U.S. Cl. 249-27 9 Claims ABSTRACT OF THE DISCLOSURE A form assembly for molding a monolithic concrete building wherein the form panel for shaping the inside surface of the building roof is hingedly connected to the form panel which shapes the inside surface of the building wall, whereby the building roof may be formed with a selected pitch. A jack assembly is operatively connected to the roof panel for supporting the panel during the pouring of the concrete, the roof panel being removable from the jack allowing the jack to support the concrete roof during the curing of the concrete while rendering the form assembly available for use at another job site. 'Ihe form assembly also including a form panel for shaping the outside surface of the building wall, the upper end portion of this panel forming a cornice and a drip line adjacent the roof edge. The panels forming the building walls are supported in erected position by inserting the lower ends of the panels into channels carried by ground-engaging plates. Turn buckle tensioning devices are connected to opposite wall-forming panels for plumbing the panels prior to pouring of the concrete the frames for the windows and doors and electrical outlet boxes being adapted to be secured to the wall-forming panels prior to the pouring of the concrete, whereby they become embedded in the concrete walls of the finished building.

BACKGROUND OF THE INVENTION Heretofore, conventional concrete forms have been made by securing wooden planks or panels to studding or joists, each form being individually constructed for the particular configuration to be produced. After the concrete has set, the forms are stripped therefrom with the result that very little of the lumber can be used again. These forms are expensive to construct not only because of the cost of the lumber but also due to the labor required for constructing the forms and the considerable time involved in the tedious process of stripping the forms from the finished structure.

SUMMARY OF THE INVENTION To overcome the disadvantages experienced in conventional concrete forms, the form assembly of the present invention has been devised and comprises, essentially, a metal panel, for forming the inside surface of a building roof, hingedly connected to a metal panel which forms the inside surface of the building wall, whereby the building roof may be formed with a selected pitch.

A jack assembly is operatively connected to the roof panel for supporting the panel while the concrete is being poured; however, the roof panel is adapted to be removed from the jack assembly allowing the jack to support the concrete roof until the concrete is cured.

A metal panel for shaping the outside surface of the wall is positioned parallel to and spaced from the iirstmentioned wall-forming panel and is provided with outwardly aring portions at each end thereof to form a "ice cornice and drip line adjacent the edge of the roof and a thick wall portion adjacent the building footings.

The wall-forming panels are supported in erected position by means of upwardly facing channel members adapted to receive the lower end portions of the panels, the channels being carried by plates secured to the ground by suitable spikes driven therethrough.

Turnbuckle tensioning devices are connected to opposite wall-forming panels for aligning the panels prior to the pouring of the concrete, and the panels are adapted to temporarily hold the window and door frames and electrical outlet boxes prior to the pouring of the concrete whereby they become embedded in the walls of the nished building.

By the construction and arrangement of the assembly of the present invention, the form may be quickly and accurately erected for constructing a monolithic building, and then quickly disassembled for ready use on another location in the job site without the necessity of employing highly skilled labor. Furthermore, by using metallic panels in the forms, the assembly may be easily cleaned before being re-assembled; thus, the form assembly can be re-used for an extended period of time.

FIGURE 9 is a view taken along line 9-9 of FIG- URE 3.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings and more particularly to FIGURES 2 and 3, the form assembly of the present invention comprises a pair of wall-forming panels 1 and 2 hingedly connected as at 3 and 4 to a pair of roof-forming panels 5 and 6, respectively. Each of the wall-forming panels is fabricated by welding a flat metal sheet 1a and 2a to a reinforcing web structure, consisting of a plurality of interconnected vertical and horizontal channels 1b, 1c and 2b, 2c, respectively. Each of the roof panels is fabricated by welding a flat metal sheet 5a and 6a to longitudinally and transversely extending interconnected angle irons 5b, 5c and 6b, 6c, respectively.

The free ends of the roof panels are supported in operative position by means of a downwardly facing channel member 7 secured to angle irons 5b and 6b by suitable bolts 8, the depending legs of the channel member also being secured to the upper end of a conventional jack 9 by means of a bolt lil. By this construction and arrangement, when the concrete roof has set, but not sufiiciently to support its own weight, the free ends of the roof-forming panels 5 and 6 can be disconnected from the channel 7 allowing the panels to swing downwardly about hinge connections 3 and 4. The jack 9 and associated channels 7 will remain in place to support the roof until the concrete has been sufficiently cured whereby the form assembly may be moved to another job site.

As will be seen in FIGURES 3, 7 and S, each of the hinge connections 3 and 4 comprises a plurality of sleeves 10 welded to angle irons 5b and 6b, the ends of the sleeves abutting the ends of similar sleeves 11 Welded to angle irons 1d and 2d secured to the upper edge of sheets 1n and 2a, respectively. The sleeves are held in end-to-end abutting relationship 'by pintles 12 extending axially therethrough. A removable wooden strip 13, having an arcuate cross-section, is adapted to be placed on each of the hinge connections to not only prevent the concrete from flowing into the hinges but also to form a fillet between the concrete roof and wall of the building.

