Prefabricated reinforced concrete beam with transverse high-strength concrete separation plate and construction method thereof

Abstract

A prefabricated reinforced concrete beam with a transverse high-strength concrete separation plate employs an idea of casting a part of a prefabricated part in situ, and is composed of a prefabricated part and a cast-in-situ part, and comprises a prefabricated U-shaped high-strength concrete groove, first in-situ common concrete packed into the prefabricated U-shaped high-strength concrete groove, multiple transverse high-strength concrete separation plates which are arranged in the prefabricated U-shaped high-strength concrete groove and are perpendicular to the groove length direction, multiple closed stirrups which are arranged in the prefabricated U-shaped high-strength concrete groove and are perpendicular to the groove length direction, multiple first longitudinal ribs which are arranged in at the bottom of the prefabricated U-shaped high-strength concrete groove and are parallel to the groove length direction, and a cast-in-situ flange plate arranged at the top of the prefabricated U-shaped high-strength concrete groove. The invention also provides a construction method for the beam. According to the technical scheme, the longitudinal anti-shearing effect between the prefabricated concrete and cast-in-situ concrete is improved, and also lateral destroying is prevented, and the crack resistance, durability and fireproof performance of the beam are improved.

Description

technical field [0001] The invention belongs to the technical field of buildings, in particular to a prefabricated and assembled reinforced concrete beam with a transverse high-strength concrete partition and a construction method. Background technique [0002] In the modern reinforced concrete structure, the earliest and most widely used structural form is the cast-in-place reinforced concrete structure, which is a structure formed by setting up formwork on site and integrally pouring, and has the advantages of good overall performance, high rigidity, and good seepage resistance. , At the same time, it is also highly adaptable to buildings with irregular shapes and flexible spaces. However, there are also many disadvantages in the process of use, such as on-site formwork and construction, many construction procedures, a large amount of labor, a large amount of materials, a long cycle, and high costs, which have not played a role in creating a resource-saving and environment...

AI Technical Summary

Problems solved by technology

Compared with the cast-in-place concrete structure, the prefabricated structure can make the production of building components not affected and restricted by seasons, and realize industrial production. Since the components are poured and maintained in the factory, the quality of the components can be guaranteed, and the construction period is greatly shortened. Accelerate the construction progress and save a lot of formwork support, but it also has many shortcomings, such as poor overall performance, poor impermeability, unfavorable earthquake resistance, and certain deficiencies in use and aesthetics
