The loggia guard contains a continuous flat screen, the upper edge of which is located at the level of the handrail, and the lower - at or above the top of the window of the lower floor, while the screen is mounted with an inclined outward perpendicular to the plane passing through its upper edge, the lower edge of the screen above loggia and the line of intersection of the ceiling of the loggia with its rear wall. The design allows the loggia ceiling to be completely protected from the direct flow of external noise, and all secondary reflections of sound from the loggia surfaces are minimized. 2 ill. / S

Description

The invention relates to the construction of residential and public buildings,

In the construction of residential and public buildings, a serious problem is the protection of the open and internal premises of buildings from noise, mainly from land transport. The most effective measures to protect open spaces (loggias, balconies, etc.) from noise are the use of shielding enclosures.

Log fences having a vertical continuous screen are known.

However, these constructions do not prevent the reflection of sound penetrating from the outside from the ceiling and walls of the loggia, and thus do not protect the space of the loggias from external noise. In particular, the fence

has a continuous vertical asbestos-cement screen, the lower edge of which is at the level of the lower surface of the slab of the loggia. At the same time, the sound stream going from the outside, as a rule at a certain angle from below, is freely reflected from the entire surface of the loggia ceiling into its internal space. Moreover, repeated reflections of sound from the walls and floor of the loggia create significant noise discomfort for people in the loggia. Noise enters the room located behind the loggia.

The aim of the invention is to reduce noise penetrating from the outside.

The indicated goal is achieved by that. that in the known design of the loggia enclosure containing a continuous flat screen,

the upper edge of which is located at the level of the handrail, and the lower edge is at or above the top of the window of the lower floor, the screen is tilted with the upper edge outward and perpendicular to the plane passing through its upper edge, the lower edge of the screen of the upper loggia and the line of intersection of the loggia ceiling with it back wall.

Comparative analysis with the prototype allows us to conclude that the claimed design of the loggia is characterized by the fact that the screen is tilted with its top edge outward and perpendicular to the plane passing through its upper edge, the lower edge of the screen of the superior loggia and the line of intersection of the loggia ceiling with its rear the wall.

In FIG. 1 shows a general view of the loggia fence; in Fig.2 - the same cross section.

The loggia enclosure comprises a continuous flat screen 1, the upper edge 2 of which is located at the level of the handrail 3 of the enclosure, and the lower edge 4 at or above the top 5 of the window of the lower floor. The screen is tilted by the upper edge 2 outward and perpendicular to the plane a passing through its upper edge 2, the lower edge 4 of the screen of the superior loggia and the line of intersection of the Ceiling 7 of the loggia with its rear wall 8.

In the proposed solution, the protection of the interior space of the loggias and, therefore, the interior of the building from noise penetrating from the outside is achieved by fulfilling the following conditions: firstly, the fence screen is tilted with the top edge outward; depending on the height of the floor and the depth of the loggia, the tilt of the screen will be 30-45 ° to the vertical; it turns out to be approximately perpendicular to the main noise stream and most effectively blocks the space from it

loggias.

Secondly, the screen should have a maximum vertical size, however, the height of its upper edge is limited by the standard height of the fence and corresponds to the level of the handrail, and the lower edge of the screen should not be lower than the top of the window of the underlying loggia so as not to obscure the interior located behind it .

Thirdly, the sound coming from outside should not be reflected from the ceiling of the loggia. This is achieved by the fact that the upper edge of the screen of the loggia, the lower edge of the screen of the overlying loggia and the line of intersection of the rear

Claims (1)

the walls of the loggia with its ceiling are in the same plane. In this case, the ceiling of the loggia is completely closed from the direct stream of external noise, and all secondary reflections of sound from the surfaces of the loggia are minimized. SUMMARY OF THE INVENTION Fencing of loggias located one above the other, containing flat screens, the top edge of each of which is located at the level of the handrail, characterized in that, in order to increase the noise-proof effect, the screen is inclined by the upper edge outward at an angle of 3-45 ° to the vertical with its lower edge located at the top of the window of the lower loggia and perpendicular to the plane passing through its upper edge, the lower edge of the screen of the upper loggia and the line of intersection of the loggia ceiling with its rear wall. figl
