A processing method for the connection node of a combined special-shaped column and an I-shaped steel beam

Abstract

The invention discloses a treatment method of a connecting joint of a composite special-shaped column and an I-shaped steel beam. According to the treatment method of the connecting joint of the composite special-shaped column and the I-shaped steel beam, the composite special-shaped column and the I-shaped steel beam are included. The composite special-shaped column is formed by connecting a square steel tube and a cold bend steel plate. The I-shaped steel beam is connected with the composite special-shaped column through a rigidity connecting joint or a hinge joint connecting joint, and thenthe connecting joint is subjected to fabrication processing. According to the treatment method of the connecting joint of the composite special-shaped column and the I-shaped steel beam, the composite special-shaped column is adopted to be connected with the I-shaped steel beam to make the connecting joint bear force evenly and be safe and reliable; supporting strength of the I-shaped steel beamis improved; the composite special-shaped column is machined and shaped between workshops; and construction efficiency is greatly improved. In addition, the composite special-shaped column is filled with concrete and the whole strength is improved. According to the treatment method, construction is easy; procedure is simple; the construction cost is greatly reduced; and the fire resistance rate ofthe connecting joint is improved, and meanwhile, the thermal insulation property and the sound insulation property of the whole wall surface are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of steel structures and relates to a processing method for connecting nodes of combined special-shaped columns and I-shaped steel beams. Background technique [0002] At present, in multi-storey residential buildings and multi-storey villas in civil buildings, the commonly used structural forms are masonry structure, concrete frame structure, and steel structure frame. For the masonry structure, the main load-bearing structure (load-bearing wall) is made of bricks (or other blocks), which is a brittle material with acceptable compressive strength, low tensile and shear strength, so the seismic performance Poor and limited. The concrete frame structure and steel frame structure are more flexible in room layout, but some columns are too large in section size, which will protrude outside the wall and affect the appearance. Therefore, the frame structure is more suitable for long-span public buildings, multi-st...

Problems solved by technology

For the masonry structure, the main load-bearing structure (load-bearing wall) is made of bricks (or other blocks), which is a brittle material with acceptable compressive strength, low tensile and shear strength, so the seismic performance poorer, more limited

The concrete frame structure and steel frame structure are more flexible in room layout, but some columns are too large in section size, which will protrude outside the wall and affect the appearance. Therefore, the frame structure is more suitable for long-span public buildings, multi-storey industrial plants and some special-purpose buildings. in the building

The steel tube beam composite shear wall structure developed by Hangxiao Steel Structure Co., Ltd. avoids the impact of excessive column cross-section on residential comfort, but the steel tube beam shear wall is more suitable for high-rise residential buildings. For multi-storey houses and multi-storey villas, use The steel tube beam shear wall structure is too expensive and does not meet the economic principles of the building structure
