DEVICE OF GAPLESS AUTOMATIC COMPENSATION OF TEMPERATURE DEFORMATIONS OF CEMENT CONCRETE FOUNDATIONS (SURFACES) OF MOTOR ROADS Russian patent published in 2014 - IPC E01C11/04 

FIELD: construction.

SUBSTANCE: invention relates to devices for compensation of temperature deformations of lengthy cement-concrete (foundations) surfaces. A cement-concrete foundation is fully divided by a triangular plate of a compensator, which by its sides couples with side surfaces of divided foundation boards. All coupled side surfaces of the boards are contoured with angles, shelves of which are located to the plane of the foundation at the angle of 45°, their tops are directed towards the boards of the divided foundation. Between coupled shelves of angles there is an anti-friction pad or an anti-friction lubricant. The triangular board of the compensator has a dead channel passing in parallel to the foundation of the board and in the middle having a widening for installation of a spring device. A levelling rope is fixed to the ends of the spring device. It reaches to both sides of the triangular board of the compensator, via windows in angles of edges of side surfaces of the boards, to blocks of the levelling rope that rotate on axes fixed in bodies of the blocks concreted into divided boards of the foundation. Then after winding of the blocks the ends of the rope perpendicularly to the axis of the road direction enter channels of the compensator board for anchoring at the distance equal to half of the middle length of the levelling rope (from the middle to the place of rope crossing as it enters and exits the block).

EFFECT: structure makes it possible to hold side surfaces of a triangular compensator board as continuously pressed to side surfaces of divided foundation boards, and opening or closing of divided foundation boards due to availability of a levelling rope, permanently, via a spring device, which supports rated pressing of side surfaces of a board to each other, causes movement of a triangular compensator board either towards its foundation, or towards the top, compensating variation of the distance between divided foundation boards during their thermal deformations without formation of gaps between side surfaces.
