BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a board assembly, and more particularly to a board assembly capable of improving the sound insulation performance of the wall body and the out-of-plane rigidity of the wall body. It is a thing. The present invention further relates to a partition wall structure and a partition wall construction method using such a board assembly.

2. Description of the Related Art A so-called dry-type partition wall is used as a partition wall for a building or a work in which workability and lightness are emphasized.
Widely used for practical use. A so-called frame-structured partition wall is known as a typical structure of the partition wall of the dry method, and this partition wall is generally used for vertical lightweight steel studs aligned on a wall core. , It is constructed by fixing the building boards that make up the walls on both sides.
As another type of partition wall structure, there is known a partition wall having a structure in which studs or studs are omitted and the upper and lower ends of a building board are fixed to a ceiling runner and a floor runner. This type of partition wall is generally expressed by a structural name such as a non-stud structure, a studless structure, or a ny stud structure (hereinafter simply referred to as "non-stud structure"). The structure of the partition wall of the non-stud structure is, for example, the Japanese Utility Model No. 6-100 according to the applicant's application.
No. 04 publication. According to the structure of the partition wall disclosed in the gazette, a relatively narrow gypsum board base material is fixed to the upper runner and the lower runner, the pasteboard and the interior board, through the gypsum-based adhesive, It is attached to the outer surface of the base material.

As another type of non-stud structure, a partition wall structural type using a so-called reinforcing rib board is known. In this type of non-stud structure, a so-called ribbed board having reinforcing ribs extending in the long axis direction (longitudinal direction) of the board is used as a construction board. The reinforcing rib is composed of a laminated body of a plurality of board pieces laminated in parallel on the board along the side edges in the longitudinal direction, or a bent portion obtained by bending both side edges in the longitudinal direction of the board.
When such a board with ribs is attached to the upper and lower runners of the partition wall, the reinforcing ribs extend vertically or vertically in the internal space of the partition wall at a predetermined interval in the width direction of the board. The reinforcing rib having such a form locally thickens the board, and can increase the cross-sectional modulus, bending rigidity, compressive strength, impact resistance, etc. of the board to a certain extent, and also the surface of the wall of the partition wall. The external rigidity can be improved to some extent.

[0004]

However, the partition walls of buildings in recent years are required to have higher sound insulation performance and out-of-plane rigidity. For example, as a boundary wall of an apartment or a condominium, a partition wall of the dry method is adopted from the viewpoint of weight reduction of the partition wall, while the sound insulation performance that is difficult to obtain with the partition wall of the dry method, that is, the noise of the adjacent room is completely insulated. A high level of sound insulation performance tends to be additionally required as a design condition or a construction condition. Here, regarding sound insulation performance that cuts off noise in the low frequency range, a certain degree of design conditions or requirements are satisfied by adopting a partition wall with a non-stud structure and using a relatively heavy building material. You can However, the partition wall of the non-stud structure using the board with the conventional reinforcing rib is not suitable for musical instrument sound, audio equipment or OA.
It is not possible to sufficiently block the sound emitted by the device or the like, or the sound in the relatively high frequency range such as the metallic sound. Therefore, in recent years, the requirements or design conditions for apartment houses, etc. tend to place particular emphasis on noise countermeasures or sound insulation measures in the high frequency range.
A non-stud structure or a reinforcing structure for a building board that can effectively and inexpensively solve such a condition has not been developed yet.

