[0027] See also Figure 1-8 , the utility model provides a BIM-based municipal guardrail technology solution:

[0028] Embodiment 1

[0029] A municipal guardrail based on BIM, the existing municipal guardrail structure mainly includes: a base 1, a column 2, a guardrail 3 and a connecting piece 4, wherein the guardrail 3 includes an upper crossbar 3.1, a lower crossbar 3.2 and a plurality of vertical bars 3.3 connected between the upper crossbar 3.1 and the lower crossbar 3.2; the base 1 is fixed to the road surface by bolts, the column 2 is inserted into the base 1, the top and bottom of the side wall of the column 2 are fixed with connecting pieces 4, the upper crossbar 3.1 and the lower crossbar 3.2 are horizontally arranged at both ends, respectively inserted into the connecting pieces 4 on the two columns 2, and fixed by screws, so that the guardrail 3 is not easy to be quickly removed from the connecting piece 4, and other vehicles cannot be quickly evacuated or emergency avoidance after a traffic accident occurs; therefore, the present application scheme is improved based on the existing structure, with the purpose of being able to modify the existing municipal guardrail structure and reduce the production cost.

[0030] In order to realize the rapid installation and removal of the fence 3 on the connecting piece 4, the specific improvement scheme is as follows:

[0031] Part of the end face of the connecting member 4 away from the column 2 is in a "冂" - shaped structure, and a rectangular through - slot 4.1 is provided on the upper surface; a limiting slot 4.2 for inserting the limiting plate 5 is horizontally provided along the inner edge of the bottom of the connecting member 4. The limiting plate 5 is horizontally inserted into the limiting slot 4.2 of the connecting member 4. The limiting plate 5 is inserted into the connecting member 4 to form a slot 45 in a "口" - shaped structure, so that the ends of the upper cross - bar 3.1 and the lower cross - bar 3.2 are exactly inserted into the slot 45, and rectangular clamping grooves 6 are provided on the upper surfaces of the two horizontally - arranged ends of the upper cross - bar 3.1 and the lower cross - bar 3.2.

[0032] The locking member 7 is in an "工" - shaped structure, and the side face of the folded locking member 7 is in a "√" - shaped structure, so that both ends of the locking member 7 are placed above the rectangular through - slot 4.1. One end of the upper surface of the connecting member 4 away from the column 2 is hinged to one end of the locking member 7. The middle of the locking member 7 is movably clamped in the rectangular clamping groove 6, so that the upper cross - bar 3.1 and the lower cross - bar 3.2 on the railing piece 3 can be quickly installed on the connecting member 4.

[0033] A drainage groove 5.1 is provided in the middle of the limiting plate 5 for draining rainwater. The vertical rod 3.3 is a square steel or a round rod. A reflector 9 is fixedly provided on the column 2 to remind the driver to pay attention to road signs and road conditions. Especially at night or in low - visibility conditions, the reflector can increase the visibility during driving, reduce the blind spots of oncoming vehicles, and avoid traffic accidents.

[0034] The working principle is as follows: When a traffic accident occurs and there is a traffic jam, in order to quickly let the ambulance enter the accident scene in the first time, it is only necessary to manually pull out the limiting plate 5 in the limiting slot 4.2, so that the upper cross - bar 3.1 and the lower cross - bar 3.2 on the railing piece 3 can quickly fall down from the connecting member 4, which is convenient for vehicles or medical staff to enter or leave. Then, reverse the operation to reinstall the railing piece 3 into the connecting member 4.

[0035] At the same time, when installing the municipal guardrail on a new section of the road, the installation form is basically the same as the existing installation method of the municipal guardrail. The only difference is that the limiting plate 5 is directly inserted into the limiting slot 4.2 in advance, and the two ends of the upper cross - bar 3.1 and the lower cross - bar 3.2 on the railing piece 3 are directly inserted into the slot 45. After insertion, the locking member 7 will automatically fall into the rectangular clamping groove 6, so that the railing piece 3 is locked by the locking member 7 and cannot be pulled out; realizing the quick installation and disassembly of the railing piece 3 on the connecting member 4.

[0036] Embodiment Two

[0037] Please refer to Figure 8Compared with the first embodiment, the overall structures of the second embodiment are basically the same. The difference between the two is that when the vertical rod 3.3 is a round rod, a round tube 8 is sleeved on the outer surface of the vertical rod 3.3. If a vehicle hits the guardrail, the rotation of the round tube 8 can be used to reduce the mutual impact force between the vehicle and the guardrail, thereby avoiding accidents as much as possible.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
