Abstract

The invention relates to a light assembly type stairway and a construction method thereof and relates to the field of building structures. The stairway comprises an oblique beam with a light concrete upper layer, wherein a plurality of steps are arranged on the upper oblique surface of the oblique beam, supporting parts used for connection are arranged at the upper end the lower end of the oblique beam respectively, thin-wall U-shaped steel is wrapped in each supporting part, the notches of the two pieces of thin-wall U-shaped steel are opposite, the upper portions and lower portions of the two pieces of thin-wall U-shaped steel are connected through electrowelding bar-mat reinforcements wrapped in the oblique beam respectively, inclined inserted steel bars are welded between the two electrowelding bar-mat reinforcements, and a bolt hole penetrating through the thin-wall U-shaped steel from top to bottom is formed in the supporting part at the upper end or lower end of the oblique beam. The stairway is compact in structure and light, and construction is convenient.

Description

technical field [0001] The invention relates to a lightweight assembled staircase and a construction method thereof, and relates to the field of building structures. Background technique [0002] Prefabricated buildings are already a trend in modern architecture, and the construction of each assembly component in a prefabricated building is particularly important, especially the stairs. The existing prefabricated stairs are made of ordinary concrete, which is not only heavy in weight, difficult to install, high in mechanical requirements, but also unfavorable in earthquake resistance. Therefore, a prefabricated lightweight staircase is needed. Contents of the invention [0003] The object of the present invention is to provide a light assembled staircase and its construction method. The staircase not only has a compact structure and light weight, but also has a convenient construction method. [0004] The technical solution of the present invention lies in: a lightweight ...
