Description

この発明は、主に室内階段で、ささら桁等の側板を無くして、踏板の少なくとも一側にポールを建てて、ポールに踏板を固定した階段、この階段に使用する階段用の踏板取付金具に関する。   The present invention mainly relates to a staircase in which a side plate such as a spar girder is eliminated, a pole is built on at least one side of the tread plate, and the tread plate is fixed to the pole, and a tread plate mounting bracket for the stair used for this stair .

従来階段は、階段状に段々に配置した踏板の両端を、壁に固定して構成し(特許文献1)、あるいは斜めに架設したささら桁と称する側桁に挟んで構成していた(特許文献2)。このような階段では、住宅などの室内に設置した場合には、閉塞感があり、踏板のデザインに制約を与えていた。また、周り階段では、径200mm程度のセンターポールに踏板を支えるための支持材を螺旋状に固定して構成していたが、ポールが大径で重く、センターポールを支えるために、床側に「つか」等補強材が必要であった。   Conventionally, the staircase is constructed by fixing both ends of a step board arranged stepwise in a staircase shape to a wall (Patent Document 1), or sandwiching it between side girders called diagonally installed girders (Patent Document) 2). When such a staircase is installed in a room such as a house, there is a feeling of blockage, which restricts the design of the tread. In the surrounding staircase, the support material for supporting the tread was fixed to the center pole with a diameter of about 200 mm in a spiral shape. However, the pole is large and heavy, Reinforcing materials such as “tsuka” were necessary.

そこで、踏板をより積極的に見せるために、側桁で踏板の下面を支える提案もなされている(特許文献3)。
特開平6−294191 特開平6−32917 特開2007−146499
Then, in order to show a tread more actively, the proposal which supports the lower surface of a tread with a side girder is also made (patent document 3).
JP-A-6-294191 JP-A-6-32917 JP2007-146499A

前記従来の階段では、踏板の下面を側桁で支える構造でも1つの側桁で踏板を支えて、安全な歩行を確保するためには、側桁の断面を大きなものにせざるを得ず、階段全体の重いイメージを払拭できなかった。また、側桁を支えるために上下階の床面で側桁の上下を受けるための梁などが必要となっていた。取り分け、リフォームで階段を増設する場合には、補強が煩雑となり、採用できなかった。   In the conventional staircase, in order to secure a safe walking by supporting the step board with one side girder even if the lower surface of the tread board is supported by the side girder, the side girder must be made large in cross section. The entire heavy image could not be wiped out. Further, in order to support the side girders, beams and the like for receiving the upper and lower sides of the side girders on the floors of the upper and lower floors are necessary. In particular, when adding stairs by renovation, the reinforcement was complicated and could not be adopted.

然るにこの発明は、ささら桁などの側桁を無くして、階段の端面を縦に配置したポールに固定したので、前記問題点を解決した。   However, the present invention solves the above-mentioned problems because the side girders such as the spar girders are eliminated and the end faces of the stairs are fixed to the poles arranged vertically.

(4) 前記ポール間に前記踏板の端面を臨ませ、前記踏板の端面と前記ポールとを踏板取付金具を介して固定する。
(5) 前記踏板取付金具は、前記踏板の幅方向の端縁部下面を支持できる水平方向の支持板と、階段進行方向の両端部に、前記踏板の端面に当接する固定板を連設して構成する。前記固定板の幅を前記ポールの外径以下とし、前記固定板を前記ポールに固定し、前記両固定板間に、取付予定の踏板の端面を臨むことができる開口を形成する。 前記支持板と前記踏板下面とを固定する。
That is, the present invention is a staircase characterized in that it is configured as follows.
(1) The treads are arranged in a staircase shape, and the end surfaces in the step width direction of the treads are defined as one end surface and the other end surface.
(2) The one end face is connected to a pole arranged in parallel in the vertical direction, and the other end face is fixed to a pole or wall face arranged in parallel in the vertical direction.
(3) The nose side of the end surface of the upper floor tread and the kick side of the end surface of the lower floor tread are fixed to the one pole.
(4) The end surface of the tread is exposed between the poles, and the end surface of the tread is fixed to the pole via a tread mounting bracket .
(5) The tread plate mounting bracket includes a horizontal support plate that can support the lower surface of the end edge portion in the width direction of the tread plate, and a fixed plate that contacts the end surface of the tread plate at both ends in the staircase traveling direction. Configure. The width of the fixed plate is set to be equal to or smaller than the outer diameter of the pole, the fixed plate is fixed to the pole, and an opening is formed between the fixed plates so that the end surface of the tread plate to be attached can be faced. The support plate and the tread plate lower surface are fixed.

