Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soundproof floor panel and a structure for mounting it between floor beams.

[0002]

2. Description of the Related Art In the case of a floor of a detached wooden framed house, especially a flooring floor, a heavy impact sound generated when bouncing upstairs may be offensive to a person living below. With the diversification of individual living times, the need to eliminate such heavy impact noise is increasing.

In a conventional wooden framed house, a flooring floor is laid via a base material provided on a floor beam. As such a base material, for example, the following soundproof floor panels are known.

As shown in FIGS. 9 (a) and 9 (b), this soundproof floor panel 30 has two sets of frame members 32 and 33 provided between two face members 31 having the same shape. It will be. From the viewpoint of workability and cost efficiency, generally, a wood material is mainly used as a constituent material of the soundproof floor panel 30. Further, conventionally, a mounting structure has been adopted in which lower surfaces of both end portions of the soundproof floor panel 30 are supported on upper surfaces of a pair of floor beams 34, and a fixing tool 35 such as a nail or a screw is struck on the supported portion. .

The soundproof floor panel 30 includes a floor beam 34.
Since it is arranged between the joists 36 provided in parallel with, the thickness is usually about the same as the thickness of the joists 36 (specifically, the thickness on the floor beam 34).

[0006]

However, the conventional soundproof floor panel 30 and its mounting structure have the following problems.

For example, when it is desired to prioritize ensuring soundproofness,
It is necessary to increase the rigidity of the entire soundproof floor panel 30 by making it thick. However, if such a configuration is adopted, the distance between the upper surface of the floor beam 34 and the lower surface of the flooring floor 37 will increase as the soundproof floor panel 30 becomes thicker. As a result, the living space on the floor becomes narrow (that is, the distance from the floor 37 to the ceiling is short).

In addition, when it is desired to secure the living space,
On the contrary, it is necessary to make the soundproof floor panel 30 itself thin to reduce the distance between the upper surface of the floor beam 34 and the lower surface of the flooring floor 37. However, if such a configuration is adopted, the soundproofness is impaired, and the effect of reducing the weight impact sound is weakened. That is, conventionally, it has been difficult to achieve the two conflicting purposes of improving soundproofing and securing a living space.

As means for achieving the above two objects, for example, a metal plate such as an aluminum plate or the like is used in place of the face material 31 made of a wood material, or a honeycomb structure is arranged between the face materials 31. Measures such as installation may be considered. However, such a configuration causes a new problem of high cost.

The present invention has been made in view of the above circumstances, and a first object of the present invention is to avoid high cost.
It aims to improve soundproofing and secure a large living space on the upper floor. A second object of the present invention is to improve the workability when mounting the soundproof floor panel on the floor beam.

[0011]

In order to solve the above-mentioned problems, in the invention described in claim 1, it is mounted on a floor beam and at least one set of frame members is provided between two face members. A soundproof floor panel consisting of, the height of which is less than or equal to the vertical thickness of the floor beams, and the width of which is less than or equal to the width between adjacent floor beams, at least on one side of the soundproof floor panel. The main point is a soundproof floor panel provided in one place.

According to a second aspect of the present invention, there is provided a structure in which a soundproof floor panel having at least one set of frame members provided between two face members is mounted between floor beams, and the height of the floor beams is equal to that of the floor beams. Provide a protrusion having a thickness equal to or less than the thickness in the vertical direction and a width that is equal to or less than the width between adjacent floor beams at at least one location on one side of the soundproof floor panel, and drop the protrusion between adjacent floor beams. Then, the gist is the mounting structure of the soundproof floor panel in which the lower surfaces of both end portions of the soundproof floor panel are supported on the upper surfaces of both floor beams.

According to a third aspect of the present invention, there is provided a structure in which a soundproof floor panel having at least one set of frame members provided between two face members is attached between floor beams, and the height of the floor beams is equal to that of the floor beams. A protrusion having a thickness not greater than the vertical thickness and a width not greater than the width between adjacent floor beams is provided at least at one location on one side of the soundproof floor panel, and a notch is provided on each of the adjacent floor beams. The main point of the structure is to mount the soundproof floor panel in which the convex portions are dropped between the adjacent floor beams so that both the notches support the lower surfaces of both ends of the soundproof floor panel.

