Embodiment 1

[0021] figure 1 It is a schematic diagram of the structure of the cantilever system of the series tie rod arch type prestressed steel structure using the support diagonal brace in the embodiment of the present invention.

[0022] Such as figure 1 As shown, the arch-type prestressed steel structure cantilever system with tie rods in series has: L-shaped steel arch beam 1, arch inner support 2, arch back support 3, additional arch back support 4, force cable 5, stabilizing cable 6, support column 7 , Support diagonal support 8, force cable support 9, stable cable support 10 and base 11.

[0023] The L-shaped steel arch beam 1 adopts beam-type members or truss-type members such as H-shaped cross-section and box-shaped cross-section. The L-shaped steel arch beam 1 in this embodiment has: a side and a bottom, the two sides are connected to form an L shape, and the angle between the two sides should be between 90° and 120°. The number of L-shaped steel arch beams 1 can be two or ...

Embodiment 2

[0039] figure 2 It is a schematic diagram of the structure of the cantilever system of the series tie rod arch type prestressed steel structure using the support shear wall in the embodiment of the present invention.

[0040] Such as figure 2 As shown, in this embodiment, the support shear wall 12 is used instead of the support brace 8, and the structures and connection methods of the rest of the components are the same as those in the first embodiment.

[0041]The support shear wall 12 is arranged within the range surrounded by two adjacent support columns 7 , the bottom edge of the lowermost L-shaped steel arch beam 1 and the base 11 .

[0042] The support shear wall 12 is used to improve the shear resistance of the connection between the cantilever part of the structural system and the base 11, and walls including concrete shear walls and steel plate shear walls can be used. In this embodiment, the support shear wall 12 is a steel plate shear wall.

Abstract

The invention provides a series-tied-arch-type prestressed steel structure cantilever system. The series-tied-arch-type prestressed steel structure cantilever system is characterized by comprising a plurality of sequentially-connected L-shaped steel arched beams, in-arch supports, arch-back supports, stress cables, stable cables, a plurality of support stand columns and a base; the top end of each L-shaped steel arched beam is connected with the bottom end of the adjacent L-shaped steel arched beam located above the L-shaped steel arched beam; the in-arch supports are arranged on the inner sides of the L-shaped steel arched beams and connected with the top ends and the middles of the bottom edges of the L-shaped steel arched beams; the arch-back supports are arranged on the back sides of the L-shaped steel arched beams and connected with inflection points of the L-shaped steel arched beams and the middles of the bottom edges of the adjacent L-shaped steel arched beams located above the L-shaped steel arched beams; the stress tables are sequentially connected with the bottom ends of all the L-shaped steel arched beams, and the top ends of the stress stables can be connected with the top end of the uppermost L-shaped steel arched beam; the stable cables are sequentially connected with the outer sides of the inflection points of the L-shaped steel arched beams located above the lowest L-shaped steel arched beam; the top ends of the multiple support stand columns are connected with the bottom edge of the lowest L-shaped steel arched beam; the base is connected with the bottom ends of the support stand columns, and the bottom ends of the stress cables and the bottom ends of the stable cables are fixed to the support stand columns or the base.

Description

technical field [0001] The invention relates to a prestressed steel structure cantilever system in construction engineering, in particular to a series tie rod arch type prestressed steel structure cantilever system. Background technique [0002] Long cantilever or heavy-duty cantilever structures are limited in cantilever length and section height in order to meet their own bearing capacity and normal use requirements. [0003] Conventional beam-type and truss-type cantilever steel structures, due to the limitation of material strength and section height, when used in long cantilever and heavy-duty structures, if the cantilever length exceeds a certain value, the structure cannot meet the load-bearing capacity and deformation requirements. requirements. Contents of the invention [0004] The present invention is carried out in order to solve the above-mentioned problems, and the purpose is to provide a cantilever system of series tie-rod arch type prestressed steel struct...
