Description

Technical Field

[0001] This utility model relates to the field of steel cage technology, and in particular to a double-casing ultra-deep pile foundation steel cage. Background Technology

[0002] The reinforcing cage mainly serves a tensile function. Concrete has high compressive strength but very low tensile strength. The reinforcing cage restrains the concrete of the pile body, enabling it to withstand a certain axial tensile force. During the construction of bridges, culverts, or high-rise buildings, pile driving may be required for the foundation. The method involves using machine punching and water-jet drilling to achieve the design depth. Then, the reinforcing cage is lowered into the pile hole, and a guide pipe is inserted for concrete pouring. Because the foundation pit is relatively deep during the operation, a double-casing ultra-deep pile foundation reinforcing cage is required.

[0003] A search revealed Chinese Patent Publication No. CN214834068U, which discloses an ultra-deep pile foundation reinforcement cage. One side of the steel reinforcement bar is fixedly fitted with an inner fixing ring, and an outer fixing ring is fixedly fitted to the outside of the steel reinforcement bar. A tray is fixedly fitted to the bottom end of the steel reinforcement bar. A reinforcing ring is fixedly fitted to the side of the steel reinforcement bar located at the bottom of the outer fixing ring. A pad is fixedly fitted to the side of the steel reinforcement bar located at the top of the reinforcing ring. A fixing block is fixedly fitted to the bottom of the steel reinforcement bar, and a connecting block is movably fitted to the outside of the fixing block. This utility model overcomes the shortcomings of the prior art by using an outer fixing ring and an inner fixing ring... The rings are used to increase the overall strength of the reinforcing cage, thereby improving the construction quality and preventing the main body of the reinforcing cage from falling apart due to the impact of concrete. By using fixing blocks, connecting blocks, internal threads, and external threads, the reinforcing cage is divided into multiple sections, which facilitates the movement and handling of the reinforcing cage and brings convenience to the construction. However, in actual use, since the straight steel bars are only fixed by the inner and outer fixing rings, the device can only reinforce the middle of the straight steel bars to prevent them from bending from the middle. It cannot fix the position between the straight steel bars, and the fixing rings are difficult to install, requiring temporary welding, which increases the construction time and reduces the practicality of the device. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a double-sleeve ultra-deep pile foundation reinforcement cage, which aims to improve the existing technology that relies solely on inner and outer fixing rings for fixation. This technology can only reinforce the middle of the steel bars to prevent them from bending from the middle, but cannot fix the position of the steel bars. Furthermore, the fixing rings are difficult to install, requiring temporary welding and increasing construction time.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a double-sleeve ultra-deep pile foundation reinforcement cage, comprising a tray, wherein multiple straight steel bars are fixedly connected to the top four sides of the tray, multiple reinforcing bars are fixedly connected to the upper and lower sides of the outer walls of the multiple straight steel bars, multiple inner fixing rings are provided on the inner sides of the multiple straight steel bars, and pipe clamps are fixedly connected to the outer walls of the multiple inner fixing rings, each pipe clamp engaging with the corresponding reinforcing bar. Multiple outer fixing rings are provided on the outer sides of the multiple straight steel bars, and pipe clamps are fixedly connected to the inner walls of the multiple outer fixing rings, each pipe clamp engaging with the corresponding reinforcing bar. Multiple inner fixing seats are fixedly connected to the outer walls of the multiple inner fixing rings, and outer fixing seats are fixedly connected to the outer walls of the multiple outer fixing rings. Bolts are threadedly connected to the outer sides of the multiple outer fixing seats, and the multiple outer fixing seats are threadedly connected to the inner fixing seats through the bolts. Multiple reinforcing bars are fixedly connected between adjacent outer fixing rings, and a quick-installation mechanism is provided at one adjacent end of the multiple outer fixing rings.

[0006] Through the above technical solution: the tray, as the basic load-bearing component, provides a stable support platform for the entire reinforcing cage. Multiple straight steel bars are the main vertical load-bearing components of the reinforcing cage, bearing the axial force and bending moment during the construction and use of the pile foundation. The reinforcing bars are tightly connected to the straight steel bars, forming a stable frame structure, enhancing the straight steel bars' resistance to lateral deformation, and preventing them from bending and becoming unstable under complex stress conditions. The inner and outer fixing rings are positioned by engaging with the reinforcing bars through pipe clamps one and two, respectively, ensuring that the ring bars are evenly distributed and stably fixed in the circumferential direction of the reinforcing cage. The inner and outer fixing seats are connected by bolt threads, further strengthening the tight connection between the inner fixing ring 5 and the outer fixing ring 6, and improving the circumferential load-bearing capacity of the reinforcing cage. When the reinforcing cage is subjected to external forces, the reinforcing bars quickly disperse and transfer the stress to the surrounding structural components, avoiding stress concentration that could lead to local damage.

