Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a suspension scaffolding device used when a work scaffold is provided so as to be able to move up and down along the outer wall of a structure.

[0002]

2. Description of the Related Art In recent years, when repairing the outer wall of a building, especially a high-rise building, etc., rather than constructing a combined scaffold from the ground using steel pipes or the like to provide a working scaffold, The work scaffold will consist of suspended scaffolds that can be moved up and down along the outer wall of the building.

That is, it is possible not only to allow workers to enter, but also to arrange a suspended scaffolding main body called a gondola formed so that the worker can perform a predetermined work along the outer wall of a high-rise building. By arranging so that it can move up and down,
It is said that a working scaffold consisting of the above-mentioned suspended scaffolds will be provided.

Incidentally, the suspension scaffolding main body referred to as the gondola is suspended, for example, by a suspension wire wound around a pulley or the like provided at the upper end of the suspension scaffold, and the suspension wire is suspended on the roof of a high-rise building. The suspension scaffolding device, which is the subject of the present invention, is formed so as to be lifted and lowered by being wound up by a wire winding device that is also installed on the roof via a boom that extends from above.

On the other hand, recently, the suspension scaffolding device has a plurality of suspension scaffolding bodies connected in the lateral direction to form a continuous scaffolding, that is,
There is also a tendency to be proposed as forming a wide scaffold that is long and continuous in the lateral direction.

Then, the suspension scaffolding device of this continuous mode is
This is a mode that goes around the outer circumference of a high-rise building like a so-called headband, and the inside is a scaffolding that goes around, and this orbiting scaffolding, that is, the inside is cut off from the outside, and It has been proposed as a device that can be used as an all-weather suspension scaffolding device by adjusting the temperature inside the device.

By the way, even when the above-mentioned all-weather suspension scaffolding device is used, there is also a work for cleaning the outer wall when repairing the outer wall in a building, and the cleaning work is appropriately performed with water or the like. Wash water is used.

[0008] In this case, not only because the object is a high-rise building, but also for environmental protection of the surroundings, it is of course not possible to allow wash water to drain after use, and it is preferable to use it. Is the subsequent wash water drained into the regular sewer,
Alternatively, it is to be collected and reused.

However, the same applies to the above-mentioned all-weather suspension scaffolding device, but in the suspension scaffolding body of the conventional suspension scaffolding device, the floor portion set as the work scaffolding is fine with tools, bolts and nuts. Although it is configured not to drop an object, it is not configured to collect the wash water after use.

Therefore, up to now, a so-called on-the-spot use, in which the washing water after use is prevented from leaking to the outside by laying a waterproof sheet on the suspended scaffold main body, that is, on the upper surface of the floor inside the suspension scaffold It was just a simple measure.

The present invention was devised in view of the present situation as described above, and its purpose is basically to use the washing water while utilizing the suspension scaffolding to wash the outer wall of the structure. It is an object of the present invention to provide a suspension scaffolding device that is most suitable for use when cleaning.

[0012] It is preferable that the working scaffold is continuous in a circular state and is suitable for washing the outer wall of a high-rise building by using washing water while using the hanging scaffold set to be weatherproof. The purpose is to provide a scaffolding device.

[0013]

In order to achieve the above-mentioned object, the structure of the present invention is basically arranged so that it can be moved up and down along the outer wall of the structure with a suspending wire, and an appropriate connecting means. In a suspension scaffolding device having a suspension scaffolding body that is detachably linked to the outer wall of the building, the suspension scaffolding body has a storage tank on the floor set to the working scaffolding, and It is assumed that the side portion facing the outer wall has a closing body that closes a gap appearing between the side wall and the outer wall of the structure.

More specifically, it is assumed that the storage tank is disposed below the floor, and the storage tank is connected to the sewer side via a drainage pipe temporarily installed on the outer wall of the structure or to a suction pipe. It is assumed that it is connected to the washing machine side installed on the floor via the.

Further, a plurality of suspended scaffolding bodies are laterally connected along the outer wall of the structure, and each storage tank is connected between adjacent suspended scaffolding bodies by a flexible communication pipe. To do.

