Description

[Detailed explanation of the idea] The present invention relates to a water drainage structure for a soundproof door.

Soundproof doors, whose frames are filled with sound-absorbing materials such as inorganic fibers to improve sound insulation performance, use gaskets at the joints between the glass and frames to prevent fluid leakage for air and water tightness. Because it is not always possible to completely prevent leakage due to wind and rain and the pressure difference between outside air and inside air, it is necessary to drain the water that has leaked into the stile.

Hereinafter, the water drainage structure of a conventional soundproof door will be explained based on FIG. 1. FIG. 1 shows a front view of the conventional example, and 1 is a middle frame with grooves 3 formed on the top and bottom into which glass 2 is inserted; A drain hole 5 communicating with the vertical frame 4 on the knob side is bored in the upper groove 3. 6 is a lower frame having a groove 7 formed on one side into which the glass 2 is inserted;
A drain hole 8 communicating with the vertical stile 4 on the knob side is bored at the top. 9 is an upper stile, 10 is a vertical stile, and 11 is a sound absorbing material filled in the upper stile 9, the middle stile 1, the lower stile 6, and the vertical stile 10 on the hanging base side.

Incidentally, the glass 2 is fixed to each of the above-mentioned frames by gaskets (not shown).

In such a conventional example, the glass 2, the vertical stile 10, the upper stile 9, and the middle stile 1 are damaged due to wind and rain and the pressure difference between outside air and inside air.
Water that has entered between the lower stile 6 and a gasket (not shown) flows along the gasket into the drain holes 5, 8 of the middle stile 1 and the lower stile 6, and from the water drain holes 5, 8 to the knob side. It flows into the vertical stile 4 and is discharged to the outside.

However, since the water drained from the drain hole flows into the vertical stile on the knob side and then drains to the outside,
It becomes impossible to fill the inside of the vertical stile with a sound absorbing material, resulting in a drawback that the sound insulation properties of the vertical stile are deteriorated.

The purpose of the present invention is to solve the above-mentioned drawbacks. A drain hole is formed in the partition surface, and the drain holes in the upper and lower partition surfaces are connected with a drain pipe, thereby communicating the grooves formed above and below the hollow part. .

Hereinafter, one embodiment of the present invention will be described based on FIGS. 2 to 8.

In the figure, 12 is the middle stile, and 13 is the middle stile 12.
The hollow part is filled with a sound absorbing material 14 made of inorganic fiber such as glass fiber. Reference numerals 15 and 16 indicate grooves formed on the upper and lower sides of the hollow portion 13; 17 and 18 indicate upper and lower partition surfaces that partition the hollow portion 13 and the grooves 15 and 16; and 19 indicate grooves formed at both ends of the upper partition surface 17. The provided water drain hole 20 is a water drain hole formed in the lower partition surface 18 opposite to the water drain hole 19.

21 is a lower stile, and 22 is a hollow portion of the lower stile 21, which is filled with a sound absorbing material 14. 23 and 24 are grooves formed on the upper and lower sides of the hollow portion 22; 25 and 26 are upper and lower partition surfaces that partition the hollow portion 22 and the grooves 23 and 24; and 27 are holes bored at both ends of the upper partition surface 25. The provided water drain hole 28 is a water drain hole formed in the lower partition surface 26 opposite to the water drain hole 27.

Reference numeral 29 denotes a cylindrical connector fixed to the drain holes 19, 27 so as not to protrude into the upper partition surfaces 15, 25. For example, as shown in FIG. By making the drain hole 19 into an inverted truncated cone shape, a connecting tool 29 is provided on the upper partition surface 15.
may be made so that it does not protrude. 31 is a watertight packing, 32 is a connecting pipe, and one end is connected to the connecting tool 2.
9, and the other end is passed through drain holes 20, 28 formed in the lower partition surfaces 16, 26.

33 is a vertical stile on the hanging base side with grooves 34 formed on both sides, 35 is a partitioning surface that partitions the groove 34 of the vertical stile 33 and the hollow part 36, and 37 is a vertical stile on the knob side with grooves 38 formed on both sides. , 39 is a partition surface that partitions the groove 38 of the vertical stile 37 on the knob side and the hollow part 40, 41 is the upper stile, 42 is the hollow part of the upper stile 41, and 43 is a groove formed above and below the hollow part 42. and the partition surface 44
It is separated from the hollow part 42 by. 45, 46
are air pressure adjustment holes bored at both ends of the partition surface 44.

Reference numeral 47 designates a cylindrical connecting body that is attached to the air pressure adjustment hole 46, and has a locking portion 48 formed at the head and a connecting portion 49 continuous to the locking portion 48.
Reference numeral 50 denotes an air pressure adjustment pipe, one end of which is connected to the connecting portion 49 of the connecting body 47 and the other end passed through the air pressure adjustment hole 45.

In addition, instead of providing the air pressure adjustment pipe 50 in the upper stile 41, as shown in FIG. The air pressure adjustment hole 51
A connecting body 47 may be attached to the connecting body 47, and L-shaped or F-shaped pressure adjustment pipes 52, 53 may be connected to the connecting body 47 to lead to outside air.

Alternatively, an air pressure adjustment pipe in which L-shaped air pressure adjustment pipes 52 arranged vertically as shown in FIG. 7 are connected may be used.

54 and 55 are made of glass, and are fixed with a gasket 56. In addition, the upper stile 41 and the vertical stile 3
The hollow portions 42, 36, 40 of 3, 37 are filled with sound absorbing material 14, respectively. Note that the grooves 15, 34, 38, and 43 on the outer periphery of the glass 54 are in communication with each other, and will be collectively referred to as groove A hereinafter. Further, the grooves 16, 26, 38, and 43 on the outer periphery of the glass 55 are also in communication with each other, and will be collectively referred to as groove B hereinafter.

Next, to explain the operation of the above structure, due to the pressure difference between the wind and rain or outside air and the inside of the grooves A and B, the gap between the gasket 56 and the glass 54, the upper stile 41, the middle stile 12, and the vertical stile 33, 37 The water that has entered from the stile 12 passes through the connecting pipe 32 through the drain hole 19 drilled in the upper partition surface 17 of the middle stile 12, and passes through the gasket 56, the glass 55,
Middle stile 12, lower stile 21, vertical stile 33, and vertical stile 37
Flows into the drain hole 27 of the lower stile 21 together with the water that enters from between the drain hole 27 and the connecting pipe 32.
Exhaust to the outside through the soundproof door.

In addition, since one end of the pressure adjustment pipe 50 and the drain pipe 32 provided in the lower stile 21 are led to the outside air, they work to eliminate the pressure difference between the air pressure in the grooves A and B and the outside air pressure. Groove A due to pressure difference,
Prevent water from entering B.

As described above, according to the water drainage structure of the soundproof door according to the present invention, drainage holes are provided in the upper and lower partition surfaces, respectively, which partition the hollow parts of the middle and lower stile and the grooves formed above and below them. By drilling holes and connecting the drain holes on the upper and lower partition surfaces with a drain pipe, water that has entered the soundproof door due to wind and rain or the pressure difference between outside air and inside air can be removed from the drain pipe. Since water is drained to the outside of the soundproof door through the stile, each hollow part of the upper stile, middle stile, lower stile, and vertical stile can be filled with sound absorbing material, which has the effect of improving sound insulation performance compared to conventional methods. There is.

In addition, the soundproof door has drainage structures on the hanging base side and knob side, which has the significant effect of improving the drainage function.
