5 Stabox & Coupler Stabox & Coupler Modern reinforced concrete construction is no longer imaginable witout te Stabox rebend connection and te Coupler screw connection from FRANK as well as teir countless variants and product combinations. Tese reinforcement connections enable te force-locked connection of reinforced concrete elements wic are manufactured and concreted in several building pases on account of rational formwork systems. Wit te Stabox rebend connection and Coupler screw connection a defi ned force lock is possible in te concrete joint for te subsequent concreting of ceilings, walls, corbels and oter steel reinforced concrete structural elements.

8 Stabox product description Stabox S In most applications te standard use of reinforcement boxes in building practice requires a defi ned transverse force transmission. Due to its geometry, wic is armonised wit te Eurocode and National Appendix, te Stabox S standard reinforcement connection meets te igest transverse force requirements for an indented working joint. Practical example of te formation of a concrete working joint wit rebendable reinforcing steel in a reinforcement box wen building a veicle ramp (fi g. page 6). Stabox T In te case of wall or ceiling slabs, for example, very ig sear forces can be inducted into te working joint due to wind loads in te element direction. In tis case te Stabox T reinforcement connection meets te igest requirements for an indented working joint. Practical example of a working joint connection wit maximum sear load: Wall/beam connection (fi g. page 6). Stabox F Building site-compatible solution for te sealing of working joints wit continuous reinforcement. Te Stabox reinforcement connections simplify te formworking of concrete working joints. If te reinforcing steel as to be routed troug te water-stressed working joint due to static loads, te Stabox F wit integrated Fradifl ex metal waterstop simultaneously enables a secure joint seal according to te guideline for watertigt structures. 8

Geometrical use of te concrete load bearing capacity troug load distribution indented joints Te geometrical requirements for te igest possible category indented joint are defi ned in Eurocode 2, DIN EN wit NA(D) and te DBV data seet Rebending of reinforcing steel and requirements for reinforcement boxes. Indentation transverse to te box Te Stabox S reinforcement connection fulfi ls tis igest requirement indented for all load cases wit load V Ed transverse to te box (LF: c, d, e, f). A iger calculatory formulation for te values of rougness [c] and friction [μ] tan te surface property indented is not possible for te calculation of te absorbable transverse force V Rd. Indentation in te element direction Te Stabox T reinforcement connection fulfi ls te igest requirement indented for all load cases wit load V Ed in te element direction of te box (LF: a, b). Te addition of te Stabox T reinforcement box to te product range also enables te maximum formulation of te values for rougness [c] and friction [μ] of te surface property indented for te calculation of te absorbable sear force V Rd in te case of sear loads. Watertigt working joints for watertigt structures Te coated Fradifl ex metal waterstop integrated in te Stabox F continues te fl oor-wall working joint seal witout an interruption. Te Fradifl ex metal waterstop can also be used for pressing water loads up to a continuously acting ydrostatic pressure of 2 bar (20 m water column). 10

11 Stabox principles Special sapes Te sapes and dimensions specifi ed in te planning as well as structurally necessary bending sapes of te reinforcement place particular demands on rebendable reinforcement connections. Te FRANK Stabox S and Stabox T reinforcement boxes offer numerous possibilities for special dimensions and sapes. Formworking is tus signifi cantly reduced in te most diverse applications troug te use of te Stabox reinforcement connections. Overlap lengt Wit te standard types of te Stabox rebend connections, te stirrup dimensions suc as stirrup eigt and overlap lengt are manufactured in accordance wit te Stabox type static calculation and type test report. Te overlapping joints in te 2 nd concrete pour are to be executed in suc a way tat a full joint of te reinforcement of te rebend connection is formed. To do tis, te bars used as te reinforcement in te 2 nd concrete pour must ave at least te same diameter as tose in te Stabox rebend connection and are to be taken directly up to te concreting pour joint. Te overlap lengt of te rebend connections in te 2 nd concrete pour depends on te respective reinforcing steel diameter. Type static calculation and type test report Te Stabox reinforcement connection defi nes te current state of te art. Te furter processing of te reinforcing steel insert B500B in te factory according to DIN 488 wit guaranteed rebending capability is cecked by bot in-ouse and external supervision and confi rmed by te U mark.

16 Stabox rebending d s d s/3 Rebending and rebending tool Te bending and rebending of reinforcing steel canges te material properties in te deformation area affected.

All requirements in accordance wit specifi ed current rules are taken into account in te Stabox support structure tables. In order to minimise te negative effects on te material properties, te instructions for use and rebending must be observed on site. Please use a suitable rebending tool in eac case for te rebending of te bars (see table). Sligtly raise te steel insert and bend it out to an angle of 20 at te most. Using te rebending tool, bend te structural steel step by step until it is straigt. Wen doing tis, pus te rebending tool furter forward as sown in te diagram. According to te DBV data seet, te offset dimension sould be d s /3. Steel sould not be rebent at temperatures below -5 C. Multiple bending and rebending is not permissible.

29 Coupler special versions Coupler screw connection wit Stabox T element for sear indentation Prefabricated joint formwork elements for igly-stressed structural elements wit large steel diameters from 12 to 32 mm can be assembled in advance in te factory using Coupler screw connections. Due to te variation options wit te different joint formwork elements suc as Stabox S, Stabox T, Stremaform, Stremaboard or joint form profi le I, te elements can be manufactured in bot te transverse and sear directions as indented joints according to DIN EN :2011 (/NA: ). Coupler screw connections wit Stremaform formwork element Coupler screw connection in combination wit Stremaform indented joint. Te prefabricated joint element offers te structural engineer a reliable and safe way to implement is static requirements (category and reinforcement) for te working joint in te actual construction. Te elements are prefabricated in te factory for ease of mounting and building site compatibility. Tis minimises sources of error suc as incorrect rebar diameters or te disregard of te stirrup spacings during installation. Coupler screw connections wit ancor plate and mounting plate If te embedment dept or overlap lengt as to be sortened due to small structural element dimensions, tis can be solved by using ancor plates on CA socket bars and CE treaded bars. Mounting plates in te working joint can be used as simply defi ned mounting aids or as connections for structural steel components. Te ancor plates or mounting plates are manufactured according to te plan specifi cation or customer requirements. Coupler special accessories Coupler special accessories are available for te mounting of reinforcement bars tat are not freely rotatable in te second building section (e.g. stirrups for corbels).
