Abstract
Description
Technical Field
[0001] This application relates to the technical field of building construction, and in particular to a large-span pedestrian walkway structure along a street. Background Technology
[0002] To meet the architectural functional requirements between two high-rise towers, connecting corridors are often used to form a connected structure.
[0003] In existing technologies, the installation of connecting corridors involves pre-positioning the area on the tower using a laser projector to determine the corresponding installation zone. The existing connecting corridor structure typically includes a base slab, a top slab, chords on both sides of the base and top slabs, web members fixed between two chords on the same side, and pre-installed pipes on the tower to connect the chords. After the connecting corridor is assembled on the ground, workers test the hydraulic lifting system. This system uses steel strands connected to lifting points on the top slab to lift the corridor. Once the ends of the chords and the corresponding pre-installed pipes are aligned, workers weld them together using a welding torch, thus successfully installing the connecting corridor.
[0004] Since the connecting corridor is installed between two towers, the settlement of the two towers at different heights will be different, resulting in a height difference of several centimeters between the pre-installed pipes that should be aligned on each tower. Workers can solve the height difference problem by adjusting the lifting height at both ends of the connecting corridor using a hydraulic lifting system. However, during the height adjustment of the connecting corridor, workers need to frequently observe the connection between the chord pipes and the pre-installed pipes, which greatly increases the workload and working time of the workers, as well as the safety hazards when working at height. Therefore, further improvements are needed. Summary of the Invention
[0005] In order to reduce the connection time between the chord tubes and the pre-installed tubes, thereby reducing the workload of workers and the safety hazards of working at heights, this application provides a long-span connecting corridor structure along the street.
[0006] This application provides a large-span pedestrian walkway structure along a street, employing the following technical solution:
[0007] A long-span pedestrian walkway structure along a street includes a base slab, a top slab above the base slab, chord tubes on both sides of the base slab and the top slab, web members fixedly connected between two chord tubes on the same side, and pre-installed tubes pre-mounted on a tower for connection with the chord tubes. The pre-installed tubes have a first slot on their end face near the chord tubes, and the chord tubes have a second slot opposite to the first slot. The pre-installed tubes are equipped with a docking mechanism for connecting with the chord tubes. The docking mechanism includes a docking block built into the first slot and a pushing assembly for inserting the docking block into the first and second slots. The pushing assembly includes a pushing cloth inserted into the first slot, a first limiting member restricting movement at one end of the pushing cloth, and an unlocking member located on the first limiting member to unlock the pushing cloth and disengage it from the first slot. The pushing cloth is located between the inner wall of the first slot and the docking block, with its upper end exposed outside the first slot. The surface of the docking block near the second slot has a first guide surface.
[0008] By adopting the above technical solution, before the connecting corridor is raised to the point where the chord tube and the pre-installed tube are connected, the connecting block and the push cloth are first inserted into the first slot. When the chord tube at one end is raised to the point where it is close to the pre-installed tube by the hydraulic lifting system, since the surface of the connecting block near the second slot is provided with a first guide surface, by pulling the upper end of the push cloth, since the movement of one end of the push cloth is restricted by the first limiting member, when the push cloth is pulled, the connecting block moves towards the direction of the second slot. At this time, the first guide surface provided on the connecting block is first inserted into the second slot.
[0009] When the first guide surface is inserted into the second slot to align the chord tube and the pre-assembled tube, the hydraulic lifting system that was lifting one end of the chord tube can be stopped, and the pusher cloth can be pulled to continue pushing the docking block to insert the docking block into the first and second slots. Then, the end of the pusher cloth that was restricted can be unlocked by the unlocking device to disengage it from the first slot, so as to reduce the impact on the subsequent welding between the chord tube and the pre-assembled tube, so as to install the chord tube and the pre-assembled tube.
[0010] Therefore, by setting up a docking block and a jacking assembly, the docking between the pre-installed pipe and the chord pipe can be accelerated, the docking time between the chord pipe and the pre-installed pipe can be reduced, thereby reducing the workload of workers and the safety hazards during high-altitude operations, and the connection strength between the two can be improved.
[0011] Preferably, the first limiting member is a limiting plate disposed between the docking block and the inner bottom wall of the first slot, the limiting plate having a through groove, the pushing cloth passing through the through groove and abutting against the surfaces of the docking block and the limiting plate respectively; the unlocking member includes an unlocking plate inserted into the inner bottom wall of the first guide surface and the first slot, the unlocking plate being disposed on the limiting plate, the unlocking plate having a second guide surface abutting against the first guide surface, and the through groove being disposed close to the unlocking plate.
