Description

Technical Field

[0001] This invention relates to a guardrail, and more particularly to a repurposed, infill-type, anchor-free guardrail for use in road protection. Background Technology

[0002] With my country's rapid economic development and modernization, many old highways can no longer handle current passenger traffic. Furthermore, highway construction is costly and time-consuming, making widening and upgrading existing highways a mainstream approach. However, during road widening and upgrading, guardrails cannot be anchored to the road surface and must be easily repositioned. Ordinary guardrails, not anchored to the ground, offer virtually no crash protection. In this situation, the safety of construction workers is compromised. In the event of an accident, vehicles will directly collide with construction workers and equipment, causing significant injury to drivers and passengers, as well as construction workers, thus impacting construction progress. With the release of the new "Design Specifications / Detailed Rules for Highway Traffic Safety Facilities," the original double-wave steel guardrails no longer meet the requirements, resulting in a large number of double-wave beams being recycled as scrap after the upgrade. Summary of the Invention

[0003] In response to the aforementioned problems in the existing technology, such as the need for anchor-free guardrails in construction areas and the fact that double-wave beams can only be recycled as waste, this invention provides a reusable, infill-type anchor-free guardrail. This achieves the anchor-free effect by filling the mounting base with counterweights, and improves the utilization rate of the double-wave beams by applying them to the mounting base.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] An anchorless, reusable, filler-type guardrail includes a mounting base and a scrap guardrail. The mounting base has at least one post, and the scrap guardrail is placed on the post. The mounting base has a receiving space, which is filled with a counterweight. The mounting base has a filling inlet, which communicates with the receiving space.

[0006] Furthermore, the mounting base includes a base, the accommodating space is disposed within the base, an opening is provided above the base, a cover plate is provided over the opening, a filling inlet is disposed on the cover plate, a clearance opening is also provided on the cover plate, and the column is fixed on the base and passes through the clearance opening.

[0007] Furthermore, the scrap guardrail includes scrap beams, which are connected to the posts.

[0008] Furthermore, the waste beams are configured in two groups, with the two groups of waste beams respectively arranged opposite each other on both sides of the column. Both ends of the two groups of waste beams are provided with corrugated connectors, and the ends of the two groups of waste beams on the same side are connected to the same corrugated connector.

[0009] Furthermore, the base is provided with at least one drainage groove.

[0010] Furthermore, the side wall of the drainage trough is provided with a discharge port, and the discharge port is provided with a sealing plug.

[0011] Furthermore, the column is installed on the bottom wall of the drainage trough.

[0012] Furthermore, the base is configured as a plurality of bases, which are connected end to end in series.

[0013] Furthermore, it also includes a pin, both ends of the base are provided with grooves, the outer wall of the groove is provided with a plurality of first mounting parts, the first mounting parts are provided with first mounting holes, the wave connector is provided with a second mounting part, the second mounting part is provided with a second mounting hole, and the pin is inserted into the first mounting hole and the second mounting hole.

[0014] Furthermore, the filling inlet is provided with a sealing cap.

[0015] The beneficial effects of this invention are as follows: This invention provides a reusable, fill-in, anchor-free guardrail. By filling the mounting base with counterweights, the friction of the guardrail is increased, eliminating the need for drilling holes in the road surface for anchoring, thus achieving better protective effects. The upper crossbeam of the guardrail is made of double-wave steel, allowing for the reuse of scrap double-wave steel, improving material utilization. A drainage channel is provided at the bottom of the mounting base to drain rainwater. An outlet is provided on the side wall of the drainage channel for easy discharge of the counterweights. When there are no counterweights inside the mounting base, it can be easily transported and moved. The counterweights can be made of materials such as water and sand, making them easy to obtain and recycle. The mounting base itself is made of steel and is also recyclable. Two or more mounting bases can be detachably connected, allowing for easy connection into a whole. The guardrail can be opened at any staggered section, solving the problem of balancing the integrity of the guardrail connection with the flexibility of opening. Attached Figure Description

[0021] To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0022] Please see Figure 1-4 This invention provides a repurposed, fill-in, anchor-free guardrail, comprising a mounting base 1 and a discarded guardrail 2. The mounting base 1 has at least one upright post 3, and the discarded guardrail 2 is mounted on the upright post 3. The mounting base 1 has a accommodating space 4, which is filled with counterweights. The mounting base 1 has a filling inlet 121, which communicates with the accommodating space 4. In embodiments of this application, counterweights, such as water, sand, and stones—materials commonly found on construction sites—can be filled into the accommodating space 4 through the filling inlet 121, increasing the overall weight of the mounting base 1 and thus increasing the friction between the mounting base 1 and the ground, achieving a better protective effect. Of course, the counterweights can also be other dense and readily available materials, such as asphalt. It is understood that the higher the density of the counterweights, the better the protective effect of this application.

[0023] After testing, it was found that when the accommodating space 4 is filled with the aforementioned counterweight, the present application can achieve a protection level of B or higher without anchoring.

