Description

Technical Field

[0001] This utility model specifically relates to a prefabricated steel structure spiral staircase, belonging to the technical field of spiral staircases. 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 upward form gives a feeling of flow and ascent, increasing the sense of layering and dynamism in the space, making it a highlight in architectural design. Spiral staircases can be customized to 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 eyes 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. However, during the design and construction process, safety and comfort must be fully considered to ensure that they become a highlight of the building rather than a safety hazard.

[0003] The main technical challenge in designing existing spiral staircases is their stability. Due to the spiral design, stability becomes the primary concern, and existing solutions struggle to address this issue.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0006] This utility model achieves the above-mentioned objectives through the following technical solution: a prefabricated steel structure spiral staircase includes a brick wall, a steel frame spiral staircase fixedly installed on one side of the brick wall, steps provided inside the steel frame spiral staircase, each step including an embossed steel plate and a flame-retardant base plate, a galvanized support angle steel plate on one side of the brick wall also fixedly connected to the ground, a galvanized support angle steel plate fixedly installed on one side surface of the brick wall by M12 chemical bolts, a galvanized steel tube fixedly welded to one side surface of the galvanized support angle steel plate, one end of the galvanized steel tube penetrating one side surface of the brick wall, and one end of the galvanized steel tube being fixedly connected to the steel frame spiral staircase.

[0007] Furthermore, in order to determine the number of steps based on the height of the steel frame spiral staircase, the steel frame spiral staircase has 40 steps.

[0008] Furthermore, in order to increase the support stability and firmness of the steel frame spiral staircase by using galvanized square tubing, and to increase the flame-retardant properties of the steel frame spiral staircase by using flame-retardant sidewall panels, a main beam shaped steel plate is provided at the bottom of the cross-section of the steel frame spiral staircase, galvanized square tubing is provided inside the steel frame spiral staircase, flame-retardant sidewall panels are fixedly installed on the sidewalls of the steel frame spiral staircase, and gypsum board is fixedly installed on the outside of the flame-retardant sidewall panels.

[0009] Furthermore, in order to increase the support force of the steps through the embossed steel plate and thus support pedestrians, the flame-retardant tread base plate is fixedly installed on the upper surface of the embossed steel plate.

[0010] Furthermore, to facilitate pedestrian movement, kick lights are evenly distributed on the inner surface of the steel frame spiral staircase.

[0011] Furthermore, to facilitate stable walking for pedestrians, a wooden handrail is provided on the upper inner side of the steel frame spiral staircase along the laying direction of the steel frame spiral staircase.

[0012] The beneficial effects of this utility model are: the connection between the steel frame spiral staircase and the brick wall greatly increases the stability of the steel frame spiral staircase, thereby increasing the service life of the device. At the same time, the flame-retardant plate installed in the device increases the safety of the device, and the installation of kick lights and wooden handrails for pedestrians increases the practical effect of the device.

A steel frame spiral staircase 2 is fixedly installed on one side of the brick wall 1. Steps 3 are provided inside the steel frame spiral staircase 2. Each step 3 includes an embossed steel plate 301 and a flame-retardant base plate 302. A galvanized support angle steel plate 6 is fixedly installed on one side of the brick wall 1 using M12 chemical bolts 5. A galvanized steel tube 7 is fixedly welded to one side of the galvanized support angle steel plate 6. One end of the galvanized steel tube 7 penetrates one side of the brick wall 1, and the other end of the galvanized steel tube 7 is fixedly connected to the steel frame spiral staircase 2. This allows the galvanized support angle steel plate 6 to be fixedly connected to the ground using bolts during construction, thereby achieving... The galvanized support angle steel plate 6 is first stably connected to the ground, and then fixed to the brick wall 1 by M12 chemical bolts 5, thereby increasing the stability between the galvanized support angle steel plate 6 and the brick wall 1. After the galvanized support angle steel plate 6 is installed, the workers then fix and weld the galvanized steel tube 7 to the galvanized support angle steel plate 6, so that the galvanized steel tube 7 penetrates the brick wall 1 and is fixedly connected to the steel frame spiral staircase 2 through the brick wall 1.
