Technical Field

[0001] The utility model relates to the technical field of anti-collision piers, in particular to anti-collision piers for roads and bridges. Background Art

[0002] Road and bridge crash barriers are important safety facilities used to protect transportation facilities such as bridges, tunnels, and overpasses. They are usually located on both sides of the bridge or around the piers. Their function is to reduce the impact force when a vehicle accident occurs, protect the bridge structure and driving safety. Crash barriers are usually made of concrete, reinforced concrete, or steel.

[0003] A road and bridge crash pier that is easy to install with the authorization announcement number CN218712494U discloses that a flexible steel plate is provided so that it is convenient to wrap it around the surface of the road and bridge, and a fixing plate and bolts are provided so that the flexible steel plate can be fixed and installed conveniently.

[0004] The above-mentioned device is divided into two layers, an inner and an outer layer, and springs are laid between the inner and outer layers to absorb impact force. However, the structure of the inner and outer layers is complex. Although many springs are used to absorb impact force, it is difficult to effectively ensure the connection strength between the parts and components. When receiving a strong impact, it is easy to cause the springs and other parts to fly off, which is quite dangerous. Therefore, in response to this situation, the utility model proposes a new solution. Utility Model Content

[0005] The purpose of the utility model is to provide a road bridge anti-collision pier to solve the problems raised in the above background technology.

[0007] Anti-collision frame;

[0008] At least two anti-collision frames are provided, the two anti-collision frames are fixed to each other, a plurality of inner frames are installed inside the anti-collision frame, and a plurality of anti-collision plates are fixed outside the anti-collision frame.

[0009] Further to this solution, the anti-collision frame includes a patch and an outer baffle, and the patch and the outer baffle are fixed at both ends by a connecting plate, wherein the surface of the patch is arc-shaped and fits the surface of the road pier.

[0010] Further to this solution, a buffer zone is formed between the patch and the outer baffle, and a plurality of inner frames are installed in the buffer zone of each anti-collision frame, and reinforced concrete is poured in the inner frames.

[0011] Further to this solution, one side of the inner frame is fixed to the inner wall surface of the outer baffle, and the other side of the inner frame is fixed to the patch. The top of the inner frame is open and the bottom is sealed.

[0012] Further to this solution, a plurality of bolt holes are provided on the two connecting plates of each of the anti-collision frames, and the anti-collision frames are connected to each other via fixing screws arranged in the bolt holes.

[0013] Further to this solution, the anti-collision plate is in an arc shape, is fixed to the outer wall surface of the anti-collision frame by bolts, and is equidistantly arranged outside the anti-collision frame.

[0014] Further to this solution, the inner frames are equidistantly arranged inside each corresponding anti-collision frame, and a spacing is provided between adjacent inner frames, and the thickness of the plate body constituting the anti-collision frame (and the inner frame) is ≤5 cm.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The road and bridge crash pier is equipped with a crash frame, an inner frame and a crash plate. The installation of the crash pier is simpler than the traditional construction method. It only requires the crash frame to be fixed by screws, and then reinforced concrete is poured into the inner frame. There is no need to support the formwork and then dismantle the formwork. This makes the crash pier have good energy absorption and buffering effects while having a high degree of stability. Compared with traditional crash piers, it also has a better protection effect on vehicles.

[0017] At the same time, even after the installation and construction of the road bridge crash pier, if it is damaged by impact, as long as the road pier itself is not damaged, the crash frame can be replaced to facilitate maintenance. Since it is still supported by reinforced concrete, its strength is also guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: Figure 1-Figure 3 As shown, the utility model provides a technical solution: a road and bridge crash pier, including a crash frame 2, two crash frames 2 are provided, the two crash frames 2 are fixed to each other, a plurality of inner frames 3 are installed inside the crash frame 2, a plurality of crash plates 4 are fixed outside the crash frame 2, the crash frame 2 is wrapped and installed on the surface of the road pier 1, the crash frame 2 increases the strength of the crash frame 2 by the structure of the inner frame 3 and the addition of engineering materials, and improves the crash prevention effect, and the disassembly and splicing method of the crash frame 2 facilitates the installation process.

[0024] like Figure 2 As shown, in order to ensure the smooth implementation of this embodiment, it is necessary to know that the anti-collision frame 2 includes a patch 201 and an outer baffle 202, and the patch 201 and the outer baffle 202 are fixed at both ends by a connecting plate 203, wherein the surface of the patch 201 is arc-shaped and fits the surface of the road pier 1, which facilitates the connection between the anti-collision frame 2 and the road pier 1 body, and the anti-collision frames 2 are connected and fixed and cooperate with the road pier 1 to form a anti-collision pier.

[0025] like Figure 2 As shown, in order to ensure the smooth implementation of this embodiment, it is necessary to know that a buffer zone is formed between the patch 201 and the outer baffle 202, and a plurality of inner frames 3 are installed in the buffer zone of each anti-collision frame 2, and reinforced concrete is poured in the inner frame 3.

[0026] As shown in the figure, in embodiment 1: the outer baffle 202 of the anti-collision frame 2 is a polygonal plate, which can be regarded as composed of multiple plates connected together. Under this structure, it is easy to produce the inner frame 3 and allow the inner frame 3 to fit the inner wall of the anti-collision frame 2, and then weld and fix it.

[0027] Embodiment 2: The outer baffle 202 of the anti-collision frame 2 is a semicircular plate, which can be formed by integral die-casting. The two sides of the inner frame 3 are respectively attached to the inner wall of the outer baffle 202 and the surface of the patch 201, so that the inner frame 3 is attached to the inner wall of the anti-collision frame 2 and fixed by welding.

[0028] like Figure 1 and Figure 2As shown, to ensure the smooth implementation of this embodiment, it is necessary to know that one side of the inner frame 3 is fixed to the inner wall surface of the outer baffle 202, and the other side of the inner frame 3 is fixed to the patch 201. The inner frame 3 is opened at the top and sealed at the bottom, forming a barrel-shaped structure.

The inner frames 3 are equidistantly arranged inside each corresponding anti-collision frame 2, and a spacing is set between adjacent inner frames 3. The thickness of the plates constituting the anti-collision frame 2 and the inner frame 3 is ≤5cm, so as to avoid the anti-collision frame 2 and the inner frame 3 being too thick and too strong to cause greater damage to the vehicle. At the same time, after the anti-collision frame 2 receives the impact, due to the gap between the inner frames 3, it has a certain deformation ability and can absorb energy well.

The fixing by the fixing screws 5 is simple and convenient. It is only necessary to insert the fixing screws 5 into the bolt holes 204 and then fix them with nuts. The operation is simple and convenient, and the construction is convenient. Even after the installation construction is completed, if it is damaged by impact, as long as the road pier 1 body is not damaged, the anti-collision frame 2 can be replaced, which is convenient for maintenance.
