Concrete Anchor Bolts
Concrete anchor bolts are fasteners that are sturdy and are therefore used in many construction projects, such as the attachment of wood frames to concrete structures, wall paneling, anchoring shear walls and other such heavy duty construction projects. These bolts usually have threaded ends so that a washer or nut can be put at the end to attach the wall forms and other parts securely to a slab foundation made of concrete. The materials needed as well as the process of casting concrete anchor bolts are explained below.
First, make sure the concrete forms are ready before you install the concrete anchor bolts. These forms will be either steel plates or wooden boards that will hold the concrete together while it hardens and cures over a week's time.
Then get a pencil and a measuring tape and mark the positions of where you want the concrete anchor bolts to go in the concrete forms. This mark will be your guide to placing the anchor bolts' holders. It is important that the position of the concrete anchor bolts, because once it has been placed in the concrete, and cured and dried, it is very difficult to move.
You can then put the anchor bolt holders on these marks and nail them into the concrete. This ensures that the anchor bolts themselves will be placed in the right position. The anchor bolt holders serve another purpose, and that is to keep the threads found in the anchor bolts free from concrete splash and any other thread damage that can happen.
A wrench can be used to screw the concrete anchor bolts into their holders. Generally, anchor bolts have guide marks that help you screw them in to the required height and depth, so if you follow these you can insert them properly. Next, pour the concrete into its form and allow it to flow onto and over the anchor bolts. Stop pouring the concrete once it reaches the proper level which should be indicated by your concrete form.
Now you can allow the concrete to dry and cure before you remove the holders of the anchor bolts. By doing it this way, you can ensure that the anchor bolts will not be moved when you remove the holders. The removal of the holders is quite easy; you simply have to unthread the cap on the concrete anchor bolts. Remember to wait for as long as you need to before doing this step, because the mix used in making your concrete will determine how long it takes to completely dry.
Most people are aware of what electricians do for a living, or at least we have a vague idea. But did you know that electricians are also required on oil rigs? Needless to say this is a very different job from the type you would do if you were working...
