Abstract

A hanging steel stair connecting structure belongs to the technical field of steel stairs designed by building structures and steel structures. The steel ladder beam comprises a steel ladder beam, a platform beam, a vertical suspender, a high-strength bolt, a base plate, a nut and a stiffening plate; the steel ladder beam is hinged with the platform beam through a high-strength bolt; the upper flange and the lower flange of the platform beam are provided with holes, the vertical suspender passes through the platform beam, and the holes of the platform beam are provided with backing plates (an upper backing plate and a lower backing plate) which are welded with the platform beam; the platform beam is a box-shaped steel beam, and stiffening plates are welded on two sides of the corresponding vertical suspender. And (4) threading and adding a nut below the vertical suspender, and welding after screwing. The advantage lies in, when having solved steel stair can not found the post, the connection support problem of steel ladder roof beam.

Description

Hang steel stair connection structure

Technical Field

The utility model belongs to the technical field of steel stairs designed by building structures and steel structures, and particularly relates to a connecting structure of a hanging steel stair.

Background

At present, national economic level of China is greatly improved, the building industry is developed rapidly, steel structures are more applied to large-scale places such as airports, railway stations, stadiums, natatoriums and the like, in recent years, the rapid development of building technologies and building materials, building aesthetics, simple humanization and innovative thinking are increasingly concerned by people, under the guidance of the new thinking, steel structure stairs with attractive and personalized appearance are arranged in many domestic buildings, the shape of the special-shaped steel stairs is developed towards the direction of large span and fiber refinement while the dead weight of the buildings is reduced, and therefore convenience and new experience are provided for life of people.

Along with the building form diversification day by day, in order to satisfy building function and pleasing to the eye demand, more and more architectural design favours the novel molding and the no post space utilization of hanging steel stair, will hang steel stair wide application in the actual engineering. How to realize effective and reliable biography power route of steel stair, guarantee the safety of steel stair structure is the technical problem that technical staff urgently awaits solution in engineering field at present.

Disclosure of Invention

The utility model aims to provide a connecting structure for a hanging steel stair, which solves the problem of connecting and supporting steel stair beams when a steel stair cannot stand a pillar.

The steel ladder beam comprises a steel ladder beam 1, a platform beam 2, a vertical suspender 3, a high-strength bolt 4, a backing plate 5, a nut 6 and a stiffening plate 7; the steel ladder beam 1 is hinged with the platform beam 2 through a high-strength bolt 4; the upper flange and the lower flange of the platform beam 2 are both provided with holes, the vertical suspender 3 penetrates through the platform beam 2, and the holes of the platform beam 2 are provided with backing plates 5 (one for each of the upper flange and the lower flange) which are welded with the platform beam 2; the platform beam 2 is a box-shaped steel beam, and stiffening plates 7 are welded on two sides corresponding to the vertical suspender 3. And a nut 6 is sleeved on the lower surface of the vertical suspender 3 and welded after being screwed down.
