Abstract

The invention provides an integrally assembled frame adopting U-shaped steel transverse connection and a construction of the said frame. The integrally assembled frame comprises a reinforced concrete prefabricated pillar (1), a reinforced concrete prefabricated beam (2) and U-shaped steel (4), wherein the reinforced concrete prefabricated pillar (1) is provided with a short beam section (3). The end of the short beam section (3) of the reinforced concrete prefabricated pillar (1) is provided with a first bolt hole, a web of the U-shaped steel (4) is provided with second bolt holes (52), and two ends of the reinforced concrete prefabricated beam (2) are provided with third transverse bolt holes (53). The reinforced concrete prefabricated pillar (1) and the reinforced concrete prefabricated beam (2) are connected by the U-shaped steel (4) and transverse high-intensity frictional bolts (6), and engineered cementitious composite is cast in a connection area, so that the integrally assembled frame is formed. The integrally assembled frame has the advantages of clear and reliable internal force transmission, simplicity and reasonableness in stress, convenience and efficiency in construction method, high integral performance and good anti-seismic property and the like.

Description

Technical field: [0001] The invention relates to a reinforced concrete assembled integral frame with U-shaped steel transverse connections and a construction method thereof, belonging to the field of construction engineering concrete frame structure technology and construction. technical background: [0002] Reinforced concrete prefabricated integrated frame structure is an important direction for the future development of building industrialization. It has the advantages of short economic cycle, high quality prefabricated components, less on-site wet work, less environmental pollution, faster construction progress, lower labor intensity of workers, and is conducive to energy saving and reduction. Consumption and environmental protection and other advantages. This structural system has been widely used in developed countries and has become the main form of new buildings in some countries. The connection technology is the core issue of the reinforced concrete prefabricated i...
