Description

Technical Field

[0001] The utility model relates to the technical field of building stairs, in particular to a multi-curved special-shaped twisted steel structure staircase. Background Art

[0002] The architectural form puts forward higher requirements for the fabrication and construction of steel structures. Especially for high-class office buildings, public exhibition centers, leisure and entertainment centers, etc., spiral staircases are often encountered. Among them, the steel structure spiral staircase is light in structure and strong in streamline, which can better show a brisk atmosphere and is favored by the majority of users. Usually, for the steel structure staircase fabricated by traditional technology, since the H-shaped steel is bent and twisted horizontally, it will cause the upper and lower bottom steels to bend upward and downward, resulting in the deformation of the H-shaped steel and failing to meet the use and force requirements, thus affecting the stability of the steel structure staircase.

[0003] The prior art CN21253391U discloses a fully suspended multi-curved special-shaped twisted steel structure staircase, which includes a stone veneer layer, a tread steel plate, an outer beam, an intermediate beam, an inner beam and a staircase surface. The outer surface of the galvanized steel plate cover layer is provided with a stone veneer layer; the tread steel plate is welded and formed by 50 angle steels, without the need to use a relatively thick steel plate as in the traditional way, which is beneficial to reducing the self-weight of the tread steel plate. By setting the outer beam, the intermediate beam and the inner beam, fixed points are provided on the outer side, the inner side and the middle of the staircase surface, so that the entire staircase surface forms a whole with the three beams, achieving overall force. The entire steel structure staircase is designed in the shape of an H-shaped steel, and the steel does not deform and does not affect the force structure of the profile, and can meet the overall force of the fully suspended large-arc staircase.

[0004] During normal use, when the steel structure staircase of the prior art is located at a high altitude, the steel structure staircase is prone to shaking in the air, which affects the safety of the steel structure staircase at a high altitude and thus affects the stability of the steel structure staircase. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a multi-curved special-shaped twisted steel structure staircase, which solves the problem that when the steel structure staircase of the prior art is located at a high altitude, the steel structure staircase is prone to shaking in the air, which affects the safety of the steel structure staircase at a high altitude and thus affects the stability of the steel structure staircase.

[0006] To achieve the above object, the present utility model provides a multi-curved special-shaped torsion-bent steel structure staircase, including a staircase body and a structural component; the structural component includes a connecting piece, a seat body, a steel rope, a buckle seat, a swivel buckle, a rod body, a block, a first shaft rod, a second shaft rod and a fixing nut. The connecting piece is fixedly installed on one side of the staircase body. The first shaft rod is rotatably installed on the side of the connecting piece away from the staircase body. The buckle seat is fixedly connected to the first shaft rod and rotatably connected to the connecting piece. The rod body is fixedly installed on the side of the buckle seat away from the first shaft rod. The block is threadedly connected to the rod body. The fixing nut is threadedly connected to the rod body and abuts against the block. The steel rope is fixedly installed on the side of the block away from the buckle seat. The swivel buckle is fixedly installed on the side of the steel rope away from the block. The second shaft rod is fixedly installed on the side of the swivel buckle away from the steel rope. The seat body is rotatably connected to the second shaft rod and rotatably connected to the swivel buckle.

[0007] Wherein, the rod body has an external thread, and the external thread is located on the side of the rod body close to the fixing nut and cooperates with the fixing nut.

[0008] Wherein, the connecting piece has a rotating hole, and the rotating hole is located on the side of the connecting piece close to the first shaft rod and cooperates with the first shaft rod.

[0009] Wherein, the seat body has a through hole, and the through hole is located on the side of the seat body close to the second shaft rod and cooperates with the second shaft rod.

[0010] Wherein, the structural component further includes a fixing block, a cushion, a fixing screw and a fixing seat.
