Abstract
Abstract A mold for casting a concrete test beam having precise crosssectional and length dimensions, the mold being formed from heavy gauge sheet metal and having a bottom panel with downwardly extending side flanges, a pair of side panels having outwardly extending end flanges and a top flange along the upper edge of the side panel, and end panels having a height, in use, equal to that of the side panels, and a minimum of at least two bolts fixed to each of the end flanges of the side panels and the side flanges of the bottom panel for projection through complementary holes in the abutting portions of the other panels which engage the same, whereby wing nuts tightly and effectively clamp the side panels to the bottom panel and connect the end panels to the side panels in a substantially watertight manner, the end panels also having handles projecting outwardly therefrom and the upper flanges on the side panels providing guide surfaces for a striking tool to level the concrete when poured into the mold.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
237 words
A mold for casting a concrete test beam of precise dimensions comprising in combination, a rectangular flat bottom panel having opposite side edge portions sharply bent perpendicularly thereto into parallelism with each other to form a pair of supporting and reinforcing flanges, the outer edges of said flanges being engageable with a supporting surface in use to support said panel in spaced relation to such supporting surface, a pair of complementary flat rectangular side panels having a length similar to said bottom panel and the opposite end portions and one side edge portion thereof being sharply bent perpendicularly thereto to form flanges, the other side edge portions of said panels being adapted respectively to overlie and coincide as a supporting edge with said supporting flanges of said bottom panel, whereby similar bent end portions of said side panels lie and extend outwardly from each other within common planes with each other and the ends of said bottom panel when said side panels are connected thereto, a pair of flat end panels respectively adapted to extend across the ends of said side panels and overlie said bent end flanges thereof, threaded bolts connected to certain of said overlying portions of said panels and flanges adapted to project through complementary holes in the abutting panels or flanges, and nuts threadable upon said bolts to secure said side and end panels detachably connected to each other and said bottom panel.
Claim 2
Dependent Claim

A mold for casting a concrete test beam of precise dimensions comprising in combination, a rectangular flat bottom panel having opposite side edge portions sharply bent perpendicularly thereto into parallelism with each other to form a pair of supporting and reinforcing flanges, the outer edges of said flanges being engageable with a supporting surface in use to support said panel in spaced relation to such supporting surface, a pair of complementary flat rectangular side panels having a length similar to said bottom panel and the opposite end portions and one side edge portion thereof being sharply bent perpendicularly thereto to form flanges, the other side edge portions of said panels being adapted respectively to overlie and coincide as a supporting edge with said supporting flanges of said bottom panel, whereby similar bent end portions of said side panels lie and extend outwardly from each other within common planes with each other and the ends of said bottom panel when said side panels are connected thereto, a pair of flat end panels respectively adapted to extend across the ends of said side panels and overlie said bent end flanges thereof, threaded bolts connected to certain of said overlying portions of said panels and flanges adapted to project through complementary holes in the abutting panels or flanges, and nuts threadable upon said bolts to secure said side and end panels detachably connected to each other and said bottom panel.
Claim 3
Dependent Claim
58 words
The mold according to claim 1 in which said flanges on the side edges of said side panels are within a common plane parallel to said bottom panel when said panels are connected thereto, whereby said flanges serve as guide surfaces for a striking blade to level concrete within the mold at the completion of a filling operation.
Claim 4
Dependent Claim
63 words
The mold according to claim 1 in which there are at least two bolts connected to each end flange of said side panels and each supporting flange of said bottom panel, said bolts being spaced apart from each other and inwardly from the ends of said flanges to insure tight abutment of the overlying portions of said panels and flanges with each other.
Claim 5
Dependent Claim
82 words
The mold according to claim 1 in which said end panels when connected to the end flanges of said side panels having an uppermost edge in use lying within the plane of said flanges along the side edge portions of said side flanges and the opposite edge of said end panels lying substantially within the plane of the outer edges of the flanges of said bottom panel, and said end panels having U-shaped handles connected to the outer surfaces thereof in use.