Further, preferably, the suspension scaffold main body has a shield structure on a side portion facing the outer wall of the construct, for closing a gap exposed between the main body and the outer wall of the construct.

[0017]

[Operation] Therefore, the storage tank stores the collected cleaning water.

At this time, the cleaning water sprayed on the outer wall of the structure is guided to the upper side of the floor by the closing body.

When the floor itself of the suspension scaffold body forms a storage tank, the wash water guided on the floor is accumulated, that is, stored on the floor.

When the storage tank is provided below the floor, the cleaning water guided on the floor is introduced into the storage tank through an opening such as a small hole formed in the floor. Recovered in
No washing water remains on the floor and the work scaffold is not soaked.

When the storage tank is connected to the sewer side through a drainage pipe temporarily installed on the outer wall of the structure, so-called drainage of washing water is made possible.

Further, when the storage tank is connected to the washing machine side installed on the floor through the suction pipe, the washing water can be reused.

On the other hand, when the suspension scaffolding device is formed by laterally connecting a plurality of suspension scaffold main bodies along the outer wall of the structure, each storage tank has a flexible communication between the adjacent suspension scaffold main bodies. By connecting with a pipe, it becomes possible to secure the required amount of washing water when the above-mentioned washing machine is used.

Further, the suspension scaffold main body fixed to a predetermined position on the outer wall of the structure is placed in a state of closing the gap appearing between the side wall of the structure facing the outer wall of the structure and the outer wall of the structure by the shielding structure. In this case, the so-called shut-off between the inside and the outside can be made possible, and in the case where necessary, for example, the temperature adjustment inside can be made possible and it can be used as an all-weather suspension scaffold.

The main body of the scaffold is distributed by a suspending wire along the outer wall of the building and is moved up and down by driving a wire winding device installed on the roof of the building.

The scaffold main body, which has been moved up and down to a predetermined position, is connected to the outer wall of the structure by an appropriate connecting means, and is detachably fixed in the vertical and horizontal directions and in the direction approaching the outer wall of the structure.

[0027]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the illustrated embodiments. Basically, a suspension scaffolding device according to an embodiment of the present invention is as shown in FIG. Similar to a kind of hanging scaffolding device, it has a hanging scaffolding main body 1 that can be lifted up and down along an outer wall A1 of a high-rise building A that is a structure with a hanging wire W.

The suspension scaffold body 1 is suspended by a suspension wire W which is wound around a pulley P provided at the upper end of the suspension scaffold body 1, and the suspension wire W extends from the roof A2 of the high-rise building A. It is connected via B to a wire winding device (not shown) which is also installed on the rooftop A2, and is set to be moved up and down by the drive of the wire winding device.

When the suspension scaffolding device has a single suspension scaffolding main body 1, the wire winding device is driven by a direct operation of an operator in the suspension scaffolding main body 1. In the case where the suspension scaffolding device has a plurality of suspension scaffolding bodies 1 in a laterally continuous state, the above-mentioned high-rise building A
It is executed by a so-called centralized control operation by a full-time worker who is in an appropriate place such as the rooftop A2.

The suspension scaffolding main body 1 is detachably fixed to the outer wall A1 of the high-rise building A by an appropriate connecting means J when the suspension scaffolding main body 1 is used except when it is moved, that is, when it is lifted.

The suspension scaffold main body 1 is fixed to the outer wall A1 of the high-rise building A in a stable state by being connected to the outer wall A1 by the connecting means J, that is, in a fixed state. When the scaffolding main body 1 is used, it will not be swung in the vertical and horizontal directions and in the direction approaching and approaching the outer wall A1.

In the illustrated example, the suspension scaffolding device is provided on the side portion 1a of the suspension scaffold body 1, that is, on the side portion 1a facing the outer wall A1 of the high-rise building A which is the left end portion in FIG. It is supposed to have a shielding structure S that closes a gap (not shown) that appears with the outer wall A1 of the high-rise building A.

