Overlapped reinforced concrete plate structure capable of bearing heavy load, and manufacturing method

Abstract

The invention discloses an overlapped reinforced concrete plate structure capable of bearing heavy load. A cover beam is hoisted with and is fixedly provided with a track beam through a joint. The upper end of the track beam is provided with an edge bottom layer precast slab in which lattice ribs are buried, a first inter-beam bottom layer precast slab, and a second inter-beam bottom layer precast slab. Lower surfaces of the edge bottom layer precast slab, the first inter-beam bottom layer precast slab, and the second inter-beam bottom layer precast slab are provided with longitudinal constructional reinforcements, cross-bridge direction load-bearing bars, and lower bars, and upper surfaces are poured with cast-in-place slabs. The manufacturing method for the overlapped reinforced concrete plate structure capable of bearing heavy load comprises the following process: after the cover beam construction and manufacturing is completed, hoisting a prefabricated concrete track beam to a given position of the cover beam, hoisting the precast slabs which is buried with lattice ribs to installation points on the track beam, and jointing and fixing rebar deposit concrete on the precast slabs to form cast-in-place slabs.

Description

technical field [0001] The invention belongs to the field of civil engineering, and in particular relates to a superimposed reinforced concrete slab structure capable of bearing heavy loads and a manufacturing method thereof. Background technique [0002] Concrete bridge deck structure or floor slab structure, when the cast-in-place slab structure is simply used, the overall performance of the structure is better, but the construction period is longer, the on-site construction is more difficult, the human resources are high, and the amount of formwork is larger, which increases the construction cost accordingly . [0003] The prefabricated concrete slab structure is a structural form suitable for industrialization and can be manufactured in a factory, thereby shortening the on-site operation time. The joint connection structure between precast components in the precast concrete structure determines the overall performance of the structure, but the existing precast concrete ...

AI Technical Summary

Problems solved by technology

The joint connection structure between precast components in the precast concrete structure determines the overall performance of the structure, but the existing precast concrete structure joints are generally the weak link of the structure, which affects the mechanical performance, and the construction process is relatively complicated

[0004] Furthermore, for the concrete slab structure using prefabricated slabs, it is usually arranged on the frame beam or track beam, the integrity between the slab and the beam is poor, and the mutual force bearing capacity is weak
