Description

Technical Field

[0001] This utility model relates to the field of steel bar processing shed technology, and more specifically, to a steel bar processing shed with a retractable flexible roof. Background Technology

[0002] In related technologies, traditional steel bar processing sheds mostly use fixed rigid roofs, which have the following problems: 1. Poor spatial flexibility: It cannot adapt to the processing needs of steel bars at different heights. For example, when hoisting large steel bars, the ceiling needs to be temporarily removed, increasing safety risks and construction costs. Their size and dimensions are usually fixed, making it difficult to flexibly adjust the working space according to the needs of different construction stages. For instance, when hoisting large steel bars, the fixed ceiling restricts the hoisting path, resulting in the steel bars needing to be transferred multiple times, which not only wastes manpower and resources but also reduces construction efficiency.

[0003] 2. Complex installation and disassembly: The integral structure results in large transportation volume, time-consuming on-site assembly, the need for large hoisting equipment, and difficulty in quickly responding to site layout adjustments.

[0004] 3. Structural safety issues: Common processing sheds use rigid roofs, which are prone to damage due to excessive loads when facing extreme weather conditions such as strong winds and snow accumulation, posing significant safety hazards.

[0005] 4. Material and Construction Issues: Most traditional processing sheds are constructed on-site using steel pipes. The construction and dismantling process is complex, requires professional personnel, and the cutting of steel pipes leads to resource waste and high costs. Furthermore, this method fails to meet the requirements for standardized and regulated safety management.

[0029] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0030] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0031] Please see Figure 1 and Figure 2 This utility model provides a rebar processing shed 10 with a retractable flexible roof. The rebar processing shed 10 includes a support frame 100, a track 200, a retractable flexible roof 300, and a drive device 400. The support frame 100 is fixed to the rebar processing area 12. The track 200 is located on top of the support frame 100. The retractable flexible roof 300 includes a telescopic frame 310, a flexible tarpaulin 320, and pulleys 330. The pulleys 330 are installed at the bottom of the telescopic frame 310 and can move linearly along the track 200. The flexible tarpaulin 320 is laid on top of the telescopic frame 310. The drive device 400 is located on the track 200 and can move linearly along the track 200. The drive device 400 is connected to the telescopic frame 310 and is used to drive the telescopic frame 310 to extend and retract, and to cause the flexible tarpaulin 320 to fold or unfold.

[0032] The rebar processing shed 10 with a retractable flexible roof is driven by a drive device 400 to extend and retract a telescopic frame 310. During extension and retraction, the telescopic frame 310 moves linearly along a track 200, causing the flexible tarpaulin 320 to fold or unfold. When large rebar hoisting is required, the drive device 400 can retract the telescopic frame 310, causing the flexible tarpaulin 320 to fold, expanding the working space and facilitating the hoisting and processing of large rebars. When large rebar hoisting is not required, the drive device 400 can extend the telescopic frame 310, causing the flexible tarpaulin 320 to unfold, reducing the working space to meet operational needs. Therefore, this rebar processing shed can flexibly adjust the working space and coverage area to adapt to the processing needs of rebars of different heights (such as hoisting by large cranes), avoiding the problem of temporary dismantling of traditional fixed roofs, reducing safety risks and modification costs. The retractable flexible roof 300 can be extended or retracted at any time according to construction needs, expanding or shrinking the working space, facilitating the hoisting and processing of large rebars, and improving construction efficiency.

[0033] In addition, this steel bar processing shed can also achieve the following technical effects: Optimized construction efficiency and mobility: It enables modular production and transportation, and the flexible tarpaulin can be folded 320°, reducing the transportation volume and effectively reducing transportation costs. Enhanced safety: The retractable flexible canopy 300 effectively buffers loads such as strong winds and snow accumulation, reducing the risk of damage to the steel processing shed due to extreme weather and ensuring the safety of construction personnel and equipment.

