Core advantages of j bolt anchor
j bolts for concrete have outstanding performance in pull-out resistance and adaptability to vibration environments due to their unique hook-shaped structural design
1. J bolt for concrete Super strong pull-out resistance (core advantage)
The J-shaped hook forms an “inverted” structure in the concrete, which is more difficult to pull out than the right-angle anchor of the L-shaped anchor bolt.
Suitable for scenes with extremely large vertical tension (such as the wind load pull-out force on the base of a wind turbine). No matter how it shakes, it will not loosen. The round hook design has its own anti-loosening function. Machines such as tower cranes and large motors that shake every day need it the most
Under the same specifications, the pull-out resistance of J-shaped anchor bolts is usually 20%-30% higher than that of L-shaped ones.
2. J hook concrete anchors excellent anti-rotation performance
The arc structure of the J hook can effectively resist the rotational loosening of the bolts during vibration, and is more stable than the L-shaped one.
Especially suitable for long-term vibration environments (such as tower cranes and large motors).
3. J anchors for concrete deeper burial is more secure
The J-shaped hook can be completely buried deep in the concrete, and the anchoring depth is usually greater than that of the L-shaped one.
The entire hook can be buried in the concrete
It can withstand tossing and it is not easy to come out even if the soil is soft, reducing the risk of pulling out.
4. concrete J anchors reasonable structural design, not easy to damage
It is especially suitable for places that are subjected to stress every day, such as bridges and signal towers. The stress distribution of the J-shaped structure is more uniform, and it is not easy to break when subjected to alternating loads for a long time.
5. FIXDEX & GOODFIX J bolt construction advantages:
The bending direction of the J-hook can be fixed in advance to ensure that the bolt angle does not deviate after pouring.
It is especially suitable for installations that require strict alignment, such as steel structure columns.
If you want to fix something that is often pulled up and vibrates every day, such as a large windmill or a large crane, you can’t go wrong with this “fishhook bolt”! It is more secure than ordinary L-shaped bolts, but it must be buried in advance and cannot be installed later.
Choose L screws if:
The equipment has large lateral force (such as machine tools and conveyor belts).
Need to be installed later or adjusted flexibly (such as warehouse shelf modification).
(FIXDEX & GOODFIX can make this J bolt and L bolt of various strengths, and the anti-rust treatment is also complete. If you need it, please feel free to ask!)
