To solve the disadvantages of large individual weight and the need for multiple supports during construction of prefabricated concrete wall panels,a support-free segmented prefabricated concrete wall panel was designed and constructed based on actual engineering.Combined Ultra-High Performance Concrete(UH-PC)cast-in-place connecting sections with embedded anchor bolts,the following effects were displayed.First,during installation,rapid anchoring force required for installation was provided through embedded bolts and con-nection boxes,with little installation difficulty.Second,during service stage,anchoring force was provided through cast-in-place UHPC connections,preventing cracking and leakage in the prefabricated precast wall pan-els.At last,traditional large wall panel was divided into smaller blocks to reduce the weight and volume of indi-vidual wall panel,convenient for transportation and installation.Massive support structures were eliminated to improve construction efficiency and quality.
