Description

A rebar cage deviation control device and its thickness control method Technical Field

[0001] This invention relates to the technical field of rebar cage misalignment devices, and more specifically, to a rebar cage misalignment control device and its thickness control method. Background Technology

[0002] Reinforcing cage misalignment refers to a construction quality problem in the construction of reinforced concrete structures for pile foundations (such as bored piles) where the actual installation position of the reinforcing cage deviates from the predetermined design position. The deviation is mainly reflected in two core dimensions: spatial position and protective layer thickness. Specifically, it can be divided into horizontal position offset and verticality deviation. Due to the horizontal offset and verticality deviation of the reinforcing cage, the distance between the outer side of the reinforcing bar and the steel casing inside the hole (i.e., the protective layer thickness) exceeds the allowable range of the design and specifications, which manifests as a local protective layer that is too thin (below the design value) or too thick (far greater than the design value).

[0003] The thickness of the protective layer is crucial for the corrosion and carbonation prevention of reinforced concrete structures. If the reinforcement cage is misaligned, resulting in an excessively thin protective layer, the reinforcement will be susceptible to environmental erosion and corrosion, reducing the service life of the structure. If the protective layer is too thick, it will weaken the effective cross-section of the component and affect its load-bearing capacity.

[0004] Existing technology uses limiting clamps installed on the inner wall of the steel casing to limit the movement of the rebar cage during lowering. The existing limiting clamps mainly consist of multiple sets of circumferentially arranged clamps and fixtures. The clamps position the clamps on the inner wall of the steel casing. When the rebar cage is lowered, it slides down close to the clamps. Since the position of the clamps is fixed, when the rebar cage deviates to a certain point during lowering, the friction between the clamp and the rebar cage at that point increases. This causes the clamp to expand and deform due to friction and heat, or to wear out and become concave, thus affecting the limiting accuracy. Summary of the Invention

[0005] The present invention provides a rebar cage offset control device and its thickness control method. The problem to be solved is that in the existing rebar cage offset control device, when the rebar cage is tilted to a certain place during the lowering process, the fixed position of the locking block will increase the friction between the locking block and the rebar cage at that place, causing the locking block to expand and deform due to friction and heat, or to be worn out and dented, thereby affecting the limiting accuracy.

[0015] The present invention also provides a thickness control method for a rebar cage misalignment control device, comprising the following steps:

[0016] S1: The outer limit seat is assembled on the top edge of the steel casing through the slot, and the bolts are used for positioning. Then the steel cage is inserted from the inside of the inner limit seat.

[0017] S2: By inserting the insert plate into the insert plate slot, the push plate is pushed to move laterally, causing the abutment plate to move out of the slot, so that the arc-shaped protrusion protrudes to the inner wall of the inner limit seat and contacts the steel cage for limit.

[0018] S3: The inner limit seat rotates relative to the outer limit seat through gear and tooth groove transmission, thereby driving the abutment plate to rotate. The arc-shaped protrusion abuts against the surface of the steel cage, so that the abutment plate contacts different parts of the steel cage.

[0019] S4: Add lubricating oil into the input seat through the oil hole at the top of the input seat, and then add lubricating oil into the transverse groove through the input port. After running for a period of time, close the valve and extract the high-temperature lubricating oil through the extraction port and the oil filling port. After the high-temperature lubricating oil extracted through the extraction seat is cooled, open the valve and replenish the lubricating oil into the input seat through the connecting pipe.

[0020] The beneficial effects of this invention are as follows:

[0021] This invention, by rotating the inner limiting seat, can support the tilted rebar cage if it becomes skewed during the lowering process. This avoids continuous contact and friction between the same part of the abutment plate and the skewed part of the lowered rebar cage, effectively preventing the abutment plate from expanding and deforming due to friction and heating, or from becoming dented due to excessive wear, thereby ensuring the limiting accuracy of the abutment plate.

[0022] This invention drives a gear to rotate via a driver, and the gear and tooth groove transmit power, causing the inner limit seat to rotate relative to the outer limit seat, thereby driving the abutment plate to rotate. The arc-shaped protrusion abuts against the surface of the reinforcing cage. The cooling channel is filled with coolant to facilitate the cooling of the arc-shaped protrusion.

