Description

Technical Field

[0001] The present invention relates to the technical field of the assembly of steel structure garages, and particularly relates to a modular prefabricated steel structure garage. Background Art

[0002] With the rapid increase in the urban car ownership, the problem of parking difficulty has become increasingly prominent. Traditional reinforced concrete garages have a long construction period, a large amount of on-site wet work, a large amount of construction waste, and high requirements for the site environment. For this reason, prefabricated steel structure garages have emerged, which have the advantages of fast construction, light weight, environmental protection, etc.

[0003] For example, Chinese Patent No. CN208604992U discloses a prefabricated self-driving garage, including a pair of H-shaped frame structures composed of structural main beams and structural columns. Among them, a structural main beam is horizontally arranged between every two structural columns, and the structural columns play a supporting role. A number of structural secondary beams are horizontally arranged between the two structural main beams. The structural main beams, structural secondary beams, and structural columns together form a complete garage frame. A steel grating is arranged on the plane formed by the structural main beams, structural secondary beams, and structural columns. A connecting plate is arranged at the connection position between the structural main beam and the structural column. The connecting plate is of a "convex" shape structure, and the "convex" shape structure includes a protruding end and a tail end. The protruding end of the connecting plate is connected to the structural main beam, and the tail end of the connecting plate is connected to the structural column. The connecting plate is connected to the structural main beam and the structural column through bolts.

[0004] However, there are still some deficiencies in the above modular prefabricated steel structure garage during actual use:

[0005] 1. The above existing traditional steel structure garages generally rely on welding or bolt perforation for assembly. During this process, metal components are prone to distortion under the high temperature state of welding, thus affecting the strength of the metal components. If bolt assembly is used, stress concentration will occur in the metal components near the bolt due to the extrusion of the bolt and nut at the perforation. At the same time, the repeated disassembly and assembly of the bolt accelerate the stress fluctuation at the connection hole until the metal component is deformed, thereby shortening the service life of the metal component.

[0006] 2. In addition, the existing steel structure garages usually use chain and sprocket to achieve lifting, and their stability is poor. Moreover, the existing lifting mechanism lacks a reliable self-locking device, and the periodic vibration generated when the vehicle enters and exits is likely to cause structural settlement, resulting in the instability of the garage height and potential safety hazards.

[0007] Therefore, under the above-mentioned viewpoints, there is still room for improvement in the existing modular prefabricated steel structure garage. Summary of the Invention

[0008] In order to solve the above problems, the present invention provides a modular prefabricated steel structure garage, adopting the following technical solutions:

[0009] A modular prefabricated steel structure garage includes four rectangular crossbeams, I-beam longitudinal beams that are matched and connected to the crossbeams, and connectors between the crossbeams and the longitudinal beams.

[0017] The strip slider has a working groove for the adjustment gear to rotate. The adjustment gear is in movable engagement with the limiting rack. The limiting rod is slidably inserted into the strip slider, and one end of the limiting rod extends toward the limiting rack. Several insertion interfaces for the limiting rod to be inserted are equally spaced on the limiting rack.

[0018] Preferably, the strip slider has a countersunk hole for the insertion of the limiting rod, and the countersunk hole of the strip slider is provided with two sets of symmetrical snap-fit ​​springs, and the top of the limiting rod is provided with a snap-fit ​​interface corresponding to the snap-fit ​​springs.

[0019] Preferably, the connector includes several right-angle connecting seats that are interference-fitted with the I-beam crossbeam and the I-beam longitudinal beam, limiting pins that limit the right-angle connecting seats, the I-beam crossbeam and the I-beam longitudinal beam, and limiting pull rings to prevent the limiting pins from falling off.

[0020] The right-angle connector has an installation groove for interference fit installation of the I-beam crossbeam and the I-beam longitudinal beam. The two ends of the right-angle connector, the two ends of the I-beam crossbeam, and the two ends of the I-beam longitudinal beam are all provided with the same limiting holes for the assembly of the limiting pin. The two ends of the limiting pin are provided with anti-drop holes for the assembly of the limiting pull ring.

[0021] Preferably, the right-angle connector is also provided with a cover to cover the I-beam crossbeam and the I-beam longitudinal beam to form a cover for vehicle parking. The cover includes a tarpaulin covering the right-angle connector and the I-beam crossbeam, a fixing nut for fixing the tarpaulin and provided on the right-angle connector, and a sealing ring for sealing the connection between the tarpaulin and the fixing nut.

