Description

本発明は、擁壁等の壁面に設置される壁面階段に関する。 The present invention relates to a wall staircase installed on a wall such as a retaining wall.

従来から、擁壁等の壁面に設置される階段が種々開示されている(例えば特許文献1及び特許文献2参照。)。特許文献1に開示された法面設置用階段は、一対の平行に配設されたフレームと、該フレームに懸架されるステップと、上記フレームに立設された支柱と、該支柱によって支持される手摺とからなる階段において、上記ステップは両側が垂直に折曲されてなる軌道プレートを有するものであって、該軌道プレートは上記フレームに回動自在に軸支される為の軸支部を有し、且つ該軸支部を中心とする円弧状を形成するように複数の位置決め孔が貫設されており、上記フレームは法面の傾斜に対応して一定の傾斜角を有して設置されるものであって、上記ステップは法面の傾斜に関係なく常に水平となるように上記複数の位置決め孔の中から一つの位置決め孔が選択されボルトが該位置決め孔及び上記フレームに貫入されて上記ステップが上記フレームに固定されることを特徴とする。 Conventionally, various types of stairs installed on a wall surface such as a retaining wall have been disclosed (see, for example, Patent Document 1 and Patent Document 2). The slope installation staircase disclosed in Patent Document 1 includes a pair of frames arranged in parallel, a step suspended from the frames, a column erected on the frame, and a step supported by the column. In the staircase consisting of a handrail, the step has a track plate whose both sides are bent vertically, and the track plate has a pivot support for rotatably supporting the frame. , and a plurality of positioning holes are penetrated so as to form an arc shape centered on the shaft support, and the frame is installed with a constant inclination angle corresponding to the inclination of the slope. In this step, one positioning hole is selected from among the plurality of positioning holes so that the step is always horizontal regardless of the inclination of the slope, and a bolt is inserted into the positioning hole and the frame. It is characterized in that it is fixed to the frame.

特許文献1に開示された法面設置用階段によると、回動自在に軸支されるステップは、設けるべき法面の状態に応じて自在に角度調整が可能となり、画一的な階段を予め製造していたとしても、様々な状況において対処できることとなり、安価な法面設置用階段を提供できることとなる、と記載されている。 According to the staircase for installation on a slope disclosed in Patent Document 1, the angle of the rotatably supported step can be freely adjusted according to the condition of the slope to be installed, and a uniform staircase can be pre-installed. Even if it were manufactured, it would be possible to deal with various situations, and it would be possible to provide stairs for installation on slopes at low cost.

また、特許文献2に開示された階段用ステップは、壁部に複数個取付けられて、該壁部に片持ち式の階段を形成するためのものであって、壁部に取付けられる固定部の上部より支持部がその長手方向を前方に向けて片持ち状に突出され、該支持部の上面に踏板部が形成されると共に、前記固定部と支持部との間で三角形を形成するように、前記固定部の下部より斜め前方に向けて突出された補強部の先端部が前記支持部に取付けられていることを特徴とする。 Further, the stair steps disclosed in Patent Document 2 are for forming a cantilever type staircase on the wall by attaching a plurality of them to the wall, and the stair steps are for forming a cantilevered staircase on the wall. A support part projects from the upper part in a cantilevered manner with its longitudinal direction facing forward, a step plate part is formed on the upper surface of the support part, and a triangle is formed between the fixed part and the support part. , characterized in that a distal end portion of a reinforcing portion protruding obliquely forward from a lower portion of the fixing portion is attached to the supporting portion.

特許文献2に開示された階段用ステップによると、片持ち式の階段を形成するので、取付ける壁面の角度に合わせて、前後する踏板部が平面視において緩衝しないように、また、隣り合う上下の踏板部の高さ位置を自在に調整して、壁面に取付けることができる。さらに、前記固定部と支持部との間で三角形が形成されるように、前記固定部の下部より斜め前方に向けて突出された補強部の先端部を前記支持部に取付けることにより、片持ち式であっても、踏板部にかかる荷重に対する十分な強度を備えさせることができる、と記載されている。 According to the stair step disclosed in Patent Document 2, a cantilevered staircase is formed, so that the front and rear tread parts are adjusted to the angle of the wall surface to which they are attached so that they do not buffer in plan view, and the adjacent upper and lower steps are You can freely adjust the height of the footboard and attach it to the wall. Furthermore, the tip of the reinforcing part that protrudes diagonally forward from the lower part of the fixing part is attached to the support part so that a triangle is formed between the fixing part and the support part, so that the support part can be cantilevered. It is stated that even with the formula, sufficient strength can be provided to withstand the load applied to the footboard portion.

