Example Embodiment

[0097] Such as figure 1 A construction method of a spatial curved rib beam steel structure is shown. The constructed spatial curved rib beam steel structure includes multiple curved rib beams 1 arranged on a horizontal foundation from front to back, and multiple curved rib beams. The structure of 1 is the same, the curved rib beam 1 is a curved steel beam and its cross-sectional shape is a Japanese shape, see figure 2 ; Combine image 3 Each of the curved rib beams 1 is formed by splicing the outer beam body 1-1 and the inner beam body 1-2 located inside the outer beam body 1-1, the outer beam body 1-1 and the inner beam body 1-1 The tension beams 3 arranged from top to bottom between 1-2 are fastened and connected as a whole through M lanes. The tension beams 3 are linear steel beams; the outer beam body 1-1 and the inner beam body 1-2 The bottoms are supported on the horizontal foundation and the tops of the two are firmly connected as a whole; the multi-fold curved rib beams...

Abstract

The invention discloses a construction method for a space curved rib girder steel structure. The constructed space curved rib girder steel structure comprises several curved rib girders distributed on a horizontal foundation from front to back; the cross section of the curved rib girders is H-shaped and its outer girder body and inner girder body are formed by splicing M steel girder sections; several curved rib girders are integrally connected by interlayer ring beams; the steel girder section comprises an upper flange plate, a lower flange plate, two webs and a longitudinal stiffening plate; and each steel girder section is provided with a connecting base. The construction process of the space curved rib girder steel structure comprises the steps: firstly, curved rib girder factory processing, processing each steel girder section of the curved rib girder; secondly, curved rib girder conveying; thirdly, curved rib girder field splicing; and fourthly, curved rib girder and interlayer ring beam field installation. The process is simple, the design is rational, the construction is convenient, and the using effect is good. The construction process of the space curved rib girder steel structure can be simply and conveniently completed, the construction process is safe and the construction period is short.

Description

technical field [0001] The invention belongs to the technical field of steel structure building construction, and in particular relates to a construction method of a space curved rib beam steel structure. Background technique [0002] With the emergence of a large number of special-shaped buildings such as large spans and space torsion, steel structures have become a pioneer in replacing traditional reinforced concrete structures because of their light weight, high strength, industrial production, over 90% reusability, and good processability. The perfect choice for design. The modern steel structure system is becoming more and more complex and diverse, and the scale is also increasing. The complex steel structure formed by the combination of various structural systems has been widely used in modern buildings. [0003] Such as figure 2 The space curved rib beam steel structure shown, the overall appearance presents a radial center sunken rotary throw dome roof, the whole r...
