Description

Technical Field

[0001] This application relates to the technical field of tower column frame construction, and in particular to a rapid positioning device for high-altitude installation of main tower steel reinforcement frame. Background Technology

[0002] A cable-stayed bridge, also known as a skeletal bridge, is a type of bridge where the main girder is directly anchored to the bridge towers by numerous cables. It is a structural system composed of compression-bearing towers, tension-bearing cables, and bending-resistant girder sections. It offers advantages such as high load-bearing capacity, reduced building height, lighter structural weight, and material savings. A cable-stayed bridge mainly consists of main towers, main girder, and stay cables.

[0003] Currently, when constructing a main tower, most methods involve first tilting the steel reinforcement frame at a certain angle before pouring concrete to form the tilted main tower. However, some main towers have a vertical lower section and a tilted upper section. When constructing this type of main tower, the current method is to set the steel reinforcement frame vertically, then bend a portion of the steel reinforcement, and finally pour concrete according to the direction of the steel reinforcement, thus achieving the construction of this type of main tower.

[0004] However, in the above-mentioned technology, when it is necessary to bend the steel bars, the construction workers use special tools for bending steel bars. However, the construction of the main tower requires a lot of steel bars, and the construction workers can only bend multiple steel bars one by one, which is inefficient and leads to slow construction progress. Summary of the Invention

[0005] To improve the efficiency of construction workers in bending steel bars, this application provides a rapid positioning device for high-altitude installation of the main tower steel bar skeleton.

[0006] The technical solution for a rapid positioning device for high-altitude installation of main tower steel reinforcement cage provided in this application is as follows:

[0007] A rapid positioning device for high-altitude installation of a main tower steel reinforcement frame includes:

[0008] A foundation rebar platform is used to install rebar. The upper surface of the foundation rebar platform is provided with multiple frames, which are located on the side of the rebar, and at least two of the frames are arranged opposite each other.

[0009] The fixing plate is provided with at least three fixing plates, and the three fixing plates are provided with multiple fixing holes for the reinforcing bars to pass through;

[0010] A bending lifting assembly is mounted on the platform and is used to drive the fixed plate to move along the direction of the steel reinforcement and to drive the fixed plate to rotate around a certain point on its side wall.

[0011] A fastener is used to fix the fixing plate to a certain point on the reinforcing bar.

[0012] By adopting the above technical solution, in the initial state, three fixing discs are stacked on the foundation rebar platform, with the fixing holes on the three fixing discs connected sequentially from top to bottom. Then, the bending and lifting assembly moves the bottommost fixing disc upward a certain distance. Next, the rebar is inserted through the fixing hole on the topmost fixing disc, with one end of the rebar abutting against the foundation rebar platform. Then, the other end of the rebar is fixed to the foundation rebar platform. Then, the bending and lifting assembly moves the three fixing discs down to the upper surface of the foundation rebar platform, fixing the bottommost fixing disc to the foundation rebar platform. Next, the bending and lifting assembly moves the topmost fixing disc up to the top of the rebar, and the topmost fixing disc is fixed to the top of the rebar by a fastener. Finally, the bending and lifting assembly moves the middle fixing disc up to the part of the rebar that needs to be bent, and the middle fixing disc is fixed to the top of the rebar by a fastener. Here, the bending lifting assembly is used again to bend the reinforcing bars, allowing all the reinforcing bars in multiple fixing holes to bend simultaneously. This greatly simplifies the bending process, improving the efficiency of the workers and accelerating the construction progress. Furthermore, this device ensures that all reinforcing bars are bent to the same degree, eliminating the need for later corrections. Additionally, the fixing plate acts as a horizontal support, saving material costs. Moreover, since the uppermost part of the bent reinforcing bars may interlock due to stress variations, increasing the difficulty of subsequent construction, this device also uses a fixing plate at the highest point of the reinforcing bars to ensure even alignment of the bent bars, reducing construction difficulty and further improving worker efficiency.

