Floors / Ceilings - VELOX

  • VELOX ribbed monolithic ceiling
    VELOX monolithic ceilings are key elements of ribs formed using PERI slab elements.
    • Ceiling element's basic dimensions: length l = 2000 mm, width 500 mm = b1, b2 = 380 mm
    • Module dimensions: length 1830, 1660, 1500, 1330, 1000, 660, 500, 330 mm, width 330 mm = b1, b2 = 180 mm
    • Choice of its application depends on the range, payload, ceiling object quality concrete and reinforcement content
    • Reinforcement ribs are ceiling VELOX spatial steel beams, respectively.
    • Coupled Reinforcement every two meters, i.e. at the connection of ceiling elements for greater spatial bracing object transverse ribs
    • Deployment supports - under the front contact elements
    Ceilings created with monolithic reinforced concrete ceiling cassette (non-standard elements)
    • Used for ceilings with 'special use' (concert halls, theaters, etc.)
    • Transverse ribs are positioned in axial distances of 500, 660, 1000, 1330, 1500, 1660, 1830, 2000 mm
    • Choice of application depends on the range, payload ceiling of the building, the quality of the concrete and reinforcement content
    • Reinforcing ribs bonded reinforcement supports deployment by the length of the ceiling element

  • VELOX monolithic ceiling slabs
    If you decide to build a ceiling using VELOX WSL boards as permanent formwork for a reinforced concrete monolithic slab ceiling, you might be interested in the following information:
    • They can be used only with reinforced concrete floor slab reinforcement according to the static calculation.
    • The axial distance support formwork panels with a thickness of concrete slabs up to 200 mm, 660 mm.
    • Compared ceilings made of prefabricated box-shaped ceiling conserves material, but uses more concrete.
    • The advantage is a good thermal and acoustic insulation ceiling.
    • Typical features and elements with a height of 260 mm are made to order.
  • VELOX WSL boards
    Cement bonded woodchip board, reinforced longitudinally by wooden battens. Used for shuttering of monolithic ceilings.

  • VELOX trigon - Vertical reinforcement
    • Used to ensure the verticalness of walls
    • They are placed, depending on requirements, inside the formwork ( normally every 2 m, or either side of openings)
    • They are manufactured from high quality steel 10505 and are available in lengths of 2,800, 3,000, 3,200 and 4,000 mm
  • VELOX trigons - Horizontal reinforcement
    • Used with ceiling modules to reinforce rib ceilings (placed between each ceiling module spanning from supporting wall to wall)
    • Used for reinforcement above openings (doors/windows)
    • Door/windows overlapping the clear span by 150mm either side)
    • Available sizes are specified below
    • Made of Steel group R10 505
