〈考案の目的〉
産業上の利用分野
本考案は換気ガラリ板に係り、詳しくは、屋内
空気が適当に調整された割合で屋外側と換気でき

持たせた換気筒も提案されているようである。BACKGROUND OF THE INVENTION For example, ventilation pipes are provided on walls to ventilate boiler rooms, air conditioning rooms, central control rooms, and the like. A ventilation tube has one end facing outdoors and the other end facing indoors, and promotes air circulation between them, but noise from indoors and outdoors can also enter and exit through this ventilation tube. Recently, ventilation pipes with a noise-reducing function have also been proposed.

でさえ外部に洩れることが多い。 Also, unlike reception rooms, conference rooms, etc., ventilation in apartment complexes and condominiums is performed using entrance doors. For example, Figure 2 shows an apartment,
An example is shown in which ventilation is performed on the hallway side of an apartment, and in this example, a louver board made of punched perforated board 2 is provided at the bottom of the door to perform ventilation. These louvers are effective for ventilation, but when there is a strong wind outside, a considerable amount of outside air can enter the room, and outside noise often enters the room through the louvers, and even conversations inside the room often leak outside.

一体化して成ることを特徴とする。Means for Solving the Problems and Their Effects In other words, the louver board according to the present invention does not consist of a mere punched perforated board, but an outdoor board made of a punched perforated board or a porous sintered board on the outdoor side. At the same time, an indoor board made of a porous sintered board is provided at a distance from the outdoor board to the indoor side, and a channel material or a honeycomb material is interposed between the indoor board and the outdoor board,
It is characterized by being integrated.
以下、図面により詳しく説明する。 A detailed explanation will be given below with reference to the drawings.

FIG. 2 is a front view of a conventional ventilation louver plate in use.
まず、第１図において符号１は多孔質焼結板を

ハニカム材を示す。 First, in FIG. 1, the reference numeral 1 indicates a porous sintered plate, and as described later, in this plate, Al or other alloy powder is sintered without applying pressure, and there are infinitely bent connections between the powder particles. A hole is formed. 2
3 indicates a punched perforated plate, 4 indicates a channel material, and 5 indicates a honeycomb material.

しい。 That is, the porous sintered plate 1 has a thickness of about 2.0 to 3.5 mm, is made of a sintered material of metal and ceramic powder, and the pores formed between these powder particles are connected to form continuous pores, and the porosity is 40%. Energy is lost while sound passes through each communication hole inside and outside, and exhibits sufficient and high sound absorption properties. In addition, in order to make it inexpensive and lightweight, Al or Al alloy powder is sintered into a plate shape in a reducing atmosphere without applying pressure, and in order to impart heat resistance, Al or Al alloy powder is sintered into a plate shape in a reducing atmosphere without applying pressure. Preferably, stainless steel powder is used instead.
また、打抜有孔板２は、第２図に示す如く、従

とができる。 Further, as shown in FIG. 2, the perforated perforated plate 2 is a perforated perforated plate used as a conventional louver plate, and the perforated perforated plate 3 is a so-called punching metal. Any plate can be used.
そこで、第１図ａならびにｂに示す如く、上記
構成の打抜有孔板２又は３から屋外板を構成し、
この屋外板を屋外側に対向させて配置すると共

る。 Therefore, as shown in FIGS. 1a and 1b, an outdoor board is constructed from the punched perforated board 2 or 3 having the above structure,
This outdoor board is placed facing the outdoor side, and an indoor board made of a porous sintered board 1 is placed at a distance from the outdoor board to the indoor side. Further, a metal channel material 4 or a honeycomb material 5 is sandwiched between the porous sintered board 1 of the indoor board and the punched perforated board 2 or 3 of the outdoor board to integrate them. Note that it is also possible to use a porous sintered board as the indoor board instead of using a punched perforated board, and to integrate the indoor board by sandwiching channel material 4 or honeycomb material 5 between the porous sintered board and the porous sintered board. can.
このように構成される構造のガラリ板である
と、曲げ強度の低い多孔質焼結板を用いるのにも
拘らず、内外気の流動をさまたげることなく、曲
げ強度は10倍近く向上する。 With a glazing plate having such a structure, the bending strength is improved by nearly 10 times without interfering with the flow of air inside and outside, even though a porous sintered plate with low bending strength is used.

こともない。 In addition, the ventilation resistance of porous sintered boards is 25 m 3 /min per 1 m 2 of area at a pressure difference of 10 mm water column, so even if outside air enters through the pores of the outdoor board, it will not directly enter the indoors, and ventilation will be slow. It is done properly. Furthermore, since the porous sintered board 1, which is an indoor board, has a sound insulation effect of 4 to 15 dB, internal and external noises are nearly completely muffled. In other words, it is possible to ventilate the room without leaking the conversation outside, and it is possible to adjust the ventilation with appropriate resistance against the expansion and contraction of air due to rises and falls of indoor temperature, and changes in air pressure caused by forced air conditioning using a blower.
Additionally, air can be taken in while suppressing wind blowing in from the outside. Furthermore, since the material is metal or ceramic, it prevents the spread of fire in the event of a fire, and smoke does not directly enter the room unlike with a glazed structure.
〈考案の効果〉
要するに、本考案に係る換気ガラリ板は多孔質

る。<Effect of the invention> In short, the ventilation louver board according to the invention uses a porous sintered board as an indoor board, a porous sintered board or a punched effective board as an outdoor board, and a channel material or a honeycomb material is interposed between them. It has a honeycomb structure.

ム材等の中空部分が介在するため、消音や換気の
調整の効果は一層促進される。 Therefore, since the interior board on the indoor side is made of porous sintered board, for example, even if you install a glazing board on the door or other places to provide ventilation, conversations and sounds inside the room, especially those with high frequencies, will be blocked. The sound is muffled by indoor boards and does not leak outside. In addition, even when air expands and contracts due to temperature changes indoors, or changes in air pressure occur during forced air conditioning, the porous sintered indoor panels provide appropriate resistance. Therefore, ventilation from indoors to outdoors can be appropriately adjusted, and air can be taken in while suppressing wind blowing in from outside. Furthermore, although a porous sintered plate with low bending strength is used, the bending strength is extremely high due to the honeycomb structure as a whole, and because there are hollow parts such as honeycomb material, it is difficult to adjust noise reduction and ventilation. The effect is further promoted.
