Description

  The present invention relates to a building repair / dismantling apparatus and a building repair / dismantling method, and more particularly, a building repair / dismantling for repairing or dismantling a building constructed using an asbestos-containing material on the outer peripheral side including a curtain wall. The present invention relates to an apparatus for building and a method for repairing / dismantling a building.

  Conventionally, curtain walls have been widely used as non-bearing walls (outer walls) such as medium- and high-rise buildings because they have many advantages such as high degree of freedom in design and efficiency in construction. Yes. On the other hand, in Japan, buildings that use curtain walls have been actively built since the 1960s, and buildings using such curtain walls also need to be refurbished / disassembled due to deterioration over time. It is coming.

  And as a method of dismantling this kind of building, a tower is set up in the elevator hall that penetrates inside the building, and waste materials are suspended on the ground with a mast climbing crane, and the building is dismantled sequentially from the upper floor. A method has been proposed and put into practical use (for example, see Patent Document 1).

JP 2007-297867 A

  By the way, as a structural feature of the curtain wall (for the purpose of ensuring fire resistance and sound absorption of the building constructed using the curtain wall, prevention of condensation, etc.), for example, a support member on the back side of the curtain wall (inside the building) It is necessary to apply a fireproofing treatment (such as steel beams and fasteners) or to fill an interlayer sealing material between the back surface of the curtain wall and the slab. From the 1960s to around 1980, asbestos-containing spray materials (asbestos) were used for the back spray material of the waist panel (curtain wall), the fire-resistant coating material for steel beams, the interlaminar plugging material, the fire-resistant coating material for fasteners, and the inner side plate backing material. Containing material, asbestos) was used.

  For this reason, it is required to remove the asbestos-containing material in advance when refurbishing the curtain wall of this type of building or dismantling the building, but the asbestos used on the outer peripheral side of the building including the curtain wall There are many cases where the contained material cannot be completely removed. Thereby, for example, when the dismantling method as disclosed in Patent Document 1 is adopted, there is a possibility that asbestos is scattered outside. In particular, in a high-rise building exceeding 70 m, it is difficult to build a total scaffold on the outer periphery (outside) of the building and isolate the work area. For this reason, there has been a strong demand for a method that can reliably prevent the asbestos from being scattered during the renovation / demolition of a building.

  In view of the circumstances described above, an object of the present invention is to provide a building renovation / demolition apparatus and a building refurbishment / demolition method that can reliably prevent asbestos from being scattered and renovate or dismantle a building. To do.

  In order to achieve the above object, the present invention provides the following means.

  The building renovation / demolition apparatus according to the present invention is a building renovation / demolition apparatus for refurbishing or demolishing a building constructed using an asbestos-containing material on the outer peripheral side including the curtain wall. It is formed with a side wall, a roof part above, a floor part below, an opening on the other side, and a height greater than the maximum floor height of the building, and provided at the top of the building An outer body that is suspended and supported by a crane and is installed outside the building so that the opening faces the outer periphery, a negative pressure dust removing device that sucks air inside the outer body, and the opening In the state where the outer body is installed so as to face the outer peripheral portion, elasticity provided to be able to advance and retreat from the end of the roof portion and / or the floor portion forming the opening portion toward the outer peripheral portion. It is characterized by comprising To.

  In the present invention, when the curtain wall is repaired or the building is dismantled, the outer wall is opened to the outer periphery of the predetermined floor where the curtain wall and the asbestos-containing material (asbestos) are removed by the crane provided at the top of the building. While installing so that a part may oppose, an elastic member is advanced and it adheres to an outer peripheral part. At this time, since the outer body is formed to have a height greater than the maximum floor height of the building, the elastic members that have advanced from the ends of the roof portion and the floor portion respectively sandwich, for example, the upper floor. The curtain wall and the curtain wall of the lower floor are in contact with each other and closely contact each other, and the gap between the roof, the edge of the floor and the outer periphery of the building can be closed with an elastic member (the inside and outside of the outer body are It can be partitioned and made discontinuous by an elastic member). Moreover, the inside of an outer body can be made into a negative pressure state by attracting | sucking the internal air of an outer body with a negative pressure dust removal apparatus.

