Description

[Detailed Description of the Invention] << Industrial Application Field >> The present invention relates to a partition wall of a building, which is simple in construction and excellent in crime prevention and sound insulation, and is particularly suitable as a boundary wall of a super high-rise building. It provides a fireproof partition wall.

<< Prior Art >> A partition wall that is a boundary wall between rooms in a concrete structure such as a high-rise apartment house, a building, or a hotel is desired to have excellent sound insulation and fire resistance.

As such a partition wall, there is one conventionally disclosed in Japanese Utility Model Publication No. 59-35690.

This is an outer partition plate made of gypsum board placed at an appropriate distance on the outside of an inner partition plate made of gypsum board opposite each other with an appropriate distance, and a sealed space between the inner partition plates and between the inner and outer partition plates. And the inner and outer partition plates are fixed with a gypsum bond.

<Problems to be solved> However, since the conventional structure has a structure in which the inner and outer partition plates are fixed with a gypsum bond, in order to have sufficient strength as a wall material, the inner and outer partition plates The thickness of each plate must be increased. However, if the inner and outer partition plates are made thicker, the volume that can be used as a room becomes smaller and the weight as a wall becomes heavier, so there is a problem that they cannot be used as a boundary wall of a high-rise building, especially a super high-rise building.

In addition, since the wall has a structure of only gypsum board, it is vulnerable to destructive activities and has a problem in terms of crime prevention.

<< Means for Solving Problems >> The present invention provides a fireproof partition wall with excellent sound insulation and crime prevention that can be used as a boundary wall of a super high-rise apartment house. In a partition wall consisting of plates placed opposite to each other with a certain distance, and placed back to back with an appropriate distance, a partition wall is formed between each inner partition plate in a closed space formed between the inner partition plates. It is characterized in that it is arranged in a state having a gap, and that this partition wall is constituted by sandwiching a metal core material between two gypsum boards.

<Operation> The present invention has a structure in which inner and outer partition plates are opposed to each other with a certain distance, and they are arranged back to back with an appropriate distance, and partition walls are formed in the closed space formed between the inner partition plates. It is arranged with a gap between and, and since this partition is configured by sandwiching the metal core material with two plaster boards, sandwich the metal core material with two plaster boards. A high-rigidity bulkhead is added in the enclosed space between the inner partition plates to act as a strength member, and as a whole fire-resistant partition wall, the individual gypsum boards that make up the wall are thin. However, it will have sufficient strength as a wall.

Moreover, since the partition walls are arranged in the space formed between the inner partition plates with a gap between each of the inner partition plates, the overall thickness of the wall body does not become thick and the volume of the room Never narrows.

Further, since the partition walls are arranged in the space formed between the inner partition plates with a gap between each of the inner partition plates, four cavities are arranged in layers in the wall. Therefore, the sound insulation is also high.

Further, since the metal core material is arranged on the partition wall, it becomes strong against the destructive activity.

<< Embodiment >> The drawings show an embodiment of the present invention. FIG. 1 is a perspective view of an essential part, FIG. 2 is a longitudinal sectional view of the essential part, and FIG. 3 is a lateral sectional view of the essential part.

This partition wall (1) forms a boundary wall between homes in a super high-rise apartment building, is placed at a certain distance from each other, and is fixed to both sides of a runner material (2) with an ϕ-shaped cross section. Gypsum board inner partition plate (3), gypsum board outer partition plate (4) arranged on the outside of the inner partition plate (3) at a fixed distance, and runner material (2)
It is composed of partition walls (6) arranged in the space (5) between the inner partition plates (3) having a width of.

The inner partition plate (3) is arranged in a state where the unit gypsum board (3a) is butt-connected with its side end faces, and the joint parts (7) of the inner partition plates (3) facing each other are It is formed to be displaced by a half pitch.

In the joint part (7) of the inner partition plate (3), a gypsum board reinforcing plate (8) having a half width of the unit gypsum board (3a) is covered from the outside of each inner partition plate (3) so as to cover the joint part. It is glued. Therefore, the reinforcing plates (8) are arranged in a zigzag shape in plan view.