In the illustrated example, the shielding structure S includes an airbag-like body S1 formed in an inverted U shape whose lower end side is a free end, and the suspension scaffold main body 1 has the connecting means J described above. In the state where the airbag-like body S1 is fixedly connected to the outer wall A1 of the high-rise building A by the
It is assumed that the compressed air is supplied from a compressed air supply source (not shown) equipped in the above to expand and close the gap in an inverted U shape.

Therefore, according to the shielding structure S, the air bag-shaped body S1 is arranged at a predetermined position in a predetermined expanded state, so that the gap is closed in an inverted U shape. It is possible to prevent rainwater and wind from entering from above and from the side.

Further, according to the shielding structure S, the inside and outside of the suspension scaffolding body 1 can be cut off by cooperation with the closing body 4 described later, and the temperature inside can be adjusted. It is also possible to set the suspension scaffolding device to be weatherproof.

The airbag-like body S1 is, in the embodiment,
It is assumed that this is formed in an inverted U shape, but instead of this, it may be formed in a ring shape, and in this case, regardless of the distribution of the closing body 4 which will be described later, blocking the inside and outside. Of course, it is advantageous that the tool and the later-described cleaning water can be prevented from falling through the gap.

Further, instead of the air bag-shaped body S1, a rubber tube-shaped body previously expanded to an appropriate thickness, or
It may be a seal-like body formed of sponge or the like in a form similar to these, but when the above-mentioned airbag-like body S1 is selected, pressure air is released when unnecessary and the airbag-like body is formed. This is advantageous in that the body S1 can be so-called compact and can be stored.

On the other hand, as shown in FIG. 2, the suspension scaffolding main body 1 according to the present invention has a storage tank 3 on the floor 2 set as a working scaffold in the suspension scaffolding main body 1, and The side portion of the floor portion 2, that is, the side portion 2a facing the outer wall A1 of the high-rise building A that is the left end portion in FIG.
In addition, it has a closing body 4 which closes a gap (not shown) that appears between the outer wall A1 and the outer wall A1 and guides cleaning water, which will be described later, to the upper side of the floor 2.

As shown in FIG. 2, the floor 2 is composed of a plate-like body 21 made of an aluminum material or the like which is lightweight and has a predetermined strength, as shown in FIG.
In the above, at the lower end portions of the pillars 5 standing upright at the so-called four corners, they are connected by appropriate connecting means such as welding and bolt tightening (not shown).

By the way, the plate-like body 21 is used for the suspension scaffold body 1
In the illustrated example, a large number of small holes 2 are formed so as to vertically penetrate the upper surface thereof, as well as being allowed to allow an operator to enter the upper surface.
It has 1a and is set so that the cleaning water accumulated on the upper surface thereof is dropped into the storage tank 3 below.

Incidentally, the small hole 21a is set to have a diameter which does not allow the passage of so-called small objects such as bolts and nuts as well as tools, and therefore, as long as the cleaning water is allowed to pass therethrough, the small hole 21a is set. Instead of the hole 21a, another opening such as a slit may be used.

In the illustrated example, a panel 6 having an appropriate height in the shape of a skirting board is arranged on the upper surface of the outer end of the floor 2 which is the right end in FIG. It goes without saying that small tools such as tools and bolts and nuts that are dropped onto the upper surface of the floor 2 are prevented from being dropped from the outer end portion to the outside.
The washing water falling on the upper surface of the floor 2 is scattered to the outside, or the washing water accumulated on the upper surface of the floor 2 leaks to the outside before being dropped into the storage tank 3 through the small holes 21a. I am careful not to.

The storage tank 3 is the floor portion 2 in the illustrated example.
And is formed under an aluminum plate having a predetermined strength while being lightweight, and is formed in a box shape having an opening at the upper end.

The storage tank 3 is connected to the lower end portion of the column 5 by an appropriate connecting means such as welding or bolt tightening (not shown), and the storage tank 3 is internally provided through the small hole 21a from the floor portion 2a. It is set so that the wash water that falls can be collected and stored.

The upper end of the storage tank 3 is in the illustrated example,
It is assumed that it is not connected to the lower surface of the floor portion 2, but if necessary, it may be connected to the lower surface of the floor portion 2 by an appropriate connecting means such as welding or bolt tightening. is there.

