Description

  The present invention relates to a ventilation sound insulation door that ensures air permeability inside and outside the door and that also provides sound insulation properties.

  In recent years, detached houses are obliged to ensure ventilation performance of living rooms in order to prevent sick house syndrome caused by harmful substances such as formaldehyde. In order to make the indoor door that separates the living room and the non-living room function as a ventilation path, an undercut part is formed at the lower part of the door. Ventilation is through. However, by ensuring air permeability, the sound insulation, which is another function of the door, is sacrificed.

  In order to eliminate such drawbacks, Patent Document 1 discloses a sound insulating door in which openings are formed in lower portions of both the front and back surfaces of the door, and communication paths are formed on the inside of the door so as to communicate with the openings. Patent Document 2 discloses a configuration in which two sets of these openings are formed in the upper and lower intermediate portions of the door.

In any structure, the communication path formed inside the door is expanded and contracted to create a muffler effect, attenuate noise and vibration propagating in the communication path, and provide sound insulation with air permeability. It is also designed to obtain sex.

  However, both the structures of Patent Documents 1 and 2 are designed to obtain a noise / vibration reduction effect by utilizing cancellation due to the resonance phenomenon of sound in the passage. ) Has an effect, but at other wavelengths, there is a drawback that the desired sound insulation effect cannot be obtained. In particular, in the structures of Patent Documents 1 and 2, there is a problem in the position of the opening, and exhaust of harmful air mainly formed in the ceiling and middle part of the room is not sufficient, which is inconvenient for ventilation circulation through the door. It was a sufficient structure.

  The present invention solves the above-mentioned problems. The object of the present invention is to obtain an effective sound insulation effect by blocking and absorbing and attenuating the sound itself inside the door, and through the door. It is an object of the present invention to provide a ventilation sound insulation door that can efficiently perform ventilation circulation in both rooms.

In order to achieve the above object, the present invention provides a door 7 in which one and the other surface plates 11A and 11B are attached to the front and back of a door frame 20 formed by upper and lower saddles 8 and 9 and left and right vertical saddles.
The upper ventilation path 14A, the lower ventilation path 14B, and the intermediate shielding part 7a are formed in the upper, lower, and middle parts inside the door frame body 20,
The intermediate shielding part 7a has a sound absorbing or sound insulating structure,
The upper and lower ventilation paths 14A and 14B are formed in the corresponding upper and lower flanges 8 and 9, open on the upper and lower end surfaces thereof, and upper and lower ventilation holes 8a and 9a communicating with the inside of the door 7, and on the upper and lower sides of the intermediate shielding portion 7a. The upper and lower openings 16 and 17 formed in the opposing one and other surface plates 11A and 11B, and the upper and lower ventilation passages 7b and 7c communicating the upper and lower ventilation openings 8a and 9a and the upper and lower openings 16 and 17 inside the door. And formed by
On at least one surface of the opposing inner wall surfaces constituting the upper and lower ventilation path portions 7b and 7c, a sound absorbing material 12 formed of a sound absorbing porous material is provided at intervals to form the upper and lower ventilation paths 14A and 14B. It is characterized by that.

And can be provided opposite to each other.

  The intermediate shielding portion 7 a has a vertical width 5 to 8 with respect to the vertical width 10 of the door frame body 20, and the upper ventilation path 14 A and the lower ventilation path 14 B are vertical to the vertical width 10 of the door frame body 20. The width is 2.5 to 1.

  The intermediate shielding portion 7a is structured such that a sound absorbing or sound insulating material is filled between the upper and lower horizontal rails 10 and 10 provided inside the door frame body 20 at the upper and lower intermediate positions of the door frame body 20.

The upper and lower vents 8a, 9a are formed by slits or a plurality of holes formed in the upper and lower flanges 8, 9.
A.

  The upper and lower openings 16 and 17 are formed by long windows in the width direction formed above and below the intermediate portions of the one and other surface plates 11A and 11B which are the front and back sides, and are permeable shields such as louvers and wire meshes. The upper opening 16 and the lower opening 17 are covered with the materials 16 a and 17 a, and are formed at the front and back positions in a substantially vertical symmetrical position with respect to the intermediate line in the width direction of the door 7.

  The sound insulating material 13 is formed of a viscoelastic sheet material such as rubber or asphalt, and the sound absorbing material 12 is formed of a heat insulating porous material such as felt, glass wool, or sponge, and is spaced from the air passage. And are provided in layers.

  A packing 18 that is in airtight contact with the periphery of the door when the door is closed is interposed in the door contact portion 4a of the door frame 4 that supports the door 7 so that it can be opened and closed.

  In the door where the lower edge of the door 7 faces the floor surface 2, a gap is provided in the lower edge of the door 7 with respect to the floor surface, and a seal tongue piece 19 slidably contacting the floor surface 2 is provided on the lower edge of the door 7. It is protruding.

