Description
本発明は、段板、階段および建物に関するものである。 The present invention relates to steps, stairs and buildings.
従来、階段として、段板の踏面に蹴込面を一体に形成した略Ｌ字断面状に形成したり、段板と段板との間に底板部を設けたりして、段板と段板との間の空間部を塞いだものが知られている（例えば、特許文献１〜特許文献３参照）。
また、他の階段として、足を乗せる踏面を形成する段板と段板との間が開放されて、軽量かつ開放感を有して意匠性に優れたものが知られている（例えば、特許文献４、５参照）。
Conventionally, as a staircase, a step plate and a step plate are formed by forming a substantially L-shaped cross section in which a riser surface is integrally formed on the tread surface of the step plate, or by providing a bottom plate portion between the step plate and the step plate. It is known that the space between them is closed (see, for example, Patent Documents 1 to 3).
Further, as another staircase, there is known one in which the space between the step plate forming the tread on which the foot is placed is opened, the stairs are lightweight, have a feeling of openness, and have excellent design (for example, a patent). References 4 and 5).
そして、これらの従来技術では、段板に落下した雨水の排水が考慮されている。
特に、特許文献４，５に記載のもののように、段板と段板との間が開放されたいわゆるオープン階段では、段板と段板との間からの雨水の落下が問題となる。
Then, in these conventional techniques, drainage of rainwater that has fallen on the step board is taken into consideration.
In particular, in a so-called open staircase in which the space between the step plates is open as described in Patent Documents 4 and 5, rainwater falls from between the step plates becomes a problem.
そこで、特許文献４に記載の技術では、段板の奥側端部に蹴込み板が立設され、段板の上面に、左右方向に排水勾配が設けられているとともに、排水勾配の最も低くなった段板の左右端部に溝が形成され、かつ、溝は、下段の段板上に雨水を導くよう奥側から手前側に傾斜されている。
したがって、段板の上面の雨水が奥側に落下するのが蹴込み板により規制されるとともに、排水勾配により左右端部の溝に集められ、この溝から下段の段板に落下することを繰り返し、階段の麓に流れる。よって、階段の下方への雨水の落下を抑制できる。
Therefore, in the technique described in Patent Document 4, a riser plate is erected at the back end of the step plate, and a drainage gradient is provided in the left-right direction on the upper surface of the step plate, and the drainage gradient is the lowest. Grooves are formed at the left and right ends of the stepped plate, and the grooves are inclined from the back side to the front side so as to guide rainwater onto the lower stepped plate.
Therefore, the rainwater on the upper surface of the step plate is regulated by the riser plate from falling to the back side, and is collected in the grooves at the left and right ends due to the drainage gradient, and repeatedly falls from this groove to the lower step plate. , Flowing at the foot of the stairs. Therefore, it is possible to suppress the fall of rainwater to the lower part of the stairs.
また、特許文献５に記載の技術では、段板の奥側端部にリブが立設されるとともに、段板の左右端部に断面略三角形の止水堤部が突出して形成され、かつ、段板の上面の奥側部側から前縁部側に向かう排水勾配が形成されている。
したがって、段板の上面の雨水が奥側および左右に落下するのがリブおよび止水堤部により規制され、かつ、上面の排水勾配により、手前側端部から下段の段板に落下する。そして、これを順次繰り返すことにより、段板上の雨水は、途中に溜まることなく、階段下に排水される。
よって、階段の下方への雨水の落下を抑制できる。
Further, in the technique described in Patent Document 5, ribs are erected at the back end of the step plate, and water stoppages having a substantially triangular cross section are formed at the left and right ends of the step plate. A drainage gradient is formed from the back side of the upper surface of the step plate to the front edge side.
Therefore, the rainwater on the upper surface of the step plate is restricted from falling to the back side and left and right by the ribs and the water stop embankment, and falls from the front end to the lower step plate due to the drainage gradient on the upper surface. Then, by repeating this sequentially, the rainwater on the step board is drained to the bottom of the stairs without accumulating in the middle.
Therefore, it is possible to suppress the fall of rainwater to the lower part of the stairs.