また、他の発明は、階段状に配置した踏板の端面を、縦に配置したポールで固定する為の金具であって、以下のように構成したことを特徴とする階段用の踏板取付金具である。
(1) 踏板の幅方向の端縁部下面を支持できる水平方向の支持板で、階段進行方向の両端部に、前記踏板の端面に当接する固定板を連設する。
(2) 前記固定板の幅を前記ポールの外径以下とし、前記固定板に前記ポールと固定する為の固定手段を形成する。
(3) 前記両固定板間に、取付予定の踏板の端面を臨むことができる開口を形成する。
(4) 前記支持板に踏板下面との取付手段を形成する。
Further, another invention is a metal fitting for fixing the end face of a step board arranged in a staircase shape with a pole arranged in a vertical direction, which is constructed as follows. is there.
(1) A horizontal support plate that can support the lower surface of the edge portion in the width direction of the tread plate, and a fixed plate that contacts the end surface of the tread plate is provided at both ends in the staircase traveling direction.
(2) The fixing plate has a width equal to or less than the outer diameter of the pole, and a fixing means for fixing the pole to the pole is formed on the fixing plate.
(3) An opening capable of facing the end surface of the treadle to be attached is formed between the fixed plates.
(4) Forming means for attaching the lower surface of the tread plate to the support plate .

前記におけるポールは、主に丸パイプ(中空材料)であるが、角パイプ、丸棒(中実材料)、角棒など同等の断面構造の材料を使用することもできる。   The pole in the above is mainly a round pipe (hollow material), but a material having an equivalent cross-sectional structure such as a square pipe, a round bar (solid material), a square bar, etc. can also be used.

また、前記における「目視されない」は物理的に隠れて見えない場合や、位置関係により見えにくい場合を含む。   In addition, “not visually recognized” in the above includes cases where it is physically hidden and cannot be seen, and cases where it is difficult to see due to the positional relationship.

この発明の階段では、踏板の一端面をポール、他端面を壁又はポールで固定したので、側桁を不要とし、ポール側、ポールの間から踏板の端面を臨むことができるので、踏板の特徴を表した階段のデザインの幅を広げることができる。また、側桁を使用せずに、ポールで支持するので、使用する部材の重量が極めて軽く、組み立て用の足場も不要とし、作業効率・安全性を高め、1人の作業でも組立を可能とする効果がある。   In the stairs of the present invention, since one end face of the tread is fixed with a pole and the other end face is fixed with a wall or a pole, the side girders are unnecessary, and the end face of the tread can be seen from between the pole and the pole. The width of the staircase design can be expanded. In addition, because it is supported by a pole without using side girders, the weight of the components used is extremely light, no scaffolding for assembly is required, and work efficiency and safety are improved, enabling assembly by one person. There is an effect to.

また、ポールで踏板の一端面又は他端面を支持するので、重い側桁(60〜80kg程度)を不要にできる。例えば、階段幅や踏板の材質や構造にもよるが、1本のポールが負担する荷重は6kg程度となり、1本のポールと床が負担する荷重を分散できる。従って、ポールの下面での補強を不要にし、階段の構築作業を簡略化できる。従って、とりわけリフォームで階段を新たに構築する場合には、有効である。   Moreover, since one end surface or the other end surface of the tread is supported by the pole, a heavy side beam (about 60 to 80 kg) can be eliminated. For example, although depending on the width of the stairs and the material and structure of the tread, the load borne by one pole is about 6 kg, and the load borne by one pole and the floor can be dispersed. Therefore, it is not necessary to reinforce the lower surface of the pole, and the construction work of the stairs can be simplified. Therefore, it is effective particularly when a staircase is newly constructed by renovation.

