Beam column connection piece, building framework structure and mounting method

Abstract

The invention provides a beam column connection piece, a building framework structure and a mounting method. The beam column connection piece comprises a beam column connection piece body, a stand column splicing head, and a beam splicing head, which are integrally formed; the beam splicing head comprises a first supporting part for directly supporting a lower flange of a beam, and a first fixing part which is arranged above the first supporting part, is horizontally and convexly arranged on the lateral face of the beam column connection piece body, and is fixedly connected with a web of the beam; a distance between the first supporting part and the first supporting part in a vertical direction is more than the thickness of the lower flange of the beam; the width of the first fixing part in the vertical direction is less than a distance between the two opposite faces of the two flanges of the beam; and the beam column connection piece is further provided with a stopping part of the end part of a stand column. The beam column connection piece has the advantages in that the end part of an H-shaped or transverse H-shaped beam has no need of being machined and has more connection and fixation positions; the connection nodes are stable and reliable; the strength and the rigidity of the connection position are good; and the building framework structure has the advantages of convenience in installation, less process and low labor intensity.

Description

technical field [0001] The invention relates to a beam-column connector, a building frame structure and an installation method of houses, pavilions, booths, bridges and other buildings, in particular to a beam-column connector, a frame structure and an installation method of a building frame steel structure. Background technique [0002] In the invention patent with application number 201110114982.3, a beam-column connector and its forming method, building frame structure and installation method are disclosed. The beam-column connector includes an integrally formed beam-column connector body, a column plug connector, and a horizontal support connector. Although this patent has greatly reduced fastening connections such as bolts or welding connection links, it has greatly reduced the defects of excessive stress concentration on the connection position between beams and columns or between beams and beams, which makes the connection position poor in stress and weak in connectio...

Problems solved by technology

In this patent, in order to install the crossbeam as H-shaped steel or I-shaped steel, the end of the crossbeam is processed into a T shape, which increases the process and increases the cost; The two position-limiting protrusions and their corresponding side protrusions form an accommodating groove, and each side wall of the accommodating groove is provided with a fastener fixing threaded hole; the horizontal part of the T-shaped end of the beam ( The upper wing plate) is directly supported on the top surface of the limit protrusion, the vertical part (web) is accommodated in the accommodation groove, and the fastener passes through the fastener to fix the threaded hole and the T-shaped end of the beam. The abutment of the vertical part fixes the beam with the two limiting protrusions, and only the vertical part is connected and fixed with the two limiting protrusions through fasteners. There are few connection and fixing positions, which affect the connection strength and stiffness of the joint; and because the vertical part There is a gap between the beam and the accommodating tank, and the fasteners cannot be used to completely fix the beam and the beam-column connector. There will be a certain gap between the beam and the beam-column connector, so spot welding is necessary after fixing with the fastener fixed
