Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a workbench used for finishing work on the rising portion of a building such as a handrail, and in particular, it is an optimum workbench for a handrail of an apartment or school building. Regarding

(Prior Art) Recently, high-rise houses and the like have been actively built, and they have become increasingly high-rise and multi-layered. When constructing such high-rise houses (condominiums, apartments, school buildings, etc.),
After pouring concrete on the handrails such as the balcony and balcony, it is necessary to perform work such as external finishing and caulking.

In this case, conventionally, a scaffold has been assembled from the ground to secure a safe work place for these works. However, this scaffold assembly work requires a lot of materials and labor because it is a high-rise building, which has been an obstacle to the construction of high-rise houses. Therefore, in order to solve this, Japanese Utility Model Publication No. 58-41853 and Japanese Utility Model Publication No. 62-151343.
A workbench as described in Japanese Patent Publication has been proposed.

All of these worktables are suspended and held on the top surface of the rising part (concrete handrail wall) of the building by the locking part of the inverted L-shaped frame extending from the upper end of the inner pillar of the workbench, and The horizontal and vertical parts forming the engaging part and casters mounted above and below the inner column are configured to instruct the rising part to abut. Therefore, the worker rides on the workbench to perform the required finishing work, and the position of the workbench after the work is finished is laterally moved by the caster while moving the workbench along the rising portion.

(Problems to be solved by the invention) However, these conventional worktables only hold the top of the rising part (concrete handrail wall) at the upper end of the workbench, and the caster is attached to the wall at the lower end. Since the structure is such that it only abuts, it is indicated at one place for downward load, but for external force acting on the lower end in the outward direction (the direction opposite to the concrete handrail wall support direction). Is extremely unstable. Further, since all the downward load acting on the workbench is concentrated on the inverted L-shaped frame (engagement part) extended to the upper part of the workbench, this part needs to be made of a member having sufficient strength. On the other hand, the strength of the top of the concrete handrail wall must be able to withstand this.

Furthermore, since the casters provided on the inner pillars of the work table move while rubbing the concrete handrail wall surface, the wall surface may be damaged. If the workbench with such a structure is a metal handrail (a handrail in which the top rail is composed of pipes and the pipes are supported by stanchions arranged at regular intervals), and there is no caster contact part It is not suitable because there are also Furthermore, when a worker transfers from the balcony or the like to the work table, it is necessary to get over the top of the concrete handrail wall and go down from the work table to the lower scaffolding. Become. In particular, in the high-rise part, the psychological instability becomes unstable and the risk of a fall increases. A similar danger is involved when the worker gets off the work table after the work is completed.

Therefore, an object of the present invention is to provide a safer workbench by eliminating the disadvantages of the conventional workbench described above.

(Means for Solving Problems) Therefore, the feature of the solving means according to the present invention is that the main frame of the workbench is a pair of front and rear outer pillars, inner pillars, and cross members that are laid across between the outer pillars and the inner pillars. Formed in, the extension member is continuously provided on the outer pillar,
An upper engaging member that engages with the handrail pipe of the upper floor is provided at the upper end of the extending member, and a lower engaging member that engages with the handrail pipe of the lower floor is provided at the lower portion of the inner pillar, and the handrails of the upper and lower floors are provided. Is configured to support the work table.

(Operation) In the present invention configured as described above, since the engaging members are provided on the upper and lower sides of the workbench, the workbench is provided on the upper and lower handrails 2.
Can be held in place. Therefore, the lower load applied to the workbench is supported at two upper and lower positions, and the workbench can be held more stably. In addition, when transferring to the work scaffold, the scaffold itself is formed to be approximately flush with the top of the handrail, and since the safety fence is formed on this scaffold with outer pillars, inner pillars, etc., the worker can climb over the handrail. You can easily transfer to the workbench.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

1 and 2 show a workbench according to the present invention, FIG. 1 is a side view thereof, and FIG. 2 is a view taken along the line I--I in FIG.

In FIG. 1 and FIG. 2, the main frame of the workbench is a pair of front and rear outer columns 5, 5, inner columns 9, 9 and cross members 6, 7, 8 which are laterally bridged between the outer columns 5, 5. Is formed by. The inner pillar 9,
The upper portion of 9 is obliquely bent and fixed to the upper portions of the outer columns 5 and 5. In addition, the side members 7 a and 8 a are laterally bridged between the outer column 5 and the inner column 9. The rectangular frame of the scaffold 10 formed at the lower end is composed of bottom members 11, 12. The scaffold 10 is formed of a checkered plate or a grating or the like.

A safety net is stretched on the side surface and the back surface of the workbench 1. The safety net is on the top (between the cross members 6-8 and on the upper side)
Is formed by a wire mesh with a relatively large mesh, and the lower part (cross member 8
A space between the bottom members 11 and between the side members 8b and the bottom member 12 is provided with a fine mesh wire mesh to prevent the work tools from falling.

Extension members 15, 15 having two bending points are provided at the upper ends of the outer columns 5, 5 with a height adjusting member 14 interposed therebetween. The extending members 15, 15 may be formed in an arc shape. At the ends (upper ends) of the extending members 15 and 15, engaging bodies 16 and 16 that engage with the handrail pipe 4 forming the handrail 3.
Is provided. Moreover, similar engaging bodies 17, 17 are attached to the lower ends of the inner columns 9, 9. Therefore, the workbench 1 is engaged and supported by the upper and lower handrail pipes 4 by the upper and lower engaging bodies 16 and 17.

