Description

[Detailed description of the invention] The present invention relates to a fireproof and sound insulating partition wall.

Conventional fire-resistant partition walls are generally known to have fire-resistant boards attached to both sides of a lightweight steel frame base, but such fire-resistant partition walls have metal studs used inside them that cause the internal temperature to rise and the temperature on the back surface to rise. This causes problems in terms of fire resistance.

Regarding sound insulation performance, in the case of a partition wall with a symmetrical structure using metal studs, the difference in the Young's modulus of the surface fireproof board increases the resonance effect of sound.
) occurs, and the sound insulation value at a certain frequency decreases significantly.

-! When a conventional fire-resistant and sound-insulating partition wall is used in a mid-to-high-rise building, if a displacement of about 1/200 is applied, a clanking sound will occur because the metal studs and fireproof board are attached with screws. This is a factor that significantly lowers the rating of buildings, especially in hotels, condominiums, etc.

Therefore, box-shaped hollow panels conventionally formed from gypsum board were placed one after another with a slight gap left between their sides, and every other panel was placed side by side with a slight 111 position in the width direction. There is a known fireproof partition wall in which fireproof boards are attached to the front and rear surfaces of the fireproof board, and noncombustible fibers such as rock wool are filled between adjacent hollow panels and in the small gaps between each hollow panel and the fireproof board. However, filling such a small gap with rock wool has the drawback that the construction is extremely complicated and difficult. In terms of sound insulation, the fireproof boards on both the front and rear surfaces allow sound to be easily transmitted through the box-shaped hollow panels (a coincidence effect is expected to occur).

The present invention was proposed in order to solve these problems, and consists of one hollow panel made of gypsum board between the upper and lower groove type runners installed on the ceiling slab and the floor, respectively.
They are arranged at predetermined intervals so that their widthwise positions are slightly apart, and fireproof boards made of gypsum board, calcium silicate board, etc. are glued to the front and rear surfaces of each hollow panel, respectively. This invention relates to a fireproof and sound insulating partition wall characterized in that the gap between the fireproof board and the hollow panel is filled with noncombustible fibers such as rock wool.

In the partition wall according to the present invention, the front and rear surfaces thereof are arranged between the upper and lower groove type launches respectively arranged on the ceiling slab and the floor.
A fire-resistant panel made of gypsum boards, calcium silicate plates, etc. that are glued to the front and rear surfaces of a group of hollow panels made of gypsum boards arranged at predetermined intervals so that the widthwise position of every other panel changes slightly. , is composed of fireproof boards with excellent heat insulation properties, and non-combustible fibers are arranged in double layers in the hollow part formed between the fireproof boards on the front and rear surfaces due to the gaps between the fireproof boards and the hollow panel. , and has a sufficient amount of air space, so it has excellent fire resistance and heat insulation properties that conventional partition walls do not have.Furthermore, the front and rear fire-resistant boards are isolated from each other with non-combustible fibers, so there is no noise. The vibration of the plate is not transmitted, and the sound insulation value of the front and rear surfaces is sufficiently large, demonstrating extremely high sound insulation performance.

Furthermore, the fireproof ports on the front and rear sides are made of the same material as the hollow panel, and do not require the use of screws or the like. The present invention has many advantages, such as the fact that it does not occur.

The illustrated embodiment of the present invention Z will be described below.

(IXI') is a hollow panel made of gypsum board, and its upper and lower ends are connected to the ceiling slab (2) and the floor (3).
The groove-shaped runners (4X4') installed in Attach a fireproof board (5 x 5') such as gypsum board or calcium silicate board to each side using adhesive. In addition, (6) (
A spacer made of gypsum board or calcium silicate board interposed between the vertical flange of the runner (4x4') and the two lower ends of the hollow panel (1) (1').

A small gap between the fireproof board (5) and the hollow nominelle (2X2') is filled with noncombustible fibers (7X7') 'a', and the noncombustible fibers (7) (7') are further spread out (6 ) (6') is layered on the fireproof board (5) between the hollow panels to form a partition wall.

In addition, the hollow panel (202) has a flexible sheet (8) of paper etc. glued to at least one side of the plasterboard, and cut grooves (9) 7 with a depth that reaches the sheet are provided in parallel at predetermined positions. Insert reinforcing piece (10) v in the middle using the same ■ cut, ■
The cut groove and the contact surface with the reinforcing piece (10) are bonded to form a box shape.

Since the illustrated embodiment is constructed as described above, fireproof blanks 5) (5') such as calcium silicate boards and plasterboards with excellent fire resistance and heat insulation properties are arranged on the front and rear surfaces of the partition walls. , non-combustible fibers (7X7')/l' in the hollow space between each board
Since it is arranged in two layers and maintains a sufficient air space, a partition wall with excellent fire resistance and heat insulation is constructed.Furthermore, the fireproof boards (5) (5') on the front and back sides are made of non-combustible fibers (5').
7) Since it is isolated by (7'), sound plate vibrations are not transmitted, and a sufficient sound insulation value is obtained between the front and rear surfaces, demonstrating extremely high sound insulation performance.

Also, upper and lower runners (4 to 4') and hollow panels (2X2')
A fireproof spacer (6 x 6') made of calcium silicate board or gypsum board made of the same material as the panel is used between the panels, and the fireproof bows (5 x 5') on the front and rear sides are also hollow and ξ flannel ( Do not use screws, etc., using the same material as 2 and 2') (as they are bonded with adhesive,
Track noise does not occur even with large displacements between floors in mid-to-high-rise buildings.
