Description

【考案の詳細な説明】 【0001】 【考案の属する技術分野】 本考案は、棒状階段部材に関し、より詳しくは、山野に施設される歩道用階段 に使用する棒状階段部材に関する。 【0002】 【従来技術】 全国の公園における遊歩道や山岳地域の登山道には、勾配の急なところを中心 に多数の階段が設置されており、この階段としては、間伐材を所定の長さに切断 したものを、所要の蹴上げ高さとなるように積み重ね、両側を木製杭により固定 た構造が一般的である。 【0003】 日本のような多雨地帯、特に雨の多い山地帯においては、降雨時には上方から の雨水による表層流が踏面や階段側方の土砂を道の側方へ押し流しながら、階段 の両側を流れるようになり、側方部の土砂が表層流により削られ、歩道の側方の 路盤が表層流の流路として定着することとなり、階段が周囲の地形よりも相対的 浮き上がってしまうことが多く、その結果、歩行者にとっては蹴上げが高くなる ため、階段を利用せずに土砂の削られた側方を通行するようになる。そのため、 側方の土砂がより一層流失しやすくなるという悪循環が繰り返されて、蹴上げを 小さくし、踏面の勾配を緩やかにして歩きやすくするという歩道用階段の効用が 比較的短期間で失われることになる。 【0004】 このため、公園における遊歩道や山岳地域の登山道における歩道用安全階段と して、降雨時における上方からの表層流を階段中央に集約することにより、側方 の土砂の流出・痩せを防止し、併せて踏面に土砂を継続的に供給することを可能 とし、踏面を安定的な堆砂勾配に維持し、これにより階段設置の効果期間を大幅 に延長しうるものとして、踏面の端部に棒状階段部材を設置してなる歩道用安全 階段において、前記棒状階段部材における踏面中央部を凹部としてなる歩道用安 全階段が提案されている(特開平11−71709号公報)。 【0005】 しかしながら、前述の構成を有する歩道用の安全階段にあっては、棒状階段部 材として丸太を使用する場合、降雨時においては必然的に地盤に弛みを生じた、 この階段の踏面を登山者が踏んだ場合、棒状階段部材が登山者の重量体重により 回動する虞を有するもので、棒状階段部材が回動することで足元の安定を欠き、 転倒する危険性を有し、また、この棒状階段部材を角材とするためには、加工に 時間と経費を要し、棒状階段部材として適切ではない。 【0006】 【特許文献1】 特開平11−71709号公報 【0007】 【考案が解決しようとする課題】 前述の諸点に鑑み、本考案は棒状階段部材として踏面を登山者が踏んだ場合に あっても、回動する事の無い、長期間に亘って安定した歩道用の安全階段を構築 することのできる棒状階段部材を提供することを目的とする。 【0008】 【課題を解決するための手段】 上述の課題を解決するための本考案に係る構成は、棒状部材の表面全体、また は、表面の一部に棒状部材の軸心と並行に1以上の凹溝を削設した点に存する。 【0009】 【考案の実施の形態】 本考案において、棒状階段部材としては、間伐材などの丸太及びプラスチック やコンクリートなどの木材以外の素材を用いて棒状に加工したものを用いること ができる。 【0010】 図1に示すように、棒状階段部材1は、表面全体に棒状部材の軸心と並行に1 以上の凹溝2を削設する。この結果、棒状階段部材1の外周面には複数の突条3 が形成される。例えば、棒状階段部材1として間伐材の丸太を用いた場合、丸太 の直径が12〜14cm程度の場合、凹部の深さは1.5〜3cm程度が好まし い。 【0011】 棒状階段部材1は、表面の一部にのみ棒状部材の軸心と並行に1以上の凹溝2 を削設することも可能で、例えば、棒状階段部材1の半周に亘って凹溝2を削設 することも可能で、さらには、削設する凹溝2のピッチについても不規則(ラン ダム)に設けることも可能である。 【0012】 遊歩道や山岳地域の登山道における歩道用安全階段として本考案にかかる棒状 階段部材1を使用するに際しては、適宜の長さに切断された棒状階段部材1の両 側を、鉄製アーム、金属ボルト、杭などの適宜な固定部材により、歩道の踏面端 部に固定する。棒状階段部材1は、歩道用安全階段として、蹴上げ4は低い方が 歩きやすいため、1段で設置するのが好ましいが、図2に示すように上下に2段 に重ねて使用してもよい。 【0013】 例えば、図2に示すように、棒状階段部材1を上下に2段に重ねて使用する場 合、上下の棒状階段部材1は凹溝2を削設されて形成された突条3と凹溝2とが 相互に噛合うように積み重ね、その両側を杭5により固定する。この様に積み重 ねることで、それぞれが土中に埋没されることとなり、土圧の作用によって前記 凹溝2内に土が侵入することで地盤と棒状階段部材1とが強固に結合されること から、階段全体として強固な構造体となり、また、表面に突条3が露出すること から、棒状階段部材1の上を登山者が踏んだ場合、滑り止めの効果を有するとと もに、上下の棒状階段部材1は地盤の土と強固に結合していることから、雨天時 における地盤の弛んだ状態にあっても棒状階段部材1の回動することを阻止し、 不安定となることを防止する。 【0014】 【考案の効果】 本考案の棒状階段部材によれば、丸太や疑似丸太などの棒状階段部材の表面に 凹溝を削設し、言い換えれば、突条を形成しているため、歩行者の靴底が滑りに くく、また、棒状階段部材が土との結合がなされるために荷重が作用することに よって回動することが防止されることから、安全な歩行を可能にする歩道用階段 とすることができる。 【0016】 また、本考案の棒状階段部材はより側方の土砂の流出を防止し、踏面を安定的 な堆砂勾配に維持できる。これらにより階段設置の効果期間を大幅に延長するこ ともできる。[Detailed description of the invention] [0001] [Technical field to which the invention belongs]   The present invention relates to a bar-shaped stair member, and more particularly, to a sidewalk stair provided in Yamano. The present invention relates to a bar-shaped staircase member used for: [0002] [Prior art]   The promenades in parks nationwide and the trails in mountainous areas are mainly steep Many stairs are set up in this area. Are piled up to the required rise height and fixed on both sides with wooden piles Structure is common. [0003]   In a rainy region like Japan, especially in a mountainous region with heavy rain, when raining, The surface current caused by rainwater in the stairs sweeps the soil on the side of the treads and stairs to the side of the road, Flow on both sides of the sidewalk, and the sediment on the side is cut off by surface flow, The subbase will be established as a surface flow channel, and the stairs will be more relative to the surrounding terrain. Often lifted, resulting in higher kick-ups for pedestrians As a result, they will pass on the side where the sand has been cut without using the stairs. for that reason, The vicious cycle that the soil on the sides is more likely to run off is repeated, The effect of the sidewalk stairs is to make it smaller, make the treads gentler, and make it easier to walk. It will be lost in a relatively short time. [0004]   For this reason, safety stairs for sidewalks on promenades in parks and mountain trails in mountainous areas By collecting surface flow from above during rainfall at the center of the stairs, Prevent the outflow and thinning of the soil, and at the same time, continuously supply the soil to the treads To maintain a stable sedimentation gradient, which significantly increases the effective period of stairs installation. Sidewalk safety with bar-shaped steps at the end of the tread as extendable In the stairs, a sidewalk safety member having a concave portion at the center of the tread surface of the bar-shaped stair member. All stairs have been proposed (Japanese Patent Laid-Open No. 11-71709). [0005]   However, in the