How To Anchor Pallet Racks To Concrete

What are Wedge Anchors?

To anchor pallet racking to concrete flooring, you volition need wedge anchors. Wedge anchors are steel bolts that are installed in pre-drilled holes to secure pallet racking frames (uprights) to concrete flooring.  At face value, the wedge anchors expect similar your typical commodities-nut-washer gear up. However, what makes wedge anchors unique are their tapered ends.

When the bolt is in the concrete, information technology is and then tightened, which causes the threads of the bolt to move upward through the nut. The tapered terminate is then forced through a metal sleeve (otherwise known equally an expansion clip). This increases the space the wedge anchor is taking up inside of the concrete and thus secures information technology in identify. Similar to how a drywall anchor works!

Wedge anchors come in a variety of unlike lengths and diameters. The larger the diameter, the longer the wedge anchor is, and thus the stronger it is.

Information technology is very important to consult a professional engineer to empathise what size wedge anchor is required to ballast pallet racking on a detail organisation.

The well-nigh mutual wedge anchor sizes are:

• 1/four" x two i/four"
• i/2" x 4-1/2"
• 3/8" 10 3"
• v/viii" 10 iv-1/2"

When to utilise Wedge Anchors

Installed will anchor pallet racking later on the uprights and horizontal beams accept been assembled, and are in the right place. A warehouse layout or a drawing is very of import in this step to ensure that the pallet racking organization is installed correctly.

Once the frames are anchored, the wedge cannot exist removed from the concrete. If the racks needed to be moved, the wedge anchor would need to be cut. Therefore, anchoring is one of the terminal steps in the installation process of a selective pallet racking project.

Anchoring after the uprights and horizontals are in place provides a safety internet in example a measurement was slightly off.

Like any construction project, careful planning and preparation beforehand will benefit yous in the long run. It is paramount that you, or your pallet racking installation team, have the expertise and equipment to go the job done correctly, efficiently, and safely.

How to Anchor Pallet Racking to Concrete Flooring:

1. Ensure y'all accept the following equipment

• Level
• Shims
• Hammer Drill
• Concrete Drilling Bit
• Vacuum/shop-vac/wire brush (for cleaning the hole)
• Wedge Anchors
• Hammer
• Impact Commuter with a properly sized socket for your anchors (a socket wrench could besides piece of work)

two. Level your Frames

It is common that warehouse concrete floors are not perfectly level. In this case, you can utilize shims (typically they are steel, or plastic) to get your uprights in a level position. If you fail to level your uprights, this will greatly bear upon the integrity of your racking system.

One time y'all have ensured that your frame is level, you are prepare to drill!

3. Drill Hole

There are typically two to three holes on each base plate, only in nigh cases, you will but need ane ballast per vertical post (so two anchors total per frame). If this is the instance, stagger the anchors so that you are not using the identical pigsty on each base plate of the frame.

At that place are instances where two or more wedge anchors are required per base plate. This is common for pallet racking that volition be storing a large corporeality of weight, or if the pallet racking is in a location where seismic activity is common. Consult your engineer or prophylactic officeholder to know how many wedge anchors are required for your pallet racking.

Drill through the baseplate hole of the upright using a drill bit of the aforementioned size equally your wedge anchors. The hole should go deeper than the length of your wedge ballast – see table below. However, it is all-time to consult a professional engineer to know the correct hole-depth required.

Once you are sure of the correct hole-depth, you can set a depth gauge on your hammer drill, or use the historic period-erstwhile fob of taping the bit.

The depth of the hole that y'all must drill will be based on the wedge ballast bore.

3/8"	2"
1/2"	2-5/8"
v/8"	3-3/four"
3/4"	4"

*These depths are but a proposition, it is best to consult an engineer to get the most accurate hole-depth required.

four. Clear Hole

Using a vacuum and/or wire brush, give the hole a cleaning. Clearing the hole will allow the anchor to grip the concrete ameliorate.

5. Insert Anchor

Slide a washer onto the anchor, and thread the nut so that it is flush with the top of the bolt. Adjacent, place the wedge ballast into the hole you lot have drilled. Using your hammer, drive it down until the nut connects with the base plate.

vi. Tighten Nut

Using an touch driver, or a socket wrench, tighten the nut. You lot will want to tighten information technology the best you lot tin can, but be careful non to over torque it (see torque value chart below).  You will see the ballast pull upwards every bit the nut tightens.

3/viii"	25
1/ii"	40
5/8"	60
3/four"	110

And there you have it – you lot tin can ballast pallet racking to concrete floor!

Why Anchor Pallet Racking?

Information technology is very important to anchor pallet racking to the warehouse floor to ensure the maximum stability and security of the system.  When installed properly, storage systems are designed to withstand unexpected forces like earthquakes and (more normally experienced) accidents caused by forklifts.

Anchoring your pallet racking will ensure that when these inevitable events occur, your pallet rack will remain secure. Should your upright frames shift after an effect similar a forklift accident, this could cause a arrangement collapse.

When pallet racking is anchored properly, a forklift blow may still cause damage to the organization, just will seldom cause a catastrophe like a full system failure.