[0024] See Figure 2In some embodiments of this application, the mounting base 1 includes a base 11, and the accommodating space 4 is disposed within the base 11. An opening 111 is provided above the base 11, and a cover plate 12 is provided over the opening 111. The outer wall of the base 11 and the cover plate 12 form the accommodating space 4. For convenient filling, a filling inlet 121 is provided on the cover plate 12. Specifically, the number of columns 3 is set to three, and the three columns 3 can be evenly fixed to the bottom wall of the base 11 by welding. The cover plate 12 also has three corresponding clearance openings 122, through which at least a portion of the columns 3 can extend. The scrap guardrail 2 is installed on the portion of the columns 3 located outside the base 11. The columns 3 are made of steel pipe with specifications of 140*4.5*850 mm. To ensure strength, the base 11 and the cover plate 12 are made of steel.

[0025] Specifically, the waste guardrail 2 includes waste beams 21, which can be connected to the portion of the post 3 located outside the base 11 by means of connectors, such as fastening bolts.

[0026] Furthermore, the scrap beam slabs 21 are configured in two sets, with the two sets of scrap beam slabs 21 respectively positioned opposite each other on both sides of the column 3. Both ends of the two sets of scrap beam slabs 21 are provided with corrugated connectors 22, and the ends of the two sets of scrap beam slabs 21 on the same side are connected to the same corrugated connector 22. In this way, the two sets of scrap beam slabs 21 located on both sides of the column 3 are connected into a whole by the two corrugated connectors 22, which helps to improve the protective strength of the upper crossbeam. Preferably, the scrap beam slabs 21 are double-corrugated rigid beam slabs.

[0027] To prevent road flooding during rainy weather, the guardrails of this application include at least one drainage channel 13 on the base 11 in some embodiments. Rainwater can drain from the drainage channel 13, eliminating the impact of road flooding on driving safety.

[0028] See Figure 3 To facilitate the recycling of the counterweight, as an improvement on the above embodiment, this application provides a discharge port 131 on the side wall of the drainage trough 13, through which the counterweight can be discharged for easy recycling and reuse. After the counterweight is discharged from the discharge port 131, the overall weight of the mounting base 1 is reduced, facilitating its movement and transport.

[0029] To maintain the airtightness of the mounting base 1, the filling inlet 121 is provided with a sealing cap 123, and the outlet 131 is provided with a sealing plug 132. The sealing plug 132 can be connected to the outlet 131 by a threaded connection, which makes the connection between the two more secure.

[0030] See Figure 3 To save materials, as an improvement to the above embodiments, in some embodiments of this application, the column 3 is disposed on the bottom wall of the drainage trough 13. Since the drainage trough 13 has a certain depth, there is a height difference when the column 3 is disposed on the bottom wall of the drainage trough 13 compared to when the column 3 is disposed on the bottom wall of the base 11. Therefore, the length of the column 3 can be reduced accordingly, thereby achieving the purpose of saving materials.

[0031] See Figure 4 The base 11 is provided in multiple configurations, and the multiple bases 11 are connected end to end. Specifically, this application also includes a pin 5. Both ends of the base 11 are provided with grooves 112. The outer wall of the groove 112 is provided with multiple first mounting portions 113. The first mounting portions 113 extend outward from the grooves 112 at least partially, and the outwardly extending portions of the first mounting portions 113 match the grooves 112 on the ends of adjacent bases 11. The first mounting portions 113 are provided with first mounting holes 114. The wave connector 22 is provided with second mounting portions 221, and the second mounting portions 221 are provided with second mounting holes 222. When two bases 11 are connected end to end, the pin 5 is inserted into the first mounting holes 114 and the second mounting holes 222 for locking. To open a section of the guardrail, simply pull the corresponding pin 5 out of the first mounting hole 114 and the second mounting hole 222 to unlock it. This allows the guardrail to be opened in any staggered position, solving the problem of balancing the integrity of the guardrail connection with the flexibility of opening.

[0032] This invention provides a reusable, fill-in, anchor-free guardrail. By filling the mounting base 1 with counterweights, the friction of the guardrail is increased, eliminating the need for drilling holes in the road surface for anchoring and achieving better protective effects. The upper crossbeam of the guardrail is made of double-wave steel, allowing for the reuse of scrap double-wave steel and improving material utilization. A drainage channel 13 is provided at the bottom of the mounting base 1 to drain rainwater. An outlet 131 is provided on the side wall of the drainage channel 13 for easy discharge of the counterweights. When the mounting base 1 is empty, it can be easily transported and moved. The counterweights can be made of materials such as water or sand, making them easy to obtain and recycle. The mounting base 1, made of steel, is also recyclable. Two or more mounting bases 1 can be detachably connected, allowing for easy integration into a whole. The guardrail can be opened at any staggered interval, solving the problem of balancing the integrity of the guardrail connection with the flexibility of opening.

[0033] It should be understood that the application of the present invention is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