[0007] As a further description of the above technical solution:

[0008] The quick-installation mechanism includes a first installation plate, which is fixedly connected to the top of multiple steel ribs. A second installation plate is provided on the top of the first installation plate. Insert plates are fixedly connected to the bottom four sides of the second installation plate. Installation grooves are opened on the top four sides of the first installation plate. Multiple insert plates are engaged with the corresponding installation grooves. Multiple reserved grooves are opened on the inner walls of the first installation plate. Multiple springs are fixedly connected to the inner walls of the multiple reserved grooves. A locking block is fixedly connected to the adjacent end of each of the multiple springs. Locking slots are opened on the outer walls of the multiple second installation plates. Multiple locking blocks are engaged with the corresponding locking slots.

[0009] Through the above technical solution: Installation plate two is used to fix the upper steel reinforcement bars. The bottom insert plate of installation plate two cooperates with the top mounting groove of installation plate one to achieve initial positioning, ensuring that installation plate two is quickly and accurately placed on top of installation plate one, laying the foundation for subsequent connection. During the insertion of installation plate two, the clamping block is squeezed first. After the clamping block is squeezed, the spring is compressed and slides into the reserved groove. At this time, the spring stores elastic potential energy. When installation plate two is fully inserted into installation plate one, the groove on installation plate two corresponds to the reserved groove, and the spring releases elastic potential energy to squeeze the clamping block, so that the clamping block is locked into the groove, thereby fixing installation plate two in the horizontal direction. Anti-corrosion layer one and anti-corrosion layer two can effectively isolate external corrosive media, greatly extend the service life of the tray and installation plate two, and ensure the long-term stable performance of the rebar cage. Indicating arrow one and indicating arrow two provide precise visual guidance for installation. Operators align the insert plate with the mounting groove and the clamping block with the groove according to the arrow indication, simplifying the installation process and improving the operation accuracy.

[0010] As a further description of the above technical solution:

[0011] The inner wall of the inner fixing ring is fixedly connected with multiple protrusions at equal intervals around its perimeter. Multiple grooves are provided between adjacent protrusions, and the multiple grooves are equally spaced around the inner wall of the inner fixing ring.

[0012] The above technical solution uses protrusions and grooves to make the inner surface of the inner fixing ring uneven, increasing the friction between the inner fixing ring and the concrete, thus ensuring a tight connection between the concrete and the device.

[0013] As a further description of the above technical solution:

[0014] The diameter of each of the reinforcing bars is smaller than the diameter of the straight steel bar, and the distance between the reinforcing bars is equal.

[0015] The above technical solution enables uniformly distributed reinforcing bars to evenly constrain the deformation of straight steel bars and prevent local instability.

[0016] As a further description of the above technical solution:

[0017] An information board is provided on the front side of the outer wall of the tray. Screws are threaded around the outer wall of the information board, and the information board is threaded to the tray through the screws.

[0018] The above technical solution allows information boards to be used to engrave project identification, rebar cage specifications, production date, and batch number, providing clear guidance for the entire construction process management.

[0019] As a further description of the above technical solution:

[0020] The outer wall of the middle outer fixing ring is fixedly connected to the left and right sides of the outer wall, and the middle of the two fixing blocks is provided with a reserved hole.

[0021] The above technical solution involves fixing the positioning rope through a pre-drilled hole during the hoisting of the reinforcing cage into the pile hole. This helps to accurately control the verticality and planar position of the reinforcing cage, ensuring that the deviation from the center of the pile hole is within the allowable range and guaranteeing the positioning accuracy of the pile foundation.

[0022] As a further description of the above technical solution:

[0023] The outer wall of the second mounting plate is fixedly connected with an anti-corrosion layer one, and the outer wall of the first mounting plate is fixedly connected with an anti-corrosion layer two.

[0024] Through the above technical solutions, the first and second anti-corrosion layers can effectively isolate external corrosive media, significantly extending the service life of the pallet and the second mounting plate.

[0025] As a further description of the above technical solution:

[0026] An indicator arrow is fixedly connected to the front side of the outer wall of the second mounting plate, and an indicator arrow is fixedly connected to the front side of the outer wall of the first mounting plate.

