Description

Technical Field

[0001] The present application relates to the technical field of metal guardrails, and in particular to a spliced ​​metal guardrail. Background Art

[0002] Currently, most common guardrails are connected into an integral structure by welding or bolts, especially the vertical bars in the guardrails, which are mostly fixedly connected to the cross bars or plugged into the cross bars. Metal guardrails usually placed on the road are damaged in collisions, mostly single or multiple vertical bars are damaged, and need to be replaced after damage, so the guardrail needs to be pulled away for repair. However, this is not the case with spliced ​​metal guardrails, because they are fixed by splicing, so only individual components need to be replaced after the components are damaged.

[0003] Compared with the existing spliced ​​metal guardrails in actual use, one of the guardrails with higher height and longer length is fixed by splicing and assembly, but due to its large size, the volume of its individual parts is also large, which makes the transportation of the guardrail after disassembly very difficult. Due to the long length or high height, many guardrail parts cannot be placed in the car at one time, which reduces the practicality of the guardrail.

[0004] Therefore, in order to solve the above problems, the present application provides a spliced ​​metal guardrail.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0008] Preferably, a fixed limiter is installed at the connection between the bottom support frame and the top support frame, and the fixed limiter is a bolt limiter.

[0009] Preferably, a plurality of guardrail rods are slidably embedded in corresponding ends of the guardrail top rail and the guardrail bottom rail.

[0010] Preferably, a fixing rod is embedded in the outer side of one end of the embedding groove seat, penetrating through the embedding groove seat and the connecting rod.

[0011] Preferably, a fitting block is welded on the outer side of one end of the top support frame, and a folding groove is provided on the outer side of one end of the bottom support frame.

[0012] Preferably, the engaging block is engaged with the folding groove.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. By setting the support frame into a foldable bottom support frame and a top support frame, the support frame can save more space in transportation after disassembly. The guardrail is installed and placed using the top rail and the bottom rail, which makes the guardrail more space-saving and realizes the splicing and folding function of the guardrail. Compared with the existing technology, it has the advantages of adjustable height, small footprint and simple splicing process. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Reference Figure 1-Figure 3A spliced ​​metal guardrail includes a support seat 1, a card-embedded groove seat 2 is welded on the top of the support seat 1, a connecting rod 3 is embedded in the inner side of the card-embedded groove seat 2, a bottom support frame 4 is welded on the top of the connecting rod 3, and the top of the bottom support frame 4 is card-embedded and connected to the top support frame 5, and a plurality of card-embedded plates 6 are welded on both sides of the top support frame 5 and the bottom support frame 4. The outer side of the card-embedded plate 6 is sequentially card-embedded with a guardrail top rail 8 and a guardrail bottom rail 13 from top to bottom. In order to facilitate the removal and assembly of the guardrail railing, a connecting rod 9 is welded on the top of the guardrail top rail 8 and the bottom of the guardrail bottom rail 13. A card plate 10 is sleeved on the outer side of the connecting rod 9, and the top of the card plate 10 is connected to the connecting rod 9. A fixing nut 11 is sleeved on the outside.