また、ポール床受け具を使用した場合には、現場でのポールの芯出しを不要とし。さらにポールの並列作業を簡略化し、階段組立作業を効率化できる。   Also, when using a pole floor holder, there is no need to center the pole on site. Furthermore, the parallel work of poles can be simplified and the stair assembly work can be made more efficient.

ここで、踏板22は、取付金具1、15の透孔6、17に一致するように、予め取付穴(非貫通)26、26を空けてある(図1)。   Here, the tread plate 22 is provided with mounting holes (non-penetrating) 26 and 26 in advance so as to coincide with the through holes 6 and 17 of the mounting brackets 1 and 15 (FIG. 1).

また、ポール28は、取付金具1、15のビス孔10、19の位置に応じて、パイプナットを取り付けて、ねじ孔29、29を形成してあるので、取付金具1との固定に溶接を不要にできる(図1、図3)。尚、ねじ孔29の形成はパイプナットによらず、直接に加工しあるいは他の方法によることもできる(図示していない)。また、緩み防止ができれば、ねじ孔29に代えて、ピン孔とすることもできる(図示していない)。   In addition, the pole 28 is formed with screw nuts 29 and 29 by attaching pipe nuts according to the positions of the screw holes 10 and 19 of the mounting brackets 1 and 15, so that welding is performed for fixing to the mounting bracket 1. It can be made unnecessary (FIGS. 1 and 3). Note that the screw hole 29 can be formed directly or by other methods (not shown) without using a pipe nut. Further, if the loosening can be prevented, a pin hole can be used instead of the screw hole 29 (not shown).

また、ポール床受け具31は、短冊状のベース板32の上面32aに、ポール28の並列間隔に応じて、ポール28の中空側に嵌挿できる突起(ポール固定手段)33、33を形成してある(図8)。尚、ポール床受け金具31は、1つベース板32に1つの突起33を形成した1つのポール用に構成することもできる(図示していない)。   Further, the pole floor holder 31 has protrusions (pole fixing means) 33 and 33 that can be fitted into the hollow side of the pole 28 on the upper surface 32a of the strip-shaped base plate 32 according to the parallel interval of the poles 28. (FIG. 8). The pole floor support 31 can be configured for one pole in which one protrusion 33 is formed on one base plate 32 (not shown).

(1) ポール設置位置で、下階床35にポール床受け具31を固定する。この際、ポール床受け具31は下階床35に直接に固定しても良いが(図6)、ベース板32を納める凹部36を形成し、下階床35面とポール床受け具31のベース板32上面32aとが面一になるようにすることもできる(図8)。この状態で、下階床35面上には、ポール28、28の設置間隔に応じて突起33、33が並んだ構成となっている(図8)。 (1) The pole floor support 31 is fixed to the lower floor 35 at the pole installation position. At this time, the pole floor support 31 may be fixed directly to the lower floor 35 (FIG. 6), but a recess 36 for receiving the base plate 32 is formed, and the surface of the lower floor 35 and the pole floor support 31 are formed. The base plate 32 may be flush with the upper surface 32a (FIG. 8). In this state, the projections 33 and 33 are arranged on the surface of the lower floor 35 according to the installation interval of the poles 28 and 28 (FIG. 8).

