Backlash-free device for self-compensation of temperature deformations cement concrete pavement (base) HIGHWAYS

摘要

FIELD: construction.;SUBSTANCE: cement-concrete foundation is fully separated by triangular boards of a compensator, tops of which are directed towards each other, and the line that connects them is perpendicular to the foundation axis. By their side surfaces these boards, capable of gapless mutual slipping, are coupled with side surfaces of separated foundation boards with the help of steel angles laid along the separation line so that increasing or decreasing of separated foundation board sizes due to thermal deformations is compensated in the automatic mode by appropriate approaching or divergence of compensator triangular boards from each other.;EFFECT: gapless autocompensator preserves solidity of a cement-concrete surface thus increasing traffic safety, increases durability of operation, reduces costs for maintenance of a cement-concrete surface in a normal condition.;3 cl, 4 dwg
