Definitions

  • This invention relates to a system designed to be fitted to the outer skin of a double-skin facade in the place that would be occupied by one of the bricks of the outer skin, creating a channel for ventilation to the inner cavity of the facade, which can be opened or closed to convenience depending on weather conditions.
  • This device significantly improves the energy efficiency of the facade by allowing the passage of air in summer to cool the interior while in winter the passage can be closed to shut out the exterior. The device is opened and closed from inside the building.
  • the device is configured on the basis of a casing with openings for the air that can be opened or closed at will by means of movable shutters operated by a rotating rod.
  • the casing can have different shapes to suit the shape of the facade, depending on the material the skins are made of, their thickness and the intermediate inner cavity.
  • This invention will apply primarily in the manufacturing industry for construction materials, such as vents and similar.
  • the facade is the most important element for the energy efficiency of the building.
  • the proper design and implementation of the facade will significantly reduce the energy consumption of the building, saving in climate-control in the inhabitable interior areas.
  • facade which has been and is still widely used, consists of two skins with insulation and an intermediate air cavity.
  • this type there are many variants adapted to solving particular problems. However they all share the fact that they are made with an outer skin, with or without facing, an intermediate air cavity with insulation and an inner skin to close off the design. On occasions, the intermediate air cavity is completely closed off and on others it is in contact with the exterior through openings provided accordingly.
  • ventilated facade which comprises an open structure fixed to the facade with a bearing capacity that prevents the sun from affecting the enclosure of the building directly while allowing air to circulate between the facing and the facade.
  • Facades with an intermediate cavity insulated from the exterior are very suitable in cold climates, since the intermediate air cavity provides insulation from the cold outside.
  • the intermediate air cavity provides insulation from the cold outside.
  • hot climates as the air in the cavity is not renewed, it reaches high temperatures that are transferred to the inner wall and from there into the building.
  • facades with air cavities open to the exterior the situation is reversed: they work well in hot climates, but perform poorly in cold climates because the air cavity offers no insulation.
  • the appearance of a device that makes it possible to modify the intermediate air cavity of a double-skin facade is both desirable and useful, remaining closed in winter and with the option for being opened in summer to renew the air inside.
  • the device would also be desirable for the device to be valid for use not only on newly constructed facades, but also on existing facades by means of a simple operation consisting of drilling a hole and then sealing the joints.
  • Ventilated facades with motorized mechanisms that move part of it to close the unit in winter and obtain the necessary insulation against the cold are known in this field. However, it is not considered that the said mechanical system has similarities with the proposed device beyond their similar purpose.
  • Adjustable facade facing with support frame for a building This consists of an adjustable facade facing for a building with an outer facing formed by panels arranged one after and/or above the other, regulated by an adjustment device between closed and open positions, characterized in that it comprises an inner facing attached at a distance from the outer facing and consists of one or more wall parts, because the adjustment device is positioned on a support frame that can be fixed to the building, composed of vertical and horizontal support parts and rotation devices to adjust the panels because, in their rotated position and during the rotation process, they are on the outer side of the support frame and because the inner facing is attached by the support parts to the outer facing for support.
  • This invention comprises a system for building facades that has little to do with the device proposed herein, except for its purpose of making it possible to change the structure of the facade as required, although this is solved by a complex construction that is considerably more expensive than the simple installation of the device described herein.
  • GB 2338497 (MOLYNEUX PROD LTD) Cavity ventilation and drainage weep vent for fitting between bricks in a mortar joint. This describes a device formed by two parts fitted together and sliding on each another, intended to be incorporated in a double-skin facade.Its main function is ventilation, but it can also be used for drainage.Although it has similarities with a part of the device described herein, it cannot be opened or closed to allow or prevent the passage of air from outside to inside the cavity and acts as a permanent opening that does not solve the aforementioned problem of adapting to the different weather conditions of each season.
  • US 3062278 (INDORANTE, SAM) describes a device for the passage of air between the exterior and interior of a home through the wall.
  • the device has inner and outer walls with the corresponding regulated enclosures.
  • This device provides ventilation for the interior of the home from the exterior, with the option for closing the passage of air from inside the home.
  • it does not solve the problem of ventilating the inner cavity of a double-skin facade since it cannot be operated if installed only on the outer wall of this type of facade.
  • ES 2364008 (INNOVACIONES CERAMICAS EDIAM, S.L.) Ventilated facade system.
  • This is a facade building system using two types of parts: some to create continuous air cavities inside the enclosure; and others to provide air inlets and outlets to and from the cavities.
  • This construction system lacks the option for opening and closing the inner cavity at will and is also limited to newly built facades since it cannot be fitted to existing facades.
  • the invention described in US 848917 (MCELLIOT EDWARD JAMES, CIMMERY EDVARDO A) describes a very similar block system, where the continuous cavity has a fan that blows air through it.
