Why are pallet racking anchors critical to the entire structure?

Pallet racking anchors are mechanical fasteners used to attach a racking system to a building. Their purpose is to hold the pallet racking in place and resist continuous counter forces such as: earthquakes, wind and tipping forces caused by narrow/high racking, accidental impact forces at the bottom of the columns (i.e. from forklifts) and shear forces (horizontal reaction forces) ) reducing the restraining capacity of the racking.

If the anchors are unable to withstand these attack forces, the consequences can lead to significant bending forces on the columns, affecting the overall stability of the system and, in the worst case scenario, leading to collapse. To avoid this, it is critical to select the correct type of anchor for the different conditions and types of racks in the facility.

What common types of pallet rack anchors can be found in warehouses?

Wedge anchors are a popular type of anchor made of carbon steel, hot-dip galvanized, stainless steel or galvanized steel. These fasteners are primarily used for solid concrete and cannot be removed if you decide to rearrange your pallet racking, as doing so would damage your floor. Concrete impact anchors are anchors in the form of impact expansion and are also used in solid concrete; given their mechanical properties, they should not be installed in any other type of masonry material.

Screw anchors are a less common type of fastener found in warehouses. They are used for temporary or permanent anchoring, since they can be removed and can be installed in concrete and masonry.

Finally, we have sleeve anchors that are perfect for light to medium anchoring in concrete and masonry. Whichever type of anchor you choose, you will find a variety of diameters, lengths and thread lengths.

What size pallet rack anchor is appropriate?

A rule of thumb is that the wider the diameter and the deeper the embedment, the stronger the anchor will be. Therefore, it is important to check local building codes or have an engineer determine the bolt size given that several factors need to be considered: the size of the hole in the base plate of the column, seismic activity, and the area where the anchor is to be used. In addition, the thickness of the floor material, the mechanical properties of the floor material and the flatness of the floor should also be considered in case shims are needed.

How many anchors should a post base carry?

The ANSI/RMI standard states that all rack columns should be anchored using at least one anchor per column. Depending on the type of anchor, two anchors may be installed to prevent the column from rotating upon impact. In the event that the user is unable to properly secure the rack, it is recommended to work with the rack manufacturer’s engineers to verify alternative methods of securing the system while ensuring the structure is safe for use.

Should I tighten a loose anchor?

Bolts and anchors must be properly tightened to the minimum recommended torque specified by the manufacturer. 3/8'’ anchors are typically 40 foot pounds. Under-tightening will cause the anchors to fail.

The Diagonal Bracing Function when Lifting Ringlock Scaffolding

Things must be taken into account:

The straps generally fit in a bay from the bottom to the top without any interruption. This reinforcement pattern is repeated every fifth section. Alternatively, the keys can start in the lower outer bay. And it can also continue as a straight line until it reaches the outer end of the Ringlock scaffolding. Then, the bracing is repeated in this way from the next previous lift until it reaches the top of the Ringlock Scaffolding. For very long scaffolding pipes, it is preferable to start shoring at both ends and work towards the center of the facade.

1. Offer the wedge frame at the other end of the clamp to the spindle of the Ringlock scaffolding standard on the next overhead lift. Sliding the wedge frame on the Spigot on the Base Collar and insert the Clamp Wedge to attach the clamp. Always work from a fixed node to a mobile top node.

2. The diagonal / frontal bracing should be fixed at least in each fifth bay along the Ringlock scaffolding and from the bottom to the top of the Ringlock scaffolding, or as required by the design.

3. Diagonal bracing helps to harden the Ringlock scaffold and ensures that it is square, keeping the Ringlock scaffolding standards aligned vertically.

Work at heights

Work at height is inevitable in most formwork activities, and special safeguards will be implemented to avoid accidents when falling from height. All criteria must be verified and all requirements met as in the Code of Practice for Working with Height Safety [Ref. 8].

The fall prevention plan must be carried out by the occupant of the workplace.

Construction of safe formwork related to design

Safety aspects should be considered and controls should be implemented at each stage of the life cycle of the formwork structure, including planning and inspection, and during construction. Some common measures for good construction practice to ensure a safe formwork design, in addition to those already mentioned, are the following:

- Provide adequate shoring or re-shoring

- Avoid using an accessory directly on top of another accessory

- Ensure that suitable temporary reinforcements are placed while the formwork is configured

- Ensure that the anchoring of the system formwork can be determined visually

- Ensure adequate provision of lateral pressure on the forms

- Control the lateral pressure in the forms by means of the vertical speed of placement by means of settlement, type of vibration, additives, etc.

- Regulate the horizontal sequence and the speed of concrete placement to avoid unbalanced loads in the formwork structure

- Control any load that may cause vibration and shock

- Prevent premature removal of media

All of our premium scaffold components manufactured by Technocraft Industries are hot-dip galvanized and manufactured from the highest quality steel resulting in optimum durability and a faultless safety rating. Each product is rigorously tested to ensure all OSHA standards are met or exceeded.
