Abstract


With the rapid development of China 's highway , and the acceleration of the process of urbanization , highway cloverleaf bridge , Interchange Area , the hub of the ramp bridge urban overpass and viaduct cast-in-place in the form of more and more bridges , more construction methods used in the steel formwork supporting cast-in-place process . Cuplock steel bracket because of its good performance characteristics , become the bridge construction bracket form . However, due to the lack of structural system design theory , to match the technical specifications of the lag and imperfect , plus on construction management and material quality defects , leading to recent years Cuplock scaffolding and formwork in bridge construction constantly collapse occurred . Cuplock steel bracket analysis and research , has important practical significance . The main contents of this paper are as follows : analysis summarizes reasons caused the accident by a large number of research and collecting accident example steel formwork in bridge construction , and targeted strategies and measures proposed to prevent accidents ; of bridge construction the advantages and disadvantages of the three kinds of stents compared Cuplock steel stent performance characteristics are introduced, and practical engineering application of new scaffolding support system should follow the basic principles and bracket system erection program , under special conditions erection methods research note ; Cuplock specification current study , pointed out that the unreasonable or inadequacies , and put forward suggestions for improvement ; pair the bracket pre pressure and Precamber of setting study , combined with the purpose of the bridge construction formwork preload preload load and preload plus , uninstall way , and the introduction of the engineering example ; analysis of the role of the various loads on the stent system , determine the load calculation method using the ABAQUS finite element procedures to establish the spatial model analog formwork support the forces with engineering examples , the formwork design calculations , to ensure that the bridge formwork construction safety , to provide a reference for formwork design and construction of such structures experience and ideas of reference .
