INTRODUCTION Terwa Rebar Connection System is a durable connection of reinforcement. The traditional way to connect reinforcement steel was to overlap and weld the reinforcement together. Terwa Rebar Connection System is a simple and efficient method to connect the reinforcement steel which eliminates the disadvantages of the traditional procedure. Terwa Rebar Connection Systems are based on a modern technology, which consists in metric thread couplers. The design of the couplers allows a connection of the reinforcement steel, where the characteristics are equal with an uninterrupted bar because the full pulling force (or pressure force) is transmitted by dynamic load. The shape and the metric thread allow an easy mounting on the construction site or in the prefab factory by using standard tools. The characteristics and advantages of the Terwa Rebar Connection System are: - It is used for reinforcement steel with a diameter from 10 mm to 40 mm. - The full diameter or cross-section of the bar can be used. - Full connection of the reinforcement. - Suited for dynamic loads. - Elongation below 0.1 mm. - Additional preparation for the reinforcement steel is not necessary. - Suitable for all types of reinforcement steel according to the European and American norms. - The couplers are designed for reinforcement steel B500B EN 10080 with a yield strength 500 MPa and a tensile strength 550 MPa. - The shape, height and the type of the ribs of the reinforcement steel have no influence on the connection. - Because the outside diameter has minimal dimension a better concrete cover is generated and a concentration of reinforcement steel can be prevented. - The contact surfaces of the couplers exclude the usage of lock-nuts. - Every diameter and length of the reinforcement steel, straight or bended, can be fitted with a coupler and can be easily connected. Installation: - It is no need for a nut-wrench to tighten the coupling. It has to be used a pipe-wrench or a torque wrench for the couplers tightening and to prevent the thread movement. - Special tools, power sources or special training of the personnel are not necessary. - The metric thread and the way of connection allow a fast and easy control of the connection. - The erection time is reduced to minimum. Characteristics: - The couplers are delivered standard galvanized. - There is variant in which the pressing coupler is made of stainless steel. Terwa Rebar Connection System is composed of: - Reinforcement steel B450C, B500B, B500C EN 10080. - A sleeve with interior thread type PKB, pressed at one end. - Two sleeves with interior thread type PKB, pressed at both ends. - Stainless steel sleeves pressed at both ends. - Position coupler TSK. - Fixing connectors KB or KBL. - Accessories for fixing. alterations reserved Mar-17 Page 4

Also other length L A and L B available on request: PSAG d x Length L A / L B in mm. For choosing dimensions L A and L B should take into account the minimum size according with the table 10. L A is the length measured from the front of coupler to the back of the reinforcing bar. The minimum dimensions for bending are presented in the following table. The diameter to which a bar is bent should be such as to avoid damage to the reinforcement and crushing of concrete inside the bend of the bar. According to Eurocode 2 minimum bending diameter should be: D Bmin = 4 x d for bar diameter d 16mm D Bmin = 7 x d for bar diameter d > 16mm Table 9 Reinforcing diameter d Thread L A min L B min Bending diameter D B min [mm] M [mm] [mm] [mm] 12 M16 160 125 48 16 M20 210 130 64 20 M24 230 190 140 25 M30 300 240 175 32 M42 370 325 224 4 x d 7 x d alterations reserved Mar-17 Page 13

TERWA END COUPLERS The Terwa End Coupler represents an efficient alternative for the traditional connections roof-column, beam-column or foundation-column. TERWA END COUPLER CLASSIC SOLUTION The traditional method consists in a hooked rebar anchorage The End Coupler it is highlighted by the next advantages: who comes with a series of disadvantages: Minimize the length of the rebar and reduce the congestion inside the concrete element; Requires longer lengths of anchorage which increase rebar congestion; Eliminate the hooks; More labor for the installation; Faster and simple installation; Longer time for execution; Simplifies the structural design; Hidden costs, especially for bigger diameters (the Better anchorage in the concrete element. lap length grow proportional with the reinforcement steel diameter); Lower safety on construction sites. Column Connection Figure 29 Figure 30 Foundation Connection Figure 31 Figure 32 Terwa End Coupler consists in a threaded round steel plate which fits with PSA-PSC connection or with TSE connection. Terwa End Couplers meets the ACI 318 and Eurocode 2 regarding the embedding lengths for reinforcement steel. The End Coupler is designed and tested to assure a good embedding in concrete having a contact area equal with 9 times the rebar cross section area, or a minimum diameter 3 times the rebar diameter.

These are suitable for fixing the PSA reinforcement coupler at the surface of the concrete units. PLASTIC NAILING PLATE KU-10 The nailing plates KU-10 (Figure 68 table 25) are used for fixing the PSA or PSAD reinforcement coupler with nails. The fixing flange ensures a minimal recess around the head of the PSA coupler. The recess is filled with fine concrete for protection against corrosion. Figure 68 Figure 69 Table 25 KU-10 Product no.

The anchor must be fastened to the reinforcement by suitable means so that it does not move during concreting. After stripping, unscrew. Figure 72 alterations reserved Mar-17 Page 29
STEEL MAGNETIC PLATE - TPM The plates with magnets TPM (Figure 73 - table 27 are used for fixing the PSA or PSAD reinforcement coupler to the steel formwork. The fixing flange ensures a minimal recess around the PSA coupler. When using this magnetic recess former it is very important that the surface of the formwork is clean.
