Description

Technical Field

[0001] This invention relates to the field of bridge pier construction technology, and in particular to a construction method for integral hoisting and adjusting the alignment of the main reinforcement bars of high piers without stirrups. Background Technology

[0002] High bridge pier technology is a key focus in the construction of bridges in mountainous and coastal areas. In recent years, with the rapid development of highway construction, it has received more technical attention and improvement, and high bridge pier technology is frequently used in the construction of expressways in mountainous areas. High bridge piers are generally designed with large cross-sectional dimensions and hollow structures, with one or more layers of main steel bars on both the inner and outer surfaces. There are a large number of steel bars and a large number of steel bar connections. When constructing the vertical main bars of high bridge piers, there are two methods: one is to hoist them one by one and extend the main bars one by one. This method is slow and has low construction efficiency; the other is to hoist bundles of main bars onto the high pier construction platform at once.

[0003] In existing methods for hoisting the main reinforcement bars of high piers, most methods use hoisting clamps with a single diameter to lift the bars. However, in actual construction, different construction components require different diameters of reinforcement bars. Therefore, hoisting clamps with a single diameter have poor applicability in practical use and are difficult to adjust in real time to accommodate different reinforcement bar diameters during construction. In addition, after the existing hoisting clamps are in place, construction personnel need to manually remove the clamps, which is inefficient and affects the construction progress. Therefore, this application provides a hoisting and positioning adjustable construction method for the main reinforcement bars of high piers without stirrups to meet the requirements. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a construction method for hoisting and aligning the main reinforcement bars of high piers without stirrups in an adjustable manner, so as to solve the problems that the existing single-diameter hoisting clamps are not suitable for different reinforcement bar spacing diameters, and the hoisting clamps need to be manually removed, resulting in low efficiency.

A push block is arranged on one side of the rack. The outer surface of the push block is in contact with and slides against the inner wall of the opening. One end of the push block is pressed and in contact with the wedge.

The toothed ring is rotatably sleeved on the bottom end inside the sliding disk.

[0015] Preferably, the limiting component includes a collar, which is nested at the bottom edge of the inner wall of the lifting device.

[0018] Preferably, the wedges are arranged in a horizontal row on the inner walls of both sides of the lifting device, the shock-absorbing springs are arranged in a horizontal row on the inner walls of both sides of the lifting device, and the outer surface of the adjusting plate is elastically slidably attached to the inner wall of the lifting device.

[0019] Compared with the prior art, the present invention has at least the following beneficial effects:

[0020] In the above scheme, by setting up the linkage between the adjustment component and the fixing component, the spacing diameter of different steel bars can be adjusted in real time according to the construction requirements before the start of construction. By setting up a variable pitch screw, the spacing between the sliding discs changes, thereby adjusting the spacing between the steel bars. At the same time, the fixing component is linked. While the sliding disc adjusts the spacing of the steel bars, the linkage of the wedge block, push block and rack one drives the inclined groove slider one and inclined groove slider two to slide and engage, thereby adapting to different steel bar diameters. According to the different distribution spacing of steel bars of different diameters in actual construction, when the steel bars are installed on the hoisting fixture, the diameter and spacing of the steel bars can be adjusted by turning the handle. The mechanism is simple and can be adjusted in real time according to different construction requirements in actual use, improving the applicability of the hoisting fixture to different construction requirements.

[0021] By setting a limiting component, and through the reset and locking effect of the upper and lower locking rings and spring, when the lifting fixture is assembled with steel bars for lifting, under the influence of gravitational potential energy, the force between the lifting fixture and the adjusting plate drives the upper locking ring to slide and lock the lower locking ring, pushing out the horizontal slider. This ensures a sliding and pressing locking between the lifting fixture and the adjusting plate, preventing the adjusting plate from falling and causing construction accidents during the lifting process. Simultaneously, after concrete pouring, when the lifting fixture is lifted a second time, the force of the lifting fixture drives the horizontal slider to reset, releasing the limiting effect between the lifting fixture and the adjusting plate, and causing the fixing component to reset. This achieves automatic disassembly between the lifting fixture and the steel bars, avoiding manual disassembly and reducing construction efficiency. By utilizing the reset effect of the limiting component, the functions of limiting and disassembly are distinguished. The mechanism is simple while improving the safety of the lifting fixture during lifting and the operational efficiency during disassembly. Attached Figure Description

[0039] like Figure 1 and Figure 2 As shown in the embodiment of the present invention, a method for adjusting the alignment of the main reinforcement bars of a high pier without stirrups during integral hoisting is provided. The method includes the following steps:

[0040] S1: By adjusting the components, the fixed components are linked together, and the spacing and diameter of different steel bars are adjusted in real time according to specific construction requirements.