[0014]

According to the invention described in claims 1 to 3, since the width of the convex portion of the soundproof floor panel is less than the width between the adjacent floor beams,
By lowering the convex portions between the floor beams, the lower surfaces of both end portions of the soundproof floor panel can be supported by the upper surfaces of the floor beams or the notches. With this configuration, since the portion provided with the convex portion becomes thick, the rigidity of the soundproof floor panel is increased as a whole. On the other hand, since the portion supported on the floor beam is not thick, the distance between the upper surface of the floor beam and the lower surface of the floor becomes small.

Particularly, in the invention according to claim 3 in which the notch is provided as the support portion, the amount of the soundproof floor panel protruding from the upper surface of the floor beam is reduced, so that the upper surface of the floor beam and the lower surface of the floor are reduced. The distance between and becomes smaller.

【Example】

[First Embodiment] A first embodiment of the present invention will now be described in detail with reference to FIGS.

First, the soundproof floor panel P1 in this embodiment.
The configuration of will be described. As shown in FIGS. 1A to 1C, the soundproof floor panel P1 having a substantially square shape.
Is basically two face materials 1 and 2 and a set of four frame materials 3
It is composed of one crosspiece 4 and two closing members 5.

In this embodiment, structural plywood (first grade, thickness 5.5 mm) is used as the face materials 1 and 2. The outer dimensions of the face material 1 arranged on the upper surface side are 909 mm × 909 mm
Is. The outside dimension of the face material 2 arranged on the lower surface side is 909 mm, which is slightly smaller than that of the face material 2 arranged on the upper surface side.
× 801 mm.

The face member 1 arranged on the upper surface side is fixed in a state of being slightly displaced from each frame member 3. Therefore, a so-called actual structure is formed at two locations on the upper surface side of the soundproof floor panel P1.

The wooden timber used for the four frame members 3 has a length of 909 mm and a cross-sectional dimension of 139 mm × 3.
It is 0 mm. These frame members 3 are arranged in parallel with each other between the face members 1 and 2 at equal intervals,
Moreover, it is fixed to the face materials 1 and 2 with an adhesive.

The wooden timber used for the crosspiece 4 has a length of 909 mm and a cross-sectional dimension of 139 mm × 30 mm. The crosspiece 4 as described above is provided so as to be orthogonal to each frame member 3 between the face materials 1 and 2, and is fixed to the face materials 1 and 2 with an adhesive. In addition,
Notches (not shown) are provided at positions where the crosspiece 4 and the two inner frame members 3 intersect. Hereinafter, for convenience of description, the direction in which the frame member 3 extends is referred to as the "vertical direction" of the soundproof floor panel P1, and the direction in which the crosspiece 4 extends is referred to as the "lateral direction" of the soundproof floor panel P1.

Further, the closing member 5 is arranged between the pair of frame members 3 at both ends of the frame member 3. As the closing member 5, a square member made of the same material as the frame member 3 and the crosspiece 4 is used. As a result of the provision of the blocking member 5 as described above, a semi-enclosed space is formed in the soundproof floor panel P1.

Stepped notches 6 are formed at both ends of each frame member 3, respectively. The shape of the portion cut out when forming the cutout portion 6 is a rectangular shape, and the size thereof is 70 mm × 33 mm. Therefore, the upper half portions of both end portions of each frame member 3 are vertically extended from the outer surface of the closing member 5 by 3
The ear portion 3a is projected by about 0 mm.

When the soundproof floor panel P1 is viewed as a whole, it should be understood that the lower surface of the soundproof floor panel P1 is provided with a projection 7 having the same outer shape as that of the face material 2. You can As shown in FIG. 1C, the height h of the convex portion 7 is set to be equal to or less than the vertical thickness L2 of the floor beam 8. Further, the width of the convex portion 7 (more specifically, the width in the vertical direction of the soundproof floor panel P1) w is less than or equal to the width L1 between the adjacent floor beams 8 (more specifically, between the facing side surfaces of the floor beam 8). It is set. In the soundproof floor panel P1 of this embodiment, specifically, h = 70 mm, w = 801 mm, L1 = 8.
It is 05mm and L2 = 210mm.

