Problems solved by technology

[0003] In terms of safety island construction, most of the materials used in China are concrete at present. This kind of safety island needs to build different foundations according to different road surfaces. And rigidity, lack of buffer mechanism, so its impact reaction force is very large, it will cause greater damage to the human body, and also cause damage to the vehicle

Embodiment 1

[0027] Such as figure 1 , 2 As shown in and 8, a cushioning and energy-absorbing safety island anti-collision head can be used at road toll stations. The safety island anti-collision head structure adopts two different forms, the upper layer is hollow, the lower layer is solid, and the thickness of the solid part is the same as The concrete height of the back island body is equal to or slightly larger than that of the back, and the solid part has holes to directly connect with the ground. The structure consists of the anti-collision unit 1 and the fastener 10 . The anti-collision unit 1 is composed of a shell 2 and a filling material body 3 filled in the shell 2. The shell 2 is a solid shell composed of a composite material surface layer 4 cured by glass fiber and vinyl resin; the shell 2 The energy-dissipating material 7 inside is made of polyurethane foam, and the outer side of the polyurethane foam is wrapped with biaxial glass fiber cloth and then laid along multiple lay...

Embodiment 2

[0029] Such as figure 1 , 3 As shown in and 9, a buffer energy-absorbing anti-collision safety island can be used at road toll stations. The safety island anti-collision device adopts a curved surface structure. The curvature of the curved surface matches the front end of the concrete poured safety island. Tunnels connected to concrete safety islands. The structure consists of the anti-collision unit 1 and the fastener 10 . The anti-collision unit 1 is composed of a shell 2 and a filling material body 3 filled in the shell 2. The shell 2 is a solid shell composed of a composite material surface layer 4 cured by glass fiber and vinyl resin; the shell 2 The inner energy-dissipating material 7 is made of polyurethane foam, and the outer side of the polyurethane foam is wrapped with biaxial glass fiber cloth and then laid along multiple layers and directions to form a space lattice structure 6, and then the anti-collision unit 1 is integrally formed by vacuum introduction proces...

Embodiment 3

[0031] Such as figure 1 , 4 As shown in and 10, a cushioning energy-absorbing safety island anti-collision island head can be used at road toll stations. The safety island anti-collision island head is a semi-cylindrical structure with a hole in the semi-cylindrical island head and is directly connected to the ground. The structure is composed of several anti-collision units 1 and fasteners 10 . The anti-collision unit 1 is composed of a shell 2 and a filling material body 3 filled in the shell 2. The shell 2 is a solid shell composed of a composite material surface layer 4 cured by glass fiber and vinyl resin; the shell 2 The inner energy-dissipating material 7 is made of polyurethane foam, and the outer side of the polyurethane foam is wrapped with biaxial glass fiber cloth and then laid along multiple layers and directions to form a space lattice structure 6, and then the anti-collision unit 1 is integrally formed by vacuum introduction process. After the anti-collision u...

Abstract

The invention discloses a buffering energy-absorbing type anti-collision island head for a safety island, comprising an anti-collision unit, connecting elements and a fastening element, wherein the anti-collision island head for the safety island is formed by combining one or more anti-collision units via the connecting elements and fixed on a road surface or the end head position of the safety island via the fastening element, and the anti-collision unit is composed of a housing and a filling material body arranged in the housing; and the housing comprises a composite material surface layer, the filling material body comprises a spatial lattice body and an energy-consuming material, the spatial lattice body is formed by arranging fibre webs, and the energy-consuming material is located in the interior gap of the spatial lattice body and / or between the spatial lattice body and the inner wall of the housing. The invention discloses the buffering energy-absorbing type anti-collision island head for a safety island, which is convenient to popularize, simple and convenient to construct, capable of adequately absorbing collision energy, low in cost, green and environment-friendly.

Description

technical field [0001] The invention relates to a head of a safety island, in particular to an anti-collision head of a safety island which can be used for buffering and absorbing energy and which is set at road tolls, road safety islands and the like. Background technique [0002] With the rapid development of my country's transportation industry, while various high-grade highways are constantly being built, road toll stations are also increasing. Although my country's transportation capacity has been greatly improved, traffic safety accidents at road toll stations have also followed It is not uncommon for vehicles to collide with the head of the safety island or even directly collide with the toll booth. The occurrence of such accidents not only endangers the safety of people's lives and property, but also causes traffic interruption and leads to greater losses. Therefore, it is of great significance to strengthen the construction of anti-collision facilities on the safety...
