What Is An Anchor Bolts?
Anchor bolts are cylindrical fasteners that connect objects and structural elements to concrete. They come in various styles and are made by multiple manufacturers.
They are commonly used in new construction where the location of walls and elements that need to be connected to the foundation is known and for retrofitting tasks. They can be purchased at hardware stores, construction supply companies and manufacturers. When installed correctly they create a sturdy and long-lasting connection.
Anchor bolts are used to connect structural and non-structural elements to concrete, transferring tension forces and shear forces along the way. For example, steel columns can be connected to a reinforced concrete foundation using anchor bolts, while a facade system can be attached to a reinforced concrete wall with fasteners or steel plates.
Stiffeners may also be used as an alternative connection component for both structural and non-structural elements alike in order to create a strong and reliable attachment between them.
Types Of Anchor Bolts
An anchor bolt, also known as a fastener, is an essential part of many construction projects. There are many different types of anchor bolts available to choose from based on the purpose of the project and the desired results.
Anchor bolts are categorized into two groups for industrial projects based on their installation requirements: Cast-in-Place and Post-Installed.
Cast-in-Place anchor bolts are cast directly into the concrete and become fully secured when the concrete cures and hardens. They can be further categorized into various types such as Drop-in, Bent-bar, Plate, Sleeve, Headed, and Swedge.
Post-Installed anchor bolts are installed after the concrete has been laid and require a hole to be bored into the surface. Common types of Post-Installed anchor bolts include Lag Screw, Hammer Driver Pin, Toggle Wing, Double Expansion Shield, and Wedge.
Applications Of Anchor Bolts
Anchor bolts are essential in construction projects, as they provide a secure connection between two components. They are used to hold down anything from metal frames to concrete foundations.
Anchor bolts are commonly used in various industries to secure and attach elements to concrete. They have a wide range of applications, including in the chemical and petrochemical industries for fixing equipment and structural members, the power and steel industry, building services, hospitals for installing equipment, railways and aviation, manufacturing plants, pipeline industries, pharmaceutical and food processing plants, and nuclear industries.
Advantages Of Using Anchor Bolts
Anchor bolts are a great choice for many different construction projects. They offer several advantages compared to other types of fasteners. Anchor bolts have higher load capacities, which make them ideal for use in heavier structures where more weight needs to be supported.
Furthermore, they are generally easier to install than screws and other types of fasteners, making them a cost-effective choice.
It’s also easy to adjust the tension on anchor bolts if needed, so they can adapt to changes in their environment over time. Overall, anchor bolts are an excellent choice for heavy-duty applications and provide benefits that no other type of fastener can match.
Considerations When Deciding Anchor Bolts For The Job
The design and configuration of anchor bolts involves the bolt passing through the fixture, with the length of the bolt protruding depending on the frequency of tightening and the placement of the nut in the concrete.
To achieve a polished appearance, using a uniform-headed anchor bolt or smooth-headed sleeve anchors can be used. Other options such as female anchors, machine screw anchors, and drop-in anchors can also provide a consistent look.
It is important to note that the bolt is the weakest link in the structure, thus it is crucial to determine the appropriate diameter of the anchor bolt based on the weight of the load being supported. Larger diameter, more deeply set anchor bolts are best for heavy loads attached to concrete.