[0027] The above technical solution provides precise visual guidance for installation by using arrow 1 and arrow 2. Operators can align the insert plate with the mounting slot and the clip with the slot according to the arrow indication, which simplifies the installation process and improves the accuracy of operation.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the reinforcing bars are tightly connected to the straight steel bars, which enhances the straight steel bars' resistance to lateral deformation. The inner and outer fixing rings are positioned by engaging with the reinforcing bars through pipe clamps one and two, respectively, ensuring that the reinforcing bars are evenly distributed and stably fixed in the circumferential direction of the steel cage. The inner and outer fixing seats are connected by bolt threads, which further strengthens the tight connection between the inner and outer fixing rings. After the bolts are tightened, the inner and outer fixing rings work together to increase the circumferential bearing capacity of the steel cage, thereby preventing the straight steel bars from bending and facilitating installation.

[0030] 2. In this utility model, the insertion plate is initially positioned by cooperating with the top mounting groove of the first mounting plate to prevent the second mounting plate from rotating. During the insertion of the second mounting plate, the locking block is first squeezed, thereby compressing the spring and sliding into the reserved groove. When the second mounting plate is fully inserted into the first mounting plate, the locking groove on the second mounting plate corresponds to the reserved groove. The spring releases its elastic potential energy to squeeze the locking block, causing the locking block to lock into the locking groove. This fixes the second mounting plate in the vertical direction, preventing the second mounting plate from moving up and down. This ensures the stability of the entire device while enabling quick installation and reducing installation difficulty. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a double-casing ultra-deep pile foundation reinforcement cage, including a tray 1. The tray 1 serves as the foundation component of the entire reinforcement cage structure, and its main function is to provide a stable and horizontal bearing platform for the various structural components constructed above. Multiple steel bars 3 are fixedly connected to the top four sides of the tray 1. During construction, such as hoisting and lowering the reinforcement cage, and the subsequent concrete pouring, the additional vertical forces generated are transmitted by the steel bars 3 to the tray 1, and then distributed by the tray 1 to the foundation soil at the pile bottom. Multiple reinforcing bars 4 are fixedly connected to the upper and lower sides of the outer walls of the multiple steel bars 3. The reinforcing bars 4 provide lateral support and constraint for the steel bars 3. Multiple inner fixing rings 5 ​​are provided on the inner sides of the multiple steel bars 3. Inside the steel reinforcement bars 3, they serve as auxiliary positioning and enhance the overall structural integrity within the reinforcing cage. Multiple inner fixing rings 5 ​​are secured with pipe clamps 7 around their outer walls, each clamp engaging with a corresponding reinforcing bar 4. The inner fixing rings 5 ​​are precisely fixed within the frame structure constructed from the steel reinforcement bars 3 and 4, ensuring their exact circumferential position and preventing rotation or displacement. Multiple outer fixing rings 6 are located on the outer sides of the steel reinforcement bars 3. Each outer fixing ring 6 is secured with pipe clamps 8 around its inner walls, each clamp engaging with a corresponding reinforcing bar 4. The outer fixing rings 6 achieve precise circumferential positioning, ensuring stable fixation within the frame structure formed by the steel reinforcement bars 3 and 4. In terms of frame structure, to prevent unnecessary displacement or rotation of the outer fixing ring 6 during construction, multiple inner fixing seats 9 are fixedly connected to the outer walls of multiple inner fixing rings 5, and multiple outer fixing seats 10 are fixedly connected to the outer walls of multiple outer fixing rings 6. Bolts 11 are threadedly connected to the outer sides of multiple outer fixing seats 10, and multiple outer fixing seats 10 are threadedly connected to the inner fixing seats 9 through bolts 11. The threaded connection between the outer fixing seats 10 and the inner fixing seats 9 through bolts 11 makes the inner fixing rings 5 ​​and outer fixing rings 6 an organic whole structure. Multiple reinforcing ribs 12 are fixedly connected between adjacent outer fixing rings 6. During hoisting, when the steel cage is subjected to external forces such as wind force and uneven tension of the hoisting ropes, the reinforcing ribs 12 can distribute the stress generated by these external forces. The reinforcement cage is spread out to better withstand external forces. A quick-installation mechanism 2 is provided at one adjacent end of each of the multiple outer fixing rings 6. The diameters of the multiple reinforcing bars 4 are all smaller than the diameters of the straight steel bars 3, and the distances between the multiple reinforcing bars 4 are equal. The straight steel bars 3 mainly bear the larger vertical loads, while the reinforcing bars 4 focus on providing lateral support. The smaller diameter satisfies the functional requirement of laterally restraining the straight steel bars 3 without excessively increasing the overall structure's self-weight and material usage. Fixing blocks 17 are fixedly connected to the left and right sides of the outer wall of the central outer fixing ring 6. Pre-drilled holes 18 are provided in the middle of each of the two fixing blocks 17. During the hoisting of the reinforcement cage, the pre-drilled holes 18 on the fixing blocks 17 can be used to connect hoisting ropes or lifting devices, facilitating the hoisting operation of the reinforcement cage.

