Concrete anchor bolt holder

Abstract

The present invention is a reusable anchor bolt holder having a generally annular column that detachably secures to and covers a concrete anchor bolt by a plurality of attachment members which secure to the threads of the anchor bolt. The annular column secures the anchor bolt in a vertically fixed position by means of a rotatably hinged wall support bracket that connects the annular column to a wooden retainer wall by being forcefully lowered onto the top surface of the wooden retainer wall. The wall support bracket has a spiked contact face, which when downward force is applied, is inserted and securely attached to the retainer wall, thereby keeping the anchor bolt in place. The wall support bracket can be removed from the retainer wall with an upward force, thereby rotating the contact portion of the bracket to a vertical position. The top of the annular column of the device mates with, or is formed to create an integrated safety cap of a larger surface area to prevent injury.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to concrete anchor bolt holders and positioners, more particularly to a new and improved anchor bolt holder with a hinged support bracket that allows for the device to be easily affixed to a retainer wall with a downward force, and removed with an upward force, further incorporating an anchor bolt safety cap to increase the safety of a worksite. [0003] 2. Description of the Prior Art [0004] In the field of construction, building structures are commonly placed on a concrete foundation. To increase structural stability, the frame of the structure is fixedly connected to the concrete foundation by anchor bolts. This ensures that the building structure will not shift with respect to the foundation. The use of anchor bolts are very common and oftentimes required in areas subject to natural disasters that might increase the chance of a building being shifted from its foundation such as in reg...

AI Technical Summary

Benefits of technology

[0012] The present invention is a reusable anchor bolt holder having a generally annular column that surrounds and covers the anchor bolt, and a vertically rotatable hinged wall support bracket which is temporarily engaged with the top surface of the wooden retainer wall. The wall support bracket has a spiked contact face, which when downward force is applied, is inserted and securely attached to the retainer wall, thereby keeping the anchor bolt in place. The wall support bracket can be removed from the retainer wall with an upward force, thereby rotating the contact portion of the bracket away from the wall. The top of the annular column of the device may be provided with a surface that mates with, or is formed to create an integrated safety cap of a larger surface area to prevent injury.

Problems solved by technology

Many problems occur with placing anchor bolts installed in this manner.

Often times, the anchor bolts are not aligned properly, as a result of the bolt being misaligned or moved out of alignment while pouring the concrete.

This creates serious problems as the building structure may not be able to be secured properly, and the process of installing a replacement bolt by drilling the concrete and using epoxy to fix another bolt in place is expensive and time consuming.

Unfortunately, the use of such a device is not economical or accurate.

The process is also time consuming as a worker is usually needed to construct the makeshift bolt holders at the work site, as such bolt holders cannot normally be used more than once.

The common problem with the above anchor bolt holders is the means for attachment of the bolt holder to the retainer wall.

This takes a long period of time, and in addition creates more dangerous waste in the form of used nails on the worksite which can cause injury to workers.

Another issue with anchor bolts is safety.

Anchor bolts can cause severe injury to an individual, as they are a tripping hazard, and may cause a serious impact injury if one were to fall on one due to the small surface area of the anchor bolt.

Another problem is the time consuming effort it takes to place caps on all of the anchor bolts, especially since all the anchor bolt holders usually must be removed first.

As much as an entire day may be lost at a given jobsite removing anchor bolt holders, and placing anchor bolt caps on each exposed anchor bolt.

The combination of any or all of the above mentioned problems can cause serious delay in projects as well as increase the amount of labor spent on a given project.
