Cast-in-place reinforced concrete haunched beam structure

Abstract

The invention discloses a cast-in-place reinforced concrete haunched beam structure. The cast-in-place reinforced concrete haunched beam structure comprises a plurality of perpendicularly arranged frame columns, the tops of the frame columns are horizontally connected through frame beams, beam supporting seat haunched areas are arranged on the portions, where the frame columns and the frame beams are connected, of a cast-in-place reinforced concrete beam supporting seat, inclined rebars are arranged in the haunched areas, and the inclined rebars and rebars on the lower portions of beam midspan rebars are anchored mutually. Because the portions of the beam supporting seat are haunched, the height of the cross section of the supporting seat is increased, and reinforcing bars for the portions of the beam supporting seat are reduced under the action of the hogging moment; on the premise that internal force calculation is met, on the one hand, the using amount of concrete is effectively reduced, and the self weight of the structure is reduced, and on the other hand, the form of the cross section of the beam fits into an internal force graphic, the functions of the rebars on all the portions are fully played, and the long-span structure achieves the purposes of being light, attractive, economical and reasonable; moreover, the midspan height of the beam is relatively small, and thus the cast-in-place reinforced concrete haunched beam structure is favorable for layout of pipelines, and the clear height of a building room is increased.

Description

[0001] technical field [0002] The invention relates to a cast-in-place reinforced concrete plus haunch beam structure, which belongs to the technical field of reinforced concrete structure design and construction. Background technique [0003] The cast-in-place reinforced concrete structure has a wide range of applications, and the cast-in-place reinforced concrete beam is one of the most important components in the structure. Under normal circumstances, reinforced concrete beams are often of equal height. When the span is large or the load is large, the problem is generally solved by increasing the beam height. When using conventional methods to calculate and design equal-height beams, the beam height is larger, the overall structural materials and self-weight increase, and the cost also increases accordingly. At present, research on the application of haunched beams in transfer beams has been relatively sufficient, and some experimental research results show that: frame...
