Claim 8

C. second ground-engaging support means for the gridlike network and operatively connected thereto, the second ground-engaging support means comprising vertically adjustable elevating means secured to the bottom portion thereof and serving to raise and lower the support network between a first lower position, wherein the gridlike network is supported by the first ground-engaging support means and in which the decking form can be moved, and a second, raised position, wherein the gridlike network is supported by the second ground-engaging means in a stationary manner and the first support means is lifted from the support surface, said second ground-engaging support means further comprising a vertically extending girder movably connected at its upper portion to the gridlike network so as to permit moving the second ground-engaging support means out of contact with the ground, when the decking means is supported by the first ground-engaging means, the vertical girder of the second ground-engaging support means being a substantially hollow member, and the vertically adjustable elevating means comprising a hollow lower member telescopically interfitted, and relatively slidable, with the lower portion of the girder, and a jacking means having a base and a movable column means extending therefrom, the base being connected to one of the girder and the hollow lower member and the column means being connected to the other; and D. a substantially flat, thin plate resting upon and supported by the upper surfaces of the gridlike network and providing a continuous, flat and level, upper surface for supporting wet concrete.

Claim 9

The portable decking form of claim 1, wherein said movable means of the first ground-engaging support means are rolling means.

Claim 10

The portable decking form of claim 1, wherein said vertically extending girder is rotatably connected at its upper portion to the gridlike network.

Claim 11

The portable decking for of claim 1 wherein the lower member of said adjustable elevating means has a similar cross sectional configuration to the lower portion of the vertical girder.

Claim 12

The portable decking form of claim 1 wherein liquid flow damming means is attached to and extends upwardly from the upper surface of said plate, said damming means extending between opposite sides of said plate to limit the flow of poured concrete over the upper surface thereof.

Claim 13

The decking form of claim 1, wherein the gridlike network is formed of perpendicularly interconnecting lateral I-beams and longitudinal I-beams, the flanges of the lateral I-beams being removed from the end portions abutting against the side of a longitudinal beam, such that the ends of the web of the lateral beams are in contact with the webs of the longitudinal beams and the flanges of the lateral and longitudinal beams are in contact and substantially coplanar.

Claim 14

The portable decking form of claim 5, wherein the substantially flat, relatively thin plate has an upper surface having a generally L-shaped plan configuration.

Claim 15

The decking form of claim 7, wherein the damming means extends over that portion of the upper surface including the short leg of the L.

Claim 16

The portable decking form of claim 7, comprising in addition safety rail means secured to the edge of the gridlike network including the short leg of the L, extending perpendicularly upwardly therefrom.

Claim 17

The portable decking form of claim 9, comprising in addition adjusting means for adjusting the position of the damming means relative to the safety rail means.

Claim 18

The portable decking form of claim 1, wherein the first ground-engaging support means comprises a vertically elongated girder connected at its upper end to the gridlike network and having wheel means rotatably connected at its lower end, there being provided a plurality of such first support means to independently support and permit movement of the decking form.

Claim 19

The portable decking form of claim 1, wherein the vertically adjustable elevating means secured to each of the second ground-engaging support means are independently adjustable so as to permit maintaining the substantially flat plate horizontally level to overcome any unevenness or inclination of the supporting surface.

Claim 20

The portable decking form of claim 1, wherein the telescopically interfitted members each have a substantially rectangular cross-section, and wherein opposing faces of both the inner and the outer telescoping members have apertures therethrough which are aligned with one another and comprising in addition a fastening element inserted through and retained in the apertures in the inner and the outer telescoping members, thereby serving to fix the vertically adjustable elevating means into a desired vertical position.

Claim 21
