Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of installing a sound insulation base material used for improving sound insulation performance of a floor.

[0002]

2. Description of the Related Art FIG. 9 is a perspective view showing a conventional method of installing a sound insulation base material on a floor. This method is called a low-floor sound insulation floor construction method, and in a factory, a damping steel plate 23 (composite material in which rubber or viscoelastic resin is sandwiched between steel plates) formed in a keystone plate shape is used. The support column 21 with the free cushion rubber 20 is attached, and the damping steel plate 23 is laid on the floor where sound is to be insulated. The sound-insulating floor is completed by laying a siding plate 9 and a surface plate 10 on the vibration-damping steel plate 23. The floor constructed by this method actually has effective sound insulation due to the vibration damping steel plate 23 and the free cushion rubber 20.

[0003]

However, even in the low floor type sound insulation floor construction method as described above, when the sound insulation base material such as the vibration-damping steel plate 23 is provided, the distance from the existing floor surface to the new floor surface is about 15c.
It had a height of about m. Therefore, the existing method of installing the sound insulating base material may not be used in some existing buildings having a particularly low height from the floor to the ceiling, and a new method has been desired.

The present invention has been made in order to solve the above-mentioned problems, and it is necessary to install a sound insulation base material so that it can be applied to existing buildings having a low height from the floor to the ceiling. It is an object of the present invention to provide a method of installing a sound insulation base material on a floor that minimizes the height.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a step of manufacturing a sound insulating base material by attaching a connecting material to a floor to a bottom portion of a vibration damping steel plate formed into a predetermined shape, and setting a reference height on the floor. ,
A step of arranging height correction materials at multiple points on the floor required to horizontally install the sound insulation base material, and a height correction material for making these locations the same as the reference height, and a connecting material for the sound insulation base material when installing the sound insulation base material A step of installing mortar at multiple points on the floor opposite to, and a step of installing a sound insulation base material on the height correction material before the mortar solidifies, and solidifying the mortar to fix the sound insulation base material and the floor It is equipped with and.

[0006]

According to the method of the present invention, the new floor surface is higher than the existing floor surface by the height of the damping steel plate formed into a predetermined shape, the thickness of the tie material and the height of the height correcting material. .. As a result, the required height from the existing floor surface to the new floor surface can be reduced to 1/3 that of the conventional technology.
It can be about 1/6.

EXAMPLES Next, examples of the present invention will be described with reference to FIGS. 1 is a plan view showing one step of the embodiment of the present invention, FIG. 2 is a front view of FIG. 1, FIG. 3 is a plan view showing one step of the embodiment of the present invention, and FIG. 4 is an embodiment of the present invention. 5 is a front view showing one step of an example of the present invention, FIG. 5 is a front view showing one step of an example of the present invention, FIG. is there.

First, a fastener 3 is provided with an expanded metal 2 as a connecting material to a concrete floor on the bottom of a vibration damping steel plate 1 formed into a keystone plate by roll forming or the like.
Install with. In this embodiment, the plate-like rubber 4 is sandwiched between the bottom of the vibration damping steel plate 1 and the expanded metal 2 to further enhance the vibration damping capacity by the vibration damping steel plate 1, the rubber 4 and the expanded metal 2. It constitutes a sound insulation base material (Figs. 1 and 2). The height H (height from the bottom surface of the expanded metal 2 to the top surface of the vibration damping steel plate 1) of the sound insulating base material is about 2.5 cm for the purpose of the present invention, and the width and the length are set arbitrarily. You may.

On the other hand, the concrete floor 5 is marked 6 with a reference position for installing the sound-insulating base material (FIG. 3).
This is to determine the position on the concrete floor 5 where the expanded metal 2 of the sound insulation base material is to be located.

Further, the level of the concrete floor 5 is measured and a point serving as a reference of the height of the concrete floor 5 is set. And when installing sound insulation base material Expanded metal 2
At a position that is to be opposed to, and is a position necessary to keep the sound insulation base material horizontal, a height correction material 7 for setting these positions to the reference height previously set is installed ( 4 and 5). The height correcting material 7 may be made of metal or wood and does not need to be fixed to the concrete floor 5.

Next, in order to secure the strength and rigidity of the expanded metal 2 at a position on the concrete floor 5 that faces the expanded metal 2 and between the height correction members 7 previously installed. The mortar 8 is installed at required intervals (Figs. 4 and 5). Since the mortar 8 is for fixing the sound insulation base material and the concrete floor 5, a relatively hard kneading material is used so as not to flow out, and the mortar 8 is set higher than the reference height set previously. Further, the mortar 8 may be installed in any place other than the above, if necessary.

Next, before the mortar 8 is solidified, a sound insulation base material is installed on the concrete floor 5 so that the expanded metal 2 is located on the height correcting material 7 (FIG. 6). At this time, since the mortar 8 exceeds the standard height,
Expanded metal 2 is difficult to put in mortar 8. As a result, the mortar 8 is solidified, so that the sound insulation base material is fixed to the concrete floor 5.

In order to complete the floor, a siding board 9 (if necessary) and a surface board 10 may be attached on the sound insulation base material fixed to the concrete floor 5 (FIG. 7).

Although the damping steel plate is formed into a keystone plate shape in the above-mentioned embodiment, the other parts are shown in FIG.
You may shape in a shape like (b). Further, the tie material is not limited to the expanded metal, but may be a steel plate or the like having unevenness for improving the integration with the mortar. The concrete for the concrete floor includes ordinary concrete, lightweight concrete, and lightweight cellular concrete.

[0015]

EFFECTS OF THE INVENTION According to the method of the present invention, the installation of the sound insulation base material using the height correcting material and the mortar makes it possible to construct a sound insulation floor in which the height from the existing floor surface to the new floor surface is remarkably lowered. It became possible. The method of the present invention can be applied to both new construction and remodeling, but is particularly effective in remodeling existing buildings having a low floor-to-ceiling height.
