The spring biases the socket against the multi-faceted bolt head end of the rod. The socket is placed over a concrete anchor such that the bolt head end of the rod is against the driven end of the concrete anchor bolt. The hammer drill is used in hammer mode to apply hammer pressure to the concrete anchor bolt through the concrete anchor driver tool.

The socket extends over the concrete anchor bolt and nut, and prevents the concrete anchor nut from spinning down the threads of the concrete anchor bolt. The socket also holds the concrete anchor nut in its preferred position to ensure maximum penetration of the concrete anchor shaft into the concrete while the concrete anchor is being driven into the concrete. Once the concrete anchor is installed, the hammer drill is switched to rotate mode and used to rotate the nut down the threads of the anchor shaft, and then to tighten the nut against the concrete.

Generally, a concrete anchor is installed in one of several ways. First a drill is used to drill a hole into the concrete or masonry material to receive the concrete anchor. A rotary hammer drill may be used in the drill rotate mode, with a drill bit to drill the hole in the concrete. Once the hole is drilled, the concrete anchor can be installed into the hole. The concrete anchor can be installed into the hole by manually hammering the concrete anchor bolt down into the hole.

This can be difficult and time-consuming manual process. In addition, manually hammering the concrete anchor bolt into the hole can damage the concrete anchor if the hammer accidentally strikes the concrete anchor nut or the concrete anchor bolt threads. It also means the installer needs several tools, including a hammer, a drill and a wrench.

The hammering process is performed in a kneeling position when the concrete anchor bolts are floor mounted. Thus, the installer is constantly changing tools, standing up, and then kneeling down, all of which takes time, energy, and can cause discomfort and injury.

Instead of using a hammer, a rotary hammer drill also known as a chipping drill or rotary chipping drill can be used to pound the concrete anchor bolt into the hole. This automates the hammer pounding. It does not, however, alleviate the need for several tools, or repeatedly alternating between standing and kneeling positions.

For threaded concrete anchor bolts with a rotatable anchor nut, the anchor nut must stay at the top of the threaded anchor bolt so the anchor bolt can be pushed as far as possible into the hole. Pounding and vibration tends to cause the nut to spin down the threaded concrete anchor bolt. Therefore, whether the installer is using a hammer or a rotary hammer drill to pound the concrete anchor bolt into the hole, the installer must periodically stop and rotate the anchor nut back to the top.

Once the threaded concrete anchor bolt is pounded all the way into the hole, a wrench is used to rotate the anchor nut down on the threaded concrete anchor bolt until the nut is against the concrete. This repeated use of the wrench to move the anchor nut back up to the top of the concrete anchor bolt, and then to tighten the concrete anchor nut on the anchor bolt once the concrete anchor bolt is installed in the hole, is awkward and time consuming.

Using a wrench adds to the number of tools needed to install the concrete anchor, and requires the installer to repeatedly alternate between a standing and kneeling position, or to repeatedly climb up and down a ladder if a ladder is used. It is, therefore, desirable to have a concrete anchor driver tool that holds the concrete anchor nut in position on the concrete anchor bolt while the concrete anchor bolt is being driven into the hole, and that also rotates and tightens the concrete anchor nut onto the concrete anchor bolt once the concrete anchor bolt has been driven in the concrete hole.

Additionally, when a rotary hammer drill is used to pound the concrete anchor bolt into the hole, it is difficult to hold the rotary hammer drill bit or other shaft device used to pound the concrete anchor bolt against the top of the concrete anchor bolt.

The drill bit tends to slip off the concrete anchor bolt and may also damage the top of the concrete anchor bolt. It is desirable to have a tool that secures the pounding end of the rotary hammer drill against the driven end of the concrete anchor bolt.

It is also desirable to have a concrete anchor driver tool that does not damage the concrete anchor during installation, that requires a minimum number of tools during installation of the concrete anchor, and that can be used easily in any installation position without repeated kneeling or ladder climbing. In embodiments of the disclosed invention, a rotary hammer drill is used in the drill rotate mode, with a drill bit, to drill holes in concrete. The concrete anchors are then placed into the holes.

The drill bit of the rotary hammer drill is then replaced with the disclosed anchor driver tool. The rotary hammer drill uses the rod of the anchor driver tool to apply hammer pressure to the concrete anchor bolt. The rotary hammer drill is used in the hammer mode to push the concrete anchor bolt into the concrete. The socket of the disclosed anchor driver tool holds the nut of the concrete anchor from rotating, so it does not move down on the concrete anchor bolt.

