Concrete filled steel tubular column-H-shaped steel beam-steel support-pi-shaped connecting piece combined corner column middle joint and manufacturing method

Abstract

The invention discloses a concrete-filled steel tube column-H-shaped steel beam-steel support-pi-shaped connecting piece combined corner column middle joint and a manufacturing method. The joint is mainly composed of a light square steel tube recycled concrete column, an H-shaped steel beam, pi-shaped connecting pieces, web connecting plates, high-strength bolts, steel supports, cross-shaped benchtie bars and a prefabricated recycled concrete local floor slab. The beam-column-support connecting joint is easy and convenient to construct, environmentally friendly and clear in force transmissionpath and has two seismic defense lines. The pi-shaped connecting pieces increase the height of the joint area, the bearing capacity of the joint is improved, the pi-shaped connecting pieces on the two adjacent sides of the corner column are discontinuous, and the risk of continuous collapse of the structure is reduced. Cross-shaped stool tie bars are used for tying adjacent joint areas of the corner columns and the floor slabs, and the joint integrity is enhanced. The joint beam-column-support-floor slab is firm in connection, high in integrity and excellent in anti-seismic property, and keytechnical support is provided for engineering design of a light steel composite structure of an assembly type green house.

Description

technical field [0001] The invention relates to a joint in the middle of a corner column of a combined type of concrete filled steel pipe column-H-shaped steel beam-steel support-π-shaped connector and a method thereof, belonging to the technical field of structural engineering. Background technique [0002] With the continuous improvement of the national economy, my country's urbanization process is accelerating, and the scale of construction projects is also expanding. The traditional architectural structure can no longer meet people's actual needs for buildings. made a significant contribution to its development. Compared with traditional buildings, prefabricated structures have fast construction speed and high efficiency, short construction period, good overall building quality and low cost, which is conducive to winter construction and has good environmental protection performance. At the same time, with the introduction of environmental protection policies such as ener...
