The present invention patent of "HELICAL RAMP LIFE-PRESERVER" refers to one or two helical ramps (Fig. 1 and 9), supported by the metallic structure, fixed on the building and supported soil by two pillars (Fig. 2 and 4), supported on blocks, that leans on stakes (if necessary), having as access, ramps (Fig. 1, 2, 3, 4) that links both catwalks (Fig 4-4), which make part of the BUILDING (Fig. 5, 6, 8, 9), that are fed by the cuts fire doors (Fig. 4-6), that allow the access to the catwalks or platforms of embarks (Fig. 4-4), protected by metal body protector (Fig. 3, 4) and its structure in concrete or metallic (Fig. 3, 4, 8, 9), defined by independent pillars, metallic semi-arches supports and flagstones into the body of the Building in subject. The helical ramps (Fig. 1, 5, 6, 8, 9), get down around the pillars, in straight and curved pieces (Fig. 1, 2, 3, 4, 5, 8, 9), allowing the agreement of the small spaces of the ramp, (Fig. 2, 3 and 4) which links the catwalks (Fig. 3, 4) to the main helical ramps (Fig. 3), allowing to watch another users' passages, seeking with this to avoid shocks or running over, in such a way to organize the going down. The water that runs through the tubes, irrigates the ramps (Fig. 6 items 1 and 2), then people who go down can and reach the pool (Fig. 5) placed in the quota determined by the building, being the water coming of the boxes (Fig. 6), placed on the top of the building. The pool should be placed on the point chosen to the final and exit of emergency of the Building eventually on disastrous. The ramps should have bars of protection like balustrade along its course, alike avoiding falls or sliding bodies outside. When there are not blind walls, there must be extended automatically a curtain of amianthus cement from the top to the bottom of the building, being viable its use and object of complement of this invention.
