Description

Device for rapid evacuation of buildings

Object of the invention

The present invention relates to a device that has been specially designed for evacuation and / or escape of people, animals or objects from any level of any building, in the event that it does so advisable, such as a fire, an earthquake, attacks terrorists, or other risky situation.

The object of the invention is to achieve that the evacuation is extremely fast and simple, with a large eviction capacity

The invention thus falls within the scope of the passive security elements for buildings.

Background of the invention

In events such as those mentioned above, such like the fire of a building, obviously the speed of evacuation of the same is essential to reduce the number of victims

In small and low-rise buildings the evacuation before an accident can be carried out without means established for that purpose, but obviously as the volume of the building and especially as its height increases, evacuation is much more difficult, so that in towers high the use of elevators is absolutely insufficient to allow the evacuation of the people they occupy the building, and the stairs, besides being also in many cases  insufficient, do not allow a descent with the appropriate speed as to be able to reach the street before being caught by the calls.

Trying to minimize this problem are known outdoor stairs, safety, usable only in case of emergency, when placing users outside the building involve some protection against fire, but these External stairs are equally insufficient.

Facade elevators are also known, which just like the exterior stairs give a certain greater user security, but its benefits are not much greater than those of interior elevators.

Suspended platforms of rescue, whose capacity is much lower than in previous cases, since the rescue is done in a unitary way and requires a expert for its use.

Tubular ducts are also known,  usually network, which extend between a terrace or a opening of a building and the street, but so that these ramps are effective there must be one in each home or at least in each floor of the building, creating storage problems for the same, since if they are not preinstalled, only to at the expense of being thrown into the street from its location, in most of the time access to them and their installation makes its effectiveness is greatly diminished by the considerable loss of time.

Description of the invention

The evacuation device that the invention proposes to solve the problem fully satisfactorily previously exposed, allowing a mass escape of people in an extraordinarily short time and in full conditions security.

To do this and more specifically said device materializes on a helical ramp, intended for constitute a permanent complement to the building, ramp provided of lateral accesses numerically and positionally coinciding with The floors of the building.

The ramp is constituted by modules, preferably of height coinciding with the distance between plants, such as about three meters, gifted modules of coupling means, which can simply be tongue and groove, or be secured with fixing means Chemical or mechanical

In each module an axis or column is established central, preferably tubular, an outer tube of diameter appropriate, and between column and tube the ramp itself of helical slide, ramp with oval edges for better user body settlement.

In addition, the aforementioned modules are fixed to the structure of the building by rigid flanges that embrace the outer cylinder, for which purpose each module will be provided with outer tube level of perimeter projections intended for rest on the corresponding flanges, so that such flanges they have a double function, on the one hand prevent tilting side of the device and consequent fall of the same, and on the other contribute to the support of the weight of its structure, being Obviously, this fixing system can be replaced by any other appropriate.

The individual support system of each module also allows modules to be arranged without need to lean on each other, having planned the existence of an elastic joint that allows the closure of joints between modules.

According to another feature of the invention, it is provided that the inner column or tube, such as previously said tubular, house a pipe in its bosom to provide water to the ramp and / or extinguishing substances, facilitating in addition the sliding of the staff, cooling the structure and helping to turn off people or objects that join the ramp ablaze.

They can be wired in the same column as allow to provide the lighting set, preferably LEDs, powered by a stand-alone battery system to function as emergency light.

The lower end module, the one that remains level of the ground, it has a door with system anti-panic, with automatic opening from the inside.

It is also planned that the platform located under the lower module you can have free rotation, from the moment in which the exit door is opened, creating a rotating movement by the impulse of the people who they access the ramp, which in turn gives rise to a force centrifuge at the exit of it, and helps to evacuate more quickly to the staff, moving it away from the exit door.

The outer tube, open at its tip superior, and that optionally you can have some kind of rain cover, it will be shot naturally, favored by the evacuation holes it incorporates, which ensures a breathable atmosphere inside the device.

The device can be externally coupled to existing buildings or during construction, but may also be arranged in interior spaces such as stairs or elevator shafts, provided there is a possibility of space to that effect

Logically it must be made of a material With good fire retardant properties.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows, according to a representation schematic in perspective, one of the modules participating in the device for rapid evacuation of buildings that constitutes the object of the present invention.

Figure 2.- Shows, also on a schematic representation in perspective, the device in its set, ie stacking an indefinite number of modules, properly coupled to the outer side of a building, in this case and for reasons of simplification, of four plants.

Figure 3.- Shows, finally, a detail in coupling mode section between modules.

Preferred Embodiment of the Invention

In view of the figures outlined you can be observed as the evacuation device that is recommended is constituted by a plurality of modules (1), such as the represented in figure 1, each of which is structured by a central column (2), cylindrical, by way axis, located in correspondence with the imaginary axis of a hollow cylinder (3), of considerably larger diameter, constituting these elements, column and tube (2-3), an annular housing occupied by a ramp helical (4) of adequate slope to ensure the gravity displacement of people to slide by said ramp, without excessive acceleration occurring in such displacement.

Each module (1) can have any height that is considered convenient, but preferably its height or height axial will be coincident with that of each floor of the building (5) to whose security is intended, so that in the example of practical embodiment of figure 2, in which the building has with four floors, there will be four modules participating in the evacuation device

For stacking or coaxial mounting between modules, each of them is expected to incorporate in correspondence with the upper mouth of the tube (3) a small stepped recess (6), while at its edge or mouth lower (7) has a staggered in the opposite direction, so that the different modules are "pluggable" with each other by tongue and groove in disposition of perfect coaxiality.

Similar fixing means can be established between modules at the level of its central column (2).

Each module will be provided with an opening side (8), for access to the inside of the device, conveniently sized for this purpose, while the module lower end (1 ') has an outlet opening (9) that in the graphic representation of figure 2 appears open, but that except at the time of use of the device you will find closed by a door, single or double, with opening system anti-panic from within said device.

For the rest and as previously stated, the helical ramp (4) will present its oval edges for better body settlement of the user in his slip on the same, as shown in figure 1, fixing the device to the building (5) can be done with the collaboration of flanges that embrace the outer cylindrical tube (3), but still be any other type of fixing to the building wall is valid, enabling said fixation the independent lift of each one of the modules (1), without needing to rely on the module immediately lower, closing the joint between modules by an elastic seal (11) that can be fastened by screws (12), the central column (2) will be hollow to house in its interior water and electric pipes, with the benefits additional previously cited about it, and the device it can be mounted on a platform (10) that has free rotation, so that the weight of the users, when affecting a plane inclined and split into two vectors, generate through one of them, specifically of the horizontal vector, the auto-turn of said platform.

A device is thus achieved for evacuation of buildings that protects users from elements exteriors such as fire, rubble, etc., that can be installed in already constructed buildings as well as new constructions, which prevents the run over and / or stacking of people, which ensures a quick escape, much faster than the stairs of evacuation, which prevents the accumulation of fumes and gases in its interior, which allows rapid eviction of people disabled, even without help from other people, with just access the ramp, which avoids the risk to personnel of emergencies, which is applicable to buildings of any height, which no power supply required for correct operation, since it acts by simple gravity, and all with low production price, easy assembly and maintenance practically null.
