Abstract

A device, system, and method for holding reinforcing bars in fixed positions. A reinforcing bar securing device comprises a base and a securing means for securing the reinforcing bar to the base, which is configured to engage at least one rib of the reinforcing bar. The securing means may include a flange, a hinged member, or a flexible member, such as plastic, for example, configured to allow the reinforcing bar to enter the securing means in one direction and engage at least one rib on the reinforcing bar to prevent the reinforcing bar from withdrawing from the securing means. The flanges are configured to bend to press against the reinforcing bar as the ribs contact the flanges and as the reinforcing bar moves relative to the securing device as the reinforcing bar enters the surface. A system of the present invention is also presented for holding reinforcing bars in fixed positions. The system, in one embodiment, includes a first securing device for holding a first reinforcing bar in a fixed position in the surface and a second securing device for holding a second reinforcing bar at a predetermined position along the length of the first reinforcing bar. The second securing device may be configured with a lip to hold the second reinforcing bar proximate to the first reinforcing bar. A method of the present invention is also presented for holding a reinforcing bar in a fixed position in the surface using the reinforcing bar securing device.

Claims

1. A method of holding a reinforcing bar in a substantially fixed position in a surface comprising the steps of:

providing a reinforcing bar;

attaching a securing device to the reinforcing bar at a predetermined position, wherein the securing device includes a securing means for holding the reinforcing bar in a substantially fixed position, the securing means configured to engage a rib of the reinforcing bar;

wherein the securing device includes a base having a hole therethrough;

wherein the securing means is attached to the base and includes a channel in communication with the such that the reinforcing bar may be slid from the hole to the channel, wherein the channel is more narrow than the hole, such that the channel may engage with at least one rib;

wherein the channel is defined by a pair of contrapositioned flanges protruding from the base in a ramping configuration such that a least ramped portion of the contrapositioned flanges is disposed opposite the hole and a most ramped portion of the contrapositioned flanges is disposed adjacent the hole;

inserting the reinforcing bar into the surface until a bottom side of the securing device contacts the surface and prevents the reinforcing bar from entering further into the surface.

2. The method according to claim 1, wherein the flange ramps up at an angle between 0 and 60 degrees with respect to the base.

3. The method according to claim 1, wherein the flanges ramp up at an angle equal to an angle of the rib of the reinforcing bar with respect to the base.

4. The method according to claim 1, wherein the securing means is a flexible material configured to flex to allow the reinforcing bar to enter the securing means in one direction and configured to engage at least one rib on the reinforcing bar to prevent the reinforcing bar from withdrawing from the securing means.

5. The method according to claim 4, wherein the securing means is made of a material selected from the group consisting of plastic, rubber, ceramic, composite, and metal.

6. The method according to claim 1, wherein the flanges are configured to bend to press against the reinforcing bar as the ribs contact the flanges and as the reinforcing bar moves in an opposite direction with respect to the securing device.
