Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method of constructing a partition wall made of gypsum board for a building.

For example, in concrete structures such as high-rise houses and buildings, partition walls that separate rooms are made of gypsum board (gypsum board or asbestos cement silicate board) to improve fireproofing, smokeproofing, and sound insulation. Calcium boards, etc.) are arranged in two layers, front and rear, and butted left and right.

(Prior Art) In the past, a stud was basically constructed by assembling columns and crosspieces in a lattice shape between the ceiling wall and floor wall of a building, and gypsum board was installed on the front and rear surfaces of the stud. was fixed with nails etc.

This construction method has the drawbacks that building the studs is time-consuming, takes a long time, and increases construction costs.

In order to eliminate this drawback, the present applicant previously proposed the construction method shown in FIGS. 7 and 8 (Japanese Patent Publication No. 62-9701).

That is, the upper runner 2 is fixed to the ceiling wall 1 of the building, and the lower runner 4 is fixed to the floor wall 3 by vertically opposing each other and running left and right. Place the upper board 6 of the plasterboard 5 on the front side in front of the upper runner 2, and the lower board 7 of the plasterboard 5 on the front side.
are brought into contact with the front surface of the lower runner 4, respectively, and fixed with a fixture 8 (such as a tack needle or needle).

An adhesive 13, an intermediate plate 15, and an adhesive 17 are adhered to the back surface of the gypsum board 5 on the front side in this order. The lower board 21 is brought into contact with the rear surface of the lower runner 4 on the upper board 20 of the gypsum board 19 on the rear side and on the rear surface of the upper runner 2, respectively, and fixed with fixtures 22, and the middle height part of the board is fixed with adhesive 17. The procedure consists of gluing the

In the partition wall built using this construction method, both the front and rear plasterboards 5 and 19 are glued with adhesive 1.
It has a strong double wall structure connected by 3 and 17.
This enabled us to omit the construction of studs in the conventional method, significantly shortening the construction period and significantly reducing construction costs.

In this construction direction, when a plurality of front and rear plasterboards are lined up side by side, the joints between the butted side edges become gaps, and the space on the front side and the space on the back side of the plasterboards are separated. There is a problem in that the sound insulation, smokeproofing, and flameproofing properties are reduced because of the communication between the two.

In order to solve this problem, it is possible to seal the joints, but it is difficult to fill the joints neatly with the joint compound, and the work is time-consuming, which is not desirable in terms of shortening the construction period and reducing construction costs. Additionally, the surface of the gypsum board becomes dirty due to adhesion of joint compound, reducing the commercial value of the finished partition wall. Moreover, the joint sealant may be interrupted, making it impossible to sufficiently eliminate the deterioration of sound insulation properties, etc.

(Objective of the present invention) The present invention is based on the above-mentioned invention shown in FIGS. 7 and 8, and provides sound insulation and The aim is to sufficiently improve smoke and flame resistance, as well as further shorten the construction period and reduce construction costs.

(Structure of the present invention) In order to achieve the above object, the present invention first fixes the plasterboard 5 on the front side to the upper runner 2 and the lower runner 4, as shown in FIGS. 1 to 6, for example. After finishing, the adhesive 11 is applied from top to bottom on the back side of the butt part 10 between the board side edges 9, 9, and the joint 12 between the board side edges 9, 9 is closed with this adhesive 11. Then, the adhesive 18 to which the side edges 23, 23 of the board 19 on the rear side are to be adhered is applied in advance in a vertically continuous manner along the vertical direction, and each plaster on the rear side is applied to this vertically continuous adhesive 18. By abutting and gluing the abutting portions 24 of the side edges 23, 23 of the boards 19..., the joints 25 between the board side edges 23, 23 are covered with a vertically continuous adhesive 18. This is the biggest feature.

Hereinafter, an example of the implementation procedure of the construction method of the present invention will be explained based on FIGS. 1 to 3.

An upper runner 2 is placed on the ceiling wall 1 of the building, and a lower runner 4 is placed on the floor wall 3 of the building, which are vertically opposed to each other and run left and right, and are fixed with concrete nails and adhesive (not shown). A plurality of plasterboards 5 on the front side are lined up side by side, and the upper board 6 is attached to the front of the wooden upper runner 2, and the lower board 7 is attached to the front of the wooden lower runner 4. Then, fix it with a fixing device 8 such as a tack needle or nail.

Apply adhesive 11 from top to bottom on the back side of the butt part 10 between the side edges 9, 9 of each plasterboard 5..., and apply this adhesive 11 to the joints 12 between the butts between the board side edges 9, 9. block.

