• sloping layer in the slab layers:

  • hydro
  • screed
  • thermal
  • sloped structural (reinforced concrete)
• how to increase loading capability of beam and block

  we need to thicken the slab by:

  • adding hollow bricks on top
  • or use higher system of blocks
• kiedy płyta pracuje jednokierunkowo 


  kiedy stosunek dłuższej krawędzi DO KTOTRZEJ jest większy od 2
• płyta pracuje wielukierunkowo gdy

  stosunek dluższej do krótszej jest mniejszy niż 2
• remaining part 1

  • 5-7 cm extend ring beam
• remaining part 2

  • less than 22 cm add brick and hollow brick
• ramaining part 3

  • more than 22cm

• efekt klawiszowania happens when load is not uniformly distributed
• czym zbroimy kleina

  • bednarką
• to strenghten steel beam

  use concrete around it
• risks when doing sloping layer in the reinforced concrete

  limitations when building in high relative humidity

  • damage of thermal layer
• przełazowa wysokość

  90-120 cm
• wet thermal isolation

  loses all its properties
• even in ventilated flat roof we use VAPOUR BARRIER


  over high moisture rooms

• strenghten wooden floor

  double beams

  increase cross-section

  strenghten wood with fibers
• imapct of quality of materials on health

  -better to use uniform materials -> no unpredictable chemical reactions
• jak uzyskać REI240?

  • Fire-resistant boards
  • sprayed fire retardants

  WOOD

  • impregnation (SODA ASH AND BORIC ACID)
  • sprayed paints
  • encasements (fireproof boards)
• increase fire resistance of steel

  -foam fire retardant

  cement plaster encasement

  fire resistant paints
• dylatacja

  • szczeliny dylatacyjne - masy ognioochronne
  • 25-50 m - 1 dilatation required - causaed by not uniform setteling of structure
• to increase loading capability of reinforced floor

  use more steel

  use THICKER rebars

  • or use beam and slab instead
