[0035] Steel box girders are important load-bearing structures in road and bridge construction. They consist of multiple constituent units and are extremely heavy. Before being put into use, multiple steel box girders need to be stored together. Due to their weight, steel box girders are susceptible to external environmental influences during long-term storage. For example, ordinary sites can cause uneven stress on the steel box girders, leading to deformation, or high humidity can cause them to rust.
[0036] This utility model proposes a steel box girder support structure 100 to solve the above problems.
[0037] Please see Figures 1 to 4 In one embodiment of this utility model, a support structure is mainly provided for storing steel box girders. Steel box girders are important load-bearing structures in road and bridge construction, containing multiple constituent units and possessing immense weight. Before being put into use, multiple steel box girders need to be stored uniformly. During storage, the steel box girders are susceptible to external environmental influences. For example, due to the large self-weight of the steel box girder, unevenness in the support structure can easily cause internal structural deformation, thus affecting its overall rigidity. Alternatively, poor drainage in the support structure can lead to premature corrosion of the outer surface of the steel box girder after prolonged contact with rainwater. To minimize the impact of the external environment on the steel box girder structure, this embodiment proposes a steel box girder support structure 100, which includes multiple support members 2 and measuring members 4. Specifically, the support members 2 include a steel frame structure 21 and pad blocks 22, such as...Figure 1 As shown, the multiple steel frame structures 21 are specifically configured as four, arranged in a rectangular four-point configuration, thus forming four evenly spaced support points on the foundation structure 1. The upper support surface of the foundation structure 1 is relatively flat and, after treatment, possesses a certain supporting strength, effectively preventing the steel frame structures 21 from sinking due to load. In use, the corresponding pad blocks 22 are vertically mounted on the upward-facing end of the steel frame components. During actual use, the vertical support height of the pad blocks 22 on the steel frame structure 21 can be adjusted, ensuring that the support surfaces of the multiple pad blocks 22 are on the same horizontal plane, allowing the steel box girder to bear force as evenly as possible. The measuring component 4 includes multiple measuring ends 41, which are respectively installed on multiple pad blocks 22 and are interconnected. Through the interconnected multiple measuring ends 41, the height difference between the multiple pad blocks 22 can be reflected, thereby providing an effective reference for the vertical adjustment of the pad blocks 22.
[0038] Specifically, the pad block 22 is slidably mounted vertically on the upward end of the steel frame structure 21. A shim structure 3 is provided between the pad block 22 and the end of the steel frame structure 21. By adding or removing the corresponding shim structure 3, the height of the support surface of the pad block 22 can be adjusted. It is conceivable that the shim structure 3 can be configured as a sheet structure of various thicknesses, allowing for selective combination based on the vertical differences of multiple pad blocks 22, thereby forming shim combinations with different support thicknesses to suit different adjustment scenarios.
[0039] Specifically, a mounting hole 211 is provided on the upward end face of the steel frame structure 21. The pad block 22 includes a block portion 221 and a guide rod portion 222. During installation, the guide rod portion 222 is slidably installed at the mounting hole 211, and the block portion 221 is located at the upward end of the steel frame structure 21. When adjusting the support height of the block portion 221, a corresponding shim structure 3 can be added between the upper end of the steel frame structure 21 and the block portion 221. It should also be noted that the above adjustment process is generally performed before placing the steel box girder on the block portion 221. If, during the support of the steel box girder, part of the block portion 221 sinks, a jacking structure, such as a jack, can be placed inside the steel frame structure 21 with its end aligned with the downward end of the guide rod portion 222. The block portion 221 can be lifted by the jack, and then the shim structure 3 can be added between the end of the steel frame structure 21 and the block portion 221.
[0040] In order to achieve the above-mentioned adjustment of the pad structure 3 during the support process, in this embodiment, the pad body is provided with a clearance slot 31 corresponding to the guide rod part 222. When the corresponding pad structure 3 is actually added between the steel frame structure 21 and the block part 221, the clearance slot 31 is aligned with the guide rod part 222, so that the pad structure 3 can be placed in the middle position between the steel frame structure 21 and the block part 221, making the operation process more convenient.
[0041] The measuring end 41 includes a spherical part 411 and a measuring tube 412. The spherical part 411 is installed on the side wall of the block part 221. The spherical part 411 is a hollow sphere with a hole structure at its upward position for installing the measuring tube 412. The measuring tube 412 has a vertical cavity and an opening 4121 at its upward end. The air pressure inside and outside the measuring tube 412 can be balanced through the opening 4121.
[0042] Specifically, this scheme uses water as the measurement medium for levelness. For example, Figure 1 As shown, the multiple spherical sections 411 are interconnected via connecting pipes 42. In actual use, a certain amount of water is injected into the connecting pipes 42 and the multiple spherical sections 411 through the water inlet pipe 421. The amount of water injected needs to form a water column of a certain height in the multiple measuring pipes 412. In actual use, the height of the water column in the multiple measuring pipes 412 reflects the height of the corresponding block section 221. It can be imagined that if the multiple block sections 221 are at the same vertical height, then the height of the water column in the multiple measuring pipes 412 should be at the same height. If the height of the water column in the corresponding measuring pipe 412 is lower, it reflects that the height of the block section 221 at the corresponding position is higher than that of other block sections 221, and vice versa. In this way, the height of the water column in the measuring tube 412 can be reflected as the vertical height difference of the corresponding block part 221, thereby facilitating the adjustment of the support height of the corresponding block part 221 by relevant technicians.
[0043] In addition, to facilitate the installation and disassembly of the entire structure, in this embodiment, the connecting pipe 42 and the spherical part 411 are connected by threads.
[0044] To facilitate visual identification of the water column height inside the measuring tube 412, in this embodiment, the measuring tube 412 is at least partially transparent, and scale lines are provided on its outer wall. These features allow for better identification of the actual water column height within each measuring tube 412.
[0045] The block portion 221 is made of wood, which provides a certain degree of support strength and, to some extent, avoids hard contact with the steel box girder, thus protecting the surface structure of the steel box girder as much as possible. Furthermore, the support positions of the multiple block portions 221 are also somewhat restricted. Specifically, each of the multiple steel frame structures 21 is positioned at the intersection of the web and diaphragm of the steel box girder. This allows for direct support at the joints, providing a more stable support structure.
[0046] Specifically, the foundation structure 1 includes a crushed stone layer 11 and a concrete layer 12. During actual construction, the ground is first leveled, then a crushed stone layer 11 of appropriate thickness is laid on the leveled ground, followed by a concrete layer 12 on top of the crushed stone layer 11, thereby maximizing the foundation's support. Multiple upward-protruding mounting portions 121 are also provided on the concrete layer 12. The steel frame structure 21 is correspondingly installed on these mounting portions 121. During actual installation, the rigid connection structure can be prefabricated and directly installed on the mounting portions 121, which is not only convenient but also effectively reduces costs.
[0047] To facilitate drainage, a drainage trough 122 is provided on one side of the concrete layer 12 corresponding to the plurality of steel frame structures 21, and the upper end surface of the concrete layer 12 is inclined, with its inclination direction tilting downward from the middle position toward the drainage trough 122. Rainwater can be discharged onto the drainage trough 122 from the inclined end surface, thereby ensuring the dryness of the area below the steel box girder.
[0048] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
