Definitions
- the present invention relates to the acoustic insulation of a glazing.
- Insulating glass is commonly used in the building to improve the thermal insulation of premises.
- Glazing generally comprises two sheets of glass associated by means of an intermediate frame which keeps them at a certain distance from one another by trapping between them a layer of air or gas.
- the glass sheets may have a thickness of 4 mm and be separated by an air or gas gap generally between 6 and 24 mm.
- these glazings have limited acoustic performance, notably lower than that of a monolithic glass of the same overall surface mass and, in particular, double glazing having two sheets of 4 mm have poor acoustic performance.
- Various means are used in industry to improve the acoustic performance of these insulating glazing. The most common way is to increase the thickness of the glass sheets, but this technique has limited effectiveness and increases the weight of the glazing.
- Another way is to increase the thickness of the air space, but the effect is only noticeable for air thicknesses of several centimeters, which prevents the production of sealed insulating glazing.
- EP-0 100 701 discloses a glazing whose glass sheets are formed by special laminates incorporating particular polymer films. This type of glazing allows a very clear improvement compared to ordinary insulating glazing, but the cost price is also significantly higher.
- Some publications have proposed glazings formed from monolithic glass sheets of standard thickness, outside of which are installed Helmhoitz resonators tuned to the resonance frequency of the air gap enclosed between the glass sheets with which they are connected. It is recalled that a Helmhoitz resonator is constituted by a cavity which communicates with the outside by a narrow orifice. When an acoustic pressure acts on said orifice, it tends to vibrate the mass of air contained in the cavity at a certain frequency which is a function of the dimensions of this cavity.
- the Helmhoitz resonator is used to attenuate low frequency oscillations; its effectiveness is maximum around its frequency of acoustic resonance as well as its harmonics.
- Patent DE 3,401,996 relates to a variant of the previous system applied to a glazing unit, which uses only one resonator of
- a glazing which is provided at its periphery with a waveguide which communicates with the air gap by several orifices whose shape, section and position are determined so as to detune the acoustic and mechanical waves which arise respectively in the air space and on the glass sheets when the glazing is subjected to an incident sound field.
- This waveguide is embodied by a single profile around the insulating glass, arranged along the sides of the intermediate frame, internally with respect to this frame, with holes preferably in the middle of the sides to ensure communication between the inside the waveguide and the air gap.
- this waveguide is formed of several rectilinear profiles whose ends are not contiguous, thus providing additional communication passages between the interior of the waveguide and the air space.
- the present invention aims to remedy the drawbacks of the prior techniques presented above and relates to an acoustic insulating glazing formed from two monolithic glass plates or others, with improved acoustic efficiency, reserving a significant view, with reduced bulk, easy to manufacture and at a cost hardly higher than that of conventional insulating glazing.
- the invention is based on the observation that a glazing formed from two glass plates and which is subjected to incident acoustic excitation is the seat of several vibro-acoustic modes, but that one of the acoustic modes which carries the most energy from one plate to another is that in ⁇ / 2. So if we essentially attenuate this mode in ⁇ / 2, we eliminate most of the acoustic energy transmitted from one glass to another.
- the invention relates to an acoustic insulating glazing of the type described in patent EP 0 579 542, that is to say formed from two glass plates separated by a peripheral intermediate frame, enclosing a cavity filled with gas, in particular most generally air, and having an internal waveguide, characterized in that this waveguide consists of at least one straight tubular section disposed at the periphery of the cavity, along one side of the glazing, this profile being provided with a transverse partition which closes it in the direction of its length, arranged at a place of this length which is a function of the acoustic mode which it is desired to attenuate.
- each profile is provided with a transverse partition.
- the position of the partition depends on the acoustic mode to be disorganized: it is placed substantially in the middle of the length of the profile to act on the ⁇ / 2 mode or one third to detune the acoustic mode in ⁇ / 3.
- the central partition can be produced by any suitable means. It can come from manufacturing with the profile during the extrusion thereof or be carried out subsequently, in particular by fitting two profiles of lengths slightly less than half the length of one side of the glazing, on a connector-partition, that is to say equipped with a partition or, in particular in the case of thermoformable plastic profiles, by throttling the section and welding, or a partition can be slid and wedged inside the profile smooth.
