When the spiral stair in this embodiment is connected fixedly, its top and first supporting beam 200 fixed connection, the bottom corresponds and second supporting beam 700 fixed connection, because stair body 100 is the spiral setting, make like this and be unsettled state in the middle of whole stair body 100, do not support and fix, when middle position bearing weight is great like this, then can produce and rock, security and stability are relatively poor, in this embodiment through set up a support column 140 structure in middle position department, then realized the support to whole stair body 100, four two effect of dialling very heavy have been realized, the unsettled problem in the middle of whole stair body 100 has been solved, be equal to and set up a support in the middle position department of stair body 100, and then whole stair's steadiness and security have been strengthened.
Meanwhile, only one support column 140 in the middle position is arranged in the embodiment, so that the support structure for the whole spiral staircase is reduced, the volume and the using amount of a column body to be adopted are greatly reduced, a plurality of support columns 140 are not required to be arranged for supporting, materials and manpower are saved, and the visual transparency and the attractiveness of the spiral staircase are ensured.
Further, in order to ensure the aesthetic property of the whole spiral staircase, the spiral staircase in this embodiment is further provided with a decorative layer 950, and the decorative layer 950 covers the fifth embedded part 820 and is arranged to be attached to the periphery of the main support keel 110.
Similarly, a decoration layer 950 can be disposed above the third embedded parts 330 and the third supporting parts 430.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
