Description
TECHNICAL FIELD
[0001] The present invention relates to an anchor bolt hole
cleaning device suitable for cleaning cutting powder, etc. in an
anchor bolt hole.
BACKGROUND ART
[0002] In the case of fixing a device or the like on a concrete
surface, an anchor bolt hole is drilled on the concrete surface
using a vibrating drill or the like, and an anchor bolt is planted
in the anchor bolt hole. Thus, the device or the like is fixed on
the concrete surface.
[0003] There are so-called a resin anchor and a mortar anchor, in
which the anchor bolt is planted in the anchor bolt hole by an
adhesive force of resin or mortar filled between the anchor bolt
hole and the anchor bolt. In the present DESCRIPTION and CLAIMS,
these anchors may be collectively and simply called "resin
anchor".
[0004] In the case of the resin anchor, if there are cutting powder
and dust inside the anchor bolt hole (on an inner peripheral
surface and a bottom portion), a resistance of the anchor bolt to a
pull-out force deteriorates significantly.
[0005] Therefore, it is necessary that cutting powder, etc. do not
remain in the drilled anchor bolt hole, that is, it is necessary
that foreign matters (simply referred to as "cutting powder" in the
present DESCRIPTION and CLAIMS) such as cutting powder do not get
in between the anchor bolt hole and an outer peripheral surface of
the anchor bolt.
[0006] On this account, various anchor bolt hole cleaning devices
have been provided. Specifically, provided is a device which
scrapes out cutting powder, etc. by inserting into the drilled
anchor bolt hole a rod-like cleaning tool with a brush disposed on
its periphery (see Patent Document 1). Moreover, provided is a
device which scrapes out cutting powder, etc., adhered to the inner
peripheral surface of the anchor bolt hole, by a brush of a
cleaning tool which is made by disposing the brush on a periphery
of a core rod and on an upper end portion of which a cover is
formed, and suctions the scraped cutting powder from a suction
opening (see Patent Document 2).

DISCLOSURE OF THE INVENTION
Problems to be Solved by the Invention
[0009] However, although the device described in Patent Document 1
excels in that its configuration is simple, it cannot adequately
scrape out fine cutting powder, especially fine cutting powder
accumulated on the bottom portion.
[0010] Moreover, although the device described in Patent Document 2
can suction fine cutting powder from the suction opening, it is
difficult to scrape out comparatively large cutting powder
accumulated on the bottom portion by its brush or suctioning.
[0011] In view of these circumstances, an object of the present
inventor is to provide an anchor bolt hole cleaning device which
has a simple configuration, can scrape out cutting powder adhered
to the inner peripheral surface of the anchor bolt hole, and can
also effectively scrape out both fine and comparatively large
cutting powder accumulated on the bottom portion.
Means for Solving the Problems
[0012] The above object of the present invention can be achieved by
the anchor bolt hole cleaning device having the following
configuration.
[0013] An anchor bolt hole cleaning device according to the present
invention is provided with a brush on a peripheral portion thereof
and is capable of cleaning cutting powder adhered to a hole inner
peripheral surface, the anchor bolt hole cleaning device comprises
a suction nozzle which is able to be inserted into an anchor bolt
hole to suction the cutting powder, the suction nozzle includes a
main body that is a tubular body, a suction opening formed at a tip
end portion of the main body, and an exhaust opening which is
formed at a base end portion of the main body to be connected to a
tip end of a suction hose whose base end is connected to a suction
opening of a suction device, and the brush is disposed on an outer
peripheral surface of the main body.
[0014] In accordance with the anchor bolt hole cleaning device
according to the present invention having the above-described
configuration, the cutting powder adhered to the inner peripheral
surface of the anchor bolt hole can be scraped and dropped to the
bottom portion side by the brush disposed on the outer peripheral
surface of the main body of the suction nozzle inserted into the
anchor bolt hole such that the tip end of the suction nozzle faces
the bottom side of the hole, and the scraped cutting powder and the
cutting powder accumulated on the bottom portion of the hole can be
suctioned toward the suction device side from the suction opening
formed at the tip end portion of the suction nozzle.
[0015] Therefore, the cutting powder can be effectively removed
from the anchor bolt hole.