In the configuration of the door 7, as shown in FIG. 2, when exhausted from the chamber R 1 side to the outside (the chamber R 2), the air in the upper portion of the chamber is from the gap d on the upper end surface of the door 7 and from the upper vent 8 a The air is exhausted along the upper ventilation path 14 </ b> A from the upper opening 16 that forms an exhaust window on the outer surface of the door 7. Further, the air in the middle of the chamber passes through the lower ventilation path portion 7c and the lower ventilation port 9a in the door 7 from the lower opening portion 17 serving as an intake window in the middle lower portion of the door 7, and exhausts from the gap d on the lower end surface of the door 7. Is done. The outer surface of the upper end portion of the door 7 is hermetically shut off by the packing 18 of the door contact portion 4a, and the exhaust is introduced into the upper vent 8a of the upper end surface of the door 7. Further, since the inner portion of the lower end surface of the door 7 is in contact with the floor 2 surface of the seal tongue piece 19, the exhaust is discharged out of the room R <b> 1 from the lower vent 9 a of the lower end surface of the door 7.
Indoor and outdoor noises are sound-insulated by the sound insulation material 13 formed in the intermediate shielding part 7a and the upper and lower ventilation path parts 7b and 7c, and noise entering along the upper and lower ventilation paths 14A and 14B is caused by the sound absorbing material 12. Sound absorption is attenuated.

  According to the present invention, since the ventilation path for circulating the rooms partitioned by the door is formed up and down above and below the door, ventilation between the rooms can be efficiently performed through the door, and in the ventilation path, Since the noise and the vibration and sound are attenuated and absorbed, a sufficient sound insulation effect can be obtained, and a heat insulation effect by a sound absorbing material or the like can be obtained.

  The ventilation path above and below the door forms an upper ventilation path along the ceiling portion and a lower ventilation path along the indoor intermediate layer, and can exhaust indoor harmful air quickly and without leakage.

Further, at least one surface of the opposed inner wall surfaces of the upper and lower ventilation path portions constituting the upper and lower ventilation paths of the door is provided with a sound absorbing material formed of a sound absorbing porous material at an interval for forming the upper and lower ventilation paths. Therefore, sound insulation and sound absorption can be performed regardless of the wavelength level of noise, and the noise insulation effect is improved.
In addition, on the opposing inner wall surface of the upper and lower ventilation path portions constituting the upper and lower ventilation paths, the upper and lower ventilation paths are formed by the sound insulating material formed by the sound insulating sheet material and the sound absorbing material formed by the sound absorbing porous material. By providing them facing each other at an interval, sound insulation and sound absorption can be performed more effectively, and the noise shielding effect is improved.

  According to the present invention, since an intermediate shielding portion having a sound absorption structure or a sound insulation structure that does not have a ventilation path is provided in an intermediate portion of the door, vibration due to a resonance phenomenon of the door itself and propagation of noise can also be prevented.

  According to the present invention, packing is interposed in the door frame contact portion, and the gap between the door and the door frame is airtightly closed when the door is closed. It can be promptly guided to the ventilation path.

  Further, according to the present invention, since the seal tongue piece that contacts the floor surface is projected at the lower edge of the door, even in the door without a step, the gap between the door and the floor surface is airtightly closed, Sound leakage from this location can also be prevented, and the exhaust from the lower ventilation path can be discharged outward.

FIG. 1 is a front view of a ventilation sound insulation door according to the present invention, and FIG. 2 is a longitudinal sectional view taken along line AA of FIG.
In each figure, a partition wall 3 for partitioning the chambers R1 and R2 is formed between the ceiling portion 1 and the floor 2. A part of the partition wall 3 is opened, and the lower end is a floor surface of the floor 2 inside the opening. A door frame 4 made of the same sash frame is arranged, and one end of the door frame 4 is supported on the inside of the door frame 4 through a pair of upper and lower hinges 5 so as to be openable and closable. A door 7 that can be opened and closed by a door knob 6 is attached, and a door position 4a formed on the sash chamber R2 side of the door frame 4 is in a closed position when the door 7 is closed.

The door 7 is made of wood and has a pair of upper and lower sides that further divide the intermediate position of the frame-shaped space formed by the upper and lower ridges 9 and 9 which are not shown in the figure and the vertical ridges on both sides (not shown). A crosspiece 10 is provided, and one and the other surface plates 11A and 11B are attached to the front and back of the door frame 20 formed by the upper and lower eaves 8 and 9 and the horizontal crosspiece 10. The inside of the door 7 is divided into three equal parts in the vertical direction by a horizontal rail 10, and the intermediate part divided into three equal parts is an intermediate shielding part 7a filled with the sound absorbing material 12 as a whole, and the upper part is on the inner surface of one surface plate 11A. The sound absorbing material 12 is adhered, the sound insulating material 13 is adhered to the inner surface of the other surface plate 11B, and the upper air flow path portion 7b is formed therebetween, and the lower portion is the same surface plate 11 The sound absorbing material 12 is adhered to the inner surface of the other, the sound insulating material 13 is adhered to the inner surface of the other surface plate 7, and the lower ventilation path portion 7c is formed between them.
The sound absorbing material 12 may be attached to one surface or both surfaces of the upper and lower ventilation paths 14A and 14B, and the sound insulating material 13 may be omitted.

