Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a structure for dismantling work used when dismantling objects such as various buildings, mechanical facilities, and chemical facilities, and a dustproof method in the dismantling work.
[0002]
[Prior art]
Normally, when a structure such as a building or various mechanical devices is dismantled, the object to be dismantled is shielded with a shield. This shielding is generally performed by assembling a frame surrounding the structure by assembling a frame around the structure and stretching a dustproof sheet on the frame. By doing so, the object to be dismantled is surrounded by the sheet, so that the release of dust generated during the dismantling operation is suppressed. In some cases, a dustproof sheet is stretched twice to improve the dustproof effect.
[0003]
[Problems to be solved by the invention]
By the way, in the conventional dustproof method as described above, the dismantling object is simply covered with the dustproof sheet, and the dust is prevented from scattering to the outside only by the shielding effect of the dustproof sheet. Therefore, the effect of preventing dust scattering is not always sufficient, and it has been impossible to reliably prevent the dust from leaking through the gap of the dustproof sheet.
[0004]
In particular, when the object to be dismantled is an environmental countermeasure facility that contains a lot of harmful substances, such as a waste treatment device, it is common for the dust to contain harmful substances, so if such dust leaks, The problem is that the surrounding environment is contaminated with harmful substances.
[0005]
The present invention has been made in view of the above situation, and a structure for dismantling work and dismantling that can dismantle the object to be dismantled after reliably preventing dust and harmful substances from scattering. The purpose is to provide a dustproof method for construction.
[0006]
[Means for Solving the Problems]
The invention described in claim 1 is a structure for dismantling work for covering the dismantling object when the dismantling process is performed on the dismantling object, and is constructed in a state surrounding the dismantling object. The inner dust-proof building, the outer dust-proof building constructed so as to further surround the inner dust-proof building through a predetermined gap space, and the leakage from the inner dust-proof building caused by the dismantling process in the inner dust-proof building are prevented. Pressure adjusting means for adjusting the pressure inside the inner dust-proof building, and the pressure adjusting means includes a pushing blower for adjusting the pressure in the gap space to a positive pressure, and air inside the inner dust-proof building. And a dust collecting means interposed in the inside / outside communication channel, By making positive pressure in the gap space, the air in the gap space is pushed into the inside dustproof building. It is characterized by being comprised.
[0007]
According to the present invention, the object to be dismantled is in a state of being double surrounded by the inner and outer dustproof buildings, and in particular, the pressure is adjusted by the pressure adjusting means so as to prevent the inside dustproof building from leaking dust. Dust generated in the inner building during the dismantling process of the object to be dismantled due to the synergistic effect of the double measures with the adjustment is effectively prevented from leaking outside from the structure for dismantling work, and dismantling The inconvenience that the vicinity of the construction site is contaminated with the leaked dust is surely prevented.
[0008]
In addition, the presence of the outer dust-proof building does not directly affect the inside dust-proof building due to weather conditions such as wind and rain, and the dismantling work can always be performed in a stable state.
[0009]
Further, according to the present invention, by driving the pushing blower, the gap space between the inner and outer dustproof buildings becomes positive pressure, and the air in the gap space is pushed into the inner dustproof building. The dust generated during the demolition work in the dustproof building is surely prevented from scattering to the outside. Moreover, the air introduced into the inside dustproof building is connected to the inside and outside after it is removed by the dust collecting means. Flow path Since it is discharged to the outside through the dust, scattering of dust from this portion is also reliably prevented.
[0010]
Claim 2 The described invention is claimed. 1 In the described invention, the inner dust-proof building is characterized in that a woven fabric is stretched and formed on a frame constituting the building.
[0011]
According to the present invention, air flows uniformly through the woven fabric cloth covering the frame body and the minute gaps in the connecting portion of the woven fabric with respect to the inner dust-proof building, so that air drift occurs in the inner dust-proof building. There is nothing. Therefore, inconveniences such as local dust dust caused by air drift do not occur, and the inner dustproof building becomes a stable work environment.
[0012]
Claim 3 The described invention is claimed. 1 Demolition work to dismantle the object to be dismantled using the structure for dismantling work described Dust prevention method The outside air is introduced into the gap space by the push-in blower, and the air in the inside dust-proof building, which has become positive pressure, is discharged from the inside / outside communication channel to the outside of the outside dust-proof building via the dust collecting means. It is characterized by doing.
