Regarding the material unloading system.

Patent Documents 1 to 4 are known as techniques for transferring a demolition material from an upper floor to a lower floor of a building when the building is dismantled. The "building rebuilding method" of Patent Document 1 is a method of rebuilding a building having an underground structure, in which the old building is dismantled and the underground structure of the old building is filled with a filler to build a new building. It is formed on the support ground for the building, and the bottom plate structure part and the underground structure part of the new building are formed on the support ground, and the demolition gala generated in the upper part of the old building opened in the floor slab. It is dropped into the underground structure through the vertical hole.

In the "building demolition method" of Patent Document 2, a freight lift that can be raised and lowered along the outer peripheral surface of a high-rise building is constructed, and demolition heavy machinery and the like are lifted on the roof by the freight lift. In addition, scaffolding for curing will be installed on the outer peripheral surface of high-rise buildings. Then, the dismantling work is sequentially performed from the rooftop floor to the lower floors using heavy machinery such as a crusher and a crawler dump truck. To carry out the demolition material, the crawler dump truck loaded with the demolition material is lowered to the first floor by the freight lift, the demolition material is dropped to the collection place, and the empty crawler dump truck is used to the demolition lift. I try to lift it up to.

In the "method for dismantling a skyscraper" of Patent Document 3, a dismantling machine is placed on the floor to be dismantled of the skyscraper, the floor of the floor to be dismantled is partially demolished to provide an opening, and a roll crusher is used to be the floor to be dismantled. A preparatory step of arranging the roll crusher on the floor directly below the floor to position the loading port of the roll crusher near the opening, and cutting and disassembling the floor to be dismantled by the dismantling machine, and charging the generated waste material into the loading port. Then, the waste material crushed by the roll crusher is sorted into concrete and reinforcing bars, and the dismantling process of dropping them separately and carrying them out is repeated in sequence to dismantle to the lower floors of the skyscraper. However, it is made to fall through the rudder provided on the elevator shaft.

In moving the dismantling material from the upper floor to the lower floor, Patent Document 1 drops the dismantling material through a vertical hole portion opened in the floor slab. Since this technology does not have a sound insulation structure, there has been a problem of noise and vibration generated when the dropped demolition material collides with the floor or wall of the lower floor or the demolition material dropped earlier. In addition, since the dismantling material is not provided with a curing structure at the drop position, there is a problem in ensuring safety against debris of the dismantling material that collides with the floor or the like and shatters.

In Patent Document 2, a freight lift is constructed for use in carrying out dismantled materials. The freight lift is a large-scale facility, and there is a problem that the facility cost increases. Further, in order to move the dismantled material to the lower floors, it is necessary to move the crawler dump truck back and forth with a cargo lift, and it takes time and effort to carry out the dismantled material, which is inefficient.

In Patent Document 3, the rudder in the elevator shaft is used to drop the dismantled material at a slow speed while absorbing shock. Although the loudness of noise is reduced in this technique, there is a problem that the generation time of sound is prolonged. In addition, since it is equipped with a ladder, there is a problem that it takes time and effort to install the equipment.

In Patent Document 4, a vertical cylinder with a valve is provided exclusively for carrying out the dismantled material. Similar to Patent Document 2, the tubular body with a valve of this technology is a large-scale facility, and has a problem that the facility cost increases. In addition, the dismantling material dropped into the cylinder may cause blockage in the cylinder, and there is a concern that the dismantling material may be hindered from being carried out.

The present invention has been devised in view of the above-mentioned conventional problems, and is capable of smoothly and surely carrying out the dismantled material, reducing noise and vibration, ensuring safety of the dismantled material, and having a structure. An object of the present invention is to provide a building demolition material unloading system that can be easily constructed at low cost.

As shown in FIG. 1, the building demolition material carry-out system according to the present embodiment is dismantled when a middle-high-rise building, for example, an existing RC building 1 having a height of about 60 m is dismantled from the top floor to the lower floor. It is used to move the demolition material W from the demolition work construction floor FZ where the work is being carried out to the carry-out floor FA, for example, the ground floor.

The demolition work construction floor FZ shifts from the top floor to the floor directly below it and then to the floor directly below it as the demolition of the building 1 progresses. Around the building 1, a protective wall 2 for dustproofing and soundproofing is temporarily installed so as to surround the entire building 1 at a height reaching the top floor from the ground G.

In the building 1 to be demolished, in order to drop the demolition material W, from the demolition work construction floor FZ on the top floor to be demolished first, to the floor directly above the carry-out floor FA of the demolition material W, for example, the floor directly above the ground floor. Openings 4b, 4c, ..., 4x, 4z are formed through the floor slabs 3b, 3c, ..., 3x, 3z of each floor FB, FC, ..., FX. These openings 4b, 4c, ..., 4x, 4z are formed by a heavy dismantling machine 5 such as a crusher that is carried into each floor by using a crane, a temporary lift, or the like.

