Abstract: Simulated beam construction which has a central elongated I-beam member having opposing ends for connecting to opposing side panel members. The side panel members each have opposing lateral ends and later elongate panels extending between the lateral ends so as to enclose the central elongate I-beam. Flanged grooves on the lateral ends for sliding attachment to the lateral panels. The simulated wood beam construction has an I-beam member which is an elongate member, that when viewed in cross-section, has flanges or flanged slots on each opposite end for co-operative engagement with the opposing panel member. As an alternate embodiment it may be preferable to construct the I-beam of two substantial identical elongate members, fastened one to the other.

Abstract: A simulated beam construction comprises a rectangular elongated core member with several laterally arranged prongs or barbs. Wooden, laminated wooden or plastic planks with a lateral channel are fitted closely together and adapted to receive one of the barbs for the anchoring of the planks along the core member. Two L-shaped planks are arranged on opposite sides of the extrusion member such that the horizontal legs abut each other and cooperate with the other laterally arranged planks to enclose the core member.

Abstract: An assembly for securing roof panels at selectable pitch angles includes an extruded ridge bar having a horizontal ledge and a horizontally extending arcuate flange which form a horizontal slot in which the roof panels are supported at the desired pitch. Horizontally extending end portions of the arcuate flange are removable to set the angle of the slot for the desired pitch. Roof support bars extending along the side edges of the roof panels are connected to the ridge bar at the selected pitch by hinge assemblies having their pivot axes coincident with the center of curvature of the arcuate flange. A header supporting the panels at the eave comprises two extruded channel members pivotally connecting one flange of each channel member. A bifurcated arcuate end portion of the other flange on one channel member straddles the arcuate end portion of the other flange on the other channel member as the channel members are rotated to set the selected roof pitch.
