Currently, the size of the dismantling market in Korea is increasing, but the dismantling technology and construction methods in Korea are in the situation of importing and using the dismantling methods of developed countries such as Japan and Germany as they are. Demolition work generates noise, vibration, scattered garbage, water pollutants, etc., and has the biggest disadvantage of being not environmentally friendly. Currently, the technology that is mostly used for demolishing concrete structures in Korea is wet. It is a wire saw method.

Such a wet wire saw method is excellent in workability, but in order to cool the heat of the wire during work, it is used while cooling water is being sprinkled on the wire saw, so it generates waste water, scattered garbage, sludge etc. It has major disadvantages, and is difficult to apply in water quality conservation areas, ecological conservation areas, hospitals that are worried about scattered garbage, precision factories, and winter seasons.

In order to solve the problems of the above-mentioned wet wire saw method, various technologies using cold air machines and refrigerants have been developed, but these technologies are all forced cooling systems using a cooling device and the equipment operation is easy. There is a disadvantage that it is not easy to apply to the actual dismantling site because the dismantling cost is too high.

Furthermore, the conventional wire saw cutting operation is often limited to stone or concrete, but various materials are required to be cut due to industrial development. Examples include waste oil shipbuilding, oil field facilities, submarine structures, and dismantling of nuclear power generation facilities.

The outer peripheries are formed so as to be adjacent to or far away from each other at every angle, and the wire saw 30 is driven by the driving machine 10 and guided along the guide roller 23. .

The wire saw driving machine 10 drives the wire saw 30 that cuts the structure 200 by friction. Here, the wire saw driving machine 10 may be similar in configuration to an apparatus used in a conventional wet or air-cooled wire saw method. The wire saw drive device has an electric type and a mechanical type.

The guide member 20 includes a bracket 21 and a plurality of guide rollers 23 for guiding the wire saw 30 drawn from the wire saw driving machine 10 when the structure 200 is cut.

The bracket 21 is installed on the surface of the structure 200 to provide an installation position of the guide roller 23 and is preferably made of a metal square. Also, the shape of the bracket 21 depends on the shape of the structure 200, so that it is a square support type structure as shown in FIG. It may be produced as a modification.

At least one guide roller 23 is provided at a predetermined position of the bracket 21 so as to guide the wire saw 30. Here, all the guide rollers 23 are idle rollers. Moreover, although the present invention employs the guide roller 23 for guiding the wire saw 30, the present invention is not limited to this, and various members that can minimize the frictional force when guiding the wire saw 30 can be selected.

The wire saw 30 according to the present invention is driven by the wire saw driving machine 10 and is provided by being inserted into the metal wire 31 and the wire 31, and a plurality of curved first and second beads 3334 are adjacent to or distant from each other every 90 °. It is installed to be. The first and second beads 3334 are composed of a rubber or synthetic resin series resin coating layer 35 having excellent heat resistance except for the outer peripheral surfaces of the first and second beads 3334, and are guided and installed by the guide roller 23. Is done. The configuration of the wire saw 30 according to the present invention will be described later.

The dust collection cover member 40 adheres along the cut surfaces of the wire saw 30 and the structure 200 in order to prevent dust generated during the cutting process by the wire saw 30 from being released, floated, or dropped. Is preferred.

Here, the dust collection cover member 40 includes a cover 41 and an adhesive layer 45. The cover 41 can be a hard cover or a soft cover, and the hard and soft covers are preferably synthetic resin series. Further, the cover 41 having good stretchability is in close contact with the wire saw 30, and even if the cover 41 is contacted by the operation of the wire saw 30, only a part of the contact is worn. The adhesive layer 45 provided on one side surface of the cover 41 is preferably manufactured from a material having an excellent buffering property with a certain thickness that can be easily detached and attached several times.

The dust collector 50 is provided with a cyclone 51 and a lower part of the cyclone 51 provided to suck and collect dust discharged from a position where the wire saw 30 is pulled out through the dust cover member 40 when the structure 200 is cut by the wire saw 30. The filter 55 and the connecting member provided in the dust collecting cylinder 53 and the connecting member 54 connected to one side surface of the cyclone 51 provided so as to be able to filter the fine dust floating. 54 includes a blow 57 provided in a rear stage portion of 54. Furthermore, the cleaning device 56 for cleaning the internal filter of the cyclone 51 is included on one side surface of the cyclone 51.

The dust collector 50 according to the present invention primarily precipitates fine particles mixed with fine solid matter or liquid floating in a gas by the centrifugal force of the cyclone 51, and collects them in a dust collecting cylinder 53 to be secondary. In addition, the fine dry dust in a floating state is collected through the filter 55 and then exhausted to the outside air through the blow 57. The cyclone 51 serves to primarily filter dust generated during cutting work, and in order to perform the role of the smooth cyclone 51, it must be periodically cleaned. Therefore, the cleaning device 56 for cleaning the internal filter of the cyclone 51 can be installed on one side of the cyclone 51. Preferably, a cleaning device 56 that periodically wipes air and cleans the internal filter is installed.

Here, a HEPA (High Efficiency Particulate Arresting) filter 59 is added to the discharge end portion of the blow 57 so that the same diseases as the pneumoconiosis of workers due to fine dust can be basically prevented even when working indoors. Is provided. The filter 55, the blow 57, and the hepa filter 59 are provided in a separate case 52 that communicates with the cyclone 51.

FIG. 3 is a plan view showing a wire saw according to an embodiment of the present invention, and FIG. 4 is a cross-sectional view of a bead. FIG. 5 is a three-dimensional view of the bead. 3, 4, and 5, the wire saw 30 according to the present invention includes a wire 31, a plurality of first beads 33, second beads 34, and elastic bodies 80 that are inserted into the wire 31 and have the same shape. ing. Here, although the wire 31 is not deformed in the length direction, a flexible steel material is preferable.

