Methods and systems for making and using a wide swath offset concrete screed apparatus for screeding wet concrete slurry. The apparatus includes a cross support bar, an attachment mechanism for attaching the cross support bar to a liftable arm of a motorized vehicle, and lateral support bars for attaching a screed bar to the cross support bar. The screed bar is positioned offset from the motorized vehicle used to operate the screed, allowing the motorized vehicle to drive outside the forms.

A screed hook apparatus includes a tubular collar having an opening through a sidewall thereof. A tubular retainer member is aligned with the opening on the collar and extends away from an outer surface of the collar. The retainer member has a threaded internal wall surface. The apparatus also includes an arm forming a hook shape. The arm has a first portion extending away from the collar and a second portion extending transverse to a direction of extension of the first portion such that a surface of the second portion of the arm faces the sidewall of the collar. A set screw has a threaded portion to engage the threaded internal wall surface of the retainer member, and a handle is attached to the set screw.

The present invention provides an adjustable, universal screed guide/control joint clip for positioning screed guide/control joints utilized in the placement of concrete in concrete slabs. The adjustable universal screed guide clip allows for the exact adjustment of the height of the screed guide attached thereto for the placement of the concrete slabs, and the adjustable universal screed guide clip also allows for the installation of the screed guide in applications which heretofore were not possible. The adjustable, universal screed guide/control joint clip of the present invention is capable of accommodating both large and small profile screed guides.

A screed beam support apparatus for supporting a screed beam at a desired height above a ground surface includes a clamp and a hook. The clamp secures the hook to a vertical post to position the screed beam at the desired height. The clamp uses a set screw with a handle that extends perpendicularly to the set screw. The handle facilitates increasing a torque applied to the set screw by a user via a lever action.

Systems and methods of shotcrete construction are contemplated whereby guide rails are placed in proximity and forward to a shotcrete receiving surface, with any guide rails disposed directly in front of the shotcrete receiving surface being configured to be offset from the receiving surface allowing shotcrete to be sprayed behind the offset guide rails. Following application of shotcrete, a screed configured to engage with and traverse along at least two of the guide rails may be used to rod the shotcrete via a protruding region of the screed extending beyond the guide rails, thereby removing excess shotcrete and imparting to the shotcrete surface a contour at least partially defined by the configuration of the guide rails and the configuration of the protruding region of the screed. Complex, precise, and even exotic architectural shotcrete installations may be created in this fashion by providing a suitable set of guide rails and screed.
