An Assembled Coupling Beam with Built-in Profiled Steel Groove Structure

Abstract

The invention discloses an assembled coupling beam with a built-in profiled steel sheet groove structure and belongs to the technical field of an assembled concrete structure. The assembled coupling beam consists of coupling beam longitudinal bars, coupling beam hooping bars, coupling beam concrete, corrugated steel plates, profiled steel sheets, profiled steel sheet connecting rods and toggle pins. Groove structures are formed at the two ends of a prefabricated coupling beam by arranging the profiled steel sheets with the toggle pins serving as inner formwork at the two ends of an assembled concrete prefabricated coupling beam component, a beam nest and the parts enclosed by grooves are cast in situ, and a detachable splicing system which is more simple and easy to construct is formed at a beam end, so that work quantity of field templates can be reduced, and construction difficulty is reduced. Cooperative work between the profiled steel sheets and the concrete can be ensured by the toggle pins arranged on the profiled steel sheet, strong connection between the coupling beam and a shear wall slab is realized through the profiled steel sheets and connecting components of the profiled steel sheets, wide coupling beam advantage is exerted, depth-span ratio is reduced while bending rigidity of the coupling beam is ensured, and the integrality and energy consumption ability of the structure are further improved.

Description

technical field [0001] The invention belongs to the technical field of assembled concrete structures, and in particular relates to an assembled connecting beam with a built-in profiled steel plate groove structure. Background technique [0002] The coupling beam is an important component in the building structure. The shear wall connects the wall piers together through the coupling beam to make them deform in a coordinated manner and form an overall lateral force-resistant structure. In the prefabricated concrete shear wall structure, since the coupling beam is mainly constructed by the all-in-situ construction method, or the method of lapping the fully prefabricated coupling beam on the reserved beam socket of the shear wall and then casting in-situ When the all-cast-in-place construction method is adopted, the concrete wet work on site will be very large; the formwork support and formwork removal workload during the construction of multi-coupling beams or coupling beam str...

Problems solved by technology

[0004] The object of the present invention is to propose an assembled coupling beam with a built-in profiled steel plate groove structure in view of the problems existing in the prior art. The profiled steel plate is arranged at the beam end to form a “groove structure” to ensure that the coupling beam and shear The strong connection between the force wall panels; increasing the width of the connecting beam and arranging corrugated steel plates can meet the structural requirements and facilitate installation, while effectively increasing the shear area of ​​the connecting beams, giving full play to the shear resistance and energy dissipation capabilities of the corrugated steel plates, and solving the problem of connecting beams. Insufficient shear bearing capacity and poor ductility of beams, etc., reduce the amount of formwork work on site, and facilitate the construction of single and multi-connected beam structures
