DESCRIPTION:
BRIEF SUMMARY
The present invention relates to an earthquake-proof building.
Various earthquake-proof buildings are already known, particularly from documents: apparently of only relative effectiveness.
The present invention proposes to create an earthquake-proof building which also provides protection against other phenomena or catastrophes, particularly natural ones which are often connected with earth tremors such as fires or flooding.
The solution to this problem is an earthquake-proof building as defined in the first claim.
The other claims relate to characteristics and beneficial developments of the characteristics of the main claim.
The invention is represented by way of non-limiting example in the appended drawings in which:
FIG. 1 is a view in diagrammatic perspective of an earthquake-proof building in accordance with the invention,
FIG. 2 is an axial section of FIG. 1,
FIG. 3 is a partially cut-away view in perspective of the skeleton of the building of FIGS. 1 and 2,
FIG. 4 is a partially cut-away view in perspective of the building of FIGS. 1 and 2,
FIG. 5 represents, in an exploded view, the main elements which enter into the construction of the building of FIGS. 1 and 2,
FIGS. 6 and 7 are views in partial section on A--A and B--B of FIG. 2,
FIG. 8 is a partial plan view of FIG. 3,
FIG. 9 is a partial plan view of FIG. 4.
The building in accordance with the invention diagrammatically comprises a circular horizontal base structure 1, a vertical storey structure 2 forming, in the example represented, a single storey and a circular roof structure 3 of convex overall shape.
According to the example represented, the circular, horizontal base structure is composed of two identical dish elements 4 and 5 each produced with the aid of joined-together identical elements 4.sub.1, 5.sub.1 in the shape of sectors of a circle, with raised-up edge. These elements are juxtaposed along radii of this circular base structure, the centre of which is situated on the vertical axis X--X of the building.
The two dish elements 4 and 5 which are inverted with respect to one another bear on each other via their periphery with a joggle joint, the elements 4.sub.1, 5.sub.1 for this purpose including, on their raised-up edge, identical half-joggles 4.sub.2, 5.sub.2 (see FIG. 5).
Moreover, these juxtaposed elements 4.sub.1 and 5.sub.1 are joined together by joggles 4.sub.6, 5.sub.6 located along their planes of radial juxtaposition (see FIG. 3).
The centre end 4.sub.3, 5.sub.3 of the juxtaposed elements 4.sub.1, 5.sub.1 of the two inverted dish elements 4 and 5 are joined, by a tenon and mortice fitting, onto circular rings 4.sub.4, 5.sub.4, themselves each produced as two half-rings (see FIG. 5)
Pillars 4.sub.5 support the ring 5.sub.4, bearing on the lower ring 4.sub.4 (see FIG. 2).
The base structure thus produced constitutes a leaktight structure of which the resistance to earth tremors is obtained particularly by means of a cable 6 arranged under tension and horizontally encircling this base structure 1 at the height of the peripheral joining plane of the two dish elements 4 and 5.
The coaxial rings 4.sub.4, 5.sub.4 are themselves encircled by a tensioned cable.
The upper face of the second, inverted, dish element 5 constitutes the floor of the ground floor of the building and is extended, on the outside, by floor-terrace elements 7 supported by corbels 7.sub.1 and bounded by balustrade elements 8.
The vertical storey structure comprises pillars 9 and 10 and elements 11 forming a storey floor panel.
The pillars 9 and 10 bear via their lower ends at 9.sub.1 and 10.sub.1 (see FIG. 3), on the middle of elements 4.sub.1 of the first dish element 4 and pass through the second dish element 5 at 9.sub.2, 10.sub.2 at the height of half-joggles formed in the radially-pointing joint planes of the elements 5.sub.1. The elements 4.sub.1 and 5.sub.1 of the two dish elements 4, 5 are therefore angularly offset by an angle corresponding to half the subtended angle of each element.
These pillars 9 and 10 are preferably linked radially to one anothe