[0013] Optionally, the bending lifting assembly includes a lifting device, a connecting frame, and a bending component;

[0014] There are two lifting devices, each corresponding to one of the two oppositely arranged platforms, and the two lifting devices are respectively installed on the two oppositely arranged platforms.

[0015] The connecting frame is provided in two parts, and each of the two connecting frames corresponds to one of the two lifting devices. One end of the connecting frame is connected to the lifting device, and the other end of the connecting frame is rotatably connected to the fixed plate through a connecting piece.

[0016] A bending element, which is mounted on one of the connecting frames, is used to drive the fixed disk to rotate along the other connecting frame.

[0017] By adopting the above technical solution, when it is necessary to move the fixed plate up or down, the fixed plate and the connecting frame are connected by the connecting piece, and then the fixed plate is moved up or down by the lifting device. When it is necessary to bend the steel bar, the bending piece drives the fixed plate to rotate around the connection between the fixed plate and the connecting frame. While the fixed plate is rotating, the wall of the fixing hole on the fixed plate will generate a thrust on the steel bar, thereby bending the steel bar. Thus, the bending lifting component achieves the effect of bending the steel bar and moving the fixed plate.

[0018] Optionally, the connector includes a connecting block, a connecting seat, a bidirectional cylinder, a connecting rod, and a plug rod. The connecting block is mounted on the fixed plate and has a plug hole. The connecting seat is mounted on the connecting frame. The bidirectional cylinder is mounted on the connecting seat. There are two connecting rods, which are arranged opposite each other and are respectively mounted on the two output shafts of the bidirectional cylinder. There are two plug rods, which correspond one-to-one with the two connecting rods. The two plug rods are respectively arranged on the opposite surfaces of the two connecting rods, and the sidewalls of the two plug rods slide against the wall of the plug hole.

[0019] By adopting the above technical solution, the insertion rod can be slidably inserted into the insertion hole on the connecting block, or it can be slidably pulled out. This achieves the hinge connection between the fixed plate and the connecting frame, as well as the detachable connection between the lifting device and the fixed plate, making it convenient for construction personnel to quickly move the next fixed plate.

[0020] Optionally, the bending member includes a telescopic device located below the fixed plate and between the connecting frame and the lifting device. The telescopic device is rotatably connected to the lifting device, and its output end is fixedly connected to the connecting frame.

[0021] By adopting the above technical solution, the output end of the telescopic device extends, thereby applying an upward oblique thrust to the fixed plate through the connecting frame and connecting parts. As a result, the fixed plate rotates around its connection with another connecting frame. While the fixed plate rotates, it applies a horizontal thrust to the reinforcing bar, thereby achieving the bending effect of the bending part on the reinforcing bar.

[0022] Optionally, multiple fasteners are provided, and the multiple fasteners are evenly spaced along the length of the reinforcing bar.

[0023] By adopting the above technical solution, the fixing plate can be placed at any position on the reinforcing bar, thus providing more adjustment space for the connection between the fixing plate and the reinforcing bar, thereby improving the practicality of the fixing plate.

[0024] Optionally, the fixing component includes a locking block and a return spring. A locking groove adapted to the locking block is formed on the peripheral wall of the reinforcing bar. One end of the locking block is rotatably connected to the groove wall at the lower end of the groove. One end of the return spring is connected to the end face of the locking block opposite to the groove, and the other end of the return spring is connected to the groove wall of the groove.

[0025] By adopting the above technical solution, when the fixing plate moves from the lower right to the upper right along the length of the reinforcing bar, the wall of the fixing hole on the fixing plate will apply a pressure close to the reinforcing bar to the locking block. At this time, the locking block will be squeezed into the locking groove, and the return spring will be in a compressed state. When the fixing plate moves above the locking block, the return spring will reset and drive the locking block away from the locking groove. At this time, the locking block abuts against the lower end face of the fixing plate, and the fixing plate will not be able to move down under the action of gravity, thereby realizing the fixing effect of the fixing component on the fixing plate.

[0026] Optionally, the fixed disk is provided with multiple flow guide holes.

