Dry construction connecting structure of duct corners and girder for building with fabricated frame structure

Abstract

The invention discloses a dry construction connecting structure of duct corners and a girder for a building with a fabricated frame structure. The structure comprises prefabricated columns and the steel girder; the steel girder is connected with the prefabricated columns by means of the duct corners which are respectively arranged at the upper side and lower side of the end of the steel girder; split bolts are pre-buried in the prefabricated columns; one ends of the split bolts are arranged in the prefabricated columns, and the other ends of the split bolts extend outside the prefabricated columns and pass through a first connecting plate; the split bolts are positioned in the prefabricated columns and are connected with longitudinal steel bars in the prefabricated columns in a welding way. According to the connecting structure provided by the invention, the split bolts and the longitudinal steel bars form a whole, so that the ultimate bearing capacity and anti-seismic property of theframe structure are improved; furthermore, the pre-buried split bolts are prevented from shifting in a construction process of the prefabricated columns, so that the construction accuracy is guaranteed. The connecting structure is simple in structure and convenient for construction, and greatly improves the construction quality and shortens the construction period under the premise of guaranteeingthe construction structuring strength of the frame structure.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a dry construction connection structure between a corner column and a beam for a prefabricated frame structure building. Background technique [0002] Frame structure is a building structure system that is composed of beams and columns to bear vertical loads and lateral loads. It is widely used in residential buildings, office buildings, shopping malls, hotels and multi-storey industrial plants. The dry construction connection structure of the frame structure building is a building assembled on site by using prefabricated beams and columns. people's attention. However, the existing reinforced concrete prefabricated columns and prefabricated beams have relatively high compressive strength and relatively weak tensile strength, especially when prefabricated columns and prefabricated beams are connected by corner joints, the ports of the prefabricated beams are easily ...
