Abstract

<P>PROBLEM TO BE SOLVED: To provide a gas permeable environment without leaking noise to the outside by being installed in a factory and a general home. <P>SOLUTION: This sound insulating ventilation window is formed into a sound insulating ventilation window by forming a large number of through-holes 5 formed by boring a part between a plate 2 for constituting one surface and a plate 3 for constituting a surface opposed to this plate by filling a sound absorbing material 4 such as glass wool in a casing 1. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a sound-insulating air-permeable member that is mounted inside or outside a window, door, or wall of a factory or general house.

  Opening windows attached to walls, doors, etc. to ventilate the air in factory buildings or general homes is often done, but noise in the factories and homes leaks to the outside, and noise pollution may occur depending on the location. I had a problem. For this reason, a cooling device, a dust remover, etc. are installed in the room, but there is a problem that sufficient effects cannot be obtained or the cost is high.

  Odors, harmful substances and dust are often generated in factories, and it is necessary to remove foul odors and harmful substances and to ventilate them for dust removal and worker health. In summer, the working environment is adjusted by taking in outside air and ventilating and cooling it because of the high temperature. The simplest and most efficient solution for this is to open windows or doors. However, noise in the factory may leak to the outside and cause environmental pollution. There were also security issues such as leakage of information in the factory or intrusion by outsiders.

  Also, in general households, windows and doors may be opened to remove odors and dust generated from the home, but this may cause outside noise to enter the interior, and privacy may be infringed when viewed from outside. There were problems such as being unfavorable for crime prevention.

  The sound insulating ventilation window of the present invention is filled with a sound absorbing material such as glass wool inside the housing, and the hole diameter is several centimeters including the sound absorbing material between the plate constituting one surface of the housing and the plate constituting the surface opposite thereto. A number of through holes are provided. Although the name of the invention is limited to a window, it is not limited to a window but may mean a general member attached to a part of an outer wall of a building. Since the through-hole connects the indoor and the outdoor, gases such as air and odorous substances in the gas, dust, and dust can pass through the interior and exterior quite freely, and the interior is cleaned. On the other hand, sound waves enter a hole in a sound-insulating window, collide with the sound absorbing material, and are scattered and absorbed, so that they do not easily attenuate.

  By installing the ventilation windows with sound insulation of the present invention on the windows and outer walls of the factory, it is possible to reduce leakage of the noise in the factory to the outside of the factory, and at the same time, ventilation is performed and a comfortable environment is maintained in the factory. The Also, by installing it on the windows and exterior walls of ordinary houses, the environment of air and noise in the house is improved, and at the same time, crime prevention and safety are improved.

  An embodiment of the invention described in claim 1 of the present invention is shown in FIG. This is a figure of a type that will be installed later on the outside of the window of an existing building, so mounting brackets etc. are attached, but the internal structure is basically the same even if it is a type incorporated inside the building It is.

  A sound absorbing material 4 such as glass wool is filled between the plate 2 constituting one surface of the housing 1 and the plate 3 constituting the surface opposite thereto. The material of the housing is not particularly specified such as stainless steel or resin. A large number of through holes 5 are provided so as to penetrate the sound absorbing material 4 between the plate 2 and the plate 3 in a state where the sound absorbing material is filled in the housing 1. As a result, when viewed from one side, the opposite side can be seen through. The cross-sectional shape of the through hole 5 is circular in the figure, but is not limited to a circular shape as long as processing is possible. Although the mounting bracket 6 is attached in FIG. 1, this is for attaching to an existing building and is not necessary when it is installed as a unit in the wall.

  If the distance between the plate 2 and the plate 3 is large, the sound insulation performance is improved, but considering the ease of attachment and the like, it is about 100 mm to 300 mm. Since the portion of the through hole can be seen through the other side, the gas and the odor contained in the gas can pass easily. However, since sound waves are easily reflected and refracted, they are easily absorbed by the sound absorbing material.

Table 1

Installed a sound-insulating ventilation window with a height of 1400 mm, a width of 900 mm, and a thickness of 300 mm on the outside of the existing factory window, and installed microphones at locations facing the interior and exterior of the sound-insulating ventilation window. The noise level was measured.

  The noise level difference was significant at 1 kHz or higher, and a significant sound insulation effect of 27 dB or higher was confirmed at 2 kHz and 4 kHz. In addition, it is useful to conceal the inside of the factory to the outside by installing a ventilation window having sound insulation properties.

  When a general house is equipped with a ventilation window with sound insulation, the factory aims to prevent the noise in the factory from leaking to the outside, but it also aims to prevent the outside sound from entering the interior of the house. . By installing a sound insulation window that actually has sound insulation, considerable silence can be obtained.

  FIG. 2 shows an example of a protective tube attached to the through hole 5 of the ventilation window having sound insulation properties according to claim 2. Since the sound absorbing material 5 is made of glass wool or the like, it can be damaged or scattered. By attaching the protective tube 7 and the protective tube 8 formed with holes 9 on the side surface of the protective tube to the through hole 5 between the plates 2 and 3, the sound absorbing material 5 can be protected without significantly impairing the sound insulation and air permeability. can do. Although only a part of the hole 7 is illustrated, this shape and number are not limited. In addition, although the protective tube 8 is illustrated as not being drilled, it may be drilled.

  The sound-insulating ventilation window of the present invention can be used as a factory or general household window.

  The whole figure which shows the partial cross section of the ventilation window which has sound insulation of this invention.   Overall view of protective tube according to claim 2 of the present invention