[0016] In addition, a conventional case requires three steps of
suctioning the cutting powder by the suction nozzle after the
drilling of the anchor bolt hole, scraping and dropping the cutting
powder adhered to the inner peripheral surface of the hole, and
again suctioning the scraped cutting powder by the suction nozzle.
However, in accordance with the anchor bolt hole cleaning device
according to the present invention, all the cutting powder, etc. in
the hole is surely suctioned outside by so-called one-touch
cleaning in which the tip end of the suction nozzle is simply
inserted into the anchor bolt hole, and the cutting powder, etc.
adhered to the inner peripheral surface of the hole is scraped and
dropped by the brush disposed on the outer peripheral surface of
the main body. Therefore, the cleaning operation can be carried out
extremely effectively, some steps can be omitted, and a workload of
a worker can be reduced.
[0017] Moreover, in the anchor bolt hole cleaning device according
to the present invention, in a case where the suction opening is
formed at a tip end of the main body, the cutting powder, etc.
accumulated on the bottom portion of the hole can be effectively
suctioned outside from the suction opening since the suction
opening opens toward the bottom portion of the hole.
[0018] Further, in the anchor bolt hole cleaning device according
to the present invention, in a case where the brush is disposed on
the outer peripheral surface of the main body in a spiral manner,
the cutting powder adhered to the hole inner peripheral surface can
be effectively scraped and dropped on the bottom portion of the
hole by rotating the suction nozzle in the hole.
[0019] Furthermore, in the anchor bolt hole cleaning device
according to the present invention, even in a case where a
plurality of the brush having a ring shape are disposed at
different levels of height on the outer peripheral surface of the
main body, the cutting powder adhered to the inner peripheral
surface of the hole can be effectively scraped and dropped on the
bottom portion of the hole by moving the suction nozzle upward and
downward and can suction the cutting powder.
Effects of the Invention
[0020] In accordance with the anchor bolt hole cleaning device
according to the present invention having the above-described
configuration, it is possible to realize an anchor bolt hole
cleaning device which has a simple configuration, can scrape out
cutting powder adhered to the inner peripheral surface of the
anchor bolt hole, and can also effectively scrape out both fine and
comparatively large cutting powder accumulated on the bottom
portion.

BEST MODE FOR CARRYING OUT THE INVENTION
Embodiment 1
[0040] Hereinafter, an anchor bolt hole cleaning device according
to an embodiment of the present invention will be specifically
explained with reference to the drawings.
[0041] FIG. 1 is a side view showing the entire configuration of a
suction nozzle of the anchor bolt hole cleaning device according to
an embodiment of the present invention.
[0042] An anchor bolt hole cleaning device A according to the
embodiment of the present invention includes a suction nozzle B
shown in FIG. 1. The suction nozzle (hereinafter may be simply
referred to as "nozzle") B includes a main body 1 that is a tubular
body, and a brush 2 disposed on an outer peripheral surface 1S of
the main body 1 along a longitudinal direction.
[0043] At a tip end of the main body 1, a suction opening 1A is
formed, which opens obliquely with respect to the longitudinal
direction. At a base end of the main body 1, an exhaust opening 1B
is formed, which opens in a direction perpendicular to the
longitudinal direction. The main body 1 includes a base end portion
1C that is a straight tubular shape, and a portion 1L which extends
from a lower end 1e of the base end portion 1C to the suction
opening 1A below the lower end 1e and is a tapered tubular body
whose diameter gradually decreases in a downward direction.
[0044] Although the material of the suction nozzle B is not
especially limited, it is preferable to use plastic in light of
weight reduction and mass production at low cost.
[0045] As shown in FIG. 1, in Embodiment 1, the brush 2 is disposed
only at a lower end portion of the tapered tubular body of the main
body 1. However, the brush 2 may be disposed so as to extend up to
a position on the base end side above the position shown in FIG.
1.
[0046] Moreover, in Embodiment 1 shown in FIG. 1, the brush 2 is
disposed on the outer peripheral surface 1S of the main body 1 in a
spiral manner. As shown in FIG. 1, in the case of forming the main
body 1 with a mold or the like, the brush 2 may be directly
disposed on the outer peripheral surface 1S of the main body 1.
