DETAILED DESCRIPTION

[0029] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments of the present invention and the features in the embodiments may be combined with each other unless there is a conflict.

[0030] It should be noted that the terms "first", "second", etc. in the specification and claims of the present utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0031] See also Figures 1 to 4 The present invention provides a corridor structure 100 and a retrofittable elevator shaft 1 comprising the same. It should be noted that the retrofittable elevator shaft 1 is a steel structure, with its primary load-bearing structure made of steel. It can preferably be retrofitted to an existing building structure 300 to add an elevator shaft to a building without an elevator.

[0032] The retrofitted elevator shaft 1 also includes a main shaft structure 200, which forms a vertically connected elevator shaft for the elevator to move up and down. The main shaft structure 200 also includes at least two columns 201, which are arranged side by side on the side of the main shaft structure 200 facing the main building structure 300. Each column 201 extends vertically. It is understood that the lower end of each column 201 should be provided with a foundation structure to transfer the load of the main shaft structure 200 to the foundation.

[0033] Furthermore, the corridor structure 100 provided by the present invention is arranged between the elevator main shaft structure 200 and the building main structure 300.

[0034] It should be noted that, in the present utility model, the description of the orientation is defined as follows: the up and down direction refers to the direction roughly perpendicular to gravity, the lateral direction refers to the direction parallel to the facade of the building where the elevator is installed, and the front and back direction is perpendicular to the facade of the building. The front and back direction is perpendicular to the lateral and up and down directions, and the front is the direction of the installed elevator shaft 1 facing the facade of the building, and the rear is the direction of the installed elevator shaft 1 away from the facade of the building.

[0035] Please continue reading Figure 1 and Figure 2In this embodiment, the corridor structure 100 includes a main beam assembly 10 and a diagonal bracing assembly 20. The main beam assembly 10 includes two main beams 11 extending in the front-to-back direction. The two main beams 11 are arranged side by side in the transverse direction and respectively have a first end 111 connected to the elevator main shaft structure 200 and a second end 112 close to the main building structure 300. The elevator main shaft structure 200 includes two columns 201. The first ends 111 of the two main beams 11 are rigidly connected to the two columns 201 in a one-to-one correspondence. The main beam assembly 10 is provided in multiple groups, and the multiple groups of main beam assemblies 10 are arranged in sequence in the up-down direction. In this embodiment, structural plates can be laid on the upper side of the two main beams 11 to form a walkway connecting the interior of the building main body and the elevator shaft.

[0036] There are multiple groups of the diagonal bracing assemblies 20, and the multiple groups of the diagonal bracing assemblies 20 are spaced apart in the up and down directions, and are arranged one-to-one with the multiple groups of the main beam assemblies 10. Each of the diagonal bracing assemblies 20 includes two diagonal bracing rods 21 arranged side by side in the transverse direction, and one end of each diagonal bracing rod 21 is rigidly connected to the corresponding main beam 11, and the other end is rigidly connected to the corresponding column 201. The diagonal bracing rod 21 is arranged to extend upward at an angle from the first end 111 toward the second end 112.

[0037] In this way, the load of the corridor structure 100 can be transferred to the elevator main shaft structure 200 through the diagonal braces 21, and then transmitted downward through the columns 201. This design not only improves the stability of the main beam 11, but also effectively transmits part of the load of the corridor structure 100 to the elevator main shaft structure 200. As a result, the load borne by the second end 112 of the main beam 11 is significantly reduced, thereby reducing the adverse effects of the installed elevator shaft 1 on the main building structure 300 and enhancing the stability and safety of the installed elevator shaft 1 and the overall main building structure.

[0038] For further information, please refer to Figure 1 and Figure 2 A first stiffening plate 12 is welded to the lower middle portion of each main beam 11, and one end of each diagonal brace 21 is bolted to the corresponding first stiffening plate 12. The provision of the first stiffening plate 12 not only enhances the local rigidity and stability of the main beam 11 but also facilitates the installation and removal of the diagonal brace 21, improving construction efficiency and maintenance convenience.

[0039] Preferably, each column 201 is welded with a plurality of second stiffening plates 22 on the side facing the main building structure 300. The plurality of second stiffening plates 22 are spaced apart vertically, and the other end of each diagonal brace 21 is bolted to a corresponding second stiffening plate 22. In this embodiment, the provision of the plurality of second stiffening plates 22 further enhances the local rigidity and stability of the column 201, while facilitating the installation and removal of the diagonal brace 21, thereby improving construction efficiency and maintenance convenience.

[0040] Optionally, the corridor structure 100 further includes a plurality of secondary beams 30, each of which extends transversely and is connected at both ends between two primary beams 11 on the same level. The plurality of secondary beams 30 are arranged side by side in the front-to-back direction. In this embodiment, the connection of the plurality of secondary beams 30 to the coupling beam assembly improves the overall rigidity and stability of the corridor structure 100, and also enhances its load-bearing capacity and seismic resistance.