[0012] By adopting the above technical solution, before inserting the docking block into the first slot, the pushing cloth is first wrapped around the end of the docking block away from the first guide surface. The lower end of the pushing cloth is then inserted through a groove and abuts against the surfaces of the limiting plate and the docking block that are close to each other. Then, the pushing cloth is inserted into the first slot along with the docking block. During the process of fully inserting into the first slot, the limiting plate is also brought into the first slot to restrict the movement of one end of the pushing cloth; and the unlocking plate is driven into the first slot to abut against the first guide surface. Since the unlocking plate has a second guide surface that abuts against the first guide surface, the cross-sectional area of the unlocking plate gradually increases in the direction away from the limiting plate. When the second guide surface abuts against the first guide surface, the docking block is restricted, thereby reducing the possibility of the docking block falling before being inserted into the second slot, that is, reducing the possibility of objects falling from a height.
[0013] Because the first guide surface and the second guide surface abut each other, when the push cloth is pulled, the unlocking plate can be moved away from the first slot, so that the end that restricts the movement of the push cloth can also be moved closer to the second slot. Together, the docking block is pushed closer to the second slot so that the docking block is inserted into the second slot. It should be noted that when the unlocking plate is not completely detached from the first slot, the limiting plate is still located on the inner bottom wall of the docking block and the first slot, and can also limit the push cloth, so that the docking block continues to be inserted into the first slot during the process of pulling the push cloth. When the push cloth is pulled again, when the unlocking plate is completely detached from the first slot, the through groove opened on the limiting plate is exposed to the outside, so that when the push cloth is pulled again, the push cloth can be detached from the first slot for recycling and reuse. Then, welding is started between the pre-assembled tube, the chord tube and the docking block.
[0014] Preferably, the unlocking component further includes a connecting plate disposed on the end face of the unlocking plate away from the limiting plate, the connecting plate being exposed in the first slot and bent toward the lower surface of the pre-installed tube.
[0015] By adopting the above technical solution, due to the small distance between the pre-installed tube and the chord tube, the unlocking plate may enter the second slot along with the connecting block during the process of pushing the connecting block towards the second slot, potentially increasing the docking time between the chord tube and the pre-installed tube. However, by providing a connecting plate, which is bent, the unlocking plate can be moved away from the first and second slots during the process of pushing the connecting block into the second slot. This reduces the possibility of the unlocking plate entering the second slot along with the connecting block, thereby reducing the docking time between the chord tube and the pre-installed tube, thus reducing the workload of workers, safety hazards during high-altitude operations, and the impact of subsequent welding between the two.
[0016] Preferably, the upper surface of the limiting plate is provided with an elastic element.
[0017] By adopting the above technical solution and by setting up elastic elements to fill the gap between the limiting plate, the docking block, and the bottom of the first slot, the pusher cloth can be subjected to the pressure of the docking block to increase the friction between the pusher cloth, the limiting plate, and the docking block, thereby reducing the possibility of failing to push the docking block when the pusher cloth is pulled, and also improving the limiting effect of the docking block, further reducing the possibility of slipping out of the first slot and causing objects to fall from a height.
[0018] Preferably, the pushing assembly further includes a driving component for winding the pushing cloth to push the docking block to slide. The driving component includes a winding rod for winding the pushing cloth and a handwheel for driving the winding rod to rotate. The length direction of the winding rod is perpendicular to the length direction of the pre-installed tube, and two pushing cloths located on the same side are wound around one winding rod.
[0019] By adopting the above technical solution, the manual pulling of the pusher cloth can lead to instability during the pushing of the connecting block if the force is uneven, thus prolonging the connection time between the chord tube and the precast tube. The addition of a winding rod and handwheel addresses this issue. Turning the handwheel drives the winding rod, which in turn winds up the pusher cloth, resulting in more even force application and improved stability during the pushing process. Furthermore, by winding two pusher cloths located on the same side onto a single winding rod, both cloths can be wound up at once when the handwheel is turned, indirectly accelerating the connection speed between the precast tube and the connecting block, thereby reducing the workload of workers and safety hazards during high-altitude operations.
[0020] Preferably, the unlocking component further includes a connecting rope fixedly connected to the connecting plate, the connecting rope being fixedly connected to the winding rod and wound around the winding rod.
