Description
【０００１】[0001]
この考案は、蹴上げ高さの調節を可能とした階段用の踏段に関する。 The present invention relates to a step for stairs that enables adjustment of a kicking height.
【０００２】[0002]
従来、階段を構成する踏段４０で、踏板３３の前側３５下面に蹴込み板３７の 上端側を一体に連設して断面逆Ｌ字状に形成したものでは、踏段４０を階段状に 並べ、ささら桁４１に取り付けて階段４２を構成していた。この場合、下方に位 置する踏段４０の踏板３３の上面３６の後側３４と、上方に隣接する踏段４０の 蹴込み板３７の下面３８とを対応させて、踏段４０、４０を階段状に並べていた （図６）。 Conventionally, in the steps 40 that form a staircase, in which the upper end side of the riser plate 37 is integrally connected to the lower surface of the front side 35 of the step board 33 to form an inverted L-shaped cross section, the steps 40 are arranged in a staircase shape. It was attached to the sasara girder 41 to form the stairs 42. In this case, the rear side 34 of the upper surface 36 of the step plate 33 of the step 40 located below and the lower surface 38 of the riser plate 37 of the step 40 adjacent to the upper side are made to correspond to each other, and the steps 40, 40 are formed in a stepwise manner. They were lined up (Fig. 6).
【０００３】[0003]
前記従来の踏段４０では、一つの踏段４０を異なる蹴上げ高さで使用する場合 、前記踏段４０では、当初蹴上げ高さＨ0 から、上方に位置する踏段を高さＨだ け上昇させて、蹴上げ高さをＨ1 とした場合（図６、鎖線図示４０ａ）、該踏段 ４０ａの蹴込み板３７下面３８と下方の踏段４０の踏板３３の上面３６後側３５ との間に、上昇させた距離Ｈと同量の間隙４３を生じていた。従って、該間隙４ ３を塞ぐ作業が煩雑となると共に該間隙４３は、蹴込み板３７の下方に形成され るので、階段４２の外観を悪くする問題点があった。In the conventional step 40, when one step 40 is used at different kicking heights, the step 40 is lifted from the initial kicking height H 0 by only the height H to raise the kicking step. When the height is H 1 (FIG. 6, chain line 40a), the distance raised between the lower surface 38 of the riser plate 37 of the step 40a and the upper surface 36 rear side 35 of the step plate 33 of the lower step 40 is increased. The same amount of gap 43 as H was generated. Therefore, the work of closing the gap 43 becomes complicated and the gap 43 is formed below the riser plate 37, which causes a problem that the appearance of the stairs 42 is deteriorated.
【０００４】[0004]
然るにこの考案は、階段を構成する踏板の後側端面に形成した対向面と、蹴込 み板の前面に形成した被連結面とを略平行に形成したので、前記問題点を解決し た。 However, the present invention solves the above-mentioned problems because the facing surface formed on the rear end surface of the tread forming the stairs and the connected surface formed on the front surface of the riser plate are formed substantially parallel to each other.
【０００５】 即ちこの考案は、階段状に並列して両端部をささら桁で固定して階段を構成す る踏段において、踏板の前側下面に蹴込み板の上端側を一体に連設してなる断面 逆Ｌ字状で、かつ両側にささら桁取付け用の固定部を有する踏段本体を形成し、 該踏段本体の前記踏板の後側端面に形成した対向面と、蹴込み板の下端側前面に 形成した被対向面とを略平行に形成したことを特徴とする階段用の踏段である。That is, according to the invention, in a step forming a stair in which both ends are fixed in parallel with each other with a girder, and the upper end side of the riser plate is integrally connected to the lower surface of the front side of the step plate. A step body having an inverted L-shape in cross section and having fixing portions for mounting a girder on both sides is formed, and an opposing surface formed on a rear end surface of the step plate of the step body and a lower end front surface of the riser plate are formed. It is a step for stairs, characterized in that the formed face to be opposed is formed substantially in parallel.
