Description

The ReidBar™ Reinforcing Bar Connection System incorporates different solutions for connecting ReidBar™ reinforcing bars within concrete elements.

The system is for use as reinforcement bar mechanical connectors and anchors as specified in NZS 3101 for use with in-situ and pre-cast concrete structural elements.

The system includes ReidBar™ Grout Sleeves (including Ramset™ POZIFLO™ HS grout, Sika Grout 212 HP, and Fosroc Conbextra HS), ReidBar™ Threaded Inserts, ReidBar™ Flange Nuts (Steel), ReidBar™ Couplers (Steel), ReidBar™ continuously threaded reinforcement bars, and Ramset™ Epcon™ C8 Xtrem™ epoxy filler to make the connections.

Scope

1. The ReidBar™ Reinforcing Bar Connection System has been appraised for use as reinforcement bar mechanical connectors and anchors as specified in NZS 3101, for use with in-situ and precast concrete structural elements.

2. The following conditions and limitations apply to the ReidBar™ Reinforcing Bar Connection System:

• the reinforcing bars used in the threaded connections with the ReidBar™ Reinforcing Bar Connection System must be ReidBar™ Grade 500E continuously threaded reinforcing bars that meet the requirements of AS/NZS 4671; and,
• starter bars which are inserted and grouted with one of the specified grouts to the ReidBar™ Grout Sleeves can be generic bars of Grade 500E (in accordance with AS/NZS 4671) or ReidBar™ Reinforcing Bars and as specified in the Technical Literature; and,
• the final orientation of the ReidBar™ Grout Sleeve connectors in-service shall be vertical; and,
• the system must not be used where the in-service temperature may drop below –5°C; and,
• only ReidBar™ Flange Nuts (Steel) made of steel and ReidBar™ Threaded Couplers (Steel) made of steel may be used where connections may be subjected to high cycle fatigue. All other connectors covered by this Appraisal shall not be used when the system may be subjected to high cycle fatigue; and;
• concrete cover to the connectors must meet the minimum requirements of NZS 3101.1, Clause 3.11.3 and Table 3.6 as appropriate; and,
• the ReidBar™ Reinforcing Bar Connection System is subject to specific engineering design by a Chartered Professional Engineer and the installation of the system must be carried out by precast concrete manufacturers or building contractors under the guidance of a Chartered Professional Engineer; and,
• the ReidBar™ Reinforcing Bar Connection System must be designed and installed in accordance with the conditions and limitations of this Appraisal and the Technical Literature.
