POLIDIL - General
Polidil is the system expansion joints developed and designed for bridges, roads, ramps, with the participation of professional institutions IGH Zagreb in quality control in the stages of development and testing of finished products and providing quality certificates or technical approval for production.
Basic characteristics of the product:
- elements are of length 1100 mm
- mounting with screws only
- dimension thickness (44mm, 55mm, 60mm, 84mm), can be better tailored to the facility
- easier installation
- easier maintenance (if necessary replace only one part)
- waterproof guaranteed
- all valves within the device (steel reinforcement, screws)
- meet all the requirements of the project, which must withstand the traffic loads
- serving all movements resulting from:
- expansion and contraction due to temperature oscillation
- rotation caused by the load
- braking forces transmitted to the structure
- elastic shortening due to over-stretched
POLIDIL system expansion device ensures driveability and water resistance movement joints in the range of 50-165 mm, so we developed four types of devices:
- POLIDIL 50 (total shift 51 mm)
- POLIDIL 75 (total shift 75 mm)
- POLIDIL 100 (total shift 101 mm)
- POLIDIL 165 (total shift 165 mm)
Selection of devices depends on the total expected shifts, due to temperature changes, rotation, remove the reservoir, brake, etc. Compared to other systems, expansion joints POLIDIL system has significantly improved the performance of the transition from the traffic on the pedestrian part of the roadway. Specifically, the exact topographic survey at a factory making parts that exactly match the geometry of the bridge (profile and slope). Thus avoided plain cover plates on most slanted bridge.
Material
POLIDIL is a modern system designed elastomeric expansion joints designed for bridges, ramps and roads. Designed for long life under heavy traffic. Latest improvement over the expansion joints of this generic type is installation of an aluminum plate on the running of the device that is resistant to wear, which she greatly extended service life.
Slip resistance
Slip resistance is obtained by amended in order corrugated aluminum plate high strength. This reduced large areas of exposed rubber traffic. Drainage grooves on the sides expansion joints allow the rapid swelling of the surface water.
Armour for a long duration
The rounded edges of the aluminum plate protects neoprene rubber wear tires.
Delamination resistance and bending
Aluminum endings are "V" shape, and so protect against delamination and increase resistance to bending forces that occur in the circulation. Steel reinforcement in the corners of a device made from St.52.3 and so make the armature of the entire structure.
Reduced pressurek
Approximately 40% greater surface adhesion of the device similar design greatly reduces the transmission of unwanted pressure on the structure and minimizes the tendency toward long-term plastic deformation when the unit is stretched in the winter.
Smoother ride
COverall structures (transition from asphalt to neoprene, and the aluminum and neoprene ...) ensures a quiet and safe traffic.
Ease of installation
Significantly reducing the force of expansion and contraction when asked expansion joints as far as adjusting the correct temperature.
Reliability
Reliability guarantees the material from which are formed transitional devices. It is neoprene made to specification DIN 4141-140:1991 that define: tensile strength, elongation, strength, pressure and resistance to ozone.
Curbs and tactile
Parts of the device, crossing the road at the pedestrian zone, produced by welding at the correct angle in order to accurately follow the profile of the bridge.
Altitude
It is recommended that transitional device placed 3-5 mm below the surface level trošive asphalt, because experience has shown that there is erosion of the asphalt so that in the long run make would be exposed to traffic and wear.