【０００６】 また、階段状に並列して両端部をささら桁で固定して階段を構成する踏段にお いて、踏板の前側下面に蹴込み板の上端側を、取付角度が鋭角となるように、一 体に連設してなる断面逆Ｌ字状で、かつ両側にささら桁取付け用の固定部を有す る踏段本体を形成し、該踏段本体の前記踏板の後側端面に形成した対向面と、蹴 込み板の下端側前面に形成した被対向面とを略平行に形成したことを特徴とする 階段用の踏段である。In addition, in a step forming a stair by arranging both ends in parallel with each other and fixing the both ends with a flat girder, the upper end side of the riser plate is attached to the lower surface of the front side of the step plate so that the mounting angle becomes an acute angle. , A step body having an inverted L-shaped cross section formed integrally and having fixing portions for mounting a girder on both sides, and facing each other formed on the rear end surface of the step plate of the step body. It is a step for stairs, characterized in that the surface and the face to be opposed formed on the lower end side front surface of the riser plate are formed substantially parallel to each other.
【０００７】 また、階段状に並列して両端部をささら桁で固定して階段を構成する踏段にお いて、踏板の前側下面に蹴込み板の上端側を、取付角度が鋭角となるように、一 体に連設してなる断面逆Ｌ字状で、かつ両側にささら桁取付け用の固定部を有す る踏段本体を形成し、該踏段本体の前記踏板の後側端面に形成した対向面と、蹴 込み板の下端側前面に形成した被対向面とを略平行に形成し、前記踏板の前側上 面に幅方向の凹凸条を形成したことを特徴とする階段用の踏段である。更に、階 段状に並列して両端部をささら桁で固定して階段を構成する踏段において、踏板 の前側下面に蹴込み板の上端側を、取付角度が鋭角となるように、一体に連設し てなる断面逆Ｌ字状で、かつ両側にささら桁取付け用の固定部を有する踏段本体 を形成し、該踏段本体の前記踏板の後側端面に形成した対向面と、蹴込み板の下 端側前面に形成した被対向面とを略平行に形成し、前記踏板の一側上面に、幅方 向のほぼ全長に亘り、上面に敷設物取付手段を有する取付部材を埋設した階段用 の踏段である。In addition, in a step forming a stair by arranging both ends in parallel with each other in a staircase and fixing it with a flat girder, the upper end side of the riser plate is attached to the lower surface on the front side of the step plate so that the mounting angle becomes an acute angle. , A step body having an inverted L-shaped cross section formed integrally and having fixing portions for mounting a girder on both sides, and facing each other formed on the rear end surface of the step plate of the step body. It is a step for stairs, characterized in that a surface and a surface to be opposed formed on the lower end side front surface of the riser plate are formed substantially parallel to each other, and an uneven strip in the width direction is formed on the front upper surface of the tread plate. . Furthermore, in a step where the two ends are fixed in parallel with each other and fixed with sasara girders to form stairs, the upper end side of the riser plate is integrally connected to the lower front side of the step plate so that the mounting angle is acute. A step body having an inverted L-shape in cross section and having fixing portions for mounting the girder on both sides is formed, and the facing surface formed on the rear end surface of the step plate of the step body and the riser plate. For stairs in which the facing surface formed on the lower end side front surface is formed substantially in parallel, and a mounting member having laying member mounting means is embedded on the upper surface of one side of the tread plate over substantially the entire length in the width direction. It is a step.
【０００８】 前記における取付角度とは、踏板の上面と、蹴込み板前面の上側とがなす角度 をさす。The above-mentioned attachment angle means the angle formed by the upper surface of the tread plate and the upper side of the front surface of the riser plate.
