At present, the size of the domestic demolition market is increasing, but domestic demolition techniques and methods are imported and used by decommissioning methods of developed countries such as Japan and Germany. The demolition work has the biggest disadvantage that it is not environmentally friendly by generating noise, vibration, scattering dust, water pollutants, etc. At present, most of the technologies used in dismantling concrete structures in Korea are wet wire sawing methods.

Although the wet wire saw industry has excellent workability, it has a great disadvantage of generating waste water, scattering dust, and sludge because it uses sprinkling water on the wire saw to cool the wire during operation. It is difficult to apply to ecological preservation areas, hospitals with scattered dust, precision factories, and winter seasons.

In order to solve the problem of the wet wire saw method, various technologies using a cooler or a coolant have been developed, but all of these technologies are forced cooling method using a cooling device, which is not easy to operate the equipment, and the cost of dismantling is excessive. The disadvantage is that it is not easy to do.

Moreover, the cutting operation of the conventional wire saw is often limited to stone or concrete, but the cutting of various materials is required due to the development of the industry. Examples include the dismantling of waste oil tankers, oil field facilities, subsea structures and nuclear power plants.

3 is a plan view showing a wire saw according to an embodiment of the present invention, Figure 4 is a cross-sectional view of the bead. 5 is a three-dimensional view of the beads.

3, 4 and 5, the wire saw 30 according to the present invention is inserted into the wire 31, the wire 31, the first bead 33 and the second having a plurality of identical shapes It consists of the bead 34 and the elastic body 80. Here, the wire 31 is not a deformation in the longitudinal direction, but a flexible steel is preferred.

The wire saw 30 according to the present invention includes a first bead 33, a second bead 34, and an elastic body 80.

The first bead 33 is curved at an angle of 90 °, more specifically, the upper and lower portions of the first bead 33 are curved in the right direction, and the left and right portions are curved in the left direction. The second bead 34 is arranged to face symmetric with the first bead 33. The first bead 33 and the second bead 34 are connected by using the elastic body 80. The second bead connecting one end of the elastic body 80 to the curved groove of the first bead 33 and facing the other end thereof. (34) Connect to the curved groove. That is, by the elastic body 80 it is possible to prevent the rotation of the beads during the cutting operation. The first and

second beads

33 and 34 form a pair, and such units are provided in series.

As a result, the first and

second beads

33 and 34 are respectively installed so that the upper and lower portions are adjacent (N) and the side portions are tangential (W), so that the adjacent portions have a small cutting ability of the structure and the large contact portions have a large cutting ability to turn on the saw. It can create a convincing effect.

Moreover, since the wire saw 30 is rotated at a constant speed during the cutting of the actual structure, it is likely to turn on the saw by alternately contacting the adjacent and distal portions of the

beads

33 and 34 every 90 ° to the cutting plane of the structure. Not only does it create an effect, but its structure is robust, it is not pushed by strong loads, and the thickness of the beads is thin, so cutting is good, heat is generated, and flexibility is excellent.

Here, the

adjacent beads

33 and 34 according to the present invention are shown and described to alternately approach or circumvent alternately at every 90 ° angle, but the present invention is not limited thereto and may be modified to 45 °, 60 °, or the like in advance. Reveal.

The resin coating layer 35 is filled between each of the first and

second beads

33, 34 to serve to hold the

respective beads

33, 34, and the beads 33 ( Only the outer circumferential surface of 34) is exposed.

Here, the resin coating layer 35 is preferably rubber or synthetic resin series having good heat resistance and wear resistance.

In addition, the beads are characterized in that the small alloy containing diamond or CBN (cubic boron nitride) or a metal member to which the diamond particles are electrodeposited or fused.

In the wire saw of the present invention, when cutting the concrete structure, stone or steel, the distance between the outer diameter portion of the bead is close to the rounded contact but the average distance is short, so the member of the rebar is not caught on the edge of the structure or protruding member, or When cutting steel, there is no phenomenon that beads are pushed, so stable cutting can be achieved. In addition, in the case of the wire saw bead close to the assembly structure of the present invention, since the required amount of elastic bodies are present between the beads and the beads, the beads are dispersed from adjacent beads without receiving the cutting load in the longitudinal direction of the beads individually. It is characterized by having a strong resistance to the load in the longitudinal direction generated during cutting.

Here, the conventional wire saw structure has all independent beads (pitch: approximately 25 to 33 mm) and a steel sleeve is placed inside the bead and a diamond bead is placed on the sleeve for firm fixing of the independent bead and the sleeve And the wire is fixed with resin or rubber. In addition, in the case where the bead receives a lot of load in the longitudinal direction, it has a configuration of reinforcing by interposing a spring between the bead and the bead (such as high reinforcement member or steel cutting).

In addition, conventional wire saws usually have an outer diameter of about 11 mm, and the outer diameter of the wire is worn out during use, and in general, the reduction ratio of the diameter is rapidly proportional to the square of the radius compared to the initial amount of wear (the cross-sectional area of the circle). = Circumference X square of the radius). However, due to the nature of the working of the wire saw, a member that has started cutting once cannot be replaced with a new wire saw during cutting, which also means that the width of the cut groove of the cut structure is reduced, so that a new wire saw does not enter the groove. You can't continue working with the wire.

Therefore, the present invention solves this problem at the same time, as shown in Figure 4, by increasing the thickness toward the inner diameter relative to the thickness of the outer diameter portion (that is, the cross-sectional area increases toward the inner side), the use of the bead in the use of the wire saw Faster wear can not complete the cutting of the member, eliminating the resource waste of having to dispose of a usable wire saw even if some beads remain. In other words, the cross-sectional area increases toward the inside, and the cutting speed and cutting capacity are constant from the beginning to the end.

In addition, the short length of each wire saw bead according to the present invention (typically 6.5 mm, 1.5 to 2.5 mm in the present invention) can produce excellent cutting performance, which is important to minimize heat generation during operation and to cool quickly It is characteristic. Therefore, the wire saw according to the present invention can be actively used for the dismantling of the structure that can not be environmentally friendly or wet disassembly.

In addition, the wire saw bead of the present invention is short in length and excellent in flexibility to reduce the fatigue of the operator at work as well as to prevent uneven wear at work and to minimize the cutting noise.

Referring to the operation relationship of the structure dismantling device 100 according to the present invention having such a configuration as follows.

First, the bracket 21 of the guide member 20 corresponding to the cross-sectional shape of the structure 200 is installed along the cut surface of the structure, the wire saw 30 of the wire saw driver 10 and the guide member 20 It is prepared by connecting along the guide roller 23.

Then, the dust cover member 40 is attached to the wire saw 30 and the cut surface of the structure to be cut.

Thereafter, the wire saw driver 10 is operated, and the dust generated at the same time as the cutting surface of the structure 200 is cut by the wire saw 30 is collected in the dust collecting cover member 40 and the cyclone of the dust collector 50 51 is collected and filled in the dust collector 53, suspended fine dust is first collected in the filter 55, forced blow by the blow (57) is collected in the HEPA filter 59 and then outside air Is exhausted.

When the structure 200 is cut by the driving of the wire saw driver 10, the wire saw driver 10 and the dust collector 50 are stopped, the wire saw 30 is removed, and the guide member 20 is removed. After that, clean up the surroundings and dismantle the device.
