unroll the steel net which has a big volume and big weight and is transferred in
the rolled state and to install over the entire portions of the back surface of the
falling rock preventing fence 100. Since the back surface of the support member
10 and the wire rope 20 are needed to be tied, respectively, much time is
needed for installation work, and the cost increases.
In addition, in the conventional falling rock preventing fence, since the
steel net is formed of one long steel net which has the same length as the entire
length of the falling rock preventing fence, when part of the steel net installed at
the backside of the falling rock preventing fence is damaged due to the falling
rocks or landslide, the maintenance is not easy.

member 10 inserted thereinto are fixed using a bolt.
The operations of the present invention will be described with reference
to Figures 2 and 13.
As shown in 2 through 13, when the steel net of the present invention is
installed, a plurality of support members 10 are vertically installed on the ground
at regular intervals. When the support members 10 are installed on the ground,
the rectangular groove 12 is oriented in the rear direction, so that the back side
in which the steel net 30 is installed is hidden, whereby the front side of the
same looks nice.
After a plurality of support members 10 are vertically installed on the
ground at regular intervals, the wire rope 20 passes through the rope through
holes 15 horizontally formed at the neighboring support members 10, and the
wire rope fixture 21 is connected with the end of the wire rope 20 passing
through the support member 10 installed at both ends. The bolt is provided to
the wire rope fixtures 21 , so that the wire rope 20 can be loosened or tightened
by tightening or loosening the bolt. At the initial work stage, it is needed to make
the wire rope 20 loosened, and after all steel nets are installed, it is needed to
make the wire rope 20 tightened by tightening the bolt of the wire rope fixture 21.
Two steel nets 30 are inserted into the rectangular 12 formed at the
support member 10, and the cover member 1 contacts with the rear surface of
the steel net 30 inserted into the rectangular groove 12 together with two groove
insertion portions 32, and the steel net 30 is fixed at the support member 10 by
engaging the fixing bolt 2 or the U bolt 4, and the upper and lower connection
portion 35 formed at the upper and lower portions of the steel net 30 are fixedly
engaged using a bolt, a rivet or a wire, so that the installation work of the
present invention is finished.
When the steel net according to the present invention is installed, as
shown in Figures 5, 6 and 7, the steel net 30 of the present invention may be
implemented based on the first, second and third embodiments. The installation
method is slightly different from each other. The installation state of each
embodiment will be described with reference to a corresponding drawing.
When the steel net 30 of the first embodiment of Figure 5 is installed, as
shown in Figure 8, the wire rope 20 is horizontally inserted into the rope through
hole 15 horizontally passing through the support member 10. The rope through
hole 15 is formed at both inner sides of the body 11 and the rectangular groove
12 and at the lateral side 14. When the rope through hole 15 formed at the
lateral portion 14 comes closer, and then the wire rope 20 passes through the
rope through hole 15, since the wire rope 20 is supported by the flat groove
portion 13, so that when rocks or steel net 30 fall down, the supporting force of
the wire rope 20 is enhanced.
The groove insertion portion 32 bent at the steel net 30 is inserted into
the rectangular groove 12 of the support member 10. The groove insertion
portion 32 of the steel net 30 inserted into the rectangular groove 12 is engaged
together with two groove insertion portions 32 positioned at both ends of two
steel nets 30 which are neighbor in the lateral direction.
The groove insertion portion 32 inserted into the rectangular groove 12 is
provided with the cut portion 33, so that it is inserted like surrounding the
previously installed wire rope 20. The cut portion 33 is thinner than the width or
thickness of the rectangular groove 12, so that a surplus space is formed
between two groove insertion portions 32. When the angular pipe 3 is inserted
into the above space, the thickness that two groove insertion portions 32 and
the angular pipe 3 are summed is matched with the width of the rectangular
groove 12, so that both ends of the steel net 30 are not movable in the
rectangular groove 12.
In this state, the fixing bolt 2 is inserted from the front center portion of
the support member 10 and passes through the bolt insertion hole 34 of the
groove insertion portion 32 inserted into the groove bottom portion 13 and the
rectangular groove 12 of the rectangular groove 12, and the angular pipe 3 and
the cover member 1 and is engaged with the backwardly protruded screw
portion and is fixing using the nut, so that the steel net 30 is fixed at the support
member 10. Continuously, the steel net 30 is inserted between the neighboring
support members 10 in the same manner, so that a plurality of steel nets 30 are
stacked in a vertical direction, which are formed in the rectangular plate shape
as high as the height of the support member 10.
The upper and lower connection portion 35 is formed at the upper and
lower ends of the stacked steel nets 30, so that the upper and lower connection
portion 35 is stacked in the vertical direction. The upper and lower connection
portions 35 are stably connected in such a manner that a bolt, a rivet or a wire
is inserted into the engaging hole 36 of the stacked upper and lower connection
portions 35. In this construction, when land slides or rocks fall or the steel net
30 is broken and falls down, since the upper and lower connection portions 35
are fixedly connected by the rivet, bolt or wire, the upper and lower steel nets
are not widened, and landslide or falling rocks do not penetrate in the forward
direction of the steel net 30.
