Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a multi-layer suspension scaffold which forms a multi-stage continuous suspension scaffold on the outside of a structure when the structure is built.

[0002]

2. Description of the Related Art Conventionally, when building a structure such as a middle and high-rise building, it is common to provide a scaffold outside the structure, especially when the structure is a low-rise building. It is also easy to provide the scaffold as a combined scaffold extending upward from the ground.

However, when the structure is a high-rise building, it is not easy to provide the scaffolding with a scaffolding from the ground, so the applicant of the present application has already suspended the scaffolding (Tobic ... registered trademark).
Are offered.

This suspension scaffolding is constructed so that a scaffolding for one operator is provided by suspending it from the outside of the construction at a united portion of a pillar portion and a beam portion which are the body portion of the construction.

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 must be transported during use, it is important that the suspension scaffolding be made small and lightweight. Therefore, it is unsuitable for use when a wide scaffolding is required, and shocks and the like are required. It is apt to be deformed due to the above, and there is a problem that sufficient consideration is required 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 its purpose is to make it possible to secure a wide hanging scaffold and to allow normal handling during transportation and storage. Moreover, it is possible to use it even if the body part of the structure is in a completed state, and by providing a multi-layer suspended scaffold that is optimal for use when building a structure such as a middle-high-rise building. is there.

[0009]

In order to achieve the above-mentioned object, the structure of the multi-layer suspended scaffold according to the present invention has a structure in which a multi-stage scaffold is continuously formed by a ladder or stairs while being formed into a rigid structure. While connecting the scaffolding body that is distributed outside the structure along the pillar portion that constitutes the hanger frame, the hanger frame that is integrally connected to the scaffolding body, and the hanger frame to the tip side so that the connection position can be adjusted. A hanger bracket, the base end side of which is separably connected to the body part of the structure; and the hanger frame is connected to a connecting rod that enables connection of vertical vertical members composing the scaffolding body. It is assumed that the hanger bracket is separably connected to a beam portion or a column portion or a beam base material forming the beam portion, which is a body portion of the structure, directly or to an attachment portion continuous to the beam base material.

Preferably, the connecting rod connects the upper and lower end portions to the vertical base material forming the scaffolding body and the middle portion to the frame body forming the hanger frame in a retaining structure.

Further, a hanger bracket is arranged on the upper end side of the scaffolding body, while a hanger bracket or a connecting member is arranged on the lower end side of the scaffolding body, and the connecting member can adjust the connecting position of the tip end side to the scaffolding body. And the proximal end side is separably connected to the body portion of the construct.

[0012]

[Operation] Therefore, the hanger frame is integrated with the scaffold distributed outside the structure along the pillars that form the structure of the structure by connecting multiple stages of scaffolds with ladders or stairs while forming a rigid structure. Of the hanger bracket to the hanger frame so that the position of the hanger bracket can be adjusted and the base end side of the hanger bracket is formed into a beam portion or a pillar portion or a beam portion that constitutes the body portion of the structure. The scaffold can be formed on the outside of the structure by being separably connected to the beam base material to be formed or directly to a mounting portion continuous to the beam base material.

At this time, since the scaffolding body is set to have a rigid structure, compared to the case where it is formed to have a flexible structure such as a so-called rope ladder, a fixed portion that is less susceptible to shaking due to wind pressure or the like is provided. Only by providing the required stability, it is possible to form a robust scaffolding, for example, it is possible to place a welder, etc., and at the time of movement, it is possible to use a crane, etc. Enables improvement of work efficiency of various works.

Further, when the connecting position of the hanger frame to the hanger bracket is adjusted in the axial direction of the hanger bracket, the position of the scaffold suspended on the hanger bracket, that is, the scaffold is separated from the outer wall of the structure. It becomes possible to select how far away the position is set.

When a multi-stage scaffold is vertically continued by a ladder or stairs, the scaffolding body forms a wide scaffold covering several floors.

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

Furthermore, when 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, the structure of the scaffolding body is formed. The state of arrangement outside the vehicle is further stabilized.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Explaining the preferred embodiments below, as shown in FIGS. 1 and 2, a multi-story suspended scaffold according to an embodiment of the present invention has a multi-tiered structure outside a building A such as a high-rise building. A scaffold body 1, a hanger frame 2, and a hanger bracket 3 are formed to form a suspended scaffold that is a continuous scaffold.
And a connecting member 4.

The scaffolding body 1 is arranged outside the structure A in the longitudinal direction, that is, along the pillar portion A1 which constitutes the body part of the structure A, and is arranged at so-called four corners. A plurality of (4) vertical materials 11 that are positioned and parallel to each other
And a plurality of long and short parts which are arranged in the width direction (left and right direction in FIG. 1) and the longitudinal direction so as to connect the vertical base materials 11 adjacent to each other and are connected to the vertical base material 11. Horizontal material 12,
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 preferably about 1800 × 680 mm. In this case, for example, It becomes possible for two workers to enter the scaffolding plate 13 at the same time, or to mount equipment such as a welder on the scaffolding plate 13.

By the way, in this embodiment, the scaffold 1
Is said to be formed into a rigid structure 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 fixed connection of the horizontal base material 12 to the vertical base material 11, that is, the connection of the rigid structure becomes possible.

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, since the scaffolding body 1 is composed of the vertical base material 11 having the horizontal flange body 10 and the horizontal base material 12 having the shoes 20, it is of course set to a rigid structure. The scaffolding body 1 can be formed in an extremely long state, and even when the building A is a super high-rise building, the multi-layer suspended scaffolding can be used.