(2) 続いて、並べたポール28、28間に取付金具1、1を固定する(図8)。この際、ポール29の側面に固定板7、7を当てて、固定板7のビス孔10に大径部11側からビス51をポール28のねじ孔29に向かって打ち、固定板7をポール28に固定する(図1、図3)。この際、ビスの頭部は大径部11内に収容されるので、固定板7の面9にビス51が突出することはない。また、並列したポール28、28の内、両端に位置するポール28を除く中間位置のポール28には、1本のポール28に対して、上側の段の取付金具1の固定板7と下側の段の取付金具1の固定板7が夫々固定される。この状態で、各ポール28、28は、取付金具1、1を介して連結され、取り扱いが容易となる(図8)。
次ぎに、取付金具1、1で連結されたポール28、28を、ポール床取付具31に固定する(図8)。この際、ポール28下端の中空部30に、ポール床取付具31の突起33を差し込むだけで、容易に作業ができる。
(2) Subsequently, the mounting brackets 1 and 1 are fixed between the arranged poles 28 and 28 (FIG. 8). At this time, the fixing plates 7, 7 are applied to the side surfaces of the pole 29, the screws 51 are driven into the screw holes 10 of the fixing plate 7 from the large diameter portion 11 side toward the screw holes 29 of the poles 28, and the fixing plate 7 is It fixes to 28 (FIG. 1, FIG. 3). At this time, since the screw head is housed in the large diameter portion 11, the screw 51 does not protrude from the surface 9 of the fixing plate 7. Further, among the parallel poles 28, 28, the pole 28 in the middle position excluding the poles 28 located at both ends is connected to the fixing plate 7 and the lower side of the upper mounting bracket 1 with respect to one pole 28. The fixing plates 7 of the mounting bracket 1 in the step are respectively fixed. In this state, the poles 28 and 28 are connected via the mounting brackets 1 and 1 so that the handling becomes easy (FIG. 8).
Next, the poles 28 and 28 connected by the mounting brackets 1 and 1 are fixed to the pole floor mounting tool 31 (FIG. 8). At this time, simply inserting the projection 33 of the pole floor fixture 31 into the hollow portion 30 at the lower end of the pole 28 enables easy operation.

尚、ポール28、28に取付金具1、1を固定する作業は、取付金具1、1の位置を予め墨出ししたポール28、28を1本づつポール床受け金具31の突起33に差し込んで、ポール28、28を並列して取り付けた後に、2本のポール28、28間に取付金具1、1を取り付けることもできる(図示していない)。   The work of fixing the mounting brackets 1, 1 to the poles 28, 28 is performed by inserting the poles 28, 28 in which the positions of the mounting brackets 1, 1 are preliminarily inserted into the protrusions 33 of the pole floor support bracket 31 one by one. After the poles 28 and 28 are attached in parallel, the mounting brackets 1 and 1 can be attached between the two poles 28 and 28 (not shown).

(3) (1)(2)の工程の後に、または前に、または同時に、壁44の踏板設置位置に応じて、壁44に墨出しをして、壁44に、取付金具15、15を固定する。この際、取付金具15の固定板18を壁44に付け、ビス孔19からビス(ねじ)52を打ち込み固定する(図1、図2)。取付金具1と同様に、ビス(ねじ)52の頭部は大径部20に収容され、固定板18の表面から突出しない。 (3) (1) After, before, or simultaneously with the step (2), the wall 44 is marked according to the position of the tread plate installed on the wall 44, and the mounting brackets 15, 15 are attached to the wall 44. Fix it. At this time, the fixing plate 18 of the mounting bracket 15 is attached to the wall 44, and a screw (screw) 52 is driven and fixed from the screw hole 19 (FIGS. 1 and 2). Similar to the mounting bracket 1, the head of the screw (screw) 52 is accommodated in the large diameter portion 20 and does not protrude from the surface of the fixing plate 18.

(4) 以上の作業が完了した状態で、1つの踏板22を取り付けるための取付金具1、15が、向かい合って壁44とポール22側に夫々配置された状態になっている(図9(a))。 (4) With the above operations completed, the mounting brackets 1 and 15 for mounting one tread 22 are arranged facing each other on the side of the wall 44 and the pole 22 (FIG. 9A). )).

