DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scaffold used on the outside of a building under construction, and more particularly to a scaffold which can be easily assembled.

[0002]

2. Description of the Related Art When building buildings such as factories and buildings,
First, a steel frame to be used as pillars and beams is assembled on the foundation to create a building skeleton.A scaffold is assembled around this skeleton, and materials such as wall materials and flooring materials are carried from the scaffold. Is formed.

[0003] A scaffold used for such a purpose is formed by combining standardized pipe materials of various lengths vertically, horizontally and diagonally, connecting the ends with joints, and tightening with bolts and nuts. Frame and each layer of this frame (each step)
And a plate-shaped passage attached to the vehicle. The frame is assembled to a height approximately equal to the height of the building,
There are also stairs connecting the upper and lower passages.

[0004] After the building skeleton is completed, all the materials are brought in from such a scaffold, and the outer wall,
Construction work is performed on the driving parts of the building, such as the inner walls and floors, and various facilities such as various piping such as water and gas, and electric wiring.
Therefore, this scaffold needs to be formed so as to surround the entire building so that necessary materials can be supplied to the entire building.

[0005]

However, assembling the scaffold to the size surrounding the entire building requires a large amount of scaffolding material and assembling work time, and as a result, the cost of the scaffold is extremely high. Would be expensive. In addition, since this scaffold cannot be removed until the building is almost completed, the external construction work at the foot portion where the scaffold is installed cannot be started until the scaffold is removed. In addition, there is an inconvenience that a large material cannot be transported into the building under construction because the scaffold interferes. In order to avoid such inconvenience, a method of providing a frame portion for a passage in the scaffold has been devised. Furthermore, it was also difficult to check the progress of the finish from the outside. Conventional mobile scaffolds, such as rolling towers, lack stability and are difficult to use as long working platforms that cover the side walls of buildings.

The present invention has been conceived in view of the above facts, and has as its object to provide a scaffold that can be assembled at low cost and that allows a user to easily visually check the progress of the finish.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a frame assembled substantially vertically, and one or more layers (steps) formed substantially horizontally in the frame. A passage, a truck attached to the lower end of the frame , and
A plurality of mounted wheels and rails on which the wheels travel
A mobile scaffolding hand comprising:
The width of the rail is larger than three
The upper and lower trolleys where the above trolleys overlap vertically
By adjusting the length of these overlapping parts,
Is configured to be changeable .

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing the entire mobile scaffold of the present invention. In the drawing, A indicates a building under construction.
The frame 1 is assembled on site and has a length L smaller than that of the conventional one, and a length covering a part of one side of the building A, but other basic configurations are the same as those of the conventional scaffold. .
In other words, standardized pipe materials of various lengths are
They are arranged sideways, diagonally, etc., and are formed by connecting the connecting parts with fastening hardware or the like and tightening them with bolts or nuts, and have the same width w at the top and bottom.

A work passage 2 is formed in the frame 1. The position of the work passage does not always match the height of the floor of the building A. Passage 2 of each layer (each step)
Are used as scaffolds for interior and exterior work, and at the same time used as a path for workers to carry materials or as a back and forth path. Therefore, a plate material is used for the passage 2 to make it easy to walk. Moreover, as shown in the figure, stairs 8 are provided at appropriate places to connect the passages 2 of each layer (each step) and to easily move up and down each layer (each step).

The lower end of the frame 1 is supported by a plurality of carts 3. A plurality of wheels 4 are attached to the lower surface of each truck 3, and each wheel 4 fits into a concave groove provided on the rail 5 so that it can run on the rail. The wheel is made of a hard petit stick such as urethane, is formed to have a width substantially equal to or slightly smaller than a width of a groove provided in the rail, and is configured to run in the groove of the rail. Rail 5
The length can be set to an appropriate length, but is preferably a length that can be carried and relocated. The rails can be relocated and extended, and are moved and installed along the length of one side of the building so that the mobile scaffold can be moved to cover the entire length of one side of the building A.

The width W of the carriage 3 is wider than the width w of the frame, and in the illustrated embodiment, W is about twice as large as w. A diagonal member (or a staff) 6 connects the end of the carriage 3 that is separated from the frame 1 and the side surface of the frame 2. With the above configuration, even when the height of the frame 1 is increased, it is possible to form a scaffold stably without increasing the width of the frame itself. Further, it is desirable that the frame body 1 has a configuration in which the upper part is locked to the building A. However, the frame body 1 can be slid when moving, or can be easily attached and detached, and can be easily attached after moving. It is desirable to have a configuration.

