Definitions
- the invention relates to a wall element of a noise barrier, which consist of several arranged next to and / or one above the other, is built up between wall elements, and such a noise barrier.
- a wall element is one mentioned noise barrier created with which the above mentioned requirements are met.
- a wall element at the beginning mentioned noise barrier with two opposite at a distance mutually arranged, parallel wall panels and two Profile strips over which the two wall panels each along two opposite plate edges are interconnected, on which elastic springs are formed, each in one of the profile bar formed, undercut longitudinal groove are engaged.
- the wall element according to the invention thus has a lightweight, hollow box shape. Furthermore, the Wall plates and profile strips are simple components, which easy to mass produce and therefore inexpensive to manufacture are. The assembly of the individual components is also simple and therefore inexpensive because the components are each over a snap connection are connected so that they can be put together quickly and easily. The gap between the two wall plates prevents Sound or other vibration of one plate can transfer directly to the other disk.
- the springs on the opposite plate edges of the respective wall plate, for example on the end faces can be formed, the springs are preferably laterally arranged the wall panels. This is regarding the Assembling the wall element is advantageous because the wall panels with their springs simply from the side into the longitudinal grooves the profile strips can be snapped into place. The wall panels can with their springs, however, along the profile strips in the Longitudinal grooves are inserted.
- the springs can be manufactured separately and on the Wall plate to be attached.
- the respective spring at least one resilient Section on which in the undercut assigned to it Can snap into the longitudinal groove.
- the springs on the are preferred each plate edge integrally formed and as of Plate edge angled to the side, angular, i.e. tab-shaped, leg springs, one of which Leg is resilient.
- the wall panels for example, made of plastic or wood can be made, they are preferably made of stainless steel Sheet. Such wall panels are very weatherproof and can by pressing, roll forming, profiling can be produced inexpensively. Furthermore, the springs, especially the leg springs, in a simple manner Bending the sheet material at the edge of the respective wall plate be formed.
- the sheets are preferably thin-walled and through bevels, e.g. Ribs, stiffened.
- the profile strips are preferably made of plastic. This has the advantage that vibrations of a wall plate are damped to the transmitted to others, reducing the noise level of the Wall element is improved.
- the Profiled strips made of metal, especially light metal, and between the springs and the boundary wall of the longitudinal grooves Plastic strips to reduce vibration transmission be arranged.
- the profile strips are advantageous through Extruded or extruded.
- a sound-absorbing material can be introduced, which the gap e.g. completely filled out.
- a sound absorbing Material provided a soundproofing plate, which between the two wall plates parallel to these and at a distance of is arranged and on the edge of the two Profile strips is attached, one of the two wall panels with a perforation, i.e. with through holes is.
- the distance between the soundproofing panel and the respective wall plate prevents direct transmission of Vibrations from one wall panel over the soundproof panel to the other wall plate.
- the perforation becomes the source of noise arranged facing so that sound waves through the perforated Hit the wall plate directly onto the soundproofing plate and can be absorbed by this. This turns reflections diminished, and the formation of noise-increasing standing Waves are restricted.
- the Profile strips on their inside a U-profile so that the U-profile rail is formed in which is the edge of the soundproofing panel.
- the soundproofing panel between the U-rails is form-fitting held without additional fastenings are necessary.
- the soundproofing panel can, for example simply inserted between the U-rails in the wall element become.
- both Wall plates with through holes, of both Profiled strips on the outside of a side Boundary wall of their U-profile rail a longitudinal slot is formed in which the soundproofing plate covering separating plate, preferably made of sheet metal, on the edge is inserted.
- the soundproofing plate covering separating plate preferably made of sheet metal
- the partition plate can soil, fertilizer with water-storing gel or other base material for plants can be arranged, which are planted in it through the through holes in the assigned wall plate can grow outwards.
- the partition plate can be easily inserted into the Profiled slots can be fitted and reflects sound waves passing through the sound insulation panel back into this for further absorption.
- the partition plate can also with horizontal bars, e.g. Sheet metal, be provided to e.g. Plant containers filled with plant base material are made of jute.
- the profile strips are free Plate edges of the wall plates the associated side Cover plate covering the end face of the wall element attached, which is preferably made of plastic and that Braces wall element.
- the wall element Buffer parts made of plastic on the outside along the Profile bar-free, preferably perpendicular to the profile bars extending edges of the wall element are attached to this.
- the buffer parts are used for e.g. one in a U-profile post inserted wall element damage one To prevent corrosion protection layer of the post and a Vibration transmission between the wall element and the post to reduce.
- the buffer parts are preferred Elongated rubber parts, which run along the entire length the associated edge of the wall element as sealing parts run.
- the buffer parts can be attached to the wall panels his; however, they are preferably on the face of the Cover plates attached.
- the two profile strips on the outside are preferred a key or a longitudinal groove is formed. Alternatively, from the two profile strips on the outside of each Longitudinal groove formed. So in both embodiments adjacent wall elements in the longitudinal groove / s form-fitting key can be connected to each other.
- the profile strips on their Outside advantageous in the longitudinal direction Profile strips extending flange formed.
- the respective Flange is opposed to the side by two angled, running in the longitudinal direction of the profile strips Last formed.
- Wall elements are the strips that form the flange adjacent profile strips with their flat sides on top of each other, so that a larger between adjacent wall elements 1 Pad is created.
- a noise barrier created which with good noise protection properties is inexpensive and easy to install.
- the light and therefore easy to handle wall elements can be in between the U-profile sections of the H-profile posts be used.
- the buffer parts on the respective Wall element allow this to be at an angle to the Legs of the H-profile extends so that the posts do not must be exactly aligned and that also one slight curvature of the noise barrier is possible.
- a wall element 1 has a noise barrier
