Heavy-duty high-strength rear belling bolts NJMKT-UA PNJMKT series heavy-duty high-strength rear belling bolts, over seismic fatigue resistance and no loosening test, salt spray test 3 100 hours at the end of rust!Crack Concrete Flip Report!The NJMKT post-belled mechanical anchor uses the reaming wall at the bottom of the hole to tangent with the lock key of the mechanical anchor bolt to form a lock key effect and complete the anchoring effect.
It can withstand high loads, and can be used to withstand impact and ** loads.
When using NJMKT's dedicated reamer bits, it has a true mechanical key-locking effect.
The non-inflating force generated by the mechanical lock key ensures the effective propagation of force in the concrete.
Carter strong rear belled bolt advantage 1It has a high load-bearing capacity, fatigue resistance, vibration resistance, firm and reliable.
2.There is no expansion stress, and the initial stress applied to the concrete substrate is small, which is suitable for small margins and small spacing.
3.It is suitable for all special environments where reinforcement is not suitable for planting or using chemical anchors.
4..There is a clear installation scale on it, which is easy to install.
5.There are different materials according to different use environments to meet the various needs of customers.
6.The varieties and specifications are complete, and various special specifications can also be customized according to the requirements of construction.
7.There is a special reaming drill bit, which can be quickly reamed and installed quickly.
8.It is suitable for anchoring on cracked concrete with high requirements, and can resist vibration and impact loads.
9.It can be carried with a small torque and has a built-in mechanical locking effect.
10.Accommodates variable anchorage depths and variable fixation thicknesses.
11.High anti-corrosion series 3000 hours salt spray test without rust.
Scope of application of belled bolts after heavy strength: 1Occasions with high requirements, such as nuclear power plants, etc.
2.Installation and fixation of large equipment in industrial plants, conveyor systems, lifting systems.
3.Connection and fixing of various curtain wall structures and steel structures.
4.Installation and fixing of various pipelines in civil buildings, such as water and electricity pipelines, fire pipes.
5.Railway, tunnel, bridge and other types of pipes, cable support installation and fixation.
6.Installation of various anti-theft doors, fire doors, and anti-theft windows.
7.Elevator installation.
8.Reinforced with bonded steel.
