Description

The present invention relates to a shatterproof curing system and a structure dismantling method using the same, and in particular, a vertical support structure stacked on the outside of a predetermined portion of an opposite outer wall of a structure to be dismantled and a vertical support structure facing each other. A shatterproof curing system that is relatively lightweight and easy to replace by supporting the shatterproof curing body with a shatterproof curing body support that consists of an upper support that spans between the uppermost parts of the body, and a shatterproof curing system that uses it. Regarding the structure dismantling method.

There is a growing need to dismantle high-rise buildings that have been built so far for rebuilding due to factors such as aging, changes in the usage environment, and redevelopment, although they have a useful life.
When dismantling a target structure such as a high-rise building, in order to ensure the safety of the surroundings during the dismantling work, the surroundings and the upper part of the target structure are covered with a shatterproof living body such as a sheet or a net, and it occurs at the time of dismantling. It is done to prevent the scattering of debris. When dismantling a target structure such as a high-rise building, heavy equipment for dismantling is usually lifted and installed on the top floor, and the dismantling proceeds in order from the upper floor. Along with this, the scaffolding built around the outer wall of the dismantled upper floor will be dismantled and the anti-scattering organism will be removed, but the anti-scaffolding organism that covers the upper part of the target structure cannot be removed. Therefore, it is necessary to sequentially lower the target structure to the lower layer according to the dismantling status of the target structure.

If the anti-scaffolding organism that covers the upper part of the target structure is attached so as to cover the scaffolding installed around the target structure, the height of the anti-scaffolding organism will decrease as the scaffolding is dismantled. Management and operation becomes easy. However, the height of the scaffold that is installed independently and higher than the target structure is limited to two steps, and in the case of a general scaffold with a height of 1.8 m, the height is 3.6 m even with two steps, which is the highest. The height is not enough to secure the work space for heavy machinery installed on the floor. For this reason, when dismantling a large target structure, a structure such as a truss that supports the anti-scaffolding organism is installed separately from the scaffolding, and a construction method is performed to cover the anti-scattering organism from above. Therefore, there is a problem that it is not easy to sequentially lower the shatterproof nutrient body to the lower floors according to the dismantling status of the target structure because it involves the work of lowering the heavy truss.

Patent Document 1 describes a work scaffold that is projected higher than the outer wall of the building on the outside of the outer wall of the building to be dismantled, and a curing sheet support pillar that is fixed to the work scaffold so as to be projected higher than the work scaffold. When the work scaffolding is gradually removed from above in response to the progress of dismantling from the upper floors to the lower floors, equipped with a shatterproof curing sheet moored to the curing sheet support pillar so that the tension can be adjusted. Disclosed is an upward shatterproof curing system that moves the curing sheet support pillar downward along the work scaffolding.

According to the invention described in Patent Document 1, the anti-scaffolding body can be installed at a position higher than the scaffolding by the curing sheet support pillar protruding higher than the scaffolding, but on the other hand, the scattering prevention curing body can be installed on the upper part of the target structure. Since there is nothing to support the preventive curing body, the shatterproof curing body inevitably bends in the central part of the target structure, and it is easily affected by snowfall and strong winds. Issues such as the tendency for unexpected loads to be applied to the scaffolding remain.

Patent Document 2 includes a guide rail and an elevating platform, which are installed on both sides of a high-rise building and consist of a construction elevator extending from the ground to the rooftop and a truss steel material of a predetermined length, which are connected and connected to form a high-rise building. It is equipped with multiple roof trusses that are hung on the roof and attached to the elevator platform of the construction elevator, and shatterproof nets and seats that are attached to the roof truss. A shatterproof curing system is disclosed in which the roof crane is lowered by a construction elevator as the floor is dismantled when the high-rise building is dismantled toward the ground.

According to Patent Document 2, the shatterproof net and the seat attached to the roof truss can be easily lowered together with the roof truss by the construction elevator, so that the dismantling work can be carried out very efficiently. However, it is necessary to install a plurality of construction elevators that support a plurality of roof trusses that can cover at least the entire target structure, which causes a problem that the installation is troublesome and the system cost is high.
Therefore, it has strength separate from the scaffolding, can be installed relatively easily, and reliably supports the anti-scattering organism, and it is also relatively easy to lower the anti-scattering organism as the dismantling work progresses. It is desired to provide a curing system and a structure dismantling method using the curing system.

The present invention has been made in view of the problems in the above-mentioned conventional shatterproof curing system and the structure dismantling method using the same, and an object of the present invention is to determine the facing outer wall of the structure to be dismantled. By supporting the anti-scattering organism with an anti-scattering bio-support consisting of a vertical support structure stacked on the outside of the portion and an upper support spanning between the uppermost portions of the opposing vertical support structures. It is an object of the present invention to provide a shatterproof curing system that is relatively lightweight and easy to refill, and a structure dismantling method using the same.

