Screed Rail Guide Connector System

Abstract

A series of dual-transverse-tubular screed rail guide connectors are slidably attached to a cooperating series of vertical support rods driven into a substrate at defined intervals to establish a pavement grade and perimeter. Each connector comprises an adjustable horizontally-oriented tubular sleeve that is slidably attachable at variable heights to a support rod by means of an integral vertically-oriented tubular clamp. Sections of tubular screed rail guides are inserted through the tubular sleeves of the connectors to define the perimeter of the area to be paved.

1 . A method for establishing a pavement grade and a pavement perimeter of a poured paving material, comprising the following steps:
 (a) driving multiple support rods into a substrate at support intervals around the pavement perimeter;   (b) attaching a dual-transverse-tubular connector to each support rod at a grade elevation corresponding to the pavement grade at the location of each support rod; wherein the dual-transverse-tubular connector comprises a horizontally-oriented tubular guide sleeve and a vertically-oriented tubular rod clamp, such that the tubular guide sleeve is slidably attachable at variable heights to one of the support rods by the tubular rod clamp, through which a set bolt is threaded and tightened;   (c) inserting each of multiple sections of tubular screed rail guide through the tubular guide sleeves of multiple dual-transverse-tubular connectors, such that the sections of screed guide rail are supported at the grade elevation by the support rods and fully enclose the pavement perimeter;   (d) pouring the paving material within the pavement perimeter until its level exceeds the grade elevation; and   (e) leveling and compacting the paving material by mechanically or manually drawing a screed rod or rail along the upper surface of the screed rail guide.