Since the movable scaffold of the present invention has the above-described configuration, construction work can be performed while moving along the rails. Therefore, a size for covering the entire building is not required, and a frame having a reduced length L is sufficient. Also, not only outside the building, but also inside construction can be performed. When carrying materials into the building under construction, moving the scaffold from the entrance makes it easy to carry the material.In addition, drainage troughs and plumbing facilities that were conventionally constructed after removing the scaffold Also, ancillary work such as pavement and exterior construction work can be performed simultaneously with interior and exterior work of the building. If you want to see the appearance during construction, you can check it by moving the movable scaffold. Since the scaffold runs on the rail 5, the scaffold can be moved lightly, and even a scaffold having a height of eight layers (steps) can be moved by about two workers. Of course, it is also possible to retreat freely. In order to fix the scaffold at a desired position, a wedge or the like may be bitten on the wheel 4, but a wheel stop device may be provided on the wheel 4. In addition, a motor for driving wheels can be provided on the cart to facilitate movement. In addition, since one wall of the building can be sequentially finished from the end, the work immediately below the scaffold can be performed from the end, and the scaffold can be removed efficiently.

The rail 5 is generally constructed by arranging three rails in parallel, arranging a plurality of pillows 51 horizontally at fixed intervals, and fastening the whole with bolts and nuts. One rail, which is composed of three rails crossed by a sleeper, is configured to have a length that can be easily moved by a manual operation of an operator. In this embodiment, the length is 5.5 m.
Has become the length. However, this length is not limited to this. The shape of the surface of the rail 5 is such that the center of the rail is formed as a concave groove for running the wheel so that the wheel can fit on the rail without running off the rail. The fastening connection between the rails is performed by connecting the connecting portions with bolts or the like.

[0016]

FIG. 2 shows the bogie and rails of FIG . Cart 3 or two second carriage 3b of the upper and carriage 3a of the lower minute
Have been. The lower trolley 3a has substantially the same width as the frame 1, and the upper trolley 3b has wheels 5 provided on only one side.
Its width is larger than the width of the carriage 3.

Further, connecting portions 8a, 8b, 8c... Are formed at a plurality of positions on the beam in the depth direction of the upper bogie 3b, and a pair of connecting portions 9 are formed on the beam of the lower bogie 3a. Is provided. An end of the upper bogie 3b without wheels is mounted on the lower bogie 3a, and both bogies are connected. Any of the connecting portions 8a, 8b, 8c... And the lower bogie 3
As shown in FIGS. 2A, 2B, and 2C, the width W of the bogie depends on whether the connecting portion 9 of FIG. 2A is connected to the connecting portion 9 as shown in FIGS. 2A, 2B, and 2C. Can be changed, and the width of the carriage can be changed to Wa, Wb, Wc.

In this case, the lower cart 3a and the upper cart 3b may be manufactured by standardizing one type at a time.
If the building has a height of, for example, 5 to 6 layers (steps), FIG.
Upper and lower trolleys such as width Wa of (a), width Wb of (b) for the height of 7 layers (stages), and width Wc of (c) for the height of 8 layers (stages). It is possible to change the width of the carriage 3 in various ways by adjusting the length of the overlap.

In the embodiment shown in FIGS. 2A to 2C, one of the beams of the upper bogie 3b is placed on the lower bogie 3a, but as shown in FIG. The beam 32 in the depth direction of 3a may be formed of a hollow square pipe, and the beam 34 of the upper carriage 3b may be fitted into the hollow beam and connected at an appropriate location. As connecting portions, through holes for connecting are formed at appropriate places in the square pipe beam 32 of the lower bogie 3a and the fitting beam 34 of the upper bogie, and the connecting holes are aligned after fitting the beams. It is a configuration in which a pin or a bolt and a nut are penetrated and fastened at a communicating place. The number of coupling holes formed in the beam and the setting of the respective intervals are not limited to those of the embodiment.

[0023]

Even in a work site having a step on the floor of a construction site, such as a roof of a stand of various stadiums, a relatively horizontal upper part can be obtained by laying a rail on each of the steps having a step. A wide movable scaffold can be formed, and can be moved in parallel on the rail as it is. Further, the height of the upper end of the movable scaffold can be changed as appropriate, and can be partially changed. In other words, if you make a scaffolding shape along the curve of the roof in only one place, the mobile trolley will move in parallel on the rail along the roof while keeping its shape, so for roofs of the same shape (curve) It is possible to work efficiently.

[0025]

As described above, the movable scaffold of the present invention comprises a substantially vertically assembled frame, and one or two or more layers (steps) formed substantially horizontally in the frame. When,

Can be. Because of the above-described configuration, types of carts are limited, but carts of various widths can be obtained.

[0026]

Since the above-mentioned rail is of a length that can be carried and relocated, it is extremely easy to lay and remove the rail, and it is not necessary to lay the rail all the length of the building at all times. You can avoid getting in the way.
Since the frame of the movable scaffold moves along one side of the building to cover the entire side while moving, the small scaffold can cover the entire building, and the scaffold can be created at low cost. In addition to being able to move the scaffold, it will be possible to carry materials into the building under construction. In addition, drainage troughs, plumbing equipment, ancillary work such as pavement, external construction work, flower bed installation, etc., which had been done after removing the scaffold, can be done simultaneously with the interior and exterior work of the building body Therefore, the construction period can be significantly reduced. In addition, when the user wants to see the external appearance during construction, the user can visually check by moving the movable scaffold.