[0034] Easy to assemble and disassemble: The support frame 100 can be modularly designed, which is convenient for quick assembly and disassembly; the retractable flexible canopy 300 is also easy to install and disassemble, reducing construction difficulty and cost.

[0035] It should be noted that the support frame 100 and the retractable flexible canopy 300 can adopt a modular structure design, which facilitates quick assembly and disassembly, and also facilitates modular transportation, reducing transportation costs. In addition, in this embodiment of the utility model, there are two of each of the support frame 100, track 200, telescopic frame 310, pulley 330 and drive device 400, respectively located on the left and right sides. For the support frame 100, track 200, telescopic frame 310, pulley 330 and drive device 400 on the same side, their installation structure is as described above. It is worth noting that the flexible tarpaulin 320 is laid on top of the telescopic frames 310 on both sides. Except for the flexible tarpaulin 320, the specific structures mentioned below can be considered as descriptions of the support frame 100, track 200, telescopic frame 310, pulley 330 and drive device 400 on the same side. In addition, the material of the flexible tarpaulin 320 can be plastic-coated fiberglass cloth (weight ≥800g / ㎡), with a PVDF coating on the surface, weather resistance of more than 10 years, and tensile strength ≥25kN / m.

[0036] Additionally, it should be noted that the pulley 330 is installed at the bottom of the telescopic frame 310 and can move linearly along the track 200. Specifically, the connection method can be: the pulley 330 and the track 200 can be in sliding or rolling fit, as long as the pulley 330 can move linearly along the track 200.

[0037] Furthermore, the support frame 100 includes multiple base plates 110, multiple support columns 120, and multiple diagonal support rods 130. Each base plate 110 is fixed to the rebar processing area 12 by pre-embedded bolts 140. The bottom of each support column 120 is connected to the base plate 110, and the top of each support column 120 is connected to the track 200. Two diagonal support rods 130 are connected between each adjacent support column 120, and the two diagonal support rods 130 are X-shaped.

[0038] It should be noted that a flat, hardened surface is laid on the construction site as the rebar processing area 12. The rebar processing area 12 can be made of C25 concrete (thickness ≥ 20cm), with a flatness error ≤ 3mm / m. Additionally, the base plate 110 can be a 30cm × 30cm × 1cm steel plate. The location of the rebar processing shed is determined according to the construction site plan, and tools such as a level are used to ensure the flatness of the ground. If the ground is uneven, the pre-embedded bolts 140 can be adjusted to make the support frame 100 level. Furthermore, by setting up support pillars 120, and with two diagonal support pillars 130 arranged in an X-shape between each adjacent support pillar 120, the overall structural stability of the support frame 100 is improved, enhancing the support effect of the support frame 100 on the structure above it.

[0039] Optionally, the support pole 120 can be made of No. 14 I-beam, which is straight and 220cm long, and its bottom can be bolted to the base plate 110. The spacing between two adjacent support poles 120 can be set to 300cm. The diagonal support poles 130 can be made of 4cm×8cm square steel tubes, and two diagonal support poles 130 intersect each other to form an X shape. The bottom of the two diagonal support poles 130 can be bolted to the bottom of the base plate 110 or the support pole 120, and the top of the two diagonal support poles 130 can be bolted to the top of the track 200 or the support pole 120.

[0040] In addition, the track 200 can be made of No. 20 I-beams. The track 200 is laid on the top or side of multiple support poles 120 and can be bolted to the top of the multiple support poles 120, which facilitates the installation and disassembly of the track 200. The track 200 is equipped with guide grooves or rollers, which cooperate with the pulleys 330 to ensure linear movement during extension and retraction, preventing deviation or jamming.

[0041] Furthermore, the telescopic frame 310 includes multiple uprights 311 and multiple telescopic rod assemblies 312. Each upright 311 has a pulley 330 at its bottom, and at least one integral X-shaped telescopic rod assembly 312 is provided between any two adjacent uprights 311. One of the uprights 311 at one end is connected to the drive device 400. Each telescopic rod assembly 312 includes two rods 313, which are hinged together at their middle portions. The lower ends of the two rods 313 are respectively hinged to the lower ends of two adjacent uprights 311, and the upper ends of the two rods 313 are respectively slidably engaged with the upper ends of two adjacent uprights 311.

