[0002] ‌A staircase guardrail‌ is a commonly used protective railing on multi-story building staircases, and its main function is safety protection. It is usually called a "staircase protective railing". The design of the staircase guardrail aims to protect the safety of pedestrians on the staircase and also play a role in aesthetics.

[0003] Traditional staircase guardrails are mostly fixed by on-site welding or concrete pouring. The installation process is cumbersome, the operation efficiency is low, and once installed, it is difficult to disassemble and maintain later, with poor flexibility and high maintenance costs.

It solves the problems that traditional staircase guardrails are mostly fixed by on-site welding or concrete pouring, with a cumbersome installation process, low operation efficiency, and being difficult to disassemble and maintain later, having poor flexibility and high maintenance costs.

[0005] To achieve the above object, this application provides the following technical solution: An assembled staircase guardrail includes a staircase. There are equally spaced columns arranged above the staircase. The outer circumferential surface of each column is slidably sleeved with a side pile. Two T-shaped grooves are opened inside each side pile. There are equally spaced guardrails arranged above the staircase. T-shaped mounting plates are fixedly connected to both ends of each guardrail. The outer surfaces of the T-shaped mounting plates are slidably connected to the side piles through the T-shaped grooves respectively. An armrest is fixedly connected to the top of each guardrail.

[0006] Through the above solution, since traditional staircase guardrails are mostly fixed by on-site welding or concrete pouring, with a cumbersome installation process, low operation efficiency, and being difficult to disassemble and maintain later, having poor flexibility and high maintenance costs. By setting multiple columns and side piles, and respectively setting T-shaped grooves and T-shaped mounting plates on the side piles and guardrails, the guardrail is disassembled and assembled, facilitating the transportation and handling of the guardrail, simplifying the installation process of the guardrail, improving the installation efficiency, and also facilitating the disassembly and maintenance of the guardrail, improving the flexibility of the guardrail, and reducing the later maintenance costs.

[0007] Furthermore, the bottom surface of each of the guardrails is fixedly connected with equally spaced reinforcing rods, and the upper surface of the staircase is fixedly connected with equally spaced reinforcing seats, and the outer circumferential surface of the reinforcing rods is slidably inserted into the interior of the reinforcing seats.

[0008] Through the above solution, the guardrail is reinforced by the reinforcing rods and the reinforcing seats, improving the anti-rollover and tilting ability of the guardrail, thereby enhancing the bearing capacity and stability of the guardrail and protecting the safety of pedestrians passing by.

[0009] Furthermore, multiple groups of equally spaced first mounting screw rods are fixedly connected to the upper surface of the staircase, the bottom parts of the columns are respectively slidably sleeved on the outer circumferential surfaces of the first mounting screw rods, and the outer circumferential surface of each first mounting screw rod is threadedly connected with a first nut.

[0010] Through the above solution, the columns are fixed by the first mounting screw rods and the first nuts, and the columns are fixedly installed on the staircase, facilitating the installation and disassembly of the columns.

[0011] Furthermore, the bottom parts of the side piles are respectively slidably sleeved on the outer circumferential surfaces of the first mounting screw rods, the bottom surface of the side piles is in contact with the upper surface of the first nuts, and the outer circumferential surface of each first mounting screw rod is threadedly connected with a second nut.

[0012] Through the above solution, the side piles are fixed by the first mounting screw rods and the second nuts, facilitating the installation and disassembly of the side piles.

[0013] Furthermore, four second mounting screw rods are fixedly connected to the upper surface of each side pile, fixing plates are fixedly connected to both ends of each handrail, the bottom parts of the fixing plates are respectively slidably sleeved on the outer circumferential surfaces of the second mounting screw rods, and the outer circumferential surface of the second mounting screw rods is threadedly connected with a third nut.

[0014] Through the above solution, the handrail is fixed by the second mounting screw rods and the third nuts, the handrail is fixed on two adjacent side piles, thereby fixing the guardrail, improving the stability of the guardrail, and also facilitating the installation and disassembly of the guardrail.

[0015] Furthermore, two limiting plates are fixedly connected to the outer circumferential surface of each column, and the outer surface of the limiting plates is slidably connected with the side pile through an empty groove formed inside the side pile.

[0016] Through the above solution, the side pile is restricted to prevent it from rotating, improving the stability of the side pile, and thus enhancing the overall stability of the guardrail.

[0017] Furthermore, the column is made of a metal material with high hardness, and an anti-rust coating is applied to the outer surface of the column.

[0018] Through the above solution, the column made of a metal material with high hardness has a high bearing capacity, which can improve the overall stability of the guardrail. The anti-rust coating can protect the column, prevent the column from rusting easily, and improve the durability of the column.

[0032] Please refer to Figure 1 、and Figure 2 , multiple groups of first mounting screw rods 9 arranged at equal intervals are fixedly connected to the upper surface of the staircase 1. The bottom parts of the columns 2 are slidably sleeved on the outer circumferential surfaces of the first mounting screw rods 9 respectively. A first nut 10 is threadedly connected to the outer circumferential surface of each first mounting screw rod 9. The column 2 is fixed by the first mounting screw rod 9 and the first nut 10, and the column 2 is fixedly installed on the staircase 1, facilitating the installation and disassembly of the column 2.

[0033] Please refer to Figure 1 、 Figure 2 and Figure 3 , the bottom parts of the side piles 3 are slidably sleeved on the outer circumferential surfaces of the first mounting screw rods 9 respectively. The bottom surface of the side pile 3 is in contact with the upper surface of the first nut 10. A second nut 11 is threadedly connected to the outer circumferential surface of each first mounting screw rod 9. The side pile 3 is fixed by the first mounting screw rod 9 and the second nut 11, facilitating the installation and disassembly of the side pile 3.

[0034] Please refer to Figure 1 、 Figure 3 and Figure 4, on the upper surface of each side pile 3, four second installation screw rods 12 are fixedly connected. At both ends of each handrail 13, fixing plates 14 are fixedly connected. The bottom of the fixing plate 14 is slidably sleeved on the outer circumferential surface of the second installation screw rod 12.

After all the columns 2 and side piles 3 are installed, install the guardrail 5 between adjacent side piles 3 through the T-shaped groove 4 and the T-shaped mounting plate 6. Finally, use the third nut 15 to fix the fixing plate 14 on the side pile 3. The T-shaped groove 4 and the T-shaped mounting plate 6 can restrict the guardrail 5, which not only facilitates the installation of the guardrail 5, simplifies the installation process of the guardrail 5, improves the operation efficiency, but also prevents the guardrail 5 from falling off easily, improves the stability of the guardrail 5, and is also convenient for subsequent disassembly and maintenance.