【０００９】[0009]
【作用】 踏板の後側端面に形成した対向面と、蹴込み板の下端側前面に形成した被対向 面とを略平行に形成したので、踏段を階段状に並べた際に、下方に位置する踏段 の対向面と、上方に位置する踏段の被対向面とは互いに対向して、設置される。 踏板の前側下面に蹴込み板の上端側を、取付角度が鋭角となるように形成したも のでは、同じ踏面で、踏板の上面を広く形成できる。[Operation] Since the facing surface formed on the rear end surface of the tread plate and the facing surface formed on the lower end side front surface of the riser plate are formed substantially parallel to each other, when the steps are arranged in a stepwise manner, they are positioned downward. The facing surface of the step and the facing surface of the step located above are installed so as to face each other. If the upper end side of the riser plate is formed on the lower surface of the front side of the tread plate so that the mounting angle is an acute angle, the upper surface of the tread plate can be formed wider with the same tread surface.
【００１０】 前記踏板の前側上面に幅方向の凹凸条を形成したものでは、該部が滑り止めと なる。敷設物取付手段を有する取付部材を埋設したものでは、踏段に各種仕上げ 材を設置できる。In the case where an uneven strip in the width direction is formed on the front upper surface of the tread, the portion serves as a slip stopper. If the mounting member having the laying object mounting means is buried, various finishing materials can be installed on the steps.
【００１１】[0011]
図面に基づきこの考案の実施例を説明する。 An embodiment of the present invention will be described with reference to the drawings.
【００１２】 踏板１の前側２下面５に、蹴込み板８の上端側９を、取付角度（踏板１の上面 ４と蹴込み板８の前面１１とのなす角）α1 が鋭角（ここでは、約８０度）とな るように、一体に連設して、断面逆Ｌ字状の踏段本体１６を形成する。前記踏段 本体１６の踏板１内には、両側にささら桁取付け用のナット１５、１５を連結し た補強鉄筋１４、１４が埋設され、踏板１の両側端面１ａ、１ｂにはナット１５ の螺穴（ささら桁取付け用の固定部）が露出している。On the lower surface 5 of the front side 2 of the tread plate 1, the upper end side 9 of the riser plate 8 is attached at an acute angle (here, the angle between the upper surface 4 of the tread plate 1 and the front face 11 of the riser plate) α 1. , About 80 degrees) are integrally connected to form a step body 16 having an inverted L-shaped cross section. Reinforcing reinforcing bars 14 and 14 connecting nuts 15 and 15 for mounting girder girders on both sides are embedded in the step plate 1 of the step body 16 and screw holes for the nut 15 are formed on both end surfaces 1a and 1b of the step plate 1. (Fixing part for mounting the sasara girder) is exposed.
【００１３】 前記踏板１の後側３の端面６の上面４側を対向面１７とし、また前記蹴込み板 ８の前面１１は、平面状に形成され、前記蹴込み板８の前面１１下端側１１ｂを 被対向面１８とする。ここで、前記被対向面１８と下方に位置する予定の踏段の 上面（水平面）４ａとのなす角α2 は、前記取付角度α1 と同一に形成される。 前記踏段本体１６の踏板１の対向面１７を、該対向面１７の延長線１７ａと踏板 １の上面４とがなす角度をβとする。前記角度βを、前記取付角度α1 （＝α2 ）と同一に形成する。従って、踏板１の対向面１７と蹴込み板８の被対向面１８ とは平行に形成される。The upper surface 4 side of the end surface 6 of the rear side 3 of the tread plate 1 is the facing surface 17, and the front surface 11 of the riser plate 8 is formed in a flat shape, and the lower end side of the front face 11 of the riser plate 8 is formed. Let 11b be the opposed surface 18. Here, the angle α 2 formed between the opposed surface 18 and the upper surface (horizontal surface) 4a of the step to be located below is the same as the mounting angle α 1 . The angle between the facing surface 17 of the step plate 1 of the step body 16 and the extension line 17a of the facing surface 17 and the upper surface 4 of the step plate 1 is β. The angle β is formed to be the same as the attachment angle α 1 (= α 2 ). Therefore, the facing surface 17 of the tread 1 and the facing surface 18 of the riser plate 8 are formed in parallel.
