Description

Technical Field

[0001] This utility model relates to parking equipment, specifically to a suspended underground multi-level parking garage. Background Technology

[0002] With the rapid growth of car ownership, parking difficulties have become a significant challenge in urbanization. Vertical circulation parking garages are gaining increasing attention due to their advantages such as small footprint, high land space utilization, and flexible layout. Typically, vertical circulation parking garages use a front main frame and a rear main frame arranged longitudinally (in the direction of vehicle entry and exit) as the main load-bearing structures. These front and rear main frames are supported by columns fixed to the ground and extend to a predetermined height to utilize the vertical space above ground for vehicle parking.

[0003] However, vertical circulating parking garages located on the ground require space above ground, which may be unsuitable in some scenarios (e.g., when above-ground space is already occupied). Furthermore, this type of vertical circulating parking garage can easily affect the lighting of nearby buildings, placing certain requirements on its location. To address this, existing technologies propose a solution where the vertical circulating parking garage is placed in a pit, thus avoiding the occupation of above-ground space by fixing its front and rear main frames and other load-bearing structures within the pit. Moreover, to facilitate vehicle entry into the car carrier platform located at the highest parking position and to minimize the occupation of above-ground space, the car carrier platform can be designed with a supported anti-tipping mechanism, thereby avoiding the occupation of above-ground space by the front and rear main frames and the stabilizing rails. However, in practical applications, the anti-tipping design of the car carrier platform requires complex and precise structural modifications to the stabilizing rollers and guide rails. It is difficult to maintain the horizontal state of the parking position at all times during circular operation, and high rigidity is required for the front and rear main frames and other load-bearing structures. The steel structure is complex, and the strength, precision, and fit of the rollers and guide rails are highly demanding; otherwise, there is a significant risk of vehicle tipping over.

[0004] Existing technologies also propose using a hydraulic lifting mechanism to raise the vehicle platform at the highest parking position to a height level with the ground, thereby enabling vehicles to drive in or out. However, this requires a complex lifting device, has poor stability, and poses a significant risk of vehicle tipping over during lifting and lowering. Utility Model Content

[0005] This utility model aims to provide a simplified, stable, and safe underground multi-level parking garage. The underground multi-level parking garage adopts a brand-new suspended load-bearing design, eliminating the front and rear main frames and other load-bearing structures in the existing technology. It can safely move the car basket to the same height as the ground and maintain a horizontal state without the need for complex structural modifications and motion control of the relevant functional components in the garage, so as to realize the purpose of parking / retrieving cars by driving into or out of the parking garage and moving safely and smoothly in a circumferential direction.

[0006] To achieve the above objectives, this utility model provides a suspended underground multi-level parking garage, comprising:

[0007] A well shaft, which is located underground;

[0008] The suspended load-bearing system includes a front main crossbeam and a rear main crossbeam fixed to the top of the well shaft, and an upper gantry system fixed above the front main crossbeam and the rear main crossbeam, wherein a chain load-bearing plate is provided on the upper gantry system.

[0009] A traction chain, the traction chain being arranged such that its top is above the ground to allow a vehicle to pass through the space it surrounds, and the top of the traction chain being mounted on the chain support plate; and

[0010] A drive system comprising a power unit and a chain rotary dial connected to the power unit and cooperating with the traction chain, enabling multiple truck baskets connected to the traction chain to move between different parking positions within a circular operating area by driving the traction chain.

[0011] Preferably, the front main crossbeam and the rear main crossbeam are connected to a boom extending toward the bottom of the wellbore, and the drive system is installed at the bottom end of the boom so that the drive system is suspended from the front main crossbeam and the rear main crossbeam by the boom.

[0012] Preferably, a stabilizing longitudinal beam connects the front main crossbeam and the rear main crossbeam to further stabilize the main crossbeam structure.

[0013] Preferably, the drive system includes a pair of chain rotary dials respectively configured to cooperate with the bottom two sides of the traction chain, wherein the chain rotary dial may include a rotary bearing and a dial body arranged coaxially with each other, the rotary bearing includes a rotary bearing inner ring fixed on the drive system mounting frame and a rotary bearing outer gear ring rotatably disposed on the outer periphery of the rotary bearing inner ring, and the dial body is fixedly mounted to the end face of the rotary bearing outer gear ring.

