A - DESCRIPTION

1- TECHNICAL AREA OF THE INVENTION

  The present invention relates to a set of prefabricated elements.

  qués of construction intended primarily for the individual house

  dual for the protection of its environment. These elements a

  When assembled, they form noise barriers and / or windbreaks.

2- STATE OF THE PRIOR ART

  The construction of noise barriers is reserved until pre-

  smells of works of medium or great importance. They are rea-

  read by specialized companies working on behalf of major clients (Roads, Motorways, Railways ...)

  which have a vocation of public service.

  These companies and project owners each have an obligation

  result, depending on the nuisance observed and the pro-

  regulatory sections to be ensured (Noise Law of 31 Dec. 92).

  This obligation of acoustic result, often associated with an architectural obligation, leads in most cases to studies and to complex and costly realizations, inaccessible

for an individual's budget.

3- STATEMENT OF THE INVENTION

  The purpose of the present invention is to make available to unqualified individuals, elements presented in the form of

  kit allowing them to build noise barriers and

  wind without the aid of lifting means or special tools.

  3.1- On the technical characteristics The screen according to the invention essentially consists of two parts:

  - Acoustic panels with posts at the top.

  The recommended dimensions for the panels are 1.50 m high

  by 2 m wide. They are fixed to the posts anchored in the basement-

  sement. - An opaque base in the lower part to ensure stability vis-à-vis the wind essentially. This base can

take two different forms.

2 2780074

  A classic screen solution o The base is then cons-

  with a masonry low wall associated with a buried reinforced concrete footing. A self-stable screen solution where the base is

  then made up of bins made of light materials, placed on the ground,

  seem to each other and ballasted with various materials. This version does not require a foundation and has, among other things, the advantage of being

  removable and reusable on another site.

  The screen according to the invention is in the form of pre-

  manufactured, all manipulable by one or two people and transported

  tables using a private car. The maximum weight required per element is 80 Kg; but we generally limit ourselves to 50 kg.

  maximum element length is 2.50 m to 3.00 m for

  for example, the maximum width is 1.50 m to 2.00 m for

panels for example.

3.2- On the obligation of result

  Noise perception is largely subjective for each

  that individual. Thus a legally admissible result can

  be judged insufficient by an individual and vice versa.

  The invention provides an improvement in isolation from

  to an existing state, without claiming an obligation of result.

  The magnitude of the acoustic attenuations that can be achieved for typical sites is 25 to 35 decibels A and

more specifically from 28 to 32.

  The user himself appreciates the possible result of the application that he will make of it, more or less effective depending on the

site he has.

  3.3- On the cost of the work The user only pays the supply costs for the kit. He himself takes on the organization of the site and the implementation

artwork.

3.4- Detailed description

  The classic screen solution is characterized by the following aspects: For its base, this version generally uses common construction materials, available to the general public. The base resists shocks, dirt and can be used as

3 2780074

  support for vegetation. From the technical characteristics

  ques of the invention and the example given below, many variants are possible: hollow or solid agglomerates, bricks, stones, panels or any other construction element with a unit weight of less than 80 kg.

  Posts and glazing beads can be profiled from the

  merce (HEA, rectangular tubes, folded sheets, etc ...) rough or hot galvanized or aluminum elements specially

  profiles, insofar as these elements can be transported

  the technical characteristics defined above. These posts and glazing beads receive an exterior paint. The base of the posts is equipped with a fixing plate or, it can

  commit to a reservation. Drilled holes are provided to receive

see the glazing beads.

  The device for anchoring the post to the concrete foundation constitutes a particular aspect of the invention. It is described in

detail in the example below.

  Acoustic panels can be opaque (wood, composite, metal, etc.), or translucent (glass, polycarbonate, PMMA, etc.). The choice of translucent represents the real interest of the screen. It provides sound protection and wind protection while maintaining the view of the landscape and the light for the area

  protected. Acoustic posts and panels are not available

  available to the general public under the dimensions adapted to the screen

  lon the invention. They will therefore be specially shaped

  bind. The self-stable screen solution is original because it does

  use of materials not common today, having to undergo a fa-

  baking or special molding to be used.

  The base is preferably composed, under each post, of two "foot trays" and a "head tray", assembled together.

  The materials used for the tanks must be light,

  resistant and rot-proof. These three criteria are characterized by the following limits:

  Lightness: maximum weight of one element = 80 Kg.

  Mechanical resistance: with respect to the weight and the thrust of ballast materials or of the water contained in the tanks, and with respect to the effects of wind, with in particular the forces to

  the installation of the post in the head tray.

4 2780074

  Rot-proof: materials on an outdoor site in contact with soil, plants, moisture, and which may be exposed

either in frost or in the sun.

  For example, we can cite composite materials based on wood plywood, glass fiber fabrics and resins

  epoxy; polyester reinforced with fibers; reinforced PVC; plastic ar-

  més et injectés; light resin concrete; or all other materials

  suitable with a pleasant surface finish and finish

their.

  The succession of tank beds forms a ma-

  çonnerie to give cohesion to the base. In the transverse direction, the tanks can be assembled strictly superimposed or offset by 20 cm to provide a vegetable surface on the walls of the base. The connections are made using screws, nuts

  and stainless steel washers to resist stress and corrosion.

