FR2698119A1 - Method of protecting buildings from hurricanes - involves stretching net over roof of building and fixing it to ground - Google Patents

Abstract

Before a hurricane arrives an air permeable material, such as a net (2) is stretched over the building (1) enclosing at least the roof (3). The net is stretched over the ridge (4) of the roof by slings (5). One end of the sling (5) is attached to the net (2) and the other end (9) is attached to fixed points (10) outside the building. The net can be made of metal, synthetic or natural fibres. USE/ADVANTAGE - To give hurricane protection to buildings. Reduces roof damage, prevents parts of roof flying off and causing other damage. Can be used on all types of buildings. Cheap, efficient protection.

Description

Anti-clonisue protection process for buildings and device For its implementation.

The invention relates to a new method of protecting buildings against cyclones, in particular tropical cyclones, and a device for implementing this method.

Tropical cyclones, also called typhoons and hurricanes, are made up of very small diameter atmospheric masses animated by a very high speed of rotation and a high speed of translation. These tropical cyclones, when they reach land, islands or coasts, have devastating effects, in particular on dwellings and, more generally, on buildings
Although the formation and displacement of these tropical cyclones are now observed in real time and with high precision, in particular thanks to meteorological satellites, the prevention of their effects is practically limited to people, who evacuate the area where the passage is planned. cyclone or protect themselves in shelters more or less buried.The effects of these cyclones on buildings, in particular the dwellings often built in light materials, are devastating and are undergone by the population without any means to oppose it.

The present invention therefore aims to overcome the devastating effects of tropical cyclones on buildings, in particular dwellings.

To this end, the method according to the invention is characterized in that one stretches over the building or villa, before the passage of the cyclone, an assembly made of an air permeable material, in particular a net, enclosing at least the roof of the building.

The invention is based on the fact that the most destructive phenomenon caused by the cyclone on buildings and villas is the tearing of the roof or roof which flies away and thus leaves the field open to the cyclone to completely destroy the 'building. To overcome this known phenomenon, the only solution proposed was to reinforce the quality of the installation of the cover and its accessories, such as ridgepoles and edges. This solution, the result of which is relative, only applies to new constructions, which are thus weighed down, expensive and burdened with very negative architectural charges. In addition, the impact on the roof of flying heavy objects, such as branches, sheets, parts of other roofs, coconuts, etc., is not eliminated.

On the other hand, with the method of the invention, the arrangement around the building of a stretched permeable sheet, preferably a net, surrounding at least the roof, makes it possible to eliminate or at least greatly reduce the direct effects and indirect effects of the cyclone. The cover remains placed on the building or villa even if some of its elements or accessories are damaged. The wind is thus prevented from freely attacking the roof structures, in particular the false ceiling, so that very effective protection is obtained, at a reasonable cost, and which can be implemented very quickly at approaching the cyclone. In addition, the protection according to the invention applies to both light constructions and heavier buildings, whether of old or modern construction, without harming the environment, in particular architectural aesthetics.

The invention also relates to a device for implementing this method.

The invention will be clearly understood on reading the following description made with reference to the appended drawing in which:
Figure 1 is a schematic elevational view of
front of a house equipped with a device according to a
exemplary embodiment of the invention,
Figure 2 is a plan view of the entire
figure 1,
Figure 3 is a schematic perspective view of a
fixing device outside the house and
Figure 4 is a schematic perspective view of a
attachment point on the house.

In accordance with the invention, before the announced arrival of a cyclone, a set of air-permeable material is stretched on the house 1, such as a tarpaulin pierced with holes, but preferably a net 2. The net 2 can be made with wire mesh, in particular steel wire, or synthetic son such as those known under the registered trademark "Nylon", or composite son or natural or synthetic ropes. The net 2 (or similar) is stretched so as to completely surround at least the roof 3 of the house 1.

The size of the mesh varies with the roofing material such as sheet metal, tile, shingles, etc.

According to the preferred embodiment shown in the drawing, the net 2 rests on the ridge line 4 of the roof 3 and is stretched by slings 5 fixed to points outside the house, for example concrete bases 6 and / or dots 7 at the bottom of the angles 8.

The fixing and tensioning of the slings 5 can be carried out in a conventional manner by means of quick shackles 9 of the boat type or of a mountaineer's hook each cooperating with a ring 10.

In the embodiment shown, the net 2 placed with its tension slings 5 affects, in plan view, a star or spider shape, stretched from the ridge line 4 of the house 1, the tips of the star being each fixed to a base 6 and / or to an angle 8.