[0023] This invention adds lubricating oil into the input seat through the oil hole at the top of the input seat, and then adds lubricating oil into the transverse groove through the input port. After running for a period of time, the valve is closed, and the high-temperature lubricating oil is extracted through the extraction port and the oil filling port. At this time, the input seat continues to add lubricating oil into the transverse groove. After the high-temperature lubricating oil extracted by the extraction seat is cooled, the valve is opened, and the lubricating oil is replenished into the input seat through the connecting pipe. By setting the extraction seat and the input seat, it is convenient to add lubricating oil in a cyclical manner, which effectively avoids the outer limit seat and the inner limit seat from deforming and getting stuck due to excessive temperature.

[0024] This invention inserts a plate into the slot, which pushes the push plate to move laterally. This, in turn, moves the abutment plate outward through the push block, causing the arc-shaped protrusion to protrude to the inner wall of the inner limiting seat so as to contact the reinforcing cage for limiting. During disassembly, the plate is pulled out to leave space for the abutment plate to move laterally. Then, the outer and inner limiting seats are removed from the steel casing, avoiding the influence of friction between the arc-shaped protrusion and the reinforcing cage during disassembly.

[0042] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0043] Example 1

[0044] Referring to Figures 1 to 5 of the specification, a rebar cage offset control device includes a steel casing 9, on which a rotating support device is installed. The rotating support device is a first adjustment mechanism, which includes an adjusting outer limit seat 1. An inner limit seat 2 is slidably provided on the inner side of the outer limit seat 1. A driving component 3 is installed on the outer limit seat 1, and the driving component 3 drives the inner limit seat 2 to rotate. An abutment plate 4 is installed on the inner wall of the inner limit seat 2. A slot 11 is opened on the outer side of the outer limit seat 1, and a sliding groove 12 is opened on the inner side of the outer limit seat 1. A vertical groove 21 is opened on the outer side of the inner limit seat 2, and a slot 23 is opened on the inner side of the inner limit seat 2. The outer limit seat 1 is assembled on the steel casing 9 through the slot 11. The portion of the inner limit seat 2 corresponding to the vertical groove 21 is slidably connected to the sliding groove 12. The abutment plate 4 is installed inside the slot 23 and slides in contact with the rebar cage 8.

[0045] It should be noted that the slot 11 is a vertical slot, the sliding slot 12 is an L-shaped slot, the inner limit seat 2 is an L-shaped component corresponding to the vertical slot 21, the L-shaped component and the L-shaped slot are interference fit, and the abutment plate 4 is laterally slidably set inside the slot 23.

[0046] In this embodiment, the specific implementation scenario is as follows: the outer limiting seat 1 and the inner limiting seat 2 are assembled as a whole during production. First, the outer limiting seat 1 is assembled on the top edge of the steel casing 9 through the slot 11 and positioned using bolts. Then, the reinforcing cage 8 is inserted from inside the inner limiting seat 2. When the reinforcing cage 8 deviates during its lowering process, it is limited by the abutment plate 4. The inner limiting seat 2 is rotated relative to the outer limiting seat 1 by the drive component 3, so that the rotating abutment plate 4 contacts the deviated position of the reinforcing cage 8. The inner limiting seat 2 is set by rotation, so that when the reinforcing cage 8 deviates during its lowering process, the rotating abutment plate 4 can support the deviated reinforcing cage 8, avoiding continuous contact and friction between the same part of the abutment plate 4 and the deviated position of the lowered reinforcing cage 8. This effectively prevents the abutment plate 4 from expanding and deforming due to friction and heating, or from becoming dented due to excessive wear, thereby ensuring the limiting accuracy of the abutment plate 4.

[0047] Referring to Figures 5 and 6 in the specification, the drive assembly 3 includes a drive base 31, a driver 32 is installed inside the drive base 31, a gear 33 is connected to the output end of the driver 32, and a toothed groove 26 is provided on the outer side of the inner limit seat 2, and the gear 33 meshes with the toothed groove 26.

[0048] It should be noted that the meshing part of the gear 33 is located outside the drive seat 31, the inner wall of the tooth groove 26 is provided with a rack, the driver 32 adopts a servo motor, and through the meshing of the gear 33 and the tooth groove 26, the servo motor drives the inner limit seat 2 to rotate relative to the outer limit seat 1.