[0022] The top and bottom of the right-angle connector are provided with threaded openings for the fixing nut to be installed by threaded connection. The tarpaulin is provided with positioning openings for the fixing nut, and the positioning openings are reinforced with sealing. The sealing rubber rings are symmetrically arranged at both ends of the tarpaulin and are together fitted on the fixing nut.

[0023] Preferably, safety caps are movably fitted at both ends of the I-shaped longitudinal beam.

[0024] Preferably, the I-shaped crossbeam is provided with a first support plate at equal intervals for vehicle tires to roll over, and a second support plate is provided on the first support plate to distribute the pressure. The first support plate and the second support plate are distributed perpendicularly.

[0025] Preferably, modular devices with different functions are installed in the grooves of the I-beam crossbeam and the I-beam longitudinal beam via magnetic brackets, and locking knobs are screwed onto the magnetic brackets.

[0026] Preferably, the interior of the I-beam longitudinal beam is hollow, and the I-beam longitudinal beam, the I-beam cross beam, and the quick-connect plate are all equipped with reinforcing ribs;

[0027] Preferably, the I-beam longitudinal beams, I-beam cross beams, and quick-connect plates are all provided with wear-resistant coatings.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] I. The non-destructive installation part of this invention adopts a modular bulk design, which does not require welding, drilling or other destructive processing. Assembly can be completed by mechanical cooperation such as quick-connect plate buckles, scissor fork assembly hinges and limit pin insertions. It can be operated by a single person with simple tools. Compared with traditional concrete garages, it significantly shortens the construction cycle and improves assembly efficiency. Moreover, it can not only assemble single parking spaces but also adapt to the construction of multiple parking spaces.

[0030] Second, the core frame of this invention uses I-beam steel. The hollow design of the I-beam longitudinal beams not only ensures strength but also reduces weight. At the same time, the triple fixing and limiting structure of right-angle connecting seat, limiting pin and limiting pull ring greatly improves the strength of the steel structure and can withstand the vibration of vehicle starting and stopping and the load of long-term parking.

[0031] Third, the scissor lift assembly of the present invention is located at the beginning and end of the I-beam crossbeam, with a gap in the middle for the car door to open. It not only has a reasonable spatial layout, but also allows for adjustment of the garage height, thereby flexibly changing the applicability of the entire steel structure garage.

[0032] Fourth, the unique structural design of the I-beam crossbeam and I-beam longitudinal beam of this invention allows for the quick installation of modular equipment such as lighting, charging piles, monitoring, and parking guidance via magnetic brackets, without the need to modify the frame; the wiring harness can be hidden in the hollow part of the I-beam longitudinal beam to avoid exposure and aging, meeting diverse needs such as parking, charging and monitoring, and making it convenient to add or remove equipment in the future, adapting to different scenarios.

[0033] Fifth, the tarpaulin of the covering component of this invention can be flexibly retracted and extended, and its positioning opening is reinforced with sealing treatment to prevent rainwater leakage; it provides ample space for vehicle parking and personnel getting in and out of vehicles, and with the cross-distributed No. 1 and No. 2 support plates, vehicles are parked stably and personnel walk safely, solving the problems of bumps and leaks that are common in simple steel structure garages. Furthermore, the covering component is not limited to tarpaulins; a plate structure can also effectively achieve sealing and other effects. Attached Figure Description

Detailed Implementation

[0052] The following combination Figures 1-15 This application will be described in further detail.

[0053] This invention provides a modular prefabricated steel structure garage, which achieves zero-damage assembly, dynamic height adjustment, and functional expansion through an innovative beam interlocking structure and folding adjustment system, as detailed below:

[0054] Reference Figure 1As shown, this modular prefabricated steel structure garage uses I-beams as the core load-bearing frame, with an overall rectangular frame structure. It includes four rectangularly distributed I-beams 1 and four sets of I-beams 2 that match the I-beams 1. Connecting parts 3 are provided between the I-beams 1 and the I-beams 2. The parking area formed between two I-beams 1 of different heights among the four I-beams 1 is an important component for vehicle start and stop. This parking area is an important component for realizing the height adjustment and structural expansion and contraction of the garage.

[0055] The I-beams 1 are arranged in a rectangular pattern, forming the four horizontal sides of the garage frame. The number of I-beams 2 matches the number of I-beams 1, and the I-beams 2 connect to their corresponding I-beams 1 to form a complete rectangular frame. The I-beams 1 and I-beams 2 are fixed together by special connectors 3 to ensure the stability of the frame structure.

[0056] Reference Figure 2 As shown, within the stopping area of ​​the I-beam 1, there is also a spacing adjustment part 4 for adjusting the spacing between the two I-beams 1 in the height direction, and a non-destructive installation part 5 for quick connection between the scissor lift assembly 51 and the I-beam 1.

