Abstract

The invention provides a diagrid sleeve structure for restricting connection of high strength concrete nodes, relates to a diagrid sleeve structure in the field of civil engineering, and aims to solve the problems that the conventional reinforced concrete node with the diagrid sleeve structure has lower bearing capacity and high brittleness, is difficult to meet the basic requirements of strong nodes and weak components, and the like. In the structure, the upper end of each reinforced concrete column is connected with lower ends of two reinforced concrete counter braces through a high-strength concrete brace conversion node; every two high-strength concrete brace conversion restriction nodes are connected through a reinforced concrete gird; every four reinforced concrete counter braces are connected through a high-strength concrete vertical surface restriction cross node; every two high-strength concrete vertical surface restriction cross nodes are connected through a reinforced concrete gird to form a diagrid vertical surface; and the diagrid vertical surfaces in two adjacent directions are connected through a high-strength concrete space joint node to form the diagrid sleeve structure. The diagrid sleeve structure can be used for an outer sleeve of a super-high rise tube in a tube structure.

Description

technical field [0001] The invention relates to an oblique grid tube structure, in particular to an oblique grid tube structure connected by constrained high-strength concrete nodes, and belongs to the field of civil engineering. Background technique [0002] As the outer tube of the tube-in-tube structure of a super high-rise building, the reinforced concrete oblique grid tube structure is mainly formed by connecting reinforced concrete slanted columns and horizontal girders through various joints at the intersection of façades, the conversion of slanted columns or the intersection of spaces. Wind, earthquake, building self-weight and service loads have huge internal forces such as slanted columns and girders, especially the various nodes connecting slanted columns and girders as the main force transmission unit, the force is more complicated, and the internal force with huge values ​​is complicated. deformation. However, various types of reinforced concrete joints with lo...
