Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a soundproof wall with radio wave reflecting performance.

(Conventional technology) Conventional soundproof walls are used in the field of architecture to prevent noise from air conditioning equipment in buildings and piping systems related to compressors.
It is arranged to surround the building.

Additionally, in the civil engineering field, soundproof walls are installed along the side edges of elevated automobile roads and elevated railways to prevent traffic noise.

(Problem to be solved by the invention) However, when TV radio waves hit a building surrounded by soundproof walls for noise prevention, TV radio wave damage occurs.

Furthermore, as in the case of elevated automobile roads and elevated railways, soundproof walls intended to prevent noise pollution may become a source of TV wave reflection damage such as ghosting.

As described above, as an environmental problem, the current situation is that the noise problem not only causes environmental pollution by itself, but also becomes a problem in combination with other environmental pollution.

The present invention was proposed in view of the problems of the prior art, and its purpose is to provide a wall that simultaneously reduces noise and radio wave reflection damage.

(Means for Solving the Problems) In order to achieve the above object, the soundproof wall according to the present invention has a sound-transmitting inclined radio wave reflecting plate on one side of the wall mounted with sound-absorbing material. It is configured as follows.

(Function) As described above, the wall body according to the present invention is equipped with sound absorbing material, so it has a soundproofing function, and the wall body has an inclined radio wave reflecting plate with sound transparency arranged on one side of the wall body. Due to this, TV radio waves are reflected into the air in an unaffected direction.

(Example) The present invention will be described below with reference to the illustrated embodiments.

Figure 1 shows an example in which TV radio waves and noise come from the same direction.
The side surface of the wall A in which the sound-absorbing material 2 made of wood wool board or the like is loaded is made of metal, conductive plastic, etc. that easily reflects the TV waves and has conductivity and does not block the sound. The configured radio wave reflecting plate B is arranged at a required inclination angle.

Since the illustrated embodiment is configured as described above, the television radio waves are reflected by the radio wave reflecting plate B into the air in a direction with less influence, thereby reducing radio wave damage.

Noise passes through the radio wave reflecting plate B and is absorbed and insulated by the wall A located on the back side thereof.

As shown in FIG. 4, the television radio waves may be reflected between the radio wave reflecting plates B and reflected into the air in a direction with less influence, thereby reducing radio wave damage.

Note that the radio wave reflecting plate B is a radio wave reflecting mesh 4.
The lower edge of the light metal frame 3 and the wall A
It is constructed by incorporating sound absorbing material into a triangular cylindrical framework formed by connecting the two with a horizontal frame 5, resulting in a unitized structure.

Furthermore, by wrapping the sound absorbing material with a sealing material such as a polyethylene sheet or a polyethylene film, water intrusion is prevented, and the sound absorbing effect and weather resistance are improved.

Fig. 5 shows an embodiment in which the present invention is applied when TV radio waves and noise arrive from opposite sides.The same materials as those in the previous embodiment are used, and in the figure, the same parts as in the previous embodiment are The same reference numerals are given.

Figures 6 and 7 show an embodiment in which the present invention is applied to a soundproof wall W with a radio wave reflector for a motorway, in which a metal radio wave reflecting mesh 4 is successively stretched from the TV radio wave arrival side. A wall body A is provided in which a radio wave reflecting plate B and a metal frame 1 made of a galvanized iron plate are filled with a sound absorbing material 2 made of glass wool covered with a polyfluorinated vinyl film 5.

This soundproof wall W with a radio wave reflector is formed into a unit and is constructed so that it can be connected vertically and horizontally.

(Effects of the invention) The soundproof wall according to the invention provides a soundproofing function and a radio wave reflecting function by arranging a sound-transmitting inclined radio wave reflecting plate on one side of the wall mounted with sound-absorbing material. However, it is possible to reduce noise and radio wave reflection interference at the same time.
