Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interior board mounting structure and method for attaching an interior board to a construction surface such as a wall surface or a ceiling surface with an adhesive.

[0002]

2. Description of the Related Art Conventionally, when an interior board such as a gypsum board is adhered to the inside of an RC-structured boundary wall or an outer wall, for example, a case of a boundary wall is shown in FIG. Direct bonding method in which a gypsum-based adhesive 2 is applied in the form of a dumpling on the wall surface 1a in a dotted state, and the gypsum board 3 is pressed onto the dumpling-shaped adhesive 2 as shown in FIG. (GL method) is often used. In this case, the gypsum board 3 is fixed to the adhesive 2 while floating from the wall surface 1a,
A space 4 is provided between the gypsum board 3 and the wall surface 1a.

[0003] This direct pasting method has a number of advantages, for example, since the gypsum board 3 is pasted by crushing the dumpling-shaped adhesive material 2, it can be constructed without trouble even if the wall surface 1 a is uneven. The construction period can be shortened. Further, a base frame for attaching the gypsum board 3 is not required, and the space L occupied by the base frame can be eliminated and the depth L from the wall surface 1a to the finished surface of the gypsum board 3 can be reduced.
Can be minimized.

However, in such a direct bonding method, the gypsum board 3 is bonded and attached at points, so that the gypsum board 3 is supported in a bendable manner between the bonding points. Is prone to bending vibration. That is, the gypsum board 3 easily causes a resonance phenomenon (coincidence effect) with respect to a sound source such as a living sound in the building, and a resonance phenomenon in which the bending vibration of the gypsum board 3 resonates with the air layer of the space 4 also occurs. It is known that the sound insulation performance is lower than the performance before the interior as shown in FIG. 3 due to the influence of the coincidence effect and the resonance phenomenon.

FIG. 3 is a graph showing the sound transmission loss (dB) on the vertical axis and the 1/3 octave band center frequency (Hz) on the horizontal axis. The broken line in the figure is the sound transmission loss of the bare wall on which the gypsum board is not constructed, and the solid line shown by the broken line is the sound transmission loss of the wall on which the gypsum board is constructed by the direct bonding method. Comparing these diagrams,
In the 250 Hz band, a sound insulation performance reduction area α (shaded area) due to the resonance phenomenon appears, and in the 4 KHz band, a sound insulation performance reduced area β (shaded area) due to the coincidence effect appears.

[0006] Such a phenomenon that the sound insulation performance is deteriorated is caused not only when the wall 1 is directly pasted but also when the outer wall 5 of the building is directly pasted as shown in FIG. Also occurs similarly. That is, in this case, the sound that is emitted from the sound source P in one room R1 defined with the boundary wall 6 interposed therebetween and propagates through the outer wall 5 passes through the gypsum board 3 that is stuck to the outer wall 5 by the direct sticking method. As a result, it is side-propagated to the other room R2 with a coincidence effect and a resonance phenomenon, and is re-emitted.

As described above, the direct pasting method has many advantages, but has a disadvantage of low sound insulation performance. To compensate for the low sound insulation performance, it is conceivable to adopt the method shown in FIGS.

That is, in FIG. 5A, a board having different vibration characteristics, for example, a plywood 7 is laminated on the back side of the gypsum board 3 to increase the rigidity of the gypsum board 3 and suppress resonance. Further, in FIG. 2B, glass wool 8 serving as a vibration isolator is attached to absorb vibration transmitted to the gypsum board 3. In FIG. 6, the entire back side of the gypsum board 3 is stuck to the adhesive 2 applied to the wall surface 1a in a planar manner without being applied by the direct pasting method, thereby preventing the vibration of the gypsum board 3. And eliminate the resonance space.

[0009]

However, FIG.
In the type in which the plywood 7 and the glass wool 8 are laminated and pasted as shown in FIG. 5A and FIG. 5B, the gypsum board 3 itself can be easily cut by a cutter, but the plywood 7 and the glass wool 8 which are laminated and pasted together. In this case, cutting with a cutter becomes extremely difficult, and in addition to the increase in the weight of the gypsum board 3 itself due to overlapping, the workability is greatly deteriorated.

