1. Used in formwork system of high-rise buildings to ensure overall stability.
2. For connecting and reinforcing formwork in complex projects such as bridges and tunnels.
3. Used for connecting thicker aluminum formwork or parts that need greater connection strength.
4. Suitable for large span walls, floor slabs and other construction scenarios that require high load-bearing capacity.
This long pins supports personalized customization.
Specification can be adjusted according to the application scenarios and usage conditions.
We can provide aluminum mold design drawings to suppliers and match screw specifications through load calculations; On site trial assembly checks the tightness of the pins and the sealing of the template joints to ensure seamless compatibility between the accessories and the existing aluminum mold system.
Avoid installation during the high temperature period at noon to prevent installation errors caused by thermal expansion and contraction of accessories; Properly reserve expansion gaps for screws and nuts, and promptly clean up water vapor condensed due to temperature differences for rust prevention after construction.
Clean up surface impurities in a timely manner, apply rust proof oil to easily rusted parts, store them by category, and regularly check for wear and tear.
When long pins there is fracture, severe deformation, thread wear, corrosion affecting strength, or cracking of the lifting ring weld, it must be replaced.
Standardize construction, avoid rough operations, maintain regularly, use according to the designed load, and prevent overloading.
Use a torque wrench to tighten the nut during installation, and add double nuts to key areas to prevent loosening; The dowel pin must be knocked to the bottom and checked for tightness, and reinforced with a second re inspection before pouring.
Slight deformation of accessories may cause uneven stress on the formwork, leading to local expansion or leakage of grout. It is recommended to replace it immediately to avoid losing too much due to minor issues; Timely return deformed parts to the factory for repair, reducing overall wear and tear costs.
We support personalized customization for special engineering requirements such as ultra thick walls and irregular structures. But please communicate the requirements in advance to ensure timely delivery without affecting the project schedule.
