Title:
【発明の名称】合成ファイバ補強材を有する木製I字ビーム
Document Type and Number:
Japanese Patent JPH11502160
Kind Code:
A
Abstract:
The present invention includes wood I-beams with synthetic fiber reinforcement. In a preferred embodiment, a wood I-beam includes an opposed pair of elongated wood flanges and a substantially continuous web positioned between them. In one embodiment, the web includes multiple metal tubes that extend between the wood flanges and form a zig zag pattern. The ends of the metal tubes are flattened parallel to the plane of the metal web so the ends can fit within either slots in the top surface of the bottom wood flange or slots in the bottom surface of the top wood flange. Metal pins pass through the sides of the wood flanges and the flattened ends of the metal tubes to secure the tubular metal web to the flanges. In other embodiments the web includes oriented strand board (OSB) or plywood. Synthetic reinforcements are adhered to the wood flanges so that the metal pins also pass through the reinforcements. The synthetic reinforcements preferably include multiple synthetic fiber strands held within a resin matrix.
