Definitions

  • the invention relates to an acoustic screen module comprising a first perforated plate, that can be used to form a side exposed to a noise source, and a second plate that can be used to form a side protected from said noise.
  • These plates define two main surfaces, corrugated or smooth, and comprise on two opposite ends means for coupling to each other.
  • the two plates define an inner cavity that can be used to place a noise absorbing material.
  • This acoustic screen module presents constructive features meant to reduce manufacturing costs for the plates that form the module; allow compact stacking thereof, reducing the space and costs related to storage and transport; facilitate assembly in a quick, simple, safe manner without the need for external attachment elements; and providing for the coupling means of the plates an arrangement and configuration allowing to define assembly stops and break the acoustic bridge at the areas of contact with other modules or with any lower support bases.
  • Noise screens are also known as acoustic shields or barriers. Their function is to prevent the transmission of noise from one side to the other of their physical location. These screens are installed next to communication routes with high noise levels, such as roads, railroads, or airports, and are an effective measure for reducing or eliminating the noise from said emitting source in the area to protect, efficiently reducing the harmful effects and inconveniences resulting from the noise.
  • the screen behaves as an enclosure that defines an obstacle for transmission of the noise between the source and the area to protect, which is an inhabited area.
  • the screen acts as an acoustic insulation against fixed noise sources or traffic by absorbing sound waves.
  • the screens are formed from modules joined to one another to configure a screen with the desired height to fulfil its function.
  • Screens are known that are formed from modules where each module consists of two metal plates or sheets of galvanized steel or aluminium representing the two faces of the acoustic panel.
  • the sheet meant to be on the side to be protected is smooth, without orifices.
  • the configuration of the two sheets is often wavy or corrugated.
  • the sheets or plates have a configuration allowing them to be joined to one another, leaving a space in the middle in which a core of synthetic material, generally rockwool, is placed, as a block placed in the central part of the module that does not cover the spaces defined by the corrugation.
  • the perforated sheet is placed facing the noise source so that the acoustic waves penetrate the screen modules through the orifices of the plate. This is aided by the grooves, waves or corrugation of the plate surface.
  • the synthetic material on the inside, rockwool absorbs the acoustic waves, which are prevented from exiting out of the walls of the module by the smooth, non-perforated plate placed on the side of the area to protect from the noise.
  • the metal screens are made of galvanised steel or aluminium and can have various plate thicknesses and rockwool densities to adapt to the absorption and insulation levels.
  • Each module has closing side covers made of polypropylene that prevent a direct contact between the plates and the support profile.
  • the screen is placed on a support base built as a separation between the modules and the ground on which the acoustic screen rests.
  • the two plates are joined at the factory or workshop or at the work site by elements for attaching the plates, screws or rivets, and using tools.
  • This method of attachment means that the bending stress due to wind pressure causes plasticising in the steel/aluminium and consequently deformations in the plates of the areas of union made by said rivets or screws.
  • Italian patent 2008000049 discloses a module meant for factory assembly of the two plates that it comprises, for which it is not possible to optimise the space in the transport means if the two plates are carried disassembled for installation on-site, since their specific shape does not allow a correct stacking with a uniform pressure exerted on the surface of one plate against the other; instead, pressure is exerted only on some contact points, such that the weight of the stack will deform the plates arranged on the bottom at these areas.
  • the subject matter of the invention is an acoustic screen module of the type discussed above, comprising a first plate, preferably perforated, that can be used to form a side exposed to a noise source, and a second plate that can be used to form a side protected from said noise; these plates define two main surfaces, corrugated or smooth, and comprise on two opposite ends means for coupling to each other; the two plates define an inner cavity that can be used to place a noise absorbing material.
  • a first objective of this acoustic screen module is to have constructive features meant to allow a compact stacking of the plates that form the modules, where the pressure exerted on the plates in the stack is uniform in its entire surface, reducing the space and costs of storage and transport without risk of deformation of the plates in this position.
  • said features allow reducing the manufacturing costs of the plates.
  • Another objective of the invention is to provide the plates with a configuration that allows facilitating assembly and, no less importantly, disassembling the module for subsequent recycling in a quick, simple, safe manner without the need to use external attachment elements or subsequent additional folding work after the plates are assembled.
  • Another objective of the invention is to provide the coupling means for the plates that form the module with an arrangement and configuration allowing the creation of assembly stops in the formation of the screen by joining successive modules with the features of the invention, or in the assembly position of an initial module on a masonry baseboard.
  • a first feature of the module of the invention is that the first and second plate have profiles with a shape allowing a compact and safe stacking, reducing by up to 600% the space needed to store and transport the plates used in the construction of other known modules, which implies a considerable savings in storage and transport.
  • Another feature is that the plates have identical profiles and this shape coincidence reduces manufacturing costs, as the two plates of the module can be manufactured with the same set of rollers or tools in the same forming machine.
  • the plates forming the module are provided on opposite ends with complementary guiding means with a configuration allowing coupling and separation of the two plates, in a sliding manner, simply by sliding along a longitudinal direction and preventing the relative displacement thereof except in said longitudinal direction.
  • the complementary guiding means comprise in a first end of each plate a longitudinal guide with an inner cavity open at its ends and provided with a lateral opening and, in a second end of each plate a complementary configuration that can be inserted in one of the ends of the inner cavity of the longitudinal guide of the other plate and displaced along the same in a sliding manner, between the coupling and separation positions thereof.
  • the complementary guide means can adopt different shapes without affecting the essence of the invention.
  • the shape coincidence of the plates and the definition on opposite ends thereof of said complementary guiding means in a longitudinal direction allows, when placing a plate in a position and rotating the other 180o, coupling the plates by a longitudinal displacement of one plate with respect to the other, such that the two plates are assembled without requiring additional attachment elements, tools, or tasks for folding complementary ends.
