FIELD: construction, particularly floor structure.
SUBSTANCE: adjustable support for floor leveling or to construct floor spaced a distance from floor base includes cylindrical rod made of polymeric material and provided with outer thread and flange connected to end thereof facing floor base. Support also has pressing plate made of polymeric material and having parallelepiped shape. The pressing plate includes fastening orifices for plate connection to floor base and central orifice to receive cylindrical rod so that the rod may rotate in axial direction. Central orifice has diameter increasing stepwise towards floor base so that depression for rod flange receiving is formed in lower plate surface. Flange thickness exceeds depression depth. Cylindrical rod is made as a solid body or has longitudinal blind channel opened from flange side and coaxial to central rod axis.
EFFECT: increased load-bearing ability of floor structure.
