Description

Technical Field

[0001] The present application belongs to the technical field of steel structure bridges, and in particular relates to a bridge plate unit splicing device and a splicing method. Background Art

[0002] Steel structure bridges, that is, bridges whose main load-bearing structure is made of steel, are also called steel structure bridges or steel bridges. Because steel has high strength, the cross-section of steel structure bridge components can be relatively small and the deadweight is light under the same load-bearing capacity, so it is most suitable for building large-span bridges.

[0003] At present, the manufacturing process of steel structure bridges is mainly: parts → plate unit → segment assembly → segment bridge installation. In the process of double splicing of plate units and assembly of segment assemblies, before welding the plate unit butt welds, the plate units are leveled in pairs, and the misalignment must meet the requirements of the specification, generally not more than 1mm. The conventional situation is to separate the two sections of steel structure plates by a certain distance, and use the burning horse plate to forcibly level the adjacent plates in pairs, but the burning horse plate will damage the parent material. Another method is to adjust the steel plate by pressing heavy objects on the plate unit to make the adjacent plate units flat, but the weight pressing method is clumsy, and it takes a lot of energy to level the two plate units, which is very time-consuming and inconvenient to operate. Summary of the invention

[0004] The present application aims to at least to some extent solve the technical problem of how to quickly level adjacent structural panels. To this end, the present application provides a bridge plate unit splicing device and splicing method, which can quickly connect and level adjacent structural panels and effectively adjust the misalignment to less than or equal to 1 mm to meet construction requirements and ensure the quality of bridge construction.

[0014] In some embodiments, the spacing between adjacent lifting devices is greater than the spacing between adjacent adjusting members.

[0015] In some embodiments, a support plane frame is further included to support adjacent bridge deck units.

[0016] In a second aspect, an embodiment of the present application provides a method for splicing bridge plate units, which uses the above-mentioned bridge plate unit splicing device, and the splicing method includes:

[0017] At least two supporting jacking mechanisms are arranged at intervals at the locations to be spliced;

[0018] Place two bridge slab units opposite to each other, so that their opposite edges are placed on different supporting jacking mechanisms respectively, and the gap between the two bridge slab units meets the construction requirements;

[0020] The supporting jacking mechanism is adjusted on the first surface, and the adjusting member is adjusted on the second surface, so that the edges of adjacent bridge plate units are adjusted to have a misalignment amount until the misalignment amount is less than or equal to 1 mm.

[0032] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0033] Please refer to Figure 1 and Figure 2In a first aspect of the present application, a bridge plate unit 400 splicing device is provided, which is used for splicing adjacent bridge plate units 400. The bridge plate unit 400 includes a magnetic material. For example, the bridge plate unit 400 is a steel plate for a bridge. The bridge plate unit 400 has a first surface 401 and a second surface 402 opposite to each other. The bridge plate has a large area and can be deformed to a certain extent. The first surface 401 is the bottom surface of the steel plate, and the second surface 402 is the top surface of the steel plate. The device includes: at least two supporting jacking mechanisms 100 and a leveling mechanism 200. The number of supporting jacking mechanisms 100 can be determined according to needs. One supporting jacking mechanism 100 can be set corresponding to two adjacent bridge plate units 400, or each bridge plate unit can be set corresponding to a first supporting jacking mechanism 100. Corresponding to 400, a plurality of supporting and lifting mechanisms 100 are arranged corresponding to the same bridge plate unit 400, and the plurality of supporting and lifting mechanisms 100 corresponding to the same bridge plate unit 400 are arranged at intervals, and the supporting and lifting mechanisms 100 used to support two bridge plate units 400 are also arranged at intervals, and the plurality of supporting and lifting mechanisms 100 are respectively used to support the first surface 401 of adjacent bridge plate units 400 and adjust the height of adjacent bridge plate units 400, and the supporting and lifting mechanisms 100 play both a supporting role and a lifting role. For example, the supporting and lifting mechanism 100 is a jack, a lift or other device that can support and provide lifting, and the lift can lock the stroke so that the supporting and lifting mechanism 100 can still support the bridge plate unit 400 after adjusting the height.

