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 scaffold for forming a so-called working scaffold on the outside of a structure when building the structure.

[0002]

2. Description of the Related Art Conventionally, work scaffolds are generally provided outside a building when building a building such as a middle-high-rise building, especially when the building is a low-rise building. It is easy to provide a work scaffold by extending the so-called group scaffold from the ground.

However, when the structure is a high-rise building, it is not easy to extend the assembled scaffolding from the ground to provide a work scaffolding. Therefore, the applicant of the present application has already proposed a hanging scaffolding (Tobic ... registered trademark). Are offered.

The suspension scaffolding is configured to form a work scaffolding for one worker by suspending the suspension scaffolding outside the structure, which is a combination of a pillar part and a beam part, which are the body part of the structure. There is.

Therefore, it is necessary to prepare the suspension scaffolding in a quantity corresponding to the number of united portions of the column portion and the beam portion. Therefore, even if the suspension scaffolding is formed to be foldable, it is not used. It has the disadvantage of requiring a large space for time storage.

Since the suspension scaffolding is required to be transferred for use, it is essential that the suspension scaffolding be made small and lightweight. Therefore, it is not suitable for use when a wide working scaffolding is required, and the impact is also great. It is apt to be deformed due to such reasons as being inconvenient for handling during transportation and storage.

Further, the suspension scaffold is constructed so as to be suitable for use when the structure is still in a skeletal state, that is, when the column portion and the beam portion made of steel are combined. After the sections and beams are covered with concrete and finished, there is a disadvantage that it cannot be used.

The present invention was devised in view of the above-mentioned circumstances, and an object thereof is to make it possible to secure a wide working scaffold and to enable normal handling during transportation and storage. Moreover, even if the body part of the structure is in a completed state, it can be used, and a multi-layer suspended scaffold that is optimal for use in scaffolding when constructing structures such as middle-high-rise buildings Is to provide.

[0009]

In order to achieve the above-mentioned object, a multi-layer suspension scaffold according to the present invention is provided with a scaffolding body having multiple stages of scaffolding and distributed outside the structure, The hanger frame is connected to the scaffolding body, and the hanger bracket is connected to the hanger frame at its tip end side and its base end side is connected to the body portion of the construct.

More specifically, it is assumed that the hanger frame is fixedly connected to the scaffolding body and connected to the hanger bracket so that the connecting position can be adjusted.
It is assumed that the base end of the hanger bracket is detachably connected to the body of the structure, and that the multi-stage scaffolding of the scaffolding is continuous with ladders or stairs.

Further, while the hanger bracket is arranged on the upper end side of the scaffolding body, the hanger bracket or the connecting material is arranged on the lower end side of the scaffolding body, and the connecting material adjusts the connecting position of the tip end side thereof to the scaffolding body. It is assumed that it is configured to be movably connected and its proximal end side is separably connected to the body portion of the construct.

[0012]

Therefore, the hanger frame is integrally connected to the scaffolding body disposed outside the structure so as to be along the pillar portion forming the body part of the structure, and the tip side of the hanger bracket is connected to the hanger frame. By connecting and connecting the base end side of the hanger bracket to the beam portion or the column portion that constitutes the body portion of the structure, it is possible to provide a hanging scaffold that forms a work scaffold outside the structure.

When connecting the hanger frame to the hanger bracket, the connecting position of the hanger frame to the hanger bracket can be moved and adjusted in the axial direction of the hanger bracket on the tip side of the hanger bracket.

When adjusting the connecting position of the hanger frame to the hanger bracket, the position of the scaffolding body suspended on the hanger bracket is set, that is, the position of the scaffolding body away from the outer wall of the structure. Can be selected.

Since the scaffold has a plurality of scaffolds and is extended in the vertical direction, scaffolds extending over several floors are formed, and the scaffolds continue the multistep scaffolds with ladders or stairs. This creates a wide working scaffold.

Further, since the hanger bracket is connected to the upper end side of the scaffolding body and the hanger bracket or the connecting material is connected to the lower end side of the scaffolding body, the wind outside the structure on the lower end side of the scaffolding body is provided. It is possible to effectively prevent swaying caused by the above.

Further, the hanger frame or the hanger bracket, the scaffolding body, and the beam portion or the column portion forming the body portion of the structure are appropriately connected by a wire rope or the like to construct the structure of the scaffolding body. The arrangement state outside of the is further stabilized.

The scaffolding board 13 is provided between the short lateral base materials 12 arranged in the width direction, and the scaffolding board 13 forms the scaffolding.

The scaffolding body 1 is an example shown in the figure, and a multi-stepped scaffold consisting of the scaffolding plate 13 is used to form a large number of short lateral materials 12.
Continuing with the ladder 14 formed in (1) ensures a wide scaffold continuous in the vertical direction.