- the guide will then be formed for example of tubular profiles, smooth on the inside, in which pads of absorbent material are inserted and are positioned at the desired locations, in particular respectively in the middle of the length of each profile.
- the principle of profiles fitted onto a connector which encloses a pad of absorbent material is also an advantageous practical solution.
- the profiles forming the waveguide can be separated and in this case, their interior chambers defined on either side of the partition communicate with the glazing cavity through the open ends of the profiles which are opposite to the partition.
- a frame is produced from a rectilinear hollow profile by folding it and holes are created in the corners of the frame, in its wall which is intended to be turned towards the cavity internal glazing.
- FIG. 1 is a plan view of an acoustic insulating glazing according to a first embodiment of the invention, with a tearing halfway through the glazing;
- Figure 2 is an enlarged sectional view along the line II-II of Figure 1;
- Figure 3 is a sectional view similar to Figure 1 of an acoustic insulating glazing according to a second embodiment of the invention;
- Figure 4 is a sectional view along line IV-IV of Figure 3;
- Figures 5, 6 and 7 show in longitudinal section three embodiments of the central partition in a profile;
- Figure 8 shows a bulkhead connector;
- Figure 9 is a perspective view of a bracket for connecting the sections together;
- FIG. 10 is a perspective view of a waveguide in the form of a rectangular frame produced by means of profiles assembled with the 5 brackets of FIG. 9 and the bulkhead connectors of FIG. 8.
- the glazing 10 which is shown therein comprises, in a manner known per se, two sheets of glass 12, 14 interconnected over their entire periphery by a joint and seal assembly designated intermediate as a whole by the 0 reference 16 which keeps them separated by trapping between them a flat cavity 18 which may contain air and / or a gas.
- This assembly 16 generally comprises a rigid profile 161 forming an intermediate frame glued to the sheets 12, 14.
- the 16 ⁇ profile is provided, on each of its lateral faces in D in contact with the glass sheets, with a bonding and sealing bead 16 2 made of butyl rubber and a peripheral sealing joint I63 which sticks to the internal edges of the two glass sheets 12 and 14.
- a waveguide is produced on the periphery of the latter, inside the assembly 16, 0 which communicates with the cavity 18 via orifices placed in appropriate places.
- the waveguide consists of a plurality of straight tubular profiles 20, 22, 24, 26 which are glued to the two glass sheets and to the interior faces of the assembly 16. 5 These profiles have a rectangular section of the same height that the profiles forming intermediate frame 161, and are open at their ends. They include for example in the middle of their length, a middle partition 28 which defines on either side of it two chambers 30, 31. These sections are not contiguous, so that the chambers 30, 31 communicate with the cavity 18 through their open ends.
- the waveguide can reduce the two wavelengths ⁇ / 2 and ⁇ 2/2, .lambda.i and ⁇ 2 being respectively equal to c / L and c / 1.
- the efficiency of the waveguide can be increased by inserting into the interior chambers 30, 31 an acoustically absorbent material 32.
- a desiccant 34 is advantageously placed in the profiles forming a frame. interlayer 16 ⁇ , holes 36 drilled in these profiles 16. and ending inside the profiles 20, 22, 24, 26 of the waveguide, putting this desiccant 34 in communication with the air in the cavity 18, by 1 intermediate waveguide profiles 20, 22, 24, 26.
- FIGS. 3 and 4 differs from the previous one only in that the rectilinear tubular profiles 20, 22, 24, 26 of the waveguide act simultaneously as profiles of the rigid intermediate frame 16. serving keep the two glass sheets spaced apart.
- the production of the glazing is simpler, and the clear view of said glazing is increased.
- the butyl rubber beads I62 which establish the seal with the glass sheets, are deposited on the lateral edges of the profiles of the waveguide and the desiccant 34, as well as possibly the acoustic absorbent 32 are arranged inside these profiles.
