TEKMETSAN supplies a detailed Anchor Bolt Plan with every metal building system. These plans show the building dimensions, the precise locations for anchor bolt placement, and the total number of foundation anchor bolts required in the structure.
Anchor bolts are not just the connection elements between the steel and concrete surfaces but they are one of the most important element in a steel structure. Anchor bolts are responsible for the transfer of loads between the steel and concrete member.
Depending on when the anchors are installed, anchors used by Tekmetsan are classified into two categories;
These are the type of anchor bolts that are installed in place before pouring the concrete and are efficient in handling forces of high magnitude. Bolts are firmly held in place while the concrete is poured to maintain proper alignment and position.
The size and location of the anchors can be determined from construction drawings.
In the below figure, you can see some examples of cast-in anchors.
Good installation is critical to performance. Here is the 5-step for the installation.
1. DRILLING: Drill correct hole size and depth on concrete/brick/stone/masonry.
2. HOLE CLEANING: Blow out dust and clean the hole with brush, then blow out remaining dust.
3. INJECTING: Inject mixed adhesive from the bottom of the hole.
4. INSERTING: Insert and rotate stud/bolt/anchor/rebar/threaded rods into the hole.
5. HARDENING AND CURING: Time table refer to TDS. Don’t touch until full curing.
• All structural columns on a building must be anchored by at least four anchor bolts
• The placement of all actor bolts on the structure must adhere to the approved Engineered Foundation Plan
• All anchor rods shall be placed with their longitudinal axis at a 90-degree angle to the surface of the foundation
• A template (preferably steel) must be used to insure exact placement of anchor bolts in concrete.
