' ATTORNEY.
Patented Oct. 13,, 1942 UNITED STATES PATENT OFFICE CONCRETE FOUNDATION WALL FORM James B. Oswald, BurlingameQCalif. Application March 22, 1941; Serial No. 384,689 4 Claims. (01. 25-131) This invention relates to building construction and particularly to a novel type of stakes for use in setting up forms for pouring concrete for foundations.
It is common in setting up forms for concrete foundations to employ wooden forms consisting of boards held in place by wooden stakes driven into the ground. When wood is used there is necessarily great Waste because the stakes can usually be used but once. Often in drivingthe stakes when one man holds the stake in one hand and attempts to drive it with the other, the hammerhead slips off of or misses the head of the stake and hits and injures the holding hand. When the forms are taken down after the poured concrete has set, the boarding is usually full of nails which constitute more or less of a menace by causing injury to workmen accidentally stepping upon a nail in a board.
By my invention not only may injuries of this sort be avoided, as later pointed out, but a form of stake is provided which can be used over and over again and thereby effect in the end a far greater saving than may be represented by the initial cost of the improved stakes.
In brief, the invention consists essentially of two complementary steel stakes and a spreader or spacer member; one of the stakes having a driving-stake portion and an offset portion to whichthe form boards are attached, and which offset portion provides a safety handle by which the stake can be held while the stake is being which that stake can safely be held and driven.
The stakes are perforated through which nails can be driven into the form boards.- When the forms have been filled with concrete and the latter has set, the stakes on their removal act as nail pullers to pull all the nails out of boards and leave both stakes and boards clean and ready for further use.
Having reference to the accompanying drawing:
Fig. 1 is a perspective of the complete assembly.
Fig. 2 is a vertical cross section of a wall and forms with the stakes in elevation.
Fig. 3 represents a modification of the invention adapted to form a wall which in turn is to support a veneer of brick.
Fig. 4 is a perspective View showing a special application of the invention where an anchor stake may be employed.
A and B represent a pair of complementary as to insure an even uniform wall.
stakes of metal preferably steel, and pointed so as to be driven into the ground at suitable distances apart depending on the specifications for wall thickness, height, etc.
For an ordinary dwelling calling for a foundation with a depth of sixteen inches, a top width of eight inches and a fourteen inch base, the stakes are usually made of steel bars of one half inch thickness by one and three quarter inches width and approximately three feet in length.
The outside stake A is plain except that at an appropriate point in its length it carries a purlin' bracket 2 adapted to support a purlin or aligning timber or bar 3 usually a 2 x 4; it being understood that these stakes A and B are arranged in pairs at frequent intervals, and it is necessary that they be properly lined up so To the top of one or the other of the stakes A and B, preferably stake A, is hinged a spreader bar 4 which has perforations or openings 5 to fit over stake B and maintain a predetermined distance between the stakes, say eight, ten or twelve inches more or less as the case may be.
The stake B is of unique construction as it is designed to adapt a form to a wall which is thicker at the base than at the top, and at the same time to economize in the use of concrete by not having the taper run all the way to the top as is customary where wooden stakes and Wooden forms are used.
Stake B has a driving portion B with a driving head extension 6 offset from which is an upwardly extending angular form portion 1. As seen in Fig. 1 each stake A and the offset portion I of stake B are provided with nail receiving perforations 8 by which the form boards 9 may be held in placeby driving nails inserted through these perforations into the boards.
1 In operation, a pair of these stakes A, B is driven into the ground at suitable intervals according to foundation plans.
Stake B is driven and guided by holding it by the offset portion 1 so that there is no danger of accident from the driving hammer.
Stake A is driven by the operator holding and guiding it by the spreader bar 4 and hitting on the upper driving end. Here again accidental injury from the hammer is avoided.
The spacing in parallelism or predetermined spaced relation of the stakes is accomplished by swinging the spreader bar 4 across to match over the companion stake B, as shown in Figs. 1 and 2.