In the anti-scattering curing system according to the present invention, which has been made to achieve the above object, a heavy machine for dismantling is lifted on the top floor of the structure to be dismantled to secure a working space by the heavy machine and dismantle the target structure. This is a shatterproof curing system applied to the dismantling of a structure to be dismantled, in which a plurality of columnar members and a plurality of columnar members are vertically erected outside a predetermined portion of an opposite outer wall of the target structure to be demolished. At least a pair of vertical support structures formed by vertically stacking a plurality of basic structures having a plurality of horizontal members connected in the horizontal direction, and the object to be bridged over the uppermost portion of the at least pair of vertical support structures. A shatterproof nutrient support provided with an upper support that covers the upper part of the structure and supports the shatterproof nutrient, and a portion of the shatterproof nutrient support from at least the uppermost portion to a predetermined height is temporarily suspended. It has a suspending means for lowering, the anti-scattering body , and a scaffold configured to surround the outer wall of the target structure and the outer periphery of the vertical support structure, and the anti-scattering body support is the scaffold. It is characterized in that it is independently provided higher than the scaffold .

When there are a plurality of the anti-scattering biosupports, it is preferable that at least a pair of the anti-scattering biosupports are installed at a distance from each other by a predetermined distance.
The vertical support structure is formed by stacking from the ground to a height higher than the top floor of the target structure so as to secure a work space required for dismantling the top floor of the target structure, or is formed in the middle of the target structure. It is stacked from above the intermediate support that overhangs the outer wall of the intermediate floor of the target structure through the opening of the outer wall of the floor to a height that can secure the work space required for dismantling the top floor of the target structure. Is preferably formed.

After the uppermost floor of the target structure is dismantled, the suspending means either removes the basic structure at an intermediate height of the anti-scattering biosupport or replaces the intermediate support with a lower floor. It is preferable to temporarily suspend a portion of the shatterproof biosupport from at least the uppermost portion to a predetermined height.

In the structure dismantling method using the shatterproof curing system according to the present invention, which was made to achieve the above object, a heavy machine for dismantling is lifted on the top floor of the structure to be dismantled to secure a work space by the heavy machine. This is a structure dismantling method for advancing the dismantling of the target structure, in which a plurality of columnar members and a plurality of columnar members are vertically erected outside a predetermined portion of an opposite outer wall of the target structure to be dismantled. After forming at least a pair of vertical support structures by vertically stacking a plurality of basic structures composed of a plurality of horizontal members connected in the horizontal direction, the target structure is placed on the uppermost portion of the at least pair of vertical support structures. A stage of forming an anti-scattering nutrient support by spanning an upper support that supports the anti-scattering organism that covers the upper part, and a stage of installing a scaffold so as to surround the outer periphery of the target structure and the vertical support structure. The step of covering the top floor of the target structure with the shatterproof nutrient from above the shatterproof nutrient support, the stage of dismantling the top floor of the target structure, and the shatterproof nutrient support. The anti-scattering biosupport is provided separately from the scaffold and higher than the scaffold, and the vertical support structure is either stacked from the ground or the target structure. When stacked on an intermediate support overhanging the outer wall of the intermediate floor of the target structure through the opening of the outer wall of the intermediate floor of the object, and when stacked from the ground, the scattering above the intermediate floor. The anti-scattering bio-support is temporarily suspended after removing several steps of the basic structure below the middle part while the preventive bio-support is temporarily suspended by the suspending means. When the intermediate support is stacked on the intermediate support, the intermediate support is temporarily suspended by the suspending means, and the intermediate support is placed on the lower floor. It is characterized in that the refilling is performed by lowering the shatterproof biosupport that is temporarily suspended after the refilling.

According to the shatterproof curing system according to the present invention and the structure dismantling method using the same, it is necessary to install the shatterproof curing body so as to secure the work space required for dismantling the top floor of the target structure. Since the anti-scattering bio-support is installed only in the necessary parts, less parts are required, and the anti-scattering bio-support can be made lighter by that amount. Instead, it can be easily suspended by temporarily suspending it using a simple suspending means such as a crane or a chain block.

According to the anti-scattering curing system according to the present invention and the structure dismantling method using the system, the anti-scattering biosupport has a vertical support structure located outside a predetermined portion of the opposite outer wall of the target structure. It is installed and does not cover the entire top floor of the target structure, and even if a plurality of anti-scattering biosupports are provided, they are provided so as to be separated from each other by a predetermined distance between the adjacent anti-scattering biosupports. If necessary, open the space between the adjacent shatterproof nutrient supports by partially sliding the shatterproof nutrient, and use a crane or the like separately provided through the opened part to dismantle the materials. It is possible to carry in and out equipment and equipment.