[0027] By adopting the above technical solution, since the fixed plate is used as a transverse reinforcing bar in this structure, when the reinforcing bar is sealed and cement needs to be poured, the guide hole on the fixed plate can allow cement to pass through, thereby speeding up the cement pouring work and improving construction efficiency.

[0028] Optionally, the plurality of the flow guide holes are evenly spaced around the axis of the fixed disk.

[0029] By adopting the above technical solution, cement can flow relatively evenly into the space between each steel bar, thus minimizing the possibility of uneven stress on the main tower due to uneven cement pouring.

[0030] Optionally, the platform can be detachably connected to the foundation reinforcement platform.

[0031] By adopting the above technical solution, once the main tower is completed, the platform and bending lifting assembly can be disassembled for future use; in addition, the platform can also be reused, thereby reducing resource waste and saving costs.

[0032] Optionally, reinforcing ribs are provided between the multiple platforms.

[0033] By adopting the above technical solution, the stability of the platform can be improved, thereby improving the stability of the bending lifting component and the fixed plate, and further improving the stability of the entire device.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. The bending lifting assembly can rotate the fixed plate to bend all the steel bars at once, simplifying the bending process and improving the efficiency of construction workers. Furthermore, workers can complete the bending work using the bending lifting assembly, eliminating the need for working at heights and reducing safety hazards. In addition, the fixed plate not only fixes and limits the vertical steel bars, facilitating construction, but also functions as a horizontal steel bar, increasing its versatility and saving materials.

[0036] 2. The setting of the guide holes on the fixed plate further speeds up the cement pouring process. Moreover, the guide holes are evenly spaced around their own axis, which makes the cement pouring more uniform and the mass density distribution of the main tower more uniform, thus making its structural strength higher.

[0037] 3. The detachable connection between the platform and the foundation steel reinforcement platform allows the platform and bending lifting components to be recycled and reused, thereby further saving materials and improving resource utilization. Attached Figure Description

[0047] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0048] This application discloses a rapid positioning device for high-altitude installation of a main tower's steel reinforcement cage. (Refer to...) Figure 1 A rapid positioning device for high-altitude installation of main tower steel reinforcement frame includes a foundation steel reinforcement platform 1, a fixing plate 2, a bending and lifting assembly 3, and a fixing component 4 (combined with...). Figure 3 ).

[0049] In this embodiment, the foundation steel reinforcement platform 1 is set to a square shape, which is mainly used to install steel reinforcement 5, similar to a foundation device. Of course, in other optional embodiments, the shape of the foundation steel reinforcement platform 1 can be circular or other shapes, or the foundation steel reinforcement platform 1 can be omitted, and the steel reinforcement 5 can be installed directly on the foundation on site.

[0050] Multiple frames 11 are respectively provided at the edges of the three directions on the upper surface of the foundation reinforcement platform 1. In this embodiment, four frames 11 are provided, and all four frames 11 are arranged in the vertical direction. Of course, in other optional embodiments, the number of frames 11 can be determined according to the actual situation.

[0051] In addition, multiple reinforcing ribs 12 are provided between the four supports 11 to improve the connection strength between the supports 11, thereby improving the connection strength of the entire device. It should be noted that, under normal circumstances, reinforcing ribs 12 should be provided in all four directions of the upper surface of the foundation reinforcement support 1. However, in this embodiment, one side is not provided with reinforcing ribs 12 to allow for sufficient transport space when moving the fixed plate 2. Of course, in other alternative embodiments, all four sides of the upper surface of the foundation reinforcement support 1 can be provided with reinforcing ribs 12, and then the fixed plate 2 can be placed from above the support 11 onto the upper surface of the foundation reinforcement support 1 using a crane or other device.

[0052] To reduce manufacturing costs, the platform 11 is detachably connected to the foundation steel reinforcement platform 1 (not shown in the figure). It can be connected by bolts or tenons. After a steel frame structure is installed, the platform 11 can be disassembled for future use, thereby realizing the recycling of the platform 11 and saving materials.

