Description

Technical Field

[0001] The present invention relates to the technical field of glass fiber reinforced plastic guardrails, in particular to a glass fiber reinforced plastic road guardrail. Background Art

[0002] Fiberglass, also known as fiberglass reinforced plastics (FRP), is a fiber-reinforced composite plastic. Depending on the fiber used, it can be categorized as glass fiber reinforced composite plastic (GFRP), carbon fiber reinforced composite plastic (CFRP), and boron fiber reinforced composite plastic. It is a composite material using glass fiber and its products (glass cloth, tape, felt, yarn, etc.) as reinforcement and a synthetic resin as the matrix. Due to its excellent properties, including high temperature resistance, corrosion resistance, high strength, low specific gravity, low moisture absorption, low elongation, and excellent insulation, FRP has been widely used in recent years in industries such as the chemical industry, telecommunications, and construction.

[0003] Accordingly, FRP is widely used in the field of municipal construction due to its light weight, beautiful appearance, high strength and good quality, such as road guardrails. For example, the Chinese utility model with publication number CN217870191U discloses a FRP guardrail with an anti-collision function, including a FRP guardrail body, an anti-collision mechanism fixed inside the FRP guardrail body, the anti-collision mechanism including a guardrail post, a guardrail post fixed inside the FRP guardrail body, and a FRP guardrail first fixed block hinged to the surface of the guardrail post through a torsion spring, and a rubber sleeve fixed to the surface of the FRP guardrail first fixed block. The utility model is provided with a guardrail post and a FRP guardrail first fixed block, and the rubber sleeve makes the device more effective in anti-collision. When an object from the side hits the FRP guardrail first fixed block, the FRP guardrail first fixed block will rotate, and the FRP guardrail first fixed block will offset the force of rotation under the action of the torsion spring. Multiple groups of FRP guardrail first fixed blocks alleviate the force of the impact, making the device more secure.

[0004] However, the above-mentioned fiberglass guardrail only has the function of separating roads and preventing vehicles from hitting. In modern roads, green plants and guardrails are usually integrated into an organic whole. Therefore, a new type of fiberglass guardrail is needed that can effectively ensure the growth of green plants and also has sufficient anti-collision performance. Summary of the Invention

[0010] Furthermore, a vertical partition plate is provided on the baffle, and the partition plate divides the upper portion of the baffle into two independent areas, wherein the water leakage hole and the water outlet are respectively located in different areas.

[0011] Furthermore, the protective box is also provided with an inclined baffle in the receiving part. The baffle is arranged at an angle, and the inner wall of the long side of the protective box corresponding to the baffle is fixedly connected to the protective box. A water supply channel is provided between the position of the two end faces of the protective box corresponding to the baffle and the inner wall of the protective box.

[0012] Furthermore, the shield is a symmetrical bending structure, with the middle portion protruding upward and the two ends inclined downward.

[0013] Furthermore, several reinforcing plates are provided in the accommodating portion, which are perpendicular to the long side direction of the protective box.

[0023] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1:

[0025] like Figure 1As shown, an embodiment of the present invention provides a fiberglass road guardrail comprising a planter box 1 and a protective box 2, spaced apart from each other. The planter box 1 is a square box structure with an open top, while the protective box 2 is a strip-shaped box structure with an open top. Support legs 3 are provided at the four corners of the bottom of each of the planter box 1 and the protective box 2. In this embodiment, both the planter box 1 and the protective box 2 are made of fiberglass. The planter box 1 is filled with soil and planted with green plants, thereby forming a green belt.

[0026] The protective box 2 includes a receiving portion 21, a connecting portion 22 and a accommodating portion 23 arranged in sequence from top to bottom, wherein the receiving portion 21 and the accommodating portion 23 are both rectangular structures, and the receiving portion 21 is wider than the accommodating portion 23. The connecting portion 22 is a trapezoidal structure and connects the receiving portion 21 and the accommodating portion 23 up and down. The height of the plant box 1 is smaller than that of the protective box 2. One of the vertical end faces of the protective box 2 is tightly attached to and fixedly connected to the vertical end face of the plant box 1, and a water leakage hole 41 is provided on the end face of the protective box 2 at a position higher than the plant box 1, thereby corresponding to the upper position of the plant box 1. An openable and closable water outlet 7 is also provided at the bottom of the protective box 2, so that water can be released to reduce weight when it needs to be moved.

