Description

Technical Field

[0001] This invention relates to the field of bridge construction technology, and in particular to a construction device for steel reinforcement components for bridge piers. Background Technology

[0002] Bridge piers are a crucial structural component. The reinforcement binding of pier piers is primarily done manually, with each rebar installed individually, resulting in low efficiency and limited quality control. Currently, some pier piers utilize prefabricated rebar components, while others employ a matching process. In this method, adjacent sections of the main reinforcement bars are connected using threaded sleeves during positioning. Once the main reinforcement bars are securely welded to the stirrups, the threaded sleeves are disassembled, and the previous section is transported to the pier for hoisting and installation, with the next section then matching. Other rebar components use extruded conical sleeves, where the main reinforcement bar joints can be on the same cross-section, eliminating the need for matching. However, both of these rebar component methods have significant drawbacks: matching rebar components are cumbersome to install and cannot achieve true effective matching, making it difficult to install even matched main reinforcement bar joints during installation. The extruded conical sleeve method is also extremely costly, resulting in poor overall economic efficiency and hindering widespread adoption. Summary of the Invention

[0003] This invention provides a construction device for pier column steel reinforcement components, which solves the technical problems of complex manufacturing process, long processing time, high cost, low construction efficiency, and unsuitability for large-scale use of pier column steel reinforcement components.

[0021] In the preferred embodiment, before S9, the bracket is removed from the tray, and the two alignment hangers located on the upper and lower sides of the middle body of the mesh are placed facing each other, with the lower alignment hanger placed on the tray.

[0022] In the preferred embodiment, in S10, the alignment bracket located on the upper side is supported and fixed by multiple legs, with the lower part of the legs fixed to the adjusting pad.

[0023] In the preferred embodiment, in S12, the main reinforcement bars are connected to the pre-embedded reinforcement bars on the pier column through the second threaded sleeve and the extrusion cone sleeve respectively. After they are fixed in place, the upper alignment hanger is removed and lifted and removed using a hook, while the alignment hanger on the pallet is removed at the same time.

[0024] In the preferred embodiment, the system includes a positioning jig, a first operating platform, a bracket, a lifting device, an alignment bracket, and a second operating platform. The positioning jig is used to complete the welding of the steel mesh. The first operating platform includes two first support frames arranged opposite each other.

[0026] The upper side of the lifting device is hinged with a folding plate for connecting with the upper crossbeam. Multiple positioning sleeves are evenly arranged on the alignment frame. The diameter of the positioning sleeves matches the diameter of the main reinforcement. Flexible cables are detachably provided on both sides of the lifting device. Multiple hooks are evenly arranged on the flexible cables.

[0027] The second operating platform includes two second support frames arranged opposite each other. The bottoms of the two second support frames are connected by a pad plate.

[0030] The beneficial effects of this invention are as follows: This solution facilitates material sourcing and rapid fabrication by disassembling the reinforcing mesh. The positioning jig ensures the installation accuracy of different stirrups and hook bars, thereby guaranteeing the fabrication accuracy of the reinforcing mesh. Simultaneously, the overall welding is performed robotically. The reinforcing mesh is fabricated in the factory and then transported to the project construction site for on-site welding and assembly. Different reinforcing meshes are lifted using flexible cables and hooks, avoiding excessive space occupation and ensuring relatively uniform spacing between different meshes, resulting in good overall fabrication accuracy. After the reinforcing mesh is divided, the main reinforcing bars are directly inserted into the mesh body, and a few main reinforcing bars are welded to the contact points of multiple layers of reinforcing mesh to form the reinforcing mesh component. Compared with other processes, this method features simple operation, good adaptability of main reinforcing bar connections, ensures construction progress, and has good economic benefits.

Detailed Implementation

[0055] like Figure 1-18 A construction device for reinforcing steel components of a pier column includes the following steps:

[0056] S1. Design the shape and dimensions of the steel mesh 6 according to the requirements of the pier 18;

[0057] S2. Weld the steel mesh 6 on the positioning frame using the first stirrup 1, the second stirrup 2, the first hook bar 3, the second hook bar 4, and the third stirrup 5. According to the size requirements of the pier column steel stirrups, make a stirrup positioning frame. The frame is equipped with stirrup positioning slots and hook bar positioning slots. The steel positioning slots are based on the center line of the steel bar. The slot width is 3mm larger than the stirrup diameter, and the slot positioning height deviation is 5mm.

