Abstract

The invention discloses a high-strength building waste regeneration concrete composite beam and a construction method thereof. A high-strength building waste regeneration concrete composite beam body comprises a high-strength regeneration aggregate concrete prefabricated groove, cast-in-place regeneration block body concrete filled in the high-strength regeneration aggregate concrete prefabricated groove, a plurality of longitudinal bars arranged on a high-strength building waste regeneration aggregate concrete composite beam in the beam-length direction, a plurality of closed stirrups vertically arranged in the groove-length direction and bottom plate steel nails. According to the high-strength building waste regeneration concrete composite beam and the construction method thereof, overall manufacturing is convenient and quick, and the economic benefits are high; according to design of the bottom plate steel nails, adhering between the high-strength regeneration aggregate concrete prefabricated groove and the cast-in-place regeneration block body concrete can be tighter, integrality of the beam is improved, the bearing capacity of the structure is effectively improved, and the deformation property of the beam is improved; and ductility of components is increased, and the high-strength building waste regeneration concrete composite beam and the construction method thereof are applicable to beam structures such as heavy loads, industrial factory buildings, high-rise buildings and the large spans.

Description

technical field [0001] The invention relates to the technical field of civil engineering, and specifically relates to a high-strength construction waste recycled concrete composite beam using construction waste recycled block concrete as a filling material. Background technique [0002] The amount of waste commercial concrete discharged after demolition and reconstruction in my country's construction industry is huge, which not only brings serious environmental and social problems, occupies increasingly tense land resources in urban construction, but also increases the production cost of construction products. In the face of increasingly serious environmental pollution, increasingly tense land supply, and increasingly depleted mineral resources, it is imperative to carry out comprehensive utilization of construction waste. The waste concrete in the construction waste is crushed and used as recycled aggregates to manufacture components in the building structure, which can sol...
