurality of upper and lower female screw holes, a support column that contacts the outer surface of the base plate and has a plurality of upper and lower through holes, and the nuts that pass through the through holes of the support column and the long holes of the base plate. A plurality of fixing bolts screwed into the female screw holes of the plate.

これによれば、例えば、ベースプレートを梁の側面における所定の位置で、垂直線に対し左右方向の何れかに極く僅かの傾きを伴って固定した場合でも、係るベースプレートにおける上下複数の横長の長孔を活用し、これらの長孔を貫通する固定ボルトの位置を調整することで、上記傾きを矯正し且つ隣接する支柱の高さと同じ高さに揃えて、支柱を取り付けることができる。従って、複数の支柱間に柵体やパネルを容易に取り付けられ、且つ係る支柱の上端にまたがって笠木を、水平または所定の傾斜角度にして取り付けられると共に、手摺全体のデザインも確実に保証することが可能となる。 According to this, for example, even when the base plate is fixed at a predetermined position on the side surface of the beam with a slight inclination in any of the left and right directions with respect to the vertical line, the base plate has a plurality of horizontally long lengths. By utilizing the holes and adjusting the positions of the fixing bolts penetrating these long holes, the inclination can be corrected and the struts can be attached to the same height as the adjacent struts. Therefore, it is possible to easily attach a fence body or a panel between a plurality of support columns, and to install the headboard horizontally or at a predetermined inclination angle across the upper ends of the support columns, and to ensure the design of the entire handrail. Is possible.

尚、前記ベースプレートの内側面は、梁や桁の側面に接する側面であり、その外側面は内側面と反対側の側面である。また、前記凹溝を有するベースプレートは、例えば、アルミニウム合金の押出形材から形成しても良い。更に、前記凹部は、ベースプレートの内側面の中央部が凹んだ部分であり、係る凹部を有するベースプレートは、アルミニウム合金を含む各種の金属板における一方の表面を座ぐり加工することなどで形成しても良い。また、ベースプレートの前記凹溝は、断面長方形のほか、開口部が底よりも広い断面を呈する底広凹溝としても良い。この場合には、係る底広凹溝に嵌装するナット板の断面は、ほぼ台形やほぼ逆Ｔ字形とされる。更に、前記凹溝や凹部とナット板との幅方向の間には、係るナット板の傾動を許容する隙間を形成するが、係る隙間は、設計上の公差の範囲内におけるクリアランスとするか、これよりも大きな寸法であるほうが望ましい。
また、前記桁は、傾斜した階段用の桁を含み、階段の長手方向における一方の側面に沿った桁の他、階段の両側面に沿った一対の桁をも含んでいる。加えて、支柱の前記内側壁は、ベースプレートの外側面に接する側壁である。
更に、前記柱における上下複数の貫通孔は、係る柱の下部を内外方向に沿って貫通するが、後述する中空部を有する支柱では、その内側壁に形成される。 The inner side surface of the base plate is a side surface in contact with the side surface of the beam or girder, and the outer side surface is a side surface opposite to the inner side surface. Further, the base plate having the concave groove may be formed from an extruded shape of an aluminum alloy, for example. Further, the concave portion is a portion where the central portion of the inner side surface of the base plate is recessed, and the base plate having the concave portion is formed by countersinking one surface of various metal plates including an aluminum alloy. Also good. In addition to the rectangular cross-section, the concave groove of the base plate may be a wide-bottomed groove having an opening having a cross section wider than the bottom. In this case, the cross section of the nut plate fitted into the wide groove is substantially trapezoidal or substantially inverted T-shaped. Further, a gap that allows tilting of the nut plate is formed between the concave groove and the concave portion and the width direction of the nut plate, but the gap is a clearance within a design tolerance range, Larger dimensions are desirable.
The girder includes an inclined stair girder and includes a girder along one side surface in the longitudinal direction of the staircase and a pair of girder along both side surfaces of the staircase. In addition, the inner side wall of the support column is a side wall in contact with the outer side surface of the base plate.
Further, the plurality of upper and lower through holes in the pillar penetrate the lower part of the pillar along the inner and outer directions, but are formed on the inner wall of the pillar having a hollow portion described later.

