Prefabricated reinforced concrete beam with transverse steel partition boards and construction method

Abstract

The invention relates to a prefabricated reinforced concrete beam with transverse steel partition boards. By adopting the idea of partial prefabrication and partial cast-in-situ, the prefabricated reinforced concrete beam is composed of a prefabrication part and a cast-in-situ part, and specifically includes: a precast U-shaped high-strength concrete groove; cast-in-situ common concrete 1 filling the precast U-shaped high-strength concrete groove; several transverse steel partition boards that are disposed in the precast U-shaped high-strength concrete groove and are perpendicular to the groove length direction; several closed stirrups that are disposed in the precast U-shaped high-strength concrete groove and are perpendicular to the groove length direction; several longitudinal bars 1 that are disposed at the bottom of the precast U-shaped high-strength concrete groove and are parallel to the groove length direction; and a cast-in-situ frange plate disposed at the top of the precast U-shaped high-strength concrete groove. The invention also provides a construction method of the beam. The construction method provided by the invention can improve the longitudinal anti-shearing effect between precast concrete and cast-in-place concrete, at the same time prevents lateral damage, and improves the crack resistance, durability and fire resistance of the beam.

Description

technical field [0001] The invention belongs to the technical field of construction, in particular to a prefabricated and assembled reinforced concrete beam with a transverse steel 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-friendly soci...

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
