5 Better safe than sorry The right channel for every application Besides excellent adjustability HALFEN Cast-in channels save considerable installation time. The result: faster construction and therefore cost saving. HALFEN Cast-in channels are the ideal basis for easy to install, adjustable connections. A foam strip filler stops the ingress of concrete into the channel. HALFEN HTA-CE Cast-in channels Application fixing of all types of building components NEW: HTA-CE 0/0P and HTA-CE 0/P with more load capacity. NEW! HALFEN HZA Cast-in channels, serrated Application fixing of all types of building components HALFEN HZA-PS Cast-in channels, serrated Application fixing of all types of building com ponents in safety critical areas of nuclear power stations and similar nuclear facilities HALFEN Channels are suitable for various types of construction connections, for example: façades, precast concrete elements, stadium seating, in civil engineering (fixing of tunnel signals) lift guide rails, crane runway, pipe fixings under bridges. HALFEN fixing systems The intelligent alternative to drilling and welding. Features adjustable hot-rolled profile; suitable for dynamic loads can be installed in concrete pressure and tensile-stress zones Features adjustable load transmission in longitudinal channel direction can be installed in concrete pressure and tensile-stress zones suitable for dynamic loads* *applies for all hot-rolled and serrated DYNAGRIP channels Features as HZA Channels suitable for exceptional load cases caused by earthquake, place crashes or explosions for concrete crack widths up to. mm HALFEN HGB Handrail connections Application fastening banisters on the thin front face of balcony slabs Features the special ribbed head anchor provides good load transfer in thin concrete elements 0 HALFEN B.-E

6 Channel range and steel load capacity/tension HALFEN has enhanced its anchor channel range; two new channel profiles are now available: HTA-CE 0/P and HTA-CE 0/0P. The different profiles can now cover a significantly higher load range, providing up to % more load capacity. Therefore allowing more economical solutions. Load capacities for HALFEN Channels hot-rolled, serrated 8/ 9/0 / 0/ 8/ 8/ Load capacities for HALFEN Channels hot-rolled also see illustration below 0/0 0/0P 0/ 0/P 9/0 / / Load capacities for HALFEN Channels cold-rolled, serrated Load capacities for HALFEN Channels cold-rolled / N Rd,s,c [kn] / / /8 HTA-CE with improved load capacity (Illustrated: Steel load capacity/tension) /9 0/ 0/P 0/0 HALFEN Anchor channels with increased load capacity! 0/0P NEW! New: HTA-CE 0/P Previously, for a load of N Ed >. kn the next larger channel had to be selected; a HTA-CE 0/0 (with N Rd,s,c =. kn) instead of a HTA-CE 0/. Now in most cases the HTA-CE 0/P (with N Rd,s,c =. kn) is sufficient. This also allows a more economical screw to be used; a HS 0/ instead of a HS 0/0. HTA-CE 0/0P Previously, for a load of N Ed >. kn the next larger channel had to be selected; a HTA-CE / (with N Rd,s,c = 0. kn) instead of a HTA-CE 0/0. Now in most cases the HTA-CE 0/0P (with N Rd,s,c =. kn) is sufficient. On-site safety: In many projects, different applications are therefore possible using a single channel profile. This reduces the risk of confusion when using different channels in one project. Furthermore, fewer bolt\screw types are required. Minimal channel size for economical reinforcement layouts: In respect to its load bearing capacity the new HTA-CE 0/P can almost always be used instead of a HTA-CE 0/0. With a height of only mm, the new channel is almost always installed completely in the required concrete cover. This allows more efficient reinforcement planning (mesh and supplementary reinforcement). European certification: The new HTA-HTA-CE 0/P and HTA-CE 0/0P types are included in ETA-/0 and are therefore certified for use, without restrictions, in 0 European countries..kn.kn 0.kN.kN N Rd,s,c [kn] (Channel / Anchor) 0 0 HALFEN B.-E

7 HALFEN Cast-in channels HTA-CE The advantages at a glance Apart from excellent adjustability, HALFEN Cast-in channels save considerable installation time. The result: faster construction and therefore reduced overall cost.

In case of shear stress, add bolt flexure to the tensile force. -KF Removing the strip filler Grip the strip filler at one end and pull out in one piece by hand, use a tool, e. g. a screwdriver. Safe assembly with HALFEN Cast-in channels HALFEN Bolts can be inserted anywhere in the channel slot, turned 90 and then locked in place by tightening the nut. Do not position bolts at channel ends past the last anchor. On channels with bolt anchors, the anchor locations are visible through the channel slot. Check Bolts: After installation check that the bolts are properly aligned; the notch or notches in the tip of the shank must be at right angles to the longitudinal axis of the channel. Fixings The bolt heads must sit flush on both lips of the anchor channel and be secured by tightening the nut with a torque wrench with the required value. Observe the torque values in the tables on page.

