Technical Field

[0001] This utility model relates to steel strand construction equipment, specifically a quick-installation storage rack for steel strands. Background Technology

[0002] In the current construction field, steel strands are mainly used in prestressed load-bearing applications and are widely used. Steel strands are typically used in rolls during construction. To ensure safety and stability during use, a specific storage and retrieval bracket is required on-site for easy fixing and tensioning. Existing steel strand storage and retrieval brackets include: Patent No. CN209127788U (authorization announcement date: July 19, 2019), entitled "A Steel Strand Bracket"; Patent No. CN220744886U (authorization announcement date: April 9, 2024), entitled "A Steel Strand Unwinding Bracket with a Conical Protective Cage"; and Patent No. CN223149935U (authorization announcement date: July 25, 2025), entitled "A Portable, Weld-Free Storage and Retrieval Bracket for Prestressed Steel Strands". The above-disclosed storage racks for steel strand coils offer convenient access, but their main drawbacks are: they require on-site assembly, which is time-consuming and labor-intensive; furthermore, they necessitate disassembly and packaging for transport, as their large size makes them difficult to handle. Overall, the assembly and disassembly process remains cumbersome and inconvenient. Therefore, improvements to existing steel strand storage racks are needed. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a quick-installation storage rack for steel strands, thereby solving the technical problem that existing similar steel strand storage racks are inconvenient to disassemble, use, and transport. This objective is achieved through the following technical solution.

[0004] A quick-assembly storage rack for steel strands includes a front support group and a rear support group, forming a storage space for storing and retrieving steel strand coils. The front support group includes a left support, a right support, an upper movable support, and a lower movable support. The key structural feature is that the left and right supports are symmetrical. The upper movable support includes a left swing plate, a middle plate, and a right swing plate. One end of the left swing plate is hinged to the top of the left support, and the other end is hinged to one end of the middle plate. The other end of the middle plate is hinged to one end of the right swing plate, and the other end of the right swing plate is hinged to the top of the right support. The left and right swing plates are evenly spaced along their respective lengths with rod holes. The lower movable support is symmetrical to the upper movable support within the front support group. One end of the left swing plate of the lower movable support is hinged to the left support... The bottom of the frame is hinged, and one end of the right swing plate of the lower movable support is hinged to the bottom of the right support. The rear support group is symmetrical to the front support group. The upper and lower intermediate plates of the front and rear support groups are parallel, and the upper and lower intermediate plates are connected by a pair of parallel long screws and nuts to form a tension connection. A steel strand tension guide bracket is slidably sleeved between the two long screws of the front support group and / or the rear support group, and the upper and lower ends of the slidable sleeve are locked and fixed by nuts. Screws are inserted between the rod holes of the left swing plates and the right swing plates of the front and rear horizontally opposite groups, and the two ends of the screws are connected to nut seats to form a locking fixation. When the screws between the front and rear support groups are tightened with the upper and lower intermediate plates, they clamp and fix the circumference of the steel strand coil. With the above structure, the upper and lower movable brackets can be adjusted by swinging, and the spaced rod holes and screws can be used to clamp and limit steel strands of different outer diameters. The upper and lower middle plates are tightened by the long screws, thereby stabilizing the clamping state and achieving stable support for the steel strands. The structure is easy to assemble and disassemble, and can also be folded and stored after use to reduce space occupation and facilitate handling.

[0005] Both the left and right supports are U-shaped channel steels, and one end of each of the left and right swing plates is movably hinged within the U-shaped groove of the U-shaped channel steel. Furthermore, both the left and right supports have an integral support base plate welded to their bottoms. This structure helps improve the overall stability of the support system.

[0006] When the left and right swing plates are swung into position relative to their corresponding left and right supports, they are completely embedded in the U-shaped groove of the U-shaped channel steel. This structure allows the storage rack to be disassembled and folded in a smaller volume.

[0007] The steel strand tensioning guide bracket is conical, and its circumferential surface at the large hole end is provided with symmetrical sliding seats. The sliding seats on both sides slide and engage with the long screws on both sides, and the upper and lower ends of the sliding seats are connected to the long screws through nuts to form locking and limiting positions. This structure allows for easy adjustment of the height position of the steel strand tensioning guide bracket to match the requirements of steel strand tensioning guidance.

[0008] Each of the left and right brackets has at least one horizontal insertion plate on one side. When the screw is not in use, it is vertically inserted into the insertion plate, and the upper end of the screw is connected to the nut seat, which is positioned above the insertion plate. This structure facilitates the insertion and connection of the screw and nut seat with the left and right brackets during disassembly, prevents loss, and makes storage and transportation convenient.

