STRIP COMPOSITE CONCRETE FOUNDATION Russian patent published in 2024 - IPC E02D27/01 

FIELD: construction.

SUBSTANCE: invention relates to construction and can be used as strip foundation for residential and industrial buildings. Strip composite concrete foundation contains a concrete body, longitudinal rod, transverse rod fibreglass reinforcement in the form of clamps installed in the structure span at the reinforcement height with a pitch corresponding to the design crack pitch, and reinforcing U-shaped elements at the corners, combined with the longitudinal reinforcement, wherein fibreglass base of reinforcement core is impregnated with binder resins while reinforcement bearing rod has winding. Longitudinal rod, transverse rod fibreglass reinforcement in the form of clamps, as well as the reinforcing elements of the U-shape at the corners are made with an ellipsoidal cross-section, long axis of the reinforcement ellipse is combined with maximum loads on the strip foundation for longitudinal rod, transverse vertical and horizontal reinforcement, as well as reinforcing elements of U-shape at the corners. Fibreglass base of the reinforcement core in the form of fibre, impregnated with binding resins, is made with addition of quartz powder, which is uniformly mixed in the resin; the winding bundle is also made with addition of quartz powder.

EFFECT: increased bearing capacity of strip composite concrete foundation.
