そして、段板カバー40の凹部41をささら桁10に係合させ、段板カバー40の下面を段板支持プレート30の平面部30aの上面に当接させる。このとき、段板カバー40の下面に備えられた係合溝43a、43b及び43cは、それぞれ段板支持プレート30の立ち上がり部34a、34b及び34cに係合する。また、段板カバー40の凹部41に設けた収容部42a及び42b(図5(b)参照)によって、それぞれ段板支持プレート30の固定部32aと固定部32aに取り付けたボルト36a及び固定部32bと固定部32bに取り付けたボルト36bが収容される。
段板カバー40の固定位置が決まったら、ビスや接着剤などを用いて、段板カバー40を段板支持プレート30に固定する。
Then, the concave portion 41 of the step plate cover 40 is engaged with the further beam 10, and the lower surface of the step plate cover 40 is brought into contact with the upper surface of the flat portion 30 a of the step plate support plate 30. At this time, the engagement grooves 43 a, 43 b and 43 c provided on the lower surface of the step plate cover 40 engage with the rising portions 34 a, 34 b and 34 c of the step plate support plate 30, respectively. Also, the bolts 36a and the fixing portion 32b attached to the fixing portion 32a and the fixing portion 32a of the corrugated plate support plate 30 by the accommodating portions 42a and 42b (see FIG. 5B) provided in the concave portion 41 of the step plate cover 40, respectively. And the bolt 36b attached to the fixed portion 32b is accommodated.
When the fixing position of the corrugated board cover 40 is determined, the corrugated board cover 40 is fixed to the corrugated board support plate 30 using a screw or an adhesive.

ささら桁10に全ての段板支持プレート30及び段板カバー40を取り付けたら、最後に、図1、図2及び図7に示すように、手すり50及び手すり子51を取り付ける。   When all the corrugated plate support plates 30 and the corrugated plate cover 40 are attached to the spar 10, finally, as shown in FIGS. 1, 2, and 7, the handrail 50 and the handrail 51 are attached.

例えば、図2に示すように、一枚の段板カバー40に対して略垂直になるよう、三本の手すり子51を取り付ける。三本の手すり子51のうち、二本の手すり子51b、51bは、段板カバー40のビス穴44bに通したビス52によって、段板カバー40に固定される。残りの一本の手すり子51aは、段板カバー40の嵌合溝44aに嵌め合わされ、当該段板カバー40の下段の段板カバー40のビス穴44bに通したビス52によって下段の段板カバー40に固定される。   For example, as shown in FIG. 2, the three handrails 51 are attached so as to be substantially perpendicular to the single corrugated board cover 40. Of the three handrails 51, the two handrails 51 b and 51 b are fixed to the corrugated board cover 40 by screws 52 that pass through the screw holes 44 b of the corrugated board cover 40. The remaining one balustrade 51a is fitted in the fitting groove 44a of the step plate cover 40, and the lower step plate cover is formed by screws 52 passed through the screw holes 44b of the lower step plate cover 40 of the step plate cover 40. 40 is fixed.

以上説明した本発明のストリップ階段1によれば、段板支持プレート30が固定部32を備えているため、ストリップ階段1の設置作業における、段板支持プレート30のささら桁10への固定の際に、段板支持プレート30同士の間隔、すなわち、ストリップ階段1の段差を決めることができることとなって、ストリップ階段1の設置条件やストリップ階段1を設置する建物の利用目的などに合わせて、ストリップ階段1の段差を容易に変更することができる。
また、段板としての強度を備えた段板支持プレート30の上面及び端面を、段板としての見映えを備えた段板カバー40で覆うことによって、高い安全性と高い意匠性とを兼ね備えたストリップ階段1を提供することができる。
According to the strip staircase 1 of the present invention described above, since the step plate support plate 30 includes the fixing portion 32, the step plate support plate 30 is fixed to the spar 10 in the installation work of the strip staircase 1. In addition, it is possible to determine the interval between the step plate support plates 30, that is, the step of the strip staircase 1, so that the strip can be adapted to the installation conditions of the strip staircase 1 and the purpose of use of the building where the strip staircase 1 is installed The step of the stairs 1 can be easily changed.
Further, the upper surface and the end surface of the corrugated plate support plate 30 having the strength as the corrugated plate are covered with the corrugated plate cover 40 having the appearance as the corrugated plate, thereby combining high safety and high design. A strip staircase 1 can be provided.
