Abstract

The forms disclosed herein are intended for use in making porch foundations. The form is especially suitable for use with precast wall design. The forms are made up of two generally right triangular shaped side members each having a hook at one side of each of the right angles, suitable to be hooked over an existing foundation wall. One end of the form adjacent one of the acute angles is suitable to rest on a footing that supports the wall. A unique arrangement of the forms made up of an edge and clamp arrangement is provided which rigidly holds the side members together.

INVENTOR. To/vy CAR MILKOVICH BY lvaslc WALL FORM It is, accordingly, an object of the invention to provide an improved set of forms for an angle wall.

Another object of the invention is to provide a form that is simple in construction, economical to manufacture, and simple and efficient to use in making an angle wall.

Another object of the invention is to provide a set of improved forms for concrete.

With the above and other objects in view, the present invention consists of the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings and more particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportions, and minor details of construction without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings:

FIG. 1 is an isometric view partly in cross section of the form according to the invention.

FIG. 2 is a view partly in cross section showing a finished angle wall made using the forms.

FIG. 3 is a side view of the forms.

FIG. 4 is afront view of the form in assembled relation.

FIG. 5 is a front view of the end form separate from the other forms.

FIG. 6 is a cross-sectional view taken on line 6-6 of FIG. 5.

FIG. 7 is a side view of the endform shown in FIG. 5.

FIG. 8 is a partial enlarged view of the upper end of the forms taken from the upper right-hand side of FIG. 3.

FIG. 9 is an enlarged top view of the clamp arrangement.

FIG. 10 is an enlarged view of the clamp arrangement shown in FIG. 9.

FIG. 11 is an enlarged partial cross-sectional view taken on line 1l-ll ofFIG. 3.

Now with more particular reference to the drawings, particularly FIGS. 1, 3 and 11, the set of forms disclosed are made up of two side forms and end form as shown. The side forms each have the side panel 10 which may be laminated from several sheets of material such as plywood or a suitable material sold under the trade name PLIGLAZE." The panels 10 and 11 may have a total thickness of approximately three fourths of an inch.

The panels are generally in the shape of a right triangle blunted off at the acute angles, that is, having two side edges adjacent its right angle and one side edge opposite its right angle with the lower point and the forward point slightly flattened, as indicated. The panels have a border formed by the angle irons l6, l7, l8 and 28. These angle irons have a first leg 40 lying in coplanar relation with the outside surface of the sheet and an outwardly directed leg 41 extending outwardly therefrom lending lateral stiffness to the panels. The legs 40 of the angle 16 each have plates 33 welded to the leg 40 at 43 and this plate 33 is clamped to the panel 10 by means of bolts 44 which extend through holes in the panel 10 and through a hole 45 in the plate 33. A hole 42 is formed in the sheets 10 and this hole extends through the plate 33 and receives the rods 30. The rods 30 each have a head 47 on one end and a slot in the other end receives a tapered key 48. The head bears against the form on one side and the key 48 bears on the form on the other side thereby holding the forms from separating. Tubing 29 receives the rod 30. The ends of tubes 29 engage the inside surface of panels 10 and hold the forms outward in fixed spaced relation from each other.

The lower locater bracket assemblies 31 and 32 have the end plates welded to the ends of the tubes 29, see FIGS. 3, 4 and 7, and the rods 30 may be selectively positioned through any of the tubes 29 of the locater bracket assemblies so that the tube 29 of lower locater bracket assembly nearest the end form 50 will effectively adjust the position of the end form 50 relative to side panels 10. Thus, the side forms 51 and 52 receive the end form 50 between them. Tubes 29 hold the side panels 10 in spaced relation to each other and pins 30 restrain panels 10 from outward movement. The lower ends of

angles

16 and 17 are abutted against the plate 54 and welded to it and the plate 54, when the forms are in position for use, rests on the ledge 55 of the footing 26. Wall 25 rests on the footing 26 and is keyed thereto by the dovetail joint 57. The angle 18 extends outward toward wall 25 (see FIG. 1) beyond the angle 16 and rests on the ledge 59 while the angles l3, l4, and 15 are welded together to define a rectangular space which receives the upper end 60 of the wall. The gussets 27 reinforce the hooks formed by angles l3, l4 and 15.

It will be noted that the side forms are made of the sheets 10 framed by the

angles

16, 17, I8 and 21. The end forms, FIGS. 5, 6 and 7, are made of sheets attached to

edge reinforcing strips

67 and 68.

The hook 61, FIGS. 8, 9 and 10, is made up of

platelike hook parts

62 and 63, each having a laterally extending

web member

64 and 65 that have mating flanges which are slotted to receive the taper pin 66. The taper pin 66 may be driven to a suitable position to draw the

hooks

62 and 63 together to clamp the forms.

The end form member 50 may be made of laminated material, like the side panels, and has the

reinforcing strips

67 and 68. The

reinforcing strips

67 and 68 have the

plates

31 and 32 welded to them and tubes 29 welded to the plates so that when the pins 30 are inserted through any one of the tubes 29, the front form 50 will be held to the side forms and the side forms will be held in rigid relation with each other.

Before the concrete indicated at 34' is poured, reinforcing rods 70 may be formed in the wall 25 and extend outward, thus when the concrete 34' is poured and the fonns are removed, the porch wing wall 34 will be intact on the footing and wall 25.

The foregoing specification sets forth the invention in its preferred practical forms but the structure shown is capable of modification within a range of equivalents without departing from the invention which is to be understood is broadly novel as is commensurate with the appended claims.
