BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a novel and improved panel and panel assembly for use in building-type structures and to novel panel-forming apparatus.
BACKGROUND ART
In prior U.S. Pat. Nos. 3,842,647, 3,902,288 and 3,967,430 of the same inventor as the present invention, there are disclosed a shaped panel characterized by parallel sidewall portions that are perpendicular to an intermediate wall portion and a flange that extends directly laterally out from the upper extremities of the sidewall portions so that assembled panels have sidewall portions that fit flush against one another.
DISCLOSURE OF INVENTION
A relatively wide panel and an assembly of the panels are disclosed which are suitable for forming the roof, sidewalls and end walls of a self-supporting building-type structure. The panel has an intermediate wall portion, a pair of opposed, upwardly diverging, inclined sidewall portions, and a pair of parallel upper side sections that abut against one another when two of the panels are joined side by side. One form of the panel has the upper side section disposed at an incline and has a pair of wing portions of substantial lateral extent in relation to the intermediate wall portion between the upper side section and the inclined sidewall portions, together with male and female edge fastening means extending beyond the upper side section and above the wing portions. Each wing portion, upper side section, and associated edge fastening means has a dimension related to the dimension of the intermediate wall portion to provide a balanced structure that has substantially the same resistance to both compression and tension loading forces when two of the panels are connected side by side. The edge fastening means of a pair of adjacent panels are located above and substantially centered between the edges of adjacent wing portions which are connected along a continuous seam structure. Another form of the panel does not have the wing portions and has upper side sections that extend vertically up from the lateral extremities of the inclined sidewall portions. Forming apparatus for changing a straight panel to a curved panel is arranged for forming transverse indentations in the intermediate wall portion and each of the sidewall portions. The forming apparatus includes separate, alternately operable pairs of indenting dies, each with a hydraulic drive using a hydraulic control system with one idling while the other is being driven.