[0014] Preferably, the well shaft includes vertically spliced ​​multi-layer precast concrete rings, at least a portion of which are pre-embedded with multiple attachments exposed from their inner wall surfaces, and a traction chain track, a basket stabilizing track, and / or a drive system mounting frame are connected within the well shaft via connecting members connected to the attachments, the traction chain track at least partially defining the running path of the traction chain.

[0015] Through the above technical solution, the suspended underground multi-level parking garage of this utility model uses the front and rear main crossbeams fixed to the top of the shaft as the main load-bearing foundation. The traction chain is suspended on the upper gantry system supported on these main crossbeams and the chain support plate mounted on them, providing a completely new suspended load-bearing design structure. This eliminates the need for the front and rear main frames and other load-bearing structures found in traditional technologies. In this suspended underground multi-level parking garage, the car basket and its stabilizing rails can maintain the classic basket-style design and operation guidance method. Without complex structural modifications or motion control, the car basket can move to ground level with the traction chain and naturally maintain a horizontal state. Attached Figure Description

[0055] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0056] In this utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer positions relative to the contours of each component itself. Furthermore, for clarity, directional terms such as "front," "rear," "left," and "right" generally refer to the positions shown in the accompanying drawings. Figures 1 to 3 as well as Figure 5 The markings indicate the front, back, left, and right directions. "Horizontal" refers to the left-right direction, and "vertical" refers to the front-back direction.

[0057] Reference Figures 1 to 3As shown, a suspended underground parking garage according to a preferred embodiment of the present invention includes a shaft 11, a suspension support system, a traction chain 31, and a drive system 5. The shaft 11 is located underground and is typically made of precast concrete. The bottom of the shaft 11 is supported at a predetermined location underground (e.g., via a cast-in-place concrete base 12 described later), and the top does not exceed ground level. Its perimeter can be compacted by cast-in-place concrete or backfill. The shaft 11 defines the main space for parking cars.

[0058] like Figures 4a to 5 and Figure 10 As shown, the suspended load-bearing system includes a front main crossbeam 21 and a rear main crossbeam 22 supported and fixed to the top of the shaft 11, and an upper gantry system 23 fixed above the front and rear main crossbeams 21 and 22. A chain support plate 24 is provided on the upper gantry system 23. The upper gantry system 23 may include a frame structure formed by interconnecting multiple gantry beams 231 and auxiliary rods, and mounting plates 232 are connected to its front and rear sides by welding or other means. The chain support plate 24 can be installed on the mounting plate 232. Thus, the traction chain 31 can be mounted on the chain support plate 24, making the suspended load-bearing system the main load-bearing foundation of the parking garage. Figure 11 The connection structure of the chain support plate 24 to the upper gantry system 23 and the bearing method of the traction chain 31 thereon are shown. The chain support plate 24 can be installed on the mounting plate 232 of the upper gantry system 23 by fasteners (such as bolts through the strip holes as described later). The chain rollers of the traction chain 31 are supported on the chain support plate 24 so that the traction chain 31 can move along the chain support plate 24 and remain mounted thereon during operation.

[0059] To facilitate vehicle entry and exit from the garage, the traction chain 31 is positioned with its top end above the ground, allowing the vehicle 100 to traverse the space it surrounds. The drive system 5 enables the movement of multiple car baskets 41 connected to the traction chain 31 between different parking positions within the circular operating area by driving the traction chain 31. When parking or retrieving a car from a particular car basket 41, the vehicle 100 can be parked on or driven off the car basket 41 simply by using the drive system 5 to drive the traction chain 31 to the highest parking position.

