しかし、特許文献１の手摺付き階段では、支柱が踏板を支持する構成になっているので、支柱は各踏板に設けることに限られると共に階段の左右両側に手摺を設けることに限られており、階段の片側にだけ手摺を設けたり、必要に応じて手摺を後付けすることができないという問題がある。 However, in the staircase with a handrail of Patent Document 1, since the support column is configured to support the tread plate, the support column is limited to being provided on each tread plate and is limited to providing handrails on the left and right sides of the staircase, There is a problem that a handrail cannot be provided only on one side of the staircase, or a handrail cannot be retrofitted as necessary.

そこで、本発明は、支柱を階段の任意の踏板に取付けできると共に必要に応じて後付けができる手摺付き階段の提供を目的とする。 Then, this invention aims at provision of the staircase with a handrail which can attach a support | pillar to the arbitrary treads of a staircase and can be retrofitted as needed.

請求項１に記載の発明は、踏板と、支柱と、手摺とを備え、支柱は下端を任意の一の踏板の上面に固定してあり、上端と下端との間に位置する中間部を一の踏板の上隣に位置する他の踏板に固定してあり、手摺は各支柱の上端間に架設してあることを特徴とする。 The invention according to claim 1 includes a step board, a support column, and a handrail, and the support column has a lower end fixed to the upper surface of an arbitrary one of the step plates, and an intermediate portion located between the upper end and the lower end. It is fixed to the other treads located on the next to the treads, and the handrail is constructed between the upper ends of the respective columns.

請求項１に記載の発明によれば、支柱は、任意の一の踏板と一の踏み板の上隣に位置する他の踏板とに固定してあるから、支柱は任意の踏板に立設できると共に階段の片側や両側にも取付けでき、且つ必要に応じて後付けができる。
また、支柱は一の踏み板の上面に固定するから、踏板から食み出さないので外観が良い。
支柱は一の踏板と上隣の他の踏み板との上下２箇所で固定するから安定に固定でき、支柱間に補強材を架設しなくても済むので、部品点数を少なくできると共に施工が簡易である。 According to the first aspect of the present invention, since the column is fixed to any one step plate and another step plate located adjacent to the one step plate, the column can be erected on any step plate. It can be attached to one or both sides of the staircase, and can be retrofitted as needed.
In addition, since the column is fixed to the upper surface of one of the treads, it does not protrude from the treads, so the appearance is good.
The struts are fixed at two locations, one on the top and the other on the top, so that they can be fixed stably, and there is no need to install a reinforcing material between the struts. is there.

次に、本実施の形態にかかる手摺付き階段１の施工、作用効果について説明する。
手摺付き階段の施工は、桁３、３を所定の角度にして、床２０と階上の躯体２２とに固定した後、ステップ受け５の下端部５ｃを桁３の嵌合溝１１に嵌めて固着具８により突条９に固定する。尚、ステップ受け５の上端５ａは桁３の傾斜角度に応じて所定角度Ｓで予め切断しておく。
次に、踏板７の下面７ｂに嵌合具１３取付け、嵌合具１３をステップ受け５の上端から内部空間１４内に嵌合して、ステップ受け５の両側面５ｂ、５ｂに固着具１７で固定する。
尚、桁３の傾斜角度Ｓが異なる階段を施工する場合には、同種のステップ受け５を用いて、ステップ受け５を桁３に固定したときに上端５ａが水平になるように上端５ａを所定の角度に切断して用いる。
支柱２１の立設は、任意の一の踏板７ｍの上面に下端固定具２５の下部をねじ固定し、支柱２１の下端２１ａから支柱２１の中空内に下端固定具２５を嵌め入れた後、支柱２１の裏側から下端固定具２５の上部２５ｂに支柱２１をねじで固定する。次に、一の踏板７ｍの上隣に位置する他の踏板７ｎの前端下面と支柱２１の中間部２１ｃとに中間固定具２９を配置して、中間固定具２９の一側部２９ａを支柱２１の裏面にねじ固定し、他側部２９ｂを踏板７ｎの前端下面にねじ固定する。
図３に示すように、手摺２３は支柱２１の上端に上方から基板２３ａをねじ固定した後、基板２３ａに本体２３ｂをねじ固定して取付ける（図３参照）。 Next, construction and effects of the staircase 1 with a handrail according to the present embodiment will be described.
For the construction of the stairs with handrails, the girders 3 and 3 are fixed at a predetermined angle and fixed to the floor 20 and the upper frame 22, and then the lower end portion 5 c of the step receiver 5 is fitted into the fitting groove 11 of the girder 3. It fixes to the protrusion 9 with the fixing tool 8. FIG. The upper end 5a of the step receiver 5 is cut in advance at a predetermined angle S according to the inclination angle of the beam 3.
Next, the fitting tool 13 is attached to the lower surface 7b of the tread board 7, the fitting tool 13 is fitted into the internal space 14 from the upper end of the step receiver 5, and the fixing tool 17 is attached to both side surfaces 5b and 5b of the step receiver 5. Fix it.
In addition, when constructing stairs where the inclination angle S of the girder 3 is different, the upper end 5a is predetermined so that the upper end 5a becomes horizontal when the step receiver 5 is fixed to the girder 3 using the same type of step receiver 5. Cut at an angle of
The column 21 is erected by screwing the lower part of the lower end fixture 25 onto the upper surface of any one tread 7m and fitting the lower end fixture 25 into the hollow of the column 21 from the lower end 21a of the column 21. The column 21 is fixed to the upper portion 25b of the lower end fixture 25 from the back side of the screw 21 with screws. Next, the intermediate fixing tool 29 is disposed on the lower surface of the front end of the other step board 7n positioned adjacent to the upper side of the one step board 7m and the intermediate portion 21c of the support column 21, and one side portion 29a of the intermediate fixing device 29 is connected to the support column 21. The other side portion 29b is screwed to the lower surface of the front end of the tread plate 7n.
As shown in FIG. 3, the handrail 23 is attached to the upper end of the column 21 by screwing the substrate 23a from above, and then fixing the main body 23b to the substrate 23a by screwing (see FIG. 3).

