Abstract

The invention relates to a life module for a flood zone that is available in two versions from a common base: in elevation above the ground or on one level. It comprises a hexagonal platform fixed on a triangular base formed by three piles (11) dark in the ground, secured by a concrete slab ensuring its anchoring. During the rising of the water, guided by three tubes, it slides vertically on its base thanks to inflatable air cushions (27) or by a rack device ensuring its elevation above the water. The constructive system of the invention allows an industrial prefabrication kit ready to mount and packing optimized for transport.

Description

Description

TECHNICAL AREA:

The floods are of natural origin, but today, experts have seen the increase in their frequency due to global warming. The impermeability of soils along rivers and seashores, a direct consequence of intensive urbanization also contributes to generating floods in previously spared areas. The global rise in sea level and the floods caused by these climate changes are inexorable. For these reasons, future constructions must adapt to these new configurations and make it possible to reclaim the coastal areas, while ensuring a minimum level of protection of property and people. We can distinguish 3 construction families to face the threat of flooding:

- Traditional construction fixed above water

- Traditional floating construction in a double hull

- Lightweight floating construction with or without anchoring

STATE OF THE ART:

PITERAC is a lightweight floating construction with anchoring, here are 3 existing processes which seem to summarize the state of the art in this family:

"Floating construction" according to patent No. WO 2007 030 013 (A2) -2007.03.15 It is a floating pontoon whose buoyancy is ensured by air trapped in boxes or by blocks of polystyrene. The tightness of the compartments between them does not prevent Titanic syndrome and the durability of the polystyrene blocks exposed to the debris carried by the flow is not guaranteed. The conditions of transport and launching of bulky and heavy elements are not specified, but require significant resources, The pontoon superstructure can generate instability due to the loads and the wind resistance which cannot be compensated by the ballast alone because it damages the buoyancy of the whole. As the anchorage of the building is not described, it could be moved by the flow away from its usual parking place.

"The floating house located inland" patent No. WO 9513212-1995.05.18 It is a house built on extendable jacks in height. The horizontal stability of the house cannot be ensured by the only jacks exposed to the force of the current especially for an elevation of 18 feet. Debris carried by the flow may disrupt the descent during the ebb and make the building unusable for the next flood. The occupants' survival conditions during a flood do not seem to have been taken into account, especially if the public networks are damaged by the flood.

"The arrangement of a mobile construction between 2 positions, one in support on the ground and the other floating" according to patent n ° WO 03 031 732 (A1) -2003.04.17 It is a question of a floating construction made around piles planted vertically in the ground, thanks to which the building slides during flooding. The position of the vertical guides, determined by the theoretical direction of water flow, does not guarantee the lateral stability of the building with cross currents formed by the eddies. The protection of the caissons on the underside is not provided and during reflux, the presence of debris may damage the building during the descent. The guidance system around the piles occupies an important place reducing the useful surface of the construction.

Characterizing elements of the invention:

We can see that the techniques known to date do not take, or do not take sufficiently into account the 10 criteria listed below, this in order to provide an adapted and global response to the risks generated by the floods:

1. Industrialization: the concept must allow prefabrication in series because it is not a question of building a single prototype but a duplicable building to reduce costs.

2. Exportability: construction must be able to be exported to all exposed countries and must be able to adapt to the specificity of each country

3. Transport: the building must be delivered in a packaging optimized in volume and weight to be easily transportable.

4. Simplicity: assembly must be manual and secure, to be carried out by unqualified and unequipped personnel.

5. The speed of implementation: the construction time must be optimized to allow rapid assembly in an emergency situation or during the preventive deployment phases.

6. Modularity: the concept must allow several modules to be assembled together to form living islands.

CH 713 657 A2

7. Durability: the construction must be partially or completely removable in order to be able to be moved, reassembled or repaired with interchangeable elements

8. Suitability for service: the operating constraints must be perfectly defined such as operating loads, permissible water height, wind and current resistance

9. Autonomy: survival conditions must be defined when public networks are damaged by the flood: alternative energy, water supply, electricity

10. The ecological factor: the use of components with a low carbon footprint, reusable, recyclable or locally made materials must be favored. The global carbon footprint must integrate all phases of manufacturing, from construction to deconstruction.

PITERAC seeks to meet each of these 10 criteria.

PRESENTATION OF THE INVENTION:

PITERAC is a life module for flood zones. PITERAC is available in 2 versions with a common base, the dimensions and the outer envelope of which are identical in the 2 versions according to the drawing below.

