[0028] Please refer to Figure 1 and Figure 4 , the present application provides an elevator shaft 100, the elevator shaft 100 includes a frame structure 101 and a plurality of first support plates 20. Wherein, the frame structure 101 includes a plurality of support columns 10, wherein two support columns 10 form the open door surface of the frame structure 101. The open door surface of the frame structure is formed with a plurality of door hole structures 30 arranged along the height direction z of the elevator shaft 100. Each layer of door hole structure 30 includes a threshold beam 311, an upper door beam 312 and two door columns 32, the upper door beam 312 is arranged above the threshold beam 311 along the height direction of the elevator shaft 100, the two ends of the threshold beam 311 and the upper door beam 312 respectively extend to the two support columns 10 of the frame structure 101, and the two ends of each door column 32 are respectively connected to the upper door beam 312 and the threshold beam 311. And, in the adjacent two layers of door hole structure 30, the threshold beam 311 of one layer is connected with the upper door beam 312 of the other layer through the first support plate 20.

[0029] It can be understood that by arranging the first support plate 20 between the adjacent two layers of door hole structure 30, the plurality of first support plates 20 can be connected to form a whole between the plurality of door hole structures 30, thereby facilitating to improve the structural strength and carrying capacity of the elevator shaft 100. Moreover, the load at the connection position of the adjacent two layers of door hole structure 30 can be more evenly distributed along the first support plate 20, thereby avoiding the stress concentration phenomenon, and facilitating to improve the durability of the elevator shaft 100.

[0030] Optionally, in an embodiment, the two ends of the first support plate 20 are respectively attached to the surfaces of the corresponding upper door beam 312 and sill beam 311 and connected with the corresponding upper door beam 312 and sill beam 311 along the height direction z of the elevator shaft 100.

[0031] Specifically, the two ends of the first support plate 20 are connected with the upper door beam 312 and sill beam 311 by bolts or welding. When the first support plate 20 is connected with the upper door beam 312 and sill beam 311 by bolts, the number of bolts is multiple, and the multiple bolts are uniformly arranged along the width direction x of the elevator shaft 100.

[0032] In an embodiment, the first support plate 20 is arranged near the middle part of the upper door beam 312 and sill beam 311 along the width direction x of the elevator shaft 100. It can be understood that, since the two ends of each upper door beam 312 and sill beam 311 are connected with two support columns 10 respectively, the middle part of the upper door beam 312 and sill beam 311 is the weak point of the upper door beam 312 and sill beam 311. By arranging the first support plate 20 near the middle part of the upper door beam 312 and sill beam 311, the first support plate 20 can support the upper door beam 312 and sill beam 311 near the middle part of the upper door beam 312 and sill beam 311, thereby facilitating to improve the load bearing capacity of the upper door beam 312 and sill beam 311.

[0033] Further, the first support plate 20 is located between the two door stanchions 32 along the width direction x of the elevator shaft 100. In each door opening structure 30, each door stanchion 32 forms a support between the upper door beam 312 and sill beam 311, and thus the position between the two door stanchions 32 is the structural weak point of the upper door beam 312 and sill beam 311. By arranging the first support plate 20 between the two door stanchions 32, it is beneficial to make the load on the upper door beam 312 and sill beam 311 more evenly distributed.

[0034] Optionally, in an embodiment, the length of the first support plate 20 is equal to the distance between the two door stanchions 32 along the width direction x of the elevator shaft 100. In this way, the strength of the door opening structure 30 is improved, and at the same time, the size of the first support plate 20 is prevented from being too large, thereby avoiding material waste and cost increase.

[0035] The elevator shaft 100 further comprises a plurality of second support plates 40, in each door opening structure 30, each door stanchion 32 is connected with the support column 10 adjacent thereto by the second support plate 40 along the width direction x of the elevator shaft 100. The second support plate 40 forms a support between the door stanchion 32 and the support column 10, thereby facilitating to improve the load bearing capacity of the door opening structure 30. Moreover, the load at the connection position of the door stanchion 32 and the support column 10 can be more evenly distributed along the second support plate 40, thereby avoiding stress concentration phenomenon, and facilitating to improve the durability of the elevator shaft 100 in use.

[0036] Optionally, in an embodiment, the two ends of the second support plate 40 are respectively attached to and connected with the corresponding door stanchion 32 and the corresponding support column 10 along the width direction x of the elevator shaft 100.

[0037] Specifically, the two ends of the second support plate 40 are respectively connected with the door stanchion 32 and the support column 10 by fasteners along the width direction x of the elevator shaft 100, wherein the fasteners can be configured as bolts; or the two ends of the second support plate 40 are respectively welded with the door stanchion 32 and the support column 10.

[0038] Optionally, in an embodiment, the second support plate 40 is connected with the middle part of the door stanchion 32 along the height direction z of the elevator shaft 100. It can be understood that since the two ends of each door stanchion 32 are respectively connected with the upper door beam 312 and the threshold beam 311, the position close to the middle part of the door stanchion 32 is the weak point of the door stanchion 32, and connecting the second support plate 40 with the middle part of the door stanchion 32 facilitates to improve the load bearing capacity of the door stanchion 32. The size of the second support plate 40 along the height direction z of the elevator shaft 100 can be freely set according to requirements.

[0041] Further, the circumferential edge of each corridor plate 220 is provided with a fence 240, and along the height direction z of the elevator shaft 100, the top end of the fence 240 is spaced apart from the corridor plate 220 located above it, and forms an open space 250 that communicates with the corridor space 230. In this way, the side of the elevator shaft 100 forms an open corridor structure, reducing the wind area of the elevator, so as to avoid deformation or tilting of the elevator under the action of wind load. That is, the lateral force resistance performance of the elevator is improved, which is beneficial to ensure the safe and stable operation of the elevator.

It can be understood that the triangular support structure has strong stability, so as to make the corridor structure 200 not easy to deform.