また、本発明には、前記支柱の各貫通孔は、縦長の長孔である、手摺用支柱の取付構造（請求項２）も含まれる。
これによれば、前記のように、ベースプレートを梁などの側面における所定の位置で、垂直線に対し左右方向の何れかに極く僅かの傾きを伴って固定した場合でも、係るベースプレートにおける上下複数の横長の長孔と、支柱における複数の縦長の長孔との双方を活用することができる。従って、これらの長孔を貫通する固定ボルトの位置を調整することで、上記傾きを矯正し且つ所定の高さに揃えて、支柱を一層容易に取り付けることができる。 The present invention also includes a handrail support mounting structure (claim 2) in which each through hole of the support post is a vertically long hole.
According to this, as described above, even when the base plate is fixed at a predetermined position on the side surface of the beam or the like with a slight inclination in any of the left and right directions with respect to the vertical line, a plurality of upper and lower portions of the base plate are arranged. It is possible to utilize both the horizontally long slots and the plurality of vertically long slots in the column. Therefore, by adjusting the position of the fixing bolt that passes through these long holes, the inclination can be corrected and the struts can be attached more easily with a predetermined height.

更に、本発明には、前記ベースプレートの凹溝または凹部の深さと前記ナット板の板厚とがほぼ同じあると共に、上記凹溝または凹部とナット板とは、側面視でほぼ相似形の長方形または正方形を呈する、手摺用支柱の取付構造（請求項３）も含まれる。
これによれば、ナット板をベースプレートの凹溝または凹部に嵌装した際、係るベースプレートおよびナット板の内側面を、ほぼ面一にできるため、予め、上記嵌装をしておくことで、現場への搬入が容易となる。しかも、ベースプレートを梁などの側面に固定した際には、当該梁の側面を過度に損傷する事態を防ぐことも可能となる。
尚、上記凹溝は、ベースプレートの内側面を上辺から下辺まで貫通する形態の他、ベースプレートの内側面の上辺にのみ開口し、係る凹溝の下端がベースプレートの内側面の途中で閉じた形態としても良い。係る形態で且つ底面が開口部よりも幅広の底広凹溝とした場合、断面ほぼ台形やほぼ逆Ｔ字形のナット板を落下させずに、嵌装した状態で容易且つ安全に現場にセットすることができる。 Further, in the present invention, the depth of the groove or recess of the base plate is substantially the same as the thickness of the nut plate, and the groove or recess and the nut plate have a rectangular shape or a substantially similar shape when viewed from the side. A mounting structure for a handrail post that exhibits a square shape (Claim 3) is also included.
According to this, when the nut plate is fitted into the concave groove or the concave portion of the base plate, the inner side surfaces of the base plate and the nut plate can be substantially flush with each other. It becomes easy to carry in. In addition, when the base plate is fixed to a side surface such as a beam, it is possible to prevent a situation in which the side surface of the beam is excessively damaged.
In addition to the form that penetrates the inner surface of the base plate from the upper side to the lower side, the groove is opened only on the upper side of the inner surface of the base plate, and the lower end of the groove is closed in the middle of the inner surface of the base plate. Also good. When the bottom is a wide groove with a bottom that is wider than the opening, the nut plate having a substantially trapezoidal cross section or a substantially inverted T-shape is not dropped and can be easily and safely set in the field. be able to.

また、本発明には、前記支柱は、断面ほぼ角形で且つ垂直方向に沿って中空部を有すると共に、前記各貫通孔に連通し、且つ前記各固定用ボルトの雄ネジ部を貫通させる通し孔を有する座金が上記中空部に挿入されている、手摺用支柱の取付構造（請求項４）も含まれる。
これによれば、例えば、支柱がアルミニウム合金の中空形材からなる場合、係る支柱の内側壁に形成する複数の貫通孔を固定用ボルトが貫通しても、上記アルミニウム合金よりも高強度の鋼板やステンレス鋼板などからなる座金を用いることで、上記貫通孔を当初の形状に容易に保つことができる。特に、支柱の貫通孔が縦長の長孔である場合には、その変形を一層確実に防ぐことが可能となる。
尚、本発明の対象となる支柱は、上記中空部を有しない中実材であっても良く、係る支柱を用いる形態では、複数の前記固定ボルトごとのボルト頭を収容可能な複数の窪み、または垂直な窪み溝を、当該支柱の外側面に形成することが望ましい。係る中実材の支柱には、角形鋼、角形ステンレス鋼、断面が角形のアルミニウム合金からなる棒（バー）材、あるいは硬質の樹脂材または木材が適用される。 Further, according to the present invention, the support column has a substantially square cross section and has a hollow portion along the vertical direction, and communicates with the through holes and through the male screw portions of the fixing bolts. Also included is a mounting structure for a handrail support (claim 4) in which a washer having a shape is inserted into the hollow portion.
According to this, for example, when the support column is made of an aluminum alloy hollow shape, even if the fixing bolt passes through a plurality of through holes formed in the inner wall of the support column, the steel plate has higher strength than the aluminum alloy. By using a washer made of stainless steel plate or the like, the through hole can be easily kept in its original shape. In particular, when the through hole of the support column is a vertically long slot, the deformation can be prevented more reliably.
In addition, the support | pillar used as the object of this invention may be a solid material which does not have the said hollow part, and in the form using such a support | pillar, several hollow which can accommodate the bolt head for every said some fixed bolt, Or it is desirable to form a vertical hollow in the outer surface of the said support | pillar. For such solid material struts, a square steel, a square stainless steel, a bar (bar) material made of an aluminum alloy having a square cross section, or a hard resin material or wood is applied.

