In groove steel rail；The groove steel rail is placed on Vierendeel girder；The support bracket is embedded in frame column；The overturn-preventing
Device is connected by Vierendeel girder with steel truss；The steel truss is provided with multistage support channel-section steel.
Above-mentioned hanging large-span steel-reinforced concrete structure construction steel platform, the steel truss is by three Pin main couples, six Pin purlins
Frame and secondary beam composition.
Above-mentioned hanging large-span steel-reinforced concrete structure construction steel platform, the support bracket is welded by H profile steel and pre-embedded steel slab
Connect and form.
Above-mentioned hanging large-span steel-reinforced concrete structure construction steel platform, the Overthrow preventing device by U-shaped ring, punched steel plate,
Nut and H profile steel column composition.
Above-mentioned hanging large-span steel-reinforced concrete structure construction steel platform, the steel truss is realized along groove by bottle gouard moved by hands
Steel track slides.
The utility model has the advantages that in summary：The present invention has reasonable in design, structural bearing capacity
The advantages of big and safe use, it is ensured that hanging large-span steel-reinforced concrete structure construction quality, it is effectively protected staff's
Life security, and the operation of staff is greatly facilitated, improve operating efficiency.