特許文献1に開示された法面設置用階段や特許文献2に開示された階段用ステップによると、壁面に対して比較的容易に階段を設置することができるものと思料する。 According to the slope installation staircase disclosed in Patent Document 1 and the staircase step disclosed in Patent Document 2, it is considered that the stairs can be installed relatively easily on a wall surface.

しかし、特許文献1に開示された法面設置用階段は、主として一対の平行に配設されたフレームと、このフレームに懸架されるステップとで構成され、法面(壁面)に対して上下方向に真っ直ぐ昇降するタイプの階段である。従って、壁面の角度が急になると、それに伴ってフレームの配設角も急になるため、階段の勾配が急なものとなる。そこで、壁面の角度が急な場合に階段の勾配を緩やかにしようとすると、フレームの下端部分を壁面から大幅に遠ざける必要があり、設置場所の確保や、壁面からフレームが離れていくことによる取付方法の問題等が生じるものと思料する。 However, the stairs for installation on a slope disclosed in Patent Document 1 mainly consist of a pair of parallel frames and a step suspended from the frames, and are arranged in the vertical direction with respect to the slope (wall surface). This is a type of staircase that goes straight up and down. Therefore, when the angle of the wall surface becomes steeper, the angle at which the frame is arranged also becomes steeper, resulting in a steeper slope of the stairs. Therefore, if you try to make the slope of the stairs gentler when the angle of the wall is steep, it is necessary to move the lower end of the frame significantly away from the wall, which makes it difficult to secure an installation location and prevent installation due to the frame moving away from the wall. We believe that there will be problems with the method.

この点、特許文献2に開示された階段用ステップを使用すると、壁面に対して斜め方向に昇降するタイプの階段を設置することができる。従って、壁面の角度に影響を受けることなく、所望の勾配の階段を設置することができる。しかし、特許文献2に開示された階段用ステップは一対で踏板部を支持する構成である。つまり、階段の段数の2倍の階段用ステップを設置する必要があり、非常に手間が掛かるとともに、部品点数も多くなるため、設置コストが高くなるものと思料する。 In this regard, when the stair step disclosed in Patent Document 2 is used, it is possible to install a type of stair that ascends and descends diagonally with respect to a wall surface. Therefore, stairs with a desired slope can be installed without being affected by the angle of the wall surface. However, the stair steps disclosed in Patent Document 2 have a configuration in which a pair of treads are supported. In other words, it is necessary to install twice as many steps as the number of stairs, which is very time-consuming and requires a large number of parts, which is expected to increase the installation cost.

そこで本願発明者は、上記の問題点に鑑み、壁面の角度に影響を受けることなく、所望の勾配の階段を容易且つ安価に設置することができる壁面階段を提供するべく鋭意検討を重ねた結果、本発明に至ったのである。 Therefore, in view of the above-mentioned problems, the inventor of the present application has conducted extensive studies in order to provide a wall staircase that can be easily and inexpensively installed with a staircase of a desired slope without being affected by the angle of the wall surface. This led to the present invention.