Next, a specific example of the form for carrying out the shatterproof curing system according to the present invention and the structure dismantling method using the same will be described in detail with reference to the drawings.
FIG. 1 is a diagram schematically showing the configuration of a shatterproof curing system according to an embodiment of the present invention from the front and side surfaces, and FIG. 2 is a diagram schematically showing a configuration of a shatterproof curing system according to an embodiment of the present invention. It is a plan view.
In FIG. 1, FIG. 1A is a view seen from the front side of the target structure to be demolished, and FIG. 1B is a view seen from the side surface side. In FIGS. 1 (a) and 1 (b), the outer wall, scaffolding, soundproof panel, etc. of the target structure located on the front side are omitted. Further, in FIG. 2, only a part of the anti-scattering body covering the upper part is shown to make the figure easier to see.

Referring to FIGS. 1 and 2, the shatterproof curing system 1 according to the embodiment of the present invention includes a pair of vertical support structures 14 formed on the outside of a predetermined portion of the facing outer wall 101 of the object structure 100 to be dismantled. To cover the upper part of the target structure 100 from the upper part of the anti-scattering biosupport 10 and the anti-scattering biosupport 10 having the upper support 15 spanning the uppermost part of the paired vertical support structure 14. It has a shatterproof curing body 20 provided in the above. Further, around the target structure 100, a scaffold 50 configured to surround the outer periphery of the outer wall 101 and the vertical support structure 14 and a soundproof panel 25 attached to the outer peripheral side of the scaffold 50 are provided.

When dismantling the target structure 100, in order to ensure the safety of the surroundings during the dismantling work, it is necessary to cover the periphery and the upper part of the target structure 100 with a shatterproof nutrient body 20 such as a sheet or a net. The scaffolding 50 and the soundproof panel 25 may be removed in sequence as the structure 100 is dismantled from the upper floors. However, the anti-scattering organism 20 that covers the upper part of the target structure 100 needs to be sequentially lowered in accordance with the dismantling of the target structure 100. Therefore, although not shown in FIGS. 1 and 2, the shatterproof curing system 1 according to the embodiment of the present invention temporarily lowers the shatterproof curing body 20 due to the dismantling of the target structure 100. Further provided is a suspending means for suspending the body support 10.

The shatterproof curing system 1 according to the embodiment of the present invention has a relatively lightweight and inexpensive configuration without installing a construction elevator for lowering the shatterproof curing body 20 by using a hanging means. It is possible to realize a structure dismantling method that can be easily replaced. The rearrangement will be described later with reference to FIG. 7.

The shatterproof curing system 1 of FIG. 1 shows an embodiment in which the vertical support structure 14 is constructed from the ground. The vertical support structure 14 is a vertically stacked basic structure 13 including a plurality of columnar members 11 erected in the vertical direction and a plurality of horizontal members 12 for connecting the plurality of columnar members 11 in the horizontal direction. To form. In the embodiment, in addition to the horizontal member 12, a basic structure 13 in which the columnar members 11 are combined in a square columnar shape as a whole by four columnar members 11 is used, including a brace that connects the columnar members 11 in an oblique direction. Such a basic structure 13 is also called a box truss, and standardized materials having different lengths are distributed as sales or rental members, and the basic structure 13 uses such a distributed box truss. May be good. The vertical support structure 14 formed by stacking a plurality of basic structures 13 in the vertical direction may be formed by stacking one type of basic structure 13, but in one embodiment, the basic structures 13 having different lengths are used in combination. do.

The stacked basic structures 13 are connected to each other by fastening the flange portions provided at the ends of the columnar members 11 with bolts and nuts. The basic structure 13 installed on the ground, which is the lowermost end of the vertical support structure 14, is adjusted and fixed so that all of the plurality of columnar members 11 are properly grounded by using a jack base or the like.

The vertical support structure 14 is formed vertically along the outer wall 101 of the target structure 100, but when the height of the vertical support structure 14 is high, such as when the target structure 100 is in a high level, the target structure is formed. A reinforcing member which is attached to the outer wall 101 of 100 and supports the vertical support structure 14 may be provided.

As shown in FIG. 2, a scaffold 50 is installed on the outer periphery of the target structure 100, and a soundproof panel 25 is further installed on the outer periphery of the scaffold 50. The soundproof panel 25 prevents noise during the dismantling work from leaking to the outside, and also prevents dismantled objects such as concrete pieces and dust generated by the dismantling from scattering to the outside. Although the soundproof panel 25 is used in FIGS. 1 and 2, a soundproof sheet may be used instead of the soundproof panel 25. Since the vertical support structure 14 is installed outside the predetermined portion of the opposite outer wall 101 of the target structure 100, if the scaffold 50 is provided further outside the vertical support structure 14, the scaffold 50 is located between the scaffold 50 and the outer wall 101. The distance is too wide, which reduces workability and is not preferable in terms of safety. Further, the scaffolding 50 may be provided by projecting only the portion where the vertical support structure 14 is installed so as to avoid it to the outside, but the structure of the scaffolding 50 becomes complicated and the installation of the soundproof panel 25 is hindered. ..