A unit gypsum board (4a) having the same width as the unit gypsum board (3a) of the inner partition plate (3) is arranged on the outer side of each reinforcing plate (8) in such a state that the side end faces thereof are butt-connected to each other, and then joined. Each unit gypsum board (4a) is bonded to the reinforcing plate (8) to form the outer partition plate (4) with the part (9) positioned at each reinforcing plate (8). Thereby, in the part without the reinforcing plate, between the inner partition plate (3) and the outer partition plate (4),
An outer hermetically sealed space (10) having the same thickness as the reinforcing plate (8) is formed, and the outer hermetically sealed space (10) is arranged in a zigzag shape in plan view.

The partition wall (6) is obtained by adhering the plasterboards (12) and (12) from the front and back surfaces of the thin steel plate metal core material (11) so that the metal core material (11) is two gypsum board (12) (12). ), The partition wall (6) is supported by the center leg (13) of the runner material (2) in a non-contact state with the inner partition plate (3). As a result, the space (5) between the inner partition plates (3) formed by the width of the runner material (2) is divided into two by the partition wall (6).

In the figure, reference numeral (14) is a gypsum bond arranged at an appropriate vertical interval between the side edge of the reinforcing plate (8) and the outer surface of the inner partition plate (4), and (15) is the partition wall (6). The glass wool is stretched on both outer sides, and the glass wool (15) may be omitted.

As the adhesive for adhering the reinforcing plate (8) and the inner / outer partition plates (3) and (4), a plaster-based adhesive, a vinyl acetate-based adhesive, or an acrylic adhesive is used. . Also,
As the metal core material (11), a porous thin steel plate or a wire mesh is used in addition to the above-mentioned thin steel plate.

Further, the partition wall (1) is attached to the rising wall and floor wall of the building by a structure capable of coping with interlayer displacement.

In the partition wall (1) having the above-described configuration, the wall body has a three-layer structure of gypsum board, and an independent closed space is formed between the partition wall (6) and each inner partition plate (3). In addition, since the closed spaces (10) that are independent between the inner and outer partition plates (3) and (4) are also arranged in a zigzag manner, the sound of the wall is greatly attenuated and high sound insulation is exhibited. In addition, since the metal core material (11) is arranged in the partition wall (6), it has sufficient strength against destructive activity.

Further, since the partition wall (10) is arranged within the width of the runner material (2), the thickness of the wall body does not increase and the floor area of the room does not decrease.

Further, the wall body is made of only a refractory material, and since the closed space (5) between the inner partition plates (3) and (3) is partitioned by the partition wall (6), it is added to one wall surface. It is difficult for heat to transfer to the other wall surface, and it exhibits a sufficient function as a fireproof wall.

FIG. 4 shows another embodiment of the present invention, which is constructed by using a channel type runner material (2), in which a partition wall (6) is attached to one inner partition plate (3) of a gypsum board piece. It is designed to be fixed via a spacer (16) such as. In this case, the spacers (16) are arranged at appropriate intervals in the lateral and height directions of the wall.

<Effects> The present invention has a structure in which inner and outer partition plates are opposed to each other with a certain distance, and they are arranged back to back with an appropriate distance, and partition walls are provided in the enclosed space formed between the inner partition plates. And are arranged in a non-contact manner, and the partition wall is configured by sandwiching the metal core material between two gypsum boards, so that the following effects can be obtained.

In the sealed space (5), the free transmission of sound due to air vibration is blocked by the partition wall (6), so that the sound insulating performance can be improved.

Moreover, the bulkhead (6) has two gypsum boards (12) (1
Since it is composed of 2) and the metal core material (11), it has high rigidity and is hard to be vibrated by sound waves, so the sound insulation can be further enhanced.

(B) Prevention of breakage of fireproof partition wall The partition wall (6) has a metal core material (11).
1) is tough unlike gypsum board and cannot be easily broken with a hammer.

As a result, it is possible to well prevent the fireproof partition wall from breaking into the adjacent room, and the crime prevention effect is high.

(C) No increase in wall thickness In addition, since the partition wall is arranged in the closed space formed between the inner partition plates, the partition wall is partitioned without increasing the thickness of the wall body. Since it does not reduce the floor area of the room and does not have a heavy structure, it is possible to obtain a partition wall with high sound insulation and crime prevention effects that can be used as a partition wall for a super high-rise house.

Furthermore, since the wall is made up of only refractory material and has a three-layer structure with an air layer inside, it is difficult for heat applied to one wall surface to transfer to the other wall surface, and sufficient fire resistance is achieved. Can be demonstrated.
