Steel structural staircase for multi-storey industrialized house

Abstract

The invention discloses a steel structural staircase for a multi-storey industrialized house and belongs to the field of building structures. The steel structural staircase for the multi-storey industrialized house comprises integrated steel structural staircase stair flights, a main structure steel beam, high-strength bolts, a steel staircase foundation, a staircase embedded part and a staircase connecting part, wherein the bottom part of the integrated steel structural staircase stair flight on the bottommost layer is connected with the staircase embedded part on the steel staircase foundation by the staircase connecting part; the bottom parts of the rest of the integrated steel structural staircase stair flights are connected with the main structure steel beam by the high-strength bolts; the top parts of all the integrated steel structural staircase stair flights are connected and fixed with the main structure steel beam by the high-strength bolts. The steel structural staircase for the multi-storey industrialized house of the invention is simply and reliably connected with a main structure, is easy to install and position, is rapid and convenient to construct and install, has attractive appearance and has high integrity and comfort.

Description

technical field [0001] The invention relates to an industrialized steel structure staircase designed according to the industrialized housing system, manufactured in a factory and installed on site, and belongs to the field of building structures. Background technique [0002] At present, the stair structure of domestic residences mainly adopts two types: traditional reinforced concrete cast-in-situ stair and common steel structure stair. Traditional reinforced concrete stairs require on-site mold making and on-site concrete pouring, which takes a long time to maintain, which is not conducive to large-scale industrial production and installation. Compared with concrete stairs, ordinary steel structure stairs have many advantages, but there are still some deficiencies in the current design and construction. The main problems are as follows: 1. Ordinary steel structure stairs are generally processed separately by stair steel beams and tread plates. On-site welding into a whole...

AI Technical Summary

Problems solved by technology

Traditional reinforced concrete stairs require on-site mold making and on-site concrete pouring. The maintenance time is relatively long, which is not conducive to large-scale industrial production and installation.

Compared with concrete stairs, ordinary steel structure stairs have many advantages, but there are still some deficiencies in the current design and construction. The main problems are as follows: 1. Ordinary steel structure stairs are generally processed separately by stair steel beams and tread plates. On-site welding into a whole, so not only the on-site installation is more troublesome but also the integrity of the stairs is relatively poor; 2. Ordinary steel structure stairs are mostly connected to the main structure by welding, and the degree of rapid assembly on site is relatively poor; 3. Comparison of ordinary steel structure installation and positioning Poor, there is no installation bolt hole designed for easy construction; 4. The vibration of ordinary steel structure stairs is relatively large, and the comfort is relatively poor when used in residential buildings; 5. If ordinary steel structure stairs need to increase the integrity of the stairs, concrete should be poured twice on the steps When the design does not consider the corresponding structural measures, it is difficult to guarantee the pouring quality
