RESEARCH ON CONSTRUCTION TECHNOLOGY AND OPTIMIZATION OF TAPERED BOLT HOLE PLUGGING OF ALUMINUM MOLD EXTERIOR WALL
In order to study a more efficient and practical technology for sealing bolt holes in aluminum-mold shear wall.Theoretical analysis,experimental research and engineering application are used to investigate the characteristics of the traditional sealing technology of bolt holes in aluminum mold shear wall,at the same time,the experimental research on the plugging material mixture ratio was carried out.Finally,a high-efficient plugging tool was developed,and the optimum mixture ratio of expansion agent and 108 adhesive was determined.The quality of the construction technology of sealing the conical bolt hole of the aluminum alloy formwork outer wall is evaluated by the three tests of the sealing strength of the screw hole,the water-facing test of the screw hole and the strength of the mortar bar.The results show that the optimized construction technology can save material and meet the strength requirement.It is concluded that the optimized construction technology can provide reference for similar engineering construction.
