Mechanical Splicing

The Bartek PTM Rebar Splice System is a parallel threaded mechanical splicing system for the connection of reinforcing bars from 12 to 40mm, it is designed and manufactured to meet or exceed the requirements of major international standards such as: AS 3600, AS 5100, ISO 15835, Eurocode2, BS 8110, DIN 1045, ACI 318, IBC, AASHTO, ASME Sec III Div 2.

Why a Mechanical Splice?
Due to the growing technical challenges in construction industry, traditional methods for connecting rebar, such as lapping or welding, is no longer the first choice. More and more construction codes prefer mechanical splice because it provides better structural integrity while minimizing costs.

A lapped splice is dependent on the concrete quality for load transfer so any degradation of the concrete will significantly affect the performance of the splice. With mechanical splices, the load transfer is conducted by the mechanical coupler so it’s independent of the concrete for the load transfer, which greatly increases the integrity of the structure.

Additional Advantages

• No reduction of rebar cross sectional area, full rebar strength maintained.
• Standard ISO Parallel Metric thread with great compatibility for connection with other systems.
• One standard coupler suitable for most splicing requirements.
• The state of the art Machinery we have developed ensures the thread made on the rebar is the same high quality as the couplers we supply.

Performance

• The splice works just like a continuous piece of rebar.
• Offers greater strength than lapping with better reliability.
• Provides full ductility independent of concrete conditions.

Design & Planning

• Greater flexibility in design preferred by the designers.
• Rebar congestion reduced and steel-to concrete ratio improved.
• More efficient design results in smaller and stronger structure.

Economical

• No more lapping lengths needed, rebar waste minimized.
• Easy and quick installation accelerate the construction with improved efficiency.
• Less experienced labor required and labor costs reduced.

Applications

Thanks to the nature of the permanent interlock from the crimping process, the BP rebar splice system is designed and manufactured in accordance with most of the popular standards such as AS 3600, AS 5100, ISO 15835, Eurocode2, BS 8110, DIN 1045, ACI 318, IBC, AASHTO, ASME Sec III Div 2. etc. and suitable for use in stadiums, bridges, dams, power plants and high-rise buildings for normal and seismic loads.

The Bartek PTM Standard Coupler is the basic coupler in our forging and threading splice system and it’s suitable for both standard splices as well as position splices. A optional lock nut is available in case one/ or both of the bars are impossible to rotate.

Features

• Applicable for high strength rebar up to AS/ NZS 4671 Grade 500N/E.
• Easy and highly efficient for both preparing the splice and assembly at site.
• Accurate splice length control thanks to the precise coupler joint.
• Highly reliable and consistent performance thanks to our crimping tech and improved design of the couplers

The Bartek PTM Terminator provides a mechanical anchorage for the rebar in concrete. It replaces hooked bars as end anchorage and works better in congested areas as the lapping length is reduced.

Bartek PTM Terminator is hot forged with a bearing area 10 times the cross sectional area of the reinforcing bar. Thanks to Hot-Forging, it’s compact and light weight in comparison to traditional flat head type and easy for installation with its small neck diameter.