【００１４】 また、前記踏板１の上面４の前側２には、幅方向の凹凸条１９、１９が形成さ れている。以上のようにして、踏段２０を形成する。前記踏段２０は、セメント 系（例えば、繊維で補強したモルタル製）材質で、一体に形成されている。Further, on the front side 2 of the upper surface 4 of the tread 1, ridges 19 and 19 are formed in the width direction. The steps 20 are formed as described above. The steps 20 are made of cement (for example, fiber-reinforced mortar) material and are integrally formed.
【００１５】 次に、前記実施例に基づくこの考案の踏段２０の使用について説明する。Next, the use of the step 20 of the present invention based on the above embodiment will be described.
【００１６】 この考案の踏段２０、２０を所定数、階段状に並べ、両端をささら桁２１、２ ２で挟み、ささら桁２１、２２の透孔２３、２３からボルトを挿通し、踏段２０ のナット１５、１５に螺合締結して階段２４を構成する（図１（ａ）、図２）。A predetermined number of steps 20 and 20 of the present invention are arranged in a stepwise manner, both ends are sandwiched by sasara girders 21 and 22, and bolts are inserted through the through holes 23 and 23 of the sasara girders 21 and 22. The stairs 24 are configured by screwing and fastening the nuts 15 and 15 (FIGS. 1A and 2).
【００１７】 また、１つの踏段２０を異なる蹴上げ高さで使用することもできる。この場合 、通常の設置位置（図２の実線位置。蹴上げ高さＨ0 ）では、踏板１の対向面１ ７と蹴込み板８の被対向面１８とは、当接している。通常の使用位置からから、 高さＨだけ上げて、蹴上げ高さＨ1 で使用する場合、例えば、階段２０の上方に 位置する踏段２０を高さＨだけ垂直に上昇させる（図２の鎖線２０ａ位置。蹴上 げ高さＨ1 ）。この時、上方に位置する踏段２０ａの被対向面１８と下方に位置 する踏段の対向面１７とに生じる間隙２５は幅Ｄに過ぎず、高さＨに比べ小さな 量となり、該間隙２５に充填するコーキング量も従来に比して少量で済む。また 、前記間隙２５は踏板１上面４の後側３の端縁側に生じるので、歩行者には目立 たない。It is also possible to use one step 20 with different raising heights. In this case, the facing surface 17 of the tread 1 and the facing surface 18 of the striking plate 8 are in contact with each other at a normal installation position (solid line position in FIG. 2, kicking height H 0 ). When the height H is raised from the normal use position and the kicking height H 1 is used, for example, the step 20 located above the stairs 20 is vertically raised by the height H (a chain line 20a in FIG. 2). Position: Kicking height H 1 ). At this time, the gap 25 formed between the facing surface 18 of the step 20a located above and the facing surface 17 of the step located below is only the width D, which is smaller than the height H, and the gap 25 is filled. The amount of caulking required is smaller than before. Moreover, since the gap 25 is formed on the edge side of the rear side 3 of the upper surface 4 of the tread 1, it is inconspicuous to a pedestrian.
【００１８】 また、ここで、階段２０の上方に位置する踏段を高さＨだけ垂直に上昇させた が、下方の踏段２０の対向面１７と、上方に位置する踏段の被対向面１８とを当 接した状態で、上方に位置する踏段２０ａを高さＨだけ上昇させれば、対向面１ ７と被対向面１８との間の間隙は生じない（図３）。ただし、踏み面は、その分 短くなる。Although the steps located above the stairs 20 are vertically raised by the height H, the facing surface 17 of the lower step 20 and the facing surface 18 of the upper step are stepped up. If the step 20a located above is raised by the height H in the abutting state, the gap between the facing surface 17 and the facing surface 18 does not occur (FIG. 3). However, the tread becomes shorter accordingly.
【００１９】 前記実施例において、取付角度α1 を約８０度としたが、鋭角であれば、他の 角度とすることもでき、通常は７０度乃至９０度で、適宜選択して、設定する。 また、取付角度を９０度とした場合には、階段の上方に位置する踏段を高さＨだ け垂直に上昇させた場合でも、対向面１７と被対向面１８との間の間隙２５は生 じない（図示していない）。In the above-mentioned embodiment, the mounting angle α 1 is set to about 80 degrees, but it can be set to another angle as long as it is an acute angle, usually 70 degrees to 90 degrees, and appropriately selected and set. . Further, when the mounting angle is 90 degrees, the gap 25 between the facing surface 17 and the facing surface 18 is generated even when the step located above the stairs is raised vertically by the height H. I do not (not shown).
