Description
Technical Field
[0001] This utility model relates to the field of spiral staircase technology, and more specifically, to an outdoor spiral staircase with a surrounding structure. Background Technology
[0002] Spiral staircases, also known as spiral staircases or spiral staircases, are a unique staircase design characterized by their continuous rotation and ascent around a central point or axis. This design not only saves space but also adds an elegant and dynamic aesthetic to architecture. Spiral staircases are commonly found in modern residences, commercial spaces, museums, art galleries, and some historic buildings. The design of spiral staircases significantly reduces the horizontal area occupied by the staircase, making them particularly suitable for spaces with limited space but a desire to create a sense of height. The spiraling, ascending form gives a feeling of flow and upward movement, increasing the sense of layering and dynamism in the space, making it a highlight in architectural design. Spiral staircases can be customized to suit different space sizes and styles, from minimalist modern to classic luxury, each finding a suitable expression. Due to the continuous rotation of the staircase, it visually guides people's gaze upward, enhancing the verticality and depth of the space. With its unique aesthetic appeal and space-saving advantages, spiral staircases have been widely used in modern architectural design.
[0003] Currently, spiral staircases have poor stability, and users can clearly feel vibrations during use, posing certain safety hazards.
[0004] This invention can provide high stability. Utility Model Content
[0005] The present invention aims to solve the technical problems mentioned in the background art and provide an outdoor spiral staircase with a surrounding structure.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an outdoor spiral staircase with a surrounding structure, comprising: several steps, each step being fan-shaped, with a cylinder extending from the left front end of the bottom surface of the step, the bottom surface of the cylinder of the step being connected to the top surface of another step, and the outer side of the step being detachably connected to the inner side of the surrounding structure with screws and nuts.
[0007] The edging is in the shape of a spiral long plate, and screws are welded to the side of the edging near the step;
[0008] Several of the inner side surfaces of the steps are spirally distributed and sequentially welded around the side of the support column from top to bottom. The support column is a tall cylindrical shape, with a second handrail welded to the top surface of the support column, and a gate is movably installed on the lower side surface of the support column via a hinge.
[0009] A further preferred embodiment: A first handrail post is welded to the top surface of the step. The first handrail post includes two first rectangular plates in a group. The surface of the first rectangular plate has five holes, each of which is welded with a first cylinder. A first fence tube passes through the middle of the four first cylindrical surfaces from bottom to top of the first handrail post. A bolt lock is welded to one end of the third first fence tube from bottom to top.
[0010] A further preferred embodiment: a first handrail is welded to the upper end of the first handrail post, and one end of the first handrail is welded to the top surface of the second handrail post.
[0011] A further preferred embodiment: The second handrail post includes two sets of second rectangular plates, with a second cylinder welded through the surface of the second rectangular plate. A second fence tube is inserted through the middle of the four second cylindrical surfaces of the second handrail post from bottom to top. The bottom surface of the second handrail post is welded to the left and right sides of the top surface of the support plate.
[0012] A further preferred embodiment: The top of the second handrail column at the right end is fixedly connected to the second handrail.
[0013] A further preferred embodiment: the side of the step is detachably fitted with a rim by screws and nuts, and several screws are welded to the plate on the side of the rim facing the support column and connected to the side of the step.
[0014] A further preferred embodiment: the first fence tubes are arranged in groups of four to six.
[0015] Beneficial effects:
[0016] 1. By incorporating a perimeter and steps, the perimeter installed at the lower outer side of the spiral staircase distributes the force of each step outwards to other areas, making the staircase more stable during use, less prone to deformation due to excessive force, extending its lifespan, and improving safety. When multiple people use the spiral staircase simultaneously, the perimeter distributes the force to the remaining components, ensuring even stress distribution and preventing wobbling. The perimeter is secured to the steps with screws welded to its edge, which pass through holes in the steps and are fixed with nuts, making the perimeter removable. If the perimeter deforms or becomes damaged after prolonged use, only the perimeter needs to be disassembled and replaced, rather than replacing the entire staircase.
[0017] 2. By installing a gate and a bolt lock, the administrator can restrict access. When the spiral staircase is not open or is under maintenance, the gate can be locked with the bolt lock to prevent unauthorized personnel from using it. Attached Figure Description