[0040] Specifically, tray 1 serves as the basic load-bearing component, providing a stable support platform for the entire reinforcing cage. Multiple straight steel bars 3 are the main vertical load-bearing components of the reinforcing cage, bearing the axial force and bending moment during pile foundation construction and use. Reinforcing bars 4 are tightly connected to the straight steel bars 3, forming a stable frame structure, enhancing the straight steel bars 3's resistance to lateral deformation, and preventing them from bending and becoming unstable under complex stress conditions. Inner fixing ring 5 and outer fixing ring 6 are positioned by engaging with reinforcing bars 4 through pipe clamps 1 and 2 (pipe clamps 8), ensuring that the ring bars are evenly distributed and stably fixed in the circumferential direction of the reinforcing cage. Inner fixing seat 9 and outer fixing seat 10 are threadedly connected by bolts 11, further strengthening... The inner fixing ring 5 and the outer fixing ring 6 are tightly connected. After the bolt 11 is tightened, the inner fixing ring 5 and the outer fixing ring 6 work together to enhance the circumferential bearing capacity of the steel cage. When the steel cage is subjected to external forces, the reinforcing rib 12 quickly disperses and transfers the stress to the surrounding structural components, avoiding stress concentration that could lead to local damage. Under the lateral pressure during concrete pouring, the evenly distributed reinforcing rib 4 can evenly constrain the deformation of the straight steel rib 3, preventing local instability. During the process of hoisting the steel cage into the pile hole, the positioning rope is fixed through the reserved hole 18 to help accurately control the verticality and planar position of the steel cage, ensuring that the deviation from the center of the pile hole is within the allowable range and guaranteeing the positioning accuracy of the pile foundation.

[0041] Reference Figure 4 and Figure 5The quick-installation mechanism 2 includes a first mounting plate 201, which is fixedly connected to the top of multiple steel ribs 3. The first mounting plate 201 provides basic support for the entire quick-installation mechanism 2. A second mounting plate 202 is provided on the top of the first mounting plate 201. Insert plates 203 are fixedly connected to the bottom four sides of the second mounting plate 202. Mounting grooves 204 are opened on the top four sides of the first mounting plate 201. The multiple insert plates 203 engage with the corresponding mounting grooves 204. The insert plates 203 on the bottom four sides of the second mounting plate 202 cooperate with the mounting grooves 204 on the top four sides of the first mounting plate 201 to achieve initial positioning and prevent the second mounting plate 202 from rotating. Multiple reserved grooves 205 are opened on the inner wall of the first mounting plate 201. The reserved grooves 205 provide installation space for other components. Multiple springs 206 are fixedly connected to the inner wall of the multiple reserved grooves 205. A locking block 207 is fixedly connected to the adjacent end of the multiple springs 206. The continuous elastic force of the spring 206 ensures that the locking block 207 is tightly locked in the slot 208, forming a stable locking connection. The outer walls of multiple mounting plates 202 are all provided with slots 208, and multiple locking blocks 207 are locked into the corresponding slots 208. The outer wall of the mounting plate 202 is fixedly connected with anti-corrosion layer 19, and the outer wall of the mounting plate 101 is fixedly connected with anti-corrosion layer 20. Anti-corrosion layer 19 and anti-corrosion layer 20 can effectively isolate external corrosive media, greatly extend the service life of the quick-installation mechanism 2, and ensure the long-term stable performance of the steel cage. The front side of the outer wall of the mounting plate 202 is fixedly connected with indicator arrow 121, and the front side of the outer wall of the mounting plate 101 is fixedly connected with indicator arrow 22. Indicator arrow 121 and indicator arrow 22 provide precise visual guidance for installation. The operator aligns the insert plate 203 with the mounting slot 204 and the locking block 207 with the slot 208 according to the arrow indication, simplifying the installation process and improving the operation accuracy.