[0057] The non-destructive installation part 5 is the core component that enables the quick connection between the scissor lift assembly 51 and the I-beam 1, and the spacing adjustment part 4 is the core component used to adjust the height of the entire steel structure garage.

[0058] Reference Figure 3 , Figure 4 and Figure 5 As shown, the non-destructive installation part 5 mainly consists of three parts: a quick-connect plate 50, a scissor lift assembly 51, and a strip slider 52.

[0059] It includes quick-connect plates 50 that slide on both sides of the width direction of the I-shaped beam 1, scissor lift assemblies 51 distributed in an X shape, and several sets of strip sliders 52 that slide in the grooves of the I-shaped beam 1 respectively; the strip sliders 52 correspond to the four corners of the scissor lift assembly 51 respectively, and the strip sliders 52 are hinged to the four corners of the scissor lift assembly 51, and the strip sliders 52 are stepped; the strip sliders 52 not only slide in the grooves of the I-shaped beam 1, but also slide on the bottom of the quick-connect plates 50 that are fastened to the I-shaped beam 1, and the quick-connect plates 50 limit the position of the strip sliders 52.

[0060] It should be noted that the quick-connect plate 50 is relatively thick, and both its material and the I-beam 1 are made of steel, with a corrosion-resistant and rust-proof coating and a wear-resistant coating on the surface to ensure structural compatibility and durability between the two. The inner edge of the quick-connect plate 50 has an L-shaped hook, which can slide and engage with the edge of the I-beam 1.

[0061] Also refer to Figure 6 and Figure 7 As shown, the quick-connect plates 50 are slidably inserted into both sides of the I-beam 1 in the width direction, and the shape of the quick-connect plates 50 (refer to...) Figure 6 As shown, it slides on the I-beam 1 and can form a snap-fit ​​state with the I-beam 1. The matching slot structure at the edges of the two can prevent the quick-connect plate 50 from falling off, ensuring smooth sliding and providing sufficient clamping force when fixed.

[0062] The scissor lift assembly 51 is formed by two sets of cross-hinged rods, arranged in an X-shape. The two sets of rods have an arc-shaped structure that is wider in the middle and narrower at both ends. This design enhances the strength and support performance of the scissor lift assembly 51, effectively increasing its maximum withstand pressure. Furthermore, the scissor lift assembly 51 adjusts the garage height by moving the spacing between the sliding blocks 52.

[0063] It should be noted that the scissor lift assembly 51 of this application is provided in four sets, and these four sets of scissor lift assemblies 51 are distributed at both ends of the I-beam crossbeam 1, so that the middle is in an empty state, providing favorable space conditions for opening the car door and avoiding collision between the car door and the scissor lift assembly 51 when the car door is opened.

[0064] The strip slider 52 is slidably disposed in the groove of the I-beam 1 and corresponds to the four ends of the scissor lift assembly 51. After the quick-release plate 50 is installed, it can limit the sliding of the strip slider 52, further ensuring that the strip slider 52 can only move along the groove of the I-beam 1, thus improving its movement stability.

[0065] When assembling the I-beam 1, the specific steps are as follows: First, all the components of the steel structure garage are disassembled. After the vehicle transports them to the designated assembly position, place two I-beams 1 in the assembly area (these two I-beams 1 are connected to the foundation), and place the other two I-beams 1 to the side. It is important to pay attention to the spacing between the two I-beams 1 (to ensure parking space for vehicles and space for people to get in and out of the vehicle).

[0066] Then remove the protective film from the quick-connect plate 50, and slide the two quick-connect plates 50 to the I-beam 1 connected to the foundation, so that they overlap with the I-beam 1 (refer to...). Figure 5 As shown in the figure, quick-connect plates 50 are installed on both I-beams 1 placed in the assembly area.

[0067] Then, remove the protective film from the outside of the scissor lift assembly 51, and install the two sets of scissor lift assemblies 51 at the beginning and end of the I-beam 1 respectively. Finally, connect the other two I-beams 1 to the scissor lift assembly 51, so that the scissor lift assembly 51 is installed between two I-beams 1 located on the same vertical line among the four sets of I-beams 1. When installing the scissor lift assembly 51, the strip sliders 52 corresponding to its two corners are slidably installed in the grooves of the bottom I-beam 1, and the strip sliders 52 corresponding to the other two corners are slidably installed in the grooves of the top I-beam 1. At this time, the strip sliders 52 (stepped structure) are also restricted by the two quick-connect plates 50.