[0021] By adopting the above technical solution, and by setting a connecting rope that connects to the connecting plate and the coil rod, the connecting plate can drive the unlocking plate to slide away from the first slot and suspend it in the air together with the connecting rope, which is convenient for storage and reduces the possibility of objects falling from a height.
[0022] Preferably, the jacking assembly further includes a mounting bracket for mounting the drive component, the drive component being detachably connected to the pre-installed tube via the mounting bracket, and the coil rod being rotatably inserted through the mounting bracket.
[0023] By adopting the above technical solution, since the mounting bracket is provided, the drive unit can be installed on the pre-installed tube so that the handwheel can be applied to drive the roll-up of the push cloth. After the docking block is inserted into the first slot and the second slot, it can also be removed from the pre-installed tube for subsequent use.
[0024] Preferably, the mounting frame includes two first mounting plates coaxially sleeved on the roll rod and a second mounting plate disposed between the two first mounting plates. The two first mounting plates are respectively disposed on both sides of the push cloth, and the second mounting plate is a magnetic plate that is magnetically attracted to the pre-installed tube.
[0025] By adopting the above technical solution, the second mounting plate is set as a magnetic suction plate so that the driving component can be installed on the pre-installed pipe. In addition, by selecting the second mounting plate as a magnetic suction plate, the possibility of excessive magnetic attraction of the overall mounting frame affecting the use of other pipe fittings or tools made of rigid materials can be reduced.
[0026] Preferably, the winding rod includes a first winding rod and two second winding rods slidably connected to both ends of the first winding rod. The second winding rods are provided with a second limiting member to restrict the sliding of the first winding rod. The pushing cloth is wound around the second winding rods. A mounting sleeve is coaxially sleeved in the middle of the first winding rod. A first bevel gear is coaxially sleeved in the mounting sleeve. The axis of the handwheel is perpendicular to the axis of the mounting sleeve. The handwheel rotates through the mounting sleeve. The handwheel is coaxially connected to a second bevel gear, and the second bevel gear meshes with the first bevel gear.
[0027] By adopting the above technical solution, and by setting a first roller rod, a second roller rod slidably connected to both ends of the first roller rod, and a second limiting member, the spacing between the two top-pushing cloths can be adjusted according to the width between the pre-installed pipes corresponding to different widths of the connecting corridor, so as to improve the adaptability of the driving component.
[0028] In summary, this application has the following beneficial effects:
[0029] 1. By setting up a docking block and a jacking component, the docking between the pre-installed pipe and the chord pipe can be accelerated, reducing the docking time between the chord pipe and the pre-installed pipe, thereby reducing the workload of workers and the safety hazards during high-altitude operations, and improving the connection strength between the two.
[0030] 2. By setting up a rolling rod and a handwheel, and winding two top-pushing cloths located on the same side onto a single rolling rod, the two top-pushing cloths can be rolled up at once when the handwheel is turned, which indirectly speeds up the docking rate between the precast pipe and the docking block, thereby reducing the workload of workers and the safety hazards during high-altitude operations.
[0031] 3. By providing a mounting bracket, the drive unit can be installed on the pre-installed tube so that force can be applied to the handwheel to drive the roll-up of the push cloth, so that the docking block can be inserted into the first slot and the second slot. It can also be removed from the pre-installed tube for subsequent use. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail below.
[0041] This application discloses a large-span pedestrian walkway structure along a street.
[0042] Example:
[0043] A large-span pedestrian walkway structure along the street, referring to Figure 1 , Figure 2 The system includes a horizontally arranged base slab 1, a horizontally arranged top slab 11 directly above the base slab 1, horizontal chord tubes 12 welded to both sides of the base slab 1 and the top slab 11, web members 13 welded between two chord tubes 12 on the same side, and pre-installed pipes 2 pre-fixed on the tower for connection with the chord tubes 12. The cross-sections of both the chord tubes 12 and the pre-installed pipes 2 are square-ring shaped. After the connecting corridor is assembled on the ground, workers install and debug the hydraulic lifting system. The hydraulic lifting system simultaneously lifts both ends of the connecting corridor. Once the ends of the chord tubes 12 and the corresponding pre-installed pipes 2 are aligned, workers weld the chord tubes 12 and pre-installed pipes 2 together using a welding torch, thus successfully installing the connecting corridor.
