Definitions

  • the present invention relates to an anchoring rail and a wall anchoring system for insulated outer building walls.
  • Wall anchoring systems of many kinds are well known, e.g. in relation to securing a brick or masonry outer wall to a substrate or inner wall of the cavity wall in a building structure.
  • the structural backup wall i.e. the substrate or inner wall of the cavity is formed of brickwork, a timber frame, steel frame or concrete structure.
  • wall ties or wall anchors are used as point fixing to connect the inner and outer wall in order to provide the necessary structural integrity of the outer building wall.
  • Wall ties or anchors are typically made of metal, plastic or a combination thereof and they may have different shapes, e.g. rod-like or flat plates.
  • said fixing may comprise line objects, like e.g. holding tracks, or brackets (point fixing) as they are for example used in connection with ventilated façade claddings.
  • insulation boards are preferably provided. These insulation boards may be supported by the wall ties in the cavity.
  • the wall ties or anchors may consist of transverse pins, e.g. wire pieces, which are fixed to the inner wall during its construction.
  • the insulation boards are then positioned between these protruding wires or mounted by penetrating the wires through the insulation board. Either way, this has the disadvantage that the insulation boards are not accurately mounted, and may be dislocated when the wall ties are bended to fit between the brick layers of the outer wall.
  • the insulation may break apart, fall off or holes may be punched out causing thermal bridges.
  • a major disadvantage of these protruding wall ties is that construction workers risk getting hurt when working on a site where cavity walls are under construction.
  • the wall ties often are quite numerous, typically 4-6 pieces per square meter, in order to provide the required strength in the construction to withstand the wind load. By bending the wall ties in order to make them fit with the outer wall construction, the strength of these wall ties is somewhat reduced and there is a risk of some wall ties breaking off.
  • Building requirements generally prescribe a maximum elongation or compression of the wall anchors of 1 mm in the cavity wall. This calls for a high concentration of wall anchors per wall area.
  • the wall ties also constitute thermal bridges in the thermally insulated cavity wall construction, and from this perspective, as few wall anchors as possible is preferred, just as fewer wall anchors reduces the building costs involved, and the installation time is shorter.
  • a masonry anchoring system with an anchoring rail for wall anchor ties is known from US 7,469,511 .
  • the anchoring rails are secured to the inner wall structure by fasteners and possibly accompanied by adhesive.
  • Anchor ties are coupled to the anchoring rail as they bite into the slot formed in the anchoring rail.
  • This system has still the disadvantage that the wall anchor ties constitute thermal bridges in a thermally insulated cavity wall.
  • a masonry coupling system comprising an anchor for use in commercial and residential construction.
  • the anchor comprises a channel body connected to two walls.
  • a second wall of the two walls has a proximal end and a distal end, the proximal end being projected substantially perpendicular to the channel bottom and the distal end being projected toward the channel bottom.
  • a wall anchor is disclosed, which is made of a sheet material that is cut into a blank and mounting portions, i.e. the mounting flange and the insulation gripping projections are bent out of the plane.
  • This wall anchor is mounted on the inner wall after it has been raised, preferably together with fitting the insulation slabs.
  • the outer tip of the wall anchor is moulded into the mortar between the bricks during the raising of the outer wall.
  • GB-A-2 111 095 discloses a wall anchor made of a sheet material which is cut into a blank and the insulation gripping projections are bent out of the plane.
  • This wall tie is moulded into the mortar between the bricks during the raising of the inner wall.
  • the outer tip is moulded into the mortar between the bricks during the raising of the outer wall.
  • This wall tie is only useable when the cavity wall includes an inner wall made of bricks that are stacked with an adhesive mortar in between.
  • this wall tie must also be bended to fit into the mortar layer between two brick layers. This could cause the insulation boards to be bended or dislocated.
  • WO2014/187726 an innovative new insulating wall construction is disclosed, where columns made of high density mineral wool fibres are provided as load-carrying columns between which insulation panels are provided.
  • This wall structure is advantageous as it is substantially thermal bridge free and provide excellent thermal insulation characteristics.
