AI Technical Summary
Technical Problem
In the current construction of concrete tower segment assembly, the application of structural adhesive and the tightening of bent bolts cannot be precisely controlled, resulting in poor assembly effect and extended construction period.
Method used
By dynamically controlling the surface drying time and pot life of epoxy structural adhesive, combined with real-time ambient temperature and humidity, the timing of tightening is precisely determined, and the final tightening parameters are corrected based on the adhesive layer thickness feedback, thus achieving high-quality assembly.
Benefits of technology
Ensure the stress reliability and sealing durability of the glued plug composite connection node, shorten the construction cycle, and reduce rework time.

Abstract
The present disclosure relates to the technical field of concrete tower drum construction, and relates to a splicing construction method of a concrete tower drum segment. The method comprises the following steps: determining a surface drying time and a suitable period according to an environmental temperature, an environmental humidity and a binder characteristic parameter; mixing a first component and a second component to obtain uniformly mixed epoxy structural adhesive, and applying the uniformly mixed epoxy structural adhesive on a splicing surface; inserting a bent bolt into a bolt hole and corresponding installing a locking nut; determining a first pre-tightening torque application time according to a glue application end time, the surface drying time and a pre-tightening window time, and applying a pre-tightening force value of a first proportion of a preset tightening force to the bent bolt; determining a second final tightening torque application time according to a uniform mixing time, the suitable period and a final tightening window time; correcting the second final tightening torque application time and / or the second final tightening force to determine a target application time and a target application force, and applying a tightening force to the bent bolt to obtain an initial tower drum structure; and processing the initial tower drum structure to obtain a target tower drum structure.
