Embodiment

[0040] A prefabricated staircase, such as figure 1 , figure 2 As shown, a prefabricated staircase 1 and two installation platforms 2 are provided. 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. The end of each installation plate 3 away from the prefabricated stairs 1 is fixed with a number of second ribs 4, each second rib 4 is formed by two vertically distributed steel bars, and the second ribs 4 move away from the installation plate 3 along the horizontal direction direction extension. The lower end surface of each mounting plate 3 is also provided with several notches 5 , and each notch 5 is provided through the mounting plate 3 along the vertical direction. The notches 5 are located at the end of the mounting plate 3 away fro...

Abstract

The invention discloses an assembled staircase, which relates to the technical field of construction engineering. It comprises a prefabricated staircase and two installation platforms. The upper and lower ends of the prefabricated staircase are respectively provided with installation plates, and the upper end surface of the installation platform is correspondingly provided with a mounting plate. The embedded installation groove also includes: an accommodating groove, which is opened on the upper end surface of each installation platform and is located on the side of the installation groove away from the prefabricated stairs, and the accommodating groove is communicated with the installation groove; the first rib, The first rib is located at the side wall of the receiving groove facing the installation groove; the second rib is located at the end of the installation plate away from the prefabricated stairs, when the installation plate is located in the installation groove, the second The inserting ribs are located in the corresponding receiving grooves and are staggered from the first inserting ribs. By arranging the receiving groove, the first inserting rib and the second inserting rib, and injecting cement mortar into the receiving groove for fixing, the connection structure of the assembled staircase is stronger, and the overall use is safer and more durable.

Description

technical field [0001] The invention relates to the technical field of architectural engineering, more specifically, it relates to an assembled staircase. Background technique [0002] As the main vertical traffic of the building and the main channel for emergency evacuation, the stairs have an important impact on the normal use and emergency evacuation of the entire building. The prefabricated staircase is to prefabricate the staircase first, and then install it on site, making the construction of the staircase more efficient. [0003] For example, the Chinese invention patent whose patent number is CN110847525A discloses an assembled staircase that is easy to disassemble and assemble, including a base frame. A platform and a second platform, the top outer wall of the base frame is fixed with a plurality of equidistantly distributed step plates, and the base frame is fixed with positioning blocks corresponding to the step plates. During installation, the top plate and the...