Since the scaffold 1 is set to have a rigid structure, the scaffolding 1 is less susceptible to swaying due to wind pressure, etc., as compared with a conventional one having a flexible structure such as a so-called rope ladder. The required stability can be obtained by providing only a few fixing points.

Further, in the scaffolding body 1 composed of the above-mentioned vertical base material 11 and the horizontal base material 12, at the time of disassembling, this is separated and conveyed and managed for each component part, 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 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, the hanger frame 2 has a footboard 22 which is used as a foothold at a position overlapping with the footboard 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 retaining structure as shown in FIG. 6 in the illustrated example.

That is, the frame bodies 21 constituting the hanger frame 2 have an appropriate interval, that is, an interval corresponding to the interval between the vertical base materials 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 body 21 so as to be aimed at the opening 21a from the outside.
Has a notch 302a in a part thereof, as shown in FIG.

Although not shown, notches, which correspond to the so-called back surface of the notch 302a, are formed in the upper and lower end surfaces of the frame 21.

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 bulging is enlarged on the upper end side to the outer peripheral side. 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 base material 11 as described above, the connection rod 301 is inserted into the opening 21a of the frame body 21 constituting 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 protruding 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 is provided with the cutout 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 retaining structure is maintained to maintain the fixed and complete connection state.

It is needless to say 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 of the hanger bracket 3 constitutes a 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 by using bolts and nuts through the bolt holes 31a.

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 construction, 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, at the tip of the hanger bracket 3, that is, at the left end of the arm portion 31 in the figure, a bracket 31a is projectingly provided, and the bracket 31a hangs down from the upper portion of the construction A or the like. The ends of the hanging wires W to be formed are bound as necessary.

In the illustrated example, the cane portion 32 is formed into 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 abutting member 33 is a rod-shaped main body portion 33a which extends horizontally from the tip end side of the arm portion 31 toward the base end side and penetrates the base portion 32, and in the figure of the main body portion 33a. The rear end side is screwed to the front end that is the right end, and the seat portion 33b that is retracted at the front end of the main body portion 33a by the rotation thereof is provided.

Further, holes 33c penetrating in a direction traversing the body portion 33a are formed at appropriate intervals on the rear end side of the body portion 33a, and bolts (penetrating in a direction traversing the base portion 32 in the hole 33c ( By inserting (not shown), the position fixing of the main body 33a with respect to the base 32 is realized.

Therefore, in the hanger bracket 3 configured as described above, the base end side of the arm 31 constitutes the body part of the structure A while the tip end side of the arm 31 supports the hanger frame 2. Bracket B connected to beam A2
On the other hand, the main body portion 33a of the cane portion 32 and the abutting member 33 prevent the tip end side of the arm portion 31 from falling down while supporting the hanger frame 2 from below. A scaffolding body 1 connected to the hanger frame 2
The hanger bracket 3 can be suspended.

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, 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 constituting the body portion of the structure A at the base end thereof. It is assumed that the hook members 34 to be stopped are connected.

The space between the scaffolding body 1 is appropriately connected by a wire rope or the like.
It is possible to further stabilize the disposition state of the construct A on the outside.

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 strut device or the like when it is not used. It will be possible.

[0108]

As described above, according to the present invention, while the scaffold is formed in a rigid structure, the multi-stage scaffold is connected by ladders or stairs so as to be along the pillar portion which constitutes the body portion of the structure. Since it is distributed to the outside, it is of course possible to secure a wide scaffold in which a multi-step scaffold is continuously provided in the longitudinal direction on the outside of the structure, and since the scaffold body is set to have a rigid structure, for example,
Compared with the conventional one, which is formed into a highly flexible structure such as a so-called rope ladder, the required stability can be obtained by providing only a few fixed points against shaking due to wind pressure, etc. There is an advantage that it can be formed.

According to the present invention, the scaffolding body is suspended by the hanger bracket through the hanger frame fixedly connected to the scaffolding body, and the hanger bracket is used as a beam portion or a pillar portion which is a body portion of the structure. Since it is said to be separably connected directly to the beam base material that forms the beam part or to the mounting part that is connected to the beam base material, it can be installed not only before the construction is completed but also until the completion including the middle Therefore, it is possible to use the scaffold at any time for repairing the useless construction, and there are advantages such as improving the progress of the entire construction.

Further, according to the present invention, the continuous position of the hanger frame, which is integrally connected to the scaffold body, with respect to the hanger bracket can be adjusted in the axial direction of the hanger bracket, so that the hanger frame is integrated with the hanger frame. The advantage is that it is possible to select how far away the existing scaffold from the outer wall of the structure.

Further, according to the present invention, since the connecting rod for vertically connecting the vertical ground material constituting the scaffold body has the intermediate portion connected to the frame body constituting the hanger frame under the retaining structure, The hanger frame can be surely integrated with the scaffolding body, and therefore, the scaffolding body can be moved by using, for example, a crane, which is advantageous in that so-called refilling work is simplified and efficiency is improved. is there.

As a result, according to the present invention, it is possible to secure a wide hanging scaffold, and it is possible to carry out normal handling during transportation and storage, and moreover, the skeleton part of the structure can be completed. Even if it exists, it can be used, and it is possible to provide a multi-story suspended scaffold that is most suitable for use when constructing a structure such as a middle-high-rise building.
