As an efficient and reliable building connection technology, drop in anchor play an important role in the field of modern engineering. Its core function is to firmly combine metal components with concrete substrates by pre-embedded or post-installed methods. It is widely used in scenes such as building curtain wall installation, equipment base fixation, and steel structure connection.
In the construction of high-rise building curtain walls, drop in anchor can effectively bear the deadweight load and wind load of the curtain wall system by determining the implantation depth and spacing through precise mechanical calculations. Its concealed installation characteristics not only ensure structural safety, but also maintain the integrity of the building's appearance. The fixation of heavy equipment in industrial plants often adopts a specially designed embedded anchor bolt system. Through the dual protection of shear resistance and pull-out resistance, the stability of the equipment under vibration conditions is ensured. This connection method is more convenient for later maintenance and adjustment than traditional welding.
In the field of existing building renovation, the application of drop in anchor is particularly prominent. When it is necessary to reinforce old bridges, technicians can drill holes on the surface of concrete beams and implant high-strength anchor bolts, which can form a reinforcement system with steel plates. This non-destructive reinforcement method can not only improve the structural bearing capacity, but also retain the integrity of the original structure to the maximum extent.
The installation of drop in anchor requires strict adherence to the process flow. After precise positioning, special drilling tools are used to drill holes, the dust in the holes is thoroughly cleaned, chemical anchor glue or mechanical bottom expansion technology is used to achieve reliable bonding, and finally the pull-out force test is performed to ensure that the quality meets the standards.
With the development of building industrialization, new nano-modified epoxy adhesives and intelligent monitoring drop in anchor are gradually being promoted. Such innovative technologies enable anchor systems to have higher weather resistance and real-time health monitoring functions, further broadening the scope of application of this technology in complex engineering environments.