[0060] Based on the above, the suspended underground multi-level parking garage of this utility model uses the front main crossbeam 21 and the rear main crossbeam 22 fixed to the top of the shaft 11 as the main load-bearing foundation. The traction chain 31 is suspended on the upper gantry system 23 supported on the front main crossbeam 21 and the rear main crossbeam 22 and the chain support plate 24 set on it. The chain support plate 24 almost bears the weight of the traction chain 31, the various car baskets 41 connected to it, and the cars parked on it. This provides a brand-new suspended load-bearing design structure, and thus eliminates the need for the front and rear main frames and other load-bearing structures in the traditional technology (which will be further detailed later). In this suspended underground multi-level parking garage, the car baskets, basket stabilizing rails, etc. can maintain the classic basket design and operation guidance method. Without complex structural modifications and motion control, the car baskets can move to the height of the ground with the operation of the traction chain and naturally maintain a horizontal state.

[0061] like Figures 4a to 4c , Figure 6 As shown, the front main crossbeam 21 and the rear main crossbeam 22 can be arranged opposite each other at intervals or connected to each other as a whole by a stabilizing longitudinal beam 26 and fixed to the top of the shaft 11. The top of the shaft 11 can be provided with multiple beam piers 14, so that the front main crossbeam 21 and the rear main crossbeam 22 are respectively supported on the corresponding beam piers 14. Therefore, by ensuring that the length of the top surface of the beam pier 14 along the extension direction of the front main crossbeam 21 and the rear main crossbeam 22 is greater than the wall thickness of the shaft 11, the load-bearing capacity of the front main crossbeam 21 and the rear main crossbeam 22 can be effectively guaranteed. The shaft 11 is formed by vertically splicing multiple layers of precast concrete rings 111, as detailed later (see below). Figure 17 In a preferred embodiment, the beam pier 14 can be fixed to the top of the uppermost precast concrete ring 111, and can be configured to support the front main crossbeam 21 and the rear main crossbeam 22 at different heights relative to the top surface of the precast concrete ring 111. Figure 6 As shown, by using a stabilizing longitudinal beam 26 to connect the front main crossbeam 21 and the rear main crossbeam 22 at the middle position, the huge torsional force generated during garage operation can be effectively withstood, ensuring stable operation.

[0062] Furthermore, such as Figure 1 and Figure 3 The front main crossbeam 21 and the rear main crossbeam 22 can be filled with a cast-in-place concrete ring 13 surrounding the manhole opening of the shaft 11 to fill the height difference and gap between the manhole opening and the main crossbeam and the ground parking space, thereby allowing the car 100 to drive into or out of the car basket 41 at the high parking position through the cast-in-place concrete ring 13. In this case, the ground described in this utility model is the top surface of the cast-in-place concrete ring 13.

[0063] like Figure 4aThe beam pier 14 can be fixed to the top surface of the precast concrete ring 111, thus eliminating the need for a notch at the top of the precast concrete ring 111. However, a relatively thick cast-in-place concrete ring 13 needs to be provided around the wellhead of the shaft 11. Figure 4b A notch can be provided on the top surface of the precast concrete ring 111, allowing the beam pier 14 to be placed within the notch. This reduces the thickness of the cast-in-place concrete ring 13 and increases the connection between the beam pier 14 and the well shaft 11. Figure 4c The notch on the top surface of the precast concrete ring 111 can be designed to accommodate the beam pier 14, the front main crossbeam 21 and the rear main crossbeam 22, so that the top surfaces of the front main crossbeam 21 and the rear main crossbeam 22 are basically flush with the top surface of the shaft 11. This can significantly reduce the thickness of the cast-in-place concrete ring 13 and further restrict the beam pier 14 and the front main crossbeam 21 and the rear main crossbeam 22.

[0064] Typically, the suspended underground parking garage of this invention may be equipped with a traction chain track 32 and a basket stabilizing track 42. The traction chain track 32 at least partially defines the running path of the traction chain 31 so as to keep the car basket 41 moving stably during operation. Figure 12 The diagram illustrates the mating structure of the traction chain 31 and the traction chain track 32, as well as the connection structure of the traction chain track 32 to the inner wall of the shaft 11 via the first connecting member 113, described later. A stabilizing track 42 can be positioned on the side corresponding to the rear main crossbeam 22, and the truck basket 41 can be equipped with stabilizing rollers that mate with the stabilizing track 42. The traction chain track 32 and the stabilizing track 42 can be configured in a manner largely consistent with conventional technology, whereby their upper ends can extend beyond the ground, thereby maintaining the truck basket 41 in a stable horizontal state when the vehicle enters or exits the highest parking position, without requiring complex structural modifications or motion control.