即ち、本発明の壁面階段は、擁壁等の壁面に設置される壁面階段であって、固定部材と、支持部材と、保持部材とを含んで構成され、該固定部材の一端部と該支持部材の一端部が連結され、該固定部材の他端部と該保持部材の一端部が連結され、該支持部材の他端部と該保持部材の他端部が連結されて成る複数のブラケットと、踏板部と、蹴込板部とを含んで構成され、側面視が略L字状を成す複数のステップと、前記複数のブラケットに係る各前記支持部材上に架け渡される一対のレールと、を含んで構成され、前記複数のブラケットに係る各前記固定部材が、前記壁面に所定の間隔を空けて階段状に固定され、前記複数のブラケットに係る各前記支持部材上に、前記一対のレールが架け渡され、前記一対のレール上に、前記複数のステップが配設されることを特徴とする。 That is, the wall staircase of the present invention is a wall staircase installed on a wall such as a retaining wall, and includes a fixing member, a supporting member, and a holding member, and includes one end of the fixing member and the supporting member. a plurality of brackets in which one end of the member is connected, the other end of the fixing member and one end of the holding member are connected, and the other end of the supporting member and the other end of the holding member are connected; , a plurality of steps including a tread portion and a riser portion and having a substantially L-shape in side view; and a pair of rails spanning over each of the support members related to the plurality of brackets. each of the fixing members related to the plurality of brackets is fixed to the wall surface in a stepwise manner at predetermined intervals, and the pair of rails are provided on each of the support members related to the plurality of brackets. It is characterized in that the plurality of steps are arranged on the pair of rails, which are bridged over each other.

また、本発明の壁面階段において、前記ステップの幅方向の端部の外側に、前記ステップの昇降方向に沿って所定の間隔を空けて立設される複数の支柱と、前記複数の支柱間に配設される手摺りと、を含んで成ることを特徴とする。 Further, in the wall staircase of the present invention, a plurality of columns are provided outside the ends of the step in the width direction at predetermined intervals along the ascending and descending direction of the steps, and a plurality of columns are provided between the plurality of columns. A handrail is provided.

更に、本発明の壁面階段において、前記ブラケットに係る前記支持部材の他端部側に支柱取付部が配設され、前記支柱取付部に前記支柱が取り付けられることを特徴とする。 Furthermore, the wall staircase of the present invention is characterized in that a pillar attachment part is provided on the other end side of the support member related to the bracket, and the pillar is attached to the pillar attachment part.

また、本発明の壁面階段において、前記一対のレール間に、補強レールが配設されることを特徴とする。 Further, in the wall staircase of the present invention, a reinforcing rail is provided between the pair of rails.

本発明の壁面階段によると、壁面の角度に影響を受けることなく、所望の勾配の階段を容易且つ安価に設置することができる。 According to the wall staircase of the present invention, a staircase with a desired slope can be easily and inexpensively installed without being affected by the angle of the wall surface.

特に、本発明の壁面階段においては、複数のブラケットを所定の間隔を空けて階段状に固定し、この複数のブラケット上に一対のレールを架け渡し、この一対のレール上に複数のステップが配設されるため、ステップ毎にブラケットを配設する必要が無く、設置工事の簡素化や部品点数の削減、これらによる低コスト化等が図られる。 In particular, in the wall staircase of the present invention, a plurality of brackets are fixed at predetermined intervals in a stair-like manner, a pair of rails are spanned over the plurality of brackets, and a plurality of steps are arranged on the pair of rails. Since there is no need to arrange brackets for each step, installation work can be simplified, the number of parts can be reduced, and costs can be reduced due to these.

また、本発明の壁面階段においては、容易に手摺りを設置することも可能であり、安全性の向上を図ることができる。 Further, in the wall staircase of the present invention, a handrail can be easily installed, and safety can be improved.

更に、本発明の壁面階段において、一対のレール間に補強レールを配設することによって、ステップ幅が大きい場合や踊り場等において、安全性の更なる向上を図ることができる。 Further, in the wall staircase of the present invention, by arranging a reinforcing rail between a pair of rails, safety can be further improved when the step width is large or at a landing.

An engagement plate portion 23 is provided to protrude upward from the end of the tread portion 21 opposite to the nosing 21a. Note that the function of the engagement plate portion 23 will be described later.