[0013]
According to the invention, the claims 1 The same effects as the invention described in (1) can be obtained.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Prior to the description of the embodiment of the present invention, a first reference example will be described. FIG. First reference example Structure for demolition work related to Things FIG. 2 is a sectional view taken along line AA in FIG. 1. As shown in these figures, a dust-proof temporary building (structure for dismantling work) 10 constructed during dismantling work is used to cover the dismantling target equipment X when the dismantling target equipment X is subjected to dismantling processing. An inner dust-proof building 20 constructed in a state of surrounding the dismantling target equipment X, and an outer dust-proof building 30 constructed so as to further surround the inner dust-proof building 20 via a predetermined gap space 11. And a pressure adjusting means 40 for adjusting the pressure in the inner dust-proof building 20 to a negative pressure so as to prevent the scattered matter generated by the dismantling process in the inner dust-proof building 20 from leaking from the inner dust-proof building 20. It has a configuration.
[0015]
Examples of the facility X to be dismantled include ordinary houses and buildings such as various buildings and various manufacturing facilities constructed in factories. Reference example Considering the fact that the temporary dust-proof building 10 has an extremely excellent dust-proof function, it is extremely suitable to use it for waste incineration equipment, pollution control equipment such as dust collectors, desulfurization equipment, and denitration equipment. .
[0016]
The inner dustproof building 20 and the outer dustproof building 30 are: Reference example In FIG. 3, a frame assembly member 50 as shown in FIGS. 3 and 4 is adopted and constructed. 3 shows the frame assembly member 50. One form FIG. 4 is a perspective view illustrating a state in which the frame assembly member 50 is assembled. As shown in FIG. 3, the frame body assembly member 50 includes a straight unit rod 51 and a spherical joint 55 interposed between adjacent unit rods 51.
[0017]
The unit rod 51 includes a pipe-shaped rod main body 52 and a connecting bolt 53 concentrically screwed to each end face opening of the rod main body 52. A flange 54 for operation such as a nut having a hexagonal shape is provided at a substantially central portion of the connecting bolt 53. The connecting bolt 53 is attached to the rod body 52 by screwing the base end side of the connecting bolt 53 to a female screw threaded on the inner peripheral surface of the rod body 52. There are at least three types of such unit rods 51 having different length dimensions (when the length dimension of the basic unit rod 51 is L, 2 ^1/2 There are three types (xL length and 2xL length).
[0018]
The spherical joint 55 is for connecting adjacent unit rods 51 to each other. A predetermined number of screw holes 56 are provided at appropriate positions on the outer peripheral surface, and the connecting bolt 53 is formed on the inner peripheral surface of the screw hole 56. A female screw corresponding to the male screw is screwed. Therefore, the lens bolt with the tip of the connecting bolt 53 facing the screw hole 56 H The unit rod 51 is attached to the spherical joint 55 by rotating the operation flange 54 around the axis in a predetermined direction using a tool such as.
[0019]
Reference example , The central angle between the core of one screw hole 56 and the core of the other screw hole 56 adjacent to this screw hole 56 is a multiple of 30 ° or 45 °, whereby the unit rod Various three-dimensional frame bodies 13 can be constructed by combining 51 and the spherical joint 55.
[0020]
However, the central angle between the hole core of one screw hole 56 and the hole core of another screw hole 56 adjacent to the screw hole 56 should be an arbitrary angle as long as the screw holes 56 do not interfere with each other. It is possible to cope with any three-dimensional shape of the dustproof temporary building 10 to be constructed by appropriately selecting the above angle.
[0021]
And since the object (dismantling object equipment X) which the temporary building 10 for dust protection covers changes in a shape and a scale according to a required function or site conditions, the temporary building 10 for dust protection can be easily and easily adapted to these. In order to construct quickly, it is an important requirement that the installation position of the screw hole 56 can be arbitrarily set. From this viewpoint, the position of the screw hole 56 can be arbitrarily set. Reference example The spherical joint 55 is suitable.
[0022]
By the way, generally, considering the cost of a building (dismantling target equipment X), it is preferable to make the shape of the building as simple as possible. This is because the cost can be reduced by simplifying the building. From this point of view, it is possible to make the parts common to both the unit rod 51 and the spherical joint 55 after setting the center angle between the cores of the adjacent screw holes 56 to a predetermined angle. is important. By doing so, the particularity of the parts is eliminated, a building having a simple shape can be easily constructed, and reuse of the frame assembly member 50 in other plans is facilitated. Which type of frame assembly member 50 is to be adopted is determined based on each specific case, taking various conditions into consideration.