Referring to FIGURES 3, 4 and 5, each of the wallforming panels 1 and 2 are supported in the erection position by an upwardly facing channel 14 adapted to receive the lower edge of the respective panel. A pair of upwardly facing channels 15 are welded to and extend outwardly from channel 14 to thereby provide feet for channel 14, spikes 16 being driven through channels 15 to secure the assembly to the ground. In order to plumb the panels in a vertical plane when being erected, a plurality of turnbuckles 17 are provided. Each turnbuckle has a hook 18 connected to one end thereof which is adapted to be connected to a bracket 19 secured to the wall forming panels, the opposite end of the turnbuckle being secured to a guy wire 20 which extends diagonally between panels 1 and 2. Additional brackets 21 may also be secured to panels 1 and 2 to facilitate the handling of the panels or to provide a support for a scaffold.

The wall-forming panels 22 for the outer surface of the building wall are similar in construction to panels 1 and 2 and include a metal sheet 22a welded to vertical and horizontal interconnected channels 2211 and 22e. The upper portion of the panel is ared outwardly as at 22d to form a cornice for the building and a semi-cylindrical metal strip 23 is secured to the flared portion to form a drip line in the cornice of the building. The lower end of panel 22 is also outwardly flared as at 22e to form a thickened wall portion adjacent the building footings 24. Panels 22 are supported in erected position by channel members 25 and 26 which are identical in construction to channels 14 and 15 used to support wall-forming panels 1 and 2; the panels 22 also being pro-vided with handles or brackets 27.

The wall-forming panels 1 and 22 are held in spaced relation by means of a plurality of tie-rods 28 extending through and secured to the metal sheets 1a and 22a. As will be seen in FIGURE 9, each tie-rod comprises a bolt 28a which extends through a plastic sleeve 28b positioned between the opposed faces of sheets 1a and 22a, the bolt head engaging vertically extending channel 22b and the bolt nut 28C engaging the vertically extending channel 1b.

Before the wall-forming panels 22 are erected, various frames incident to the forming of doors, windows, etc. in the building to be constructed are adapted to be temporarily secured to panel 1. An illustrated example is shown in FIGURES 5 and 6 wherein an electrical outlet box 29 is secured to sheet 1a by suitable screws 30, the conventional electrical conduits 31 being connected to the electrical outlet box. By this construction and arrangement, when the form assembly is erected, the outlet box 29 will be positioned in the space between panels 1 and 22. When the form assembly is disassembled, the screws are removed and the box 29 remains embedded in the concrete; thus, allowing the conventional face or switch plate to be secured to the open side of the box. A similar arrangement is employed for the door frames and window frames of the building whereby the frames are temporarily mounted at a predetermined position in the space between the wall-forming panels 1 and 22 and become embedded in the concrete forming the walls of the building.

As will be seen in FIGURES 4 and 5, the length of the building wall will be determined by the number of wall-forming panels placed in end-to-end abutting relationship. To facilitate this arrangement, the vertical edges of. metal sheets 1a and 22a are provided with angle irons 1e and 22;, respectively, which are adapted to abut identical angle irons secured to the sheets of the adjacent wallforming panels 1 and 22', the joint formed by the abutting ends of the wall-fo-rming panels being overlapped by a pair of angle irons 14a secured to one end of support channel 14.

Referring to FIGURES l and 2, to construct a monolithic concrete building employing the form assembly of the present invention, suitable footings 32 having reinforcing rods 33 are first constructed, and the wall-forming panels 1, 2 and roof forming panels 5 and 6 are then erected and plumbed, as described hereinabove. Before both wall-forming panels 2, which form the building midpartition 34, are erected, a door frame 35 is temporarily secured to one of the panels. Other door and window frames and electrical outlet boxes are similarily secured to the panels 1 before the wall-forming panels 22 are erected. After the form assembly is properly erected, concrete is poured into the spaces Vbetween the wallforming panels and onto the roof forming panels to thereby form the front and rear walls 36 and 37 and roof 38 of the buiding. While the form assembly of the present invention has been described for constructing the front and rear Walls of the building, it will be appreciated by those skilled in the art that the side Walls of the building would be similarly formed by a suitably configured wall-forming panel constructed and arranged in accordance with the teachings of the present invention.

It will also be appreciated by those skilled in the art that by varying the heights of the wall-forming panels 1 and 2, the pitch of the roof can be correspondingly varied. Thus, to form a building with a at roof, panels 1 and 2 would have the same height, and to increase the pitch of the roof, panel 2 would have a greater height than panel 1.
