Description

[Detailed description of the invention] The purpose of the invention is to improve the commercial value, soundproofing performance, and work efficiency of a partition wall that forms a soundproof space between front and back wall panels.

Conventionally, the one shown in FIG. 5 is known.

That is, the front and back wall panels 1 and 2 are placed opposite each other with a soundproof space 3 in between, and ribs 4 protrude from the left and right side edges of the front and back panels 1 toward the back panel 2.

The ribs 4 and the flat side edges 5 of the back wall panel 2 are joined with an adhesive 6 over the entire length in the height direction.

However, in this case, each of the soundproof spaces 3 becomes a narrow closed space that is independent of each other, and the intermediate portions of both the front and back wall panels 1°2 are all floating, so they are easily excited and have poor strength and soundproofing properties.

In order to avoid this, the width of each wall panel 1, 2 is narrowed, but each wall panel 1, 2 looks narrow and poor, and the commercial value of the finished partition wall is inferior.

In order to solve this problem, the present invention connects the middle parts of the front and back wall panels with adhesive, thereby reinforcing each other and increasing the strength and soundproofing properties.

Moreover, by interposing a hygroscopic intervening plate within the thickness of the adhesive, the adhesive does not crumble and can be applied quickly.

Hereinafter, embodiments of the present invention will be described based on the drawings.

FIG. 1 is a perspective view of the front and back panels, which are formed of gypsum board and are indicated generally at 11.

The front wall panel 11 consists of a wall section 12 and ribs 13 that are continuous to the left and right edges of the wall section 12. Each rib 13 includes a deposit section 14, a folded edge section 15, and a folded section 16 that are continuous to the wall section 12.
It is formed by

In each connecting portion connecting the above-mentioned portions 12 to 16 in order, valley fold grooves 17 each having an opening angle of 90° are provided from the back surface of the front wall panel 1.
It is recessed.

In addition, since the opening edges of the two valley-fold grooves 17° 17 that sandwich the folding edge portion 15 are continuous with each other, by bending each connecting portion, a wall portion 12 can be formed with a wall on the back side of both left and right ends. A solid quadrangular prism-shaped rib 13 having a thickness twice that of the wall surface portion 12 is provided to protrude as shown in the imaginary diagram.

In this state, the tip of the folded portion 16 is tightly received and joined to the back surface of the wall portion 12.

Figure 2 shows the above-mentioned front wall panel 11 and flat back wall panel 2.
FIG. 3 is a cross-sectional plan view of a partition wall using 4 and 4, and FIG. 3 is a partially cutaway rear view thereof.

This partition wall is assembled in the following manner.

First, the upper runner 18, start end runner 19, lower runner, end runner (not shown), etc. are fixed to a fixed part F such as a fixed wall or pillar, and the front wall panel 11 is fixed by sequentially abutting these runners. .

Furthermore, the butt-matching side surfaces 20 of the front wall panel 11 are also bonded together using an adhesive.

Next, the adhesive 21 is applied to the protruding tips of the ribs 13 and their surroundings at a plurality of locations at appropriate intervals in the vertical direction of each rib 13 .

The adhesive 21 mainly contains gypsum and bond, and includes, for example, Tiger GL Bond manufactured by Yoshino Gypsum Co., Ltd.

Also, on the back surface of the wall section 12, adhesive 22 is applied in the same amount as the adhesive 21 at multiple locations at appropriate intervals vertically and horizontally, and water-absorbing interpolation boards made of plasterboard are applied.
3 is attached to the tip of the adhesive 22, and then the adhesive 22 is further placed on the intervening plate 23.

The interposed board 23 is obtained by cutting the same plasterboard as the front and back panels 11.24 into square shapes.

Then, the back wall panel 24 is placed opposite to the back surface of the front wall panel 11 with the soundproof space 25 at a distance, and is fixed to the runners and is bonded by coming into contact with each of the adhesives 21 and 22.

At this time, a ventilation gap 26 is created between the rib 13 and the back wall panel 24.

At this time, the initial drying and solidifying time of the adhesive 22 is shortened due to the water absorption effect of the intervening plate 23, and the need for holding the back wall panel 24 with a hand holding frame or the like can be eliminated within a relatively short time.

For example, immediately after assembling one back wall panel 24 by applying the adhesive 21 and 22 necessary for assembling one back wall panel 24 and inserting the intervening board 23, Work such as application of adhesives 21 and 22 and insertion of intervening plates 23 for assembling the next back wall panel 24 is started.

Therefore, even one person can efficiently assemble the wall.

In addition, by inserting the intervening board 23 into the adhesive 22,
The compressive strength of the adhesive 22 is also reinforced by the intervening plate 23.

Reference numeral 27 is a notch for fitting into the upper runner 18;
28 is mawaribuchi.

The surrounding tabs 28 are bonded after one or both of the front and back wall panels 11, 24 are fixed.

FIG. 4 shows a modification of the above embodiment.

That is, the ribs 29 are made to protrude toward the front wall panel 11 from both side edges of the back wall panel 24 as well.

Each rib 13, 29 of the front and back base wall panels 11.24 is formed of only the deposited portion 14.

The front and back wall panels 11.24 are arranged in a staggered manner so that the ribs 13, 29 are laterally shifted by half a pitch.

Each rib 13, 29 is bonded to the opposing wall panel 11.24 with adhesive 21.30, respectively.

Each rib 13, 29 Same dirt floor, front and back both wall panels 11.24
They are bonded to each other with adhesive 22 with intervening plates 23 interposed in vertical rows at appropriate intervals above and below.

Since the present invention is usurped as described above, it has the following effects.

(a) Each soundproof space communicates with each other through ventilation gaps to form a wide open space, so air can freely move back and forth between each other, buffering sounds and providing excellent soundproofing properties.

Furthermore, since the intermediate portions of the front and back wall panels are fixed by the bonding force of the adhesive, they are less susceptible to vibrations, which also provides excellent soundproofing properties, as well as increased strength and durability.

(b) Since both the front and back wall panels have excellent soundproofing properties and strength, their width can be made much larger, making them wider and heavier, and the commercial value of the finished partition wall is greatly increased.

(c) Since the adhesive absorbs water with the water-absorbing intervening plate and is quickly tightened, there is no need to take measures to prevent it from collapsing, and there is no need to wait for it to dry, so it can be used quickly and stably. construction can be carried out, greatly increasing work efficiency.