In addition, in the case of the entire-surface type of the plaster board 3 shown in FIG. 6, the step of applying the adhesive 2 to the entire surface of the wall surface 1a becomes complicated, and the unevenness of the wall surface 1a hinders the construction. In addition, an extra finishing step is required for the wall surface 1a, which necessitates a longer construction period and a rise in construction costs.

In order to increase the rigidity of the gypsum board 3 and suppress bending vibrations, it is conceivable to attach an angle member to the back side of the gypsum board 3 although not shown. In this case, since it is necessary to match the positional relationship between the adhesive material 2 applied in a dot shape and the angle material,
Further, there is a problem that the workability is reduced.

The present invention has been made in view of such a conventional problem, and provides an inexpensive interior board mounting structure and a mounting method capable of improving the sound insulation performance of an interior board attached to a wall surface. The purpose is to:

[0013]

According to the present invention, there is provided an interior board mounting structure for mounting an interior board on a construction surface thereof, wherein the interior board is provided with a corrugated board. It is characterized by being attached to a surface. Here, the corrugated cardboard refers to, for example, paper formed by integrally attaching flat cardboard to both sides or one side of corrugated cardboard.

According to the present invention, since the cardboard is interposed between the interior board and the construction surface, the vibration is absorbed by the cushioning property of the cardboard, the sound transmitted by the interior board is reduced, and the sound insulation effect is reduced. Can be enhanced. In particular, by using inexpensive corrugated cardboard, which was not previously considered for use as a sound insulation and vibration isolation material,
Material costs can be significantly reduced.

[0015] The method of mounting an interior board according to the present invention is characterized in that the interior board is attached to the construction surface via cardboard. That is, since the corrugated cardboard is light, it can be easily handled at the time of construction, and processing such as cutting can be easily performed using a cutter or the like, so that the workability is improved and the construction cost can be reduced.

It is preferable that the cardboard is adhered to the back side of the interior board, an adhesive is applied to the construction surface, and the cardboard is pressed against the adhesive. That is, when pressing the cardboard against the construction surface side,
Due to the large bending rigidity of the cardboard, the interior board to which the cardboard is attached is not partially bent, and a flat finished surface can be easily formed by simply pressing. Furthermore, even if there is unevenness in the construction surface, the corrugated cardboard is pressed, so that the adhesive spreads easily and firmly between the corrugated cardboard and the construction surface so as to level out the unevenness, and the interior board is easily and firmly formed. Can be fixed.

Further, since the interior board attached by this method has the cardboard attached thereto, the bending rigidity of the interior board is increased, and resonance and bending vibration which causes resonance are reduced. For this reason, it is possible to reduce the coincidence effect and resonance phenomenon of the vibration propagating on the construction surface and improve the sound insulation performance. If a laminated interior board in which cardboard is integrally adhered to the back side of the interior board is used, there is no need to overlap the interior board and the cardboard while aligning them at the time of construction, so that the workability can be greatly improved.

[0018]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is an essential part cross-sectional view showing an embodiment of a mounting structure and a mounting method of an interior board according to the present invention, in which a gypsum board is mounted on an outer wall.

The method for mounting the interior board according to the present invention is as follows.
A laminated gypsum board 16 is previously formed by pasting a well-known corrugated cardboard 12 integrally on the entire back side 10a of the gypsum board 10 forming the interior board with an adhesive. Next, outer wall 1
A gypsum-based adhesive 13 is applied in a scattered manner on a construction surface 14a in which a heat insulating material 14 made of foamed urethane is adhered to the wall surface 11a of the first unit. Then, the laminated gypsum board 16 is fixed to the outer wall 11 by pressing the laminated gypsum board 16 against the construction surface 14 a so that the corrugated cardboard 12 side contacts the dumpling-shaped gypsum-based adhesive 13. Here, the gypsum board 10 used in the present embodiment is formed using gypsum as a main raw material, and has properties of being lightweight and easy to cut. Further, the cardboard 12 is placed between two flat sheets of cardboard.
It is bonded together with a corrugated cardboard interposed, and is formed by pasting a flat sheet with the top of each wave and cushioning due to the space formed by the corrugated cardboard. And a high bending rigidity due to the plurality of tubular portions.

