LEP 14.5, LEP 16.5 beams are reinforced concrete pre-beams of class C20/25 with welded wire shells with diameters 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 diameters of Ø5 ÷ Ø6 from STNB or PC52 for the diagonals welded to the upper and lower soles, 2 pieces and additionally, at the bottom, PC52 concrete steel with diameters of 1Ø8÷2Ø14 or BST500S with diameters of 1Ø8÷2Ø12.All are mounted in ceramic cladding, ceramic elements of the FONDELE type arranged as dense ribs at 13-axis spacing 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 conditions are met:- the joint between the diagonals and the lower bar must be 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 anchorage 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 the 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: 14.5 – 10.0kg/ml
- LEP Beam Weight: 16.5 – 12.7kg/ml
Ceramic blocks for LEP floors
TP16 blocks for LEP floors are ceramic blocks with horizontal voids, with the approximate shape of a rectangular parallelepiped. In the LEP ceramic floor system, TP16 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 450 x 160 mm
- Interaxial distance between LEP beams: 54 cm
- Weight: 8.5 kg/pc
- Bending strength: min. 3 kN
- Thermal conductivity: 0.214 W/m K
- Apparent density in dry state: 600-700 kg/dm3
LEP concrete slab block
The LEP concrete slab block has horizontal voids and the approximate shape of a rectangular parallelepiped.
- Dimensions 200 x 480 x 160 mm
- Interaxial distance between LEP beams 57 cm
- Weight 12.48 kg/pc
- Compressive strength 14.54 N/mm2
- Thermal resistance 0.191 m2K/W
Polystyrene blocks for LEP floors
Polystyrene blocks for LEP floors are made of ARCO EPS 70 fireproof expanded polystyrene, which is lightweight, easy to process and handle; it does not have any voids.
- Dimensions: 1200 x 420 x 160 mm
- Interaxle distance between LEP beams: 50 cm
- Weight 1.16: kg/pc
- Tensile strength: ≥100 kN/m2
- Thermal conductivity: 0.038 W/m K
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).
