Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and specifically to an A-shaped storage rack for prefabricated wall panels. Background Technology

[0002] In the field of precast component production and processing, precast components are steel, wood, or concrete components prefabricated in factories or construction sites according to design specifications. Among them, there are many shortcomings in the existing equipment and operating methods for the production, storage, and transportation of slab precast components.

[0003] Currently, the movement of precast slab components relies on lifting equipment, which can only lift and transport one component at a time. This single-lift mode is extremely inefficient and severely restricts production progress, especially given the increasing demand for precast components and the expanding scale of production. Taking large-scale construction projects as an example, if a large number of precast slab components need to be assembled quickly, frequent single-lifts not only consume a lot of time but also lead to excessive use of lifting equipment, increasing equipment wear and tear and maintenance costs, and significantly impacting the overall project progress efficiency. Utility Model Content

[0004] In view of the above-mentioned prior art, in order to solve the problem that only one component can be lifted and transported at a time, and the efficiency of the single lifting mode is extremely low, this application proposes an A-shaped storage rack for precast wall panels.

[0005] This application provides an A-shaped storage rack for precast wall panels, employing the following technical solution: An A-shaped storage rack for prefabricated wall panels is characterized by comprising an upper beam and a base frame. At least two A-frames are arranged in an array at intervals along the length of the lower part of the upper beam. The bottom end of each A-frame is connected to the base frame. Two placement plates are provided on the base frame, and the two placement plates are located on both sides of the A-frames. The top surface of each placement plate is inclined towards the A-frames, and the inclination angle between the top surface of the placement plate and the horizontal direction is 15-25 degrees.

[0006] By adopting the above technical solution, the arrangement of multiple A-frames enhances the overall support capacity of the storage rack, enabling it to withstand the weight of more precast wall panels. The array-spaced distribution ensures uniform support and improves the stability of the storage rack. The inclined placement of the mounting plate increases the contact area with the bottom surface of the panel component, allowing the bottom surface of the precast wall panel to fully adhere to the mounting plate during placement, forming a larger support surface and significantly improving the stability of the component placement.

[0007] Preferably, the base frame includes horizontal bars and vertical bars, the horizontal bars and the vertical bars are connected perpendicularly, two horizontal bars are spaced apart, four vertical bars are provided, the vertical bars are perpendicularly intersecting the horizontal bars, the four vertical bars are equidistantly distributed on the two horizontal bars, and the bottom end of the A-frame is fixedly connected to the vertical bars.

[0008] By adopting the above technical solution, the horizontal and vertical bars intersect perpendicularly to form a stable frame structure, providing a solid foundation for the entire storage rack. Two horizontal bars and four equidistant vertical bars ensure balanced force distribution on the base frame in all directions, improving its load-bearing capacity. The A-frame is fixedly connected to the vertical bars, allowing the supporting force of the A-frame to be stably transferred to the base frame, further enhancing the overall structural stability of the storage rack and ensuring that the storage rack will not deform or be damaged due to uneven force during the placement and hoisting of prefabricated wall panels.

[0009] Preferably, a stair crossbar is provided on the A-frame located at the end of the upper crossbeam.

[0010] By adopting the above technical solution, the stair rails provide a climbing passage for workers, making it convenient for them to climb to a suitable height when storing, inspecting, and maintaining precast wall panels, without the need for other complicated climbing equipment, thus greatly improving the convenience and efficiency of the work.

[0011] Preferably, the A-frame with a stair rail near the end of the upper crossbeam is also equipped with a handrail.

[0012] By adopting the above technical solution, the handrail provides additional safety for workers climbing the staircase crossbars. Workers can hold onto the handrail while climbing to maintain their balance, effectively reducing the risk of accidents caused by accidental slips and greatly improving the safety of operators working at heights, thus ensuring their personal safety.

[0013] Preferably, the two placement plates are arranged parallel to the crossbar, and the two placement plates are fixedly installed at both ends of the top surface of the four longitudinal bars and located on both sides of the A-frame.