Therefore, in the shatterproof curing system 1 according to the embodiment of the present invention, the scaffolding 50 is installed along the outer wall 101 of the target structure 100 at a constant separation distance from the outer wall 101, and the portion where the vertical support structure 14 is installed is shown in the figure. As will be described later with reference to 4, the scaffolding 50 is prevented from partially protruding outward while securing a passage by narrowing the installation width of the steel cloth plate of the scaffolding 50.

FIG. 1A shows a state in which six pairs of vertical support structures 14 are installed so as to be paired on the front side and the back side of the target structure 100. As shown in FIG. 1 (b), the upper support 15 is bridged over the uppermost portions of the vertical support structures 14 on the front side and the back side of each pair. A pair of vertical support structures 14 and an upper support 15 form one shatterproof biosupport 10. The upper support 15 may be an integral structure, but in the embodiment, the basic structure 13 is connected and configured like the vertical support structure 14. The upper support 15 may also be used in combination with box trusses of various dimensions that are in circulation.
In FIG. 1 (b), the upper support 15 is shown to have a horizontal beam-like shape, but the upper support 15 plays a role of supporting the shatterproof nutrient body 20 and has a gable roof. It may have a mountain-shaped shape like this.

When a plurality of anti-scattering biosupports 10 are installed, each of the anti-scattering biosupports 10 may be installed independently, but in one embodiment, adjacent anti-scattering biosupports 10 are connected to each other. By connecting with 16 and forming a combined structure supported by four vertical support structures 14, the structure is resistant to external forces in the horizontal direction.

Further, when a plurality of anti-scattering biosupports 10 are installed, at least a pair of adjacent anti-scattering biosupports 10 are installed at a distance L by a predetermined distance. This is to secure a work space necessary for lifting the heavy machinery 60 and equipment necessary for dismantling the target structure 100 on the roof with a crane (not shown) and removing large dismantling members. Is. In one embodiment, the predetermined distance L is 12 m. However, the predetermined distance L can be appropriately changed depending on the size of the target structure 100 to be dismantled, the type of the heavy machine 60 to be used, and the like, and may be larger or smaller than 12 m.

Further, in one embodiment, a guide rail or a guide wire for the anti-scattering organism 20 is laid on the upper support 15, and the anti-scattering organism 20 slides along the guide rail or the guide wire to be whole or partially. During the dismantling work, the shatterproof cage 20 is closed to prevent the scattering of debris generated during dismantling, and the shatterproof cage 20 is used only when it is necessary to lift or carry it out. Open and work.

Since the target structure 100 is dismantled in order from the upper floors to the lower floors using a heavy machine 60 or the like, the vertical support structure 14 is used to secure an operating area for the heavy machine 60 at the time of dismantling. It is formed by stacking up to a height higher than the top floor of the target structure 100 and a height that can secure a work space required for dismantling the top floor of the target structure 100. In one embodiment, the vertical support structure 14 is formed so as to secure a working space at a height of about 9 m from the floor surface of the floor on which the heavy equipment 60 works.

FIG. 3 is an enlarged view showing the structure of the shatterproof curing system according to the embodiment of the present invention near the ground.
Referring to FIG. 3, a vertical support structure 14 in which the basic structures 13 are stacked from the ground is formed along the outer wall 101 of the target structure 100, and a scaffold 50 is formed on the outside of the vertical support structure 14. When viewed from the horizontal direction along the outer wall 101, the vertical support structure 14 and the scaffold 50 partially overlap each other. With such a configuration, the distance between the scaffold 50 and the outer wall 101 can be suppressed. In one embodiment, the distance from the outer wall 101 to the center of the inner columnar member 11 of the vertical support structure 14 is 100 mm, the distance from the outer wall 101 to the center of the outer columnar member 11 is 600 mm, and the distance from the outer wall 101 to the scaffolding 50. The distance between the two is 400 mm.

The scaffolding 50 uses a general building frame scaffolding 50 in which the building frames 51 are connected by a brace 53 and a steel cloth plate 52 is laid over the two building frames 51 to be assembled. The soundproof panel 25 is attached to the leg portion on the outer peripheral side of the building frame 51 via the curing clamp 55. In the embodiment, for the scaffolding 50 provided in the portion where the vertical support structure 14 is installed, the width for installing the steel cloth plate 52 spanning the two building frames 51 is made narrower than the other portions. It prevents the scaffolding 50 and the vertical support structure 14 from interfering with each other.