[0042] By setting up multiple uprights 311 and multiple telescopic rod assemblies 312, when the drive device 400 drives the upright 311 located at one end, the upright 311 drives the pulleys 330 installed on it, causing the pulleys 330 at the bottom of the multiple uprights 311 to move linearly along the track 200. As the multiple uprights 311 move linearly along the track 200 via the pulleys 330, the flexible tarpaulin 320 on top gradually folds or unfolds. Furthermore, since the upper ends of two rods 313 slide against the upper ends of two adjacent uprights 311, when the uprights 311 move, the upper ends of the two rods 313 rise or fall along the uprights 311, thereby causing the X-shaped telescopic rod assembly 312 to fold or unfold. This allows for good telescopic extension and retraction of the telescopic frame 310, making the entire telescopic movement smoother.

[0043] It should be noted that in this embodiment, the upright 311 can be a round steel pipe with a diameter of 8cm, and the pole 313 can be a square steel pipe of 4cm×8cm.

[0044] Please see Figure 3 Optionally, to facilitate smoother upward or downward movement of the upper ends of the two rods 313 along the upright 311 during its movement, in this embodiment of the invention, each rod 313 is provided with an interconnected slip ring 314 and a locking pin 315 at its upper end. The locking pin 315 is hinged to the upper end of the rod 313, and the slip ring 314 is fitted onto the upper end of the upright 311 and can slide along the slip ring 314.

[0045] Please see Figure 4Furthermore, the retractable flexible canopy 300 also includes an anti-detachment guide structure 340 disposed at the bottom of the upright 311. The anti-detachment guide structure 340 includes a first connecting plate 341, two second connecting plates 342, and two anti-detachment components 343. The top side of the first connecting plate 341 is connected to the bottom of the upright 311, the tops of the two second connecting plates 342 are connected to the bottom side of the first connecting plate 341, and both ends of the pulley 330 are connected to the two second connecting plates 342 respectively. The two anti-detachment components 343 are respectively inserted through the bottom of the two second connecting plates 342, forming a symmetrical L-shaped structure with the second connecting plates 342. The two symmetrically arranged L-shaped structures cover the top of the pulley 330 and the track 200.

[0046] By setting up an anti-detachment guide structure 340, and forming two L-shaped structures by connecting the anti-detachment component 343 with the second connecting plate 342, the two structures respectively cover the top of the pulley 330 and the track 200. On the one hand, the track 200 and the pulley 330 can play a limiting role to prevent the pulley 330 and the track 200 from separating. On the other hand, the pulley 330 can further play a guiding role to ensure that it moves in a straight line along the track 200, making the operation of the pulley 330 on the track 200 smoother.

[0047] In this embodiment, the anti-detachment component 343 can be made of bolts. Additionally, both ends of the pulley 330's shaft can be bolted to two second connecting plates 342 respectively. The first connecting plate 341 is made of 8cm × 8cm steel plate with a thickness of 1cm, and is welded to the bottom of the upright 311.

[0048] In an optional embodiment of this utility model, the track 200 includes a support rail 210 with an I-shaped cross-section and a sliding part 220 connected to the top of the support rail 210. The pulley 330 is movably engaged with the sliding part 220. The top plate of the support rail 210 and the sliding part 220 are located between two second connecting plates 342, and two anti-detachment members 343 are respectively located on the lower side of opposite ends of the top plate.

[0049] It should be noted that the support rail 210 can be made of No. 20 I-beams and laid on top of multiple support poles 120. The support rail 210 is I-shaped, and its top can be considered as a top plate. The pulley 330 and the sliding part 220 can be in a sliding fit or a rolling fit. Two anti-detachment components 343 are located on the lower side of opposite ends of the top plate. Thus, the two anti-detachment components 343 and the two second connecting plates 342 form an L-shaped structure. It can be considered that the anti-detachment components 343 and the second connecting plates 342 form a locking effect on the top of the support rail 210, thereby improving the anti-detachment and guiding effect on the pulley 330 and the rail 200.