[0023]
And Reference example , A so-called truss structure that is structurally strong, in which these unit rods 51 are assembled so as to form many triangles via spherical joints 55, is adopted in advance on the site around the dismantling target equipment X. By assembling the structure on the concrete foundation 12 having a rectangular shape in plan view, a double-structured box-shaped frame 13 as shown in FIGS. 4 and 1 and 2 is obtained. ing.
[0024]
The inner dust-proof building 20 has a wire 13 or the like that is an inner film 21 made of a sheet on the inner side of an inner frame made up of a large number of unit rods 51 and spherical joints 55 of the frame 13 obtained as described above. It is formed by stretching using a substantially locking member.
[0025]
The interior membrane 21 is Reference example In Japan, a thin woven product obtained by weaving synthetic fibers made of synthetic resin such as polyethylene or polypropylene, or a composite product obtained by coating a surface of vinylon or polyester with a tough synthetic resin material is employed. By adopting such a woven product, the interior membrane 21 can be air circulated satisfactorily and at a low cost. In particular, it is important that the interior film 21 is low cost. This is because the interior film 21 has absorbed a lot of harmful substances at the time when the dismantling work is completed, so that it is packed in a flexible container bag and reliably decomposed in a melting furnace to prevent the harmful substances from being released into the environment. This is because it is a so-called disposable product that is subjected to the treatment, and therefore, it is a factor that increases the cost of the dismantling process if it is expensive.
[0026]
The reason is that when the dismantling work in the dust-proof temporary building 10 is completed, a large amount of dust containing harmful substances is attached to the surface of the interior film 21, so that the contaminated interior film 21 is removed. It cannot be used and is usually disposed of as a disposal. Therefore, since a new interior film 21 is used every time the dismantling work is performed, it is desired that the interior film 21 which is such a consumable is low-cost in order to reduce the cost of the dismantling work. In addition, since olefinic hydrocarbons such as polyethylene and polypropylene do not contain chlorine, no harmful substances such as dioxins are generated even if they are subjected to incineration. Suitable as
[0027]
The reason why the interior film 21 can be made of an inexpensive lightweight product is that the dustproof temporary building 10 has a double structure of the inner dustproof building 20 and the outer dustproof building 30. That is, since the inner dust-proof building 20 is covered by the outer dust-proof building 30, the inner dust-proof building 20 is not directly affected by weather conditions such as wind and rain or solar radiation, and thus can be a thin and light product.
[0028]
Then, in a state where the interior film 21 is stretched on the frame body 13, a seal construction is performed in which a sealing agent is filled in the joint portion between the adjacent interior films 21, thereby short-circuiting the inner dustproof building 20. Without doing so, only the air filtered through the interior membrane 21 is supplied. In addition, when air is difficult to permeate the interior membrane 21, a portion where sealing is not applied is provided at the joint portion between the interior membranes 21. Ru For example, air may be introduced from this portion. In addition, air may be introduced into the interior film 21 from slight gaps at various locations in the interior film 21 without providing a portion that is not actively sealed.
[0029]
The outer dustproof building 30 includes an outer wall film 31 stretched on the outer peripheral surface side of an outer frame composed of many unit rods 51 and a spherical joint 55 outside the frame body 13, and an upper part of the ceiling portion of the frame body 13. And a roof member 32 to be covered.
[0030]
The outer wall film 31 is Reference example Is a thick synthetic resin sheet. Such a synthetic resin sheet is used because the outer wall film 31 is directly exposed to the outside air and directly affected by weather conditions such as wind and rain and direct sunlight, and after the dismantling work is completed, the inner film Therefore, a thick synthetic resin sheet having excellent weather resistance and high strength is used so as to withstand these.
[0031]
Further, the joint portions of the outer wall film 31 are joined to each other by heat welding using a bonding film, direct hot air welding between the outer wall films 31, or adhesion via an adhesive. I'm trying not to be done. Further, a plurality of gallans 33 for taking in outside air are provided at appropriate positions on the outer wall film 31, and outside air can be taken into the inside dust-proof building 20 through the gap space 11 from the gallan 33.