[0042] Specifically, mounting plate 202 is used to fix the upper steel rib 3. The bottom insert plate 203 of mounting plate 202 cooperates with the top mounting groove 204 of mounting plate 1 201 to achieve initial positioning, ensuring that mounting plate 202 is quickly and accurately placed above mounting plate 1 201, laying the foundation for subsequent connection. During the insertion of mounting plate 202, the clamping block 207 is first squeezed. After the clamping block 207 is squeezed, the compression spring 206 slides into the reserved groove 205. At this time, the spring 206 stores elastic potential energy. When mounting plate 202 is fully inserted into mounting plate 1 201, the groove 208 on mounting plate 202 and the clamping block 208 on mounting plate 202... After the reserved slot 205 is aligned, the spring 206 releases its elastic potential energy to squeeze the locking block 207, causing the locking block 207 to engage in the slot 208, thereby fixing the second mounting plate 202 in the horizontal direction. The first anti-corrosion layer 19 and the second anti-corrosion layer 20 can effectively isolate external corrosive media, greatly extending the service life of the tray 1 and the second mounting plate 202, and ensuring the long-term stable performance of the steel cage. The first indicator arrow 21 and the second indicator arrow 22 provide precise visual guidance for installation. The operator aligns the insert plate 203 with the mounting slot 204 and the locking block 207 with the slot 208 according to the arrow indication, simplifying the installation process and improving the operation accuracy.

[0043] Reference Figure 1 , Figure 2 and Figure 4 Multiple protrusions 13 are equidistantly fixed to the inner wall of the inner fixing ring 5. Multiple grooves 14 are provided between adjacent protrusions 13. The multiple grooves 14 are equidistantly opened on the inner wall of the inner fixing ring 5. The protrusions 13 and grooves 14 make the inner surface of the inner fixing ring 5 uneven, increasing the friction between the inner fixing ring 5 and the concrete, so that the concrete is tightly connected to the device. An information plate 15 is provided on the front side of the outer wall of the tray 1. Screws 16 are threaded to the outer wall of the information plate 15. The information plate 15 is threaded to the tray 1 through the screws 16. The information plate 15 is used to engrave the project identification, steel cage specifications, production date and batch number, providing clear guidance for the management of the entire construction process.

[0044] Specifically, the protrusions 13 and grooves 14 make the inner surface of the inner fixing ring 5 uneven, increasing the friction between the inner fixing ring 5 and the concrete, so that the concrete is tightly connected to the device; the information plate 15 is used to engrave the project identification, steel cage specifications, production date and batch number, providing clear guidance for the management of the entire construction process.

[0045] Working Principle: Before using the device, the tray 1 is first fixed inside the foundation pit. Multiple straight steel bars 3 are the main vertical load-bearing components of the reinforcing cage, bearing the axial force and bending moment during pile foundation construction and use. The reinforcing bars 4 are tightly connected to the straight steel bars 3, forming a stable frame structure, enhancing the lateral deformation resistance of the straight steel bars 3, and preventing them from bending and becoming unstable under complex stress conditions. The inner fixing ring 5 and the outer fixing ring 6 are positioned by engaging with the reinforcing bars 4 through pipe clamps 1 and 2, respectively, ensuring that the ring bars are evenly distributed and stably fixed in the circumferential direction of the reinforcing cage. The inner fixing seat 9 and the outer fixing seat 10 are threadedly connected by bolts 11, further strengthening the tight connection between the inner fixing ring 5 and the outer fixing ring 6. After the bolts 11 are tightened, the inner fixing ring 5 and the outer fixing ring 6 work together to increase the circumferential bearing capacity of the reinforcing cage. When the reinforcing cage is subjected to external forces, the reinforcing bars 12 quickly disperse and transfer the stress to the surrounding structure. The structural components prevent stress concentration from causing localized damage. Under the lateral pressure during concrete pouring, the evenly distributed reinforcing bars 4 can evenly constrain the deformation of the straight steel bars 3, preventing local instability. Furthermore, the initial positioning is achieved by cooperating the bottom insert plate 203 of the second mounting plate 202 with the top mounting groove 204 of the first mounting plate 201. During the insertion of the second mounting plate 202, the locking block 207 is first squeezed. After the locking block 207 is squeezed, the spring 206 slides into the reserved groove 205. At this time, the spring 206 stores elastic potential energy. When the second mounting plate 202 is fully inserted into the first mounting plate 201, the groove 208 on the second mounting plate 202 corresponds to the reserved groove 205. The spring 206 releases its elastic potential energy to squeeze the locking block 207, causing the locking block 207 to be locked into the groove 208, thereby fixing the second mounting plate 202 in the vertical direction and preventing the second mounting plate 202 from moving up and down.