sidewalk safety stairs having the above-described configuration, the bar-shaped stairs are used. When logs are used as materials, the ground inevitably loosened during rainfall. If a climber steps on the steps of this stair, There is a risk of rotation, and the rod-shaped stair member rotates, lacking stability at the feet, There is a risk of falling over, and in order to make this rod-shaped step It requires time and money, and is not suitable as a bar-shaped step member. [0006]   [Patent Document 1] Japanese Patent Laid-Open No. 11-71709 [0007] [Problems to be solved by the invention]   In view of the above-mentioned points, the present invention is applied to a case where a climber steps on a tread as a bar-shaped stair member. Construct safety stairs for sidewalks that are stable for a long time without turning even if there is It is an object of the present invention to provide a bar-shaped step member that can be used. [0008] [Means for Solving the Problems]   The configuration according to the present invention for solving the above-described problems includes the entire surface of the rod-shaped member, Is that one or more concave grooves are cut in a part of the surface in parallel with the axis of the rod-shaped member. [0009]   [Embodiment of the invention]   In the present invention, logs and plastics such as thinned wood are used as the bar-shaped steps. Use materials processed into bars using materials other than wood, such as concrete or concrete Can be. [0010]   As shown in FIG. 1, the bar-shaped staircase member 1 has an entire surface parallel to the axis of the bar-shaped member. The above-mentioned concave groove 2 is cut out. As a result, a plurality of ridges 3 are formed on the outer peripheral surface of the rod-shaped step member 1. Is formed. For example, when a log of thinned wood is used as the bar-shaped staircase member 1, When the diameter of the recess is about 12 to 14 cm, the depth of the recess is preferably about 1.5 to 3 cm. No. [0011]   The bar-shaped step member 1 has at least one concave groove 2 parallel to the axis of the bar only on a part of the surface. It is also possible to cut a groove 2 over a half circumference of the bar-shaped step member 1, for example. The pitch of the groove 2 to be cut is also irregular (running). (Dam). [0012]   The stick shape according to the present invention is used as a safety stair for sidewalks on promenades and mountain trails in mountainous areas When using the staircase member 1, the both ends of the bar-shaped staircase member 1 cut to an appropriate length are used. On the side, use a suitable fixing member such as an iron arm, metal bolt, or pile to secure the tread edge of the sidewalk. To the part. The bar-shaped staircase member 1 is a sidewalk safety staircase, Because it is easy to walk, it is preferable to install in one step, but as shown in FIG. May also be used. [0013]   For example, as shown in FIG. In the case, the upper and lower bar-shaped staircase members 1 are formed with the ridges 3 formed by cutting the concave grooves 2 and the concave grooves 2. They are stacked so as to mesh with each other, and both sides thereof are fixed by the pile 5. Pile up like this By bedding, each will be buried in the soil, by the action of earth pressure The soil and the bar-shaped staircase member 1 are firmly connected to each other due to the intrusion of soil into the concave groove 2. Therefore, the stairs become a strong structure as a whole, and the ridges 3 are exposed on the surface. It is said that when a climber steps on the bar-shaped staircase member 1, it has an anti-slip effect. Since the upper and lower bar-shaped steps 1 are firmly connected to the soil of the ground, To prevent the rod-shaped staircase member 1 from rotating even when the ground is loosened, Prevent instability. [0014] [Effect of the invention]   According to the bar-shaped step member of the present invention, the surface of the bar-shaped step member such as a log and a pseudo log is formed. The pits are slipped because the grooves are cut out, in other words, the ridges are formed. In addition, the load is applied because the rod-shaped step member is connected to the soil. Therefore, sidewalk stairs that enable safe walking because they are prevented from turning It can be. [0016]   In addition, the bar-shaped stair member of the present invention prevents the outflow of earth and sand from the side and stabilizes the tread surface. It is possible to maintain a good sediment gradient. These will greatly extend the effectiveness of stairs installation. Can also be.
