EXPERIMENTAL STUDY OF THE NEW-TYPE HORIZONTAL FORMWORK OF FAST INSTALLATION AND EARLY DISMANTLING

Full size experiments were used to analyses the bearing capacity of a new-type horizontal formwork of fast installation and early dismantling，the tests focused on testing the performance influence of construction loads on the system and the mechanical properties of the system and engineering practicality after early demolition． It was concluded that the frame body was safe under 18. 5 kN load by setting six strain-points and eight displacement-points to measure on the experimental model under continuous load and also measuring the overall deformation and bearing capacity of the frame body． In addition，when the new pouring concrete strength reaches 38%，the frame body was removed first the early and retaining pole support retained independently． The experiment results showed that the structure was in a safe state． The experiment results provide strong support for the promotion and application of the frameworks，and the experiment methods also provide some reference for the experiments of relevant scaffold．
