US-20260125896-A1 - CONCRETE ANCHOR BODIES AND PLUGS

Abstract

An anchor for being embedded in concrete for attachment to a fastener to support a load comprises a plug having a main body portion extending upwardly from a base portion, the plug for being attached to a form board prior to pouring of concrete, the plug having an end portion disposed a distance from the form board; and an anchor body attached to the end portion. The plug is separable from the anchor body and removable from the concrete after the concrete is cured, leaving the anchor body embedded in the concrete, the plug providing a void in the concrete after removal to provide an access opening for a threaded portion of a fastener to attach to the anchor body.

Description

RELATED APPLICATIONS This is a divisional application of application Ser. No. 18/205,511, filed Jun. 3, 2023, which is a divisional application of application Ser. No. 16/889,894, filed Jun. 2, 2020, which is a divisional application of application Ser. No. 15/854,285, filed Dec. 26, 2017, which is a divisional application of application Ser. No. 15/429,345, filed Feb. 10, 2017, which is nonprovisional application of Provisional Application Ser. No. 62/294,231, filed Feb. 11, 2016, all of which afore-mentioned applications are hereby incorporated by reference. FIELD OF THE INVENTION The present invention is generally directed to an anchor embedded in a concrete structure for transferring load to the concrete structure, and particularly to placing the anchor within the concrete structure and be accessible for connection to a load. SUMMARY OF THE INVENTION The present invention provides an anchor for being embedded in concrete for attachment to a fastener to support a load, comprising a plug having a main body portion extending upwardly from a base portion, the plug for being attached to a form board prior to pouring of concrete, the plug having an end portion disposed a distance from the form board; and an anchor body attached to the end portion. The plug is separable from the anchor body and removable from the concrete after the concrete is cured, leaving the anchor body embedded in the concrete, the plug providing a void in the concrete after removal to provide an access opening for a threaded portion of a fastener to attach to the anchor body. The present invention also provides a plug for forming threads in concrete for attachment to a fastener to support a load, the plug for attachment to a form board prior to pouring of concrete, the plug including an end portion disposed a distance from the form board. The end portion is threaded for molding threads in the concrete. The plug is removable from the concrete after the concrete is cured, leaving a mold of the threads in the concrete, the plug providing a void in the concrete after removal from the concrete to provide an access opening for a threaded portion of a fastener to attach to the threads molded in the concrete. The present invention further provides an anchor for being embedded in concrete for attachment to a fastener to support a load, comprising a plug having a main body and a base attached to the main body, the base for attachment to a form board prior to pouring of concrete, the main body including an end portion disposed a distance from the form board; an anchor body attached to the end portion; the main body including an opening extending from the base to the end portion, the opening providing an access opening for a threaded portion of a fastener to attach to the anchor body embedded in the concrete after the base is removed after the concrete has cured. A plug for forming an impression in concrete for attachment to a fastener to support a load, the plug for attachment to a form board prior to pouring of concrete, the plug including an end portion disposed a distance from the form board; the end portion including a first circumferential groove and a removable ring partly disposed in the groove, the ring for molding a circular groove in the concrete. The plug is removable from the concrete after the concrete is cured, leaving a mold of the ring in the concrete, the plug providing a void in the concrete after removal to provide an access opening for a cylindrical body with a second circumferential groove with a locking ring to attach to the first circumferential groove in the concrete, the cylindrical body being attached to a fastener for securing a load.