Alternatively, as shown in FIG. 2, in the case of integral molding,
a spiral groove 1D may be formed on the outer peripheral surface of
the main body 1, and then a band-like body 3 with the brush 2
disposed on its surface may be put in the groove 1D by adhesion,
fitting, or the like. This is preferable since the integral molding
of the main body 1 can be carried out easily.
[0047] When in use, a tip end of an accordion hose 5 is connected
to the exhaust opening 1B of the main body 1 as shown in FIG. 5,
and a base end of the hose 5 is connected to a suction opening 7a
of a suction device (a vacuum cleaner is used as the suction device
in Embodiment 1) 7 via a conventional hose 9.
[0048] As shown in FIG. 5, after drilling an anchor bolt hole 8
with a concrete drill or the like, the nozzle B is inserted in the
anchor bolt hole 8 such that the suction opening 1A is directed
toward the hole (the suction opening 1A is located on the lower end
side in FIG. 5). In this state, by turning on a switch of the
suction device 7, cutting powder, etc. in the anchor bolt hole 8 is
suctioned from the suction opening 1A. The cutting powder adhered
to an inner peripheral surface 8S of the anchor bolt hole 8 can be
scraped and dropped to the hole bottom portion from the inner
peripheral surface 8S of the hole by the brush 2 by causing the
nozzle B to move upward and downward, rotate, etc., if necessary,
and the scraped cutting powder, etc. is suctioned from the suction
opening 1A together with the cutting powder accumulated on the hole
bottom portion.
[0049] As a result, the cutting powder, etc. in the anchor bolt
hole 8 is effectively suctioned outside the hole from the suction
opening 1A through the exhaust opening 1B, and the cutting powder,
etc. do not remain in the hole.
[0050] Therefore, in a case where an anchor bolt (not shown) is
planted in the anchor bolt hole 8 in this state, and resin or
mortar is filled in a gap therebetween, a desired resistance to the
pull-out force can be obtained since there are no cutting powder
between the anchor bolt and the anchor bolt hole.
[0051] As described above, since all the cutting powder can be
quickly and easily suctioned from the anchor bolt hole 8, the
anchor bolt hole cleaning device is especially preferable in the
case of forming so-called chemical anchor or mortar anchor. To be
specific, in the case of the chemical anchor and the mortar anchor,
the presence or absence of the cutting powder, etc. remaining in
the anchor bolt hole 8 significantly affects the performance of the
filler, and also significantly affects the resistance of the anchor
bolt to the pull-out force. However, in the present anchor bolt
hole cleaning device A, since the cutting powder, etc. in the hole
are removed surely and effectively, the cutting powder does not mix
with the filler, the filler is effectively filled between the
anchor bolt hole 8 and the anchor bolt (not shown), thereby
obtaining the desired high resistance to the pull-out force.
Embodiment 2
[0052] As another embodiment regarding the nozzle B, as shown in
FIG. 4, ring-like brushes 2 may be disposed at different levels of
height on the outer peripheral surface 1S of the main body 1.
[0053] In the anchor bolt hole cleaning device shown in FIGS. 1, 2
and 4, the suction opening 1A opens obliquely with respect to the
longitudinal direction (see a direction of a central axis shown by
a chain line). However, as shown in FIG. 6, the suction opening 1A
may open so as to be perpendicular to the longitudinal direction.
In such a case, as shown in FIG. 7, some concave-convex portions
may be formed on an opening end surface 1a of the suction opening
1A so that the suction is effectively carried out even in a state
in which the suction opening 1A contacts the bottom surface, etc.
of the hole. Note that in FIGS. 6 and 7, the same reference numbers
are used to denote the same or corresponding components as in FIGS.
1, 2 and 4, and detailed explanations thereof are omitted.
[0054] Although the foregoing described that the cutting powder
adhered to the inner peripheral surface 8S of the hole is scraped
and dropped to the hole bottom portion by the brush 2, it goes
without saying that the brush 2 may scrape out the cutting powder
outside the anchor bolt hole 8 depending on the type of usage.
INDUSTRIAL APPLICABILITY
[0055] An anchor bolt hole cleaning device according to the present
invention can be used for, for example, cleaning an anchor bolt
hole, etc.
