Double-side-plate supporting node of overhung cover plate

Abstract

The invention discloses a double-side-plate supporting node of an overhung cover plate. The double-side-plate supporting node of the overhung cover plate comprises a multi-cavity concrete filled steel tube combination column and a reinforcement type H-section steel combination beam, wherein the reinforcement type H-section steel combination beam is fixedly arranged on one side of the multi-cavity concrete filled steel tube combination column horizontally through two side plates; an upper supporting cover plate and a lower supporting cover plate, which are distributed at an oblique angle, are arranged above the reinforcement type H-section steel combination beam and between the two side plates; a supporting square pipe is horizontally pushed into the upper supporting cover plate and the lower supporting cover plate, and constitutes the double-side-plate supporting node of the overhung cover plate together with the reinforcement type H-section steel combination beam and the multi-cavity concrete filled steel tube combination column. The node is used as an edge restricting component of a whole concrete filled steel tube column; the bearing capacity and the energy-dissipating capacity of the whole concrete filled steel tube column can be improved; the multi-cavity concrete filled steel tube combination column is not damaged; materials and labor are saved. An integral structure meets the principles of a strong column and a weak beam as well as a strong node and a weak component; the double-side-plate supporting node of the overhung cover plate is provided with multiple earthquake-resistant defense lines; the destruction, which is caused as part of components are destructed, of an integral system is avoided; the double-side-plate supporting node of the overhung cover plate also has necessary strength and favorable deformability and energy-dissipating capacity.

Description

technical field [0001] The invention relates to a supporting double-side slab node of an overhanging cover slab, which is mainly applied to the steel pipe concrete composite columns of multi-storey and high-rise buildings in the building structure. Background technique [0002] With the economic globalization and the improvement of urbanization level, the urban population density is gradually increasing, which makes a large number of high-rise buildings emerge continuously. There is an urgent need for new technologies to support the design and construction of high-rise and multi-storey buildings. [0003] Concrete filled steel tube utilizes the interaction between the steel tube and concrete in the process of stress, that is, the restraint of the steel tube on the concrete makes the concrete in a complex stress state, so that the strength of the concrete is improved, and the plasticity and toughness are greatly improved. At the same time, after the steel pipe is filled with...
