[0002] Steel structure corridors, with their light weight, high strength and fast construction, have been widely used in commercial buildings, industrial plants and civil buildings. Especially in super high-rise buildings and large industrial parks, it is not only an elegant transition between indoor and outdoor spaces, but also plays a key connection and support function. For the installation of large-span steel corridors, the conventional practice is to complete the assembly on the ground first, and then use the hydraulic lifting device and cable system to lift it to the preset position for assembly and docking.

[0041] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0042] Embodiment 1

[0043] like Figure 1-2 As shown, an embodiment of the present invention provides a multi-story steel structure large-span corridor lifting device, including a steel corridor body 10, and docking parts 11 are provided at both ends of the steel corridor body 10. A corresponding number of steel corridor bodies 10 are assembled based on corridors at the same vertical position on the construction drawings, and lifting components 30 are assembled at both ends of each steel corridor body 10. At the same time, track components 20 are vertically erected at the embedded connectors 50 on both sides of the wall. Through the gear transmission mechanism between the lifting component 30 and the two track components 20, the steel corridor body 10 is smoothly lifted. When the steel corridor body 10 is lifted to the predetermined position, the relevant sensor will immediately detect and stop moving to ensure accurate positioning. Subsequently, the steel corridor body 10 is fixed to the connector 50 on the wall. It should be noted that when lifting and fixing the multi-story steel structure corridor, the top-down order should be followed to ensure construction safety and efficiency.

[0044] like Figure 3-4 As shown, there are two lifting assemblies 30, which are arranged at both ends of the steel corridor body 10. The lifting assemblies 30 include a lifting frame 31, a driving motor 33 and a corridor clamp 34. A main fixing plate 3101 is arranged in the middle of one side of the lifting frame 31, and a motor fixing plate 3102 is arranged on the other side near the top. Sliders 32 are arranged at the four corners of the lifting frame 31 on this side. The driving motor 33 is fixed to the motor fixing plate 3102 from the direction of the main fixing plate 3101, and its output shaft passes through the motor fixing plate 3102. There are two corridor clamps 34, which are respectively arranged on both sides of the middle part of the lifting frame 31. The corridor clamps 34 are used to clamp and fix the steel corridor body 10.

[0045] Among them, the corridor clamp 34 includes a connecting plate 3401 arranged on the main fixing plate 3101, and an embedded plate 3402 is arranged on the connecting plate 3401. A clamping screw 3403 is threadedly connected to one side of the embedded plate 3402. The cross-section of the embedded plate 3402 is L-shaped. The embedded plate 3402 of this shape can quickly hang the steel corridor body 10 on two sets of corridor clamps 34. After the calibration module 43 calibrates the unknown steel corridor body 10, the clamping screw 3403 can be tightened to fix the steel corridor body 10 on the embedded plate 3402.

[0046] like Figure 5As shown, the track assembly 20 includes a fixed frame 21 and a rack 23. The fixed frame 21 is fixed to the floor walls on both sides by tension screws. A rack 23 is provided on one side of the fixed frame 21 near the middle in the vertical direction. The lifting assembly 30 is slidably set on the fixed frame 21, and a transmission gear 3301 is provided at the output end of the driving motor 33. The transmission gear 3301 passes through the lifting frame 31 and meshes with the rack 23. The calibration assembly includes a control module 40. The control module 40 is used to control the operation of the lifting assembly 30 and control the posture of the steel corridor body 10 during the lifting process.

[0047] Furthermore, the fixed frame 21 includes two first vertical channel steels 2101 and two horizontal channel steels 2103, a guide rail 22 is arranged on one side of the first vertical channel steel 2101, a second vertical channel steel 2102 is arranged between the two horizontal channel steels 2103, a tension screw is arranged between the second vertical channel steel 2102 and the floor wall, and the rack 23 is fixedly arranged on one side of the second vertical channel steel 2102. Since the second vertical channel steel 2102 is the main force-bearing part of the rack 23, its stability is ensured by the tension screw to avoid loosening during the gear transmission process to cause a safety accident.

[0048] like Figure 6 As shown, the slider 32 on the lifting assembly 30 is slidably set on the guide rail 22, and the two cooperate to ensure the sliding stability of the lifting assembly 30 on the track assembly 20, and the transmission gear 3301 on the output end of the driving motor 33 is engaged with the rack 23.

[0049] like Figure 7 As shown, the control module 40 includes a base lifting control module 42, a calibration module 43, an angle adjustment module 44 and a control console 41, wherein:

[0050] The basic lifting control module 42 is used to control the operation of the lifting component 30 on the track component 20, including two pressure sensors 4201 and a plurality of displacement sensors 4202. Two right-angle steel plates are respectively arranged at both ends of one side of the second vertical channel steel 2102 close to the rack 23. The pressure sensors 4201 are respectively arranged on the opposite sides of the two right-angle steel plates. The function of the pressure sensor 4201 is mainly to transmit an emergency stop signal when the lifting component 30 is at the upper and lower critical values ​​on the track to avoid the driving motor 33 from continuing to run after being at the extreme value, thereby causing a construction accident. Specifically, when the lifting component 30 is at the upper and lower critical values ​​on the track, the driving motor 33 is prevented from continuing to run after being at the extreme value, thereby causing a construction accident. When the component 30 moves to any end point of the track component 20, the lifting frame 31 contacts the pressure sensor 4201, and a signal is generated to the control console 41, thereby controlling the drive motor 33 to stop. The displacement sensor 4202 is set on one side of the first vertical channel steel 2101. The number of displacement sensors 4202 is the same as the number of the steel corridor body 10. Each displacement sensor 4202 is respectively set at the connecting member 50 on each floor. It is used to transmit a signal to the control console 41 when it is checked that the lifting component 30 rises to the preset position (that is, the docking point of the connecting member 50), thereby controlling the drive motor 33 to stop.

