Abstract: A fixing cover (12) configured to cover an exposed portion of a fixing (10), the fixing cover (12) comprising a filler (20) and gripping means (40).

Abstract: A heat and fire protection system and methods of protecting structural elements and assemblies from heat and fire. When a steel structure is erected vertical columns of the structure typically comprise I-sections. In order to provide fire protection for the I-sections and so improve the resistance to fire of the steel structure a column protection system has been developed. The column protection system includes column protection elements which are placed around an I-section. The column protection elements are secured to the I-section. Horizontal beams can also be protected by the column protection system.

Abstract: A floor/wall structure, or panel, (10) supported on an I-beam (12) of a steel structure. The floor/wall structure (10) comprises an upper skin layer (14), a lower skin layer (16) and an intermediate layer (18) about 50 mm thick sandwiched between the upper and lower skin layers (4) and (16).

Abstract: A fixing cover (10) is hexagonal in shape so as to cover a bolt head or nut (as shown schematically in FIG. 4). The cover (10) has a body which can be made of metal, which would normally be steel or spring steel. In the three spaced side walls (12a, b, c) there are inwardly projecting indentations (14a, 14b, 14c).

Abstract: A composite comprises a structural component and a resin component, the structural component comprising structural fibres and a toughening additive comprising non-structural thermoplastic fibres and the resin component comprising a non-thermoplastic material. The structure component is a preform formed from the structural fibres and the thermoplastic fibres. The volume fraction of the structural fibres in the preform is at least 65%. The composite may be produced by forming a preform from structural fibres with non-structural thermoplastic fibres to provide a structural component. Liquid resin is then injected or infused into the structural component and cured.

Abstract: A bolt head cover (10) comprises an outer heat resistant portion (12) and an inner gripping portion (14). The bolt head cover (10) is arranged to be placed over the bolt head (16). The bolt head cover (10) is retained in position by means of the inner gripping portion (14) which grips the bolt head, with the gripping portion (14) being retained in the heat resistant portion (12) by means of flanges (18).