[0068] Since the entire installation process is achieved solely through the cooperation of mechanical structures, there is no need to perform any form of drilling, welding, or cutting on the I-beam 1, scissor lift assembly 51, or strip slider 52. This completely avoids damage to the component structure during the installation process, ensuring that all components can be repeatedly disassembled, reinstalled, and recycled, significantly improving the economy and environmental friendliness of the garage.

[0069] Reference Figure 8 and Figure 9 As shown, after the four sets of I-beam crossbeams 1 and scissor lift assembly 51 are installed, the I-beam crossbeams 1 need to be connected to each other using connector 3. Connector 3 is the core component for achieving a stable connection between the I-beam crossbeams 1 and the I-beam longitudinal beams 2. Its design focuses on ensuring the speed, stability, and non-destructive nature of the connection. It mainly consists of three parts: right-angle connecting seat 30, limiting pin 31, and limiting pull ring 32. Details are as follows:

[0070] The connector 3 includes several right-angle connectors 30 that are interference fit with the I-beam crossbeam 1 and the I-beam longitudinal beam 2, a limiting pin 31 that limits the position after assembling the right-angle connectors 30 with the I-beam crossbeam 1 and the I-beam longitudinal beam 2, and a limiting pull ring 32 that limits the position of the limiting pin 31.

[0071] The right-angle connector 30 has an installation groove 34 for the interference fit installation of the I-beam crossbeam 1 and the I-beam longitudinal beam 2. The right-angle connector 30, the I-beam crossbeam 1, and the I-beam longitudinal beam 2 are all provided with the same limiting holes 35 for the assembly of the limiting pin 31. The limiting pin 31 has anti-drop holes 36 at both ends for the assembly of the limiting pull ring 32.

[0072] The right-angle connector 30 is a right-angled block metal component, manufactured using an integral casting process, exhibiting excellent performance and capable of withstanding longitudinal and lateral loads generated when a vehicle is parked. On the two mutually perpendicular sides of the right-angle connector 30, mounting slots 34 are respectively provided for inserting the I-beam crossbeam 1 and the I-beam longitudinal beam 2. The cross-sectional shape and dimensions of the mounting slots 34 perfectly match the cross-sectional shape and dimensions of the I-beam crossbeam 1 and the longitudinal beam, achieving initial fixation of the components through an interference fit.

[0073] During specific implementation, after the I-beam 1 and the scissor assembly 51 are assembled, align the installation groove 34 on one side of the right-angle connecting seat 30 with the I-beam 1, and insert it into the head and tail ends of the I-beam 1 until the head and tail ends of all four I-beams 1 are completed with the installation of the right-angle connecting seat 30 (that is, eight right-angle connecting seats 30 correspond to four I-beams 1). Then, insert the I-shaped longitudinal beam 2 into the other installation groove 34 of the right-angle connecting seat 30, so that the I-shaped longitudinal beam 2 and the I-beam 1 are vertically distributed and form a frame with two "mouth" shapes.

[0074] It should be noted that when installing the right-angle connecting seat 30, the limiting holes 35 of the I-beam 1 and the I-shaped longitudinal beam 2 need to overlap with the limiting holes 35 opened on the right-angle connecting seat 30. Then, insert the limiting pin 31 into the limiting hole 35, and the limiting pin 31 is horizontally distributed. Further, the limiting pull ring 32 needs to be inserted into the anti-falling holes 36 at both ends of the limiting pin 31, so that the vibration generated when the vehicle enters and exits will not cause the limiting pin 31 to fall off.

[0075] Pass the limiting pull ring 32 through the anti-falling holes 36 at both ends of the limiting pin 31, and then bend and fix both ends of the limiting pull ring 32, which can prevent the limiting pin 31 from accidentally slipping out of the limiting hole 35, forming a triple-fixed structure of interference fit preliminary fixation, axial limitation of the limiting pin 31, and anti-detachment of the limiting pull ring 32, ensuring the long-term stability and reliability of the connection between the I-beam 1 and the I-shaped longitudinal beam 2.

