Description

Technical Field

[0001] The embodiments of this utility model relate to the field of emergency rescue and disaster relief technology, specifically, to a foldable steel cage. Background Technology

[0002] In flood control, emergency rescue, and other disaster relief scenarios, steel cages are important equipment used for reinforcing the slope toe of dikes and sealing breaches. By filling them with stones or sandbags, they are tightly fixed by their own structure, which can effectively resist water erosion and enhance the stability of the dike.

[0003] However, the widely used gabion mesh and wire mesh rebar cages on the market have significant drawbacks. Fixed rebar cages, due to their fixed structure, cannot be folded or collapsed, requiring substantial space for storage and increasing transportation difficulty and cost due to their large size, hindering efficient bulk transport. Furthermore, the low strength of gabion mesh makes it unable to withstand the weight of filler materials such as stones, or the tensile forces generated during hoisting, thus preventing its movement. Therefore, when repositioning or moving the gabion mesh as a whole is necessary, significant manpower and resources are required for disassembly and reinstallation, increasing construction procedures and time costs, and potentially damaging the gabion mesh itself, affecting its subsequent performance.

[0004] While on-site assembled steel cages alleviate transportation issues to some extent, their practical use requires workers to assemble components on-site. This process is not only cumbersome and time-consuming, but also demands a certain level of skill from the assemblers. In emergencies such as flood control, time is of the essence. This on-site assembly method can severely delay rescue efforts, failing to meet the needs of rapid response to emergencies and potentially leading to further escalation of the danger.

[0005] These problems make it difficult for existing steel cages to fully play their due role in emergency rescue tasks such as flood control, thus hindering the efficiency of rescue and disaster relief work. Utility Model Content

[0006] To overcome the above-mentioned defects, the embodiments of this utility model provide a foldable steel cage, which solves the technical problem that the steel cage is large in size and inconvenient to transport in the prior art.

[0007] According to one aspect, at least one embodiment of the present invention provides a foldable steel cage, comprising:

[0008] A bottom mesh sheet, the bottom mesh sheet including a plurality of first support rods distributed circumferentially around the bottom mesh sheet, the bottom mesh sheet being used to support the filling material;

[0009] The load-bearing side mesh is rotatably mounted on the first support rod. The load-bearing side mesh can switch between a storage state and a load-bearing state by rotating. In the load-bearing state, multiple load-bearing side meshes can enclose each other to form an enclosing space to carry the filling material, or multiple load-bearing side meshes can rotate towards the bottom mesh to be in a storage state.

[0010] For example, in a folding steel cage provided in at least one embodiment of the present invention, the bottom mesh further includes a second support rod, the second support rod and the first support rod are alternately distributed in the circumference of the bottom mesh, and the second support rod is rotatably provided with a connecting side mesh;

[0011] The connecting side mesh can rotate to form the enclosing space together with the supporting side mesh, or it can rotate towards the bottom mesh to be in a stored state.

[0012] For example, in a folding steel cage provided by at least one embodiment of the present invention, the number of the first support rod and the second support rod are both two sets, and each set of the first support rod and the second support rod has multiple sets. The two sets of the first support rod and the two sets of the second support rod are relatively distributed in the circumference of the bottom mesh.

[0013] For example, in a folding rebar cage provided in at least one embodiment of the present invention, the bearing-side mesh is provided with ear pieces at one end on both sides for connecting with the connecting-side mesh. The ear pieces are arranged in pairs, and the ear pieces in a pair are spaced apart to form a limiting space for accommodating the end of the connecting-side mesh. The ear pieces are provided with connecting holes, and the connecting holes are used to install connecting pins to seal the limiting space.

[0014] For example, in at least one embodiment of the present invention, a folding and unfolding steel cage further includes:

[0015] Top mesh panel one, one end of which is hinged to a connecting side mesh panel.

[0016] Top mesh piece two, one end of which is hinged to another connecting side mesh piece, and top mesh piece one and top mesh piece two can rotate and be located on the opposite side of the bottom mesh piece to block the enclosed space.

[0017] For example, in a folding rebar cage provided in at least one embodiment of the present invention, a mounting block is provided on the top mesh plate one, and two symmetrical mounting plates are provided on the mounting block one. The mounting plate one is provided with a mounting hole one for inserting fasteners; the rebar of the top mesh plate two, which is close to the top mesh plate one, can be inserted between the two mounting plates.

[0018] For example, in a folding rebar cage provided in at least one embodiment of the present invention, the top mesh plate 2 is provided with an installation block 2, the installation block 2 is provided with two symmetrical installation plates 2, the installation plates 2 are provided with installation holes 2, the installation holes 2 are used to insert fasteners, and the rebar of the bearing side mesh plate and the end of the top mesh plate 1 that is close to the top mesh plate 1 can be inserted between the two installation plates 2.