- the lateral sides of the tubular profiles 20, 22, 24, 26 are provided with longitudinal grooves 33 situated between the butyl rubber cords 16 2 and the cavity 18. These grooves are suitable for serving as a reservoir safety for butyl rubber or in general the adhesive sealant which could migrate towards the clear view of the cavity 18 under the effect of gravity, temperature or vibrations.
- the partition can be produced in different ways, for example, it can be constituted by a throttle 38 obtained by crushing two opposite walls of the profile ( Figure 5) or a single wall of the profile ( Figure 6). This is particularly practical when the profiles 20, 22, 24, 26 are made of thermoplastic material; then the profile is crushed and heat sealed.
- the partition may also be constituted by a pad 39 with a high acoustic absorption power (FIG. 7).
- the partition can also be produced using a connector-partition 40 as shown in FIG. 8.
- This connector consists of a section of tubular section 41 of short length, for example approximately 2 to 5 cm, of cross-section slightly lower than that of the sections 20, 22, 24, 26 of the waveguide, but of the same shape, so as to be able to fit into the latter. It is provided in the middle of its length with a partition 28 and on its periphery, for example directly above the partition 28, with a rib 42 in relief relative to its surface and having a height equal to the thickness of the walls of the profiles 20, 22, 24, 26.
- two half-lengths of profiles fitted on this connector will simply constitute a waveguide profile with a smooth outer surface, with a partition 28.
- the sound absorbent can also be placed in this connector 40, on each side of the partition 28.
- the partition connector shown in FIG. 8 has longitudinal grooves 43 intended to receive the ribs 37 which protrude inside the profiles 20 , 22, 24, 26.
- Figure 9 shows in perspective a bracket 50 used to assemble the profiles 20, 22, 24, 26 to facilitate their installation inside the double glazing, and in particular to ensure the continuity and solidarity of the interlayer frame of the double glazing insofar as, as shown in FIGS. 3 and 4, the sections 20, 22, 24, 26 also act as an intermediate frame 16 ⁇ .
- Each bracket 50 comprises a central body 51 and two wings 53, 55 having the same external section as that of the profiles.
- the wings end with end caps 56, 58 of reduced section so as to be able to fit inside the ends of the profiles.
- the brackets have windows 54 in their inner corner which communicate the interior of the waveguide with the cavity 18.
- the manufacture of the acoustic insulating glazing of FIG. 3 is done as follows: one begins by constituting the four sections 20, 22, 24, 26 by means of the wall connectors 40 and portions of tubular sections which are fitted to the latter. In the four sections 20, 22, 24, 26 thus formed, the absorbent 32 and the desiccant 34 are introduced, then the sections are assembled by means of brackets 50 to obtain the frame shown in FIG. 10. The length of the sections will be chosen according to the glazing dimensions that we want to manufacture. Next, cords I62 of butyl rubber are deposited on the lateral faces of the intermediate frame thus formed, then two sheets of glass 12, 14 are bonded to the intermediate frame. Next, a watertight plastic bead I63 is injected into the groove which forms at the periphery of the glazing.
- the waveguide can also be produced on demand, in one piece with the desired dimensions, for example by folding a long tubular profile according to the shape and dimensions of the glazing to be formed and by welding or otherwise assembling the two ends of the frame thus produced.
- the partitions 28 will be produced by one of the methods described above, for example by introducing inside the profiled, before folding, four absorbent pads which are positioned so that, after folding, they are in the middle of the four sides of the guide, or even, in particular when it is thermoplastic profiles, by crushing the profile at places and by heat sealing.
- the sections 20, 22, 24, 26 are formed, for example, using tubes and bulkhead connectors. A bead of butyl rubber is then deposited on the lateral faces of each profile 20, 22, 24 and 26 thus formed.
- thermoforming profiles are then deposited inside a glazing during manufacture and already having its lower glass sheet 12 and its rigid intermediate frame 16., bonded to this sheet 12.
- the profiles 20, 22, 24, 26 being in place, juxtaposed on the different sides of the intermediate frame, the glazing is closed by placing the second glass sheet 14.
- Such glazings according to the invention are particularly effective for air knives 16 to 24 mm high.
