DESCRIPTION:

BRIEF SUMMARY
PRIOR ART

This invention relates to a blast-proof building.
Buildings that are blast-proof to at least a certain extent against e.g. car-bombs, mortar and rocket attack, hereinafter termed "blast-proof buildings", are required in certain locations and/or for certain reasons, e.g. because of a terrorist threat. Such buildings must meet certain criteria, e.g. blast-proof protection, speed of erection. flexibility of size, demountability. One known building comprises a series of concrete cubes, suitably joined together. However, the maximum room size is constrained by the maximum size of cube possible. Also, construction and deconstruction can only be carried out cube by cube.


SUMMARY AND OBJECTS OF THE INVENTION

An object of the present invention is to obviate or mitigate these disadvantages, whilst still matching the required criteria.
According to one aspect of the present invention, there is provided a blast-proof building having one or more stories, or each storey comprising one or more rows of internal supports and having walls and a ceiling comprised of: and a ceiling portion, each corner of the free end of the ceiling portion being carried by a support; co-joining ceiling portion, the free corner of the ceiling portion being carried by a support and supports where there are a plurality of rows of supports;
Thus the walls and ceiling of the building of the present invention are modular, i.e. easily and quickly constructable and deconstructable. Each component is preferably integral and precast, and thus immediately ready for erection. The size and number of rows of the supports and the size and number of each type of component may be varied over wide limits to provide substantial flexibility in the size and shape of the building. Moreover, as the components form a shell, they provide complete flexibility for any desired or necessary internal spacing arrangements. The internal division of space may be made e.g. by stud walls.
The supports are preferably stanchions. The supports can form the `spines` of the building. Two rows of supports can be located symmetrically along the centre of the building to provide a frame for a corridor. Intermediate components extending from each row of such supports can provide room space on each side of the corridor.
Further rows of supports can be included to increase the size of the building. A multi-storey building may be formed by adding onto the ceiling of each storey the same components as described hereinbefore, with either supports of sufficient height or separate tiers of supports. If necessary or desired, further supports may be added to the building, e.g. to assist carrying the components or to assist division of any internal spacing requirement.
Access points, e.g. doors, can be included within the wall portions of either the intermediate components or the corner components. If necessary or desired, blastlocks can be included behind each access point.
Windows can also be included with the wall portions of either the intermediate components or the corner components. Preferably, the windows are replaceable by hardened blanks when not desired or necessary.
The inside of each portion of the ceiling, intermediate and corner components that form part of the outside of the building (some parts of which will not where there is a multi-storey building) may be steel-lined to prevent spalling of the inside of these outerwalls following a blast thereagainst, and thus to assist prevention of damage to the contents of the building.
Parts of some or all of the components may also have a double-skin construction comprising (steel) plates on both the outside and inside of such parts. The inside plate may be the spalling plate described above. Bolts or studs such as shear studs can connect the two plates. The outer plate(s) take at least some of the stress (upon impact of the building) normally taken by the inside plate(s). The double-skin construction is particularly suitable for use across the outside facing joints of the building, which may be its weakest points. Addition