FIG. 4 is an enlarged plan view showing an intermediate height portion of the anti-scattering curing system according to the embodiment of the present invention.
Referring to FIG. 4, the vertical support structure 14 is composed of regular tetrahedrons in which columnar members 11 stand at four corners of a square. In the scaffolding 50, in the portion where the vertical support structure 14 is not provided, braces 53 are attached to both sides of the adjacent building frame 51 by a normal assembly method, and a steel cloth plate 52 is installed on the upper surface of the building frame 51. .. In the part where the vertical support structure 14 is installed, the brace 53 is normally attached to the outer peripheral side of the building frame 51 sandwiching the vertical support structure 14, but the inner peripheral side is passed through the inside of the vertical support structure 14. Attach the brace 53. However, since the basic structure 13 constituting the vertical support structure 14 is provided with the horizontal member 12 and the brace, the horizontal member 12 and the brace interfere with each other and the brace 53 cannot be installed depending on the location. In such a case, instead of the brace 53 that diagonally connects the adjacent building frames 51, a reinforcing material that horizontally connects the upper portions of the adjacent building frames 51 is installed. However, if neither the brace 53 nor the reinforcing material for horizontally connecting the brace 53 can be installed, the scaffolding wall connection described later may be installed to reinforce the brace 53, and these may be omitted.

Further, at least in the portion where the vertical support structure 14 is installed, the installation width of the steel cloth plate 52 is reduced as compared with the scaffolding 50 in the other portion. Specifically, the steel cloth plate 52 having a narrower width than the other parts is used, or when the steel cloth plate 52 is composed of a plurality of pieces, the number of sheets to be installed is reduced from the other parts so as to be perpendicular to the scaffolding 50. Prevents interference with the support structure 14. However, although the installation width of the steel cloth plate 52 is narrow, about two-thirds of the passage width remains in the arrangement as shown in FIG. 4, which is a sufficient width for passage. Since the scaffolding 50 and the vertical support structure 14 are installed so as not to interfere with each other, they are independent of each other. It becomes easy to partially remove the basic structure 13 without adding it.

In the scaffolding 50 corresponding to the portion where the vertical support structure 14 is installed in this way, the brace 53 may not be partially installed and the installation width of the steel cloth plate 52 is small. The strength is lower than that. Therefore, in the embodiment, a scaffolding wall connecting 54 that is fixed to the outer wall 101 to reinforce the scaffolding 50 is installed on at least one of the building frames 51 adjacent to the vertical support structure 14. The scaffolding wall connecting 54 may be fixed to the building frame 51 for each step, or may be provided for every several steps of the building frame 51.

FIG. 5 is a diagram schematically showing the configuration of a shatterproof curing system according to another embodiment of the present invention from the front and side surfaces. FIG. 5A is a view seen from the front side of the target structure to be demolished, and FIG. 5B is a view seen from the side surface side. In FIGS. 5 (a) and 5 (b), the scaffolding, the soundproof panel, and the like located on the front side are omitted. The outer wall located on the front side also shows only the position of the opening.

Referring to FIG. 5, the shatterproof curing system 2 according to another embodiment of the present invention includes a pair of vertical support structures 14 formed on the outside of a predetermined portion of the facing outer wall 101 of the object structure 100 to be dismantled. An anti-scattering biosupport 10 including an upper support 15 spanning the uppermost part of the paired vertical support structure 14 and an upper portion of the anti-scattering biosupport 10 to cover the upper part of the target structure 100. It has a shatterproof curing body 20 provided in the above. In this respect, the shatterproof curing system 2 is similar to the shatterproof curing system 1 shown in FIG. The shatterproof curing system 2 differs from the shatterproof curing system 1 in that the vertical support structure 14 is constructed from the ground in the shatterproof curing system 1, whereas the shatterproof curing system 2 is from the middle floor to the upper part. It is a point that is formed only. Therefore, the shatterproof curing system 2 includes an intermediate support 30 projecting to the outside of the outer wall 101 through the opening in the opening of the intermediate floor of the target structure 100.

In the embodiment shown in FIG. 5, the intermediate support 30 is installed on the floor below the top floor on which the heavy equipment 60 works, and the vertical support structure 14 is located on the top floor of the target structure 100 from above the intermediate support 30. It is formed by stacking up to a height that can secure the work space required for dismantling.
The vertical support structure 14 stacked on the intermediate support 30 is the same as the anti-scattering curing system 1 shown in FIG. 1, and is at least a predetermined distance L between a pair of adjacent anti-scattering biosupports 10. Since the configuration such as separation does not change, explanations that overlap with the contents described in the shatterproof curing system 1 will be omitted.

FIG. 6 is an enlarged view showing the vicinity of the outer wall opening of the shatterproof curing system according to another embodiment of the present invention. FIG. 6A is a view seen from the front side of the target structure to be demolished, and FIG. 6B is a view seen from the side surface side.
Referring to FIG. 6, the intermediate support 30 has a wall fixing member 31 for fixing a position in a direction orthogonal to the outer wall 101 so as to sandwich the outer wall 101, and a horizontal direction so as to abut against the left and right walls of the opening of the outer wall 101. It is provided with an opening frame fixing member 32 that is installed in the outer wall 101 and fixes a position in a direction parallel to the outer wall 101, and an overhanging support member 33 that projects outside the outer wall 101.