[0019] For example, in a folding rebar cage provided in at least one embodiment of the present invention, the bottom mesh further includes a support member, which is vertically disposed on the outer peripheral wall of the bottom mesh and is used to support the upper rebar cage when multiple rebar cages are stacked.

[0020] For example, in a folding rebar cage provided in at least one embodiment of the present invention, a limiting plate is provided at the upper end of the support member, and a limiting space for accommodating the upper rebar cage is formed between multiple limiting plates, and a hoisting hole is provided on the limiting plate.

[0021] For example, in a folding rebar cage provided in at least one embodiment of the present invention, an abutment plate is also provided on the connecting side mesh, the abutment plate being used to support the upper rebar when the rebar cage is in a retracted state.

[0022] The beneficial effects of the embodiments of this utility model are as follows:

[0023] In this invention, multiple first support rods of the bottom mesh provide stable rotational support for the load-bearing mesh. When under load, they can enclose and form a surrounding space to firmly support stones or sandbags and other filling materials. By tightly fixing these filling materials, they effectively resist water erosion and ensure the effectiveness of flood control operations such as dam reinforcement and breach sealing.

[0024] When in its stowed state, multiple load-bearing side mesh panels rotate towards the bottom mesh panel, significantly reducing the overall space occupied. This compact stowage design greatly facilitates storage and transportation, not only saving transportation space, increasing the volume of goods transported at one time, and reducing transportation costs, but also making storage more convenient and saving warehouse space.

[0025] Meanwhile, compared with on-site assembled steel cages, this foldable steel cage is easy to deploy and can be quickly deployed for flood control and disaster relief work. It can respond quickly in emergency situations, significantly improve the efficiency of flood control operations, and buy valuable time for disaster relief. Attached Figure Description

Detailed Implementation

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0036] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0037] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0040] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0041] like Figures 1-7 As shown, it illustrates a folding steel cage in one embodiment of the present invention.

[0042] like Figures 1-3As shown, the bottom mesh 100 is used to support the filling material and includes multiple sets of first support rods 101, which are distributed circumferentially around the bottom mesh 100. Each load-bearing mesh 200 is rotatably connected to a corresponding set of first support rods 101. This rotatable connection can be achieved through a shaft-hole fit, that is, the horizontally arranged steel bar at the lowest end of the load-bearing mesh 200 is inserted into the hole on the first support rod 101, allowing the load-bearing mesh 200 to rotate around the first support rod 101. When the steel cage is needed to support the filling material, the supporting side mesh 200 is rotated to the supporting state. At this time, multiple supporting side meshes 200 cooperate with each other to form a closed enclosed space. The filling material can be placed in this enclosed space, supported by the bottom mesh 100 and surrounded by the supporting side meshes 200. When transportation or storage is required, multiple supporting side meshes 200 are rotated to the side closer to the bottom mesh 100, so that the supporting side meshes 200 are close to the bottom mesh 100, thereby reducing the overall volume of the steel cage and saving space.

[0043] The bottom mesh 100 is also provided with a second support rod 102. The second support rod 102 and the first support rod 101 are alternately distributed around the bottom mesh 100. A connecting side mesh 300 is rotatably mounted on the second support rod 102. When it is necessary to form an enclosed space to carry the filling, the connecting side mesh 300 rotates to cooperate with the carrying side mesh 200 to jointly enclose and form an enclosed space. When it is necessary to store, the carrying side mesh 200 and the connecting side mesh 300 rotate towards the side closer to the bottom mesh 100. After rotation, the connecting side mesh 300 and the carrying side mesh 200 are parallel to the bottom mesh 100, thus saving longitudinal space. There are two sets of first support rods 101 and two sets of second support rods 102. The two sets of first support rods 101 are relatively distributed around the bottom mesh 100, and the two sets of second support rods 102 are also relatively distributed, making the bottom mesh 100 structure symmetrical and the distribution of the carrying side mesh 200 and the connecting side mesh 300 more balanced. The holes on the two first support rods 101 and the two second support rods 102 are at different heights, providing different rotational mounting references for the load-bearing side mesh 200 and the connecting side mesh 300. This avoids mutual interference and stacking of the connecting side mesh 300 and the mounting side mesh when they are stored, further compressing the overall storage volume and making the storage more compact, which is more conducive to transportation and storage.