[0041] S2: Use slings to lift the hoisting fixture to the construction position as a whole. Use the hoisting force to drive the limit component to move and limit the connection between the hoisting fixture and the adjustment plate.

[0042] S3: After the steel bar is hoisted into place, concrete is poured at the bottom of the steel bar. After the pouring is completed, the hoisting clamp is lifted. The hoisting force is used to drive the limit component to move, release the limit between the hoisting clamp and the adjustment plate, and realize the overall disassembly of the hoisting clamp.

[0043] As one implementation method in this embodiment, such as Figures 1-4As shown, the lifting clamp in S1 includes a lifting device 1, lifting slings 2 on both sides of the lifting device 1, a wedge 3 on the inner wall of one side of the lifting device 1, a shock-absorbing spring 4 at the bottom edge of the inner wall of the lifting device 1, an adjusting plate 5 elastically connected to one side of the shock-absorbing spring 4, limit slots 50 on both sides of the bottom end of the adjusting plate 5, an opening 6 on one side surface of the adjusting plate 5, an adjusting component 7 nested at the center of one side surface of the adjusting plate 5, a fixing component 8 on the inner wall of the adjusting plate 5, a reinforcing bar 9 pressed and adhered at the center of the fixing component 8, and a limit component 10 at the bottom edge of the lifting device 1. By setting the elastic connection between the lifting device 1 and the adjusting plate 5, when lifting the lifting device 1, the gravitational potential energy and the reverse force generated during lifting drive the limit component 10 to move, elastically limiting the connection between the lifting device 1 and the adjusting plate 5, and linking the fixing component 8 to achieve the fixing, clamping and unlocking of the reinforcing bar 9. By setting the adjusting component 7 and the fixing component 8, the dual adjustment of different diameters and spacings of the reinforcing bars 9 can be achieved during the adjustment process.

[0044] As one implementation method in this embodiment, such as Figures 5-7 As shown, the adjustment component 7 includes a handle 71, which is nested at the center of one side surface of the adjustment plate 5. A helical gear 72 is rotatably mounted at one end of the handle 71, and a helical gear 73 is meshed and rotated on the other side of the handle 71. A pitch screw 74 is rotatably mounted at one end of the helical gear 73, and the pitch screw 74 is rotatably mounted on the inner wall of one side of the adjustment plate 5. There are two sets of pitch screws 74, which are installed facing each other on the same horizontal line. The thread pitch at both ends of the pitch screw 74 increases sequentially from the inside to the outside. When the operator rotates the handle 71, the handle 71 drives the helical gear 72 to rotate synchronously. The helical gear 72 drives the helical gear 73 to mesh and rotate, and the helical gear 73 drives the pitch screw 74 to rotate synchronously. By setting the handle 71 to drive the pitch screw 74, the adjustment effect of the fixed component 8 is achieved, realizing the dual adjustment of different steel bar diameters and spacings. The mechanism is simple and easy to maintain.

