The Anti-Seismic Standards (DTU PS-MI89) require a certain number of preventive construction provisions, in particular:
- Foundations that are tied both together and to the superstructure via continuous reinforcements
- Longitudinal and transverse bracing in order to stiffen the building in both directions
- Ties between walls and ceilings in order to withstand the different types of oscillation (longitudinal and transverse), torsion and vertical vibration
- Ties between the various components of the construction
- Framing around bays and openings
- Attached staircases
- Transfer of floor loads to walls and bracing.
The design of the JK STRUCTURE construction procedure meets these construction standards perfectly and the use of ‘light’ concrete (300-900 kg/m3) moreover alleviates the associated constraints.
Robust roof structures that are integrated into the structure of the house are more resistant than traditional timber frames and obviously also much more resistant than metal sheet panels.
The above-mentioned tests carried out by CEBTP-GINGER demonstrate that the noise reduction from a wall of only 10 cm is 41 dB, which is equivalent to the reduction achieved by a 20 cm brick wall.
The above-mentioned thermal tests carried out by CEBTP-GINGER demonstrate that the thermal insulation coefficient of a JK STRUCTURE wall assembled with JK STIFFENERS and injected with alleviated concrete in accordance with JK STRUCTURE SPECIFICATIONS is λ=0.24, which means it has approximately five times the insulation capacity of a brick wall. If one considers that the density of a brick is at least four times higher, then it follows that the brick mass would need to be (5 x 4 = ) 20 times higher to achieve the same result as the JK STRUCTURE WALL.
Thanks to the low loads engendered by the JK Construction process, the design of JK STRUCTURE walls allows, with no significant extra structural reinforcement than what is already intrinsic to the JK STRUCTURE specifications, the construction of individual houses and R+3/R+4 type apartment blocks. The design of the floors allows floor spans of 4.50 metres without any specific additional reinforcement. This procedure also makes it easy to incorporate decorative and architectural features.
The above-mentioned tests carried out by EFECTIS demonstrate a fire resistance of 110 minutes for the walls and 90 minutes for the floors. The full results are available on request.
Waterproof: Average permeability to steam 136g Im2/24 hours. The walls breathe efficiently and housing is therefore healthy and damp-free.
As with any reinforced concrete construction, the durability of JK STRUCTURE constructions depends entirely on the quality of the cement used, the other components of the alleviated concrete and JK STRUCTURE wall being completely neutral (notably without risk of alkali-aggregate reaction).
No vulnerability to chemical reaction.
The reliability of the JK Structure products is not subject to, but what other specific advantages of this product mean that you will never again be able to do without?
- Little or no skilled labour.
- No expensive heavy equipment on your construction sites.
- Excellent thermal and acoustic performance.
- Excellent profitability margin.
- Its technical characteristics make it suitable for use in seismic and hurricane risk areas.
- Thanks to an intrinsic eco-responsible approach you safeguard the occupational health of workers on construction sites.
