This degree of design inefficiency increases in direct proportion with any increase in the depth of the beam. This degree of inefficiency can easily exceed 50% in many practical applications.
In my U.S. Pat. No. 5,219,473, issued Jun. 15, 1993, I disclose and claim an invention which pertains to a novel adjustable formwork system which can be used in the manufacture of a wide range of structurally efficient cross-sectional shaped concrete beams, walls, columns and structures. In one version, a cast-in-place concrete beam form can be constructed comprising at least two spatially oriented upper sleeves with an upper web located on one side of the two sleeves, and extending therebetween, at least two spatially oriented lower sleeves, with a lower web located on one side of the two sleeves, and extending therebetween, and at least two members, each member conducting telescopically the respective upper sleeve with the respective lower sleeve, the telescoping members enabling the two upper sleeves to be raised or lowered relative to the two lower sleeves. FIGS. 30 through 34 of that U.S. patent, in particular, disclose a system for constructing a form of adjustable height comprising a series of upper sleeves 70, which can be raised upon corresponding sliders 98, relative to a corresponding series of lower sleeves 72. The system conforms with standard pieces of lumber, 2.times.4, 2.times.6, 2.times.8, etc., and the like, that are used in commercial concrete construction. The slider 98 is normally formed of aluminum. Keeper plates 82 are secured in place with standard snap-ties 74 extending through the upper sleeve, or the lower sleeve respectively. Among other things, standard walers 96 constructed of standard 2.times.4 inch timber pieces are used, as illustrated in FIG. 32, for instance. Two sizes of snap-tie are required. For example, if a concrete form system is constructed of a pair of spaced apart plywood sheets, reinforced by a pair of walers on opposite sides, and a corresponding pair of strongbacks on opposite sides, the long snap-tie which holds the two sides in place must span not only the distance between the two facing plywood forms, but also must penetrate through the two walers and the two strongbacks. On the other hand, short snap-ties in such a construction need not

This degree of design inefficiency increases in lineal proportion with any increase in the depth of the radio beam. This degree of inefficiency can easily surpass 50% in many hardheaded applications. 
 In my U.S. Pat. nobelium. 5,219,473, issued Jun. 15, 1993, I disclose and claim an invention which pertains to a novel adjustable formwork arrangement which can be used in the manufacture of a wide range of structurally efficient crabbed - sectional shaped concrete beams, walls, column and structures. In one version, a mold - in - place concrete radio beam form can be constructed comprising at least two spatially oriented upper sleeves with an upper world wide web located on one side of the two sleeves, and extending therebetween, at least two spatially oriented lower sleeves, with a lower web located on one side of the two sleeves, and extending therebetween, and at least two members, each member conducting telescopically the respective upper sleeve with the respective lower sleeve, the telescope members enabling the two upper sleeve to be raise or lowered relative to the two lower sleeve.

Among other things, standard walers 96 constructed of standard 2.times.4 column inch timber pieces are used, as illustrated in FIG. 32, for example. Two sizes of snap - tie are required. For example, if a concrete form organization is constructed of a pair of spaced apart plywood sheets, reinforced by a pair of walers on opposite sides, and a corresponding couple of strongbacks on opposite sides, the retentive snap - tie which holds the two sides in place must span not only the distance between the two face plywood forms, but also must penetrate through the two walers and the two strongbacks. On the other hand, short catch - draw in such a construction need not