本実施形態の壁面階段1に係るレール30は、図4(a)に示すように、断面矩形状の角材である。材質は金属製やプラスチック製等、特に限定されないが、強度が確保できればプラスチック製が軽量であるため好ましい。なお、図4(a)及び図4(b)では、レール30及び後述する補強レール32について、これらを水平方向に配設した場合の断面で表している。 The rail 30 according to the wall staircase 1 of this embodiment is a square member with a rectangular cross section, as shown in FIG. 4(a). The material is not particularly limited, such as metal or plastic, but plastic is preferred as it is lightweight as long as it has sufficient strength. Note that in FIGS. 4A and 4B, the rail 30 and the reinforcing rail 32, which will be described later, are shown in cross section when these are arranged in the horizontal direction.

次に、本実施形態の壁面階段1の設置方法について説明する。本実施形態の壁面階段1は、前述したブラケット10、ステップ20及びレール30によって主に構成されており、図1~図3には、本実施形態の壁面階段1を、垂直な壁面Wに設置した態様を示す。 Next, a method for installing the wall staircase 1 of this embodiment will be explained. The wall staircase 1 of this embodiment is mainly composed of the bracket 10, step 20, and rail 30 described above, and FIGS. 1 to 3 show the wall staircase 1 of this embodiment installed on a vertical wall W. This shows how it was done.

まず、複数のブラケット10に係る各固定部材11が、壁面Wに所定の間隔を空けて階段状に固定される。ブラケット10に係る固定部材11は、例えばアンカーボルト(不図示)等によって壁面Wに固定される。 First, the fixing members 11 associated with the plurality of brackets 10 are fixed to the wall surface W at predetermined intervals in a stepped manner. The fixing member 11 of the bracket 10 is fixed to the wall surface W using, for example, an anchor bolt (not shown).

壁面Wに複数のブラケット10が階段状に固定されたら、これら複数のブラケット10に係る各支持部材12上に、一対のレール30が架け渡される。一対のレール30は、支持部材12上に所定の間隔を空けて配設される。レール30と支持部材12との固定方法は特に限定されないが、例えば、断面L型のレール固定金物31をブラケット10に係る支持部材12上にボルトBとナットNで取り付け、このレール固定金物31にレール30をボルトBとナットNで取り付け固定することによって、複数のブラケット10,10間に一対のレール30を架け渡して固定することができる。 Once the plurality of brackets 10 are fixed to the wall surface W in a stepwise manner, a pair of rails 30 is spanned over each support member 12 related to the plurality of brackets 10. The pair of rails 30 are arranged on the support member 12 at a predetermined interval. Although the method of fixing the rail 30 and the support member 12 is not particularly limited, for example, a rail fixing hardware 31 having an L-shaped cross section is attached to the support member 12 of the bracket 10 with bolts B and nuts N, and this rail fixing hardware 31 is By attaching and fixing the rails 30 with bolts B and nuts N, the pair of rails 30 can be spanned and fixed between the plurality of brackets 10, 10.

Specifically, as shown in FIG. 4(b), by disposing a reinforcing rail 32 between a pair of rails 30 and laying a tread member 26 on the pair of rails 30 and reinforcing rail 32, The load capacity of the landing 25 can be improved, and the safety of the landing 25 can be improved.

以上、本実施形態の壁面階段1における主要な構成について詳述したが、本実施形態の壁面階段1には、図1~図3に示すように、手摺り40が配設されることが好ましい。手摺り40の構成や設置態様は特に限定されないが、例えば、本願出願人らが先に出願し、権利化された特許第6779102号に係る手摺りが適用できる。 The main configuration of the wall staircase 1 of this embodiment has been described in detail above, but it is preferable that the wall staircase 1 of this embodiment is provided with a handrail 40, as shown in FIGS. 1 to 3. . Although the configuration and installation mode of the handrail 40 are not particularly limited, for example, the handrail according to Patent No. 6779102, which was previously filed and patented by the applicants of the present application, can be applied.