[0045] As one implementation method in this embodiment, such as Figures 5-7As shown, the fixing component 8 includes a sliding disk 81, which is slidably sleeved on the outer surface of the variable pitch screw 74. One side of the sliding disk 81 is slidably nested in the inner wall of the adjusting plate 5. A reciprocating screw 82 is rotatably arranged at the bottom of the sliding disk 81. A spur gear 83 is arranged at one end of the reciprocating screw 82. A rack 84 is meshed at the bottom end of the spur gear 83. The rack 84 is slidably sleeved on the edge of the top side of the sliding disk 81. A push block 85 is arranged on one side of the rack 84. The outer surface of the push block 85 is in contact with and slides against the inner wall of the opening 6. One end of the push block 85 is pressed and in contact with the wedge block 3. A slanted groove slider 86 is slidably sleeved on the outer surface of the reciprocating screw 82. The slanted groove slider 86 is located at the bottom of the inner wall of the reciprocating screw 82. The ends are arranged in a circular array. The included angle between the inclined groove sliders 86 is set to 120 degrees. The top of the inclined groove slider 86 slides against the inclined groove slider 87. The inclined groove slider 87 is nested and slides in a groove on one side of the surface of the sliding disk 81. The top of the inclined groove slider 87 is provided with a fixing block 88. The outer surface of one side of the fixing block 88 is pressed against the surface of the reinforcing bar 9. The side of the inclined groove slider 86 is provided with a rack 89. The side of the rack 89 is engaged with a toothed ring 890. The toothed ring 890 is rotated and sleeved in the bottom of the sliding disk 81. When the variable pitch screw 74 rotates, it drives the two sets of sliding disks 81 to slide in opposite directions, thereby adjusting the spacing of the reinforcing bars 9. The rotation of the variable pitch screw 74 drives the two sets of sliding disks 81 to slide in opposite directions. As the sliding disk 81 slides, it drives the push block 85 to slide on the inner wall of the opening 6. Simultaneously, the push block 85 is pressed by the wedge block 3, pushing the rack 84 to slide. While the rack 84 slides, it meshes with the spur gear 83, which rotates. The rotation of the spur gear 83 simultaneously drives the reciprocating screw 82 to rotate synchronously, causing the inclined groove slider 86 to slide on the outer surface of the reciprocating screw 82. Simultaneously, the sliding of the inclined groove slider 86 drives the rack 89 to slide. The rack 89 drives the gear ring 890 to rotate inside the sliding disk 81, causing the multiple arrayed inclined groove sliders 86 to slide synchronously. Under the engaging action of the inclined groove sliders 86 and 87, the inclined groove slider 86 drives the inclined groove slider 87... 87 slides towards the center of the sliding disk 81. Under the sliding action of the inclined groove slider 87, the steel bar 9 is clamped and fixed by the fixing block 88, thus achieving the effect of fixing and clamping the steel bar 9. By setting the push block 85 and the wedge block 3 to work together, the variable pitch screw 74 drives the sliding disk 81 to slide to adapt to the diameter of the steel bar 9. At the same time, the force generated by the push block 85 and the wedge block 3 is utilized. By setting the meshing linkage of the rack 84 and the flat gear 83, the inclined groove slider 86 and the inclined groove slider 87 are driven to slide and engage with each other, thus achieving the effect of fixing and clamping the steel bar 9 by the fixing block 88. This allows for the adjustment of the spacing of the steel bars 9 while adapting to different diameters of the steel bars 9, improving the applicability of the equipment.

