RETAINER AND SLAB DEMOLITION METHOD
To provide a retainer for a slab etc., capable of suitably retaining the slab to be demolished so as to prevent cracks from occurring during demolition work for the slab.SOLUTION: A slab retainer 3 has a lock material 5, coupling materials 9, a support material 10, etc. The lock material 5 has arms 53 which are provided on an upper surface of a demolition part 1a of a slab 1, and a state of which can be switched between a state in which the arm straddles a disconnection position 13 between the demolition part 1a of the slab 1 and the slab 1 adjacent thereto and a state in which the arm retracts from the disconnection position 13. The support material 10 is provided on a lower surface of the demolition part 1a of the slab 1, and includes support beams 7 that are beam-shaped members. The coupling member 9 penetrates the demolition part 1a of the slab 1 to couple the lock material 5 and support material 10 with each other.SELECTED DRAWING: Figure 2
【課題】スラブの解体作業中に解体対象のスラブを好適に保持し、ひび割れ等の発生を防ぐことができるスラブの保持具等を提供する。【解決手段】スラブ保持具３は、係止材５、連結材９、支持材１０等を有する。係止材５は、スラブ１の解体部分１ａの上面に設けられ、スラブ１の解体部分１ａとその側方のスラブ１との間の切断位置１３を跨いだ状態と、切断位置１３から退避した状態とを切替可能なアーム５３を有する。支持材１０は、スラブ１の解体部分１ａの下面に設けられ、梁状部材である支持梁７を含む。連結材９は、スラブ１の解体部分１ａを貫通し、係止材５と支持材１０とを連結する。【選択図】図２