27 HALFEN CAST-IN CHANNELS HTA-CE Software HALFEN Software HTA-CE The HALFEN calculation program for HALFEN Cast-in channels according to the ETA provides the user with a convenient and very powerful calculation tool. Verifications CEN/TS 99- and EOTA TR0 require a wide range of verifications for cast-in channels and the concrete used. These verifications are processed by the user-friendly HALFEN software. In just a few seconds the user is presented with a list of suitable HALFEN Cast-in channels for the relevant load situation. Boundary conditions The calculation takes into account all necessary boundary conditions, typical examples being: cracked or non-cracked concrete the geometry of the concrete components, in particular the distances from the channel to the component edge various reinforcement patterns consideration of several dimensioning or characteristic loads positioning of the loads with a definable adjustment range, and the option of shifting the defined bolt pattern along the complete channel length verification of the required HALFEN T-head bolts and if required also for stand-off installations engineering consideration of fatigue loads and fire influence Input The geometry and loads are entered interactively. Entries are displayed promptly in a D graphic. Entries can also be changed directly in the graphic. Click on the load, the measurement or the component line you want to change to make the required modification. Results After calculation, the software output provides either the results for a preselected profile, or in the case of automatic selection a list of all suitable profiles. Profiles and T-bolts with in-complete verifications are highlighted in red.

Green check-marks indicate successful verifications. Red check-marks indicate unsatisfactory verifications. For further visual control a progressbar on the right indicates the status of the verification process. Here too, red bars mean that a load has been exceeded, while green bars symbolize verifications that meet the criteria. Detailed calculation information (with load positions, section sizes and utilization factors) can also be selected in a tree menu. After selecting a HALFEN Cast-in channel and suitable bolts, the dimensioning results can be imported into the data list and saved. Tender text Print-outs Print-outs are possible in a brief and in a verifiable long version. The long version includes all decisive verifications, a diagram of necessary reinforcement and a D graphic of the geometry and load.

40 HALFEN HGB HANDRAIL CONNECTIONS General Regulatory requirements Balconies are part of the structural system. "They must be designed, constructed, maintained and modified in such a fashion that public order and safety, especially to health or life, is not endangered". (MBO = Musterbauordnung / model building code 0 and construction guidelines). Technical guidelines issued by public notice as technical building regulations must be observed.* Technical rules provide information on load parameters, calculation, dimensioning of structural products, construction types, structural layouts etc. A requirement of regional building codes refers to structural stability: "All structures must, as a whole and in its individual components, be structurally self-supporting". This stability must be statically verifiable based on current technical standards. A further building regulation addresses traffic loads, for example: Balconies and loggias must be fitted with safety rails to prevent falls when they border on to an area with a drop of more than one metre. For a drop height up Regulations, standards and directives (to be observed when designing safety rails) Regional Building Codes VOB Part B,, execution of construction: BVM Directive Other applicable regulations and standards (Extract): to m the minimum banister height is 0.90 m measured from the upper surface of the finished floor surface or accessible ledge. For drop heights greater than m the banister height must be at least.0 m. For exceptions see the German Federal building regulations / Deutsche LandesBauOrdnung. Other regulations, not covered here, address the design, dimensioning, required spacings in the guard rail design, fire protection, thermal/sound insulation and rainwater drainage. * through the highest construction supervision authorities of the German Federal States Individual regional states have their own building codes and regulations. All current technical regulations require proof of structural safety and integrity. A static calculation or a building authority certificate is required when designing and dimensioning the fixings for guard rails.. () It is the contractor s responsibility to provide the static documentation in accordance with the contract. He has to observe the recognized standards of practice as well as with the provisions of the law and regulatory directives. VOB (Vergabe- und Vertragsordnung für Bauleistungen / Tender and Contract Regulations for the German building industry) Part B,., requires the contractor to report to the customer, in writing, any obvious design flaws, which he as the expert must be able to recognize. He alone is responsible for any resulting defect and consequential expenses. If he has satisfied his reporting obligation, the responsibility for the defect passes to the customer (defect example: banister attachment mounted in too thin a concrete slab).

