Description

[Detailed Description of the Invention] The present invention relates to a wall workbench, and more particularly to a mobile scaffolding device used for construction, painting, etc. of concrete buildings with balconies such as high-rise residences and office buildings.

For buildings with balconies that extend to the outside of the building, such as high-rise residential buildings, office buildings, and school buildings, after concrete is poured for the balconies, painting, pasting of exterior tiles, and installation of metal fittings, etc. are required. BACKGROUND OF THE INVENTION A lot of construction work may have to be carried out, and there have been many requests for simple scaffolding devices that can be used for this purpose.

However, what has been used in the past often uses temporary scaffolding erected from the ground along the outside of a building, and those with a simple structure are rarely used.

In addition, for large buildings such as oil tanks and other objects with large wall areas,
Mobile suspended scaffolding as shown in Publication No. 13275 is sometimes used, but such equipment is not effective for walls that have a very large area to be painted, as mentioned above. However, it is unsuitable for construction where the wall area to be constructed is extremely narrow, such as high-rise houses.

The purpose of the present invention is to provide a mobile scaffolding device that can be easily moved along a building's balcony railing, has a simplified configuration, and can fully perform its function as a scaffolding. do.

The mobile scaffolding device of the present invention includes an upper member for placing a scaffold board, inner and outer members that support the horizontal roller device, and a roller support member that connects the middle of the inner and outer members and supports the vertical rollers. The frame body is formed from a diagonal member that connects the overhanging part of the upper member and the outer member, and clamps provided on the diagonal member and the inner member connect adjacent scaffolding devices and It is designed to construct a long-length mobile scaffolding device.

As members for running or fixing the scaffolding device along the balcony handrail, a vertical roller device, an inner roller device, an outer roller device, and a fixing member are provided. The rollers are in contact with each other along the outer surface, allowing for easy and stable movement.Furthermore, when working on scaffolding, the rollers are placed in contact with each other against the balcony railing. This allows the scaffolding device to be securely fixed.

Next, an embodiment of the present invention will be described based on the drawings. As shown in FIG. Reference numeral 2 denotes an upper horizontal upper member 3, an outer member 5 and an inner member 6 that hang down from one end of the upper member 3 and an intermediate part, and a diagonal member 4 that connects the lower part of the inner member 6 and the other end of the upper member 3. It is composed of.

Further, the roller support member 7 that connects the outer and inner members 5 and 6 at a midway portion thereof is provided so that its inclination matches the upper surface 31 of the handrail 30 of the balcony.

Furthermore, clamps 8a to 8d are provided on the upper and lower outer sides of the diagonal member 4 and on the sides of the outer member, respectively. These clamps have almost the same configuration as those used when connecting temporary construction members, and each of these clamps 8a to 8d fixes and holds the round cable pipe connected to the adjacent frame. A plurality of frames are connected horizontally, and a scaffold board 34 is stretched over the upper member 3 to form a work scaffold.

A vertical roller device 10 is provided on the roller support member 7 described above. As shown in FIG. 2, the vertical roller device 10 has shafts 12, 12 on a roller support 11.
Two vertical rollers 13, 13 are provided via the veranda handrail 30.
It is adapted to roll on the upper surface 31 of.

Furthermore, an inner roller device 15 and an outer roller device 20 are provided on the surfaces of the outer member 5 and the inner member 6 facing the handrail, respectively, so as to face the inner surface 32 and outer surface 33 of the balcony handrail 30.

The inner roller device 15 is shown in FIGS. 1a and 3.
It has the structure shown in the figure, and is provided at two or more locations on the upper and lower sides of the inner member 6 on the side facing the balcony handrail, and supports connected to the inner member 6. 16 is provided with an inner roller 18 via a vertical shaft 17, and the roller 1
8 rolls in contact with the outer wall surface 33 of the handrail 30.

Further, the outer roller device 20 is provided on the side of the outer member 5 facing the handrail 30,
As shown in FIGS. 4a and 4b, it is adapted to roll on the flange of the outer member 5 via a rod 21.

And the rod 21 screwed onto the nut 19
A substantially U-shaped roller support 22 is provided at the end of the roller, and an outer roller 24 is provided via a shaft 23.
By rotating the rod 21, the contact and separation between the outer roller 24 and the inner wall surface 32 of the handrail is adjusted. At this time, as shown in Fig. 4b, the rod 2
1, a projection 22' provided at the bottom of the roller support 22 is rotatably fitted into a recess 21' formed in the circumferential direction of the rod 21.
Even if the rod 21 is rotated, the roller support 22 can be pressed against the balcony 30 without rotating.

Further, a horizontal regulating plate 36 of the outer roller 24 is provided protruding from the outer member 5 to hold the outer roller 24 in a horizontal state, thereby facilitating smooth movement of the scaffolding device.

Next, the fixing member 25 has a pressing plate 27 provided at the end of a rod 26 that is screwed onto a nut 28 and has a screw formed on its outer surface. It is designed to move forward and backward facing the balcony wall.

As shown in FIG. 5, the pressing plate 27 has a projection 27' rotatably fitted into a recess 26' formed on the outer periphery of the tip of the rod 26, so that the rod 26 cannot be rotated. Even if the pressure plate 27 is rotated, the pressure plate 27 can be pressed against the balcony wall surface.

Therefore, since the mobile scaffolding device 1 of the present invention has the above-described configuration, a plurality of scaffolding devices are connected via the clamps 8a to 8d, and the scaffolding board 34 is placed on top of the upper member 3. The mounted state is moved along the balcony 30, and during the movement, the rod 21 is protruded from the outer member 5 so that the roller 24 of the outer roller device 20 comes into contact with the inner wall surface 32 of the balcony 30. let With this configuration, rollers 13, 18, and 24 roll on the inner and outer wall surfaces and the upper surface of the balcony.
These rollers arranged in a substantially U-shape allow for easy horizontal movement.

In addition, during work, the fixing member 25 is protruded and activated, the outer roller device 20 is retracted, and the veranda 30 is moved between the inner roller device 15, the fixing member 25, and the outer roller device 20.
It will be fixed in a clamped state by the vertical roller device 10, and a worker can ride on the scaffolding board 34 and perform painting of the outer wall surface of the upper floor and other works in a stable state. It becomes possible.

In addition, the code|symbol 35 is a connection member of a handrail support (not shown).

In the above-mentioned embodiment, by using rubber wheels as rollers, it is possible to prevent damage to the balcony wall surface, and the scaffolding device can be moved smoothly and easily when traveling along the balcony wall surface. It is possible.

Furthermore, the upper and lower spacing of the roller device can be set arbitrarily, and the attachment point of the fixing member can also be set arbitrarily depending on the overhang length of the scaffold, allowing for freely adjusting its movement and fixing. It makes it possible.

Since the scaffolding device of the present invention has the above-described configuration, it is possible to construct and move the scaffolding very easily when constructing a balcony or painting a building.

In addition, the structure of the scaffolding device is very simple and has sufficient strength, so that workers can work safely by riding on the scaffolding that extends into the air from a balcony or the like. This makes it possible to safely carry out work on the outside of the balcony on the upper floor or on the lower side, that is, on the ceiling of the balcony on the floor where the scaffolding has been set.
