Definitions

  • the object of the invention is an aluminium carpentry system used for manufacturing such structures as windows, doors, etc., with improved thermal insulation and providing corrosion protection of the hardware fittings operating inside the hardware grooves.
  • Known carpentry systems can be divided into three main types, due to the material used to form main profiles, i.e. the profiles forming a frame and a sash.
  • the first type are wooden systems, wherein main profiles are made of milled wood or wood composites.
  • Wooden sash or frame profile is a monolithic structure made of a block of wood or a block of glued laminated timber. All gaskets and hardware fittings are mounted in a specially profiled channels made in the main profiles.
  • the second type are PVC systems, wherein main profiles consist of extruded PVC [poly(vinyl chloride)]. Each sash or frame profile is formed as a single multi-chamber structure with a uniform chemical composition. All gaskets and hardware fittings are mounted in profiled seats of the PVC main profile.
  • PVC carpentry significant disadvantages include: high thermal expansion (in particular of dark colours), low stiffness of the profiles (while using other reinforcement materials results in deterioration of thermal insulation properties), generally limitation to single-storey constructions, lower durability of profiles and surfaces, lack of resistance to heat and fire and harmfulness of the thermal decomposition products during the fire.
  • the third type of carpentry systems are aluminium systems.
  • a frame and sash profiles have a similar structure, consisting of an external aluminium profile and an internal aluminium profile, connected via plastic thermal strips.
  • the connection is realized by clamping the profiles on edges of the thermal strips.
  • Thermal strips located in the central part provide the required thermal insulation to the profiles (and as a result to the aluminium carpentry systems).
  • they provide static rigidity to the entire system. Thermal strips are used only in the aluminium systems, because - as indicated above - main profiles in the wooden and PVC carpentry are monolithically formed from a material having the required thermal insulation.
  • Both the external and the internal aluminium profiles are usually painted with powder coatings, anodized or coated in another way, which serves both aesthetic reasons and protection of the profiles from corrosion.
  • the external sash profile together with a glazing, gaskets and other elements mounted therein, protects from weather conditions, such as precipitation, sunshine.
  • the internal profile of the sash has specially designed seats for mounting glass fixing profiles (glazing clips) and seats in form of hardware grooves, constituting channels for fixing working hardware fittings.
  • Hardware fittings provide the ability to move the sash relative to the frame in a certain way, such as opening, tilting, sliding and blocking the sash in a desired position relative to the frame.
  • hardware fittings are made of steel elements protected with anti-corrosion coatings.
  • aluminium systems include: relatively low thermal expansion, high rigidity without the need for additional reinforcements, high durability of the surface, wide choice of available coating colours, ability to be mounted outside the construction in the thermal insulation plane, ability to realize large and complex multi-storey structures and to produce fire-resistant structures.
  • the aluminium carpentry systems While the PVC and wooden carpentry systems generally belong to opening systems, i.e. unified and mass-produced window and door designs, the aluminium carpentry systems, manufactured in more complex processes, requiring a large number of material and design factors to be taken into account, are primarily used to design complex architectural and engineering structures, such as e.g. glazing of multi-storey office buildings or shopping malls, or realising single-storey tall structures (over 3m) or durable window and door structures resistant to multiple opening and closing.
  • complex architectural and engineering structures such as e.g. glazing of multi-storey office buildings or shopping malls, or realising single-storey tall structures (over 3m) or durable window and door structures resistant to multiple opening and closing.
  • the type of hardware fittings used imposes a standardized shape of the hardware groove, which must be used in the sash profiles.
  • hardware fittings in the aluminium systems operate in an aluminium groove formed in the internal profile of the sash, in the PVC systems - in the groove formed in the PVC profile and in the wooden systems - in a groove milled in the wooden or wood composite profile.
  • the aluminium systems use both types of grooves, while the PVC and wooden systems use mainly PVC groove type.
  • PL 223656 B1 discloses a window consisting of a frame and a sash, in which both the frame and the sash consist of an external profile connected by means of thermal strips to an internal profile.
  • the internal profile of the sash on the side facing the frame has a euro type hardware groove.
  • form-fitted gaskets mounted on the frame at the side facing the sash completely fill the space between the thermal strip of the frame and the thermal strip of the sash, thereby protecting the structure interior from water intrusion, as well as contributing to the improvement of the window system thermal insulation.
  • a simpler solution with a single profile gasket filling the space between the frame and the sash is disclosed for example in EP 2128371 B1 .
