The Positioning Technology and Innovation of Independent Foundation Column Base Pre-Embedded Anchor Bolts
The anchoring method between the independent foundation and steel columns in steel structure buildings typically involves the use of pre-embedded anchor bolts.The precision of the pre-embedded anchor bolts at the column base directly affects the overall verticality,planar bending,and other positional deviations of the steel columns and the superstructure,making it a crucial control aspect in the installation and construction of steel structures.Due to the suspended installation of pre-embedded anchor bolts within the independent foundation,the positioning and reinforcement of anchor bolts present significant technical challenges.Traditional construction methods consume a large amount of auxiliary reinforcement,resulting in disadvantages such as long cycles,low work efficiency,high volume of onsite welding,and reduced load-bearing performance due to welding of the anchor bolts.To address the bottlenecks of traditional processes,a new positioning device for pre-embedded anchor bolts in independent foundations,which has been patented,has been developed through equipment innovation.Additionally,the key construction techniques involved in its design,fabrication,and construction have been elaborated.Practical application has shown that this new technology for the positioning of pre-embedded anchor bolts allows for the positioning device to be commonly reused,achieves high precision in pre-embedding the anchor bolts,provides stability and reliability,and simplifies processes and reduces costs,fundamentally ensuring the installation quality of steel structures.