Once the socket end of the socket hits concrete, continued hammer pressure will compress the spring and allow the concrete anchor bolt to be pushed deeper into the hole. Once the concrete anchor bolt is pushed as far as possible into hole, the rotary hammer drill is switched to drill rotate mode.

The rotary hammer drill rotates the rod of the concrete anchor driver tool, which rotates the bolt head end of the rod. Rotating the bolt head of the rod rotates the socket, which in turn rotates the nut down the concrete anchor bolt and tightens the nut against the concrete. It is to be understood that although the use of a rotary hammer drill is discussed in this document, any tool may be used that couples to the shank end of a drill bit and possesses both rotation and pounding hammering or chipping capabilities.

One of skill in the art will understand that rotary hammer drills are often called by other names and there any numerous types of tools which can both rotate a drill bit and use a bit to pound or chip. Any tool that couples to the shank end of the concrete anchor driver tool disclosed herein which can both rotate the concrete anchor driver tool and pound, chip, or hammer with the concrete anchor driver tool is suitable.

While the concrete anchor driver tool is used in hammer mode, the bolt head end of the rod does not rotate, which prevents the socket from rotating. The socket holds the concrete anchor driver nut from rotating, which prevents the concrete anchor nut from moving down the concrete anchor bolt during pounding of the concrete anchor bolt into the hole. The bolt head end of the concrete anchor driver tool rod rotates the socket when the anchor driver tool is used in the rotate mode.

The socket can slide up and down the rod and rotate the concrete anchor nut to install the nut onto the concrete anchor bolt. Thus, with the disclosed concrete anchor driver tool, the socket prevents the concrete anchor nut from spinning down the threads of the concrete anchor bolt, and holds the concrete anchor nut in its preferred position to ensure maximum penetration of the concrete anchor bolt into the concrete. The disclosed concrete anchor driver tool protects the concrete anchor assembly, including both the concrete anchor nut and the concrete anchor bolt threads from damage during installation, and facilitates a perfect hammer strike to the concrete anchor head, preventing the concrete anchor bolt from bending.

The disclosed concrete anchor driver tool eliminates the need for a hammer and a wrench or ratchet wrench, minimizing the number of tools required for concrete anchor installation. The disclosed concrete anchor driver tool eliminates the need for kneeling during installation of concrete anchors in the floor, and provides for easy installation of concrete anchors in walls and overhead installations.

In the first embodiment, a driver tool 10 for a power hammer apparatus 12 is provided for setting an anchor 14 into a well 16 , such as in concrete material The driver tool 10 includes a power-hammer-attachment end 18 , a riser portion 20 connected to the power-hammer-attachment end 18 , and an anchor setting end 22 connected to the riser portion The power-hammer-attachment end 18 , the riser portion 20 , and the anchor setting end 22 are arranged along a common longitudinal axis 24 and can be formed as a unified integrated structure.

The riser portion 20 includes a hand grip area With special reference to FIGS. The internal anchor diameter 32 is greater than the external setting-end diameter The anchor 14 has an internal anchor depth 34 from anchor top to a top of a fully driven-in movable internal wedge spreader portion The anchor setting end 22 has a longitudinal setting-end length 35 that is greater than or equal to the internal anchor depth As shown in the embodiment of the invention in FIGS.

Use of either embodiment of the invention is shown in FIGS. More specifically, a portion of concrete material [] 40 is selected.

A well 16 is drilled in the concrete material 40 by using a drill bit not shown that is connected to the power hammer apparatus 12 by the chuck After the well 16 has been drilled, the drill bit is removed, and the driver tool 10 of the invention is connected to the power hammer apparatus 12 using the chuck Then, a non-deformed anchor [] 14 , shown in FIG.

The anchor 14 is a well known tubular anchor which can be a Power's shell for concrete and includes an internally threaded top tubular portion for receiving a complimentary threaded anchor bolt, bottom wedge portions 44 extending below the internally threaded top portion, and a movable internal wedge spreader portion 28 that is initially present in the top tubular portion but is later driven downward to spread out the bottom wedge portions After the non-deformed anchor [] 14 has been inserted into the well 16 , the anchor setting end 22 of the driver tool 10 is inserted into the anchor 14 , as shown in FIG.

As the anchor setting end 22 reciprocates up and down, the anchor setting end 22 hammers down the movable internal wedge spreader portion 28 deeper into the anchor This spreading action causes the bottom wedge portions 44 to dig into the walls of the well 16 in the concrete material 40 and to securely set the anchor 14 in the concrete material Stated differently, the anchor 14 is firmly fixed or anchored in the well 16 in the concrete material Then, the anchor setting end 22 of the driver tool 10 is removed from the anchor 14 , as shown in FIG.
