Abstract

The invention discloses an assembly type concrete composite box beam and a construction method thereof. The assembly type concrete composite box beam is provided with a steel frame, a reinforced concrete beam reinforcement cage and concrete. The steel frame is divided into a left end steel frame portion, a middle steel frame portion and a right end steel frame portion in the extending direction of the assembly type concrete composite box beam. Both the left end steel frame portion and the right end steel frame portion are provided with support steel components and support additional flange steel components. The middle steel frame portion is provided with a lower supporting steel component, upper front side supporting angle iron, upper rear side supporting angle iron, a plurality of front beam side hoop plates and a plurality of rear beam side hoop plates. The left end steel frame portion, the middle steel frame portion and the right end steel frame portion are provided with a plurality of beam face hoop plates and a plurality of inner rib plates. The reinforced concrete beam reinforcement cage is arranged in the steel frame in a wrapped mode. The assembly type concrete composite box beam has the advantages of being simple in structure, convenient to manufacture and mount, capable of shortening the construction period and reducing steel consumption, economical, high in bearing capacity, good in stability, high in bending resistance and shearing resistance, high in rigidity and resistant to shock, wind, corrosion and fire.

Description

technical field [0001] The invention relates to an assembled concrete composite box girder and a construction method thereof, belonging to an industrially produced assembled building system. Background technique [0002] The General Office of the State Council issued "Several Opinions on Promoting Housing Industrialization and Improving Housing Quality" in 1999. On January 1, 2013, in the form of Document No. 1 in 2013, the State Office of the National Development and Reform Commission and the Ministry of Housing and Urban-Rural Development "Green Building Action Plan" was forwarded. [2013] No. 1 Annex 1), the document focuses on fully understanding the development of green building actions, and lists "promoting the industrialization of construction" as one of the ten important tasks. [0003] At present, the structural beams used in various places mainly include cast-in-place reinforced concrete beams, prefabricated assembled reinforced concrete beams, shaped steel concrete...