  And the curtain wall of a predetermined floor can be removed and the asbestos (asbestos containing material) of the outer peripheral part side of a building can be removed by the operator who entered the inside of an outer shell. Further, at this time, the gap is closed by the elastic member, and the inside of the outer body is held in a negative pressure state by the negative pressure dust removing device, and asbestos scattered in the outer body is collected. For this reason, the asbestos used for the outer peripheral part side of the building which was difficult to remove completely in the past can be reliably prevented from being scattered outside and removed. In addition, by moving the building renovation / demolition device with a crane and removing another curtain wall and asbestos while reliably preventing the asbestos from being scattered in the same manner as described above, the elastic member is retracted and the building renovation / demolition device is moved. It will be possible to install a new curtain wall using a dismantling device, repair the curtain wall, or dismantle the building.

  In the building renovation / dismantling apparatus of the present invention, it is desirable that the outer body is formed in an annular shape so as to surround the building.

  In this invention, since the outer body is formed in an annular shape so as to surround the building, the outer body (building repair / dismantling device) suspended and supported by the crane is less affected by wind pressure and the like, and is stable. It can be installed on a predetermined floor of the building in a state.

  Furthermore, in the building renovation / dismantling apparatus of the present invention, the one side opening / closing plate portion is formed in a U-shaped cross section and has a larger length than the other side base end plate portion. The upper floor isolation hood is formed, and the upper floor isolation hood is connected to the roof portion so that the distal end of the base end plate portion can be rotated. It is desirable that the front end side is configured to be in close contact with the outer peripheral portion.

  In the present invention, the inside and the outside of the outer body can be surely partitioned and made discontinuous by the upper floor isolation hood. That is, for example, if the curtain wall and asbestos on each floor from the upper floor to the lower floor are to be removed sequentially while hanging the outer body (building repair / dismantling device) from the upper floor to the lower floor with a crane, remove it. There is a possibility that the curtain wall on the upper floor is already removed from the predetermined floor where the curtain wall is located, and the elastic member advanced from the end of the roof part cannot be tightly adhered to the outer peripheral part (upper curtain wall) to close the gap There is. On the other hand, when the upper floor isolation hood is provided, the upper floor isolation hood is rotated by bringing the front end side of the opening and closing plate portion into close contact with, for example, the upper floor slab (outer peripheral portion). Thus, the inside and outside of the outer body can be reliably partitioned and made discontinuous. Thereby, it can prevent reliably that asbestos is scattered outside through the clearance gap between the edge part of a roof part, and the outer peripheral part of a building.

  The building refurbishment / dismantling method of the present invention is a method of repairing or dismantling a building constructed using asbestos-containing material on the outer peripheral side including the curtain wall, and installing a crane at the top of the building And a partition wall that divides the outer peripheral side and the inner side of the building, and the outer body of the building repair / dismantling device according to any one of the above, with the opening facing the outer peripheral part Installed by hanging and supporting with a crane, the elastic member is advanced from the end of the roof and / or the floor, and is brought into close contact with the outer periphery, and / or the upper floor isolation hood is rotated. The opening and closing plate part is closely attached to the outer peripheral part to partition the inside and outside of the outer body, and the air inside the outer body is sucked by the negative pressure dust removing device and the inside of the outer body is In a negative pressure state, Characterized in that so as to remove the over ten wall and said asbestos-containing material.

  In the present invention, it is possible to surely obtain the effect of the above-mentioned building renovation / dismantling apparatus.

  According to the building repair / dismantling apparatus and the building repair / dismantling method of the present invention, the elastic member closes the gap between the end of the roof or floor and the outer periphery of the building. Because the asbestos scattered inside the outer body is collected while the inside of the outer body is held in a negative pressure state by the dust remover, it was used on the outer peripheral side of the building, which was difficult to remove completely in the past. Asbestos can be reliably removed and prevented from being scattered outside. In addition, by moving the building repair / dismantling device with a crane and removing another curtain wall and asbestos while reliably preventing the asbestos from being scattered, the building repair / It will be possible to install a new curtain wall using a demolition device, repair the curtain wall, or demolish the building.

  In addition, when a curtain wall is refurbished using this building refurbishment / dismantling device, a new curtain wall having an energy saving function is installed, and at the same time as the curtain wall is renovated, seismic renovation and equipment renovation are performed. It is possible. For this reason, it is possible to make the building earthquake-proof and energy-saving by using the building renovation / demolition device simultaneously with the renovation of the curtain wall.

The inside of the outer casing 1 on the working chamber 12 side is brought into a negative pressure state with respect to the outside.

