Abstract
An integrally reinforced lineal building component including an elongated member having a substantially constant cross-sectional area along substantially the entire length of the building component and comprised of cellular material forming the body and major cross-sectional portion of the building component, and an elongated reinforcement element having a substantially constant cross-sectional area along substantially the entire length of the building component and disposed inside the elongated member and bonded integrally thereto. The reinforcement element is provided at least two flange-like portions integrally attached and disposed at an angle with respect to one another extending lengthwise of and generally parallel to the elongated member.
Claims32
An integrally reinforced lineal building component, comprising in combination:
- an elongated member having a substantially constant cross-sectional shape extending along substantially the entire length of said building component and comprised of cellular material forming the body and major cross-sectional portion of said building component;
- and
- an elongated reinforcement element having a substantially constant cross-sectional shape extending along substantially the entire length of said building component and disposed inside said elongated member and bonded integrally thereto, said reinforcement element having at least two flange-like portions integrally attached and disposed at an angle with respect to one another extending lengthwise of and generally parallel to said elongated member.
A method for forming an integrally reinforced lineal building component, including the steps of:
- forming an elongated member having a substantially constant cross-sectional area and comprised of cellular material forming the body and major cross-sectional portion of said building component;
- forming an elongated reinforcement element disposed inside said elongated member and having a substantially constant cross-sectional area and at least two flange-like portions integrally attached and disposed at an angle with respect to one another extending lengthwise of and generally parallel to said elongated member;
- and
- bonding said elongated member and said elongated reinforcement element integrally together.
