Description

Technical Field

[0001] This utility model relates to the field of bridge crash barrier maintenance technology, and more specifically, to a protective device suitable for the construction of bridge crash barriers. Background Technology

[0002] Currently, during the reconstruction or repair of crash barriers on old bridges in cities, the removal or removal of damaged sections poses a safety hazard as concrete fragments can easily fall onto the road below, causing injury to people and vehicles. Furthermore, during finishing work after the crash barrier repairs are completed, paint or coatings can spill onto vehicles traveling below, causing damage, especially in windy weather. To ensure the safety of passing vehicles and pedestrians, construction companies typically apply for road occupancy permits from the municipal and district traffic management departments in advance. However, due to the large number of pedestrians and vehicles in urban areas, even without road occupancy, traffic pressure is very high. Therefore, obtaining road occupancy permits for bridges is difficult, and even when approved, it consumes a significant amount of time and effort. To address this, we have proposed a protective device suitable for bridge crash barrier construction. Utility Model Content

[0024] For details, please refer to Figure 3 The bottom ends of the two elbow steel pipes 2 are fixedly connected to the fixing bases 12, and the two fixing bases 12 are provided with fixing holes 13.

[0025] In this embodiment, the first steel pipe 1 can be fixed to the ground by the cooperation of the fixing seat 12, the fixing hole 13 and the screw.

[0026] For details, please refer to Figure 3 The end of the sheet metal receiving plate 7 is fitted with a leak-proof carpet cloth 15.

[0027] In this embodiment, the leak-proof carpet 15 is used to increase the sealing between the sheet metal receiving plate 7 and the outside of the crash barrier, ensuring that the sheet metal receiving plate 7 can receive concrete fragments, paint or coatings generated during the repair of the crash barrier.

[0028] For details, please refer to Figure 3 A reinforcing steel pipe 14 is fixedly connected between the elbow steel pipe 2 and the third straight steel pipe 4.

[0029] In this embodiment, the connection strength between the elbow steel pipe 2 and the third straight steel pipe 4 is increased by using the reinforcing steel pipe 14.

[0030] For details, please refer to Figure 3 The two ends of the green plant cloth 6 are connected to the end faces of the elbow steel pipe 2 and the third straight steel pipe 4, respectively.

[0031] In this embodiment, the green cloth 6 is designed to completely block the space between the two third straight steel pipes 4.

[0032] For details, please refer to Figures 1 to 3 The first straight steel pipe 1, the elbow steel pipe 2, the second straight steel pipe 3, the third straight steel pipe 4, the fourth straight steel pipe 5, and the reinforced steel pipe 14 are all galvanized steel pipes.

[0033] In this embodiment, to prevent rust from forming on the frame welded together by the first straight steel pipe 1, the elbow steel pipe 2, the second straight steel pipe 3, the third straight steel pipe 4, the fourth straight steel pipe 5, and the reinforcing steel pipe 14, the sheet metal receiving plate 7, the support base 8, the screw rod 9, and the rotating rod 10 are also galvanized.

[0034] Working principle: In use, two workers first move the device to the crash barrier, placing the sheet metal receiving plate 7 on the outside of the crash barrier and ensuring that the leak-proof carpet 15 at the end of the sheet metal receiving plate 7 contacts the outer surface of the crash barrier. Then, the workers hold the rotating rod 10 to rotate the screw 9, which moves the extrusion plate 11 through the threaded engagement between the screw 9 and the support seat 8, bringing the end face of the extrusion plate 11 into contact with the inner surface of the crash barrier. This assembles the device onto the crash barrier to be repaired. During the demolition or removal of damaged parts of the crash barrier, the removed concrete fragments fall onto the sheet metal receiving plate 7 for collection. Finally, when painting the crash barrier, the paint or coating is blocked by the sheet metal receiving plate 7 and the green cloth 6, preventing it from falling off.

[0035] 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.