[0065] The well casing 11 is provided with a plurality of attachments 112 exposed from its inner wall surface (see Figure 17 The traction chain track 32 and the basket stabilizing track 42 can be connected to the wellbore 11 via connecting members that are connected to these attachments 112. Figure 2 and Figure 5As shown, the traction chain track 32 is connected to the attachment 112 of the shaft 11 via multiple first connecting members 113, and the suspended basket stabilizing track 42 is connected to the attachment 112 of the shaft 11 via multiple second connecting members 114. Therefore, the suspended underground parking garage of this invention uses the inner wall of the shaft 11 as the installation foundation for the traction chain track 32 and the suspended basket stabilizing track 42, while using the suspended load-bearing system (front main crossbeam 21 and rear main crossbeam 22, upper gantry system 23 and its chain bearing plate 24) fixed to the top of the shaft 11 as the main load-bearing foundation, thus eliminating the need for traditional load-bearing structures such as front and rear main frames. Furthermore, as... Figure 5 , Figure 7 and Figure 8 As shown, transverse support rods 33 can be fixedly connected between the traction chain tracks 32 corresponding to the same traction chain 31, and longitudinal support rods 34 can be fixedly connected between the transverse support rods 33 corresponding to different traction chains 31 to maintain a stable track spacing.

[0066] As will be detailed later, the well shaft 11 used in this utility model can be vertically spliced ​​together from multiple layers of precast concrete rings 111 (see below). Figure 17 In this case, for ease of construction, the traction chain track 32 and the scaffolding stabilizing track 42 can also be set as multiple segments connected to each other, and the length of each segment can correspond to the height of a single precast concrete ring 111 or the height of multiple precast concrete rings 111.

[0067] like Figures 7 to 9 As shown, in a preferred embodiment of the suspended underground multi-level parking garage of this utility model, the front main crossbeam 21 and the rear main crossbeam 22 are respectively connected to a suspension rod 6 extending towards the bottom of the shaft 11, and the drive system 5 is installed at the bottom end of the suspension rod 6, so that the drive system 5 is suspended from the front main crossbeam 21 and the rear main crossbeam 22 by the suspension rod 6. Figure 7 The diagram only shows two booms 6 arranged laterally and connected to the rear main crossbeam 22. It can be understood that two booms 6 can also be connected at corresponding positions on the front main crossbeam 21. Therefore, during the operation of the drive system 5 driving the traction chain 31, warping and deformation caused by significant differences in force on both sides can be effectively prevented from affecting the stable movement of the truck basket. Furthermore, although the diagram shows only one boom 6 on each side of each traction chain 31 (traction chain track 32), the invention is not limited to this. For example, booms 6 can be provided on both sides of each traction chain track 32, meaning that the front main crossbeam 21 and the rear main crossbeam 22 are each connected to two sets (e.g., four booms) of booms 6. Since the booms 6 have a relatively long extension length, to ensure that the drive system 5 is stably suspended and installed at its bottom, additional connecting components can be used to fix them to the attachments 112 on the inner wall of the shaft 11 at different extension positions.

[0068] Typically, the drive system 5 may include, for example, a power unit 51, a geared motor, and a chain rotary dial 54 that is driveably connected to the power unit 51 and engages with the traction chain 31, such as... Figures 13a to 16 As shown. The chain rotary dial 54 may be provided with a rotary dial block 5421 around its periphery, and the traction chain 31 may be provided with a traction chain tooth 311 for cooperating with the rotary dial block 5421. Thus, when the chain rotary dial 54 is driven to rotate, the traction chain 31 receives the power transmitted by it and is driven to run within its extended path.

