초록 ▼

This invention relates to a wooden beam built up of two chord members separated by two web members forming a rectangle with the chord members. The chord and web members may be made of solid wood, Oriented Strand Board (OSB) Laminated Veneer Lumber (LVL), Waferboard or Veneer. The wooden beam is made of upper and lower chord members and two planar web members all interconnected by means of mechanical and adhesive secured joints. The overall outline of the section shape of the fabricated wooden beam is similar to standard lumber and can be made to fit the same standard dimensions available on the market or any other dimension, allowing for easy assembly with existing apparels and equipment. Chord members are extended by a finger jointing method; longitudinally extending grooves are provided on each side of a chord member, near an edge. Web members have their ends provided with a tongue shaped as to substantially fit in the chord members grooves.

대표청구항 ▼

A fabricated wooden hollow beam of a generally rectangular cross section for use in structural applications, said fabricated wooden hollow beam comprising: a pair of chord members each having an interior face (32) comprising two edge corners, a raised central part defining a rectangular tenon (51), two longitudinal grooves (54) adjacent to said rectangular tenon (51) and two intermediate sites (70) located between said longitudinal grooves (54) and said edge corners, said rectangular tenons having two opposed faces (56) having a length and extending into said longitudinal grooves (54), forming an integral part thereof, each longitudinal groove having a depth and a width, said length of said opposed faces being equivalent to twice the depth of said longitudinal grooves, a pair of planar web members having an external face (42), an internal face (44) and opposed edges for interconnecting said chord members, each one of said opposed edges comprising a tongue (46) terminated by a mating end (48) and located near an end of said internal face (44), said opposed edges also comprising a web shoulder (50) located between said tongue (46) and a corresponding end of said external face (42), said longitudinal grooves receiving said web members opposed edges, and held together by a thin film of adhesive (64), wherein the abutting of said internal face (44) against said opposed faces (56) of said tenon (51), the insertion of said mating end (48) into said grooves (54) and the abutting of said web shoulder (50) against said site (70) coupled with the presence of a thin film of said adhesive (64) onto said matching fit, causing the firm jointing of said fabricated wooden hollow beam.