  Between the upper collar 8 and the upper lower edge of the door frame 4, a gap d on the upper side is formed so as to have an upper side undercut, and the upper collar 8 penetrates in the vertical direction. Thus, the upper vent 8a is formed to allow air to flow from the gap d into the upper vent path 14A. The upper ventilation path 14A communicates with a horizontally elongated upper opening 16 having a required aspect ratio formed at a lower position of the upper ventilation path 7b on one surface plate 7 on the room R2 side. The upper opening 16 is covered with a breathable shielding material 16a such as a louver or a wire mesh.

  Similarly, a gap d having a required dimension which is a lower side undercut is opened between the lower bar 9 and the floor surface FL of the floor 2, and the lower bar 9 passes through the upper and lower sides of the lower bar 9 and extends downward. A ventilation hole 9a is formed to allow air to flow from the gap d into the lower ventilation path 14B. The lower ventilation path 14B is an upper part of the lower ventilation path portion 7c in the other surface plate 11B on the room R1 side. It communicates with a horizontally long lower opening 17 having a required aspect ratio formed at a position. Similar to the upper opening 16, the lower opening 17 is covered with a breathable shielding material 17a such as a louver or a wire mesh, and a detachable filter or the like is attached thereto.

  Further, between the door contact 4a of the door frame 4 and the periphery of the one surface plate 11A on the room R2 side, as shown in an enlarged view in FIG. Airtightness between the upper edge and both sides of the door 7 and the door frame 4 is ensured in the door closed state. Similarly, as shown in FIG. 4 in an enlarged manner, a seal tongue piece 19 made of an elastic body is projected in parallel with the lower edge of the lower rim 9 on the chamber R1 side, so that the door is closed. Between the lower edge of the door 7 and the floor 2, the gap d between the two is hermetically sealed. The seal tongue 19 can be moved up and down in conjunction with the latch mechanism so as to be lowered in a state where the door is latched, and to be hermetically sealed with the floor surface FL.

  The sound absorbing material 12 is made of a heat insulating porous material such as felt, glass wool, or sponge, and is made of a material that absorbs vibration or sound energy and converts it into heat energy. The sound insulating material 13 is made of a viscoelastic sheet material such as rubber or asphalt, and is made of a material that attenuates vibration or sound energy. When the air passes through the upper and lower ventilation paths 14A and 14B, Alternatively, the vibration energy is absorbed and attenuated by the sound absorbing material 12 and the sound insulating material 13, so that the sound insulating property between the rooms R1 and R2 is maintained. Of course, as the thickness of these materials increases, a greater sound insulation effect can be obtained. However, the thickness of the door 7 itself and the securing of the upper and lower ventilation paths 14A and 14B are naturally set in mind.

  Here, room R1 is a private room space such as a living room, bedroom, children's room, toilet, etc., and room R2 is a common space such as a hallway, hallway, LD, staircase, etc. Although the airtightness around the door 7 is maintained in each room R1, the noise generated on the room R1 side passes through the upper and lower ventilation paths 14A and 14B in the door 7, so that these noises are Since the sound is attenuated and absorbed by the paths 14A and 14B, and the space between the door 7 and the door frame 4 and the floor 2 is closed in an airtight state by the packing 18 and the sealing material 19, sound leaks from the chamber R1 to the chamber R2 side. As much as possible, the air permeability is ensured through the door 7. In addition, sound leakage from the room R2 which is also a common space to the room R1 side can be prevented as much as possible, and propagation of sound between each other can be prevented.

  In each figure, the air flow direction is from the room R1 side to the room R2 side. However, when the entire building is maintained in a substantially uniform air-conditioning state, a slight air pressure between the rooms R1 and R2 is used. Of course, there is also a reverse flow depending on the difference or temperature difference. For example, when the room R1 is a toilet and is used, the air inside the room R1 is exhausted to the outside of the building by a ventilating fan or the like. Is the reverse of R2 → R1.

  In the case where the room R1 is another private room space, if the private room heating is performed in the winter season, an upward air flow is generated by the heating in the room R1, so that the flow direction of the air in the upper ventilation path portion 7b changes from R1 to R2. The flow direction of the air in the lower aeration path portion 7c changes from R2 to R1, and thereby, air circulation is performed between the chambers R1 and R2. The flow rate of air is determined according to the gap d and the opening areas of the upper and lower openings 16 and 17 and provided inside the door 7 as long as there is no large pressure difference between the chambers R1 and R2. Due to the heat insulation effect of the sound absorbing material 12 and the sound insulating material 13, the exhaust heat that has risen is exhausted and fresh outside air is taken in, so that it falls within the allowable range.

  On the contrary, when the individual room is cooled in the summer, the cooling air generally descends in the room R1 due to the downdraft, and it is difficult to generate an updraft. Therefore, the flow direction of the air in the upper-side ventilation path portion 7b changes from R2 to R1. In addition, the flow direction of air in the lower-side ventilation path portion 7c changes from R2 to R1, and thereby air circulation is performed between the chambers R1 and R2.

  In the embodiment, the upper and lower openings 16 and 17 are simply covered with the air-permeable shielding member, but a detachable filter may be attached at this position.
