Vibropodves is an important element of soundproofing structures. It extends great vibration and significantly reduces the transfer of structural noise to the frame of noise protection structures.
The vibropodves is called a P-shaped profile from a metal, having an insertion of elastic material on its upper crossbar, which often uses rubber, rubber or polyurethane. These soft washers take over the action of an acoustic wave and quench her. This happens due to the fact that the power of sound waves is spent on the compression of the gasket and the rotation of the hinge element, without reaching the plane of the protective design. The thickness of the polymer absorber, the greater the vibration amplitude he will be able to pay off. The fastening of the vibropod vehicle is performed by an anchor to the wall or ceiling, and the response part is attached to the profile using the screws.
High customer demand and big vibropod due to the following advantages of products:
- an obstacle to the penetration of low-frequency noise due to high vibroacoustic properties;
- simplicity of design and installation;
- versatility (most of the products can be used when installing both ceiling and wall structures);
- moisture resistance, anti-corrosion properties and long service life.
In the modern market for building and finishing materials, the vibraproves are presented in a wide range. Products are classified at the place of use, the type of fastening, size and material of the noise absorbing washers.
By the type of fixtures the best is the boxed vibropod. It absorbs the sound waves as much as possible and prevents their penetration on the surface of the plasterboard wall or flow. The disadvantages of this species are the high cost and the need for accurate spur sets before installing the profile.
The size of the vibropodves for GLCs are standard, intended for fixing to the profile, having a width of 6 cm, and economy class, combined with a narrow profile (4.7 cm wide). On the application of the product are divided into wall, ceiling and universal types. According to the material of the manufacture of noise absorbing elements – on products from rubber, rubber and polyurethane.
Vibropodves of all kinds are designed for load up to 30 kg. Adjusting the depth of the frame is carried out due to the presence of several holes located on the side sides of the P-shaped structure.
How to make it yourself
You can use homemade vibrobodves. To independently create such elements, you will need perforated plates and pieces of porous rubber. The number of suspensions is calculated individually and depends on the decoration of the wall or ceiling.
For example, in the room, the area of which is 15 square meters, 45-50 vibropodves will be needed for mounting the ceiling construction.
Suspension manufacturing technology is very simple. On the middle part of the perforated plate, it is necessary to fasten the rectangular elements from rubber, after which the edges of the plates should be hooked.
For greater efficiency, it is recommended to use several rubber layers. This will contribute to a better heating of sound vibration, and increase the sound-proof properties of the drywall design.
After the vibropodves are manufactured, it will be necessary to check their quality. To do this, consolidate the products on a wooden bar, after which it will be necessary to hit them about the floor. Immediately after impact, it is necessary to observe the fluctuations of the plates and determine their ability to quench the vibration. The faster the fluctuations will fade, the higher the vibration insulating properties of the suspensions.

How to choose
When choosing vibropodves, it should be remembered that the most important quality of the products is their strength. The suspension lies with a significant load on the holding of sheets of plasterboard, soundproofing material and a layer of putty. The simplest types of ceiling suspensions are able to withstand up to 12 kg of weight load, and budget versions of wall articles will easily hold 15 kg. Reinforced copies are designed for 30 kg for the wall, and 20 kg for the ceiling.
The sound insulation properties of drywall structures are largely dependent on the ability of the suspension to the wasting of vibrations and the suppression of noise. This indicator depends on the quality, thickness and area of rubber or polyurethane washer. To ensure higher noise absorption, it is necessary to choose products with a larger area, thickness and elasticity of material.
FEATURES OF MONTAGE
Installing the plasterboard design on the ceiling consists of several stages.
- Measurement ceiling plane. It is carried out using the construction level and is to determine the lowest angle, from which the distance required for the placement of the lamp and sound insulation material is measured.
- Installation of guide profiles for frame. Pre-for metal structures that will lay down to overlapping, sealing tape passes. This eliminates the appearance of noise bridges, which, in turn, has a beneficial effect on the sound insulation properties of the design.
- Application markup To designate installation places of racks with jumpers. Also marked the location of the vibropodves.
- Fastening vibropodves With the help of a dowel with further lowering their edges.
- Installation of carrier rails Frame and their fixing with vibropodves.
- Laying of sound insulation material on frame and plasterboard.
Installation and operation of the vibropodway is no different from the use of conventional direct attachment. The main task is the right choice of fastening material, which depends entirely on the type of ceiling. You need to connect vibraproves with a frame profile using a press washer or self-tapping screws.
When installing sound insulation design, it should be understood that the complete sound insulation effect will not be able to succeed. However, the use of sound-absorbing devices allows much to lower the level of extraneous noise and makes it in the room more comfortable.