[0050] Please see Figure 5In another optional embodiment of this utility model, the anti-detachment guide structure 340 further includes a guide wheel 344, and the cross-section of the track 200 is I-shaped. The pulley 330 is movably engaged with the top plate of the track 200, and two anti-detachment components 343 are respectively located on the lower side of opposite ends of the top plate. The guide wheel 344 is provided at the end of each of the two anti-detachment components 343 away from the second connecting plate 342.

[0051] The guide wheel 344 can abut against the lower side of the top of the track 200 or leave a certain gap, which can effectively guide the movement between the pulley 330 and the track 200, thereby ensuring that the pulley 330 moves more smoothly on the track 200.

[0052] Please continue reading. Figure 1 Furthermore, the retractable flexible canopy 300 may also include a fixing frame 350. The fixing frame 350 includes a fixed upright 351 and a support rod 352. The upright 311 and the fixed upright 351 at the end of the telescopic frame 310 away from the drive device 400 are respectively connected to the two ends of the support rod 352. The bottom of the fixed upright 351 is fixedly connected to the track 200.

[0053] By setting the fixed frame 350, the end of the telescopic frame 310 that is away from the drive device 400 can be fixedly connected to the fixed pole 351, so that the drive device 400 can ensure that the end away from the drive device 400 is fixed when driving the telescopic frame 310 to extend or retract, so that the telescopic frame 310 can extend or retract more smoothly.

[0054] In addition, the retractable flexible canopy 300 may also include a drive pole 360. The drive device 400 is connected between the pole 311 near the drive device 400 end of the telescopic frame 310 and the drive pole 360. The bottom of the drive pole 360 ​​is also provided with a pulley 330 that can move linearly along the track 200.

[0055] By setting the drive pole 360, the drive device 400 can be fixed between the pole 311 near the end of the drive device 400 and the drive pole 360, thus ensuring the driving effect of the drive device 400 on the telescopic frame 310.

[0056] Please see Figure 6Additionally, the drive unit 400 may include a drive body 410, an engine 420, a transmission gear 430, and a moving wheel 440. The two ends of the drive body 410 are connected to the upright 311 and the drive upright 360, respectively. The engine 420 is mounted on the drive body 410 and is connected to the transmission gear 430. The shaft of the moving wheel 440 is connected to the transmission gear 430, and the moving wheel 440 is mounted on the track 200 and can move linearly along the track 200. In this embodiment, the moving wheel 440 has a similar structure to the pulley 330.

[0057] In this way, the engine 420 can transmit power through the transmission gear 430 and drive the moving wheel 440 to move linearly along the track 200. During this process, the drive body 410 drives the upright 311 to move, causing the pulley 330 on the upright 311 to also move linearly along the track 200, thereby realizing the extension and retraction of the telescopic frame 310. Optionally, in this embodiment, in order to improve the driving effect of the drive device 400, the engine 420, transmission gear 430 and moving wheel 440 can be set as two sets, respectively set at both ends of the drive body 410 in the length direction.

[0058] Please see Figure 2 Additionally, the retractable flexible canopy 300 may also include a support truss 370. Two telescopic frames 310, two support frames 100, two drive units 400, and two tracks 200 are each provided. A support truss 370 is provided between the tops of the corresponding uprights 311 of the two telescopic frames 310.

[0059] It should be noted that in this embodiment, support trusses 370 are also connected to the fixed uprights 351 and the driving uprights 360. Flexible tarpaulin 320 is sequentially laid on multiple support trusses 370. By setting up the support trusses 370, good support can be provided for the uprights 311, fixed uprights 351, driving uprights 360, and flexible tarpaulin 320. The support trusses 370 are 30cm high, 4cm × 8cm square steel tube trusses to improve the support effect.