[0014] By adopting the above technical solution, the placement plate is set parallel to the crossbars, ensuring the stability of the placement plate on the base frame and preventing it from shifting or swaying. The placement plate is fixedly installed at both ends of the top surface of the four longitudinal bars and on both sides of the A-frame. This layout allows the placement plate to fully utilize the base frame structure for support and works in conjunction with the A-frame to provide a stable placement environment for the precast wall panels. Simultaneously, the placement plates on both sides of the A-frame allow for symmetrical placement of precast wall panels, further ensuring the overall balance of the storage rack and preventing tilting due to heavy loads placed on one side.

[0015] Preferably, a protective fence is fixedly installed on the upper crossbeam, and the protective fence is arranged along the length of the upper crossbeam.

[0016] By adopting the above technical solutions, the protective fence can effectively prevent construction workers at the top of the scaffolding from accidentally slipping off. When workers are performing work at heights, the protective fence acts as a safety barrier, providing reliable protection for the workers, significantly improving the safety of the working environment, reducing the probability of accidents, and ensuring safe production at the construction site.

[0017] Preferably, a connecting block is provided at both ends of the upper crossbeam along its length. The connecting block passes through the upper crossbeam. A positioning platform is provided on both sides of the connecting block. A first fixing hole is provided on both positioning platforms. A second fixing hole communicating with the first fixing hole is provided on the upper crossbeam. A bolt is inserted in the first fixing hole and the second fixing hole. A washer and a double-ended nut are provided on the bolt.

[0018] By adopting the above technical solution, and through the coordinated use of connecting blocks, positioning platforms, first fixing holes, second fixing holes, bolts, washers, and double-ended nuts, the connecting blocks can be firmly fixed to the upper crossbeam. This connection method not only facilitates the installation and disassembly of the connecting blocks, but also ensures that during the hoisting of the storage rack, the connecting blocks can stably withstand the tensile force of the hoisting device and evenly transfer the tensile force to the upper crossbeam, thereby distributing it throughout the entire storage rack structure. This ensures the structural integrity and stability of the storage rack during hoisting and avoids hoisting accidents caused by insecure connections.

[0019] Preferably, the connecting block has a through-hole.

[0020] By adopting the above technical solution, the connection hole provides a connection position for the lifting hook of the lifting device. After the prefabricated components are placed on the frame, the lifting hook of the lifting device can pass through the connection hole and connect to the storage rack.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The arrangement of multiple A-frames enhances the overall support capacity of the storage rack, allowing it to withstand the weight of more precast wall panels. The array-spaced distribution ensures uniform support and improves the rack's stability. The inclined placement of the mounting plate increases the contact area with the bottom surface of the panel component, ensuring the bottom of the precast wall panel fits snugly against the mounting plate, creating a larger support surface and significantly improving the stability of the component placement. 2. The perpendicular intersection of the horizontal and vertical bars forms a stable frame structure, providing a solid foundation for the entire storage rack. Two horizontal bars and four equidistant vertical bars ensure balanced stress distribution on the base frame in all directions, improving its load-bearing capacity. The A-frame is fixedly connected to the vertical bars, allowing the supporting force of the A-frame to be stably transferred to the base frame, further enhancing the overall structural stability of the storage rack and ensuring that the storage rack will not deform or be damaged due to uneven stress during the placement and hoisting of prefabricated wall panels. 3. The connection hole provides a connection point for the lifting device's hook. After the prefabricated components are placed on the frame, the lifting device's hook can pass through the connection hole and connect to the storage rack. Attached Figure Description

[0024] This application discloses an A-shaped storage rack for prefabricated wall panels.

[0025] An A-frame storage rack for precast wall panels includes a base frame 1 and an upper crossbeam 2. The base frame 1 is horizontally positioned parallel to the ground, and the upper crossbeam 2 is horizontally positioned above and parallel to the base frame 1. Multiple A-frames 3 are arranged in an array at intervals along the length of the upper crossbeam 2, with the bottom ends of the A-frames 3 fixedly connected to the base frame 1. Stair rails 4 are installed on the A-frames 3 located at the ends of the upper crossbeam 2. These stair rails allow workers to climb to a suitable height when storing, retrieving, inspecting, and maintaining precast wall panels. The stair rails also provide lateral support and reinforcement to the inclined beams at both ends, further enhancing the structural strength of the storage rack.