[0034] The leveling mechanism 200 includes a connecting frame 210 and at least two adjusting members 220. The connecting frame 210 includes a fixed section 211 and an adjusting section 212. The fixed section 211 and the adjusting section 212 are respectively a local position on the connecting frame 210. Two fixed sections 211 are provided and are respectively located at the two ends of the connecting frame 210. The fixed section 211 is used for magnetic fixation with the adjacent second surface 402. The magnetic fixation can use a strong magnetic block or an electromagnet. The fixed section 211 is directly magnetically fixed to the magnetic material of the bridge plate unit 400, or is magnetically fixed to the bridge plate unit 400 through a binding magnet. After fixation, the connecting frame 210 spans across the adjacent bridge plate units 400, that is, the fixed sections 211 at the two ends of the connecting frame 210 correspond to a bridge plate unit 400 respectively, and the adjusting section 212 is spaced apart from the adjacent bridge plate unit 400. Located between the two fixed sections 211, the adjustment section 212 serves as the basis for installing the adjustment member 220; multiple adjustment members 220 are all connected to the adjustment section 212, and the adjustment member 220 is set as a rod. The adjustment section 212 is provided with a groove or hole matching therewith, so that the adjustment member 220 can match the adjustment section 212, and the ends of multiple adjustment members 220 are respectively used to abut against adjacent bridge plate units 400. As shown in the figure, the bottom end of the adjustment member 220 abuts against the second surface 402, and the height of the adjustment member 220 is adjustable relative to the adjustment section 212. For example, the adjustment member 220 is threadedly connected to the adjustment section 212, and the position of the adjustment member 220 can be moved up and down by rotation, so that the end of the adjustment member 220 acts on the adjacent second surface 402, and the adjustment member 220 applies a force to the bridge plate unit 400, thereby changing the edge height of the bridge plate unit 400.

[0035] The prior art uses burning horse plates or ballast weights to level adjacent plates of a bridge, but burning horse plates will damage the base material of the bridge, and ballast weights cannot level the bridge quickly. Currently, there is a lack of devices that can quickly level adjacent structural plates of a bridge. The present application supports the bridge plate unit 400 through the supporting jacking mechanism 100 and adjusts its height, so that it can be adjusted on the first surface 401 of the bridge plate unit 400, and then the adjacent bridge plate unit 400 is adjusted on the second surface 402 by the leveling mechanism 200. Specifically, the two bridge plate units 400 are respectively connected and fixed by the fixing section 211, and are firmly connected by magnetic attraction. Then, the adjusting section 212 provides support for the adjusting member 220, so that the adjusting member 220 can abut the bridge plate unit 400 on the second surface 402, and the height can be adjusted relative to the adjusting section 212 by multiple adjusting members 220. The end of the adjusting member 220 can apply a force to the bridge plate unit 400, that is, the height of the edge of the bridge plate unit 400 can be adjusted, so as to level the edges of the adjacent bridge plate units 400, so that the adjacent structural panels can be quickly connected and leveled to meet the construction requirements.

[0036] Please refer to Figure 2 In some embodiments, the adjusting member 220 is threadedly connected to the adjusting section 212, the adjusting section 212 is located in the middle of the connecting frame 210, and the adjusting section 212 is provided with two spaced threaded holes, and the two threaded holes correspond to the edges of two adjacent steel plates respectively. The adjusting member 220 adopts a screw rod, and the adjusting member 220 acts on the second surface 402 along the extension direction of the thread, that is, the screw rod is perpendicular to the second surface 402. By rotating the screw rod, the end of the screw rod abuts and acts on the steel plate to adjust the height of the bridge plate unit 400. In some embodiments, the leveling mechanism 200 also includes a locking piece 230, which is a nut. The locking piece 230 is connected to the adjusting piece 220, such as a nut and a screw thread matching connection. The locking piece 230 is used to lock the relative position of the adjusting piece 220 and the adjusting section 212. After the screw position is adjusted, if it is subjected to the force of the steel plate, it may rotate and adjust the screw in the opposite direction. After adding the locking piece 230, the screw can be locked, and a slot can be opened in the adjusting section 212 to allow the nut to be placed in the slot. In some embodiments, the connecting frame 210 also includes a transition section 213, at least two transition sections 213 are respectively connected to the two ends of the adjustment section 212, the transition section 213 is tilted, the adjustment section 212 is horizontally set, and both ends of the adjustment section 212 are connected to a transition section 213, the two transition sections 213 are symmetrically set, and the transition sections 213 are connected to the fixed sections 211 one by one. The adjustment section 212, the transition section 213 and the fixed section 211 can be an integrally formed steel member, and the transition section 213, the adjustment section 212 and the magnetic device 240 are located on the same side of the fixed section 211.

