Innovative Shortcut For Precast Connections

1

Developer: Micron Technology
Client: JEKS Group
Product Supplied: Moment Grout Coupler

Project Description

Micron Technology’s new center of excellence for SSD Assembly and Test is located in Batu Kawan Industrial Park, Penang, Malaysia. This new facility development is located on a 52.6-acre site which represents an investment of US$356.6 million (RM1.5 billion) over five years.

The Problem: The conventional method of lapping long rebars according to Eurocode standards has caused inconveniences on site. Handling long lapped length of rebars protruding from precast beams and columns is very tedious. Not to mention that the long starter bars are very dangerous to be installed which has alarmed safety concern from the site management.

Long rebar lap length caused long installation time on site along with safety concern

The Solution

After understanding the pain points of our client, instead of using the conventional method which involves corrugated duct and long lapping of rebars, Halfen Moment proposed the solution of using Moment Grout Coupler to connect precast beams & columns.

With the application of Moment Grout Coupler, our client were able to reduce 60 to 70% of the rebar lapping length with this rebar coupler system, saving more rebars and also reduce the installation time. Moreover, when the long rebars length were reduced significantly, site safety factor has been improved as well.

Besides, the advantage of Moment Grout Coupler as a transitional coupler gave more flexibility to our client as the rebar sizes varies from level to level on site. Lastly, the rough surface of the coupler’s body managed to provide a strong bonding between the coupler and the concrete.

The Result

Our client was very happy with the quality of the supplied Moment Grout Coupler, especially when barbreak system was achieved when testing was conducted. Overall, the usage of Moment Grout Coupler has make our client’s life much easier, not only to the precasters but also the contractors from Micron’s project. Nonetheless, the time saving from connecting precast beams and columns, has improved our client’s productivity, with less workers needed.

Your Only Rebar Coupler For Precast Connections

Ideal Coupler For Precast Element Connections

The connections between precast elements are a safety critical component in modern day structural precast concrete construction. The success of this construction method goes beyond the structural performance of precast beams and columns; it also includes the performance of the connection. For the connection, the performance is not only limited to the structural robustness, but also embodies simplicity and productivity during the erection process. The connection types employed will not only affect the construction cost and speed but also have an impact on the sections that can be used via the ability for forces and moments to be redistributed throughout the finished structure.

Moment Grout Coupler, consists of a one piece design, is a mechanical splicing designed for connecting precast concrete. Compliant with ISO 15835, each grout coupler combines the benefits of the Moment JT threaded system and will achieve barbreak when used together with Moment’s proprietary 100MPa grout.*

Specifically for precast connections, Grout Coupler can be used for connecting precast elements (walls, columns, beams) either horizontally or vertically. The most popular connections used with Grout Coupler are:

  1. Column to foundation connections
  2. Column to column connections
  3. Beam to column connections

1. Column To Foundation Connections

For this type of connection, the high tensile steel starter bars are left protruding from the foundation. After that, a precast column with vertical sleeves at the end is placed over the starter bars. The sleeves are the filled in with grout to provide a connection. This connection has the ability to provide moment resistance at the connection between column end to footing. Additional technologies such as precast shoes can then be used to eliminate the need for propping.

2. Column To Column Connections

Similar to the above application, this enables the launching of one column section on top of another one whilst providing full moment continuity across the joint. This is specifically important on projects with large column sections as the height of the element is often limited to less than 1 storey because of crane capacity limits.

3. Beam To Column Connections

You can use grout couplers to overcome one of the biggest challenges in precast concrete construction; a moment resisting frame. In this application, you provide clearance holes through the precast column and use a grouted coupler to provide full continuity through the precast column.

Picture1

To broaden the field of application, two product types are available: Full Grout Coupler and Half Grout Coupler. The rebars used with a Full Grout Coupler require no bar end preparation, such as threading, and are simply inserted to meet at the nominal centre point of the coupler.