【００２０】 また、前記実施例において、対向面１７と被対向面１８とを平行に形成したが 、両面１７、１８は略平行であれば、同様に間隙２５の幅Ｄを微小に形成するこ とができる。Further, although the facing surface 17 and the facing surface 18 are formed parallel to each other in the above-described embodiment, if the both surfaces 17 and 18 are substantially parallel to each other, the width D of the gap 25 may be formed minutely. You can
【００２１】 また、前記実施例において、蹴込み板８の前面１１は平面状に形成したが、蹴 込み板の前面１１の上側１１ａと下側１１ｂを角度を有する形状とすることもで きる。即ち、蹴込み板８の前面上側１１ａ、即ち取付角度α1 を約８０度で形成 し、前面下側１１ｂを垂直に下方に形成して被対向面１８とし、被対向面１８と 下方に位置する予定の踏段の上面（水平面）４ａとのなす角α2 は、９０度で形 成する。この際には、対向面１７の角度βは角度α2 と同じ９０度で形成されて いる（図４）。Further, in the above-mentioned embodiment, the front surface 11 of the riser plate 8 is formed in a flat shape, but it is also possible to form the upper side 11a and the lower side 11b of the front side 11 of the riser plate so as to have an angle. That is, the front side upper side 11a of the riser plate 8, that is, the mounting angle α 1 is formed at about 80 degrees, and the front side lower side 11b is formed vertically downward so as to be the opposed surface 18, which is located below the opposed surface 18. The angle α 2 formed with the upper surface (horizontal plane) 4a of the step to be formed is 90 degrees. At this time, the angle β of the facing surface 17 is formed at 90 degrees, which is the same as the angle α 2 (FIG. 4).
【００２２】 この際、前記と同様に、蹴上げ高さをＨ0 からＨ1 へＨだけ上昇させた場合に 、上方の踏段２０ａを垂直に上昇させても、角度α2 、βはいずれも９０度であ るので、対向面１７と被対向面１８とは当接した状態であり、間隙２５は生じな い（図４）。At this time, similarly to the above, when the raising height is raised from H 0 to H 1 by H, even if the upper step 20a is raised vertically, the angles α 2 and β are both 90 Therefore, the facing surface 17 and the facing surface 18 are in contact with each other, and the gap 25 does not occur (FIG. 4).
【００２３】 また、前記実施例において、前記踏板１の上面４の前側２に、幅方向の凹凸条 １９、１９を形成したが、凹凸条１９は形成しないこともできる（図示していな い）。また、凹凸条１９は歩行時の滑り止めの作用をするが、凹凸条１９に代え て、踏板１の上面４の前側２に、断面略長方形の中空状の取付部材２６を埋設し て、踏段２９を形成することもできる（図５（ａ））。前記において、取付部材 ２６の上面２７には、滑り止め材（敷設物）を固定する為のボルト孔（敷設物取 付手段）を形成してあり（図示していない）、下面にはコンクリートとの定着用 の突条２８を形成してある。この踏段２９は、蹴込み板８の前面１１に蹴込み板 カバー３０を付設すると共に、取付部材２６に踏板カバー付き滑り止めシート３ １をボルトにて取り付ける（図５（ｂ））。ここで、敷設物取付手段をボルト孔 としたが、透孔、両面粘着テープ、その他付設物を挟持、掛止などできる構造と すこともできる（図示していない）。Further, in the above-described embodiment, the width-direction uneven strips 19 and 19 are formed on the front side 2 of the upper surface 4 of the tread 1, but the uneven strips 19 may not be formed (not shown). . Further, although the uneven strip 19 acts as a non-slip during walking, instead of the uneven strip 19, a hollow mounting member 26 having a substantially rectangular cross section is embedded in the front side 2 of the upper surface 4 of the tread 1 to form a step. 29 can also be formed (FIG. 5A). In the above description, the upper surface 27 of the mounting member 26 is provided with a bolt hole (laying material mounting means) for fixing the slip preventing material (laying material) (not shown), and the lower surface is made of concrete. A ridge 28 for fixing is formed. In this step 29, a riser plate cover 30 is attached to the front surface 11 of the riser plate 8, and a slip plate sheet 31 with a step plate cover is attached to the attachment member 26 with bolts (FIG. 5 (b)). Here, the laying object attaching means is a bolt hole, but it is also possible to adopt a structure (not shown) in which a through hole, a double-sided adhesive tape, and other attached objects can be clamped or hooked.
