Description

Technical Field

[0001] This application relates to the technical field of steel cages, and in particular to an adaptive steel cage structure. Background Technology

[0002] In the existing field of diaphragm wall and erosion control wall construction, the reinforcing cage typically adopts an integral long strip skeleton structure, composed of longitudinal main bars, transverse distribution bars, and a certain number of truss members. A certain distance is left between the two rows of reinforcing bars in the cage to allow the guide pipe to enter.

[0003] During the hoisting of the reinforcing cage, deformation or displacement may occur, which in turn affects the smoothness and quality of concrete pouring. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides an adaptive steel cage structure.

[0005] This application provides an adaptive reinforced cage structure, which adopts the following technical solution: An adaptive reinforced cage structure, comprising: Longitudinal main reinforcement bars are distributed in a circular or rectangular array; A transverse distribution bar, wherein one transverse distribution bar is distributed and bound circumferentially along the longitudinal main bar distributed in a ring array, and multiple transverse distribution bars are distributed at intervals along the height direction of the longitudinal main bar, and the transverse distribution bars and the longitudinal main bar form a guide channel; Supporting ribs are installed inside the conduit channel. The two ends of the supporting ribs are detachably connected to the two longitudinal main ribs respectively. The supporting ribs are spaced apart along the height direction of the longitudinal main ribs, and adjacent supporting ribs abut against different longitudinal main ribs.

[0006] By adopting the above technical solution, the supporting ribs form an internal skeleton in the guide tube channel, directly resisting the lateral load during transportation / hoisting, solving the channel deformation and displacement problem in the background technology. Adjacent supporting ribs connect different longitudinal main ribs, dispersing stress to the overall structure, avoiding local stress concentration that leads to torsion. Removing the supporting ribs before pouring does not hinder the lowering of the guide tube, thus balancing the contradictory needs of "transportation protection" and "smooth pouring".

[0007] Optionally, the support rib includes a first support segment and a second support segment that are interlocked with each other. The first support segment and the second support segment are slidably connected to change the length of the support rib. A main locking rod for locking the first support segment and the second support segment is installed on the support rib.

[0008] By adopting the above technical solution, the length of the support bar can be adjusted to adapt to different diameter steel cages or main bar spacing tolerances. Before hoisting, the support bar is stretched to fit the main bar according to the actual spacing, and then the main locking rod is inserted to complete the fastening.

[0009] Optionally, the first support segment is provided with a socket. When the first support segment and the second support segment abut against different longitudinal main bars, the main locking rod is inserted into the socket, and the length of the support bar is locked.

[0010] By adopting the above technical solution, the insertion depth of the main locking rod can intuitively reflect the locking status, reducing the risk of misoperation.

[0011] Optionally, the first support section has a receiving groove in the insertion hole, and a clamping block and a compression spring are installed in the receiving groove of the first support section. The compression spring drives the clamping block to always have a tendency to move towards the second support section. When the main locking rod is inserted into the insertion hole, the clamping block abuts against the main locking rod.

[0012] By adopting the above technical solution, the spring-driven clamping block automatically fits the surface of the main locking rod, compensating for manufacturing tolerances.

[0013] Optionally, the clamping block has an arc-shaped groove.

[0014] By adopting the above technical solution, the arc-shaped groove increases the contact area, making it less likely for the main locking rod to disengage under vibration conditions.

[0015] Optionally, the main locking rod can be simultaneously connected to multiple supporting ribs.

[0016] By adopting the above technical solution, workers continuously insert a main locking rod along the height direction of the steel cage to lock all the supporting bars at different heights in sequence.

[0017] Optionally, the second support segment of one of the supporting ribs is provided with a secondary locking rod, and the second support segment has a sliding groove for the secondary locking rod to move. A positioning rod is connected between the main locking rod and the secondary locking rod. The positioning rod has two sliding grooves, and the main locking rod and the secondary locking rod are respectively located in the two sliding grooves. The positioning rod is provided with a fixing member for fixing the main locking rod and the secondary locking rod.

[0018] By adopting the above technical solution, the sliding groove allows for adjustment of the position of the secondary locking rod, and the secondary locking rod and the main locking rod form a constraint, thereby improving the reliability of the main locking rod.

[0019] Optionally, the fixing component includes a fixing block and a screw rod rotatably connected to the fixing block. The screw rod is threadedly connected to the positioning rod. The fixing block is slidably disposed in the groove for fixing the main locking rod and the auxiliary locking rod.

[0020] By adopting the above technical solution, rotating the screw can press the main locking rod or the auxiliary locking rod.

[0021] Optionally, the second support section has a slot for the first support section to be inserted into, and a limiting block is fixedly connected to the second support section in the slot. The first support section has a limiting groove for the limiting block to slide. A tension spring is installed in the slot. When the main locking rod leaves the support bar, the first support section slides towards the second support section, and the support bar shortens. A push plate is connected to the bottom end of the secondary locking rod. When the secondary locking rod is pulled out of the steel cage, the support bar is pushed out of the steel cage by the push plate.