加えて、本発明には、前記支柱は、前記梁または桁の側面に間隔を置いて、前記ベースプレート、ナット板、および固定ボルトを介して複数個が固定されると共に、隣接する支柱同士の上部または間に、笠木、複数の格子を有する柵体、または、パネルの少なくとも１つが取り付けられる、手摺用支柱の取付構造（請求項５）も含まれる。
これによれば、ベースプレートの取り付け具合に影響されることなく、複数の支柱を、梁や桁の側面に垂直で且つ同じ高さに揃えるか、一定の傾斜角度に沿って揃えて立設できるため、係る複数の支柱の間に各種デザインの柵体やパネルが容易に且つ体裁良く取り付けることができる。加えて、複数の支柱の上端にまたがって、笠木を水平または所定の傾斜を伴って取り付けることもできる。従って、設計時の基本意匠を保った手摺を容易に施工することが可能となる。 In addition, according to the present invention, a plurality of the support columns are fixed to each other through the base plate, the nut plate, and the fixing bolt at intervals on the side surfaces of the beams or girders. In addition, an attachment structure for a handrail support (claim 5) to which at least one of a headboard, a fence body having a plurality of lattices, or a panel is attached is also included.
According to this, it is possible to stand upright by aligning a plurality of struts perpendicular to the side surface of the beam or girder and at the same height, or along a certain inclination angle without being affected by the mounting condition of the base plate. Thus, various designs of fences and panels can be easily and well attached between the plurality of columns. In addition, the headboard can be mounted horizontally or with a predetermined inclination across the upper ends of the plurality of columns. Therefore, it is possible to easily construct a handrail that maintains the basic design at the time of design.

支柱２は、アルミニウム合金の中空押出形材からなり、断面ほぼ角形で且つほぼ正方形の中空部３を垂直（長手）方向に沿って有し、その下部の外側壁には、上下一対の挿通孔４およびこれを塞ぐキャップ５を有する共に、内側壁における上記挿通孔４と同じ高さの位置には、上下一対（複数）の貫通孔２ａを有している。係る支柱２の中空部３の下部には、上記一対の貫通孔２ａと同軸心となる上下一対の通し孔２２を有する座金２０が、内側壁に接蝕して挿入される。
尚、上記キャップ５は、樹脂製の成形品であるが、これに替えて貼り付けシールにしても良く、上記座金２０は、例えば、鋼板またはステンレス鋼板からなる。 As shown in FIGS. 2 to 4, the mounting structure of the handrail support 2 according to the present invention is formed along a plurality of base plates 10 fixed to the side surface of the beam H and the inner side surface 12 of the base plate 10 along the vertical direction. A nut plate 18 fitted in the recessed groove 13 having a rectangular cross section, and a support column 2 fixed to the outer surface 14 of the base plate 10 with its lower portion in contact therewith. The base plate 10 is composed of a plate body 11 that is formed of, for example, an aluminum alloy extruded shape and has a substantially rectangular parallelepiped shape.
The support column 2 is made of an aluminum alloy hollow extruded shape, and has a hollow portion 3 having a substantially square cross section and a substantially square shape along the vertical (longitudinal) direction, and a pair of upper and lower insertion holes in the lower outer wall. 4 and a cap 5 for closing the same, and a pair of upper and lower (a plurality of) through-holes 2a at the same height as the insertion hole 4 on the inner wall. A washer 20 having a pair of upper and lower through holes 22 coaxial with the pair of through holes 2a is inserted into the lower portion of the hollow portion 3 of the support column 2 in contact with the inner wall.
The cap 5 is a resin molded product, but may be affixed with a sticker instead. The washer 20 is made of, for example, a steel plate or a stainless steel plate.

