Description
SCREED FORM STAKE
The present invention pertains to the field of devices for use in concrete pouring operations. Particularly, the invention relates to screed form stakes used in concrete pouring operation to ensure that once the is poured it is smooth and level.
Screed and form stakes are conventionally used when pouring concrete in order to obtain the proper grade and to ensure a smooth level surface of the concrete once it has been poured. Form stakes are used to support concrete forms or barriers which are used along the outside of an area in which concrete is to be poured, so as to contain the poured concrete in that area. Screed stakes are used to support rods or bars, which are placed over large areas to ensure that the. concrete being poured is level and smooth.
On many smaller jobs individuals have taken to forming screed stakes from wooden scraps. These scraps are formed into stakes which are then used to support either concrete forms or screed rods/bars. This process is time consuming and often does not yield accurate results.
Alternatively, the use of complex screed systems is expensive, especially given the fact that, in many operations, screed stakes may permanently stay in the concrete once it has been poured. One solution to this problem used in the prior art was a multiple piece screed stake, part of which could be removed.
An example of this type of system is illustrated in U.S. Pat. Nos. 2,867,041 and 5,173,004. These systems, while effective, are more complex and costly than the screed system of the present invention. Further, the prior art systems are more complicated to use and generally require more than one individual to ensure proper placement of the stakes over a given area.
The present invention is A SCREEDIFORM STAKE SYSTEM comprised of a screedlform stake (10) and a stake driver (12). The screedlform stake (10) has a lower end, which is adapted for ground cutting by terminating in the shape of a point. The upper end of the screedlform stake (10) comprises a U-shaped cradle portion (14) adapted for receiving a screed rod or bar [(28) in FIG.
6]. The stake has two side flanges (16, 18), which together form the face portion of the stake. Holes (26) are drilled in each of the side flanges (16, 18) at predetermined positions. The holes (26) are for use in association with a concrete form and to assist in the proper placement of the stake in a screeding operation. A
central raised flange (20) is located on the face portion of the stake: The central flange (20) extends upwardly from the lower end of the stake where it is angled to cooperate with the pointed end of the face portion of the stake. The central flange (20) extends upwardly terminating in the raised U-shaped cradle portion (14) of the upper end of the stake (10). The stake may be of varying lengths, depending upon the depth of concrete to be poured. The stake driver (12) comprises a handle portion and a driver portion and is designed to mate with the screedlform stake (10) in use.
The presently preferred embodiment of the invention is disclosed in the following description and in the accompanying drawings.
In the drawings, FIG. 1 is a perspective view of the screed system of the present invention showing the screed/form stake and the stake driver in engaged relationship;
FIG. 2 is a front elevational view of the screed system of the present invention showing the screed/form stake and stake driver in engaged relationship;
FIG. 3 is an extended perspective view of the screed system of the present invention showing the screedlform stake and stake driver separated;
FIG. 4 is a rear view of the screedlform system of the present invention showing the screedlform stake and stake driver in engaged relationship;
FIG. 5 shows the screed/form stake of the present invention being used as a form stake; and FIG. 6 shows the screedlform stake of the present invention being used as a screed stake in association with screed bars or rods.
The Screed/Form Stake System of the present invention comprises a stake 10, which may function either as a screed stake or as a form stake, and a stake driver 12.
The ScreedlForm Stake 10 when being used in a screeding operation (as seen in FIG. 6) supports the bars or rods 28 that are used to determine the height of concrete when being poured over large areas. The bars or rods 28 are placed in the U-shaped cradle portion 14 at the upper end of the stake 10. In a screeding operation, the flanges on the stake are important in securing the stake in the ground. The side flanges 16, 18 prevent front to back movement while the raised center flange 20 prevents lateral movement. The side flanges 16 and 18 have rear surfaces 19 and 21. The central flange 20 is angled at the lower end so as to cooperate with the lower end of the face portion for facilitating entry into the ground. A first gusset 32 in the junction between the first side flange 16 and the central flange 20 and a second gusset 34 between the second side flange 18 and the central flange strengthen the three flanges. The gussets 32 and 34 also strengthen the connections between the cradle portion 14 anc~, the flanges 16, and 20.
