HSC-B Concrete steel connection System face plate for beam connection, fin plate connections or other constructions. authority ng Z o N t pr. Ap DIB ed The HALFEN HUC Universal connection high performance system is an effective solution for transfer of high structural loads into concrete. The HUC system includes the cast-in concrete HSC-B Steel connection and the secondary connecting unit. For example, the HSCC Steel corbel. The flexibility of the HSC-B Sockets and the positive transfer of forces permit an extensive range of applications. For example, connections for steel beams, steel corbels, cable bracing systems or anchor points for the DETAN Rod system. HALFEN HSC-B Concrete steel connection Buil di HALFEN Universal connection s ystem ov appr p Ty ed est e-t r b el FEN AL co See page 3 for further application examples HALFEN HSCC Steel corbels To optimize the planning process HALFEN has 34 type-tested HSCC Steel corbels available. In comparison, HSCC Steel corbels provide up to double the load capacity of concrete corbels. In combination with a chamfered beam the total installation height can be significantly reduced. This significantly reduces the construction height normally required for support corbels, see page 16.

5 HALFEN HSC-B Concrete Steel Connection Installation example HALFEN HSC-B Concrete steel connector for 2 x 4 HSC-B SH socket bars for connecting a steel beam to a reinforced concrete column. 1. Remove the thread protector. 4. The positioning plate with its attached socket bars is secured either with a magnet to steel formwork or with nails to timber formwork. 7. After the concrete has been poured and has cured, remove the formwork and replace the thread protector to prevent corrosion until final installation. 2. Connect the HSC-B SH socket bars to the positioning plate using flat head bolts (3 mm head). 5. Place the column reinforcement and any additional reinforcement according to the structural engineer s specifications, see also page 14 ff. Variant: Flush mounted positioning plate; screw penetrating the formwork. 3. Cut and attach self adhesive foam stripes to form a recess at the connection location and to prevent concrete seepage. Place a magnet in the centre of the positioning plate to secure position when using steel formwork. See page 8 for further accessories. positioning plate formwork Further information including details on anchor placement can be found in the HUC assembly instructions. Available at 8.

9 HALFEN HSC-B Concrete Steel Connection Design and dimensioning according to German Approval Z The German Approval regulates the placement of HSC-B connecting elements in concrete components, including calculation and constructive demands. The following illustrates the use of the HSC-B; information applies to both single as well as double ended connections. Building Authority Approval requirements must be observed. Verification of connected steel elements and the bolts must also be provided. Suitability of the reinforced concrete for expected loads has to be verified. Materials normal concrete, strength class C20/25 up to C70/85 HSC-B-bar: B 500 B diameters mm Socket corrosion protection hot-dipped galvanized (fv) stainless steel (A4) electro plated (gv) Stress and resistance predominantly and non-predominantly static loads yield strength of reinforcement steel f yd = f yk s = 500 N/mm² 1.15 = 435 N/mm² HSC-B Socket bars; fatigue resistance values Dynamic loads The use of spring washers for installation of face plates is recommended if the HSC-B is subjected to dynamic loads. Preload stress, torque moments Preload stress and torque moments should not be greater than the values for bolts assumed for strength class 5.6. Hole layout Depending on requirements, the number of HSC-B is freely selectable. Single row and multi row anchorage is possible. Minimum spacings must be observed (see table). The positioning plate should have a slightly larger footprint than the face plate, see page 6. The maximum hole diameters in the face plates of attached components should also not be exceeded. See adjacent table. Screw length When calculating the screw length, the minimal screw depth of 1 d s for final installation must be observed. The maximum bolt screwdepth L 1 (see table below) is determined by the anchors socket size. face plate d L Dimensions, geometric requirements HSC-B bolt minimum distances d s [mm] [-] a ij,edge [mm] a ij [mm] u [mm] hole diameter max d L [mm] 16 M M M min 1 d s L 1 Maximum bolt screw depth HSC-B d L 1 [mm] s [mm] stress ranges for N = : Δ RSK = 80 N/mm² for d HSC-B = 16 mm and d HSC-B = 20 mm Δ RSK = 70 N/mm² for d HSC-B = 25 mm Wöhlerline stress exponents: k 1 = 3.5 for N k 1 = 3 for N 10 7 k 2 = 5 Hole pattern minimum spacing u a ij,edge a ij a ij a ij a ij,edge Detailed dimensioning examples available at HALFEN HUC 12-E 9

Type test according to DIN and Eurocode 3 The type-test includes all verifications for the steel connecting elements as well as the verifications for the transfer of forces into the reinforced concrete. Decisive for load capacity is the smallest resistance value from all verifications. The stated load capacities are for effects of predominantly static loads and apply for single and double corbels. A horizontal load of H Ed = 0.2 F Ed has been considered. When verifying, the transfer of acting loads and calculating the dimensions of reinforced concrete elements depend on the circumstances in each individual case; these are not included in the type-test. The verifications for steel element are according to DIN and Eurocode 3 (DIN EN 1993). In addition, for each corbel type, the load capacities for bolts strength classes 8.8 and 10.9 were calculated, in some cases adapting the number of bolts. Please refer to the type-test for the position of the sockets for each individual bolt. Place a bearing plate (for example an elastomer plate) on the corbel flange to ensure an even load distribution. See tables on page 20 ff. or the type-test for dimensions. Load transfer into the reinforced concrete element were verified according to the guide-lines set in Building Authority Approval Z Please observe the notes on pages The specified, required, bursting reinforcement for loads (maximum yield) for large column widths include a safety margin. Please note the minimum diameter for reinforcement bars, see page 14. Further information for calculating the actual required bursting reinforcement for individual applications can be found on page 14. Separate verification is required for possible stirrup reinforcement in the column. Anchoring (full anchorage) the socket bars with HSC Anchor-heads is according to Approval Z See notes on page 15. Alternatively, other anchorage variants can be used; additional verification is required here. The following tables are for bolts, strength grade 10.9 where the calculation for the steel element was based on Eurocode 3. In some cases, assuming the same load capacity, fewer bolts are required in applications calculated according to DIN than when calculated according to Eurocode. Further calculation examples as well as all relevant details can be found in the type test. Type tests are available for all types of corbels; download at HALFEN HUC 12-E 19
