Description

This utility model relates to building acoustics and can be used to fix any structures that require vibration isolation, for example, ventilation ducts, ventilation pipes, pipelines of engineering structures, sewer pipes, vibrating engineering equipment and industrial equipment, soundproof frame cladding based on gypsum boards and etc. and other prefabricated structures during construction work in residential, industrial and public buildings.

Known vibration isolation universal mount [RF patent for utility model 95693, publ. July 10, 2010], which consists of a metal bracket, two metal washers, an elastic material (elastic vibration compensator), consisting of two layers, between which a part of the metal bracket, a metal bolt, to which a structure requiring vibration isolation, a metal nut is attached, , which compresses the elastic parts of the fastener, a metal stopper stop, made in the form of a hollow tube, which is worn on a metal bolt between two washers.

This known device is selected as a prototype, since it has the largest number of essential features that match the essential features of the claimed utility model.

However, this prototype has the disadvantage of insufficiently providing vibration isolation, due to the fact that the metal bracket and the metal bolt are perpendicular and, therefore, the vibrations of the structure mounted on the metal bolt are compensated by the same working area (layer) of the elastic vibration compensator, in which it is fixed a metal bracket that can be used both for attaching to a support and for attaching a structure to it. Therefore, the vibrations are damped inefficiently, which reduces the vibration isolation properties of the known fastening.

The objective of this utility model is to create a new vibration isolating mount with the achievement of the following technical result: improving the quality of vibration isolation of a structure by increasing vibration isolation properties.

The problem is solved due to the fact that the vibration isolating fastener includes interconnected elastic vibration compensator, a fastening element for attaching to the support in the form of a metal bracket with a top and a base, and a fastening element for fixing a structure requiring vibration isolation, while the top of the fastening element for the attachments to the support and part of the fastener for attaching the structure to it are located in the elastic vibration compensator in parallel planes, not touching each other.

Possible development options for the main technical solution:

parts of the fasteners are arranged in parallel planes parallel to each other;

parts of the fasteners are arranged in parallel planes mutually perpendicular to each other;

an elastic vibration compensator and two fasteners are interconnected by means of a fastener threaded through them;

an elastic vibration compensator and two fasteners are interconnected using a metal frame, partially wrapping part of the elastic vibration compensator;

as a fastener for fixing on it a structure requiring vibration isolation, a supporting suspension is used, formed from a perforated tape, the ends of which are made with the possibility of fixing structures requiring vibration isolation on them.

Thus, this claimed technical solution, with its whole set of essential features, allows to improve the quality of vibration isolation of the structure due to the improvement of vibration isolation properties, due to the location of the parts of each fastener in the elastic vibration compensator in parallel planes, without touching each other. This makes it possible to increase the degree of damping of the vibrations transmitted through the fasteners, since more than one working zone of the elastic vibration compensator is involved, since parts of fasteners are located in different parts of it, and vibrations are damped relative to different layers, and not of the same as in the known analogue. Consequently, the overall performance of the entire mount grows.

The essence of the claimed utility model and the possibility of its practical implementation is illustrated by the description and drawings below.

In FIG. Figures 1-11 show vibration isolation mounts.

Vibration isolating mount (Fig. 1-11) includes interconnected elastic vibration compensator 1 and two fasteners 2 and 3, parts of which are located in elastic vibration compensator 1.

The elastic vibration compensator 1 and two fasteners 2 and 3 can be interconnected by any known methods and means that compress the elastic vibration compensator 1 so much that both parts of the fasteners 2 and 3 are fixed in it (the vibration isolation characteristics will be determined compression ratio). For example, using metal or another strong material of the frame 4 (Fig. 1-6), partially covering the part of the elastic vibration compensator 1 along the perimeter along with the parts of the fasteners 2 and 3 located in it, thereby fixing the fasteners 2 and 3 in elastic compensator 1 oscillations. In this case, the vibration isolation characteristics are regulated by the compression ratio of the elastic vibration compensator 1 when it is placed in the frame 4, i.e. the excess size of the elastic compensator 1 oscillations in the free state of the size of the frame 4.