[0076] Refer to Figure 9 and Figure 10 As shown, when the I-beam 1, the I-shaped longitudinal beam 2, the right-angle connecting seat 30, and the scissor assembly 51 are connected, the assembly of the main core components of the steel structure garage has been completed. At this time, the covering member 6 can be placed on the steel structure to achieve the purpose of wind and rain protection and privacy protection. Of course, if the steel structure garage is placed in a place with natural protection conditions such as an underground garage, the covering member 6 can not be installed, as follows:

[0077] The right-angle connecting seat 30 is also provided with a covering member 6 for covering the I-beam 1 and the I-shaped longitudinal beam 2 to form a place for the vehicle to park. The covering member 6 includes a tarpaulin 60 for covering the right-angle connecting seat 30 and the I-beam 1, a fixing nut 61 for fixing the tarpaulin 60 and provided on the right-angle connecting seat 30, and a sealing rubber ring 62 for sealing the connection between the tarpaulin 60 and the fixing nut 61.

[0078] The right-angle connector 30 has threaded openings 63 at both the top and bottom for the fixing nut 61 to be installed by threaded connection. The tarpaulin 60 has a positioning opening 64 for positioning the fixing nut 61, and the positioning opening 64 is reinforced with sealing. The sealing rubber rings are symmetrically arranged at both ends of the tarpaulin 60 and are together fitted on the fixing nut 61.

[0079] It should be noted that the covering component 6 mainly consists of three parts: tarpaulin 60, fixing nuts 61, and sealing rings 62. The tarpaulin 60 is made of a flexible material with high strength, high water resistance, and aging resistance. It can also be covered on the surface of the I-beam crossbeam 1 and I-beam longitudinal beam 2 with various plate-like structures. The installation principle is the same for both. This embodiment uses tarpaulin 60 as an example.

[0080] The tarpaulin 60 needs to completely cover the top and sides of the garage to form an enclosed parking space. In addition, the tarpaulin 60 is designed as an openable curtain structure, which can be opened and closed by zippers or Velcro, facilitating vehicle entry and exit.

[0081] The fixing nut 61 is a cylindrical metal component with external threads. It is made of stainless steel, which has good corrosion resistance and can prevent rust from forming during long-term outdoor use.

[0082] The sealing ring 62 is an annular elastic component, made of EPDM rubber or silicone rubber with good aging resistance and weather resistance. The inner diameter of the sealing ring 62 is matched with the outer diameter of the fixing nut 61, and the outer diameter is slightly larger than the diameter of the bottom gasket of the fixing nut 61, so as to ensure that it can completely cover the connection gap between the tarpaulin 60 and the right-angle connecting seat 30, forming a radial seal.

[0083] In practice, when the fixing nut 61 passes through the positioning port 64 of the tarpaulin 60 and is screwed into the threaded port 63 of the right-angle connector 30, the sealing ring 62 undergoes elastic deformation under the pressure of the fixing nut 61, tightly adhering to the surface of the tarpaulin 60 and the surface of the right-angle connector 30, completely sealing the connection gap, preventing rainwater from seeping into the garage from the gap, and ensuring the sealing and protection effect of the cover 6.

[0084] At the top and bottom of the right-angle connector 30, there are internal threaded openings 63 that are adapted to the fixing nut 61. The depth of the threaded opening 63 is adapted to the length of the fixing nut 61 to ensure that the fixing nut 61 can be fully screwed in.

[0085] A positioning opening 64 is provided on the tarpaulin 60 at the position corresponding to the threaded opening 63. The diameter of the positioning opening 64 is slightly smaller than the outer diameter of the fixing nut 61, ensuring that the fixing nut 61 can form a certain clamping force on the tarpaulin 60 when it passes through. At the same time, the edge of the positioning opening 64 is treated with multi-layer folding and sewing or heat sealing to enhance the tensile strength and waterproof performance of this part, and prevent the tarpaulin 60 from tearing due to the pressure of the fixing nut 61 or rainwater from seeping into the positioning opening 64.

[0086] To facilitate the taking down and storage of the tarpaulin 60, especially in seasons or scenarios when the tarpaulin 60 is not needed, a winding roller is installed on the tarpaulin 60. The winding roller is a cylindrical metal or engineering plastic component, fixedly installed along one edge of the tarpaulin 60, and its length is adapted to the width of the tarpaulin 60. Bearing brackets are set at both ends of the winding roller and fixed in the corresponding positions of the garage frame to ensure that the winding roller can rotate flexibly around its own axis. When the tarpaulin 60 needs to be taken down, the operator can manually rotate the winding roller or use an electric drive device (optional) to evenly wind the tarpaulin 60 onto the winding roller to achieve quick taking down and taking down, reduce the space occupied by the tarpaulin 60, and at the same time avoid the tarpaulin 60 from aging or being damaged due to long-term unfolding.

[0087] Safety caps 65 are movably fitted at both ends of the I-beam longitudinal beam 2. The purpose is to prevent the hard edges of the I-beam longitudinal beam 2 from directly rubbing against the tarpaulin 60, which could cause tears in the tarpaulin 60.

