Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stairs, in particular to an assembled double-beam steel structure stacked staircase. Background Art
[0002] With the popularity of light luxury minimalist decoration style, floating stairs are more and more widely used in home decoration. Floating stairs have a light and simple effect, but traditional floating stairs have various serious problems in structural stress, construction, safety, etc., and the floating effect of stairs cannot be achieved when there is no wall at the stair opening.
[0003] In the prior art, the traditional household suspended staircase has the following defects during the manufacturing process: (1) On-site wall grooving: it destroys the original wall's load-bearing and structure, increases safety hazards, and increases the amount of on-site construction; (2) On-site welding construction: welding construction personnel basically do not have welding certificates and lack safety protection. There are serious safety hazards and the workload of on-site production is large; (3) There is no standard for structural design; (4) There are serious risks in the load-bearing of stair treads; (5) The steel structure cannot be treated with anti-corrosion on site: anti-corrosion treatment is mainly divided into thorough rust removal and adding a protective layer to the surface of the steel structure. It is impossible to completely remove rust on the construction site, and the surface protective layer is limited to manual anti-rust paint, which does not play any anti-corrosion role and may rot in the later stage, affecting the load-bearing safety. Utility Model Content
[0004] The utility model aims to solve many defects existing in traditional suspended stairs, thereby providing an assembled double-beam steel structure stacked suspended staircase.
[0005] The technical solution adopted by the utility model is: it includes two side base members and a plurality of step assemblies located between the two side base members, the side base member includes a connecting steel plate beam connected to the step assembly, the connecting steel plate beam is provided with an outer steel plate beam on the side away from the step assembly, and the connecting steel plate beam and the outer steel plate beam are fixedly connected by multiple groups of reinforcing steel plates and glass railing support plates.
[0006] As a further improvement of the utility model, a plurality of pre-installation holes are provided on the outer steel plate beam.
[0007] As a further improvement of the present invention, the reinforcing steel plate is combined with the glass railing support plate to form a triangular structure.
[0008] As a further improvement of the utility model, the step assembly consists of an upper pedal, two side steel plates, and three rectangular steel tubes. The two side steel plates are fixedly connected by three rectangular steel tubes, and the upper pedal is located on the top of the two side steel plates and the three rectangular steel tubes and is fixedly connected thereto.
[0009] As a further improvement of the utility model, the side steel plate is fastened to the connecting steel plate beam on the same side thereof by bolts, and the side steel plate and the connecting steel plate beam are both provided with connecting holes connected by bolts.
[0010] As a further improvement of the utility model, a plurality of construction holes are provided on the upper pedal and the construction holes are located above the bolts.
[0011] Compared with the traditional suspended staircase, the utility model has the following beneficial effects:
[0012] (1) The side foundation members do not need to rely on the wall to bear the force: the connecting steel plate beam and the outer steel plate beam are welded and manufactured in the factory. High-strength bolts are used to fix the on-site ground, turning walls, and floor cement beams. In the case of a partial lack of walls, the beam itself can bear the force.
[0013] (2) The installation of the step assembly does not require on-site welding: during installation, only high-strength bolts are required to directly fix the step assembly to the connecting steel plate beam.
[0014] (3) Steel structure has strong anti-corrosion performance: by adopting the assembly method, all steel components can be shot blasted in the factory to remove rust and electrostatically sprayed to achieve anti-corrosion effect.
[0015] (4) Save on-site construction time: All processes can be completed at one time, reducing safety hazards during on-site construction. BRIEF DESCRIPTION OF THE DRAWINGS
