Pipe racks are sleeved at both ends of the handrail. Pillars are fixed at the bottom of the pipe racks. Mounting seats are fixed on the outer walls on both sides of the pillars. Mounting openings are formed on the outer walls on both sides of the pillars. Two crossbars are provided between the two pillars on both sides. Mounting heads are fixed at both ends of the crossbars. Brackets are fixed inside the mounting heads. Sleeve racks are fixed on both sides inside the brackets. Symmetrically opposite pin heads are slidably connected inside the two sleeve racks. Guide rods are provided inside the brackets. Sleeve bushes are sleeved at both ends of the guide rods. First struts and second struts are rotatably connected to the outer walls on both sides of the sleeve bushes, which solves the problems that the installation of the existing bridge guardrail is too cumbersome, a large number of bolts are required for fixing each group of guardrails during assembly, which takes a lot of time, and some bridge guardrails are mostly installed by welding. Although the welded guardrails have strong stability, they are more troublesome to disassemble and assemble.

[0003] Only two crossbars are provided in the middle of the two pillars of the above technology, and they are installed on the pillars through the mounting heads. In this way, when a vehicle collision occurs, only the two crossbars cannot bear the impact of the vehicle and thus cannot play the protective role of the guardrail. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcoming that in the prior art, when a vehicle collision occurs, only two crossbars cannot bear the impact of the vehicle and thus cannot play the protective role of the guardrail, and a new type of guardrail with high strength and corrosion resistance is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: A new type of guardrail with high strength and corrosion resistance, including two pillars. Plug holes are provided on the surfaces of the two pillars. A first reinforcing rod is provided in the middle of the two pillars.

Four jacks are provided on the surfaces of the first reinforcing rod and the second reinforcing rod. Four fixing holes are provided on the surface of the first reinforcing rod. Pin shafts are provided on one side of each of the four fixing holes. Three warning strips are provided on one side of the first reinforcing rod and the second reinforcing rod. Two mounting brackets are provided on the surfaces of both ends of the first reinforcing rod and the second reinforcing rod. Four reinforcing ribs are provided in the middle of the two pillars. Top covers are provided on the top surfaces of the four reinforcing ribs.

[0006] Preferably, the vertical central axes of the pin holes on the surfaces of the two pillars are consistent, and the pin holes penetrate through the pillars. The pillars are fixed to the ground by four expansion screws. Six of the warning strips are evenly pasted on the surfaces of the first reinforcing bar and the second reinforcing bar in groups of three.

[0007] Preferably, four of the pin blocks are evenly arranged on the surfaces of the first reinforcing bar and the second reinforcing bar. The first reinforcing bar is integrally formed with two of the pin blocks, and the second reinforcing bar is integrally formed with two of the pin blocks.

[0008] Preferably, four of the mounting brackets on the surfaces of the first reinforcing bar and the second reinforcing bar are evenly arranged at both ends of the first reinforcing bar and the second reinforcing bar in groups of two with consistent vertical central axes. The first reinforcing bar and the second reinforcing bar are both integrally formed with the mounting brackets.

[0009] Preferably, the first reinforcing bar and the second reinforcing bar are perpendicular to each other, and the pin blocks on both sides of the first reinforcing bar and the second reinforcing bar are installed in the pin holes of the two pillars.

[0010] Preferably, the four jack holes on the top surfaces of the first reinforcing bar and the second reinforcing bar penetrate through the first reinforcing bar and the second reinforcing bar at an inclination of 20 degrees.

[0012] Preferably, anti-corrosion coatings are applied to the surfaces of the two pillars, the first reinforcing bar, the second reinforcing bar, the four reinforcing ribs, and the four pin shafts.

[0013] Beneficial effects

[0014] In the present utility model, a part of the convex blocks is added to one side of each of the first reinforcing bar and the second reinforcing bar, so that the cross-sections of the first reinforcing bar and the second reinforcing bar are larger than those of the existing cylindrical and rectangular guardrails. The impact resistance of the whole is increased by adding convex blocks to the first reinforcing bar and the second reinforcing bar. Four of the reinforcing ribs are installed in the jack holes on the top surfaces of the convex blocks of the first reinforcing bar and the second reinforcing bar, and the reinforcing ribs are fixed in the jack holes with pin shafts, so that the reinforcing ribs and the first reinforcing bar and the second reinforcing bar are in an alternating state, thereby effectively dispersing the impact force and reducing the pressure on the concentrated stress points, thereby enhancing the stability of the overall structure, and solving the defect that when a vehicle collision occurs, only two cross bars cannot withstand the impact of the vehicle and thus cannot play the protective role of the guardrail.