[0088] After the tarpaulin 60 is installed on the I-beam crossbeam 1 and I-beam longitudinal beam 2 that form the frame, the scissor lift assembly 51 is moved to adjust the height of the uppermost I-beam crossbeam 1 and I-beam longitudinal beam 2, thereby adjusting the height of the entire vehicle parking area to facilitate parking for different vehicles. See below for details:

[0089] Reference Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown, the spacing adjustment part 4 includes a movable groove 40 opened at one end of the quick-connect plate 50 near the strip slider 52, two sets of adjusting gears 41 symmetrically arranged on the strip slider 52, a limiting rod 42 for limiting the adjusting gears 41, and a limiting rack 43 that meshes with the adjusting gears 41 and is disposed in the movable groove 40 of the quick-connect plate 50 on one side.

[0090] The strip slider 52 has a working groove 44 for the adjustment gear 41 to rotate. The adjustment gear 41 in the strip slider 52 is movably engaged with the limiting rack 43 in the quick-connect plate 50. The limiting rod 42 is slidably inserted into the strip slider 52, and one end of the limiting rod 42 extends towards the limiting rack 43. Several insertion interfaces 45 for the limiting rod 42 to be inserted are equally spaced on the limiting rack 43.

[0091] The strip slider 52 has a countersunk hole 520 for the insertion of the limiting rod 42. The countersunk hole 520 of the strip slider 52 has two sets of symmetrical snap-fit ​​springs 521. The top of the limiting rod 42 has a snap-fit ​​interface 522 corresponding to the snap-fit ​​springs 521.

[0092] The spacing adjustment part 4 is mainly composed of four components: movable groove 40, adjusting gear 41, limiting rod 42, and limiting rack 43. It completes the operation through gear and rack meshing transmission and insertion limiting.

[0093] In practice, the movable slot 40 is opened on the quick-connect plate 50 to provide movement space for the adjusting gear 41 and the limiting rod 42. The adjusting gear 41 consists of two sets of symmetrical alloy components installed in the strip slider 52. When rotated, it can drive the meshing limiting rack 43 to move, thereby pushing the crossbeam to adjust its height. The limiting rack 43 is fixed in the movable slot 40 and changes the crossbeam spacing with the movement of the adjusting gear 41. After the height is adjusted, the limiting rod 42 is inserted into the interface of the limiting rack 43 to restrict the rotation of the gear and fix the position of the crossbeam. The interfaces of the limiting rack 43 are evenly distributed, supporting multiple height adjustments.

[0094] When the garage height needs to be adjusted, the operator first fixes two strip sliders 52 on one side of the scissor lift assembly 51, then manually controls the other two strip sliders 52 to move along the groove of the I-beam 1 to the designated position, and then fixes all the strip sliders 52 to the I-beam 1.

[0095] When the moving strip slider 52 is in motion, the adjusting gear 41 engages with the limiting rack 43 on one side of the quick-connect plate 50 (the limiting rack 43 is not provided in the movable groove 40 of the other side of the connecting plate) and is in a passive rotation state.

[0096] After the strip slider 52 moves to the designated position, the limiting rod 42 is inserted along the countersunk hole 520 on the strip slider 52, so that one end of the limiting rod 42 passes through the strip slider 52 and is inserted into the insertion interface 45 on the limiting rack 43. At this time, the limiting rack 43 is fixed and cannot move further, thereby restricting the rotation of the adjusting gear 41. If the strip slider 52 is pushed further, the adjusting gear 41 cannot rotate because it is fixed, and at the same time, the adjusting gear 41 is engaged with the limiting rack 43, so it cannot move, thereby fixing the angle of the scissor lift assembly 51 and further fixing the position of the I-beam 1.

[0097] The interfaces on the limiting rack 43 are opened at even intervals to ensure that the garage height can be adjusted in multiple positions to meet the parking needs of different types of vehicles.

[0098] Reference Figure 14 As shown, in order to further improve the stability of the limit rod 42 during use and prevent it from accidentally falling off due to external forces such as vibration and collision, which would cause the garage height to become out of control, this technical solution optimizes the limiting structure of the strip slider 52. It mainly forms a double limiting cooperation by adding a snap-fit ​​spring piece 521 to the strip slider 52 and a snap-fit ​​interface 522 on the limit rod 42.