Since the storage tank 3 is disposed below the floor portion 2, the operator can add a foot to the collected cleaning water as compared with the case where the floor portion 2 also serves as the storage tank 3 directly. It is possible to avoid problems such as continuing work while soaking.

When the floor 2 directly serves as the storage tank 3, a skirting board similar to the panel 6 is arranged on the four sides of the upper surface of the floor 2. Aside from the case where the main body 1 is used alone, the suspension scaffold main body 1
When multiple is used in the horizontal direction,
In particular, there is a fear that the lateral baseboard-like arrangement may become an obstacle that obstructs the walking of the worker.

Therefore, it is preferable that the storage tank 3 is arranged below the floor portion 2. However, in the illustrated example, the cleaning water stored in the storage tank 3 is The drainage pipe 32 connected to the drain pipe 31 connected to the storage tank 3 is connected to the sewer (not shown) side.

Since the storage tank 3 is connected to the sewer side via the drainage pipe 32, drainage from the storage tank 3 to the outside becomes possible, and the weight of the washing water in the suspension scaffold body 1 is increased. It is advantageous in that it can be blocked in advance.

The drain pipe 31 has a length such that its lower end does not project downward from the lower end of the pillar 5 described above, and does not become an obstacle when the suspension scaffold body 1 is placed on the ground or the like. Is considered.

Further, since the middle portion of the drainage pipe 32 is fixed to the outer wall A1 of the high-rise building A by a temporary bracket 32a, so-called fluttering due to water pressure or wind at the time of drainage is said to be prevented.

The closing body 4 is the outer wall A1 of the high-rise building A.
When the washing water is washed with the washing water, it is provided to guide the used washing water to the upper side of the floor 2, that is, the upper side of the storage tank 3.

For that purpose, it is necessary for the closing body 4 to close the gap appearing between the side portion 2a of the floor 2 and the outer wall A1 of the high-rise building A, and therefore, In the illustrated example, the closing body 4 is laterally formed of an aluminum material or the like which is lightweight but has a predetermined self-supporting property.

Explaining a little, the closing body 4 has a flat plate portion 41 that is a main body portion that substantially closes the gap, and a reinforcing portion 42 that reinforces the flat plate portion 41 from below.
The flat plate portion 41 and the reinforcing portion 42 are previously integrated by welding or the like, and the flat plate portion 41 is detachably connected to the floor portion 2 by using a bolt 43, so that the side portion 2a of the floor portion 2 is connected. It will be installed.

Therefore, in this embodiment, the flat plate portion 4
1 is the flat plate portion 4 on the base end side thereof in the left-right direction in FIG.
1 has an elongated hole 41a which is opened along the axial direction of 1 and is aimed at a screw hole (not shown) which is previously opened in the lower floor portion 2. The bolt 43 is inserted and the bolt 43 is screwed into the screw hole from this state.

Incidentally, the screw hole may be formed by forming the small hole 21a in the floor portion 2 into a screw hole and diverting it to the screw hole referred to here. This is advantageous in that a screw hole need not be provided separately from the small hole 21a.

Also, in this embodiment, the reinforcing portion 42
2 has a flange portion 42a at the base end that is the right end in FIG. 2, and the flange portion 42a becomes the side portion of the storage tank 3, that is, the left end portion in FIG. 2, of the high-rise building A. The flat plate portion 41 is brought into contact with the side portion 3a facing the outer wall A1.
It is set so as to prevent so-called tilting of the tip side of the.

A seal 44 is fixedly connected to the tip of the flat plate portion 41, and if the tip of the flat plate portion 41 directly contacts the outer wall A1 of the high-rise building A, it will occur there. The seal 44 closes a small gap that would otherwise occur.

In the illustrated example, the seal 44 is made of a rubber material and formed into a tube having an appropriate thickness, but the point is that the seal 44 is set so that a slight gap does not appear as described above. Therefore, in that respect, a free form can be selected.

