Description

Technical Field

[0001] This utility model relates to the field of elevator shaft technology, specifically to a structure for adding an elevator shaft. Background Technology

[0002] An elevator shaft is a vertical passageway specifically constructed within an existing building for the installation of an elevator. This shaft not only provides operating space for the elevator car and counterweight, but is also a crucial structure ensuring the safe and stable operation of the elevator. Adding an elevator shaft involves constructing an elevator operating shaft next to a building that does not have its own internal shaft space, providing an elevator operating environment for older buildings that require elevators.

[0003] A search revealed a proposed elevator shaft structure with publication number CN210396218U, comprising a shaft base, several shaft frames, and a shaft roof. This structure is intended to overcome the drawbacks of brick-built or reinforced concrete shafts. However, the existing shaft structure is relatively simple, and its stability is limited to cement columns, resulting in poor structural stability, strength, and resistance to impact and tilting. Therefore, we propose a proposed elevator shaft structure. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides an improved elevator shaft structure, please refer to [link / reference]. Figures 1-3The system includes: a corner post 1, with an anchor bolt 2 inserted through the middle of the corner post 1. The corner posts 1 are evenly distributed at equal intervals along the outer wall of the anchor bolt 2. An anchor post 3 is fixed to the bottom end of the anchor bolt 2, and the anchor post 3 forms an expansion connection with the corner post 1 through the anchor bolt 2. The anchor post 3 is used to be buried under the ground at the installation point of the elevator by grouting to support and stabilize the anchor bolt 2. Connection holes 4 are opened on the outer walls of both ends of the corner post 1. The two ends of the corner post 1 are connected to a well frame 5 through the connection holes 4 and bolts. 4 is threadedly connected to the well frame 5, and adjacent well frames 5 are perpendicular to each other. Slots 6 are cut at both ends of the well frame 5, and X-shaped cross posts 7 are welded inside the slots 6. The slots 6 and cross posts 7 are symmetrically arranged about the central axis of the well frame 5. The cross posts 7 welded inside the slots 6 are used to reduce the weight of the well frame 5 while reinforcing its structural strength, ensuring the stability of the well frame 5 after installation. Sound-absorbing cotton 8 is laid on both sides of the slots 6, and the sound-absorbing cotton 8 is about the central axis of the slots 6. The lines are symmetrically positioned, and the sound-absorbing cotton 8 is used to reduce the noise generated by the elevator during operation in the elevator shaft. The outer walls at both ends of the shaft frame 5 are also provided with connection holes 4. The outer surface of the shaft frame 5 is fitted with an outer decorative panel 9 through the connection holes 4 and bolts. The outer decorative panel 9 is threadedly connected to the shaft frame 5 through the corner post 1 and the connection holes 4, and the inner surface of the outer decorative panel 9 is tightly fitted with the outer surface of the shaft frame 5. The outer decorative panel 9 is used to cover and protect the shaft frame 5, preventing direct damage to the shaft frame 5 when subjected to impact or collision, providing additional aesthetic and protective functions. In addition, it works with the anchor post 3 and anchor bolt 2 to fix the corner post 1 and connecting screw 10 to the shaft frame 5, improving the overall stability of the shaft structure and preventing the shaft from tilting. The outer walls at both ends of the shaft frame 5 are provided with connecting screw 10, which is used to connect the upper and lower shaft frames 5 to prevent the shaft frame 5 from shifting. The outer wall of the shaft frame 5 away from the corner post 1 is fitted with a door frame 11 through bolts. The door frame 11 is used to provide a window for opening and closing the elevator door.

[0021] Please see Figure 1 and Figure 4 An elevator shaft structure includes: a building connection plate 12 fixed on the lower surface of a door frame 11 away from the shaft frame 5, the building connection plate 12 being perpendicular to the door frame 11, and a reinforcing plate 13 welded to the lower outer wall of the building connection plate 12, the reinforcing plate 13 being parallel to the building connection plate 12. The building connection plate 12 and the reinforcing plate 13 welded to the lower end facilitate the connection between the elevator shaft and the building, providing a passage for elevator access and strengthening the structural strength of the elevator shaft by connecting to the building facade.

[0022] Working principle: For this type of elevator shaft structure, workers first embed anchor columns 3 and some bottom anchor bolts 2 in the predetermined positions of the elevator shaft through excavated foundation and concrete grouting. Then, according to the height of the elevator shaft, a suitable number of corner columns 1 are selected and fitted onto the anchor bolts 2 to initially fix the corner columns 1. Subsequently, workers use fasteners to connect the outer shaft frame 5, outer decorative panel 9, and corner columns 1 through the connecting holes 4. The upper and lower shaft frames 5 are connected and stabilized by connecting bolts 10 to prevent misalignment or movement between the upper and lower shaft frames 5. The shaft frames 5 are further secured by cross-welded joints within the slots 6. Column 7 is structurally reinforced, and sound-absorbing cotton 8 and exterior panels 9 provide sound insulation and impact protection. Combined with the anchor column 3 and anchor bolt 2 for the diagonal column 1, the elevator shaft structure has good stability and impact resistance. Finally, a door frame 11 for opening and closing the elevator door is installed on one side of the shaft frame 5 with fasteners. The door frame 11 is used for residents to enter and exit the elevator, and the door frame 11 is connected to the building where it is installed by a building connection plate 12. The building connection plate 12 is structurally reinforced by a reinforcing plate 13 welded to the lower end. While safely supporting the passage of residents, it can also stabilize the shaft structure through the exterior facade of the connected building.
