Anchoring-type prefabricated staircase connecting structure

Abstract

The invention discloses an anchoring-type prefabricated staircase connecting structure which comprises a prefabricated staircase, a lower-end laminating platform and an upper-end laminating platform.The lower-end laminating platform and the upper-end laminating platform each comprise a prefabricated layer and a cast-in-place layer, and an upper cantilever lug and a lower cantilever lug are arranged at the upper end and the lower end of the prefabricated staircase correspondingly. The upper cantilever lug is overlapped at the end of the prefabricated layer of the upper-end laminating platform,and the lower cantilever lug is overlapped at the end of the prefabricated layer of the lower-end laminating platform. Upper reserved double-row steel bars are anchored in the cast-in-place layer ofthe upper-end laminating platform, and lower reserved double-row steel bars are anchored in the cast-in-place layer of the lower-end laminating platform. The disadvantages that an existing prefabricated staircase is poor in integrity, small in stiffness and poor in seismic resistance are overcome, the connection strength between the prefabricated staircase section and the staircase platforms is improved, the integrity of the staircase is reinforced, and the requirement of industrialized production is met.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an anchored prefabricated staircase connection structure. Background technique [0002] With the development and requirements of building energy conservation and emission reduction and housing industrialization, the country has begun to vigorously promote prefabricated buildings. As an important part of it, the prefabricated staircase has also been vigorously developed. Stairs, as the main vertical traffic of the building and the main channel for emergency evacuation, have an important impact on the normal use and emergency evacuation of the entire building. The assembly of stairs is also one of the main indicators of the assembly rate of prefabricated buildings. [0003] Traditional stairs generally use on-site formwork, workers manually bind the steel bars, and pour them into shape at one time, so they have the characteristics of good integrity, high rigidity,...

AI Technical Summary

Problems solved by technology

However, the traditional cast-in-place staircase has cumbersome procedures, is greatly affected by external factors, and is prone to quality problems

The existing prefabricated stairs are generally prefabricated in factories and installed on site. Although the process is simplified, due to the use of lap joints, the integrity is poor, the rigidity is small, and the shock resistance is poor. Therefore, a cast-in-place staircase with the advantages of assembled monolithic staircase
