Installing Bike Bollards using Anchor Castings

Home > How to Install Commercial Bicycle Racks and Bike Bollards > Installing Bike Bollards using Anchor Castings

Bike bollards are reliable bicycle storage devices that minimize the obstruction that results from improper bike parking on railings and outdoor site furnishings. Their sleek, contemporary designs complement surrounding architecture and landscapes. By placing an anchor casting in the concrete’s substrate while pouring new concrete, a bike bollard can be installed with a threaded rod. It is important to note that with this installation method, the bike bollard offers little impact resistance.

Before installation

Study the site plans
Site plans are generally created by the architect of the project. The architect will mark the intended location of each bollard on the plan. Ensure that the plan coincides with the site and familiarize yourself with the intended arrangement of the bollards.

Check for hazards
Always check for hazards such as water pipes, gas lines, and underground wiring before digging.

Prepare the site for concrete
Please consult your local Building Code Department to determine the recommended digging depth below the frost line in your area. The new concrete footing must reach this recommended digging depth.

Note: If the frost line is less than 12″ below surface level, dig to a minimum depth of 12″. This is recommended in order to create stability.

The diameter of the hole differs based on the bike bollard model. Refer to product drawings to determine specific measurements.

Center the auger on the installation mark and bore a hole to the required depth and diameter.

Ensure the area is properly formed to create a perimeter that will hold wet concrete.

Use a dirt tamper to compact the soil below the intended surface.

Prepare the anchor casting for designated location
If the surrounding area is quite dirty or dusty, cover the bottom hole of the anchor casting with duct tape to prevent debris from entering the threaded area. The top hole should already be covered with the plug (A).

Place the anchor casting in designated location and ensure that the top of the casting will be flush with the finished surface of the concrete grade (the anchor casting is 4″ high).

The top of the anchor casting must be level.

Pour The Concrete

Mix and pour the concrete
Ensure that the proper ratio of water and concrete mix is used—the concrete should have a similar texture to moldable clay.

Pour the concrete evenly, ensuring surface is level, and avoid disrupting the anchor casting.

Allow the concrete to cure
A minimum of 2–3 days should be given for concrete to cure before beginning construction projects on new concrete surfaces.

Note: Moisture in the environment and cool temperatures can significantly slow the process

Secure the bike bollard

Place the bike bollard near the anchor casting
Keep the bike bollard in its protective packaging. After ensuring the concrete surface has fully cured, carefully place the bike bollard beside each anchor casting.

When ready to install, remove the bike bollard’s protective packaging.

Remove the plug (A) from the top hole of the anchor casting.

Set the bike bollard over the anchor casting
Set the bike bollard base upright and maneuver it so the center lines up with the threaded hole in the anchor casting.

Lower the threaded rod and tighten
Lower the threaded rod through the bollard base.

Continue to thread the rod into the anchor casting.

Tighten(1) the threaded rod by hand until it is secure in the anchor casting.

Secure the bike bollard
Place the washer over the threaded rod so that it rests on top of the shaft of the bike bollard.

Apply the 1″ nut to the threaded rod and use a wrench to tighten until the bike bollard is secure.

Note: Be sure to check the orientation of the bike bollard arms before securing the bike bollard.

Secure the bike bollard cap
Remove bike bollard cap from its packaging.

Place the cap on the top of the shaft of the bike bollard.

Secure and align the cap to the bike bollard base with the three set screws. Tighten in equal amounts to ensure that the cap remains centered.

Place the plastic plugs (B) over the set screws.

Inspect the installation
From a distance, examine the plane of view.

Ensure the bike bollard is plumb to the surface, and the surface is flat.

Check the bike bollard for any signs of surface damage
Abrasions should be covered as soon as possible to prevent rust and ensure the proper life of the bike bollard. For damage repair or other servicing needs, please contact Reliance Foundry’s sales department.

Care and maintenance

Reliance Foundry manufactures its products to the highest design standards to ensure their durability. Reliance Foundry’s bollards are finished with long-lasting powder coating. In most North American environments, routine inspections and cleaning will ensure that bollards retain their aesthetic appeal. Proper care and maintenance are required to maintain the finish and ensure a full service life.

1. Recommended tightness is until the threaded rod reaches a depth of approximately 1″ in the anchor casting
