  • Publication number: 20120042585
    Abstract: The invention relates to a prefabricated wall element for a tower construction, essentially of concrete, arranged to form one of several wall portions of a building formed by circumferential shell portions of one of several shell portions stacked on each other, wherein the wall element is constituted by a substantially flat sheet portion comprising a pair of opposite sides intended to run substantially horizontally in the building and a pair of opposite sides intended to run in a direction forming a predetermined angle to the horizontal plane in the building, and along which sides the wall element includes compressive and tensile load absorbing pillar portions and is intended to be connected to adjacent wall elements. The invention also relates to a tower construction, a mobile antenna system and a wind power plant.

  • Publication number: 20110311775
    Abstract: At least one embodiment of the present invention relates to a constructional element for use in building structures. In at least one embodiment, the element includes a least a first and a second side extending substantially parallel to each other and includes: a continuous board; a continuous insulating layer with substantially the same size as the board, the insulating layer is aligning, and bounded to, one side of the board; a first and a second load bearing beam of high performance concrete extending along the first and second side; at least one elongated load bearing element of high performance concrete extending between the first and second load bearing beam; wherein the elongated load bearing element and the first and second load bearing beam are extending in grooves in the side of the insulating layer facing away from the board, the load bearing element, and first and second load bearing beams are separated from the board.

  • Patent number: 4730431
    Abstract: A flanged beam with a web structure formed of a wire or strip-like member (2) bent to zigzag, meander or wave configuration, the bending spots (3) thereof being attached to the flanges (1). The specific feature of a beam performed according to the invention is that at least one flange (1) incorporates a flange section extending alongside this flange. The flange section, which is made of another material than the rest of the flange, is embedded in the flange and is cast to form a unit with it and with the bending spots (3) of the wire or strip-like member (2) which spots are connected with the flange.

  • Patent number: 4578912
    Abstract: A foundation for cellarless houses comprises a foundation wall (6) whose underside is disposed on a level below the ground surface (4) surrounding the house (1) and serves to support the house and, together with a bearing floor structure (5), also to define a bottom space (12) in the area above the ground on which the house is erected. The floor structure (5) has a lower portion which is air permeable in order, via the floor structure, to permit supplying air of substantially room temperature to said bottom space (12) from which the air is thereafter evacuated. According to the invention, said lower portion exclusively consists of a thin air-permeable web (11), and a heat insulating layer (21) for the foundation is placed directly on the ground (20) underneath the floor structure.