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 every 90 °. More specifically, the upper and lower portions of the first bead 33 are curved in the right direction, and the left side and the right side are curved in the left direction. The second bead 34 is arranged in plane symmetry with the first bead 33. The first bead 33 and the second bead 34 are connected by using an elastic body 80, and one end of the elastic body 80 is connected to a groove that is curved in the first bead 33 and the other end is bent into a second bead 34 facing each other. Connect to the groove. That is, the elastic body 80 can prevent the bead from rotating during the cutting operation. The first and second beads 3334 form a set and such unit bodies are continuously installed.

As a result, the first and second beads 3334 are installed so that the upper and lower portions are adjacent to each other and the side portions are disposed in the distance W, so that the adjacent portion has a small cutting ability of the structure, and the distance portion Has a large cutting ability and can create an effect like a saw.

Furthermore, since the wire saw 30 rotates at a constant speed when the structure is actually cut, the effect is such that the cut surface of the structure is alternately brought into contact with the adjacent portion and the distant portion of the bead 3334 every 90 °, and a saw is applied. In addition to creating a solid structure, it is not pushed even by strong loads, the bead thickness is thin, cutting is good and heat generation is low, flexibility is more outstanding and soft cutting is possible as well as mechanical load is reduced.

Here, although the adjacent beads 3334 according to the present invention are illustrated and described so as to be alternately approaching or disengaging every 90 °, the present invention is not limited thereto, and can be modified to 45 °, 60 °, and the like. I will clarify that beforehand.

The resin coating layer 35 is charged between each of the first and second beads 3334 and performs a function of gripping each bead 3334 so that only the outer peripheral surface of the bead 3334 is exposed. Here, the resin coating layer 35 is preferably made of rubber or synthetic resin series having good heat resistance and wear resistance. The bead is a sintered alloy containing diamond or CBN (cubic boron nitride) or a metal member to which diamond particles are deposited by electrodeposition or fusion.

In the wire saw of the present invention, the distance of the outer diameter portion of the bead repeats proximity and distance when cutting a concrete structure, stone or iron material, but the average distance is short and does not affect the corners of the structure or protruding members. Stable cutting can be achieved without the phenomenon that the bead is pushed when cutting a member having many reinforcing bars or steel. In addition, in the case of the wire saw according to the present invention, in the case where the parts are close to each other on the assembly structure of the bead, a necessary amount of elastic body exists between the beads, so that the beads are individually subjected to the cutting load in the length direction of the beads. It is characterized by having a strong resistance to the load in the length direction generated during cutting because it is received in a distributed manner with adjacent beads without being received.

Here, the conventional wire saw has an independent bead (pitch: approximately 25 to 33 mm), and a steel sleeve is installed inside the bead to firmly fix the independent bead. A diamond bead is positioned on the sleeve and the sleeve and the wire are charged with resin or rubber and fixed. Here, in the case of an operation in which the bead receives a large load in the length direction (for example, a high reinforcement member or iron cutting), a spring is interposed between the beads and the beads are reinforced.

Furthermore, most of the conventional wire saws usually have an outer diameter of about 11 mm, and the outer diameter is worn in the process of use, and the diameter reduction ratio is generally the square of the radius compared to the initial wear amount. Cross-sectional area of a circle that progresses rapidly in proportion = Circumference x Square of radius. However, due to the work characteristics of the wire saw, once cut, the member cannot be replaced with a new wire saw in the middle of cutting, and this means that the width of the cut groove of the structure to be cut is reduced. The work is not continued with the new wire unless the wire saw enters the groove.

Therefore, in order to solve such a problem at the same time, the present invention increases the cross-sectional area by increasing the thickness toward the inner diameter side as compared with the thickness of the outer diameter portion as shown in FIG. Increasingly, the wear of the bead when using the wire saw becomes more and more rapid, and it is impossible to complete the cutting of the member, basically eliminating the waste of resources that have to discard the usable wire saw even if some bead remains be able to. That is, the cross-sectional area increases as it goes inward, and the cutting speed and cutting ability are constant from the beginning to the end.

In addition, the wire saw according to the present invention has a short bead length (usually 6.5 mm, 1.5 to 2.5 mm in the present invention), and can provide excellent cutting performance. This makes it possible to minimize heat generation during work, and is an important feature that allows rapid cooling. Therefore, the wire saw according to the present invention can be actively used for environmental protection policies or for dismantling structures that cannot be wet dismantled.

Furthermore, the wire saw of the present invention has a short bead length and excellent flexibility, which not only reduces worker fatigue during work, but also prevents single wear during work and minimizes cutting noise. Can do.

The operational relationship of the structure dismantling apparatus 100 according to the present invention having such a configuration will be described 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, and the wire saw 30 extends along the wire saw driving machine 10 and the guide roller 23 of the guide member 20. Connect and prepare. Thereafter, the dust collecting cover member 40 adheres to the cut surface of the structure to be cut with the wire saw 30.

Thereafter, dust generated simultaneously with the operation of the wire saw driving machine 10 and cutting of the cut surface of the structure 200 by the wire saw 30 gathers in the dust collection cover member 40 and passes through the cyclone 51 of the dust collector 50. The fine dust collected and collected in the dust collecting cylinder 53 is temporarily collected by the filter 55, forcedly blown by the blow 57, collected by the hepa filter 59, and exhausted to the outside air.

At the same time, when the cutting of the structure 200 is finished by driving the wire saw driving machine 10, the wire saw driving machine 10 and the dust collector 50 are stopped, the wire saw 30 is removed, and then the guide member 20 is removed. Arrange the surroundings and dismantle the device.