These openings 4b, 4c, ..., 4x, 4z are formed at the same position with respect to the building plane and having substantially the same diameter so as to communicate with each other in a series in the height direction of the building 1. In the illustrated example, as shown in FIG. 2 and the like, it is formed in a quadrangular shape, but it may be formed in a circular shape or another polygonal shape.

The positions of the openings 4b, 4c, ..., 4x, 4z of each floor FB, FC, ..., FX, FZ on the building plane may be freely set. For example, when there is a dwelling around the building 1 to be demolished, by providing openings 4b, 4c, ..., 4x, 4z at a position as far as possible from the neighboring dwelling, specifically, the building 1 is surrounded by the dwelling. In this case, by providing openings 4b, 4c, ..., 4x, 4z at the center of the building 1, the influence of noise and vibration on neighboring houses can be reduced.

On the dismantling work construction floor FZ, the dismantling heavy machine 5 moves on the floor slab 3z, and the dismantling work is advanced, whereby the dismantling material W is generated. At this time, the dismantling material W may be sorted into a concrete block and a reinforcing bar or the like. Further, in order to support the floor slab 3z of the demolition work construction floor FZ to which the demolition heavy machine 5 moves, a plurality of reinforcing posts 6 are arranged over one layer directly below the demolition work floor FZ and two layers below it. You may set it up.

The demolition material W generated on the demolition work construction floor FZ is dropped toward the lower side of the building 1 through the opening 4z of the floor slab 3z of the demolition work construction floor FZ. The dropped demolition material W falls through the floor slabs 3b, 3c, ..., 3x openings 4b, 4c, ..., 4x that communicate with each other in a series, and reaches the carry-out floor FA. The carry-out floor FA faces the lower storage chamber LS inside the lower enclosure 7 to be described later, and cushions the impact of the dismantling material W dropped on the carry-out floor FA to suppress the generation of noise and vibration. The shock absorber 8 is provided.

The cushioning portion 8 penetrates the floor slab 3a of the carry-out floor FA at the same building plane position as the openings 4b, 4c, ..., 4x, 4z on each floor, and opens downward at an appropriate depth. 4b, 4c, ..., 4x, 4z Cushioning material filling pit 8a formed with approximately the same diameter and the dismantling material that is filled in the cushioning material filling pit 8a and reaches the carry-out floor FA. It is composed of a cushioning material 8b that acts as a cushion to receive W and cushions noise, shock vibration, and the like. As the cushioning material 8b, waste materials such as interior materials of the building 1 are used.

The cushioning material 8b is filled in the cushioning material filling pit 8a to a height substantially matching the upper surface level of the floor slab 3a of the carry-out floor FA so as not to interfere with the carry-out of the dismantled material W in the carry-out floor FA. The cushioning portion 8 does not need to form the cushioning material filling pit 8a, and may simply spread the cushioning material 8b on the floor slab 3a of the carry-out floor FA.

As shown in FIGS. 1 to 4, the carry-out floor FA is a lower-layer enclosure that internally forms a lower-layer storage chamber LS capable of storing the dismantled material W at a height reaching the floor height of the carry-out floor FA. 7 is provided. The lower enclosure 7 is formed at a height reaching from above the floor slab 3a of the carry-out floor FA to below the floor slab 3b on the floor immediately above it (the standby floor FB described later).

The lower layer enclosure 7 is provided so as to surround the opening 4b of the waiting floor FB. In the illustrated example, the lower layer enclosure 7 is formed in a planar quadrangular shape in accordance with the planar shape of the opening 4b of the standby floor FB. The shape may be different from the planar shape of the opening 4b.

In the lower layer enclosure 7, steel frame units 7a assembled in a flat square shape are arranged in multiple stages at appropriate intervals in the height direction, and steel is formed on four surfaces partitioned inside the frame units 7a. H-shaped steel columns 7c, which are assembled in a square cylinder by disposing the wall material 7b and are arranged so as to face each other on any pair of opposite sides of the frame unit 7a at their end positions. By fixing to the floor slab 3a of the carry-out floor FA with an anchor, the steel is fixed to the carry-out floor FA and installed, and the space inside the floor is the lower storage room LS.

As a result, the dismantling material W can be stored in the lower storage room LS at a height reaching the floor height of the carry-out floor FA from the upper surface of the floor slab 3a of the carry-out floor FA through the opening 4b of the standby floor FB. Will be done. The lower enclosure 7 is designed so that it will not be damaged even if the heavy equipment 11 for unloading, which will be described later, is accidentally touched when performing heavy equipment work, and also to reduce the anxiety of the worker who works on the FA on the unloading floor. , Formed from steel lumber.

Further, in the lower storage chamber LS, with respect to the dismantled material W that starts to be dropped from the empty state, the impact due to the dropping is buffered by the buffer portion 8, and noise and vibration are suppressed. After the dismantling material W has been dropped to the extent that it covers the buffer portion 8, the impact due to the dropping is buffered by the dismantling material W dropped earlier, and noise and impact are suppressed. The noise is also reduced by the lower enclosure 7 itself.