That is, in the mounting structure of the interior board, a corrugated cardboard 12 is lined on the back surface 10a of the gypsum board 10,
It is fixed by a gypsum-based adhesive material 13 which is piled up and applied on a construction surface 14a in which a heat insulating material 14 is attached to a wall surface 11a of the outer wall 11, and a space is provided between the construction surface 14a and the corrugated cardboard 12. A part 15 is provided.

Therefore, according to the present embodiment, the construction surface 14
By pressing the laminated gypsum board 16 on the a side, the dumpling-shaped gypsum-based adhesive 13 is pressed, and the laminated gypsum board 16 is pressed.
While spreading between the cardboard 12 and the heat insulating material 14, the unevenness of the construction surface 14a can be corrected, and the interior side wall surface formed by the gypsum board 10 can be finished flat.

Further, the laminated gypsum board 16 stuck via the gypsum-based adhesive 13 is a back side of the gypsum board 10.
Since the strength of the cardboard 12 bonded to Oa is added, the bending rigidity is higher than that of the gypsum board 10 alone, and the bending vibration can be reduced. Therefore, resonance of the gypsum board 10 with the sound propagating through the outer wall 11 can be reduced, and resonance between the gypsum board 10 and the air layer between the gypsum board 10 and the wall surface 11a is also reduced. In this case, the sound insulation performance can be improved. Further, the vibration is absorbed by the cushioning property of the corrugated cardboard 12 and the propagation of the vibration by the gypsum board 10 can be suppressed, so that high sound insulation performance can be obtained.

Incidentally, since the cardboard 12 is paper, even if it is a laminated gypsum board 16 laminated on the gypsum board 10, the entire weight is light and the processing such as cutting is easy. Can be processed. Therefore, the corrugated cardboard 12 not only simply improves the bending rigidity of the gypsum board 10, but also has excellent workability and is widely available on the market, so that it is inexpensive and extremely easy to obtain.

Further, in the present embodiment, the case where the gypsum board 10 with the corrugated cardboard 12 is stuck by the direct sticking method is shown, and the gypsum-based adhesive 13 is applied in a dumpling shape. Adhesive material without limitation to the bonding method 1
Of course, the present invention can also be applied to a case where 3 is applied to the entire surface of the wall surface 11a, and the cardboard 12 attached to the gypsum board 10 is attached thereto. Further cardboard 12
May be attached to the construction surface first, and then the gypsum board 10 may be attached to the cardboard 12. Further, the adhesive is not limited to the gypsum-based adhesive 13, and other adhesives that can secure a high bonding force between the cardboard 12 and the construction surface 14a can also be used.

[0025]

As described above, in the mounting structure of the interior board according to the present invention, the vibration is absorbed by the cushioning property of the cardboard interposed between the interior board and the construction surface, and the sound insulation effect is enhanced. By using inexpensive corrugated cardboard as the sound insulation / vibration-proof material, material costs can be significantly reduced.

According to the method for mounting an interior board of the present invention,
Since the cardboard interposed between the interior board and the construction surface is light and has good workability, the workability is improved and the construction cost can be reduced.

When the cardboard is pasted on the interior board and the cardboard is pressed against the adhesive applied to the construction surface, the interior board does not bend partially due to the large bending rigidity of the cardboard, and is simply pressed. Alone, a flat finished surface can be easily formed. Furthermore, even if there is unevenness in the construction surface, the adhesive spreads in the gap between the corrugated cardboard and the construction surface so as to level the irregularity, and the interior board can be easily and firmly fixed.

In the interior board mounted by this method, the bending rigidity of the interior board is increased, and resonance and bending vibration which causes resonance are reduced. Therefore, a coincidence effect of the vibration propagating on the construction surface is obtained. And the resonance phenomenon can be reduced, and the sound insulation performance can be improved. If a laminated interior board in which cardboard is integrally attached to the back side of the interior board is used for mounting the interior board, workability is greatly improved.