本実施の形態によれば、支柱２１は、任意の一の踏板７ｍと一の踏み板の上隣に位置する他の踏板７ｎとに固定してあるから、支柱２１は任意の踏板に立設できると共に階段１の片側や両側にも任意に取付けでき、且つ必要に応じて後付けができる。
また、支柱２１は一の踏み板の上面７ｍに固定するから、踏板７の外に食み出さず外観が良い。
支柱２１は一の踏板７ｍと上隣の他の踏み板７ｎとの上下２箇所で固定するから安定に固定でき、支柱２１、２１間に補強材を架設しなくて済むので、部品点数を少なくできると共に施工が簡易である。
支柱２１の下端固定具２５を中空内に収めているので、下端固定具２５が外から見えず外観が良い。
中間固定具２９は支柱２１の裏側と踏板７ｎの下面とに固定しており、階段１の正面から見えないので外観が良い。
ステップ受け５は上端５ａが所定の角度に切断自在であるから、桁３の傾斜角度が異なる場合にも、同種のステップ受け５を用いて手摺付き階段１を施工することができる。
ステップ受け５は、桁３の嵌合溝１１に嵌めて、固着具８により突条９に固定するので、位置決めした後にそのまま突条９に固定でき、ステップ受け５の固定が容易にできる。
踏板７は、下面７ｂに取付けた嵌合具１３をステップ受け５の内部空間１４内に上端から嵌合してステップ受け５の側壁５ｂに固着具１７で固定するので、固定が容易にできる。
突条９の側面にある開口を目板１２により塞がれているので、ステップ受けを突条９に固定している固着具８が外側から見えず、外観が良い。 According to the present embodiment, the column 21 is fixed to any one tread 7m and the other tread 7n positioned adjacent to the one tread, so that the column 21 can stand on any tread. At the same time, it can be arbitrarily attached to one side or both sides of the stairs 1, and can be retrofitted as necessary.
Further, since the support column 21 is fixed to the upper surface 7m of one footboard, the appearance does not protrude outside the footboard 7 and the appearance is good.
Since the support column 21 is fixed at two upper and lower positions of one step plate 7m and the other adjacent step plate 7n, it can be fixed stably, and it is not necessary to install a reinforcing material between the support columns 21 and 21, so the number of parts can be reduced. And construction is simple.
Since the lower end fixture 25 of the column 21 is housed in the hollow, the lower end fixture 25 is not visible from the outside, and the appearance is good.
The intermediate fixing tool 29 is fixed to the back side of the support column 21 and the lower surface of the tread board 7n and is not visible from the front of the stairs 1, so that the appearance is good.
Since the upper end 5a of the step receiver 5 can be cut at a predetermined angle, the step 1 with a handrail can be constructed using the same type of step receiver 5 even when the inclination angle of the beam 3 is different.
Since the step receiver 5 is fitted in the fitting groove 11 of the beam 3 and fixed to the protrusion 9 by the fixing tool 8, it can be fixed to the protrusion 9 as it is after positioning, and the step receiver 5 can be easily fixed.
The tread plate 7 is easily fixed because the fitting 13 attached to the lower surface 7b is fitted into the inner space 14 of the step receiver 5 from the upper end and fixed to the side wall 5b of the step receiver 5 with the fixing tool 17.
Since the opening on the side surface of the ridge 9 is closed by the eye plate 12, the fixing tool 8 fixing the step receiver to the ridge 9 cannot be seen from the outside, and the appearance is good.

本発明は、上述した実施の形態に限らず、本発明の要旨を逸脱しない範囲で種々変形可能である。
例えば、支柱２１は下端固定具２５や中間固定具２９を用いずに直接ねじ等で固定するものであっても良い。