The lower enclosure 7 provided on the carry-out floor FA is formed with a discharge port 9 for opening the lower storage chamber LS into the space of the carry-out floor FA at an appropriate place in the circumferential direction, and the discharge port 9 is closed. A door means 10 that can be opened and closed to hold the dismantling material W in the lower layer storage chamber LS inside the lower layer enclosure 7 or open the discharge port 9 so that the dismantling material W can collapse to the outside of the lower layer enclosure 7. Provided. The discharge ports 9 may be provided at appropriate positions in the circumferential direction of the lower layer enclosure 7, and the number of the discharge ports 9 may be one or a plurality.

In the present embodiment, the wall material 7b provided on any one of the four surfaces partitioned inward by the frame unit 7a constituting the lower enclosure 7 is under the floor slab 3b of the waiting floor FB. It is vertically installed with a slight height dimension (see FIG. 1), whereby a single discharge port 9 is formed below the wall material 7b over the upper surface of the floor slab 3a of the carry-out floor FA.

The wall material 7b provided on the remaining three surfaces of the lower enclosure 7 is formed with a height dimension between the floor slabs 3a and 3b of the carry-out floor FA and the standby floor FB, thereby excluding the discharge port 9. The lower storage room LS has a structure partitioned from the carry-out floor FA.

As shown in FIGS. 3 and 4, the door means 10 has a large number of insertion / extraction holes (not shown) individually formed in a large number of columns 7c on both sides at the discharge port 9 along their height directions. The discharge port 9 is closed in order to hold the dismantling material W inside the lower layer enclosure 7 by inserting the dismantling material W into the lower layer enclosure 7 by inserting it into the insertion / removal hole and hanging it between the columns 7c. It is composed of a plurality of rods 10a in which the discharge port 9 is opened in order to allow the dismantling material W to collapse to the outside of the lower enclosure 7 by being pulled out from the insertion / extraction hole and removed from between the columns 7c. To.

The lower layer enclosure 7 including the door means 10 has a wall material 7b and a column so as to narrow the depth from the discharge port 9 and the lateral spread in order to facilitate the removal of the dismantling material W from the discharge port 9. 7c is placed close to the rim of the opening 4b of the waiting floor FB.

Heavy equipment 11 for carrying out such as backhoes and excavators is carried into the carry-out floor FA, and the dismantling material collapses from the lower layer storage chamber LS to the outside of the lower layer enclosure 7 through the discharge port 9 opened by the door means 10. W is unloaded by the unloading heavy machine 11.

An upper layer enclosure 17 is provided in the upper layer FC above the carry-out floor FA. The upper level FC above the carry-out floor FA is a level including at least the floor directly above the carry-out floor FA, and may be one level or two or more levels. In the present embodiment, a case where the floor directly above the carry-out floor FA is set as the standby floor FB is shown between the carry-out floor FA and the upper level FC. Without setting the standby floor FB, the floor directly above the carry-out floor FA may be used as the upper floor FC. Further, in the illustrated example, only the floor directly above the standby floor FB is set as the upper floor FC.

On the floor directly above the carry-out floor FA, that is, on the waiting floor FB that waits for the dismantling material W to collapse to the carry-out floor FA, as shown in FIGS. 1 and 5, the height reaches the height of the waiting floor FB inside. A middle layer enclosure 12 for partitioning the middle layer storage chamber MS capable of collapsingly storing the dismantled material W in the lower storage chamber LS is provided. The middle layer enclosure 12 is formed at a height extending from above the floor slab 3b of the waiting floor FB to below the floor slab 3c of the floor immediately above it (the lowest floor of the upper floor FC described later).

The middle layer enclosure 12 is provided so as to surround the waiting floor FB and the openings 4b and 4c on the floor immediately above the standby floor FB. In the illustrated example, the middle layer enclosure 12 is formed in a planar quadrangular shape in accordance with the planar shape of the standby floor FB and the openings 4b and 4c on the immediately above floor. The shape may be different from the planar shape of these openings 4b and 4c.

In the middle-layer enclosure 12, the single-tube units 12a assembled in a flat square shape are arranged in multiple stages at appropriate intervals in the height direction, and the single-tube units 12a stand by on four surfaces partitioned inward. A plywood wall material 12b having a height dimension between the floor slabs 3b and 3c on the floor FB and the floor directly above is arranged and assembled in a square tube shape, and fixed to the floor slab 3b on the standby floor FB. , The space inside it is called the middle-rise storage room MS.

As a result, the dismantling material W is stored in the middle floor storage room MS at a height reaching the floor height of the waiting floor FB from the floor slab 3b of the waiting floor FB through the opening 4c of the immediately above floor (upper floor FC). Is possible.

As shown in FIG. 5, the middle layer enclosure 12 is installed so that the positions above the door means 10 and the other positions are different from each other with respect to the openings 4b and 4c. Specifically, the enclosure points P directly above the door located above the door means 10 are arranged close to the rims of the openings 4b and 4c, and are arranged except for the enclosure P directly above the door (enclosure directly above the non-door). The points Q) are arranged apart from the rims of the openings 4b and 4c so as to be separated from each other.