  • ES 0201018 U (01.11.1975)
  • DONALD DONALD
  • a ventilation duct device intended to be fitted between the corresponding bricks of successive rows of them. This consists of a hollow rectangular sleeve fitted to the joints between the bricks of the facade to form an opening to allow the passage of air from the exterior to the inner cavity of a double-skin facade, where said sleeves contain a device that prevents the passage of water.Furthermore, it is not possible to open or close them from inside the home and they are configured solely as a means to provide ventilation to a facade instead of traditional facade-ventilation bricks.
  • the proposed ventilation device for double-skin facades comprises a casing with air passages at one end leading to the exterior and at the other end for the air to enter the air cavity of the facade.
  • the said casing can have very different shapes depending on the geometry of the facade. It can be of the same size as one of the bricks in the wall (the most common case) and can be used on facades where the outer wall is made using prefabricated concrete panels, where the casing would be cylindrical to fit a bushing hole, which would be equally suitable for installing the device on an existing facade.
  • the air inlet openings will have filtration traps to prevent the entry of insects and birds, etc.
  • the air inlets from the outside will have a shutter mechanism to close and seal the said inlet, operated by means of a rod that will cross the inner skin of the facade such that, inside the building, there will be a visible device for controlling the rod.
  • the mechanism for closing the shutters may have many different shapes and may consist of a rack-and-pinion to operate the shutters by moving them laterally, a threaded shaft that moves the shutters longitudinally along the device or any other method valid for the aforementioned function.
  • the shutter drive mechanism will therefore not influence the essence of the invention.
  • the rotating rod may have a telescopic section to adapt to possible changes in the width of the wall due to changes to the facing or other circumstances. It will also be covered by a sleeve to ensure that it is protected and safe from jamming caused by the penetration of foreign material when turning the device to open or close the shutters.
  • the configuration of this invention can be changed so that the shutters are opened and closed using methods other than a rotating rod, such as a rod which, when moving longitudinally or radially in relation to the axis of the rod itself, acts directly on the shutters to open or close them.
  • a rotating rod such as a rod which, when moving longitudinally or radially in relation to the axis of the rod itself, acts directly on the shutters to open or close them.
  • Any system for opening or closing shutters that uses a rod to operate the shutters from inside the building is considered merely a design choice and does not alter the essence of the invention
  • the casing may be built in two separate parts, with one fitting on the other to adapt the length of the casing to the thickness of the skins of the wall to which it is fitted.
  • the inside of the casing will slope slightly at the bottom to avoid the accumulation of rain or condensation water.
  • Water drainage holes are fitted at the bottom on the outer end of the casing.
  • the device its use for ventilating the interior of a facade is simple: to increase air circulation by convection as the warmer air inside comes into contact with the cool air outside, one of these devices has to be fitted at the bottom of the wall and another at the top.
  • the invention is configured on the basis of a casing (1) that acts as the main support of the device and, on brick facades, takes the form of one of the bricks (15).
  • the said casing (1) will have openings to the exterior (2) at the end on the outer skin of the facade and an opening to the interior (3) leading to the inner cavity between the two skins.
  • the casing (1) will also have a movable part (16) with the aforementioned opening to the interior (3).
  • the openings that lead to the exterior (2) of the casing have a shutter (9) to close them off.
  • the said shutter (9) is moved by a rod (4) which, when rotated, operates a rack (10) and pinion (11) unit connected to the shutter.
  • the rack (10) moves on a guide (13) positioned inside the casing (1) and has several bearings (12) to help it move.
  • the lower internal plane of the casing (14) has a slope downwards towards the exterior to drain any water entering into the device. The water will be drained through drainage holes (6).
  • the rod (4) will have a telescopic section (8) to modify its length to accommodate any possible change in the final thickness of the wall on which it is installed.
  • the rod (4) will be set in a sleeve to prevent it from jamming when turned.
  • the rod (4) is rotated from the interior of the wall by means of a control (5), which is the only visible part from inside the building.
  • Figure 4 shows a different configuration of the device, where the casing (1) has a cylindrical shape to fit a bushing hole made in a prefabricated concrete panel or, in the case of an existing facade, where a through-hole would be made to install the device.
  • the rod (4) also runs through the interior of the casing (1).
  • the shutters (9) it is directly attached to the shutters (9) so that they all rotate at the same time and open or close the openings to the exterior (2).
  • the openings that lead to the interior (3) are regularly distributed over the surface of the casing (1).
  • the shape of the casing (1) can be changed simply to adapt it to the type of facade on which it is to be fitted and does not alter the essence of the invention in any way.
  • an air current must be created, providing the inner cavity with an air inlet and outlet by fitting the device.
  • one device must be fitted at the bottom of the wall with the opening towards the interior (3) facing upwards. At the top, the opening towards the interior (3) must be facing downwards to create a circuit for the passage of air from the exterior to the interior and vice versa.
  • the manufacture of the casing (1) in two parts to configure a telescopic casing means that, depending on whether the device is to be fitted at the top or bottom of the wall, the opening towards the interior (3) of the cavity can be positioned facing upwards or downwards simply by extending and turning the telescopic section (16) of the device. Accordingly, the shape of the area in which the casing is fitted (1) in relation to the telescopic section (16) will be symmetrical to a horizontal plane located at the midpoint of the height of the casing (1).
