DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for suspending a fixing suspending member and a suspending wire from a structure such as a roof steel frame.
A required number of terrain-based self-climbing suspended scaffolding units are lifted to a predetermined height by the lifting wire, connected to the fixing suspending member, and the self-climbing suspended scaffolding units are connected to each other to construct a suspended scaffold. The present invention relates to a self-climbing suspended scaffold unit used in a large-scale suspended scaffold construction system.

2. Description of the Related Art In general, using a suspended scaffold as a work scaffold in a roof / ceiling construction of a building having a large space such as an atrium, a gymnasium, a theater or the like involves assembling a frame scaffold for ceiling work on a floor surface. There are many advantages compared to the case. For example, when assembling a framework scaffold for ceiling work on the floor surface, the framework scaffold interferes, so that work inside the lower part cannot be performed, and work cannot be started unless ceiling work is completed. There is. In addition, when renovating or repairing the ceiling of an existing building, assembling a scaffold for ceiling work on the floor surface may significantly damage the finishing material on the floor surface. According to the suspended scaffold, it is possible to avoid these inconveniences.

[0003] However, in the case of a conventional general hanging scaffold assembled with a single pipe or the like, in assembling and disassembling, there are many dangerous works at high places and workability is poor. It was troublesome, and it was difficult to shorten the work period for assembling and dismantling the hanging scaffold.

Further, as disclosed in Japanese Patent Application Laid-Open No. 4-228772, a movable steel frame is used to construct a roof steel frame. On the scaffold, a wire for suspending the scaffold suspended from the roof steel frame and a suspending rail suspended by the wire are carried in, and the suspending rail is engaged with the work floor of the movable steel framed scaffold. A method has also been proposed in which a traveling wheel is attached and a work floor of a movable steel framed scaffold is used as a component of a suspended scaffold.

[0005] According to this conventional example, a mobile steel framed scaffold is used for the construction work of the hanging scaffold, so that dangerous work at high places can be reduced. However, since the mobile steel framed scaffold is required, the existing steel framed scaffold is required. It is unsuitable for the renovation and repair work on the ceiling of a building, and has the same problems as when assembling a frame scaffold on the floor.

The hanging scaffold construction system for large spaces described at the beginning has been developed to solve these problems at once, and has the following advantages.

[0007] A fixing hanging member and a lifting wire are hung from a structure such as a roof steel frame, and a required number of self-climbing hanging scaffold units that have been ground are lifted to a predetermined height by the lifting wire. In addition to connecting to the members, the self-climbing suspended scaffolding units are connected to each other to construct a large suspended scaffold corresponding to a large space, so that dangerous work in high places when assembling and dismantling the suspended scaffold can be significantly reduced, and , The suspended scaffolding unit is grounded, so that the suspended scaffolding unit itself can be assembled easily and safely, and the loading and unloading of scaffolding members to high places is reduced, shortening the time required for assembling and disassembling the scaffolding. it can.

[0008] As a lifting device for lifting the suspended scaffolding unit with the lifting wire, an endless winch capable of winding the lifting wire is used.
Since this is a self-climbing system that is detachably provided on the hanging scaffold unit itself, it is smaller than when lifting a large hanging scaffold corresponding to a large space by a lifting device installed on a structure such as a roof steel frame. It is possible to reduce the space and reinforcement for installing a lifting device in a building, and to change the lifting device (endless winch) by changing the lifting device (endless winch). The number of winches used can be reduced.

[0009] In order to construct a suspended scaffold without using a movable steel framed scaffold, the suspended scaffold can be used as much as possible without damaging floor finishing materials even when renovating or repairing ceilings of existing buildings. Can be erected.

[0010]

However, in the above-described hanging scaffold construction system for large spaces, the shape of the self-climbing hanging scaffold unit to be used is planar, and only a flat work floor can be constructed. It was unsuitable for the construction of ceilings with differences and gradients.

Further, even in a building having a horizontal ceiling, a fireproof covering work on a roof steel beam or a steel beam, a piping work for equipment behind the ceiling, a work for mounting a ceiling panel, and a work for mounting a lighting fixture are required.
Since the work is performed from above in this order and the height is changed little by little (for example, about several tens of centimeters), the level of the work floor required in each work is slightly different. With a flat-shaped self-climbing suspended scaffolding unit, it is necessary to gradually change the height of the suspended scaffolding unit as the work progresses. Many operations such as replacement, disconnection and reconnection of the fixing suspending member, and the like, were not possible, and quick response was impossible.

