Japanese Patent No. 2905699 (paragraph 0023 column to paragraph 0028 column, FIGS. 1 and 2) Japanese Patent No. 2941663 (paragraph 0020 column to paragraph 0023 column, FIGS. 1 and 2)

  By the way, as a structure of a building, there are a conventional frame method and a frame wall method (2 × 4 method). In the building by the above-mentioned frame construction method, a suspended tree receiving material is provided, the upper mounting plate is attached thereto, and the lower mounting plate is attached to the ceiling base material on the back surface of the ceiling material.

  On the other hand, in the building by the frame wall construction method, the vertical dimension of the floor joist of the upper structure is almost equal to the vertical dimension of the frame material (surrounding material), so the upper mounting plate is directly attached to the floor joist The mounting plate is attached to the ceiling base material on the back of the ceiling material.

  In the case of the above-mentioned shaft construction method, the suspended wood receiving material is set to have a shorter vertical dimension than the floor joist in the case of the frame wall construction method. If this is made as long as the floor joist, the suspended wood receiving material that is not originally a part of the upper structure is enlarged, resulting in an increase in material costs and a reduction in cost, which is not generally adopted.

  Therefore, the vertical mounting interval of the anti-vibration suspension tree is different between the shaft assembly method and the frame wall construction method, and it is necessary to measure the height. The anti-vibration suspension tree is supported by the suspension tree support (floor joists) and the ceiling base. It takes time to attach to the material with high accuracy, and the workability is reduced due to the work on the ceiling.

  The present invention has been made in view of the above points, and the object thereof is to suspend the ceiling material accurately and easily on the upper structure regardless of whether it is a shaft construction method or a frame construction method. It is to support. Furthermore, it is providing the soundproof floor structure which can aim at the improvement of a vibration proof and a soundproof measure in combination with a vibration proof hanging tree.

  In order to achieve the above object, the present invention is characterized in that a vibration-proof hanging tree is marked and a sound insulation base material is interposed in the flooring.

  Specifically, the present invention is directed to a vibration-proof suspended tree and a soundproof floor structure, and has taken the following solutions.

  That is, the first invention relates to the former anti-vibration suspension tree, a metal upper mounting plate that is attached to the upper structure on the floor material side on the floor, and a metal that is attached to the ceiling base material on the back surface of the ceiling material on the lower floor.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
1 and 2 show a vibration-proof suspension 1 according to the first embodiment, FIGS. 3 and 4 show a soundproof floor structure of a building by a shaft construction method to which the vibration-proof suspension 1 is applied, and FIGS. 5 and 6. Indicates a soundproof floor structure of a building by a frame wall construction method (2 × 4 construction method) to which the above-mentioned vibration-proof hanging tree 1 is applied.

  First, after describing the soundproof floor structure, the vibration-proof hanging tree 1 will be described.

<Soundproof floor structure of building by frame construction method>
3 and 4, 11 is an upper structure, 12 is a beam (surrounding material) constituting the upper structure 11, and 15 is a floor material on the floor supported by the upper structure 11.

  Reference numeral 14 denotes a suspended tree receiving member arranged side by side on the upper structure 11 side below the flooring 15, and the lower end of the suspended tree receiving member 14 is located slightly above the lower end of the beam 12. doing. This is because the hanging tree receiving material 14 is not the upper structure 11, and if it is made too large, the material cost increases and the cost cannot be reduced.

  The floor material 15 is configured by laminating a floor finishing material 16, a sound insulation base material 17, and a floor base material 18 in order from the top.

  The floor finishing material 16 is shown as a single layer structure in FIG. 3, but is configured by laminating a resin decorative sheet, a base material, and a resin mat in order from the top, compared to a case where a cushion material is used. Those having moderate hardness are preferable in terms of soundproofing and walking.

The resin decorative sheet only needs to have a smooth surface. For example, a resin-impregnated paper, an olefin-based resin sheet, a polyethylene terephthalate resin sheet, or the like, or a composite of these sheets is coated on the surface of these sheets. A processed sheet-like material can be used. Moreover, when using the wooden fiber board mentioned later as a base material for the flooring 15, it is preferable to use a sheet having moisture resistance and excellent strength so that the base material is not affected by moisture.

  The said base material should just be the material which has the flexibility generally used for a flooring, for example, a synthetic resin type | system | group or a wood type woody base material can be used.

  As the synthetic resin base material, a vinyl chloride resin, a synthetic rubber resin, an olefin resin, a material in which a filler is kneaded with these resins, and the like are preferably used. As the filler, high specific gravity inorganic fillers such as calcium carbonate, barium sulfate, aluminum oxide and wood powder are suitable.

  As the wood substrate, plywood, particle board or the like can be used, but it is preferable to use a wood fiber board in consideration of the strength and flexibility of the flooring. The wood fiber board preferably has a specific gravity of 0.4 or more and 1.0 or less, and more preferably a dry-moulded medium specific gravity wood fiber board (MDF). In the MDF formed by this dry molding, the base material 3 is more likely to be divided than the low specific gravity fiber board (insulation board) and the high specific gravity wood fiber board (HDF) formed by wet papermaking. The wood fiber board preferably has a thickness of 2.0 mm or more and 3.0 mm or less. If the thickness is less than 2.0 mm, when used for a flooring material, the amount of dents due to impact from the surface side becomes large. If the thickness is larger than 3.0 mm, the flooring material 1 can be used. Since flexibility is inferior, it is not preferable.