具体的には、本実施形態の壁面階段1に係るステップ20の幅方向の端部20aの外側に、ステップ20の昇降方向に沿って所定の間隔を空けて複数の支柱41を立設する。支柱41の立設方法も特に限定されないが、本実施形態では、支柱41を支柱固定金物42によってレール30の側面に固定している。そして、これら複数の支柱41間に手摺り40が配設される。支柱41と手摺り40の固定方法は特に限定されず、例えば、支柱41における所定の箇所に手摺り取付部42を配設し、手摺り取付部42に手摺り40をボルトB等で固定することができる。 Specifically, a plurality of columns 41 are erected at predetermined intervals along the ascending and descending direction of the step 20 on the outside of the widthwise end portion 20a of the step 20 of the wall staircase 1 of this embodiment. Although the method for erecting the support column 41 is not particularly limited, in this embodiment, the support support 41 is fixed to the side surface of the rail 30 using support fixing hardware 42 . A handrail 40 is arranged between the plurality of supports 41. The method of fixing the post 41 and the handrail 40 is not particularly limited, and for example, a handrail attachment part 42 is provided at a predetermined location on the post 41, and the handrail 40 is fixed to the handrail attachment part 42 with bolts B or the like. be able to.

以上の構成を備える本実施形態の壁面階段1によると、所望の勾配の階段を容易且つ安価に設置することができる。特に、本実施形態の壁面階段1においては、複数のブラケット10を所定の間隔を空けて階段状に固定し、この複数のブラケット10上に一対のレール30を架け渡し、この一対のレール30上に複数のステップ20が配設されるため、特許文献2のように、踏板部毎に一対の階段用ステップを配設する必要が無く、設置工事の簡素化や部品点数の削減、これらによる低コスト化等が図られる。 According to the wall staircase 1 of this embodiment having the above configuration, a staircase with a desired slope can be easily and inexpensively installed. In particular, in the wall staircase 1 of this embodiment, a plurality of brackets 10 are fixed at predetermined intervals in a step-like manner, and a pair of rails 30 are spanned over the plurality of brackets 10. Since a plurality of steps 20 are disposed in the stairway, there is no need to dispose a pair of stair steps for each tread part as in Patent Document 2, which simplifies the installation work, reduces the number of parts, and reduces costs. Cost reduction, etc. will be achieved.

以上、本発明の一実施形態に係る壁面階段1について詳述したが、本発明の壁面階段は上述した実施形態に限定されるものではない。例えば、上述した実施形態に係る壁面階段1は、垂直な壁面Wに複数のブラケット10を固定した態様であるが、複数のブラケット10が固定される壁面は垂直な壁面Wに限定されず、本発明の壁面階段は、壁面の角度に影響を受けることなく、所望の勾配の階段を容易且つ安価に設置することができる。 Although the wall staircase 1 according to one embodiment of the present invention has been described in detail above, the wall staircase of the present invention is not limited to the embodiment described above. For example, the wall staircase 1 according to the embodiment described above has a plurality of brackets 10 fixed to the vertical wall surface W, but the wall surface to which the plurality of brackets 10 are fixed is not limited to the vertical wall surface W, and the present invention is not limited to the vertical wall surface W. The wall staircase of the invention allows stairs with a desired slope to be easily and inexpensively installed without being affected by the angle of the wall surface.

本発明の壁面階段が設置される壁面が垂直ではない場合は、壁面の角度に応じて、本発明の壁面階段を構成するブラケット10に係る固定部材11、支持部材12及び保持部材13の連結角度を適宜調整することによって、あらゆる角度の壁面に本発明の壁面階段を設置することができる。図5(a)~(d)に示したブラケット10a~10dのように、各ブラケット10a~10dを構成する支持部材12が水平となるように、壁面の角度に応じて固定部材11と支持部材12との連結角度αを決定し、所定の連結角度αで固定部材11と支持部材12とを連結する。そして、固定部材11の他端部11bと支持部材12の他端部12bとを保持部材13で連結固定することによって、壁面の角度に応じたブラケット10a~10dを得ることができる。なお、図5(a)~(d)では、一対のレール30について、これを水平方向に配設した場合の断面で表している。 When the wall surface on which the wall staircase of the present invention is installed is not vertical, the connection angle of the fixing member 11, the supporting member 12, and the holding member 13 of the bracket 10 constituting the wall staircase of the present invention is determined according to the angle of the wall surface. By adjusting as appropriate, the wall staircase of the present invention can be installed on a wall surface at any angle. As in the brackets 10a to 10d shown in FIGS. 5(a) to 10d, the fixing member 11 and the supporting member are adjusted according to the angle of the wall surface so that the supporting member 12 constituting each bracket 10a to 10d is horizontal. 12 is determined, and the fixed member 11 and the support member 12 are connected at the predetermined connection angle α. By connecting and fixing the other end 11b of the fixing member 11 and the other end 12b of the supporting member 12 with the holding member 13, brackets 10a to 10d can be obtained that correspond to the angle of the wall surface. Note that in FIGS. 5A to 5D, the pair of rails 30 are shown in cross section when they are arranged in the horizontal direction.

