Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
132 words
A panel for use in a modular concrete form, comprising laterally adjustable and interfitting first and second open framework sections each including an upright side member and upper, lower and intermediate members extending laterally from the side member, means releasably connecting the upper, lower and intermediate members of the first section in laterally overlapping relation to the upper, lower and intermediate members, respectively, of the second section, the faces of the upright, upper, lower and intermediate members providing a front side of the panel to which a flat skin will be secured, a wale, and means releasably connecting the wale to laterally overlapping portions of said upper, lower and intermediate members of said first and second sections for maintaining it tightly against the faces thereof on the back side of the panel.