  The resin mat is particularly necessary when a wood base material is used as the base material, and may be anything that can be backed. For example, vinyl chloride resins, urethane resins, latex resins, polyester resins, etc., modified products of these resins, or various recycled plastics can be used. This resin mat is selected and used depending on the combination in consideration of the adherability of the construction adhesive to be used. From the viewpoint of adhesion and quality stability, a vinyl chloride resin-based resin mat is preferably used. In addition, the flooring material generally used can be used besides the floor finishing material of the said multilayer structure.

  The above-mentioned sound insulation base material 17 is also shown as a single layer structure in FIG. 3, but a PP (polypropylene) plate, a low-density PE (polyethylene) short fiber nonwoven fabric, and a high-density nonwoven fabric produced by a spunbond method are on top. Are stacked in order. With this structure, a soft walking feeling with moderate elasticity can be obtained, and the cooling of the floor can be mitigated. In addition, short fibers such as PET, PP, nylon, or urethane foam may be used instead of the PE short fiber nonwoven fabric.

  The floor base material 18 is also shown as a single-layer structure in FIG. 3, but in this embodiment, an ALC (lightweight cellular concrete) panel and a structural plywood (OSB, etc.) are laminated in order from the top. ing. The floor base material may have a general structure.

  A ceiling material 19 made of gypsum board or the like is disposed below the upper structure 11 so as to be separated from the floor material 15. The ceiling material 19 has a single-layer structure in FIG. 3, but may have a two-layer stacked structure. The surface of the ceiling material 19 is finished by attaching a sound absorbing plate such as cloth or rock wool. A plurality of ceiling base materials (a field edge 20 and a field edge receiving material 21) are attached to the back surface of the ceiling material 19 at a predetermined interval. In FIG. 3, reference numeral 23 denotes a heat insulating material such as glass wool or rock wool laid on the ceiling material 19.

  The ceiling material 19 is suspended and supported on the upper structure 11 by the plurality of vibration-proof suspension trees 1. Specifically, as will be described later, the first mounting plate 2 of the anti-vibration suspension tree 1 is attached to the suspension tree receiver 14 with the nail N, and the second attachment plate 3 is attached to the field edge receiver 21 with the nail N. The ceiling member 19 is suspended and supported on the upper structure 11 by the vibration-proof suspension tree 1.

<Soundproof floor structure of building by frame wall method (2 × 4 method)>
In this soundproof floor structure, the lower end of the floor joist 13 constituting a part of the upper structure 11 and the lower end of the frame member (surrounding member) 22 are set at substantially the same height position.

  In addition, the first mounting plate 2 of the vibration-proof suspension tree 1 is attached to the floor joists 13 with the nail N, the second attachment plate 3 is attached to the field edge 20 with the nail N, and the ceiling material 19 is attached to the vibration-proof suspension tree. 1 is suspended and supported by the upper structure 11.

  The rest is the same as the above <Soundproof floor structure of building by frame construction method>, and detailed description is omitted.

<Anti-vibration suspension 1>
The anti-vibration hanging tree 1 includes a first mounting plate 2 as an upper metal mounting plate that is attached to the upper structure 11 on the floor material 15 side on the floor, and a ceiling base material (field edge holder) on the back of the ceiling material 19 on the lower floor. And a second attachment plate 3 as a metal lower attachment plate attached to the material 21 or the field edge 20).

  The first mounting plate 2 has a substantially L-shaped plate body portion 4 and an inverted T-shape that is suspended downward from the lower end of the plate body portion 4 and has locking piece portions 5b projecting on both sides of the lower end of the shaft portion 5a. Are formed integrally with the hook portion 5, and two insertion holes 4 a are formed on the upper end side of the plate body portion 4. The first mounting plate 2 is a press-formed product of a rectangular metal plate material.

  On the other hand, the second mounting plate 3 has two vertical plate portions 6 and 7 arranged vertically so that the lower end of the upper first vertical plate portion 6 and the upper end of the lower second vertical plate portion 7 are horizontally aligned. The plate portion 8 is integrally connected, and two insertion holes 7 a are also formed on the lower end side of the second vertical plate portion 7. The first vertical plate portion 6 faces a lower portion excluding its upper end portion on the front side of the plate body portion 4 of the first mounting plate 2, and a long hole 8 a is formed in the horizontal plate portion 8. The shaft portion 5a of the hook portion 5 of the first mounting plate 2 is inserted into the long hole 8a. The major diameter of the long hole 8a is set shorter than the length of the locking piece 5b of the hook portion 5. The second mounting plate 3 is also a press-formed product of a rectangular metal plate material.

