Claims
1. A cover for encasing a threaded rod extending from structural
concrete, said cover comprising a cylindrical body having a length
at least as long as that portion of said threaded rod extending
from said structural concrete and a diameter larger than that of
said threaded rod.
2. In combination, a threaded rod and cover for encasing it
extending from structural concrete, said cover comprising a
cylindrical body having a length at least as long as that portion
of said threaded rod extending from said structural concrete.
3. The cover of claim 1 wherein said cylindrical body is color
coded representing differing dimensions.
4. A method of protecting threaded rods from structural concrete
comprising applying said threaded rods to and within forms,
applying a cover to the full length of said threaded rods that will
extend above said structural concrete after being applied to said
forms and applying said structural concrete to said forms.
5. In a method of protecting the threads of rods, said rods being
contained within and extending from structural concrete, the method
comprising applying said rods within frames and subsequently
pouring structural concrete to said frames to partially embed said
rods therein while exposing at least a threaded length of said
rods, the improvement comprising applying covers to the full length
of said rods anticipated to extend above said structural concrete
once poured, said covers characterized as each having a cylindrical
body and a diameter larger than that of the threaded rods, and
subsequently pouring said structural concrete within said frames.
Description
RELATED APPLICATIONS
[0001] This application is a continuation of and claims priority
from U.S. patent application Ser. No 12/054,594 filed on Mar. 25,
2008.
TECHNICAL FIELD
[0002] The present invention involves a cover and method for using
it for encasing a threaded rod to protect the threaded rod from
structural debris as it extends from structural concrete
BACKGROUND OF THE INVENTION
[0003] Virtually all structural concrete must include steel
threaded rods which enhance the structural integrity of the
concrete. In addition, it is routine to provide portions of such
threaded rods extending beyond the structural concrete mass for a
number of reasons including their use as anchors to affix the
structural concrete to adjacent structural elements. For example,
virtually all buildings begin with concrete foundations. Building
codes, particularly in areas prone to earthquakes, require these
foundations to be tied into the framework of the structure to
prevent it from slipping from the foundation during tremors. As
such, threaded rods are virtually always exposed at some point
during the construction process.
[0004] In practice, it has oftentimes been found to be highly
desirable to prevent debris, such as splashed concrete from fouling
the grooves of exposed threaded rods as the threaded rods, as noted
previously, are intended to tie into other structural members. When
structural concrete is formed, the threaded rods are first applied
within forms and the concrete then applied either directly from a
concrete mixing vehicle or by shoveling the concrete from an
intermediate container, such as a wheelbarrow In either instance,
the concrete oftentimes splashes and sticks to surfaces proximate
the pour. In anticipating this, workers oftentimes, in an attempt
to protect the threaded rod surface will apply tape, such as duct
tape to it only to be removed after the wet concrete has been
applied to its frame or mold Although the application of tape is
superior to leaving the threaded rod exposed to splashing concrete,
it is oftentimes difficult to remove the tape as splashed concrete
hardens about it. In addition, industrial tape, such as duct tape,
can oftentimes not be removed without leaving behind a glue-residue
which can be almost as unsatisfactory as the hardened concrete that
the tape was intended to isolate from the threaded rod surface.
[0005] It is thus an object of the present invention to provide a
means of protecting the threaded rod during the application of
structural concrete and during construction when debris might
otherwise foul it.
[0006] These and further objects will be more readily apparent when
considering the following disclosure and appended claims.
SUMMARY OF THE INVENTION
[0007] A cover for encasing threaded rod extending from concrete.
The cover comprises a cylindrical body having a length at least as
long as that portion of the threaded rod from the structural
concrete surface having a diameter larger than that of the threaded
rod.
BRIEF DESCRIPTION OF THE FIGURES
[0008] FIG. 1 is a side plan view of the cover of the present
invention positioned to fit over threaded rod emanating from
structural concrete.
DETAILED DESCRIPTION OF THE INVENTION
[0009] As noted previously, there is an issue involving exposed
threaded rod emanating from structural concrete that must be dealt
with in the field. Specifically, there is the need to protect the
threaded rod from splashing concrete or other debris noting that
the threaded rod will oftentimes be used as a tie down for adjacent
framing and other structures.
[0010] Reference is first made to FIG. 1 showing a segment of
structural concrete 13 having threaded rod 12 emanate there from.
Threaded rod 12 is encased by cylindrical cover 10 having a length
l sufficient to fully encircle rod 12 throughout its entire length
as measured from the surface of structural concrete 13. The
cylindrical cover 10 is produced and made available on a work site
in fairly long standard lengths.
[0011] In employing the present invention cylindrical covet 10
resides over exposed rod 12. No longer does one have to concern
oneself with the rod being compromised by splashing concrete or
other debris and nor does one have to wrap rod 12 with tape or
other protecting membrane which is difficult not only to apply but
to remove. Also no longer does one have to apply a protective cap
atop the threaded rod as is current standard practice, leaving the
rod sides unprotected. One would merely slide cover 10 over
threaded rod 12. Once the concrete is poured cover 10 would simply
be withdrawn from threaded rod and inventoried for later use.
[0012] The cover is made of plastic and, as a preferred embodiment,
the cylindrical body can be color coded to represent differing
dimensions. Thus, those in the field could readily identify
standard dimensions from a parts bin without the need to measure
each cylinder prior to its use.