  • an outer cladding can be mounted directly onto this wall structure, there may be circumstances where it is desired to use this wall structure in a cavity wall building construction, for instance with a masonry outer wall constituting the outer protective cover of the building.
  • the columns of this wall construction does offer the possibility of mounting for instance wall ties directly onto the exterior facing mounting elements of the columns, but such mounting, in particular when an insulation layer is provided in the cavity of the cavity wall, may damage the wall ties as they become loaded and unloaded due to variations in wind pressure and wind suction forces acting on the outer wall and the softness or resilience properties of the mineral wool insulation material.
  • US 3,903,671 relates to linings for building structures, such as walls, and provides means for attaching panels to a supporting wall surface or structural framework.
  • an anchoring rail and a plurality of fasteners according to a first aspect of the invention. Further this object is also achieved by a second aspect of the invention, which is a wall anchoring system for an insulated outer building wall comprising
  • the present invention is concerned with insulated outer building walls, e.g. cavity walls of buildings, comprising a substrate or inner wall, an insulation layer and an outer wall constituting the outer protective cover or cladding layer of such walls.
  • an anchoring and insulation arrangement with an anchoring rail profile, e.g. from steel metal, fixing and securing the insulation in front of the substrate or inner wall of a building, and at the same time securing the outer wall via fixings that are locked in the anchoring rail profile.
  • the anchoring rail profile according to the first aspect of the invention is made special in its shape, so that the rail profile fulfils two functions at the same time:
  • the fixing is fixed/secured by screws or similar means directly onto the anchoring rail profile, specifically its outer surface opposite the base portion.
  • the design of the line fixing is thus adopted to fit the special shape of the anchoring rail profile.
  • the wall anchoring system and the anchoring rail profile according to the invention is advantageous since by the invention it is made possible to provide a wall anchoring system which can be mounted directly onto the insulation, such as mineral wool fibrous insulation, of e.g. a cavity wall, although the insulation is flexible/compressible and not supporting the load-bearing capacity of the system as such.
  • the insulation such as mineral wool fibrous insulation, of e.g. a cavity wall
  • the insulation is flexible/compressible and not supporting the load-bearing capacity of the system as such.
  • the anchoring rail profile according to the first aspect of the invention is made special in its shape, and in a first embodiment the side portions extending perpendicular to the wall plane of the base portion. Furthermore, preferably the anchoring rail profile is made of one strip of material, such as a metal or metal alloy, in particular steel or aluminium or their respective alloys, which is bent into shape. This allows for an easy and cost-effective manufacture of the anchoring rail profile.
  • the anchoring rail profile may advantageously be provided with a thickness of the material between 0.5-2.0 mm.
  • the retention portions are inwardly bent clamping flanges on the distal sides of the side flanges opposite the base portion.
  • intermediate flanges may be formed between inwardly bent clamping flanges and the distal sides of the side flanges opposite the base portion, said intermediate flanges being substantially parallel to the base portion.
  • the anchoring profile may be formed with retention portions as inwardly projecting protrusions on the middle sections of the side flanges. This shape may be supplemented with outwardly projecting positioning flanges at the distal sides of the side flanges opposite the base portion, said outwardly projecting flanges being substantially parallel to the base portion.
  • Other shapes of the anchoring rail profile according to the invention may also be provided.
  • the insulation layer preferably comprises mineral wool fibrous panels, preferably with a density of 30-250 kg/m 3 , more preferably of 50-150 kg/m 3 .
  • the wall anchoring system may be used in connection with normal types of insulation, such as the mineral wool with densities within this range.
  • the at least one anchoring rail is preferably provided in a groove on the exterior side of the insulation layer, said groove preferably being machined into the surface of the insulation layer.
  • the anchoring system does not take up additional space and the cavity wall thickness can be reduced.
  • the anchoring rail is provided with a vertical orientation.
  • orientations may be chosen if circumstances favour such other orientations.
  • the fastener is a screw.
  • other types of fasteners may also be used.
  • the fixing has a gripping end and an outer wall mounting end, where the gripping end is preferably provided with T-shape so that the fixing is adapted for being introduced into the slot of the anchoring rail and locked therein by turned the fixing after introduction.
