Description

本考案は、滑り止め効果を有する階段の改良に関する。 The present invention relates to an improvement of a staircase having an anti-slip effect.

例えば、コンクリートや金属製からなる階段には、雨や水や砂等による滑りを防止するために、階段の踏み面の前端部に滑止部材を取り付けることが行われている。滑止部材は、軟性又は硬性の合成樹脂板材の表面の横方向に線状の凹凸部を形成したものが広く一般に用いられている（特許文献１参照）。 For example, in a stair made of concrete or metal, a non-slip member is attached to the front end portion of the tread surface of the stair to prevent slippage due to rain, water, sand, or the like. As the non-slip member, a member in which a linear concavo-convex portion is formed in the lateral direction of the surface of a soft or hard synthetic resin plate is widely used (see Patent Document 1).

しかしながら、合成樹脂製の滑止部材を用いた従来の階段では、滑止部材の摩耗が激しく、長期的に滑り止め効果を持続させることは難しい。とりわけ人通りの多い階段では、損耗が激しく外観性にも劣る。さらには、横方向の線状凹凸部を形成した従来のものでは、横滑りに対する滑り止め効果が低く安全性を欠くおそれがあった。
特開２００５−１５５１８５号公報 However, in the conventional staircase using the non-slip member made of synthetic resin, the anti-slip member is heavily worn, and it is difficult to maintain the anti-slip effect in the long term. In particular, the stairs with many people are very worn and inferior in appearance. Furthermore, in the conventional device in which the linear concavo-convex portions in the horizontal direction are formed, the anti-slip effect against the side slip is low and there is a risk of lacking safety.

図１は、帯状の鋼板材２０よりなる滑止部材１２を固定部材４０、例えばネジ４１で階段の踏み面の前端部に固設した実施例である階段Ｓ１を表している。図２に示すように、滑止部材１２は上面に平坦な梨地状模様部２６からなる滑止部２５が形成されており、固定部材４０を通すためのネジ穴部３０が形成されている。歩行者が躓かないよう固定部材４０の頭と滑止部材１２の天面が、同一平面を構成するよう、滑止部材１２に形成されるネジ穴部３０には面取り加工が施されている。階段Ｓ１は、滑止部材１２が固定部材４０によって固設されるため、接着剤等を用いて階段に設置したものに比べてズレが少なく、耐久性に優れている。また、設置作業の簡略化、短時間化も可能であり、経済的である。 FIG. 1 shows a staircase S1 which is an embodiment in which a non-slip member 12 made of a strip-shaped steel plate material 20 is fixed to a front end portion of a tread surface of a staircase with a fixing member 40, for example, a screw 41. As shown in FIG. 2, the anti-slip member 12 has an anti-skid part 25 formed of a flat textured pattern part 26 on the upper surface, and a screw hole 30 through which the fixing member 40 is passed. The screw hole 30 formed in the anti-slip member 12 is chamfered so that the head of the fixing member 40 and the top surface of the anti-slip member 12 constitute the same plane so that a pedestrian does not scoop. Since the non-slip member 12 is fixed by the fixing member 40, the staircase S1 is less displaced than those installed on the staircase using an adhesive or the like, and has excellent durability. Moreover, the installation work can be simplified and shortened, which is economical.

図３は、断面Ｌ字状の鋼板材２１よりなる滑止部材１３を固定部材４０、例えばネジ４１で階段の踏み面の前端部に固設した実施例である階段Ｓ２を表している。図４に示すように、滑止部材１３は上面に平坦な梨地状模様部２６からなる滑止部２５が形成されており、固定部材４０を通すためのネジ穴部３０が形成されており、帯状に固定される階段Ｓ１と同様に、鋼板材２１の天面と固定部材４０の頭が、同一平面を構成するよう、ネジ穴部３０は面取り加工されている。滑止部材１３は断面Ｌ字状に形成されているので、滑止部材１３のずれや変形が少なく耐久性に優れ長期における設置が可能である。 FIG. 3 shows a staircase S2 which is an embodiment in which a non-slip member 13 made of a steel plate material 21 having an L-shaped cross section is fixed to a front end portion of a stepped surface of a staircase with a fixing member 40, for example, a screw 41. As shown in FIG. 4, the anti-slip member 13 has an anti-skid part 25 formed of a flat satin-like pattern part 26 formed on the upper surface, and a screw hole 30 through which the fixing member 40 is passed. Similarly to the staircase S1 fixed in a belt shape, the screw hole 30 is chamfered so that the top surface of the steel plate material 21 and the head of the fixing member 40 constitute the same plane. Since the non-slip member 13 is formed in an L-shaped cross section, the anti-slip member 13 is less displaced and deformed and has excellent durability and can be installed for a long period of time.

