Definitions

  • the present invention relates to a wall anchor system for securing an insulation board within a cavity wall, comprising an inner wall, an outer wall and a cavity in between said inner and outer walls in which insulation boards are accommodated.
  • wall anchors are used to connect the inner and outer wall in order to stabilise the building wall.
  • insulation boards are provided. These boards are supported by the wall anchors in the cavity.
  • the wall anchors consists 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 boards are not accurately mounted, and may be dislocated when the wall anchors are bend to fit between the bricklayers of the outer wall.
  • EP 0 469 870 B1 A way of overcoming such problems of permanently protruding wall anchors is known from EP 0 469 870 B1, in which a wall anchor unit for a cavity wall is described, in which a P-shaped anchor is attached to the wall by insertion into a horizontally disposed groove in an insert block, which is mounted in the cavity between the inner and outer wall elements.
  • the anchors are inserted in between two wall elements and further anchors may be secured to the insert block for establishing receipts supporting the insulation in the cavity.
  • the drawback of this solution is that the insulation is not firmly secured, but merely supported.
  • the anchors may be difficult to mount, just as the installation of the insert block is time consuming and involves an extra activity when erecting the cavity wall.
  • this wall anchor unit is also unattractive, since the insulation boards cannot be placed directly on top of each other, since the insert block will space the insulation boards apart. This means that a thermal bridge is established, since the insert block does not have the same thermal insulation properties as the insulation boards.
  • a wall anchor system for securing an insulation board within a cavity wall, comprising an inner wall, an outer wall and a cavity in between said inner and outer walls in which insulation boards are accommodated, said inner wall comprising at least one wall element having at least one retention groove for receiving at least one wall anchor having a protruding rod member extending from the wall element, when the wall anchor is inserted in the retention groove and secured therein by a rotation of the wall anchor, and that at least one insulation board is mounted on said at least one wall anchor.
  • a wall anchor for use in this wall anchor system is provided, wherein the wall anchor consists of an elongated rod member having a retaining member at one end.
  • a wall element for use in the wall anchor system is provided, wherein said wall element includes at least one brick element wherein the retention groove is formed in said brick element.
  • an inexpensive wall anchor system is achieved which is particularly suitable for use in relation to e.g. lime stone elements.
  • all elements can be fitted by the bricklayer.
  • the wall anchor system offer great flexibility in its use.
  • An advantage of using a rod member for the wall anchor is that the anchor or wall anchor rod can be pushed through the insulation and thereby fixes the insulation within the cavity.
  • the insulation can be placed on top of the rod member, if it is not required that the insulation must be fixedly secured.
  • a rod is easier to secure, as there is no directional requirement in its position, since it is not required to support an insulation board along a planar surface, as it is the case with the wall anchor unit known in the prior art.
  • the wall anchor for use in this wall anchor system consists of an elongated rod member having a retaining member at one end.
  • the retaining member may include a resilient blade member on each side of the elongated rod member.
  • this blade member is preferably provided with teeth or similar retention means at the distal end.
  • the wall anchor may be firmly secured in the groove and when it is rotated, any counter-rotation may be prevented by the teeth on the blade ends so that the blades do not loose their grip once the wall anchor is installed in the groove.
  • the wall anchor may be provided with a retaining member, which is a traversely oriented elongated member with a triangular shape.
  • a retaining member which is a traversely oriented elongated member with a triangular shape.
  • the retaining member makes contact with both the front and the back edges of the groove, also if the groove is made up between "half-grooves" of two neighbouring brick elements which are slightly off-set.
  • retaining member is a traversely oriented semi-tubular member made in a resilient material, preferably with convex-shaped blades, so that the retaining member only allows rotation in one direction and resists any counter-rotation once installed in the grooves.
  • the elongated rod member is preferably provided with means for resisting withdrawal of the elongated rod once said rod is cast in mortar of the outer wall.
  • the elongated member is provided with a retention sleeve having a tubular section encompassing the elongated rod and retention members mounted on said sleeve; and that an inner portion of said sleeve is provided with grasping means cooperating with grasping means on at least a section of the elongated rod member for locking the wall anchor in a groove.
  • the wall anchor according to the invention may be provided with a telescopic locking mechanism.
  • a wall anchor system for securing an insulation board within a cavity wall.
  • the wall anchor system comprises an inner wall, an outer wall and a cavity in between said inner and outer walls in which insulation boards are accommodated, said inner wall comprising at least one wall element having at least one retention groove for receiving at least one wall anchor having a protruding rod member extending from the wall element, when the wall anchor is inserted in the retention groove and secured therein by an expanding retaining member of the wall anchor, and that at least one insulation board is mounted on said at least one wall anchor.
  • the wall anchor for use in this wall anchor system consists of an elongated rod member having a flexible retaining member at one end.
  • the retaining member can be "clicked” passed the narrow opening of the groove and expand when it is pressed into the groove, whereby the wall anchor is locked in the groove.
  • the flexible retaining member may be a resilient plate member or a flexible steel plate, whereby the resilient or otherwise flexible plates or blades may elastically bend and thereby compressed when the wall anchor is pressed into the groove and flips out to its normal shape when it is inserted into the groove preventing the wall anchor from falling out of the groove.
