[0002] To improve living conditions in older residential communities, installing elevators in existing buildings is an important measure. During the elevator installation process, in cases where the building structure is not suitable for direct installation, a corridor needs to be built between the elevator and the existing building for connection.

[0003] Currently, the corridors between elevators and existing buildings are mostly assembled on-site using traditional welding methods. However, welding between steel components is time-consuming, resulting in low construction efficiency. Utility Model Content

[0004] To help save construction time and improve construction efficiency to some extent, this application provides a prefabricated modular corridor.

[0005] The prefabricated modular corridor provided in this application adopts the following technical solution: A prefabricated modular corridor includes: The bottom beams are arranged at intervals along the horizontal direction, and the arrangement direction of the bottom beams is perpendicular to the arrangement direction of the elevator and the existing building. One end of the bottom beam is used to connect to the elevator, and the other end is used to connect to the wall of the existing building. A connecting beam assembly, which is detachably disposed between adjacent bottom beams, is used to connect adjacent bottom beams; A floor slab component, which is detachably mounted on an adjacent bottom beam, is used to allow pedestrians to pass through.

[0006] Preferably, each of the bottom beams includes a support beam, an edge beam, and stiffening slabs. One end of the support beam is used to connect to the elevator, and the other end is used to connect to the existing building wall. The connecting beam assembly is disposed between the support beams of adjacent bottom beams. The floor slab component is detachably installed between the support beams of adjacent bottom beams. The edge beam is detachably sleeved on the outside of the support beam and is used to support the connecting beam assembly. The stiffening slabs are disposed inside the support beams, and multiple stiffening slabs are spaced apart along the length of the support beam.

[0007] Preferably, the connecting beam assembly includes a crossbeam and a base frame vertical beam. The crossbeam is detachably disposed between the support beams of adjacent base beams. Multiple crossbeams are spaced apart along the length direction of the support beams. The base frame vertical beam is detachably connected above the multiple crossbeams. Multiple base frame vertical beams are spaced apart along the length direction of the crossbeams. The length direction of the base frame vertical beam is perpendicular to the length direction of the crossbeams. The base frame vertical beam is used to support the floor slab components.

[0008] Preferably, the floor slab component includes multiple floor slabs, which are arranged sequentially along the direction of the elevator and the existing building. Each floor slab is detachably installed between two supporting beams of an adjacent bottom beam. The vertical beam of the base frame abuts against the bottom wall of the floor slab. Each floor slab has a first bent edge on one side and a second bent edge on the other side. The first bent edge is used to engage with the second bent edge of the adjacent floor slab.

[0009] Preferably, the support beam includes multiple beam bodies, which are sequentially spliced ​​together by connectors, and the edge-sealing beam includes multiple edge-sealing plates, which are detachably sleeved on the outside of the beam body.

[0014] Preferably, a ceiling panel is detachably connected between adjacent bottom beams, and multiple ceiling panels are arranged sequentially along the direction of the elevator and the existing building, with the ceiling panels located below the connecting beam assembly.

[0015] In summary, this application includes the following beneficial technical effects: During construction, the connecting beam components are first assembled between adjacent bottom beams on the construction site, and then the floor slab components are assembled on the adjacent bottom beams. Next, the assembled combined corridor is hoisted to the required position of the elevator and the existing building wall using hoisting equipment. The two ends of the bottom beam are then fixed to the elevator and the existing building wall respectively, thus completing the corridor assembly construction. Since there is no need to assemble the corridor by welding on the construction site, it helps to save construction time and improves construction efficiency to a certain extent.

[0025] The following combination Figures 1-8 This application will be described in further detail.

[0026] This application discloses a prefabricated modular corridor. (Refer to...) Figure 1 and Figure 2 The prefabricated modular corridor includes a bottom beam 1, a connecting beam assembly 2, and a floor slab assembly 3. Multiple bottom beams 1 are arranged at intervals along the horizontal direction, with the arrangement direction of the multiple bottom beams 1 perpendicular to the arrangement direction of the elevator and the existing building, and the length direction of the bottom beams 1 parallel to the arrangement direction of the elevator and the existing building. One end of each bottom beam 1 is used to connect to the elevator, and the other end is used to connect to the wall of the existing building. In this embodiment, two bottom beams 1 are provided. In other embodiments, the number of bottom beams 1 can be set according to the preset width of the corridor.

[0027] Reference Figure 1 and Figure 2The connecting beam assembly 2 is detachably disposed between adjacent bottom beams 1. The connecting beam assembly 2 is used to connect adjacent bottom beams 1. In this embodiment, the connecting beam assembly 2 is detachably disposed between two bottom beams 1 to fix the two bottom beams 1 relatively, which helps to form the skeleton of the corridor. The floor slab component 3 is detachably disposed on adjacent bottom beams 1. The floor slab component 3 is used for pedestrian passage.