  Between the middle of the plate body portion 4 of the first mounting plate 2 and the first vertical plate portion 6 of the second mounting plate 3, there is a rectangular rubber-shaped anti-vibration block 9 that connects the two together. Intervened. For example, when the vibration isolating block 9 is burned and damaged by a fire, the locking piece 5b of the hook portion 5 of the second mounting plate 3 is arranged around the long hole 8a so that the ceiling material 19 does not fall. It is designed to be locked.

  On both sides of the anti-vibration block 9, first marks 9a as upper marks for positioning with respect to the lower ends of the beams 12 which are the upper structure 11 of the ceiling material 19 are integrally projected at the time of building the building by the shaft construction method. It is installed. The first mark 9a may be provided on the first mounting plate 2.

  On the other hand, on the both sides near the upper end of the second vertical plate portion 7 of the second mounting plate 3, the lower side for positioning with respect to the lower end of the frame member 22 which is the upper structure of the ceiling member 19 when the building is constructed by the framed wall method A second mark 7b as a mark is cut out.

  When the ceiling material 19 is suspended and supported by the upper structure 11 using the vibration-proof suspension tree 1 configured as described above, the vibration-proof block 9 (first mounting plate 2) of the vibration-proof block 9 (first mounting plate 2) is used at the time of construction of the building by the shaft assembly method. The ceiling member 19 is positioned with respect to the upper structure 11 (beam 12) with reference to the first mark 9a, and the nail N is driven into the hanging tree receiving member 14 from the insertion hole 4a, and the first mounting plate 2 is moved to the hanging tree receiving member. 14 is fixed. On the other hand, when the building is constructed by the frame wall construction method, the nail N is positioned by positioning the ceiling material 19 with respect to the upper structure (frame material 22) with reference to the second mark 7b of the vibration isolation block 9 (second mounting plate 3). Is inserted into the field edge 20 from the insertion hole 7 a to fix the second mounting plate 3 to the field edge 20. In this way, one anti-vibration suspension tree 1 can be shared by the shaft assembly method and the frame wall construction method in which the vertical mounting interval of the anti-vibration suspension tree 1 is different, and the first mark 9a and the second mark 7b are By using as a reference, the ceiling material 19 can be suspended and supported on the upper structure 11 accurately and easily without taking a dimension for determining the height.

  Further, in the soundproof floor structure of the building by the frame construction method, the first mounting plate 2 is attached to the suspended wood receiving material 14 and the second mounting plate 3 is attached to the field edge 20 via the field edge receiving material 21, respectively. The vibration generated on the floor 15 side of the floor is 2 by the vibration-isolating block 9 of the vibration-isolating hanging tree 1 that suspends and supports the material 19 on the upper structure 11 and the sound insulation base material 17 interposed in the floor 15. It is possible to improve vibration and sound insulation by absorbing at a place and making it difficult to be transmitted to the ceiling material 19 below.

  Further, in the soundproof floor structure of the building by the frame wall construction method, the first mounting plate 2 is attached to the floor joist 13 and the second mounting plate 3 is attached to the field edge 20, and the ceiling material 19 is suspended from the upper structure 11. The vibration isolation block 9 of the vibration isolation suspension 1 to be supported and the sound insulation base material 17 interposed in the flooring 15 absorb the vibration generated on the flooring 15 side on the floor at two places, and the ceiling material 19 on the lower floor. Therefore, it is possible to improve vibration and sound insulation. In this soundproof floor structure, the field edge 20 is prevented from coming into contact with the locking piece 5b of the first mounting plate 2 so that the vibration on the floor is not transmitted to the field edge 20.

  Also, in the <soundproof floor structure of the building by the frame wall method (2 × 4 method)>, the soundproofing base material 17 is provided in the second embodiment in which both the vibration-proof hanging tree 1 and the soundproof base material 17 are provided. Both the lightweight floor impact sound level and the heavy floor impact sound level were superior to those of Comparative Example 2 without the swinging wood 1.

  FIG. 8 shows a configuration diagram of the sound insulation base material 17 to which floor heating measures are taken.

  The sound insulation base material 17 is a floor heating panel in which heating wires 17d are stretched. For example, synthetic resin low foam (PET, PP, PE, etc.) 17a, aluminum foil 17b, low density nonwoven fabric (PET, PP, PE, nylon, etc.) 17c, heating wire 17d, high density nonwoven fabric (PET, PP, PE, nylon, etc.) 17e, and a floor finish 16 is laminated on the synthetic resin low foam 17a.

  Therefore, if the flooring 15 using the sound insulation base material 17 is adopted, the sound insulation floor structure for floor heating can be obtained by the heating wire 17d stretched inside the sound insulation base material 17 without requiring any special construction. can do.

  In addition, you may use the anti-vibration suspension tree 1 by changing 180 degree | times to the up-down direction contrary to the above. In this case, the second mounting plate 3 becomes the upper mounting plate, the first mounting plate 2 becomes the lower mounting plate, and the second mark 7b of the second mounting plate 3 (upper mounting plate) is the upper side. In addition to being a mark, the first mark 9a on the first mounting plate 2 (lower mounting plate) side is a lower mark.
