ABSTRACT:
The present invention relates to a canvas reinforcement structure which enables canvas to become strong enough to sustain greater external force (such as wind), and enlarge tension strength to avoid breakage as well as form overall restraint effect for obtaining whole covering performance; it comprises reinforcement corner block mounted on respective corners of canvas, and corner block including upper and lower reinforcement pieces to form contact limited room and outlet hole for retaining canvas and therefore rivetting together with canvas by means of rivet; central position having through hole, collar rope hole for building up each corner of canvas with resistant ability against tearing force without risk of breakage; and restraint portion is folded with appropriate width of canvas for inserting restraint rope and auxiliary rope wrapping body so as to strengthen resistance of canvas periphery against lifting over as well as reinforcing the effect of secure tying. The improved canvas for corner strength and covering in position compared with conventional canvas, may achieve endurable effect against breakage and excellent covering performance thereof.
