Description

Technical Field

[0001] The utility model relates to the technical field of bridge engineering, in particular to a safety steel box beam structure. Background Art

[0002] Steel box beam is a component commonly used in bridges and building structures. Its cross-sectional shape is similar to a rectangular box, so it is called a "box beam". It is usually made of steel, but other materials such as concrete can also be used. The existing steel box beam is not safe. If deformation occurs, it is difficult to detect. The existing steel box beam has no waterproof function and may cause water accumulation. The existing steel box beam is not convenient to hoist during installation. The existing assembled steel hybrid bridge structure (publication number: CN219045088U) has at least the following shortcomings in use:

[0003] 1. The existing steel box girder has deformation that is not easy to detect and may cause serious bridge accidents, which seriously affects its safety and reliability. It needs further improvement and strengthening to ensure structural safety, so a high-safety steel box girder is urgently needed.

[0004] 2. Existing steel box girders lack built-in waterproof design, which makes it easy for water to accumulate inside them when encountering rain, floods or overflows. This may not only cause internal corrosion of the beam body, reduce structural strength and affect the service life of the bridge, but the accumulated water may also provide an environment for bacteria to breed, affecting the sanitation of the bridge. Long-term accumulation of water may also cause structural fatigue, increase the risk of bridge cracks, and even cause structural instability. Therefore, a rainproof steel box girder is urgently needed.

[0005] 3. The main disadvantage of the existing steel box girder during installation is the difficulty in lifting. First, due to its heavy weight and complex shape, traditional lifting equipment may be difficult to accurately align with the reserved holes, increasing the challenge of installation accuracy, which may lead to extended construction time, increased labor costs and construction risks. Secondly, the irregular shape of the steel box girder may cause uneven force on the sling, aggravating the wear of the sling and crane equipment, and affecting the service life of the equipment, so a steel box girder that is easy to lift is urgently needed. Utility Model Content

[0006] The main purpose of the utility model is to provide a safe steel box girder structure, which can effectively solve the problems in the background technology.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A safety steel box girder structure comprises a top bridge, a guide trough is installed above the top bridge, a guide plate is installed below the guide trough, a side plate is installed on the right side of the top bridge, a strain gauge is installed inside the top bridge, a bottom column is installed on the left side of the side plate, a top column is fixedly installed above the bottom column, a buzzer is installed on the left side of the top column, a partition is connected below the top column, and plate holes are nested inside the partition.

[0009] Preferably, six base columns are distributed laterally.

[0010] Preferably, eight top columns are distributed laterally.

[0011] Preferably, the buzzer is internally connected to a strain gauge.

[0012] Preferably, the left side of the guide plate is designed to be arc-shaped.

[0013] Preferably, three plate holes are arranged transversely.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model adopts a structure combining a strain gauge and a buzzer. When the slight strain change on the top of the bridge structure is monitored, the strain gauge sensitively captures and converts it into an electrical signal. This design enables the buzzer to issue an immediate warning through real-time transmission, reminding us of the potential safety hazards of the bridge structure in the form of sound. This intelligent early warning system significantly improves the efficiency of bridge safety monitoring and prevents accidents caused by structural problems. The advantage is that it realizes early warning, avoids accidents, improves public safety, and saves time and cost of manual inspections. Through non-invasive and automated monitoring, bridge maintenance is more refined and timely.

[0016] 2. The utility model ingeniously uses the design of guide troughs and guide plates to solve the problem of water accumulation inside the steel box girder. The existence of the guide trough is like a natural drainage channel, guiding rainwater to flow through a preset path, ensuring that rainwater is quickly discharged and preventing accumulation inside the beam body. The guide plate serves as an auxiliary facility to guide rainwater to flow into the guide trough, increasing the guidance and stability of drainage. This structural optimization not only improves drainage efficiency and reduces the risk of corrosion of the steel box girder structure by accumulated water, but also improves the durability and service life of the bridge. Its advantages are that it improves the flood control performance of the system, reduces maintenance requirements, and ensures the safe operation of the bridge under extreme weather conditions.

[0017] 3. The unique design of the utility model is to construct a stable and flexible support system by configuring six bottom columns and eight top columns. Such structural design provides a variety of lifting options, so that the steel box girder can adapt to different construction environments and lifting equipment during the installation process, and enhance the stability and reliability of the lifting. The six bottom columns ensure the firmness of the foundation, while the eight top columns provide more fulcrums, so that the balanced force distribution can be maintained under the lifting requirements of different periods and angles. This not only significantly reduces the difficulty of lifting and shortens the construction period, but also reduces the risk of structural damage caused by improper operation. Overall, this design optimizes construction efficiency, improves structural safety, and is a key innovation in engineering implementation. BRIEF DESCRIPTION OF THE DRAWINGS
