Detailed Implementation

[0035] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0036] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0037] Please see Figures 1 to 5 This utility model provides an external enclosure structure for an elevator shaft. It should be noted that in this utility model, the load-bearing structure of the elevator shaft is a steel structure, which includes multiple steel columns 10. The attached drawings only show an example of setting an external enclosure structure between two columns 10. It can be understood that the external enclosure structure is not limited to being set on one side of the elevator shaft, but can be set on the periphery of the elevator shaft according to actual needs.

[0038] It should be noted that, in this utility model, the description of orientation is limited as follows: The up-down direction refers to the direction approximately perpendicular to gravity; generally, the extension direction of the column 10 is the up-down direction. The inner side refers to the direction in which the outer enclosure structure faces the inside of the elevator shaft, while the outer side is the opposite, facing away from the inside of the elevator shaft. As for the lateral direction, it generally refers to the direction extending between the two columns 10, perpendicular to both the up-down and inward / outward directions.

[0039] Please continue reading. Figures 1 to 5In this utility model, the elevator shaft external enclosure structure includes a keel 20, corner members 30, and a step plate assembly 40. The keel 20 is fixed to the elevator shaft column 10, and is preferably a galvanized square tube to provide better strength and corrosion resistance, thus extending the service life of the external enclosure structure. The keel 20 can be fixed to the column 10 in various ways, such as by screwing or welding. Preferably, three galvanized square tubes are provided, including one first square tube 21 and two second square tubes 22. The two second square tubes 22 are respectively located on both sides of the first square tube 21 in the horizontal direction and are arranged side-by-side with the first square tube 21. The two corner members 30 are fixed to the two second square tubes 22 one-to-one. Thus, through a reasonable configuration of square tubes, not only is the load-bearing capacity of the external enclosure structure improved, but the installation process of the step plate 50 is also optimized, making the entire external enclosure structure more stable.

[0040] At least two external corner members 30 are provided. In this embodiment, two external corner members 30 are provided, which are distributed laterally at intervals and respectively connected and fixed to the keel 20. Each external corner member 30 has a slot 31 extending vertically along its length and has an insertion opening 32 on one side of the slot 31 in the horizontal direction. In this embodiment, the external corner member 30 provides a slot 31 for inserting the step plate 50 from top to bottom. Preferably, each external corner member 30 is fixed to the keel 20 by self-tapping screws. This achieves a stable and reliable connection and fixation between the external corner member 30 and the keel 20.

[0041] The stepped plate assembly 40 includes multiple stepped plates 50, which are connected sequentially from bottom to top. Each stepped plate 50 is inserted into the slots 31 of two external corner members 30 at its two ends in the horizontal direction and fixed to the outside of the keel 20. In this embodiment, the external enclosure structure is constructed in sections. After installing a section of external corner member 30, multiple stepped plates 50 are inserted into the slots 31 sequentially from top to bottom, and the multiple stepped plates 50 are fixed one by one by the interlocking structure between adjacent two stepped plates 50. Each stepped plate 50 is then connected and fixed to the keel 20. This provides a simple and efficient installation method for the external enclosure structure.

[0042] Based on the previous embodiment, please continue to refer to... Figures 6 to 9In the stepped plate assembly 40, the structure of each stepped plate 50 is as follows: Each stepped plate 50 includes an upper plate body 51, a lower plate body 52, and a connecting plate body 53. The upper plate body 51 extends inclinedly from top to bottom and outward. An upper hook portion 511 is provided at the upper end of the upper plate body 51. The upper hook portion 511 has a hook groove 512 with an opening facing downward. The upper hook portion 511 is formed by bending outward and downward from the upper edge of the upper plate body 51. The lower plate body 52 is located below the upper plate body 51. The lower plate body 52 extends inclinedly from top to bottom and outward. A lower hook portion 521 is formed at the lower end of the lower plate body 52. ​​The lower hook portion 521 is formed by bending inward and upward from the lower edge of the lower plate body 52. ​​The lower hook portion 521 includes a hook plate 522 for insertion into the slot of the channel steel 41 or into the hook groove 512 of another stepped plate 50. The connecting plate 53 extends inward and outward and is integrally formed with the upper plate 51 and the lower plate 52. The outer edge of the connecting plate 53 is connected to the lower edge of the upper plate 51, and the inner edge of the connecting plate 53 is connected to the upper edge of the lower plate 52.