The vertical support structure 14 is mounted on the overhanging support member 33. A scaffold 50 is formed on the outside of the vertical support structure 14. The scaffold 50 is constructed from the ground, and in this case as well, the vertical support structure 14 and the scaffold 50 partially overlap when viewed from the horizontal direction along the outer wall 101, similar to the shatterproof curing system 1 shown in FIG. Therefore, in the scaffolding 50 corresponding to the position where the vertical support structure 14 is provided in the shatterproof curing system 2, as in the shatterproof curing system 1, the horizontal members 12 and the braces of the basic structure 13 constituting the vertical support structure 14 are formed. If installation is difficult due to interference, the brace 53 on the inner peripheral side is omitted, the installation width of the steel cloth plate 52 is narrowed, and the scaffolding wall joint 54 is installed to reinforce the structure.

On the other hand, in the shatterproof curing system 2, since there is no vertical support structure 14 below the intermediate support 30, the scaffold 50 located below the intermediate support 30 is a scaffold in a portion without the vertical support structure 14. It may be formed in the same manner as 50. However, with the dismantling of the target structure 100, the vertical support structure 14 gradually descends downward due to the refilling. Therefore, in one embodiment, the scaffolding 50 at the portion where the vertical support structure 14 descends is made of steel. The cloth plate 52 has a plurality of configurations, the brace 53 on the inner peripheral side of the scaffold 50 is omitted, and the scaffold wall connecting 54 is installed to reinforce the scaffold plate 52. With such a configuration, when the vertical support structure 14 is refilled, the refilling work can be proceeded only by removing the steel cloth plate 52 on the inner peripheral side that interferes with the vertical support structure 14. ..

FIG. 7 is a diagram for explaining a method for lowering the anti-scattering curing body according to the embodiment of the present invention, and is an explanatory diagram of the anti-scattering curing system 1 in which the vertical support structure 14 is constructed from the ground. FIG. 7 (a) is a diagram showing a state in which the wall of the top floor is laid down, FIG. 7 (b) is a diagram showing a state in which a heavy machine is lowered to the lower floor and a hollowed-out dismantling is performed, and FIG. 7 (c) is a diagram. It is a figure which shows the state which refills the anti-scattering body 20 before the wall is knocked down.

Referring to FIG. 7A, the heavy machine 60 is installed on the 9th floor of the target structure 100, the rooftop part is dismantled and the 9th floor part is hollowed out, and the wall of the 9th floor part outer wall 101 is completed. The state of defeating is shown. The scaffolding 50 is provided up to a height at which two steps protrude upward from the rooftop, and a soundproof panel 25 is installed on the outer periphery of the scaffolding 50. Further, between the scaffold 50 and the outer wall 101, the anti-scaffolding body support 10 is installed higher than the scaffolding 50 to support the anti-scaffolding body 20. During the dismantling work, the soundproof panel 25 and the anti-scattering body 20 prevent the scattering of concrete pieces and dust around the target structure 100.

When the wall of the outer wall 101 on the 9th floor has been laid down, the heavy equipment 60 is lowered onto the floor on the 8th floor, which is the lower floor, and the floor on the 9th floor is dismantled and inside the 8th floor, as shown in FIG. 7B. Dismantling is proceeding. The upper part of the scaffolding 50 is removed as the outer wall 101 of the 9th floor is laid down, but the anti-scaffolding body support 10 and the anti-scaffolding body 20 are maintained as they are.

Referring to FIG. 7C, a crane 41, which is a hanging means 40, temporarily suspends a portion of the shatterproof biosupport 10 from at least the uppermost portion to a predetermined height by a crane 41, which is a hanging means 40, before the wall of the outer wall 101 of the 8th floor is laid down. Suspend and refill. In the case of the anti-scattering curing system 1 for constructing the vertical support structure 14 from the ground, it is necessary to remove any one of the basic structures 13 constituting the vertical support structure 14 in order to lower the anti-scattering curing body 20. .. Therefore, for example, when the basic structure 13 is removed as shown by the arrow A in FIG. 7 (c), the portion of the basic structure 13 directly above the basic structure 13 to be removed is removed from at least the uppermost portion of the anti-scattering biosupport support 10. The basic structure 13 is removed in a temporarily supported state. Next, the suspended shatterproof biosupport 10 is lowered by the crane 41, connected to the basic structure 13 at the top of the vertical support structure 14 erected from the ground, and then the suspension by the crane 41 is released. do.

