[0010]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the accompanying drawings.
1 to 3 show an embodiment of a soundproof wooden floor structure of an apartment according to the present invention.
Reference numeral 1 denotes a structure such as a condominium room or a corridor, which is generally made of a concrete slab. The structure is generally surveyed prior to construction, and the level is adjusted by applying mortar on the surface. However, even if the level is adjusted by setting the thickness of the buffer member itself, which will be described later. Good.
[0011]
Reference numeral 2 denotes a sound insulation sheet attached to the entire surface of the structure surface 101 whose level has been adjusted.
Reference numeral 3 denotes a grounding group provided on the sound insulating sheet 2, and a shock absorbing member 7 made of a sound insulating elastic material such as rubber disposed on the sound insulating sheet 2 at a predetermined interval, for example, 250 to 500 mm, and the shock absorbing members The joists 8 and 7 are arranged in rows and have a mat-like soundproof material 9 that is closely packed between the joists. The joists 8 extend in the Y direction and the X direction, and these “Y direction and X direction” include cases where the floor has an appropriate slope depending on the shape of the floor.
[0012]
The position of the joists 8 in each row is fixed by a band-shaped pressing member 10 mainly composed of a sound insulating elastic material. Further, in order to eliminate a partial thickness increase due to the attachment of the presser member 10, a level adjustment strip 11 made of a sound insulating elastic material is formed on the joist upper surface exposed between the presser members 10 and 10. Thus, the upper surface of the soundproof material 9 and the upper surface of the pressing member 10 are flush with each other.
[0013]
Reference numeral 4 is a plywood / artificial wooden panel, and the base plate laid on the upper surface of the base set 3, 5 is a sound insulating sheet attached in close contact with the base plate 4, and 6 is applied on the sound insulating sheet 5. Desired wooden flooring.
[0014]
The soundproofing wooden floor according to the present invention, when expressed in different terms, is a sound insulating sheet layer, a joist row group supported by a cushioning member, and a base layer composed of a soundproofing material filled between the joist rows, It is comprised from the multilayer structure of the baseplate layer spread | overlaid, the sound insulation sheet layer which covers a baseplate layer, and the wooden flooring layer affixed on this.
[0015]
4-11 has shown in steps the example of the construction method of a soundproof type wooden floor structure, and, roughly, a sound-insulation sheet sticking process, a grounding process, a baseplate sticking process, a soundproofing sheet sticking process, and It consists of a wooden flooring process. In this example, the direction in which the wooden flooring is pasted is the X direction.
In a normal case, the structure level adjustment is performed to adjust the state of the existing structure in the part where the wooden flooring is installed to a level according to the work content. The existing structure 1 is generally a concrete slab, but the level varies depending on the accuracy of construction and the slab's slab, so that the level is equalized with cement-based or resin-based mortar, etc. Secure slopes and step surfaces. However, when the construction area is small, the level adjustment may be performed by adjusting the thickness of the buffer member in the base assembly process described later.
[0016]
[Sound insulation sheet pasting process]
This process is performed to obtain the final soundproofing effect to the lower floor of the residual sound that has been reduced by the soundproofing effect by the upper layer (underlying layer layer + underlying plate layer + sound insulation sheet layer). For example, a sound insulation sheet 2 having a length of 1.0 to 1.2 mm is used, and as shown in FIG. 4, the entire wooden flooring target range and the rising portions 1 a and 1 a near the wall are covered in a bag shape. The united sound insulation sheet 2 has a flat mating portion that has a predetermined overlap width and is bonded with a sound insulation tape 200 having an adhesive surface. The direction at this time is preferably a direction intersecting the joist row (X direction in this example) in order to make the joist level uniform.
The rising part 2 'at the wall secures a sufficient rising dimension to the extent that there is no problem in finishing the wall, and this is also affixed to the base of the wall with a sound insulating tape.
Thus, the state shown in FIG. 4 is obtained.
[0017]
[Background assembly process]
This process is shown in FIGS. 5 to 8 and is a characteristic and important process in the present invention, which reliably absorbs the life-generating sound directly applied to the wooden flooring and does not transmit the vibration to the structure unit 1. The purpose is to secure a ground structure that enables safe and reliable installation of an important part of the living space such as the floor, while preventing reverberation due to air vibrations.
[0018]
The materials used in this step are the buffer member 7, the joist 8, the presser member 10, the level adjustment strip 11, and the soundproof material 9.
The buffer material 7 uses a rubber material such as a 90 mm square and a thickness of 1 to 4 mm, for example, and is arranged in a grid shape at intervals of 250 to 500 mm on the sound insulating sheet 2 as shown in FIG.
