To provide a suspending frame device of a plate-like body that can reduce deflection caused when lifting a mat, easily performs positioning during laying, does not apply tension to a slinging wire rope, can be easily removed, and can be laid when there are two or more points of gradient changes regardless of a gradient angle of a cross section, and a laying method.SOLUTION: The suspending frame device includes a body suspending frame 19, which uses a vertical beam 15 of a suspending frame including a vertical beam 15 and a transverse beam 16 as an articulated frame, and an auxiliary suspending frame 18, which suspends the body suspending frame 19 and is suspended from a crane.SELECTED DRAWING: Figure 1
【課題】マットを吊り上げた時のたわみを小さくでき、敷設時の位置決めも容易にでき、玉掛けワイヤーロープにテンションがかからず、取り外しが容易であり、断面の勾配角度によらず、かつ、勾配変化が2箇所以上の場合も敷設が可能な板状体の吊り枠装置および敷設工法を提供する。【解決手段】縦梁15と横梁16からなる吊り枠の縦梁15を多関節フレームとした本体吊り枠19と、この本体吊り枠19を吊支し、クレーンから吊支される補助吊り枠18とからなる。【選択図】図1
