Description

Изобретение относится к строительству и предназначено для возведения зданий, к помещениям которых предъявляют повышенные требования по звукоизоляции.The invention relates to the construction and is intended for the construction of buildings, the premises of which have increased requirements for sound insulation.

. Известны оконные блоки с устройствами для естественной вентиляции, содер- 5 жащие канал, облицованный звукопоглощающим материалом [1] .. Window blocks with devices for natural ventilation are known, containing 5 channels lined with sound-absorbing material [1].

Однако данные блоки недостаточно эффективны для защиты помещений от шума, особенно в области низких и средних час- ¹⁰тот, так как звуковая энергия поглощается только звукопоглощающей облицовкой, расположенной на небольшом участке канала.However, the data blocks are not effective enough to protect premises against noise, especially at low and medium chas- ¹⁰ that, since the sound energy is absorbed only by the sound absorbing lining arranged on a small section of the channel.

Указанные недостатки в некоторой ' ¹⁵ степени устранены в конструкциях оконных блоков, в которых естественная вентиляция помещений осуществляется через канал, облицованный звукопоглощающим материалом и выполненный с расширительной камерой, в которой установлены с возможностью вращения навстречу один другому под действием воздушного потока лопастные элементы, облицованные звукопоглощающим материалом Г 2 J .These drawbacks in a ^"15 degree eliminated in constructions window units in which natural ventilation of premises through a channel lined with sound absorbing material and formed with an expansion chamber, in which are rotatably mounted towards one another under the action of the air flow blade members, lined with sound-absorbing material D 2 J.

Однако такие блоки сложны в изготовлении и требуют расхода дорогостоящего звукопоглощающего материала, что ограничивает возможность их использования в условиях массового жилищного строительства.However, such blocks are difficult to manufacture and require the consumption of expensive sound-absorbing material, which limits the possibility of their use in the conditions of mass housing construction.

Наиболее близким по технической; сущности и по достигаемому результату к предлагаемому является оконный блок, содержащий коробку, в которой закреплены установленные параллельно друг другу стекла, и размешенные вдоль боковых сторон коробки вентиляционные камеры, имеющие входные отверстия с жалюзийной решеткой и связанные каналами с промежутком между стеклами, причем стенки камер и каналов покрыты звукопоглощающим материалом [3J .The closest in technical; In essence, and according to the achieved result, the proposed unit is a window unit containing a box in which glasses mounted parallel to each other, and ventilation chambers placed along the sides of the box, having inlet openings with a louvre grille and connected by channels with a gap between the glasses, the walls of the chambers and channels are covered with sound-absorbing material [3J.

Недостатком известного технического решения является сложность в изготовлении и высокая стоимость за счет облицовки камерных глушителей и каналов йоотма3 969877 дорогостоящим звукоизоляционным материалом. Блок сложен в эксплуатации, так как доступ к стеклам 'для их периодической очистки от загрязнения затруднен, а наличие камер и каналов уменьшает площадь светопрозрачного проема окон, что ухудшает освещенность помещения. Кроме того, рассмотренная конструкция блока не обеспечивает достаточную вентиляцию помещения и повышенную звукоизоляцию, ι Цель изобретения - повышение акусти. ческой эффективности глушения шума в области низких и средних частот.A disadvantage of the known technical solution is the difficulty in manufacturing and the high cost due to the lining of chamber silencers and iodm channels3 969877 with expensive soundproofing material. The unit is difficult to operate, since access to the glasses for their periodic cleaning from contamination is difficult, and the presence of cameras and channels reduces the area of the translucent window opening, which affects the illumination of the room. In addition, the considered block design does not provide sufficient ventilation of the room and increased sound insulation, ι The purpose of the invention is to increase the acoustics. the high efficiency of noise suppression in the low and medium frequencies.