Diagram 9: Principle of assembly in island or in honeycomb The modules can be assembled by juxtaposition between them 2 by 2 up to 7 units together. This makes it possible to increase the surfaces of each living unit by a multiple of 65 m ² , but also to constitute small neighborhoods around a common courtyard according to the honeycomb layout (7 units), the central platform does not having a roof.

CH 713 657 A2

The only restriction is that the honeycomb layout is not compatible with the elevation system of the M2 module, which can only be guaranteed for the island layout limited to only 3 modules. Note that these provisions strengthen the anchoring of the modules by constituting a mesh of the foundation system which thus better withstands the force of the current during a flood or wind.

Conditions of use:

The points below are given as an indication to set the limits of use. The development phase will validate or adjust this data.

- The module can be used in hot or temperate countries, excluding cold countries: the foundation technique can be adapted to the geology of the soil, excluding hard soils: manual sinking in sandy, loamy, clay soils, peat or mechanical drilling in other soft ground where manual sinking is not possible

- If the water height fixed at 3m is exceeded, a safety height allows an additional clearance of 1.50m and beyond, an extrication device can be activated if necessary, allowing the release of the sound module anchorage.

- A sliding guying device can be adapted according to wind conditions.

- Gabions or a riprap cord can be placed around the perimeter of housing or neighborhood to limit the effects of the current and neutralize the cart debris

REALIZATION OF THE INVENTION:

Reminder: The present innovation is described with the support of the drawings and sketches in the appendix. These represent a preferred but non-limiting embodiment. The subsequent development phase will make it possible to confirm, complete or modify this data from a pre-project study.

1. Diagram 1: perspective of the recessed base 1 [0021] This is the base of the platform which is identical for the 2 modules M1 and M2. This consists of a triangular slab 13 of 2.80 m side in reinforced concrete embedded in the ground and fixed on 3 steel piles 11 anchored to a depth of 3.00 m for M1 or 4.50 m for M2. The 3 piles 11 are constituted by dark metal hollow tubes manually in the ground according to 3 techniques according to the nature of the latter: threshing by means of an self-locking clamp 17 adjustable during the descent of the tube 11; screwing using a claw wrench 18 for turning the tube 11 during its implementation; hydraulic jacking thanks to the holes located at the point 19 in the lower part of the pile which allow the filling of the hollow tube 11 and thus pushing back the materials by the gravitational push of water. The use of pressurized water improves sinking.

In the event of an obstacle blocking the advance of the tube, it is also possible to use all of these 3 sinking techniques simultaneously in combination.

After the earthwork of the base, to obtain a good verticality of the piles, a triangular steel template 12 to be sealed in the upper part of the concrete base 13 will be fixed on the formwork before the installation of the reinforcements and will ensure positioning and plumb with pre-dark tubes 11 to a depth of 1 m from the bottom of the excavation. After the concrete has dried, the 3 piles 11 previously coated with a PVC sheath over the thickness of the base to prevent it from setting during concreting can be driven in according to the 3 techniques mentioned above and fixed at the head on the integral template 12 of the concrete base 13. The 3 faces of the base 13 will be shuttered with a lost shuttering delivered with the package in order to constitute a monolithic block resistant to the current.

Connections to the public water supply, electricity, telephone 16 and wastewater, rainwater drainage 15 networks are made during earthwork so as to position the expectations at the center of the concrete base in a reservation box 14 allowing thus their connection during the subsequent phases.

CH 713 657 A2 Before the execution of the base 13, it is recommended to make a preliminary survey using a tube 11 to the depth indicated to check the nature of the soil. Being sandy, loamy, clayey or peaty soils; manual driving as indicated above seems possible. If the soil is too firm and does not allow this technique to be used, it is possible to use a mechanical drill that can be profitable if several foundations are made at the same time.

Entirely in commercial steel with a corrosion treatment, the constituent elements of the built-in base represent an estimated weight of 180kg or 5% of the package transported (excluding concrete manufactured on site). The adjustment variable for the built-in base is its concrete thickness estimated at 50 cm for a total weight of at least STonnes which can be adjusted according to the conditions specific to each country.

The triangular base on 3 piles is the concept that is best suited to ensure the stability and anchoring of the foundations, this regardless of the direction of the current.