[0022] By adopting the above technical solution, the cooperation between the limiting block and the limiting groove ensures that the first support section and the second support section cannot be separated from each other. When the main locking rod is unlocked, the support ribs shorten, and the auxiliary locking rod pushes all the support ribs out of the steel cage through the push plate, so that the support ribs can be quickly disassembled.

[0023] In summary, this application includes at least one of the following beneficial effects: 1. By setting support bars in the conduit channel, an internal skeleton is formed to resist the lateral load during transportation and hoisting, and to avoid channel deformation or displacement; adjacent support bars abut against different longitudinal main bars, dispersing stress to the overall structure, preventing the twisting of the steel cage caused by local stress concentration, and the detachable design of the support bars ensures that the conduit is lowered smoothly during pouring, balancing the contradiction between transportation protection and smooth pouring, and ensuring the quality of concrete pouring. 2. The support bars adopt an adjustable length segmented design, which, together with the main locking rod and other components, can adapt to different diameter steel cages or main bar spacing tolerances, and the locking is reliable. Through the simultaneous insertion of multiple support bars by the main locking rod, the reinforcement by the auxiliary locking rod and the positioning rod, and the automatic shortening of the support bars after unlocking and the quick ejection by the push plate, the installation and disassembly operations are simplified, the construction steps are reduced, and the construction efficiency is significantly improved.

Detailed Implementation

[0026] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7 This application will be described in further detail.

[0027] This application discloses an adaptive reinforced steel cage structure. (Refer to...) Figure 1 An adaptive reinforced concrete cage structure mainly includes longitudinal main bars 100 and transverse distribution bars 200, forming an integral skeleton structure for the construction of diaphragm walls and erosion barriers. This structure maintains structural stability during transportation and hoisting while also ensuring unobstructed flow during concrete pouring. The longitudinal main bars 100 consist of multiple bars arranged in a ring or rectangular array, forming the main vertical load-bearing skeleton of the cage. Their number and diameter can be selected according to the project's strength requirements. The transverse distribution bars 200 also consist of multiple bars, fixedly connected to the longitudinal main bars 100 by binding. These transverse distribution bars 200 are spaced apart along the height of the longitudinal main bars 100, with the spacing between adjacent bars determined by the cage's length and stress requirements. These transverse distribution bars 200 cooperate with the longitudinal main bars 100, forming a circular ring of transverse bars on the longitudinal bars. This circular ring encloses a conduit channel 400 inside the cage for lowering the concrete pouring duct. The size of this channel must be compatible with the diameter of the pouring duct to ensure its smooth passage.

[0028] Reference Figure 2 An adaptive steel cage structure also includes support bars 300 installed in the conduit channel 400 to support and reinforce the conduit channel 400, so that the steel cage may deform or shift during transportation or hoisting.

[0029] Reference Figure 3Each support bar 300 is detachably connected to two different longitudinal main bars 100 at both ends, allowing for removal before concrete pouring without affecting the lowering of the duct. A straight line connects the two longitudinal main bars 100 corresponding to each support bar 300, intersecting the central axis of the duct channel 400. The support bars 300 are spaced apart along the height of the longitudinal main bars 100, with the ends of adjacent support bars 300 abutting against different longitudinal main bars 100. This distribution method disperses the supporting force across more longitudinal main bars 100, avoiding localized stress concentration that could cause the steel cage to twist, further enhancing the overall structural stability.

[0030] Reference Figure 3 and Figure 4 The two ends of the support bar 300 abut against the longitudinal main bar 100 respectively. The ends of the support bar 300 are concave in an arc groove structure to increase the contact strength with the longitudinal main bar 100. The support bar 300 consists of a first support section 310 and a second support section 320, which are inserted into each other to achieve a sliding connection. The overall length of the support bar 300 can be changed by relative sliding to adapt to different diameter steel cages or the spacing tolerance between longitudinal main bars 100. In order to fix the support bar 300 after the length is adjusted, a main locking rod 500 is installed on the support bar 300. The surface of the first support section 310 has a through hole 312. When the ends of the first support section 310 and the second support section 320 abut against the corresponding longitudinal main bars 100 respectively, the main locking rod 500 is inserted into the through hole 312 to lock the length of the support bar 300.

[0031] The main locking rod 500 can simultaneously insert multiple support bars 300. That is, along the height direction of the steel cage, one main locking rod 500 passes through the insertion holes 312 of the support bars 300 at different height positions in sequence, and locks multiple support bars 300 at one time, reducing the number of operation steps for workers.