On the back side of each gypsum board 5..., adhesives 13 and 14 are applied in a protruding manner from the top to the bottom of the butt portion 10 of the board side edges 9, 9 and the intermediate portion of the board in the left and right direction, respectively, and bonded. . The adhesives 13 and 14 are provided intermittently at appropriate intervals in the vertical direction.

Intermediate plates 15 and 16 are bonded to the protruding end surfaces of these adhesive plates 13 and 14, respectively. The intermediate plates 15 at the side edges 9 and 9 of the board are made of small pieces that are interrupted at appropriate intervals in the vertical direction. The intermediate plate 16 at the intermediate portion of the board is formed in a vertically long shape that continues from the vicinity of the upper runner 2 to the vicinity of the lower runner 4. Each intermediate plate 16 is formed by utilizing the remaining material of the front side plasterboard 5... or the rear side plasterboard 19, which will be described later.

Adhesives 17 and 18 are applied to the surfaces of the intermediate plates 15 and 16, respectively, and bonded. The adhesive 17 of the small piece intermediate plate 15 on the side edge of the board is discontinued at appropriate intervals in the vertical direction. Adhesive 1 is applied to the vertically long intermediate plate 16 at the middle of the board over its entire vertical length.
Arrange pieces 8 in a row vertically.

A plurality of gypsum boards 19 on the rear side are lined up side by side, and the upper part 20 of the board is brought into contact with the rear face of the upper runner 2, and the lower part 21 of the board is brought into contact with the rear face of the lower runner 4, respectively. Fix it at 22. At this time, at the same time, the back side of the board is brought into contact with each of the adhesives 17 and 18 on the front side of each intermediate board 16 to be bonded. In addition, the back surface of the abutting portion 24 between the side edges 23, 23 of each of the plasterboards 19 on the rear side is a vertically continuous shape on the front side of the vertically long intermediate board 16 at the middle part in the left-right direction of the plasterboard 5 on the front side. The adhesive 18 is placed in contact with the adhesive 18 and bonded. As a result, the joint 25 between the butts of the board side edges 23, 23
The vertically continuous adhesive 18 is used to close the area.

In the construction method of the present invention, it is also possible to modify a part of the above example of the implementation procedure as follows.

A As shown in Figure 4, the plasterboard 5 on the front side
The adhesive 13 on the back side of the abutting portion 10 between the board side edges 9, 9 is continuously applied vertically in the vertical direction. In this case, adhesive 13 is adhesive 1
1 can also be used, so the process of applying the adhesive 11 can be omitted.

B As shown in FIG. 5, each plated adhesive 13,
All of items 14, 17, and 18 are arranged vertically in a continuous manner. This makes the finished partition wall particularly strong.

C As shown in Fig. 6, each gypsum board 5...,
When the horizontal width of 19... is wide, the platter adhesive 14, the intermediate board 15, and the adhesive 17 are bonded to a plurality of locations in the middle of the front plasterboard 5... in the left-right direction.

D Each adhesive 11, 13, 14, 17, 18 is one that can be expanded and contracted according to the front and back adjustment of the plasterboards 5 and 9 before hardening, such as Yoshino Gypsum Co., Ltd.
Tiger GL Bond (trademark, whose main components are gypsum and bond) is used.

(Effects of the present invention) Since the construction method of the present invention takes the above steps, it has the following effects.

A partition wall built using this construction method has a durable double wall structure made of high steel, with both the front and rear plasterboards connected with adhesive.
The time-consuming construction of studs in the conventional method described above can be omitted, and the construction period can be significantly shortened.
Construction costs can be reduced significantly.

(b) By simply applying adhesive to the back of the butt part of the side edges of the front plasterboard, the gap between the joints between the side edges of the boards can be easily and neatly closed. Furthermore, by simply gluing the abutting portions of the side edges of the gypsum board on the rear side onto a vertically continuous adhesive, the gap between the joints between the side edges of the boards can be neatly closed without any effort.

This makes it possible to completely close the joints and sufficiently improve the sound insulation, smokeproofing, and flameproofing properties of the finished partition wall.

However, it is possible to omit the trouble of neatly filling the joints with joint compound after constructing the partition wall, and from this point of view, it is possible to further shorten the construction period and reduce construction costs.

Furthermore, since the adhesive that seals the joints adheres to the back side of the gypsum board, it does not stick to the surface of the board and stain it, giving the partition walls a beautiful appearance.
The value of high quality products increases.
