Description

Technical Field

[0001] The invention relates to parking equipment, in particular to a suspended underground three-dimensional parking garage. Background Art

[0002] With the rapid growth of car ownership, parking has become an important problem in urban development. Vertical circulation parking garages are gaining more and more attention due to their advantages such as small footprint, high land space utilization, and flexible layout. Usually, vertical circulation parking garages use the front main frame and the rear main frame that are relatively arranged longitudinally (in the direction of car entry and exit) as the main bearing structure. The front main frame and the rear main frame are supported by columns fixed on the ground to extend to a predetermined height so that vehicles can be parked in the height space above the ground.

[0003] However, the vertical circulation stereo parking garage arranged on the ground needs to occupy the space above the ground, which may not be applicable in some scenarios (for example, the space above the ground has been occupied). In addition, the vertical circulation stereo parking garage arranged in this way is easy to affect the lighting of nearby buildings, and has certain requirements for the layout position. To this end, the prior art proposes a solution to set the vertical circulation stereo parking garage in a pit, and avoids occupying the ground space by fixing its front and rear main frames and other bearing structures in the pit. In addition, in order to facilitate the car to enter the car loading plate at the highest parking position and avoid occupying the ground space as much as possible, the car loading plate can be set to a supporting anti-dumping design, thereby avoiding the occupation of the ground space by the front and rear main frames and the hanging basket stable track. However, in actual application, the car loading plate with an anti-dumping design requires complex and precise structural modifications to the stabilizing rollers and guide rails, and it is difficult to always ensure the horizontal state of the parking position during the circular operation. It has high requirements for the rigidity of the bearing structures such as the front and rear main frames, and the steel structure is complex. The strength, precision and matching requirements of the rollers and guide rails are high, otherwise there is a great risk of the car tipping over.

[0004] The prior art also proposes to use a hydraulic lifting mechanism to lift the vehicle loading plate at the highest parking position to a height flush with the ground, thereby achieving the purpose of driving the car in or out. Similarly, this requires the addition of a complex lifting device, which has poor stability and a great risk of the car tipping over during the lifting and lowering process. Summary of the invention

[0005] The present invention aims to provide an underground multi-story parking garage with a streamlined structure, stability and safety. The underground multi-story parking garage adopts a brand-new suspended load-bearing design, eliminates the front and rear main frames and other load-bearing structures in the prior art, and does not require complex structural modifications and motion control of related functional components in the garage, so that the car basket can be safely operated to a height flush with the ground and maintained in a horizontal state, so as to achieve the purpose of the car driving in or out of the parking garage and safely and smoothly moving in a circular motion for parking / taking.

[0006] In order to achieve the above-mentioned object, the present invention provides a suspended underground stereoscopic parking garage, comprising:

[0007] A shaft arranged below the ground;

[0008] A suspension bearing system, the suspension bearing system comprising a front main beam and a rear main beam fixed to the top of the shaft, and an upper gantry system fixed to the upper part of the front main beam and the rear main beam, wherein a chain bearing plate is arranged on the upper gantry system;

[0009] A traction chain, the top end of which is arranged above the ground to allow the vehicle to pass through the space surrounding it, and the top end of the traction chain is mounted on the chain bearing plate; and

[0010] A drive system includes a power unit and a chain rotary dial which is transmission-connected to the power unit and cooperates with the traction chain, so that multiple car hanging baskets connected to the traction chain can be moved between different parking positions in a circular operation area by driving the traction chain to operate.

[0011] Preferably, the front main beam and the rear main beam are connected with a suspension rod extending toward the bottom of the shaft, and the drive system is installed at the bottom end of the suspension rod so that the drive system is suspended on the front main beam and the rear main beam through the suspension rod.

[0012] Preferably, a stabilizing longitudinal beam is connected between the front main beam and the rear main beam to further stabilize the main beam structure.