[0041] Based on the above embodiment, each of the diagonal braces 21 and each of the secondary beams 30 is a channel steel. The cross-sections of the diagonal braces 21 and the secondary beams 30 are both roughly C-shaped. This ensures that the diagonal braces 21 and the secondary beams 30 have high strength and rigidity, effectively carrying the load of the corridor structure 100, and further improving the stability and safety of the corridor structure 100.

[0042] In a preferred embodiment, see Figure 1 , each of the main beams 11 is an H-shaped steel and is screwed to the corresponding column 201 by high-strength bolts. Each main beam 11 has two main boards 131 arranged side by side in the upper and lower directions and a web 132 connecting the two main boards 131. In the two main beams 11 on the same layer, each main beam 11 has a groove 133 facing the other main beam 11. A reinforcing plate 31 is provided in the groove 133. The reinforcing plate 31 is perpendicular to the corresponding main beam 11 and is welded and fixed to the two main boards 131 and the web 132 of the corresponding main beam 11. The two ends of each secondary beam 30 are screwed to the corresponding reinforcing plate 31. In this embodiment, the secondary beam 30 is connected by the reinforcing plate 31 embedded in the groove 133. On the one hand, the overall rigidity and stability of the main beam 11 are improved. On the other hand, it is convenient for the installation and fixation of the secondary beam 30, thereby improving the bearing capacity and seismic performance of the corridor structure 100.

[0043] On the basis of the above embodiments, in the first embodiment provided by the present utility model, as Figure 1As shown, the corridor structure 100 also includes two corridor columns 40 extending in the up-down direction. The two corridor columns 40 are arranged side by side in the transverse direction and rigidly connect the two second ends 112 of each main beam assembly 10 in a one-to-one correspondence. In this embodiment, the corridor columns 40 are arranged outside the original building main structure 300, and a construction joint can be reserved between the building main structures 300. This structure is suitable for situations where the bearing capacity of the building main structure 300 itself is insufficient to add an elevator shaft. It uses the corridor columns 40 to transfer the load to the foundation without the need to rely on the building main structure 300 for bearing. It should be noted that in this embodiment, the diagonal bracing assembly 20 transfers more load to the elevator main shaft structure 200, which can reduce the disturbance to the foundation of the building main structure 300, and also plays a role in reducing the adverse effects on the original building main structure 300 and improving the stability and safety of the added elevator shaft 1 and the overall structure of the building main body.

[0044] In the second optional embodiment, see Figures 2 to 4 In this embodiment, the main building structure 300 bears part of the load of the corridor structure 100, and there is no need to set up additional corridor columns 201. This has the effect of making construction more convenient, reducing labor and materials, and lowering construction costs. Specifically, multiple embedded connectors 301 can be embedded in the main building structure 300, and it is best to embed the embedded connectors 301 in the ring beam of the main building structure 300. Figures 3 and 4 Each embedded connector 301 includes a first connecting plate 311 riveted to the main building structure 300, and a second connecting plate 312 protruding from the outside of the first connecting plate 311 toward the elevator main shaft structure 200. Each second end 112 is hingedly connected to each second connecting plate 312. It is understood that the first connecting plate 311 can be attached to the outside of the ring beam and riveted to the ring beam using multiple bolts.

[0045] In this embodiment, the connection between the embedded connector 301 and the main beam 11 is utilized to transfer part of the load of the corridor to the main building structure 300. It should be noted that in this embodiment, the diagonal bracing assembly 20 transfers more load to the elevator main shaft structure 200, which can reduce the disturbance to the main building structure 300, such as its ring beam, and also play a role in reducing the adverse effects on the original main building structure 300 and improving the stability and safety of the installed elevator shaft 1 and the overall structure of the main building. At the same time, by connecting the corridor structure 100 and the original main building structure 300 in a hinged manner, the disturbance of the corridor structure 100 to the main building structure 300 is minimized, thereby reducing the adverse effects on the original main building structure 300 and improving the stability and safety of the installed elevator shaft 1 and the overall structure of the main building.

[0046] The connection method between the second end 112 of the main beam 11 and the corresponding embedded connector 301 can be selected according to the profile of the main beam 11 itself. Figure 3 Each of the main beams 11 is an H-shaped steel, and each of the second ends 112 is hinged to each of the second connecting plates 312 by bolts. In this way, the main beam 11 and the second connecting plate 312 are reliably hingedly connected by screw connection, which is convenient to construct and reliable.

[0047] In an alternative second embodiment, see Figure 4 Each of the main beams 11 is made of square steel tubes, and each of the second ends 112 is fixed with an end plate 113, and each of the end plates 113 is hingedly connected to each of the second connecting plates 312 by bolts. This hinged connection between the main beam 11 and the second connecting plate 312 by screwing is convenient to construct and reliable.

[0048] Obviously, the embodiments described above are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, those skilled in the art can make other variations or modifications without creative work, which should fall within the scope of protection of the present invention.