When used as a form stake (as shown in FIG. 5) the stake supports barrier walls or forms 40, which contain the concrete as it is being poured in a given area. The stake is fastened to the form by fasteners 42 that pass through holes 26 in the side flanges 16, 18 which taken together form the face portion of the stake. These holes 26 are spaced at predetermined distances along the side flanges 16 and 18. The holes 26 allow the side flanges to be secured to a form.
They also help guide placement of the stake when being used as a screed stake.
The holes 26 receive conventional screws, nails or other conventional fasteners 42 and allow the stake to be securely fastened to the form 40.
In either use, the stake terminates at a point 44 at a lower end. The pointed lower portion 44 of the stake 10 facilitates entry of the stake into the ground.
The upper portion of the stake is formed into a U-shaped cradle portion 14 5 for receiving screed bars or rods 28, which are used as guides when pouring concrete over large areas. The U-shaped cradle portion 74 also receives the round portion 46 of the stake driver 12 when the stake 10 is being pounded into the ground. As seen in FIG. 3, the upper face "A" of the cradle portion 14 is of essentially the same size and shape as the portion marked "B" on the stake driver 12. This design allows for even distribution of the forces when the stake driver is being used to drive the stake into the ground. The cradle portion 14 is disposed on the face of the stake 10 and is formed of such a thickness so as to prevent breaking when being driven into the ground by the stake driver 12.
The stake driver 12 is designed to mate with the stake 10 while in use.
The upper end portion 48 of the stake driver 12 may be of any shape that allows for the use of a device (such as a hammer) to exert force on the stake driver and thereby pound the stake 10 into the ground. The round portion 30 of the stake driver is flush with the back of the stake driver 12 and extends outwardly from the front 50 of the driver. The stake driver 12 may also be designed having the round portion 30 extending outwardly from the back 49 and front 50 of the driver.
The round portion 30 of the driver must extend outwardly from at least one side of the stake driver because this portion of the driver serves two functions. First, it mates with the U-shaped cradle portion 14 of the stake 10 and the screed rod groove thereby aiding the driver's 12 function of forcing the stake 10 into the ground.
Second, the round portion 30 is designed to be of the same diameter as conventional screed rods or bars 28, thereby aiding in the level placement of the screed bars or rods on the stake once the stake has been driven into place.
The screed rod groove 52 has a groove axis 53 that is coaxial with the axis of the round portion 30 when the round portion is seated in the screed rod groove.
The groove axis 53 is perpendicular to the rear surface 19 and 21. Essentially, the outwardly extending round portion 30 has a screed rod elevation measuring surface 54 that serves as a platform for a transit and transit stick or other measuring system. The transit stick may be placed on the top measuring surface 54 of the outwardly extending round portion 30, which will be the same height as the stake 10 with a screed rod or bar 28 placed thereupon. Thus, the-proper height of the stake 10 and whether it is level, may be determined without the need for placement of the actual screed rods or bars 28 and may be accomplished by one individual.
The screedlform stake system may be made of any material suitable for withstanding the forces necessary to drive the stake 10 into the ground, including plastic, wood and metal, among others. Presently, it is believed that the most economical material for manufacturing the stake is plastic. However, other materials may be used so long as they are sufficiently strong to withstand the forces transmitted by the stake driver 12.
The disclosed embodiment is representative of a presently preferred form of the invention, but is intended to be illustrative rather than definitive thereof.
The invention is defined in the claims.

The holes (26) are for use in association with a concrete form and to assist in the proper placement of the stake in a screeding operation. A
central raised flange (20) is located on the face portion of the stake: The central flange (20) extends upwardly from the lower end of the stake where it is angled to cooperate with the pointed end of the face portion of the stake. The central flange (20) extends upwardly terminating in the raised U-shaped cradle portion (14) of the upper end of the stake (10). The stake may be of varying lengths, depending upon the depth of concrete to be poured. The stake driver (12) comprises a handle portion and a driver portion and is designed to mate with the screedlform stake (10) in use.
The presently preferred embodiment of the invention is disclosed in the following description and in the accompanying drawings.
In the drawings, FIG. 1 is a perspective view of the screed system of the present invention showing the screed/form stake and the stake driver in engaged relationship;
FIG. 2 is a front elevational view of the screed system of the present invention showing the screed/form stake and stake driver in engaged relationship;

FIG. 5 shows the screed/form stake of the present invention being used as a form stake; and FIG. 6 shows the screedlform stake of the present invention being used as a screed stake in association with screed bars or rods.
