Description

Technical Field

[0001] This utility model relates to the field of bridge protection technology, and in particular to a drip plate structure for the protection of bridge side panels. Background Technology

[0002] The damage caused by rainwater to bridges is not immediately apparent, but rather a cumulative process "from the surface to the interior, from the local to the overall structure." Initially, it may only manifest as surface powdering of concrete and slight corrosion of guardrails, but if not addressed promptly, it will gradually develop into steel reinforcement corrosion, structural cracking, and component failure, ultimately affecting the bridge's load-bearing capacity and safety. Statistics show that approximately 30% of bridge defects in my country are directly related to rainwater erosion, and annual bridge repair costs due to rainwater erosion account for more than 40% of total maintenance costs. Therefore, in bridge design and operation, "waterproofing and protection" (such as applying a waterproof layer to the concrete surface, regularly reapplying anti-rust paint to metal components, and cleaning the drainage system) are crucial for ensuring the long-term safety of bridges.

[0003] If drip plates, small components, can be used to guide and divert water accumulation on bridges, intercept rainwater and natural rainwater from the bridge surface, and prevent water from flowing along the side of the edge plate or seeping into the interior, long-term seepage can prevent steel corrosion caused by the concrete edge plate, thereby preventing concrete cracking and spalling, ensuring the load-bearing capacity of the edge plate, preventing beam erosion, and extending the overall life of the bridge, then a drip plate structure for the protection of bridge edge plates is needed to meet practical requirements. Utility Model Content

[0004] The purpose of this invention is to provide a drip plate structure for the protection of bridge side panels, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drip edge structure for bridge side panel protection, comprising a bridge body, characterized in that: a bridge railing is installed on the bridge body, a bridge deck is laid on the bridge body, a main beam is installed at the bottom of the bridge body, a flange plate is provided on the main beam, a waterproof coating is applied to the flange plate, a drip edge plate is provided on the waterproof coating, and M10 expansion bolts are installed on the flange plate, the waterproof coating, and the drip edge plate.

[0006] Preferably, the waterproof coating is made of modified epoxy resin.

[0007] Preferably, the drip edge plate is provided with a sloping opening, the sloping opening being between 15 and 45 degrees.

[0008] Preferably, the drip edge plate is made of aluminum alloy, and the surface of the drip edge plate is provided with an anti-rust coating.

[0009] Preferably, the anti-rust coating is produced by galvanizing an aluminum alloy substrate by immersing it in a high-temperature zinc solution.

[0010] The beneficial effects of this utility model are:

[0011] This invention, through the application of waterproof coatings, drip edges, and sloping openings, can divert and guide rainwater, controlling water flow to protect the superstructure. Its core function is primarily to prevent backflow of water from corroding the flange plates, protecting the flange plates and the main beam structure. By intercepting rainwater and natural rainwater from the bridge deck, it prevents water from flowing along the flange plates or seeping into the interior, thus avoiding long-term seepage that could lead to steel reinforcement corrosion in the concrete flange plates. This prevents concrete cracking and spalling, ensuring the load-bearing capacity of the flange plates, reducing the frequency and cost of maintenance and replacement, and extending the lifespan of the bridge structure.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Example:

[0017] like Figure 1-2As shown, this embodiment provides a drip edge structure for bridge side panel protection, including a bridge body 1, a bridge railing 2 installed on the bridge body 1, a bridge deck paving 3 laid on the bridge body 1, a main beam 4 installed at the bottom of the bridge body 1, a flange plate 5 installed on the main beam 4, a waterproof coating 6 applied to the flange plate 5, and a drip edge plate 7 installed on the waterproof coating 6. M10 expansion bolts 8 are installed on the flange plate 5, the waterproof coating 6, and the drip edge plate 7. The surface of the flange plate 5 is cleaned, the waterproof coating 6 is applied to the flange plate 5, and the drip edge plate 7 is fixed to the flange plate 5 with the M10 expansion bolts 8. The waterproof coating 6 can seal the connection between the flange plate 5 and the drip edge plate 7, preventing rainwater penetration. Rainwater on the bridge body 1 can be guided and diverted through the drip edge plate 7, preventing backflow and corrosion of the flange plate 5 and penetration, protecting the structure of the flange plate 5 and the main beam 4, preventing the main beam 4 from being eroded, and extending the overall service life of the bridge body 1. This directs the water flow away from the lower structures such as supports, piers, and abutments on the bridge body 1, preventing the water flow from directly eroding the supports and causing accelerated aging and seal failure, thus ensuring their shock absorption and force transmission functions.