(5) 続いて、ポール22側、壁44側の取付家具1、15の支持板2、16上に、踏板22の幅W方向の両端24、24a側を載せる(図1、図9(b))。この状態で、固定板7の面9は、踏板22の端面24が当接して塞がれる。この状態で、取付金具1、15の透孔6、17から(下方から上に向けて)ボルト46を打ち込み、踏板22を取付金具1、15(支持板2、16)に固定する(図9(c))。従って、踏板22を取り付けた後に、振動などによりビス51が緩むおそれが無く、また、例えビスが緩んだ場合であっても塞がれているので、ビスが固定板7、18から外れるおそれが無い。
この際、下の段から踏板22を取り付ければ、取り付けた踏板22を作業足場として利用して、上段側の踏板22、22の取付作業ができる。また、踏板22の取付作業は下の段からのみならず上の段からあるいは、中間の段から、更には複数の位置から同時に取付作業をすることもできる。
(5) Subsequently, the pole 22 side, on the support plate 2, 16 for mounting furniture 1,15 wall 44 side, placing the ends 24,24a side of the width W 0 direction of step board 22 (FIG. 1, FIG. 9 ( b)). In this state, the surface 9 of the fixed plate 7 is blocked by the end surface 24 of the tread plate 22 coming into contact therewith. In this state, bolts 46 are driven through the through holes 6 and 17 of the mounting brackets 1 and 15 (from bottom to top) to fix the tread 22 to the mounting brackets 1 and 15 (support plates 2 and 16) (FIG. 9). (C)). Therefore, after the tread plate 22 is attached, there is no possibility that the screw 51 is loosened due to vibration or the like, and even if the screw is loosened, the screw 51 is blocked, so that the screw may come off from the fixing plates 7 and 18. No.
At this time, if the tread 22 is attached from the lower stage, the attaching work of the upper treads 22 and 22 can be performed using the attached tread 22 as a work scaffold. The tread plate 22 can be attached not only from the lower stage but also from the upper stage, from the intermediate stage, or from a plurality of positions at the same time.

(6) また、この際、両取付金具1、15の固定板7、18間の距離Lが、踏板22の幅Wに比較して、長い場合には(図1(b))、踏板22の端面24をポール28側に寄せて、踏板22の端面24を固定板7、7に当接した状態で、踏板22の端面24aと固定板18との間に楔48、48を打ち込んで隙間を調節する(図2)。この際、壁44側の取付金具15の透孔17を長孔に形成してあるので、支持板16と踏板22とが相対的に幅W方向でずれた場合であっても、楔48、48の数と大きさを調節すれば、取付に支障は無い(図2(b)(c))。尚、楔48を使用sれば、踏板22の端面24又は楔48でビス51、52の頭を押すことになるので、ビス51、52の緩み防止に役立つ。 (6) At this time, if the distance L between the fixing plates 7 and 18 of the mounting brackets 1 and 15 is longer than the width W 0 of the tread plate 22 (FIG. 1B), the tread plate With the end surface 24 of the tread plate 22 close to the pole 28 and the end surface 24 of the tread plate 22 in contact with the fixing plates 7 and 7, wedges 48 and 48 are driven between the end surface 24 a of the tread plate 22 and the fixing plate 18. Adjust the gap (Figure 2). At this time, since the through-hole 17 of the mounting bracket 15 on the wall 44 side is formed as a long hole, the wedge 48 even if the support plate 16 and the tread plate 22 are relatively displaced in the width W 0 direction. If the number and size of 48 are adjusted, there is no hindrance to the mounting (FIGS. 2B and 2C). If the wedge 48 is used, the heads of the screws 51 and 52 are pushed by the end surface 24 of the tread plate 22 or the wedge 48, which helps to prevent the screws 51 and 52 from loosening.

