FR2562130A1 - Modular protective shelter, principle of manufacture and method of construction - Google Patents

Abstract

Modular protective shelter characterised by a lightweight module consisting of a double permanent formwork element 1 and 2, which is strong, sealed and elastic, allowing in the cavity created between the two walls : the insertion in the workshop of a suitable reinforcement arrangement, solidly fixed to the walls; a pouring in situ of concrete having a consistency and composition adapted to the site. A removable cover 3, added straight after the concrete pouring, forms an air space 6 which, when ventilated 4, will ensure that the water is evacuated from the concrete, enabling the excavation digging to be immediately filled in.

Description

 DESCRIPTION "Nodular Protection Shelter" manufacturing principle and mounting method.

Goals
Produce an integral and complete component.

- Increased security by an adapted technology, made up of known elements
and unknown and whose originality rests more particularly on an ace
semblance or / and an integration of said elements allow to arrive at
the objective.

- Produce quickly in the workshop, therefore in an industrial manner, almost
entire finished product.

Transport and handling, facilitated by a weight of less than 5 T and a
footprint compatible with the road gauge not requiring a car
specialization.

- Very fast implementation on the field a day of 10 H. Discretion
assured.

- No rental of specific lifting equipment. A single mechanical shovel
immobilized one day on site ensures all the benefits
tions, possible earthworks, unloading, transport instead of
excavation, lifting of concrete containers If necessary, closing of
excavations.

 - Versatility of implementation.

 - Versatility of access systems.

- Possible combination between similar modules which can allow the
creation of a small collective.

Integral component
Protective shelter made with a prefabricated mono-block module
two polyester shells, one external (1) the other internal (2) between
which are installed in the workshop a reinforcement network adapted to
local mechanical constraints of the site. The whole thus constituted com
taking the lost formwork, the reinforcement and the whole team
classic interior elements necessary for the perfect functioning of
the shelter except for the few elements that are installed after the
implementation namely: filling of fluids (fuel, water
common foodstuffs and small utility items.
the rest is installed in the workshop, including bedding, special clothing,
measuring devices, radio, television, telephone, kitchen utensils,
storage batteries, compressed air, oxygen, auto gas
fense, first aid kit, tool kit, practical manuals for use of
food, medical and psychological facilities, recommendations,
equipment for the reception of small pets, stretcher, equipment
portable reels of portable electric lighting with energy reserves,
board games ... This list not closed to understand that
the product offered is an integral component which is delivered to the site
just like a gigantic habitable medical safety kit would be.

Security assured
The structure is composed in such a way as to be able to withstand different
your consequences of the effects of Nuclear Bacteriological and Chi weapons
mics, in particular resistance to the shock wave, by looking for the penny
modulus of the module, hence the use of optimal concrete thickness to avoid
the brittle effect due to the large thicknesses usually used.

Creation around the module when filling an environment
cushioning. Possible implementation, as appropriate, of additional screens
keep silent about ray penetration, increased protection of the structure by
the use of polyester by creating waterproof and airtight envelopes
implementation of a prefabricated reinforcement system and subsequent development
constraints, the volume of concrete being perfectly defined between 2 cof
lost frage, the use in some cases of special concretes albeit more
expensive can be considered.

Ex .: Ordinary concrete but dosed at 400 kg with plasticizer, barrite concrete with
suitable particle size, crushed iron ore concrete, ribblon concrete,
lead filings concrete or compound concrete with mixing in propor
defined definitions of the above aggregates.

The design of the double formwork allows, for example, to flow
in the lower part an ordinary concrete, in vertical wall a barrite concrete,
in the upper part a concrete of ribblons, this respecting flow times
age and dosage of plasticizer, in order to avoid segregation of the aggregates of a
concrete to another.

Increased security by the absence of hard points in the structure, the whole
partitions and interior equipment being suspended.

Quick manufacturing
- Thanks to an expandable modular mold, making the shells with
polyester, repetitive prefabricated reinforcement networks, the whole being
assembled in workshop.

Transport handling and fast implementation
- Thanks to the design of the cross section offering a habita ratio
optimum bility / resistance / cost, all while having a weight before pouring
around 5 T.

The duration of the site allows discretion, despite the importance of
intervention. The presence of heating cables attached to the fittings
allowing, among other things, an acceleration of setting of the concretes. A lid
ventilated at the end of pouring allows immediate backfilling of the excavation.

Versatility
The module is versatile by its location which can be aerial, semi
buried, buried or immersed. The complementary panoply to the module,
reinforcement systems, types of concrete and additional screens
can be reported.

Versatility of access systems
- Panels to solve all access problems from
outside, an existing room buried or not with possibility of exit from
rescue (see plates 9 - 12 - 13 - 14 - 15).

- The access frames are made of a double polyester formwork
into which a concrete which can be reinforced is poured. Access modules have
mechanical resistance and offer only limited protection
téè radiation, they are mechanically independent of the main module
pal, but are connected by suitable flexible joints, ensuring
continuity of watertightness.

Combinations of modules
- The modules which by design have an identical cross section and
variable length, can be stacked and / or juxtaposed to create
sets. Connections are possible to the right of the entrance hall, in
ceilings, floors and vertical walls.

- This patent concerns a type of product which, made with materials
known and experienced, polyester, concrete and steel, can enter, in
a near future, made with more efficient materials but still
expensive, we think particularly of the use of carbon fiber
combined in three-dimensional structure or honeycomb, to create a
structure whose performance will eliminate the use of concrete
and steel which will be replaced by a more resistant and more skin
flexible.

All the advantages highlighted by new elements or combinations
in this patent cannot be questioned by the
only because of a change of materials.
