skeleton domes comprised of rod sections The advantages of my construction consist in light weight, economical production,.easy assembly and removal, an openwork construction which is convenient for installation of water pipes, utility conduits, etc., and very convenient nesting for easy storage and transportation. Also,single domes serve for a complete span between main girders with"- out the necessity of lapping a plurality of domes between girders; and, in some cases,
without the necessity of intermediate supports. i l
v The annexed drawings and thefollowing description set forth in detail certain means exemplifying my invention such disclosed means constituting, however, but one of the various forms in whichthe principle of my I invention may be embodied. In said annexed drawings:

similar to that shown in Figures 6,7 and 8, but in which the height of the frame is materially greater;
Figures 12,13 and '14 are respectively a side elevation, a plan view and an end elevation of a further modified or truss type of form;-' M
Figure 15 is a perspective view illustrating the method "of using the truss type of form shown in Figures 12, 13 and 14;
Figure 16 is a cross-section through a partially completed floor in which the type of form shown in Figure 15 is being used; and
Figure 17' is a perspective view of an extra end frame used in the type of form shown in Figures 12, 13 and 14.
Referring to the annexed drawings in which the same parts are indicated by the.
same respective ordinals in the several views, the type of floorform shown in Figures 1, 2, 3. 4 and 5, is a skeleton frame comprised of upper longitudinal side rods 1, intermediate upper longitudinal rods 2 and lower longi tudinal side rodsv3 united'by spaced cross frame members 4 consisting each of upper horizontal sections 5 and outwardly. diverging and downwardly extending side sections 6. all as plainly shown inFig'ures 1, 2 and 3. The several'rod members are suitably secured togetherto form the complete skeleton frame, preferably by welding. The frames thus formed in suitable lengths "are mounted at their lower side edges upon planks 7, Figure 4-. the latter being supported at their ends upon girder forms '8, and also suitably supported intermediate their ends. the several skeleton frames being laterally so spaced and disposed as to form between the adj acent frame members 6 a channel 9 of dimensions suitable for the concrete floor ioist-12 which is desired. Reinforcing rods 11 for the joist 12 are positioned in thechannels 9 in any suitable manner well known to the art As a sup- 7 port for the concrete andto prevent the same being lost through the skeleton frame, water-,
proof paper. canvas. metal lath, thin metal sheets, or other suitable flexible material 10 which will take the form shape without any special shaping operation; ismounted upon the skeleton frames, this cover ng material 10 being extended over the open ends of each skeleton frame. The pouring of the concrete results in the fireproof floor 13 with concrete joist 12, shown in Figure 5. The openwork forms are then readily removable from below after the concrete is properly set. If conditions or the desired installation require, a covering material 10 is used which is preshaped to conform to the shape of the skeleton frame.
If it is desired to provide for a ceiling, flush with the concrete joist 12 or suspended, wire hangers 14 are suspended from the reinforcing rods 11 before the concrete is poured, from which wires 14: suitable metal mesh 21 is susended, after the skeleton forms are removed,
The modification of Figures 6, 7 and 8 consists in staggering the cross frame members 4 relative to the longitudinal side rods 1 and 3 so as to provide a series of frame members 15 secured to said rods 1 and 3 upon one side and staggered with a series of frame members 16 secured to said rods upon the other side, noted.
Referring particularlyto Figure 9,1 thereall as plainlyshownin the figures in show a rod so bent as to form the entire outer frame member of one of the forms shown in Figures 1. 2 and 3. This number thus comprises the two end cross frames 4: and the two lower longitudinal rods 3 all as one integral member, each end frame 4' being comprised of the cross member 5 and the pair of diverging side members 6, the lower end of one side member 6 of one frame end 4' being welded to the other end 17 of the original rod from which this outer frame member is made.
In Figure 9a there is shown a special form of intermediate cross frame member for the type of dome shown in Figures. 1, 2 and 3, which comprises two spaced cross members 5 eachhaving a pair of divergingdownwardly extending side members 20 these side members 20 of the two cross members 5 converging respectively toward each other, the whole being comprised of a single rod memberbent into the shape plainly shown in Figure 9a and the ends of which are welded together at 23. A skeleton frame comprised of the outer frame member shown in Figure 9 and a plurality of cross frame members,such as shown in Figure 9a, is illustrated in F igure 9?). ,7 i
In Figures 10 and 11, theopenwork frames are madeso deep that an additional pairof longitudinal side rods 18 is used, the same {being disposed between the staggered'members 15' and 16 and midway of the distance between the upper side rod 1 and the lower side rod 3.
Referring particularly to Figures 12, 13 and 14, the form of frame therein shown is a self-sustaining truss type such that no temporary supports between girder forms, such as the timbers 7, Figure 4., are required. This truss frame is provided with diagonal side strengthening members 20 disposed between each adjacent pair of side members 6 each cross frame 4 comprised of the upper horizontal member 5 and the pair of diverging side members 6 being provided withextending foot portions 19 which are of a lengthvso as to provide for a material lapping of' adjacent feet 19 when the forms are assembled as shown in Figure 15, preparatory to pouring the concrete. These extended portions 19 support the flexible covering material. 10. This truss frame of Figures 12, 13 and 141- is further braced and strengthened with additional end frame members 4 one of which is plainly shown in Figure 17, and which are duplicates of the normal cross frame members, so that each end of the frame is formed of two cross frame members.
In Figure 15 is illustrated the use of the truss type of dome as a removable form, provided a suspended ceiling is desired; and in Figure 16 is illustrated the use of this type of dome as a permanent form,,the wire mesh 21 being suspended by the tie wires 14 before heconcrete is poured.
Figures 1, 2, 6, 7, 9, 9b, 10, 12 and 13 show short lengths of forms or fragments of lengths, but it will be understood that these, forms can be made in any reasonable lengths. The lengthis preferably a multiple of the distance between two cross frames. The length is also usually sufficient to span the distance between two girders. Such a spanning length is the preferred construction in the case of the forms illustrated in Figures 1, 2, 3, 6, 7,8, 9?), 10 and 11, and would be the necessary construction in the case of the form illustrated in Figures 12, 13, let and 15.
