Setting Anchor Bolts


Being a steel erector each day can have its pros and cons. For the most part, each erector experiences many of the same issues over and over again. One of those issues is setting the low anchor bolts correctly. Here is some information about setting low anchor bolts the correct and incorrect way.

There are many steel erectors each day constructing very similar structures. Those structures usually have problems that occur with many other projects the steel erector is working on. One of the problems that continually occurs is setting the anchor bolts.

These bolts can sometimes be tricky to deal with. Many times these bolts are set with their tops lower than the elevation they are supposed to be set at. Or the top of the bolt can extend the base plate and not allow full thread for the nut. This can certainly make it difficult, but as you gain more experience you will become better at dealing with these types of bolts.

When the anchor bolt is set low, many steel erectors call that, "short anchor bolts." The best way of resolving it is by making the bolt longer. Now, you might ask, "how do I make it longer?" Well, the best way of extending the bolt is to thread couplers and weld extensions to the bolt.

Remember that anytime you are doing a correction you do need to consult with the structural designer. Consulting with the designer will help you make sure everything is done according to the designer's special procedures so it is advised that you do consult the structural engineer.

Putting Anchor Bolts in Concrete


Anchor bolts are items that are used to attach objects to concrete. They come in a variety of shapes and forms, usually having emblems or designs on them that are unique to the company which creates them. Regardless of their appearances, however, they all have this same similarity: every bolt has a "threaded end" to which a washer or nut can be added. Anchor bolts are used for a variety of things, such as attached wooden frames to walls, constructing buildings, transferring loads from a wall to the top of a roof, anchoring shear walls and paneling of walls, tying down devices and holding some of them in place, holding beams in position for walls or large structures (e.g., dams and skyscrapers), et al. Thus, anchor bolts probably are taken for granted by the average human; nonetheless, though, they are objects that individuals need for many structures.

The most common, strongest, and simplest form of an anchor bolt is the "cast-in-place" anchor. It has a standard bolt with a hexagonal head- the head is placed into the damp concrete before setting it. Cast-in-place anchors are used for heavy machines on concrete surfaces, as they tend to be somewhat difficult to cast with. Another design of an anchor screw is the bent hood with a sharp hook at the very tip design; this design is not nearly as common or simple as the cast-in-place design, though. Nevertheless, they are both used and for different reasons.

After the concrete has been fixed, there are other types of bolts that may be used: epoxy bolts and mechanical bolts. Epoxy bolts are the most powerful type of bolts, but they are somewhat difficult to install, since it has to be put into the very exact position, the hole has to be ridiculously clean, and the set time has to be monitored vigilantly. If an individual does not use an epoxy bolt with caution, disaster may arise.

Concrete Anchor Bolts


When constructing a building, anchor bolts are needed to attach object to concrete wall or base in order for the foundation to be stronger and more durable. With concrete anchor bolts, the structure is resistant to earthquakes and other phenomenon that may rock it. Concrete anchor bolts are the most sought-after bolts and it comes in different types for different purposes.

Types of concrete bolts include wedge bolts, best for interior applications; galvanized wedge bolts, which offer the best corrosion resistance; sleeve bolts, which are heavy duty anchors for use in brick, stone, concrete or block; strike bolts are best for solid concrete designed for medium to heavy loads; lag shield bolts are recommended for use in medium and heavy loads holding both dead weight and vibrating loads to be anchored in concrete, brick, block, and stone; leadwood screw anchors are used for removal of fixtures without loss of holding values; double expansion anchors are best for anchoring into brick, concrete or block base material; hurricane shutter anchors comes with hurricane shutter insert anchors to promote good fastening performance while split drive anchor bolts are good for light to medium duty in concrete.

These little anchors play a vital role in large and gigantic structures from industrial buildings to plants obtain solid foundation. These and more of your construction needs can be bought in any hardware stores near you. If you want the convenience in buying bolts, you can also purchase them online for fast and easy buying. Good luck!

Building Foundation Anchor Bolt Problems For Builders


For those of you who don't know what an anchor bolt is, it's usually an L shaped bolt that goes into the concrete and is used to connect the bottom framing plates to the concrete slab, footing or building foundation. But here are some of the things that you might not know about your building foundation and metal bolts and how they can work more efficiently together.

Did you know that there are different lengths of anchor bolts? Do you know that there are different sizes of foundation bolts, for instance I've seen foundation bolts as small as 3/8 of an inch and as large as three quarters of an inch. It's hard to imagine that we need so many different types of L bolts for our building foundation.

Now here's something that even some builders have a problem with. It's not a big problem, but I've seen contractors argue with structural engineers about which types of anchor bolts are actually going to be required for one particular project. Now remember, most builders don't have the knowledge or the responsibility a structural engineer might have, about building foundation, especially if it ever failed.

The biggest problem with contractors and builders who think that they know more about building foundations and L bolts than the structural engineers or even the city engineers, should try to keep one thing in mind. They're not responsible for any structural problems that were assembled according to the building plans, but the structural engineers are.

The next time that you're looking at a set of blueprints and it calls out for a 7 inch minimum anchor bolt embedment, make sure that you purchase the right L bolt's for that particular job. I'm not writing this article, because I've never seen this happen, I'm writing this article, because I know someone who installed the wrong anchor bolts on one of their projects. These L bolts were later removed as the city building inspector requested a correction for the change.

The building inspector found the problem and the contractor got the education. Even though the contractor knew better, he still got the education.
