Anchor Bolts

An anchor bolt is a mechanical fastener that fixes one or more objects to a concrete surface. They are heavy-duty fasteners and are widely used by civil engineers. In photovoltaic mounts, they are often used in concrete projects on flat roofs and floors. The unique design of anchor bolts keeps solar mounted structures stable and in place. In this article, we will explore the different types of anchor bolts.

 Types of Anchor Bolts 

Depending on the installation requirements, Anchor bolts used in industrial projects are categorized into the following two groups:

1. Cast-in-Place Anchor Bolt 

2. Post-Installed anchor bolts 

From the name itself, it is quite clear that the cast-in-place anchor bolts are cast directly into the concrete material. They are the simplest but the strongest of all anchor bolts used. This type of anchor bolt is placed in the wet concrete that becomes fully secured when the concrete cures and hardens.

Anchor bolts of cast-in-place types are again categorized into various groups. The most common types of cast-in-place anchor bolts are:

Drop-in Anchor Bolts 

Bent-bar anchor bolts (J-bolts or L-Bolts) 

Plate Bolts 

Sleeve Anchor Bolts

Headed Anchor Bolts 

Post-installed anchor bolts are installed after the concrete has already been laid down at the site. In this type of anchor bolt, a hole is required to be bored into that concrete surface and the screw is installed.

Some common post-installed anchor bolts are as follows:

Lag Screw 

Hammer Drive Pin 

Toggle Wing 

Expansion Anchors 

Wedge Anchor 

Expansion Anchors 

Application of Anchor Bolts in Solar Mounting System

In Conclusion 

Most anchor bolts can be classified as either cast-in-place or post-installed. There isn’t a one-size-fits-all application for concrete anchor bolts.
