[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for preventing rain noise of a sash, and more particularly to a take-out type sash.

[0002]

2. Description of the Related Art As shown in FIG. 6, in a sash 1 having a framed glass shoji 2, especially when the sash 1 is attached to an opening of a building wall 3 in a so-called take-out mode, the sash 1 is located outside the building outside wall. The rainwater that has transmitted along the outer wall surface during rainfall forms water droplets 8 on the upper frame 5 of the sash 1 or the lower edge 7 of the upper frame 6 of the shoji screen. (Filling) Directly hits the exposed surface of 10 to generate vibrations, resulting in rain noise. Similarly, even when rainwater stays on the packing 10 and the water film 11 is formed, when the water droplet 8 collides with the water film 11, vibration is generated, and a rain sound is generated. The term "filling material" refers to a fixed sealing material, a caulking material, a packing material, and the like used in a glass fitting groove for the purpose of watertightness and airtightness.

According to an experiment, a frame constituting the sash 1,
Most of the frame and the glass have a frequency component close to the peak frequency of the rain sound, and among them, the vibration of the lower frame 9 and the face material 12 is larger than those of other parts. Eventually, the vibration that becomes a rain sound propagates from the lower frame 9 of the main source to the entire glass 12 and sash frame 13, and propagates from the indoor exposed surface 14 of the sash 1 to the room. Such a rain sound becomes noise depending on the environment, and causes damage such as disturbed sleep and reduced concentration to humans in the room.

SUMMARY OF THE INVENTION The object of the present invention is to reduce rain noise in a sash having a framed glass shoji.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a sash having a framed glass shoji. A vibration damping material is provided so as to cover at least the outdoor exposed surface of the filler between the lower frame and the glass of the frame set. The damping material may be an outwardly inclined surface extending from the surface of the glass to the edge of the lower frame. Furthermore, the interior exposed surface of the lower frame may be covered with a vibration damping material.

[0006]

[Function] At least, cover the exposed surface of the filling material of the lower frame.
The provided vibration damping material absorbs the collision energy of the falling water drops and prevents the vibration from being transmitted to the indoor side. When the surface of the vibration damping material is formed on an inclined surface, a water film is prevented from being formed on the surface, energy of water droplets colliding with the surface is released from above in the outdoor direction, and collision energy received by the lower frame is reduced. Smaller. The vibration damping material covering the indoor exposed surface of the lower frame is located between the indoor surface of the lower frame and the indoor air, and absorbs vibration that is transmitted from the lower frame to the indoor air.

1 shows a sash 1 provided with a framed glass shoji 2 and glass is an example of a face material. The same members as those in the above-described conventional example are denoted by the same reference numerals, and detailed description will be omitted. A sash 13 is fitted into and fixed to the opening of the building wall 3 in a take-out mode, and the sash frame 13 is composed of an upper frame 5, a lower frame 15, and left and right vertical frames (not shown). Are attached in a slip. The framed glass shoji 2 has a glass 12 inside a framed frame composed of an upper frame 6, a lower frame 9, and left and right vertical frames (not shown).
Are mounted, and the four surroundings on the front and back thereof are fixed with packings (one of the fillings) 10. In addition, the lower frame 9 has a multi- hollow structure in which a space normally provided is further partitioned by a middle partition 9 '.

The upper outdoor packing 10a (filling material) is covered with silicone on its exposed surface (lower surface).
A normal sealing material 16a made of PVC or the like is provided. This is provided by means of sandwiching or sticking with an adhesive. In addition , this sealing material 1
6a is an exposed surface of the outdoor packing 10a as shown in FIG.
In addition to the above, it is provided so as to cover the outdoor side edge portion 21 of the upper frame 6.
The glass 12 has an outwardly inclined surface extending from the outer surface of the glass 12 to the outdoor edge 4 of the upper frame 6. In other words, the sloped surface of the upper frame 6 is set so that the outdoor side is high and the glass side is low.
The inclined surface 17 extends from the edge 7 to the glass surface.
Also, on the exposed surface (upper surface) of the lower outdoor packing 10b ,
A seal member 16b of a vibration damping material is provided to cover this by the same means as described above. However, this sealing material 16
b is formed of a rubber-based or asphalt-based flexible damping material. The vibration damping material is a material having a high efficiency of converting vibration energy into heat energy by internal friction. In this embodiment, the sealing material 16b is
The outside edge 21 of the frame 9 is also covered. Therefore,
The sealing member 16b is formed as an inclined surface from the outer surface of the glass 12 to the outdoor edge 21 of the lower frame 9 in the same manner as described above, and is formed as an outward inclined surface 18 having a lower outdoor side and a higher glass side. Further, the indoor side exposed surface 14 of the lower frame 9 has a thickness of 1.
A rubber-based vibration damping material (sile sheet NP..., Trade name) 19 having a thickness of about 5 mm is adhered and coated using a double-sided tape. Reference numeral 20 denotes an aluminum plate, which is adhered to the indoor side surface of the vibration damping material 19 to make up this portion. The aluminum plate 20 has a thickness of about 1.0 mm.