本発明の壁面階段における手摺りの設置態様についても、例えば、図6及び図7に示した実施形態の壁面階段1aを構成する複数のブラケット10eは、ブラケット10eに係る支持部材12の他端部12b側に延設部12cを備え、この延設部12c上に支柱取付部44が配設されている。支柱取付部44は筒状を成しており、支柱取付部44に支柱41を挿入し、支柱取付部44に支柱41をボルトBとナットNで固定することによって、支柱41が立設されることとなる。立設された支柱41間に手摺り40を配設することによって、手摺り40を備えた本実施形態の壁面階段1aが得られる。なお、図7(a)及び図7(b)では、一対のレール30及び補強レール32について、これらを水平方向に配設した場合の断面で表している。 Regarding the installation aspect of the handrail in the wall staircase of the present invention, for example, the plurality of brackets 10e constituting the wall staircase 1a of the embodiment shown in FIGS. An extending portion 12c is provided on the 12b side, and a strut mounting portion 44 is disposed on the extending portion 12c. The strut mounting portion 44 has a cylindrical shape, and the strut 41 is erected by inserting the strut 41 into the strut mounting portion 44 and fixing the strut 41 to the strut mounting portion 44 with bolts B and nuts N. That will happen. By arranging the handrail 40 between the upright columns 41, the wall staircase 1a of the present embodiment including the handrail 40 is obtained. Note that in FIGS. 7A and 7B, the pair of rails 30 and the reinforcing rails 32 are shown in cross section when they are arranged in the horizontal direction.

また、本実施形態の壁面階段1aにおいて、壁面階段1aを構成する複数のブラケットを全てブラケット10eの態様にする必要は無く、支柱41を立設したい箇所に位置するブラケット10を、支柱取付部44を備えるブラケット10eに置き換えればよい。 In addition, in the wall staircase 1a of the present embodiment, it is not necessary to make all of the plurality of brackets constituting the wall staircase 1a into the bracket 10e. What is necessary is just to replace it with the bracket 10e equipped with.

以上、本発明の壁面階段の実施形態について詳述したが、本発明の技術的思想を実質的に限定するものと解してはならない。例えば、本発明の実施形態に係る壁面階段1,1aでは、ステップ20の配設箇所、すなわち階段部分では、図4(a)や図7(a)に示すように、一対のレール30上にステップ20を固定しているが、階段部分においても、一対のレール30間に、補強レール32が配設されてもよい。階段部分においても補強レール32を配設することによって、階段部分の耐荷重が向上され、安全性の更なる向上が図られる。本発明はその要旨を逸脱しない範囲で、当業者の創意と工夫により、適宜に改良、変更又は追加をしながら実施できる。 Although the embodiments of the wall staircase of the present invention have been described above in detail, this should not be construed as substantially limiting the technical idea of the present invention. For example, in the wall stairs 1, 1a according to the embodiment of the present invention, the step 20 is disposed at a location on the pair of rails 30, as shown in FIGS. 4(a) and 7(a). Although the step 20 is fixed, a reinforcing rail 32 may be provided between the pair of rails 30 also in the stairway portion. By arranging the reinforcing rails 32 also in the stairway portion, the load resistance of the stairway portion is improved and safety is further improved. The present invention can be implemented with appropriate improvements, changes, or additions based on the ingenuity and ingenuity of those skilled in the art without departing from the gist thereof.
