Abstract:
Method for manufacturing a concrete panel wherein a mould is provided, where said mould has a design corresponding to the desired concrete panel, and where: a) a flowable (homogenous) mixture comprising a high strength concrete mixture, said high strength concrete having a compressive strength of more than 65MPa and a lightweight granular aggregate and optionally add-mixtures is prepared; b) the flowable mixture is placed in the mould; c) the mould is vibrated, whereby the lightweight material will migrate towards the surface; d) the concrete is allowed to harden and cure either in the mould or after de-moulding.
Abstract:
Roofing element (1) having upper (10) and inner (20) shell sections made from high strength concrete, where said shells are arranged on either side of an insulating core (30), where one or more reinforcement lattices (40) are arranged, said reinforcement lattice (40) being embedded both in the upper (10) and inner (20) concrete sections.
Abstract:
Method of manufacturing a high strength concrete element in a main mould (1), where the main mould (1) comprises at least two mould surfaces (2,3,4), where said at least two mould surfaces (2,3,4) are arranged at relative angles between 15° and 165° relative to each other where one mould surface (3) is substantially horizontal, comprising the steps of: • - spraying an outer skin layer (20) of reinforced high strength concrete mix against the mould sides (2,3,4); • - pouring a first backfilling (30) of a high strength concrete against the substantially horizontal surface (3) covered by the outer skin (20) • - placing an insulation layer (40) in the still wet backfilling (30) • - pouring a second backfilling (30') of a high strength concrete in the space between the insulation (40) and the outer skin layer (20) and the first backfilling concrete (30) • - allowing the outer skin layer (20) and the backfillings (30,30') to harden and chemically react hydraulically or pozzolanically together, to form one monolithic layer, where the insulation (40) is connected to the now hardened backfilling (30,30'); • - removing the mould (1).
Abstract:
Roofing element having upper and inner shell sections made from high strength concrete, where said shells are arranged on either side of an insulating core, where one or more reinforcement lattices are arranged, said lattice being embedded both in the upper and inner concrete sections.
Abstract:
The present invention relates to an elongated pipe insulating unit (1 ) comprising superposed first and second insulating material slabs (30, 35), each defining a respective major surface (26, 28), the unit (1 ) including at the interface between said slabs (30, 35) at least one area (5) for receiving a pipe (10, 12). In accordance with the invention the unit (1 ) further comprises securing means (40) for securing said first slab (30) to a building part, such as a wall or a ceiling, in a fixed position with the major surface (28) of said first slab (30) being adjacent said building part, the unit (1 ) further comprising fastening means (15) for securing said second slab (35) to said first slab (30).
Abstract:
Modular high strength concrete sandwich panel (1), for use as facade, wall and/or ceiling panel, wherein the panel comprises a high strength concrete part (10), said concrete part (10) having a front face and a rear face opposite said front face, defining a con- crete material thickness there between, and that side edges delimit the high strength concrete part, and an insulating part (20), where said insulating part (20) is partly embedded in the rear face of said high strength concrete part (10), where the material thickness between said front and rear faces is between 5 and 25 mm, and that a rigid profile (30, 32, 37) is embedded in or adjacent the side edges, and protruding from said side edges and the periphery of said concrete sandwich panel (1), where means(31,36) are provided in said profile (30, 32, 37) for fastening of the sandwich panel (1) to a construction, behind the sandwich panel (1).
