〔Example〕

Hereinafter, the present invention will be described in more detail based on embodiments shown in the drawings.

Here, FIG. 1 is an overall perspective view of a fixed-shaped prefabricated soundproof tent, and in the same figure, 1 is a fixed-shaped prefabricated soundproof tent assembled to surround a noise-generating part at a construction site; The type soundproof tent 1 is installed to reduce noise generated at a construction site, and the frame of the fixed type prefabricated soundproof tent 1 is composed of pillars 2 and horizontal members 3 that connect the pillars 2. .

As shown in FIG. 2, a total of six columns 2 are arranged at predetermined intervals at positions surrounding the noise-generating part of the construction site. The pillars 2 are respectively erected at the four corners of the rectangle and at the midpoint on the longitudinal line, and the pillars 2 are connected to each other by horizontal members 3 installed horizontally at the upper and lower parts. These struts 2 and cross members 3 constitute a rectangular bone assembly. The pillars 2 and the cross members 3 have predetermined dimensions in advance so that they can be assembled smoothly.

The column 2 has a circular rod shape, and a jack base 2a serving as an adjustment member for adjusting the height and inclination of the column 2 is screwed into the lower end of the column 2. Hook receivers 2b for connecting with the cross member 3 are formed on the side circumferential surfaces of the upper and lower parts of the support column 2. Hook receiver 2 of post 2 installed at the midpoint
b are formed on both side circumferential surfaces (see FIG. 3B), and hook receivers 2b of the pillars 2 installed at the four corners are formed on the side circumferential surfaces at an angle of 90 degrees (see FIG. 3C).

The upper cross member 3a installed horizontally at the upper part and the lower cross member 3b installed horizontally at the lower part are formed in a truss shape, and the lower cross member 3b is made larger than the upper cross member 3a. Furthermore, upper and lower hooks 3c are formed on both side edges of the upper cross member 3a and the lower cross member 3b, and are easily engaged with the hook receivers 2c and can be easily removed.

Side panels 4 are attached to all sides of the rectangular bone assembly composed of struts 2 and cross members 3 without gaps, and ceiling panels 5 are attached to the ceiling surface of the bone assembly without gaps.

The side panel 4 is constructed by attaching a soundproof sheet 4b and a sound absorbing material 4c to a rectangular frame 4a. The frame 4a is formed by bending or connecting rod shapes. On one side of the frame 4a, upper and lower hooks 4d are formed which are easily engaged with the cross member 3 and can be easily removed. The soundproof sheet 4b is a rectangular sheet with a similar shape that is slightly larger than the frame 4a, and the margins of the soundproof sheet 4b protruding from the upper and left ends of the frame 4a (see Fig. 8B) are folded inward. The soundproof sheets 4b are attached to the frame 4a by overlapping them, and the lower and right ends of the soundproof sheet 4b are attached so as to partially protrude from the frame 4a to create a blank space. The blank space at the right end of the soundproof sheet 4b partially overlaps with the adjacent separate side panel 4 to reduce leakage of noise to the outside and enhance the soundproofing effect. Similarly, the lower end of the soundproof sheet 4b is bent and comes into contact with the ground to reduce leakage of noise to the outside and enhance the soundproofing effect. 4
e is a joining sheet for attaching the soundproof sheet 4b to the frame 4a. The sound absorbing material 4c is attached by adhesive or the like to the surface that will be on the indoor side when the side panel 4 is attached to the side surface of the bone assembly.
The soundproofing material 4c is made of a flame-retardant material with sound-absorbing properties, such as a sponge sheet, and its surface has an uneven shape to increase the surface area.
Sound absorption effect is enhanced. Note that the side panels 4 attached to the corners are bent from the center at approximately right angles to the left and right. Further, one of the side panels 4 is provided with an entrance/exit 4f.

The ceiling panel 5 is constructed by attaching a rod-shaped frame 5b to a rectangular soundproof sheet 5a. The longitudinal side of the soundproof sheet 5a is longer than the width of the ceiling. The frame 5b is a joining sheet 5c
and is attached to the soundproof sheet 5a. Two frames 5b are arranged parallel to the longitudinal direction of the soundproof sheet 5a, and both sides of the frames 5b are cut. Note that a sound absorbing material is attached to the ceiling panel 5 using an adhesive or the like as necessary. The sound absorbing material is attached to the surface that becomes the indoor side when the ceiling panel 5 is attached to the ceiling surface of the bone assembly.

Next, a method of assembling a fixed-form prefabricated soundproof tent having the structure of the above embodiment will be explained.

First, struts 2 are placed at predetermined intervals at positions surrounding the noise-generating part of the construction site. The size and arrangement interval of the supporting columns 2 to be used are determined depending on the size of the noise generating section.

Next, the column 2 is erected perpendicularly to the ground, and the lower cross member 3b is connected to the lower part of the column 2 while adjusting the height of the column 2 with the jack base 2a attached to the lower end of the column 2. The connection can be easily performed by simply inserting the hook 3c of the lower cross member 3b into the hook receiver 2b of the column 2 from above. All of the lower cross members 3b are connected to the struts 2 using the installation method described above. After the installation of the lower cross member 3b is completed, the upper cross member 3a is connected to the upper part of the column 2. This connection is also simply the hook 3 of the upper horizontal member 3a.
This can be easily done by simply inserting c into the hook receiver 2b of the support column 2 from above. Next, the center stop and the diagonal steady stop are attached to the upper end of the post 2, completing the assembly of the bone assembly.

Next, side panels 4 are attached to all sides of the bone assembly. The side panels 4 are attached starting from the corners. A side panel 4 exclusively for the corner is attached to the corner, and then the side panels 4 are attached one after another while considering the entrance/exit. A side panel 4 dedicated to the entrance is attached to the place that will become the entrance. The side panel 4 can be easily attached by simply hooking hooks 4d provided at the upper and lower ends of the side panel 4 to the upper ends of the upper cross member 3a and the lower cross member 3b.
In this case, since the side panel 4 has a size suitable for the work, its handling becomes easy. and,
While the side panel 4 is hooked, it is moved along the upper horizontal member 3a and the lower horizontal member 3b, and is brought into close contact with the separate side panel 4 located next to it as much as possible so as not to create a gap. Further, the margin portion of the soundproof sheet 4b of the side panel 4 is overlapped with the adjacent separate side panel 4. By repeating the above operations, the installation of the side panel 4 is completed.

After completing the installation of the sides of the bone assembly, attach the remaining ceiling surface. For installation on the ceiling surface, for example, the adjacent ceiling panels 5 are
The tents are overlapped by about 100 mm and installed from the edge of the ceiling toward the center, taking into account the opening in the ceiling, to complete the assembly of the fixed-form prefabricated soundproof tent 1.

In addition, the number of workers required to assemble the fixed-form prefabricated soundproof tent 1 is 2 to 3 people, depending on the situation.
It can be assembled in 15-30 minutes. Moreover, the above-described prefabricated soundproof tent 1 is disassembled in the reverse order of assembly. Disassembled parts can be reused for the next assembly, making effective use of the parts.