[0028] During construction, the connecting beam assembly 2 is first assembled between the adjacent bottom beams 1 at the construction site. Then, the floor slab assembly 3 is assembled on the adjacent bottom beams 1. Next, the assembled combined corridor is hoisted to the required position between the elevator and the existing building wall using hoisting equipment. The two ends of the bottom beam 1 are fixed to the elevator and the existing building wall respectively, thus completing the corridor assembly construction. Since there is no need to assemble the corridor by welding on the construction site, it helps to save construction time and improve construction efficiency to a certain extent.

[0029] Reference Figure 2 and Figure 3 Specifically, each bottom beam 1 includes a support beam 12, an edge beam 11, and stiffening slabs 13. One end of the support beam 12 is used to connect to the elevator, and the other end is used to connect to the existing building wall. The connecting beam assembly 2 is detachably installed between the support beams 12 of adjacent bottom beams 1. The floor slab assembly 3 is detachably installed between the support beams 12 of adjacent bottom beams 1. The edge beam 11 is detachably sleeved on the outside of the support beam 12 and is used to support the connecting beam assembly 2. The stiffening slabs 13 are fixedly installed inside the support beam 12, and multiple stiffening slabs 13 are spaced apart along the length of the support beam 12, which helps to strengthen the structural strength of the support beam 12. Furthermore, the stiffening slabs 13 can be snapped into the support beam 12 during its formation.

[0030] Designing the bottom beam 1 as a combination structure of support beam 12, edge beam 11, and stiffening plate 13 not only facilitates the assembly of connecting beam assembly 2 and floor slab component 3, but also provides support for them, thereby improving the overall structural stability of the corridor. In other embodiments, the bottom beam 1 can be designed as a one-piece steel component.

[0031] Reference Figure 3 and Figure 4 Furthermore, the support beam 12 includes multiple beam bodies 121, which are sequentially spliced ​​together by connectors 17. The connectors 17 can be one of the following: connecting plate, angle steel, or connecting frame. No limitation is made here. The two ends of the connectors 17 are located in adjacent beam bodies 121 and are fixed to the two adjacent beam bodies 121 by bolts, screws, or rivets, thereby forming the support beam 12 by splicing multiple beam bodies 121.

[0032] Reference Figure 3 and Figure 4The edge-sealing beam 11 includes multiple edge-sealing plates 111. The edge-sealing plates 111 are detachably fitted onto the outside of the beam body 121 using screws, bolts, or rivets. The edge-sealing plates 111 can correspond one-to-one with the beam body 121, or two edge-sealing plates 111 can correspond to one beam body 121; the specific correspondence method can be set according to needs. Both the support beam 12 and the edge-sealing beam 11 are assembled, facilitating the transportation of steel components, especially for long corridors.

[0033] Reference Figure 4 and Figure 5 To facilitate the connection of adjacent bottom beams 1, the connecting beam assembly 2 includes a horizontal beam 21 and a base frame vertical beam 22. The horizontal beam 21 is detachably installed between the side walls of the support beam 12 of adjacent bottom beams 1 by rivets, screws or bolts. The length direction of the horizontal beam 21 is parallel to the arrangement direction of the multiple bottom beams 1, and multiple horizontal beams 21 are distributed at intervals along the length direction of the support beam 12. The base frame vertical beam 22 is detachably connected above the multiple horizontal beams 21 by rivets, screws or bolts. Multiple base frame vertical beams 22 are distributed at intervals along the length direction of the horizontal beams 21, and the length direction of the base frame vertical beam 22 is perpendicular to the length direction of the horizontal beams 21. The base frame vertical beam 22 is used to support the floor slab component 3.

[0034] Multiple horizontal beams 21 and multiple vertical beams 22 of the base frame form a connecting frame, which fixes the support beams 12 of adjacent base beams 1, thereby improving the overall stability of the corridor.

[0035] Reference Figure 5 To facilitate pedestrian passage, the floor slab component 3 includes multiple floor slab bodies 31, which are distributed sequentially along the arrangement direction of the elevator and the existing building. The floor slab bodies 31 are detachably installed between two supporting beams 12 of adjacent bottom beams 1 by bolts, screws or rivets.

[0036] Reference Figure 5 and Figure 7 Each floor slab 31 has a first bent edge 4 integrally formed on one side and a second bent edge 5 integrally formed on the other side. The first bent edge 4 and the second bent edge 5 are bent in the same direction as the corresponding floor slab 31. The first bent edge 4 is used to engage with the second bent edge 5 of the adjacent floor slab 31. Multiple floor slabs are assembled sequentially to form a passageway for pedestrians. The interlocking of adjacent floor slabs 31 through the first bent edge 4 and the second bent edge 5 can improve the connection stability to a certain extent and enhance the rainwater seepage prevention effect.

