Definitions

  • the invention relates to a flexible crack-spread-preventing device comprising a web-type joining layer for joining a bearing face of a structure to a rigid covering layer to be provided thereon.
  • a rigid covering layer e.g. a protective layer such as an ornamental layer or tile surface
  • a protective layer such as an ornamental layer or tile surface
  • GB-A-786614 discloses a flexible crack-spread preventing device comprising a flexible polyethylene film or a flexible kraft paper layer being fixed and fitted between bearing face of a concrete structure and a covering layer.
  • This device presents the disadvantage that tearing forces only act upon one film or kraft paper layer so that the crack preventing properties of this device are often insufficient, or are lost after a short period. Moreover, it is impossible to adhere a covering layer to such a polyethylene film as polyethylene does not present adhesion properties.
  • the crack-bridging action depends on the quality which happens to exist in the adhesion to the bearing face. With good adhesion the crack-bridging action will generally be limited to less than 1 mm, depending on the thickness of the elastic covering layer. Only if the adhesion is poor can good crack bridging can be obtained, since the fibrous web above the crack can only stretch with it if it is not adhering to the underlying bearing face.
  • the object of the invention is now to provide a flexible crack-spread-preventing device which better prevents cracks which occur in a bearing face of, for example, concrete, masonry or wood, such as a roof, floor or wall of a building structure, such as a building, bridge or pool, from spreading into a rigid covering layer provided thereon and joined thereto, while in addition a covering layer once fitted can be removed more easily.
  • the device comprises at least a lower fixing layer separated by a thin, flexible, essentially non-adhering separating layer, from an upper stretchable fixing layer, while on either side of the separating layer and extending through it breakable bridges join together the lower and upper fixing layer.
  • a non-adhering separating layer in this case is understood to mean a layer which does not adhere to the adhesive agents used for bonding the lower fixing layer to the bearing face and the upper fixing layer to the covering layer.
  • the breaking strength between the lower fixing layer, which is preferably in the form of a non woven layer, and the upper fixing layer is expediently controlled by the number of breakable bridges between these layers. In this way, a covering layer once fitted can easily be removed with the use of a small number of breakable bridges, while this is much more difficult with a large number of bridges.
  • the bridges extending on either side of the separating layer are expediently formed by needle punching from the lower to the upper fixing layer through the separating layer.
  • the flexible crack spread preventing device With the use of the flexible crack spread preventing device according to the invention it is possible to join a bearing face well to a rigid covering layer through the fact that the lower fixing layer, preferably a non woven layer, is bonded with a synthetic resin to the bearing face, while at the other side the covering layer, for example a tile surface or a covering layer made from synthetic resin and filler particles, is placed on the upper fixing layer, and crack formation in the bearing face still does not spread into the covering layer.
  • the lower fixing layer preferably a non woven layer
  • the filler particles can be, for example, powder particles, such as quartz powder particles, or granular particles or granulate particles, such as gravel particles.
  • the thickness of the lower non woven is expediently as low as possible, in order to reduce the consumption of resin for the bonding of this non woven layer to the bearing face.
  • the upper fixing layer can also be a woven fabric or a glass mat, as a result of which a greater tensile strength is obtained, and in particular a higher modulus, so that the covering layer itself is subjected to less stress.
  • a synthetic resin is selected for bonding the lower non woven layer to the bearing face and the upper fixing layer to the rigid covering layer, and this resin can be selected freely depending on the further use requirements.
  • Suitable bonding agents are unsaturated polyester resins, polyurethanes, polymethyl methacrylates or epoxy resins, or formulations based on such resins. However, formulations of other plastics and cement and/or plastic mortars are also suitable.
  • a number of bridges will give way under the influence of the shearing stress, so that a local delamination takes place. Consequently, the then free part of the upper fixing layer can stretch over the delaminated area and can thus absorb the crack width in the bearing face.
  • the extent of delamination can be controlled by suitable control of the number of breakable bridges, the tensile strength of the upper fixing layer, and the elasticity thereof.
  • the invention also relates to a covering layer construction on a bearing face of a structure with a rigid covering layer provided thereon and a flexible crack-spread-preventing device (1) comprising a web-type joining layer for joining a bearing face of said structure to said rigid covering layer between them, as known from GB-A-786614 being characterized in that a flexible crack-spread-preventing device is present between covering layer and bearing face, said device comprising at least a lower fixing layer separated by a thin, flexible, essentially non-adhering separating layer, from a stretchable upper fixing layer, while on either side of the separating layer and extending through it breakable bridges join together the lower and upper fixing layers, and lower and upper fixing layer are joined to the bearing face or the covering layer.
  • Such a covering layer construction is particularly suitable for providing, for example, a covering layer of filler particles bound by synthetic resin as a protective and/or decorative layer on floors, roofs and walls of a building.
  • the invention relates to a method for providing a rigid covering layer on a bearing face of a structure using a flexible crack spread preventing device comprising a web-type joining layer fitted and bonded between them, as known from GB-A-786614, being characterized in that a device is placed on the bearing face, said device comprising least a lower fixing layer separated by a thin, flexible, essentially non-adhering separating layer, from a stretchable upper fixing layer, while on either side of the thin separating layer and extending through it breakable bridges join together the lower and upper fixing layer, and one of the fixing layers is bonded with a bonding agent to the bearing face, and the other fixing layer is bonded also with a bonding agent to a rigid covering layer provided thereon.
  • Fig. 1 shows a flexible crack spread preventing device 1, comprising a lower fixing layer, in the form of a non woven layer 5, and a upper fixing layer 6, separated from each other by a thin, flexible, non-porous separating layer 4, in the form of a polyethylene plastic film. This plastic film does not adhere to thermosetting resins.
  • the upper fixing layer 6 is also a non woven material made of plastic fibres.
  • the non woven layer 5 is expediently made of plastic fibres weighing about 50 g/m2, while the non woven layer 6 weighs about 50 - 250 g/m2.
  • the non woven layer 6 is expediently approximately 2 mm thick, while the thickness of non woven layer 5 is selected as low as possible. These values are, however, given only by way of illustration.
  • Fig. 2 shows what effects occur with crack formation in a floor 2 of a building on which the joining material 1 is fixed by means of a synthetic resin which has penetrated into the lower non woven layer 5.
  • a covering layer 3 of filler particles such as quartz powder particles bound by epoxy resin is bonded to the upper fixing layer 6, which is also a non woven.
  • the number of needle punches forming fibrous bridges in the device 1 was 20/cm2.
  • the upper stretchable fixing layer 6 has come away from the lower non woven layer 5 through delamination and can itself stretch in order to prevent the crack 8 which has formed from spreading into the rigid covering layer 3.