[0043] In this embodiment, the upper plate 51 has an upper hook 511 at its upper end, characterized by a hook groove 512 that opens downwards and bends outwards. This allows the step plate 50 to be easily hooked from the inside onto the keel 20 and / or the lower hook 521 of another step plate 50. The lower plate 52 has a lower hook 521 at its lower end, and its upward bending design on the inside allows the step plate 50 to be securely connected to the upper hook 511 or the channel steel 41 below. The connecting plate 53 extends inwards and outwards and is integrally formed with the upper and lower plates 52, ensuring the overall stability and sealing of the structure. This structural design allows the step plate 50 to be easily fixed to the keel 20 from the inside, and the interlocking operation of the upper hook 511 and the lower hook 521 can also be easily performed from the inside of the elevator shaft. This eliminates the need to erect scaffolding on the outside of the elevator shaft, reducing the space occupied on the construction site, lowering safety risks during construction, and improving construction efficiency.

[0044] Preferably, the connecting plate extends downwards at an angle from the inside out. This angled design allows rainwater to flow away more easily from the surface of the plate, reducing the possibility of water retention and further improving the waterproof performance and aesthetics of the external enclosure structure.

[0045] In optional embodiments, please refer to [reference needed]. Figure 6 and Figure 8The stepped plate assembly also includes a channel steel 41 with a U-shaped cross-section and a groove. The channel steel 41 is fixed to the keel 20 with the groove facing downwards. The lower hook 521 of the lowest stepped plate 50 among the plurality of stepped plates 50 hooks into the channel steel 41, and the hook plate 522 is inserted into the groove. In this embodiment, during the installation of the elevator shaft external enclosure structure, the channel steel 41 is first fixed to the keel 20. Then, when installing the lowest stepped plate 50, the stepped plate 50 is inserted from top to bottom into the slot 31 of the external corner member 30. After insertion, the hook plate 522 of the lowest stepped plate 50 is hooked into the U-shaped groove of the channel steel 41 to fix the lower end of the stepped plate 50. Then, the stepped plate 50 can be pulled upwards to fix its upper plate 51. Thus, a simple and reliable structure is provided to achieve the installation and fixation of the lowest stepped plate 50.

[0046] Furthermore, please refer to the following: Figure 6 and Figure 7 The stepped plate assembly 40 also includes a connecting clip 42. The upper end of the connecting clip 42 is provided with a fixing part 421, which is fixed to the first square tube 21. The lower end of the connecting clip 42 is provided with a hook part 422, which hooks into the hook groove 512. In this embodiment, the hook part 422 of the connecting clip 42 is bent inwards. When assembling the stepped plate 50, the lower hook part 521 of its lower plate 52 can first be hooked into the channel steel 41 or the upper hook part 511 of another stepped plate 50 for fixation. Then, its upper hook part 511 is lifted to engage with the hook part 422 of the connecting clip 42, thus achieving the assembly and fixation of the stepped plate 50. The operation is simple, and the structure is stable and reliable.

[0047] In an optional embodiment, please refer to Figures 2 to 5 The elevator shaft external enclosure structure also includes multiple fireproof boards 60, specifically calcium silicate fireproof boards 60. These fireproof boards 60 are installed on the inner side of the keel 20, and crack-resistant mesh is affixed to the interface between adjacent fireproof boards 60. The use of fireproof boards 60 significantly improves the fire resistance of the external enclosure structure, while the application of crack-resistant mesh enhances the connection strength between the fireproof boards 60, improving overall safety. Preferably, a fire-retardant coating is also applied to the outside of the crack-resistant mesh.

[0048] Optionally, please refer to Figures 1 to 5 The elevator shaft external enclosure structure also includes a rock wool insulation layer 70, which is sandwiched between the stepped slab assembly 40 and the multiple fireproof boards 60, and fills the space between the first square tube 21 and the two second square tubes 22. In this embodiment, the addition of the rock wool insulation layer 70 not only improves the thermal insulation performance of the external enclosure structure, but also increases the sound insulation effect of the entire structure, providing a more comfortable operating environment for the elevator shaft.

[0049] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the protection scope of this utility model.