[0099] A countersunk hole 520 is formed on the surface of the strip slider 52. Its diameter is slightly larger than the diameter of the limiting rod 42, and its depth is adapted to the height of the protruding structure at the top of the limiting rod 42. The purpose of the countersunk hole 520 is to ensure that the top of the limiting rod 42 is flush with the surface of the strip slider 52 after insertion, avoiding the safety hazard caused by the top of the limiting rod 42 protruding, and preventing foreign objects from entering the hole and affecting the insertion and removal operation of the limiting rod 42.

[0100] The snap-fit ​​spring piece 521 is an elastic metal component made of spring steel, possessing excellent elastic deformation capability and fatigue life, maintaining stable elastic performance even after multiple insertion and removal operations. When the limiting rod 42 is inserted into the countersunk hole 520 of the strip slider 52 and reaches the designated position, the snap-fit ​​spring piece 521, under the action of elastic force, snaps into the snap-fit ​​interface 522 of the limiting rod 42, forming an additional mechanical limit. This limiting structure not only restricts the movement of the crossbeam through the insertion and engagement of the limiting rod 42 and the limiting rack 43, but also prevents the limiting rod 42 from accidentally falling off through the elastic engagement of the snap-fit ​​spring piece 521 and the snap-fit ​​interface 522.

[0101] Looking back Figure 2 As shown, the I-beam 1 is provided with a first support plate 10 at equal intervals for vehicle tires to roll over, and a second support plate 11 is provided on the longitudinal plate to distribute the pressure of the support plate. The first support plate 10 and the second support plate 11 are distributed perpendicularly.

[0102] After the garage is fully assembled and covered with tarpaulin 60, some internal assembly remains. When a car is parked in the parking area, in order to ensure the airtightness of the entire garage, a first support plate 10 and a second support plate 11 are installed on the I-beam 1 connected to the foundation.

[0103] The first support plate 10 is fixed to the upper surface of the I-beam 1 at even intervals. Its length direction is consistent with the length direction of the I-beam 1, and its width is determined according to the width of the vehicle tires. This ensures that when the vehicle is parked, the tires can completely press on the first support plate 10, avoiding direct contact between the tires and the flanges of the I-beam 1, and preventing excessive local stress on the flanges and deformation. The connection method between the first support plate 10 and the I-beam 1 can be welding or binding, depending on actual needs. Welding provides higher connection strength and is suitable for long-term fixed use; binding provides detachability, facilitating later maintenance or replacement.

[0104] Reference Figure 8 As shown, modular devices with different functions are installed in the grooves of the I-beam 1 and the I-beam 2 via magnetic brackets 20, and locking knobs 21 are screwed onto the magnetic brackets 20.

[0105] To meet the diverse and intelligent needs of modern users for parking facilities, this technical solution features a specially designed functional expansion structure on the garage frame, which enables the rapid installation and disassembly of different modular devices through magnetic brackets 20.

[0106] The magnetic bracket 20 is a metal bracket structure with strong magnetic adsorption capability. One end is equipped with a locking knob 21 to connect with the garage frame, and the other end uses magnetic attraction to attach the metal shell to fix the equipment. It can be used to install lighting equipment, electric vehicle charging piles, video surveillance cameras, environmental monitoring sensors (such as temperature and humidity sensors, carbon monoxide sensors), parking space guidance indicators, and parking space license plate information, etc.

[0107] Once the magnetic bracket 20 is attached to the designated position on the I-beam 1 or I-beam 2, the operator rotates the locking knob 21 to make the rubber pad on the magnetic bracket 20 fit tightly against the steel surface, generating a certain friction force. This friction, combined with the magnetic force, ensures the stability of the bracket and prevents displacement or detachment.

[0108] The magnetic bracket 20 allows for quick installation in different locations within the garage without requiring any drilling or welding of the garage frame, achieving completely non-destructive functional expansion.

[0109] In addition, the interior of the I-beam longitudinal beam 2 is hollow, which ensures strength while reducing its weight. At the same time, the grooves and hollow structure of the I-beam longitudinal beam 2 can also allow for the concealed installation of the wire harness, avoiding the exposure of the wire harness.

[0110] Example 2: Based on Example 1, in order to further ensure the stability of the garage installation, this application also proposes mounting nails 70. If the garage is installed outdoors, the entire steel structure garage is directly installed on the ground, which may cause displacement due to long-term starting and stopping of vehicles. Therefore, this application proposes mounting nails 70. When installing outdoors, it is necessary to first clear the gravel, weeds and debris in the installation site, confirm the flatness of the ground, and at the same time carry out the foundation pouring and construction, and fix the mounting nails 70 on the foundation to ensure the overall stability of the entire steel structure garage.

