Abstract

The invention belongs to the technical field of prefabricated reinforced concrete structures, and particularly relates to a reinforced concrete prefabricated part. The reinforced concrete prefabricated part comprises a board body, the board body is internally provided with a group of splicing units, an anti-seepage unit and an anti-corrosion unit; the board body is arranged in a reverse L shape; the group of splicing units are arranged on the side face of the board body, and the splicing units are used for splicing adjacent board bodies; the anti-seepage unit is arranged on the sides, in the board body, of the splicing units, and used for preventing seawater from penetrating into the board body; the anti-corrosion unit is arranged on the side, away from the splicing units, of the anti-seepage unit, and used for preventing the seawater from corroding reinforcements in reinforced concrete; and the splicing units, the anti-seepage unit and the anti-corrosion unit are matched with each other to prevent the seawater from penetrating through the board body and entering a foundation pit, and meanwhile, corrosion of the seawater on the concrete and the reinforcements is avoided, and normalworking of the board body is ensured.

Description

technical field [0001] The invention belongs to the technical field of prefabricated reinforced concrete structures, in particular to a reinforced concrete prefabricated part. Background technique [0002] In the construction process of cast-in-place reinforced concrete structures, there are many on-site fabrications, many wet operations, and a large number of intermediate links such as formwork projects and scaffolding projects, which waste resources and pollute the environment; issues of performance, quality and durability. To change the status quo, we should vigorously develop prefabricated concrete structures, reduce the amount of on-site concrete structures, and increase the rate of prefabrication. The main structural components of prefabricated concrete structures are manufactured in factories, which have high production efficiency and good quality, save resources and energy, and are conducive to sustainable development. The use of prefabricated concrete structures i...
