TEMPORARY STAIR AND INDOOR CONSTRUCTION METHOD OF ARCHITECTURAL STRUCTURE
To provide a temporary stair that uses a staircase substrate and can easily and safely ascent/descent upper and lower floors and leave/enter from/to a lower stair-space, and an indoor construction method of an architectural structure using the temporary stair.SOLUTION: A temporary stair 1 is formed on a staircase substrate 2 comprising a pair of parallel stringers 3 obliquely disposed thereon and a plurality of treads 4 fixed by predefined tread intervals on the stringers 3. The temporary stair 1 has the treads 4 that are not disposed across two steps or more and is disposed at a lower stair-approach port 5 formed so as to be enterable under the stair through between the stringers 3. The temporary stair 1 includes: an upper placement part 62 placed on a tread 4a at an upper side of the lower stair-approach port 5; a lower placement part 63 placed on a tread 5b at a lower side of the lower stair-approach port 5; a pair of temporary side plates 6 parallely disposed thereon; and a temporary treadboard 7 bridged between the pair of temporary side plates 6. The temporary treadboard 7 is detachably bridged over the pair of temporary side plates 6.SELECTED DRAWING: Figure 1
【課題】 階段下地を利用した仮設階段であって、上下階の昇降及び階段下空間の出入りを簡単且つ安全に行うことができる仮設階段及び当該仮設階段を利用した建築物の屋内施工方法を提供する。【解決手段】仮設階段１は、傾斜して設置される一対の平行な桁材３と、桁材３に所定の段板間隔で固定される複数の段板４とを備えた階段下地２に形成され、２段以上に亘って段板４が設けられておらず、桁材３の間を通って階段下に進入可能に形成された階段下進入口５に、設置される仮設階段１であって、階段下進入口５の上側の段板４ａに載置される上側載置部６２と、階段下進入口５の下側の段板５ｂに載置される下側載置部６３と、を備え、平行に配置される一対の仮設側板６と、一対の仮設側板６の間に架け渡される仮設踏板７と、を備え、仮設踏板７は、一対の仮設側板６に着脱自在に架け渡される。【選択図】図１
