TECHNICAL INFORMATION

General

The DEMU Rebar couplers are used for mechanical connection of reinforcing steel bars B500B• system is available in bar diameters Ø12, Ø16, Ø20, Ø25, Ø32 and Ø40 mm• standard range comprises female socket bars as type 4010 (for Ø 40 mm as type 2010) and male connector bars as type 2020• for efficient installation connector bars can be tightened using assembly tool 2050 in combination with, e.g. an electric wrench• bar anchor 3016 with additional nailing plate is available to facilitate the fixing to the formwork • positioning coupler type 4015 can be used in situations where neither bar is freely rotatable, for example connecting bent bars or

closing distance between two fixed bars• all socket bars and connector bars can be supplied in non-standard lengths according to customer request• special double socket bars and connector bars types 4030, 4035, 2040• various bending shapes are available, standard reinforcement bending is done in the factory with 5 × bar diameter bends according

to BRL 0503, all bending shapes are KOMO certified• bending diameters have to be verified according to valid national standard, other bending diameters are available on request

Certification

DEMU Rebar couplers meet the requirements of guideline BRL 0504 “Mechanical Reinforcement Steel Couplers” and have been

certified by Kiwa. The reinforcing steel bars comply with EN 10080 / NEN 6008 grade B500B, nominal yield strength 500 N/mm²

and ductility class B. DEMU Rebar couplers are certified for cutting and bending according to guideline BRL 0503 “Tack welded

reinforcing mesh, reinforcing structures and bending and interweaving”. Only KOMO-certified reinforcing steel in accordance with

BRL 0501 „Reinforcing Steel“ is used.

Strength

Static applicationThe couplers can be used as a full-strength joint in static applications according to EN 1992-1-1, section 8.7 for reinforcing bars grade B500B in accordance with EN 10080 / NEN 6008. To ensure 100 % load transfer in both tension and compression the mechanical splice is designed for failure loads of 108 % of characteristic yield strength of B500B reinforcing bars. The couplers have been tested for predominantly static applications to sustain fatigue loading of two million cycles with a stress range of 2σa = 60 N/mm² and an upper stress of 0,6 × Re without failure.

Fatigue strengthSocket bars 4010 and connector bars 2020 for diameters 20 mm and 25 mm reinforcing bars are specified for use in concrete structures which are subjected to fatigue loading, for example bridges or foundations for machinery. The characteristic fatigue strength is determined by 2σa = 66 N/mm² at two million load cycles, tested with an upper stress level of 0.6 × Re according to the requirements of BRL 0504. To guarantee specified strength values, apply the correct torque values when installing the bar (see page 21).

Installation

An extensive range of accessories can be used for on-site installation of the rebar couplers. Types 2250, 2275, 2280, 2282 and 2600 guarantee optimal fixing of the socket bars to formwork. Plastic sealing caps 2244 protect the sockets against ingress of dirt and water. For further protection we also advise greasing the internal thread. A torque wrench to ensure connections are correctly tightened is available. For further installation instructions, see page 21.

TECHNICAL INFORMATION

General

Design

Flash-butt welding is not permitted in areas of non-predominantly static loads.Please note for Ø 20 and Ø 25: if welded steel is used only requirements of category 1 can be fulfilled.Welding can influence the material properties nega-tively. For this reason welding or applying heat to bend-areas is prohibited. DIN EN ISO 17660 is to be observed.HALFEN is not liable for any damage caused to or by DEMU products that have been subsequently welded.

All steel products in this catalogue are weldable. However, any welding, including tack welding, of DEMU products can infl uence their mechanical properties negatively. Welding can aff ect the

performance of the product. If welding in the application is unavoidable, take the following into account:

• a possible change in performance; a possible reduction in load capacity

• remove any coating layer before welding, and ensure welding fumes are safely extracted during welding

• use mandatory protective equipment

• the customer is responsible for making sure that applicable welding regulations are respected

The DEMU Rebar couplers design loads are based on the load capacity (yield strength) of the reinforcing bars. In addition, the minimum anchorage length of the bar embedded in the concrete has to be verified according to EN 1992-1-1, chapter 8.4 “Anchorage of longitudinal reinforcement” (NEN 6720 art. 9.6 and 9.16).

The required bonding strength depends mainly on the concrete strength class and needs to be verified. Please note that reduced anchorage length leads to reduced load capacity.

The DEMU Rebar couplers reinforcing bars are manufactured to a tolerance of +5 mm / −2 × diameter of bar. The existing anchorage length of the reinforcing bars may be calculated as follows:

Calculation of anchorage lengthLbd = L − l − 2 × D [mm]with Lbd = anchorage length [mm]L = total length of the male or female connector [mm]l = length of coupling (sleeve or thread) [mm]D = diameter of the rebar [mm]

If special lengths are required by the customer, HALFEN may produce them by using flash-butt welding according DIN EN ISO 17660. HALFEN plants are certified for performing butt welding acc. DIN EN ISO 17660.

The female socket bars and male connector bars must be stored so that they remain free of dirt to ensure both can be easily connected. For further protection against ingress of dirt and concrete sludge, we also advise greasing the inside of the sleeve. Male connector bars should be tightened using a torque wrench set to the correct torque value.
