Description

Technical Field

[0001] This utility model relates to a steel spiral staircase structure. It is applicable to the field of staircase structure technology. Background Technology

[0002] With the continuous development of water conservancy infrastructure construction and the advancement of modernization, the maintenance and management of various hydraulic structures have become increasingly important, especially in the operation and management of water conservancy equipment such as intake gate rooms. Intake gate rooms are typically used for the operation and maintenance of water conservancy facilities such as sluice gates, reservoirs, and pumping stations. These rooms are usually equipped with gate hoists, electrical control systems, valves, pipelines, and other equipment. In actual operation, the functionality and safety of the gate room are paramount; therefore, all supporting facilities within the room must meet stringent requirements for safety, durability, and convenience.

[0003] In the design and construction of machine rooms, staircases are an important supporting facility, often used for staff mobility and equipment maintenance. While traditional steel staircase structures can meet certain needs, with technological advancements and the diversification of machine room usage requirements, existing traditional steel staircases have the following drawbacks: low space utilization: traditional solid columns occupy a large amount of machine room space and cannot integrate other functions; limited functionality: used only as a passageway, without considering the needs of cable routing within the machine room.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0019] Example 1 is a steel spiral staircase structure, which has the following features:

[0020] Column 1 is arranged between the first platform and the second platform. The first platform is located above the second platform. Column 1 is hollow and has a chamber 1-1 in the middle that allows pipelines to pass through.

[0021] Step 2 is spirally installed on column 1, and support column 4 is fixedly connected to the end of two adjacent steps 2 away from column 1.

[0022] The guardrail 3 is installed on the step 2 at the end away from the column 1. In this way, the pipeline between the first platform and the second platform can be connected through the chamber 1-1 of the column 1, and it is convenient for personnel to move between the first platform and the second platform via the step 2 on the column 1.

[0023] In this embodiment, reinforcing ribs 9 are installed inside chamber 1-1 of column 1. This gives column 1 higher structural strength.

[0024] Example 2 is a steel spiral staircase structure. Based on Example 1, in this example, at least two rest platforms are provided along the length of column 1. Each rest platform is connected to its two front and rear steps 2 at both ends, and the distance between two adjacent rest platforms is 6 meters. This allows people to rest at the rest platforms when the distance between the first and second platforms is relatively large.

[0025] A resting platform on column 1, adjacent to the first platform, is designated as the first resting platform 5. A resting platform on column 1, adjacent to the second platform, is designated as the second resting platform 6. Mounting holes 7 are formed on the side wall of column 1 at positions corresponding to the first resting platform 5 and the second resting platform 6. These holes allow the first end of the pipeline inside column 1 to extend from the mounting hole 7 on the first resting platform 5 and be placed on the first platform, and the second end of the pipeline inside column 1 to extend from the mounting hole 7 on the second resting platform 6 and be placed on the second platform, thus facilitating the connection between the pipelines on the first and second platforms.

[0026] In this embodiment, a fireproof and insulating layer 8 is laid on the inner wall of the chamber 1-1 of the column 1. This gives the column 1 good fireproof and insulating properties.

[0027] In this embodiment, the fireproof insulation layer 8 adopts a layered composite structure, having a substrate layer and an outer film layer. The substrate layer is made of ceramicized silicone rubber sheet, and the film is made of mica tape impregnated with epoxy resin.

The column 1 and steps 2, the column 1 and the rest platform, and the steps 2 and support columns 4 are all connected by welding. This facilitates the fixed connection of the column 1, steps 2, support columns 4, and rest platform, and provides good structural strength.

[0029] In this embodiment, the rest platform and step 2 are made of Q235B carbon structural steel and the surface is treated with anti-slip material.

[0030] In this embodiment, a first reinforcing plate is provided between the bottom of step 2 and column 1, and a second reinforcing plate is provided between the bottom of rest platform and column 1. The first reinforcing plate is welded to both step 2 and column 1, and the second reinforcing plate is welded to both rest platform and column 1. This achieves a fixed connection between the first and second reinforcing plates and provides better structural stability for step 2 and rest platform.

[0032] Column 1 is arranged between the first platform and the second platform. The first platform is located above the second platform. Column 1 is hollow and has a chamber 1-1 in the middle that allows pipelines to pass through.

[0033] Step 2 is spirally installed on column 1, and support column 4 is fixedly connected to the end of two adjacent steps 2 away from column 1.

[0034] Guardrail 3 is installed on the end of step 2 away from post 1.

[0035] At least two rest platforms are provided on the column 1 along the length of the column 1. The two ends of the rest platforms are connected to the two steps 2 in front and behind them. The distance between two adjacent rest platforms is 6m.

[0036] The resting platform on column 1 that is close to the first platform is called the first resting platform 5, and the resting platform on column 1 that is close to the second platform is called the second resting platform 6. Mounting holes 7 are made on the side wall of column 1 at positions corresponding to the first resting platform 5 and the second resting platform 6, so that the first end of the pipeline inside column 1 can extend out of the mounting hole 7 at the first resting platform 5 and be arranged on the first platform, and the second end of the pipeline inside column 1 can extend out of the mounting hole 7 at the second resting platform 6 and be arranged on the second platform.

[0037] The column 1, step 2, support column 4, and rest platform are all made of steel. The column 1 and step 2, the column 1 and rest platform, and the step 2 and support column 4 are all connected by welding.

[0038] A first reinforcing plate is provided between the bottom of the step 2 and the column 1, and a second reinforcing plate is provided between the bottom of the rest platform and the column 1.