[0060] Additionally, it should be noted that in optional embodiments of this utility model, hydraulic adjustment devices can be added to the upright 311, fixed upright 351, and driving upright 360. These hydraulic adjustment devices allow for height adjustment, facilitating the adjustment to the designed height. Alternatively, fixed swivel casters with brakes can also be configured.

[0061] In summary, the rebar processing shed 10 with a retractable flexible canopy is driven by a drive device 400 to extend and retract the telescopic frame 310. During extension and retraction, the telescopic frame 310 moves linearly along the track 200, causing the flexible tarpaulin 320 to fold or unfold. When large rebars need to be hoisted, the drive device 400 can retract the telescopic frame 310, causing the flexible tarpaulin 320 to fold, thus expanding the working space and facilitating the hoisting and processing of large rebars. When large rebar hoisting is not required, the drive device 400 can extend the telescopic frame 310, causing the flexible tarpaulin 320 to unfold, thus reducing the working space and meeting operational needs.

[0062] In addition, the following describes a construction method for a rebar processing shed 10 with a retractable flexible roof, provided by an embodiment of this utility model, used to construct the rebar processing shed described above. Technical details not mentioned herein can be found in the structural description of the rebar processing shed. The construction method includes the following steps: Step S101: In the factory, modules such as uprights 311, supporting uprights 120, fixed uprights 351, driving uprights 360, crossbeams of supporting trusses 370, flexible tarpaulin 320, and driving device 400 are manufactured according to design standards. Among them, the flexible tarpaulin 320 adopts a hot-press molding process to ensure sealing, and the driving device 400 completes pre-assembly and debugging.

[0063] In step S102, the disassembled modules are transported in standard containers. The uprights 311, support uprights 120, fixed uprights 351, drive uprights 360 and crossbeams are nested and packaged. The flexible tarpaulin 320 is folded and put into a waterproof bag, which reduces transportation costs by 40%.

[0064] Step S103: Lay a flat and hardened steel bar processing area 12 at the construction site. Optionally, a flat and hardened ground is laid at the construction site as the steel bar processing area 12. The steel bar processing area 12 can be made of C25 concrete hardened ground (thickness ≥20cm) with a flatness error ≤3mm / m.

[0065] In step S104, pre-embedded bolts 140 are installed on the steel bar processing site 12, and multiple base plates 110 are fixed to the steel bar processing site 12 by the pre-embedded bolts 140. The bottoms of multiple support poles 120 are connected to the base plates 110, and two diagonal support poles 130 are connected between two adjacent support poles 120. The two diagonal support poles 130 are X-shaped, thereby forming a support frame 100.

[0066] According to the construction site plan, the location of the steel bar processing shed was determined, and tools such as a level were used to ensure the flatness of the ground. If the ground was uneven, the pre-embedded bolts 140 were adjusted to make the support frame 100 level. According to the design plan, the components of the support frame 100 were assembled on site and fastened with bolts to form a stable frame structure.

[0067] Step S105: Install the rail 200 on the top of the support pole 120, and ensure that the rail 200 is installed firmly and that its straightness meets the requirements.

[0068] The track 200 can be made of No. 20 I-beams. The track 200 is laid on the top or side of multiple support poles 120 and can be bolted to the top of the multiple support poles 120 respectively, which facilitates the installation and disassembly of the track 200.

[0069] Step S106: The retractable flexible canopy 300 is pre-assembled on the ground.

[0070] The retractable flexible canopy 300 includes a telescopic frame 310, a flexible tarpaulin 320, pulleys 330, a fixed frame 350, a drive pole 360, and a support truss 370. The telescopic frame 310 includes multiple poles 311 and multiple telescopic rod groups 312. The pulleys 330 are installed at the bottom of the poles 311, and at least one integral X-shaped telescopic rod group 312 is provided between any two adjacent poles 311. The poles 311 at one end of the telescopic frame 310 and the fixed poles 351 of the fixed frame 350 are respectively connected to the two ends of the support rods 352. The drive device 400 is connected between the poles 311 and the drive poles 360 at the end of the telescopic frame 310 closest to the drive device 400. The support truss 370 is installed between the tops of the corresponding poles 311 of the two telescopic frames 310. The flexible tarpaulin 320 is laid on top of the telescopic frame 310 and the support truss 370 by hoisting.