When the dismantling material W is stacked and stored, a part of the downward load generated by the stacking acts in the lateral direction. For example, the wall material 12b of the middle layer enclosure 12 and the opening 4b opening of the floor slab 3b of the standby floor FB The dismantling material W in contact with the periphery of the edge is firmly brought into close contact with the wall material 12b, the mouth edge of the opening 4b, or the like, which may cause blockage.

Since the lower layer enclosure 7 is provided with the discharge port 9 opened by the door means 10, if the discharge port 9 is opened by the door means 10, the dismantling material W in the lower layer storage chamber LS will naturally be released. Alternatively, it easily collapses, and the dismantling material W is rarely blocked in the lower storage chamber LS.

On the other hand, in the middle layer enclosure 12, especially in the enclosure P directly above the door above the door means 10, the discharge port 9 is opened by the door means 10 in a state where some adhesion is applied to the enclosure P, and the dismantling material is used. When W collapses to the outside of the lower storage chamber LS and a slack such as a vacancy occurs directly above the door and immediately below the enclosure P, as shown in FIG. 7, the adhesion force doubles and acts to dismantle the material. W will come into close contact and blockage will occur.

At this time, if the floor slab 3b of the waiting floor FB is squeezed into the dismantling material W at the enclosure P directly above the door, the blockage may be further promoted.

Therefore, in the present embodiment, in order to suppress the occurrence of blockage due to the dismantled material W that is stacked and stored, at least the floor slab 3b of the waiting floor FB should not be "protruded" with respect to the dismantled material W. In addition, at the enclosure P directly above the door, the middle layer enclosure 12 is positioned close to the rim of the opening 4b of the waiting floor FB.

On the other hand, the above-mentioned "slack" due to the collapse of the dismantling material W, which causes blockage in the enclosure Q itself directly above the non-door, should hardly occur, and a large amount of the dismantling material W stored in the middle layer storage room MS should be secured. Also, to improve the safety of the installation work by securing the installation work space of the middle layer enclosure 12 on the opening 4b, 4c side, which cannot be obtained at the rim of the openings 4b, 4c, it was dropped. From the viewpoint of suppressing the generation of noise and vibration caused by the dismantling material W directly colliding with the middle layer enclosure 12, the enclosure Q directly above the non-door is separated from the rims of the openings 4b and 4c. Positioned.

In the middle-layer storage room MS, the impact caused by dropping the dismantling material W is buffered by the dismantling material W dropped earlier, and noise, impact, and vibration are suppressed. The noise is also reduced by the middle layer enclosure 12 itself.

As described above, the upper layer enclosure 17 is provided in the upper layer FC above the standby floor FB. As shown in FIGS. 1 and 6, the dismantling material W is placed inside the upper layer enclosure 17 via the middle layer storage chamber MS up to the set storage height H (see FIG. 9) described later during the dismantling work. The upper storage chamber HS is partitioned so that it can be collapsed and stored in the lower storage chamber LS. The upper enclosure 17 is formed at a height extending from above the floor slab 3c of the floor FC on which it is installed to below the floor slab 3d on the floor immediately above it.

The upper layer enclosure 17 is provided so as to surround an opening on each floor, for example, the opening 4c in the upper layer FC. In the illustrated example, the upper layer enclosure 17 is formed in a planar quadrangular shape according to the planar shape of the openings (for example, the openings 4c) formed on each floor of the upper layer FC. The shape may be different from the planar shape of the opening.

Similar to the middle-layer enclosure 12, the upper-layer enclosure 17 has single-tube units 17a assembled in a plane quadrangular shape arranged in multiple stages at appropriate intervals in the height direction, and inside these single-tube units 17a. Plywood wall material 17b having the height dimension between the floor slabs of each floor in the upper floor FC (for example, the dimension between the floor FC directly above the standby floor FB and the floor slabs 3c and 3d on the floor immediately above it) on the four partitioned surfaces. Are arranged and assembled in a square tube shape, and fixedly installed on each floor, and the space inside the space is referred to as an upper storage room HS.

As a result, the demolition material W dropped from the demolition work construction floor FZ can be stored in the upper storage chamber HS so as to be collapsible toward the lower storage chamber LS.

In the upper layer enclosure 17, the amount of the dismantling material W piled up at the height position is small, the dismantling material W causing blockage hardly generates a large lateral pressure, and the dismantling material W is stored in the upper storage chamber HS. To secure a large amount, and to secure the installation construction space of the upper layer enclosure 17 on the opening 4c side to improve the safety of the installation construction, the dismantling material W to be dropped is directly applied to the upper layer enclosure 17. From the viewpoint of suppressing the generation of noise and vibration due to collision, as shown in FIG. 6, the openings 4c and 4d of the floor slabs 3c and 3d on each floor are surrounded by the openings 4c and 4d. It is installed at a distance from the edge. The noise is also reduced by the upper enclosure 17 itself.