[0051] The calibration module 43 is used to calibrate any docking part 11 on the steel corridor body 10 to be in the same vertical position relationship with the pre-buried connecting parts 50 on the floor in the vertical direction. It includes two infrared sensors 4301. The infrared sensors 4301 are arranged on both sides of the lifting frame 31 and are located above the corridor clamp 34. When the steel corridor body 10 is placed on the embedded plate 3402, the edge contours of the docking parts 11 at both ends are at the same distance from the two sides of the lifting frame 31. A loudspeaker for auxiliary warning can be set here to make voice broadcasts according to the numerical deviation to assist construction personnel in fine-tuning to quickly fix it.

[0052] The angle adjustment module 44 is used to obtain the angle state of the steel corridor body 10 during the lifting process, so as to fine-tune the lifting posture of the steel corridor body 10. The angle adjustment module 44 includes an inclination sensor 4401. The inclination sensor 4401 is arranged above the steel corridor body 10. Due to the assembly and parts errors or the different gravity effects on the two lifting components 30 during the gear transmission process, the steel corridor body 10 may tilt. When the steel corridor body 10 is detected to be tilted, the operating power of the drive motors 33 on both sides is controlled based on the tilt direction, thereby modulating it to be consistent with the angle in the drawing.

[0053] The control console 41 is used to realize the control synchronization of the basic lifting control module 42, the calibration module 43 and the angle adjustment module 44.

[0054] The control console 41 is electrically connected to the driving motor 33 , the pressure sensor 4201 , the displacement sensor 4202 , the infrared sensor 4301 and the inclination sensor 4401 , respectively.

[0055] Embodiment 2

[0056] The embodiment of the present invention also discloses a method for installing a multi-layer steel structure long-span corridor, such as Figure 8 , including the following steps:

[0057] S1. Preparation before construction

[0058] Before construction, first of all, according to the requirements of the construction drawings, the connectors 50 are embedded in the floor. These connectors 50 will serve as fixing points between the subsequent steel corridor body 10 and the floor wall. At the same time, the installation position of the track assembly 20 and the initial assembly position of the steel corridor body 10 on the ground need to be determined.

[0059] S2. Track assembly 20 laying

[0060] After determining the installation position of the track assembly 20, the laying work of the track assembly 20 begins. The track assembly 20 is fixed to the wall by tension screws to ensure that it will not shift or loosen during the subsequent construction process. After the laying is completed, the structural strength of the track assembly 20 needs to be tested to ensure that it can withstand the huge load during the lifting process of the steel corridor body 10.

[0061] S3, Steel Corridor Body 10 Assembly

[0062] At the initial assembly position of the steel corridor body 10, multiple levels of steel corridor bodies 10 are arranged outward in sequence from high level to low level. At the same time, a movable tire frame is set at the bottom of each steel corridor body 10 as an auxiliary support tool to facilitate the movement of the subsequently assembled steel corridor body 10.

[0063] S4, installation of lifting assembly 30

[0064] Lifting assemblies 30 are installed on both sides of the steel corridor body 10, and these lifting assemblies 30 are respectively set on the track assemblies 20 on the buildings on both sides. The installation of the lifting assemblies 30 needs to ensure that they fit closely with the track assemblies 20 and run smoothly. At the same time, various functions of the lifting assemblies 30 need to be tested to ensure that they can start, stop and run normally.

[0065] S5. Initial position calibration

[0066] After the lifting assembly 30 is installed, the position calibration of the steel corridor body 10 is performed based on the infrared sensor 4301. The infrared sensor 4301 can accurately measure the position of the steel corridor body 10 on the lifting assembly 30, thereby ensuring that the two ends of the steel corridor body 10 and the pre-buried connectors 50 on the wall are in the same vertical position. After the calibration is completed, the steel corridor body 10 is finally fixed by the corridor clamp 34 on the lifting assembly 30 to prevent shaking or falling off during the lifting process.

[0067] S6, steel corridor main body 10 promotion

[0068] The lifting components 30 on both sides are started through the basic lifting control module 42, so that the steel corridor body 10 can be smoothly moved to the target position along the track component 20. When the displacement sensor 4202 detects that the steel corridor body 10 has moved to the target position, it sends a signal to the control console 41 to control the drive motor 33 to stop running, and fixes the steel corridor body 10 to the floor wall through the embedded connecting parts 50.

[0069] S7, Dynamic Calibration

[0070] During the lifting process of the steel corridor body 10, the angle inclination data is obtained in real time through the angle adjustment module 44. These data can reflect the posture changes of the steel corridor body 10 during the lifting process, so as to timely discover and correct possible deviations. According to the angle inclination data, the power of the two drive motors 33 is controlled respectively to correct the angle posture of the steel corridor body 10 to ensure that it always maintains an angle and posture consistent with the requirements of the construction drawings.

[0071] S8. Installation of the steel corridor body 10 at the subsequent levels

[0072] After completing the installation of the steel corridor body 10 of the current level, move the steel corridor body 10 of the subsequent level to the initial assembly position, and repeat the process from step 4 to step 7. During the repetitive process, special attention should be paid to the connection and fixing method between the steel corridor bodies 10 of each level to ensure the stability and safety of the entire corridor structure.