[0046] As one implementation method in this embodiment, such as Figure 8As shown, the limiting component 10 includes a collar 101, which is nested at the bottom edge of the inner wall of the lifting device 1. A limiting groove 1010 is provided on the middle surface of the inner wall of the collar 101. An upper retaining ring 102 is slidably disposed at the top of the inner wall of the collar 101. A pressure plate 103 is provided at the top of the upper retaining ring 102. A pressure block 104 is slidably pressed at the top of the pressure plate 103. The pressure block 104 is fixedly installed at one edge of the top of the adjusting plate 5. A lower retaining ring 105 is slidably engaged at the bottom of the upper retaining ring 102. The outer surface of the lower retaining ring 105 is slidably attached to the inner wall of the collar 101. A push rod 106 is provided at the bottom of the lower retaining ring 105. A spring is laid on the outer surface of the push rod 106. Spring 107 is elastically connected at its top end to the bottom end of the lower retaining ring 105. The bottom end of spring 107 is elastically connected to the bottom end of the inner wall of the collar 101. A fixed box 108 is connected through the bottom end of the collar 101. A transverse slider 1081 is nested elastically within the inner wall of the fixed box 108. A second spring 1082 is elastically installed at one end of the transverse slider 1081. One end of the second spring 1082 is elastically installed at one end of the inner wall of the fixed box 108. One end of the transverse slider 1081 is pressed and adhered to the bottom end of the push rod 106. The outer surface of one end of the transverse slider 1081 adheres to the inner wall of the limiting slot 50 for limiting sliding. After the reinforcing bar 9 is fixed in place, the lifting device 1 is lifted by the sling 2. Lifting: Due to the elastic connection between the adjusting plate 5 and the lifting device 1, under the influence of gravitational potential energy, the adjusting plate 5 elastically presses down against the inner wall of the lifting device 1. The adjusting plate 5 drives the pressure block 104 to squeeze the pressure plate 103. The pressure plate 103 drives the upper retaining ring 102 to press down. At the same time, the upper retaining ring 102 presses down and drives the push rod 106 to press down through the lower retaining ring 105. Under the action of the limiting groove 1010, the lower retaining ring 105 is locked after pressing down, keeping the push rod 106 in the ejected state. At the same time, the push rod 106 presses down and squeezes against the transverse slider 1081, pushing the transverse slider 1081 out of the fixed box 108 and engaging with the inner wall of the limiting slot 50, thus realizing the reversal. The locking connection between section plate 5 and lifting device 1 ensures that push block 85 and wedge block 3 are in a squeezed and fitted state, thus ensuring the fixing effect of reinforcing bar 9. Similarly, after the concrete is poured, lifting device 1 is lifted by lifting cable 2. Under the reverse force of concrete, adjusting plate 5 is pressed down, upper retaining ring 102 drives lower retaining ring 105 to press down, lower retaining ring 105 is in contact with limiting groove 1010 and returns to its original position, driving push rod 106 to return to its original position. Under the action of spring 2 1082, horizontal slider 1081 is forced to return to its original position, thus releasing the locking state between adjusting plate 5 and lifting device 1, thereby releasing the fixing clamping effect of reinforcing bar 9 and achieving automatic dismantling effect.

[0047] As one implementation method in this embodiment, such as Figures 1-4 As shown, the wedge blocks 3 are arranged in a horizontal line on both sides of the inner wall of the lifting device 1, the shock-absorbing springs 4 are arranged in a horizontal line on both sides of the inner wall of the lifting device 1, and the outer surface of the adjusting plate 5 is elastically slidably attached to the inner wall of the lifting device 1.

[0048] The technical solution provided by this invention, through the linkage between the adjustment component and the fixing component, allows for real-time adjustment of the spacing and diameter of different reinforcing bars according to construction requirements before construction begins. By setting a variable-pitch screw, the spacing between the sliding discs changes, achieving the effect of adjusting the reinforcing bar spacing. Simultaneously, the fixing component is linked; while the sliding disc adjusts the reinforcing bar spacing, the linkage of the wedge block, push block, and rack one causes the inclined groove slider one and inclined groove slider two to slide and engage, achieving the effect of adapting to different reinforcing bar diameters. Based on the different distribution spacing of reinforcing bars of different diameters in actual construction, when installing the reinforcing bars on the hoisting fixture, the diameter and spacing of the reinforcing bars can be adjusted simultaneously by rotating the handle. The mechanism is simple and can be adjusted in real-time according to different construction requirements in actual use, improving the applicability of the hoisting fixture to different construction requirements.

[0049] By setting a limiting component, and through the reset and locking effect of the upper and lower locking rings and spring, when the lifting fixture is assembled with steel bars for lifting, under the influence of gravitational potential energy, the force between the lifting fixture and the adjusting plate drives the upper locking ring to slide and lock the lower locking ring, pushing out the horizontal slider. This ensures a sliding and pressing locking between the lifting fixture and the adjusting plate, preventing the adjusting plate from falling and causing construction accidents during the lifting process. Simultaneously, after concrete pouring, when the lifting fixture is lifted a second time, the force of the lifting fixture drives the horizontal slider to reset, releasing the limiting effect between the lifting fixture and the adjusting plate, and causing the fixing component to reset. This achieves automatic disassembly between the lifting fixture and the steel bars, avoiding manual disassembly and reducing construction efficiency. By utilizing the reset effect of the limiting component, the functions of limiting and disassembly are distinguished. The mechanism is simple while improving the safety of the lifting fixture during lifting and the operational efficiency during disassembly.