また、図３，４に示すように、ベースプレート１０は、そのプレート本体１１の四隅における内側面１２と外側面１４との間を大径穴１５と小径穴１６とが同軸心で貫通している。係るプレート本体１１の内側面１２の中央部を垂直方向に沿って貫通する凹溝１３の底面と外側面１４との間には、上下一対（複数）の横長（長軸が水平向き）の長孔（長円形孔）１７が貫通している。係る一対の長孔１７，１７間のピッチは、支柱２の貫通孔２ａ，２ａ間および挿通孔４，４間のピッチ、更には、座金２０の通し孔２２，２２間のピッチと同じである。
更に、ナット板１８も、例えば、鋼板またはステンレス鋼板からなり、図２〜図４に示すように、前記凹溝１３の深さとほぼ同じ板厚で、且つ側面視で係る凹溝１３とほぼ相似形の長方形で且つ全体が直方体を呈すると共に、上下一対の雌ネジ孔１９を有している。係る雌ネジ孔１９，１９間のピッチも、ベースプレート１０の長孔１７，１７間、支柱２の貫通孔２ａ，２ａ間、および挿通孔４，４間のピッチと同じである。尚、ナット板１８の幅寸法は、前記凹溝１３の幅寸法よりも若干小さく設定され、係る凹溝１３内での傾動を可能としている。 As shown in FIGS. 3 and 4, the base plate 10 has a large-diameter hole 15 and a small-diameter hole 16 coaxially passing between the inner surface 12 and the outer surface 14 at the four corners of the plate body 11. . Between the bottom surface and the outer surface 14 of the concave groove 13 penetrating the central portion of the inner side surface 12 of the plate body 11 along the vertical direction, a pair of upper and lower (plural) horizontally long (long axis is horizontal) length. A hole (oval hole) 17 passes therethrough. The pitch between the pair of long holes 17 and 17 is the same as the pitch between the through holes 2a and 2a of the support column 2 and between the insertion holes 4 and 4, and further, the pitch between the through holes 22 and 22 of the washer 20. .
Further, the nut plate 18 is also made of, for example, a steel plate or a stainless steel plate, and as shown in FIGS. 2 to 4, has a thickness substantially the same as the depth of the concave groove 13 and is substantially similar to the concave groove 13 in a side view. The shape is rectangular and the whole is a rectangular parallelepiped, and has a pair of upper and lower female screw holes 19. The pitch between the female screw holes 19, 19 is the same as the pitch between the long holes 17, 17 of the base plate 10, between the through holes 2 a, 2 a of the support column 2, and between the insertion holes 4, 4. Note that the width dimension of the nut plate 18 is set slightly smaller than the width dimension of the concave groove 13 so that tilting in the concave groove 13 is possible.

前記手摺１を施工する際し、手摺用支柱２の取付構造は、次のようにして活用される。先ず、図２〜図４に示すように、ベースプレート１０の凹溝１３にナット板１８を嵌装し、一対の長孔１７と一対の雌ネジ孔１９とを連通させる。
この際、図３に示すように、ナット板１８と凹溝１３との間には、左右一対の隙間ｓが形成される。また、ナット板１８が外れないように、例えば、図示しないテープをベースプレート１０の底面に予め貼り付けておくと良い。
次いで、凹溝１３にナット板１８を嵌装したベースプレート１０を、そのプレート本体１１における四隅の大径穴１５から小径穴１６に向かってこれらを貫通するボルトｂを、梁Ｈの側面からネジ込む。この結果、図１に示すように、当該ベースプレート１０を梁Ｈの側面に等間隔で固定する。その後、上記大径穴１５の開口部は、例えば、ベースプレート１０と同色のキャップｃにより閉塞され、且つ各キャップｃの表面は、ベースプレート１０の外側面１４と面一とされる。 When constructing the handrail 1, the attachment structure of the handrail support 2 is utilized as follows. First, as shown in FIGS. 2 to 4, a nut plate 18 is fitted into the groove 13 of the base plate 10, and the pair of long holes 17 and the pair of female screw holes 19 are communicated with each other.
At this time, as shown in FIG. 3, a pair of left and right gaps s is formed between the nut plate 18 and the groove 13. Further, for example, a tape (not shown) may be attached in advance to the bottom surface of the base plate 10 so that the nut plate 18 does not come off.
Next, the base plate 10 in which the nut plate 18 is fitted in the concave groove 13 is screwed in from the side surface of the beam H with the bolt b passing therethrough from the large-diameter hole 15 at the four corners toward the small-diameter hole 16 in the plate body 11. . As a result, the base plate 10 is fixed to the side surface of the beam H at regular intervals as shown in FIG. Thereafter, the opening of the large-diameter hole 15 is closed by, for example, a cap c of the same color as the base plate 10, and the surface of each cap c is flush with the outer surface 14 of the base plate 10.