[0018] To improve the durability and stability of waterproof coating 6, the material of waterproof coating 6 is modified epoxy resin; epoxy resin material has good durability and stability, and can meet the needs of long-term exposure to the external environment.

[0019] To avoid drainage problems such as water accumulation and backflow, the drip edge plate 7 is equipped with a sloping opening 9, which has a range of 15 to 45 degrees. The sloping opening 9 can change the flow direction and speed of rainwater. Rainwater will slide quickly outward along the inclined surface of the sloping opening 9, instead of flowing slowly or stagnating on the horizontal surface. This changes the flow path of rainwater and solves the core drainage problems such as water accumulation and backflow.

[0020] To reduce the weight of the drip edge plate 7 and improve its strength and rust resistance, the drip edge plate 7 is made of aluminum alloy with a rust-proof coating. This coating is applied using a galvanizing process, where the aluminum alloy substrate is immersed in a high-temperature zinc solution. The lightweight yet high-strength aluminum alloy meets the requirements of the drip edge plate 7, and the rust-proof coating enhances its corrosion resistance, preventing rust and extending its service life.

[0021] Working principle: During use, clean the surface of the flange plate 5, apply the waterproof coating 6 to the flange plate 5, and then fix the drip edge plate 7 to the flange plate 5 using M10 expansion bolts 8. The waterproof coating 6 seals the connection between the flange plate 5 and the drip edge plate 7, preventing rainwater from seeping in. The bridge body 1 is a small component installed on the flange plate 5, shaped like a thin, outwardly projecting plate. As a key component of the waterproof and anti-corrosion system of the bridge body 1, it is specifically used for water flow control during bridge deck paving 3 to protect the superstructure. Its core function is primarily to prevent backflow of water that corrodes the flange plate 5, protecting the structure of the flange plate 5 and the main beam 4. By intercepting rainwater and natural rainwater on the bridge deck paving 3, water flow is prevented from flowing along the flange plate 5 or seeping into the interior. This prevents long-term seepage from causing steel corrosion in the concrete flange plate 5, thus preventing concrete cracking and spalling, and ensuring the load-bearing capacity of the flange plate 5. At the same time, it protects the connection between the flange plate 5 and the main beam 4, preventing the main beam 4 from being corroded and extending the overall life of the bridge body 1. Secondly, it guides the direction of water flow and avoids scouring of the substructure. It directs the water flow on the flange plate 5 away from the bearings, piers, abutments, and other substructures, preventing water from directly scouring the bearings, which would lead to accelerated aging and seal failure, thus ensuring their shock absorption and force transmission functions. It also prevents the backfill and gravel around the pier or abutment foundations from being washed away due to long-term scouring, maintaining foundation stability and preventing risks such as settlement and tilting of the bridge body 1. Furthermore, it reduces pollution on the bridge deck paving 3 and keeps the structure's appearance clean. The dust, debris, oil, and other pollutants carried by rainwater on the bridge deck paving 3 will be diverted away from the flange plate 5 by dripping water along the slab 7, reducing the formation of stains on the flange plate 5 surface. This maintains a clean appearance and prevents the slow erosion of the flange plate 5 concrete by pollutants. As a small component, this part has the advantage of effectively protecting the flange plate 5, main beam 4, and substructure by blocking seepage and diverting water, reducing the probability of erosion damage and demonstrating outstanding protective function; it can avoid structural damage caused by water erosion, reduce the frequency and cost of maintenance and replacement, and extend the life of the bridge body 1; it can reduce stains on the flange plate 5, keep the structure clean and beautiful, and improve the appearance quality; moreover, it is easy to design and install, plays a key role in the safe maintenance of the bridge body 1, and is extremely practical.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