[0026] The following describes the specific embodiments of the present utility model with reference to the drawings. Specific Embodiment 1:

[0028] Refer to Figures 1-4, a new type of high-strength and corrosion-resistant guardrail, including two pillars 1. The surfaces of both pillars 1 are provided with pin holes 8. A first reinforcing rod 2 is arranged between the two pillars 1. A second reinforcing rod 3 is arranged at the top of the first reinforcing rod 2. Pin blocks 9 are arranged on both sides of the first reinforcing rod 2 and the second reinforcing rod 3. Four jack holes 11 are arranged on the surfaces of the first reinforcing rod 2 and the second reinforcing rod 3. Four fixing holes 10 are arranged on the surface of the first reinforcing rod 2. A pin shaft 12 is arranged on one side of each of the four fixing holes 10. Three warning strips 7 are arranged on one side of both the first reinforcing rod 2 and the second reinforcing rod 3. Two mounting brackets 6 are arranged on the end surfaces of both ends of the first reinforcing rod 2 and the second reinforcing rod 3. Four reinforcing ribs 4 are arranged between the two pillars 1. A top cover 5 is arranged on the top surfaces of the four reinforcing ribs 4. The vertical central axes of the pin holes 8 on the surfaces of the two pillars 1 are the same, and the pin holes 8 penetrate through the pillars 1. The pillars 1 are fixed to the ground by four expansion screws. Six warning strips 7 are evenly pasted on the surfaces of the first reinforcing rod 2 and the second reinforcing rod 3 in groups of three. Four pin blocks 9 are evenly arranged on the surfaces of the first reinforcing rod 2 and the second reinforcing rod 3. The first reinforcing rod 2 is integrally formed with the two pin blocks 9, and the second reinforcing rod 3 is integrally formed with the two pin blocks 9. Four mounting brackets 6 on the surfaces of the first reinforcing rod 2 and the second reinforcing rod 3 are evenly arranged at both ends of the first reinforcing rod 2 and the second reinforcing rod 3 in groups of two with the same vertical central axis, and both the first reinforcing rod 2 and the second reinforcing rod 3 are integrally formed with the mounting brackets 6. The first reinforcing rod 2 and the second reinforcing rod 3 are in a vertical state, and the pin blocks 9 on both sides of the first reinforcing rod 2 and the second reinforcing rod 3 are installed in the pin holes 8 of the two pillars 1. The four jack holes 11 on the top surfaces of the first reinforcing rod 2 and the second reinforcing rod 3 penetrate through the first reinforcing rod 2 and the second reinforcing rod 3 obliquely at an angle of 20 degrees, and the four reinforcing ribs 4 are installed in the jack holes 11 of the first reinforcing rod 2 and the second reinforcing rod 3. The four reinforcing ribs 4 are integrally formed with the top cover 5. The four fixing holes 10 are arranged on the surface of the first reinforcing rod 2, and the positions where the fixing holes 10 are arranged are parallel to the jack holes 11 on the top surface of the first reinforcing rod 2. The four pin shafts 12 are all installed in the fixing holes 10 and penetrate through the reinforcing ribs 4 installed in the jack holes 11 on the top surface of the first reinforcing rod 2. Anti-corrosion coatings are applied on the surfaces of the two pillars 1, the first reinforcing rod 2, the second reinforcing rod 3, the four reinforcing ribs 4, and the four pin shafts 12.

