Definitions

  • the invention relates to a box window.
  • Box windows as double-shell components with window sashes arranged essentially parallel to one another have been known for a long time. Newer developments in the area of box windows are, for example, shown in the DE 20 2014 106 055 U1 , DE 20 2016 101 405 U1 , DE 20 2017 104 656 U1 , EP 2 947 252 A1 disclosed.
  • Known box window has an outer window level with outer window sashes, which are separated by an outer window frame part and at least one of which is tiltable. There is also an inner window level with inner window sashes, which are separated by an inner window frame part. One of the inner window sashes can be tilted in a horizontal direction offset from the tiltable outer window sash.
  • a vertical separating device is arranged, by means of which the box space is divided into two box sub-spaces. The separating device provides sections with different passage values for an air flow between the box compartments, so that a U-shaped air flow can result in the box room. This allows improved sound insulation to be achieved.
  • a box window is described in which a window frame of the outer window designed as a plastic frame and the window frame of the inner window are connected to one another by means of a box frame.
  • the box frame is a metal frame educated. This allows improved thermal insulation to be achieved.
  • a sound-insulated window arrangement in the manner of a box window is known, in which the box frame is designed with sound-absorbing frame elements.
  • a ventilation opening is provided in the inner window sash, which allows ventilation flow when the inner window sash is closed. This creates a sound-insulated window arrangement that allows ventilation in a simple and efficient manner.
  • a box window with a composite construction in which the inner frame, the inner sash frame and the box frame are made of wood, while the outer frame and the outer sash frame are made of metal profiles, is made of the EP 2 947 252 A1 known.
  • a ventilation window which has a frame, an outer wing arranged in connection with the frame and an inner wing arranged in connection with the frame. A space is arranged between the outer wing and the inner wing.
  • the ventilation window has a ventilation device installed or installable within the frame or on the surface of the frame on the side of the gap, which extends into the gap and which has at least one fresh air duct for passing fresh air from outside to the ventilation device through an inlet located in the frame on the outside and from the ventilation device further to the interior as supply air through at least one outlet arranged in the frame on the side of the interior.
  • an exhaust air duct is provided for leading exhaust air from the interior to the ventilation device through at least one inlet in the frame on the inside and from the ventilation device further outwards as exhaust air through at least one outlet arranged in the frame on the outside.
  • the ventilation device does not enable ventilation of the space between the inner wing and the outer wing.
  • the DE 77 29 730 U1 discloses a window consisting of a sash frame and a frame and two glass panes arranged parallel to each other at a distance with an air duct for discharging room air to the outside.
  • the upper horizontal leg of the frame has a first channel that runs upwards from the space between the two glass panes and then towards the room.
  • the space between the two glass panes communicates with a second channel located below the window sash frame, which extends horizontally essentially from one lateral end to the other end of the window, there angled by 180 degrees in the opposite direction horizontally to close to the first lateral end of the window runs and flows outwards.
  • a window arrangement with an openable external window arranged together in a building opening and an internal window facing the inside of the building, which can be opened and closed independently of the external window.
  • the inner window is optionally coupled to the outer window and can be opened and closed together and is a preferably double-glazed insulating window.
  • the external window is equipped with ventilation channels that connect the cavity between the two windows with the environment.
  • the object of the invention is to create a box window that reduces or even eliminates at least some of the deficits mentioned.
  • the box window according to the invention has an outer window level with at least one outer window arranged in an outer window frame, an inner window level with at least one inner window arranged in an inner window frame and a box frame connecting the outer window frame and the inner window frame.
  • the inner and outer window levels are arranged essentially parallel to one another, while the box frame is aligned essentially perpendicular to the two window levels.
  • the inner and outer window levels together with the box frame form a substantially cuboid hollow body in the manner of a “box”.
  • the cavity is also referred to below as a box space.
  • the cuboid body can be cube-shaped.
  • the box frame is formed from a lower box frame element, two side box frame elements and an upper box frame element, which together with the outer and inner window levels enclose the box space.
  • Location information used in this description such as: B. top, bottom, inside, outside etc. refer to the intended installation situation of the box window in or on a building facade.
  • the inner and/or outer window can be formed in one piece or consist of several window elements, which together form the inner or outer window and are arranged in the inner or outer window plane.
  • the inner and/or outer window can preferably have a light transmittance of at least 82%. As a result, a high level of light transmission can advantageously be achieved, so that good Lighting conditions in the interior of the building behind the box window can be achieved.
  • the inner and/or outer window can be single or multi-glazed.
  • An embodiment is preferred in which the inner window is double-glazed and the outer window is single-glazed, as this allows a high level of light transmission with good sound and heat insulation to be achieved.
  • the openable window element can be used as a rotating window element, which opens vertically via a laterally vertically arranged axis of rotation, as a folding window element, which can be opened outwards or inwards at the bottom using a fitting attached at the top, as a tilting window element, which can be opened outwards at the top using a fitting attached at the bottom can be opened inside, as a swing window element, which opens horizontally via a centrally horizontally arranged axis of rotation, as a pivoting window element, which opens vertically via a centrally arranged vertical axis of rotation.