The installation of the steel net according to the second embodiment of
Figure 6 will be described. It is nearly same as the installation of the first
embodiment of Figure 9, but in the second embodiment, the width of the groove
insertion portion 32 is half of the width of the rectangular groove 12. So, when
two groove insertion portions 32 are inserted into the rectangular groove 12, it is
tightly inserted therein without any movement. In this embodiment, it is not
needed to insert the angular pipe 3 which is provided in the first embodiment.
As two groove insertion portions 32 are tightly inserted into the
rectangular groove 12, the U bolt 4 is inserted from the front side of the support
member 10 and passes through the steel net 30, and the cover member 1
having the bolt insertion hole at both sides is contacted at the rear surface of
the steel net 30, and the screw portion of the U bolt 4 passes through the bolt
insertion hole of the cover member 1 and is engaged using the nut, so that the
steel net is installed at the support member 10.
Since the construction that the upper and lower connection portion 35 of
the steel nets 30 inserted and stacked between the support members 10 is fixed
using a bolt, a rivet or a wire is the same as the first embodiment, the detailed
description of the same will be omitted.
Figure 7 is a view of a construction that the steel net according to the
third embodiment of the present invention is installed at the support member 10.
As shown in Figures 10 and 11 , in the first embodiment, the constructions that
the wire rope 20 is installed at the support member 10, and two groove insertion
portions 32 are inserted into the rectangular groove 12, and the angular pipe 3
is inserted between two groove insertion portions 32 inserted into the
rectangular groove 12 are the same as the first embodiment of the present
invention.
After the angular pipe 3 is inserted, the cover member 1 is contacted with
the rear end of the steel net 30 inserted into the rectangular groove 12 together
with two groove insertion portions 32, and the U bolt 4 is installed in the second
embodiment. In the same manner, the U bolt 4 is inserted from the front side of
the support member 10, and the screw portion of the U bolt 4 passes through
the bolt insertion holes of the steel net 30 and the cover member 1 and is
engaged using the nut, so that the both sides of the steel net 30 are fixed at the
support member 10.
Figures 8 through 10 show that the rope cover 5 is installed at the portion
in which the wire rope 20 passes through the rope through hole 15 of the
support member 10. The wire rope 20 contacts with the end of the rope through
hole 15 of the support member 10 made of metal. With the above structure, it is
possible to prevent the disconnection of the same.
As shown in Figures 5 and 7, in the steel net 30, the end of the groove
insertion portion 32 is shown by an imaginary line. When the imaginary line is
deleted, the rectangular frame 37 and the groove insertion portion 32 are
formed in an angle shapes, so that with the above method, it is possible to use
the angles which are commercially available in the market. In the case that the
imaginary line portion is included, the horizontal portion is further connected at
the angled portion in a step shape, so that it is needed to separately fabricate
based on the press process, whereby the manufacturing cost increases.
Figure 13 is a view illustrating the support mounting portion 16 for
installing the lower end of the support member 10. In this case, the base plate
19 of the support mounting portion 16 is installed on the ground using the
anchor bolt, and the lower end of the support member 10 is inserted into the
insertion portion doubly formed at the support mounting portion 16, and then the
bolt is laterally installed, so that the installation of the support member 10 is
finished.
Industrial Applicability
As described above, in a falling rock preventing fence assembled with a
steel net, a plurality of support members are provided in a pipe shape having a
rectangular grooves in upper and lower longitudinal directions, with the support
member being installed on the ground at regular intervals, and both ends of the
steel net formed in a rectangular plate shape are inserted into the rectangular
grooves of the neighboring support member and are fixed using a fixture such
as a bolt, etc., and the upper and lower portions of the steel nets stacked in the
upper and lower direction are connected with a connection member such as a
bolt, etc., and the strength of the steel net is enhanced by the rectangular
grooves longitudinally formed in the support member and the end of the steel
net inserted in the rectangular groove, so that the work for installing steel nets
between the support members is easy and simply. Even when a steel net is
damaged by falling rocks or landslide, it is needed to repair only the damaged
portions, so that a maintenance is easy, and a cost for the repair decreases.
As the present invention may be embodied in several forms without
departing from the spirit or essential characteristics thereof, it should also be
understood that the above-described examples are not limited by any of the
details of the foregoing description, unless otherwise specified, but rather
should be construed broadly within its spirit and scope as defined in the
appended claims, and therefore all changes and modifications that fall within
the meets and bounds of the claims, or equivalences of such meets and bounds
are therefore intended to be embraced by the appended claims.
