Attachment device with acoustic isolation for use in building constructions

Description

Field of the invention

[0001] The present invention is related to the field of construction, in particular to the acoustic isolation of the connection between members of a double-leaf structure, said members being a supporting structure and a wall or panel facing said structure (e.g. an exterior wall, interior wall or ceiling panel), and to an attachment device for realising such a connection.

State of the art

[0002] The problem of acoustics in buildings, caused by the transmission of vibrations in structures are well known in the field of construction. In particular, an internal or external wall or panel located in front of, i.e. facing a supporting structure, must be attached, for reasons of stability, to the supporting structure by attachment devices. These devices are however liable to transmit vibrations from the facing wall or panel to the structure, and thereby transmit noise to the rest of the building. A known solution to this problem is the use of special devices comprising a less rigid damping material, which is arranged to prohibit the transmission of vibration, whilst the device maintains its function of taking up tensile and compressive forces, to thereby ensure the stability of the wall.

[0003] A first known device is shown in figure 1. It concerns an attachment device divided in two parts 2 and 3, wherein the continuity is ensured by a damping material 1, in which the outer ends of the two parts are embedded. Functionally, this device is quite effective, but it is difficult and expensive to realise the connection between the two parts and the damping material during production of the device.

[0004] One way of obviating the abovenamed problem is to realise the device by an assembling technique. Figure 2 shows an example. The damping material is divided in two parts 1a and 1b, which are mechanically attached to a support bracket 4, by the hook 5, which is equipped with assembling means 6. Even though this device is less complex, installation of this device is time consuming and difficult.

[0005] A further known device is disclosed in EP1 548 201 A2.

Aims of the invention

[0006] The present invention aims to provide an attachment device which is simple, while offering the required characteristics in terms of mechanical and acoustical performance, without necessitating a complex installation, and without representing an important production cost.

Summary of the invention

[0007] The invention is related to devices as described in the appended claims. Various embodiments are described in the dependent claims. The characteristic elements of the invention are the following : it concerns an attachment device equipped with an acoustic isolation, arranged to interconnect the members of a double leaf structure in a building, said members being a supporting structure and a wall or panel facing said supporting structure, the attachment device being composed of several elements which are assembled by fitting the elements together, and without using further mechanical connection means. The invention is not limited by any form or shape of the constituting elements of the attachment device.

[0008] In particular, the device comprises three elements, the first being attachable to the supporting structure, the second being a damping element, and the third being attachable to the facing wall or panel. The damping element is formed of a resilient material, and is arranged to connect the other two elements without said two elements making direct contact, so that an acoustic and vibrational decoupling is obtained. In each embodiment, the first element is shaped so as to form an area for receiving the second element by inserting the second element into said area, without necessitating further mechanical attachment means. Likewise, the damping element comprises a receiving area (preferably a hole), for receiving the third element without the help of further mechanical attachment means.

Detailed description of the invention

[0010] The attachment device of the invention is realised by three different elements, the first one being a support bracket which is to be fixed to the supporting structure, the second one being an element formed of a damping material, and the third one being preferably a hook or flat profile, to be fixed to the facing wall or panel. The basic characteristic of the invention lies in the fact of being able to realise the assembled device with the help of constituting elements, especially designed to be assembled without difficulty, by simply fitting elements together. This characteristic allows a considerable cost reduction.

[0011] Figure 3 shows the constituting elements of a device according to the invention. The first element (bracket 10) is provided with an opening 11, so that the damping element 12 may be fitted into said opening (from the left as seen on the drawing). The bracket 10 is arranged to be fixed to the supporting structure and automatically blocks the damping element. Bracket 10 is preferably produced as a plate-shaped element, which is bent at an essentially right angle, to obtain a flat sub-part 13 and an upright sub-part 14. A hole 15 may be provided in the upright sub-part, for attaching the element to the supporting structure. The central opening 11 comprises a first portion 16 situated in the flat subpart 13 and a second portion 17 in the up-right sub-part 14. The width of portion 16 is smaller than the width of portion 17. The damping element 12 is provided as a cylindrical element with a central section 18 having a reduced diameter. The difference in width between the opening portions 16 and 17 in bracket 10 is such that the damping element may be inserted through the up-right opening portion 17, so that the section 18 with reduced diameter fits over the sides of the flat opening portion 16, and is thereby secured. No other mechanical connection is required between the bracket 10 and the damping element 12. The damping element 12 is provided with a central hole 19, which is arranged to receive an outer end 21 of the hook element 20 without a direct contact occurring between the hook 20 and the bracket 10. The second outer end 22 of the hook 20 is fixed to, e.g. embedded in, the facing wall (not shown). Alternatively, as illustrated in Figure 4, the third element of the attachment device may be a flat profile 37, provided with a pin 38, which can be fitted into the hole 19 of the damping element 12.