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

[0014] Preferably, the shaft includes multiple precast concrete rings spliced vertically. At least some of the precast concrete rings are embedded with a plurality of attachment members exposed from their inner wall surfaces, and a traction chain track, a hanging basket stabilizing track, and / or a driving system mounting bracket are connected within the shaft through connection members connected to the attachment members. At least part of the traction chain track defines the running path of the traction chain.

[0015] Through the above technical solution, the suspended underground multi-story parking garage of the present invention takes the front main beam and the rear main beam fixed to the top of the shaft as the main load-bearing foundation. The traction chain is hung on them through the upper gantry system supported on the front main beam and the rear main beam and the chain load-bearing plate provided thereon, providing a new suspended load-bearing design structure, and thus the load-bearing structures such as the front and rear main frames in the traditional technology can be omitted. In this suspended underground multi-story parking garage, the car hanging basket, the hanging basket stabilizing track, etc. can maintain the classic hanging basket design and operation guiding mode. Without complex structural transformation and motion control, the car hanging basket can move to a height flush with the ground along with the running of the traction chain and naturally maintain a horizontal state.

[0055] The following will describe in detail the detailed implementation manners of the present invention with reference to the accompanying drawings. It should be understood that the detailed implementation manners described herein are only for explaining and illustrating the present invention, and are not used to limit the present invention.

[0056] In the present invention, unless otherwise stated, the orientation terms such as "upper, lower" generally refer to the upper and lower as shown in the reference drawings; "inner, outer" refer to the inner and outer relative to the contour of each component itself. In addition, for the convenience of clear explanation, the orientation terms "front", "rear", "left", "right" generally refer to the Figures 1 to 3 and Figure 5 front, rear, left, and right directions marked, "transverse" refers to the left and right directions, and "longitudinal" refers to the front and rear directions.

[0057] Refer to Figures 1 to 3As shown, a suspended underground multi - level parking garage according to a preferred embodiment of the present invention includes a shaft 11, a suspension bearing system, a traction chain 31, a drive system 5, etc. Among them, the shaft 11 is arranged underground and can generally be precast from concrete, for example. The bottom of the shaft 11 can be supported at a predetermined position underground (such as through the cast - in - place concrete base 12 described subsequently), and the top does not exceed the ground level. Its periphery can be compacted by means of cast - in - place concrete or backfilled earthwork, etc. A main space for parking cars is defined inside the shaft 11.

[0058] As Figures 4a to 5 and Figure 10 As shown, the suspension bearing system includes a front main cross - beam 21 and a rear main cross - beam 22 supported and fixed to the top of the shaft 11, and an upper gantry system 23 fixed above the front main cross - beam 21 and the rear main cross - beam 22. A chain bearing plate 24 is provided on the upper gantry system 23. Among them, the upper gantry system 23 can include a frame structure formed by connecting a plurality of gantry beams 231 and auxiliary rods, and mounting plates 232 are connected to the front and rear sides thereof by welding or other means. The chain bearing plate 24 can be installed on the mounting plates 232. Thus, the traction chain 31 can be hung on the chain bearing plate 24, making the suspension bearing system the main bearing foundation of the parking garage. Figure 11 Shows the connection structure of the chain bearing plate 24 on the upper gantry system 23 and the loading method of the traction chain 31 thereon. Among them, the chain bearing plate 24 can be installed on the mounting plate 232 of the upper gantry system 23 through fasteners (such as bolts passing through the strip - shaped holes described subsequently). The chain rollers of the traction chain 31 are supported on the chain bearing plate 24 so as to be able to move along the chain bearing plate 24 during the operation of the traction chain 31 and remain hung thereon.

[0059] To facilitate the entry and exit of cars from the garage, the traction chain 31 is arranged such that its top end is higher than the ground, allowing the car 100 to pass through the space surrounded by it. The drive system 5 can drive the traction chain 31 to run, enabling a plurality of car gondolas 41 connected to the traction chain 31 to move between different parking positions in the circular running area. When parking a car in or retrieving a car from a certain car gondola 41, it is only necessary to use the drive system 5 to drive the traction chain 31 to run until the car gondola 41 is located at the highest parking position, and then the car 100 can be parked on the car gondola 41 or driven out of the car gondola 41.