しかしながら、上下の段板の間が開放された特許文献４，５に記載された階段は、開放感が得られるものの、段板の奥側に端部に蹴込み板あるいはリブが立設され、また、左右側部には、溝の一端縁を形成する凸部や、止水堤部が突出して形成されている。
このため、段板のこれらの突出部分に、人が身体の一部をぶつけるおそれがあり、この場合、これらの突出部分を有さないものと比較して、身体へ与えるダメージが大きくなるおそれがある。
However, although the stairs described in Patent Documents 4 and 5 in which the space between the upper and lower step plates is open can provide a feeling of openness, a riser plate or rib is erected at the end on the back side of the step plates, and On the left and right side, a convex portion forming one end edge of the groove and a water stop bank portion are formed so as to project.
For this reason, a person may hit a part of the body against these protruding parts of the step board, and in this case, the damage to the body may be greater than that without these protruding parts. is there.
本発明は、上述の従来の問題に着目して成されたもので、階段下への雨水の落下を抑制でき、さらに、衝突時のダメージ低減可能な段板、階段および建物を提供することを目的としている。 The present invention has been made by paying attention to the above-mentioned conventional problems, and provides a step board, a staircase, and a building that can suppress the fall of rainwater under the stairs and can reduce the damage in the event of a collision.

The step plate 20 is fixed to the sasara girders 10 and 10 via the step plate joint fitting 30 and the step plate receiving metal fitting 40 (see FIG. 3).
The step plate 20 is formed of a structure having strength such as a honeycomb structure made of a recycled plastic composite material, and has a rectangular plate-like tread plate portion 21 extending in the horizontal direction and a tread plate portion 21 in front of the tread plate portion 21. It is formed in an L-shaped cross section by a hanging flange portion 22 hanging from a nose portion (first long side) on the side.
踏板部２１は、踏板部２１の上面は、平滑面に滑り止め用の細かな溝が形成されて滑り止め部２１ａが設けられている。この滑り止め部２１ａの溝部分は全体で連続し、雨水は、この溝部分を後述する排水勾配ＷＳＬ，ＷＳＦＲの方向に伝って流れるように形成されている。このように、踏板部２１は、滑り止め部２１ａとして溝は形成されているものの、外周端縁部２１ｂは、平坦に形成されている。
なお、段板２０の排水勾配ＷＳＬ，ＷＳＦＲの詳細については、後述する。
The tread plate portion 21 is provided with a non-slip portion 21a on the upper surface of the tread plate portion 21 with a smooth surface formed with fine grooves for non-slip. The groove portion of the non-slip portion 21a is continuous as a whole, and rainwater is formed so as to flow along the groove portion in the direction of the drainage gradients WSL and WSFR described later. As described above, the tread plate portion 21 is formed with a groove as the non-slip portion 21a, but the outer peripheral edge portion 21b is formed flat.
The details of the drainage gradients WSL and WSFR of the step plate 20 will be described later.
段板接合金具３０は、図２、図３に示すように、下板３１、側板３２、上板３３により、上下方向の縦断面が略Ｚ形状に形成されている。そして、下板３１が、ささら桁１０の上板１１にボルト５１、ナット５２を締結して固定されている。また、上板３３の下方からタッピンネジ５３を、段板受金具４０を貫通して段板２０に締結し、段板２０を段板接合金具３０に固定している。 As shown in FIGS. 2 and 3, the step plate joint fitting 30 is formed by the lower plate 31, the side plate 32, and the upper plate 33 so that the vertical cross section in the vertical direction is substantially Z-shaped. Then, the lower plate 31 is fixed to the upper plate 11 of the sasara girder 10 by fastening bolts 51 and nuts 52. Further, a tapping screw 53 is fastened to the step plate 20 through the step plate receiving metal fitting 40 from below the upper plate 33, and the step plate 20 is fixed to the step plate joint metal fitting 30.
段板受金具４０は、左右のささら桁１０，１０に固定された左右一対の段板接合金具３０，３０に、左右方向に架け渡され、段板２０への入力荷重を受け止める。この段板受金具４０は、金属製の薄板により形成され、ベース板部４１と踏み抜け防止部４２と奥側フランジ部４３とにより、略逆Ｕ字断面形状に形成されている。 The step plate receiving metal fittings 40 are bridged in the left-right direction to a pair of left and right step plate joining metal fittings 30 and 30 fixed to the left and right sasara girders 10 and 10, and receive an input load on the step plate 20. The step plate receiving metal fitting 40 is formed of a thin metal plate, and is formed in a substantially inverted U-shaped cross section by a base plate portion 41, a step-through prevention portion 42, and a back flange portion 43.