In this way, the hanging means 40 is temporarily used only during the refilling. The crane 41 as the suspending means 40 may be installed outside the target structure 100, or may be installed on a support column provided so as to penetrate the floor surface of the target structure 100. Further, a chain block may be used for the hanging means 40. There is a concern that the scaffolding 50 installed around the target structure 100 is insufficient in strength to constantly support the anti-scattering biosupport support 10, but it is possible to temporarily support it. Therefore, a chain block may be attached to the scaffold 50 to support the shatterproof biosupport 10 only during the refilling.

The basic structure 13 to be removed at the time of refilling may be of any height, but the closer to the ground floor, the heavier the weight of the anti-scattering biosupport 10 that temporarily supports it, so the work floor being dismantled It is preferable to remove the basic structure 13 having a height close to. Further, if the height of the first floor of the target structure 100 and the height of the basic structure 13 are the same, the basic structure 13 may be removed by one step and refilled with the dismantling of one floor. When the heights are different, the relationship between the heights of the target structure 100 and the shatterproof biosupport 10 gradually shifts as the dismantling progresses to the lower floors. Therefore, in one embodiment, a vertical support structure 14 is used in which basic structures 13 having different lengths are combined and stacked so as to be close to the height of the first floor of the target structure 100, and the target structure 100 at the time of refilling is used. Adjust so that the relationship between the height of the shatterproof nutrient support 10 and the height of the shatterproof nutrient support 10 remains within a certain range.

By repeating the work shown in FIGS. 7 (a) to 7 (c) and proceeding with the dismantling work from the upper floors to the ground floor, the target is to prevent dismantled objects such as concrete pieces and dust from scattering to the outside. The structure 100 can be dismantled.

In the case of the anti-scattering curing system 2 in which the vertical support structure 14 is formed only from the middle floor to the upper part, the anti-scattering biological support 10 formed from above the intermediate support 30 is temporarily suspended by the suspending means 40. After moving the intermediate support 30 to the lower floor, the shatterproof biosupport 10 is lowered and fixed to the intermediate support 30 again to perform the refilling. In this case as well, the crane 41 or the chain block can be used as the suspending means 40.

FIG. 8 is a flowchart for explaining a structure dismantling method using the shatterproof curing system according to the embodiment of the present invention, and is a diagram for explaining a structure dismantling method in the shatterproof curing system 1 shown in FIG. be.
Referring to FIG. 8, a plurality of columnar members 11 and a plurality of columnar members 11 vertically erected outside a predetermined portion of the facing outer wall 101 of the target structure 100 to be dismantled in step S800 are horizontally arranged with each other. After forming at least a pair of vertical support structures 14 by vertically stacking a plurality of basic structures 13 composed of a plurality of horizontal members 12 to be connected, the target structure 100 is placed on the uppermost portion of at least the pair of vertical support structures 14. An upper support 15 that supports the anti-scattering organism 20 that covers the upper portion is bridged over to form the anti-scattering organism support 10.

The vertical support structure 14 is formed by stacking from the ground to a height higher than the top floor of the target structure 100 so as to secure a work space required for dismantling the top floor of the target structure 100. Further, when a plurality of shatterproof biosupports 10 are formed, at least a predetermined distance between a pair of adjacent shatterproof biosupports 10 so that the heavy machine 60 and the equipment can be lifted and the disassembled members can be removed. Install only apart.

After the anti-scattering biosupport 10 is installed, the top floor of the target structure 100 is covered with the anti-scattering biosupport 20 from above the anti-scattering biosupport 10 in step S810. The shatterproof nutrient body 20 includes a sheet or a net, or a combination structure thereof. The anti-scattering organism 20 covers the upper part of the target structure 100 from above the anti-scattering organism support 10, but the heavy machinery 60 and equipment are used in the portion of the anti-scattering organism support 10 installed at a predetermined distance. It is preferable to provide a guide rail for opening and closing, or a window that can be partially opened and closed so that the opening and closing can be easily performed when the parts are lifted or the disassembled member is removed.

At step S820, the top floor of the target structure 100 is dismantled. Here, the top floor does not mean a fixed top floor like the 9th floor of a 9-story building, but the height of the target structure 100 becomes lower due to the progress of demolition, but at that time it becomes the top floor. It is the floor on which it is located. At this time, for example, when dismantling the roof of a 9-story building or hollowing out the 9th floor as shown in FIGS. 6 (a) and 6 (b), the heavy machine 60 is installed on the floor surface of the 9th floor, and 9 When dismantling the floor surface of the floor or hollowing out the 8th floor, the heavy machine 60 is installed on the floor surface of the 8th floor.

After the dismantling of the top floor is completed, the shatterproof biosupport 10 above the middle part is hung by the hanging means 40 in step S830 for refilling. More specifically, since the vertical support structure 14 of the anti-scattering bio-support 10 is stacked and fixed from the ground, the suspending means 40 supports the anti-scattering bio-support 10 above the intermediate portion. Then, by removing the bolts and nuts on the upper side of the basic structure 13 to be removed and releasing the fixing, the shatterproof biosupport 10 above the basic structure 13 to be removed is suspended.