[0032] Reference Figure 5 Within the insertion hole 312 of the first support section 310, a receiving groove 313 is also provided. A clamping block 314 and a compression spring 315 are installed within the receiving groove 313. One end of the compression spring 315 is fixedly connected to the inner wall of the receiving groove 313, and the other end is connected to the clamping block 314. Under the elastic force of the compression spring 315, the clamping block 314 always tends to move towards the second support section 320. When the main locking rod 500 is inserted into the insertion hole 312, the clamping block 314 abuts against the surface of the main locking rod 500 under the action of the spring, automatically compensating for tolerances generated during manufacturing, making the locking more secure. During the insertion of the main locking rod 500 into the insertion hole 312, the clamping block 314 has a guide surface, facilitating the locking rod to press the clamping block 314 and pass through the insertion hole 312.

[0033] The clamping block 314 has an arc-shaped groove at its end, which is adapted to the outer peripheral surface of the main locking rod 500. This increases the contact area between the clamping block 314 and the main locking rod 500. Even under conditions of vibration during transportation or hoisting, the main locking rod 500 is not easy to come out of the insertion hole 312, thus improving the reliability of locking.

[0034] Reference Figure 5 A slot 321 is provided at the corresponding position of the second support section 320. A tension spring 323 is provided between the bottom of the slot 321 and the end face of the first support section 310. When the locking rod is pulled out of the support rib 300, the tension spring 323 drives the first support section 310 to automatically retract.

[0035] Reference Figure 6 A limiting block 322 is fixed inside the slot 321, and a limiting groove 311 that cooperates with the limiting block 322 is opened on the outer wall of the first support section 310 to ensure that the two sections remain coaxial during the sliding process.

[0036] Reference Figure 4 and Figure 5 One of the second support sections 320 is equipped with a secondary locking rod 600, and in this embodiment, the uppermost support rib 300 allows the secondary locking rod 600 to pass through. A sliding groove 324 is provided on the second support section 320 for the secondary locking rod 600 to pass through. This sliding groove 324 allows the secondary locking rod 600 to translate within a certain range along the second support section 320. The translation direction is the same as the length direction of the second support section 320, to accommodate positional changes when the length of the support rib 300 is adjusted.

[0037] Reference Figure 7 A positioning rod 700 connects the main locking rod 500 and the auxiliary locking rod 600. The positioning rod 700 has two sliding grooves 710. The main locking rod 500 and the auxiliary locking rod 600 are located in the two sliding grooves 710 respectively. The positioning rod 700 is also provided with a fixing member 800, which is used to fix the main locking rod 500 and the auxiliary locking rod 600 in a specific position in the sliding groove 710. The auxiliary locking rod 600 and the main locking rod 500 cooperate to form a double constraint, which further improves the stability of the locking state of the support rib 300.

[0038] Reference Figure 7 The fixing component 800 includes a fixing block 810 and a screw 820. One end of the screw 820 is rotatably connected to the fixing block 810, and the other end is threadedly connected to the positioning rod 700. The fixing block 810 is slidably disposed in the slide groove 710. When it is necessary to fix the main locking rod 500 or the auxiliary locking rod 600, the screw 820 is rotated. Under the action of the thread, the screw 820 drives the fixing block 810 to move along the slide groove 710 toward the main locking rod 500 or the auxiliary locking rod 600 until the fixing block 810 abuts against the main locking rod 500 or the auxiliary locking rod 600, thereby achieving the fixation of both. The operation is simple and the fixing effect is reliable.

[0039] When the main locking rod 500 withdraws from the insertion hole 312 of the support rib 300, the tension of the tension spring 323 drives the first support section 310 to slide into the slot 321 of the second support section 320, shortening the overall length of the support rib 300 and facilitating its disassembly. A push plate 610 with a hollow section is connected to the bottom end of the auxiliary locking rod 600 to reduce weight. When the auxiliary locking rod 600 is pulled out of the rebar cage, the push plate 610 moves with it, pushing the support ribs 300 within the guide channel 400 during this movement, pushing all the support ribs 300 out of the rebar cage, achieving rapid disassembly of the support ribs 300 and further improving construction efficiency.

[0040] The implementation principle of an adaptive steel cage structure in this application embodiment is as follows: Support ribs 300 are installed inside the conduit channel 400. The two ends of the support ribs 300 are detachably connected to different longitudinal main ribs 100. They are distributed at intervals along the height direction, and adjacent support ribs 300 abut against different longitudinal main ribs 100 to form an internal skeleton to disperse stress and resist lateral loads, thus preventing channel deformation and displacement. The support ribs 300 adopt a first support section 310 and a second support section 320 that are interlocked with each other. The length can be adjusted by sliding to adapt to different working conditions. They are locked by a main locking rod 500 in conjunction with a clamping block 314 and a compression spring 315, and reinforced by a secondary locking rod 600 and a positioning rod 700. When disassembling, the main locking rod 500 is released and the tension spring 323 shortens the support ribs 300. When the secondary locking rod 600 is pulled out, the push plate 610 pushes out the support ribs 300, thus ensuring the stability of transportation and hoisting without affecting the smoothness of concrete pouring.

[0041] 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.
