Description

Technical Field

[0001] This utility model relates to the technical field of drainage facilities for bridge engineering, specifically a drip edge for bridge pier cap beams. Background Technology

[0002] Bridge drainage is a crucial aspect of bridge construction. There are various methods of bridge drainage. One method is to use the bridge drip edge to connect with the bridge at different angles, creating an inclined design or a guide channel. This guides rainwater to designated drainage outlets or downpipes, protecting the bridge's substructure (such as piers and supports) from erosion. Bridge drip edges play a vital role in the bridge drainage process.

[0003] Current bridge construction, because bridge piers and cap beams are exposed to the natural environment for a long time after construction, different weather conditions will have different effects on the bridges. Long-term erosion by rainwater will cause water to seep in and corrode the bridge structure. In some cold regions, water seeps into the bridge cracks and freezes and expands, causing the bridge structure to fall off, thus affecting the service life of the bridge. Traditional bridge pier cap beam drip edges have many problems, such as inconvenient installation, poor waterproof performance, low durability, and inability to effectively block rainwater seepage. This leads to frequent weathering of the bridge surface and rusting of the steel structure, which also increases the maintenance cost and safety hazards of the bridge. In addition, the current installation position and angle of drip edges are relatively simple, which can lead to inconvenience in installation or difficulty in achieving waterproof effect when facing different bridge types. Moreover, once the drip edges are installed and fixed, it is also quite troublesome to replace them after damage.

[0004] In summary, to address the problems of poor waterproofing performance, inconvenient installation, and cumbersome disassembly and replacement of drip edges in existing technologies, a drip edge for bridge pier cap beams is proposed. Utility Model Content

[0005] In response to the different situations described above, this utility model provides a drip edge for a bridge pier cap beam.

[0006] This utility model relates to a drip edge for a bridge pier cap beam. It is characterized by comprising a base, with a connecting shaft integrally formed below the base. The connecting shaft is rotatably connected to a drip edge base plate. An arc-shaped groove is integrally formed at one end of the drip edge base plate near the base. The arc-shaped groove is rotatably connected to the connecting shaft. Multiple sets of threaded holes for the connecting shaft and the drip edge base plate are respectively formed in the radial direction at the connection point between the arc-shaped groove and the connecting shaft. Bolts are threadedly connected to the threaded holes of the drip edge base plate and the threaded holes of the connecting shaft. A drip edge head is slidably mounted on the upper surface of the drip edge base plate away from the threaded holes of the drip edge base plate. A spring block is provided below the drip edge head.

[0007] Preferably, the upper surface of the drip edge base plate is provided with a spring block slide, and spring block slots are provided on both sides of the spring block slide. A dovetail groove is provided on the upper surface of the drip edge base plate near the threaded hole.

[0008] Preferably, a spring block slider is provided below the drip edge, and the drip edge is slidably connected to the spring block slide of the drip edge base plate through the spring block slider.

[0009] Preferably, the spring block includes a spring block, a spring, and a spring block shaft. Spring block shafts are provided on both sides of the spring block, and spring blocks are sleeved on the outer walls of the spring block shafts. Springs are installed between the spring blocks and the spring block, and the spring blocks are engaged with the spring block slots provided on both sides of the spring block slide.

[0010] The beneficial effects of the above technical solution are as follows:

[0011] (1) This solution uses threaded holes of different directions on the connecting shaft of the integrated design on the base, and waterproof rubber plugs are installed in the unused threaded holes of the connecting shaft. This allows the drip edge base plate to have multiple angles to choose from when connecting with the connecting shaft, and also provides waterproof treatment. Furthermore, the drip edge base plate is designed with a similar arc shape at the connection with the connecting shaft, and there is a threaded fit between the drip edge base plate and the connecting shaft of the base in the arc groove. After the fit is completed, a waterproof layer is also applied at the connection, which achieves a tight fit at multiple angles and also stabilizes the waterproof performance.

[0012] (2) In this scheme, the drip edge bottom plate is treated by central shelling to reduce its weight and have stable performance.

[0013] (3) In this scheme, a slider and a spring block are provided on the side away from the connecting shaft below the drip eaves. A slide and a spring block slot are provided on the drip eaves base plate. When the installer assembles the drip eaves and drip eaves base plate, he only needs to push and slide lightly. The spring block will pop out from the slot to fix it. When replacing, he only needs to press the spring block along the spring shaft and then pull out the drip eaves to replace it.

[0027] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 11 As will be clearly shown in the detailed description of the embodiments, the structural contents mentioned in the following embodiments are all based on the accompanying drawings.

[0028] Example 1: This example provides a drip edge for a bridge pier cap beam, as shown in the attached diagram. Figure 1 , Figure 8 , Figure 9As shown, the device includes a base 1, with a connecting shaft 14 integrally formed below the base 1. The connecting shaft 14 is rotatably connected to a drip edge base plate 2. The drip edge base plate 2 has an integrally formed arc-shaped groove 21 at one end near the base 1. The arc-shaped groove 21 is rotatably connected to the connecting shaft 14. At the connection point between the arc-shaped groove 21 and the connecting shaft 14, multiple sets of threaded holes 13 for the connecting shaft and threaded holes 8 for the drip edge base plate are respectively opened in the radial direction. Bolts 12 are threadedly connected to the threaded holes 13 and 8. A drip edge 3 is slidably installed on the upper surface of the drip edge base plate 2 away from the threaded holes 8. A spring block 4 is provided below the drip edge 3.

