FASTENER INSTALLATION SYSTEM AND METHOD
FIELD OF THE INVENTION
[0001] The present invention relates to SDS drills, and more particularly
to
installing fasteners with SDS drills.
BACKGROUND OF THE INVENTION
[0002] In construction, one of the most common operations is to install
fasteners,
such as threaded fasteners, into a receiving surface such as concrete, metal,
wallboard,
and so on. The operation of installing fasteners generally requires a hole to
be drilled in
the receiving surface, an anchor to be installed in the drill hole, and then
the fastener be
installed in place in the anchor within the drill hole.
[0003] Often, threaded fasteners must be installed into a surface of hard
material,
such as a concrete wall or floor. In this case, it is common to use an SDS
type drill, as
is well known in the industry. SDS drills are rotary hammer drills that have a
chuck that
concurrently provides rotational and hammering motion for a retained drill
bit. The drill
bits have a pair of slots therein, and are inserted into and slidably retained
in a
specifically designed chuck system that allows for limited longitudinal
displacement of
the retained drill bit, as caused by a hammer-action mechanism. This specific
hammering action allows power to be directly, accurately and efficiently
transferred to
the drill bit.
[0004] Typically, it is undesirable to actually puncture the entire
thickness or
depth of the concrete walls or floors in order that they serve as a complete,
or nearly
complete, barrier. Therefore, the drill holes are over depth less than the
thickness or
CA 2994014 2018-02-05
depth of the concrete walls or floors. Accordingly, a nut or the like cannot
be engaged
onto the threaded lead end of the threaded fastener. In order to ensure that
the
threaded fastener is securely retained in the receiving surface, an anchor
such as a
wedge anchor is used.
[0005] In order to install a wedge anchor into a drill hole, it is
initially manually
inserted up part way into the drill hole. Subsequently, a hammer is used to
carefully tap
the wedge anchor into place. Unfortunately, this operation partly relies on
the skill and
strength of the worker, and also is fatiguing. Further, it is necessary to
carry around and
have immediately available a suitable hammer. Also, this operation can be
quite time-
consuming, especially considering that the worker must use the SDS drill and
the
hammer alternatingly, or in other words put down one tool and then pick up the
other
tool for every fastener/anchor pair that is to be installed.
[0006] It is an object of the present invention to provide a method of
installing a
fastener into a receiving surface.
[0007] It is an object of the present invention to provide a method of
installing a
fastener into a receiving surface, which receiving surface comprises a
concrete wall or a
concrete floor.
[0008] It is an object of the present invention to provide a method of
installing a
fastener into a receiving surface, which method employs an SDS drill.
[0009] It is an object of the present invention to provide a method of
installing a
fastener into a receiving surface, which method employs an SDS drill to drill
the drill
hole, employs an SDS drill to install the wedge anchor into the drill hole,
and employs
an SDS drill to turn the nut of the fastener to thereby advance the fastener
further into
the wedge anchor.