[0111] If it is installed indoors, the indoor floor is generally a concrete floor. The mounting nails 70 are directly nailed to the ground at a safe position on the ground, which can also ensure the overall stability of the entire steel structure garage.

[0112] The mounting nail 70 has a T-shaped structure, consisting of a cylindrical structure and a plate-like structure. The top of the mounting nail 70 slides within the groove of the I-beam 1, similar in structure to the strip slider 52, ensuring that the mounting nail 70 can connect to the I-beam 1. After determining the position of the mounting nail 70, connecting it to the foundation can greatly improve the stability of the entire garage.

[0113] Example 3: Example 1 of this application only describes the assembly of a single garage. If multiple garages need to be installed in a row indoors, no additional parts are required. The installation method of the right-angle connector 30 can be changed directly.

[0114] Reference Figure 15 As shown, the right-angle connector 30 in this embodiment has two mounting slots 34. The mounting slot 34 connected to the I-beam 2 is a through slot, while the mounting slot 34 connected to the I-beam 1 is a non-through slot. When multiple garages need to be installed in a row, the I-beams 2 of adjacent steel structure garages are installed in the through mounting slot 34 of the same right-angle connector 30, so that the I-beams 2 of the two steel structure garages can share one right-angle connector 30. This can save multiple right-angle connectors 30, and will not affect the stability of multiple steel structure garages. At the same time, multiple steel structure garages are assembled using common components, which greatly improves stability.

[0115] During work:

[0116] The first step is to designate the installation site, clear away debris, and confirm the flatness of the ground. For outdoor installation, a foundation must be poured first and T-shaped mounting nails 70 fixed in place. For indoor installation, the mounting nails 70 can be fixed directly in a safe area on the concrete ground.

[0117] Step 2: Install the I-beam 1 onto the mounting nail 70, then slide the quick-connect plate 50 to both sides of the I-beam 1 (forming a snap-fit ​​state to prevent it from falling off), then slide the strip slider 52 at the end of the scissor lift assembly 51 into the groove of the I-beam 1 and limit it through the quick-connect plate 50; then connect the other two I-beams 1 to the scissor lift assembly 51, so that the scissor lift assembly 51 is installed between the beams on the same vertical line.

[0118] Step 3: Install right-angle connectors 30 at the beginning and end of the four crossbeams. Insert the I-beam longitudinal beam 2 into another mounting slot 34 of the right-angle connector 30, ensuring that the limiting holes 35 of the I-beam longitudinal beam 2 and the I-beam crossbeam 1 are aligned and overlapped with the limiting holes 35 of the corresponding right-angle connectors 30. Pass the limiting pin 31 through the limiting holes 35 of the three beams, and then insert the limiting pull ring 32 into the anti-drop hole 36 of the limiting pin 31 and bend it to fix it, forming a triple fixation.

[0119] Step 4: Cover the top and sides of the frame (composed of I-beam longitudinal beams 2, I-beam crossbeams 1, and right-angle connecting seats 30) with the tarpaulin 60, align the positioning port 64 of the tarpaulin 60 with the threaded port 63 of the connecting seat, insert the fixing nut 61 and tighten it, and put the sealing rubber rings 62 on both ends of the tarpaulin 60 (elastic deformation to seal the gaps); install the winding roller (with bearing bracket) on the edge of the tarpaulin 60 for easy loading and unloading.

[0120] Safety caps 65 are fitted at both ends of the I-beam longitudinal beam 2 to prevent the hard edges of the longitudinal beam from rubbing against and damaging the tarpaulin 60.

[0121] Step 5: Fix one side of the scissor lift assembly 51 with a strip slider 52, control the movement of the other side of the strip slider 52, and adjust the height of the top crossbeam in real time. After the height is in place, insert the limiting rod 42 into the countersunk hole 520 of the strip slider 52 until it passes through the insertion interface 45 of the limiting rack 43; the spring clip 521 in the countersunk hole 520 is inserted into the locking interface 522 of the limiting rod 42 to form a double limiting.

[0122] Step 6: Fix the No. 1 support plate 10 (for tire rolling) at intervals on the I-shaped crossbeam 1 near the foundation, and then install the No. 2 support plate 11 vertically (to distribute the pressure of the plate) to avoid local deformation of the crossbeam flange due to stress.

[0123] Step 7: Utilize the grooves and hollow structure of the I-beam 2 to install the modular equipment via the magnetic bracket 20.

[0124] Step 8: Confirm that all connectors 3 are secure, the scissor lift assembly 51 is flexible and retractable, and the tarpaulin 60 is sealed without leakage. The garage assembly is now complete.

[0125] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