[0060] According to the above, the suspended underground multi - storey parking garage of the present invention takes the front main cross - beam 21 and the rear main cross - beam 22 fixed at the top of the shaft 11 as the main load - bearing foundation. The traction chain 31 is hung on the upper gantry system 23 supported on the front main cross - beam 21 and the rear main cross - beam 22 and the chain load - bearing plate 24 arranged thereon. The chain load - bearing plate 24 bears almost the weight of the traction chain 31, each car hanging basket 41 connected thereto, and the cars parked thereon, which provides a brand - new suspended load - bearing design structure, and thus the load - bearing structures such as the front and rear main frames in the traditional technology can be omitted (which will be further described in detail subsequently). In this suspended underground multi - storey parking garage, the car hanging basket, the basket stable track, etc. can maintain the classic hanging basket design and operation guiding mode, and the car hanging basket can move to a height flush with the ground and naturally maintain a horizontal state as it moves along with the traction chain without complex structural transformation and motion control.

[0061] As Figures 4a to 4c , Figure 6 shown, the front main cross - beam 21 and the rear main cross - beam 22 can be arranged opposite to each other at intervals front and rear or connected to each other as a whole through the stable longitudinal beam 26 and fixed at the top of the shaft 11. Among them, a plurality of beam piers 14 can be provided at the top of the shaft 11 so that the front main cross - beam 21 and the rear main cross - beam 22 are respectively supported on the corresponding beam piers 14. Thus, by making the length of the top surface of the beam pier 14 in the extending direction of the front main cross - beam 21 and the rear main cross - beam 22 greater than the wall thickness of the shaft 11, the load - bearing capacity of the front main cross - beam 21 and the rear main cross - beam 22 can be effectively guaranteed. In the preferred embodiment of vertically splicing the multi - layer precast concrete rings 111 into the shaft 11 (please see Figure 17 ), the beam pier 14 can be fixed on the top of the uppermost precast concrete ring 111 and can be arranged relative to the top surface of the precast concrete ring 111 to support the front main cross - beam 21 and the rear main cross - beam 22 at different height positions. As Figure 6 shown, by connecting the front main cross - beam 21 and the rear main cross - beam 22 into a whole using the stable longitudinal beam 26 at the middle position between them, the huge torsional force generated during the operation of the garage can be effectively borne to ensure stable operation.

[0062] Furthermore, as Figure 1 and Figure 3 shown, the front main cross - beam 21 and the rear main cross - beam 22 can fill the height difference and gap between the wellhead and the main cross - beam and the ground parking space through the cast - in - place concrete ring 13 around the wellhead of the shaft 11, thereby allowing the car 100 to drive into or out of the car hanging basket 41 at the high - parking position through the cast - in - place concrete ring 13. In this case, the ground described in the present invention is the top surface of the cast - in - place concrete ring 13.

[0063] As Figure 4a, the beam pier 14 can be fixed on the top surface of the precast concrete ring 111, thus eliminating the need to provide a notch at the top of the precast concrete ring 111, but a relatively thick cast-in-place concrete ring 13 needs to be provided around the wellhead of the wellbore 11; for example Figure 4b , a notch can be provided on the top surface of the precast concrete ring 111, so that the beam pier 14 can be placed in the notch, reducing the thickness of the cast-in-place concrete ring 13 and increasing the connection between the beam pier 14 and the wellbore 11; for example Figure 4c , the notch on the top surface of the precast concrete ring 111 can be arranged to accommodate the beam pier 14, the front main cross beam 21 and the rear main cross beam 22 therein, making the top surfaces of the front main cross beam 21 and the rear main cross beam 22 substantially flush with the top surface of the wellbore 11, thereby significantly reducing the thickness of the cast-in-place concrete ring 13 and further restricting the beam pier 14, the front main cross beam 21 and the rear main cross beam 22.

