COFRASTRA 40 PDF

ArcelorMittal Construction offers several families of composite floors steel: Cofrastra and Cofraplus. Both are suitable for use in new and existing buildings. The steel floors are manufactured to the lengths specified on the order according to a slab layout plan and then delivered on pallets. The quick and easy implementation takes place in several expertly handled sequences by assembly teams. The steel floor is ready to use and can be walked on as soon as it is fixed. It constitutes a working platform providing perfect safety conditions.

That is why stoppers sheet distinguishes as it can be used in floor sheet of or flashing should be used on the intermediate props small thickness from 9 cm and, at the same time, at any sheet edge trims.

Metal sheets are equipped in a it has high adhesion strength which has an influence lengthwise snap fastener which makes mounting easier. Thanks to their Material light weight of 9. Cofrastra Safe load table. Reinforcement Approval and Standards At the composite stage, Cofrastra 40 because of its The design of a Cofrastra 40 composite reinforced specific characteristics, the mechanical constraints formed concrete slab, its dimensioning for the construction stage between the sheet and concrete resulting from the forces and composite stage and the design assumptions from the caused by surface friction and ribs is regarded point of view of fire resistance are exclusively based as a combined composite system which partially on the guidelines and methods stated in: or completely substitutes the bottom span reinforcement PN EN of a floor slab.

The total thickness of the floor resistance and the characteristic values for the design slab ranges from 9 cm to 20 cm.

The parameters required to check this aspect of load-bearing capacity have been ,37 0, 0,30 determined during laboratory strength tests carried out at the Building Research Institute, using methods compliant with PN-EN appendix B.

Additional service Punching Ready-made punching system Cofrastra 40 may be manufactured with pre-punched openings for connectors to join floor beams with the floor slab. All relevant calculations and production of pre-punched profiles are made on demand. Formwork of the floor slab edge A zinc-coated steel strip, bended at the right angle, Floor slab thickness Sheet edging thickness provides the formwork of the floor slab edge.