  Next, a method for repairing the building T by using the building repair / dismantling apparatus A having the above-described configuration, removing the curtain wall 15 and removing the asbestos-containing spray material used on the outer peripheral portion T1 side of the building T. While explaining, the operation | movement and effect of the building repair / dismantling apparatus A and the building repair / dismantling method of this embodiment are demonstrated.

  When repairing the curtain wall 15 of the building T using the building repair / dismantling apparatus A of the present embodiment, first, the crane 10 is installed on the uppermost portion T2 of the building T. Here, when there is equipment or the like at the uppermost part T2 and the crane 10 cannot be installed as it is, a temporary slab 20 is constructed on the uppermost part T2 as shown in FIGS. The crane 10 is installed on the slab 20.

  Further, as shown in FIG. 2, a work yard 21 is constructed on the ground G in the vicinity of the building T, and the outer body 1 (building repair / dismantling apparatus A) is grounded so as to surround the building T. Furthermore, as shown in FIG.1 and FIG.4, the partition wall 22 for partitioning the outer peripheral part T1 side and the building interior T3 side is built in the inside of the building T of the predetermined floor which repairs the curtain wall 15. As shown in FIG. Then, as shown in FIGS. 1 and 2, the building repair / dismantling apparatus A (outer body 1) is lifted by using a crane 10 installed at the uppermost part T <b> 2 of the building T, and the curtain floor 15 is repaired. To place. At this time, the building renovation / dismantling apparatus A is arranged so that the roof 1b is arranged on the upper floor side and the floor 1c is arranged on the lower floor side across the predetermined floor to be repaired.

  Next, as shown in FIG. 1, the hydraulic cylinders 2 and 3 disposed on the roof portion 1b and the floor portion 1c of the outer body 1 are extended to form hollow rubbers 4 and 5 provided at the tips of the curtain walls on a predetermined floor. 15 is closely attached to the curtain wall 15 on the upper floor and the curtain wall 15 on the lower floor. At this time, when the curtain wall 15 on the upper floor is already removed with the predetermined floor in between, the winch 18 provided on the roof portion 1b is driven to rotate the upper floor isolation hood 6, and the opening / closing plate portion The rubber 17 on the tip side of 6a is brought into close contact with the slab 23 on the upper floor. Accordingly, the hollow rubber 4 and 5 in which the inside of the outer body 1 is in close contact with the curtain wall 15 (outer peripheral portion T1) on the upper and lower floors, or the hollow rubber 5 and upper floor in close contact with the lower curtain wall 15 (outer peripheral portion T1). Sealed by an isolation hood 6. In addition, the inside of the outer body 1 is sealed in this way, and the fall prevention member 24 is installed between the end 1e side of the floor 1c of the outer body 1 and the curtain wall 15 of the building T.

  Further, the negative pressure dust removing device 7 is driven to start the suction of the internal air of the outer body 1, and the inside of the outer body 1 on the working chamber 12 side is brought into a negative pressure state with respect to the outside. The building repair / dismantling apparatus A installed on the predetermined floor in this way is formed so as to surround the four circumferences of the building T because the outer body 1 is formed in an annular shape along the outer periphery of the building T. Therefore, it is not affected by wind pressure and is installed in a stable state. In addition, since the partition wall 22 is provided inside the building T on the predetermined floor, the wind pressure due to the chimney effect from the staircase or the like does not act on the building renovation / dismantling apparatus A, and the building is reliably stable. The repair / dismantling apparatus A will be installed.

  Next, when the building renovation / demolition apparatus A is installed on a predetermined floor as described above, an operator who enters the work room 12 of the outer body 1 removes the curtain wall 15 on the predetermined floor, and this curtain wall 15 The asbestos-containing spray material (asbestos), which has been difficult to completely remove, such as the back surface spray material, the fire-resistant coating material of the steel beam 25, the interlayer sealing material, and the fastener coating material, is sequentially removed.

  At this time, the hollow rubbers 4 and 5 close the gaps between the roof portion 1b of the outer body 1 and the end portions 1d and 1e of the floor portion 1c and the outer peripheral portion T1 of the building T, or the upper floor isolation hood. 6, the inside and outside of the outer body 1 are partitioned and made discontinuous, and the inside of the outer body 1 on the working chamber 12 side is sealed. Further, the inside of the outer body 1 is held in a negative pressure state by the negative pressure dust removing device 7, and asbestos (dust containing asbestos) scattered inside the outer body 1 is collected. Furthermore, a partition wall 22 is provided inside the building T. For this reason, asbestos is not scattered outside. Moreover, since the fall prevention member 24 is constructed between the end 1e side of the floor 1c of the outer shell 1 and the curtain wall 15 of the building T, the removed asbestos seals the floor 1c side on the hollow rubber 5 There is no such thing as falling.