[0064] Typically, the suspended underground multi-story parking garage of the present invention can be provided with a traction chain track 32 and a hanging basket stabilizing track 42. The traction chain track 32 at least partially defines the running path of the traction chain 31 to keep the car hanging basket 41 moving stably during operation. Figure 12 Shows the mating structure of the traction chain 31 and the traction chain track 32 and the connection structure of the traction chain track 32 connected to the inner wall surface of the wellbore 11 through the first connecting member 113 described later. The hanging basket stabilizing track 42 can be arranged on the side corresponding to the rear main cross beam 22, and the car hanging basket 41 can be provided with stabilizing rollers mating with the hanging basket stabilizing track 42. The traction chain track 32 and the hanging basket stabilizing track 42 can be arranged to be substantially the same as in the prior art, so that their upper ends can extend beyond the ground, thereby keeping the car hanging basket 41 in a stable horizontal state when a car drives into or out of the car hanging basket 41 at the highest parking position, and no complex structural modification and motion control are required.

[0065] A plurality of attachments 112 are provided inside the wellbore 11 and exposed from its inner wall surface (please see Figure 17 ), and the traction chain track 32 and the hanging basket stabilizing track 42 can be respectively connected to the wellbore 11 through connecting members connected to these attachments 112. For example Figure 2 and Figure 5As shown, the traction chain track 32 is connected to the attachment 112 of the shaft 11 through a plurality of first connection members 113, and the hanging basket stabilizing track 42 is connected to the attachment 112 of the shaft 11 through a plurality of second connection members 114. Thus, the suspended underground multi-story parking garage of the present invention uses the inner wall of the shaft 11 as the installation foundation for the traction chain track 32 and the hanging basket stabilizing track 42, and at the same time uses the hanging bearing system (front main beam 21 and rear main beam 22, upper gantry system 23 and the chain load-bearing plate 24 thereon) fixed to the top of the shaft 11 as the main load-bearing foundation, so that traditional load-bearing structures such as the front and rear main frames can be omitted. In addition, as Figure 5 , Figure 7 and Figure 8 shown, between the traction chain tracks 32 corresponding to the same traction chain 31, transverse support rods 33 can be fixedly connected respectively, and between the transverse support rods 33 corresponding to different traction chains 31, longitudinal support rods 34 can be fixedly connected to maintain a stable track spacing.

[0066] As will be described in detail later, the shaft 11 adopted in the present invention can be vertically spliced by multiple layers of precast concrete rings 111 (please see Figure 17 ). In this case, for the convenience of construction, the used traction chain track 32 and the hanging basket stabilizing track 42 can also be respectively arranged in 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 correspond to the height of multiple precast concrete rings 111.

[0067] As Figures 7 to 9 shown, in the suspended underground multi-story parking garage of a more preferred embodiment of the present invention, the front main beam 21 and the rear main beam 22 are also respectively connected with suspension rods 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 on the front main beam 21 and the rear main beam 22 through the suspension rod 6. In Figure 7 , only two suspension rods 6 arranged at a transverse interval and connected to the rear main beam 22 are shown. It can be understood that at the corresponding positions on the front main beam 21, two corresponding suspension rods 6 can also be connected. Thus, during the operation of the drive system 5 driving the traction chain 31, it can effectively prevent the influence on the stable movement of the car hanging basket caused by large differences in the force magnitudes on both sides, such as warping deformation. In addition, although it is shown in the figure that only one suspension rod 6 is provided on each side corresponding to each traction chain 31 (traction chain track 32), the present invention is not limited thereto. For example, suspension rods 6 can be respectively arranged on both sides of each traction chain track 32, that is, the front main beam 21 and the rear main beam 22 are respectively connected with two groups (such as four) of suspension rods 6. Since the suspension rod 6 has a long extension length, to ensure that the drive system 5 is stably suspended and installed at its bottom end, the suspension rod 6 can be fixed to the attachment 112 on the inner wall of the shaft 11 at different extension positions through additional connection members.