[0032]
The roof member 32 is configured using a corrugated metal plate. The roof member 32 is constructed on the top of the frame 13 as a gable roof so that the central portion is a diversion basin and a downward slope is formed toward the edge in the width direction. To be done. In addition, the roof member 32 is not limited to being made of metal, and a lightweight roof material such as a synthetic resin flat plate, corrugated plate, or tent film material can also be suitably used.
[0033]
Furthermore, a loading / unloading building 34 for unloading the dismantled material generated in the dismantling process of the dismantling target equipment X and loading necessary equipment is constructed at a suitable place on the outer wall surface of the outer dustproof building 30.
[0034]
The loading / unloading building 34 includes a building main body 35 having a gable roof, a first door 36 provided in the building main body 35 for opening and closing an opening communicating with the inside of the inside dustproof building 20, and the building main body 35. And a second door 37 interposed between the outside and the outside. When carrying out the dismantling, the first door 36 is opened and the dismantling is once moved into the building main body 35, and then the first door 36 is closed and then the second door 37 is opened to carry out the dismantling. Thus, dust in the inner dust-proof building 20 is prevented from leaking directly to the outside. When the equipment is carried into the inner dust-proof building 20, the first door 36 is opened and closed after the second door 37 is opened and closed contrary to the above.
[0035]
The pressure adjusting means 40 includes a suction blower 41 installed on a site near the outer dustproof building 30, a suction duct 42 laid between the suction blower 41 and the inner dustproof building 20, and the suction duct 42. And a dust collection filter (dust collection means) 43 interposed therebetween. Then, when the suction blower 41 is driven, the inside of the inner dustproof building 20 becomes negative pressure as air is extracted through the suction duct 42, and thereby the outside air flows into the gallan 33 and the outer dustproof building 30 of the outer dustproof building 30. It is introduced into the inner dust-proof building 20 through the space 11 between the inner dust-proof building 20 and the interior film 21.
[0036]
In addition, dust generated by the dismantling process is removed by a dust collection filter 43 provided in the suction duct 42, and cleaned air is discharged from the suction blower 41 to the outside.
[0037]
First reference example As described in detail above, the dust-proof temporary building 10 is a structure for demolition work that is used to cover the dismantling target facility X when the dismantling target facility X is subjected to dismantling processing. The inner dust-proof building 20 constructed in a state of surrounding X, the outer dust-proof building 30 constructed so as to further surround the inner dust-proof building 20 via a predetermined gap space, and the dismantling process in the inner dust-proof building 20 Since the generated dust is provided with pressure adjusting means 40 for adjusting the pressure in the inner dust-proof building 20 so that leakage from the inner dust-proof building 20 is prevented, the dismantling target equipment X is provided on the inner side. The pressure adjusting means 40 adjusts the pressure so that the inside of the inner dust-proof building 20 is prevented from leaking dust. The dust generated in the inner building during the dismantling process of the dismantling target equipment X due to the synergistic effect of the dual measures with the existing measures is effectively prevented from leaking out of the structure for dismantling work. It is possible to reliably prevent the inconvenience that the vicinity of the construction site is contaminated with the leaked dust.
[0038]
Moreover, the inside of the inner dust-proof building 20 is not directly affected by weather conditions such as wind and rain due to the presence of the outer dust-proof building 30, and the dismantling operation can be executed in a stable state at all times.
[0039]
And especially First reference example The pressure adjusting means 40 is provided with a suction blower 41 for adjusting the pressure inside the dustproof building 20 to a negative pressure, a suction duct 42 connecting the suction blower 41 and the inside dustproof building 20, and the suction duct 42. Therefore, when the suction blower 41 is driven, the inside dust-proof building 20 has a negative pressure and the outside air is drawn. 2 As shown by the arrows in FIG. 6, since the air is sucked into the inner dust-proof building 20, it is possible to reliably prevent the dust generated during the dismantling work in the inner dust-proof building 20 from being scattered to the outside.
[0040]
In addition, the air in the inner dustproof building 20 sucked by the driving of the suction blower 41 is discharged to the outside after being cleaned by the dust collection filter 43 provided in the suction duct 42 on the upstream side of the suction blower 41. Therefore, it is possible to reliably prevent the inconvenience that dust generated in the inner dust-proof building 20 is scattered with the suction air sucked by the suction blower 41 to the outside.