The present invention solves these problems while securing the above-mentioned advantages in a large-space suspension scaffolding construction system. The object of the present invention is to construct a ceiling with a difference in elevation or a slope. To provide a self-climbing suspended scaffolding unit capable of quickly and safely constructing a work floor.

[0013]

In order to solve the above-mentioned problems, according to the present invention, a hanging member for fixing and a wire for lifting are suspended from a structure such as a roof steel frame, and self-climbing of a required number of grounds is carried out. The large-scale suspension scaffold construction in which the suspension scaffold unit is lifted to a predetermined height by the lifting wire and connected to the fixing suspension member, and the self-climbing suspension scaffold units are connected to each other to construct a suspension scaffold. In configuring a self-climbing suspension scaffold unit used in the system, an endless winch capable of winding the lifting wire is detachably attached, and a plurality of sheets are provided on a main frame provided with a connecting portion to the fixing suspension member. Is characterized by being laid in a plurality of levels and in a detachable state. The vertical interval between the floor materials is set to, for example, several tens of centimeters.

According to the above configuration, the lifting wire hanging from the roof steel frame or the like can be wound around the endless winch to drive the self-climbing suspended scaffold unit up and down.

Since the endless winch is detachably attached to the main frame of the self-climbing suspended scaffolding unit, the self-climbing suspended scaffolding unit is raised to a predetermined height, and the main frame is suspended from a structure such as a roof steel frame. After being connected to the fixing suspension member and fixed to the structure, only the endless winch is lowered and can be diverted as a lifting device for the next self-climbing suspended scaffolding unit. In this case, it is necessary to suspend another lifting wire at a predetermined position on the structure or to change the mounting position of the wire, but in any case, the wire itself is relatively lightweight, Is easy,
There is no need to secure a large space for installing the lifting device in a structure such as a roof steel frame, and no reinforcing structure for installing the lifting device is required.

Then, the required number of self-climbing suspended scaffolding units suspended at a predetermined height are connected to each other by a steel material or the like to construct a large suspended scaffold corresponding to a large space.

Therefore, the above-mentioned advantages (1) to (4) can be obtained. In addition, the main frame is provided with a plurality of flooring materials, for example, at a vertical interval of several tens of centimeters, in a plurality of steps, and
Because it is laid in a removable state, for example, in each self-climbing suspended scaffolding unit, at one end,
The flooring is made up of one step, and the number of steps is increased to two steps and three steps as it goes to the other end, thereby constructing a stepped work floor with a vertical interval of, for example, several tens of centimeters. Thereby, the entire work floor can be made substantially along the slope of the ceiling.

In a building having a horizontal roof steel frame,
When performing the fireproof covering work on the roof steel frame, the piping work of the equipment above the ceiling, the work of installing the ceiling panel, and the work of installing the lighting equipment, in this order from the top and by gradually changing the height, for example, several tens of centimeters in advance As the work progresses, the floor materials laid in multiple levels at intervals of
By stepwise removal, the level of the work floor required for each operation can be quickly and safely realized.

Each self-climbing suspended scaffolding unit A
As shown in FIGS. 2 to 4, a horizontal member mounting portion 12 made of a circular flange-shaped metal member having small holes 11 for driving a wedge 10 formed at regular intervals in a circumferential direction has a height of about 30 cm in the vertical direction. A plurality of pillars 13 at four corners provided at a plurality of meter pitches, a steel truss frame 14 laid on the pillars 13 and, if necessary, side brackets connected to at least one side of the steel truss frame 14. Fifteen
(It has a horizontal pipe 15a having a telescopic double pipe structure so that the amount of protrusion from the steel truss frame 14 can be adjusted.) A stud 16 similar to the pillar 13, and a handrail pipe 1 spanning the pillar 13 and the stud 16.
7 and the like, and a main frame 18
A plurality of stages (in the illustrated example, two stages with a vertical interval of about 90 cm) are provided at a vertical interval of about 30 to 90 cm via a horizontal pipe 19 laid on the horizontal member mounting portion 12. Moreover, it includes a plurality of rectangular steel floor members 20 laid in a detachable state.