[0068] Typically, the drive system 5 may include, for example, a power unit 51 which is a reduction motor, and a chain rotary dial 54 which is transmission-connected to the power unit 51 and cooperates with the traction chain 31, as Figures 13a to 16 shown. Among them, the periphery of the chain rotary dial 54 may be provided with rotary dial blocks 5421, and the traction chain 31 may be provided with traction chain teeth 311 for cooperating with the rotary dial blocks 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 extending path.

[0069] The power output end of the power unit 51 may be transmission-connected to the chain rotary dial 54 through a drive chain 52, and these components may be mounted on a drive system mounting bracket 55 so as to be connected to the bottom end of the boom 6. As Figure 9 shown, the drive system mounting bracket 55 may be connected to the bottom end of the boom 6 through a hanging adjustment mechanism 61, so that the tension of the traction chain 31 can be adjusted by adjusting the position of the drive system mounting bracket 55 up and down. More specifically, the hanging adjustment mechanism 61 may include a tensioning bolt 611 for adjustably connecting the drive system mounting bracket 55 to the bottom end of the boom 6 and a pressing bolt 612 screwed onto the boom 6 and abutting against the drive system mounting bracket 55, so that the position of the drive system 5 can be adjusted up and down by screwing the tensioning bolt 611, and thus the tension of the traction chain 31 can be changed. In an alternative embodiment, the hanging adjustment mechanism may also be provided at the connection between the boom 6 and the front main beam 21 and the rear main beam 22.

[0070] Among them, in order to ensure the stability of the drive system 5, as Figure 5 shown, the drive system mounting bracket 55 may be fixed to the attachment 112 on the inner wall of the shaft 11 through the third connecting member 115 in all directions of front, rear, left and right.

[0071] Referring again to Figures 13a to 16 shown, in a more preferred embodiment, the drive system 5 includes chain rotary dials 54 which are arranged in pairs and respectively cooperate with both sides of the bottom end of the traction chain 31, so that it is convenient for the traction chain 31 to be opened to an appropriate width transversely, facilitating the passage of the vehicle through the space surrounded by it, without the need to provide a single rotary dial with a relatively large radial dimension.

[0072] In Figure 13a and Figure 13bIn it, the reduction motor serving as the power unit 51 is installed at the upper position in the middle of the lateral direction of the drive system mounting bracket 55, and is connected by a drive chain 52 to the central drive wheels 53 respectively meshed with the two chain rotary dials 54. The central drive wheel 53 has a chain sprocket cooperating with the drive chain 52 and a central gear meshing with the chain rotary dial 54. The chain sprocket and the central gear can be respectively arranged on the inner and outer sides of the drive system mounting bracket 55 / or both arranged on the inner side of the drive system mounting bracket 55. Thus, the two chain rotary dials 54 cooperating with both sides of the bottom end of the traction chain 31 both constitute the active dials 54a for driving the traction chain 31 to run. It can be understood that the two central drive wheels 53 corresponding to the front and rear traction chains 31 can be connected by a transmission shaft extending longitudinally, or the transmission shaft at the other end of the output shaft of the reduction motor is connected to the gear of the rear mounting bracket of the drive system, and then connected to the rear central drive wheel 53 through a rear drive chain (see Figure 8 ), and thus rotate synchronously.