[0029] Two struts 1 are fixed to the ground by four expansion bolts. The struts 1 are used to install the first reinforcing bar 2 and the second reinforcing bar 3. The first reinforcing bar 2 and the second reinforcing bar 3 are installed in two pin holes 8 on the surface of the struts 1 through pin blocks 9 on the left and right side surfaces, so that the first reinforcing bar 2 and the second reinforcing bar 3 are installed on the struts 1 through the pin blocks 9, and the two mounting brackets 6 on the two end surfaces of the first reinforcing bar 2 and the second reinforcing bar 3 are attached to the surfaces of the two struts 1, and fixing bolts are passed through the mounting brackets 6 of the first reinforcing bar 2 and the second reinforcing bar 3 to fix the first reinforcing bar 2 and the second reinforcing bar 3 on the struts 1, preventing the first reinforcing bar 2 and the second reinforcing bar 3 from falling off when being impacted. A part of bumps is added to one side of the first reinforcing bar 2 and the second reinforcing bar 3, so that the cross-section of the first reinforcing bar 2 and the second reinforcing bar 3 is larger than the cross-sections of the existing cylindrical and rectangular guardrails. By adding bumps to the first reinforcing bar 2 and the second reinforcing bar 3, the width of the first reinforcing bar 2 and the second reinforcing bar 3 is increased, thereby improving the compressive resistance and protection effect of the guardrail. The installed first reinforcing bar 2 and second reinforcing bar 3 play a role in protecting both sides of the road and intercepting out-of-control vehicles, preventing the out-of-control vehicles from rushing towards the pedestrians on both sides of the road. Three warning strips 7 are also pasted on the surfaces of the first reinforcing bar 2 and the second reinforcing bar 3. The material of the warning strips 7 is based on microprism retroreflective technology, which can effectively reflect light when irradiated by light, reminding the driver to pay attention to the road conditions ahead, especially at night or in low-light conditions. Four reinforcing ribs 4 are installed in four jacks 11 on the top surfaces of the bumps of the first reinforcing bar 2 and the second reinforcing bar 3. Since the jacks 11 of the first reinforcing bar 2 and the second reinforcing bar 3 are inclined at 20 degrees, when the reinforcing ribs 4 are installed in the jacks 11 of the first reinforcing bar 2 and the second reinforcing bar 3, the reinforcing ribs 4 will also be inclined at 20 degrees. When the reinforcing ribs 4 are installed, the top covers 5 on the top surfaces of the reinforcing ribs 4 will be stuck on the top surface of the second reinforcing bar 3, so that the reinforcing ribs 4 are stuck in the jacks 11 of the first reinforcing bar 2 and the second reinforcing bar 3, facilitating the fixing of the reinforcing ribs 4 with a pin 12. By installing the reinforcing ribs 4 in a mesh shape with the first reinforcing bar 2 and the second reinforcing bar 3, the structural strength of the first reinforcing bar 2 and the second reinforcing bar 3 is increased, the pressure resistance and impact resistance are improved, the anti-extrusion ability and strength of the guardrail are ensured, and four pins 12 are passed through four fixing holes 10 on the surface of the first reinforcing bar 2 and penetrate the bottom ends of the four reinforcing ribs 4 to fix the reinforcing ribs 4 in the jacks 11 and fix the reinforcing ribs 4 on the first reinforcing bar 2 and the second reinforcing bar 3, so that after installation, the reinforcing ribs 4 of the guardrail and the first reinforcing bar 2 and the second reinforcing bar 3 are in a mesh state, thereby effectively dispersing the impact force and reducing the pressure at the concentrated stress points, thereby enhancing the stability of the overall structure. Anti-corrosion coatings are applied to the surfaces of the two struts 1, the first reinforcing bar 2, the second reinforcing bar 3, the four reinforcing ribs 4, and the four pins 12. A protective layer is covered on the surfaces of the two struts 1, the first reinforcing bar 2, the second reinforcing bar 3, the four reinforcing ribs 4, and the four pins 12. The coating can be paint, plastic coating, metal plating, etc.To isolate the metal from contact with the corrosive medium, reduce the corrosion of the guardrail, and endow the guardrail with not only high strength but also corrosion resistance. Specific Embodiment 2:

[0031] Refer to Figures 1-8 For a new type of high-strength and corrosion-resistant guardrail, further based on the basic structure in Specific Embodiment 1, four pin shafts 12 can be provided on one side of each of the two columns 1. When the insertion blocks 9 of the first reinforcing rod 2 and the second reinforcing rod 3 are installed in the insertion holes 8 of the two columns 1, the pin shafts 12 can be installed into the interiors of the two columns 1 and penetrate through the insertion blocks 9 of the first reinforcing rod 2 and the second reinforcing rod 3, so that the first reinforcing rod 2 and the second reinforcing rod 3 are more firmly fixed on the two columns 1.

[0032] In summary:

[0033] 1. Add a part of protrusions on one side of the first reinforcing rod 2 and the second reinforcing rod 3, so that the cross-sections of the first reinforcing rod 2 and the second reinforcing rod 3 are larger than those of the existing cylindrical and rectangular guardrails. Increase the overall impact resistance by adding protrusions to the first reinforcing rod 2 and the second reinforcing rod 3, and install the four reinforcing ribs 4 in the insertion holes 11 on the top surfaces of the protrusions of the first reinforcing rod 2 and the second reinforcing rod 3, and fix the reinforcing ribs 4 in the insertion holes 11 with the pin shafts 12, so that the reinforcing ribs 4 and the first reinforcing rod 2 and the second reinforcing rod 3 are in an alternating state, thereby effectively dispersing the impact force and reducing the pressure at the concentrated stress points, thus enhancing the stability of the overall structure and solving the drawback that when a vehicle collision occurs, only the two cross bars cannot withstand the impact of the vehicle and thus cannot play the protective role of the guardrail.
