FIELD: construction.
SUBSTANCE: invention relates to tooling-mould, and can be used in device monolithic floors and coatings. Pneumatic element of covering formwork solid ceiling is made from elastic flexible material in form of pneumatic mat 1. Larger faces 2, 3 mat 1 consist of permanent two layers 4, 5. Inner layers 4 are connected by non-stretch thread 6. On edge 3 there are loops 7 for fastening flexible elements 8 for attachment of mat 1 to crate a formwork and 9 to secure (tightening) mats 1 with formation of flooring. On edge 3 there is also inlet-outlet valve 10. On edge 2 along one of its ribs there is elastic flexible pad 11 extending beyond mat 1.
EFFECT: higher quality of work owing to preventing waviness of ceiling (bottom) of overlapping.