次に、図２，３に示すように、中空部３の下部にテープ（図示せず）などで仮止めしつつ座金２０をセットした支柱２を、各ベースプレート１０の外側面１４に接触させる。係る状態で、図４中の太い矢印で示すように、頭に六角穴ｈを有する２本の固定用ボルトＢを、各支柱２の挿通孔４、座金２０の通し孔２２、各支柱２の貫通孔２ａ、およびベースプレート１０の長孔１７に順次貫通させた後、上記各ボルトＢの雄ネジ部をナット板１８の各雌ネジ孔１９に螺合させる。尚、ベースプレート１０の底面に貼り付けた前記テープは、適時に剥離される。
この結果、図１，図２に示すように、複数の支柱２は、梁Ｈの側面に垂直で且つ高さを揃えた状態で取り付けられる。更に、隣接する支柱２，２の間には、柵体６の上・下桟７，８の端部が図示しない金具を介して固定される。
最後に、複数の支柱２の上端に固定した金具ｋを介して、笠木Ｔを固定して支持することにより、図１に示すように、手摺１が設計の通りにして施工される。 Next, as shown in FIGS. 2 and 3, the support column 2 in which the washer 20 is set while being temporarily fixed with a tape (not shown) or the like below the hollow portion 3 is brought into contact with the outer side surface 14 of each base plate 10. In this state, as shown by the thick arrows in FIG. 4, the two fixing bolts B having the hexagonal holes h at the heads are inserted into the insertion holes 4 of the columns 2, the through holes 22 of the washers 20, and the columns 2. After sequentially passing through the through hole 2 a and the long hole 17 of the base plate 10, the male screw portion of each bolt B is screwed into each female screw hole 19 of the nut plate 18. Note that the tape attached to the bottom surface of the base plate 10 is peeled off in a timely manner.
As a result, as shown in FIGS. 1 and 2, the plurality of struts 2 are attached in a state where they are perpendicular to the side surface of the beam H and have the same height. Further, the end portions of the upper and lower rails 7 and 8 of the fence body 6 are fixed between adjacent struts 2 and 2 through metal fittings (not shown).
Finally, the handrail 1 is constructed as designed as shown in FIG. 1 by fixing and supporting the headboard T through the metal fitting k fixed to the upper ends of the plurality of columns 2.

ところで、凹溝１３にナット板１８を嵌装したベースプレート１０は、図５に示すように、梁Ｈの側面に固定する際、図示で右側に極く僅か（例えば、１度未満）に傾斜した姿勢で４本のボルトｂにより固定される場合がある。
係る場合には、図５に示すように、ベースプレート１０の上下一対の長孔１７のうち、上方の長孔１７の中央から極く僅か左側に固定用ボルトＢを貫通させると共に、下方の長孔１７の中央から極く僅か右側に固定用ボルトＢを貫通させるように、前記各隙間ｓを利用してナット板１８を傾動させて、支柱２を取り付ける。この結果、係る支柱２を垂直姿勢で確実に立設できると共に、その高さを隣接する支柱２と揃える操作が、現場で容易に行うことができる。
従って、本発明による手摺１用支柱２の取付構造を用いることで、手摺１を梁Ｈの外側に設計通りのデザインにして容易且つ確実に施工することができる。 By the way, as shown in FIG. 5, the base plate 10 in which the nut plate 18 is fitted in the concave groove 13 is tilted to the right side in the drawing very slightly (for example, less than 1 degree) when being fixed to the side surface of the beam H. It may be fixed by four bolts b in the posture.
In such a case, as shown in FIG. 5, among the pair of upper and lower long holes 17 of the base plate 10, the fixing bolt B is penetrated to the left slightly from the center of the upper long hole 17 and the lower long hole The support plate 2 is attached by tilting the nut plate 18 using the gaps s so that the fixing bolt B is penetrated slightly to the right side from the center of 17. As a result, the support column 2 can be reliably erected in a vertical posture, and the operation of aligning the height of the support column 2 with the adjacent support column 2 can be easily performed on site.
Therefore, by using the mounting structure for the handrail 1 support 2 according to the present invention, the handrail 1 can be easily and reliably constructed on the outside of the beam H with a design as designed.

