摘要:
This invention relates to coverings for structural members to provide passive fire protection. An assembly comprises an elongate structural member; a pre-cast casting disposed around the structural member comprising an elongate heat insulating tube and a support tube. The elongate heat insulating tube being made of a heat insulating material providing passive fire protection, and the heat insulating tube having a continuous inner circumferential surface and a continuous outer circumferential surface. The support tube being encapsulated within the heat insulating tube between the inner circumferential surface and the outer circumferential surface. A stabilising element is arranged to maintain a gap between the inner circumferential surface of the heat insulating tube and an outer surface of the structural member.

The present invention relates to a method for producing a tower segment of a concrete tower of an wind energy installation, comprising the steps: providing a segment mold having at least an isolation for defining a mold of the tower segment that is to be produced and for filling with concrete; filling the segment mold with concrete in order to form the tower segment by the subsequent hardening of the concrete; measuring the tower segment thus hardened for creating a three-dimensional, virtual actual model of said tower segment; producing said three-dimensional actual model; comparing the three-dimensional actual model with a predefined mold, in particular a stored three-dimensional, virtual target model; and determining a deviation between both virtual models and changing the segment mold, in particular changing the at least one isolation when the deviation exceeds a first predefined threshold value.

The invention relates to a process for producing prefabricated compound tower-segment units (20) for a tower of a wind plant. A formwork (10) is supplied, and the formwork is filled with concrete. A low-viscosity material is applied, in the form of a compensation layer, to a flange of the prefabricated compound unit (20).

A method for storing nuclear fuel in a container (10) including a concrete body and a fuel receiver embedded in the concrete body, comprises the steps of: providing formwork (62) for the concrete body and supporting the fuel receiver within the formwork; placing the formwork in an immersed position in a pool (54) containing a body of water; placing concrete in the immersed formwork (62); and removing the formwork with the concrete body cast therein from the pool (52). A system for manufacturing a storage container (10) for use in the method comprises: a water pool (52) of a depth at least equal to the height of the storage container (10) to be manufactured; facilities for assembling concrete formwork (62) for the concrete body (12) of the storage container (10); facilities for moving the formwork and the fuel receiver to the water pool (52); facilities for placing concrete in the formwork (62) with the formwork immersed in water in the water pool (52); and facilities for removing the formwork (62) and the concrete body (12) therein from the water pool (52).