[0069] The power output of the power unit 51 can be driven by the drive chain 52 to the chain rotary dial 54. These components can be mounted on the drive system mounting bracket 55 for connection to the bottom end of the boom 6. Figure 9 As shown, the drive system mounting bracket 55 can be connected to the bottom end of the boom 6 via a suspension adjustment mechanism 61, thereby allowing the tension of the traction chain 31 to be adjusted by vertically adjusting the position of the drive system mounting bracket 55. More specifically, the suspension adjustment mechanism 61 may include a tension bolt 611 for adjustablely connecting the drive system mounting bracket 55 to the bottom end of the boom 6 and a locking bolt 612 screwed to the boom 6 and abutting against the drive system mounting bracket 55, thereby allowing the position of the drive system 5 to be adjusted vertically by tightening the tension bolt 611, thus changing the tension of the traction chain 31. In an alternative embodiment, the suspension adjustment mechanism may also be located at the connection between the boom 6 and the front main crossbeam 21 and the rear main crossbeam 22.

[0070] In order to ensure the stability of drive system 5, such as Figure 5 As shown, the drive system mounting bracket 55 can be distributed in the front, rear, left and right directions and fixed to the attachments 112 on the inner wall of the well barrel 11 by the third connecting member 115.

[0071] Refer again Figures 13a to 16 As shown, in a preferred embodiment, the drive system 5 includes a pair of chain rotary dials 54 that are respectively configured to engage with the bottom sides of the traction chain 31, thereby facilitating the traction chain 31 to be opened laterally to an appropriate width, allowing the vehicle to pass through the space it surrounds, without the need for a single rotary dial with a large radial dimension.

[0072] exist Figure 13a and Figure 13bIn this configuration, the geared motor, serving as the power unit 51, is mounted above the transverse center of the drive system mounting bracket 55. It is connected via a drive chain 52 to central drive wheels 53, which mesh with two chain rotary dials 54. Each central drive wheel 53 has a chain disc that engages with the drive chain 52 and a central gear that meshes with the chain rotary dials 54. The chain disc and central gear can be located on the inner and outer sides of the drive system mounting bracket 55, or both can be located on the inner side of the drive system mounting bracket 55. Thus, the two chain rotary dials 54, which engage with the bottom ends of the traction chain 31, constitute the active dials 54a that drive the traction chain 31. It is understood that the two central drive wheels 53 corresponding to the front and rear sides of the traction chain 31 can be connected via a longitudinally extending drive shaft, or the drive shaft at the other end of the geared motor output shaft can be connected to a gear on the rear mounting bracket of the drive system, and then connected to the rear central drive wheel 53 via the rear drive chain (see...). Figure 8 ), thus rotating synchronously.

[0073] Figure 13c An exploded view schematically illustrates the installation structure of one of the chain rotary dials 54 and the drive system mounting bracket 55. The chain rotary dial 54 used in this invention may include a slewing bearing 541 and a dial body 542 arranged coaxially. The slewing bearing 541 includes an inner slewing bearing ring 5411 fixed to the drive system mounting bracket 55 by fasteners or welding, and an outer slewing bearing gear ring 5412 rotatably disposed on the outer periphery of the inner slewing bearing ring 5411. The dial body 542 may be bolted to the end face of the outer slewing bearing gear ring 5412, and a rotary dial block 5421 is provided around the periphery of the dial body 542 for engagement with the traction chain 31. Thus, the central drive wheel 53 can transmit power to the dial body 542 by meshing with the outer slewing bearing gear ring 5412 of the slewing bearing 541, thereby driving the traction chain 31 through the dial body 542. With this configuration, the chain rotary dial 54 has a relatively compact structure and can reduce its weight to some extent.

[0074] exist Figure 14 In the alternative embodiment shown, the geared motor is mounted on the lateral outer side (left or right side) of the drive system mounting bracket 55, and is also connected in sequence to two chain rotary dials 54 arranged symmetrically to each other via the drive chain 52 and the central drive wheel 53. Both chain rotary dials 54 constitute active dials 54a that drive the traction chain 31.