図６は、前記形態の応用形態の支柱２の取付構造を示す分解斜視図である。
係る支柱２の取付構造が前記の形態と相違するところは、支柱２の内側壁に設ける複数の貫通孔を、上下一対（複数）の縦長（長軸が垂直向き）の長孔（長円形孔）３ｂ，３ｂとしている点である。これにより、前記図５で示したように、ベースプレート１０およびその凹溝１３に嵌装したナット板１８を、梁Ｈの側面に対し傾斜して固定した際には、ベースプレート１０の横長の各長孔１７と共に、上記支柱２の縦長の各長孔３ｂを併せて活用することができる。この結果、支柱２を垂直姿勢で確実に立設でき、その高さを隣接する支柱２と揃える操作を、現場にて一層容易で確実に行うことが可能となる。 FIG. 6 is an exploded perspective view showing the mounting structure of the support column 2 according to the application form of the above embodiment.
The mounting structure of the support column 2 is different from the above-described configuration in that a plurality of through holes provided in the inner wall of the support column 2 are a pair of upper and lower (multiple) vertically long (long axis is vertically oriented) long holes (oval holes). 3b, 3b. Accordingly, as shown in FIG. 5, when the nut plate 18 fitted in the base plate 10 and the recessed groove 13 is fixed to the side surface of the beam H while being inclined, Together with the holes 17, the vertically long slots 3 b of the support column 2 can be used together. As a result, the support column 2 can be reliably set up in a vertical posture, and the operation of aligning the height of the support column 2 with the adjacent support column 2 can be performed more easily and reliably at the site.

図７は、異なる形態の支柱２４を用いた前記図３と同様な水平断面図、図８は、係る支柱２４を用いる取付構造の要部を示す前記図４と同様な分解斜視図である。
図７，図８に示すように、支柱２４は、例えばステンレス鋼からなり、断面が長方形（角形）である棒状の本体２５と、その外側面の下部に形成され且つ係る外側面に開口する上下一対の窪み２６と、各窪み２６の底面中央部から内側面に向かって水平に貫通すると貫通孔２７とを有している。上記窪み２６は、座ぐり加工によって全体が円柱形に形成されているが、係る形状に限るものではない。
前記同様にして、ベースプレート１０は、その凹溝１３にナット板１８を嵌装した状態で、梁Ｈの側面に固定され、この際に、ベースプレート１０の横長の各長孔１７と、ナット板１８の各雌ネジ孔１９とは、互いに連通すると共に、係るナット板１８と凹溝１３との間には、左右一対の隙間ｓが形成される。 FIG. 7 is a horizontal sectional view similar to FIG. 3 using the column 24 of a different form, and FIG. 8 is an exploded perspective view similar to FIG. 4 showing the main part of the mounting structure using the column 24.
As shown in FIGS. 7 and 8, the support column 24 is made of, for example, stainless steel, and has a rod-shaped main body 25 having a rectangular (square) cross section, and upper and lower portions formed at the lower portion of the outer surface and open to the outer surface. A pair of recesses 26 and a through hole 27 are formed when horizontally penetrating from the center of the bottom surface of each recess 26 toward the inner surface. The recess 26 is entirely formed in a cylindrical shape by spot facing, but is not limited to this shape.
In the same manner as described above, the base plate 10 is fixed to the side surface of the beam H with the nut plate 18 fitted in the concave groove 13, and at this time, the horizontally long slots 17 of the base plate 10 and the nut plate 18. The female screw holes 19 communicate with each other, and a pair of left and right gaps s are formed between the nut plate 18 and the groove 13.

