Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, and particularly relates to a pier top fence. Background Art

[0002] A pier is a structure that supports the bridge span structure and transmits the dead load and vehicle live load to the foundation. The abutments are located on both sides of the bridge. The bearing pad stone on the pier is called the bearing pad stone of the support. The bearing pad stone is the connecting part between the abutment, the top of the pier and the support. Whether the position of the bearing pad stone is accurate directly affects whether the support can be closely attached to the steel plate at the bottom of the precast beam. If the support is suspended, it will directly affect the service life of the support and even cause quality accidents. The construction process of the bearing pad stone requires workers to carry out corresponding operations on the pier top. To ensure construction safety, a fence will be set on the pier top; the traditional hanging fence generally buries threaded columns during the pouring of the pier for the later installation of triangular brackets, and then lays a backing plate and installs the fence on the triangular brackets. However, this installation structure not only has a long disassembly and installation time, but also has a large construction difficulty, greatly reducing the construction efficiency. Summary of the Utility Model

[0003] To overcome the deficiencies of the background art, the utility model provides a pier top fence, which solves the problems that the fence set on the pier top at present not only has a long disassembly and installation time but also has a large construction difficulty.

[0004] The technical scheme adopted by the utility model is as follows:

[0005] A pier top fence, comprising:

[0006] A fence, with an opening on one side of the fence;

[0007] A hoisting part, arranged on the top surface of the fence;

[0008] An installation frame, arranged on the bottom surface of the fence for sleeving on the pier;

[0009] A safety passage, used for connecting the fence, with both ends respectively arranged at the opening of the fence;

[0010] Limit plates, respectively arranged at the bottoms of both ends of the installation passage, and the limit plates are used for contacting with the pier wall;

[0011] A first protective fence, arranged on both sides of the safety passage.

[0012] The bottom surface of the safety passage is evenly distributed with anti-slip lines.

[0013] The inner wall of the installation frame is provided with a protective layer.

[0014] Reinforcing bars are arranged inside the fence.

[0015] The hoisting part is arranged on both sides of the reinforcing bars.

[0016] On both sides of the safety passage, there are first connecting parts, and on the fence, there are second connecting parts for cooperating with the first connecting parts. The first connecting parts and the second connecting parts are connected by bolts.

[0017] The fence includes a second protective fence and protective nets arranged on both sides of the second protective fence.

[0018] The beneficial effects of the present utility model are as follows:

[0019] When the fence is hoisted above the pier and the installation frame is sleeved on the pier top, the two ends of the opening of the fence are respectively connected to the safety passage, the fence structure is stable, the safety passage facilitates the movement of the staff between the left and right piers, and at the same time, the limiting plate prevents the fence from sliding left and right, ensuring the stability of the fence on the pier; this fence structure can effectively improve the construction efficiency.

[0026] The following further describes the present utility model in conjunction with the drawings and embodiments:

[0027] In the embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , as shown in 5, a pier top fence includes:

[0028] Fence 1, with an opening on one side of the fence 1;

[0029] Hoisting part 2, arranged on the top surface of the fence 1;

[0030] Installation frame 3, arranged on the bottom surface of the fence 1 for sleeving on the pier;

[0031] A safety passage 4, which is used to connect to the fence 1, and its two ends are respectively arranged at the openings of the fence 1;

[0032] Limit plates 13 are respectively arranged at the bottoms of the two ends of the installation passage 4, and the limit plates 13 are used to contact the pier wall;

[0033] The first protective fence 5 is arranged on both sides of the safety passage 4.

[0034] The fence 1 is hoisted above the pier, so that the installation frame 3 is sleeved on the pier top. When the two ends of the opening of the fence 1 are respectively connected to the safety passage 4, the structure of the fence 1 is stable. The safety passage 4 facilitates the movement of the staff between the left and right piers.
