Concrete pier foundation anchor bolt support and chamfer form

Abstract

Embodiments of the Concrete Form include a form tube, chamfer disk, and one or more form cross-members. The form cross-members are comprised of a center pivot, two bolt guides, which are formed by the cross-members, and an optional clamp. The chamfer disk is a disk that sits atop of the form tube and forms side chamfers when placed upon the form tube when the concrete cures. The chamfer disk is a separate formed or molded piece that will sit on top of the tube form in order to form a chamfer in the concrete. The chanfer disk is a ring-shaped device with the chamfer formed in positive relief under the ring of the chamfer disk. The optional clamp can be used to hold any conduit, tube or any other item during the pour.

Claims

1. A concrete form comprised of a. a form tube; b. a chamfer disk which sits upon the form tube; c. one or more form cross-members which provide the necessary support for the concrete form; d. wherein the form cross-members are comprised of i. a center pivot which connects the cross-members, ii. two bolt guides which are formed by the cross-members, and iii. an optional clamp used to hold any conduit, tube or any other item during the pour; e. wherein the chamfer disk is a disk that sits atop of the form tube where the chamfer disk forms side chamfers that when placed upon the form tube causes chamfers to be formed in the concrete when it is poured; f. wherein the form cross-members are comprised of a cross-member edge i. wherein the cross-member edge serves as a support for the cross-member when placed on top of the form tube; and ii. wherein the cross-member edge is used in conjunction with the cross-member clamp, the chamfer disk, and a cross-member to secure the cross-member to the form tube.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(8) Embodiments of the Concrete Form 100 include a form tube 105, chamfer disk 101 and one or more form cross-members 102.

(9) The form cross-members 102 are comprised of a center pivot 103, two bolt guides 104, which are formed by the cross-members 102, and an optional clamp 401. The chamfer disk 101 is a disk that sits atop of the form tube 105. The chamfer disk 101 forms side chamfers 201 that when placed upon the form tube 105, causes chamfers to be formed in the concrete when it is poured. The form cross-members 102 are manufactured from steel and are approximately inch in thickness and approximately two (2) inches wide. The form cross-members 102 will be thicker towards the end of the cross-members 102 (the ends that rest on the circumference of the form) relative to the middle of the cross-members 102 to provide the necessary support for the Conrete Form 100 when in practice.

(10) The chamfer disk 101 is placed on top of the form tube 105 when in use. The chamfer in the concrete is formed by the chamfer disk 101 which is placed on top of the concrete form tube. The chamfer disk 101 is a separate formed or molded piece that will sit on top of the tube form in order to form a chamfer in the concrete. The chanfer disk 101 is a ring-shaped device with the chamfer formed in positive relief under the ring of the chamfer disk 101.

(11) The optional clamp 401 can be used to hold any conduit, tube or any other item during the pour. The bolt guides 104 will have two cross members with two bolt slots/guides per arm. This will give a total of four locations that an anchor bolt can be installed.

(12) The form cross-members 102 are comprised of a cross-member edge 602. The cross-member edge serves as a support for the cross-member when placed on top of the form tube 105. The cross-member edge 602 is used in conjunction with the cross-member clamp 601 , the chamfer disk 101, and a cross-member 102 to secure the cross-member to the form tube. The chamfer disk 101 is first placed atop of the form tube 105. Then the cross-member is engaged to the chamfer disk with the cross-member edge (see FIG. 6B). Lastly the cross-member is affixed to the chamfer disk 101 with the cross-member clamp 601 (see FIG. 6A).

(13) The form cross-members 102 form one or more bolt guides 104 that serves to maintain the position of anchor bolts as the concrete is cured. The anchor bolts 104 are set and then the concrete is poured into the form. Once the concrete cures, the Concrete Form 100 is removed leaving the bolts positioned correctly for the installation of the object to be mounted.

(14) The chamfer disk 101 allow the user to produce uniform chamfers on the side of the concrete. The user pours the concrete into the form 101 and fills the form 101. Once the concrete hardens sufficiently, the user can remove the chamfer disk exposing the formed chamfer on the concrete.

(15) The clamp 401 is an optional device that can be installed over the center pivot 103 with a fastener. The clamp 401 can be used to position and secure conduits, rebar, bolts, or any other object that needs to be placed in the hardening concrete. The user secures the object to be positioned with the clamp 401 and allows the concrete to harden thereby affixing the object in the concrete.

(16) An overlay template can also be affixed to the center pivot 103. The template can then be used to position conduits, rebar, bolts, or any other object that needs to be placed in the hardening concrete at a specific location. By way of an example, a bolt that is used to secure a light fixture or pole must be placed over bolts embedded in the concrete.
