Product catalog summary

Overview: The Conecto Dowel system is designed to create expansion joints in concrete floor plates, ensuring even load distribution and preventing excessive local tensions that lead to floor cracking. This system enhances the durability and comfort of use of concrete floors.

Specifications: The dowel profiles are available in various sizes and materials, including steel grades S355 and S235. The standard profile length is 3,000 mm, with dowels available in sizes such as 180x120x8 mm and 180x140x10 mm. The system can accommodate different load capacities by varying the number of dowels per joint (5D, 6D, 7D).

Materials: The profiles are made from high-grade steel, with options for galvanized and stainless steel. The dowels are placed in plastic sleeves that allow horizontal movement while preventing vertical displacement.

Installation: The system is easy to install, requiring only the placement of joints at the site and securing them with screws and wing nuts provided in the package. The joints should divide the floor into regular fields, ideally squares up to 1,000 m², with a maximum spacing of 45 meters.

Load Capacity: The load capacity of the expansion joints varies based on the dowel size and number. For example, a 5D configuration with dowels sized 180x120x8 mm can handle up to 248 kN/lm at zero joint opening, decreasing as the opening increases.

Performance: The system is designed to handle high traffic loads and prevent damage at the edges of concrete plates. It compensates for horizontal movements due to thermal expansion and shrinkage while blocking vertical movements caused by traffic and heavy loads.

Standards: The load capacities are calculated in accordance with TR34 (4th edition), ensuring compliance with industry standards for concrete floor construction.

Technical data sheet Conecto dowel profiles Conecto Dowel system Conecto Dowel expansion joints ensure an even distribution of the loads between floor plates by preventing excessive local tensions. Expansion joints help to eliminate the main reason behind uncontrolled floor cracking, they make the floor last longer and improve use comfort. The number of expansion joints should allow to divide the floor into regular fields, with a shape similar to a square of up to 1000m2, which constitutes a daily flooring efficiency. Joints should be spaced at a distance not greater than 45m. The system is complete,...

Technical data sheet Conecto dowel profiles Conecto Dowel system Expansion strips are mounted in concrete floor plates to compensate movements in plate sections. Concrete plates are exposed to internal and external pressures. Damage occurs mainly at the edges of plates near to connections. Connection of floor plates should compensate their mutual horizontal movements (perpendicular and parallel to the expansion joint) which are usually caused by thermal expansion and shrinkage of concrete. At the same time the connection must also block vertical movements and mutual curving of floor elements...
