Definitions

  • THIS INVENTION relates to a method of and apparatus for building construction using a series of tubular elements which are locked together to construct walls, floors, ceilings or roofs for, inter alia, buildings, swimming pools and earth retention walls.
  • the present invention resides in a method of building construction characterized by the steps of :
  • each tubular element comprising a plurality of plates inter ⁇ connected by a plurality of spaced bands outwardly directe from the sides of the plates with respective apertures being defined' between adjacent pairs of said bands; (ii) placing the tubular elements in substantially side by-side relationship so that at least one of the bands of one side of a first tubular element overlaps a respective band of the adjacent side of an adjacent tubular element and enters a respective aperture of the adjacent tubular element; and (iii) locking the tubular elements together.
  • the present invention resides in a building construction characterized by: a plurality of tubular elements in substantially side-by-side, relationship, each of the tubular elements comprising a plurality of plates interconnected by a plurality of spaced bands outwardly directed from the side of the plates, and respective ' apertures defined between adjacent pairs of the bands; and means to lock the tubular elements in said sub ⁇ stantially side-by-side relationship wherein at least one of the bands of one side of a first tubular element overla a respective band of the adjacent side of an adjacent tub u lar element and enters a respective aperture of the adjacent tubular element.
  • tubular element will be used to describe and define a substantially hollow element which in end view is substantially circular, elliptical or polygonal with three or more sides (e.g. hexagonal, octagonal) and/or a combination of these, e.g. one plate is semi-circular in end view and a second plate is semi-elliptical in end view.
  • the locking means to effect step (iii) may include longitudinal rods passing between overlapped bands to prevent adjacent tubular elements from being separated; at least one transverse rod passing through the tubular elements provided with bearing plates which engage the end elements; slots formed in the bands which are engaged by the bands of the adjacent elements; and/or a combination of these. Longitudinal and/or reinforcing rods may be provided in the structure to increase its strength.
  • the tubular elements may be filled with concrete, soil or rock, or with insulating foam or fibrous material. Normally such filling will place the plates in tension but, if a plate is concave, the plate will be placed in compression. If an expansion joint is required, one or more of the elements may be left empty or only be partially filled.
  • the bands may be formed integrally with the plates or may be fixed thereto by, e.g. welding, riveting, clipping or other suitable fastening methods or by the use of suitable adhesives.
  • the bands may be formed by rings to which the plates are releasably or securely fixed, e.g. each tubular element comprises a pair of plates and a series of rings which are engaged by the plates.
  • the plates may be solid, i.e. in sheet form, or may have holes punched therethrough or may be in the form of mesh to which a liner or covering sheet is applied internally or externally.
  • a covering sheet may be provided to cover one or more of the tubular elements.
  • a building wall could comprise a series of tubular elements sandwiched between aluminium exterior cladding and a timber veneer interior lining.
  • adjacent elements may be vertically offset, while for non-linear structures (e.g. curved walls) , the apertures are not diametrically aligned across the elements but may be spaced apart at angles of, e.g. 60°, 90° or 120°.
  • a particular type of element can be modified to enable construction of curved walls having a wide range of radii of curvature.
  • the elements may be positioned in the footings trench before the concrete for the footings is poured.
  • Reinforcing rods in the footings may extend transversely through the elements or may extend longitudinally up through the elements for connection, e.g. to the roof structure to act as cyclone bolts.
  • FIG. 1 is a perspective view of a part of a wall assembled from tubular elements according to the present invention
  • FIG. 2 is a partly exploded perspective view of a tubular element according to a modified form of the invention

  • the edges 18 of the plates 12. are aligned so that filling material placed in one of the tubular elements may enter the adjacent elements but may not escape from between the plates 12 of the adjacent elements.