[0037] In some embodiments, the leveling mechanism 200 also includes at least two magnetic devices 240, which are respectively fixed to the connecting frame 210. The magnetic device 240 is a permanent magnet. The size of the permanent magnet must be designed to be able to generate sufficient magnetic attraction to ensure the stability of the magnetic attraction between the connecting frame 210 and the steel plate. The magnetic device 240 can also be an electromagnet that can generate a strong magnetic attraction when powered on, and the parameters such as the number of coil turns, the size of the electromagnet, and the number of electromagnets are used to ensure that the magnetic device 240 can generate sufficient magnetic force to be firmly magnetically attracted to the steel plate; some of the magnetic devices 240 are used to magnetically attract one of the adjacent bridge plate units 400, and the other part of the magnetic devices 240 are used to magnetically attract the other of the adjacent bridge plate units 400. If a permanent magnet is used, the size of the permanent magnet meets the magnetic attraction requirement. If an electromagnet is used, the coil of the electromagnet is connected to a power supply, and whether it is powered on can be controlled. The magnetic attraction of the electromagnet to the steel plate is achieved by controlling the power-on state of the electromagnet, and each steel plate can correspond to at least one magnetic device 240. In some embodiments, the leveling mechanism 200 further includes a fixing member 250, which connects and fixes the magnetic device 240 to the fixing section 211, such as an ear seat with a through hole protruding from the bottom of the fixing section 211 of the connecting frame 210, and a through hole is provided at the top of the magnetic device 240, and the fixing member 250 uses a pin, and the magnetic device 240 is connected to the fixing section 211 to form a whole by passing the pin through the through hole. In an optional embodiment, the second surface 402 of the steel plate is provided with a U-shaped rib 410, and the spacing between the magnetic devices 240 for magnetically attracting adjacent steel plates is equal to the spacing between the U-shaped ribs 410 on the two steel plates near the joint, so that the magnetic device 240 can be magnetically attracted to the protruding position of the U-shaped rib 410 and can be regarded as a whole with the steel plate.

[0038] In some embodiments, the support jacking mechanism 100 includes a support column 110 and a jacking device 120. The support column 110 is used to be fixed at the interval of the first surface 401. The support column 110 adopts a steel column or other column structure. The bottom end of the support column 110 can be fixed to the ground of the working area by bolts. The jacking device 120 is fixed to the support column 110. For example, the jacking device 120 is placed on the top surface of the support column 110. The jacking device 120 can also be fixed to the support column 110 by screws. The jacking device 120 is used to abut and act on the first surface 401. If the jacking device 120 adopts a jack, the top of the jack column abuts against the edge of the steel plate. At least one support jacking mechanism 100 corresponds to a steel plate, and is spaced between the jacks acting on two adjacent steel plates, and is respectively located on both sides of the splicing seam. In some embodiments, the spacing between adjacent lifting devices 120 is greater than the spacing between adjacent adjusting members 220, and the jack has a stronger lifting effect on the bridge plate unit 400, while the force that the adjusting member 220 can exert is less than the force of the jack. By setting the above spacing, the height adjustment of the two steel plates can be more easily achieved. When the misalignment of the adjacent bridge plate units 400 does not meet the requirements, the flatness of the two is adjusted by the jack and the screw. For example, if the steel plate on the left side of the plate seam is higher than the reference plane, start the left screw, and use the screw to press the left steel plate downward to adjust it to a suitable plane, and the same is true for the right side; when the steel plate on the left side of the plate seam is lower than the reference plane, start the left jack, and adjust the jack to push the left steel plate upward to adjust it to a suitable plane, and the same is true for the right side.

