METHOD OF MAKING 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. Method of making strip composite concrete foundation includes preparation of elements and installation of reinforcing frame consisting of longitudinal rod, transverse rod composite reinforcement in the form of clamps installed in the span of the structure at the height of reinforcement with a pitch corresponding to the design pitch of cracks, and reinforcing U-shaped elements at corners, combined with longitudinal reinforcement, installation of formwork, filling with concrete tape at a time. Longitudinal, transverse and reinforcement in the form of clamps are made of basalt reinforcement in the cross-section of an ellipsoid shape, wherein the long axis of the ellipse is aligned with the direction of the maximum load of the cross section of the foundation, the lengths of the axes of the ellipse are taken in proportion to the design loads along the axes of the cross section in the middle of the length of the span of the foundation. When preparing the transverse rod basalt reinforcement in the form of clamps, the corners are bent and simultaneously the sides of the rectangle are turned through 90° around longitudinal axis of reinforcement, with their preliminary heating by gas burner and with arrangement of long axis of ellipse for transverse vertical reinforcement perpendicular to plane of clamp, and for transverse horizontal reinforcement along plane of clamp. Installation of linear sections of the reinforcing frame is preliminary carried out in a template which enables to align the long axis of the ellipse of the basalt reinforcement with maximum loads on the strip foundation, and with subsequent installation of the common reinforcing frame at the location of the strip composite concrete foundation.

EFFECT: increased bearing capacity of strip composite concrete foundation.