As shown in FIGS. 1 and 8, the dismantling material W is used to block the floor slab 3b of the standby floor FB, which is above the door means 10 which is likely to cause blockage as described above, and directly above the door means 10 in the present embodiment. A hydraulic cylinder unit 18 and a jack are installed as a force device for applying a force to the stored dismantling material W in order to release the force.

The hydraulic cylinder unit 18 includes a piston rod 18a that is penetrated through a through hole (not shown) through a through hole (not shown) in the enclosure portion P directly above the door of the intermediate layer enclosure 12 and is advanced / retracted in the intermediate layer storage tank MS. By advancing and retreating 18a, a force is applied to the dismantling material W stored directly above and around the door means 10 in the middle layer storage chamber MS, whereby the blockage can be released.

The hydraulic cylinder unit 18 is a piston rod that is installed under the floor slab 3b of the standby floor FB and penetrates the lower layer enclosure 7 if it is above the door means 10, and the dismantling material W stored in the upper end portion thereof. You may try to apply force to. The number of hydraulic cylinder units 18 installed is not limited to one, and may be a plurality of units. In this case, a plurality of through holes are provided in the enclosure portion P directly above the door, and a plurality of piston rods 18a are provided in each of the through holes. Is installed through the piston freely.

A flexible metal hanging member, such as a steel chain 19, is further provided for releasing the blockage by the dismantling material W. As shown in FIG. 1, the chain 19 has a start end portion 19a pulled out upward of the upper layer enclosure 17 and an end portion 19b pulled out of the lower layer enclosure 7 to the inside of the upper layer enclosure 17 and the lower layer enclosure 7. It is provided so as to hang downward from the upper storage chamber HS to the lower storage chamber LS so as to pass between the stored dismantling materials W. Since the chain 19 is arranged before the dismantling material W is dropped, when the dismantling material W is dropped, the chain 19 naturally passes between them.

As shown in FIG. 8, the end portion 19b side of the chain 19 is arranged lying on the floor slab 3a of the carry-out floor FA, and the chain 19 is formed in the groove or the lower layer enclosure 7 formed in the floor slab 3a. It is provided from the outside of the lower layer enclosure 7 toward the lower layer storage chamber LS inside the lower layer enclosure 7 through a through hole. A plurality of chains 19 are arranged inward of the rim of the openings 4b, 4c, 4d of the floor slabs 3b, 3c, 3d at intervals along the circumferential direction of the openings 4b, 4c, 4d.

In the present embodiment, three of the sides of the square openings 4b, 4c, and 4d are arranged so as to be located on three sides except the side corresponding to the installation position of the discharge port 9. The number of chains 19 is not limited to three, and an appropriate number may be installed. Further, regarding the installation position of the discharge port 9, the chain may be added by pulling out the terminal portion to the outside of the middle layer enclosure 12 of the standby floor FB.

Each chain 19 is pulled up from the upper layer FC side to move the stored dismantling material W, thereby releasing the blockage due to the close contact of the dismantling material W. The operation of pulling up the chain 19 may be performed by winding it around a chain block (not shown).

By pulling up the chain 19 from the start end portion 19a side, the end portion 19b side gradually approaches the lower layer enclosure 7, but the end portion 19b is pulled up so as not to be pulled inward of the lower layer enclosure 7. An additional chain 20 is connected and provided to the terminal portion 19b in order according to the amount of operation (see FIG. 9). Wires may be used instead of the chains 19 and 20.

Further, in the building demolition material carry-out system according to the present embodiment, when the demolition material W is carried out, the demolition material W is carried out at the carry-out floor FA, specifically, the demolition material W is stored to a predetermined height. As a result, in order to reduce the step from the demolition work construction floor FZ to the top of the demolition material W stored and to make the stored demolition material W play a role as a buffer material, the lower layer storage chamber LS to the upper layer. A set storage height H that defines the storage amount of the dismantled material W over the storage chamber HS is set. The set storage height H is set as the storage height in the upper storage chamber HS.

A distance meter 21 and a load sensor 22 are provided as measuring means for measuring the set storage height H. The distance meter 21 is provided on the dismantling work construction floor FZ in order to measure the distance to the top of the dismantled material W that has been stacked and stored. Of course, the distance meter 21 may be provided on a floor other than the dismantling work construction floor FZ as long as it is at a position higher than the set storage height H.

When the dismantled material W is carried out from the lower storage chamber LS via the discharge port 9, the change in the distance to the top is measured by the range finder 21. In the dismantling work, the dismantling material W is dropped from the dismantling work construction floor FZ so that the top position of the dismantling material W measured by the distance meter 21 is returned to the set storage height H.

The load sensor 22 measures the lateral pressure generated in the enclosures 7, 12, and 17 by the stored dismantling material W, and the corresponding lateral pressure generated when the dismantled material W is stored up to the set storage height H, that is, the corresponding. Is set as the set load, and the load sensor 22 detects whether or not the load being measured reaches the set load. Also in the case of the load sensor 22, in the dismantling work, the dismantling material W is dropped so that the measured lateral pressure (load) is maintained at the set load.

