Description

Technical Field

[0001] The utility model relates to the technical field of construction guardrails, in particular to an anti-collision guardrail for municipal engineering. Background Art

[0002] With the development of social construction, it is usually necessary to separate public areas and temporary construction areas during the construction of municipal engineering projects to ensure that the roads can be driven normally and the construction workers can work normally. Therefore, guardrails are used to separate the two areas, give people information prompts, and provide safety protection for pedestrians and vehicles.

[0003] In the prior art anti-collision guardrails used in municipal engineering construction, the guardrails are usually fixed structures as a whole, while the road construction site is of uncertain size, which greatly restricts the placement of the guardrails and makes it difficult to adjust the overall guardrail according to the required site size, thereby affecting its overall protection range and applicability.

[0004] In the prior art, a Chinese patent with the announcement number CN218862262U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: an anti-collision guardrail for municipal engineering construction, including a main column, a side plate is provided on one side of the main column, and a guardrail mechanism is provided on the side of the connection between the main column and the side plate, and the guardrail mechanism includes a connecting column, the connecting column is located on the side of the side plate facing the main column, and the end of the connecting column away from the side plate is fixedly connected to the side wall of the main column, and the inner cavity of the end of the connecting column facing the side plate is provided with a built-in groove. Through the set guardrail mechanism, the connecting column and the movable column provided inside it can be used to respectively connect with the main column and the side plate, and cooperate with the provided built-in groove to facilitate effective stretching between the connecting column and the movable column, and the provided anti-slip metal sheet, fastening bolts, arm rods, and fixed blocks are used to play a good positioning role between the connecting column and the movable column, thereby indirectly achieving the benefit of effective adjustment of the overall guardrail protection length.

[0005] In the above technical solution, no buffer structure is provided on the outside of the guardrail, which cannot play a buffering role in the event of an accident and cannot reduce the damage and economic losses caused by the accident. Utility Model Content

[0013] A further improvement of the technical solution of the utility model is that the outer wall of the positioning block is plugged into the inner wall of the positioning groove.

[0014] By adopting the above technical solution, when the anti-collision plate group needs to be assembled, its two ends are first docked with the docking grooves, and then lowered, and the positioning blocks are docked with the positioning grooves. Then the staff can use the installation screws to fix the anti-collision plate group on the supporting barrier plate, thereby completing the installation work. The anti-collision plate group can be removed by the opposite operation.

[0018] A further improvement of the technical solution of the utility model is that: both ends of the buffer elastic plate are fixedly connected to one side of the built-in reinforcement plate.

[0019] A further improvement of the technical solution of the utility model is that one end of the buffer spring is fixedly connected to a side of the built-in reinforcement plate close to the external arc plate.

[0020] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] The present invention is further described in detail below in conjunction with the embodiments:

[0031] Example 1

[0032] like Figure 1-5 As shown, the utility model provides an anti-collision guardrail for municipal engineering, including a main column 1, a fixed sleeve 2 and an anti-collision plate group 3, a docking groove 10 is opened on one side of the fixed sleeve 2, and a supporting barrier plate 4 is fixedly connected to the inner wall of the main column 1.

[0033] The anti-collision plate group 3 includes an internal reinforcement plate 13 attached to one side of the supporting barrier plate 4, an external arc plate 12 fixedly connected to the side of the internal reinforcement plate 13 away from the supporting barrier plate 4, and a buffer spring 15 fixedly connected between the external arc plate 12 and the internal reinforcement plate 13. The inner wall of the external arc plate 12 is fixedly connected with a buffer elastic plate 14. When the guardrail is hit, the external arc plate 12, the buffer elastic plate 14 and the buffer spring 15 first receive the impact and then deform to absorb the impact force, thereby reducing the potential energy of the vehicle impact, reducing the impact and damage of the vehicle to pedestrians and drivers, and thus reducing the danger after the accident.

[0034] The interior of the support baffle plate 4 is fixedly connected with a transversely distributed transverse reinforcing strip 9, and the outer wall of the fixed sleeve 2 is fixedly connected with a rubber protective sleeve layer 11. The rubber protective sleeve layer 11 sleeved on the outer wall of the fixed sleeve 2 can also play a buffering role to a certain extent.

[0035] Example 2

[0036] like Figure 1-5As shown, based on Example 1, the utility model provides a technical solution: preferably, a positioning block 5 is fixedly connected to the upper surface of the anti-collision plate group 3, and a positioning groove 7 for receiving the positioning block 5 is fixedly connected to the upper surface of the supporting blocking plate 4.

[0037] The outer wall of the positioning block 5 is plugged into the inner wall of the positioning groove 7, and one end of the anti-collision plate group 3 is plugged into the inner wall of the docking groove 10. When the anti-collision plate group 3 needs to be assembled, its two ends are first docked with the docking groove 10, and then lowered, and the positioning block 5 is docked and locked with the positioning groove 7. Then the staff can use the installation screws 6 to fix the anti-collision plate group 3 on the supporting barrier plate 4, thereby completing the installation work. The anti-collision plate group 3 can be removed by the opposite operation.

[0038] Example 3

[0039] like Figure 1-5 As shown, based on Example 1, the utility model provides a technical solution: preferably, a screw mounting hole 8 is opened on one side of the supporting barrier plate 4, a threaded hole is opened at one end of the built-in reinforcement plate 13, and the inner wall of the threaded hole is threadedly connected with a mounting screw 6, and one end of the mounting screw 6 passes through the threaded hole to the inside of the screw mounting hole 8.

[0040] Both ends of the buffer elastic plate 14 are fixedly connected to one side of the built-in reinforcement plate 13 , and one end of the buffer spring 15 is fixedly connected to one side of the built-in reinforcement plate 13 close to the external arc plate 12 .

[0041] Let's talk about the working principle of the anti-collision guardrail used in municipal engineering projects.

[0042] like Figure 1-5 As shown, when in use, when the guardrail is hit, the external arc plate 12, the buffer elastic plate 14 and the buffer spring 15 first receive the impact and then deform to absorb the impact force, reduce the potential energy of the vehicle impact, reduce the impact and damage of the vehicle to pedestrians and drivers, thereby reducing the danger after the accident.

[0043] At the same time, the rubber protective sleeve layer 11 sleeved on the outer wall of the fixed sleeve 2 can also play a buffering role to a certain extent.

[0044] When the anti-collision plate group 3 needs to be assembled, its two ends are first docked with the docking grooves 10, and then lowered, and the positioning block 5 is docked with the positioning groove 7. Then the staff can use the installation screws 6 to fix the anti-collision plate group 3 on the supporting barrier plate 4, and then complete the installation work. The anti-collision plate group 3 can be removed by the reverse operation.

[0045] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