2. Diagram 2: The mobile base 2 The mobile base 2 constitutes the support of the platform and contains the device which allows it to rise vertically. The basic principle is identical for the 2 modules but its design is different depending on the case. This consists of 3 hollow tubes 21 which slide vertically thanks to a lubricant inside the piles 11 on which are fixed in a precise assembly order the lower base 22, the upper base 25 secured to each other by the 3 tubes 21 and the 3 tubes 23 closing the hexagon as well as the central tube 24 ensuring the base of the mast. The whole thus forming a non-deformable structure of hexagonal shape with a side of 1.20 m and a radius for a height of 1.50 m to 2.50 m depending on the module. The admissible water height is 3 m in each case with a safety sheet of 1.50 m, but may allow an exceptional water level up to 4.50 m above the ground before being released from these guides. Composed of an aluminum structure, the components of the movable base 2 represent an estimated weight of 220kg or 6% of the package transported.

Diagram 2-1: plan view and elevation of the movable base M1 in normal situation With regard to the module M1, the mobile base 2, located under the floor 3 is 1.50 m high, which allows under the conditions normal service amplitude of 1.50m, and allows a height of elevation of 3 m above the ground. The 6 floats 27 made up of a flexible and resistant membrane are housed in each of the prisms of the hexagon. They are independent and folded up in normal situation according to 27a. When the water rises, they inflate electrically with air in accordance with 27b with an automatic or manual triggering device in the event of failure and thus allow the platform to be raised. The volume of the 6 inflators represents 5.5 m ³ and can therefore ensure the elevation of the platform whose loaded weight of the mobile part is estimated at 5T with a satisfactory safety margin. A removable peripheral protection 26 fixed on the interior uprights of the 6 faces of the hexagon will protect the floats against the risk of collisions caused by debris carried by the flood.

Diagram 2-2: plan view and elevation of the M2 mobile base in normal situation With regard to the M2 module, the mobile base 2, located above the floor 3 is 2.50 m high which allows an amplitude of service of 3 m and therefore authorizes an elevation height of 3 m above the ground. A rack and pinion device 28 fixed on 2 vertical profiles arranged on either side of the central tube 24 and bearing on the fixed base 13 allows the platform to be raised by means of a manual or electric winch 29 with or without automatic triggering.

Diagram 2-3: elevation of the movable base M2 in a flooding situation [0032] During a flood, 3 cables 20b attached to each of the angles of the movable base 2 allows the mid-height positioning of the stiffening triangle 20a which ensures the lateral bracing of the tubes 21 and the correct telescoping of the sleeves 15 for the flow of the wastewater. The water, electric and multimedia supply lines deployed in the form of a lyre are kept in tension by a cable device with spring.

A variant is possible for the system allowing the elevation of the platform M1: it is a question of replacing the inflatable air cushions by blocks of expanded polystyrene. This solution offers the advantage of eliminating electric or manual inflation but has a significant drawback linked to the insufficient durability of the material to UV rays and to environmental damage (rodents, -). In addition, this variant degrades the ecological criterion and increases the volume transported.

3. Diagram 3: vertical section on the floor of the modules M1 and M2 The floor 3 is identical for the 2 modules but its support is different depending on the case. Its structure is made up of wooden joists 31 and 34 type bastings of 6.5 * 17 cm radiating around the core 24 and connected to each other by aluminum junction elements. The assembly serves as a support for the floor 35 composed of 15 mm thick pre-cut plywood sheets implemented after the interposition of a polyethylene film on the beams 31 and 34, ensuring a sealing barrier.

CH 713 657 A2 It is delivered in a kit with pre-cut elements and will be assembled on site in a precise order indicated below. In the central part, 2 removable hatches 38 constitute technical access to the floats or to the introductions. To allow the juxtaposition of an island or honeycomb platform, 2 assembly ball joints 63 can be fixed to the edge profile 32 thanks to pre-drilled holes on each side of the hexagon.

The floor 3 measures 5 m in radius and on the 6 sides, it is the heaviest part of PITERAC because it represents a weight of about 1600 kg or 45% of the package. The essentially wooden floor is a renewable ecological material that can even be produced locally, thereby significantly reducing the weight and volume of the package.

