Description
Technical Field
The invention relates to the technical field of assembly type buildings, in particular to a safe anti-seismic suspended landscape stair structure.
Background
The stairs are building components for connecting spaces with different elevations in the building and are used for traffic connection between floors and when the height difference is large. Functionally, as a vertical transportation tool, the stairs closely link the floors together and are necessary components of the building, and whether the design of the stairs is reasonable or not has direct influence on the using effect of the building.
The design of stairs is needed to meet the requirements of traffic and evacuation on one hand, and on the other hand, abundant and variable building space is created by the aid of the stairs, and the stairs are designed as an artwork. In modern houses, in the design of stairs of duplex buildings, split floors, villas and multi-storey buildings, the home decoration style is more and more emphasized by people, the stairs are no longer simple vehicles for going up and down, and become a bright scenic spot in home decoration and a smart artwork in home. Therefore, many modern residences are provided with suspended landscape stairs, but most of the modern residences only address the appreciation and do not pay attention to the safety. In fact, the construction of stairs is closely related to the life safety of the user, and even if the decoration function is required, the safety of the stairs is ensured at first.
For example, patent document CN103628638B discloses a detachable hanging landscape staircase structure, which is composed of a hanging member, a stair step member, a platform member and a decorative guardrail member.

The external threads at the upper ends of the two suspenders on the same double-rod zigzag reverse spiral suspender are made into a structure with opposite spiral directions, after the nut is screwed down, the nut and the screw cannot loosen under the vibration generated by long-term use, and the loosening between the nut and the screw is either screw rotation or nut rotation, so that the screw cannot rotate due to the fact that the two screws are arranged on the same double-rod zigzag reverse spiral suspender; when the nut is rotated, because the spiral directions of the two screw rods are opposite, if the nut is rotated, the stress directions of the two nuts are necessarily the same, when one of the two nuts tends to be loosened, the other nut tends to be screwed, and thus the double-rod zigzag reverse spiral hanging rod cannot be loosened on the whole; in addition, the adopted double-rod basket-shaped reverse spiral suspender also prevents the screw and the nut from loosening.
And thirdly, the nut is locked in the nut sleeve hole of the locking disc by the nut locking disc, and the nut cannot rotate after the insertion block is inserted, so that loosening can be further prevented.
And a pedal nut is arranged to lock the tread plates at the bottoms of the suspension rods, so that the stability of the tread plates can be further improved.
No welding is carried out in the whole process, and no chemical permeation is adopted to be fastened in the floor slab or the floor, so that the installation and the disassembly are convenient.
Sixthly, integrally connecting the step plates end to end in a special structure formed by the double-rod zigzag reverse spiral hanger rod and the double-rod basket reverse spiral hanger rod to directly form a whole, wherein the screw and the nut cannot be loosened due to the double-rod reverse-rotation external threads of the same body, and the suspended landscape staircase has strong safety and anti-seismic performance integrally.