Therefore, the closing body 4 formed as described above
In this case, the cleaning water sprayed on the outer wall A1 of the high-rise building A and flowing down on the outer wall A1 is the seal 44 and the flat plate portion 4.
1 flows over the upper surface of 1 to flow onto the floor 2 and is collected in the storage tank 3 below the floor 2. In particular, the inconvenience that the cleaning water falls outside through the above-mentioned gap is caused. It will be possible to prevent it.

Further, in the closing body 4, when the airbag-like body S1 forming the shielding structure 3 is formed in a ring shape and has a so-called lower end side, the closing body 4 is closed. The lower end side of the body S1 is so-called covered from above so as to be protected, and the airbag body S1 can be protected from fireballs or the like during welding work.

By the way, when the flat plate portion 41 is set so as to be so-called flush with the floor portion 2 as in the above-mentioned embodiment, an operator on the floor portion 2 is placed on the flat plate portion 41. There is a fear of entering.

At this time, if the closing body 4, that is, the structure portion including the flat plate portion 41 and the reinforcing portion 42 is set to have sufficient strength, the closing body 4 is used as an extension of the floor portion 2. Although there is an advantage that it can be operated, it is preferable to prevent an operator from entering.

FIG. 3 shows an embodiment in which an operator is prevented from standing on the closing body 4, that is, the flat plate portion 41, and the structure portion including the flat plate portion 41 and the reinforcing portion 42 is the floor portion. It is said that the bracket portion 45 which stands up at the end portion of the second portion 2 and constitutes the side portion 2a of the floor portion 2 is continuously provided by using bolt nuts 46 and 47.

In the case of this embodiment, since the upper surface of the flat plate portion 41 is higher than the upper surface of the floor portion 2 by the amount of the bracket portion 45, an operator on the floor portion 2 is necessarily placed on the flat plate portion 41. It will be possible to keep out.

Therefore, in this embodiment, it is not necessary to form the closing body 4, that is, the structural portion composed of the flat plate portion 41 and the reinforcing portion 42, more robustly as compared with the above-mentioned embodiments, and as a result, This is advantageous in that the overall weight of the suspension scaffold body 2 can be reduced.

By the way, in the case of each of the above-mentioned embodiments,
It is assumed that the closing body 4 is fixedly connected to the side portion 2a of the floor 2, but instead of this, as shown in FIG. 4, it may be rotatably arranged.

That is, the closing body 4 in this embodiment is
It is assumed that the flat plate portion 41 is formed in a hinge structure (not shown), and the base end side portion 41b of the flat plate portion 41 corresponding to one wing of the hinge has the bolt 4 as in the case of the embodiment shown in FIG.
3 is used or is connected to the upper surface of the floor portion 2 by welding or the like.

The flat plate portion 41 corresponding to the other wing of the hinge
A reinforcing portion 42 is continuously provided on the lower surface side of the tip end side portion of the flat plate portion 41 and is set so as to prevent so-called tilting of the flat plate portion 41 on the tip end side thereof, as in the case of the embodiment shown in FIG. Is going to be.

Further, in this embodiment, the flat plate portion 4
1 has a strip-shaped body 48 made of a highly flexible plate rubber in place of the seal 44 described above, and the strip-shaped body 48 is set to a so-called marginal length,
Consideration is given so that the gap between the tip of the flat plate portion 41 and the outer wall A1 of the high-rise building A can be slightly changed.

A band-shaped body 48 which replaces the seal 44 is provided.
Needless to say, may be applied to the case of the embodiment of FIG.

Therefore, in the case of the embodiment shown in FIG. 4, it is possible to rotate the closing body 4 as indicated by the imaginary line arrow in the figure, and the so-called phantom diagram in the figure is called. When the closed scaffold 4 is placed in the closed state, the suspension scaffold body 1
It is advantageous in that it will not become an obstacle when going up and down.

In the case of the embodiment shown in FIG. 4, and
In the case of the embodiment shown in FIG. 2, it is preferable that an appropriate display for prohibiting entry is provided on the upper surface of the flat plate portion 41.