Incidentally, in place of the ladder 14, the upper and lower scaffolding plates 13 may be connected to each other by a stair separately provided, though not shown.

The size of the horizontal plane of the scaffolding body 1, that is, the size of the scaffolding plate 13 is appropriately set, but it is preferably about 1800 × 680 mm. In this case, , For example, two workers simultaneously use the scaffolding plate 13
It becomes possible to step up and place equipment such as a welder on the scaffolding plate 13.

By the way, in this embodiment, the scaffold 1
Is supposed to be formed by using a member configured as follows.

That is, as shown in FIG. 3, the vertical base material 11 constituting the scaffolding body 1 is made of a steel pipe having an appropriate outer diameter, and has a length substantially similar to that which a scaffolding device of this type usually has. In addition, the horizontal flange body 10 formed in an annular shape is continuously provided on the outer circumference of the horizontal flange body 10 at appropriate intervals in the vertical direction.

The horizontal flange body 10 is for connecting the long and short horizontal base materials 12 constituting the scaffold body 1, and the horizontal base material 12 is made of a steel pipe having an appropriate outer diameter. It is set to 1800 mm and 680 mm.

By the way, as shown in FIGS. 4 and 5, the horizontal flange body 10 is formed so as to have a dovetail groove-shaped cross section. It has an annular locking portion 101.

The horizontal flange body 10 has its inner peripheral side continuously connected to the outer periphery of the vertical ground material 11 by welding, and has a locking portion 101 on the outer peripheral side thereof, for example, in the form shown in FIG. It is possible to connect the formed horizontal base materials 12.

That is, the horizontal base material 12 has shoes 2 formed so as to sandwich the horizontal flange body 10 at both ends thereof.
The shoe 20 has a hook 203 that retracts when the wedge 201 is retracted and that is advanced by the biasing force of the spring 202 when the wedge 201 retracts.

The hook 203 is formed so that its tip end engages with the engaging portion 101 when it is retracted.

Therefore, the shoe 20 is connected to the horizontal flange body 10, and the wedge 201 is connected to the shoe 20.
By being driven into, the horizontal base material 12 can be fixedly connected to the vertical base material 11.

Although not shown, the vertical base material 11 is assumed to be continuous in the vertical direction by connectors provided at the upper and lower ends thereof.

Further, on the horizontal flange body 10 of the vertical base material 11, as shown by an imaginary line in FIG. 2, the horizontal base material 12 arranged in the length direction is similar to the horizontal base material 12 in the width direction. Of course, it is connected to.

As described above, the scaffolding body 1 is constituted by the vertical base material 11 having the horizontal flange body 10 and the horizontal base material 12 having the shoes 20 as described above, so that the scaffold body 1 is extremely long. It becomes possible to form a scale and the structure A
This enables the use of multi-story suspended scaffolding even when the building is considered as a high-rise building.

Further, in the scaffolding body 1 composed of the vertical base material 11 and the horizontal base material 12, at the time of dismantling, the scaffold body 1 is separated and conveyed and managed for each component, while It is also possible to form the so-called scaffolding device and the strut device by diverting each component of the above.

The hanger frame 2 is provided in order to surely and easily suspend the scaffolding body 1 by the hanger bracket 3 described later, and the hanger frame 2 itself is provided.
Function to hang.

Therefore, in the illustrated example, the hanger frame 2 is composed of a frame body 21 having a rectangular planar shape as shown in FIG. 2, and the length dimension of the frame body 21 is the scaffolding plate. The width of the scaffolding plate 13 is set to be larger than the length of the scaffolding plate 13, while the width of the scaffolding plate 13 is set to be substantially the same.

In the illustrated example of the hanger frame 2, a footboard 22 used as a foothold is extended at a position overlapping the footboard board 13 in the vertical direction, and an opening 23 is formed in the footboard 22. It has a lid 24 that is formed and that opens and closes the opening 23, and the opening of the lid 24 enables communication with the upper or lower scaffold space.

Further, the hanger frame 2 has a suspender 25 at an appropriate position on the upper end side thereof, and the suspender 25 can be used to suspend the hanger frame 2 by a crane or the like. There is.

By the way, the connection between the hanger frame 2 and the vertical base material 11 constituting the scaffolding body 1 has a structure as shown in FIG. 6 in the illustrated example.

That is, the frame members 21 constituting the hanger frame 2 have an appropriate interval, that is, an interval corresponding to the interval between the vertical members 11 arranged when forming the scaffold 1.
The upper and lower end surfaces thereof have an opening 21a which is opened, and the connecting rod 301 is inserted through the opening 21a so that the vertical base material 11 is separably connected to the upper and lower ends of the connecting rod 301. .