. Указанная цель достигается тем, что в оконном блоке с устройством для естест-. венной вентиляции, включающем параллельно расположенные стекла, закрепленные с воздушным промежутком в коробке, и вентиляционный блок, расположенный в подоконной части и сообщающийся с наружным воздухом и внутренним помещением, канал вентиляционного блока в центральной части выполнен из отдельных камер переменных объемов, уменьшающихся к центру блока, а стенки входного И выходного отверстий канала выполнены в виде полусферы и имеют рифленую верхность.. This goal is achieved by the fact that in the window unit with a device for natural. ventilation duct, including parallel-mounted glass, fixed with an air gap in the box, and a ventilation unit located in the window sill and communicating with the outside air and the interior, the channel of the ventilation unit in the central part is made of separate chambers of variable volumes, decreasing towards the center of the unit, and the walls of the inlet and outlet openings of the channel are made in the form of a hemisphere and have a grooved surface.

Полусферы входного и выходного верстий покрыты звукоизоляционным териалом.The hemispheres of the input and output versts are covered with soundproofing material.

При таком выполнении оконного блока значительно повышается его эффективность по снижению шума за счет потерь звуковой энергии на внутреннее трение в слое звукопоглощающего материала и в поворотах канала, облицованных звукопоглащаю. щим материалом. Кроме того, граничные частоты волнового совпадения для спаренного переплета и установленного с относом от него стекла будут различны, что устраняет возможность возникновения резонансных явлений в нормируемом диапазоне частот.With this embodiment of the window unit, its effectiveness in reducing noise is significantly increased due to the loss of sound energy due to internal friction in the layer of sound-absorbing material and in the turns of the channel lined with sound-absorbing material. General material. In addition, the boundary frequencies of the wave coincidence for the paired binding and the glass installed with respect to it will be different, which eliminates the possibility of resonance phenomena in the normalized frequency range.

Канал .5 вентиляционного блока 4 имеет входное отверстие 6, закрытое жалюзи 7 и выходное отверстие 8, посредством кото10 рого вентиляционный блок 4 сообщается с воздушным межстекольным пространством 2. Стенки входного 6 и выходного 8 отверстий имеют рифленую поверхность и выполнены в виде полусферы. Канал 5 облицован звукопоглощающим материалом 9.The window unit with the device for natural ventilation includes parallel-mounted glass 1, fixed with an air gap 2 in the box 3, and a ventilation unit 4 located in the window sill, the channel 5 of which in the central part is made of chambers of variable volume, and the chamber volumes are reduced toward the center of the block . The channel .5 of the ventilation unit 4 has an inlet 6, a closed shutter 7 and an outlet 8, through which the ventilation unit 4 communicates with the air inter-glass space 2. The walls of the inlet 6 and outlet 8 of the openings have a corrugated surface and are made in the form of a hemisphere. Channel 5 is lined with sound-absorbing material 9.

Возможен вариант выполнения вентиляционного блока, при котором полусферическая поверхность выходного отверстия имеет подогрев для создания благоприятного микроклимата в вентилируемом помещении. Звуковые волны, генерируемые внешними источниками шума, попадают во входное отверстие 6 вентиляционного блока 4 через жалюзийную решетку 7 и по каналу 5 проходят вместе с потоком воздуха через выходное отверстие 8 в межстекопьное простраство 2, а затем через форточку 10 во внутренний объем помещения. При этом звуковая энергия на пути распространения ослабляется за счет потерь на внутреннее трение в слое звукопоглощающего материала 9, потерь в поворотах канала 5, а также рассогласованием входных импедансов в отверстиях 8 и 10.A possible embodiment of the ventilation unit, in which the hemispherical surface of the outlet is heated to create a favorable microclimate in a ventilated room. Sound waves generated by external noise sources enter the inlet 6 of the ventilation unit 4 through the louvre grille 7 and pass through the channel 5 along with the air stream through the outlet 8 into the inter-window space 2, and then through the window 10 to the internal volume of the room. In this case, the sound energy along the propagation path is attenuated due to losses due to internal friction in the layer of sound-absorbing material 9, losses in the turns of channel 5, as well as a mismatch of input impedances in holes 8 and 10.
