SU876904A1 - Noise-suppressing screen for highways - Google Patents

Description

one

The invention relates to the field of construction, namely, structures for protection against traffic noise on the highway x.

Known noise-proof screen, made in the form of a vertical wall of y.bestostotsmentnmh sheets L J «

The disadvantage of such a screen is that it violates the architectural appearance of the streets, usually central, especially in the daytime and evening.

The closest in technical essence and the achieved result to the proposed is a screen including pneumatically stressed elements 2.

The disadvantage of the screen lies in the need for a rigid frame for hanging shells, which makes it difficult to assemble and disassemble, and in a stationary, nonseparable form, it also violates the architectural appearance of the streets.

The purpose of the invention is to simplify assembly and disassembly.

This goal is achieved by the fact that in a noise shield, including pneumatically stressed elements, the latter are made in the form of horizontal pipes and vertical pipes made of an air-tight elastic material, combined in sections, one above the other with the formation of a screen frame, and provided with air-tight jumpers and rigid pockets to accommodate the upper sections when dismantling the screen, the lower pipe being metal and attached to the pavement, and the lower section having clone to the sidewalk.

Figure 1 shows the noise shield, a general view of 5 in figure 2 - section aa in figure 1.

Claims (2)

The noise shield consists of pneumatically stressed elements made in the form of horizontal pipes 1 and vertical pipes 2, combined in section 3, placed 3 one above the other to form a frame 4 of the screen. In the cells between the pipes 1 and the connecting pipes of the tension absorbent fabric 5. The pipes 1 and the connecting pipes 2 are made of an air-tight elastic material and are filled with air. In the lower part of the pipes 2, airtight jumpers 6 are installed. The lower pipe 1 is made of metal and attached to the pavement 7 by any known means near the border 8i. The horizontal height of the screen is attached to the pipes J of a rigid metal sheet 9, which are placed under their own weight the longitudinal pipes 1 of the overlying sections 3 when folding the section by depressing the air pressure in the transverse branch pipes 2. Along the motorway, the screen is made in the form of a set of pneumatically connected between blocks. The space between the lower pipe 1 and the border 8 is used to store the screen in a folded state: from the side of the sidewalk 7 this space can be enclosed by a low metal fence 10 used as an obstacle for pedestrians, preventing them from crossing streets in the wrong place. The upper section 3 is made with the roadway in the direction of the highway, the lower section 3 is inclined towards the sidewalk 7, the other sections 3 are vertical or have a slope towards the highway. In the daytime and evening, the screen is folded and not used, and at night it is deployed. In some sections of the streets, it can also be used during the peak hours on weekdays. In the static state, all pipes and nozzles are filled with compressed air and the fabric 5 between them is unrolled. The dismounting of the screen is performed in a coded sequence. First, the pressure in the upper section 3 is released and the upper pipe 1 is lowered into the pocket 9. Then the pressure is released from the second section 3, which drops down and its pipe 1 is lowered into the corresponding pocket 9. The pipe 1 of the upper section 3 does not fall out of its pocket 9 due to the fact that each pocket 9 has the shape of an arc of a circle centered on the center of the pipe of the overlying section 3. All sections, except the bottom, fold towards the highway, the lower one drops towards the sidewalk when relieving pressure and partially rests on the fence. The invention allows to simplify the installation and disassembly of the noise shield. Claims of an Invention Noise Screen for Motorways, Including Pneumatically Tension Elements, are designed so that, in order to simplify installation and disassembly, the pneumatically stressed elements are made in the form of horizontal pipes and vertical pipes from an airtight elastic material, combined in sections, one above the other with the formation of the screen frame, and provided with air-permeable jumpers and rigid pockets to accommodate the upper sections during disassembly a crane, wherein the lower pipe is formed of metal and is secured to the pavement, and the lower section has a bias towards the pavement.