[0073] Figure 13c Schematically shows an exploded view of the mounting structure of one of the chain rotary dials 54 and the drive system mounting bracket 55. Among them, the chain rotary dial 54 used in the present invention may include a slewing bearing 541 and a dial body 542 arranged coaxially with each other. The slewing bearing 541 includes a slewing bearing inner ring 5411 fixed to the drive system mounting bracket 55 by means such as fasteners or welding and a slewing bearing outer gear ring 5412 rotatably arranged on the outer circumference of the slewing bearing inner ring 5411. The dial body 542 can be fixedly installed on the end face of the slewing bearing outer gear ring 5412 by bolts, and a rotary disc block 5421 is provided on the periphery of the dial body 542 for cooperating with the traction chain 31. Thus, the central drive wheel 53 can transmit power to the dial body 542 by meshing with the slewing bearing outer gear ring 5412 of the slewing bearing 541, and then drive the traction chain 31 to run through the dial body 542. By this setting method, the chain rotary dial 54 has a relatively compact structure and can reduce its own weight to a certain extent.

[0074] In Figure 14 the shown alternative embodiment, the reduction motor is installed on the lateral outer side (left or right) of the drive system mounting bracket 55, and is also sequentially connected by a drive chain 52 and a central drive wheel 53 to the two chain rotary dials 54 arranged symmetrically with each other. The two chain rotary dials 54 both constitute the active dials 54a for driving the traction chain 31 to run.

[0075] Figure 15 And Figure 16 respectively show other alternative embodiments, which are the same as Figures 13a to 14The difference between the embodiments shown is that the reduction motor serving as the power unit 51 is directly drivably connected to one of the chain rotary dials 54 through a drive chain 52, whereby this chain rotary dial 54 constitutes the driving dial 54a that drives the traction chain 31 to run; while the other chain rotary dial 54 only cooperates with the traction chain 31 and follows when the traction chain 31 is driven to run, constituting the driven dial 54b. In these alternative embodiments, it is necessary to respectively provide reduction motors for driving the driving dial 54a at two places, the front and the rear, of the drive system mounting bracket 55, and control them to synchronously output driving power through an electrical control method to drive the traction chains 31 on the front and rear sides to run synchronously.

[0076] In some preferred embodiments, the tension adjustment of the traction chain 31 can also be achieved by adjustably mounting the chain load-bearing plate 24 on the upper gantry system 23. Specifically, as Figure 10 shown, a jacking adjustment mechanism 25 for adjusting the mounting position of the chain load-bearing plate 24 in the vertical direction can be mounted on the mounting plate 232 of the upper gantry system 23, so as to be able to adjust the tension of the traction chain 31 by adjusting the mounting position of the chain load-bearing plate 24 up and down. More specifically, a strip-shaped hole 241 can be provided on the chain load-bearing plate 24, and it is locked and mounted to the mounting plate 232 of the upper gantry system 23 through a bolt passing through the strip-shaped hole 241. The jacking adjustment mechanism 25 can include a jacking bolt mounting plate 252 fixed to the mounting plate 232 and a jacking bolt 251 threadedly connected to the jacking bolt mounting plate 252 and abutting against the chain load-bearing plate 24. Thus, by screwing the jacking bolt 251, the up and down mounting position of the chain load-bearing plate 24 can be changed, thereby changing the tension of the traction chain 31 mounted thereon.

[0077] Figure 17 shows a cross-sectional view of the shaft 11, the cast-in-place concrete collar 13, the cast-in-place concrete foundation 12, etc. in a suspended underground multi-story parking garage according to a preferred embodiment of the present invention. In this preferred embodiment, the shaft 11 includes multiple layers of precast concrete rings 111 spliced vertically, and at least some of the precast concrete rings 111 are embedded with a plurality of attachment members 112 exposed from their inner wall surfaces, so as to connect the traction chain track 32, the hanging basket stabilizing track 42, and / or the drive system mounting bracket 55, etc. inside the shaft 11 through connection members. By splicing a plurality of precast concrete rings 111 to form the shaft 11, not only can the construction efficiency be effectively improved, but also a high dimensional accuracy can be ensured through prefabrication and molding.

