RB BEAMS

RB-beams have a rectangular cross section and are designated RB w/h, where w is the width and h the height of the beam.  The beams are produced in standard width of 20, 24, 30 and 36  cm and heights varying from 40 to 90 cm in steps of 10 cm.

IB-BEAMS

IB-beams have a predominantly an I-shaped cross section with rectangular section at the ends. They are designated IB w/h, where w is the width and h the height of the beam.  The beams are produced in standard width of 30, 36 and 42 cm and heights varying from 70 to 160 cm in steps of 30 cm.

RB and IB-beams with alternative width and height can be produced within the limitations of size and weight.  The weight of the beams is based on a concrete density of 25 kN/m3.

Application

RB and IB-beams are usually used as roof and floor beams, supporting hollowcore slabs or TT-slabs, and are further used as bridge beams.  Roof beams can also support steel purlins and sheeting creating a lightweight roof.

ITB -BEAMS

ITB-beams have a shape like an inverted T and are designated ITB h/t, where h is the height of the beam and t is the thickness of the Hollowcore slab supported on the beam.  The beams are produced in standard width of 48 cm and depth below the slabs varying from 15 to 50 cm. However special beams can also be designed.

LB-BEAMS

LB-beams have a L-shaped cross section and are designated LB h/t, where h is the height of the beams and t is the thickness of the Hollowcore slab supported on the beam.  The beams are produced in standard width of 36 cm and depth below the slabs varying from 15 to 50 cm in steps of 10 cm.

 

ITB and L-beams with alternative width and height can be produced within the limitations of size and weight. The weight of the beams is based on a concrete density of 25 kN/m3.

Application

ITB and LB-beams are usually used as roof and floor beams supporting hollowcore slabs or TT-slab.

 

FB-BEAMS

FB-beams are flat beams with nibs and are designated FB W , where W is the thickness of the slab supported on the beam.  The beams are produced in standard width of 120 cm and depth below the slabs of 15 cm.

FB-beams with alternative width and height can be produced within the limitations of size and weight.  The weight of the beams is based on a concrete density of 25 kN/ m3.

Application

FB-beams are usually used as roof and floor beams supporting hollowcore slabs.  The depth of 15 cm below the slabs makes them suitable for structures where minimum obstacles for services are required.

COLUMNS

Production

Columns are produced in steel or plywood moulds.  Rectangular columns are cast horizontally, leaving the bottom and both sides fair-faced and the top surface smooth.  Circular columns are cast vertically with fair-faced surface.  The vertical casting limits the maximum height of circular columns to 8000mm.  Rectangular columns only have limitations that are due to size and weight.

Cast-in parts

As a standard, all columns are delivered with dowel holes or projecting bars at the top of the columns, lifting holes or anchors are bracing inserts.

Other project specific cast-in parts in rectangular columns can be openings, welding plates, inserts and bolts.  Cast-in parts are not allowed to project through the bottom and sides of the column.  Cast-in parts in circular columns should be discussed with our design office.

Corbels

Rectangular columns can be provided with corbels for support of structures like beams.  They can be provided at the top and on both sides whereas corbels in the bottom of the mould side should be avoided.  Corbels can only be provided at the top in circular columns.
