Description

本考案は、プレハブ式階段に関するものである。   The present invention relates to a prefabricated staircase.

図7から図9は、従来のプレハブ式階段2(例えば、特許文献1参照)を説明するために参照する図である。このプレハブ式階段2は、例えば山間部における登山道や、工事現場等の傾斜面に簡単に取付けることができる階段として使用される。   7 to 9 are views referred to for explaining a conventional prefabricated staircase 2 (see, for example, Patent Document 1). This prefabricated staircase 2 is used, for example, as a staircase that can be easily attached to a mountain road or an inclined surface such as a construction site.

プレハブ式階段2は、図7に示すように、踏み板4と蹴上げ板6とが一体形成された合成樹脂製の、複数のステップ部材8が階段状に配置されて、各ステップ部材8の踏み板4の傾斜面7側の側端部が、この上側の隣合うステップ部材8の蹴上げ板6の下側の側端部と連結されるように組立てられている。   As shown in FIG. 7, the prefabricated staircase 2 includes a plurality of step members 8 made of a synthetic resin in which a foot plate 4 and a kick-up plate 6 are integrally formed, and the step plate 4 of each step member 8. The side end portion on the inclined surface 7 side is assembled with the side end portion on the lower side of the kicking plate 6 of the adjacent step member 8 on the upper side.

ステップ部材8には、図9に示すように、その踏み板4の傾斜面7側の側端部に、上方に高さを有する取付け板部10が一体的に形成されており、ステップ部材8の上側に配置された別のステップ部材8の蹴上げ板6の下側の側端部が、上記ステップ部材8の踏み板4の踏み面4a(上面)に突き当てられると共に、この踏み板4の取付け板部10の、傾斜面7と反対側の面に当接されている。このとき、釘部材12が、蹴上げ板6と踏み板4の取付け板部10を貫通するように打込まれて、ステップ部材8同士が互いに固定されるようになっていた。   As shown in FIG. 9, the step member 8 is integrally formed with a mounting plate portion 10 having a height upward at a side end portion on the inclined surface 7 side of the step plate 4. A lower side end portion of the step-up plate 6 of another step member 8 disposed on the upper side is abutted against a step surface 4a (upper surface) of the step plate 4 of the step member 8, and an attachment plate portion of the step plate 4 10 is in contact with the surface opposite to the inclined surface 7. At this time, the nail member 12 is driven so as to penetrate the lifting plate 6 and the mounting plate portion 10 of the stepping plate 4, and the step members 8 are fixed to each other.

そして、各ステップ部材8には、釘部材12よりも大きな釘のような形状の鋼棒14(釘状部材)が、踏み板4の踏み面4a側から下方に打込まれて貫通しており、この鋼棒14の先端側が傾斜面7の土中に突き刺さることにより、プレハブ式階段2は傾斜面7上に固定されるようになっていた。   And, in each step member 8, a steel bar 14 (nail-like member) shaped like a nail larger than the nail member 12 is driven downward and penetrated from the tread surface 4a side of the tread plate 4, The prefabricated staircase 2 was fixed on the inclined surface 7 by piercing the tip end of the steel bar 14 into the soil of the inclined surface 7.

また、図7及び図8に示すように、最下段のステップ部材8が、傾斜面7に沿う方向の土圧や、降雨時の水流の力等を受けて傾斜面7の下流側に移動しないように、地中に打込まれた鋼棒14よりさらに太い杭16により強固に固定されていた。   As shown in FIGS. 7 and 8, the lowermost step member 8 does not move downstream of the inclined surface 7 due to earth pressure in the direction along the inclined surface 7 or the force of the water flow during rainfall. Thus, it was firmly fixed by the pile 16 that is thicker than the steel rod 14 driven into the ground.

また、プレハブ式階段2の各ステップ部材8は、図8に示すように、一定の長さ寸法で形成されているため、プレハブ式階段2は、ステップ部材8の長さ寸法と同じ長さの幅寸法を有するようになっていた。
登録実用新案第1769991号公報
Further, as shown in FIG. 8, each step member 8 of the prefabricated staircase 2 is formed with a constant length dimension. Therefore, the prefabricated staircase 2 has the same length as that of the step member 8. It had a width dimension.
Registered Utility Model No. 1769991

しかしながら、前記特許文献1に係るプレハブ式階段2にあっては、その使用目的等に応じてその幅寸法(ステップ部材8の長さ方向の寸法)を広げる必要がある場合に、各ステップ部材8の長さ寸法を単に長く形成しようとすると、このステップ部材8が大型化するため、その運搬性が悪化すると共に、長さ寸法が長いステップ部材8を作成するための、大型の金型を用意しなければならないことにより、プレハブ式階段2の大幅なコストアップを招くという問題があった。   However, in the prefabricated staircase 2 according to Patent Document 1, when it is necessary to widen the width dimension (dimension in the length direction of the step member 8) according to the purpose of use, each step member 8 If the length dimension of the step member 8 is simply formed longer, the step member 8 becomes larger, so that the transportability is deteriorated, and a large mold for preparing the step member 8 having a longer length dimension is prepared. As a result, there is a problem that the prefabricated staircase 2 is significantly increased in cost.

そこで本考案は、上記問題点に鑑みて、ステップ部材の運搬性が悪化するのを防止すると共に、大幅なコストアップを招くことを防止することができるプレハブ式階段を提供することを課題とするものである。   Therefore, in view of the above problems, the present invention has an object to provide a prefabricated staircase that can prevent the transportability of the step member from deteriorating and prevent a significant cost increase. Is.

