CONSTRUCTION METHOD OF FIREPROOF WALL
To provide a construction method of a fireproof wall capable of executing construction work of a fireproof wall for a vertical hole section extending over a plurality of floors around an elevator shaft in parallel with building skeleton construction and improving safety at the time of construction.SOLUTION: A method for constructing a fireproof wall forming a vertical hole section around an opening part 12 for an elevator shaft 11 for each of a plurality of construction sections A including a plurality of layers provides with a step for assembling a column 5 and a beam 3 provided around the opening part 12 in the construction section A; a step for covering the opening part 12 with a temporary floor slab 7 in the lowermost layer of the construction section A; a step for assembling a temporary scaffold 9 reaching the upper part of the construction section A on the temporary floor slab 7, and a step for forming a fireproof wall 2 around the elevator shaft 11 by using the temporary scaffold 9.SELECTED DRAWING: Figure 4
【課題】エレベータシャフト周りにおける複数階に亘る竪穴区画用耐火壁の構築工事を、建物躯体工事と並行して行うことが可能で、かつ、施工時の安全性の向上を図ることが可能な耐火壁の構築方法を提案する。【解決手段】複数の階層を含む工区Ａ毎にエレベータシャフト１１用の開口部１２の周囲に竪穴区画を形成する耐火壁の構築方法であって、工区Ａ内の開口部１２の周囲に設けられる柱５および梁３を組み立てる工程と、工区Ａの最下層において開口部１２を仮設床スラブ７で覆う工程と、仮設床スラブ７上に工区Ａの上部に至る仮設足場９を組み立てる工程と、仮設足場９を利用して、エレベータシャフト１１の周囲に耐火壁２を形成する工程とを備えている。【選択図】図４