ベース板部４１は、略長方形の平面形状に形成され、その全面が、段板２０の踏板部２１の裏面に接着剤により接着される。
踏み抜け防止部４２は、ベース板部４１の段鼻側の端部から下方に突出され、その下端部は、昇降時に万一、足先が当たった際に引っ掛かることの無いよう踏み面の奥方向に折曲されている。
The base plate portion 41 is formed in a substantially rectangular planar shape, and the entire surface thereof is adhered to the back surface of the tread plate portion 21 of the step plate 20 with an adhesive.
The step-through prevention portion 42 protrudes downward from the end portion of the base plate portion 41 on the nose side, and the lower end portion thereof is in the depth direction of the tread surface so as not to be caught when the toes hit the base plate portion 41. It is bent into.
奥側フランジ部４３は、ベース板部４１の奥側の端部から下方に突出され、踏み抜け防止部４２の上下方向寸法よりも短い寸法に形成されている。なお、段板接合金具３０の上板３３は、踏み抜け防止部４２と奥側フランジ部４３との間に収まる寸法に形成されている。 The back-side flange portion 43 projects downward from the back-side end of the base plate portion 41, and is formed to have a dimension shorter than the vertical dimension of the step-through prevention portion 42. The upper plate 33 of the step plate joint fitting 30 is formed in a size that fits between the step-through prevention portion 42 and the back flange portion 43.
次に、段板２０の雨水などの排水構造について説明する。
図１に示すように、段板２０の垂下フランジ部２２の下端面は、手前方向（矢印ＦＲ方向）側ほど低くなるよう傾斜され、手前側端部に、断面が下方に山形で鋭角の水切部２２ａが形成されている。また、踏板部２１の上面の奥側（矢印ＲＲ側であって第２の長辺側）の端部には、左右方向の全長に亘って水受け溝２１ｃが形成されている。この水受け溝２１ｃは、滑り止め部２１ａに形成した溝部分と同じ深さ形成されている。
Next, the drainage structure of the step plate 20 such as rainwater will be described.
As shown in FIG. 1, the lower end surface of the hanging flange portion 22 of the step plate 20 is inclined so as to be lower toward the front side (arrow FR direction), and the cross section is angled downward and has an acute angle at the front end. The portion 22a is formed. Further, a water receiving groove 21c is formed over the entire length in the left-right direction at the end of the upper surface of the tread plate 21 on the back side (the RR side of the arrow and the second long side). The water receiving groove 21c is formed to have the same depth as the groove portion formed in the non-slip portion 21a.
さらに、段板２０は、下段側の踏板部２１の水受け溝２１ｃと、上段側の段板２０の垂下フランジ部２２の水切部２２ａの手前側端部とが、同一鉛直線上に配置されている。したがって、垂下フランジ部２２の下端面の先端の水切部２２ａにより水切りされて落下する水は、その下段の段板２０の水受け溝２１ｃで受け止められる。 Further, in the step plate 20, the water receiving groove 21c of the tread plate portion 21 on the lower step side and the front end portion of the drainage portion 22a of the hanging flange portion 22 of the step plate 20 on the upper step side are arranged on the same vertical line. There is. Therefore, the water drained and dropped by the draining portion 22a at the tip of the lower end surface of the hanging flange portion 22 is received by the water receiving groove 21c of the lower step plate 20.
次に、段板２０の排水勾配について説明する。
踏板部２１は、図４Ａに示すように、水平方向で左右の一方である左側の端部が右側の端部よりも低くなるように角度θＬの排水勾配ＷＳＬが設定されている。この角度θＬは、僅かであり、例えば、θＬ＝１度程度で、人が傾斜を感じることが無い角度としている。
Next, the drainage gradient of the step plate 20 will be described.
As shown in FIG. 4A, the tread plate portion 21 is set with a drainage gradient WSL having an angle θL so that the left end portion, which is one of the left and right sides in the horizontal direction, is lower than the right end portion. This angle θL is small, for example, θL = about 1 degree, and is an angle at which a person does not feel an inclination.
さらに、踏板部２１は、手前側と奥側とでは、手前側が低くなるように角度θＦＲの排水勾配ＷＳＦＲが形成されている。この排水勾配ＷＳＦＲの角度θＦＲも、θＦＲ＝１度程度で、人が傾斜を感じることが無い角度としている。なお、図では角度θＬ、θＦＲ共に、視覚的に認識できるように、強調して表現している。 Further, the tread plate portion 21 is formed with a drainage gradient WSFR having an angle θFR so that the front side is lower on the front side and the back side. The angle θFR of this drainage gradient WSFR is also set to θFR = about 1 degree so that a person does not feel the inclination. In the figure, both the angles θL and θFR are emphasized so that they can be visually recognized.