[0078] Furthermore, a cast-in-place concrete foundation 12 can be provided at the bottom of the shaft 11, serving as the support foundation for each precast concrete ring 111 in the shaft 11, and at the same time being able to resist the buoyancy of groundwater. Combining Figure 18As shown, an installation boss 121 may be formed at the edge portion of the cast-in-place concrete base 12, and the bottommost precast concrete ring 111 may be supported and fixed on the installation boss 121. Additionally, a positioning boss (which may cooperate with a positioning groove formed at one end of the precast concrete ring 111 described later) and an embedded part 122 made of metal material may be provided on the top surface of the installation boss 121, so as to position and install the bottommost precast concrete ring 111 and fixedly connect it together.

[0079] In the present invention, each layer of the precast concrete rings 111 may be an integral component or composed of a plurality of precast blocks spliced together. As Figures 19a to 19d shown, in a preferred embodiment, the precast concrete ring 111 may be formed by circumferentially splicing a plurality of 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 attachment members 112. To ensure relatively high assembly stability and a certain waterproof function, the splicing joints 1115 between adjacent precast blocks 1111 may be formed as wedges inclined relative to their thickness direction, and / or the splicing joints 1115 in adjacent two layers of precast concrete rings 111 are arranged in a staggered manner, that is, the splicing seams are not on the same straight line.

[0080] In addition, bolt connectors 116, such as horizontal connection bolts and vertical connection bolts, may also be provided at the edge portions (upper and lower ends, circumferential ends) of each precast block 1111, so as to connect adjacent precast blocks 1111 and adjacent layers of precast concrete rings 111 into an integral body through these bolt connectors 116. To facilitate the installation of these bolt connectors 116, the precast block 111 (or the integral precast concrete ring 111) may be formed with installation grooves 1112 opening from its inner wall surface, so as to install fastening nuts on the horizontal connection bolts and vertical connection bolts from inside the precast concrete ring 111. In other embodiments, the installation grooves 1112 may also be formed to open from the outer wall surface of the precast concrete ring 111.

[0081] To perform edge positioning and assembly and ensure that adjacent layers of precast concrete rings 111 are hermetically joined to each other, a circumferentially extending positioning boss 1113 may be formed at one end of the precast concrete ring 111, and a circumferentially extending positioning groove 1114 may be formed at the other end, so that the positioning bosses 1113 and positioning grooves 1114 of adjacent layers of precast concrete rings 111 cooperate with each other to be hermetically positioned and spliced together.

[0082] Figures 19a to 19d The precast concrete ring 111 shown is formed by splicing four precast blocks 1111 together, including two U-shaped precast blocks and two flat precast blocks, but the present invention is not limited thereto. The precast concrete ring 111 may adopt various different block division rules, as long as the overall rigidity and dimensional accuracy after assembly are ensured. In 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. The two side lengths L1 and L2 of the corner precast blocks are not equal, so that after assembly, the joints 1115 of adjacent layers of precast concrete rings 111 are offset from each other.

[0083] Figure 21 A precast concrete ring of another preferred embodiment is provided. Different from the foregoing preferred embodiment, between two adjacent corners of the precast concrete ring, the precast block 1111 is formed into a horizontal cross-sectional shape that arches outward from the center of the precast concrete ring 111. Through this setting, the pressure from the backfill soil around the wellbore 11 can be evenly distributed, thereby ensuring the stability of the internal space.

[0084] Referring to Figure 22 and Figure 23 and

[0085] In order to facilitate people to get on and off the car when parking or retrieving the car, the suspended underground stereoscopic parking garage may also include a lateral pedestrian bridge 72 for the driver and passengers to enter the car basket 41 at the highest parking position from the ground or return to the ground from the car basket 41. The lateral pedestrian bridge 72 may be connected to the front and rear main frames or the vehicle loading plate of the car basket 41, and may be set as a translationally movable, liftable or rotatable installation structure, so as to be able to move between the working position and the avoidance position or be removed from the working position.

[0086] Refer again Figure 1 and Figure 2 As shown, the suspended underground stereoscopic parking garage of the present invention may further include a parking room or a parking shed 8 covering the shaft 11 and the upper door frame system 23, thereby improving safety and providing rain protection and other functions.