[0053] Continue to refer to Figure 1 In this embodiment, the fixing plate 2 is circular to accommodate the shape of most main towers. In other optional embodiments, the shape of the fixing plate 2 can be determined according to the shape of the cross-section of the main tower. Furthermore, for ease of demonstration, only three fixing plates 2 are shown in this embodiment. In actual or other embodiments, the number of fixing plates 2 can be determined according to the length of the reinforcing bar 5. During the bending of the reinforcing bar 5, all three fixing plates 2 are horizontally arranged and coaxially arranged in the vertical direction.

[0054] The fixing plate 2 has multiple fixing holes 21 for the reinforcing bars 5 to pass through (in combination) Figure 5 The multiple fixing holes 21 are arranged in a circular shape and are evenly spaced around the axis of the fixing plate 2, so that the multiple steel bars 5 can be arranged in a circular array, making the stress on each steel bar 5 more uniform, thereby improving the structural strength of the entire steel frame.

[0055] Reference Figure 2 The bending lifting assembly 3 includes a lifting device 31, a connecting frame 32, a bending component 33, and a connecting component 34.

[0056] In this embodiment, two lifting devices 31 are provided, both mounted on the frame 11 and arranged opposite to each other. The lifting device 31 in this embodiment is a combination of a lead screw and a nut, wherein the nut is connected to the fixed plate 2. The up-and-down movement of the nut drives the fixed plate 2 to move up and down (existing technology, not described in detail here). Of course, in other optional embodiments, it can also be a hydraulic cylinder, pneumatic cylinder, or other device capable of moving moving parts up and down.

[0057] There are also two connecting frames 32, each corresponding to one of the two lifting devices 31. One end of the connecting frame 32 is fixedly connected to the nut in the lifting device 31.

[0058] There are two corresponding connectors 34, with each connector 34 corresponding to one of the two connecting brackets 32. Each connector 34 includes a connecting block 341, a connecting seat 342, a two-way cylinder 343, a connecting rod 344, and a plug rod 345.

[0059] There are two connecting blocks 341. The two connecting blocks 341 are arranged opposite each other on both sides of the fixed plate 2. The two connecting blocks 341 correspond one-to-one with the two connecting brackets 32, and the connecting blocks 341 face the connecting brackets 32. The connecting blocks 341 have insertion holes 3411 along the horizontal direction. The connecting seat 342 is fixedly installed at the end of the connecting frame 32 away from the lifting device 31. The bidirectional cylinder 343 is installed on the connecting seat 342, and the moving direction of the two output shafts of the bidirectional cylinder 343 is parallel to the axis of the insertion hole 3411. There are two connecting rods 344, which correspond one-to-one with the two output shafts of the bidirectional cylinder 343. The arrangement direction of the connecting rods 344 is perpendicular to the moving direction of the output shafts of the bidirectional cylinder 343. There are two insertion rods 345, which correspond one-to-one with the two connecting rods 344. The insertion rods 345 are fixedly installed on the connecting rods 344, and the arrangement direction of the insertion rods 345 is perpendicular to the arrangement direction of the connecting rods 344. The two insertion rods 345 are arranged opposite each other.

[0060] When it is necessary to connect the fixed plate 2 and the connecting frame 32, the bidirectional cylinder 343 is activated. The output shaft of the bidirectional cylinder 343 drives the two insertion rods 345 to move in a direction away from each other through the connecting rod 344. Then, the lifting device 31 drives the insertion rods 345 to move until the two insertion rods 345 are evenly inserted into the holes 3411 coaxially. The bidirectional cylinder 343 is activated again, and the connecting rod 344 drives the two insertion rods 345 to be inserted from both ends of the holes 3411 respectively, thereby realizing the hinge connection between the fixed plate 2 and the connecting frame 32.

[0061] Reference Figure 4 The bending member 33 is disposed on one of the lifting devices 31. The bending member 33 includes a telescopic device 331. In this embodiment, the telescopic device 331 is a cylinder, which is hinged to a nut in the lifting device 31. The output shaft of the cylinder is coaxially and fixedly connected to the connecting frame 32. Of course, in other optional embodiments, the telescopic device 331 can also be a structure with the function of extension and retraction. Moreover, in the connection structure between the cylinder and the connecting frame 32, the connecting frame 32 can also be omitted, and the connecting seat 342 can be directly installed on the output shaft of the cylinder.

