Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of the present invention, in which reference numeral 1 indicates a temporary enclosure structure. The temporary enclosure structure 1 is used around the construction site to partition the construction site from the outside. The temporary enclosure main body 2 and the fixed support column 3 erected on the ground G, and the fixed support column Screen part 4 supported on the upper end part 3a of
And a configuration including:

The fixed support 3 has a height dimension higher than that of the temporary enclosure main body 2, so that its upper end 3 a is arranged to protrude above the temporary enclosure main body 2. In addition, a plurality of fixed columns 3 are arranged along the temporary enclosure body 2 in the horizontal direction in which the temporary enclosure body 2 extends.

The screen section 4 has a configuration in which a screen main body 5 formed of a sound insulating material and a pair of wires 6 and 6 temporarily provided between the fixed columns 3 and supporting the screen main body 5 are provided. ing.

The screen body 5 is formed in a bellows shape, and has an upper end edge 5a and a lower end edge 5b movably supported along upper and lower wires 6, 6.
Thereby, it can be folded and unfolded along the wires 6 and 6. When the screen main body 5 is unfolded, the screen part 4 is moved to the temporary enclosure main body 2.
Extend continuously in a certain area above the upper part.

When such a temporary enclosure structure 1 is used on site, the screen main body 5 is unfolded along the wires 6 and 6, for example, when there is no wind, which has a great influence of the SPM on the ground. Temporary enclosure body 2 for part 4
To be continuously located above the As a result, the height of the temporary enclosure structure 1 itself is substantially increased, and SP
The spread of M to the ground can be reduced. Also, SP
At the time of strong wind with large diffusion of M, the screen main body 5 is folded and stored along the wires 6 and 6, so that only the temporary enclosure main body 2 of the temporary enclosure structure 1 can be used.

As described above, this temporary enclosure structure 1
It is possible to change the height according to weather conditions and the like. In this case, since the fixed portion may be only the portion of the temporary enclosure main body 2, the height of the temporary enclosure main body 2 may be changed. As in the conventional case, the height of the SPM to the surrounding environment is minimized by minimizing the effect on the temporary design and the like and the increase in cost when installing the temporary enclosure structure 1 by setting the minimum height required for construction as in the past. The addition rate can be reduced.

Further, in this case, the temporary enclosure structure 1 can be realized with a simple configuration in which the screen portion 4 can be folded and unfolded along the wires 6 and 6 laid between the fixed columns 3. Therefore, the increase in the construction cost due to the variable height dimension does not become large.

Further, since the screen main body 5 is formed of a sound insulating material, noise generated from the construction site can be cut off by the screen main body 5, whereby noise to the periphery can be reduced. Comprehensive consideration can be given to the impact of construction work on the surrounding environment. Further, by reducing the addition rate of air pollutants such as NOx generated from the construction site, it is possible to contribute to environmental conservation.

In the above embodiment, another configuration may be adopted without departing from the spirit of the present invention. For example, as in a temporary enclosure structure 1 ′ shown in FIG. 2, a wire 6 ′ is provided between the upper ends of the fixed columns 3, and the screen main body 5 ′ is wound and unfolded using the wire 6 as a winding shaft. The same effect as in the above-described embodiment can be obtained even if the roll screen 7 is formed by using the roll screen 7.
