Application

Suitable for projects that require a low-profile or lightweight concrete floating floor. Also suitable for areas with high live loads.

Description

Stravifloor Deck is a low-profile floating floor system using a proprietary dovetailed metal deck for thin concrete pours. The system’s high bending stiffness allows for concrete toppings as thin as 50 mm.


Stravifloor Deck provides a high-performance floating floor system for excellent structure-borne and airborne noise isolation while minimizing any impact on the available floor-ceiling height.


Features and benefits:

  • Stravifloor Deck standard solutions are available with resilient pads in four standard grades: Pad-L (low stiffness), Pad-M (medium stiffness), Pad-H (high stiffness) and Pad-X (extra high stiffness).
  • The system can be changed to meet project specifications in terms of natural frequency and damping requirements, Ln,w or Rw using non-standard bearings.
  • The standard range of resilient pads is available to provide load-bearing capacities from 0.1 to 3 MPa per pad.
  • Uses elastomeric isolators with low stiffness/ high resilience allowing natural frequencies as low as 6 Hz, or springs allowing natural frequencies as low as 2.5 Hz.
  • Steel parts are galvanized.
  • The system allows high bending stiffness specifically for both restricted build-up height and limited extra weight applications (low permanent weight with floor system from only 86 mm total thickness: 36 mm resilient support + 50 mm steel reinforcement sheet with concrete or screed floor).
  • The system is compatible with high permissible loads.
  • High performance floating floor system with large support spans (up to 1200 mm).
  • Quick to install resulting in a cost effective solution.
  • Allows services to be installed within the air void.
  • Easy to incorporate underfloor heating or cooling systems.
  • Isolation pads, used as discrete resilient support of the system, are mold and water resistant.
  • Uses moisture resistant formwork, free of autochthonous parasites or other harmful organisms and is lightweight and easy to handle.

Specification data - Composite steel and concrete deck systems

Framing members

Galvanized carbon steel isolated channels.

Manufacturer guidance

Note: the channel spacing - which can be between 400 to 1200 mm - need to be determined by the CDM Stravitec engineering team according the (concrete or screed) floating floor thickness and the load cases in operation phase.

Steel channel standard length: 2 m.

Steel channel standard thickness: 0.75 mm.

Permanent formwork

-

Steel profiled sheet for composite floor slabs and beams

Steel profiled sheet.

Manufacturer guidance

Dovetailed sheeting

Steel thickness: 0.5 mm.

Nominal width: 630 mm.

Effective width: 580 mm.

Standard length: 2200 mm. (Other lengths available upon request.)

Effective length: 2100 mm.

Dimensional tolerances: Length: 1-4 mm; width: 1-3 mm.

Moment of Inertia: Ix = 3.6 cm⁴/m.

Moment of resistance: Wx = 3.0 cm³/m.

Fixings for permanent formwork

-

End support fixings

Up to 20 mm autodrill screws.

Side support fixings

Up to 20 mm autodrill screws.

Ancillary accessories to permanent formwork

Metal L-profile and possible restraint straps as formwork for edges.

In situ concrete topping

C20/25 fine grade aggregate concrete.

CA25F4 free flowing, self levelling, liquid screed.

Manufacturer guidance

Minimum ‘fine grade’ concrete thickness: 16 mm profile height + 34 mm = 50 mm.

Reinforcement

-

Type of reinforcement

Steel mesh.

Manufacturer guidance

The steel mesh necessary to cope with the loads in the finished floor needs to be calculated for the load cases in operation phase (service phase). This needs to be done by a structural engineer (upon request, CDM Stravitec can provide recommendations).

System accessories

Metal L-profile and possible restraint straps for edge formwork, perimeter strips, autodrill screws, etc.

Standards

Rw measured in accordance with ISO 10140-2:2010 (with additional vibration analyses) and single figure ratings determined in accordance with ISO 717-1:2013 by the lab responsible for the measurements. Ln,w and ∆Lw measured in accordance with ISO 10140-3:2010/A1:2015 and single figure ratings determined in accordance with EN ISO 717-2:2013.
