REINFORCING METHOD FOR OVERHUNG SLAB
PROBLEM TO BE SOLVED: To provide a reinforcing method for an overhung slab that resolves problems related to economy and securing of a work site, at the same time dealing with decline in bearing capacity caused by an increase in exerted forces and corrosion of steel materials.SOLUTION: In a reinforcing method for an overhung slab, an overhung slab 31 is made partially thicker and an anchor bar is used therewith, thus mitigating tensile stress on a reinforcing bar of the overhung slab 31, and members near a junction between a column and a beam are partially and effectively made thicker in consideration of an effective width of the stress, at the same time installing a shear reinforcing bar and a steel plate using hole-in anchors, thus mitigating stress concentration on the overhung slab close to the reinforcing member 30, and enhancing integrity with an existing structure using the reinforcing part.SELECTED DRAWING: Figure 10
【課題】 張出しスラブの補強にあたり、経済の問題、および作業用地の確保を図りつつ、増加する作用、鋼材腐食等の耐力低下に対応することができる、張出しスラブの補強工法を提供する。【解決手段】 張出しスラブの補強工法において、張出しスラブ３１に部分的増厚とアンカー筋を併用し、前記張出しスラブ３１の鉄筋への引張応力を低減し、応力の有効幅を考慮して柱・梁接合部付近を部分的かつ効果的に増厚し、あと施工アンカーによりせん断補強筋および鋼板を配置し、前記補強部材３０近傍の張出しスラブに集中して生じる応力を緩和し、前記補強部により既設構造物との一体性を高める。【選択図】 図１０
