Description

Technical Field

[0001] This utility model relates to the field of precast cap beam support technology, specifically to a transport support device for precast cap beams with large cantilever arms. Background Technology

[0002] Prefabricated bridges offer numerous advantages over traditional bridge construction methods, aligning with my country's commitment to resource conservation and environmental protection, and representing a major trend for the sustainable development of my country's bridge construction industry. However, individual prefabricated cap beams are large and difficult to transport. To facilitate construction, they are often prefabricated in two sections, with a 2-meter-wide cast-in-place section reserved for later casting. The significant height difference between the top of the pier and the cantilever end of the half-prefabricated large cantilever cap beam makes it highly susceptible to instability during transportation, posing a risk of overturning and significant safety hazards. Utility Model Content

[0003] This utility model provides a transport support device for precast cap beams with large cantilever arms, which can overcome some or all the defects of the prior art.

[0004] According to the present invention, a large cantilever precast cap beam transportation support device includes a device body, the device body including a base located on the floor of the transport vehicle, and a support component located on the base corresponding to the fulcrum position of the precast cap beam. The support component is used to provide support for the fulcrum position of the precast cap beam; wherein, the slope of the top of the support component matches that of the bottom surface of the cap beam.

[0005] The present invention discloses a transport support device for precast cap beams with large cantilever arms. By supporting the support components at the fulcrum of the precast cap beams, the weight of the cap beams can be effectively distributed, avoiding the center of gravity shift caused by weight concentration. This reduces the possibility of the cap beams overturning due to swaying or bumping during transportation, eliminates a huge safety hazard, and ensures the safety of personnel and equipment during transportation.

[0006] Understandably, by matching the slope of the top of the support component with that of the bottom of the cap beam, the support component and the bottom of the cap beam have a larger contact area, which not only improves the connection stability between the support component and the bottom of the cap beam, but also does not cause any appearance damage to the precast cap beam.

[0007] Preferably, the support assembly includes two sets of base plates located on the top wall of the base, each base plate having a support pipe along its vertical direction, and each support pipe having a top plate formed at its top wall that matches the slope of the bottom surface of the cap beam.

[0008] By setting support pipes vertically along the base plate, stable vertical support can be provided for the precast cap beam. The top plate formed at the top wall of the support pipe matches the slope of the bottom surface of the cap beam, so that the support components can fit in close contact with the bottom surface of the cap beam. This not only provides uniform support force and avoids damage to the cap beam due to uneven local stress, but also better adapts to the height difference between the top of the pier and the end of the cantilever precast cap beam, further improving the stability and reliability of the support.

[0009] Preferably, each support tube has a filling cavity, and the top plate has a circular hole communicating with the filling cavity, which is filled with fine sand.

[0010] Internal sand filling helps enhance the overall stability of the support pipe, enabling it to more effectively bear the weight of the cap beam and reducing the possibility of deformation or damage to the support pipe.

[0011] Preferably, a rubber pad is provided at the top plate.

[0012] The rubber pads protect the surface of the precast cap beam, preventing damage to its appearance. Furthermore, the roughness of the rubber pads increases friction between the top slab and the bottom of the cap beam, improving its stability during transport.

[0013] Preferably, multiple stiffening plates are provided between the support pipe and the bottom plate, as well as between the top plate and the support pipe.

[0014] By adding stiffening plates, the overall rigidity of the support pipe can be increased, enabling it to support the precast cap beam more reliably.

[0015] Preferably, multiple lifting lugs are provided on the outer wall of the support tube.

[0016] The above structure provides a reliable connection point for hoisting equipment (such as cranes), facilitating the hoisting and disassembly of this device.

[0017] Preferably, a connecting piece is provided between the two sets of base plates and the base.

[0018] Connecting the two sets of base plates to the base with connectors can enhance the overall structural strength of the device.

[0019] This device is composed of steel pipes, steel plates, channel steel, I-beams, etc., and through integrated design, it is easy to source materials, has a reasonable design, high structural strength, and good stability. It can be flexibly allocated and arranged according to actual use needs, is easy to transport, can be reused after being manufactured, has a wide range of applications, and is easy to install and dismantle.