[0037] Reference Figure 5 and Figure 6To further enhance the overall strength of the corridor, beam 121 has a first flange 6 at one end and a second flange 7 at the other end. The second flange 7 is inverted L-shaped, and the upper surface of the first flange 6 is lower than the upper surface of the second flange 7. The first flange 6 supports the floor slab 31, and the second flange 7 abuts against the end of the floor slab 31. The two ends of the floor slab 31 are limited by the second flange 7 on the adjacent bottom beam 1 and supported and connected by the first flange 6 of the adjacent bottom beam 1, thereby enabling good load transfer and ensuring the stability of the corridor.

[0038] Reference Figure 5 and Figure 6 The edging plate 111 has a protrusion 8 and an edging portion 9. The protrusion 8 supports the crossbeam 21, and the edging portion 9 covers the upper surface of the second folded edge 7 of the beam 121. The design of the protrusion 8 enables support for multiple crossbeams 21, facilitating the detachable connection between the crossbeam 21 and the side wall of the supporting beam 12. The upper surface of the edging portion 9 is flush with the upper surface of the floor slab 31, thereby helping to ensure the flatness of the corridor surface and improving pedestrian safety.

[0039] Reference Figure 3 and Figure 4 Multiple pre-installed components 18 for connection with the corridor railing are fixedly installed on the second folded edge 7. Adjacent edge plates 111 form a notch on one side (not shown in the figure). The pre-installed components 18 correspond one-to-one with the notch and are located within the corresponding notch. The pre-installed components 18 can be one of the following: pre-installed columns, pre-installed angle steel, or pre-installed protrusions. No limitation is made here. To improve the safety of the corridor, railings or fully enclosed protective covers can be installed on both sides of the corridor using the pre-installed components 18, thereby preventing pedestrians from falling.

[0040] Reference Figure 2 Furthermore, the pre-installed component 18 abuts against the upper surface of the floor slab 31 at the corresponding position, thereby limiting the position of the floor slab 31.

[0041] Reference Figure 5 and Figure 6 A ceiling panel 10 is detachably connected between two edge beams 11 of adjacent bottom beams 1 by screws or rivets. Multiple ceiling panels 10 are arranged sequentially along the direction of the elevator and the existing building. The ceiling panels 10 are located below the cross beam 21, and the ends of the ceiling panels 10 abut against the side wall of the protrusion 8. The edge plates 111 can support multiple ceiling panels 10. Specifically, the ceiling panels 10 have the same specific structure as the floor slab 31. The installation of ceiling panels 10 facilitates the installation of lighting fixtures to provide illumination for the corridor on the next floor.

[0042] Reference Figure 1 and Figure 8To facilitate the connection of the support beam 12 between the elevator and the existing building wall, the two ends of the support beam 12 extend outwards from the edge beam 11. The two ends of the support beam 12 are detachably connected to connecting plates 14 via bolts, screws, or rivets. Connecting plates 15 are detachably mounted on the connecting plates 14 via bolts, screws, or rivets, and the connecting plates 15 are used to connect to the elevator or the existing building wall. Furthermore, drain pipe clamps 16 are bolted to the connecting plates 14, thereby facilitating the installation of drain pipes.

[0043] The implementation principle of this application embodiment is as follows: During construction, multiple beams 121 with stiffening plates 13 are first spliced ​​into support beams 12 at the construction site using connectors 17 and screws, rivets or bolts. Then, the support beams 12 and the edge beams 11 are assembled into beams 121 using screws, rivets or bolts. Next, multiple spliced ​​ceiling panels 10 are installed between two bottom beams 1 using screws, rivets or bolts. Then, multiple horizontal beams 21 are spaced between two bottom beams 1 using screws, rivets or bolts. Next, multiple base frame vertical beams 22 are assembled onto the horizontal beams 21 using screws, rivets or bolts. Then, multiple spliced ​​floor slabs 31 are assembled onto adjacent bottom beams 1 using screws, rivets or bolts. Finally, connecting plates 14 are assembled at the ends of the support beams 12, and joint plates 15 are installed on the connecting plates 14.

[0044] Then, the assembled combined corridor is hoisted to the required position of the elevator and the existing building wall using hoisting equipment. The two ends of the bottom beam 1 are fixed to the elevator and the existing building wall respectively through the joint plate 15, thereby completing the corridor assembly construction. Since the corridor of this application is basically assembled on site using fasteners such as bolts, screws or rivets, it is not necessary to assemble the corridor by welding on the construction site, which helps to save construction time and improve construction efficiency to a certain extent.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
