INTRODUCTION The Patent System coupler is a durable connection of reinforcement. The traditional way to connect reinforcement steel was to

overlap and weld the reinforcement together. The Patent System reinforcement coupler is a simple and efficient method to

connect the reinforcement steel which eliminates the disadvantages of the traditional procedure. The Patent System couplers

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 Patent 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 Patent System couplers are delivered standard galvanized.

- There is variant in which the pressing coupler is made of stainless steel.

The patent system reinforcement couplers are composed of reinforcement steel B500B 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.

The reinforcement coupler PSA (Figure 10 – table 1) is composed of a reinforcement steel and a sleeve PKB (table 2) with

interior metric thread pressed at one end. In connection with a reinforcement coupler TSE the coupler PSA ensures an

uninterrupted reinforcement for all types of precast concrete units. These couplers can be made at different dimensions as

shown in the table 2.

These reinforcement couplers can also be used to lift and move the precast concrete elements.

The PKB couplers are made of steel 20CrMo5 or equivalent, electrolytic galvanized. These couplers are marked with the

company logo and the thread type. The reinforcement steel is made of B500B EN 10080.

On request the PKB couplers can be produced of stainless steel or 20CrMo5 hot zinc coating.

The PSAG coupler, generally have the bend diameter DB= 10 x d, but this can be produced on request with DB= 15 x d or DB=

20 x d. Also other length LA and LB available on request: PSAG d x Length LA/ LB in mm. For choosing dimensions LA and LB

should take into account the minimum size according with the table 10. LA 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:

DBmin = 4 x d for bar diameter d ≤ 16mm

DBmin = 7 x d for bar diameter d > 16mm

L = LA + LB +LA – 2x for double bend

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 End Coupler it is highlighted by the next advantages:

Minimize the length of the rebar and reduce the

congestion inside the concrete element;

Eliminate the hooks;

Faster and simple installation;

Simplifies the structural design;

Better anchorage in the concrete element.

The traditional method consists in a hooked rebar anchorage

who comes with a series of disadvantages:

Requires longer lengths of anchorage which

increase rebar congestion;

More labor for the installation;

Longer time for execution;

Hidden costs, especially for bigger diameters (the

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.

PKB-W THREAD WELDABLE COUPLER

PKB-W – is a PKB bush used to connect reinforcing bars to structural steel plates or sections. The PKB-W bush has a thread at one end. The other end is welded directly to the structural steel. The PKB-W couplers are made of steel S355 or equivalent. The type and size of weld must be determined by the designer. Welders should be qualified for the type of weld required.

TWSK POSITION COUPLER

TWSK position couplers can be used in combination with the Terwa Patent System couplers, and are available for steel reinforcement bars with diameters ranging from 10 to 40 mm. It is a perfect solution for connecting two rebars when it is not possible to rotate one or both of the bars. They also provide a solution for the connection between the steel reinforcement carcass of the monolith and precast concrete elements. A TWSK position coupler consists of a threaded bolt (SK), two nuts to secure the system, and a threaded bush (BK). The couplers have CE marking, are being tested for certification, and are manufactured in accordance with technical standards.

INSTRUCTIONS FOR INSTALLING PATENT SYSTEM COUPLERS

Place in and rotated the threaded PSC BOLT onto the PSA coupler already embedded in concrete.

Figure 56

Screw the threaded PSC bolt using an allen key.

Figure 57

Use a special torque wrench made by TERWA to tighten the connection. The necessary torque for each type of rebar is shown in the table below.

Figure 58

Place and rotate by hands the second PSA coupler until the couplers are fastened.

Figure 59

The connection is finished by using a special torque wrench made by TERWA to tighten the connection. The connection must be sufficiently tight to prevent movement during concrete placement. The necessary torque for each type of rebar is shown in table 21.

The nailing plates KU-02 (Figure 66, table 24) are used for fixing the PSA or PSAD reinforcement coupler to the formwork with nails. 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.

The plastic nailing plates KU-02 and KU-10 are nailed to formwork (Figure 72). Using forming wax on the nailing plate makes it

easier to remove and screw on anchor or fixing insert. The anchor must be fastened to the reinforcement by suitable means so

that it does not move during concreting. After stripping, unscrew.

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. The recess is filled with fine concrete for protection against corrosion.
