Bridge beam I

Pre-stressed prefabricated elements in variable length sections: rectangular in the support zones and I-section in the span zones. Beams used in single- and multi-span bridge structures designed for traffic load class A according to PN-85/S-10030 and for special vehicle load class 150. Manufactured according to typical catalogue sizes or based on individual designs, intended for free-supported and tied spans with a span of 9 to 42 m. The beams are made of C50/60 grade concrete. Ropes of 15.5 mm diameter, variety I, are used as diameter splices. The top surface of the prefabricated is roughened with the phase II reinforcement released and prepared for splicing. The side and bottom surfaces of the element are smooth and do not require plastering. Holes can be drilled in the beams to accommodate installation passages and accessories can be sunk for the installation of safety and hygiene equipment, the so-called ‘Kobolds’.
