Abstract

The method of making cast barrier structures consisting of the steps of, securing a plurality of form plates in a longitudinally spaced array over a supporting surface with the major plane of each form plate oriented substantially vertically and transversely to the length of the array, positioning side panels longitudinally alongside the form plates on opposite sides thereof and extending the length of the array, the side panels having upper and lower longitudinally extending edges with the lower edges seated on the underlying supporting surface and having irregularities on the inside surface which faces the form plates, fixedly securing the side panels to the form plates to form with the form plates and underlying surface an open-topped hollow assembly, and pouring a solidifiable plastic material downward through the open top of the hollow assembly to completely fill the interior thereof and integrally bond together the form plates and the side panels and the plastic material when the latter solidifies.

Claims

1. The method of making cast barrier structures consisting of the steps of,

(a) rigidly securing a plurality of upstanding form plate supports to an underlying supporting surface,

(b) securing a plurality of form plates to said plurality of upstanding form plate supports in a longitudinally spaced array over said supporting surface with the major plane of each form plate oriented substantially vertically and transversely to the length of the array,

(c) projecting reinforcing rods longitudinally through the full length of the array of form plates through the planes of the form plates, and securing the rods to the form plates,

(d) positioning side panels longitudinally alongside the form plates on opposite sides thereof and extending the length of the array, said side panels having upper and lower longitudinally extending edges with the lower edges seated on the underlying supporting surface and having irregularities on the inside surface which faces the form plates,

(e) fixedly securing said side panels to said form plates to form with said form plates and underlying surface an open-topped hollow assembly, and

(f) pouring a solidifiable plastic material downward through the open top of said hollow assembly to completely fill the interior thereof and integrally bond together with said form plate supports, said form plates, said reinforcing rods, said side panels and said plastic material when the latter solidifies.

2. The method of making cast barrier structures as set forth in claim 1 further including the step of placing a capping panel downward over the open top of the assembly after the solidifiable plastic material has been filled thereinto and while such material is still in a plastic condition, the capping panel covering the open top and including downward facing projections projected into the plastic material to lock the capping panel to the rest of the assembly when the plastic material solidifies.
