These beams span between the columns and are placed at regular intervals (generally 7-8m bays) along the length of a stand. Seating units are then placed between the raker beams, to provide the seating area, on typical stadium designs. They are generally long span beams (depending on the size and scale of the stadium) and have been cast up to 20 m. These beams come from individually fabricated moulds and have a fair face finish. They are cast with dowel tubes to connect with the seating units, which span onto them.
Raker beams are cast in concast’s adaptable moulds, and vary in size and shape, depending on the requirements of an individual job and the requests of the client.
Seating units are used to span between raker beams in sports and leisure stadia, and form the exposed surface which the seats are bolted onto. Concast has worked on many of the well known stadia in Ireland, such as Croke park and the O2 arena etc. In Croke park, Concast installed over 3,600 seating units, as well as raker beams, slabs and wall panels etc.
Concast have a number of existing moulds for seating units, but can also fabricate new moulds, depending on the requirements of the client.
The end section and length of these seating units can be varied, in accordance with the span and angle of the bays between raker beams, to form the curved section at the corners of the stadia.
Seating units can be easily installed on site, and when the joints between units have been sealed, form an effective barrier against external elements. Precast seating units can also be easily installed in steel structures.
