Modular element ridged roofing over rectangular space - incorporating sets of four identical right-angled triangular elements

摘要

The roofing or covering is for any rectangular-plan space. One of the surface elements or both, is assembled from four equal modular elements of right-angled triangular shape, with the shortest sides of two combining to form the ridge, and the longer short sides each forming a side edge. The space between the hypotenuses of these two is filled by the other two triangles of the set of four, hypotenuse to hypotenuse, with the shortest sides of all in a plane parallel to the ground, and the short sides of the first pair at right angles to those of the second. The edges may be hollow-shaped sections. A series of such sets may be used for roofing large areas.