[0049] Referring to Figure 6 in the instruction manual, the drive base 31 has a control mounting slot 34 and an electrical mounting slot 35 inside, and the control mounting slot 34 and the electrical mounting slot 35 are staggered. A cover plate 36 is detachably installed on the top of the drive base 31.

[0050] It should be noted that the control mounting slot 34 is used to install the control terminal, the electrical mounting slot 35 is used to install electrical components such as power supplies, and the cover plate 36 is removable for easy maintenance.

[0051] Referring to Figure 7 in the instruction manual, an arc-shaped protrusion 41 is fixedly provided on the inner side of the abutment plate 4, and a cooling channel 42 is provided inside the abutment plate 4 at the position corresponding to the arc-shaped protrusion 41.

[0052] It should be noted that the arc-shaped protrusion 41 is an arc-shaped annular component, the cooling channel 42 is filled with coolant, and one end of the cooling channel 42 is sealed by a removable plug.

[0053] In this embodiment, the specific implementation scenario is as follows: the driver 32 drives the gear 33 to rotate, and the gear 33 transmits power to the tooth groove 26, causing the inner limit seat 2 to rotate relative to the outer limit seat 1, thereby driving the abutment plate 4 to rotate, and the arc-shaped protrusion 41 abuts against the surface of the steel cage 8. The cooling channel 42 is filled with coolant to facilitate the cooling of the arc-shaped protrusion 41.

[0054] The rotational connection between the outer limit seat 1 and the inner limit seat 2 can easily lead to friction and heat generation. Excessive temperature can cause deformation and result in rotational jamming.

[0055] Referring to Figure 8 in the specification, in order to solve this problem, the following technical solution is also provided: an extraction seat 5 is installed on the outer limit seat 1, and input seats 6 are connected to both ends of the extraction seat 5. The input seats 6 are installed above the outer limit seat 1, and a connecting pipe 62 is connected between the extraction seat 5 and the input seats 6.

[0056] It should be noted that the top of the input seat 6 is provided with an oil hole, and the connecting pipe 62 is connected to the end of the input seat 6. The input seat 6 delivers lubricating oil between the outer limit seat 1 and the inner limit seat 2. The overheated lubricating oil is extracted by the extraction seat 5, cooled, and then delivered to the input seat 6 for circulation.

[0057] Referring to Figures 4 and 5 in the instruction manual, a lubrication port 13 is provided on the top of the outer limiting seat 1, and a transverse groove 22 is provided on the outer side of the inner limiting seat 2, and the transverse groove 22 is connected to the lubrication port 13.

[0058] It should be noted that lubricating oil is added to the transverse groove 22 through the lubrication port 13. The transverse groove 22 corresponds to the connection gap between the outer limit seat 1 and the inner limit seat 2.

[0059] Referring to Figure 8 in the instruction manual, the bottom of the extraction seat 5 is provided with an extraction port 51, the outside of the extraction seat 5 is fixedly provided with an oil inlet 52, both ends of the extraction seat 5 are equipped with valves 53, and the bottom of the input seat 6 is provided with an input port 61.

[0060] It should be noted that the extraction port 51 is connected to the oil filling port 52, the valve 53 can be a solenoid valve, and several sets of lubrication ports 13 are set corresponding to the extraction port 51 and the input port 61. The extraction port 51 and the input port 61 are respectively connected to the corresponding lubrication ports 13.

[0061] In this embodiment, the specific implementation scenario is as follows: lubricating oil is added into the input seat 6 through the oil hole at the top of the input seat 6, and then lubricating oil is added into the transverse groove 22 through the input port 61. After running for a period of time, the valve 53 is closed, and the high-temperature lubricating oil is extracted through the extraction port 51 and the oil filling port 52. At this time, the input seat 6 continues to add lubricating oil into the transverse groove 22. After the high-temperature lubricating oil extracted by the extraction seat 5 is cooled, the valve 53 is opened, and the lubricating oil is replenished into the input seat 6 through the connecting pipe 62. By setting the extraction seat 5 and the input seat 6, it is convenient to add lubricating oil in a cyclical manner, which effectively avoids the outer limit seat 1 and the inner limit seat 2 from deforming and becoming stuck due to excessive temperature.

