Abstract

FIELD: construction.

SUBSTANCE: method comprises a plant of a heat insulation panel with at least one ventilation hole. The screen is made in the form of a sheet of cellular polycarbonate with dimensions according to the shape of the window opening, where the screen itself is installed and fixed into the external window opening so that air freely arrives into the cross cells ("honeycomb") of the window. The hole is made at the inner side in the polycarbonate sheet.

Description

The invention relates to the field of construction, namely, ventilation soundproof devices in the enclosing structures of buildings and structures.

Known protective device of the window opening (RU 10415 U, ЕВВ 9/02), containing a frame for installation on the wall of the house and at least one rotary shutter, consisting of a frame and horizontal strips mounted in oblique slots of the vertical shelves of the frame, characterized in that the strips are a bent profile (corner) with shanks designed to be placed in the slots of the vertical shelves of the frame and bend inside them, while all the shelves of the shutter frame are rigidly interconnected, for example, by welding, and the strips are mounted in the regiment ah bulges out. Also known is a protective device for a window opening (RU 33389 U, ЕВВ 9/02), comprising a frame for mounting on a wall of a house and at least one rotary shutter, consisting of articulated sections, each of which consists of a stamped metal sheet with horizontal bulges and vertical corrugations at the edges and a corrugated profile welded to the edges of the sheet, characterized in that the frame is made of a profile pipe connected at the corners by welding, and the shutters are placed inside the frame opening.

The disadvantage of the above solutions is their poor sound insulation, almost complete light insulation of the room when using them. Their main purpose is to protect against unauthorized persons from entering the room through a window.

A ventilation soundproofing device is known, comprising a heat-insulating panel with at least one ventilation hole, a double-circuit seal for glazing and a locking mechanism with a valve for closing the openings in the said panel (see EP 0021164 A, 01/07/1981, cl. ЕВВ 7/02). A disadvantage of the known device is that the presence of brush seals does not exclude the possibility of passing through them cold and condensation of water vapor on the inner surface of the insulating panel. In addition, the disadvantage of the solution is the need to install this device inside the window frame, the complexity of the subsequent dismantling, low ventilation flow due to the small size of the device.

The closest solution is a ventilation soundproofing device (RU 2189426, ЕВВ 7/02, published September 20, 2002) containing a heat-insulating panel with at least one ventilation hole and a locking mechanism with at least one valve to close the holes in the specified panel, characterized in that it is equipped with a box mounted on the panel with at least one ventilation hole, and the valve of the locking mechanism is made with a layer of heat-insulating material and placed in the box.

The disadvantage of this solution is the need to install this device in the opening of the window frame, the complexity of the subsequent dismantling, low ventilation flow due to the small size of the device.

The objective of the invention is to provide a removable ventilation soundproofing device that can be used to insert into the window opening from the outside.

The technical result of the claimed invention is a method that allows to ensure the removability of the ventilation noise insulation device, the ease of its installation on the window frame, a more powerful ventilation flow without pronounced cold air, additional functionality in the form of mosquito net properties.

The specified technical result is achieved due to the fact that the method of installing a removable ventilation soundproof screen, characterized by installing a heat-insulating panel with at least one ventilation hole, is characterized in that the screen is made in the form of a sheet of cellular polycarbonate with dimensions in the shape of a window opening, where the screen is installed and fastened into the outer opening of the window so that air freely flows into the transverse cells (“honeycombs”), and the hole is made from the inside in the polycarbonate sheet. The hole in the polycarbonate sheet is made in the middle of the sheet in the form of a vertical slit. A transparent polycarbonate sheet is used. The polycarbonate sheet is coated with transparent soundproofing varnish.

The invention is illustrated by drawings.

Figure 1 shows a window from the outside of the building, a - view with the screen removed, b - view with the screen installed on the window.

Figure 2 shows a window from the inside, and a view with a closed window, b is a view with an open window and a functioning screen in operating mode.

Figure 3 shows a window from the end in section, a - view with the screen installed, b - view with the screen removed.

Figure 4 shows the principle of operation of the screen.

The invention can be implemented as follows.

The ventilation noise shield (4) is formed from a sheet of cellular polycarbonate, which is made in the form of a window opening (2). Then the screen is fastened (see Figure 1, Figure 2, Figure 3), for example, using latches (3) that hold the screen by the edges, into the outer opening of the window (2) so that in the transverse cells ("cells" ) (8) (see Figure 4) air flows freely. To do this, it is enough to fix the screen (4), leaning its plane against the surface of the window frame (1) from the inside. Cells (8) of the screen (4) must remain open.

At least one hole (5) is made on the inside of the screen (4) in the polycarbonate sheet, which is preferably made in the middle of the sheet in the form of a vertical slit going through the maximum possible number of cells (8).

The principle of the screen is as follows.

When atmospheric air (9) enters the room through the lower honeycombs (8) of a polycarbonate sheet (4) by natural draft, it passes through the honeycomb and further into the slot (5) from the inside of the sheet. Warm air (10) leaves the room through the slot (5) and the upper cells (8) of the sheet.

Noise isolation is ensured by the properties of a polycarbonate sheet having a honeycomb structure from partitions between two parallel flat sheets, which provides multiple refraction, reflection of sound waves and, as a result, reduction of sound pressure.

The screen acquires the properties of a mosquito net due to the peculiarities of polycarbonate honeycombs (8), inside which insects cannot fly because of their small size, if additional protection against insects is necessary, a mosquito net is used in the form of additional inserts at the entrance of air flows from the street.

So that the screen does not reduce the properties of the window as a source of light transmission into the room, it is preferable to use a transparent sheet of polycarbonate.

Polycarbonate honeycombs (8) also serve as a heat exchanger, that is, the cold air of the street, passing through the channels, receives heat from the room, which causes it to heat. It already enters the room with a temperature higher than outdoors, which as such eliminates the so-called draft of cold air.

And when coating on both sides of a polycarbonate sheet with a transparent soundproofing varnish (a viscous, drying base), the noise absorption increases accordingly.
