Description

FIELD OF THE INVENTION

The present invention relates with the construction industry and more particularly pertains to a system and apparatus for the purpose of securing anchor bolts and rebar.

BACKGROUND OF THE INVENTION

One of the main concerns with respect to the construction of any home, building, or other man-made structure is the foundation upon which it is built. The relative strength or structural integrity of the foundation of a structure is acutely problematic in earthquake-prone areas. Poorly fashioned foundations can result in collapsed structures, lost property damage, injuries and even death. World-renowned cosmopolitan cities such as San Francisco have seen first-hand the devastating consequences of poorly built foundations.
Three of the cornerstones of any structural foundations is the anchor bolt, rebar, and concrete. One of the principal materials used in any construction project is concrete. Concrete is cost effective, moldable to virtually any shape desirable, scaleable, and simple to use and implement. Moreover, its intrinsic compressive strength is virtually unmatched.
However, whereas concrete can be compressed with great force, its tensile strength is only negligible by comparison. For this reason concrete must be compositely strengthened with steel reinforcing bars (or “rebar”) to resist tensile forces. The use of rebar acts as an internal skeleton by which the concrete can congeal around and bond with. Whereas anchor bolts are generally used to affix vertical walls with concrete slabs or foundations, or to affix horizontal framing to vertical concrete or masonry walls; rebar is generally used to connect concrete slabs, walls or foundations with other concrete elements.
The importance of anchor bolts may be most readily illustrated in an earthquake. In the event of an earthquake the vertical walls of a structure resisting the forces are swayed horizontally in-plane. This movement, in turn, creates great tension between the interface of the ends of the walls with the concrete. Without the anchor bolts the wall would quickly detach from the concrete slab and may potentially result in the collapse of the structure.
For these reasons, many building codes specify that anchor bolts must be positioned in its final place before pouring concrete. This leads to increased strength in the foundation. If anchor bolts are placed or positioned in the concrete after a pour, the strength of the resulting foundation is lessened quite considerably.
Unfortunately, in operation, the placement of anchor bolts before a pour of concrete is difficult and cumbersome. Strong winds, movement of heavy equipment, construction workers, etc. all risk moving or displacing anchor bolts which are tenuously disposed in their respective positions. Most often, these anchor bolts are positioned using flimsy tools which are bound to become undone by the forces mentioned above. And in particularly egregious cases, anchor bolts are placed into the concrete after the pour despite the contravention of the applicable building codes.
Therefore, what is clearly needed in the art is a system and apparatus to be used for securing anchor bolts in its final resting position before a concrete pour.
This placement should be secure and should be robust enough to withstand strong winds, etc. Moreover, the system should also provide a means to further buttress a structure by tying in its anchor bolts to the nearby rebar.

SUMMARY OF THE INVENTION

It is an object of the present invention to increase the foundational strength of a construction project by securing anchor bolts in its final resting position before a concrete pour. By reinforcing the slab or footing through its anchor bolts and rebar network the foundation may become tolerant of strong earthquakes.
Moreover, it is an object of the present invention to further reinforce the foundation by tying the anchor bars to the nearby rebar network. This reinforced foundation may prevent the anchor bolts from being pulled out of a slab in the event of a very strong earthquake.