[0062] Referring to Figures 1 and 9 in the instruction manual, an adjustment component 7 is movably provided on the inner limit seat 2. The adjustment component 7 includes a plate 71. A fixing piece 72 is fixedly provided at the bottom of the plate 71, and the fixing piece 72 is positioned with the inner limit seat 2 by screws. A plate slot 24 is provided at the top of the inner limit seat 2, and the plate 71 passes through the inside of the plate slot 24.

[0063] It should be noted that when the insert plate 71 is inserted into the insert plate slot 24, the abutment plate 4 can be pushed outward toward the slot 23.

[0064] Referring to Figure 9 in the instruction manual, a push plate 73 is movably provided on one side of the insert plate 71, and a push block 74 is fixedly provided on one side of the push plate 73. A push plate groove 25 is opened on the inner side of the inner limiting seat 2, and the push plate groove 25 is connected to the slot 23 and the insert plate groove 24 respectively.

[0065] It should be noted that the push block 74 can be fixedly or movably connected to the abutment plate 4, and the push plate 73 slides laterally inside the push plate groove 25.

[0066] In this embodiment, the specific implementation scenario is as follows: inserting the insert plate 71 into the insert plate slot 24 can push the push plate 73 to move laterally, thereby causing the abutment plate 4 to move outward from the slot 23 through the push block 74, so that the arc-shaped protrusion 41 protrudes to the inner wall of the inner limit seat 2, so as to contact the steel cage 8 for limiting. During disassembly, by pulling out the insert plate 71, space is left for the abutment plate 4 to move laterally, and then the outer limit seat 1 and the inner limit seat 2 are removed from the steel casing 9 to avoid the influence of the contact friction between the arc-shaped protrusion 41 and the steel cage 8 during disassembly.

[0067] The first control mechanism is suitable for the installation of the reinforcing cage 8 of medium and shallow bored piles. Since the reinforcing cage 8 is relatively short, it is only necessary to control the offset and thickness at the position near the upper layer to ensure that the reinforcing cage 8 will not be offset during installation.

[0072] It should be noted that the bottom rib 81 is a ring-shaped component without protrusions. The horizontal plate 120 can slide laterally along the L-shaped groove 1021. The horizontal plate 120 is positioned on the L-shaped groove 1021 by screws through the positioning plate 1023 and the positioning groove 1022. The spring 135 keeps the limiting plate 134 away from the horizontal plate 120 in its natural state.

[0073] Referring to Figures 11 and 12 in the instruction manual, the outer periphery of the steel casing 9 is provided with calibration ear tubes 91, and several sets of calibration ear tubes 91 are arranged around the outer periphery of the steel casing 9. The outer periphery of the steel casing 9 is provided with fixed ear plates 92, and telescopic ear plates 93 are slidably provided on the fixed ear plates 92.

[0074] It should be noted that the steel casing 9 is calibrated by using a distance measuring tool through the calibration ear tube 91 so that the steel casing 9 coincides with the central axis of the pile hole. Fixing holes are provided on both the fixed ear plate 92 and the telescopic ear plate 93, and the fixed ear plate 92 and the telescopic ear plate 93 are fixed to the ground through the fixing holes.