As for the module M1 as indicated at the bottom of the diagram, the floor is built in elevation at 1.50 m above the ground. It is supported by 6 triangular trusses 31 reinforced by struts. The trusses 31, arranged in a radius thanks to the base fixed to the head of the tube 24, are fixed to the upper base 25 and to the inclined shoes 33 located at each angle of the lower base 22. A peripheral aluminum profile 32 located in shore connects the beams 31 and closes the 6 faces of the hexagon. The secondary beams 34 can then be fixed to the edge profile 32 by means of welded connectors and the upper base 25 by means of stirrups 37 provided for this purpose.

Regarding the M2 module as shown at the top of the diagram, the floor is built on the ground thanks to the 6 main radiating beams 31, bearing on the straight shoes 33 fixed on the lower base 22 and connected at the ends by the edge profile 32. The 6 shrouds 36 which connect the ends of the beams 31 to each of the angles of the upper base 25 support the assembly. These are adjustable in tension and compression to ensure the rigidity of the platform. As previously for the module M1, the secondary beams 34 can then be fixed to the edge beam 32 by means of welded connectors and to the lower base 22 by means of shoes 33 arranged outside of it.

In both cases, the floor 35 composed of pre-cut plywood sheets 15 mm thick and arranged in a precise order can then be implemented after the interposition of a polyethylene film on the beams 31 and 34, ensuring a sealing barrier.

A variant is possible to improve both the insulation of the floor and facilitate the elevation of the platform during flooding for the modules M1 and M2. This involves attaching expanded polystyrene panels between beams 31 and 34 under the plywood floor: for example, 5 cm thick under the floor represents an additional buoyancy capacity greater than 2 m ³ , i.e. 2000 kg of overload. This solution can supplement or replace the lifting device 27 or 28-29 previously described but has a significant drawback linked to the insufficient durability of the material to UV rays and to environmental damage (rodents, -). In addition, this variant degrades the ecological criterion and increases the volume transported.

4. Diagram 4: vertical section before and after mounting the roof The roof 4 is identical for the 2 modules but is mounted differently depending on the case. For the understanding of the drawing, the left part represents the roof during assembly and the right part after its elevation. It is a radiant aluminum structure around the mast 41, composed of 6 inclined beams 45, reinforced by struts supporting the intermediate and shore purlins 46. A hexagonal tarpaulin made of a waterproofed canvas 47 made of light, waterproof, UV and tensile material covers the structure in a single part. It has a hole in its center for the passage of mast 41 which also serves as a ventilation and technical access port. The tarpaulin is supported by a tail system identical to the sails of boats, housed beforehand in planned slides and is then attached by means of fixing strips arranged on the underside through beams 46. It will be held on each side by eyelets to be fixed on the shore plate 56 laid during the next step. It is installed after the 6 photovoltaic panels 48 installed in an aluminum structure corset previously assembled in corole at the top of the mast 41 after its elevation.

Regarding the module M1 shown at the bottom of the drawing, the roof 4 mounts to the ground as indicated above on the floor of the platform after having erected the mast 41 in its sheath 24. The entire structure carrier of the roof is fixed on a tube supporting the lookout 42 sliding around the mast 41, thus constituting a secure hexagonal decking coated with a grating. Once assembled, the roof 4 is raised vertically thanks to the cable winding system associated with the ratchet winch 43 fixed on the lookout 42 and connected to a double pulley 44 fixed at the head of the central mast 41 to a height of 2 m above ground.

Regarding the M2 module shown at the top of the drawing, the beams 45 are suspended at the head of the mast 41, the struts being articulated on the collar 49. In the lower part, they are supported temporarily on the shrouds 36, which allows the mounting of the secondary beams 46 and of the tarpaulin from the floor or from the top of the movable base 25. The whole of the roof is then deployed like an umbrella thanks to the collar 49 which slides vertically from top to bottom around the mast. This is actuated by a cable winding system associated with the ratchet winch 43 fixed on the mast base 24 connected to the collar 49 thus allowing the assembly to be raised from the upper part of the mobile base 25. This ci coated with a duckboard constitutes a safety deck located 2 m above the floor replacing lookout 42 of module M1.

CH 713 657 A2 The hexagonal hexagonal roof is erected at a height above the ground of 6.20 m for the module M1 or 4.70 m for the module M2. It weighs around 640kg or 18% of the package transported. This assembly or disassembly system allows you to work safely at height without the use of scaffolding or lifting equipment. This explains why the roof 4 is erected before the facades 5.