In the soundproof floor panel P1, the ear 3
Thickness of the central part where a is not formed (that is, maximum thickness)
The value of t becomes 150 mm. On the other hand, the thickness of both end portions where the ear portions 3a are formed (that is, the minimum thickness t−h represented by t−h).
h) becomes 80 mm. Therefore, the value of t / (t-h), which is the ratio of maximum thickness / minimum thickness, is about 1.9.

When the constitution as in this embodiment is adopted by using each of the above-mentioned materials, it is desired that the above-mentioned respective numerical values satisfy the following several relations. First of all, the value of the height h of the convex portion 7 is set to 100 mm or less, preferably 30 mm to 10 mm.
It is set to 0 mm, particularly preferably 50 mm to 80 mm. This is because if the height h of the convex portion 7 is too large, the tip of the convex portion 7 may protrude below the floor beam 8 and it may be difficult to construct the soundproof floor panel P1. However, the fact that the number of parts dropped between the floor beams 8 increases leads to an improvement in the rigidity of the frame assembly and the floor assembly. On the other hand, if the height h of the convex portion 7 is extremely small, the convex portion 7 cannot be sufficiently dropped between the floor beams 8. As a result, it becomes necessary to position the soundproof floor panel P1 in the horizontal direction, which may require extra labor and time for construction.

Secondly, the value of the maximum thickness t is 80 mm to 200 mm.
mm, preferably 100 mm to 180 mm, particularly preferably 100 mm to 150 mm. If the maximum thickness t is too small, the soundproof floor panel P1 cannot have sufficient rigidity, and the effect of absorbing heavy impact sound cannot be sufficiently obtained. On the other hand, the maximum thickness t
If the value is too large, the soundproof floor panel P1 becomes thick and heavy as a whole, although the rigidity is secured.

Thirdly, the value of the minimum thickness t-h is 50 mm to 1
It is set to 10 mm, preferably 53 mm to 100 mm, and particularly preferably 57 mm to 80 mm. Minimum thickness t
If the value of -h is too small, the rigidity of the ears 3a particularly decreases, so that when the soundproof floor panel P1 is attached between the floor beams 8, the ears 3a are likely to be damaged. on the other hand,
If the minimum thickness t-h is too large, the soundproof floor panel P1
This is because the distance between the upper surface of the floor beam 8 and the lower surface of the floor becomes large and the living space on the upper floor becomes narrower.

Next, the procedure for attaching the soundproof floor panel P1 will be described. In Figure 2, the first floor of a wooden house, 2
A floor beam 8, a pillar 9 and a body difference 10 which constitute a frame set or a floor set in the floor portion are shown. As shown in the figure, the floor beams 8 and the body differences 10 are assembled in substantially the same horizontal plane along the same direction and at equal intervals.

As shown in FIGS. 1 (c) and 2, the soundproof floor panel P1 is bridged over both floor beams 8 so that the projections 7 are dropped between the adjacent floor beams 8. At that time, the vertical direction of the soundproof floor panel P1 and the direction of the floor beam 8 are made orthogonal to each other.
Then, the lower surfaces of both end portions of the soundproof floor panel P1 are supported on the upper surfaces of both floor beams 8, specifically, the lower surfaces of the ears 3a are supported on the upper surfaces of both floor beams 8, and the frame member 3 serves as a joist. Will also serve. The soundproof floor panels P1 are laid so that their actual structures overlap each other.

After arranging the soundproof floor panel P1 as described above, the screws 11 as fixing tools are inserted through the screw holes provided in advance at both ends of the frame member 3 of the soundproof floor panel P1 and the screws 11 are tightened. In this embodiment, a screw 11 having a length of 120 mm is used.