[0075] In this embodiment, the specific implementation scenario is as follows: The steel casing 9 is calibrated by using a ranging tool to align the calibration earpiece 91, ensuring that the steel casing 9 coincides with the central axis of the pile hole. Subsequently, using the steel casing 9 as a reference, after calibration, the fixing ear plate 92 and the telescopic ear plate 93 are fixed to the ground through the fixing holes, and the steel casing 9 is positioned and installed. Similar to Embodiment 1, the reinforcing cage 8 is installed inside the steel casing 9. At this time, the radial limit control of the reinforcing cage 8 is performed through the guide shaft 103. When the reinforcing cage 8 is tilted, the pressure between the movable seat 101 and the steel casing 9 will be reduced. When the force or tilt angle changes, the monitoring sensor 106 detects the pressure or tilt angle change between the movable seat 101 and the steel casing 9 through the monitoring port 109. The connecting ring 104 is detachably connected to one end of the movable seat 101 by screws. The transmission ring 105 is connected to the drive assembly 110 through belt or gear meshing. The drive assembly 110 controls the movable seat 101 to slide along the upper edge of the steel casing 9, so that the guide shaft 103 and the reinforcing cage 8 make relative sliding contact. Different guide shafts 103 make contact with the reinforcing cage 8 at different skew points to avoid... Continuous friction occurs between the guide shaft 103 and the reinforcing cage 8. When the bottom reinforcing bar 81 without protrusion abuts against the support block 130, it will drive the support block 130 to descend synchronously. At this time, the limiting plate 134 approaches the horizontal plate 120, and the spring 135 is compressed until the support block 130 descends to the lowest point, supporting the reinforcing cage 8 to descend halfway. The descent of the reinforcing cage 8 is then stopped. The support shaft 132 can then rotate to support the reinforcing cage 8, and the movable seat 101 can slide circumferentially. This releases the locking of the positioning plate 1023 to the horizontal plate 120, allowing it to move away from the reinforcing cage 8. The horizontal plate 120 allows the support block 130 to detach from the bottom reinforcement 81, and then the steel cage 8 continues to be lowered until it is fully in place. By retracting the support column 102 away from the steel cage 8, it is easy to disassemble the entire second control mechanism. The second control mechanism is suitable for the installation of steel cage 8 in medium and deep bored piles. Since the steel cage 8 is relatively long, it is easy to deviate after it is lowered to a certain depth because there is no deviation control measure at the bottom. Therefore, the support block 130 supports the steel cage 8 to lower it to halfway, which effectively avoids the deviating of the long steel cage 8 when it is lowered because there is no deviation control at the bottom.

[0076] Working principle:

[0077] First, assemble the outer limiting seat 1 onto the top edge of the steel casing 9 through the slot 11, and use bolts for positioning. Then, insert the steel cage 8 from inside the inner limiting seat 2.

[0078] 2. Inserting the insert plate 71 into the insert plate slot 24 can push the push plate 73 to move laterally, thereby causing the abutment plate 4 to move out of the slot 23 through the push block 74, so that the arc-shaped protrusion 41 protrudes to the inner wall of the inner limit seat 2, so as to contact the steel cage 8 for limiting.

[0079] Third, the drive 32 drives the gear 33 to rotate, and the gear 33 transmits power to the tooth groove 26, causing the inner limit seat 2 to rotate relative to the outer limit seat 1, thereby driving the abutment plate 4 to rotate. The arc-shaped protrusion 41 abuts against the surface of the steel cage 8, so that the abutment plate 4 contacts different parts of the steel cage 8.

[0080] 4. Add lubricating oil into the input seat 6 through the oil hole at the top of the input seat 6, and then add lubricating oil into the transverse groove 22 through the input port 61. After running for a period of time, close the valve 53 and extract the high-temperature lubricating oil through the extraction port 51 and the oil filling port 52. At this time, the input seat 6 continues to add lubricating oil into the transverse groove 22. After the high-temperature lubricating oil extracted from the extraction seat 5 is cooled, open the valve 53 and replenish the lubricating oil into the input seat 6 through the connecting pipe 62.

[0081] Referring to Figure 10 in the specification, the present invention also provides a thickness control method for a rebar cage offset control device, comprising the following steps:

[0082] S1: The outer limiting seat 1 is assembled onto the top edge of the steel casing 9 through the slot 11, and the bolts are used for positioning. Then the steel cage 8 is inserted from inside the inner limiting seat 2.

[0083] S2: By inserting the insert plate 71 into the insert plate slot 24, the push plate 73 is pushed to move laterally, causing the abutment plate 4 to move out of the slot 23, so that the arc-shaped protrusion 41 protrudes to the inner wall of the inner limit seat 2 and contacts the steel cage 8 for limiting.

[0084] S3: The gear 33 and the tooth groove 26 are driven to make the inner limit seat 2 rotate relative to the outer limit seat 1, thereby driving the abutment plate 4 to rotate. The arc protrusion 41 abuts against the surface of the steel cage 8, so that the abutment plate 4 contacts different parts of the steel cage 8.

[0085] S4: Add lubricating oil into the input seat 6 through the oil hole at the top of the input seat 6, and then add lubricating oil into the transverse groove 22 through the input port 61. After running for a period of time, close the valve 53, and extract the high-temperature lubricating oil through the extraction port 51 and the oil filling port 52. After the high-temperature lubricating oil extracted through the extraction seat 5 is cooled, open the valve 53 and replenish the lubricating oil into the input seat 6 through the connecting pipe 62.

[0086] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