FIG. 5 shows a suspension scaffolding device according to another embodiment of the present invention, in which the suspension scaffolding device has a plurality of suspension scaffolding bodies 1 continuous in the lateral direction, which is the left-right direction in the drawing. It is supposed to be in a state in which

In this embodiment, the adjacent suspension scaffold main bodies 1 are connected by the link structure 7, and
It is supposed that the storage tanks 3 between the adjoining suspended scaffolding bodies 1 are connected to each other via a water distribution pipe 31 by a flexible communication pipe 33.

In this embodiment, the cleaning water collected in the storage tank 3 is reused by using the cleaning machine 8.

As described above, the reason why the adjacent storage tanks 3 are connected to each other by the flexible communication pipe 33 is that the cleaning water after use is collected and the cleaning machine 8 is used. This is because it is convenient for reuse, and secondly, because it corresponds to a structure in which adjacent suspension scaffolding bodies 1 are connected by a link structure 7.

That is, when using the washing machine 8, it is necessary to prevent the washing machine 8 from running idle, so that the washing machine 8 does not run idle, so that a sufficient amount of washing water can be secured for each other. The storage tanks 3 to be connected are connected by a so-called pipe.

Further, when the suspension scaffolding device is raised and lowered in a state where the plurality of suspension scaffolding bodies 1 are laterally continuous, even if the suspension scaffolding bodies 1 are raised and lowered in synchronization, the suspension scaffolding bodies 1 are actually synchronized. There is a case where a so-called competition occurs without being carried out, and the link structure 7 is provided in order to prevent the situation of being unable to move up and down due to this bidding in advance.

Therefore, the suspension scaffolding device can be moved up and down by the action of the link structure 7 without competing, and in order to connect the adjacent storage tanks 3 without obstructing the action of the link structure 7. The communication pipe 33 is provided.

Incidentally, the cleaning machine 8 sucks the cleaning water from the storage tank 3 through the suction pipe 34 and reuses the cleaning water through the injection pipe 81.

Even in this embodiment, the floor portion 2, the storage tank 3, the closing body 4, and the pillars 5 constituting the suspension scaffold body 1 are
It has the same configuration as in the above-mentioned embodiment, and
Although not shown, the airbag-like body S that constitutes the shielding structure S
1 and the panel 6 and the like, the configuration is similar to that of the above-described embodiment, so detailed description of the functions and functions thereof will be omitted.

From the above, according to this embodiment, it is possible to avoid in advance a problem such as the worker continuing his work while dipping his feet in the collected cleaning water, as in the above-described embodiment. Of course, the cleaning water that may contain chemicals or the like is not discharged to the sewer side, and the cleaning water is reused to enable effective use of the cleaning water.

In this embodiment, it is needless to say that the selected storage tank 3 may be set so as to be communicated with the sewer side under the presence of valves.

Further, in the embodiment without the washing machine 8, the washing water is generally supplied from the rooftop A2 of the high-rise building A by a pressure hose.

[0086]

As described above, according to the present invention, when the outer wall of the building is washed by using the wash water while utilizing the suspended scaffold, the wash water sprayed on the outer wall of the construct is occluded by the blocker. Since it is guided and collected in the storage tank through the floor, the wash water after use does not leak to the outside of the suspension scaffold body, and the outer wall of the structure below the suspension scaffold body does not get wet. Of course, there is an advantage that the environment can be preserved because it is not scattered around the outer wall of the structure.

When the storage tank is arranged below the floor, the worker dips his / her feet in the collected cleaning water as compared with the case where the floor directly serves as the storage tank. There is an advantage that problems such as continuing work can be avoided in advance.

When the storage tank is connected to the sewer side via the drainage pipe, the washing water after use is not drained, and the weight of the suspension scaffold body is not increased. There are advantages.

Further, when the storage tank is connected to the washing machine side through the suction pipe, there is an advantage that the collected washing water can be reused so that the washing water can be effectively used. .

Further, when a plurality of suspended scaffolding bodies are laterally connected along the outer wall of the structure, and each storage tank is connected between adjacent suspended scaffolding bodies by a flexible communication pipe. In this case, there is an advantage that it becomes easy to secure the required amount of washing water, especially when using the above-mentioned washing machine.
