Description

本発明は、建物に設置される階段に関する。   The present invention relates to a staircase installed in a building.

特許文献１には、桁の上面に縦断面略Ｌ字を成すステップ受けを固定して、ステップ受けに踏板を固着具で固定することが開示されている（第１の従来技術）。
また、特許文献１には、踏板の後端を桁の上面に設けたステップ受けに回動自在に軸支し、踏板の前端を下隣の踏板の上面に固定すると共に、ステップ受けは桁の上面を移動して位置調整すると共に踏板の前端は取付け高さを調整して固定することが開示されている（第２の従来技術）。 Patent Document 1 discloses that a step receiver having a substantially L-shaped longitudinal section is fixed to the upper surface of a girder, and a tread is fixed to the step receiver with a fixing tool (first prior art).
In Patent Document 1, the rear end of the tread is pivotally supported on a step receiver provided on the upper surface of the girder, and the front end of the tread is fixed to the upper surface of the lower adjacent tread. It is disclosed that the position is adjusted by moving the upper surface, and the front end of the tread is fixed by adjusting the mounting height (second prior art).

特開平９−１４４２５９号公報JP-A-9-144259

しかし、第１の従来技術では、桁の傾斜角度が変わる場合には、踏板を水平にする為にステップ受けの寸法を変える必要があり、桁の傾斜角度が変わる毎に、異なる種類のステップ受けを用意しなければならないという不都合がある。
第２の従来技術では、桁の傾斜角度が変わる場合には、一つ一つのステップ受けを桁の上面に移動して位置調整すると共に各踏板の前端の高さ調整する必要があるので、施工に手間がかかる。更に、施工手順が最下位置の踏板とステップ受けから順次上の踏板とステップ受けとを取付けることに限られているので、施工し難いという問題がある。 However, in the first prior art, when the inclination angle of the girder changes, it is necessary to change the size of the step receiver in order to level the tread, and each time the inclination angle of the girder changes, a different type of step receiver is received. There is an inconvenience that must be prepared.
In the second prior art, when the inclination angle of the girder changes, it is necessary to adjust the position by moving each step receiver to the upper surface of the girder and adjust the height of the front end of each tread. It takes time and effort. Furthermore, since the construction procedure is limited to attaching the top tread and the step receiver in order from the bottom tread and the step receiver, there is a problem that the construction is difficult.

そこで、本発明は、桁の傾斜角度が変わる場合にも同種の部材を用いて施工でき且つ施工が容易な階段の提供を目的とする。   Therefore, an object of the present invention is to provide a staircase that can be constructed using the same type of member even when the inclination angle of the girder is changed and that can be easily constructed.

請求項１に記載の発明は、桁と、ステップ受けと、踏板とを備え、桁は上面に２条の突条を長手方向に有し、２条の突条と突条間に位置する桁の上面とで嵌合溝を形成しており、ステップ受けは上端が開口する空間を内部に有しており且つ上端を所定角度で切断してあり、下端部を嵌合溝に嵌合して突条に固着具により固定してあり、踏板は下面に取付けた嵌合具を有し、嵌合具をステップ受けの上端から内部空間に嵌合してステップ受けに固着具で固定してあることを特徴とする。   The invention according to claim 1 includes a girder, a step receiver, and a tread, and the girder has two ridges in the longitudinal direction on the upper surface and is located between the two ridges and the ridge. The upper surface of the step receiver has a space in which the upper end opens, the upper end is cut at a predetermined angle, and the lower end is fitted into the fitting groove. It is fixed to the ridge with a fixing tool, and the tread has a fitting tool attached to the lower surface. The fitting tool is fitted into the inner space from the upper end of the step receiver and fixed to the step receiver with the fixing tool. It is characterized by that.

請求項１に記載の発明によれば、階段の施工は、桁を所定の角度に固定した後、ステップ受けの下端部を桁の嵌合溝に嵌めて固着具により突条に固定し、踏板の下面に取付けた嵌合具をステップ受け上端から内部空間内に嵌合してステップ受けに固着具で固定する。
桁の傾斜角度が変わる場合には、同種のステップ受けを用いて、ステップ受けを桁に固定したときに上端が水平になるように、上端を所定の角度に切断したものを用いる。したがって、本発明によれば、桁の傾斜角度が変わる場合にも、同種のステップ受けを用いて階段を施工することができる。
しかも、桁の傾斜角度が変わる場合には、上端の切断角度を変えたステップ受けを用いて桁の上面に固定すればよいので、施工現場で各踏板の傾斜を調整する作業が不要であるから、施工が容易である。
階段の施工は、最下位置の踏板から順次施工することに限られず、例えば、最上の踏板から施工することもでき、施工順序に制限がないから、施工性が良い。
また、施工現場で、ステップ受けの上端を切断して傾斜角度を調整することもできるので、施工現場での施工性が良い。
ステップ受けは、桁の嵌合溝に嵌めて位置決めした後にそのまま固着具により突条に固定できるので、ステップ受けの固定が容易にできる。
踏板は、下面取付けた嵌合具をステップ受けの内部空間内に上から嵌合するだけで位置決めでき、固定が容易にできる。 According to the first aspect of the present invention, in the construction of the staircase, after fixing the girder at a predetermined angle, the lower end portion of the step receiver is fitted into the fitting groove of the girder and fixed to the ridge by the fixing tool. The fitting member attached to the lower surface of the step is fitted into the inner space from the upper end of the step receiver and fixed to the step receiver with a fixing tool.
When the inclination angle of the girder changes, the same type of step receiver is used, and the upper end is cut at a predetermined angle so that the upper end becomes horizontal when the step receiver is fixed to the girder. Therefore, according to the present invention, a staircase can be constructed using the same type of step receiver even when the inclination angle of the girder changes.
In addition, when the inclination angle of the girder changes, it is only necessary to fix it to the upper surface of the girder using a step receiver with a changed cutting angle at the upper end, so it is not necessary to adjust the inclination of each tread on the construction site. Easy to install.
The construction of the staircase is not limited to the construction from the bottom treadle in sequence, for example, it can be constructed from the top tread, and the construction sequence is not limited, so the construction is good.
Further, since the inclination angle can be adjusted by cutting the upper end of the step receiver at the construction site, the workability at the construction site is good.
Since the step receiver can be fixed as it is to the ridge with the fixing tool after being positioned in the fitting groove of the girder, the step receiver can be easily fixed.
The tread can be positioned by simply fitting the fitting attached on the lower surface into the internal space of the step receiver from above, and can be fixed easily.