  Then, the curtain wall 15 removed from the building T to remove asbestos is cleaned in the work chamber 12, and asbestos (asbestos-containing waste material) in the work chamber 12 is collected and packed, and these cleaned curtain walls 15 are collected. The asbestos packed in the container is transferred to the transfer chamber 13 by opening the opening / closing door 11a of the isolation wall 11 and using a cart with casters, or using a cart traveling on a track laid in the outer body 1. At this time, since the inside of the work chamber 12 is held in a negative pressure state by the negative pressure dust remover 7, even if asbestos remains in the work chamber 12, the open / close door 11a of the isolation wall 11 Asbestos is prevented from being scattered (leakage) into the transfer chamber 13. Then, the door 11a of the isolation wall 11 is closed, the door 14 provided on the floor 1c of the outer body 1 is opened, the curtain wall 15 cleaned with the lifting machine 16 and the packed asbestos are lowered to the ground, and the work yard Carry into 21.

  Further, a spraying material that does not contain asbestos, such as a rockwool spraying material, a rockwool sheet, a fireproof paint, etc. The new curtain wall 15 is installed by renovation using At this time, a curtain wall having an energy saving function may be used, or an earthquake-resistant repair and facility repair may be performed together. By doing so, asbestos removal (curtain wall 15 repair) is performed simultaneously with the building T. It is also possible to improve the functionality of the system (high earthquake resistance, energy saving, etc.). Here, asbestos-containing spray material (asbestos spray) may be used as the outer wall side heat insulation in the unit in fan coil units using a peri counter, etc. There is a possibility that asbestos is mixed. For this reason, it is desirable to perform such a repair of the equipment at the same time as the repair of the curtain wall 15.

  When the repair of the curtain wall 15 on the predetermined floor and the removal of asbestos are completed in this way, the hydraulic cylinders 2 and 3 are contracted to retract the hollow rubbers 4 and 5, and the outer peripheral portion T1 of the building T The close contact state is released, or the winch 18 is driven to return the upper floor isolation hood 6 to the original position, and the sealed state of the outer body 1 is released. At the same time, the building repair / dismantling apparatus A is moved to the floor where the crane wall 15 is newly repaired and the asbestos removal work is newly performed by the crane 10 installed at the uppermost portion T2, and the same operation as described above is performed. In addition, while the building repair / dismantling apparatus A is moved from the upper floor to the lower floor by the crane 10 for example, the curtain wall 15 is repaired and asbestos is removed.

  Therefore, according to the building repair / dismantling apparatus A and the building repair / dismantling method of the present embodiment, the end portions 1d and 1e of the roof portion 1b and the floor portion 1c and the outer peripheral portion T1 of the building T are formed by the hollow rubbers 4 and 5. Further, the inside of the outer body 1 is held in a negative pressure state by the negative pressure dust removing device 7 and the asbestos scattered inside the outer body 1 is collected. For this reason, asbestos used on the outer peripheral portion T1 side of the building T, which has been difficult to remove completely in the past, can be reliably prevented from being scattered to the outside. Further, the hollow rubbers 4 and 5 are evacuated and the building repair / dismantling apparatus A is moved by the crane 10 to remove another curtain wall 15 and asbestos while preventing the asbestos from being scattered in the same manner as described above. Thus, it becomes possible to install the new curtain wall 15 using the building repair / dismantling apparatus A and repair the curtain wall 15.

  Further, when the curtain wall 15 is repaired using the building repair / dismantling apparatus A, a new curtain wall 15 having an energy saving function may be installed, or at the same time as the repair of the curtain wall 15, It is possible to repair the equipment. For this reason, it is possible to make the building T earthquake-proof and energy-saving by using the building repair / dismantling apparatus A simultaneously with the repair of the curtain wall 15. This makes it possible to greatly contribute to global environmental conservation.

