Aluminum alloy corrugated plate-ECC plate combined anti-collision guardrail

Abstract

The invention discloses an aluminum alloy corrugated plate-ECC plate combined anti-collision guardrail which comprises an aluminum alloy corrugated plate, an ECC energy consumption plate, an L-shaped aluminum alloy support, aluminum alloy-concrete combined stand columns, connecting bolts, connecting screws and an embedded bearing platform. The lower ends of the aluminum alloy-concrete combined stand columns are connected with the embedded bearing platform through the connecting bolts. The upper ends of the aluminum alloy-concrete combined stand columns are connected with the ECC energy consumption plate through the L-shaped aluminum alloy support and the connecting bolts. According to the aluminum alloy corrugated plate-ECC plate combined anti-collision guardrail, first-stage impact energy consumption is carried out through the aluminum alloy corrugated plate; and the anti-impact rigidity of the aluminum alloy corrugated plate is improved through the ECC energy consumption plate, and meanwhile the impact energy is further dissipated through the ECC energy consumption plate. The mechanical properties of the aluminum alloy and the ECC concrete are reasonably utilized, and the concrete has the advantages of being high in durability, good in environmental protection performance, excellent in impact resistance, high in energy dissipation capacity, low in price, low in maintenance cost, capable of achieving rapid construction and replacement and the like.

Description

technical field [0001] The invention relates to an aluminum alloy corrugated plate-ECC plate combined anti-collision guardrail which has the advantages of excellent anti-collision performance, corrosion resistance, light weight, easy production and low cost, and belongs to the field of road safety engineering. Background technique [0002] Anti-collision barriers are widely used in highways. They are an important barrier to prevent irrelevant personnel and affairs from affecting road driving safety. They are also an important life support device when road accidents occur. Steel structure anti-collision barriers are currently widely used in highway anti-collision barriers. However, they have disadvantages such as easy corrosion, high maintenance costs, and large changes in impact resistance and energy consumption with the service cycle during use, and steel structure anti-collision barriers are commonly used Advanced spray paint anti-corrosion technology will seriously pollut...