以下、本考案に係るプレハブ式階段の実施の形態について、図面に基づいて具体的に説明する。   Hereinafter, embodiments of a prefabricated staircase according to the present invention will be specifically described with reference to the drawings.

図1ないし図3は、本考案の第1の実施の形態に係るプレハブ式階段20について説明するために参照する図である。これらの図に示すプレハブ式階段20は、従来のプレハブ式階段2と同様の部分には同じ符号を付して説明し、従来と同様の構成についての重複する説明は省略するものとする。   FIGS. 1 to 3 are views referred to for explaining the prefabricated staircase 20 according to the first embodiment of the present invention. In the prefabricated staircase 20 shown in these drawings, the same parts as those of the conventional prefabricated staircase 2 are denoted by the same reference numerals, and redundant description of the same configuration as that of the conventional art will be omitted.

本実施の形態に係るプレハブ式階段20では、図1及び図2に示すように、2つのステップ部材8が、それらの長さ方向に隣合って配置されることにより、それらの踏み板4同士および蹴上げ板6同士が長さ方向に互いに隣合うように並んで配置されている。そして、互いに隣合う2つの踏み板4の端部同士が合成樹脂製の連結板22を介して連結されている。このような2つのステップ部材8が連結板22を介して長さ方向に連結されたものを、連結ステップ部材24ということとする。   In the prefabricated staircase 20 according to the present embodiment, as shown in FIG. 1 and FIG. 2, two step members 8 are arranged adjacent to each other in the length direction, so that the treads 4 and The kick-up plates 6 are arranged side by side so as to be adjacent to each other in the length direction. And the edge parts of the two step boards 4 adjacent to each other are connected through a connecting plate 22 made of synthetic resin. Such two step members 8 connected in the length direction via the connecting plate 22 are referred to as connecting step members 24.

連結板22は、各連結ステップ部材24における、互いに隣合う2つのステップ部材8の踏み板4の両方の端部にわたってそれらの裏面に当接させ、図3に示すように、ボルト26とナット28の締結により踏み板4の両方の端部に固定されている。   The connection plate 22 is brought into contact with the back surface of both the connection step members 24 over both ends of the step plates 4 of the two step members 8 adjacent to each other. As shown in FIG. It is fixed to both ends of the footboard 4 by fastening.

このような本実施の形態に係るプレハブ式階段20によれば、ステップ部材8の運搬性が悪化するのを防止することができると共に、長さ寸法の長いステップ部材8を作成するための大型の金型を用意しなくともプレハブ式階段20の幅寸法を大きくすることができるので、プレハブ式階段20の大幅なコストアップを招くことを防止することができる。   According to such a prefabricated staircase 20 according to the present embodiment, it is possible to prevent deterioration in the transportability of the step member 8 and to make a large-sized step member 8 having a long length. Since the width dimension of the prefabricated staircase 20 can be increased without preparing a mold, it is possible to prevent a significant cost increase of the prefabricated staircase 20.

次に、図4ないし図6は、本考案の第2の実施の形態に係るプレハブ式階段50について説明するために参照する図である。前記第1の実施の形態と同様の部分には同じ符号を用いて説明し、同様の構成についての重複する説明は省略するものとする。   Next, FIG. 4 thru | or FIG. 6 is a figure referred in order to demonstrate the prefabricated staircase 50 which concerns on the 2nd Embodiment of this invention. The same parts as those in the first embodiment will be described using the same reference numerals, and overlapping descriptions of the same configurations will be omitted.

本実施の形態に係るプレハブ式階段50は、図4及び図5に示すように、傾斜面7上に傾斜方向に互いに平行に配置された合成樹脂製の複数の棒状部材52の上に、複数の連結ステップ部材24が、棒状部材52の長さ方向に階段状に並べて固定されている。   As shown in FIGS. 4 and 5, the prefabricated staircase 50 according to the present embodiment includes a plurality of prefabricated staircases 50 on a plurality of bar members 52 made of synthetic resin and arranged in parallel with each other in the inclined direction on the inclined surface 7. The connecting step members 24 are fixed in a stepped manner in the length direction of the rod-shaped member 52.

各連結ステップ部材24を構成する各ステップ部材8の踏み板4には、図6に示すように、この上側に別の連結ステップ部材24が配置される前に、その踏み板4における取付け板部10の近傍に、釘部材54が踏み面4a側から傾斜面7側に向かって打込まれる。   As shown in FIG. 6, before another connecting step member 24 is arranged on the upper side of the step plate 4 of each step member 8 constituting each connecting step member 24, the mounting plate portion 10 of the step plate 4 is arranged. In the vicinity, the nail member 54 is driven from the tread surface 4a side toward the inclined surface 7 side.

このようにして、釘部材54の先端側が、踏み板4の下側の棒状部材52に突き刺さることにより、連結ステップ部材24のステップ部材8の踏み板4は棒状部材52に固定されるようになっている。そして、釘部材54の頭部は、踏み板4の上側に配置される別の連結ステップ部材24の蹴上げ板6の下側に隠れて、外部からは見えないようになっている。   In this way, the front end side of the nail member 54 is stabbed into the bar-like member 52 below the tread board 4, so that the tread board 4 of the step member 8 of the connecting step member 24 is fixed to the bar-like member 52. .