図５，６に示し、請求項１又は４及び５に記載したように、この考案の階段に配設される滑止部材１０，１１は、鋼板材２０，２１の上面に以下述べる工程で形成された梨地状模様部２６からなる滑止部２５を有する。すなわち、滑止部材１０，１１は、鋼板材のスラブ表面をプロパン炎等の炎によってスカーフィングすることで、スラブ表面に生じた傷や不純物を溶削した後、粗圧機で幅出し圧延し、この幅出し圧延された仕掛板を複数の仕上げ圧延機によって圧延し、所定の規格寸法にする。最後の仕上げ圧延機の圧延ロールの表面には、凹凸模様の刻み目を入れた転写ロールを配置し、鉄板の片面に凹凸模様部を転写形成する。次いで、平坦なロールを備えた熱間矯正機の間を通すことによって平坦な梨地状模様部から成る滑止部を作成する。鋼板材の板厚は、この種部材に使用されるものとして一般には３ｍｍ、４．５ｍｍ、６ｍｍ、９ｍｍ等があるが、本実施形態では滑り止め効果を得るという目的のため、３ｍｍ厚の鋼板材を採用し、これを滑止部材１０，１１とした。滑止部材１０，１１は、天面が無数の凹凸で覆われ、全方向への滑り止め効果を有する。 As shown in FIGS. 5 and 6 and described in claim 1 or 4 and 5, the non-slip members 10 and 11 disposed on the stairs of the present invention are formed on the upper surfaces of the steel plate materials 20 and 21 in the following steps. The anti-skid part 25 which consists of the done satin-like pattern part 26 is provided. That is, the non-slip members 10 and 11 scarf the surface of the slab of the steel plate with a flame such as propane flame, and after scuffing scratches and impurities generated on the surface of the slab, rolling out with a roughing machine The in-process plate subjected to the tenter rolling is rolled by a plurality of finish rolling mills to a predetermined standard size. On the surface of the rolling roll of the final finish rolling mill, a transfer roll with notches in the concavo-convex pattern is arranged, and the concavo-convex pattern portion is transferred and formed on one side of the iron plate. Next, a non-slip portion composed of a flat textured pattern portion is created by passing through a hot straightening machine equipped with a flat roll. The plate thickness of the steel plate material is generally 3 mm, 4.5 mm, 6 mm, 9 mm, etc. as used for this kind of member, but for the purpose of obtaining a non-slip effect in this embodiment, a 3 mm thick steel plate A material was employed, which was designated as non-slip members 10 and 11. The top surfaces of the antiskid members 10 and 11 are covered with innumerable irregularities and have an antislip effect in all directions.

図７及び図８に示すように、この滑止部材１０，１１の滑止部２５を形成する梨地状模様部２６の梨地部２７の高さ（ｔ）は、０．２ｍｍ〜１．０ｍｍ、好ましくは０．４ｍｍ〜０．６ｍｍの範囲にあり、十分な滑り止め効果が確保できると共に、歩行者が転んだ場合にも皮膚が削れる等の怪我をすることはない。また、梨地部２７の大きさは、小さい程外観に優れ、縦（Ｙ）、横（Ｘ）それぞれが１０ｍｍ以下、特に５ｍｍ以下に設定することで美しい梨地状模様を得ることができ、さらには、摩擦係数を高めることになり、より高い滑り止め効果が期待される。また、鋼鉄製であることから、頑強であり、人通りが多い場所でも、摩耗が少なく滑り止め効果の長期持続が可能である。 As shown in FIGS. 7 and 8, the height (t) of the satin portion 27 of the satin pattern portion 26 forming the anti-slip portion 25 of the anti-slip members 10 and 11 is 0.2 mm to 1.0 mm, Preferably, it is in the range of 0.4 mm to 0.6 mm, and a sufficient anti-slip effect can be secured, and even when a pedestrian falls, there is no injury such as skin scraping. In addition, the smaller the size of the satin portion 27, the better the appearance, and by setting each of the vertical (Y) and horizontal (X) to 10 mm or less, particularly 5 mm or less, a beautiful satin pattern can be obtained. As a result, the friction coefficient is increased, and a higher anti-slip effect is expected. In addition, because it is made of steel, it is robust, and even in places where there is a lot of traffic, it has little wear and can maintain a non-slip effect for a long time.