[0044] It should be noted that the hydraulic lifting system mainly consists of three parts: a lifting platform installed on the tower, a hydraulic lifter installed on the lifting platform, and steel strands connecting the hydraulic lifter and the end of the chord tube 12. It is a common device in the process of lifting the connecting corridor, so this application will not describe it in detail.
[0045] Reference Figure 2 , Figure 3The pre-installed tube 2 has a first slot 21 on its end face near the chord tube 12, and the chord tube 12 has a second slot 121 opposite to the first slot 21. The pre-installed tube 2 is provided with a docking mechanism 3 for docking with the chord tube 12. Specifically, the docking mechanism 3 includes a docking block 4 built into the first slot 21 and a pusher component 5 that pushes the docking block 4 into the first slot 21 and the second slot 121. In this embodiment, the surface of the docking block 4 near the second slot 121 is provided with a first guide surface 41. During the lifting process of the connecting corridor, the pusher component 5 pushes the docking block 4 into the second slot 121. The first guide surface 41 on the docking block 4 can dock the pre-installed tube 2 and the chord tube 12.
[0046] Specifically, the push assembly 5 includes a push cloth 51 inserted into the first slot 21, a first limiting member 52 restricting the movement of one end of the push cloth 51, an unlocking member 53 disposed on the first limiting member 52 to unlock the push cloth 51 and disengage it from the first slot 21, a drive member 6 disposed on the pre-installed tube 2 to roll up the push cloth 51 to push the docking block 4 to slide, and a mounting bracket 54 for mounting the drive member 6.
[0047] Reference Figure 3 , Figure 4 In this embodiment, the pusher 51 is disposed between the inner wall of the first slot 21 and the docking block 4. The upper end of the pusher 51 is exposed outside the first slot 21, and the lower end of the pusher 51 is restricted by a limiting member. In this embodiment, the first limiting member 52 is a limiting plate disposed between the docking block 4 and the inner bottom wall of the first slot 21. A through groove 521 is provided through the limiting plate. The lower end of the pusher 51 passes through the through groove 521 and abuts against the surfaces of the docking block 4 and the limiting plate that are close to each other.
[0048] It should be noted that the lower end of the pusher cloth 51 is positioned away from the inner wall of the first slot 21, in a Z-shape, and exposed in the first slot 21; or the lower end of the pusher cloth 51 can be folded into a C-shape after passing through the through slot 521, as shown. Figure 5 As shown, in this embodiment, the lower end of the pusher cloth 51 is positioned away from the inner wall of the first slot 21.
[0049] It should be noted that, for the installation of the docking block 4 and the push cloth 51, before inserting the docking block 4 into the first slot 21, the push cloth 51 is first wrapped around the end of the docking block 4 away from the first guide surface 41, and the lower end of the push cloth 51 is passed through the through groove 521 and then abuts against the surfaces of the limiting plate and the docking block 4 that are close to each other, and then inserted into the first slot 21 together, thereby installing the docking block 4 and the push cloth 51 into the first slot 21.
[0050] Furthermore, an elastic element 522 is provided on the upper surface of the limiting plate. In this embodiment, the elastic element 522 is an elastic pad to fill the gap between the limiting plate, the docking block 4, and the bottom of the first slot 21, thereby reducing the possibility that the docking block 4 may fail to be pushed when the push cloth 51 is pulled.
[0051] The unlocking component 53 includes an unlocking plate 531 inserted into the inner bottom wall of the first guide surface 41 and the first slot 21, a connecting plate 532 fixedly connected to the end face of the unlocking plate 531 away from the limiting plate, and a connecting rope 533 fixedly connected to the connecting plate 532. The unlocking plate 531 is fixedly connected to the limiting plate and has a second guide surface 7 that abuts against the first guide surface 41. It should be noted that the through slot 521 is located close to the unlocking plate 531. The connecting plate 532 is exposed in the first slot 21 and is bent towards the lower surface of the pre-installed tube 2. This reduces the possibility that the unlocking plate 531 will enter the second slot 121 along with the docking block 4 when the docking block 4 is pushed towards the second slot 121. The connecting rope 533 is exposed in the first slot 21. The other end of the connecting rope 533 is set in the drive member 6. When the drive member 6 is activated, the connecting rope 533 can be wound up to reduce the possibility of objects falling from the height of the connecting plate 532, the unlocking plate 531 and the limiting plate.
[0052] Reference Figure 6 The driving component 6 includes a winding rod 61 for the push cloth 51 to be wound around and a handwheel 62 for driving the winding rod 61 to rotate. In this embodiment, the length direction of the winding rod 61 is perpendicular to the length direction of the pre-installed tube 2, and the two push cloths 51 located on the same side are wound around one winding rod 61.