[0075] Figure 15 and Figure 16 Other alternative implementations are shown, which are similar to... Figures 13a to 14The difference in the illustrated implementation is that the geared motor, serving as the power unit 51, is directly connected to one of the chain rotary dials 54 via a drive chain 52. This chain rotary dial 54 thus constitutes the active dial 54a that drives the traction chain 31. The other chain rotary dial 54 only cooperates with the traction chain 31 and follows its movement when the traction chain 31 is driven, constituting the driven dial 54b. In these alternative implementations, geared motors for driving the active dial 54a are installed at both the front and rear of the drive system mounting bracket 55, and these motors are electrically controlled to output synchronous drive power to drive the traction chains 31 on both the front and rear sides synchronously.

[0076] In some preferred embodiments, the tension of the traction chain 31 can also be adjusted by adjusting the chain support plate 24 to be mounted on the upper gantry system 23. Specifically, such as Figure 10 As shown, a lifting adjustment mechanism 25 for vertically adjusting the installation position of the chain support plate 24 can be installed on the mounting plate 232 of the upper gantry system 23, so that the tension of the traction chain 31 can be adjusted by adjusting the installation position of the chain support plate 24. More specifically, the chain support plate 24 may be provided with a strip hole 241, and is locked to the mounting plate 232 of the upper gantry system 23 by bolts passing through the strip hole 241. The lifting adjustment mechanism 25 may include a lifting bolt mounting plate 252 fixed to the mounting plate 232 and a lifting bolt 251 threaded to the lifting bolt mounting plate 252 and abutting against the chain support plate 24. Thus, by turning the lifting bolt 251, the vertical installation position of the chain support plate 24 can be changed, thereby changing the tension of the traction chain 31 mounted on it.

[0077] Figure 17 A cross-sectional view of a suspended underground parking garage, including a shaft 11, a cast-in-place concrete ring 13, and a cast-in-place concrete base 12, is shown according to a preferred embodiment of the present invention. In this preferred embodiment, the shaft 11 comprises vertically spliced ​​multi-layered precast concrete rings 111, at least some of which have multiple attachments 112 exposed from their inner walls for connecting traction chain rails 32, suspended platform stabilizing rails 42, and / or drive system mounting frames 55 within the shaft 11 via connecting members. By splicing multiple precast concrete rings 111 together to form the shaft 11, construction efficiency can be effectively improved, and high dimensional accuracy can be ensured through pre-molding.

[0078] Furthermore, a cast-in-place concrete base 12 can be provided at the bottom of the well shaft 11 to serve as the supporting foundation for each precast concrete ring 111 within the well shaft 11, while also resisting the buoyancy of groundwater. Combined with... Figure 18As shown, the edge of the cast-in-place concrete base 12 can be formed with a mounting boss 121, and the bottom precast concrete ring 111 can be supported and fixed on the mounting boss 121. In addition, the top surface of the mounting boss 121 can be provided with a positioning boss (which can cooperate with the positioning groove formed at one end of the precast concrete ring 111 as described later) and a metal embedded part 122, so as to position and install the bottom precast concrete ring 111 and fix it together.

[0079] In this invention, each layer of precast concrete ring 111 can be a single integral component or composed of multiple precast blocks assembled together. For example... Figures 19a to 19d As shown, in a preferred embodiment, the precast concrete ring 111 can be formed by circumferentially splicing multiple precast blocks 1111 together, thereby further improving the convenience of material transportation and on-site assembly. At least some of the precast blocks 1111 are provided with attachments 112. To ensure high assembly stability and a certain degree of waterproofing, the splicing interface 1115 of adjacent precast blocks 1111 can be formed as a wedge shape inclined relative to its thickness direction, and / or, the splicing interfaces 1115 in two adjacent layers of precast concrete rings 111 are staggered, i.e., the splicing seams are not on the same straight line.

[0080] Additionally, bolted connectors 116, such as horizontal and vertical connecting bolts, can be provided at the edges (upper and lower ends, circumferential ends) of each precast block 1111 to connect adjacent precast blocks 1111 and adjacent layers of precast concrete rings 111 into a single unit. To facilitate the installation of these bolted connectors 116, the precast block 111 (or the integral precast concrete ring 111) can be formed with mounting grooves 1112 opening from its inner wall surface, allowing for the installation of fastening nuts from within the precast concrete ring 111 on the horizontal and vertical connecting bolts. In other embodiments, the mounting grooves 1112 can also be formed opening from the outer wall surface of the precast concrete ring 111.

