Connection node structure of row steel pipe concrete special-shaped column and beam and building structure system

Abstract

The invention relates to a connection node structure of a row steel pipe concrete special-shaped column and beam and a building structure system. The connection node structure mainly comprises a prefabricated row steel pipe concrete special-shaped column, a steel beam and a shear-resistant wall, the shear-resistant wall is an ultra-high performance concrete sandwich panel, and a wallboard and the steel beam are assembled into a whole in a factory; a node position row steel pipes are connected with the steel beams through steel sleeves, connecting plates and vertical plates, and reliable tension and pressure transmission of upper and lower flange steel beams is guaranteed. An anti-seismic system of a row steel pipe special-shaped column frame and the shear wall is adopted, the shear wall bears most horizontal loads, and a first defense line is provided for seismic fortification; the row steel pipe special-shaped column frame mainly bears vertical force and serves as a second defense line for the seismic fortification, a double-layer lateral force resisting structure system is formed, and the seismic performance is excellent. The vertical load of the system is mainly transmitted to the steel beams through floor slabs and transmitted to the row of steel pipe special-shaped columns through the steel beams; the shear-resistant wall is connected with the steel beam through a shear-resistant connecting piece, the shear-resistant wall only bears the horizontal load and self weight transmitted by the steel beam, and the overall anti-seismic performance is reliable.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a connection node structure and a building structure system of row concrete-filled steel tube special-shaped columns and beams. Background technique [0002] Precast concrete is concrete from which concrete products are made at the factory or on site (not at the final design location). Precast concrete is poured elsewhere rather than at the final construction site. Precast concrete of different sizes and shapes can use fibers to enhance its reliability and toughness after cracking. [0003] Precast concrete has become the new darling of the construction industry because of its low cost and excellent performance. A wide variety of styles and weights combined with excellent flexural strength and performance allow for a wide range of applications in barricades, cisterns, facades, architectural and decorative applications. Precast concrete can accelerate the speed...

Problems solved by technology

[0004] The connection technology between precast concrete is the key to the prefabricated integrated reinforced concrete system. At present, the joint connection between precast concrete special-shaped columns and beams is complicated, and the seismic performance is poor.