[0039] In some embodiments, the device also includes a supporting plane frame 300, which is used to support adjacent bridge plate units 400. The top of the supporting plane frame 300 is a flat surface, which is convenient for placing the bridge plate units 400. The supporting plane frame 300 can adopt a frame or frame structure. Two supporting plane frames 300 can be used, each corresponding to a bridge plate unit 400, and the two supporting plane frames 300 are arranged at intervals. When the bridge plate unit 400 is placed on the supporting plane frame 300, the two bridge plate units 400 are in a horizontal state and the two are roughly flush. For example, the steel plates are spliced ​​and placed, and there are splicing seams between the steel plates. The above-mentioned lifting device 120 and the adjusting member 220 are used to adjust the height of the edge of the steel plate to achieve flatness adjustment so that the misalignment meets the requirements.

[0040] In a second aspect of the present application, a method for splicing a bridge plate unit 400 is provided, which uses the above-mentioned bridge plate unit 400 splicing device, and the splicing method includes:

[0041] S1. Set at least two supporting jacking mechanisms 100 at intervals at the place to be spliced. The place to be spliced ​​is the place where the edges of two adjacent bridge plate units 400 are opposite to each other. The supporting plane frame 300 can be placed in the construction area first, and then the two bridge plate units 400 can be hoisted onto the supporting plane frame 300 in turn.

[0042] S2. Place two bridge plate units 400 opposite to each other so that their relative edges are placed on different supporting jacking mechanisms 100 respectively, and the plate seam gap between the two bridge plate units 400 meets the construction requirements. For example, the edge of the butt joint of the steel plate is pressed on the end of the shaft rod of the jack. After the two steel plates are placed opposite to each other, the gap between them meets the construction requirements.

[0043] S3. Fix the two ends of the connecting frame 210 to the adjacent bridge plate units 400 respectively, such as by magnetically attracting the two ends of the connecting frame 210 to the steel plate through permanent magnets, or by energizing the two ends of the connecting frame 210 through electromagnets to generate magnetic attraction with the steel plate, so that the two ends of the connecting frame 210 are relatively fixed to the steel plate, and the adjusting section 212 is spaced apart from the steel plate, and can abut against the steel plate through the adjusting member 220.

[0044] S4. Adjust the supporting lifting mechanism 100 on the first surface 401, such as by adjusting the jack to adjust the height of the edge of the bridge plate unit 400 by utilizing the lifting effect, and adjust the adjusting member 220 on the second surface 402 to move the position of the adjusting member 220 relative to the adjusting section 212, so that the adjusting member 220 also changes its height, and then acts downward on the edge of the bridge plate unit 400 through the action force between the end of the adjusting member 220 and the bridge plate unit 400, so that the edges of adjacent bridge plate units 400 are adjusted to have misaligned amounts until the upper and lower misaligned amounts are less than or equal to 1 mm, meeting the requirements of the specification.

[0045] The prior art adopts burning horse plates or pressing weights to level the adjacent plates of the bridge, but the burning horse plates will damage the base material of the bridge, and the pressing weights cannot be quickly leveled. Currently, there is a lack of methods that can quickly level the adjacent structural plates of the bridge. The present application places the supporting jacking mechanism 100 at the place to be spliced ​​to provide support for the edges of the adjacent bridge plate units 400, fixes the bridge plate units 400 with the connecting frame 210, and can provide a basis for the adjustment member 220 to apply force, and then adjusts the edge height of the bridge plate unit 400 on the first surface 401 through the supporting jacking mechanism 100, and adjusts the edge height of the bridge plate unit 400 on the second surface 402 through the adjustment member 220, so that the edge height of the bridge plate unit 400 is adjusted from both sides of the bridge plate unit 400 at the same time, and the adjacent bridge plate units 400 are quickly leveled by cooperation, so as to achieve the effect of codeless assembly, and effectively adjust the upper and lower misalignment to less than or equal to 1mm, so that the bridge plate unit 400 meets the construction requirements, thereby effectively ensuring the quality of the bridge.