[0041]
Next, an embodiment of a structure for dismantling work according to the present invention will be described. FIG. 5 shows a structure for demolition work according to the present invention. One embodiment FIG. In the dustproof temporary building (structure for dismantling work) 10a of this embodiment, the pressure adjusting means 40a is First reference example Instead of the suction blower 41, a pushing blower 41a is employed. The pushing duct 42a corresponding to the suction duct 42 is provided between the pushing blower 41a and the gap space 11 formed between the inner dustproof building 20 and the outer dustproof building 30, and the driving of the pushing blower 41a is performed. The outside air taken in is passed through the push-in duct 42a and is introduced into the gap space 11 via the dust collection filter 43.
[0042]
Also, This embodiment In, the tip provided on the outer wall film 31 of the outer dustproof building 30 First reference example A plurality of inner and outer communication pipes 44 penetrating the inner dust-proof building 20 and the outer dust-proof building 30 and a pressure adjusting valve 46 for adjusting the pressure in the gap space 11 are provided instead of the galan 33. A dust collection filter 45 is provided on the inlet side of the inside / outside communication pipe 44 (inside the inside dustproof building 20), and the air in the inside dustproof building 20 is communicated inside and outside in a state where the dust is removed by the dust collection filter 45 and cleaned. It is discharged to the outside through the pipe 44.
[0043]
Further, the pressure control valve 46 is provided in a pressure control pipe 47 projecting outside from the outer wall film 31, and the outflow of air in the gap space 11 through the pressure control pipe 47 by adjusting the opening degree and the pushing blower 41a. The pressure in the gap space 11 is adjusted by the supply and demand balance of air with the introduction of air into the gap space 11 by driving.
[0044]
further, This embodiment The outer wall film 31 is First reference example Instead of the synthetic resin sheet, a thick woven fabric having air permeability is employed. By doing so, the air in the gap space 11 that has been made positive pressure is discharged to the outside through the cloth, and even if the outside air is dirty, the contaminated air is not introduced into the gap space 11. I am doing so.
[0045]
And other configurations of the dust-proof temporary building 10a (the frame 13 of the truss structure by the frame assembly member 50 for configuring the inner dust-proof building 20 and the outer dust-proof building 30 and the carry-out provided at appropriate positions of the outer dust-proof building 30 Admission building 34) First reference example It is the same.
[0046]
This embodiment According to the dust-proof temporary building 10a, the pressure adjusting means 40a includes a pusher blower 41a that adjusts the inside of the gap space 11 to a positive pressure, and an internal / external communication pipe that discharges the air in the inner dust-proof building 20 to the outside of the outer dust-proof building. 44 and a dust collecting filter 45 interposed in the inner / outer communication pipe 44, so that by driving the pushing blower 41a, the inside of the gap space 11 between the inner and outer dustproof buildings becomes positive pressure, The air in the gap space 11 is pushed into the inner dust-proof building 20, so that it is possible to reliably prevent the dust generated during the dismantling work in the inner dust-proof building 20 from being scattered outside. Moreover, since the air introduced into the inner dust-proof building 20 is removed by the dust collecting filter 45 and then discharged to the outside through the inner / outer connecting pipe 44, it is also possible to reliably prevent dust from being scattered from this portion. Can do.
[0047]
FIG. According to the second reference example It is explanatory drawing for demonstrating the processing method of a demolition thing. As shown in this figure, the processing method for the dismantled product X1 includes a separation step P1 for separating the generated dismantled product X1, a horizontal holding step P2 for holding the separated dismantled product X1, and a horizontally dismantled product. The process consists of a temporary storage process P3 for temporarily storing X1 and an unloading process P4 for unloading the temporarily dismantled product X1.
[0048]
The separation process P1 is a process of separating the dismantled object X1 generated in the dismantling work in the dustproof temporary building 10, 10a in the dustproof temporary building 10, 10a. Here, the dismantled object X1 Type (for example, classification into pollutants contaminated with hazardous substances and non-contaminated non-contaminated substances as the first classification, metal pieces, concrete pieces, plastic pieces as the second classification for both pollutants and non-contaminated substances Sorted into combustibles, etc.). The separated dismantled product X1 is stored in a flexible container bag (flexible container bag) 1 color-coded for each type according to the classification type.
[0049]
The horizontal holding process P2 is a process of holding the dismantling target equipment X stored in the flexible container bag 1 in the dust-proof temporary buildings 10 and 10a toward the temporary storage building 3 in the field, and storing the dismantling object X1. The flexible container bag 1 is horizontally held up to the temporary storage building 3 by using the forklift truck 2.