[0026] Specifically, the base frame 1 includes horizontal bars 11 and vertical bars 12, which are connected perpendicularly. Two horizontal bars 11 are spaced apart, and four vertical bars 12 are arranged, intersecting perpendicularly with the horizontal bars 11. Two vertical bars 12 are fixed to the ends of two horizontal bars 11, and the other two are evenly distributed along the sides of the two horizontal bars 11. The bottom end of the A-frame 3 is fixedly connected to the vertical bars 12, and handrails are also provided on the A-frame 3 near the end of the upper crossbeam 2.

[0027] Furthermore, a protective railing 5 is fixedly installed on the upper crossbeam 2. The protective railing 5 can effectively prevent construction workers at the top of the scaffold from accidentally slipping off the scaffold, thereby improving the safety of the construction environment for the workers.

[0028] Specifically, the base frame 1 also includes placement plates 13, which are arranged parallel to the crossbars 11 and have the same length as the crossbars 11. There are two placement plates 13, which are fixedly installed at both ends of the top surface of the four longitudinal bars 12 and located on both sides of the A-frame 3, and the placement plates 13 are inclined. The side of the placement plate 13 away from the A-frame 3 is higher than the side of the placement plate 13 close to the A-frame 3, and the top surface of the placement plate 13 faces the A-frame 3. The inclination angle between the top surface of the placement plate 13 and the horizontal direction is 20 degrees. The inclined setting of the placement plate 13 can increase its contact area with the bottom surface of the plate component. When the precast plate component is placed on the frame, one side of the precast plate component rests on the inclined beam of the A-frame, and the bottom surface of the precast plate component can fully fit with the inclined top surface of the placement plate 13 to form a larger support surface, thereby significantly improving the stability of the component placement. The inclination angle between the top surface of the placement plate 13 and the horizontal direction can be selected from 15-25 degrees. In this embodiment, the inclination angle between the placement plate 13 and the horizontal direction is selected as 20 degrees.

[0029] Specifically, connecting blocks 6 are provided at both ends of the upper crossbeam 2 along its length. The connecting blocks 6 penetrate the upper crossbeam 2. Positioning platforms 7 are provided on both sides of the connecting blocks 6. First fixing holes 8 are provided on both sides of the positioning platforms 7. Second fixing holes 9 are provided on the upper crossbeam 2 and are connected to the first fixing holes 8. Bolts are installed through the first fixing holes 8 and the second fixing holes 9. The bolts pass through the first fixing holes 8 and the second fixing holes 9 and extend from the side of the upper crossbeam 2 away from the connecting blocks 6. Washers and double-ended nuts are provided on the bolts. The connecting blocks 6 are firmly fixed to the upper crossbeam 2 by tightening the double-ended nuts.

[0030] Furthermore, a connecting hole 10 is provided through the connecting block 6. By providing the connecting hole 10, when the completed prefabricated components are placed on the frame, the lifting hook of the lifting device can pass through the connecting hole 10 and connect to the storage rack when the entire frame is lifted by the lifting device for handling or transfer.

[0031] The implementation principle of the application embodiment is as follows: A stable frame is formed by the horizontal bars 11 and vertical bars 12 of the base frame 1. The A-frame supports the upper beam 2 to form an A-shaped structure, and multiple A-frames enhance the overall support capacity and stability. The placement plate 13 is inclined at 15-25 degrees to increase the contact area with the bottom surface of the precast wall panel, so that the bottom surface of the placement plate 13 is fully attached to the placement plate 13, improving the stability of the component placement. The A-frame at the end of the upper beam 2 is equipped with a stair crossbar 411 and a handrail to facilitate workers' climbing operations, and the protective railing 5 ensures the safety of working at heights. The connecting blocks 6 at both ends of the upper beam 2 are fixed by bolts, washers and double-sided nuts. The connecting holes 10 on the connecting blocks 6 allow the lifting hook of the lifting device to pass through, realizing the overall lifting of the storage rack, thereby solving the problem of low efficiency in the existing single lifting of precast wall panels. Multiple precast wall panels can be lifted at one time, improving the lifting efficiency.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
