Abstract

The invention discloses a giant pre-stressed string structure suitable for enclosing a super-long-span coal yard and a construction method. The structure comprises a group of pre-stressed string structure units arranged in parallel at intervals, wherein every two adjacent pre-stressed string structure units are connected through connecting structures; each of the pre-stressed string structure unit comprises a space truss and a string cable connected below the space truss in a tensioning way; a group of support trusses is vertically connected between the space trusses and the string cables. In the structural system, small-sized triangular space trusses are taken as sub-structures for replacing chord members, web members and brace rods in the string structure to form a giant composite string structure; upper chord trusses, diagonal web trusses, horizontal web trusses and lower chord trusses can be prefabricated in a factory and assembled into the space trusses on site, and then the space trusses are mounted in place through a group slippage method, so that high construction efficiency is achieved; moreover, running of yard equipment is not influenced during construction, equipment modification is not required, factory shutdown is not required, the manufacturing cost is lowered, and resource waste is reduced.

Description

technical field [0001] The invention relates to the field of building transformation, in particular to a closed structure for coal yard transformation and a construction method thereof. Background technique [0002] In order to reduce and avoid serious air pollution and smog weather caused by dust escape from the coal yards of power plants, steel mills, coal chemical enterprises and other enterprises, the coal yards need to be closed for renovation, but the normal production and existing loading and unloading in the coal yards cannot be affected during the renovation process. This requires a canopy to be closed on the existing stockyard, and it is a super-long-span column-free space structure with a large structural span. At the same time, it must be safe and reliable, and requires convenient construction. [0003] The prestressed string beam structure is a prestressed steel structure system composed of a rigid arch combined with cables and struts with better spatial force. ...