[0058] The stirrups and hook reinforcement units are pre-bent and fabricated on a stirrup bending machine. The bending radius deviation of the stirrups is 1cm, and the spacing deviation of the bent edges of the hook reinforcements is 5mm. A robotic arm automatically picks up the stirrup units and places them in the corresponding slots of the rebar mesh jig. Then, the positioning clamps on the jig clamp the stirrup units, and a welding robotic arm welds adjacent ring-shaped stirrup units together to form a ring. After the outer and inner rings of the stirrups in the same layer are fabricated, the robotic arm picks up and installs the hook reinforcements in the corresponding slots. The hook reinforcement units are welded together with the inner and outer rings of the stirrups by the robotic arm to connect with the stirrups and form mesh sheets. After the sheets are fabricated, a handling robotic arm directly stacks the rebar mesh sheets onto designated brackets. The brackets can precisely hold the rebar mesh sheets, ensuring that multiple rebar mesh sheets are arranged neatly and the outer contours of the stirrups are on the same plane.

[0059] S3. Place the completed steel mesh 6 into the bracket 8 respectively. When the design capacity is reached, move it to the first operating platform 7. After placing a certain number of steel mesh on the bracket 8, transport it together with the bracket to the component assembly frame via a flatbed truck. Ensure smooth and convenient overall flow, high production efficiency, and stable cycle time.

[0060] S4. By adjusting the vertical beams 706 on the two first support frames 701, the two vertical beams 706 are kept in an open-up state. Then, the bracket 8 and the steel mesh 6 are hoisted together and placed on the upper support plate 707 of the first fixing member 704 using the hook 9 and the cable 10. This ensures stable support for the bracket 8 and high overall construction precision. The support plate adopts a spiral jacking method, which makes it easy to ensure that the steel mesh 6 is in a horizontal installation state.

[0061] S5. Disconnect the connection between the hook 9 and the bracket 8, and then install the lifting device 11 at the bottom of the hook 9. Install the flexible cable 12 on both sides of the lifting device 11.

[0062] S6. Move the lifting device 11 to the uppermost steel mesh 6, and then hang the steel mesh 6 of each layer on the corresponding hooks 13 on the flexible cable 12 in sequence; the hooks 13 can conveniently and quickly hang and fix the steel mesh 6.

[0063] Six flexible cables 12 are used. Hooks 13 on the flexible cables 12 are hung on the outside of the component lifting device, one at each of the four corners and one on each of the long sides. The steel mesh is lifted sequentially and hooked onto the hooks. A staggered limiting fixture is provided corresponding to the main reinforcement 15. The positioning rods 1602 are staggered, arranged in order of height, with the positioning rods 1602 and the main reinforcement 15 directly opposite each other. A first threaded sleeve 17 is installed at the other end of the main reinforcement. The diameter of the first threaded sleeve 17 is larger than the positioning hole of the main reinforcement on the alignment hanger 14. This allows the main reinforcement to be supported on the alignment hanger 14. The other end is supported by the main reinforcement positioning rod 1602.

[0064] S7. Lift the hook 9 upwards to hoist the steel mesh 6 inside the bracket 8 in sequence and complete the separation of the steel mesh 6 to form the mesh intermediate body 25;

[0065] S8. Continue to lift the hook 9 to fix the lifting device 11 and the upper crossbeams 703 on both sides, and then disconnect the hook 9 from the lifting device 11.

[0066] S9. Install the alignment bracket 14 on the lower side of the hook 9, and fix the alignment bracket 14 on the lower side of the bracket 8. Pass the main rib 15 through the positioning sleeve 24 on the alignment bracket 14 into the mesh intermediate body 25, and fix the upper part of the mesh intermediate body 25 through the first threaded sleeve 17.

[0067] The top posture of the main reinforcement bars was checked using a total station to ensure that the outer contours of all steel mesh panels were on the same plane. Then, a total of 8 main reinforcement bars at the four corners, the middle of the long side, and the middle of the short plate were welded firmly to the steel mesh panel. Then, four long Φ20 round steel bars (2 short and 2 long) were used to clamp the main reinforcement bars 15 in the middle in four directions and tied to the bottom layer of stirrups with tie wire. The same method was used for the inner main reinforcement bars and the steel mesh panel to form a semi-stable steel reinforcement component with the steel mesh panel and the main reinforcement bars.

[0068] S10. Limit the mesh intermediate body 25 by the vertical supports 1601 inside the two second operating platforms 16, adjust the height of the mesh intermediate body 25, and support the bottom of the mesh intermediate body 25 on the positioning rod 1602.

[0069] S11. After the intermediate body 25 of the mesh and the main reinforcement 15 are stable, the intermediate body 25 of the mesh and the main reinforcement 15 are fixed by binding and welding to form the steel reinforcement component 26; the main reinforcement that is welded to the main reinforcement of the steel mesh is connected to the main reinforcement of the previous segment through the extrusion cone sleeve 20, and other main reinforcements are connected to the corresponding main reinforcements through the second threaded sleeve 21. When connecting the second threaded sleeve 21, the main reinforcement does not need long and short wires, and the main reinforcement of the flexible connection can be directly screwed into the sleeve.