[0050]
In the temporary storage process P3, the flexible container bag 1 in which the dismantled articles X1 horizontally held in the temporary storage building 3 from the dust-proof temporary buildings 10 and 10a by the forklift truck 2 is stored for each type of the dismantled object X1 inside. It is the process of accumulating in and storing temporarily. And since the color of the flexible container bag 1 is different for each type of the dismantled product X1, it is possible to easily and reliably accumulate each type of the dismantled product X1 by this color coding.
[0051]
In the carry-out process P4, the flexible container bag 1 accumulated in the temporary storage building 3 in the previous temporary storage process P3 is mounted on the transport vehicle 4 such as a truck using the forklift truck 2 for each type of the dismantled object X1. Then, it is carried to the final disposal site 5 and the final waste treatment for the dismantled material X1 is executed.
[0052]
The final disposal site 5 into which the dismantled material X1 is carried is determined in advance for each type of the dismantled material X1. For example, when the dismantled material X1 is contaminated with high concentrations of harmful substances, the management type A final disposal site is selected, and high-concentration contaminants are sent to a managed final disposal site after a so-called concrete solidification process that seals and solidifies in ready-mixed concrete. If the demolition X1 is of a low level of contamination and is a metal or combustible material that can be pyrolyzed, a shaft furnace type melting furnace is selected as the final disposal site 5, and the demolition is performed. The product X1 is subjected to a thermal decomposition treatment at a high temperature of 1200 ° C. or higher. Moreover, when the demolished material X1 is not suitable for thermal decomposition processing of concrete pieces or the like that are not contaminated with harmful substances, a landfill is selected as the final disposal site 5 and subjected to landfill processing. When the dismantled material X1 is a combustible material such as a piece of cloth or wood that is not contaminated, a normal incineration site is selected as the final disposal site 5 and is subjected to an incineration process.
[0053]
According to the second reference example As described in detail above, the processing method of the dismantled product X1 is the separation step P1 for separating the dismantled product X1 by type in the inner dustproof building 20, and the dismantled product X1 separated in this separation step P1 to the inner dustproof building 20 A side-holding process P2 that is laterally held from the inside to the external temporary storage building 3, and a temporary storage process P3 that accumulates and temporarily stores the dismantled articles X1 carried out in the side-holding process P2 for each type of the dismantled objects X1. And the dismantling material X1 accumulated and stored for each type in the temporary storage step P3, and the unloading step P4 for unloading the dismantling material X1 to the final disposal site 5 outside the system. The dismantled product X1 disassembled inside is separated by type in the separation process P1, and the dismantled product X1 separated in this separation process P1 is horizontally held from the inner dust-proof building 20 to the external temporary storage building 3 in the horizontal holding process P2. Is this holding The dismantled product X1 carried out in the process P2 is accumulated for each type of the dismantled product X1 in the temporary storage process P3, and the dismantled product X1 collected and stored for each type in the temporary storage process P3 is used for each type in the unloading process P4. It is carried out to the final final disposal site 5.
[0054]
In this way, the dismantled material X1 separated for each type at the generation site is once arranged in the temporary storage building 3 as a relay point and accumulated for each type, and then combined for each type to suit each type. Since it is carried out to the optimal final disposal site 5, the temporary storage building 3 is compared with the case where the demolition X1 generated at the demolition site in the inner dustproof building 20 is immediately carried out toward the final disposal site 5. As a result, the work efficiency is improved as much as each type is collected, and it is possible to contribute to the reduction of the processing cost of the dismantled product X1 after dismantling.
[0055]
The present invention is not limited to the above embodiment, and includes the following contents.
[0056]
(1) Above First reference example and In the embodiment, the inner dust-proof building 20 and the outer dust-proof building 30 are formed by using the frame body 13 of the truss structure formed by combining the frame body assembly member 50 as a constituent element. The inner dust-proof building 20 and the outer dust-proof building 30 are not limited to be constructed by the frame body 13, and the inner dust-proof building and the outer dust-proof building are configured by a normal box-shaped structure composed of columns and beams.

(2) Above First reference example and In the embodiment, the dust collecting filter 43 is employed as the dust collecting means, but the present invention is not limited to the dust collecting means being the dust collecting filter 43, and water is sprayed on the suction air. Alternatively, a so-called wet dust collector such as submerging water in the suction air may be employed.
