What Is a Superbolt?
Tie bolts (twin bolts) are used to tie the inside and outside formwork of the wall to withstand the lateral pressure of the concrete and other loads, ensuring that the space between the inside and outside formwork can meet the design requirements, and it is also the formwork and its supporting structure Fulcrum. Therefore, the arrangement of the tension bolts has a great impact on the integrity, stiffness and strength of the formwork structure.
The tension bolts are generally round steel bolts threaded at both ends, also known as

Therefore, the arrangement of the tension bolts has a great impact on the integrity, stiffness and strength of the formwork structure.
The tensile stress on the tension bolt exceeds the stress limit that the bolt and the tie rod can withstand.
The tension bolts should be made of high-strength steel, and the contact area between the bolts and the rod threads can be increased, and the tensile stress bearing value can be increased under the same diameter. The most important thing is to choose the tension bolts with suitable strength and size according to the structure and force.
