Abstract
Description
Technical Field
[0001] This utility model relates to the field of staircase technology, specifically a combined stacked staircase. Background Technology
[0002] With the rise of minimalist luxury interior design, stacked staircases are becoming increasingly popular in home renovations. Stacked staircases, belonging to the Spaca style, feature layered structures and clean lines, making them a favorite among consumers. However, existing stacked staircases present several drawbacks and safety hazards.
[0003] Traditional stacked staircases involve multiple trades, including steelworkers, electricians, carpenters, glazing workers, and tile grout installers. The process is lengthy and involves a wide range of tasks, from installing the steel structure foundation, baseboard foundation, panel installation, lighting installation, glass installation, and tile grout installation. It also requires on-site welding, which is quite inconvenient. Furthermore, due to the extensive use of steel structure materials and panel materials, the overall structure is complex to manufacture and install, resulting in a very high overall cost for traditional stacked staircases. This high cost makes them difficult for consumers to accept. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a combined stacked staircase.
[0005] To solve the above problems, the technical solution of this utility model is: a combined stacked staircase, comprising multiple step units stacked sequentially, with two steel plate beams connected to both ends of the multiple step units.
[0006] The step unit includes a steel support frame and a fixed frame. The support frame is a rectangular frame structure, and the fixed frame is an L-shaped structure located below the support frame. A steel foot pedal is bolted to the top of the support frame. A main base plate is screwed to the outside of the support frame and the fixed frame. A main decorative panel is glued to the outside of the main base plate.
[0007] At least one end of the step unit is fitted with a high-strength aluminum plate on the outside of the steel plate beam. A side base plate is fitted to the side of the high-strength aluminum plate by screws. A side decorative panel is bonded to the outside of the side base plate.
[0008] Furthermore, an L-shaped support bar is fixed to the inner side of the steel plate beam, and the support frame is installed on the support bar by bolts.
[0009] Furthermore, multiple L-shaped corner brackets are fixed to both ends of the fixed frame, and the corner brackets are installed on the steel plate beam by bolts.
[0010] Furthermore, at least one of the steel plate beams is fitted with a glass railing support on its outer side, and a glass railing is fitted on top of the glass railing support.
[0011] Furthermore, the glass railing support is located between the steel plate beam and the high-strength aluminum plate.
[0012] The advantages of this utility model compared with the existing technology are as follows: all materials of the entire staircase are produced in the factory according to the design drawings in one go. On-site installation does not require welding, cutting or secondary processing, saving on-site construction time. All processes can be completed at one time, reducing safety hazards during on-site construction. The overall structure of the staircase is simple, easy to install and low in cost.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0019] like Figures 1 to 4 As shown, a modular stacked staircase includes multiple tread units stacked sequentially, with both ends of the multiple tread units connected to two steel plate beams 1.
[0020] The step unit includes a steel support frame 2 and a fixed frame 3. The support frame 2 is a rectangular frame structure, and the fixed frame 3 is an L-shaped structure located below the support frame 2. A steel foot pedal 4 is bolted to the top of the support frame 2. A main base plate 5 is screwed to the outside of the support frame 2 and the fixed frame 3. A main decorative panel 6 is glued to the outside of the main base plate 5.
[0021] The inner side of the steel plate beam 1 is fixed with an L-shaped support bar 10, and the support frame 2 is installed on the support bar 10 by bolts. Multiple L-shaped corner brackets 11 are fixed at both ends of the fixed frame 3, and the corner brackets are installed on the steel plate beam 1 by bolts.
[0022] At least one end of the step unit is fitted with a high-strength aluminum plate 7 on the outside of the steel plate beam 1. A side base plate 8 is fitted to the side of the high-strength aluminum plate 7 by screws. A side decorative panel 9 is bonded to the outside of the side base plate 8. A glass railing support 12 is fitted to the outside of at least one steel plate beam 1. A glass railing 13 is fitted to the top of the glass railing support 12. The glass railing support 12 is located between the steel plate beam 1 and the high-strength aluminum plate 7.
[0023] In practical use, the entire staircase is disassembled into steel plate beams 1, support frame 2, fixed frame 3, steel treads 4, base plate, decorative panel, high-strength aluminum plate 7, stair railing, etc., and is manufactured as finished products in the factory. All materials of the entire staircase are produced in the factory according to the design drawings in one go. On-site installation does not require welding, cutting, or secondary processing, saving on-site construction time. All processes can be completed at one time, reducing safety hazards during on-site construction.
[0024] The staircase uses a double steel plate beam 1 structure for load bearing. During installation, the step units can be fixed to the supporting materials on the steel plate beam 1 simply by using bolts, screws, etc.
[0025] High-strength aluminum plate 7, used as a decorative beam, not only serves to fix glass railings but also plays a significant decorative role, and is used as the decorative panel below the partition.
