Abstract
An adjustable concrete form support bracket for bracing a concrete form. The adjustable concrete form bracket includes a body, a stake receiving member, and an interconnecting means for adjustably coupling the body and the stake receiving member together. The body is attachable to a concrete form, and the stake receiving member is constructed to receive a stake inserted into the ground to support the concrete form. The interconnecting means operates to adjust the lateral position of the stake receiving member to adjust the spacing between the concrete form and the stake, and thus, the horizontal or lateral position of the concrete form across the ground surface. In this manner, the stake does not need to be removed from the ground so permit this repositioning of the concrete form. The stake receiving member may include a stake securing means to permit grade adjustment of the concrete form.
Description
- The present invention relates generally to concrete form systems. More particularly, the present invention relates to an adjustable concrete form support bracket that is useful in positioning and retaining sections of concrete forms at a desired grade and lateral position.
- Flexible sheet metal or wood slat forms are quite often used for pouring concrete structures such as walkways, patios, driveways, etc. Conventionally, the forms are arranged and connected together to correspond to the desired shape of the final concrete structure. Frequently, stakes are driven into the ground around the outside perimeter of the form in an attempt to retain the position of the forms. Quite often, the stakes are not attached to the form sections and the sections are primarily supported by the ground surface. This method creates a problem if the grade of the supporting ground differs from the desired grade of the final concrete structure. To overcome this, certain form support brackets heretofore engage the stake and permit elevation adjustments of the form. However, at times it is desirable to not only position the elevation of the forms to the desired grade, but also adjusting the lateral position of the forms across the support surface may be required. Quite often, during construction of these forms, the spaced distance between two parallel forms along the length of the form from one end to the other may deviate from the desired spacing. The conventional method for correcting this, is to pull the stakes at the locations of variance, reposition the form sections, and then redrive the stakes into the ground. This process is very time consuming and may need to be repeated several times until each section is correctly positioned. As such, there is a need for an improved concrete form support bracket that is useful in positioning and retaining sections of concrete forms at a desired grade and lateral position.
- To overcome the problems discussed above, and other disadvantages inherent in the known types of concrete form systems and concrete form support brackets, the preferred embodiments of the present invention provides a concrete form support bracket of an improved construction that supports a concrete form and that permits elevation and lateral adjustment of a concrete form without requiring the pulling and redriving the securing stake.
- To achieve these and other advantages, in general, and in one aspect, a concrete form bracket attachable to a concrete form for supporting and positioning the form is provided. The concrete form bracket includes a body attachable to a concrete form so as to be at least partially disposed outwardly of an outward facing vertical surface of a concrete form; a stake receiving member; and an interconnecting means for adjustably connecting the stake receiving member to the body such that the stake receiving member is laterally positionable at any location toward and away from the outward facing vertical surface of the concrete form between an inward most position and an outward most position, whereby the lateral position of the concrete form can be adjusted relative to a stake that is secured to a ground surface and that is received by the stake receiving member.
- In general, in another aspect, a concrete form system is provided. The concrete form system includes a concrete form; a form bracket, the form bracket including a body attached to the concrete form so as to be at least partially disposed outwardly of an outward facing vertical surface of the concrete form; a stake receiving member adjustably attached to the body such that the stake receiving member is laterally positionable at any location toward and away from the outward facing vertical surface of the concrete form between an inward most position and an outward most position, whereby the lateral position of the concrete form can be adjusted relative to a stake that is secured to a ground surface and that is received by the stake receiving member.
- In general, in another aspect, a concrete form bracket for supporting and positioning a concrete form both in grade and laterally is provided. The concrete form bracket includes a body attachable to a concrete form so as to be at least partially disposed outwardly of an outward facing vertical surface of a concrete form; a stake receiving member adjustably attached to the body such that the stake receiving member is laterally positionable at any location toward and away from the outward facing vertical surface of the concrete form between an inward most position and an outward most position; and a stake securing bolt operably connected to the stake receiving member for selectively securing a stake to the stake receiving member, whereby the lateral position of the concrete form relative to a stake that is secured to a ground surface and that is received by the stake receiving member is adjusted by adjustment of the lateral position of the stake receiving member, and whereby the grade of the concrete form relative to the ground is adjusted by securing the stake receiving member to the stake at the desired grade by the stake securing bolt.