  • the elongated rod member is axially shiftable in the retaining member for extending the rod member into the groove and abutting the rod against the back of the groove.
  • the rod may be provided with a threaded portion engaging a correspondingly threaded aperture in the resilient member.
  • the wall anchor can be locked in the groove by screwing the rod further into the groove after the retaining member has been inserted.
  • the wall anchor is clamped into a fixed position in the groove.
  • the wall element includes at least one brick element wherein the retention groove is integrally formed in said brick element.
  • the retention groove may be formed by two adjacently arranged brick element having abutting edges which are provided with correspondingly shaped half-grooves.
  • the brick elements are advantageously provided with edge grooves along at least one side and said sides are adapted to abutting neighbouring brick elements on the inside of the edge relative to the groove.
  • the retention groove is T-shaped.
  • the groove may take any other suitable geometric shape which corresponds to the geometry of the retaining member of the wall anchor for securing the wall anchor therein.
  • the retention groove is oriented in a substantially vertical direction.
  • the grooves may also be generally horizontally oriented, and the brick elements may be provided with grooves in both vertical and horizontal directions or just one of the directions.
  • the at least one brick element may be provided with integrated insulation either at the factory or on the building site.
  • a thinner cavity wall construction may be achieved with a smaller cavity.
  • FIG 1 two adjacent brick elements 1 forming part of an inner wall element is shown.
  • a wall anchor 2 is mounted in a groove 3, which may be formed by the adjoined edges of the two brick elements 1.
  • half-grooves 4 are formed to create a wall anchor receiving T-shaped groove 3 between the two brick elements 1.
  • the brick elements 1 may be integrally fitted with insulation panels 10.
  • the wall anchor consists of an elongated rod-like member 21 and a retaining member 22. Insulation boards 11 are fitted over the wall anchors 2.
  • the brick element 1 may be provided with half-grooves 4 on the edges, which together with a half-groove 4 from a neighbouring brick element 1 (see fig. 1) form a T-shaped groove 3.
  • a T-shaped groove 31 for receiving the wall anchors 2 may also be formed in the cavity side of the brick element 1.
  • a first embodiment of the wall anchor 2 is shown in figures 3a and 3b, where two resilient blade members 23 constitute the retaining member 22.
  • the blade members 23 extend from the anchor rod 21 and are preferably provided with teeth or the like on their distal ends. As shown in fig. 3b, the resilient blades 23 will bend as the wall anchor is inserted into the groove 3 and rotated therein.
  • a second embodiment of the wall anchor 2 is shown.
  • the retaining member 22 is formed as a triangular body, which is sufficiently narrow to be inserted into the groove 3 created by the two half grooves 4 of two neighbouring brick elements 1 (see fig. 5).
  • the wall anchor is rotated, and as shown in fig. 5, the triangular wall anchor retaining member 24 will make contact with both the front and the back of the groove 3 at the contact points 25 (see fig. 5) even if - as shown in fig. 5 - the two brick elements are out of plane.
  • the retaining member 22 is made as a resilient, semi-tubular piece 26 (see fig. 6), which preferably is convex in its shape on one side of the rod and concave in its shape ion the other side.
  • the resiliency will only allow rotation in one direction and resist the retaining member in being rotated in the other direction.
  • a fourth embodiment of the invention is shown.
  • the object of firmly securing the wall anchor in the groove 3 is solved by providing a wall anchor with a tubular sleeve 27 around the base portion of the rod member 21.
  • This sleeve 27 is provided with a retention portion 22a and may be drawn axially away from the retaining member 22 of the wall anchor. Since the rod member 21 and the inner tube of the sleeve 27 is provided with grasping means 28 allowing the sleeve only to be moved in the outward direction.
  • FIG 8 a cross-section of a cavity wall is shown where the inner wall is made up of a number of sand or lime stone brick elements 1, which are provided with grooves 3 on the cavity side.
  • An outer wall 6 is provided and in the cavity 7 between the inner and outer walls, insulation boards 5 are firmly secured to the inner wall by a number of wall anchors 2 of which one is shown in the figure 8.
  • This particular embodiment of a wall anchor 2 shown in figure 8 is provided with a bending 29 in the rod member 21, such as a loop or other bending out of the rotation axis, in order to provide the anchor rod 21 with means for locking it in place in the outer wall once the is placed in a mortar layer between the bricks in the outer wall 6.
  • FIGS 9a and 9b a fifth embodiment of a wall anchor according to the invention is shown.
  • the wall anchor is provided with a flexible retaining member 31, which is inserted into the groove 3, as indicated in position A in fig. 9a and pressed through the narrow outer portion of the groove 3 and into the wider inner portion of the groove 3, as indicated in position B in fig. 9a.
  • the retaining member 31 expands or bends back to its initial position, as shown in fig. 9b, position C.
  • a threaded portion 32 of the retaining member 31 and the elongated rod 21 is provided and the rod 21 is screwed against the innermost groove surface so that the wall anchor is fixed by clamping the wall anchor to the groove 3.
  • the flexible retaining member 31 is preferably a small steel plate with wing-like blades that are bend to an inclined position, so that the shape of the plate 31 only allows axial movement in one direction, i.e. into the groove. It is realised that the flexible steel plate alternatively could be a resilient plastic plate or similar plate-like member, so that the wall anchor cannot be retracted from the groove.