[0044] The bearing-side mesh 200 has ear pieces 201 at one end connecting to the connecting-side mesh 300 on both sides. Multiple sets of ear pieces 201 are longitudinally arranged along the end of the bearing-side mesh 200, with two ear pieces 201 in each set forming a limiting space. The end of the connecting-side mesh 300 can be inserted into this limiting space. After installing a connecting pin in the connecting hole 2011 of the ear piece 201, the end of the connecting-side mesh 300 is fixed within the limiting space, thus connecting the bearing-side mesh 200 and the connecting-side mesh 300. The end of the horizontal rib of the connecting-side mesh 300 has a hook with a connecting vertical rib. When connecting the bearing-side mesh 200 and the connecting-side mesh 300, the connecting vertical rib can be inserted into the limiting space, and then the connecting pin can be inserted into the mounting hole of the ear piece 201 to restrict the movement of the connecting vertical rib, thus connecting the bearing-side mesh 200 and the connecting-side mesh 300.

[0045] Based on the above structure, such as Figures 4-6 As shown, this reinforcing cage also includes a top mesh panel 400 and a second top mesh panel 500. One end of the first top mesh panel 400 is hinged to a connecting side mesh panel 300, and one end of the second top mesh panel 500 is hinged to another connecting side mesh panel 300. The first top mesh panel 400 and the second top mesh panel 500 can rotate 270° around the hinge point. When the first top mesh panel 400 and the second top mesh panel 500 are in the retracted state, they overlap with the connecting side mesh panels 300. After the enclosed space is filled with flood control materials such as stones or sandbags, the first top mesh panel 400 and the second top mesh panel 500 are rotated 270° around their hinge point until they are parallel to the bottom mesh panel 100, thus sealing off the enclosed space.

[0046] The mounting block 401 on the top mesh sheet 400 has two symmetrical mounting plates 4010, and mounting plates 4010 have mounting holes 4011. The reinforcing bars of the top mesh sheet 500 near one end of the top mesh sheet 400 are inserted between the two mounting plates 4010. The connection and fixation of the top mesh sheet 400 and the top mesh sheet 500 are achieved by inserting fasteners into the mounting holes 4011.

[0047] The mounting block 401 on the top mesh 2 500 has two symmetrical mounting plates 2 5010, each with mounting holes 2 5011. The reinforcing bars of the bearing-side mesh 200 near one end of the top mesh 2 400 are inserted between the two mounting plates 2 5010, and fasteners are inserted into the mounting holes 2 5011 to fix the top mesh 2 500 to the bearing-side mesh 200. Positioning pins can be used for the fasteners of mounting blocks 1 401 and 2 501.

[0048] In this example, the positions of mounting block 401 and mounting block 501 can be adjusted. When stones are placed in the steel cage, the cage will deform to a certain extent due to the large size of the stones, resulting in a large gap between top mesh plate 400 and top mesh plate 500. This makes it impossible for mounting blocks 401 and 501 to be locked in their original positions. Workers can find a suitable connection point by changing the positions of mounting blocks 401 and 501 according to the actual docking angle of top mesh plate 400 and top mesh plate 500, and then fix the steel cage. This prevents the cage from expanding after stones are placed in the cage and failing to lock properly.

[0049] like Figure 1 and Figure 7 As shown, the outer periphery of the bottom mesh 100 is vertically provided with a support member 103. When multiple reinforcing cages are stacked, the bottom of the upper reinforcing cage contacts the support member 103, and the support member 103 provides support for the upper reinforcing cage. The support member 103 can be set as an angle steel structure. The angle steel is right-angled, and the two mutually perpendicular limbs form a stable force-bearing structure, which can provide solid support for the stacked upper reinforcing cage, effectively bear the weight of the upper reinforcing cage and the internal filling, ensure the stability of the overall structure in the stacked state, and is not easy to deform due to excessive force. Its flat limbs can be stably connected to the outer periphery of the bottom mesh 100. The connection method is simple and firm, and can be closely fitted to the structure of the bottom mesh 100, ensuring that the support member 103 and the bottom mesh 100 form an integral force-bearing system, improving the reliability of the support.

[0050] The support member 103 has a limiting plate 1030 at its upper end. Multiple limiting plates 1030 form a limiting space. When multiple reinforcing cages are stacked in the retracted state, the upper reinforcing cage falls into this space and is limited by the limiting plate 1030. The lifting hole 1031 on the limiting plate 1031 can be used to lift the reinforcing cage. The connecting side mesh 300 has an abutment plate 301. When the reinforcing cage is in the retracted state, the abutment plate 301 contacts the upper reinforcing bar, providing support and preventing the structure from becoming messy and damaged during retraction.