[0081] In order to position the precast concrete rings 111 of adjacent layers for edge positioning and ensure that they are sealed together, a positioning boss 1113 extending circumferentially can be formed at one end of the precast concrete ring 111, and a positioning groove 1114 extending circumferentially can be formed at the other end. Thus, the positioning boss 1113 and the positioning groove 1114 of the precast concrete rings 111 of adjacent layers are mutually engaged to seal and position them together.

[0082] Figures 19a to 19d The precast concrete ring 111 shown is composed of four precast blocks 1111 spliced ​​together, including two U-shaped precast blocks and two flat precast blocks. However, this utility model is not limited to this; the precast concrete ring 111 can adopt various different segmentation rules, as long as the overall rigidity and dimensional accuracy after assembly are guaranteed. Figure 20In the alternative embodiment shown, the precast concrete ring 111 includes eight precast blocks 1111, namely four flat precast blocks and four corner precast blocks, and the two side lengths L1 and L2 of the corner precast blocks are not equal, so that the splicing interface 1115 of the precast concrete rings 111 of adjacent layers can be misaligned after assembly.

[0083] Figure 21 Another preferred embodiment of the precast concrete ring is provided. Unlike the aforementioned preferred embodiment, between two adjacent corners of this precast concrete ring, the precast blocks 1111 are formed with a horizontal cross-sectional shape that arches outward from the center of the precast concrete ring 111. This arrangement allows the pressure from the backfill soil on the manhole 11 to be evenly distributed, thereby ensuring the stability of the internal space.

[0084] Reference Figure 22 and Figure 23 The suspended underground parking garage of this utility model may further include a longitudinal vehicle bridge 71 for a car 100 to drive from the ground into and / or out of the car basket 41 located at the highest parking position. The longitudinal vehicle bridge 71 may be connected to the aforementioned front main crossbeam 21 for entry or exit from the front. In an embodiment where entry is from the front and exit is from the rear, the longitudinal vehicle bridge 71 may also be connected to the rear main crossbeam 22. The longitudinal vehicle bridge 71 is configured to be flush with the ground and the vehicle platform of the car basket 41, thereby preventing the car from getting stuck in the gap between the vehicle platform and the ground during entry and exit. To avoid interfering with the operation of the parking garage, the longitudinal vehicle bridge 71 may be configured to move between a working position and an avoidance position or be removed from the working position, for example, configured as a translatable, liftable, or rotatable mounting structure. In addition, the longitudinal vehicle crossing plate 71 and the lateral pedestrian crossing plate 72, as described later, can be configured to be linked and controlled with the car basket 41 or the garage safety door (such as the parking room or parking shed described later). That is, before the car basket 41 is driven to move, or after the personnel leave the garage safety door, the longitudinal vehicle crossing plate 71 and the lateral pedestrian crossing plate 72 move to the avoidance position so that the car basket 41 can move between the highest parking position and other parking positions; when the corresponding car basket 41 moves to the highest parking position and stops to retrieve the vehicle, or before or at the same time as the garage safety door is opened, the longitudinal vehicle crossing plate 71 and the lateral pedestrian crossing plate 72 move to the working position.

[0085] To facilitate getting on and off vehicles, the suspended underground parking garage may also include lateral pedestrian bridges 72 for drivers and passengers to enter the car basket 41 located at the highest parking position from the ground or return from the car basket 41 to the ground. These lateral pedestrian bridges 72 can be connected to the front and rear main frames or the vehicle platform of the car basket 41, and can be configured as a sliding, lifting, or rotating installation structure to allow movement between working and avoidance positions or removal from the working position.

[0086] Refer again Figure 1 and Figure 2 As shown, the suspended underground parking garage of this utility model may also include a parking room or parking shed 8 that covers the shaft 11 and the upper gantry system 23, thereby improving safety and providing functions such as rain protection.

[0087] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, including combinations of various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