係る状態で、支柱２４を、各ベースプレート１０の外側面１４に接触させ、図８中の太い矢印で示すように、頭に六角穴ｈを有する２本の固定用ボルトＢを、各支柱２４の貫通孔２７とベースプレート１０の長孔１７にと順次貫通させた後、上記各ボルトＢの雄ネジ部をナット板１８の各雌ネジ孔１９に螺合させる。
その結果、図７に示すように、支柱２４は、２本の固定用ボルトＢおよびナット板１８を介して、ベースプレート１０の外側面１４に垂直姿勢で固定され且つ梁Ｈの側面に立設される。尚、係る支柱２４の各窪み２６は、当該支柱２４の外側面に貼り付けられる樹脂製の丸いシールＳによって目隠しされる。
更に、隣接する支柱２４，２４の間に、前記同様に柵体６の上・下桟７，８の端部が図示しない金具を介して固定された後、複数の支柱２４の上端に固定した金具ｋを介して、笠木Ｔを固定して支持することにより、前記図１に示した同様ような手摺が設計の通りにして施工される。
尚、前記上下一対の窪み２６に替えて、垂直方向に沿った単一の窪み溝を支柱２４の外側面に形成し、前記ボルトＢを用いて固定した後で、係る窪み溝をことほぼ相似形のシールまたはキャップで塞いでも良い。また、支柱２４の下部を貫通する上下一対の貫通孔２７に替えて、それぞれを縦長の長孔として良い。 In this state, the support column 24 is brought into contact with the outer surface 14 of each base plate 10, and two fixing bolts B each having a hexagonal hole h at the head are attached to each support plate 24 as indicated by a thick arrow in FIG. 8. After sequentially penetrating through the through hole 27 and the long hole 17 of the base plate 10, the male screw portion of each bolt B is screwed into each female screw hole 19 of the nut plate 18.
As a result, as shown in FIG. 7, the column 24 is fixed to the outer surface 14 of the base plate 10 in a vertical posture via the two fixing bolts B and the nut plate 18, and is erected on the side surface of the beam H. The In addition, each hollow 26 of the support | pillar 24 is blindfolded with the resin-made round seal | sticker S affixed on the outer surface of the said support | pillar 24 concerned.
Further, the end portions of the upper and lower rails 7 and 8 of the fence body 6 are fixed between the adjacent support columns 24 and 24 through a metal fitting (not shown) in the same manner as described above, and then fixed to the upper ends of the plurality of support columns 24. By fixing and supporting the headboard T via the metal fitting k, the handrail similar to that shown in FIG. 1 is constructed as designed.
Instead of the pair of upper and lower recesses 26, a single recess groove along the vertical direction is formed on the outer surface of the support column 24 and fixed with the bolt B, and then the recess grooves are substantially similar. It may be closed with a shaped seal or cap. Further, instead of the pair of upper and lower through holes 27 penetrating the lower part of the support column 24, each may be a vertically long slot.

前記同様に、ベースプレート１０は、梁Ｈの側面に固定する際、右側または左側に極く僅か（例えば、１度未満）に傾斜した姿勢で４本のボルトｂにより固定される場合がある。係る場合にも、ベースプレート１０の上下一対の長孔１７のうち、上方の長孔１７の中央から極く僅か左／右側に固定用ボルトＢを貫通させると共に、下方の長孔１７の中央から極く僅か右／左側に固定用ボルトＢを貫通させるように、前記各隙間ｓを利用してナット板１８を傾動させて、支柱２４を取り付けるようにする。この結果、係る支柱２４を垂直姿勢で立設できると共に、その高さを隣接する支柱２４と揃える操作が、現場で容易に行うことができる。
従って、手摺用支柱２４の取付構造を用いることで、前記手摺１と同様な手摺を梁Ｈの外側に設計通りのデザインにして容易且つ確実に施工することができる。 Similarly to the above, when the base plate 10 is fixed to the side surface of the beam H, the base plate 10 may be fixed by the four bolts b in a posture inclined very slightly (for example, less than 1 degree) to the right side or the left side. Also in this case, among the pair of upper and lower long holes 17 of the base plate 10, the fixing bolt B is penetrated slightly left / right from the center of the upper long hole 17 and the pole from the center of the lower long hole 17. The nut plate 18 is tilted by using the gaps s so that the fixing bolt B is penetrated slightly to the right / left side, and the column 24 is attached. As a result, the support 24 can be erected in a vertical posture, and the operation of aligning the height of the support 24 with the adjacent support 24 can be easily performed on site.
Therefore, by using the attachment structure of the handrail support 24, a handrail similar to the handrail 1 can be easily and reliably applied to the outside of the beam H with a design as designed.
