Field of the Invention The present invention relates to an improvement of a temporary shroud used at a construction site or a material storage. 2. Description of the Related Art Conventionally, a temporary shroud of this type is, for example, shown in FIG.
As shown in (1), a mounting hole 20 is provided at an appropriate position of the plate body 1, and a hook bolt 21 is inserted into the mounting hole 20 and fixed with a nut 22 or the like. Such a temporary shroud is shown in FIG.
As shown in the figure, the hook portions 21a of the hook bolts 21 are respectively hooked on a plurality of horizontal frames 10a of the support framework 10 provided on the outer periphery of the construction site or the material storage area, so that the hooks 21a are attached to the support framework 10 and constructed. The site and material storage are surrounded. [0003] By the way, at a construction site or a material storage area, noise is generated during the foundation work or during the loading / unloading operation of the material, and this noise surrounds the construction site or the material storage area. Not only did they leak out of the temporary shroud, causing inconvenience to nearby residents and passersby, but also at the construction site and in the material storage area, noise was reflected on the temporary shroud, giving workers discomfort. However, the above-mentioned conventional temporary enclosure plate has a problem that such noise cannot be dealt with at all. Accordingly, the present invention has been made to solve the problems of the above-mentioned conventional temporary enclosing plate. [0005] Therefore, in the temporary enclosure of the present invention, a sound insulating material 2 made of a soft vinyl chloride sheet is provided on the back surface of the plate bodies 1 and 1, One side ends are connected to each other via a bendable structure made of a flexible member 5 fixed so as to sandwich one side of the plate bodies 1 and 1 and to the other side ends of the plate bodies 1 and 1, respectively. A bent portion 3a formed on the side body 3 together with a plurality of holes 4 provided at appropriate positions in the upper, middle and lower portions of the side body 3 or a fitting portion 3b formed on the side body 3 Are provided on the side body 3 respectively. According to the temporary shroud of the present invention, the noise generated at the construction site or the material storage is controlled by the soundproof material 2 provided on the back of the plate body 1.
The sound is absorbed as much as possible. Furthermore, in the temporary shroud according to the present invention, even if there is a height difference between a plurality of horizontal frames of the support frame provided on the outer periphery of the construction site or the material storage area, the upper part, the central part, and the lower part of the side body 3 are appropriately positioned. Any one of the plurality of holes 4 provided near the horizontal frame approaches the horizontal frame. Further, the temporary enclosing plate of the present invention can be used as a corner portion by being bent at an appropriate angle from the bendable structure. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the structure of a temporary enclosure according to the present invention will be described in detail with reference to the accompanying drawings. In the temporary enclosure of the present invention, a soundproof material 2 is provided on the back surfaces of the plate bodies 1 and 1. Then, one side end of the plate main bodies 1 and 1 is bent inward to form side bodies 3, respectively, and these side bodies 3 are provided with connecting portions. The connecting portion may be a bent portion 3a formed on the side body 3 as shown in FIGS. 1 and 2 together with holes 4 provided at appropriate positions on the upper, middle and lower portions of the side body 3, respectively. 3,
As shown in FIG. 4, a fitting portion 3b formed on the side body 3 can be used. In addition, the said connection part is the hole 4, the bending part 3,
a, all of the fitting portions 3b may be combined. As shown in the figure, a plurality of holes 4 are provided at appropriate positions in the upper, central, and lower portions of the side body 3. This is such that even if there is a height difference between a plurality of horizontal frames of a support framework provided on the outer periphery of a construction site or a material storage area, one of these holes 4 approaches the horizontal frame. In addition, the shape of the hole 4 is not limited to the circular shape shown in the embodiment, but can be implemented as an appropriate shape such as a square, a rectangle, and an ellipse. Further, as shown in the drawing, the temporary enclosing plate of the present invention has the other ends of the plate main bodies 1, 1 connected to each other via a bendable structure. A flexible member 5 is used as the bendable structure.
The width of the rubber body is about 5 to 10 mm made of natural rubber, synthetic rubber, flexible synthetic resin, or the like. The temporary shroud thus configured can be bent at an appropriate angle from the portion of the bendable structure, and thus is used for a corner portion. The soundproofing material 2 is made of a soft vinyl chloride sheet, and is provided on the back surface of the plate main body 1 by using an adhesive or screwing. be able to. Hereinafter, a sound transmission loss test of the soft vinyl chloride sheet used as the soundproof material 2 will be described. The test results are shown in Tables 1 and 2. The sound transmission loss test was conducted according to JIS A
Performed according to 1416. (Sample 1) Soft vinyl chloride sheet: Total thickness 1.2 mm, 3.2 kg / m 2 (Sample 2) Soft vinyl chloride sheet: Total thickness 1.6 mm, 3.5 kg / m 2 1) [Table 2] As shown in FIG. 5, a plurality of the temporary shrouds of the present invention constructed as described above are mounted on a plurality of horizontal frames 10a of a support framework 10 provided on the outer periphery of a construction site or a material storage area. Side by side, butts each other's side bodies 3,
The center line and the lower side can be attached to the support frame 10 by passing the number wires 11 through the holes 4 of the side body 3 adjacent to each other and winding the number wires 11 around the horizontal frame 10a. Further, in the case where the bent portion 3a or the fitting portion 3b is formed on the side body 3, the bent portion 3a and the fitting portion 3b adjacent to each other are butted together, and the abutted portion is formed. By fitting a connection fitting (not shown), fixing the connection fitting to the horizontal frame 10a, or passing the wire 11 through the hole 4 at the butted portion in the same manner as described above, and winding the wire 11 around the horizontal frame 10a, A temporary shroud can be attached to the support framework 10. According to the temporary shroud of the present invention, the noise generated in the construction site or the material storage area is absorbed as much as possible by the soundproofing material 2 provided on the back surface of the plate body 1, so that the construction site or the material storage area is used. The noise hardly leaks out of the temporary shroud surrounding the building, minimizing the inconvenience to nearby residents and pedestrians, and the noise is absorbed by the temporary shroud even at construction sites and material storage areas without being reflected by the temporary shroud. Therefore, discomfort to the operator can be reduced as much as possible. Furthermore, even if there is a height difference between a plurality of horizontal frames of a support framework provided on the outer periphery of a construction site or a material storage area, the temporary shroud of the present invention can
Any one of the plurality of holes 4 provided at an appropriate position in the lower portion approaches the horizontal frame, so that the number line can be easily wound and can be easily attached to the support frame. Further, the temporary enclosure plate of the present invention can be used as a corner part by being bent at an appropriate angle from the portion of the freely bendable structure, and therefore has excellent versatility.