また、予め両取付金具1、15の固定板7、18間の距離Lを、踏板22の幅Wと同等(同一又は若干大きい)に形成すれば、楔48、48や楔48を隠すための仕上げ処理が不要となる。この場合であっても、踏板22の端面24、24aがビス51、52の頭部を保護するので、歩行の衝撃によっては、ビス51、52が緩みを防止できる。 Further, if the distance L between the fixing plates 7 and 18 of the mounting brackets 1 and 15 is previously formed to be equal to (same or slightly larger) the width W 0 of the tread plate 22, the wedges 48 and 48 and the wedge 48 are hidden. No finishing process is required. Even in this case, since the end surfaces 24 and 24a of the tread plate 22 protect the heads of the screws 51 and 52, the screws 51 and 52 can be prevented from loosening depending on the impact of walking.

(7) 以上のようにして、総ての踏板22、22の取付が完了して、下階床35と上階床38との間に階段40を構築する(図6)。また、壁44側の端縁は、楔48、48などを隠すように、適宜カバーなどで覆うこともできる(図示していない)。図6で、41はポール28、28の上端を連結し、かつ壁44に支持した振れ止め具である。また、42は上階の腰壁、43は天井である。 (7) As described above, the attachment of all the treads 22, 22 is completed, and the staircase 40 is constructed between the lower floor 35 and the upper floor 38 (FIG. 6). Further, the edge on the wall 44 side can be covered with a cover or the like as appropriate so as to hide the wedges 48 and 48 (not shown). In FIG. 6, reference numeral 41 denotes a steady rest that connects the upper ends of the poles 28 and 28 and is supported by the wall 44. Further, 42 is a waist wall on the upper floor, and 43 is a ceiling.

(8) このように構築した階段40では、ポール28側で、ポール28、28間で、取付金具1の開口12から踏板22の端面24が見え、かつ取付金具1は目視できないので、踏板22の木目などの模様を生かした階段を構築できる(図1(c))。ここで、切欠5を設けたので、端縁5aは、踏板22の端面24からLだけ奥に位置するので、目視できないに等しい。 (8) In the staircase 40 constructed in this way, on the pole 28 side, the end surface 24 of the tread 22 can be seen from the opening 12 of the mounting bracket 1 between the poles 28 and 28, and the mounting bracket 1 cannot be seen. Stairs that make use of patterns such as wood grain can be constructed (FIG. 1C). Here, since there is provided a notch 5, the edges 5a, so positioned on the back from the end surface 24 of step board 22 by L 2, equal to not be visible.

また、構築作業において、作業者は、ポール28又は連結したポール28、28、踏板22の一枚ずつ、ポール床受け具31等軽量な部材のみを使用し、順番に組み立てるだけで階段40を構築できるので、少人数例えば1人であっても階段40の構築作業を行うことができる。   Further, in the construction work, the worker constructs the stairs 40 by using only light members such as the pole floor support 31 for each of the poles 28 or the connected poles 28 and 28 and the tread plate 22 and assembling them in order. Therefore, the construction work of the stairs 40 can be performed even by a small number of people, for example, one person.

(9)他の実施例 (9) Other embodiments

前記実施例において、壁44側の取付金具15を使用したが、壁44側にも取付金具1を使用することもできる(図示していない)。   In the above embodiment, the mounting bracket 15 on the wall 44 side is used, but the mounting bracket 1 can also be used on the wall 44 side (not shown).

また、前記実施例において、踏板22の一端24aを壁44に取り付けたが、踏板22の両端面24、24aをポール28、28で固定する構造とすることもできる(図7参照)。この場合には、取付金具は、ポール用の取付金具1、1のみを使用する。踏板22の端縁24、24aで取付金具1は同一のものを使用するが、一方の取付金具1の透孔6を取付金具15の透孔17のような長孔とすることもできる(図示していない)。   In the above embodiment, one end 24a of the tread plate 22 is attached to the wall 44. However, both end surfaces 24, 24a of the tread plate 22 may be fixed by poles 28, 28 (see FIG. 7). In this case, only the mounting brackets 1 and 1 for the pole are used as mounting brackets. Although the same mounting bracket 1 is used for the edges 24 and 24a of the tread plate 22, the through hole 6 of one mounting bracket 1 can be a long hole such as the through hole 17 of the mounting bracket 15 (see FIG. Not shown).

