  • the wall structure comprises strips which connect between sections of the wall and pegs which reinforce the wall structure to the ceiling and/or floor.
  • a method for forming a wall structure comprising of the following steps, which may be carried out in various sequences wherein the casting of the concrete must always be the final step. ;
  • tie elements are employed for securing the coating layer to the core, said tie elements are installed in the process of applying said coating.
  • the present invention provides a load bearing wall structure which is constructed in a layered manner wherein insulating and reinforcing elements are sandwiched between an external coated panel and an internal panel.
  • a wall structure comprising;
  • An outside coating layer (1) Said layer protects the external panel (2) from mechanical damage and may further provide insulation against permeation of water and humidity.

  • the support structure (4) is preferably constructed of horizontal and vertical beams.
  • suitable materials for said support structure include steel, aluminum or wood, preferably steel.
  • the steel reinforcement (5) can be of various forms suitable for providing structural strength to the wall structure.
  • the steel reinforcement (5) is a network of steel rods interweaved. Said network is positioned at a fixed distance, parallel to the external panel (2) and within the hollow space in the core of the wall.
  • the fixed distance between the steel reinforcement (5) and the external panel (2) is maintained by rigid spacers (6), which are positioned horizontally between said external panel (2) and the steel reinforcement (5).
  • the length of the spacers (6) is adjusted to the required distance between the external panel (2) and steel reinforcement (5).
  • Said spacer (6) can be made of metal, wood, plastic or any suitable material for this purpose.
  • the steel reinforcement may be in the form of steel beams positioned vertically within the core and optionally connected by other steel connectors.
  • the tie elements (7) which are preferably made of steel, are connected at one end to the outside coating layer (1) and at the other end to the internal panel (3) and/or support structure (4).
  • the function of said tie elements (7) are to secure the outside coating layer (1) to the core of the wall structure.
  • Various types of concrete (8) may be used for casting into the hollow space, as may be appreciated by the skilled artisan.
  • the characteristics of the concrete are such that it is free flowing, self leveling, rapid hardening with negligible retardation, improved anti-segregation properties and excellent workability.
  • Such concrete is also known in the art as Self Compacting Concrete (SCC). Said properties are important for ensuring that the concrete when cast, flows freely to fill all of the hollow space such that there are no voids where the concrete did not settle in. Furthermore, said properties are important for providing a wall structure of the required technical features, e.g. strength.
  • the wall structure may be constructed to include an opening e.g., window or door, by creating the required size opening in the external panel, support structure and internal panel and then building a frame on the internal perimeter of the opening.
  • Said frame may further function as door post or mounting frame on which the door or window is mounted.
  • the wall structure further comprises a strip (9) which connects between sections of the external panel.
  • Said strip (9) provides reinforcement to the wall structure and provides improved insulation.
  • Said strip (9) is preferably of rigid material.
  • suitable materials for the strip are cement board, gypsum board and the like.
  • the wall structure comprises a peg (10) which reinforces the floor and/or ceiling of the building to the wall.
  • Said peg (10) is embedded in the ceiling/floor and connects to the wall structure.
  • the peg (10) may connect to any part of the wall structure, e.g. to the concrete (8) or preferably into the external panel (2).

  • the wall structure further comprises insulating material (Fig. 4;(11),(14)) in the seam between the ceiling/floor and the wall structure.
  • insulating material are polystyrene and polyurethane.
  • the side of the ceiling/floor which faces the outer side of the structure may be coated with an external coating (Fig.4;(12)).
  • the seam between the ceiling and the internal panel of the wall structure is hidden by a decorative molding (13).
  • the seam between the floor and the wall structure is hidden by the floor sub-base (15) on which the flooring finish (16) is mounted.
  • the overall thickness of the complete wall structure is dependent upon the dimensions of the elements of the wall and the distances between them, all of which may be adjusted to the functional and structural requirements.
  • the thickness of the wall structure is preferably between 10 cm to 50 cm. As may be appreciated by the skilled artisan, at certain wall thicknesses reinforcements may be required.
  • tie elements (7) are employed for securing the coating layer (1) to the core, said tie elements (7) are installed in the process of applying said coating.
  • the external panel (2) is constructed of building blocks, preferably of AAC blocks.
  • the function of the vertical insulation layer is imparted onto the AAC blocks which display improved insulating properties. Accordingly, the need for a separate insulating layer is obviated.
  • the external panel provides all three functions of a concrete forming panel, bearing the outer coating layer and insulation.
  • wiring, plumbing and other building elements may be installed in the wall before the final installation of the internal panel (3) and the casting of the concrete (8).
  • the inside surface of the internal panel (3) is coated with a coating such as paint, wall paper or any suitable finish.
  • a strip (9) which connects between sections of the external panel is inserted into the external panel (2) in a longitudel orientation, hence, providing insulation and rigidness to the seams of the wall structure.
  • the strip (9) is installed by making a cut along the outer profile of the external panel of the wall sections, which are to be connected, and then sliding the strip into the cut.
  • suitable materials for the strip are cement board, gypsum board and the like.
  • the wall structure is reinforced to the floor and/or ceiling of the building by a peg (10) which is embedded in the ceiling/floor and connects to the wall structure.
  • the peg (10) may be inserted such that it connects to any part of the wall structure, e.g. to the concrete (8) or preferably into the external panel (2).
  • the peg (10) may be of any suitable material, e.g. steel, wood, preferably steel.
  • insulating material may be applied to the seams between the ceiling/floor and the wall structure.
  • insulating materials are polystyrene and polyurethane.
  • steps of the present method have been described in a particular order, it is within the scope of the present invention to alter the order of the construction steps. Further more, certain steps may be carried out at various locations, and not necessarily at the construction site. For example the coating layer of the external panel may be applied prior to transferring the external panel to the construction site.
  • the present wall structure and method for the construction thereof are advantageous in that they provide a wall with load bearing capability, improved insulation and at a relatively minimal wall thickness.
  • the use of AAC blocks of improved insulation compared to conventional concrete blocks obviates the need for further insulation layers in the wall, hence maintaining minimal wall thickness.
  • the incorporation of the reinforcement in the concrete core imparts load bearing capabilities to the wall, thus rendering the wall suitable for the construction of high rise building as well.
  • the use of gypsum board for the inside surface provides for easier and faster finishing and further obviates the need for plastering the walls as in conventional building.
  • the present wall structure and method of construction facilitate the incorporation of pre-fabricated building elements into the construction process.
  • the flexibility in the construction steps provides a building process which is faster than conventional methods and has less rate determining steps which may impede the process.