The spreader bar is prevented from accidentally slipping up and off of stake B by a nail or like means fitting a corresponding perforation ll, Fig. 1, in bar B.
This is important particularly when it comes to placing and holding a sill [2 in place after the concrete l3 has been poured and when a block I4 is driven in on top of the sill and beneath the spreader bar to be sure that the sill has proper setting in the concrete.
The boards 9 which form the walls of the form are placed in position between the stakes either before or after the spreader bars are secured in place; the boards being nailed to the building.
, When the poured concrete is set and all is in readiness for dismantling the forms, it is only necessary to detach the spreader bars 4 from the stakes B and then using the spreader bars 4 as a lever, the stake A is pried loose from the boards 9. At the same time the stake acts as a nail puller to pull all its nails out of the boards and leave them free of nails and ready for re-use.
Stake B is pried loose from the boards on its side of the wall and at the same time removes all of its nails.
Among the several advantages pertinent to said invention and its use may be mentioned particularly: the saving in time, labor and material in setting up a foundation; saving in lumber; preventing wastage of lumber; saving of carpenter labor; saving of concrete; and saving of common labor in cleaning up; and minimizing accidents. The stakes are self cleaning and by acting as nail pullers salvage much lumber that would otherwise be rendered worthless except for firewood.
These stakes may be used repeatedly. Being prefabricated, they can be set as soon as received on a job without the delay of cutting stakes.
They, of course, can be made up for all uses and kinds of work and of lighter or heavier material according to size of form needed and the nature of the wall or foundation to be laid, and various sizes may be carried in stock for immediate call.
Fig. 4 illustrates an application of the invention where the foundation is to be laid on soil that is sandy or otherwise not firm. It has sometimes been found that in the use of these forms under such conditions, when the concrete is tamped into the form there is a tendency for the inclined shoulder portion of the stakes B to be lifted and withdrawn more or less from the ground, thereby throwing the form out of line.
To overcome this and since these stakes are necessarily aligned with one another according to foundation plans, a timber, such as a 2 x 4 of suitable length, is laid in the crotch formed by the upright portion of the stake B and the connecting inclined portion of the offset portion 1 and bridging several stakes B. A comparatively long anchor stake I l is then driven into the ground at suitable intervals between the stakes B; these anchor stakes I! having brackets l3 which clamp over the top of the timber l6 and prevent any upward movement of the timber I6 and, in turn, prevent any upward movement of the stakes B or of the forms of which they constitute a part.
Having thus described my invention, what I claim and desire to secure by Letters Patent is:
1. In a building form for concrete walls, the combination of a pair of metal stakes one of which has a driving portion with an angular offset form supporting portion having an upright extension parallel with and spaced from and extending above said driving portion, and a spreader and spacer bar carried by one of the stakes and engageable with the other to maintain the two stakes in proper relation, the stakes being provided with nail holes, and form members of wood nailed to the adjacent inner faces of the stakes, the nails passing through said nail holes.
2. A building stake comprising a metal bar.
which has a vertical section adapted to be driven into the ground, and an offset angular form supporting portion having a perforated upright extension to which form boards may be nailed to the stakes operable as nail pullers when the form is dismantled.
3. A concrete building form comprising in combination a pair of metal stakes one of which has a driving section and an offset integral angular form section, the opposed stake carrying a purlin bracket and a hinged spacer bar which contacts with the first stake to maintain the two stakes in spaced relation, both stakes having perforations, form boards supported by and between the stakes, nails passing through the perforations in the stakes and driven into the boards, said stakes acting when the form is dismantled as nail pullers to withdraw the nails from the boards.
4. A concrete building form comprising in combination a series of complementary stakes carrying form boards between them, the stakes on one side of the form having hook-shaped members, a timber laid in the open portions of said hooks, and anchor stakes connecting with said timber cooperating with the form stakes to hold the forms in position.
