HALFEN Cast-in channels Offering easy reliable and excellent adjustment, HALFEN Cast-in channels save considerable installation time for connections to concrete. The result: Faster completion of the construction project and reduced costs. • Approved for fire-resistant structural • Can be installed in concrete pressure • Suitable for dynamic loading • Building authority approval • Easy checking installation errrors • Safer for installers, without the health hazards caused by vibrating powertools, noise, dust, sparks, or • Adjustable component anchoring • Extremely economical • Installation with...

HALFEN HZA-PS CAST-IN CHANNELS HALFEN Cast-in channels, available hot- dip galvanized or made from stainless steel, have received building authority approvals by the German Construction Materials Supervisory Board (DIBt). Cast-in channels are set flush to the con- crete surface. The channels use T-bolts or toothed bolts with associated nuts and washers, to reliably secure struc- tural elements. Evaluation Report HALFEN Cast-in channel HZA-PS are suitable for applications in safety relevant areas of nuclear power plants and other nuclear facilities. They fulfill the higher requirements for taking...

HALFEN HZA-PS CAST-IN CHANNELS Safety Relevant Aspects For applications in normal concrete constructions such as office buildings, schools, industrial buildings or in non-safety relevant areas of nuclear power plants HTA & HZA channels are officially approved, and recommended. In such cases the typical maximum crack width within the concrete structure is Concrete cracks However for safety relevant areas in nuclear power plants or other nuclear facilities higher safety requirements for tak- ing impact loads from outside (EVA) or inside (EVI) must be considered. The suitability of the spezial HZA-PS...

HALFEN HZA-PS CAST-IN CHANNELS In nuclear power plants and nuclear facilities different requirement categories must be considered (see DIN 25449): Category A3: Loading cases which occur only one time during the lifetime of the facility: • Plane crash • Exterior explosion • Interior explosion • Differential pressure Category A2: Loading cases which occur less than ten times during the lifetime of the facility. Category A1: Loading cases which occur more than ten times during the lifetime of the facility. As a result of the higher demands of category 3 and 2 you have to consider wider concrete...

HA LF E N H Z A - PS CAS T- IN CHANNE LS Tests 3. Performance test in an opening and closing concrete crack 4. Cyclic load change in a wide concrete crack For this purpose 10 alterations of the concrete crack width between 1.0 and 1.5 mm were performed in a frequency of 0.2 Hz while the anchor channel was loaded with a constant tension load. Afterwards a pull out test in the widest concrete crack 1.5 mm was carried out. In this test the concrete crack is opened up to 1.5 mm and then a tension load is applied to the Cast-in channel. Then the Cast-in channel is completely unloaded. In this way...
