Hybrid type row-frame for city trestle construction

The utility model relates to a hybrid bent used in construction of urban viaduct. The utility model consists of a group of steel pipe upright posts that are arranged at intervals, the bottom of the steel pipe upright posts is fixed on the concrete foundation, and an upper part ot the steel pipe upright posts are fixedly connected with a beam. The utility model is characterized in that horizontal vertical planes and transverse vertical planes of the adjacent steel pipe upright posts are fixedly connected with scissors, and channel steels are horizontally connected in the middle to form an integral rigid frame. Adopting a hybrid support, steel content per cubic meter of the utility model is greatly decreased compared with traditional steel pipe full space supports, thus greatly improving the stability of the bent and saving engineering cost; at the same time the utility model meets the requirement for high girder deck of a site cast box, large box size, construction operation range confined by multilevel traffic and conducting construction under complex construction conditions.