44 HALFEN HGB HANDRAIL CONNECTIONS Dimensioning Fundamentals Banister height The minimum height h b of a banister is 0.90 m from the top surface of the finished floor or accessible ledge to the upper edge of the rail. For drop heights of more than.0 m the banister must be at least.0 m in height. (Exceptions; as specified in regional building codes) It would be advisable to have one uniform minimum height of.00 m as has already been mandated in the commercial sector and in a number of European countries. Balcony slab Anchor channels or dowel installations require concrete of at least C 0/ grade. If the concrete grade is less than C 0/ grade or it is unknown a case-by-case decision must be made. The thickness of the balcony slab must be at least h = 00 0 mm when the HGB is mounted in the slab edge (depends on channel profile and according to German HGB approval). Other types of installation and systems require a thicker slab. All weather-exposed concrete-embedded installations (e.g. for balconies) must be made of stainless steel. Spacings Any structural design must take all basic requirements for railings and banisters into account. As a general rule, all railings and banisters must be designed so that personal injury is ruled out, for instance with correct spacing of rails, lattice bars or panels. They should also be designed so as not to entice but instead to discourage anyone from climbing over. The specific requirements for guard rail design are determined by the intended use (residential, public, commercial) and the drop height involved. Also observe the building codes of each country or region, the ETB guidelines Fall Protection Components and DIN 80 (Stairs in Buildings definition, rules, key measurements) and guard rail regulation applicable at the construction site. In Germany these are the Geländer-Richtlinie 0 (BVM Berufsverband Metall), Federal Association of German Metalworkers. b Rail height hb OK FF h b = clear distance between the back of the veneer and the front face of the balcony slab or gutter / kick plate clear distance between bottom edge of hand rail and top edge of facing / lower structure clear distance between the top edge of the finished floor and the bottom edge of the facing / lower structure axis spacing between posts clear distance between horizontal facings clear distance between vertical facings 0 HALFEN B.-E

Rafter roof static system: F,d < FRd F,d FN,d The maximum rafter strength is limited by the design load of each individual component of the rafter shoe. Load tests resulted in a mean breaking load of 0 kn. With normal loads larger than the recommended load capacity (= about ⅓ of the breaking load), the rafter spacing may need to be reduced. If lower loads are present then the minimum edge distance C, for the HALFEN Cast-in channels can be reduced. The distance to the concrete edge must be at least 0 mm. Make sure that the HALFEN Cast-in channels are installed flush with the concrete surface. Use spacers if necessary. 0 0 HALFEN B.-E

73 HALFEN CURTAIN WALL SUPPORT SYSTEMS HCW General HALFEN Curtain wall system This type of construction is characterized by an outer wall with a continual outer skin (see figure ). The façade is attached to the main structure of the building using only the required number of point-load connections. Curtain wall façades protect the interior of buildings from external, unwanted environmental influences whilst still Post and beam façade and the modular façade Basically, we distinguish between two methods of curtain wall façades constructions: the post and beam façade and the modular façade. Post and beam façade One basic distinctive difference is the way expansion in the façade is distributed (for example; thermal expansion). With the post and beam façade (see figure ) the vertical and horizontal frame supports are installed in spacings corresponding to the façade elements. The supports are installed with an expansion gap between components allowing for sufficient expansion. The respective longitudinal and transverse connections have an expandable joint. The filler elements (glass or panel) installed in a post and beam structure permit movement within the tolerance of the designed expansion joint. The glass and filler elements are delivered separately and are then installed on site, requiring on-site scaffolding. permitting visual contact with the outside environment with structural components that can be opened or are transparent. Specifically, this includes sufficient stability against wind loads, adequate insulation against frost in winter, heat in summer as well as against external noise. In addition, various requirements must be met to protect against fire and other critical situations. Post and beam façade Plan View Modular façade With the modular façade method (see figure ), the façade is made of prefabricated elements, in which glass, natural stone or infills are pre-installed. The façade profiles are designed as a key and slot system to allow for expansion. Curtain wall Figure partial view of a façade Plan Modular façade section Figure View Figure This method provides immediate weather protection and allows the building contractor to start interior work on the respective floor directly after the prefabricated modules have been installed. Scaffolding is not required with this method of construction. HZA Channels HTA-CE Channels 0 HALFEN B.-E

Forces acting on the T-head bolts at the channel (HCW-ED) The design reaction forces components in the HALFEN Bolts at connection curtain wall bracket to HALFEN Cast-in channel are calculated by multiplying the design loads F vd and F hd at connection curtain wall bracket and façade support post with the factors s x, s y and s z. The factors are dependent on the bracket geometry, the load direction and the bolt position (see figure on the right). See table below for the multiplication factors for determining the design reaction forces in the HALFEN Bolts.