[0062] It should be noted that the output shaft of the cylinder is arranged vertically upwards at an angle. Therefore, when the output shaft of the cylinder extends, the cylinder can drive the fixed plate 2 to rotate around the hinge at the other end through the connecting frame 32 and other components. At the same time as the fixed plate 2 rotates, the hole wall of the fixing hole 21 on the fixed plate 2 can apply a thrust to the reinforcing bar 5. Therefore, the bending member 33 achieves the bending effect of the reinforcing bar 5, and all the reinforcing bars 5 are bent at the same time, avoiding the situation where construction workers have to bend multiple reinforcing bars 5 one by one, thereby improving the work efficiency of construction workers.

[0063] In general, the bending member 33 in this embodiment is mainly a telescopic device 331. In other optional embodiments, the bending member 33 may also be other devices that can drive the fixed disk 2 to rotate.

[0064] Reference Figure 6 Multiple fasteners 4 are provided and are installed on the reinforcing bars 5. The number and position of the fasteners 4 on each reinforcing bar 5 are the same. In this embodiment, for ease of demonstration, two fasteners 4 are provided on each reinforcing bar 5, and the two fasteners 4 are evenly spaced along the length of the reinforcing bar 5. This is to minimize the impact of the fasteners 4 on the strength of the reinforcing bar 5, and the even spacing allows the fixing plate 2 to be stopped at any point on the reinforcing bar 5, and also provides some adjustment space for the position of the fixing plate 2. In other optional embodiments, the number of fasteners 4 can be determined according to the length of the reinforcing bar 5.

[0065] Reference Figure 7 The fixing component 4 includes a locking block 41 and a return spring 42.

[0066] A slot 51 for placing a locking block 41 is opened on the periphery of the reinforcing bar 5. The shape of the locking block 41 is adapted to the shape of the slot 51. The lower end of the locking block 41 is hinged to the slot wall of the slot 51. The return spring 42 is arranged horizontally. One end of the return spring 42 is fixedly connected to the locking block 41, and the other end of the return spring 42 is fixedly connected to the slot wall of the slot 51.

[0067] When the fixing plate 2 moves from below the reinforcing bar 5 to above the reinforcing bar 5, the wall of the fixing hole 21 on the fixing plate 2 will apply a pressure to the locking block 41 along the reinforcing bar 5. At this time, the locking block 41 rotates along its hinge into the locking groove 51, and the end face of the locking block 41 is flush with the peripheral wall of the reinforcing bar 5. The return spring 42 is in a compressed state. When the fixing plate 2 slides past the fixing member 4, the wall of the fixing hole 21 on the fixing plate 2 does not abut against the locking block 41. The return spring 42 returns to its original position and drives the locking block 41 to rotate in a direction away from the reinforcing bar 5. When the fixing plate 2 moves down again, the lower end face of the fixing plate 2 will abut against the upper end face of the locking block 41, and the locking block 41 will apply an upward supporting force to the fixing plate 2. Therefore, the fixing plate 2 cannot move down under the action of gravity or external force, and the fixing plate 2 is fixed at this point on the reinforcing bar 5.

[0068] The implementation principle of the high-altitude rapid positioning device for the main tower steel reinforcement skeleton in this application embodiment is as follows: In the initial state, three fixing plates 2 are stacked on the foundation steel reinforcement platform 1, and the fixing holes 21 on the three fixing plates 2 are connected from top to bottom. Then, the bidirectional cylinder 343 drives the insertion rod 345 to be inserted into the insertion hole 3411 of the connecting block 341 on the bottom fixing plate 2. Then, the lifting device 31 drives the bottom fixing plate 2 to move up a distance, thereby driving the three fixing plates 2 to move up a distance. Then, the steel bar 5 is inserted from the fixing hole 21 on the top fixing plate 2. One end of the steel bar 5 passes through the three fixing holes 21 and abuts against the foundation steel reinforcement platform 1. After all the steel bars 5 are inserted, one end of the steel bar 5 is fixed to the foundation steel reinforcement platform 1 by welding or casting. Then, the lifting and bending lifting component 3 moves the three fixing plates 2 down to the upper surface of the foundation steel reinforcement platform 1, and the bottom fixing plate 2 is fixed to the foundation steel reinforcement platform 1 by welding or other means.

