Abstract

The invention relates to a double-layer quadrangular-pyramid reticulated-shell steel-structure cooling tower, in particular to a locally reinforced double-layer quadrangular-pyramid reticulated-shellsteel-structure cooling tower, and belongs to the field of civil engineering. The locally reinforced double-layer quadrangular-pyramid reticulated-shell steel-structure cooling tower aims to solve theproblems that an existing ultra-large type single-layer steel-structure cooling tower is high in fabricated construction difficulty, low in bearing capacity and height and high in construction cost.The locally reinforced double-layer quadrangular-pyramid reticulated-shell steel-structure cooling tower comprises a double-layer reticulated shell, a lattice type oblique stand column, a plurality ofcircumferential reinforcing trusses and a plurality of longitudinal reinforcing trusses, and the multiple circumferential reinforcing trusses are sequentially arranged from top to bottom; and the multiple longitudinal reinforcing trusses are installed on the circumferential reinforcing trusses in the circumferential direction, the multiple circumferential reinforcing trusses and the multiple longitudinal reinforcing trusses form a frustum body with the outer contour sequentially and gradually expanding from top to bottom, the double-layer reticulated shell is installed on the frustum body ina sleeving mode, and the lattice type oblique stand column is arranged at the bottom of the frustum body.

Description

technical field [0001] The invention relates to a double-layer quadrangular pyramid reticulated steel structure cooling tower, in particular to a partially reinforced double-layer quadrangular pyramid reticulated steel structure cooling tower, which belongs to the field of civil engineering. Background technique [0002] At present, most of the natural ventilation hyperbolic cooling towers adopt traditional reinforced concrete structures, but in recent years, with the vigorous promotion of national construction industrialization and the superior structural performance of steel structures with high strength and light weight, steel structure cooling towers have become more and more popular. . However, the structural components and joints of super-large single-story steel towers have large bending moments, and the bending stiffness of fabricated joints cannot meet the requirements. With welded rigid joints, the high-altitude welding construction is difficult and the quality is...