[0071] The uprights 311 can be adjusted to their designed height via a hydraulic adjustment device, and the casters are braked. After the support truss 370 is deployed, it is connected to the uprights 311 using high-strength bolts, and the verticality of the overall frame is checked. The flexible tarpaulin 320 is hoisted, and the traction rope is connected to the drive unit 400, and its drive function is tested until it is smooth. Lighting, ventilation, and other functional modules can also be installed, connected to the main power supply, and the linkage control tested.

[0072] In step S107, the retractable flexible canopy 300 is installed onto the track 200 on the support frame 100 using a crane or manual labor. Specifically, pulleys 330 are fitted onto the track 200 to securely connect the bottom of the fixed upright 351 to the track 200. The retractable flexible canopy 300 also includes an anti-detachment guide structure 340 located at the bottom of the upright 311. The anti-detachment guide structure 340 is installed at the bottom of the upright 311. The anti-detachment guide structure 340 has two symmetrical L-shaped structures that cover the top of the pulleys 330 and the track 200.

[0073] The track 200 is installed on the top or side of the support frame 100 and is made of high-strength steel. The track 200 is equipped with guide grooves or rollers, which cooperate with the pulleys 330 on the retractable flexible roof 300 to ensure that the retractable flexible roof 300 maintains linear movement during the extension and retraction process and prevents deviation or jamming.

[0074] In step S108, the drive device 400 is placed on the track 200 and can move linearly along the track 200. The drive device 400 is connected to the telescopic frame 310 to drive the telescopic frame 310 to extend and retract, and to drive the flexible tarpaulin 320 to fold or unfold.

[0075] Step S109: Perform a movement test on the drive device 400.

[0076] This includes starting the self-drive control system, testing its straight-line walking and obstacle avoidance functions, connecting the pipelines and lines of the electrical control system or hydraulic control system, and debugging to ensure that the drive unit 400 is operating normally.

[0077] Step S110: Test the flexible tarpaulin 320.

[0078] The tests include simulating heavy rain conditions to assess waterproofing performance and impact resistance (such as steel ball drop tests). The flexible tarpaulin 320 material can be made of coated fiberglass cloth (weight ≥ 800g / ㎡), with a PVDF coating, providing weather resistance for over 10 years and a tensile strength ≥ 25kN / m.

[0079] Step S111: Conduct a security test.

[0080] Trigger the overload protection device to verify the shutdown and alarm functions. The overload protection device is connected to the drive unit 400.

[0081] Step S112: Conduct a wind resistance test.

[0082] The track 200 limit position improves the stability of the pole 311. The flexible material of the flexible tarpaulin 320 is combined with the telescopic frame 310 to connect the wind-resistant structure. The greater the negative wind pressure, the stronger the self-locking force.

[0083] In summary, the technical effects of the rebar processing shed 10 with a retractable flexible roof provided by this embodiment of the present invention include: The rebar processing shed 10 with a retractable flexible roof provided in this embodiment of the invention uses a drive device 400 to drive a telescopic frame 310 to extend and retract. During extension and retraction, the telescopic frame 310 moves linearly along a track 200, causing the flexible tarpaulin 320 to fold or unfold. When large rebars need to be hoisted, the drive device 400 can drive the telescopic frame 310 to retract, causing the flexible tarpaulin 320 to fold, thus expanding the working space and facilitating the hoisting and processing of large rebars. When large rebar hoisting is not required, the drive device 400 can drive the telescopic frame 310 to extend, causing the flexible tarpaulin 320 to unfold, thus reducing the working space and meeting operational needs.

