Description

Steel supporting structure Technical Field The utility model relates to the field of building construction, in particular to a steel supporting structure. Background The foundation pit steel support is an important temporary support structure used in the deep foundation pit excavation process, and mainly aims to prevent soil body on the side wall of the foundation pit from slipping or collapsing and ensure construction safety. In urban construction and underground space development, as the demand for underground space utilization increases, the scale and depth of foundation pit engineering also continuously increase, and the application of foundation pit steel supports is becoming wider and wider. Traditional steel is being built the installation time, is fixed in between the steel purlin of both sides generally, and when the span of steel was supported than great, need build the stand on ground, realizes the support of steel support middle part position to be used for guaranteeing the stability of steel support. However, when the traditional upright post is constructed, the blanking is carried out according to the measured height after the on-site measurement is needed, and then the welding assembly is carried out.