The load sensor 22 is provided in at least one of the lower layer enclosure 7, the middle layer enclosure 12, and the upper layer enclosure 17. Of course, it may be provided in all the enclosures 7, 12, and 17. From the viewpoint of measuring whether or not the top end position of the dismantling material W is the set storage height H, it is preferable to provide it on the wall material 17b of the upper layer enclosure 17.

The demolition work construction floor FZ will gradually move to the lower floors. The set storage height H may be a constant set height H until it shifts to the upper layer FC in which the upper layer storage chamber HS is partitioned by the upper layer enclosure 17, but it is necessary instead. Correspondingly, as the dismantling work construction floor FZ moves to the lower floor, the height may be reset to a lower level.

Then, when the demolition work construction floor FZ shifts to the upper floor FC and the dismantling of the floor is started, the setting of the set storage height H is canceled, and the dismantling material W is simply carried out from the discharge port 9. The dismantling material W may be dropped according to the amount dropped.

Next, the implementation status of the demolition material unloading by the building demolition material unloading system according to the present embodiment will be described with reference to FIG. The demolition heavy machine 5 is made to stand by on the top floor (demolition work construction floor FZ) of the building 1 to be demolished, and the carry-out heavy machine 11 is made to stand by on the carry-out floor FA. Then, first, the dismantling heavy machine 5 starts dismantling the dismantling work construction floor FZ. Before the dismantling material W is dropped from the dismantling work construction floor FZ, the discharge port 9 of the carry-out floor FA is closed by the door means 10 in which all the rods 10a are inserted into the insertion / extraction holes.

With the discharge port 9 closed by the door means 10, the dismantling material W is dropped from the dismantling work construction floor FZ. The dropped dismantling material W reaches the lower storage chamber LS inside the lower enclosure 7 and falls onto the buffer portion 8. When the shock absorber 8 is almost covered with the dismantling material W, the falling dismantling material W falls on the dismantling material W previously dropped into the lower storage chamber LS and is piled up on it. To go.

The state in which the discharge port 9 is closed by the door means 10 is maintained, the dropping of the dismantling material W from the dismantling work construction floor FZ is continued up to the set storage height H, and the dropped dismantling material W is the lower storage chamber LS. It is stacked and stored from the middle layer storage room MS to the upper layer storage room HS. Whether or not the top end of the dropped demolition material W has reached the set storage height is measured by the distance meter 21, the load sensor 22, or both.

As described above, the set storage height H reduces the step from the demolition work construction floor FZ to the top of the demolition material W stored, and causes the stored demolition material W to play a role as a cushioning material. Set for. For example, when the dismantling material W is charged from a height of 60 m, it is necessary to increase the storage height to 6 m or more in order to reduce the vibration at a place 10 m away to 55 decibels or less. Since this height changes depending on the size of the demolition material W, the ground condition, etc., it is desirable to conduct an experiment before the demolition work to set the set storage height H.

When the dropping of the dismantling material W up to the set storage height H is completed with the discharge port 9 closed by the door means 10, then the discharge port 9 is opened by the door means 10. After the door means 10 is opened, the work of carrying out the dismantling material W on the carry-out floor FA and the work of dropping the dismantling material W on the dismantling work construction floor FZ are repeated in parallel. This repetitive work is performed at least until the start of the dismantling work of the floor provided with the upper storage room HS, that is, the floor immediately above the upper floor FC.

By the unloading work, the dismantling material W that collapses from the lower storage chamber LS to the outside of the lower enclosure 7 by opening the door means 10 is unloaded from the unloading floor FA. The collapse of the dismantling material W is restricted by the angle of repose, and the dismantling material W that collapses from the discharge port 9 is safely carried out by the unloading heavy machine 11. When the dismantling material W is carried out, the top position of the stored dismantling material W is lowered.

In the dropping work, the distance meter 21 and the load sensor 22 continue to measure the top position of the dismantling material W, and the top end of the dismantling material W that is lowered by carrying out the dismantling material W is returned to the set storage height H and maintained. As described above, the dismantling material W is dropped from the dismantling work construction floor FZ.

When the dismantling material W is blocked and the dismantling material W does not move to the lower storage chamber LS, the blockage release operation is performed. One of the blockage releasing operations reciprocates the piston rod 18a of the hydraulic cylinder unit 18. As a result, at the height position of the waiting floor FB, the dismantling material W of the enclosure P directly above the door is stimulated to move, and the blockage is released. In the other blockage releasing operation, any or all of the chains 19 provided in the circumferential direction of the openings 4b, 4c, and 4d are pulled up.

As a result, between the lower storage chamber LS and the upper storage chamber HS, the stored dismantling material W is stimulated to move, and the blockage is released. When the blockage is released, the dismantling material W collapses toward the lower storage chamber LS and collapses from the discharge port 9, so that the dismantling material W is carried out by the heavy equipment 11 for carrying out. For the chain 19 to be pulled up, an additional chain 20 is connected at the carry-out floor FA for replenishment.

