Definitions

  • the present invention relates broadly to a wall panel and method of fabricating the same, particularly to modular precast wall panel system.
  • the existing dry wall system uses plasterboard installed on a grid of steel or aluminium tracks and studs.
  • the relatively high cost is the limitation in using the dry wall system.
  • a precast hollow core wall offers a cheaper alternative to the dry wall system but weight is the limitation.
  • the heavy weight of the wall reduces productivity and safety, increases damage and wastage, and impedes adjustability and hence accuracy of installation.
  • both the dry wall and hollow core wall can only be erected to limited heights without lintels and their surface strength for anchorage is also low.
  • the limitation in height makes the use of these two wall systems very unproductive and expensive for high walls.
  • the low surface anchorage strength also limits the installation of heavy fixtures on the wall. This is particularly the case in the construction of industrial buildings where headroom is high and heavy fixtures are installed onto the walls.
  • US 2008/01 15442 Al discloses a composite sandwich wall panel that constitutes of two fine sand gypsum or concrete panels with polystyrene panel disposed at the centre. Although this wall system is light, it has limitation in height. Furthermore, the use of the polystyrene panel, which is a fire hazard material, precludes the use of the wall panel as fire rated walls.
  • the existing light modular wall panels cannot be erected to greater heights productively without the need of lintels, and have weak surface strength for installation of heavier fixtures.
  • Embodiments of the present invention provide a wall panel and method of fabricating the same that seek to address at least one of the above problems.
  • a wall panel comprising a concrete core having opposing front and back faces and opposing side face; and a fibre membrane bonded to each of the front and back faces.
  • a method for fabricating a wall panel comprising the steps of providing a concrete core having opposing front and back faces and opposing side face;, and bonding a fibre membrane bonded to each of the front and back faces.
  • FIG. 1 shows a schematic sectional diagram illustrating modular fibre-concrete-fibre (FCF) sandwich wall panel according to an example embodiment.
  • FCF modular fibre-concrete-fibre
  • Figure 2 shows a schematic 3 -dimensional diagram of the modular FCF sandwich wall panel of Figure 1.
  • Figure 3 shows a flow-chart illustrating a method for fabricating a wall panel, according to an example embodiment.
  • Embodiments of the present invention seek to meet the need of a lightweight precast wall panel, a high precast wall panel and a wall panel with high anchorage strength in building construction.
  • Providing a lightweight wall panel increases safety, productivity, ease of adjustment for accuracy and reduces damage and wastage.
  • a high wall panel eliminates the need for lintels and greatly increases the productivity reducing construction time significantly.
  • the present invention relates to a sandwich wall panel comprising two layers of fibre membrane, each bonded on opposite faces of a precast wall core.
  • the fibre membrane can be made of any fibre that has sufficient modulus and tensile strength and can be meshed into a membrane.
  • the precast wall panel can be any panel that is made of concrete or other suitable materials with sufficient strength and durability.
  • the sandwich wall panel of example embodiments of the present invention has the advantage of high bending strength and surface strength catering to the need of higher and thinner panels with good anchorage on the wall face to address the shortcomings of the current wall systems.
  • the agent to bond the membrane to the precast wall core can be combined with fine sand if bonding with plaster or skim coat is required.
  • FIGS 1 and 2 show a schematic sectional diagram and a schematic 3-dimensional diagram respectively, illustrating a wall panel 100 according to an example embodiment.
  • the wall panel 100 comprises a precast wall core 102, with hollow sections or cores 104 in this embodiment. However it is noted that no hollow cores may be provided in different embodiments.

  • the wall panel 100 which may also be described as a modular wall panel, can have a height that may vary from very small to around 6000mm, with one preferred height being about 3000mm.
  • a width of about 600mm and thicknesses of about 70mm, about 90mm or about 100mm are preferred examples, but notwithstanding, the overall size of the wall panel in different embodiments can vary according to specific functional requirements of particular buildings, as will be appreciated by a person skilled in the art.
  • Side faces 1 14, 116 of the wall panel 100 are free from fibre membrane, i.e. at the side faces 1 14, 116, the surfaces of the precast wall core 102 are exposed. This facilitates the joining of adjacent wall panels 100 during construction of a wall, for example a partition wall.