[0070] S12. Hoist the steel reinforcement component 26 to the upper part of the pier column 18 and fix it with the pre-embedded reinforcement 19 for subsequent pouring process; hoist the steel reinforcement component 26 together with the alignment hanger 14 onto the pier column. The alignment hanger 14 is equipped with a support rod at the bottom, which is supported on the already poured concrete surface. The other main reinforcement bars 15 rest on the main reinforcement bars connected to the previous segment. A total station prism is set on the eight main reinforcement bars welded to the steel mesh 6 to detect the posture of the component. Then, the component is adjusted by pushing it with a hydraulic cylinder, thereby adjusting the posture of the steel reinforcement component; close the formwork for pouring and curing. Before pouring, the second threaded sleeve at the end of the main reinforcement bar needs to be fitted with a protective sleeve to prevent it from being contaminated by concrete and affecting its use.

[0071] S13. Repeat S2 to S12 until all steel reinforcement components 26 are completed.

[0072] Based on the planar layout of the main reinforcement bars 18 and the height of the main reinforcement bars 15, a jig for assembling the steel reinforcement component 26 is designed. This jig is used for positioning the multi-layer steel mesh 6, adjusting and fixing the spacing between the mesh pieces, and supporting and positioning the component during hoisting. After the steel mesh is fabricated inside the mesh jig, it is transported to the component jig (first operating platform 7), and the spacing of the steel mesh 6 is adjusted. Then, the main reinforcement bars 15 are inserted. After approximately 20% of the main reinforcement bars at the fixed position are firmly welded to the multi-layer mesh, the steel reinforcement component 26 is hoisted onto the tower as a whole. After measuring and adjusting the posture of the mesh and the main reinforcement bars, the main reinforcement bars are then connected. The welded main reinforcement bars are connected using extrusion tapered sleeves 20, and other main reinforcement bars are connected using second threaded sleeves 21.

[0073] This technology eliminates the need for matching and installation of the main reinforcing bars in the fabrication of steel reinforcement components. The main reinforcing bar connections primarily utilize traditional threaded sleeve connections, resulting in low costs. The steel mesh is fabricated within a jig, and after inserting the main reinforcing bars for shaping, the spacing of the steel mesh is widened to form a steel reinforcement component primarily composed of steel mesh.

[0074] In the preferred embodiment, in step S3, by adjusting the positions of the first baffles 801 and the second baffles 802 on both sides of the bracket 8, the spacing between the two first baffles 801 is ensured to match the length of the steel mesh 6, and the two sides of the steel mesh 6 are precisely fitted against the inner sides of the first baffles 801. The bracket 8 is adjustable, which facilitates initial support of weight and subsequent easy removal.

[0075] In the preferred embodiment, in step S5, after the bracket 8 and hook 9 are separated, the bolts 804 on the second baffle 802 and the base plate 803 are removed, the locking pins on the second baffle 802 and the base plate 803 are released, and the second baffle 802 is adjusted from a vertical state to a horizontal state using the bolts 804, completely releasing the constraint on the steel mesh 6. This structure makes the subsequent separation and lifting of the steel mesh 6 more convenient and avoids interference after the bracket 8 is completely removed.

[0076] In the preferred embodiment, in step S5, a flexible cable 12 of appropriate length is pre-cut according to the height of the reinforcing steel component 26. Then, a fixing component 22 is installed on the flexible cable 12. The hook 13 is connected and fixed to the flexible cable 12 via the fixing component 22. Multiple fixing components 22 are evenly distributed on the flexible cable 12, and the distance between two fixing components 22 is the spacing between two adjacent reinforcing steel mesh pieces 6. This structure facilitates accurate installation of the hook 13 at different positions, allows for convenient adjustment, and enables the distance between different fixing components 22 to be changed according to design requirements, resulting in better performance.

[0077] In the preferred embodiment, before step S9, the bracket 8 is removed from the support plate 707, and the two alignment hangers 14 located on the upper and lower sides of the mesh middle body 25 are placed facing each other, with the lower alignment hanger 14 placed on the support plate 707. This structure facilitates the insertion of the main reinforcement 15, provides a larger overall construction space, and ensures construction convenience.

[0078] In the preferred embodiment, in S10, the alignment hanger 14 located on the upper side is supported and fixed by multiple legs 27, the lower part of which is fixed to the adjusting pad 1603. This structure allows the adjusting pad 1603 to stably adjust the state of the alignment hanger 14, keeping it in a relatively horizontal state, thereby ensuring good welding quality between the main rib 15 and the mesh intermediate body 25.

[0079] In the preferred embodiment, in S12, the main reinforcing bars 15 are connected to the pre-embedded reinforcing bars 19 on the pier column 18 via the second threaded sleeve 21 and the extrusion cone sleeve 20, respectively. After being fixed in place, the upper alignment hanger 14 is removed and lifted off using the hook 9, while the alignment hanger 14 on the support plate 707 is also removed. This avoids the high economic cost of using extrusion cone sleeves 20 throughout, and the fixing points are set as needed, resulting in overall stable stress and saving materials.

