Abstract

A method for utilizing discarded tires is disclosed which creates strong, durable, posts, beams, mats, blocks or other structures. Used tires are cut and flattened and the sidewalls are removed. The tread sections of the tires are cleaned. Vulcanizing compound is then applied to adjacent inner surfaces of the tread sections to form a flat essential building element. These building elements may be vulcanized together in alternating horizontal and perpendicular layers to form flat blocks, mats, noise or safety barriers, or other structures. The essential building elements are flat and form structures which have flat upper and lower surfaces and a rectangular cross-section. Beams may be formed by securing a number of the essential building elements together to form structures that are approximately 8 feet high and have a rectangular cross-section.

Dependent claims

A method of producing a useful structure from used tires having a tread section and a sidewall section comprising the steps of:

(a) Cutting a plurality of tires across their cross-sections;
(b) Cutting the sidewalls from said tires, creating two sidewall sections;
(c) Cleaning the inner surface of the sidewall sections of each tire thoroughly;
(d) Applying a vulcanizing compound to the inner surface of said sidewall sections of each tire;
(e) Pressing the inner surface of two of said sidewall sections, having said vulcanizing compound applied, together, to form a flat, elongated essential sidewall building element structure;
(f) Cutting said elongated essential sidewall building element structure into building elements that are approximately six inches long and three inches wide;
(g) Applying a vulcanizing compound to the outer surfaces of a plurality of said essential sidewall building element structures;
(h) Pressing a plurality of said essential sidewall building elements, having said vulcanizing compound applied, together, using approximately 3,000 psi for approximately four hours, to form a brick structure having flat, parallel upper and lower surfaces and flat, smooth regular sides and ends.
