Description

P A T E N T B E S C H R E I B U N DRAWING: NOISE PROTECTION - ROLLO vonche: BAUWESEN s i7 nsf is to determine the sound insulation value of a window *) if necessary to increase by removing the entire window system including the masonry reveal is insulated over the entire surface and tightly.

(6) The term window stands here and in the following for window constructions all kinds of window-door systems fixed and movable glass surfaces in and on Building parts, as well as structures and parts of all kinds, whose sound insulation by the present construction can be increased, in feet Z in the greatest possible distance from the respective glass surface, a thin-walled, flexible, rollable, lead-reinforced insulation material, with a high specific weight, tightly fitting, the window cavity in its clear dimensions overlapping, mounted.

The device is movable, i.e. according to the principles of a roller blind or roller shutters, so that the entire surface insulation is simply manual or mechanical operation can be carried out at short notice at any time and removed again can be 0 TECHNICAL SOLUTION A) Preliminary remarks Depending on the structural The noise protection Fig.

Roller blind mounted on, under or in the penster lintel. 1 "6 That can done both inside and outside 0 However, indoor installation is the most common the external installation, however, is only carried out in exceptional cases. that the need for noise protection devices in front of the windows is considerable is larger, since new building projects require appropriate protection (such as box windows, Insulation panes, double windows, etc.) can be planned from the outset, existing ones Windows offer due to their age and mainly because of their mostly simple Glazing, a poor protection against road noise, considering the increasing traffic density continues to increase, building elements that reduce the sound insulation value of the existing windows should subsequently be increased, e.g. attachment windows, additional window sashes, Double panes, etc. are associated with complex conversions and considerable costs. As a result of their construction, they must, as far as possible, be of the desired size Do without the space between the panes. As a result, their effect is in terms of Cold insulation is mostly undisputed, but for sound insulation, a higher value would be desirable, but not reachable.

The present noise protection roller blind is solely aimed at increasing Sound insulation values designed.

The inclusion of the masonry reveal brings a gap between Glass surface and roll, which is between 250 - 500 mm.

The lead-reinforced, pliable material that covers the entire window cavity Insulated over the whole area, due to its high specific weight it brings the optimal prerequisite for effective noise protection.

Since the problem of tightness through guide rails and sensible Assembly could be solved, the guide rails in turn with sealing and sound-absorbing Materials are lined, the sound-insulating effect of the lead-reinforced The full effect of the material.

The noise protection roller blind can also be installed as a double roller blind. Fig.7 B) Technical solution for assembly and operation The following example shows a) the internal installation on an existing window and b) in the case of a new building project, and c) the operation of the noise protection roller blind explained.

B.l) A roller bearing will move onto the lintel - Fig. B of the pipe mounted The lead-reinforced, thin-walled insulating sheet rolls on this pipe on.

This insulating sheet overlaps the window cavity on each side at 50 - 6o mmo It rolls off on the side facing the masonry. Fig. Lc Luf on each side of the window cavity there are jar rails fixed vertically in where the insulating strip runs off. Fig.11 These guide rails are with lip seals and sound-absorbing materials, so that despite the mobility the insulation membrane achieves the greatest possible tightness.

In the case of less stringent requirements, simpler guiding pro - Fig.17 file usable. - Fig.17 ie lower tightness is achieved by doing the same The guide rail is fastened horizontally to the window sill, Fig.18 in never the insulating strip then it joins the structural situation, then you can move to the horizontal Guide rail can be dispensed with and the insulating sheet Fig. 19 rests on the floor be guided.

The upper exit opening of the noise protection roller blind is designed in such a way that that the passage of sound is restricted to a minimum.

This is done by means of an angle profile, which forms the conclusion Fig.20 of the guide rails at the upper end. Fig.21 Or through a guide tube, which is at the same distance as the thickness of the insulating sheet from the masonry will. Fig.22 The guide tube threatens to run parallel to the movement of the insulating sheet.

All bumps that fall in the upper area of the window are caught by an angle profile. Fig.23 This will make a flat The run-off of the insulating membrane reaches Abb024 and ensures a narrow passage opening.

Also the attachment of a semicircular profile on the lower end board of the roller shutter box is possible.

Sound passages that still exist are replaced by sound-absorbing Insulation materials with which the roller shutter box is suffering from, collected.

Finally, it should be mentioned that they all mounted on masonry Parts, especially the guide rails, are backed with insulating materials. Fig.12c B.2) In the case of a new building project, a hollow space is created in the upper lintel left out, the roller bearings, gears and the Fig. 26 rolled up noise protection roller blind records.

The front side is closed with a cover.

The guide rails are immediately inserted into the masonry within Abb027 embedded in the window reveal and plastered around Fig.28 The upper outlet opening mg is held in this way - primarily by two opposing half-round profiles - that Abb029 a sound passage remains minimal, the horizontal guide rail, which forms the lower end, is also immediately in the masonry of the window Fig. 30 inset bank.

B.3 The noise protection roller blind can be operated with all commercially available Driving devices are made.

z ¢ B. Belt pulls, rod crank drives, steel cable pulls with safety winch and electrical systems0 APPLICATION AREAS The noise protection roller blind allows a very high sound insulation value to be achieved for every existing window, without making any structural changes to the window itself must. -Also when installing on the inner lintel, a structural changes are not spoken of 0 The view of the passageway is not changed or impaired.

The subsequent use of insulating panels, joint seals, additional panels etc. and the dismantling of old discs is not necessary.

In the case of new buildings, the noise protection roller blinds can be installed immediately using the appropriate Recesses in the lintel are to be preceded. Also the installation of the guide rails in the masonry of the window reveal, before applying plaster, paint and wallpaper would be useful.

The noise protection roller blind is left in accordance with the one previously taken Made in the workshop and just attached on the spot.

The costs are well below the insulation disk prices that are currently available are on the market.

The installation of the noise protection roller blinds is given in all rooms should be protected against street noise.

In particular rooms in hotels and hospitals, language and musil; studios, Meeting and conference rooms, theaters and bedrooms in private apartments, etc.

In summary, all types of premises that are temporarily opposed to external noise pollution should be protected.

But also where there is noise nuisance to neighbors from internal sound sources should be avoided, the installation is appropriate.

E.g. restaurants with night operation, bowling alleys, tbrurgs rooms, workshops, in living areas, sports halls, etc.

The noise protection roller blind is easy to attach and operate create a wide sales area.