【００２４】 また、前記実施例において、補強材は両端部のナット１５の螺穴を、踏板１の 両側端面１ａ、１ｂに露出させ、該部をささら桁取付け用の固定部としたが、全 長に亘る螺筒を補強材として埋設することもできる。また、棒状補強材の両端部 に螺糸を形成し、該部を踏段の側縁から突出させ、固定部とすることもできる。In addition, in the above-described embodiment, the reinforcing material exposes the screw holes of the nuts 15 at both ends to both end surfaces 1a and 1b of the tread 1, and the portions are used as the fixing portions for mounting the smooth girder. It is also possible to embed a long threaded cylinder as a reinforcing material. Alternatively, a thread may be formed at both ends of the rod-shaped reinforcing member, and the thread may be projected from the side edge of the step to serve as a fixed portion.
【００２５】[0025]
階段を構成する踏板の後側端面に形成した対向面と、蹴込み板の下端側前面に 形成した被対向面とを略平行に形成したので、踏段を階段状に並べ階段を構成し た際に、隣接する踏段の対向面と被対向面とを互いに対向して設置すれば、１つ の踏段を種々の蹴上げ高さで使用しても、隣接する階段に生じる間隙を微小にで きるので、該間隙を埋める手間が省け、階段の施工を簡略化できる効果がある。 また、１つの踏段を種々の蹴上げ高さで使用できるので、蹴上げ高さに応じて、 数種類の踏段を用意する必要がなく、踏段の製造から施工までを効率化できる効 果がある。 Since the facing surface formed on the rear end surface of the step plate that forms the stairs and the facing surface formed on the lower end side front surface of the riser plate are formed substantially parallel to each other, when the steps are arranged in a staircase pattern, the stairs are formed. In addition, if the facing surface and the facing surface of the adjacent steps are installed so as to face each other, even if one step is used at various raising heights, the gap generated in the adjacent steps can be made minute. Therefore, there is an effect that the labor for filling the gap can be saved and the construction of the stairs can be simplified. In addition, since one step can be used at various lift heights, it is not necessary to prepare several kinds of steps according to the lift height, and there is an effect that the steps from manufacturing to construction can be made efficient.
【００２６】 また、踏板の前側下面に蹴込み板の上端側を、取付角度が鋭角となるように形 成したものでは、同じ踏面で踏板の上面を広く形成でるので、階段使用者の爪先 が踏板に当たらないと共に、前記隣接階段間の間隙を更に目立たなくする効果が ある。Further, in the case where the upper end side of the riser plate is formed on the lower surface of the front side of the tread plate so that the mounting angle becomes an acute angle, the upper surface of the tread plate can be formed wide with the same tread surface, so that the toe of the stair user can be It has the effect of not hitting the treads and making the gap between the adjacent stairs even less noticeable.
【００２７】 前記踏板の前側上面に幅方向の凹凸条を形成し、あるいは敷設物取付手段を有 する取付部材を埋設したものでは、階段の滑りを防止し、踏段に所望の仕上げ材 を設置することができる。[0027] In the case where the front side upper surface of the tread plate is formed with an uneven strip in the width direction or the mounting member having a laying object mounting means is embedded, the stairs are prevented from slipping and a desired finishing material is installed on the step. be able to.
