Abstract

A sound insulating element presents a plate-shaped element made up of corrugated paper or pasteboard sandwiched with or without intermediate layers between flat strips (4). The corrugations and layers are glued together so their openings (5) stand at right angles to the wall or ceiling (6) carrying the insulating element. The openings are 4-5 mm wide and the element body stands 3 cm high. The element body (2) is set in a wooden frame (8) and set with this directly onto or at 2-3 cm spacing on the wall etc. The frame (8) should be higher than the element body (2) height (7) and/or the height is divided up so the top part of the frame rests directly on body (2) and made up of fiber or wool or cotton. The fibers can be impregnated with biocides such as inorganic phosphates, silicates or borates, giving protection against fire and fungoidal attack.

Description

The invention relates to a sound insulation element for sound absorption sorption and soundproofing in rooms, for mounting on Interior walls or ceilings, with the characteristics of The preamble of claim 1.

Soundproofing elements come in very different designs manufactured, depending on the specific purposes for which they are made are used, for example with regard to the frequency response of the Sound absorption or damping.

Very often, thin-walled plastic is used for this elements use that are related to the requirements of the Fire resistance is insufficient or the insulation effect are very limited and easy to electrical charges tend to be used again through special equipment of the Material must be reduced or eliminated.

Such soundproofing elements tend to be very quick and strong Pollution.

In the case of renovations, considerable amounts of very bulky waste fall with special waste properties, which only requires great effort and are therefore expensive to dispose of.

In addition, these soundproofing elements are made of plastic the extremely toxic that arises in the event of a fire  Flue gases and thereby pose a latent hazard potential represents.

The object of the invention is to create a soundproofing element fen, the high sound absorbing and sound absorbing property with good fire resistance when using construction combines biologically harmless material, simply as un hazardous waste is to be disposed of and its fire resistance is better than that of the plastics used for it and at the same time is simple and inexpensive to manufacture.

This task is the beginning of a soundproofing element mentioned type with the characteristics of the characteristic part of claim 1 solved.

The subclaims relate to particularly advantageous features Events of the invention and together with claim 1 at the same time part of the description of the invention.

The use of a soundproofing body made of corrugated cardboard or Corrugated paper already results in relatively little Layer height of preferably 3 cm good sound insulation and Sound absorption over a wide wavelength range.

With the layer height and the width of the openings of the honeycomb Sound insulation behavior in relation to the wavelength favorable to be influenced.

The honeycomb can be equipped with very simple impregnation technology with fire retardant and biocidal substances very low or no toxicity very easy with little effort be made.

With appropriate coloring of the edges of the openings of the Honeycomb decorative effects can vary widely become.  

The building biological properties of the honeycomb are very favorable when using and allow disposal as normal Garbage from conversions or replacement due to pollution.

With this arrangement, a very cheap material stands for the sound insulation body of sound insulation elements.

The soundproofing elements can be close to each other or when cheaper or sufficient in intervals, rows or groups, but also individually, can be arranged and square up be polygonal or round or rounded.

They can be attached with a bracket or directly with the Wall or ceiling screwed or they will be in one Distance from the ceiling or wall arranged between 2 and 30 cm, depending on how the wall is chosen was and what reduction of sound reflections and Interference in which frequency areas are targeted. This in turn requires distance and type of attachment, such as Hang with limp or limb brackets on the ceiling or with supports on the wall.

The physical properties are particularly advantageous ten with decorative design of the soundproofing elements connect, with two-part frame training a zurückge set upper part of the frame at the same time an additional Reducing reflections and influencing Interference.

The attachment of rods or profiles of the bracket directly on the honeycomb of the sound insulation body increases the mechanical Rigidity against sagging, especially with large elements, if they are transverse to the direction of the corrugated sheets and planes Paths of the honeycomb of the soundproof body are attached aligned are.  

For easy assembly and achieving good Sound insulation properties are the sliding of the honeycomb across grooves for the running direction of the corrugated sheets and flat sheets Webs on the inside of opposite Frame parts a very successful solution.

To avoid dust or dust in the insulation fiber layer is the attachment of an easily replaceable Intermediate layer is advantageous, which is also on the outside of the Honeycomb can be attached, especially if it is decorative is designed.

To reduce noise in selected frequency ranges to be particularly reinforced is the attachment of a or several damping masses corresponding mass in arrangements advantageous in which the soundproof body on a support plate, e.g. B. wood fiber lightweight board is attached.

To stiffen and increase the static strength of the Sound insulation body is its attachment, such as gluing a frame, especially made of wood because of the building biology manufactured, beneficial; in addition, this framework then advantageous directly or via brackets and detachable on the Wall or ceiling is attached.

The height of the frame can vary depending on the size of the soundproofing element adapted to be varied.

Sound insulation and -absorption when the space of the frame, immediately then to the soundproofing body with a fiber sound insulation layer made of cotton or wool, mineral wool or others, especially plant fibers, one is filled special increase in sound insulation and sound absorption cause tion properties.  

For the decorative design, but also for improvement the strength of the soundproofing body is the attachment of a especially made of aluminum, the front sides of the Soundproof body enclosing angled frame, which also the covers edges facing the wall or ceiling, from great benefit.

The sound insulation is particularly advantageously attached element with two-part brackets, part of which on Frame and the second part attached to the wall or ceiling is and that with each other by side insertion, by Insert against spring force or connected by screwing become and thus solvable, an exchange without destruction are trained to allow.

In a simpler embodiment, in which the infill honeycomb can be eliminated with a fiber sound insulation layer of the soundproofing body on a plate, in the form of a wood fibreboard applied, conveniently glued, which then supports the brackets or ge directly on the wall or ceiling is screwed. The use of an enclosing is Angle frame in the form of a U-profile for strength and preferred for decorative design.

To improve fire resistance and resistance the equipment is against fungi and animal pests especially the honeycomb of the soundproofing body and the fiber sound insulation layer with building biologically harmless substances, esp with inorganic substances such as phosphates, silicates or borates or fluorides or the like that are most simple be applied by watering before installation, from Advantage.
