Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a partition wall excellent in fireproof sound insulation and workability. <Conventional technology> Conventionally, as a partition wall, a so-called double-panel structure in which a wall material is attached to both sides of a pre-established stud and a hollow layer equal to the thickness of the stud is provided. There is. The wall material is formed by laminating a flat plate made of a gypsum boat or the like in a double or triple manner, and has a predetermined fireproof and sound insulation performance by the hollow layer. <Problems to be solved by the invention> As a method for wiring or piping such as electricity on such a partition wall that requires particularly fire-resistant performance, a hole is made in the fire-resistant wall, and connection and operation of electricity and equipment are performed. In general, it is common practice to provide fireproof joints and provide wiring and piping using the hollow layer of the partition wall. is there. In addition, this method does not require
Since wiring and piping may be passed through a stud made of a molded lightweight steel frame or the like, it may take a lot of time to perform the work, and a decrease in performance such as fire resistance may be considered. As described above, when wiring or piping for electricity or the like is performed, a cause occurs that the fire resistance and strength of the partition wall are reduced. In addition, there has been a problem that it takes time to repair joints and the like and to perform wiring and piping work. <Means for solving the problem> Therefore, in the present invention, on both sides of the wall frame, a fireproof sound insulation panel provided with a plurality of ridges on the surface, and a sound insulation panel attached to the ridges. The wall material is laminated and disposed, and furthermore, a piping or a cavity for filling sound absorption is formed between the fireproof sound insulation panel and the sound insulation panel. <Operation> Wiring / piping of electricity or the like utilizing the cavity formed in the wall material by the above-mentioned means and the ridge of the fireproof sound insulation panel and the sound insulation panel attached to the protruding end surface of the ridge. It can be performed. In addition, the entire partition wall serves as a sound insulating wall having a predetermined performance, and a wall body having a large fire sound insulating performance including a hollow layer portion sandwiched between one fireproof sound insulating panel and the other fireproof sound insulating panel in the partition wall. <Example> Hereinafter, the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of a fire-resistant and sound-insulating partition showing one embodiment of the present invention, and FIG. 2 is a longitudinal sectional view of the partition. In the figure, a fire-resistant and sound-insulating partition wall 1 is composed of a wall frame composed of upper and lower liners and studs 2, and wall members 3, 3 attached to both sides thereof. First, the configuration of the wall frame and the wall material 3 will be described. The wall frame is composed of an upper liner 21 and a lower liner 22 made of a lightweight steel frame, and a stud 2 is erected at a predetermined interval P between both runners. On the other hand, the wall materials 3, 3 make the underlaying plates 31, 31 abut against the wall frame as necessary, and the fireproof soundproofing panels 32a, 32b and the fireproof soundproofing panels 32a, 32a, Sound insulation panels 33, 33 laminated with 32b to form the surface of the partition wall 1
It is composed of The underlaying plate 31 is made of a gypsum board or the like having high fire resistance and sound insulation performance. On the other hand, the fireproof and soundproof panels 32a and 32b are also made of a glass fiber reinforced lightweight aggregate molded board, a glass fiber reinforced cement board, or the like, which has high fireproof performance and soundproof performance. On one surface thereof, a plurality of ridges T are integrally formed at predetermined intervals in a vertical direction. The sound insulation panel 33 is made of a material having high sound insulation performance, and for example, a gypsum boat or the like is used. Means for constructing the fireproof and soundproof partition wall 1 based on the above configuration will be described. The upper runner 21 is screwed to the ceiling 4 and the lower runner 22 is screwed to the floor 5 at the same time.
... are erected to form a wall frame. Underlay plates 31, 31 are attached to both sides of such a wall frame with tapping screws or the like. As a result, a hollow layer is formed in the wall frame, and glass wool 7 and the like are disposed in the hollow layer 6 to perform a sound absorbing process around the upper and lower ends. Next, the fireproof and soundproof panel is placed so that the ridge T faces the hollow layer 6 (see FIGS. 1 and 3).
32a and 32b are staggered to the underlaying plates 31 and 31. Therefore, a portion sandwiched between one fireproof sound insulation panel 32a and the other fireproof sound insulation panel 32b becomes a fireproof wall having predetermined performance. Further, in the fireproof soundproofing panels 32a and 32b, the ridges T serve as ribs, and the rigidity of the plate B is improved. As a result, the sound insulation performance of the fireproof sound insulation panels 32a and 32
The sound insulation performance of b is improved. Further, sound insulation panels 33, 33 are attached to the protruding end surfaces of the protruding ridges T. FIG. 3 is a partially omitted cross-sectional view of the fireproof and soundproof partition wall 1. In the figure, the ridge T and the sound insulation panel 33 in the wall material 3 are shown.
Thereby, the plate portion S becomes a cavity. This cavity is used for wiring and piping for electricity and the like. Filling other unused cavities with a sound absorbing material improves the sound insulation performance and the panel rigidity. In order to connect a switch box (not shown) or the like provided on the surface of the partition wall 1 to the wiring / pipe, the ridge T is directed outward, so that the fireproof sound insulation panel 32 is not cut off. Only the sound insulation panel 33 needs to be cut out. In this way, the partition wall 1 having the laminated wall material attached to both sides of the wall and having a cavity between the laminated layers is constructed, and the arrangement / pipe and the sound insulation wall having high fire resistance are provided. As shown in FIG. 3, when the predetermined one protruding portion T and the sound insulation panel 33 are adhered using the damping material 8, the vibration transmission is prevented, and the sound insulation performance can be further improved. FIG. 4 is a diagram showing characteristics of sound transmission loss of a material used for the fireproof sound insulation panels 32a and 32b and the sound insulation panels 33 and 33.
In the figure, the horizontal axis indicates frequency (Hz), and the vertical axis indicates sound transmission loss (dB). As can be seen from the figure, the fireproof sound insulation panels 32a, 32
The two materials designated as b have better sound insulation performance than the gypsum board, which is generally used as a conventional partition wall, and by adding a protruding portion T, the bending and strength of the board are increased. Become. Therefore, the out-of-plane rigidity is increased, and the sound insulating performance in the low range is improved by filling the cavity with a sound absorbing material. And it greatly contributes to the improvement of the sound insulation performance of the entire partition wall. The fireproof soundproofing panels 32a and 32b are separately provided with a plate portion B and a projecting portion T using an asbestos cement material, a glass fiber reinforced cement plate, or a gypsum board.
May be integrated by bonding. <Effects of the Invention> As described above, the fire-resistant and sound-insulating partition wall of the present invention has a plurality of cavities formed in each wall material attached to both sides of the wall.・ Piping can be performed easily. Further, since it is not necessary to cut out the fire-resistant wall and the stud largely for wiring and piping, the fire-resistance performance of the partition wall and the strength are not reduced.