[0058]
(3) Above First reference example In this case, a filter may be provided in the gallan 33 provided on the outer wall film 31. By doing so, the air introduced into the inner dust-proof building 20 through the gap space 11 can be made clean.
[0059]
(4) Above First reference example , A synthetic resin sheet that does not allow air to flow is used as the outer wall film 31, but a woven fabric may be used as the outer wall film 31 instead. By adopting the woven cloth, it is possible to introduce the outside air into the gap space 11 through the cloth of the outer wall film 31 without particularly providing the galvan 33 on the outer wall film 31.
[0060]
(5) Above The fruit In the embodiment, a woven fabric capable of air flow is employed as the outer wall film 31, but the outer wall film 31 may be formed of a synthetic resin sheet that blocks air flow. In this way, air is prevented from being discharged through the outer wall film 31, so that the amount of air introduced by the pushing blower 41a can be reduced by that amount, and the energy cost for driving the pushing blower 41a accordingly. Contributes to the reduction of
[0061]
(6) Above First reference example and In the embodiment, an entrance / exit facility for an operator of dismantling processing as shown in FIG. 7 may be constructed adjacent to the dust-proof temporary buildings 10 and 10a. This entrance / exit facility 60 is formed by a substantially square building in plan view constructed so as to be in contact with the outer wall of the outer dust-proof building 30, and is L-shaped in plan view formed at a position separated from the outer dust-proof building 30. The dressing room 61 and a dressing room 62 formed so that two sides are surrounded by the dressing room 61 have a basic configuration.

And a driving pin 59c projecting from the head. The bolt body 59a is set to have a diameter slightly smaller than the inner diameter of the wapper 57b, so that the bolt body 59a can be fitted into the sleeve 57a from the inside.
[0075]
The driving pin 59c is fitted into the elongated hole 57c of the wapper 57b in a sliding contact state so as to be able to move forward and backward in the axial direction, and in the state where the bolt main body 59a is fitted into the wapper 57b. The bolt 59 is fixed to the bolt 59 by being screwed into a screw hole screwed in advance on the peripheral surface of 57b through a long hole 57c.

(9) FIG. In the third reference example It is a longitudinal cross-sectional view which shows the structure for such demolition work. As shown in this figure, Of this reference example The dustproof erection building (structure for dismantling work) 10b is basically First reference example However, the inside of the clearance space 11 is adjusted to a negative pressure, and the inside of the inside dust-proof building 20 is adjusted to a negative pressure lower than that in the clearance space 11. The point configured in First reference example It is different from the one. And in order to make the inside dust-proof building 20 the negative pressure lower than the inside of the gap space 11, Reference example In First reference example The gallan 33 (FIGS. 1 and 2) used in the above is not provided.
[0078]
like this Of this reference example According to the dustproof erection building 10 b, when the suction blower 41 is driven, the interior film 21 is depressurized to a negative pressure, and the outside air tends to be sucked into the interior film 21. However, since the outer wall film 31 is not provided with the galley 33, the outside air passes through a slight gap at the joint portion between the adjacent outer wall films 31 and is once formed between the outer wall film 31 and the interior film 21. 11 is introduced into the inner dust-proof building 20 through a slight gap (that is, a portion not subjected to the sealing process, the same applies hereinafter) at the joint portion between the adjacent inner membranes 21 and sucked into the inner membrane 21. Then, it is led out through the suction duct 42, the dust collection filter 43 and the suction blower 41.
[0079]
The outside air sucked by the drive of the suction blower 41 first causes a pressure loss when passing through the gap between the adjacent outer wall films 31, so that the gap space 11 has a negative pressure lower than the atmospheric pressure. Further, since the air in the gap space 11 also has a pressure loss when passing through the interior membrane 21 or passing through the gap, the inner dustproof building 20 is eventually at a lower pressure than the gap space 11. And since the inside of the inner dust-proof building 20 is in a state protected by double negative pressure, the dust generated in the inner dust-proof building 20 during the dismantling operation of the dismantling target equipment X is more surely scattered. To be prevented.
[0080]
In addition, about the clearance dimension of the junction part between the adjacent outer wall films | membranes 31 provided in order to introduce external air into the inside dustproof building 20, and the clearance gap dimension between the adjacent interior film | membranes 21, the pressure loss which arises by the said clearance gap It is necessary to set it appropriately by taking into account the value of and the situation of the four circles.
