Abstract

Abstract Disclosed is a support for use in setting anchor bolts, and the like, in a monolithic poured concrete slab and the method of using the same. The support has a plate with a plurality of elongate legs extending from one side thereof. A wooden block is attached to the other side of the plate by nails extending through bores in the plate. A template is provided with a plurality of bores of a size to receive anchor bolt assemblies therein. The bores in the template have a spacial relationship according to the desired location of the anchor bolts in the slab. A central referencing hole is provided in the center of the template for releasably attaching the template to the upper surface of the wooden block during the installation procedure. To use the apparatus, the legs of the support are first embedded in the subsoil of the slab before the slab is cast. The upper surface of the block is leveled in position at a desired height. A nail is inserted in the wooden block at the theoretical center of the column. Concrete is poured in the area around the support. Next, the template is positioned with the referencing hole over the finishing nail and the anchor bolts are forced down into the concrete. The concrete is allowed to set and the template and wooden block are then removed leaving the anchor bolts in the correct position for attaching the column.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 97 words
An apparatus for use in setting anchor bolts in concrete, said apparatus comprising a support having a rigid plate, elongate legs extending transversely from one side of said plate for supporting said plate at an elevated position within a concrete form, a pierceable block releasably attached to said plate, a template releasably carrying a plurality of anchor bolts held in a predetermined spacial relationship, and means on said template for releasably attaching said template to said pierceable block whereby said anchor bolts are supported in a predetermined relationship in said form during the pouring of said concrete.
Claim 2
Independent Claim 97 words
An apparatus for use in setting anchor bolts in concrete, said apparatus comprising a support having a rigid plate, elongate legs extending transversely from one side of said plate for supporting said plate at an elevated position within a concrete form, a pierceable block releasably attached to said plate, a template releasably carrying a plurality of anchor bolts held in a predetermined spacial relationship, and means on said template for releasably attaching said template to said pierceable block whereby said anchor bolts are supported in a predetermined relationship in said form during the pouring of said concrete.
Claim 3
Dependent Claim 13 words
The apparatus of claim 1 wherein said pierceable block is formed from wood.
Claim 4
Dependent Claim 40 words
An apparatus as defined in claim 1 wherein said rigid plate has openings extending therethrough and wherein fasteners extend through said openings from said one side to engage said pierceable block to releasably attach said pierceable block to said plate.
Claim 5
Dependent Claim 31 words
The apparatus of claim 1 wherein at least three elongate legs extend from said plate and wherein said legs are of sufficient length to support said template at the desired height.
Claim 6
Dependent Claim 31 words
The apparatus of claim 1 wherein the means for releasably attaching said template comprises an opening in said template and a pin mounted in said block and extending through said opening.
Claim 7
Dependent Claim 38 words
The apparatus of claim 1 wherein said pierceable block comprises an elongate wooden member connected at its center to said plate and a form supported from said elongate member whereby a depression can be formed in said concrete.
Claim 8
Independent Claim 96 words
An apparatus for use in setting objects such as anchor bolts and forms in concrete, said apparatus comprising a support having a rigid plate, elongate legs extending transversely from one side of said plate for supporting said plate at an elevated position within a concrete form, a pierceable block releasably attached to said plate, a template carrying said objects in a predetermined spacial relationship, and means on said template for releasably attaching said template to said pierceable block whereby said objects are supported in a predetermined relationship in said form during the pouring of said concrete.
Claim 9
Independent Claim 96 words
An apparatus for use in setting objects such as anchor bolts and forms in concrete, said apparatus comprising a support having a rigid plate, elongate legs extending transversely from one side of said plate for supporting said plate at an elevated position within a concrete form, a pierceable block releasably attached to said plate, a template carrying said objects in a predetermined spacial relationship, and means on said template for releasably attaching said template to said pierceable block whereby said objects are supported in a predetermined relationship in said form during the pouring of said concrete.