[0080] like Figure 19-22 In the preferred embodiment, the system includes a positioning frame, a first operating platform 7, a bracket 8, a lifting device 11, an alignment bracket 14, and a second operating platform 16. The positioning frame is used to complete the welding of the steel mesh 6. The first operating platform 7 includes two first support frames 701 arranged opposite to each other. The upper and lower sides of the first support frames 701 are respectively provided with a lower crossbeam 702 and an upper crossbeam 703. A first fixing member 704 is provided on the lower crossbeam 702, and a second fixing member 705 is slidably provided on the upper crossbeam 703. The second fixing member 705 is connected to the first fixing member 704 through a vertical beam 706. The second fixing member 705 and the vertical beam 706 are hinged. A support plate 707 is provided on the upper support of the first fixing member 704.

[0081] The bracket 8 includes a base plate 803. Two first baffles 801 are slidably provided on both sides of the base plate 803 along its length. The bottom of the first baffles 801 is connected to the base plate 803 by bolts 804. Two sliding plates 806 are slidably provided on both sides of the base plate 803 along its width. The sliding plates 806 are connected to the base plate 803 by bolts 804. A second baffle 802 is hinged to the sliding plates 806 by a shaft 805. Bolts 804 pass through the second baffle 802 and the base plate 803. The second baffle 802 and the base plate 803 can be fixed by bolts 804. The second baffle 802 can be fixed and locked in a perpendicular state to the base plate 803 by bolts 804.

[0082] The upper side of the lifting device 11 is hinged with a folding plate for connecting with the upper crossbeam 703. Multiple positioning sleeves 24 are evenly arranged on the alignment hanger 14. The diameter of the positioning sleeves 24 matches the diameter of the main rib 15. Flexible cables 12 are detachably provided on both sides of the lifting device 11. Multiple hooks 13 are evenly arranged on the flexible cables 12.

[0083] The second operating platform 16 includes two opposing second support frames 1604, the bottoms of which are connected by a pad 1605. Multiple adjusting pads 1603 are provided on the pad 1605. A vertical support 1601 is fixed to the pad 1605, and the pad 1605 also has adjusting pads 1603 for fixing the support legs 27. This structure allows for large-scale, rapid production of the steel mesh 6 in the factory. After production, it is transported to the project construction site for the fabrication of the steel reinforcement components 26. Due to the large size and heavy weight of the steel mesh 6, the combination of factory and construction site operations ensures high overall construction efficiency.

[0084] In the preferred embodiment, the hook 13 is connected to the flexible cable 12 via a fixing component 22. The fixing component 22 includes two parallel connecting blocks 2201. A through groove 2202 is provided through the middle of the connecting block 2201. A first notch 2203 is provided on one side of the connecting block 2201. Two through holes 2204 are provided through the first notch 2203. A limiting groove 2205 is provided on one side of the through groove 2202. The flexible cable 12 passes through the through groove 2202, and the hook 13 is located in the limiting groove 2205. The U-shaped rod 2210 fixes the hook 13 and the flexible cable 12 with a nut 2209. This structure allows the hook 13 to be stably installed on the flexible cable 12, while maintaining overall stability under force. The hook 13 has high installation accuracy, which facilitates more uniform placement of the reinforcing mesh 6 and improves the overall performance.

[0085] In the preferred embodiment, the limiting groove 2205 is provided with a taper 2206, and the small ends of the two limiting grooves 2205 are arranged opposite each other. A locking element 23 is also provided between the two connecting blocks 2201. The locking element 23 includes a sealing plate 2301, and a second notch 2303 is provided on the sealing plate 2301. A constraint sleeve 2302 is provided on one side of the second notch 2303. The inner diameter of the constraint sleeve 2302 matches the outer diameter of the flexible cable 12. The constraint sleeve 2302 passes through the limiting groove 2205. An ear plate 2207 is provided on the outer side of the connecting block 2201. The two ear plates 2207 on the same side are connected by a locking pin 2208 and a nut 2209. The locking element 23 is made of rubber. When the locking pin 2208 locks the two connecting blocks 2201, the sealing plate 2301 is squeezed, which will make the constraint sleeve 2302 fit more tightly on the flexible cable 12. At the same time, since the limiting groove 2205 is provided with a taper 2206, the two connecting blocks 2201 are connected to form a taper interlocking effect. The constraint sleeve 2302 is provided with a wire mesh, which can maintain good elasticity while better fitting on the flexible cable 12, thereby providing a stable holding force for the hook 13, ensuring that the hook 13 has a strong load capacity, and ensuring the safe and stable hoisting of the steel mesh 6.
