Attached formwork concrete expansion joint floor to TU U V. 2.6-24.3-21201441-009:2014 (alpha profile)

The alpha profile is a professional formwork for premium-class concrete surfaces with temperature-deformation seams. Has increased strength in comparison with other profiles for concrete. Used in the laying of foundations subjected to significant operating pressures, as with the threaded seams and a seamless, reinforced mesh, steel frame or a fibre, for soil foundations and bored piles. The alpha profile is designed to: - set the upper level of the plane of the floor; - planning time-temperature-deformation seam; - dock clip the edges of the concrete floor with newly poured concrete; - limiting of the concreting platform; - protection of floor edges from chipping (fracture). Benefits • Easy installation and Assembly. • Small weight. • High-straightness profile. • Ability to use as a guide when laying the concrete using a screed. • Limit the movement of the plates relative to each other in vertical and horizontal plane. Even when opening the seam up to 30 mm part of the key (45 mm) remains in the body of the concrete, continuing to accept and distribute the load.
The scope of Industrial and civil construction, where required laying of governmental industrial floors with high demands on abrasion resistance: hypermarkets, shopping centers, warehouses, production facilities of enterprises of food, light and chemical industry, machinery etc Road construction with road surfaces that can withstand high loads: bridges, overpasses, interchanges, crossings, runway. Description 1. Loop - lock alpha profile in concrete, provide disclosure of seam shrinkage. 2. Slat top steel strip to protect the edge of the seam. 3. The key case protects the key from a concrete mass adjacent the plate and does not prevent the disclosure of the seam. 4. The key is trapezoidal, made of steel with an ultimate tensile of~in not less than 400 MPa. Restricts vertical and lateral movement of the plates, but does not preclude the disclosure of the seam. 5. Special fasteners - provides the location of the two bands at the same level in the process of installation and pouring of concrete and erection of the seam during shrinkage. 6. Partition plate special design provides increased rigidity of the joint.
