[0023] 3. Through the concrete connector composed of a concrete top strip, concrete side panels, a support frame, and a concrete bottom strip, the concrete side panels cast on the lower surface of the concrete slab are in contact with the outer surface of the support sleeve, so that the column limits the concrete slab through the support sleeve and the concrete side panels, and the concrete top strip and support frame cast on the lower surface of the concrete slab, and the concrete bottom strip cast at the lower end of the support frame are supported by the connecting sleeve, thereby increasing the stability of the concrete connector supporting the concrete slab.

[0024] 4.