It is also possible connection with a fastener 5 (for example, a bolt), threaded through them and fixed with washers 6 and 7 and nut 8 (Fig. 7-11). Moreover, in all elements 1-3, a through hole is made for the passage of the fastener 5. In this case, the vibration isolation characteristics are controlled by the compression ratio of the elastic vibration compensator 1 by adjusting the level of tightening of the nut 8 on the fastener 5, for example, using a stopper (not shown shown) on the body of the fastener 5 or the size and pitch of the thread, or in the additional use of a stopper in the form of a sleeve (not shown in the drawing) (for example, metal, plastic), worn on the part of the fastener 5, located inside the elements 1, 2, 3, between the washer 6 and the washer 7, located on the other side of the elastic vibration compensator 1. The length of the sleeve (not shown in the drawing) depends on the required characteristics of vibration isolation.

An elastic vibration compensator 1 can be formed from one (Fig. 1, 8-9) or more (Fig. 2-7, 10-11) layers of an elastic material (elastomer), for example, rubber, polyurethane, etc., or a self-curing elastomer, for example, silicone resin (in this case, the elastic vibration compensator 1 is formed using the formwork (not shown in the drawing) together with the necessary fasteners 2 and 3).

Moreover, the elastomer layers can be made with either one module of dynamic elasticity, or with different modules, and can have a different shape, for example, cylindrical or rectangular. Moreover, in the case of the formation of a multilayer elastic vibration compensator 1, the layers can be glued or pressed together.

Parts of each fastener 2 and 3 can be located both between different layers of elastomer (Fig. 5), and in different slots made in the elastomer (Figs. 1-4, 6-11). Moreover, in one elastomer can be made two slots (Fig. 1, 8-9) or one slot in one layer of elastomer (Fig. 2-4, 6-7, 10-11). Moreover, the layers of the elastic compensator 1 of the vibrations with a slot can also be supplemented with layers without a slot (Fig. 2, 11).

In addition, the elastomer layer with part of any fastener 2 or 3 can be located in its own frame, which are fastened together using, for example, glue (not shown in the drawing) and / or fastener (not shown) (Fig. 3 , 6).

As a fastening element 2, designed to be attached to the support (not shown in the drawing), a metal bracket is used, the top of which is located in the elastic vibration compensator 1, and at the base of which are made at least two holes 9 for attaching it to the support (not shown in the drawing shown).

As a fastening element 3 for fixing the structure to it, a supporting suspension formed from a perforated tape, the ends of which are made with the possibility of fixing structures requiring vibration isolation on them, can be used. Bearing suspension may be made of metal, wood or polymer, for example, in the form of a flat tape (Fig. 1-11), with the ability to elastically bend and unbend to locate its part in the elastic vibration compensator 1 or volumetric strip (not shown) , part of which passes through an elastic compensator 1 of the oscillations, to which is attached a structure requiring vibration isolation.

The fastening elements 2 and 3 do not touch each other and are located in parallel planes parallel to each other or mutually perpendicular and directed in opposite directions (Fig. 1, 2, 4-6, 9-11) or mutually inverse (Fig. 3, 7 , 8). This is determined by the type of support and the necessary characteristics of vibration isolation of the structure. So, for example, the reciprocal arrangement of fasteners 2 and 3 is preferable when installing heavy structures (not shown in the drawing).

The distance between the parts of the fasteners 2 and 3, fixed in the elastic compensator 1 of the vibrations, is determined by the tasks of vibration isolation of the structure.

As a support, a wall, ceiling, floor, partitions (metal elements of the frame, rack profiles) can be used.

Vibration mount is collected and used as follows.

The top of the fastener 2 and part of the fastener 3 are located in the elastic vibration compensator 1 and are connected together. Then, the fastener 2 is attached to the wall with fasteners, for example, screws (not shown), and a fastener (not shown) is attached to the fastener 3, which requires vibration isolation, for example, with fasteners (not shown )

Thus, the technical result of the claimed utility model is achieved, namely, improving the quality of vibration isolation of the structure.