  These tanks are ballasted with pulverulent or liquid materials (earth, rubble, water, etc.) in sufficient weight to ensure the stability of the entire screen. This ballast can be topsoil. It will be said that the containers are "vegetable". They can be integrated into a pleasure garden. The following three criteria

  allow this function: the upper surface of the bins is wide-

  open to allow the passage of plants and their

  your, the bins admit topsoil as ballast and finally the bottom of the bins is arranged in water reserve as illustrated in

Plate 7.

  The post is anchored in the head tray. It can be done in

  various materials such as for example composite materials

  bin laires; resin concrete, or fiber concrete; profit

  metal strips; wood of sufficient strength (oak, azobe,

  etc ...); o all other suitable materials.

  The acoustic panels are identical to the Classi- solution

than.

  Both classic and self stable solutions are compatible with-

  be them. The position of the acoustic panels is aligned with a

  lution to another. The same screen can therefore be mixed.

4- MODES OF EMBODIMENT

  We present two examples of implementation: a classic screen

  that and a self-stable screen. Their dimensions have been verified.

  trusted for a wind defined by French Rules NV 65, in the region

III, normal site.

4.1- Classic SCREEN

Drawings on plates 1 to 3.

  Plate 1 = Overall plan: The drawings show in order of assembly: The reinforced concrete foundation (1) which ensures the stability of the structure, essentially under the action of the wind. Considering the

  diversity of sites, this part of the work may present

  my very different. For this reason, it is at the initiative of the user.

  - The anchor (2) which ensures the connection between the sole and the

  metal sheet. See details on plate 2.

  - The metal post (3) which holds the panels

  acoustic. This post is anchored either directly in the foundation

  tion, as shown in this example, either in the upper part of the base, if the latter is sufficiently resistant. In this case, the post is shorter and therefore less stressed. It can be chosen from a material with lower mechanical characteristics

  steel (see posts for head trays).

  - The masonry base (4) which contributes by its weight to the stability of the structure. We have chosen to lay here blocks

  store 25 X 50 X 20 cm (H X W X 1), coated on both sides.

  However, we plan to create specific elements-

  adapted to this application and which can then benefit

patent protection.

  - The acoustic panel (5) which provides protection for the upper part of the screen. We have chosen here a PMMA 15 mm thick. A lesser thickness requires a cover of

  reinforcement in the upper part to resist wind.

Plate 2 = Anchoring for pole:

  The anchor (2) provides the connection between the sole and the post.

  The originality of the device lies in the shaping of two gaba-

  rits (6) which give the exact position of the threaded rods (7) to receive the post plate. The lower template, in heavy plate,

  transmits the force of the rods to the concrete and to the reinforcement of the foundation

  tion. The upper gauge, in light sheet metal, has only a role of

  positioning of the rods. This device makes it possible to adapt to all

  the anchor depths using commercially available threaded rods. The distance between the two sheets is determined by the reinforcement of the foundation. The shaping and mounting of these two

  templates allows correct placement of the concrete of the foundation

tion.

  Plate 3 = Post and glazing beads: The post here is a commercial HEA 120 profile, galvanized to

  hot. It is lacquered in the oven with polyester paint. The pa-

  recloses (8) secure the acoustic panels to the posts, the base and the upper cover, if any.

  They are made of steel sheets, galvanized and la-

like posts.

4.2- Self-stable SCREEN

Drawings on plates 4 to 7.

  Plate 4 = Overall plan The drawings show in order of assembly:

  - The self-stable base (10) and (11) which ensures the stability

  lity of the work, mainly under the action of the wind. At the pre-

  alable, the seat floor (9) must be properly leveled and sta-

  bilisé to admit pressures of the order of 5 T / m2. The soubas-

  sement is transversely composed of "foot trays" (10) and

  of a "head tank" (11), assembled together.

  - The post (12) which The material ensures the holding of the panels

acoustic.

  - the ballast material of the tanks (13), which is earth here-

  getal. (See details in Plate 7). The minimum ballast is

  1060 Kg for a head tank and 850 Kg for a foot tank.

  - the acoustic panel (5) identical to the conventional solution.

  Plate 5 = Head tank (11): It is naturally alone at the top of the base. Its essential role is to maintain the post and the acoustic panel. The

  embedding area undergoes significant local efforts and is di-

  measured accordingly. It is characterized by a metallic wall

  diane playing the role of stiffener and distributing the force of the po

  over the entire section of the tank. The post is clamped on the middle wall by two threaded stirrups. This device admits all

  post thicknesses, depending on their nature.

Plate 6 = Foot trays (10):

  There are two per bed to provide natural stability.

  turelle. They are joined or separated according to the choice of the user. The screen can be mounted with one, two or zero beds of

  foot. The tanks (10) and (11) shown here are made of materials

posites.

7 2780074

  Plate 7 = Details: The post (12) shown here is made of composite materials, it is one of the original parts which are the subject of this patent. His

  finished appearance will be similar to the surface of the tubs to form an

  looks homogeneous. The water reserve at the bottom of the tank is intended for vegetable tanks-

  sands. Water is in reserve in the gravel area (14) which

  must be fairly coarse (15/30 mm for example = index of vi-

important).
