Fixed steel formwork for concrete floor

 Arfen Slab Joint SJ 185 fixed steel formwork is a profile for arranging concrete floors, expansion joints and protecting the edges of concrete slabs from mechanical damage. The steel profile is installed before pouring concrete and after concreting remains inside the structure, performing the function of fixed formwork and a protective element for the expansion joint.

The steel profile for concrete floors is designed for facilities where the surface is subjected to intensive use, shock, vibration and dynamic loads. The profile protects the edges of concrete tiles from chipping and destruction, helps to preserve the geometry of the floor and extend its service life.

Where fixed formwork is used

Fixed steel formwork for concreting is used during the construction and repair of industrial concrete floors, warehouses and production facilities. The profile is suitable for areas where warehouse and heavy machinery are regularly moved.

Main areas of application:

• industrial concrete floors;

• warehouses and complexes;

• logistics centers;

• manufacturing enterprises;

• parking lots;

• ports;

• airfields;

• concrete platforms;

• areas with heavy traffic of forklifts and other equipment.

Advantages of steel profile for expansion joints

The use of steel fixed formwork allows for additional protection of the concrete structure in the most vulnerable area - at the edges of the concrete slabs.

Main advantages:

• high strength and resistance to shock and dynamic loads;

• protection of the edges of concrete slabs from chipping and destruction;

• reducing wear of concrete edges during the movement of machinery;

• minimizing the risk of cracks due to shrinkage and temperature fluctuations;

• preserving the geometry of the concrete floor;

• increasing the service life of the concrete surface;

• displacement compensation up to ±7 mm ;

• no need to dismantle the profile after concreting.

Construction of fixed formwork Arfen Slab Joint SJ 185

The profile consists of several elements that ensure its fixation and correct formation of the concrete structure:

1. The upper flat steel "lip".

2. The lower steel plate is directly the formwork, with a height of 115 mm to 300 mm.

3. Anchors cast into concrete: D = 10 mm, length 100 mm, pitch 250 mm .

4. 8 mm thick pouring plate and ABS plastic overlay.

5. Leg for attaching to the base is optional.

6. Height calibration plate is optional.

7. Plastic bolt for breaking made of polyamide.

Profiles can be made of structural, galvanized or stainless steel . Stainless and galvanized versions can be used for objects with high humidity or aggressive environments.

Installation of fixed steel formwork

The expansion joint profile is installed before concreting. It is placed along the boundaries of the concreting maps and fixed in accordance with the profile design. After pouring the concrete, the steel formwork remains inside the structure.

During operation, the profile protects the edges of concrete slabs from mechanical stress caused by traffic, impacts, vibrations, and other loads.
