27.11.2017 - New catalogue: HALFEN Tunnelling

Tunnels are very challenging civil engineering projects with a prospective service life of 100 years or more, and therefore the highest standards for installation of safety relevant fixing are required in their construction.

Our new tunnel catalogue provides an overview of the wide range of HALFEN products used worldwide for fixing in tunnel construction that meet these standards.

The catalogue illustrates examples from Europe, the USA and China of applications in railway tunnels, in road tunnels and in utility service projects.
The first part of the catalogue is a general overview of products to provide easy orientation of the applications followed with a compilation of technical information for the illustrated products.

If you have any questions or require individual consultation for a project, please contact our tunnel team at: kap.tunnel@halfen.com.

04.09.2017 - HALFEN HIT Balcony Connections: 2 hour fire protection as standard

Structural fire protection is a complex issue that should not to be neglected. Interpretation of the regulations and their correct application requires comprehensive know-how.

An uncomplicated and above all a reliable solution is available for balcony connections. Class A1 rock wool material is used in all HALFEN Insulated HIT-HP and HIT-SP connection elements for energy-efficiency, and also for fire protection. Consequently, HIT elements meet the highest fire resistance REI 120 classification as standard.

08.03.2017 - Fewer movement joints with the new HALFEN HIT Insulated connections

Following amendments to the DIBt approval Z-15.7-293 in November 2016 and further changes to technical approvals, Z-15.7-312 and Z-15.7-309, the distance between movement joints for propped balconies, access walkways and continuous parapets has increased by more than 100% to 23 metres.

HALFEN HIT Insulated connections fulfill the highest fire protection requirement according to REI 120 as standard. You can find our products as (Tekla) building components in BIM libraries and on the HALFEN PARTcommunity as CAD drawings. To ensure economic planning, HALFEN provides the HIT design software and a HALFEN ψ-calculator. Contact HALFEN at technical@halfen.co.uk, tel. 01582 470 300

23.01.2017 - Video: HALFEN HIT Insulated connections for cantilevered structural components and balconies

Welcome to our HIT-Show house: sit back and enjoy the tour! This unique, virtual building contains numerous examples of our HIT insulated connections in use.

With its HIT Insulated connections, HALFEN provides a versatile and innovative range of products. The connections not only ensure optimum thermal insulation, they also fulfill the highest fire protection requirements as standard and can be used in many different installation situations.

You can find our products as (Tekla-) Buildings components in the BIM-Library and under HALFEN PARTcommunity as CAD drawings. HIT planning software is available to ensure efficient planning.

We will also gladly provide you with solutions specifically developed for your individual building projects. Contact us at: technical@halfen.co.uk, Phone: +44 1582 470 300.

16.01.2017 - HALFEN sets new standards with the HTA-CE Plus!

The classic anchor channel is now ready for a leap in its evolution: Thanks to outstanding engineering improvements and multiple optimized details  a new, more efficient HALFEN channel is now available.

The innovative hot-rolled HALFEN HTA-CE plus channels provide you the following benefits:
  • Due to the new, higher load range more applications can be covered with the new HTA-CE 40/22P and HTA-CE 50/30P channels. This reduces the risk of channel and bolt confusion on your construction site and in your precast plant.
  • When selecting the new HTA-CE 40/22P for higher loads, the HS 40/22 bolt is used. In comparison to previous solutions using the HTA-CE 50/30 you also reduce costs and the number of different bolts that are required on construction site.
  • With the new plus channels you can now select smaller profiles for the same loads requirements. The HALFEN channel with a height of only 23 mm (HTA-CE 40/22P) and 30mm (HTA-CE 50/30P) is almost always installed completely in the required concrete cover. This allows more efficiency to your reinforcement planning.
  • For more ambitious constructions the curved HTA-CE-CS, HALFEN channel pairs, corner elements and customized elements are available as options. HALFEN bolts and the complete portfolio are available in the current B17.1-E technical catalogue.
The new HTA-CE 40/22P and HTA-CE 50/30P channel profiles are approved with ETA-16/0453 for use in Europe and are CE marked. They can be easily and efficiently calculated using the HALFEN HTA software. After selecting a HALFEN channel and a suitable bolt the calculation results can be easily copied in a list and saved in a file. Click here to download the current HTA software.

You also find our HALFEN channels as (Tekla-) building element components in BIM libraries and as CAD drawings in the HALFEN PARTcommunity.

09.01.2017 - Larger required spacing between expansion joints in cantilevered balconies, access balconies and parapets

In November 2016, the General Building Authority (DIBt, Deutscher Institut für Bautechnik) approval no. Z-15.7-293 for the HIT Insulated connection element was amended to include the updated expansion joint spacing. The substantial increase in the maximum allowable spacing of the expansion joints significantly extends the range of applications for the HIT Insulated connection elements. This includes the following advantages when planning:

  • the lengths of individual balconies, access balconies, and parapet elements can be designed up to twice as long as previously possible
  • increased flexibility and planning for external and internal corner balconies
  • façade expansion joints up to 23 meters are now possible in parapets
  • reduction in time and effort required for formwork, reinforcing and concreting
  • flexible planning of concrete sections
  • more effective use of transport lengths with prefabricated balconies
In addition, the HIT-HP with 80mm insulation thickness and the HIT-SP with 120mm insulation thickness fulfil the highest fire protection requirement according to REI 120 as standard, and can be used as fire barriers without requiring further measures.

You can find our products as (Tekla) building components in BIM libraries and on the HALFEN PARTcommunity as CAD drawings. To ensure economic planning HALFEN provides the HIT design software and a HALFEN ψ-calculator. Contact HALFEN at: ti.stahlbeton@halfen.de, phone: + 49 2173 / 970-9030.