In addition, the heightened awareness of property in recent years, or
Due to concerns about earthquakes, the structural or construction conditions for partition walls, especially the boundary walls of condominiums such as condominiums, are becoming stricter, and it is necessary to further improve the out-of-plane rigidity of the partition wall. Has occurred. However, in the conventional partition wall structure or building board reinforcement structure,
It is difficult to achieve this type of design / construction conditions. Moreover,
In buildings that require complicated facility wiring and the like, for example, in recent intelligent buildings, there are buildings with floor heights of 4 to 5 m. However, with conventional ribbed boards, 3
It is not possible to sufficiently deal with the design of floor heights or wall heights of 4 to 4 m or more, and as a result, in the non-stud partition walls having a structure in which the wall bodies of each wall surface are basically self-supporting, There is an inevitable limit on the floor height or wall height that can be constructed due to the rigidity of the board. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a board assembly that includes a reinforcing rib and can be used as a wall body of a partition wall having a non-stud structure. In particular, it is an object of the present invention to provide a board assembly capable of improving the sound insulation performance against noise in a high frequency range and improving the out-of-plane rigidity of the wall body.

The present invention further provides a board assembly for a partition wall having a non-stud structure which can improve the proof strength and rigidity of the wall body and can increase the floor height or wall height of the partition wall which can be designed and constructed. The purpose is to do. Another object of the present invention is to provide a structure of a partition wall using the building board and a method of constructing the partition wall.

FIG. 10 is a cross-sectional view of the partition wall showing a modification of the board assembly shown in FIGS. 8 and 9, and FIG. 11 is a vertical cross-sectional view of the partition wall shown in FIG. Is.
In FIG. 10, the basic structure of the board assembly 1 including the laminate 4, the building board 2 and the fixing jig 6 is substantially the same as the basic structure of the board assembly shown in FIG. However, the board assembly 1 further comprises a second building board 9 which constitutes a second substrate, the second building board 9 being arranged relative to the central axis of the reinforcing ribs 4.
And are arranged axisymmetrically. The center axis of the reinforcing rib 4 is located on the center line of the partition wall. The second building board 9 is adhered to the side edge surface of the reinforcing rib 4 with an adhesive or an adhesive 3 except for the region where the fixing jig 6 is provided. Preferably, in order to maintain the relative position and relative angle between the second building board 9 and the reinforcing ribs 4, a fixing jig (not shown) having substantially the same configuration as the fixing jig 6 is arranged in the vertical direction. The fixing jig 6 is attached at a distance from the fixing jig 6 in a substantially symmetrical manner. Thus, the board assembly 1 as a whole forms a linear member or a rod-shaped member having an H-shaped cross section, and the board assembly 1 having such a shape is resistant to the compressive, bending and shear stresses applied to the studs. , Has an effective and sufficient section modulus and bending rigidity.

As shown in FIG. 11, the upward extension portions of the building boards 2 and 9 of the board assembly 1 are fixed to the flange portion 16 of the ceiling runner 14 by screws and / or adhesives, and the building board 2 , 9 are fixed to the flange portion 12 of the floor runner 14 by screws and / or adhesives, and the board assembly 1 extends perpendicularly to the interior area of the partition wall. The building board 2 and the second building board 9 located on both sides of the board assembly 1 face indoor spaces on both sides, respectively, and an adhesive or an adhesive material is applied to the surfaces of these boards 2 and 9. The back surface of the disposal board 26 is adhered via the interposer board 26, and the back surface of the interior base board or the makeup interior board 27 is adhered to the surface of the disposal board 26 via an adhesive or an adhesive material. As can be easily understood, in this example, the board assembly 1 is used in the same usage mode as the conventional lightweight steel stud. Although the respective embodiments described above are intended to orient the reinforcing ribs 4 vertically or vertically, it is also possible to orient the reinforcing ribs 4 horizontally or laterally. 12 and 13 show reinforcing ribs 4 in order to improve the impact resistance of the partition wall.
FIG. 3 is a perspective view and a vertical cross-sectional view of the back surface of the board assembly showing an embodiment in which the board is oriented at least horizontally.