図９の滑止部材１４は、鋼板材２１の裏面側にアンカー部５０となるコンクリート埋没固定用の丸鋼５１が溶接によって溶着されている。階段固設時に、丸鋼５１をコンクリートに埋没することにより、滑止部材１４は、簡単な構成で限りなく安定に固定することができ、ズレなどが生じることなく、耐久性に優れている。さらには、製造が容易で経済的である。ここで、丸鋼５１は、異形鉄筋を利用し、そのふしの高さ、間隔、軸線とのなす角度、隙間の合計等を、規格により付着性や疲労特性を考慮して選ばれる。また、図示しないが、一本の丸鋼５１を使用するのではなく、鋼板材に短い丸鋼を一定間隔毎に溶接してもよい。 In the non-slip member 14 of FIG. 9, a round steel 51 for concrete burying and fixing that becomes an anchor portion 50 is welded to the back side of the steel plate material 21 by welding. By embedding the round steel 51 in the concrete at the time of fixing the staircase, the anti-slip member 14 can be fixed stably with a simple structure as much as possible, and is excellent in durability without causing a deviation. Furthermore, it is easy and economical to manufacture. Here, the round steel 51 uses a deformed reinforcing bar, and the height, the interval, the angle formed with the axis, the total gap, and the like are selected according to the standards in consideration of adhesion and fatigue characteristics. Although not shown, instead of using one round steel 51, a short round steel may be welded to the steel plate material at regular intervals.

図１０の滑止部材１５は、鋼板材２０の裏面側にアンカー部５０となるコンクリート埋没固定用のＴ字鋼５２が溶接によって溶着された例である。Ｔ字鋼５２は受部６０の大きさを適宜決定することができる。 The antiskid member 15 of FIG. 10 is an example in which a T-steel 52 for concrete burying and fixing, which becomes the anchor portion 50, is welded to the back side of the steel plate material 20 by welding. The T-shaped steel 52 can appropriately determine the size of the receiving portion 60.

アンカー部５０が形成された階段用滑止部材にあっては、後付の滑止部材に比べ、コンクリートが固定するまでの期間を待つことなく設置が可能で、作業時間の短縮が可能となる。さらには、接着剤等を使うことなく、安定した設置が可能である。また、アンカー部５０の構成は図示するものに限定されるものではなく、その形態を適宜変更することができる。例えば、丸鋼５１やＴ字鋼５２ではなく、Ｌ字鋼を溶接しアンカー部５０とすることも可能である。 In the anti-skid member for stairs in which the anchor part 50 is formed, it is possible to install without waiting for a period until the concrete is fixed, and the working time can be shortened as compared with the anti-slip member attached later. . Furthermore, stable installation is possible without using an adhesive or the like. Moreover, the structure of the anchor part 50 is not limited to what is illustrated, The form can be changed suitably. For example, it is possible to weld the L-shaped steel instead of the round steel 51 and the T-shaped steel 52 to form the anchor portion 50.

図１１及び図１２に示し、請求項８に記載したように、階段面がグレーチングＧである階段の前端部に滑止部材２０，２１を装着することもできる。滑止部材２０，２１はグレーチングＧと同様の鋼鉄製であることから、装着した場合にも強度の面で劣ることはなく、景観を損なうことはない。また、雨天時に歩行者が滑って転ぶ危険性が特に高くなるグレーチングの階段においても、簡易な構成で十分な滑り止め効果を得ることができる。 As shown in FIGS. 11 and 12 and described in claim 8, the antiskid members 20 and 21 can be attached to the front end portion of the staircase whose staircase surface is the grating G. Since the non-slip members 20 and 21 are made of the same steel as the grating G, they are not inferior in terms of strength even when they are attached, and do not impair the scenery. In addition, a sufficient anti-slip effect can be obtained with a simple configuration even in a grating staircase where the risk of a pedestrian slipping and falling in the rain is particularly high.

なお、本考案の階段は、前述の実施例のみに限定されるものではなく、考案の趣旨を逸脱しない範囲において構成の一部を適宜に変更して実施することができる。例えば、車椅子又はベビーカー等が通行可能なスロープ等に、滑止部材２０を一定間隔毎に配設することで、車輪が滑る危険性を減少させることができる。 The staircase of the present invention is not limited to the above-described embodiments, and a part of the configuration can be changed as appropriate without departing from the spirit of the invention. For example, the risk of the wheels slipping can be reduced by disposing the non-slip member 20 at regular intervals on a slope or the like through which a wheelchair or a stroller can pass.