5. Diagram 5: elevation of the facades The facades are identical and are mounted in the same way for each of the modules. Their walls are made of honeycomb panels 53 made of light waterproof materials, resistant to the effects of wind and UV, which slip into the wings of the aluminum H posts located in the angles 51 or intermediate 52 these being fixed at the bottom in the edge profile 32 of the floor. When the facades 5 are assembled, the roof 4 which was erected according to the previous step to a slightly higher height can be lowered thanks to the winch 43 and can come to cap the assembly, each beam 45 coming to fit into the post d 'corresponding angle 51, ditto for the secondary beams 46 in the intermediate posts 52, A profile 56 placed at the head of the walls forming gutter-sandpit surrounds the upper panels and ensures the connection with the cover 47 which can be tensioned on the profile 56 thanks to a tensioner arranged on the bank passed through the provided eyelets. The installation of the 6 tie rods 57 connecting each angle of the roof to the lookout 42 for the module M1 or to the upper part of the base 25 for the module M2 completes the stiffening of the outer envelope of the platform. The panels 53 are superimposed thanks to a lip rejingot which seals the horizontal joint, the vertical junction of the panel with the posts being ensured by a compressed watertight seal located at the bottom of the wing of the H. The first row of panels is fitted with a bib at the bottom. The panels are interchangeable and all have the same dimension of approximately 1.62 * 0.52 m corresponding to an interval between posts for 4 rows in height. The height of the facade wedged on 2.10 m allows an interior useful height of 2m. Each facade having an angle post 51 at each angle and 2 intermediate posts also distributed is provided in the central part with a window 55 or a door 54 for the entry or the communication between module of dimension multiple to that of panels 53. The French doors are fitted with simple glass or plexiglass glazing. The weight of the set is estimated at 720kg or 21% of the package transported.

6. Diagram 6: plan view and partial section on the equipment For the understanding of the drawing, the facade is partly erased on the elevation and the roof on the plan view; the left side represents the M1 module and the right side the M2 module.

The following common equipment is provided for the 2 modules:

The decking of the lookout 42 (Ml) or the upper base 25 (M2) supports 2 cylindrical polyethylene tanks 65, of 2001 each, placed diametrically on each side of the mast 41 to ensure balanced storage of water from rain. These are fed by the funnel formed by the solar panels 48 via an activated carbon filtration device 66 responsible for the distribution between the barrels and provided with an overflow device towards the public network passing through the interior of the mast 24. This 1.20 m side and radius deck also supports batteries 67 supplied with electricity by the photovoltaic panels 48 which provide the emergency lighting and the main functionalities of the platform in the event of a network failure. A retractable ladder 68 allows access to the decking consisting of a grating on the ground and secured on the shore by a railing with posts and chain 69. Finally the structure of the decking 42 (M1) or 25 (M2) serves as a point of attaches 6 tie rods 57 with the facades.

For the assembly of modules M1 or M2, ball joints 63 fixed with pre-drilled holes on the edge profiles 32 (2 per side) allow the mooring of the platforms with sufficient play to absorb the movements caused by rising waters.

The following specific equipment is provided for each of the modules:

Access to the platform is provided either by an access staircase 61 composed of wooden steps fixed on 2 metal stringers provided with retractable railings, or by an inclined ramp 62 for the M2 module, the whole articulated on the edge of the platform and hoisted like a drawbridge during the flood.

With regard to the M2 module, partitioning partitions 64 made of light honeycomb panels are arranged in line with each shroud 36, dividing the space into 6 sectors connected by a free passage around the core.

This equipment represents an empty weight estimated at 140kgs or 4% of the package transported.

Regarding the introduction of fluids on the mobile platform, they are thus declined from the expectations on the ground arranged in the reservation box 14 according to diagram 1:

- The wastewater is removed inside the mast 24 before being connected to the telescoping sleeve 15 located under the floor 3 according to diagram 2-3.

- The connection of drinking water, electricity, multimedia is made to the right of the mast 24 under the floor 3 with a flexible lyre-shaped hose stretched by a cable and connected to the expectations 16 according to diagram 2-3.

These provisions allow an amplitude of 3m; beyond this, an automatic shutdown system neutralizes the connections and the above-mentioned emergency equipment replaces the public networks.

CH 713 657 A2 Optional sanitary accessories not described and not shown in the diagrams can be fitted around the central core which concentrates all arrivals, this for better layout and balancing of the platform. PVC or stainless steel sanitary ware should preferably be used for their low weight, in particular: kitchen sink, shower tray, WC, sink, -.

In general, accessories and furniture should favor lightness and insensitivity to humidity.
