Abstract

PURPOSE:To uniform a construction quality by hanging a work scaffolding from the upper part of a building in such a way that the scaffolding can easily go up and down along the wall surface of a building, and surrounding the work space of the scaffolding in the weather resistant state, as well as regulating the atmosphere in the work space by an air conditioner. CONSTITUTION:A supporting beam 10 with the tip thereof protruding from the wall surface of a building 1 is provided on the roof part of the building 1, and a work space A is formed on a suspended scaffolding 30 hung through hanging wire ropes 20. The space A is surrounded with a water barrier sheet 40, and the atmosphere in the space A is regulated by an air conditioner fitted on the scaffolding 30. The space A is thus surrounded in the weather resistant state, and the air temperature and humidity are regulated by the air conditioner. Construction of uniform quality can be thereby performed regardless of the weather.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a work scaffold used for construction work.

(Prior Art) Since the outer wall surface of a building is constantly exposed to the external environment, it is easily contaminated by the effects of wind, rain, heat, etc.

Therefore, it is necessary to regularly clean and repair the exterior wall surface, and when performing these tasks, scaffolding for repair work is erected around the outer periphery of the building.

As conventional general work scaffolding, main scaffolding, frame scaffolding, gondola scaffolding, etc. are known. This scaffolding or framework scaffolding is constructed from the ground to surround the entire building. In addition, gondola scaffolding suspends a gondola that serves as a work floor from the roof of a building, and moves it as the work area moves.

Since the main purpose of these work scaffolds is to provide scaffolding for wall construction work, the work environment can be said to remain mostly outdoors.

By the way, a so-called protective net is sometimes installed around the outer periphery of a work scaffold, but this is for safety and hygiene measures to prevent tools from falling and paint from scattering, and is especially used to protect against rain, snow, and sunlight. It is not established to prevent such things.

By the way, construction materials such as paints and sealants used in construction work cannot be used in a good manner no matter what the environment, and manufacturers usually set recommended conditions for good construction.

However, as mentioned above, the work environment on these work scaffolds is similar to being outdoors, so the temperature and humidity at the time of construction change depending on the weather. For this reason, even for a single building, the finish may vary depending on the weather, making it difficult to maintain uniform quality. Additionally, in cold regions, construction may be difficult during the winter when temperatures are low.

In addition, rain, snow, etc. sometimes interfere with the work, which can cause the process to go awry.

(Problem to be solved by the invention) As described above, since the construction conditions of conventional work scaffolding are affected by the weather, it is difficult to uniformly control the construction quality, and work cannot be performed depending on the weather. There was also a problem.

The present invention was made to solve such problems,
The aim is to provide work scaffolding that can perform construction of uniform quality regardless of the weather.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above-mentioned purpose, the work scaffold of the present invention suspends a suspended scaffold that can be raised and lowered from the top of the building along the wall of the building. This work scaffold is characterized in that the work space of the suspended scaffold is weatherproofed and the environment within the work space is adjusted by an air conditioner.

(Function) The work scaffold of the present invention weatherproofly encloses the work space on the suspended scaffold that is suspended from the top of the building so that it can be raised and lowered, and the environment within this work space is adjusted by an air conditioner. It becomes possible to maintain conditions within the work space suitable for construction, and uniform construction quality can be achieved.

In addition, since rain, snow, wind, etc. are blocked, work can be carried out regardless of the weather.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view for explaining the structure of a working scaffold according to an embodiment of the present invention, and FIG. 2 is a perspective view showing the entire working scaffold of FIG. 1.

As shown in these figures, the work scaffold of this embodiment is suspended from a plurality of support beams 10 attached so that their tips protrude from the wall surface of the building 1 on the roof of the building 1 via hanging wire lobes 20. A work space A above a hanging scaffold 30 is surrounded by a water-blocking heat insulating sheet 40, and the environment of this work space A is adjusted by an air conditioner 50 mounted on the suspended scaffold 30.

Each of the above-mentioned support beams 10 is temporarily fixed to, for example, a rosette provided on the roof of the building 1 at substantially equal intervals. Two hanging wire lobes 20 are tied to each support beam 10, and the lower ends of each hanging wire lobes 20 are tied to the frame 31 of the hanging scaffold 30 via hoists 32 and 33, respectively. . In addition, all the hoisting machines 32.33 provided on the suspended scaffolding 30 are interlocked, and these hoisting machines 32.3
3 is operated by a worker on a suspended scaffold 30. The hanging scaffold 30 is designed to move up and down along the wall surface of the building 1 while maintaining a generally horizontal state as a whole.

In addition, this hanging scaffold 30 is surrounded by a frame 34 made of metal pipes, etc., including the ceiling part, except for the side of the building 1, and the outside of this frame 34 is covered with a heat-insulating sheet that has water-blocking properties.
40 is covered. This prevents falling from the hanging scaffold 30, serves during rain or snow, and provides insulation between the work space A and the outdoor environment. Furthermore, this hanging scaffold 30
Guide rollers 36 are attached to the pedestal 31 for smoothly raising and lowering the scaffold 30 along the wall surface of the building 1.

Now, the feature of the work scaffold of this embodiment is that, as described above, the work space A on the suspended scaffold 30 is surrounded by a water-blocking heat insulating sheet 40, and the air conditioner 50 adjusts the temperature and humidity.

This makes it possible to perform construction under optimal construction conditions regardless of the weather or climate.

Here, a heat insulating sheet with water-blocking properties was used as the sheet surrounding the work space A, but the construction conditions could be further improved by providing this sheet with the property of blocking ultraviolet rays or solar radiation.

In addition, in the above-mentioned embodiment, a frame 34 is provided around the work space A.
The work space A is weather-proofed by covering the outside of this frame 34 with a heat insulating sheet 40, but the present invention is not limited to this, and the work space A is surrounded by a resin panel or the like. Space A may be surrounded, and F RP (Fi
ber Re1nforced PlaStlC,S
; fiber-reinforced plastic) may be used to form a box-shaped suspended scaffold with an opening only on the surface that contacts the wall. Also,
Although this embodiment has been described using a single-tier suspended scaffolding in which the building is divided horizontally, it is of course possible to use a suspended scaffolding in which the building is divided vertically or in two tiers.

Furthermore, in the present embodiment described above, the air conditioner 50 for adjusting the environment in the work space A is installed on the hanging scaffold 30, but the air conditioner 50 installed on the ground or on the roof of the building can be connected to the The work space A may be air-conditioned.

[Effects of the Invention] As explained above, according to the work scaffold of the present invention, construction can be performed with uniform quality regardless of the weather.