Four pillars 13 (steel truss frames 14)
The endless winch 5 into which the lifting wire 1 can be wound is detachably attached to each of the column members connected to the column member by a clamp hardware and bolts and nuts for tightening the same. At the upper end of each of the fixing members 13, a connecting portion 21 for the fixing hanging member 2 is provided.

As the connecting portion 21, various specific configurations can be adopted. In this embodiment, as shown in FIG. 4, a bracket 22 having a horizontal pin hole is laid at the upper end of the column member 13. Thus, the connecting portion 21 is configured. Then, a buckle 23 is attached to the bracket 22 with a pin 24.
And the upper end of the buckle 23 is connected to a shackle 25 provided at the lower end of the fixing hanging member 2 by a pin 26 which can be inserted and withdrawn. The connection of the components in the main frame 18 is performed by a wedge 10 or a pin (not shown) penetrating the double pipe portion of the pipe.

The floor member 20 may be laid in a plurality of steps over the entire area of the main frame 18, or may be partially laid in a plurality of steps. In the latter case, the height of the upper and lower working floors is 3
If it is about 0 cm, there is no problem in climbing and descending, so it is not necessary. However, if it is a step of about 60 to 90 cm, as shown in FIG.
It is desirable to lay a slope-like or step-like flooring material 20a over the floor to make it easy to ascend and descend to each step. The level difference between the upper and lower working floors (the vertical interval between the floor members 20) can be set arbitrarily in accordance with the pitch (the vertical interval) between the horizontal member mounting portions 12 provided on the column members 13. In consideration of the vertical width of the ducts suspended in the ceiling, the mounting level of the ceiling plate, and the like, the pitch of the horizontal member mounting portion 12 is set to about 30 cm, as in the above-described embodiment, and the step ( The vertical spacing of the flooring material 20 is set in the range of about 30 to 90 cm, or the pitch of the horizontal member mounting portion 12 is set to about 20 cm, and the height difference between the upper and lower working floors (the vertical spacing of the flooring material 20). ) Is set in the range of about 20 to 100 cm.

The hanging scaffold B is, as shown in FIG.
On the first floor (cured by plywood, sheets, etc.) F, self-climbing suspended scaffolding units A are laid, and the required number of self-climbing suspended scaffolding units A are formed.
Are lifted to a predetermined height by remote control, and they are connected to the fixing hanging member 2 to be fixed to the structural body 3, and the self-climbing hanging scaffold units A are connected to each other by the steel material 7 or the like.

After the self-climbing suspension scaffolding unit A is fixed, the endless winch 5 is separated from the main frame 18 and remote-controlled on the operation panel 4 so that only the endless winches 5 are simultaneously or one by one to the first floor F. After being lowered, it is diverted as a lifting device for the next self-climbing suspended scaffolding unit A.

According to the above configuration, for example, as shown in FIG. 5, even in a building with a horizontal ceiling, fireproof coating work on a roof steel frame or a beam steel frame, and installation of equipment piping (air conditioning duct, etc.) 27 behind the ceiling are performed. When the work, the installation work of the ceiling plate 28, and the work of installing the lighting equipment are performed in this order from above and with the height being changed little by little, the work is laid in advance in a plurality of steps at vertical intervals of several tens of centimeters. By removing the floor material 20 one by one from the upper ones as the work proceeds, the work floor levels F ₁ and F ₂ required for various works can be realized quickly and safely.

If the floor material 20 is laid only one step, and if the floor material 20 is to be rearranged sequentially to a lower position, when the floor material 20 is temporarily removed, the work is partially performed. It is very difficult to ensure safety because a state where the floor does not exist is caused. However, according to the above configuration of the present invention, it is necessary to remove the floor material 20 laid in a plurality of stages from the upper one in advance. By adjusting the level of the work floor,
In a state where the floor material 20 exists in the lower stage, the level of the work floor is adjusted, and safety is ensured.

As shown in FIG. 6, when the roof steel frame has a slope, each self-climbing suspended scaffolding unit A
In, in one end, the flooring 20 as a first stage, to the other end, in two stages, or more to increase the number of stages, by laying, stage floor like working floor (level F ₁ to F ₄ )
Is constructed, so that the entire work floor can be substantially along the slope of the ceiling. Reference numeral 29 shown in FIG. 6 is a framework scaffold assembled near the wall, and forms a boarding path 30 to the hanging scaffold B.
