Linear controlling device and method suitable for steel-structural special-shaped tower

Abstract

The invention discloses a linear controlling device and method suitable for a steel structure special-shaped tower. The special-shaped tower is an arched curvilinear tower, a tower body is formed by an erected section on the lower portion and a curvilinear section on the upper portion, the linear controlling device includes a supporting system, an erected section transposition system, an erected section locking system, a curvilinear section transposition system and a curvilinear section locking system, the supporting system is arranged in the arched curvilinear tower, and the arched curvilinear tower includes a latticed column section on the upper portion, a girder section on the middle portion and an upright-column supporting and adjusting section on the upper portion. The erected section transposition system, the erected section locking system, the curvilinear section transposition system and the curvilinear section locking system all rely on the supporting system 1 to achieve steel tower installation and linear controlling. According to the linear controlling device and method suitable for the steel structure special-shaped tower, specially-shaped-section slant steel tower hoisting installation and space-variation slant steel tower hoisting installation are achieved, the construction time is shortened, and costs and construction risks are reduced; the limitation of the prior art is overcome, and the requirement of the linear installation accuracy can be ensured when the linear controlling device and method are used for mounting steel towers of any structure shapes.

Description

technical field [0001] The invention belongs to the field of building structure and construction, and is suitable for the installation and construction of special-shaped steel structure towers. Background technique [0002] With the development of our country's economy, some bridges with novel shapes, as "a business card" of urban landscape, play a pivotal role in urban form and urban landscape. These bridges are novel in structure and unique in shape. Landmark buildings, such as: Guangzhou Liede Bridge, Nanjing Youth Olympic Pedestrian Bridge, etc. [0003] Since these bridges mostly adopt special-shaped cross-sections composed of curves and straight lines, the cross-sectional size is large and the space changes, and the steel towers are often inclined vertically, the structure is complex, and the weight is generally large. The construction is difficult and risky, especially in section The matching of segments and the installation accuracy of linear control are more and mo...

Problems solved by technology

[0006] 2) Limitations of traditional methods:

[0007] Traditional guiding positioning has a good effect on the docking of straight towers with variable cross-sections, but it has great limitations in the corresponding space of special-shaped towers:

[0008] (1) Only the butt joint accuracy of the upper and lower adjustment sections can be guaranteed, but the overall alignment of the steel tower cannot be guaranteed

[0009] (2) For space curved towers, especially arched curved towers, this method cannot meet the requirements of precise adjustment
