Prestressing steel - Import export

This type of joint was specifically designed for highway use within structures creating horizontal movements up to 15 mm and vertical movements up to 5 mm. Due to its characteristics, it can be fitted on any type of structure, whether it is made of reinforced concrete, prestressed concrete or steel. It consists of: • a Hypalon gutter, ending at its extremes with a mesh securing it to the slab; • a neoprene ribbed bulb, of suitable section, resting onto its upper wings on the edges of the slab heads, recessed within the gap. The Hypalon gutter ensures watertightness of the deck and drainage of waters outside of the road bed. It is a seamless type of gutter and it covers the entire road bed with the right slope and it is fixed to the slab by means of a mesh with epoxy adhesive and primer.

 The function of the neoprene bulb is to support the overhanging pavement. JOINT TYPE HEIGHT H (mm) WIDTH *X (mm) GAP *Y (mm) Bulbo piccolo 43 45 Max 20 Bulbo medio 77 80 Max 40 Bulbo grande 90
