Abstract

A general purpose construction element such as a post, pole, or beam is constructed from discarded used tire casings. Tire casings are first cut open and laid flat to form a mat. Then they are spirally wound in the fashion of a jelly roll so as to form a laminated composite post. The properties of the rolled post can be adjusted by adjusting the properties of the adhesive which is applied to one surface of the mat prior to rolling. The laminated rubber posts may rolled to predetermined sizes by appropriately preconfiguring the mat by juxtaposing or superposing multiple single tire mats. The laminated rubber posts have excellent strength, impact and vibration absorption, and machinability. The recycling of such non-degradable waste material as well as the provision of a superior replacement for natural wood is a double edged boon to the ecology.

Claims

1. An article for use as a multiple purpose construction element comprising;

a generally cylindrical and substantially solid composite post comprising;

a flexible mat spirally wound upon itself about an axis to form multiple overlapping layers, said axis coinciding with the cylindrical axis of said composite post, said flexible mat being formed from used tire casings having a series of slits in the sidewalls thereof, and

adhesive means interposed between adjacent ones of said multiple overlapping layers of said mat;

whereby

said adjacent ones of said layers are held together by said adhesive means so as to provide structural rigidity to said article.

2. The article of claim 1, wherein said adhesive means is applied to one surface of said flexible mat prior to spirally winding it into said composite post.

3. The article of claim 1, wherein the overall mechanical properties of strength, rigidity, and flexibility of said article are varied by choosing different adhesive means.

4. The article of claim 1, wherein said flexible mat comprises one or more used tire casings which have been cut open and flattened in such a manner so as to facilitate juxtaposing or superposing individual tire casings to preform said flexible mat into an appropriate size and shape to form said composite post to predetermined dimensions.

5. The article of claim 4, wherein said adhesive means is applied to an original tread side of said tire casings and said flexible mat is rolled such that an original smooth inside surface of each said tire casing forms the outside exposed surface of said cylinder.

6. At least two articles as in claim 4, in combination with electrical utility wires, wherein said articles are joined together to form a utility pole and a cross beam for supporting said electrical utility wires.

7. The article of claim 4, in combination with a highway guard rail, wherein a series of said article serve as supports for said highway guard rail and serve to enhance the impact energy absorption of said guard rail.

8. The article of claim 4, in combination with a street sign, wherein said article is used as a resilient upright support post for said street sign.

9. The article of claim 4, in combination with a fence, wherein a series of said articles serve as upright posts for said fence .

10. The article of claim 4, in combination with a street lamp, wherein said article provides both the physical support and the insulated conduit for said street lamp.

11. A method of producing a rolled composite construction element comprising the steps of:

(1) cutting through the circular ring of a used tire casing;

(2) cutting a series of generally radial slits in the side walls of said tire casing;

(3) unrolling said tire casing and folding back the portions of said sidewalls between said slits so as to form a relatively flat mat;

(4) applying an adhesive means to one surface of said mat;

(5) rolling up said mat, in a spiral manner, to form a layered but generally solid cylindrical article with alternating layers of tire casing and adhesive means;

(6) using said article as a general purpose construction element.

12. The method of claim 11, further comprising the step of refinishing the exterior surface of the cylindrical object with a shaping tool after the final rolling step.