  • the side faces 1 14, 1 16 may comprise structures for facilitating the joining of the wall panels 100, such as mating ridges 1 15 for corresponding grooves (compare 117) in the side face of an adjacent wall panel, or vice versa.
  • the precast wall core 102 can be made of a material with compressive strength ranging from about 2 MPa to about 50 MPa in some example embodiments, and with elastic modulus ranging from about 5 GPa to about 100 GPa.
  • the compressive strength and elastic modulus of the material in composite action with the fibre membranes 106, 110 provide the improved strength to the sandwich wall panel to resist the bending forces the wall is subjected to during handling, installation and in service, in particular when provided in larger heights.
  • the compressive strength of the material also advantageously provides the necessary strength to the wall panel 100 to resist axial load during handling, installation and in service.
  • the material also provides the strength for anchorage of fixtures, which may be further enhanced by the bonded fibre membranes 106, 1 10.
  • the material of the precast wall core 102 can be concrete made using Ordinary Portland cement (OPC) or other binders, and fillers that constitute fine and/or coarse natural, synthetic or recycled normal or lightweight aggregates. Autoclaved aerated or foamed concrete can also be used to form the precast wall core in different embodiments.
  • the precast wall core 102 can be either cast using form works or can be extruded using slip forms with the concrete. Any other materials suitable for use in e.g. partition walls with the material properties stated above can also be used to form the precast wall core in different embodiments.
  • the precast concrete core may be fabricated using techniques understood in the art, and may for example be fabricating using the method and apparatus as described in published PCT application WO20071 14795 Al.
  • the fibre membranes 106, 1 10 for the sandwich wall panel 100 can be made from fibres of glass, carbon, polyvinyl alcohol (PVA), polypropylene, Kevlar kenaf (natural fibre) or other materials, weaved in a regular or random orientation.
  • the fibre can be continuous in length or chopped into small strands, in which case the membrane is sometimes referred to as chopped strand mat.
  • the tensile strength of the fibre membranes 106, 110 is dependent on the height of the wall panel 102, which may also be referred to as the length of the wall panel depending on its orientation, for example during transportation of the wall panel).
  • fibre membranes 106, 1 10 with mass ranging from about 5 g/m 2 to about 50 g/m 2 can be used for an about 3 metres long wall panel 100
  • fibre membranes 106, 110 with mass ranging from about 20 g/m 2 to about 200 g/m 2 can be used for an about 6 metres long wall panel 100.
  • the tensile strength and elastic modulus of the fibre ranges from about 20 to about 3000 MPa and about 50 GPa to about 1000 GPa respectively.
  • the tensile strength and elastic modulus, in combination with the bonding agent, and in composite action with the precast wall core 102, advantageously provide the necessary strength to the sandwich wall panel 100 to resist bending during handling, installation and in service.
  • the agent to bond the fibre membranes 106, 110 onto the front and back faces 1 12, 108 of the precast wall core 102 can be made from epoxy resin, or any polymer, mineral or cement based material.
  • the agent can be premixed with fine sand of size between about 0.5mm and about 1.5mm, for example to facilitate plaster or skim coating.
  • the bonding process of the fibre membranes 106, 110 onto the precast wall core 102 in one example embodiment segregates the fine sand to the top surface leaving the interface between the precast wall core and the fibre membranes 106, 110 substantially free of any fine sand.
  • the fine sand at the top surface of the membranes 106, 110 preferably prepares the surface of the sandwich wall panel 100 for plaster or skim coat to adhere thereto.
  • premixing of the bonding agent with fine sand or the like is optional and will e.g. not typically be used if the wall surface does not require finishing with plaster or skim coat, or if the plaster and skim coat can adhere onto the fully set bonding agent used in various embodiments.
  • the bonding agent preferably strongly bonds the fibre membranes 106, 110 onto the precast wall core 102 to effect composite action of the fibre-concrete-fibre.
  • the bonding agent advantageously serves to sufficiently bond the fibre membranes 106 110 onto the faces 108, 1 12 of the precast wall core 102 to facilitate the composite action of the fibre membranes 106, 1 10 and the concrete of the precast wall core 102 in resisting bending actions or forces.
  • the fibre membranes 106, 110 in addition to providing flexural strength to the sandwich wall panel 102, can advantageously ads other benefiting features to the wall system.