[0069] Then, the bidirectional cylinder 343 is activated, which drives the insertion rod 345 to be pulled out from the insertion hole 3411 in the connecting block 341 on the bottom fixed plate 2. Then, the lifting device 31 drives the connecting piece 34 to move up to the top fixed plate 2. Then, the bidirectional cylinder 343 is activated again, which drives the insertion rod 345 to be inserted into the insertion hole 3411 in the connecting block 341 on the top fixed plate 2. At this time, since the lifting device 31 on the left side is hinged with the telescopic device 331, and the fixed plate 2 is not high at this time, the insertion rod 345 on the left connecting frame 32 can be manually aligned with the insertion hole 3411 so that the bidirectional cylinder 343 can drive the insertion rod 345 to be inserted into the insertion hole 3411. The uppermost fixed plate 2 is moved upward to the uppermost end of the reinforcing bar 5 by the lifting device 31, and is fixed to the uppermost end of the reinforcing bar 5 by the fixing member 4. Following the above process, the middle fixed plate 2 is then moved upward to the part of the reinforcing bar 5 that needs to be bent by the lifting device 31, and is fixed here by the fixing member 4. Then the output shaft of the drive cylinder (telescopic device 331) is extended, so that the insertion rod 345 applies an upward oblique thrust to the connecting block 341 on the fixed plate 2, thereby driving the fixed plate 2 to rotate around the hinge point between it and another insertion rod 345, thereby bending the reinforcing bar 5. At the same time, the fixed plate 2 bends all the reinforcing bars 5, which greatly simplifies the operation steps of bending the reinforcing bars 5, thereby improving the efficiency of the construction workers in bending the reinforcing bars 5 and speeding up the construction progress.

[0070] Moreover, this device ensures that all the reinforcing bars 5 have the same degree of bending, avoiding the need for later correction of the bending degree of the reinforcing bars 5. In addition, the fixing plate 2 can act as a horizontal fixing frame in this process, saving material costs. Furthermore, since the uppermost part of the reinforcing bars 5 may intersect due to different stresses after bending, which increases the difficulty of subsequent construction, the device also sets a fixing plate 2 at the highest point of the reinforcing bars 5, so that the uppermost part of the bent reinforcing bars 5 can also be evenly arranged, reducing the difficulty of construction and further improving the work efficiency of construction personnel.

[0071] This device is mainly used to build the entire steel reinforcement 5 skeleton. After the steel reinforcement 5 skeleton is built, it is necessary to seal the steel reinforcement 5 skeleton with plates and pour cement. In this device, the fixing plate 2 serves as the transverse steel reinforcement 5. Therefore, the fixing plate 2 is provided with multiple guide holes 22. The multiple guide holes 22 are evenly spaced around the axis of the fixing plate 2, and the multiple guide holes 22 are all located on the outside of the fixing hole 21. In this embodiment, each fixing plate 2 is provided with nine guide holes 22. In other optional embodiments, the number of guide holes 22 can be determined according to the size of the fixing plate 2.

[0072] Cement is usually poured from above the steel reinforcement 5 structure. Therefore, the setting of the guide hole 22 can accelerate the flow of cement in the steel reinforcement 5 structure and improve construction efficiency. Moreover, the uniform spacing of the nine guide holes 22 can make the cement distribution in the steel reinforcement 5 structure more uniform, thereby making the cement distribution of the entire main tower structure more uniform. As a result, the internal stress on each part of the main tower is also relatively uniform, which improves the load-bearing strength of the entire main tower.

[0073] 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.