[0051] In some examples, the unfolding process of this steel cage is as follows: First, the two connecting side meshes 300 are rotated and unfolded around the second support rod 102 in a direction away from the bottom mesh 100. Then, the two bearing side meshes 200 are unfolded around the first support rod 101 in a direction away from the bottom mesh 100, so that the connecting vertical bars at the ends of the connecting side meshes 300 are inserted into the limiting space formed by each set of ear pieces 201 of the bearing side meshes 200. The fixing is completed by the connecting pins passing through the connecting holes 2011 of the ear pieces 201. At this time, the bearing side meshes 200 and the connecting side meshes 300 together form a closed enclosing space. The top mesh 400 rotates around its hinge point with the connecting side mesh 300 in a direction away from the connecting side mesh 300, and the top mesh 500 rotates synchronously around its hinge point with another connecting side mesh 300 in a direction away from that connecting side mesh 300. When the top mesh panel 400 and the second top mesh panel 500 rotate to the opposite side of the bottom mesh panel 100, the reinforcing bar of the second top mesh panel 500 near the end of the top mesh panel 400 is inserted between the two mounting plates 4010 of the mounting block 401 on the top mesh panel 400, and fasteners are inserted into the mounting holes 4011 of the mounting plates 4010 to connect the top mesh panel 400 and the second top mesh panel 500. At the same time, the reinforcing bar of the bearing side mesh panel 200 near the end of the top mesh panel 400 is inserted between the two mounting plates 5010 of the mounting block 401 on the second top mesh panel 500, and fasteners are inserted into the mounting holes 5011 of the mounting plates 5010 to complete the connection between the second top mesh panel 500 and the bearing side mesh panel 200. At this time, the top mesh panel 400 and the second top mesh panel 500 together seal and surround the top of the space.

[0052] The storage process of this steel cage is as follows: First, remove the fasteners in the first installation hole 4011 and the second installation hole 5011. Rotate the top mesh plate 400 and the second top mesh plate 500 towards the connecting mesh plate 300 and make them fit together. Pull out the connecting pin between the connecting mesh plate 300 and the bearing mesh plate 200. First, rotate the two bearing mesh plates 200 around the first support rod 101 towards the bottom mesh plate 100 until they fit together with the bottom mesh plate 100. Then, rotate the connecting mesh plate 300 around the second support rod 102 towards the bottom mesh plate 100 until it fits together with the bearing mesh plate 200. At this time, the overall structure is compressed into a flat shape, and the abutment plate 301 provides support for the upper steel bars, thus completing the storage.

[0053] In embankment slope reinforcement scenarios, the unfolded steel cage is hoisted to the designated location, and stones or sandbags are filled into the enclosed space. The top mesh seals the area, preventing the filling from being washed away by water flow. The steel cage's structure tightly secures the filling, forming a stable protective structure to resist water erosion at the slope toe. When a breach needs to be sealed, multiple steel cages can be stacked using the support 103 and the limiting plate 1030. The limiting space created by the limiting plate 1030 ensures stacking stability, and the hoisting hole 1031 facilitates rapid hoisting and positioning. The stacked steel cage assembly can quickly fill the breach, using the weight of the internal filling and the structural integrity to block water flow. Combined with other flood control materials, it forms a sealing barrier, quickly controlling the emergency. After the emergency ends, the filling can be removed, and the steel cage can be flattened for easy transportation and storage for future use.

[0054] The overall structure of the reinforcing cage in this example has a high strength tolerance. After being filled with stones, the entire reinforcing cage can be lifted through the lifting hole 1031. The load-bearing mesh 200 and the first support rod 101 are rotatably connected through shaft holes. The lowest horizontal reinforcing bars of the load-bearing mesh 200 are inserted into multiple holes in the first support rod 101. This connection method not only ensures the flexibility of rotation but also allows the load-bearing mesh 200 to be stably stressed under load. The rotatable connection between the connecting mesh 300 and the second support rod 102 is equally reliable. When the two are enclosed to form an enclosed space, the structural stability is greatly improved. After the hooks at the ends of the horizontal reinforcing bars of the connecting mesh 300 and the connecting vertical reinforcing bars are inserted into the limiting space, the multiple sets of lugs 201 on both sides of the load-bearing mesh 200 can firmly fix the ends of the connecting mesh 300, enhancing the strength of the connection and effectively resisting the lateral force generated by the filling of stones. When sealing off the enclosed space, the reinforcing bars of the top mesh 2500 are inserted between the two mounting plates 4010 of the mounting block 401 and fixed with fasteners; the reinforcing bars of the bearing side mesh 200 are also inserted between the two mounting plates 5010 of the mounting block 2501 and fixed with fasteners. This multiple fixing method makes the top and sides form a solid whole. When the reinforcing cage is filled with stones, it is hoisted as a whole through the hoisting holes 1031 on the limiting plate 1030. The force on each component is even, and it can be hoisted smoothly. Even if it rolls during hoisting or transportation, due to the firm and reliable connection parts and the strong overall structural stability, it will not disintegrate and can always maintain its complete shape.
