[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the solution of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.

[0027] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.

[0029] The following is combined with Figures 1 to 3 The specific embodiments of this utility model will be described in detail below.

[0030] This embodiment provides a combined protective device for pier tops, including a U-shaped retaining rod 1, a connecting base 2, a pipe seat 3, a railing 4, and a protective net 5.

[0031] Among them, there are multiple U-shaped retaining bars 1, which are distributed at intervals along the circumference of the pier top. Each U-shaped retaining bar 1 is pre-embedded and fixed on the pier top with its opening facing downward.

[0032] It should be noted that work on the pier top is considered high-altitude work, and safety protection measures should be taken in accordance with relevant regulations during construction. Before pouring concrete for the pier cap, U-shaped retaining rods 1 will be pre-embedded during construction to facilitate the installation of hanging guards and the securing of safety belts for workers later. This protective device utilizes the existing U-shaped retaining rods 1 on the pier top as part of the structure. When pre-embedding the U-shaped retaining rods 1, in addition to considering their use as safety belt fasteners, their compatibility with the connecting base 2 of this protective device should also be considered to ensure structural strength.

[0033] Specifically, in this embodiment, the U-shaped reinforcing bar 1 is made of HPB300 steel bar with a diameter of 16mm, a embedment depth of 200mm, and an exposed portion of 50mm. The exposed portion is treated with hot-dip galvanizing for corrosion protection. The U-shaped reinforcing bar 1 should be welded to the longitudinal reinforcing bars of the pier top cap. The material is available on site and can be used directly.

[0034] Specifically, in this embodiment, the number of U-shaped retaining rods 1 is no less than 8. The specific number can be adjusted appropriately according to the pier top size. For example, when the pier top size is 8m in the transverse direction and 3.4m in the longitudinal direction, the number of U-shaped retaining rods 1 is designed to be 8; when the pier top size is 15.5m in the transverse direction and 3.4m in the longitudinal direction, the number of U-shaped retaining rods 1 is designed to be 28.

[0035] Among them, the connecting base 2 is a spliced ​​ring structure and is inserted inside all the U-shaped clamps 1.

[0036] Specifically, the connecting base 2 in this embodiment includes horizontal ribs 21, vertical ribs 22, and diagonal ribs 23. The horizontal ribs 21 and vertical ribs 22 are fixedly connected by the diagonal ribs 23. The horizontal ribs 21 and / or vertical ribs 22 are spliced ​​from several standard sections. The diagonal ribs 23 connect the horizontal ribs 21 and vertical ribs into a single structure to ensure structural stability.

[0037] It should be noted that the length of the transverse reinforcement 21 is fixed, while the length of the longitudinal reinforcement 22 is adjusted and combined according to the length of the pier cap.

[0038] It is easy to understand that the horizontal reinforcement 21 is arranged along the transverse direction of the bridge, the longitudinal reinforcement 22 is arranged along the longitudinal direction of the bridge, and there are two horizontal reinforcements 21 and two longitudinal reinforcements 22. There are four diagonal reinforcements 23 to complete the connection between the horizontal reinforcement 21 and the vertical reinforcement.

[0039] More specifically, in this embodiment, both the transverse ribs 21 and the longitudinal ribs 22 are channel steels with their openings facing downwards, and the channel steels of adjacent standard sections are fixedly connected by bolts.

[0040] In detail, in this embodiment, the standard section length is 2m, and the standard sections are connected by 8.8 grade high-strength bolts. In actual operation, a connecting plate can be used, which is simultaneously overlapped onto two standard sections and then fixed with bolts. The diagonal rib 23 can also be made of channel steel, which is directly overlapped onto the transverse rib 21 and the longitudinal rib 22 and then connected with bolts. All parts can be disassembled and connected, which is more convenient for disassembly.

[0041] It should be noted that, in order to ensure the smooth installation of the base 2 later, the opening of the U-shaped clamp 1 should be larger than the width of the channel steel. For example, the channel steel used in this embodiment is 10# channel steel, the width of 10# channel steel is 10cm, and the opening size of the U-shaped clamp 1 is 12cm.

[0042] It should be noted that, in actual operation, the length of the standard section extending beyond the edge of the pier top should not exceed 20cm.

[0043] Among them, there are multiple tube seats 3, which are distributed at intervals along the connecting base 2, and each tube seat 3 is fixed on the connecting base 2.

[0044] Specifically, in this embodiment, the tube seat 3 is cylindrical.

[0045] More specifically, the diameter of the columnar tube seat 3 is 41 mm and the height is 60 mm.

[0046] The railing 4 has multiple rails, each corresponding to a pipe seat 3, and the bottom end of the railing 4 is fixed to the corresponding pipe seat 3.

[0047] Specifically, in this embodiment, the railing 4 is a steel pipe, and the bottom end of the steel pipe is sleeved and fixed on the corresponding pipe seat 3.

[0048] More specifically, the steel pipe has an outer diameter of 48mm, a wall thickness of 3mm, and a height of 1.2m. After the steel pipe is fitted onto the pipe seat 3, it is fixed by a horizontally inserted pin, which facilitates disassembly.

[0049] Among them, the protective net 5 is fixed to all the railings 4 to form a closed enclosure.

[0050] Specifically, the protective net 5 in this embodiment includes multiple mesh panels, each of which is fixed between two adjacent railings 4. This makes installation more convenient, and the multiple mesh panels bear the load independently, resulting in stronger structural stability.

[0051] More specifically, the mesh is fixed to the railing 4 using cross-shaped tube clamps.

[0052] More specifically, the mesh panel uses a finished product with a width of 2m and a height of 1.2m.

[0053] It should be noted that, to ensure service life and effectiveness, the protective netting is made of high-quality steel, featuring insulation, flame retardancy, and corrosion resistance.

[0054] The installation process of the combined protective device on the pier top in this embodiment is as follows:

[0055] S1. U-shaped reinforcing bar pre-embedded on the top of the pier;

[0056] S2. Pre-assemble the connecting base 2 and the tube seat 3, and then assemble the connecting base 2 with the tube seat 3 into the U-shaped clamp 1;

[0057] S3. Install railing 4;

[0058] S4. Install protective netting.

[0059] The above are merely specific embodiments of this utility model, enabling those skilled in the art to understand or implement this utility model. Although detailed descriptions have been provided with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments, and they should all be covered by the protection scope of the claims.
