Beam & block floors
Bison Precast beam and block flooring system is quick, easy and economical to install. It offers numerous advantages, including improved acoustic performance and fire resistance. It is particularly suitable for intermediate flooring for houses where sound reduction, fire resistance and thermal mass are amongst its key benefits. The system consists of inverted pre-stressed T-beams with either lightweight aircrete (Thermalite) or dense and medium dense aggregate block infill.
Beam and block is a robust solution for cost-effective suspended floors. It is suitable for use on ground and upper floors in all kinds of construction, from residential to commercial buildings.
BEAM & BLOCK FLOORS - OVERVIEW
Inverted T-Beams
Bison Precast prestressed concrete beams exhibit an upward curve known as camber, which is a result of the compressive force near the bottom generated by the prestressing tendons. An allowance of span/300 should be taken into account in floor finishes or bearing levels.
Inverted T-Beams and Split Blocks
Split Blocks can be supplied in two sizes
1. To suit 150mm high beams
2. To suit 225mm high beams