The Screed/Form Stake System of the present invention comprises a stake 10, which may function either as a screed stake or as a form stake, and a stake driver 12.
The ScreedlForm Stake 10 when being used in a screeding operation (as seen in FIG. 6) supports the bars or rods 28 that are used to determine the height of concrete when being poured over large areas. The bars or rods 28 are placed in the U-shaped cradle portion 14 at the upper end of the stake 10. In a screeding operation, the flanges on the stake are important in securing the stake in the ground. The side flanges 16, 18 prevent front to back movement while the raised center flange 20 prevents lateral movement. The side flanges 16 and 18 have rear surfaces 19 and 21. The central flange 20 is angled at the lower end so as to cooperate with the lower end of the face portion for facilitating entry into the ground. A first gusset 32 in the junction between the first side flange 16 and the central flange 20 and a second gusset 34 between the second side flange 18 and the central flange strengthen the three flanges. The gussets 32 and 34 also strengthen the connections between the cradle portion 14 anc~, the flanges 16, and 20.
When used as a form stake (as shown in FIG. 5) the stake supports barrier walls or forms 40, which contain the concrete as it is being poured in a given area. The stake is fastened to the form by fasteners 42 that pass through holes 26 in the side flanges 16, 18 which taken together form the face portion of the stake. These holes 26 are spaced at predetermined distances along the side flanges 16 and 18. The holes 26 allow the side flanges to be secured to a form.
They also help guide placement of the stake when being used as a screed stake.
The holes 26 receive conventional screws, nails or other conventional fasteners 42 and allow the stake to be securely fastened to the form 40.
In either use, the stake terminates at a point 44 at a lower end. The pointed lower portion 44 of the stake 10 facilitates entry of the stake into the ground.
The upper portion of the stake is formed into a U-shaped cradle portion 14 5 for receiving screed bars or rods 28, which are used as guides when pouring concrete over large areas. The U-shaped cradle portion 74 also receives the round portion 46 of the stake driver 12 when the stake 10 is being pounded into the ground. As seen in FIG. 3, the upper face "A" of the cradle portion 14 is of essentially the same size and shape as the portion marked "B" on the stake driver 12. This design allows for even distribution of the forces when the stake driver is being used to drive the stake into the ground. The cradle portion 14 is disposed on the face of the stake 10 and is formed of such a thickness so as to prevent breaking when being driven into the ground by the stake driver 12.
The stake driver 12 is designed to mate with the stake 10 while in use.
The upper end portion 48 of the stake driver 12 may be of any shape that allows for the use of a device (such as a hammer) to exert force on the stake driver and thereby pound the stake 10 into the ground. The round portion 30 of the stake driver is flush with the back of the stake driver 12 and extends outwardly from the front 50 of the driver. The stake driver 12 may also be designed having the round portion 30 extending outwardly from the back 49 and front 50 of the driver.
The round portion 30 of the driver must extend outwardly from at least one side of the stake driver because this portion of the driver serves two functions. First, it mates with the U-shaped cradle portion 14 of the stake 10 and the screed rod groove thereby aiding the driver's 12 function of forcing the stake 10 into the ground.
Second, the round portion 30 is designed to be of the same diameter as conventional screed rods or bars 28, thereby aiding in the level placement of the screed bars or rods on the stake once the stake has been driven into place.
The screed rod groove 52 has a groove axis 53 that is coaxial with the axis of the round portion 30 when the round portion is seated in the screed rod groove.
The groove axis 53 is perpendicular to the rear surface 19 and 21. Essentially, the outwardly extending round portion 30 has a screed rod elevation measuring surface 54 that serves as a platform for a transit and transit stick or other measuring system. The transit stick may be placed on the top measuring surface 54 of the outwardly extending round portion 30, which will be the same height as the stake 10 with a screed rod or bar 28 placed thereupon. Thus, the-proper height of the stake 10 and whether it is level, may be determined without the need for placement of the actual screed rods or bars 28 and may be accomplished by one individual.
The screedlform stake system may be made of any material suitable for withstanding the forces necessary to drive the stake 10 into the ground, including plastic, wood and metal, among others. Presently, it is believed that the most economical material for manufacturing the stake is plastic. However, other materials may be used so long as they are sufficiently strong to withstand the forces transmitted by the stake driver 12.
