Embodiment

[0040] A prefabricated staircase, such as figure 1 , figure 2 Shown, prefabricated stairs 1 and two installation platforms 2. The upper and lower ends of the prefabricated staircase 1 are respectively fixed with mounting plates 3, and the two mounting plates 3 are arranged in a square plate shape in a direction away from the prefabricated staircase 1, and the two mounting plates 3 are arranged parallel to each other. A number of second inserting ribs 4 are fixed at one end of each mounting plate 3 away from the prefabricated stairs 1, and each second inserting rib 4 is formed by two vertically distributed steel bars, and the second inserting ribs 4 face away from the mounting plate 3 in the horizontal direction. In the direction of extension. A number of notches 5 are also provided on the lower end surface of each mounting plate 3, and each notch 5 is provided through the mounting plate 3 in a vertical direction. The notches 5 are located at one end of the mounting board 3 aw...

Abstract

The invention discloses a prefabricated stair and relates to the technical field of construction engineering. The prefabricated stair comprises a prefabricated stair body and two mounting platforms; mounting plates are arranged at the upper and lower ends of the prefabricated stair body; mounting grooves allowing the mounting plates to be embedded are correspondingly formed in the upper end facesof the mounting platforms; the prefabricated stair further comprises accommodating grooves, first inserted reinforcements and second inserted reinforcements; the accommodating grooves are formed in the upper end faces of the mounting platforms, are positioned in the sides, far away from the prefabricated stair body, of the mounting grooves and communicate with the mounting grooves; the first inserted reinforcement are positioned on the side walls, towards the mounting grooves, of the accommodating grooves; the second inserted reinforcements are positioned at the ends, far away from the prefabricated stair body, of the mounting plates; and when the mounting plates are positioned in the mounting grooves, the second inserted reinforcements are positioned in the corresponding accommodating grooves and are staggered with the first inserted reinforcement. Through arranging the accommodating grooves, the first inserted reinforcements and the second inserted reinforcements, cement mortar is filled in the accommodating grooves for fixation, so that the prefabricated stair is stronger in connecting structure and safer and more durable in overall application.

Description

Technical field [0001] The invention relates to the technical field of construction engineering, and more specifically, it relates to a prefabricated staircase. Background technique [0002] As the main vertical traffic of the building and the main passage for emergency evacuation, the stairs have an important impact on the normal use and emergency evacuation of the entire building. The prefabricated stairs are to prefabricate the stairs first, and then install them on site, making the building's stairs more efficient. [0003] For example, the Chinese invention patent with the patent number CN110847525A discloses a prefabricated staircase that is easy to disassemble and assemble. It includes a base frame. The two ends of the base frame are respectively fixed with a top plate and a bottom plate. A platform and a second platform. The outer wall of the top of the base frame is fixed with a plurality of step plates distributed at equal distances, and the base frame is fixed with posi...