Lateral members 18 and 19 are laterally provided between the extending members 15 and 15 to fix the interval between the extending members 15 and 15 and to make the framework rigid. The height adjusting member 14 has a male screw, the lower end of which is screwed to the upper end of the outer column 5 and the upper end of which is screwed to the lower end of the extending member 15, respectively.
It is fixed at b. The height of the extending member 15 is the adjusting rod 14
It can be adjusted by turning a in a desired direction. This allows the workbench 1 to be installed even if the spacing between the upper and lower handrail pipes 4, 4 is slightly different.

The outer pillars 5, 5, the inner pillars 9, 9, the lateral members 6, 7, 8, the side members 7
a, 8a, bottom members 11, 12, extension member 15, lateral member 1
8 and 19 are made of pipe material such as steel pipe, and the workbench 1 has a simple and lightweight structure as a whole. Therefore, it is easy to carry and move, and even when it is installed on the handrail pipe 4, the labor is small.

FIG. 3 is an enlarged view showing details of the engaging bodies 16 to 17. FIG. 4 is a view taken along the line II-II of FIG.

A pair of front and rear vertical pieces 20 and 21 are provided in parallel with each other so as to face each other, and are joined by a horizontal piece 22 at the upper part. The extension member 15 (the bottom member 12 in the case of the engaging body 17) extends on the upper surface of the horizontal piece 22 and is fixed to the chevron portion 20a on the upper portion of the vertical piece 20. On the other hand, a pair of front and rear vertical shafts 24, 24 that penetrate the horizontal piece 22 and the horizontal bent portion 20b at the lower end of the vertical piece 20 are provided (see FIG. 4). The upper ends of the vertical shafts 24, 24 are formed into a brim shape 24a so as to be locked to the horizontal piece 22, and the lower ends thereof are fixed by a double nut 24b, and a disengagement preventing pin 24c is provided. And this vertical axis 24,2
4, a vertical roller 27 is rotatably provided. Similarly, the other vertical piece 21 also has a pair of front and rear vertical shafts 25, 2.
5 is provided with a rotatable vertical roller 28. Further, a horizontal shaft 26 is provided at the center of the vertical pieces 20 and 21, cushioning materials 29a and 29a are provided on both sides, and a horizontal roller 29 is rotatably provided between them.

When the workbench 1 is installed, the handrail pipe 4 is between the vertical rollers 27 and 28, and the upper surface of the handrail pipe 4 contacts the horizontal roller 29. These rollers function as guide rollers when changing the work position of the workbench 1, and facilitate the movement thereof. The vertical rollers 27, 28 are preferably made of plastic so as not to damage the surface of the handrail pipe 4. Further, since the horizontal roller 29 comes into contact with the handrail pipe 4 to support the workbench 1, it is preferable that the horizontal roller 29 is formed of a steel roller having sufficient rigidity.

As is clear from the above description, when the workbench 1 is in use, the upper and lower engaging members 16 and 17 are engaged and supported (supported at two positions) on the upper and lower handrail pipes 4 and 4.

Next, a method of installing and using the workbench 1 will be described.

First, a worker on the upper floor uses a rope or the like to lift the workbench 1 along the handrail 3. And a little balcony 2
It is pulled in and a little lifted so that the engagement bodies 16 and 17 come to a position above the handrail pipe 4. At this time, since the upper part of the inner pillar 9 is bent obliquely, it does not hit the lower surface of the tip of the balcony on the upper floor. Then, a worker on the lower floor positions the lower engaging body 17 on the handrail pipe 4, and at the same time lowers the workbench 1 downward, thereby lowering the upper and lower engaging bodies 16, 1.
7 is engaged with the handrail pipes 4, 4. For lateral positioning, for example, the inner pillar 9 may be moved in the left-right direction. Since the upper and lower engaging bodies 16 and 17 are provided with the horizontal roller 29, they can be moved smoothly. When the workbench 1 is installed, the adjustment rod 14a of the height adjusting member 14 is adjusted in advance so as to correspond to the interval between the handrail pipes 4 and 4 on the upper and lower floors. After setting in the above manner, the worker on the lower floor grabs the inner pillar 9 and transfers to the scaffolding 10 located substantially on the same plane as the handrail pipe 4. In this case, since the safety nets 5a and 5b are stretched on the back surface (outer side) and the side surfaces of the workbench 1, there is no risk of a fall, and it is possible to transfer safely. And
The worker rides on the scaffolding and performs finishing work such as painting of the rising part of the veranda 2 on the upper floor and the handrail. If the handrail 3 is a concrete wall, it is necessary to finish the rising part that constitutes the handrail, but a podable scaffold is installed in the middle tier (for example, although not shown, the level of the cross member 7 is hinged type). A scaffold may be provided on a part of the outer columns 5 and 5), and the work may be performed by riding on this. When working further upstairs,
The workbench 1 may be set in the same manner as above.

(Effect of the Invention) As described above, according to the present invention, since the workbench is held by the handrails on the upper and lower floors, the lower load applied to the workbench is supported at two places, and the workbench is supported. It can be held more stably. Further, by supporting at two points, the load is not concentratedly applied only to the upper engaging body, and thus the structure of the engaging body can be simplified and lightened.

Furthermore, when raising and lowering the workbench, the scaffolding itself is formed substantially flush with the top of the handrail pipe, and the inner and outer pillars standing on the scaffolding serve as safety fences. The workbench can be lifted up and down by overcoming.

Further, the workbench of the present invention can be used not only for a metal handrail type but also for a concrete wall type handrail, and is highly versatile.
