This application claims priority to U.S. provisional patent application No. 61/821,461 for REBAR SUPPORT filed on May 9, 2013, which is incorporated by reference for all that is disclosed therein.
BACKGROUNDIn many construction projects, concrete is laid as a flat slab. For example, the concrete may be laid as a slab for a driveway or as a floor of a building. Rebar is placed in a form in which the concrete is pored. The rebar provides additional structural integrity and to keep the concrete from cracking. In order to be fully effective, the rebar is usually centered in the slap of concrete. For example, a slap that is six inches deep would have a layer of rebar at a level of approximately three inches. In order to further the effectiveness of rebar, it is typically laid in a grid pattern. Rebar extending in a first direction is intersected perpendicularly by rebar extending in a second direction. After the rebar is laid properly, the concrete is poured over it to form the slab.
One problem with laying the rebar is the difficulty in maintaining the rebar at the correct height above the bottom of the slab. Supports may be used to hold the rebar at a specific height, but the rebar is very stiff, so any inconsistencies in the heights of the supports will cause the height of the rebar to be incorrect. The inconsistencies in height may also occur by the perpendicular rebar in that rebar extending in one direction lays on top of rebar extending in the perpendicular direction. Another problem with laying rebar is that the rebar is tied together in order to keep it flat an on a single plane, which can be very time consuming.
SUMMARYAn embodiment of a rebar securing device includes a first platform and a second platform. A frame is coupled to the first platform and the second platform. A first clamp is coupled to the frame, wherein a first rebar oriented along a first axis is receivable in the first clamp. A second clamp is coupled to the frame, wherein a second rebar oriented in a direction that is substantially parallel to the first axis is receivable the second clamp. A third clamp is located in the second platform, wherein a third rebar oriented along a second axis is receivable in the third clamp. A fourth clamp is located in the first platform, wherein a fourth rebar oriented along a third axis is receivable in the fourth clamp.
Rebar securing devices are disclosed herein. A rebar securing device enables rebar to be placed at different heights and does not require that intersecting sections of rebar be tied together. An example of a rebar securing device 100 (sometimes referred to herein simply as a securing device 100) is shown in
The securing device 100 may set on either the first surface 114 or the second surface 116 when in use. The securing device 100 as shown in
Additional reference is made to
Reference is made to
The curves in the first platform 110 and the second platform 112 serve to stabilize the securing device 100 by assuring that it has contacts with the ground surface on which it is located. As described above, the securing device 100 is able to be set on the ground surface, which is aided by the concave shape of the surfaces 114, 116. The securing device 100 is typically used in a construction site, which does not have an even ground surface, so the shape of the surfaces 114, 116 helps stabilize the securing device 100 on the ground surface. The stabilization of the securing device 100 is further enhanced when the securing device 100 is made of a resilient or flexible material, such as polypropylene. By having a flexible platform 110 and/or 112, the securing device 100 will always have multiple contact points with the ground surface, even when a load is applied to the securing device 100.
Referring again to
The securing device 100 offers two different configurations to support rebar as described above. A first configuration is shown in

Reference is made to
In some embodiments, the clamps 150, 156 are formed into the platforms 110, 112,
The securing device 100 may include a plurality of support structures in the frame 126 that support the rebar. Various support structures are disclosed herein, however, the securing device 100 may include other support structures and mechanisms. Referring to
The securing device 100 may also include truss-like structures that further support the clamps 130, 132. In the embodiments disclosed herein, a truss 174 is connected between the first platform 110 and the member 170 proximate the clamp 132. In some embodiments, the truss 174 contacts the clamp 132. A truss 176 is connected between the second platform 112 and the member 172 proximate the clamp 130. The truss 172 may be connected to the member 170 and/or the clamp 134. A truss 178 is connected between the member 170 proximate the clamp 132 and the member 172 proximate the clamp 130. The trusses described above serve to keep the members 170, 172 from bending and they offer further support for the clamps 130, 132.
While illustrative and presently preferred embodiments of the invention have been described in detail herein, it is to be understood that the inventive concepts may be otherwise variously embodied and employed and that the appended claims are intended to be construed to include such variations except insofar as limited by the prior art.