[0024] To further understand the content of this utility model, a detailed description of the utility model is provided in conjunction with the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the utility model.

[0025] Example 1

[0026] Please see Figure 1-4 This embodiment provides a transport support device for precast cap beams with large cantilever arms, which includes a device body 100. The device body 100 includes a base 210 located on the floor of the transport vehicle. The base 210 is provided with a support component 220 corresponding to the fulcrum position of the precast cap beam. The support component 220 is used to provide support for the fulcrum position of the precast cap beam. The top of the support component 220 matches the slope of the bottom surface of the cap beam.

[0027] The main body of the device 100 is spot welded to the floor of the transport vehicle.

[0028] The present invention discloses a transport support device for precast cap beams with large cantilever arms. The support component 220 provides support to the fulcrum of the precast cap beam, which can effectively distribute the weight of the cap beam, avoid the center of gravity shift caused by weight concentration, reduce the possibility of the cap beam overturning due to shaking or bumping during transportation, eliminate a huge safety hazard, and ensure the safety of personnel and equipment during transportation.

[0029] Understandably, by matching the slope of the top of the support component 220 with the bottom surface of the cap beam, the support component 220 and the bottom surface of the cap beam have a larger contact area, which not only improves the connection stability between the support component 220 and the bottom surface of the cap beam, but also does not cause any appearance damage to the precast cap beam.

[0030] In this embodiment, the support component 220 includes two sets of base plates 310 disposed on the top wall of the base 210. Each base plate 310 is provided with a support tube 320 along the vertical direction. Each support tube 320 has a top plate 330 formed on its top wall that matches the slope of the bottom surface of the cap beam.

[0031] By setting support pipes 320 vertically along the bottom plate 310, stable vertical support can be provided for the precast cap beam. The top plate 330 formed at the top wall of the support pipe 320 matches the slope of the bottom surface of the cap beam, so that the support components can fit in close to the bottom surface of the cap beam. This not only provides uniform support force and avoids damage to the cap beam due to uneven local stress, but also better adapts to the height difference between the top of the pier and the end of the cantilever precast cap beam, further improving the stability and reliability of the support.

[0032] In this embodiment, a filling cavity 321 is formed inside the support tube 320, and a circular hole 331 communicating with the filling cavity 321 is provided at the top plate 330. The filling cavity 321 is filled with fine sand.

[0033] By filling the pipe with sand, the overall stability of the support pipe 320 is enhanced, enabling it to more effectively bear the weight of the cap beam and reducing the possibility of deformation or damage to the support pipe 320.

[0034] In this embodiment, a rubber pad 340 is provided at the top plate 330.

[0035] The rubber pad 340 protects the surface of the cap beam, preventing damage to its appearance. Furthermore, the roughness of the rubber pad increases friction between the top plate and the bottom of the cap beam, improving its stability during transport.

[0036] In this embodiment, multiple stiffening plates 410 are provided between the support tube 320 and the bottom plate 310, and between the top plate 330 and the support tube 320.

[0037] By setting stiffening plate 410, the overall rigidity of support tube 320 can be increased, enabling it to support precast cap beams more reliably.

[0038] In this embodiment, multiple lifting lugs 420 are provided on the outer wall of the support tube 320.

[0039] The above structure provides a reliable connection point for hoisting equipment (such as cranes), facilitating the hoisting and disassembly of this device.

[0040] In this embodiment, a connector 350 is provided between the two sets of base plates 310 and the base 210.

[0041] By connecting the two sets of base plates 310 to the base 210 through the connector 350, the overall structural strength of the device can be enhanced.

[0042] The base plate 310 and the top plate 330 are both made of steel plates, the support pipe 320 is made of steel pipe, and the base 210 is made of two I-beams welded horizontally.

[0043] This device is composed of steel pipes, steel plates, channel steel, I-beams, etc., and through integrated design, it is easy to source materials, has a reasonable design, high structural strength, and good stability. It can be flexibly allocated and arranged according to actual use needs, is easy to transport, can be reused after being manufactured, has a wide range of applications, and is easy to install and dismantle.