Sealing members 16c and 16d are also provided on the exposed surfaces of the upper and lower packings 10c and 10d on the indoor side, and are inwardly symmetric with the sealing members 16a and 16b on the outdoor side and the glass 12 therebetween. An inclined surface is formed. This is to make the design uniform in design, and a normal sealing material is used.

With the above structure, in the event of rainfall, water droplets 8 fall from the outdoor edge 4 of the upper frame 5 and the lower edge 7 of the upper frame 6 to the outwardly inclined surface 18 of the sealing material 16b in the lower frame 9 of the shoji 2. Falls. However, most of the energy of the falling water drops 8 is absorbed by the sealing material 16b, which is a vibration damping material, and is directed to the outside by the inclined surface 18, so that the energy for vibrating the lower frame 9 is as follows. It is slight. For this reason, the rain sound is actually eliminated. In this case, as in this embodiment, if the lower frame 9 has a multi- hollow structure, the lower frame 9 itself has a high efficiency of absorbing vibration, so that the rain noise can be more effectively reduced. The outside edge 21 of the lower frame 9 is controlled.
When covered with the sealing material 16b, which is a vibration material,
It can absorb the impact of rainwater. Outside edge of lower frame 9
This is effective when 21 is wide.

Further, conventionally, the packing 1 in the lower frame 9 is used.
The rainwater, which tends to stay on the exposed surface of the outer surface 0b, is formed on the outwardly inclined surface 1 where the sealing material 16b has a lower outdoor side and a higher glass side.
8 so that it is quickly discharged and does not form a water film. Therefore, no rain sound is generated when the falling water droplet 8 collides with the water film.

Further, the outwardly inclined surface 17 of the sealing material 16a on the outdoor side in the upper frame 6 is inclined so that the outdoor side is high and the glass side is low, so that water drops at the lower edge 7 of the upper frame 6. The rainwater to be swiftly guided to the glass surface to prevent the generation of the water droplet 8 itself. For this reason, the amount of rain water that reaches the outdoor side surface of the upper frame 6 along the outdoor side surface of the building wall 3 and the upper frame 5 and falls to the lower frame 9 as water drops 8 is extremely small. Incidentally, fallen water drops from the lower edge of the bottom rail 9 is also on the lower frame 15, it is possible to collide with the water film on the lower frame 15, a small drop under distance of the water droplet, little rain occurs.

The height h1 (FIG. 2) of the inclined surface 18 with respect to the sealing material 16b made of the vibration damping material on the outdoor side in the lower frame 9 is variously changed, and the magnitude of the rain sound (noise) due to the water droplet 8 in each case. 10m from the indoor side of lower frame 9
When the inspection is performed at a position m away, the noise level becomes as shown in FIG. 3, and the noise level decreases as the seal height h1 increases.
That is, the height h of the outwardly inclined surface 18 of the sealing material 16b.
1 is preferably as large as possible. However, if the height is too high, the lighting area of the glass 12 is reduced, and the edge of the glass 12 becomes heavy, so care must be taken.

Similarly, as shown in FIG.
The height h2 of the inclined surface 17 of the outdoor seal 16a was also investigated. According to this, it can be understood that the rain noise (noise level) decreases as the seal height h2 increases, but the effect is remarkable up to about h2 = 10 mm.

FIG. 5 shows the relationship between the thickness of the damping material 19 provided on the indoor side surface of the lower frame 9 and the rain sound (noise level). That is, it is effective to attenuate the vibration damping material 19 on the indoor side surface in order to attenuate the vibration from the indoor side surface of the lower frame 9, and it is understood that the thickness is suitably about 1.5 mm. In addition, FIG. 5 is a numerical value when the aluminum plate 20 for makeup is adhered, and is a measured value in the indoor side space of 10 mm and 1000 mm from the surface of the aluminum plate 20.

The above is an embodiment, and the present invention is not limited to the illustrated specific configuration. The framed glass shoji 2 is not limited to being pulled over the sash frame, but may be of another type such as a protruding type or a fitting type. As for the sealing material 16 provided on the exposed surface of the packing 10, if at least the outside of the lower frame 9 is used as a vibration damping material, there is an effect of reducing rain noise. Furthermore, even if the above-mentioned inclined surface is not formed in the sealing material 16 provided between the lower frame and the glass of the framed glass shoji 2, there is an effect of reducing rain noise. Occurrence of vibration due to water droplets
The most effective is to stick the damping material 19 on the indoor side of the lower frame 9, and this part alone is sufficient,
Other areas or the entire area of the indoor side surface of the sash 1 may be covered with the damping material 19. The method of coating the vibration damping material 19 is not limited to the double-sided tape, but may be adhesion, painting, or the like.