  • the window element can also be designed as a tilt-and-turn window element.
  • At least one window element of the outer window can also be designed to be openable. Thanks to the possibility of opening, improved ventilation can be achieved.
  • the box window can also be cleaned more easily.
  • one or more inner surfaces of the box frame can have a light-reflecting and/or white coating. This allows the light entry into the building interior behind the box window to be further improved.
  • the box window can in particular be designed in such a way that it is at least partially arranged outside the building facade when used as intended.
  • the outer window level is also located outside the building facade.
  • the box room is at least partially arranged outside the building facade and forms a bay window.
  • This construction method avoids a reduction in the usable interior space, as the box window does not protrude into the interior, but outwards. It is also not necessary to coordinate the depth of the building envelope and the width of the box frame.
  • the box window can therefore be used flexibly. Retrofitting existing buildings is also possible, e.g. B. by replacing a conventional window with a box window.
  • the box window also has a ventilation opening arranged in the box frame.
  • a ventilation opening arranged in the box frame.
  • several ventilation openings can also be present in one or more box frame elements.
  • At least one ventilation opening is arranged in a side box frame element of the box frame and enables ventilation of the box space.
  • ventilation opening By means of the ventilation opening, ventilation of the box space can advantageously be made possible even when the windows are closed, so that the formation of condensation in the box space can be reduced or even completely avoided.
  • the interior of the building behind the box window can be ventilated by outside air flowing through the ventilation opening first into the box room and from the box room via the open inner window.
  • Arranging the ventilation openings outside the insulated building shell or building facade is also advantageous from a fire protection perspective.
  • At least one of the ventilation openings can be designed such that it is permanently open. Further preferably, all ventilation openings are designed in such a way that they are permanently open. This allows forced ventilation to be achieved that is independent of the user. Summer overheating and moisture damage to box windows due to inadequate ventilation can be reduced or even completely avoided.
  • At least one ventilation opening can be arranged in a lower box frame element of the box frame.
  • a ventilation opening in the side box frame element can be arranged above a box frame center line that horizontally divides the box frame into two equally sized box frame sections.
  • each of the two side box frame elements there can be a ventilation opening in each of the two side box frame elements.
  • the two ventilation openings arranged in the side box frame elements can be arranged at the highest possible point of the side box frame element. If a ventilation opening is also arranged in the lower box frame element, the thermal buoyancy can be used for ventilation, which creates air circulation in the box space in such a way that outside air flows into the box space through the ventilation opening in the lower box frame element and out of the box space through the two in the side box frame elements arranged ventilation openings flows back outside. This can further improve the ventilation of the box space.
  • the ventilation openings can have a circular cross section with a diameter of less than 0.1 m. Such a diameter improves fire protection and advantageously enables compliance with fire protection regulations.
  • the ventilation openings can be equipped with a protective grille made of a non-combustible material, such as. B. aluminum or steel sheet, be covered.
  • the protective grilles can, for example, have fixed slats.
  • insect protection e.g. B. made of a metal wire mesh.
  • the protective grilles can advantageously prevent contamination of the ventilation openings, e.g. B. prevent the penetration of insects, birds, etc. by dirt particles.
  • the penetration of precipitation, e.g. B. in the form of rain, snow, hail, etc. can be reduced or avoided.
  • the box window can be designed as a self-supporting construction.
  • Self-supporting means that the box frame is firmly connected to the inner and outer window levels and forms a self-contained, ready-to-assemble component.
  • the box window is stable in itself and forms its own facade building block.
  • the box window can be designed to be dimensionally stable and liftable with a lifting device at two or four load-bearing points.
  • the box window can advantageously be prefabricated as a whole, so that installation into the building facade can be carried out quickly with little technical effort.
  • Existing buildings will also be retrofitted thereby simplified.
  • the box window can be lifted to its destination using a crane using a few anchor points and secured there.
  • a factory-prefabricated, self-supporting box window can be created, which can be delivered to the construction site ready for assembly and in principle already functional as a separate and self-contained component.
  • the self-supporting construction is also advantageous for fire protection reasons and also has a positive effect on the traffic loads inside the box.
  • the box frame can be designed as a concrete frame or wooden frame.
  • a concrete frame version e.g. B. made of reinforced concrete, contributes to improved weather resistance.
  • a box window with a low fire load can be created.
  • a wooden frame design can be advantageous for thermal insulation reasons.
  • the outer window and the inner window can be arranged essentially parallel to one another, the distance between an outside of the inner window and an inside of the outer window being at least 0.5 m, preferably at least 0.55 m.
  • Such a design can advantageously achieve very good sound insulation due to the very high airborne sound insulation, particularly at low frequencies, due to the distance between the inner and outer windows and the resulting very high airborne sound insulation.
