Retractable beam used for elevator shaft formwork platform
A retractable beam used for an elevator shaft formwork platform comprises a fixing beam, an adjusting beam and automatic resetting pawls installed at one end of the adjusting beam. I steel at one end of the fixing beam is installed between two steel channels of the adjusting beam in a sleeved mode, a first lower pressing block is welded to the bottom of the adjusting beam, a first upper pressing block is locked to the top of the adjusting beam through a bolt assembly, and a second upper pressing block and a second lower pressing block are locked to the top and the bottom of the I steel of the fixing beam through bolt assemblies respectively. Each automatic resetting pawl comprises vertical plates, a balancing weight and a rolling wheel, wherein the balancing weight and the rolling wheel are installed at the two ends of the vertical plates respectively. The middle portions of the vertical plates are connected with the adjusting beam at the end of the retractable beam through pin shaft assemblies. The length of the beam can be freely adjusted within a certain range, the beam is adapted to constructing tube type cast-in-place shearing walls of different shapes and section sizes and can be lifted inside an elevator shaft and achieve stable positioning landing on each layer, in this way, efficiency of building construction is greatly improved, manpower and material resources are saved, repeated using can be achieved, and the safety coefficient is high.
