LEP 22.5 beams are reinforced concrete pre-beams of class C20/25 with welded wire shells with a diameter of Ø5 ÷ Ø7 from SPPB (periodic profile wire obtained by cold plastic deformation, which falls into resistance category 4) or PC52 for the soles (upper and lower);
wire with a diameter of Ø5 ÷ Ø6 from STNB or PC52 for the diagonals welded to the upper and lower soles 2 pieces and additionally, at the lower part, PC52 concrete steel with a diameter of 1Ø8÷2Ø14 or BST500S with a diameter of 1Ø8÷2Ø12.
All are mounted in ceramic cladding, ceramic elements of the FONDELE type arranged as dense ribs at an interaxle of 13 of 50 cm, 54 cm, 57 cm, depending on the type of ceramic block (TP16), concrete body or polystyrene block.
The beams are supported over a minimum length of 5 cm on the walls or beams of the structure, and there is also the possibility of supporting the LEP beam on wooden boxes if the following conditions are met:- the joint between the diagonals and the lower bar must be located in the support or at a distance from the internal end of the support of no more than 10 cm, or on the external support, according to the provisions of SR EN 15037-1: 2008 Annex D Chapter D.2.
Direct support arrangement (according to SR EN 15037-1: 2008)
- the anchoring length of the reinforcement at the bottom of the beam must be at least 15 cm in the horizontal direction (from the front of the support) and a 15 cm beak.
- The manufacturing lengths are between 1.60m and 7.70m, with a length variation with a manufacturing module of 20 cm section-beam-lep
- Section dimensions ( b x h ): 120mm x 40mm
- Manufacturing lengths: 1.60m ÷ 7.70m
- Manufacturing length module dimension: 20 cm
- LEP Beam Weight: 22.5 – 15.0kg/ml
Ceramic blocks for LEP floors
TP22 blocks for LEP floors are ceramic blocks with horizontal voids, with the approximate shape of a rectangular parallelepiped. In the LEP ceramic floor system, TP22 ceramic blocks are considered in the calculation as semi-resistant (according to the attached product sheet). The contribution of their upper sole to the active sections of the floor ribs is not considered in the calculation.
- Dimensions: 188 x 420 x 225 mm
- Interaxial distance between LEP beams: 51 cm
- Weight: 11.0 kg/pc
- Bending strength: min. 4 kN
- Thermal conductivity: 0.268 W/m K
- Apparent density in dry state: 600-700 kg/dm3
LEP floor systems with double or even triple beams can be used for local reinforcement in areas with increased loads (e.g. under partition walls or for bridging large installation gaps).
