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