When the soundproof floor panel P1 is fixed, as shown in FIG.
As shown in (c), a slight clearance CL is formed between the side surface of the convex portion 7 and the side surface of the floor beam 8. The clearance CL is 0 mm to 10 mm, preferably 0 mm to 5 mm,
Particularly preferably, it is about 0 mm to 3 mm. When the clearance CL is small, the soundproof property is improved, but it becomes difficult to drop the convex portion 7 between the floor beams 8 and the workability may be deteriorated. On the other hand, when the clearance CL is large, there is no problem with dropping the convex portion 7 between the floor beams 8, but the soundproofing may be deteriorated. In this embodiment, since the width L1 between the floor beams 8 is 805 mm and the width w of the convex portion 7 is 801 mm, the clearance CL is 2 mm.

The clearance CL is closed by hitting a wedge 12 from the downstairs side, as shown in FIG. 1 (c). The flooring floor 13 is laid on the upper surface of the soundproof floor panel P1 thus mounted via an adhesive layer (not shown).

Now, according to the soundproof floor panel P1 and its mounting structure of this embodiment, the convex portion 7 of the soundproof floor panel P1 is used.
Is designed to be smaller than the width L1 between the adjacent floor beams 8 by several mm. Therefore, the protrusions 7 can be dropped between the floor beams 8 so that the plurality of ears 3a at both ends of the soundproof floor panel P1 can be reliably supported on the upper surfaces of the floor beams 8. With this structure, the convex portion 7
Since the portion provided with is thick, the rigidity of the soundproof floor panel P1 can be increased as a whole. As a result, the effect of absorbing the heavy impact sound is enhanced, and the soundproofing between the upper floor and the lower floor is surely improved. On the other hand, since the ears 3a supported on the floor beam 8 do not become thick, the distance between the upper surface of the floor beam 8 and the lower surface of the flooring floor 13 can be reduced. Therefore, unlike the conventional case, it becomes possible to secure a wide living space on the upper floor.

Further, according to the present embodiment, the soundproof floor is used even though the wood materials are used as the respective constituent materials (that is, the face materials 1 and 2, the frame material 3, the crosspiece 4 and the closing material 5). Panel P
The desired rigidity is secured in 1. Therefore, unlike a conventional product that uses a metal plate, a honeycomb structure, or the like to improve soundproofness, cost reduction and weight reduction can be reliably achieved.
And by making the soundproof floor panel P1 lighter,
The advantage is that workability is also improved.

Further, in the soundproof floor panel P1, the thickness (that is, the minimum thickness t-h) of the ear portion 3a where the screw 11 is inserted is smaller than the total thickness (that is, the maximum thickness t). Is also quite thin. Therefore, the screws 11 used need only be relatively short. Therefore, as compared with the conventional configuration in which the use of long screws is obligatory, the work of tightening the screws 11 is also simplified. Further, when the soundproof floor panel P1 is bridged, the projection 7 is dropped so that the soundproof floor panel P1 can be positioned at the same time. Also from the above points, the soundproof floor panel P1 is excellent in workability.

Next, the results of comparing the rigidity (N · m ² / m) of each soundproof floor panel when the structure similar to that of the soundproof floor panel P1 of Example 1 was adopted are shown in the table of FIG. 3 as reference data. Shown in. In the table, the test specimens of ,, and are similar in construction to the soundproof floor panel P1 of the first embodiment. ，
The test body of is a conventional example. The dimensions and the like of each test body are as shown in the table, and the items that are not particularly described are common. As is clear from this table, the rigidity of the comparative example is the highest, followed by the highest. Assuming that the rigidity value is 100 and the relative ratio is taken, 8
It can be seen that the value is considerably higher than 0%. According to the table, it is suggested that the rigidity tends to increase when the clearance CL decreases or when the thickness of the ear portion 3a increases. By the way, even if there is the clearance CL, it is possible to bring the relative ratio close to 100 by closing it with, for example, the wedge 12. [Embodiment 2] Next, the soundproof floor panel P2 of Embodiment 2 and its mounting structure will be described with reference to FIGS.
The difference will be mainly described.