[0081]
Also, Reference example , The suction duct 42 ′ is buried in the soil so that the central portion passes under the concrete foundation 12. In this way, the previous First reference example Thus, there is no need to open a hole for passing the suction duct 42 through the interior film 21 and the outer wall film 31 or to perform a sealing process between the periphery of the hole and the outer peripheral surface of the suction duct 42. In addition to being able to contribute to the efficiency of the construction work of the dust-proof erection building, and since these films are not damaged, particularly in the case of the outer wall film 31, it is convenient to reuse the outer wall film 31. .
(10) FIG. According to the fourth reference example Structure for demolition work Things It is a longitudinal cross-sectional view shown. As shown in this figure, According to the fourth reference example The dust-proof erection building (structure for demolition work) 10c is basically the point that the gap space 11 is made negative. According to the third reference example Although it is in line with the dust-proof erection building 10b, not only does it rely on pressure loss but also positively creates negative pressure in the gap space 11. Third reference example It is different from the one.
[0082]
That is, Of the fourth reference example In the dustproof erection building 10c, in addition to the suction blower 41 that sucks air in the inner dustproof building 20 to make the inner dustproof building 20 negative pressure, the gap space 11 is positively adjusted to negative pressure. For this purpose, another dedicated suction blower (second suction blower 48) is employed.
[0083]
Of the fourth reference example According to the dust-proof erection building 10c, the second suction blower 48 for positively applying a negative pressure in the gap space 11 is adopted, so that the second suction blower 48 is appropriate in relation to the suction blower 41. It is possible to easily set the pressure in the gap space 11 to an appropriate value without relying only on the pressure loss of the air passing through the gap between the adjacent outer wall films 31 by controlling the operation to This is convenient when the pressure in the space 11 is set to a negative pressure between the external pressure and the pressure in the interior membrane 21.
[0084]
(11) Above Reference examples and actual In the embodiment, a predetermined dust collector may be separately introduced into the inner dust-proof building 20, and the air in the inner dust-proof building 20 may be cleaned with the dust collector. By doing so, the inside of the inside dustproof building 20 becomes a cleaner working environment by the cooperation of the dust collector and the dust collecting filter 43 of the pressure adjusting means 40, 40a.
[0085]
【The invention's effect】
According to the structure for demolition work according to claim 1, the demolition object is in a state of being double surrounded by the inner and outer dust-proof buildings, and in particular, the inner dust-proof building interior is free from dust leakage. By adjusting the pressure by the pressure adjusting means so as to prevent, dust generated in the inner building during the dismantling process of the dismantling object is effectively suppressed from leaking out from the structure for dismantling work, It is possible to reliably prevent inconvenience that the vicinity of the demolition work site is contaminated with the leaked dust. In addition, the presence of the outer dust-proof building does not directly affect the inside dust-proof building due to weather conditions such as wind and rain, and the dismantling work can always be performed in a stable state. Furthermore, the pressure adjusting means is interposed between the pushing blower for adjusting the pressure in the gap space to a positive pressure, the internal / external communication channel for discharging the air inside the dustproof building to the outside of the dustproof building, and the internal / external communication channel. Therefore, by driving the push-in blower, the gap space between the inner and outer dust-proof buildings becomes positive pressure, and the air in this gap space is pushed into the inner dust-proof building, It is possible to reliably prevent the dust generated by the dismantling work in the inside dustproof building from being scattered to the outside. Moreover, since the air introduced into the building is removed by the dust collecting means and then discharged to the outside through the internal / external communication pipe, it is possible to reliably prevent dust from being scattered from this portion.
[0086]
Claim 2 According to the structure for demolition work described above, the inner building is formed by stretching the woven fabric on the frame constituting the building, so that the cloth texture of the woven fabric covering the inner frame of the dust-proof building Through the air, air can flow uniformly, and the drift of air in the inside dust-proof building can be prevented. Therefore, inconveniences such as local dust dust due to air drift do not occur, and the inside dustproof building can be a stable work environment.
[0087]
Claim 3 According to the demolition work method described, the claim 1 A demolition work method using the structure for demolition work described in the above, wherein outside air is introduced into the gap space by a push-in blower, and the air inside the dustproof building inside that has become positive pressure is passed through the dust collection means. Because it is positively discharged from the communication channel to the outside of the dustproof building outside, the claim 1 The same effect as the invention described in (1) can be obtained.