上述した排水勾配ＷＳＬは、踏板部２１の上面自体に傾斜を与えた形状に形成してもよいが、段板接合金具３０の上板３３と踏板部２１との間にスペーサなどを介在させて、段板２０自体を、僅かに傾かせて設置してもよい。本実施の形態１では、後者のように、段板２０自体を傾斜させたものとする。 The drainage gradient WSL described above may be formed in a shape in which the upper surface of the tread plate portion 21 itself is inclined, but a spacer or the like is interposed between the upper plate 33 of the step plate joint fitting 30 and the tread plate portion 21. , The step plate 20 itself may be installed with a slight inclination. In the first embodiment, it is assumed that the step plate 20 itself is inclined as in the latter case.
（実施の形態１の作用）
実施の形態１の階段Ａの作用として、踏板部２１に雨水や掃除の際の水などにより濡れた場合の雨水の流れを説明する。
(Action of Embodiment 1)
As the action of the stairs A of the first embodiment, the flow of rainwater when the tread plate portion 21 gets wet with rainwater, water for cleaning, or the like will be described.
上段の段板２０の踏板部２１の上の水は、滑り止め部２１ａの溝を伝い、左右方向の排水勾配ＷＳＬに沿って、左方向に流れるとともに、手前方向の排水勾配ＷＳＦＲに沿って手前方向に流れる。
これにより、踏板部２１の手前側において左側寄りに集まり、さらに、踏板部２１の手前側端部の垂下フランジ部２２に沿って下降し、水切部２２ａにより水切りされて、下段の段板２０の水受け溝２１ｃに落下する。
The water on the tread plate 21 of the upper step plate 20 flows to the left along the drainage gradient WSL in the left-right direction along the groove of the non-slip portion 21a, and flows to the front along the drainage gradient WSFR in the front direction. Flow in the direction.
As a result, the tread plate portion 21 gathers toward the left side on the front side, further descends along the hanging flange portion 22 at the front end portion of the tread plate portion 21, and is drained by the draining portion 22a to form the lower step plate 20. It falls into the water receiving groove 21c.
この下段の段板２０では、水受け溝２１ｃに落下した水および踏板部２１上の水が、滑り止め部２１ａの溝を伝って、上記と同様に、排水勾配ＷＳＬ、ＷＳＦＲに沿って、手前側に集まり、水切部２２ａから下段の段板２０に落下する。これを順次繰り返し、最下段の段板２０から、床などに落下する。 In the lower step plate 20, the water that has fallen into the water receiving groove 21c and the water on the tread plate portion 21 travel through the groove of the non-slip portion 21a, and in the same manner as described above, along the drainage gradients WSL and WSFR, the front side. It gathers on the side and falls from the drainage portion 22a to the lower step plate 20. This is repeated in sequence, and the plate 20 falls from the bottom plate 20 to the floor or the like.
以上のように、本実施の形態１の階段Ａは、上下の段板２０，２０の間が開放され、階段下空間が明るく、意匠性に富む。また、段板２０，２０の間には、段板受金具４０の踏み抜け防止部４２を設けたため、開放感は保ちつつ、階段下から上方向の目線は遮ることができる。 As described above, in the staircase A of the first embodiment, the space between the upper and lower staircase plates 20 and 20 is open, the space under the staircase is bright, and the staircase A is rich in design. Further, since the step-through prevention portion 42 of the step plate receiving metal fitting 40 is provided between the step plates 20 and 20, it is possible to block the line of sight from the bottom of the stairs to the top while maintaining a feeling of openness.
さらに、段板２０の踏板部２１は、全体に平面状に形成し、その外周端縁部２１ｂには、上方や外方に突出した突起部を有しない平坦な形状に形成している。このため、バランスを崩すなどして、踏板部２１の外周端縁部２１ｂに手を掛けた場合などでも、衝撃を与えることがない。 Further, the tread plate portion 21 of the step plate 20 is formed in a flat shape as a whole, and the outer peripheral edge portion 21b thereof is formed in a flat shape having no protrusions protruding upward or outward. Therefore, even if the outer peripheral edge portion 21b of the tread plate portion 21 is touched due to imbalance or the like, no impact is given.