[0084] Therefore, the steel bar processing shed 10 with a retractable flexible roof has at least the following advantages: 1. It allows for flexible adjustment of the working space and coverage area, adapting to the processing needs of steel bars at different heights (such as hoisting with large cranes), avoiding the problem of temporary dismantling of traditional fixed canopies, reducing safety risks and modification costs. The retractable flexible canopy 300 can be extended or retracted at any time according to construction needs, expanding or shrinking the working space, facilitating the hoisting and processing of large steel bars, and improving construction efficiency.

[0085] 2. Optimized construction efficiency and mobility: It can realize modular production and transportation. The flexible tarpaulin 320 is foldable, reducing the transportation volume and effectively reducing transportation costs. It can realize factory prefabrication of modules (such as flexible tarpaulin 320 foldable packaging, drive system pre-testing) and on-site bolt connection of frames, reducing assembly complexity.

[0086] 3. Enhanced safety: The retractable flexible canopy 300 can effectively buffer loads such as strong winds and snow accumulation, reducing the risk of damage to the steel processing shed due to extreme weather, and ensuring the safety of construction personnel and equipment.

[0087] 4. Easy to assemble and disassemble: The support frame 100 can be modularly designed, which is convenient for quick assembly and disassembly; the retractable flexible canopy 300 is also easy to install and disassemble, reducing construction difficulty and cost.

[0088] 5. Green Construction: The steel reinforcement processing shed has a sturdy and durable overall structure, and its components can be reused multiple times, conforming to the concepts of energy conservation, environmental protection, and sustainable development. Modular design reduces material waste and meets energy conservation and environmental protection requirements.

[0089] 6. Multifunctional integration and enhanced protection: The flexible tarpaulin 320 uses weather-resistant materials (plastic-coated fiberglass cloth (weight ≥800g / ㎡), with a PVDF coating on the surface, weather resistance for more than 10 years, and tensile strength ≥25kN / m).

[0090] 7. In case of heavy snow or strong winds, the steel bar processing shed can be retracted into individual units to reduce the working surface and facilitate protection and reinforcement.

[0091] In addition, the steel bar processing shed 10 with a retractable flexible roof has the following advantages: 1. Modular telescopic structure (manual mode): The drive unit 400 controls the folding and unfolding of the flexible tarpaulin 320, and works in conjunction with the X-shaped telescopic rod group 312 (4cm×8cm, bolted connection at 1m intervals) to achieve stable telescopic extension and retraction; the operator controls the telescopic flexible canopy 300 to extend and retract via remote control or the button of the drive unit 400, supporting independent adjustment of a single unit and linkage of multiple units.

[0092] 2. Track 200 structure: 200 longitudinal tracks of No. 20 I-beams support the retractable flexible canopy 300 movement, and 120 uprights of No. 14 I-beams are connected by cross diagonal support rods of No. 130 to ensure the overall rigidity after the connection of each unit.

[0093] 3. Integrated moving and leveling system: The bottom of the 311 pole integrates a hydraulic height adjustment device and universal casters with brakes. Combined with the self-drive moving system and the option of pre-embedded track 200, it can achieve flexible relocation and adaptability to the ground.

[0094] 4. Multi-protection integrated design: 300-layer structure of retractable flexible canopy: using weather-resistant materials and hot-press molding process to ensure sealing and weather resistance; 5. Support truss 370 reinforcement: A support truss 370 with 4×8cm square steel pipes 30cm high is installed on the roof to enhance impact resistance.

[0095] 6. Intelligent function control: Remote control operation allows for 300° folding or unfolding of the retractable flexible roof, combined with movable and ventilation louvers, equipped with overload protection shutdown alarm function, and sensors and navigation software to achieve obstacle avoidance and path planning.

[0096] 7. Standardized manufacturing and assembly processes: Factory prefabrication of modules (such as flexible tarpaulin 320 fold packaging, drive device 400 pre-testing), on-site bolt connection of frames, reducing assembly complexity.