  • EP 2 374 977 A2 in addition to the two gaskets system in the space between the frame and the sash, in order to increase thermal insulation a use of additional coating of cell elastomer or polyethylene foam is proposed together with glazing gaskets having extended skirts penetrating into this coating, jointly sealing the seat in the sash, wherein the glazed unit is embedded.
  • a common method is merely to expand aluminium profiles (or more precisely - thermal strips) to get the best thermal insulation (the larger the thermal strip, the better the Uf coefficients).
  • Such action has significant disadvantages, manifested especially in case of profiles with a width of approx. 95 mm or more. These include for example worse accuracy and stability and complicated design (too many components).
  • BE 1 018 057 A3 discloses an aluminium carpentry system comprising a frame, a sash movably mounted in the frame, a glazing unit, glazing clips and at least one hardware fitting according to the preamble of claim 1.
  • the aim of the present solution was to overcome the above-mentioned problems, associated with the use of prior art aluminium carpentry systems, by providing a system with enhanced thermal insulation without deteriorating the operating parameters, such as high stiffness, good static stability, the system further allowing for protection of hardware fittings from corrosion and improving their operation comfort.
  • the further aim was the abandonment of using a central gasket so as to speed up the production of prefabricated window structures, at the same time providing the aluminium system with optimum water resistance and air permeability, both in the space under the window panes and at the interface between the external profiles of the sash and the frame.
  • the object of the invention is an aluminium carpentry system comprising a frame, a sash movably mounted in the frame, a glazing unit, glazing clips and at least one hardware fitting with the features of claim 1.
  • substantially U-shaped referring to the cross-sectional shape of hardware groove should be understood as covering both the basic U-shape as well as the forms including some additional small elements, e.g. projections facing inside the U-shape or extension of one or both of the free ends in a direction perpendicular or oblique relative to the U-shape arms.
  • the term "hardware groove” means a seat in which the hardware fitting moves slidably, whereby the hardware groove walls directly contact the hardware fitting.
  • plastic thermal strips of the frame and the sash means a strip that is closer to the system interior, that is a space between the frame and the sash.
  • exital means, in turn, a strip that is more distant from this space, which in case of plastic thermal strip of the sash means a strip that is closer to the glazing unit, and in case of plastic thermal strip of the frame - a strip that is closer to the contact area of the frame with a structure surrounding the system of the invention.
  • a hardware groove is set in a recess in the internal profile of the sash.
  • the internal plastic thermal insulation of the sash is integrated with a substantially U-shaped hardware groove set in the recess in the internal profile of the sash.
  • the recess in the internal profile of the sash has a substantially U-shaped cross-section and the hardware groove entirely fills the recess.
  • the internal plastic thermal strip of the sash forms one wall of a substantially U-shaped hardware groove, and the other walls of this groove are formed by the surfaces of the recess in the internal profile of the sash.
  • each of the glazing and the rebate gaskets of the system is made of the same material and have the same cross-sectional shape.
  • each of the glazing and the rebate gaskets of the system consists of a mounting part made of a hard material and clamped permanently in the gasket seat of the frame, the sash or the glazing clip, respectively, and of a sealing part made of a soft elastic material, wherein both gasket parts are permanently connected together.
  • the central insulation element is in form of a plastic moulding, which is form-fitted in corresponding projections at the frame surface from the side facing the sash in a closed position of the system, wherein between the plastic moulding surface and the plastic thermal strip of the sash there is an air gap, the outlet of which from the outside of the system in cross section view is closer to the sash than its outlet from the inside of the system.
  • the plastic moulding is mounted through clicking or sliding into guides formed by corresponding projections at the frame surface from the side facing the sash in a closed position of the system, and the width of the air gap is from 2.5 to 4 mm.
  • At least one gasket groove is formed in the plastic thermal strip of the sash at the side of a glazing unit, and that at least one window pane seal is fixed in said groove.
  • the window pane seal consists of a mounting part made of a hard material and clamped in the seal seat of the plastic thermal strip and a sealing part made of a soft elastic material, wherein both seal parts are permanently connected together.
  • the glazing unit consists of three glass panes separated by spacer strips.
  • thermo foam In other preferred embodiment between the plastic thermal strips connecting the external and the internal profile of the frame and/or of the sash there is a thermal foam.
  • the hardware groove at least partially, and preferably entirely made of plastic provides a covering of the metal hardware fitting (as a rule made of stainless steel) from contacting aluminium surfaces of the recess in the internal profile of the sash. This protects against formation of galvanic areas, and at the same time prevents from formation of thermal bridge between the hardware fitting and the profile, thus improving the thermal insulation of the entire system.