[0009] The overall structure of this utility model is relatively simple and reliable, and it is convenient to adjust, disassemble and use. It is easy to fix and support steel strand coils of different sizes. After use, it can be folded up to reduce space occupation, which is convenient for storage and handling. It is suitable as a steel strand storage bracket in the construction field, or as a structural improvement of similar storage brackets. Attached Figure Description

[0015] The present invention will now be further described with reference to the accompanying drawings.

[0016] like Figures 1-3As shown, the quick-assembly storage rack for steel strands includes a front support group and a rear support group, forming a storage space for storing and retrieving steel strand coils between the front and rear support groups. The front support group includes a left support 1, a right support 8, an upper movable support, and a lower movable support. The left and right supports are symmetrically structured. The upper movable support includes a left swing plate 4, a middle plate 5, and a right swing plate 6. One end of the left swing plate is movably hinged to the top of the left support, and the other end of the left swing plate is movably hinged to one end of the middle plate. The other end of the middle plate is movably hinged to one end of the right swing plate, and the other end of the right swing plate is movably hinged to the top of the right support. The left and right swing plates are evenly spaced with rod holes 7 along their respective length directions. The lower movable support is symmetrical to the upper movable support in the front support group. One end of the left swing plate of the lower movable support is movably hinged to the bottom of the left support, and one end of the right swing plate of the lower movable support is movably hinged to the bottom of the right support. The front and rear support groups are symmetrically connected by a hinge. The upper and lower intermediate plates in both groups are parallel, and a pair of parallel long screws 11 connected to a nut 14 form a tensioned connection. A steel strand tension guide bracket 12 is slidably sleeved between the two long screws of the front and / or rear support groups, and the upper and lower ends of the slidable sleeve are locked and fixed by nuts 13. Screws 9 are threaded through the rod holes of the horizontally opposite left and right swing plates in both the front and rear support groups, and are locked and fixed by nut seats 10 at both ends. When the screws between the front and rear support groups are tensioned along with the upper and lower intermediate plates, they clamp and fix the circumference of the steel strand coil.

[0017] Furthermore, both the left support 1 and the right support 8 are U-shaped channel steels, and one end of the left swing plate 4 and the right swing plate 6 are movably hinged within the U-shaped groove of the U-shaped channel steel. Additionally, an integral support base plate 2 is welded to the bottom of both the left and right supports. To make the storage rack smaller and more stable after disassembly and folding, the left and right swing plates are fully embedded within the U-shaped groove of the U-shaped channel steel when folded relative to the left and right supports.

[0018] Furthermore, the aforementioned steel strand tension guide bracket 12 is tapered, and the circumferential surface of the large hole end is provided with symmetrical sliding seats 1201. The sliding seats on both sides are slidably engaged with the long screws 11 on both sides, and the upper and lower ends of the sliding seats are connected to the long screws through the nut parts 13 to form a locking limit.

[0019] Furthermore, each of the aforementioned left bracket 1 and right bracket 8 is provided with at least one horizontal socket plate 3. When the screw 9 is not in use, it is vertically inserted into the socket plate, and the upper end of the screw is connected to the nut seat 10, which is located above the socket plate.

[0020] When using this quick-installation storage rack for steel strands, first place the steel strand roll between the front and rear rack groups. Then, push the left rack 1 and right rack 8 close to the steel strand roll. Next, insert the screw 9 into the horizontally opposite rod holes 7 of the front and rear rack groups. The two ends of the screw are tightened through the connecting nut seat 10, thus limiting the ends of the steel strand roll by the front and rear rack groups. Next, the upper and lower intermediate plates 5 of the front and rear rack groups are tightened by the long screw 11 and the nut 14. After tightening, each screw abuts against the circumference of the steel strand roll, thus effectively limiting the circumference of the steel strand. The steel strand tension guide rack 12 in the front rack group slides and adjusts with the long screw through the sliding seats 1201 on both sides. After adjustment, the nut 13 locks the long screw to limit the ends of the sliding seats, fixing the steel strand guide rack at the required height. The steel strand inside the steel strand roll can then be pulled out from the conical hole of the steel strand tension guide rack for use. The above completes the support and fixation of the steel strand coil.

[0021] like Figure 4 As shown, when disassembly and folding are required, simply reverse the above-mentioned operation, remove the screw and place it into the corresponding socket plate 3 of the left and right brackets, and limit the top of the screw to the nut seat above the socket plate; the left and right brackets in the front bracket group and the rear bracket group are folded inwards, and the front bracket group and the rear bracket group are folded directly back and forth. After folding, the overall volume is small, which is convenient for storage and transportation.

[0022] The above description is intended to illustrate the technical means of this utility model and is not intended to limit the technical scope of this utility model. Any obvious improvements or substitutions made to this utility model by those skilled in the art based on existing common knowledge also fall within the protection scope of the claims of this utility model.