In step S840, the basic structure 13 in several stages below from the middle part is removed. If the basic structure 13 to be removed for refilling is equivalent to the height of the first floor of the target structure 100, it is sufficient to remove only one step, but the height of the basic structure 13 is the target structure. If the height is lower than the height of the first floor of the object 100, several steps equivalent to the height of the first floor of the target structure 100 are removed. If a reinforcing member attached to the outer wall 101 to support the vertical support structure 14 is connected to the basic structure 13 to be removed, the reinforcing member is also removed.

Next, in step S850, the shatterproof biosupport 10 above is lowered from the suspended intermediate portion, and is connected to the basic structure 13 at the top of the vertical support structure 14 erected from the ground. Release the suspension from.
Based on the determination result of step S860, the above steps S820 to S850 are repeated until the ground floor, and when the dismantling to the ground floor is completed in step S860, the dismantling of the target structure 100 is completed.

In the above, the structure dismantling method has been described focusing on the installation of the anti-scaffolding body support 10 and the anti-scaffolding body 20 and the point of lowering and changing the anti-scaffolding body 20 according to the progress of the dismantling work. However, in the embodiment, the scaffolding 50 and the soundproof panel 25 are installed so as to surround the outer periphery of the target structure 100 and the vertical support structure 14 in parallel with the step S800. At this time, in the portion where the vertical support structure 14 is installed, the brace 53 of the scaffolding 50 is partially omitted, the installation width of the steel cloth plate 52 is narrowed, or the scaffolding wall joint 54 is installed. As explained with reference.
Further, in the embodiment, the scaffolding 50 and the soundproof panel 25 installed around the top floor where the dismantling is completed between the stage S820 and the stage S830 are removed.

FIG. 9 is a flowchart for explaining a structure dismantling method using the shatterproof curing system according to another embodiment of the present invention, and is for explaining the structure dismantling method in the shatterproof curing system 2 shown in FIG. It is a figure of.
Referring to FIG. 9, in step S900, the intermediate support 30 is installed in the opening of the outer wall 101 on the intermediate floor of the target structure 100. The intermediate support 30 includes an overhanging support member 33 that projects outside the outer wall 101.

In step S910, after forming a pair of vertical support structures 14 on the intermediate support 30, an upper support 15 is laid over the uppermost part of the vertical support structure 14 to form a shatterproof biosupporting support 10. do. The anti-scattering biosupport 10 formed in step S810 of FIG. 8 is constructed from the ground, whereas the anti-scattering biosupport 10 formed in step S910 of FIG. 9 is the intermediate support 30 installed on the intermediate floor. The formation method and structure are the same from the middle floor to the upper side, only the point of formation on the top is different.
After forming the anti-scattering support 10 is formed, the top floor of the target structure 100 is covered with the anti-scattering support 20 from above the anti-scattering support 10 in step S920.

After dismantling the top floor of the target structure 100 in step S930, the anti-scattering biosupport 10 is suspended on the intermediate support 30 by the suspending means 40 in step S940. Also in more detail, after the anti-scattering biological support 10 on the intermediate support 30 is supported by the suspending means 40, the bolts and nuts of the connecting portion with the intermediate support 30 are removed and fixed. By releasing the above, the anti-scattering body support 10 is suspended. The suspending means 40 at this time may be a crane 41 or a chain block.

While the shatterproof biosupport 10 is temporarily suspended by the suspending means 40, the intermediate support 30 is removed in step S950 and refilled on the lower floor. In one embodiment, a plurality of intermediate supports 30 are prepared, and a new intermediate support 30 is installed on the lower floor in advance, thereby shortening the time for temporarily suspending the anti-scattering biosupport support 10. ..

Then, in step S960, the suspended shatterproof biosupport 10 is lowered and fixed again to the refilled intermediate support 30.
Based on the determination result of step S970, the above steps S930 to S960 are repeated, and when the intermediate support 30 reaches the ground, the remaining floors of the target structure 100 are dismantled to the ground floor in step S980 to reach the target structure. The dismantling of 100 is completed.

Although not shown in the flowchart in the case of FIG. 9, the scaffolding 50 and the soundproof panel 25 are constructed in parallel with the stage S910, and the scaffolding 50 and the scaffolding 50 located around the dismantling end portion due to the dismantling of the target structure 100. The point that the soundproof panel 25 is sequentially removed is the same as the structure dismantling method described with reference to FIG.

Although the embodiments of the present invention have been described in detail with reference to the drawings, the present invention is not limited to the above-described embodiments and is variously modified within the range not departing from the technical scope of the present invention. It is possible to do.
