Filed:

Jan 7, 1998

Appl. No.:

9/003747

Inventors:

Kenneth P. Lanahan - Troy IL
Thomas G. Durham - Ava MO
Stephen C. Foreman - Las Vegas NV

Assignee:

QB Technology - Ava MO

International Classification:

B23P 1500

US Classification:

2989732

Abstract:

A method for producing a polymeric foamed material panel including the steps of providing a polymeric foamed material; and cutting (e. g. hot wire cutting) the polymeric foamed material until reaching a preconfiguration cut point. The method further includes cutting subsequently from the preconfiguration cut point a brace-receiving configuration in the polymeric foamed material; and sliding a brace member into the brace-receiving configuration to produce a polymeric foamed material panel. A method for forming a structure comprising engaging together a pair of polymeric foamed material panels produced in accordance with the method for producing a polymeric foamed material panel. A polymeric foamed material panel comprising a panel consisting of a polymeric foamed material, and a brace-receiving-configured slot disposed in the polymeric foamed material of the panel. A brace member is disposed in the brace-receiving-configured slot in the polymeric foamed material of the panel. The brace-receiving-configured slot includes at least one seared wall.
