Expansion Joint
Hercules Expansion Joint (EJ)
Hercules Engineering single element joints are used where a robust, water-tight expansion joint is required in highway bridges, parking stations, access ramps and a variety of other applications. Our Engineers are available at both design and construction stages to assist with the design and installation details of the joints.
Design Features
Types & Series: Single Element Series 13
The series 13 joints are fabricated from steel angles or blades and supplied in two main anchorage configurations depending on whether they are required for heavy or light traffic.

Suggested Specification
1. Deck joints shall be fabricated from steel to AS 3679 Grade 250 (steel angles or flat bar blades, closed loop anchor bars and seal slot retainer) Hex bar anchors, Wherever applicable, shall be to AS 1443 Gr. S1214.
2. Steel angles, where provided, shall be drilled with vent holes at 300 crs to provide venting of air and moisture during concreting to permit adequate compaction of concrete behind the joints.
3. Upturns shall be provided at the junctions between curbs (or barriers) and deck which are usually the lowest point of the joint and hence the most likely point of leakage.
4. Welding shall be carried out to AS 1554 and, prior to galvanizing, all weld splatter shall be removed and the steelwork shall be grit blasted (to AS 1627.4 Grit Blast Class 2.5).
5. Galvanizing shall be carried out to AS 1650 but with a minimum zinc mass of 700g per m (approximately 100m thickness) after which all dags shall be removed and the individual lengths straightened to a tolerance of ±5mm over the entire length.
6. f.Joints shall be provided in (typically) six (6) metre modules, with bolted and dowelled water-tight connections.
7. Elastomeric seal elements shall be continuously extruded from CHLOROPRENE rubber, and shall be supplied and fitted in one continuous length (without joins).
8.The joints shall be fully assembled in the shop to confirm correct manufacturing drawings.
9. Angle-nosing joints shall be installed with the top leg of the angle parallel to the grade.
10. Completed joints shall be warranted against anchorage failure or dislodgment of the seal element for a period of 5 years from installation.
Types & Series: HERCULES (Heavy-Duty) FINGER JOINTS - HFJ Series
Hercules Finger Joints have been developed to fill the need for a heavy-duty expansion joint with large movement capacity. This type of expansion joint has been adopted as standard design for large movement expansion joint by many design authorities and government agencies worldwide because of their low & easy maintenance features.
Design Features & Advantages
Material
Installation
Method 1 - Installed in Concrete block out [preferred for cast in situ deck]
Method 2 - Installed WITHOUT Concrete block out [preferred for precast deck]
Maintenance
If maintenance requires replacement of membrane of finger plates, this can easily be carried out by de-tensioning the hold-down rods followed by removing 4-5 segments of finger plates in one lane and allowing traffic to continue using other lanes without causing congestion.

HERCULES ARCHITECTURAL EXPANSION JOINT
Hercules range of expansion joint also meets the requirement of architects. This includes joints designed to solve difficult problems with multi-directional movements and water-proofing requirements. Hercules engineers are capable of providing custom designed joints using many different materials e.g. Stainless Steel, extruded aluminum sections, brass and bronze with different finishes to meet all architectural requirements. All Hercules expansion joint systems can be incorporated with materials to provide fire protection.

HERCULES SINGLE ELEMENT BOLTED ALUMINIUM JOINT
Hercules Expansion Joint 'Type HAJ' is an aluminum deck joint which provides a light weight alternative to the heavier available steel designs. They can be used for heavy traffic on bridges, parking stations, access ramps and a variety of other applications.
Main Design Features
Austroads Clause 4.14 recommends a maximum gap of 100mm at the ultimate limit state. This is considered to be the maximum gap for providing a smooth and quiet ride. We propose that the joint be installed at time of maximum expansion to minimize the initial gap of the expansion joint.
