WALL FORM Fi1ed Jan.23, 1928 IN VEN TOR. I EDWARD 7. HA mow.
Patented Jan. 14,, 15930 Hits EDWARD T. HARROLD, OF BINGHAIVETON, NEW YORK, ASSIGNOR TO HOTCI-IKISS STEEL PRODUCTS COMPANY, OF BINGHAMTON, NEW YORK WALL FORM Application filed January 23, 1928.
My invention is an improvement upon that shown and described in Patent No. 1,588,229 dated June 8, 1926.
The primary object of my invention is to provide a wall form for use in constructlng concrete walls which can be set up or dismantled with ease and rapidity and the lower sections of which when set up may be removed and placed above the upper sections for continued use. 7
Another object of my invention is to provide a form of great simplicity in use, thereby reducing to a minimum the time and materials required in construction work of this character.
Still another object of my invention is to provide a novel and eflicient type of upright support for cooperating with the panels and the wall form.
Other objects and advantages in details of construction and arrangement of parts will be apparent as the description roceeds, reference now being had to the gures of the accompanying drawing wherein like reference numerals indicate like parts.
In the drawing:
Figure 1 is a detail perspective view of one corner of a wall form set up wherein my invention is used.
Figure 2 is a detail plan view illustrating the application of my improved upright suport. p Figure 3 is a detail perspective, partly in section, illustrating the cooperation between my improved upright support and the wall form panels.
Figure 4 is a detail plan view of the tie rod used in connection with my invention.
The reference numeral 1 indicates a base or surface upon which a wall 2 of concrete is to be built.
Mounted at suitably spaced intervals upon the basal are the upright supports 3. These upright supports are preferably made of heavy sheet metal, cold rolled or otherwise Serial No. 248,689.
pressed in the form of channel bars having their channel portions 4 facing inwardly and having their inner edges bent outwardly to form laterally projecting flanges 5 on either side. It will be understood of course that similar upright supports are positioned directly opposite these first named supports and spaced therefrom, the desired thickness of the wall to be formed. These oppositely positioned upright supports are held against inner or outer displacement by means of tie rods 6 connecting them. These tie rods 6 are provided adjacent their ends with notches 7 If the height of the wall to be built is greater than the length of a given set of upright supports, another set of such supports may be positioned on top of the first set as shown clearly in Figures 1 and 2, a spacing bar 9 being placed between the adjoining ends of such uprights for a purpose to be described,
Any desired or suitable means for bracing the sets of upright supports may be used such as for instance the I braces shown and clescribed in the above mentioned patent These braces form no part of this invention and have therefore not been shown for the sake of clearness.
Adapted to be supported between the adjacent upright supports in such manner as to provide a hollow wall form to receive the concrete mixture, are the panels 10. These panels are provided with outwardly projecting upper and lower flanges 11, which flanges are cutaway as at 12 at their ends. The ends of the panels 10 are bent outwardly as at 13 I and then parallel with the body of the panel as at 14 for engagement within the channel portion of the uprights 3, the portion 13 of the ends lying flat against the tie rods 6, and when the panels are inserted on each side of the upright supports, the tie rods 6 are thus maintained in their position in the center of the H slots 8, thus preventing their displacement. It will be understood that in setting up the wall form, the uprights 3 may be placed ;in properposition, spaced apart the distance of the length of the panels 10 and such panels then slid into position downwardlyfrom the .top of the uprights,or when an upright has been placed in position, the panels may have their ends hooked into the channel portion of the uprights and then swung into position whereupon the nest upright maybe moved into position for engaging the opposite ends of such panels. The upper and lower flanges 11 of the panels-provide supports for holding the panels in proper vertical alignment, one upon theother. The cut away portions 12 attheends of the flanges 11 overlie the flanges 5 of the uprights.
If a wall of considerable height is to be built, it isdesirable that after the lower portionof the wall has become set and hardened that the forms, that is the panels and uprights, for such lower portion be removed and moved to position higher up for a continuation ofthe construction. I have pro- Qvided means for permitting this, such means comprising a ,seriesof oppositely disposed notches 1 5 in the flanges 5 of the uprights 3. These notches '15 are positioned slightly below the adjoining flanges 11 of the panels. They are spaced below such flangesat a .distanceequal to the thickness of the spacing bars 9 Therefore, when it is desired to dismantle alower section dru wall form, the projecting ends 16 0f the tie rods 6 are clipped off so as not to interfere with the removal of the uprights, the spacing bar 9 is knocked out of position, whereupon the upright 3 may be lifted upwardly the distance of the thickness of such spacing bar to permit the notches 15 to register with the overlying ends ofthe flanges of the panels, whereupon the uprights may be freely withdrawn outwardly. The acent free ends ofthe panels 10 are then grasped and thepanels swung outwardly as shown in Figure 1, if the adacent upright has not yet been removed, and
v if such adjacentupright has been removed,
be then mounted on the top of the remaining panels and uprights, the spacing bars being again placed between the uprights as they are built one above the other. It will be observed that the uprights 3 are all provided with an additional set of spaced notches 1'? so that when the uprights are moved to a new position on to of those remaining in position, such notches 17 will, due to the spacing bars 9, come in properposition with relation to the flanges 11 of the panels, to permit removal of the uprights and panels in the manner just described, thereby rendering the uprights interchangeable.
Itwill be clear that byproviding this means of removing the uprights and panels, the for1 n may be very quickly dismantled either in whole or in part without disturbing the balance of the form, By this construction,
the necessity of removing the panels one by one by sliding them upwardly out of ,the
channeled uprights is eliminated with areal details o' tconstruction andoperation without departing from the spirit andscope of my invention. l do not limit myself, therefore,
to the exact structure herein shown anddescribed other than the appended claims.
ends engageable in said channel, flanges on said panels overlying said side flanges, and means for vertically moving said support to bring said notches into registry with said panel flanges whereby; said support may be removed to permit removal of said-panels.
3. A wall form comprising an upright support having a channel and'side flangeaspaced notches in said flanges, a spacer on topof said support and a duplicate upright support on sa-idspacer, spaced notchesill the side flanges of said supports, panels havingtheir ends engageable in the channels of said supports, flanges on said panels overlying said side flanges, and means whereby upon removal of said spacer, said lower support may be raised vertically to bring its notches into registry with said panel flanges to permit removal of said lower support and panels.
4. A wall form comprising an upright sup port having a channel and side .flanges, spaced notches in said flanges, a spacer on top of said support and a duplicate upright support on said spacer, spaced notches in the side flanges of said supports, panels having their ends engageable in the channels of said supports, flanges on said panels overlying said side flanges, and means whereby upon removal of said spacer, said lower support may be raised vertically to bring its notches into registry with said panel flanges to permit removal of said lower support and panels, said supports having an additional series of spaced notches whereby the supports may be interchanged and placed one upon the other.
