Embodiment Construction

[0030] This project has one floor above the ground and one floor below the ground. The underground is an exhibition hall, and the ground is a commercial steel truss structure, mainly a space triangular tube truss structure project; including welding balls and space cables. Each part of the truss is connected by welding balls to form two hemispheres. In order to ensure the stability and stability of the two hemispheres, a flying wing-shaped truss is added to each hemisphere and connected to the hemisphere truss by cables. Make the whole structure more stable. The overall shape is a symmetrical two-lobed formwork shell with flying wings, which is novel in design, unique in shape, and evenly stressed. The horizontal projection size of the roof is about 38.2m×38.8m, and its coverage area is about 750 square meters. The top elevation of the steel truss is 9.746m. The primary and secondary trusses are mainly spatial triangular trusses with a span of 38.8m. The truss chord section i...

Abstract

The invention belongs to the field of steel structure construction, and particularly discloses a flying-wing-type formwork space truss structure and a construction method thereof. The flying-wing-type formwork space truss structure comprises main trusses, auxiliary trusses and parallel chord member trusses. The main trusses, the auxiliary trusses and the parallel chord member trusses are welded and fixedly connected to form a formwork space truss structure body. The flying-wing-type formwork space truss structure further comprises flying-wing-type trusses located above the formwork space truss structure body. The flying-wing-type trusses are connected with the auxiliary trusses of the formwork space truss structure body through draglines. The invention further discloses the construction method of the flying-wing-type formwork space truss structure. The construction method includes the construction steps of support installing, main truss installing, hemisphere auxiliary truss installing, steel dragline constructing and the like. By means of the flying-wing-type formwork space truss structure, a whole structure is more stable, a chain block and a wall pulley are matched to carry out steel structure installing and steel dragline tensioning, the construction method is simple, the number of adopted machines is small, the site safety is guaranteed, the construction quality is also guaranteed, and the construction cost is greatly reduced.

Description

technical field [0001] The invention belongs to the field of steel structure construction, in particular to a flying airfoil formwork space truss structure and a construction method thereof. Background technique [0002] Steel structure has the advantages of high strength, light weight, fast construction speed, good seismic performance, energy saving and environmental protection, and high degree of industrialization, so it has become one of the key promotion projects in my country, and the corresponding steel cables have also been obtained in large-span space trusses. a wide range of applications. [0003] With the continuous progress of society and people's requirements for functional buildings are getting higher and higher, not only requires public buildings to have a beautiful appearance, but also to meet the use of functions, safety and stability, ordinary rigid structure and construction methods can no longer Meet the needs of engineering construction.