また、前記実施例において、下階床35から上階床38まで直進する階段について説明したが、周り階段を組合せた構造、あるいは周り階段のみの構造の階段とすることもできる(図7参照)。この場合にも同様に、上下に位置する踏板22、22aの間に配置したポール28に踏板22を固定する。従って、平面形状が長方形にはならない踏板22aの場合には応じ形状で、取付金具1の支持板2の形状を変え、また支持板2での固定板7、7の取付位置を応じて変える(図示していない)。
この場合、一般的にはポール28、28の取付間隔を一定することが意匠上好ましいので、直向部分の踏板22の間隔と同一の間隔で周り階段部分のポール28、28の間隔とする(図7)。従って、踏板22a部分では、端面で少なくとも2箇所にポール28、28位置するように形成される。従って、踏板22a用の取付金具1の構造も、踏板22aの平面形状に応じた支持板2、ポール28の位置に応じて、固定板7、7を取り付けた構造とする(図示していない)。
Moreover, in the said Example, although the staircase which goes straight from the lower floor 35 to the upper floor 38 was demonstrated, it can also be set as the staircase of the structure which combined the surrounding staircase, or the structure of only a surrounding staircase (refer FIG. 7). . In this case as well, the tread 22 is fixed to a pole 28 disposed between the treads 22 and 22a positioned above and below. Therefore, in the case of the tread 22a whose planar shape is not rectangular, the shape is changed according to the shape, and the shape of the support plate 2 of the mounting bracket 1 is changed, and the mounting positions of the fixing plates 7 and 7 on the support plate 2 are changed ( Not shown).
In this case, it is generally preferable in design that the mounting interval between the poles 28 and 28 is constant, so that the interval between the poles 28 and 28 in the surrounding staircase portion is the same as the interval between the treads 22 in the direct direction portion ( FIG. 7). Accordingly, the tread 22a is formed so that the poles 28 and 28 are located at at least two places on the end face. Therefore, the structure of the mounting bracket 1 for the tread 22a is also a structure in which the fixing plates 7 and 7 are attached according to the positions of the support plate 2 and the pole 28 according to the planar shape of the tread 22a (not shown). .

また、前記実施例において、ポール床受け具31で、ポール固定手段として、ポール28の中空部に入る突起33としたが、ポール28を挿入できる筒体や凹部からポール固定手段を形成することもできる(図示していない)。   In the above-described embodiment, the pole floor support 31 has the protrusion 33 that enters the hollow portion of the pole 28 as the pole fixing means. However, the pole fixing means may be formed from a cylindrical body or a recess into which the pole 28 can be inserted. Yes (not shown).

また、前記実施例において、取付金具1の切欠5を形成したので、端縁5aが奥に位置して目視し難いが、踏板22の下面に、取付金具1の支持板2を収容する凹部を形成することもできる(図示していない)。この場合、切欠5の端縁5aは完全に隠れるので、目視できない。   Further, in the embodiment, since the notch 5 of the mounting bracket 1 is formed, the edge 5a is located at the back and is difficult to see, but a recess for accommodating the support plate 2 of the mounting bracket 1 is formed on the lower surface of the tread plate 22. It can also be formed (not shown). In this case, the edge 5a of the notch 5 is completely hidden and cannot be visually observed.

また、前記実施例において、振れ止め具41を使用したが、天井43でポール28、28の上端を支持することもできる(図示していない)。また、ポール床受け具31を使用せずに、直接下階の床35にポール28、28の下端を固定することもできる(図示していない)。   In the above embodiment, the steady rest 41 is used, but the upper ends of the poles 28 and 28 can be supported by the ceiling 43 (not shown). Further, the lower ends of the poles 28 and 28 can be directly fixed to the floor 35 on the lower floor without using the pole floor support 31 (not shown).