  • the inner window and the outer window act as masses between which the air in the box interior acts as a spring, so a double-shell mass-spring-mass system is formed.
  • the box window can also be used in areas with high levels of noise, e.g. B. can be used in busy areas, industrial areas, etc. or, depending on the legal requirements, residential development is made possible in such areas.
  • Baffles are additional construction elements in the form of glass panes arranged in partial areas of the building facade, which are attached independently of the window behind them.
  • a characteristic feature of baffle plates is the ventilation gap that always remains free, which can be as wide as 0.1 m. Such constructions are used to reduce the wind effect on the sun protection, to reduce the noise impact on the actual window at high outside levels or to create fall protection.
  • the box window can have an outer window handle arranged on the outer window frame, the outer window handle being arranged below a window frame center line which horizontally divides the outer window frame into two equally sized window frame sections.
  • the outer window handle can preferably be arranged in a lower third of the outer window frame.
  • the inner window handle arranged on the inner window frame can also be arranged below a window frame center line that horizontally divides the inner window frame into two equally sized window frame sections.
  • the outer and inner window handles can be arranged at the same height.
  • the lowered height of the outer window handle makes opening the outer window easier from an ergonomic point of view, as an adult person standing on both legs inside the building can easily reach the outer window handle without any aids.
  • At least one window element of the inner window can be tilted inwards and/or outwards.
  • the tiltable window element can be assigned an opening limiter, by means of which a tilting width of the tiltable segment can be limited. This means that the noise input into the building interior can be controlled and any regulations regarding noise input can be adhered to.
  • the box window can have a condensate drain arranged in the lower box frame element of the box frame.
  • the condensate drain can be integrated into a ventilation opening arranged in a lower box frame element of the box frame.
  • the ventilation opening arranged in the lower box frame element of the box frame can serve both for ventilation and for condensate drainage, which advantageously only requires one opening in the lower box frame element, with which both functions can be fulfilled. This is also advantageous from a fire protection perspective.
  • the condensate drain can be used to remove any condensation or rainwater that may form in the box space, e.g. B. driving rain, are removed so that water accumulates in the Box space is prevented and thus moisture damage as well as a reduction in the transparency of the window and thus the light entry into the building interior can be reduced or avoided.
  • the box window is designed as a bay window protruding from the building facade, the condensate drain can create a direct connection to the surroundings, so that the condensate can drain directly into the surroundings and other elements that serve to drain the condensate, such as. B. hoses are not required.
  • the box window can have a sound absorber arranged on an inner surface of a box frame element of the box frame.
  • the sound absorber can be arranged on an inner surface of an upper box frame element.
  • the sound absorber serves as noise protection in that noise penetrating into the box space from outside can be absorbed using the sound absorber.
  • the sound absorber can be made of a white and/or light-reflecting material, so that the light absorption is low and the light entry into the building interior is not or at most slightly influenced by the sound absorber.
  • the following advantages can be achieved at the same time: compliance with the immission guidelines for commercial noise (0.5 m in front of the inner window), sufficient sound insulation of the partially opened window to comply with the relevant noise levels in connection with traffic noise Indoor level of 30 dB(A) in the building interior and adequate ventilation of the building interior.
  • Ventilation openings are arranged in a flow-optimized manner at the base and in the two upper side areas. This enables thermal buoyancy with inflow and outflow openings and wind-induced air exchange by using the windward/leeward side to ventilate the box space and for inflow into the interior of the building behind it.
  • the box window can also be used to combat sports noise, leisure noise and aircraft noise. It enables you to sleep at night with the window tilted while at the same time complying with the requirements of emission guidelines, indoor levels, and all relevant ventilation levels of DIN 1946-6: 2019-12 - all of which are user-independent.
  • Fire protection concerns can be taken into account by making the box frame of fire-resistant quality reinforced concrete, by designing the side ventilation openings as very small openings with a diameter of less than 10 cm within a component, by placing the ventilation openings outside the insulated building envelope and by providing the ventilation openings with weather protection grilles be provided with fixed slats made of non-combustible material.
  • a high level of light transmission and thus a high level of light entry into the building interior is made possible by using few panes of glass, e.g. E.g. single glazing on the outside and double glazing on the inside, glasses with high light transmission, e.g. B. a light transmittance of 82% or more can be used, the inside of the box frame is made white and light-reflecting and a white material is selected for the sound absorber.
  • compositions when used in a series of two or more elements means that any of the listed elements may be used alone, or any combination of two or more of the listed elements may be used. For example, if a composition is described as containing components A, B and/or C, the composition A alone; B alone; C alone; A and B in combination; A and C in combination; B and C in combination; or A, B, and C in combination.
  • the building facade 28 can, for example, be made of reinforced concrete with a thickness of 200 mm, to which a pressure-resistant mineral facade insulation with a thickness of 180 mm is applied on the outside and a mineral plaster with a thickness of 15 mm is applied on both sides.