[0029] Specifically, the system includes a base 1 and a drip edge base plate 2. The two are threaded together via a connecting shaft 14 below the base 1 and an arc-shaped groove 21 on the drip edge base plate. The connecting shaft 14 below the base has multiple threaded holes 13 arranged in a ring around its shaft surface. The arc-shaped groove on the drip edge base plate allows for threaded connections in different directions, creating different angles with the base to accommodate bridges of varying slopes and shapes. After the threaded connection is complete, the remaining threaded holes are sealed with rubber plugs for waterproofing. The groove 21 and the base 1 are sealed and waterproofed using polyurethane waterproof coating. The area above the base that contacts the bridge is treated with acrylic elastic waterproof coating, which provides excellent UV resistance and allows for color adjustment to match the bridge's appearance. The threaded connection reinforces the connection between the connecting shaft 14 on the base 1 and the arc-shaped groove 21 on the drip edge base plate 2, while also providing a waterproof seal. This effectively waterproofs the drip edge while ensuring its stability. Furthermore, due to the separate design of the drip edge base plate and the base, only the base or the drip edge base plate needs to be replaced if the drip edge is damaged.

[0030] Example 2, based on Example 1, such as Figure 3 As shown, a spring block slide 10 is provided on the upper end face of the drip edge base plate 2. Spring block slots 5 are provided on both sides of the spring block slide 10. A swallow-shaped groove 6 is provided on the upper end face of the drip edge base plate 2 near the threaded hole 8.

[0031] Specifically, the upper surface of the drip edge base plate 2 is provided with a spring block slide 10 to provide a sliding connection with the drip edge head 3. Both sides of the spring block slide 10 are provided with spring block slots 5 to engage with the spring blocks 4 provided on the spring block slider 9. The drip edge base plate 2 has a dovetail groove structure near the connecting shaft 14. This design allows the water flow to be buffered as it flows from the base into the drip edge, reducing the pressure on the drip edge base plate and maximizing its service life.

[0032] Example 3, based on Example 2, such as Figure 4 , Figure 5 , Figure 6 As shown, a spring block slider 9 is provided below the drip edge 3, and the drip edge 3 is slidably connected to the spring block slide 10 of the drip edge base plate 2 through the spring block slider 9.

[0033] Specifically, a small sliding groove 11 and a spring block slider 9 are provided below the drip edge 3, and a small slider 7 and a spring block slider 9 are provided above the drip edge base plate. During installation, the worker only needs to align the small sliding groove 11 with the small slider 7 and the spring block slider 9 with the spring block slide 10, slide them inwards, and press the spring block 41 on the spring block 4 so that the slide can pass through the spring block slot normally. When the slide reaches the matching position, release the spring block 41 on the spring block 4. Due to the force of the spring 42, the spring block 41 will pop out and cooperate with the spring block slot to fix the drip edge 3 and the drip edge base plate 2. If the drip edge is damaged and needs to be replaced, press the spring block 41 and slide the drip edge 3 outwards to remove it for replacement. The separate design of the drip edge 3 and the drip edge base plate 2 allows the drip edge 3 to be replaced. Replacement is performed when damaged, avoiding the need to replace the entire drip edge once damaged, thus reducing usage costs. Furthermore, the drip edge head 3 and drip edge base plate 2 are connected by sliding and fixed by spring blocks, which can improve the installation efficiency of installers more quickly. When damage is required for replacement, disassembly is also convenient, improving the work efficiency of workers and providing convenience.

[0034] Example 4, based on Example 3, such as Figure 6 and Figure 7 As shown, the spring block 4 includes a spring block 41, a spring 42 and a spring block shaft 43. The spring block 4 has a spring block shaft 43 on both sides. The outer wall of the spring block shaft 43 is fitted with a spring block 41. The spring block 41 and the spring block 4 are both installed with spring 42. The spring block 41 cooperates with the spring block slots 5 provided on both sides of the spring block slide 10.

[0035] Specifically, the spring block 41, spring 42, and spring block shaft 43 form a spring block unit. When the spring block 41 is pressed, it moves closer to the spring block 4 along the spring shaft, passing through the spring block slot 5, thus forming normal sliding between the spring block slider 9 and the spring block slide 10. When the spring block 41 and the spring block slot 5 are in the engaged position, releasing the spring block 41 will cause it to pop out due to the force of the spring 42, locking the spring block slot 5, thereby forming a complete spring block unit.

[0036] Working principle: In practical use, the drip edge base plate 2 is placed flat on the ground. Next, the base 1 is erected, and the angle is adjusted according to the different bridge surfaces. Then, the connecting shaft 14 is pressed against the arc-shaped groove 21 of the drip edge base plate 2, aligning with the threaded hole 8 on the drip edge base plate and the threaded hole 13 on the connecting shaft. Bolts 12 are used for threaded connection. Unused threaded holes are sealed with rubber plugs. Then, the small sliding groove 11 below the drip edge and the small sliding track 7 above the drip edge base plate are connected. Align the spring block slider 9 below the drip edge with the spring block slide 10 on the drip edge base plate, and then slide them together. When passing through the spring block slot 5, press down the spring block 41 to allow it to pass through the spring block slot 5 normally. When sliding to the mating position, the spring block 41 will pop out and lock the spring block slot 5 due to the force of the spring 42. When it is necessary to remove the drip edge 3, simply press down the spring block 41 when passing through the spring block slot 5 to allow it to slide normally through the spring block slot 5, and the drip edge 3 can be removed.

[0037] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