[0019]
The joists 8 are arranged in a straight line on the buffer members 7 and 7 having such an arrangement. In this example, they are arranged in the X direction. The joist 8 is a beam or a skeleton member that stably fixes a wooden flooring and supports a load applied to the flooring, and is obtained by cutting plywood or artificial wood. As dimensions, for example, the width is 90 mm and the height is 24 mm, and the joist 8 is supported by the buffer member 7 on the lower surface. The buffer member 7 supports the joist 8 while preventing vibration and sound from being directly transmitted from the joist 8 to the structure 1.
The buffer member 7 is prepared in several thicknesses, or the height on the sound insulation sheet 2 is changed by stacking standard thicknesses, so that the level can be adjusted at the same time. it can. That is, the buffer member 7 also serves as a level adjusting material.
[0020]
In this way, each joist row that is configured is fixed by the presser member 10 so that the position does not shift. The holding member 10 preferably has soundproofing properties such as rubber, and in this example, a band body 10a and an attachment member 10b for fixing the band body 10a to the structure 1 are used. The attachment member 10b may be an adhesive, but in this example, a concrete nail paired with a washer is used.
[0021]
The band 10a can be easily obtained by, for example, cutting a rubber band wound in a roll shape having a width of 90 mm and a thickness of 2 mm. The length of the band 10a is assumed to be a joist width + twice the joist thickness + twice the length attached to the sound insulating sheet.
The belt body 10a is pressed from the upper part of the joist 8 at a certain length, for example, at the position of every other buffer member 7, and pressed from the upper part of the joist 8, as shown in FIG. 6 (a). It bends so as to bend and bends from a position in contact with the sound insulation sheet 2 to form seats 100 and 100, and the seats 100 and 100 are fixed to the structure 1 with the attachment member 10b.
[0022]
Thereby, the position of each joist row is firmly fixed at predetermined intervals. Moreover, when the joist is directly fixed to the housing with a nail or bolt, vibration is transmitted to the housing through the nail or bolt, but a seat is formed with a sound insulating material and indirectly attached by the mounting member 10b applied thereto. Since the attachment is performed, the vibration is blocked by the band 10a and is not transmitted to other parts.
[0023]
As described above, when each joist row is fixed, the level of the upper part of the joist 8 becomes uneven by the thickness of the strip. Therefore, the level adjusting strip 11 is disposed on the upper surface of the joist 8 between the strips 10a, 10a. If necessary, lightly adhere to the upper surface of the joist 8 with an adhesive. The level adjustment strip 11 is simple because it is only necessary to cut the same material as the strip 10a to a predetermined length.
As a result, the joists 8 in each joist row are in contact with the sound-insulating cushioning material 7 and the upper surfaces are also in contact with the sound-insulating belt 10a and the level adjustment strip 11, so to speak, they are sandwiched by the sound-insulating material. Transmission is greatly reduced. In addition, since the entire upper surface is covered with the band 10a having the same thickness and the level adjustment strip 11, the upper surface level is uniform without unevenness.
The cord C such as an electric wire or a telephone line can be freely wired by cutting the joists 8 and 8 to provide a gap as shown in FIG.
[0024]
Since the above operation results in the state of FIG. 7, the soundproof material 9 is then filled. When the base plate 4 is pasted directly on the joist row, and the wooden flooring 6 is pasted, the cavity between the joist rows under the base plate 4 is sent to the lower floor in the same way as the drum part of the drum. Since the phenomenon of expansion is caused, the soundproof material 9 is filled in order to prevent the phenomenon and to improve the heat insulation performance of the floor at the same time.
[0025]
The soundproofing material 9 may be any known material, for example, a rock wool mat, a glass wool mat, or the like having a thickness of about 20 to 30 mm is used, and is filled between the joist rows as shown in FIG. . Although fixing and adhesion are not required, the soundproofing material 9 is filled without a gap so that the lower surface of the soundproofing material 9 is in contact with the sound insulating sheet 2 and the upper surface matches the level of the band body 10a and the level adjusting strip 11. FIG. 9 shows a state where the soundproofing material filling process is completed.
[0026]
[Underlaying process]
This step is performed in order to hold down the base set 3 from above and to obtain a stable and reliable fixing of the wooden flooring.
As the material, for example, a 900 × 1800 × 12 mm plywood or an artificial wooden panel is used, and the base plate 4 is spread in close contact with the base set 3 and fixed to the joists 8 with fixing brackets such as screw nails and wood screws. The fixing metal must not reach the structure 1 and has a length that does not exceed the total of the buffer member 7 + joist 8 + strip 10 a + base plate 4. FIG. 10 shows the completed state of this process.
