Zusammenfassung:	PURPOSE:To safely and easily disassemble a timbering stay by a method wherein the lower part of the timbering stay is supported by means of a fluid particulate matter by means of which surroundings are constrained, after ceiling forms are propped with the stay, in disassembly, the fluid particulate matter are released from constrainment by surroundings. CONSTITUTION:A timbering stay 4 formed with a stay body 5, a screw type jack 7, and a form support member 6 is erected on a support device 1, and a ceiling forms 2 are propped against a floor 3 for support. The support device 1 is formed such that a box body 8 having an opening slightly larger than a bottom plate 5a of the support body 5 is filled with a fluid particulate matter (a). In disassembly of the timbering stay 4, the fluid particulate matter (a) in the boxy body 8 of the support device 1 is released from constrainment produced by surroundings, and support by the timbering stay 4 is rendered ineffective. As a result, a powerful bearing exerted on the timbering stay 4 is removed, and the screw type jack 7 can be safely and easily contracted.