The opening 21a is reinforced by a ring seat member 302 welded to the upper and lower end surfaces of the frame 21 so that the opening 21a is aimed from the outside.
Has a notch 302a in a part thereof, as shown in FIG.

Although not shown, notches, which are not shown, are formed on the upper and lower end faces of the frame 21 adjacent to the so-called back surface of the notches 302a.

By the way, the connecting rod 301 is set so that the outer diameter thereof is slightly smaller than the inner diameter of the vertical base material 11, and the bulge expanded to the outer peripheral side at the upper end side thereof. As shown in FIG. 8, the portion 301a has two pins 303 and 30 which are horizontally arranged and maintain an angle of 90 degrees with each other in the upper and lower stages.
4 is included.

The diameters and protruding lengths of the pins 303 and 304 are set so as to be slightly smaller than the width and length of the cutout portion 302a in the ring seat member 302.
In the illustrated example, the formation is performed by forming a rod body having a diameter smaller than that of the connecting rod 301 in a hole (not shown) opened so as to penetrate the intermediate portion of the connecting rod 301 in the radial direction, that is,
It is said to be realized by inserting the pins 303 and 304.

Incidentally, the base ends 3 of the pins 303 and 304 are
03a and 304a are slightly enlarged in diameter, and the base end portion 3
03a and 304a are press-fitted into the intermediate portion of the connecting rod 301 in a hole that is opened in the radial direction to prevent the connecting rod 301 from falling off.

Further, the connecting rod 301 has through holes 301b formed at the upper and lower ends thereof so as to penetrate the respective end portions in the radial direction, and the through holes 301b.
The connecting pin 305 is supposed to be inserted therethrough.

At the upper and lower ends of the vertical base material 11, openings 11a aimed at the through holes 301b are provided.
Is pierced in such a manner as to pass through in the radial direction, and is set so as to allow insertion of the connecting pin 305.

A retaining pin 306 is inserted into the tip of the connecting pin 305.

Therefore, in the case of the connection structure of the hanger frame 2 and the vertical material 11 as described above, the connection rod 301 is inserted into the opening 21a of the frame body 21 forming the hanger frame 2 and By connecting the vertical material 11 that constitutes the scaffolding body 1 to the connecting rod 301, the hanger frame 2 and the scaffolding body 1 can be connected.

However, when the connecting rod 301 is inserted into the opening 21a of the frame body 21, the pins 303 and 304 projecting from the connecting rod 301 are inserted into the notches 302a formed in the ring seat member 302. It will be operated like.

That is, first, the lower pin 304 has the notch 3
After passing through 02a, the connecting rod 301 is once rotated in the horizontal direction by 90 degrees, and then the upper pin 303 is passed through the notch 302a, and finally, the connecting rod 301 is also rotated in the horizontal direction by approximately 90 degrees. To operate.

As a result, the frame body 2 of the connecting rod 301
Separation from 1 becomes impossible and completed scaffold 1 unless horizontal rotations of 90 degrees are performed twice.
In the above, the horizontal rotation of only the vertical material 11 as described above cannot occur, and therefore, in practice, the fixed and complete connection state is maintained.

Incidentally, it goes without saying that the connection state between the hanger frame 2 and the scaffolding body 1 may be maintained by using, for example, bolts and nuts.

As shown in FIG. 9, the hanger bracket 3 suspends the scaffolding body 1 so as to support the hanger frame 2, and the base end side thereof constitutes the beam portion A2 which constitutes the skeleton portion of the structure A. Connected to.

It is said that it is detachably connected to the mounting portion B1 by using bolts and nuts.

The arm portion 31 has a large number of bolt holes 31a opened on its side surface at appropriate intervals.
a is arranged in the axial direction of the arm portion 31 which is the left-right direction in the drawing.

Then, the hanger frame 2 is detachably connected to the hanger bracket 3 through the bolt holes 31a by using bolts and nuts.

Therefore, in the illustrated example, by selecting the bolt hole 31a, it is possible to dispose the hanger frame 2 near the outer wall of the structure, etc., as shown in the phantom diagram in the figure. The arrangement position of the scaffolding body 1 suspended on the hanger bracket 3, that is, how far the scaffolding body 1 is set from the outer wall of the structure A can be selected.

Incidentally, a bracket 31a is provided so as to project from the tip of the hanger bracket 3, that is, the tip that is the left end in the figure of the arm 31, and the bracket 31a hangs down from the top of the construction A or the like. It is supposed that the ends of the hanging wires W are bound together if necessary.