As shown in FIGS. 4 (a) to 4 (c), the soundproof floor panel P2 of Example 2 basically comprises two face members 1 and 2 and a set of two frame members. 3 and 1 crosspiece 4 and 2
It is composed of one outer blocking member 21 and two inner blocking members 22. That is, the outer blocking member 21 and the inner blocking member 22 are used instead of the six blocking members 5,
The main difference from Example 1 is that the number of frame members 3 is two.

The outer blocking member 21 is provided between the facing ears 3a. The inner blocking member 22 is provided immediately inside the outer blocking member 21. A wooden material is used for the outer blocking member 21 and the inner blocking member 22. Then, the outer blocking member 21 and the inner blocking member 22 as described above.
As a result, the soundproof floor panel P2 forms a closed space that is shielded from the outside space. Since the shapes and dimensions of the face materials 1 and 2 and the frame material 3 are not particularly changed, the outer shape and dimensions of the entire soundproof floor panel P2 are also the same as those in the first embodiment.
It is basically equal to that of. Further, in the case of this soundproof floor panel P2 having the same basic structure, since it can be mounted between the floor beams 8 according to the first embodiment, detailed description thereof will be omitted.

It is apparent that the soundproof floor panel P2 and its mounting structure of this embodiment can also obtain the same effects as those of the first embodiment. That is, it is possible to improve soundproofing and to secure a large living space on the upper floor while avoiding cost increase. Further, the workability of the soundproof floor panel P2 is improved by reducing the weight and improving the positioning.

In particular, when the soundproof floor panel P2 of this embodiment is attached, not only the lower surface of the ear portion 3a but also the lower surface of the outer blocking member 21 is supported by the upper surface of the floor beam 8. Therefore, the load applied to the ear portion 3a is applied to the outer blocking member 21.
And the ears 3a are thinned and are less likely to be damaged. Therefore, it is convenient as a structure for securing a large living space on the upper floor. Further, with this configuration, the lower surfaces of both end portions of the soundproof floor panel P2 are continuously in contact with the upper surface of the floor beam 8. Therefore, the sound propagation path between the upstairs and the downstairs is almost completely cut off, resulting in an improvement in soundproofing. Furthermore, this soundproof floor panel P2 is convenient for construction because the screw 11 can be inserted into a portion other than the ear 3a. [Third Embodiment] Next, a soundproof floor panel P3 and its mounting structure of a third embodiment will be described with reference to FIGS.
The difference will be mainly described.

As shown in FIGS. 6 (a) to 6 (c), the soundproof floor panel P3 of Example 3 is basically composed of two face members 1 and 2 and a set of two frame members. 3 and one crosspiece 4. That is, the main difference is that the half-closed space does not exist because the blocking member 5 is omitted, and that the number of the frame members 3 is less than two. Further, since there is no portion corresponding to the ear portion 3a, the overall shape (particularly the size of the convex portion 7) is different.

In this embodiment, unlike the first embodiment, the notches 6 are not formed at both ends of the frame member 3. Instead, on the upper surface side of the floor beam 8, a notch portion 24 corresponding thereto is formed. By the way, in the soundproof floor panel P3, specifically, the dimension of each part is h =
5.5mm, w = 801mm, L1 = 805mm, L2 = 21
It is 0 mm.

Next, the procedure for attaching the soundproof floor panel P3 will be described. As shown in FIGS. 6 (c) and 7, the soundproof floor panel P3 has a convex portion 7 between the adjacent floor beams 8.
Is laid down and bridged over both floor beams 8. Then, the soundproof floor panel P is formed on the upper surface 24a of the cutout portion of both floor beams 8.
The lower surface of both end portions of 3 (that is, the supported portion 23 where the face material 2 is not provided) is supported. The soundproof floor panel P3 arranged as described above is fixed by the screws 11 inserted into the screw holes at both ends of the frame member 3. In this embodiment, a screw 11 having a length of 200 mm is used. Then, the flooring floor 13 is laid on the upper surface of the soundproof floor panel P3 via an adhesive layer (not shown).