[0027] In this embodiment, a baffle 4 is provided at the position corresponding to the receiving portion 21 and the connecting portion 22 inside the protective box 2. The baffle 4 is arranged horizontally, and the leakage hole 41 is arranged at a height corresponding to the surface of the baffle 4 so as to be connected to the area above the baffle 4. The end of the baffle 4 corresponding to the leakage hole 41 completely closes the horizontal space inside the protective box 2 where it is located, and a water outlet is left between the end of the baffle 4 away from the leakage hole 41 and the corresponding inner wall of the protective box 2, so that water can pass through. In this way, after rainwater enters the protective box 2, it will be blocked by the baffle 4, and a part of it will enter the green plant box 1 through the leakage hole 41, and the other part will flow downward through the water outlet into the connecting portion 22 and the accommodating portion 23 for storage, and serve as a load and buffer filler for the protective box 2.

[0028] Furthermore, the baffle 4 is provided with a vertical partition 42, which divides the upper portion of the baffle 4 into two independent areas, with the drain hole 41 and the water outlet located in different areas. This creates a rainwater retention area near the drain hole 41 on the baffle 4, allowing water to continue to flow through the drain hole 41 to the planter box 1 after the rain stops. It should be noted that the drain hole 41 has an extremely small aperture, allowing rainwater to flow out only slowly, thereby maintaining a long-term water supply.

[0029] In this embodiment, the protective box 2 is further provided with an inclined shield 5 within the receiving portion 21. The shield 5 is tilted and fixedly connected to the inner wall of the protective box 2 corresponding to the long side of the shield 5. A water flow channel is provided between the shield 5 and the inner wall of the protective box 2 at the positions corresponding to the two end surfaces of the shield 5. The shield 5 forms a shielding structure in the upper area of ​​the protective box 2, preventing sunlight from entering the interior on sunny days and causing rainwater to evaporate rapidly. This maintains the retention of rainwater within the protective box 2, allowing it to properly maintain its buffering and collision avoidance functions. In addition, the shield 5 is a symmetrical curved structure, with the middle portion convex upward and the ends tilted downward. This provides greater symmetry, ensuring that the weight of rainwater entering the box is consistent on both sides.

[0030] In this embodiment, the housing portion 23 is preferably further provided with a plurality of reinforcing plates 6. The reinforcing plates 6 are perpendicular to the long sides of the protective box 2. The vertical end faces of the reinforcing plates 6 are fixedly connected to the inner wall of the protective box 2, and a gap is left between the bottom of the reinforcing plates 6 and the bottom surface of the protective box 2. The reinforcing plates 6 enhance the overall strength of the housing portion 23, preventing it from swelling or cracking due to internal water pressure caused by excessive rainwater under normal circumstances.

[0031] A protective plate 8 is also provided at the top opening of the protective box 2. The protective plate 8 is rotatably connected to the top edge of the protective box 2 in the longitudinal direction by a rotating shaft, and a torsion spring is provided on the rotating shaft. This allows the protective plate 8 to remain horizontal when not under force, and to rotate toward the interior of the protective box 2 when subjected to a downward impact force. The protective plate 8 can shield the top of the protective box 2 to prevent dust from entering and blockages. The protective plate 8 is made of lightweight plastic and weighs very little. When impacted by rain, it will rotate downward significantly without affecting the entry of rainwater.

[0032] Example 2:

[0033] The rest of this embodiment is identical to that of Example 1, except that the accommodating portion 23 does not include a reinforcing plate 6 but instead includes a buffer pad 9 having a honeycomb structure that does not interfere with the downward flow of water. The buffer pad 9 also serves to strengthen the protective plate 8 itself, and its honeycomb structure provides improved energy absorption and buffering when impacted by a vehicle.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