  • the longitudinal guide and the complementary configuration meant to be coupled therein are arranged with one next to the main surface of the corresponding plate and the other laterally displaced from said main surface and joined to the same by a portion of plate substantially perpendicular to the main flat surface, forming a wall that closes the corresponding end of the module in the coupling position of the plates.
  • the longitudinal guide initially has an area substantially perpendicular to the main flat surface, continuing from this area to configure the longitudinal guide in an inner cavity that is related in shape and size with the shape and size of the complementary configuration.
  • This configuration includes the circular shape that the longitudinal guide may have.
  • the longitudinal guides and complementary configurations are in a position jutting out of the closure walls of the opposite ends of the module and a side of said closure walls, forming means to break the acoustic bridge between the module and any support element or stack thereof.
  • the complementary guide means overlap laterally with the adjacent modules, defining a tongue and groove union that laterally closes the effective support area formed by the end walls of said modules and breaks the acoustic bridge, preventing sound waves from passing between said modules.
  • said complementary guide means also ensure the closing of the acoustic bridge between the end wall or base of the first module and a support base of the acoustic screen.
  • the specific shape of the module is such that the block of insulating material, generally rockwool, is placed covering the entire height of the module to form an acoustic barrier in the union of the modules without gaps through which sound waves can pass from one side of the barrier to the other.
  • the block of insulating material generally rockwool
  • the screen created with the modules of the invention is also characterised by its bending mechanical strength against wind pressure, which prevents plasticising of the plates by presenting a continuous coupling between the plates lacking coupling areas with attachment elements that can be deformed by said pressure.
  • the characteristics of the screen formed with the modules that are the subject matter of the invention simultaneously fulfils the following functions: allowing the use o two plates with identical shape to form the module, saving manufacturing costs; allowing the configuration of a tongue and groove union between modules or between the first module and the support base; allowing the lack of gaps or spaces without insulating material in the screen through which sound waves can pass the barrier; allowing a continuous closure between the module plates, not requiring for a correct assembly rivets, screws or subsequent folding after inserting a plate in its complementary plate; and most importantly, the specific shape of the plates allows stacking them in a compact and safe manner saving space in the transport means.
  • module plates can present on their surface a variable number of corrugations of different depth, or have different shapes, which in no way affects the invention disclosed herein.
  • the acoustic screen module comprises two plates ((1a, 1b) with identical profiles, each one of which has a main flat surface (2) and reinforcement waves or corrugations (3).
  • Each one of the plates (1 a, 1 b) has on one of its ends a longitudinal guide (4) with an inner cavity (5) open at the ends and provided with a lateral opening (6), as shown in figure 1 .
  • a complementary configuration (7) to the inner cavity (5) of the longitudinal guide in this case consisting of an end tab, parallel to the main surface (2) of the corresponding plate (1a, 1b).
  • the inner cavity (5) resents a considerably rectangular configuration to receive the cross-section of the complementary configuration (7) of the opposite end.
  • the longitudinal guide (4) begins in an area substantially perpendicular to the main flat surface (2) which is located on one end of the plate, as a continuation of the end of the main flat surface (2), after the last corrugation (3) or in the middle thereof, as shown in Figure 1 , the longitudinal guide extending from this area to configure an inner cavity (5) that has a shape and size allowing to receive the complementary configuration (7).
  • One of the possible shapes of the longitudinal guide (4) described in this embodiment is circular.
  • cross-sections of said inner cavity (5) and said complementary configuration (7) can be any that allow coupling the plates (1 a and 1 b) only by longitudinal displacement thereof, preventing any other relative movement between them.
  • the plates (1 a, 1 b) couple to each other to form the outer surface of the module, by inserting the complementary configurations (7) of each plate (1 a, 1 b) in one of the ends of the longitudinal guides (4) of the opposite plate (1b, 1a); such that simply moving or sliding said plates (1a, 1b) in the longitudinal direction allows coupling them as shown in figure 3 .
  • a block of noise absorbing material such as rockwool is placed inside the module, covering from the top end to the bottom end of each module.
  • one of the plates (1 a, 1 b), specifically that meant to form in the module a side exposed to a noise source, is made from perforated plate.
  • the complementary configuration (7) is separated from the main surface (2) of the corresponding plate and joined to the same by a portion of flat plate (9), without corrugations, which after coupling the plates (1a,1b) forms a closing wall in the corresponding end of the module.
  • the complementary guide means jut out and are displaced towards one of the sides of the complementary guide means allows the successive stacked modules forming a sound barrier, as shown in figure 5 , to be coupled by tongue and groove unions and said guide means to overlap with the adjoining modules or with a lower support base (14), breaking the acoustic bridge in said support or contact areas; the plate segment (9) acting as a support for settling in the upper area of the base (14) or between adjoining modules.
  • the longitudinal guide (4) forms an inner cavity (5) which is related to the dimensions of the complementary configuration (7), where said longitudinal guide (4) is substantially rectangular, forming the walls with two minor sides, one outer side (10) and one inner side (11), and two major sides (12, 13), one of the major sides (12) having a lateral opening (6).
  • the largest (12, 13) in the example shown are perpendicular to the plate segment (9).
  • the longitudinal guide (4) houses the complementary configuration (7) defined in the example of the embodiment in a tab that is an extension of the plate portion (9). This tab is parallel to the flat and perpendicular main surface (2), and therefore to the plate portion (9).
  • the plates (1 a, 1 b) can have on their main surface a different number of corrugations of different depth or amplitude, as this does not affect the essence of the invention.
