FORMWORK MATERIAL AND METHOD OF CONSTRUCTING CONCRETE STRUCTURE WITH USE THEREOF

摘要

[PROBLEMS] To provide a concrete formwork that avoids the problem of detachment at junction of multiple panel main bodies and that is used to construct a building from which satisfactory heat insulation effects can be expected. [MEANS FOR SOLVING PROBLEMS] Both major surfaces of metal core member (1) with a shape of cross section corrugated are laminated with hard foam resin (2), thereby obtaining panel main body (P). This panel main body (P) on its at least one surface is provided with waterproof layer (8). The panel main body at its both sides opposite to each other is provided with joining margins (9,10) having one surface of the corrugated core member exposed.
