FIELD: construction engineering, in particular, floor construction methods.

SUBSTANCE: method for building floors includes setting up beacons on base and applying porous building mixture onto base, as which construction compound foaming after being applied or foamed preliminarily is used. In first case, construction compound is applied onto base in form of layer, height of which after end of foaming exceeds height of beacons, sheet cover is placed onto beacons before beginning of foaming and is exposed until completion of foaming and precipitation of compound under effect from weight of cover. In second case, construction compound is applied onto base in form of layer, height of which exceeds height of beacons, after than onto layer of compound after its hardening sheet cover is placed and is exposed until completion of compound precipitation under effect from weight of cover. In case when construction compound applied onto base only performs function of tie for next sheet cover, it is recommended prior to placing to process sheets of cover with composition, increasing adhesion of sheet material to concrete; sheets of cover for provision of additional rigidity may be fastened to beacons and/or hardened layer of compound. In case of working conditions for premises allow concrete floor, sheet cover, after hardened construction compound accumulates hardness, is removed and used repeatedly at other sections. If construction compound applied to base performs function of tie for cover, different from one used during compound hardening, it is recommended to process sheets of cover prior to placement with composition decreasing adhesion of sheet material to concrete.

EFFECT: simplification of technological process.