For more information on Moment Grout Coupler, please contact our offices where we can showcase you the actual Grout Coupler as well as our latest innovative precast accessories.

*Lower grout grades might be possible, but it depends on the rib profile of the individual rebar supplier.

The Bolted Coupler Which Does Not Require Rebar Preparation

   MBC Coupler
Developer: Oberoi Realty
Main Contractor: Samsung C&T Corporation
Product Supplied: Moment® Bolt Coupler (MBC)

Project Description

Oberoi 360 project is a mixed development located in the Worli, district of Mumbai, Commercial & High end Residential Hub of Mumbai, north of the central business district. The site, lying just 600 meters east of the Arabian Sea, is contextualized around the nearby water. As most of the surrounding buildings are low-rise, the tower’s western facing sightlines are maximized to offer views of the sea.

The Requirement : Rebars protruding from the foundation piles were too short to allow traditional lapped splice.

MBC Application
A nut runner is always recommended to tighten the bolts for higher precision and faster installation.

The Solution

The best solution for the continuity of bars protruding from the foundation piles is using the Moment Bolt Coupler (MBC). As the bar end does not need to be prepared in advance, MBC coupler is a flexible solution for contractors. It only requires a wrench or a nut runner  to tighten the bolts along its serrated hollow body. Hence, it is easy to operate even in a confined area at site.  The installation is very straight forward with simple demonstration and guidance.

The Result

Halfen Moment India supplies a significant amount of MBC coupler to this mixed development project , which proves that MBC coupler is the ideal and cost effective coupler for remedial and repair works, particularly when one bar is already fixed in the concrete. The team of Samsung & Oberoi appreciate the convenience of this coupler as it managed to save more time and were able to execute the work well in advance.

MBC Application
Using MBC coupler is a cost effective method of joining reinforcing bars, particularly when the fixed bar is already in place.

How To Connect ‘Mistakenly Shortened Rebars’ At Site?

There are 2 common methods to connect reinforcement bars.

The traditional way of connecting rebar is by overlapping 2 rebars, with typical lap lengths of between 30 and 50 times the diameter of the rebar in accordance with EN1992-1-1.

The modern way of connecting rebars is by using a mechanical splice system; a mechanical connection between two pieces of rebar that enable the bars to behave in a manner similar to continuous length of rebar. Most mechanical splices join rebar end-to-end along with the rebar threads, providing many of the advantages of a continuous piece of rebar, which is more reliable. Read more: Mechanical Splices VS Lap Splicing

MBC- The Ideal Coupler for Remedial & Repair Works


If the rebar lap length was shortened by mistake, we will not be able to connect both rebars if:
1) The lap length is less than that specified for a particular application.
2)  There is no way we can thread on either side of the rebars at site/ the rebars are being planted vertically

Like any other engineering problem, this situation may have other solutions like welding, drilling in additional rebar, depending on the site conditions, codes, materials used and the structure that is going to rest on this foundation.

However, the best way to connect this is the Moment Bolt Coupler (MBC), a bolted coupler which does not require any rebar preparation, designed for the connection of two rebars which haven’t been previously threaded.

Each MBC coupler features a serrated hollow body which will grip the rebar. A number of bolts along one side will press the bar against the serrations and lock both bar ends and complete the connection.

Bolts Designed to Shear Off at a Specified Torque


MBC coupler is a cost effective method of joining reinforcing bars, particularly when the fixed bar is already in place and there is insufficient space for a hydraulic swaging press. Below are the benefits of MBC coupler.

• No threading required. Installation can be done by using a wrench.
• Bar ends are supported within the coupler by reversed teeth on the internal wall, and as the lock shear bolts are tightened, the conical ends embed themselves into the bar and press the bar on to the teeth.
• Excellent for remedial & repair works where one bar is already fixed in concrete.
• Capacity load higher than 108% characteristic yield strength of grade 500 reinforcing bar.
MBC Bolted Rebar Coupler
Nut runner is strongly recommended to tighten the bolts for higher precision and faster installation.