  Further, in the building renovation / dismantling apparatus A and the building renovation / dismantling method of the present embodiment, the outer body 1 is formed in an annular shape so as to surround the building T. The body 1 (building repair / dismantling apparatus A) is less susceptible to wind pressure and the like, and can be installed on a predetermined floor of the building T in a stable state.

  Further, for example, when removing the curtain wall 15 and asbestos on each floor from the upper floor to the lower floor while suspending the outer body 1 (building repair / dismantling apparatus A) from the upper floor to the lower floor with the crane 10, for example. The curtain wall 15 on the floor above the predetermined floor where the curtain wall 15 to be removed is already removed, and the hollow rubber 4 advanced from the end 1d of the roof portion 1b is moved to the outer peripheral portion T1 (curtain wall 15 on the upper floor). There is a possibility that the gap cannot be closed by closely adhering to. On the other hand, in this embodiment, since the upper floor isolation hood 6 is provided, by rotating the front end side of the opening / closing plate portion 6a so as to be in close contact with the upper floor slab 23 (outer peripheral portion T1), for example. The upper floor isolation hood 6 can reliably separate the inside and the outside of the outer body 1 and make them discontinuous. Thereby, it can prevent reliably that asbestos is scattered outside through the clearance gap between the edge part 1d of the roof part 1b, and the outer peripheral part T1 of the building T. FIG.

  As mentioned above, although one embodiment of the building renovation / demolition apparatus and the building renovation / demolition method according to the present invention has been described, the present invention is not limited to the above-described embodiment, and does not depart from the spirit of the present invention. It can be changed as appropriate. For example, in the present embodiment, the outer body 1 of the building repair / dismantling apparatus A is formed in an annular shape so as to surround the outer peripheral portion T1 of the building T (so as to surround the four circumferences of the building T). The outer shell 1 (building repair / dismantling apparatus A) may be formed so as to cover a part of the outer peripheral portion T1 of the building T. In this case, the building is kept in a stable state so that it is not affected by wind pressure, etc. by temporarily supporting it at the corners of the building T or by obtaining support from the gondola rail of the building T. It is possible to install the repair / dismantling apparatus A.

  In this embodiment, the curtain wall and asbestos are sequentially removed from the upper floor to the lower floor, and the renovation is performed. However, of course, the building repair / dismantling apparatus and the building according to the present invention are described. The repair / dismantling method may be applied to local repair of the building T.

  Further, in the present embodiment, the description has been made so that the asbestos is removed inside the outer body 1 (working chamber). However, for example, the curtain wall is removed and the asbestos is not scattered inside the outer body 1. The asbestos may be removed at the stage where the work yard 21 is conveyed.

  In the present embodiment, the building repair / dismantling apparatus A has been described as repairing the building T (curtain wall 15 repair). However, the building repair / dismantling apparatus A according to the present invention is described below. It may be used when the building T is dismantled. That is, when the frame of the building T is sequentially demolished from the upper floor to the lower floor, the curtain wall 15 and asbestos from the upper floor to the lower floor are sequentially removed using the building repair / dismantling apparatus A according to the present invention. You may make it go. Even in this case, as in the present embodiment, it is possible to reliably prevent the asbestos from being scattered to the outside and perform the dismantling work of the building T. At this time, for example, the roof portion 1b of the outer body 1 is formed so as to cover the uppermost portion T2 of the building T, and a guide rail for transportation such as H-shaped steel is attached to the roof portion 1b, so The internal dismantling material that has been dismantled may be transported to the building repair / dismantling apparatus A and carried out to the ground G by the lifting machine 16. And when the roof part 1b of the outer shell 1 is formed so as to cover the uppermost part T2 of the building T in this way, it becomes possible to perform the dismantling work without being influenced by the weather, and the all-weather dismantling It can also be applied as a construction method.

  Further, in the present embodiment, the elastic members according to the present invention are hollow rubbers 4 and 5, and the hydraulic cylinders 2 and 3 are movable forward and backward from the end portions 1d and 1e of the roof portion 1b and the floor portion 1c toward the outer peripheral portion T1. It was assumed that it was provided. On the other hand, for example, compressed air is supplied to the elastic members (hollow rubbers 4 and 5) and bulged (expanded) toward the outer peripheral portion T1, so that the end portions 1d and 1e of the roof portion 1b and the floor portion 1c and the outer periphery are expanded. It may be configured to close the gap between the portions T1, and the mechanism for moving the elastic member according to the present invention and the type of the elastic member are not necessarily limited to those shown in the present embodiment.
