Big steel pipe support constructional device of combination casing assembled

The utility model provides a big steel pipe support constructional device of combination casing assembled, including base, steel tube column, joint, hold in the palm on flat antithetical couplet, top. The base includes the anchor bottom plate, connects including sleeve pipe, flat antithetical couplet, otic placode, lower connecting plate, upper junction plate, and hold in the palm including the bearing roof on the top. When the support was set up, the steel tube column coxopodite was at first together fixed with base and steel pipe support basis through the fixed crab -bolt of base, then met high steel tube column through the joint, every installation one deck stand, and installation in time is flat to be allied oneself with, makes the stand form the overall structure of mutual binding each other, and steel tube column epimerite top sets up a support, and spandrel girder etc. Is installed on holding in the palm in the top, forms complete supporting structure. The device will make the support mounting simple, alleviate high altitude construction intensity, especially reduce high altitude welding volume, practice thrift construction cost, improve the efficiency of construction to can obviously improve the turnover and use the number of times, have good economic benefits.