Now, even in the soundproof floor panel P3 and its mounting structure of this embodiment, since the basic structure is common to that of the first embodiment, it is clear that the same operational effect can be obtained. That is, it is possible to improve soundproofing and to secure a large living space on the upper floor while avoiding cost increase. Further, the workability of the soundproof floor panel P3 is improved by reducing the weight and improving the positioning.

Particularly, in this embodiment, the floor beam 8 is used as a supporting portion.
Since the notch 24 is provided in the floor beam 8, the amount of the soundproof floor panel P3 protruding from the upper surface of the floor beam 8 can be reduced. Therefore, the distance between the upper surface of the floor beam 8 and the lower surface of the flooring floor 13 can be reduced.

Further, in the case of this soundproof floor panel P3, since the floor beam 8 is provided with the notch 24 in advance, the positioning is easy and the construction is labor-free. Further, since the soundproof floor panel P3 has a simple structure, it is easy to manufacture and is cost effective. [Fourth Embodiment] Next, a soundproof floor panel P4 and its mounting structure of a fourth embodiment will be described with reference to FIG.

As shown in FIGS. 8 (a) to 8 (c), the soundproof floor panel P4 of the fourth embodiment includes glass wool 26 having a thickness of 25 mm as a sound absorbing material in the soundproof floor panel P1 of the first embodiment. Is provided. Further, a large number of communication holes 27 are provided in the face material 2 which is the lower side surface. The presence of these communication holes 27 constitutes a so-called Helmholtz resonator in the soundproof floor panel P4.

Specifically, the diameter of the communication hole 27 is 3.
It is set to 5 mm, and the Helmholtz resonator is set to a relatively low frequency range (resonance frequency f ₀ = 100 Hz). The above points are the differences from the first embodiment. In addition,
Since the shape and size of each part are not particularly changed, the outer shape and size of the entire soundproof floor panel P4 are the same as those of the first embodiment. However, a sealed space is formed by using the six closing members 5. Further, the mounting procedure is also the same as that in the first embodiment, and therefore the description is omitted here.

It is obvious that the soundproof floor panel P4 and its mounting structure of this embodiment can also obtain the same operational effect as that of the first embodiment. In particular, in the case of the configuration of the present embodiment, the weight impact sound in the low frequency range is canceled by the Helmholtz resonator described above, so that more excellent soundproofing is secured.

The present invention is not limited to the above embodiment, but can be modified as follows.
For example, (a) The number of frame members 3 is 2 as in Examples 1 to 4.
It does not have to be a set or a set of four. For example, by increasing the number of frame members 3 to 5 or more, the soundproof floor panels P1 ...
It is also possible to secure the rigidity of P4 as a whole. Further, for the same reason, the crosspiece 4 may be two or more.

(B) Between the pair of face members 1 and 2 of the soundproof floor panels P1 to P4, a brace corresponding to a striking beam may be further provided. That is, higher rigidity is secured by providing non-parallel braces in both the frame member 3 and the cross member 4. In this case, for example, there is an advantage that the soundproof floor panels P1 to P4 can be attached without providing the striking beam even in the place where the striking beam should be disposed in the floor assembly.

(C) The convex portion 7 is formed on the soundproof floor panel P1 to P4.
Two or more locations may be provided on the lower surface side of the. In this case, there is an advantage that the number of installed soundproof floor panels P1 to P4 can be small.

(D) Of course, both the notch 6 on the frame member 3 side and the notch 24 on the floor beam 8 side may be provided. (E) In the fourth embodiment, instead of the glass wool 26, for example, a structure in which rock wool, polyurethane foam or the like is arranged may be adopted. Of course, the resonance frequency f ₀ can be set to 100H by appropriately changing the diameter of the communication hole 27 and the like.
It may be set to a value other than z.

(F) The face materials 1 and 2 are not limited to the structural plywood used in Examples 1 to 4.
For example, various boards such as a particle board, a structural panel, a hard board, a gypsum board, and a sheathing board may be used. Among these, structural plywood is relatively excellent in terms of lightness and strength.

(G) The clearance CL may be filled with a hard resin. With such a resin, the conformability to the clearance CL is good, and the clearance C
There is a merit that L is surely filled.
