Steel component concrete encasement construction technique

The invention discloses a construction technology of wrapping concrete outside the steel member. The construction technology adopts the procedures: firstly, concrete is prepared; secondly, the first layer of reinforcing steels are prepared outside the steel member, and the space distance between the adjacent two reinforcing steels is not less than 80 mm; thirdly, concrete is sprayed to the surface of the steel member, and the concrete thickness is controlled between 70 mm to 100 mm; fourthly, the second layers of reinforcing steels are prepared outside the concrete layer; fifthly, concrete is sprayed according to the third procedure; sixthly, according to the requirements, the fourth and fifth procedures are repeated, and the concrete is cured according to the convention. The construction technology of the invention can avoid problem existing the prior casting method for wrapping concrete outside the steel member, mould plates are not required or less mould plates are required, therefore the investment is gre
