Forms and screed for paving materials

Abstract

An apparatus for installation of paving materials has a screed that is configured to extend across a gap between first and second forms, wherein the first and second forms are piecewise parallel with respect to each other. The screed has at least a first section that is coupled to a second section. The screed has a first height adjusting member with a first seat surface for slidable contact along the first form and a second height adjusting member with a second seat surface for slidable contact along the second form. The first and second height adjusting members are adjustable to set the height and angle of the at least first and second sections of the screed within the gap.

1 . An apparatus for installation of paving materials, the apparatus comprising a screed that is configured to extend into and across a gap between first and second forms, wherein the first and second forms bound the sides of the paving materials within the gap and are substantially piecewise parallel with respect to each other,
 wherein the screed has at least a first section that is coupled to a second section,   and wherein the screed has a first height adjusting member with a first seat surface for slidable contact along the first form and a second height adjusting member with a second seat surface for slidable contact along the second form and wherein the first and second height adjusting members are each adjustable to set the height and angle of the at least first and second sections of the screed within the gap.   
     
     
         2 . The apparatus of  claim 1  wherein the screed further has at least one bucket accepting coupling, wherein the at least one bucket accepting coupling has a slot that extends along the screed in a length direction for accepting a portion of a lip of a bucket for an earth-moving apparatus. 
     
     
         3 . The apparatus of  claim 2  wherein the at least one bucket accepting coupling is clamped to at least the first section of the screed. 
     
     
         4 . The apparatus of  claim 1  wherein both the first and second parallel forms have an inner surface that faces the gap and wherein one or both of the inner surfaces have markings that are indicative of the height of the paving materials within the gap. 
     
     
         5 . The apparatus of  claim 4  wherein one or more of the form sections has channels for accepting couplings that join the form sections. 
     
     
         6 . The apparatus of  claim 1  wherein the first and second screed sections present a curved profile for providing a convex or concave shape to the paving material. 
     
     
         7 . The apparatus of  claim 1  further comprising an anchor coupling that is coupled to the first form and that provides a linkage between the first form and a stake driven into the ground. 
     
     
         8 . The apparatus of  claim 7  wherein the anchor coupling links to a stake that is driven into the ground at an oblique angle. 
     
     
         9 . The apparatus of  claim 7  wherein the anchor coupling further adjusts with respect to one or more of the horizontal, lateral and vertical positions of the first form. 
     
     
         10 . An apparatus for installation of paving materials, the apparatus comprising a screed that is configured to extend into and across a gap between first and second forms, wherein the first and second forms bound the sides of the paving materials within the gap and are substantially piecewise parallel with respect to each other, wherein the screed has:
 (i) at least a first section that is coupled to a second section;   (ii) a first height adjusting member within a first cavity and having a first seat surface for slidable contact along a first contact surface of the first form;   (iii) a second height adjusting member within a second cavity and having a second seat surface for slidable contact along a second contact surface of the second form and wherein the first and second height adjusting members are each adjustable to set the height and angle of the at least first and second sections of the screed within the gap;   and   (iv) at least one bucket accepting coupling, wherein the at least one bucket accepting coupling has a slot that extends along the screed in a length direction for accepting a portion of a lip of a bucket for an earth-moving apparatus.   
     
     
         11 . The apparatus of  claim 10  wherein the first seat surface is flat. 
     
     
         12 . The apparatus of  claim 10  wherein the at least first and second sections are adjustable to provide a concave or convex curvature profile within the gap. 
     
     
         13 . The apparatus of  claim 10  wherein the position of the at least one bucket accepting coupling along the length direction of the screed is adjustable. 
     
     
         14 . The apparatus of  claim 10  wherein both the first and second parallel forms have an inner surface that faces the gap and wherein one or both of the inner surfaces have markings that are indicative of the height of the paving materials within the gap.
