Short angle iron connection type reinforced concrete assembling integrated frame and construction method thereof

Abstract

The invention discloses a short angle iron connection type reinforced concrete assembling integrated frame and a construction method of the short angle iron connection type reinforced concrete assembling integrated frame. The integrated frame comprises reinforced-concrete-prefabricated columns with short beam segments and reinforced-concrete-prefabricated beams. The two ends of the reinforced-concrete-prefabricated beams, the two ends of the reinforced-concrete-prefabricated columns and the ends of the short beam segments of reinforced-concrete-prefabricated columns are provided with short angle iron for connection. The upper faces of two branches of the short angle iron are provided with reserved bolt holes. The reinforced-concrete-prefabricated columns on the upper floor and the lower floor are connected through the short angle iron for connection by means of the high-strength friction type bolts. The reinforced-concrete-prefabricated beams are connected with the reinforced-concrete-prefabricated columns through the short angle iron at the ends of the reinforced-concrete-prefabricated beams and the short angle iron for connection at ends of the short beams of the reinforced-concrete-prefabricated columns by means of the high-strength friction type bolts. Fiber reinforced cement-based composite material is poured in the beam column connection region, and the assembling integrated frame structure is formed. The short angle iron connection type reinforced concrete assembling integrated frame and the construction method have the advantages of being clear and reliable in internal force transmission, simple and reasonable in stress, convenient, fast and efficient in construction method, good in whole performance, good in anti-seismic property and the like.

Description

Technical field: [0001] The invention relates to a reinforced concrete assembled integral frame connected by short angle steels and a construction method thereof, which belongs 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 integrat...