[0027]
[Sound insulation sheet pasting process]
This step is performed in order to insulate the sound generated in the life directly given to the wooden flooring 6 in the vicinity of the generation source so that the lower soundproof structure functions more effectively.
The sound insulation sheet 5 may be the same as the sound insulation sheet 2 used in the previous sound insulation sheet sticking step, or may be less accurate depending on the required sound insulation performance.
It is preferable that the method of application is completely spread over the construction area, not overlaid, but cut with a sharp blade from the top of the overlap to remove excess, butt cuts, and a piece of cloth tape with no thickness. The rising part connected to the wall should be raised enough to prevent the wall finishing, and fixed with a baseboard. FIG. 11 shows the state after this process. Since the sound insulating sheet 5 serves as an intervening layer that prevents the base plate 4 and the wooden flooring 6 from coming into direct contact with each other, the sound insulating effect is higher than installing a sound insulating sheet under the base plate 4.
[0028]
[Wooden flooring pasting process]
This step is the final step, and the wooden flooring 6 to be used is not limited and is not limited to any material such as firewood or cedar. However, it is preferably a sufficient drying material, and a complete plate or three layers are combined. A plate or the like is generally used. A dimension is arbitrary, for example, a 12-30 mm thing is used, and it arranges so that a joist row may be orthogonal.
The soundproof wooden floor shown in FIGS. 1 to 3 is completed through the above steps.
[0029]
The above soundproof wooden floor structure and construction method are merely examples, and the present invention is not limited thereto.
1) The shock-absorbing member 7 is not necessarily a small piece, but may be a belt-like member that supports the entire lower surface of the joist 8. In this case, no gap is generated between the sound insulating sheet 2 and the surface.
[0030]
2) Although the buffer member 7 is a separate member separated in the above embodiment, it may be a unit or assembly that is joined to the bottom surface of the joist 8 at predetermined intervals in advance as shown in FIG. In this case, the distribution work of the buffer member 7 can be omitted, and if the joist 8 is arranged on the sound insulating sheet 2, the joist row supported by the buffer member 7 can be obtained immediately.
[0031]
3) The pressing member is not limited to being a band. That is, like the pressing member 10 ′ in FIG. 12B, the upper surface portion 102 that presses the upper surface of the joist 8, the side surface portions 103 and 103 that press the side surface of the joist 8, and the seat portions 100 and 100 that are set on the sound insulating sheet 2. It may be a molded body having.
In the case of this mode, with the joists 8 arranged, the upper and side surfaces of joists 8 are positioned by covering the joists 8 with the pressing members 10 ′ at predetermined intervals, and the seat 100 contacts the sound insulation sheet 2. Therefore, it can be constructed by a simple operation of simply fixing the seat portion 100 with an attachment member (metal fitting or adhesive).
[0032]
4) The pressing member may be integrated with the buffer member. FIG. 13 shows this example. The pressing member 10 ″ includes an upper surface portion 102 that presses the upper surface of the joist 8, side surfaces 103 and 103 that press the side surface of the joist 8, and a seat portion 100 that is placed on the sound insulating sheet 2. In addition to 100, a lower surface portion 70 as a buffer member is integrally formed, and a window hole 104 corresponding to the cross-sectional shape of the joist 8 is defined by the upper surface portion 102, the side surface portions 103 and 103, and the lower surface portion 70. Yes.
FIG. 13A shows the upper surface portion 102, the side surface portions 103 and 103, and the lower surface portion 70 having the same thickness, FIG. 13B shows the lower surface portion 70 having a larger thickness, and FIG. 13C shows the lower surface portion 70. And the thing which enlarged the thickness of the seat part 100 is shown.
[0033]
In the case of this mode, the joist 8 is inserted into the window hole 104 and the seat portion 100 is fixed, and the joist 8 is sandwiched between the lower surface portion 70 as a cushioning material and the upper surface portion 102 as a pressing member. Therefore, workability is very good and efficiency can be achieved.
As a technique, the presser member 10 ″ may be arranged on the sound insulating sheet 2 in advance, and the joist 8 may be inserted into the window hole 104 in that state, or the joist 8 may be inserted into the plurality of presser members 10 ″ first. The assembly may be made by sequentially inserting through the window holes 104, and the assembly may be arranged on the sound insulating sheet 2 and fixed.
[0034]
[Effect of the embodiment]
The wooden floor of the present invention stably supports the base plate 4 using the joists 8, and the wooden flooring 6 is pasted thereon, so that domestic wood and local wood can be used depending on the interior design and taste preferences. It can be freely selected and used, and can be constructed using conventional methods. Therefore, domestic and local timber can be used for all interiors of condominiums, increasing the amount of use and revitalizing forestry. In addition, natural materials such as Muku's timber make it possible to specify a healthy housing for an apartment.
