Energy-absorbing flexible guard board

Abstract

The invention discloses an energy-absorbing flexible guard board. Especially, a plurality of wireropes (1) are intertwined to form a latticed wirerope net (2), the wirerope net (2) is wrapped by a compact plastic material to form a composite board (3), at least more than three steel wires are twisted to form one wirerope (1), and any two adjacent wireropes (1) are intertwined at an interval to form knots (4) of the latticed wirerope net (2). The energy-absorbing flexible guard board is suitable for impact protection of various static objects and moving objects, and is especially suitable for serving as a highway protection plate, and has especially-dramatic effect, and can serve as an upgrade product of the highway protection plate.

Description

Technical field: [0001] The invention relates to an anti-collision guard plate which can be used in various occasions, in particular to a flexible anti-collision guard plate with large deformation and good impact energy absorption. Background technique: [0002] With the progress and development of society, the increasingly motorized means of transportation, the use of various moving objects such as vehicles or ships is very common, and there are more and more collisions between motor objects and other fixed objects, such as motor vehicle traffic Accidents have increased significantly in recent years, causing a considerable number of casualties, or when a large number of ships of various sizes shelter from the wind during normal navigation or typhoons, a large number of ship-to-ship or ship-to-wharf collision accidents occurred, resulting in Quite a huge property loss and casualties. What needs to be pointed out in particular is that there are more and more expressways in o...

AI Technical Summary

Problems solved by technology

Because the isolation anti-collision (protection) device on both sides or in the middle of the existing expressway is to arrange a pile at a distance, a guard plate is set between two adjacent piles, and the guard plate two ends are fixed with the pile, and the guard plate According to the national standard, it is a galvanized steel plate with a thickness of 4mm. This steel plate has considerable strength and elasticity. According to the statistics and analysis of a large number of traffic accidents by the highway management department, when the vehicle is a large or heavy-duty vehicle, the above-mentioned existing protection The device will basically be damaged by impact, but for a large number of small and medium-sized vehicles passing through, such as the vehicle speed is fast and the impact angle is large, the impact of the above-mentioned high-strength steel plate and the vehicle will often cause large deformation of the vehicle and cause casualties. If the impact angle is small, the high elasticity of the steel plate will cause the impacting vehicle to pop up to the other side, causing a secondary collision between the impacting vehicle and the vehicle behind it, resulting in a secondary accident or a series of collisions. This phenomenon occurs in rainy, foggy or Snow and ice are especially common

Therefore, there are obvious defects in the design requirements of the protective plate or protective device of the highway at present. In addition, the above-mentioned galvanized steel sheet will produce a large amount of pollution in the production process, and it will be polluted by air during long-term use. The galvanized protection is difficult to last. easy to corrode

How to reduce the impact intensity of the first impact and reduce the occurrence of the second impact is the key issue in reducing traffic accidents on the expressway. The solution to this problem undoubtedly has very high economic value and social significance (reducing casualties). In fact, in rivers or The above-mentioned problems also exist in the collision between ships along the coast or in the harbor, especially the front ends of the ships are pointed, and it is also prone to ship damage or casualties
