Continuous, precast, prestressed concrete bridge deck panel forms, precast parapets, and method of construction

摘要

This invention provides an improved and more efficient method and articles of manufacture to construct new bridge decks, or to replace existing bridge decks. This unique method of constructing deck slabs utilizes precast, prestressed concrete form panels that are continuous over the floor beams or supporting walls. A cast-in-place concrete topping is placed on the form panels and finished to the proper grade to become the top surface of the slab. The cast-in-place topping also bonds to the roughened top surface of the precast, prestressed form panels and acts with the panels to create a structural deck slab. In addition, this invention embodies a new method and article of manufacture and installation for precast parapets, safety curbs and traffic divisors which are attached to a precast, prestressed continuous panel positioned on the supporting beams, or a conventional bridge deck.