Every time the dismantling work construction floor FZ moves to the lower floor, the dismantling heavy equipment 5 and the reinforcing post 6 are replaced to the lower floor accordingly. When the upper layer FC in which the upper layer storage chamber HS is formed in the upper layer enclosure 17 becomes the dismantling work construction floor FZ, the upper layer enclosure 17 is removed. The starting end portion 19a of the chain 19 is pulled out above the middle layer storage chamber MS.

When the set storage height H is set in the height range of the upper storage room HS, the set storage height H is reset to the height range of the middle layer storage room MS of the standby floor FB. Since the height position of the standby floor FB is extremely lower than the height position of the top floor of the building before the demolition work, the demolition material W in the middle-rise storage room MS does not have to reset the set storage height H. The unloading operation and the dropping operation may be repeated so that the storage is maintained.

That is, if the storage of the dismantling material W extends from the lower layer storage chamber LS to the middle layer storage chamber MS, noise and vibration are suppressed by dropping the dismantling material W on the dismantling material W, and collapse from the discharge port 9. Safe transportation of the dismantling material W using the delivery is continuously ensured.

When the waiting floor FB on which the middle layer storage chamber MS is formed in the middle layer enclosure 12 becomes the dismantling work construction floor FZ, the middle layer enclosure 12 is removed. The starting end portion 19a of the chain 19 is pulled out above the lower storage chamber FA. At this height, the setting of the set storage height H is canceled. Then, the dismantling material W of the waiting floor FB is dropped into the lower storage room LS and carried out from the discharge port 9.

Finally, when the carry-out floor FA becomes the dismantling work construction floor FZ, the lower enclosure 7 is removed, the floor slab 3b of the standby floor FB, the pillars of the carry-out floor FA, etc. are dismantled, and the dismantling material W is used. It is carried out from the carry-out floor FA.

In the building demolition material carry-out system according to the present embodiment described above, each floor FB, FC, ..., FX floor slab 3b extending from the demolition work construction floor FZ to the floor directly above the demolition material W carry-out floor FA. , 3c, ..., 3x, 3z are formed with openings 4b, 4c, ..., 4x, 4z having substantially the same diameter that communicate with each other, and through these openings 4b, 4c, ..., 4x, 4z. This is a building demolition material unloading system in which the demolition material W is dropped from the demolition work construction floor FZ to the unloading floor FA, and the demolition material W is unloaded from the unloading floor FA. A lower storage chamber LS capable of storing the dismantling material W is formed at a height reaching the floor height of the carry-out floor FA, and the dismantling material W in the lower storage chamber LS can be collapsed to the outside at appropriate locations. An upper layer that is provided in the lower enclosure 7 on which the discharge port 9 is formed and the upper layer FC above the carry-out floor FA including at least the floor directly above the carry-out floor FA, and can store the demolition material W in the lower storage room FA so as to be collapseable. It is provided with an upper layer enclosure 17 for partitioning the storage chamber HS, and further, the start end portion 19a is pulled out above the upper layer enclosure 17 and the end portion 19b is pulled out to the outside of the lower layer enclosure 7, and the stored dismantling is performed. It is provided so as to hang downward from the upper storage chamber HS inside the upper enclosure 17 and the lower enclosure 7 so as to pass between the materials W toward the lower storage chamber LS, and is pulled up to move the dismantling material W. A chain 19 is provided to release the blockage by the demolition material W, and a simple structure and a low-cost unloading system can be constructed by the simple enclosures 7, 17 and the chain 19, and also the enclosure. In addition to being able to reduce noise and vibration and ensure safety against the dismantling material W by the 7 and 17 themselves, even if the dismantling material W causes blockage in the enclosures 7 and 17, the chain With an extremely simple device configuration of 19 arrangements, smooth and reliable unloading work of the dismantling material W can be ensured.

Since a plurality of chains 19 are provided at intervals in the circumferential direction of the openings 4b, 4c, 4d, the blockage can be appropriately performed regardless of the location of the cause of the blockage in the circumferential direction of the enclosures 7 and 17. It can be released.

The chain 19 is provided with an additional chain 20 connected to the terminal portion 19b in order according to the pulling operation amount so that the terminal portion 19b is not pulled inward of the lower layer enclosure 7, so that the blockage is released. The work to be done can be carried out appropriately without any trouble.