In the illustrated example, the cane portion 32 is formed in a bifurcated shape, and the lower end is positioned at the base end side of the arm portion 31 while the upper end is at the tip end side of the arm portion 31. The main body 32a that is positioned at the center and extends obliquely, and the arm 3

The beam portion A of the hanger bracket 3
In the illustrated example, the seat portion 33b at the tip of the abutting member 33 is abutted against the beam base material B that constitutes the beam portion A2 in connection with the connection to the beam 2, but as shown in the phantom diagram in FIG. When the beam portion A2 is completed by concrete pouring, the seat portion 33b of the abutting member 33 has the beam portion A2.
In this case as well, the scaffold 1 can be suspended by the hanger bracket 3 as well.

As a result, in the case of the hanger bracket 3 of this embodiment, it is possible to use what is so-called set before the completion of the beam portion A2 and continuously use it even after the completion of the beam portion A2. There is.

In the illustrated example, it is assumed that the cane portion 32 is integrally connected to the arm portion 31, but instead of this, the cane portion 32 is provided to the arm portion 31. It may be formed to be separable, and the connecting position thereof may be freely changed in the axial direction of the arm portion 31.

FIG. 10 shows another embodiment of the hanger bracket 3. In this embodiment, the hanger bracket 3 is attached to the beam portion A2 forming the body portion of the structure A at the base end thereof. The hook members 34 to be stopped are connected.

FIGS. 11 and 12 show still another embodiment of the hanger bracket 3, in which the hanger is used in the case of each of the embodiments shown in FIGS. 9 and 10 described above. Instead of assuming that the base end of the bracket 3 is connected to the beam portion A2 forming the body portion of the structure A,
It is assumed that the base end of the hanger bracket 3 is connected to a holding mechanism and is connected to the pillar portion A1 that constitutes the body portion of the building A by the holding mechanism.

That is, in the embodiment, the hanger bracket 3 has the scaffolding 1 at the tip end side thereof and the hanger frame 2

By adjusting the tension of 2, the so-called fixation of the lower end side of the scaffolding body 1 becomes possible, and the swinging of the lower end side of the scaffolding body 1 whose upper end side is suspended by the hanger bracket 3 is prevented.

FIG. 14 shows another embodiment of the connecting member 4, and the connecting member 4 has a holding mechanism 43 at the base end side thereof.
And the holding mechanism 43 holds the body part of the construction A.

That is, the sandwiching mechanism 43 has a structure in which the inner rod 43b is retracted from the outer tube 43a, and the outer tube 43a is clamped by the clamp 4.
It is assumed that the vertical base material 11 forming the scaffolding body 1 is fixedly connected by 3c.

The outer tube 43a has a holding piece 43d at the right end in the figure,
It is assumed that the inner rod 31b has a holding piece 43e at the right end in the figure, and the holding piece 43e and the holding piece 43d face each other.

FIG. 15 shows another embodiment of the multi-layer suspension scaffold. The multi-layer suspension scaffold of this example is set so as to be arranged at a so-called corner portion of the structure A. .

That is, as shown in FIG. 16, the scaffold 1 is
It is assumed that the planar shape is formed so as to have a so-called rectangular shape, and thus a rectangular work scaffold is formed outside the corner of the structure A.

Incidentally, the scaffold 1 is
As in the previous embodiment, the horizontal flange body 10
It is supposed that it is formed by a combination of the vertical ground material 11 having the above and the horizontal ground material 12 having the shoe 20 and the construction of the scaffolding plate 13.

Next, as shown in FIG. 15, the hanger frame 2 is designed to efficiently support the scaffold 1 as described above.

[0105] Then, changing the location of the multi-layer suspension scaffold,
That is, the refilling is realized by moving the scaffolding body 1 separated from the structure A by using a crane or the like.

When the scaffolding body 1 is constructed so that it can be disassembled into its constituent parts, it can be diverted to a member forming a scaffolding device, a supporting column device or the like when it is not used. It will be possible.

[0107]

As described above, according to the present invention, it is possible to form a work scaffold that is continuous in the vertical direction outside the structure and along the pillar part that constitutes the body part of the structure. In addition, when this is continued by ladders or stairs, there is an advantage that a wide working scaffold that is continuous in several floors, that is, in the vertical direction is secured.

Further, according to the present invention, the work scaffold is so-called fixedly formed, and since a crane or the like is used during movement, it is possible to form a robust work scaffold. It is possible to install the device, and it is possible to improve the work efficiency of various works.

Further, according to the present invention, it becomes possible to install the work scaffold until the end of the construction.
It is possible to use the work scaffold at any time for repairing useless construction, and there are advantages such as improving the progress of the entire construction.

Furthermore, according to the present invention, it is possible to dispose the hanger frame closer to the outer wall of the structure, and the disposition position of the scaffolding body hung on the hanger bracket, that is, the scaffolding body is used as the outer wall of the structure. There is an advantage that it is possible to select how far away from the position.
