It is easy to learn how to install anchor bolts for concrete. There are only two things to know, the first is the requirements for the anchor bolts and the second is how concrete cures. Then, installing these bolts in the concrete is easy.
These specifications are easy to find. Architectural drawings and plans will define the requirements of the bolts and the placements. These will detail the size and strength of each set of bolts. The manufactures requirements for machinery installation will indicate all the details including a diagram of the placement, size and depth of this anchor.
Once these bolts are in place, concrete is poured around the bolts. It takes about four hours for concrete to set; concrete reaches 75% of its compression strength in seven days and takes 28 days to reach 90%. During this time any pressure on the bolts can loosen them. These bolts will need to hold objects in place when these objects are pushed, pulled or twisted and need all the strength that concrete can give them. During construction these times should be built in to the plans and allow adequate time for the concrete to cure to the desired strength.
Concrete cures best when the temperatures stay between 40° and 90°. Concrete must be kept moist, especially new pours. Concrete is self heating and this dampness dissipates the heat allowing a strong cure and keeps the top layer in excellent condition.
Attaching concrete anchor bolts in to a concrete floor at a later time can be done. The process is more complicated and has more opportunities for weaknesses. This process involves drilling a hole large enough for a bolt, filling it with a material that will harden, placing the bolt into place and allowing this to set in place.
These special bolts set in concrete are just another step in the construction process and easy to do.