The wooden flooring 6 is supported by the base plate 4 at its entire lower surface, and the base plate 4 is supported by joists 8 at every required interval, and is also applied to the mat-like soundproofing material 9 filled at the same level between the joist rows. Because it touches, there is no fluffy feeling.
In the present invention, since the foundation set 3 including the joists 8 is provided, the foundation of the partition wall can be used by using the skeleton structure of the foundation set 3, and the degree of freedom of arrangement of the room and the partition can be increased. Moreover, since the soundproofing material 9 has heat insulation properties, the heat insulation performance of the floor can be enhanced.
In addition, since no adhesives are used, or even if they are used, there is no adverse effect on the human body due to harmful components.
[0035]
As for soundproofing, the sound and vibration given to the wooden flooring 6 are weakened by the sound insulation sheet 5 directly below the base plate 4, and the base plate 4 is a soundproof belt of the pressing member 10 of the base set 3. 10a or the upper surface portion 102 and the level adjustment strip 11 are supported by the joists 8, so that the sound and vibration of the base plate 4 are not transmitted to the joists 8, and the soundproofing material 9 is closely spaced between the joists. Since it is filled, it is absorbed, not transmitted in the horizontal direction, and no reverberation is generated. Further, the joists 8 are not directly supported but indirectly supported by the buffer member 7 or the lower surface portion 70 on the side of the structure portion, so that they are not transmitted downward, and residual sound is not transmitted to the buffer members 7, 7 or the lower surface portion 70. The sound insulation sheet 2 attached between the structure surfaces is finally cut off.
Therefore, excellent soundproofing can be realized while the finished thickness from the surface of the wooden flooring to the structure is as thin as about 50 to 60 mm.
[0036]
Specific examples and results of performance experiments are shown below.
(1) Experimental equipment:
An upper and lower open box made of 20 mm foamed polystyrene on the outside of a cubic cylinder made of 24-ply plywood and having an inner dimension of 900 mm was created. A 900 × 900 × 20 mm plate was installed at a position 600 mm below the upper part of the box, and concrete was cast 100 mm thick on the upper part to provide an existing structural surface of the simulated apartment. And
The upper part of the concrete is a virtual living space, and the lower part is a virtual living space below the floor.
(2) Measuring method:
The following five types of wooden soundproof floors are installed on the existing structural surface of the simulated condominium, and golf balls (high-temperature impact sounds) and softballs (low-impact impact sounds) are dropped from the same height, and 500 mm from the concrete top surface. The sound volume was measured with a noise meter (LA 1240 manufactured by Ono Sokki) installed below.
[0037]
(3) Type Comparison Example of Wooden Soundproof Floor 1: Comparative Example 2: Remaining Concrete Body, Placed Floor Construction Method (System Construction Method 2), Total Thickness 95mm.
Comparative Example 3: Soundproof sheet (1 mm) + propellant with soundproof and vibration-proof rubber feet (100 mm) + soundproof material (100 mm) + base plate (12 mm) + plywood flooring (15 mm), total thickness 128 mm.
[0038]
Comparative Example 4: Sound insulation sheet (1 mm) + underground assembly (30 mm) + soundproof sheet (1 mm) + underground plate (12 mm) + Mugboard flooring (15 mm), total thickness 59 mm.
The foundation set is the same as that of the present invention described later.
The present invention: sound insulating sheet (1 mm) + underlying group (30 mm) + underlying board (12 mm) + soundproofing sheet (1 mm) ++ muffled board flooring (15 mm), total thickness 59 mm.
The foundation set employed the aspect of the first embodiment. That is, a joist row was composed of a rubber cushioning member + joist + a presser member made of rubber strip and a rubber strip, and a rock wool mat was filled between the joists.
[0039]
The volume was measured three times, and the average value was obtained. A value when the falling object is a golf ball is defined as an A value (dB), and a value when the falling object is a soft ball is defined as a B value (dB).
In Comparative Example 1, the A value was 83.08 and the B value was 81.49.
In Comparative Example 2, the A value was 73.12 and the B value was 75.08.
In Comparative Example 3, the A value was 74.79 and the B value was 76.84.
In Comparative Example 4, the A value was 76.39 and the B value was 75.24.
In the present invention, the A value was 71.86 and the B value was 74.23.
[0040]
As is clear from this result, it can be seen that the wooden floor of the present invention has a very good soundproofing performance despite its thin thickness.
[0041]
【The invention's effect】
According to claim 1 of the present invention described above, the finished surface of the wooden flooring can be secured with a thin thickness of about 50 to 60 mm from the structure, and the sound insulation base is disposed on the sound insulation sheet 2 and the sound insulation sheet.