  • the hardware groove according to the invention may be realized in three basic variants:
  • the plastic hardware groove is made of plastic showing high thermal insulation [in particular having a thermal conductivity coefficient ⁇ (lambda) from 0.5 to 0.03(W/m ⁇ K)], not entering into chemical reactions with aluminium profiles and steel parts of the hardware fittings.
  • the solution according to the invention is clearly changing tendencies and design trends in aluminium carpentry systems, in particular window and door systems.
  • Continuous plastic element provides the sash with excellent thermal and static properties and protects the hardware fitting entirely [option (a)] or partially [option (b)] from contacting with the aluminium of the internal profile of the sash.
  • the solution of option (c) also provides full protection from occurrence of galvanic areas and thermally separates the hardware fitting metal from the aluminium of the internal profile of the sash.
  • known internal plastic thermal strips of the sash are used, which makes the modification of known systems require merely adjusting the structures of the internal profile of the sash to receive the plastic hardware groove of the invention.
  • Another aspect of the invention is the use of external rebate gaskets form-fitted on the frame external profile edge facing the sash.
  • the external rebate gaskets provide tightness of the connection of the external profile of the sash and the frame, protecting the interior of the aluminium carpentry system from precipitation water and cold air access from the outside. They allow to abandon standard central gaskets used in known aluminium systems. Instead of them it is possible to use plastic mouldings, plugged or slid in appropriate projections/guides formed in the profiles and/or the plastic thermal strip of the frame, said mouldings being cheaper in terms of material cost, and above all in terms of manufacturing of prefabricated window structures.
  • the plastic mouldings significantly improve the thermal characteristics of the system, and also prevent the intrusion of excess condensation and precipitation water into the building. The narrow gap between the plastic thermal strip of the sash and the plastic moulding effectively breaks the stream of cold air, preventing it from getting into the building.
  • Another aspect of the invention is the use of the same gasket type as both the external and internal glazing gasket and the external and internal rebate gasket, which significantly simplifies manufacturing of prefabricated structures containing the system according to the invention, although it requires appropriate changes to the design of the frame and sash, including above all the glazing clip profile and the space between the sash and the frame (see the previous aspect associated with the use of the plastic moulding).
  • a further aspect of the invention is the use of gaskets permanently clamped in the profiles of the frame, the sash and the glazing clips.
  • aluminium profiles are offered on the market as separate items, and the gasket assembly is realized by the producer of the window joinery. Due to bi-material structure (a mounting part made of a hard material, clamped in the gasket seat, and a sealing part made of a soft elastic material) the gaskets according to this aspect of the invention may exist in form integrated with the profile.
  • window pane seal mounted in the thermal strip.
  • the window pane seal is bi-material, i.e. has a hard mounting part, slid into the thermal strip seat and a soft sealing part.
  • the seal may replace or supplement typically used sub-glazing foam. It prevents the penetration of condensation and precipitation water and air into the inside of structure in the glazing areas. This is particularly important in aluminium window systems exposed to high wind pressure on the surface of the glazing (e.g. at high floors of the buildings), which might cause temporarily slightly weaker pressure of the external glazing gasket on the glass, which in turn increases the risk of precipitation water and/or outside air intrusion into the space under the window panes.
  • Fig. 1a and b illustrate cross-sections of two types of hardware grooves used in sash profiles of aluminium carpentry systems: fig. 1a shows a EURO type hardware groove (aluminium), and fig. 1b - a PVC type hardware groove. Regardless of the name, both types of grooves in known aluminium carpentry systems are made of aluminium as integral parts of the sash profile.
  • Fig. 2 shows a cross-section of the fragment of the prior art aluminium carpentry system, comprising a frame 1, a sash 2 movably mounted in the frame 1, a glazing unit 3, a glazing clip 4 and a hardware fitting (not shown in the drawing).
  • the frame 1 consists of an external profile 101 and an internal profile 102 that are connected via plastic thermal strips 103, 104.
  • the sash 2 consists of an external profile 201 and an internal profile 202, which are connected via plastic thermal strips 203, 204, wherein the internal profile 202 of the sash 2 has a recess forming a hardware groove B at the side facing the frame 1 in a closed position of the system, and on the opposite side it has a clamping groove 7 for fixing the glazing clip 4.
  • the central gasket A contacts the projection on the internal plastic thermal strip 204 of the sash 2.
  • the hardware fitting (not shown in the drawing) is slidingly placed in the hardware groove B.
