METHOD OF CONSTRUCTING REINFORCEMENT SLAB
PROBLEM TO BE SOLVED: To provide a method of constructing a reinforcement slab that can easily form a gap between an upper surface of a slab of an existing structure and the reinforcement slab.SOLUTION: There is provided a method of constructing a reinforcement slab in which a reinforcement slab 2 is provided leaving a gap ST with an upper surface 3a of a ceiling slab 3. This method includes: an arranging process of arranging a tubular body 12 capable of forming a closed space SC1 increasing in height as a fluid is supplied on the side of the upper surface 3a of the ceiling slab 3; a casting process of casting the reinforcement slab 2 on the side of the upper surface 3a of the ceiling slab 3 and above the tubular body 12 after the arranging process; a fluid supply process of elevating the reinforcement slab 2 by the closed space SC1 by supplying air to the closed space SC1 formed of the tubular body 12 after the casting process; and a support member forming process of providing reinforcement slab support members 8, 9 between the ceiling slab 3 and reinforcement slab 2 while the reinforcement slab 2 is elevated in the fluid supply process.
【課題】既設構造物のスラブの上面と補強スラブとの間の隙間を容易に形成することができる補強スラブの施工方法を提供する。【解決手段】天井スラブ３の上面３ａとの間に隙間ＳＴを空けて補強スラブ２を設ける補強スラブの施工方法である。この方法は、天井スラブ３の上面３ａ側に、流体の供給によって高さが高くなる閉鎖空間ＳＣ１を形成可能な管状体１２を配置する配置工程と、配置工程よりも後に、天井スラブ３の上面３ａ側であって、管状体１２より上側に補強スラブ２を打設する打設工程と、打設工程よりも後に、管状体１２によって形成された閉鎖空間ＳＣ１に空気を供給して閉鎖空間ＳＣ１によって補強スラブ２を上昇させる流体供給工程と、流体供給工程によって補強スラブ２を上昇させている間に、天井スラブ３と補強スラブ２との間に補強スラブ支持部材８，９を設ける支持部材形成工程とを備えている。【選択図】図３
