Abstract

FIELD: transport.

SUBSTANCE: invention relates to transport machine building. Soundproof panel contains steel plates fixed from both sides ob flexible material, in particular on metal grid coated with basalt fibre. In the places of long components passing in the soundproof panel, shaped holes are made, e.g. rectangular. In the holes, split plates made of resilient elastic material, e.g. of rubber, are installed. Split plates are fixed by splines to steel plates forming the shaped holes. Slit between steel plates is sealed by attachment splines. Method of soundproof panel manufacturing consists in wrapping the metal grid by basalt fibre fabric. Grids are laid between set of top and bottom plates and fixed by coupling screws. On the soundproof panel, marking for long components location is made. According to marking, top and bottom steel plates are removed together with metal grid and basalt fibre fabric thereby forming shaped holes. Between steel plates, metal grid and basalt fibre fabric slit is made from soundproof panel edge to shaped hole. Then long components are placed through the slit in soundproof panel with shaped hole. The soundproof panel is fixed on grating.

EFFECT: better acoustic insulation and lower rigidity of soundproof panel is achieved.

Description

The invention relates to a device for isolating sound vibrations and can be used in sea, river and land transport, oil pumping stations, the shells of which are covered with soundproof panels from the inside.

The soundproofing panel and the method of its manufacture (Pat. 2340478, IPC B60R 13/08, publ. 10.12.08, Bull. No. 30), made in the form of separate geometric shapes, for example square plates, mounted on both sides on a flexible material, in in particular, on a metal grid coated on both sides with a cloth, for example, of basalt fiber, and the method consists in securing the panel to the crate with fixing screws and to the metal mesh with fixing screws, while the set of lower square plates are offset relative to the upper square Astin, and both sides of the metal mesh are covered with basalt fiber fabric, a mat made of basalt wool, wrapped in basalt fabric, fixed with screws on the crate, is installed on the upper square plates.

A disadvantage of the known analogue is the design complexity, because of which it is impossible to mount a soundproof panel on the inner wall of the vehicle body, on which pipelines, cables and wires of various sections are installed.

The closest in technical essence and the achieved technical result is a soundproofing panel and a method for its manufacture (Pat. 2368518, IPC B60R 13/08, publ. 09/27/09, Bull. No. 27), made in the form of steel plates having larger openings, than long products of various sections passing through the hole, and on both sides of the plates in the center of the hole there are two split discs held by leaf springs fixed to the steel plates, and the manufacturing method is that the split discs made of two halves with the possibility of displacement in the radial direction relative to the steel plates.

A disadvantage of the known prototype is the complexity of manufacturing and the difficulty of fixing such a panel on the inner wall of the housing, when long products, in particular pipelines of different sections, do not pass in heaps in one bundle, but at different distances from each other.

The objective of the invention is to eliminate these drawbacks and to allow passage through the panel of lengthy products spaced at different distances from each other, the technical result of which is to increase sound insulation, reduce stiffness, simplify the manufacture and installation of a soundproof panel.

The technical result is achieved due to the fact that the soundproof panel containing steel plates fixed on both sides on a flexible material, in particular on a metal mesh coated with basalt fiber fabric, differs in that in the places of passage of long products in the soundproof panel there are shaped holes for example, rectangular, in which split plates of elastic elastic material, for example rubber, are mounted, fixed by strips to steel plates forming curly holes TIFA and cut between the steel plates, extending from the opening to the edge of the panel edges sealed mating straps.

A method of manufacturing a soundproofing panel is that the soundproofing panel is marked at the location of long products, the lower and upper steel plates are removed from the marking along with the metal mesh and basalt fiber fabric, forming curly holes, then a cut is made between the steel mesh plates and basalt fiber fabrics, after which, through a cut in a soundproof panel with a figured hole, it is placed on long products and the soundproof panel closes They heat it on the crate, and steel plates in the places of the cut are sealed with docking strips.

On a plate of elastic and elastic material, cross-sections of long products and holes for fastening to steel plates forming a figured hole are also marked, holes in which long products are located, and holes for fastening a plate of elastic material to steel plates, then cuts from the hole to the edges of the plate of elastic elastic material for the entry of long products into the holes of the plate of elastic elastic material, and then tightly mount they are buried on long products, securing with screw bars on steel plates.

The invention is illustrated by drawings:

figure 1 is a General view of the soundproof panel;

figure 2 - section aa, mounting the plate of an elastic elastic material;

figure 3 - section BB, the connection of the steel plates in place of the cut.

The soundproofing panel 1 (Fig. 1) contains upper steel plates 2 and lower steel plates 3, fixed on both sides by clamping screws 4 (Fig. 3) on a metal mesh 5 (Fig. 2), lined with layers of basalt fiber fabric 6, figured an opening 7 for accommodating long products 8, on which a plate 11 of elastic elastic material, such as rubber, having an opening 12 and a cut 13, is fixed to the steel plates 2 and 3 by screws 9 and a strap 10.

On the soundproofing panel 1 between the upper and lower steel plates 2 and 3, a section 14 is made (Fig. 3), sealed by the connecting strips 15. The soundproofing panel 1 is attached to the crate 16.

A method of manufacturing a soundproofing panel is as follows.

Mark the figured hole 7 in the soundproofing panel 1 at the location of the long products 8 and remove the upper and lower steel plates 2 and 3 together with the metal mesh 5 and the basalt fiber fabric 6, forming a figured hole 7, then make between the steel plates 2 and 3 section of the metal mesh 5 and basalt fiber fabric 6 from the edge of the soundproofing panel 1 to the figured hole 7.

Also, on the plate 11 made of elastic material, mark up sections of long products 8 and holes for fixing it to steel plates 2 and 3, forming a figured hole 7. By marking, cut out holes 12 and holes for fixing plate 11 from elastic material to steel plates 2 and 3, then make cuts 13 from the hole 12 to the edges of the plate 11 of elastic elastic material.

Install the soundproofing panel 1 on long products in the following order.

Through section 14, a soundproofing panel 1 with a figured hole 7 is placed on long products 8, after which section 14 is sealed with docking strips 15, and a soundproofing panel 1 is attached to the crate 16.

Then, through the cuts 13, the plate 11 of elastic elastic material is installed through the openings 12 on the lengthy products 8, thereby completely sealing the figured hole 7, and is fixed with screws 9 and the bar 10 to the steel plates 2 and 3 forming the figured hole 7.

The use of the present invention allows to simplify the fastening of the soundproofing panel on the inner wall of the vehicle body and to increase sound insulation.