[0053] Reference Figure 6 , Figure 7 Specifically, to accommodate pre-installed tubes 2 with different spacing, the coil 61 includes a first coil 611, two second coils 612 respectively slidably connected to both ends of the first coil 611, and a second limiting member 613 restricting the sliding of the first coil 611. The pusher cloth 51 is wound around the second coil 612. The end face of the second coil 612 is provided with a sliding groove 8 for the first coil 611 to slide and connect. The second coil 612 is provided with a limiting groove (not shown in the figure) symmetrically opened along the axis on the inner wall of the sliding groove 8. The outer peripheral wall of the first coil 611 is provided with a limiting block (not shown in the figure). The limiting block is slidably connected to the limiting groove so that the second coil 612 and the first coil 611 can rotate coaxially.
[0054] The second limiting member 613 is a limiting bolt. The second coil rod 612 has a through hole 9 for the limiting bolt to pass through. The first coil rod 611 has several threaded holes 10 along its length. The limiting bolt passes through the through hole 9 and is threadedly connected to the threaded hole 10 to limit the slippage of the second coil rod 612.
[0055] At this time, handwheel 62 is located in the middle of the first winding rod 611. A mounting sleeve 63 is coaxially fitted in the middle of the first winding rod 611. A first bevel gear 64 is coaxially fitted inside the mounting sleeve 63. The axis of handwheel 62 is perpendicular to the axis of the mounting sleeve 63. Handwheel 62 rotates through the mounting sleeve 63. A second bevel gear 621 is coaxially connected to handwheel 62, and the second bevel gear 621 meshes with the first bevel gear 64. Rotating handwheel 62 sequentially drives the second bevel gear 621, the first bevel gear 64, and the first winding rod 611 to rotate, thereby pushing the top-pushing cloth 51 to rewind, thus pushing the connecting block 4 into the second slot 121. The connecting rope 533 is fixedly connected to and wound around the second winding rod 612.
[0056] Back Figure 2 , Figure 3 In this embodiment, the drive component 6 is detachably connected to the pre-installed tube 2 via the mounting bracket 54. The coil rod 61 is rotatably inserted through the mounting bracket 54. Specifically, the mounting bracket 54 includes two first mounting plates 541 coaxially sleeved on the first coil rod 611 and a second mounting plate 542 disposed between the two first mounting plates 541. The two first mounting plates 541 are respectively disposed on both sides of the push cloth 51. The second mounting plate 542 is a magnetic plate and is magnetically attached to the pre-installed tube 2. The first coil rod 611 is rotatably inserted through the first mounting plate 541.
[0057] The implementation principle of a long-span connecting corridor structure along the street in this application embodiment is as follows: Before the connecting corridor is lifted to the point where the chord tube 12 and the pre-installed tube 2 are connected, the connecting block 4 and the push cloth 51 are first inserted into the first slot 21. When the chord tube 12 at one end is lifted to the point where it is close to the pre-installed tube 2 by the hydraulic lifting system, since the surface of the connecting block 4 near the second slot 121 is provided with a first guide surface 41, the upper end of the push cloth 51 is pulled by rotating the handwheel 62. Since the movement of one end of the push cloth 51 is restricted by the first limiting member 52, when the push cloth 51 is pulled, the connecting block 4 moves toward the direction close to the second slot 121. At this time, the first guide surface 41 provided on the connecting block 4 is first inserted into the second slot 121.
[0058] When the first guide surface 41 is inserted into the second slot 121, it connects the string tube 12 and the pre-installed tube 2. At this time, the hydraulic lifting system that lifts one end of the string tube 12 can be stopped from lifting the string tube 12. Continue to turn the handwheel 62 to pull the push cloth 51, thereby continuing to push the docking block 4 to insert the docking block 4 into the first slot 21 and the second slot 121. As the docking block 4 is inserted into the second slot 121, it drives the unlocking plate 531 to move away from the first slot 21. When the unlocking plate 531 is completely disengaged from the first slot 21, the through groove 521 opened on the limit plate is exposed to the outside. This allows the push cloth 51 to be disengaged from the first slot 21 when the handwheel 62 is turned again, so that the push cloth 51 can be recycled for the next use. Then, welding is started between the pre-installed tube 2, the string tube 12 and the docking block 4.
[0059] 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.