Theconcrete form 100 may be of other suitable materials, such as, but not limited to metal and plastic. The concreteform support bracket 10 will be attached to theconcrete form 100 using an appropriate method for the material in which the concrete form is made of The concreteform support bracket 10 comprises abody 12, astake receiving member 14, and an interconnecting means 16 for adjustably coupling the body and the stake receiving member together. - With reference to
FIGS. 1-4 , thebody 12 is of a general C-shaped construction including twoside members back member 22 connected to and extending between each side member. Anattachment flange 24 extends generally perpendicular fromside member 18 opposite of theback member 22, and anattachment flange 26 extends generally perpendicular fromside member 20 opposite ofback member 22. Thebody 12 may be produced rapidly and inexpensively by roll forming methods of metal sheet material. Alternatively, thebody 12 may be formed from separate pieces of steel plate welded together or may be cast formed or molded from other suitable materials. Theflanges bracing surface 28 against theconcrete form 100. Thebracing surface 28 is generally placed flush against the outward facingvertical surface 104 of theconcrete form 100. Preferably, thebracing surface 28 is generally flat. A plurality ofapertures 30 on eachflange form support bracket 10 to be attached to theconcrete form 100 with screws, nails orother fasteners 106. Alternatively, the concreteform support bracket 10 may be attached to a metal concrete form by welding, or may be integrally molded to a plastic concrete form. - The
stake receiving member 14 provides a means for receiving thestake 108 that will hold theconcrete form 100 in place during forming of the concrete structure. Thestake receiving member 14 is positioned into a receivingarea 32 defined by theside members back member 22 of thebody 12. Thereceiving area 32 is generally elongated in a direction perpendicular to theback member 22 and is dimensioned to permit horizontal or lateral movement of thestake receiving member 14 towards and away from the back member. Thestake receiving member 14 can be constructed in any number of configurations so long as it securely, yet removably engages thestake 108. Thestake receiving member 14 may comprise ahollow tube 34 having an inner diameter corresponding to the outer diameter of thestake 108, and is of a sufficient length to hold a stake within it and to prevent the stake from pivoting within the stake receiving member. As shown, thetub 14 has a circular cross-section to correspond to the circular cross-section of thestake 108. Alternatively, the cross-section of thetube 34 may have another shape, such as square, rectangular or triangular to correspond to or otherwise accommodate stakes of other cross-sections. - The
stake receiving member 14 is adjustably attached to thebody 12 by theinterconnecting means 16, which permits the stake receiving member to be positioned at any location between an inner most and outer most position. The outer most position being the farthest from theback member 22 and the closest to thevertical surface 104 of theconcrete form 100. The inner most position being the closest to theback member 22 and the farthest from thevertical surface 104 of theconcrete form 100. In this manner, with theconcrete form 100 attached to the concreteform support bracket 10, which is held in place bystake 108, the lateral or horizontal position of the concrete form relative to the stake can be adjusted inwardly or outwardly by adjusting the position of thestake receiving member 14. Adjusting the position of thestake receiving member 14 towards the inner most position, as shown inFIG. 3 , increases the distance between thestake 108 and theform 100. Adjusting the position of thestake receiving member 14 towards the outer most position decreases the distance between thestake 108 and theform 100. Accordingly, the horizontal positioning of theform 100 across the ground surface can be adjusted without requiring removal of thestake 108 from the ground surface. - Referring to

Theopposite end 40 of theshaft 36 can be fitted with a handle, knob or formed to receive a separate driving tool, such as a wrench, such as shown. Alternatively, theshaft 36 and the hole may not be threaded, and a clamp, cam lock or the like may be provided to lock the shaft in position. - Additionally, the
stake receiving member 14 may include a stake securing means 42. The stake securing means 42 serves to hold thestake 108 in place once received by the stake receiving member. The stake securing means 42 operates to selectively engage thestake 108, such that the position of the stake in thestake receiving member 14 may be adjusted. In this manner, the elevation or grade of theconcrete form 100 may be adjusted by selectively raising or lowering the concreteform support bracket 10 on thestake 108. The stake securing means 42 may comprise one or more set screws or lockbolts 44 which are tightened against thestake 108. The one oremore lock bolts 44 may extend through alongitudinal slot 46 on therespective side member - A number of embodiments of the present invention have been described.