As shown in FIG. 12, the reinforcing ribs 4 are horizontally bonded to the back surface of the building board 2, and the fixing jigs 6, 6 are provided.
Is held at a predetermined position (height) and posture. Preferably, the reinforcing rib 4 has a height H from the floor surface of about 700 m when the board assembly 1 is attached to the partition wall.
It is positioned so that it corresponds to the range from m to 1500 mm. As shown in FIG. 13, a horizontal reinforcing rib 4 and
The vertical reinforcing ribs 4 can be arranged on the back surface of the building board 2 so that the reinforcing ribs on the whole grid can be formed in the board assembly 1. In this way, the board assembly 1 having the horizontal reinforcing ribs 4 arranged within the predetermined height range from the floor surface further improves the impact resistance of the wall body against the impact acting on the partition wall. As described above, the board assembly 1 according to the present invention includes the building board 2 and the building board 2.
The reinforcing rib 4 is adhered to the back surface of the laminate in an upright state, and the fixing jig 6 for holding the posture and position of the laminated body. The reinforcing rib 4 is oriented at right angles to the building board 2. When the board assembly 1 is attached to the partition wall, the reinforcing ribs 4 increase the rigidity and strength of the wall body against short-term or long-term vertical load, horizontal load, bending load and the like that act on the wall body. Therefore, it is possible to construct a partition wall having a non-stud structure capable of supporting a floor or wall height design of 4 m or more.

Further, the reinforcing ribs 4 disperse the impact force, bending stress and shearing stress acting on the wall body, and avoid local stress concentration on the wall body, and therefore, in combination with the effect of increasing the rigidity and strength, It is possible to effectively prevent the deformation or damage of the wall body. In particular, the horizontal reinforcing ribs 4 arranged in a predetermined height range from the floor surface make the wall body resistant to impacts that may act on the wall body in a general living space or living space. It can be inexpensively and efficiently improved.
Further, the board assembly 1 provided with the reinforcing ribs 4 is
The so-called coincidence effect is not generated in the high frequency range of about 00 Hz to 4000 Hz, and the noise in the high frequency range can be effectively insulated. The coincidence effect in the high frequency range is found in the wall of the conventional board or the board with ribs and is a factor that reduces the sound insulation effect in the high frequency range. Therefore, in the conventional wall body, extremely difficult adjustments such as making the thickness of the lower sticking board and the thickness of the upper sticking board different, or adjusting the specific gravity of each board were forced. However, according to the board assembly of the present invention, the coincidence effect is prevented from occurring in the high frequency range of about 2000 Hz to 4000 Hz without the need for such complicated and irregular adjustment, and an effective wall body is provided. The sound insulation effect of can be secured.

The reason why the above-mentioned effect is obtained by the structure of the present invention is not necessarily clear, but such an effect is considered to be due to the fact that the fiber directions of the material are orthogonal to each other. That is, in the board assembly 1 of the present invention, the fiber direction of the material of the building board 2 that constitutes the substrate and the fiber direction of the material of the board piece 5 that constitutes the reinforcing rib 4 are substantially intersecting. Be oriented. Therefore, regarding the out-of-plane rigidity and impact resistance of the board assembly 1, the reinforcing ribs 4 having a fiber direction intersecting with the fiber direction of the building board 2 are provided.
However, with respect to sound insulation, such reinforcing ribs effectively disperse bending stress and the like, and shift the frequency range in which the coincidence effect occurs to a higher frequency range. As a result, 2000 Hz which is generally regarded as a problem To 4000 Hz
It is considered to prevent the occurrence of coincidence effect in a high frequency range. Further, a certain implementation product of the board assembly 1 according to the present invention (a commercially available gypsum board is used as the construction board 2 and the board piece 5) and a conventional board with reinforcing ribs (plurality of gypsum board pieces are replaced with gypsum board) A board with ribs laminated in parallel on the back surface of the substrate) and the height of the reinforcing ribs 4 (FIG. 2, W + w) were matched, and the sound insulation effect and the out-of-plane rigidity were compared. However, the board assembly 1 of the present invention is particularly suitable for high frequency range (2000H).
Excellent sound insulation performance was exhibited at z to 4000 Hz).