The lower layer enclosure 7 including the door means 10 narrows the depth from the discharge port 9 and the lateral spread in order to facilitate the removal of the dismantling material W from the discharge port 9, and opens the standby floor FB. In the middle layer enclosure 12, at least the floor slab 3b of the standby floor FB is set to the demolition material W in order to suppress the occurrence of blockage due to the demolition material W that is stacked and stored. On the other hand, in the enclosure directly above the door P, the middle-layer enclosure 12 is positioned close to the rim of the opening 4b of the waiting floor FB so as not to be “protruding”, while the non-door directly above the enclosure Q itself is closed. There is almost no occurrence of the above-mentioned "slack" due to the collapse of the dismantling material W, which causes the above, secure a large amount of the dismantling material W stored in the middle layer storage chamber MS, and also, the rims of the openings 4b and 4c. To improve the safety of installation work by securing the installation work space of the middle layer enclosure 12 which cannot be obtained at all, on the openings 4b and 4c side, and the dropped demolition material W directly collides with the middle layer enclosure 12. From the viewpoint of suppressing the generation of noise and vibration due to the above, the non-door direct upper enclosure Q is positioned away from the rims of the openings 4b and 4c, and further, in the upper enclosure 17, it is The amount of demolition material W piled up at the height position is small, there is almost no generation of large lateral pressure due to the demolition material W that causes blockage, and a large amount of demolition material W is secured in the upper storage chamber HS. Further, the installation construction space of the upper layer enclosure 17 is secured on the openings 4c and 4d side to improve the safety of the installation construction, and the noise caused by the dropped demolition material W directly colliding with the upper layer enclosure 17. -From the viewpoint of suppressing the generation of vibration, the openings 4c and 4d are installed apart from the rim of the openings 4c and 4d with respect to the openings 4b, 4c and 4d of the enclosures 7, 12 and 17. By setting the width of the flat space, it is possible to ensure smooth and reliable carry-out work of the demolition material W dropped from the demolition work construction floor FZ, and the enclosure 12 in consideration of the openings 4b, 4c, 4d. , 17 can be installed safely and easily.

A hydraulic cylinder unit 18 is provided above the door means 10 to release the blockage caused by the dismantled material W by applying a force to the stored dismantling material W, so that the dismantling material W can be smoothly carried out with a simple device configuration. can do.

Since the cushioning portion 8 for cushioning the impact of the dismantling material W dropped on the carry-out floor FA is provided facing the lower storage room LS, the impact of the dismantling material W dropped on the carry-out floor FA is buffered and noise is generated. And vibration generation can be suppressed appropriately.

The door means 10 is individually and freely provided in a large number of insertion / extraction holes formed in a large number of stages along the height direction of the column 7c, and is inserted through the insertion / extraction holes to be installed inside the lower layer enclosure 7. By closing the discharge port 9 to hold the dismantling material W or pulling it out from the insertion / extraction hole and removing it, the discharge port 9 is provided so that the dismantling material W can be collapsed to the outside of the lower enclosure 7. Since it is configured with a plurality of rods 10 in an open state, it has a simple and robust structure, and it can be installed and removed by simply inserting and removing the rods 10, so it is suitable for an irregular dismantling material W. The discharge port 9 can be opened and closed by operating.

Further, when the demolition material W is carried out and the building 1 is dismantled, first, with the door means 10 closed, from the lower storage room LS to the upper storage room HS up to the set storage height H. Demolition work The demolition material W dropped from the construction floor FZ is piled up and stored, and then the door means 10 is opened to carry out the demolition material W that collapses from the lower storage room LS from the carry-out floor FA, and the set storage height. Since the dismantling work W is dropped from the construction floor FZ so that the H is maintained, the drop height of the dismantling material W is lowered by setting the set storage height H to reduce noise. By ensuring the storage of a substantially constant amount of demolition material W with low vibration at all times, it is possible to safely carry out the demolition work and the demolition work in parallel, and to carry out the demolition material smoothly, reliably and efficiently. it can.

The set storage height H is reset to a low height when the demolition work construction floor FZ moves to the lower floor, so that the drop height of the demolition material W is higher than the repeated dropping work while carrying it out. The work flow from dismantling to unloading can be facilitated so that it does not become too low, that is, the stored amount does not become excessive with respect to the unloading amount.

Since the set storage height H is measured by the distance meter 21 that measures the distance to the top of the dismantled materials W that have been stacked and stored, dismantling and carrying out are based on the measurement of the top position by a simple device configuration. Can be carried out appropriately in parallel.

The set storage height H is provided in at least one of the lower layer enclosure 7, the middle layer enclosure 12, and the upper layer enclosure 17, and the lateral pressure generated in at least one of the enclosures 7, 12, and 17 is applied. Since it is measured by the load sensor 22 to be measured, it is possible to appropriately carry out the disassembly and unloading work in parallel with a simple device configuration as in the case of the distance meter 21, and the enclosures 7, 12, It is possible to prevent excessive lateral pressure from acting on 17 and improve work safety.

FIG. 10 shows a modified example of the building demolition material carry-out system shown in FIG. In the above embodiment, the case where the plane space of the enclosures 7, 12, 17 with respect to the openings 4b, 4c, 4d is widened or narrowed has been described, but the enclosures 7, 12, 17 with respect to the openings 4b, 4c, 4d have been described. Of course, the dimensions of the building 1 may be the same in the vertical height direction, and the chain 19 may be arranged so as to hang down at the wall materials 7b, 12b, 17b of the enclosures 7, 12, and 17. is there. Even in such a modified example, the same action and effect as those of the above-described embodiment can be obtained.

In the above description, the dismantling material W has been described by exemplifying the case where it is immediately dropped from the dismantling work construction floor FZ, but it is the case where it is transferred to a floor other than the dismantling work construction floor FZ and then dropped. But the meaning is synonymous.
