The present invention relates to a bridge for railings in which safety ropes are installed so as to prevent the vehicle from falling by embedding a safety rope to improve structural strength of an aluminum member in an overpass or a railing for a bridge, and to prevent the member from falling off due to a collision.

Recently, there have been frequent cases in which a car crashed due to a sliding accident or a collision collision on an overpass or a bridge, causing the vehicle to fall into a fatal accident that injures human life. In order to reinforce this, only foreign prior arts include Japanese laboratories 56-708 (barastar's mounting structure on railings) and Japanese Patent Laid-Open No. 63-44002 (protective measures).

By the way, devises 56-708 devised "Guide part 6 in the interior of the Varastera (5) which is entered between the top rail (2) and the bottom rail (3) connecting the holding (1) and the support (1) ), Through which the long bolt 19 is inserted from the top rail 2 to the guide rail 6 of the barista 5 to the bottom rail 3 ", in particular 63-44002 The invention of the invention is "a structure in which the guide rope 6 is installed in the safe rail 4 which is transverse to the enemy means at the bottom of the top rail 3 which connects the support 2".

Therefore, the above devises have become a reinforcement measure that can bear some of the problems of the conventional vehicle crash without a large increase in installation cost, but in the case of the devise 56-708, a long bolt is added to the conventional railing. As the impact force of the car crashes, the brittle bolt is broken, which is insufficient to prevent the fall accident.In the case of the above-mentioned Japanese Patent Application Laid-Open No. 63-44002, a rope having a high tensile strength is inserted into the saerail 4. More effective than the above, but if the props supporting the sape 4 and the rope are broken, the fall prevention role can not be expected at all, so it was not only effective in weak collisions, but also the sae 4 in the horizontal direction. Installed in the transverse direction, the impact vehicle passes through the vehicle, and the collision vehicle passes therebetween. There was a risk of falling.

Therefore, in order to solve the above problems of the present invention, by connecting the wire rope to the hollow of the upper rail and the support or support of the aluminum railing while still using the shape of the existing bridge rail having the upper rail and the support and support. When viewed from the railing as a whole, the rope-shaped railing is reinforced to be formed so that when the vehicle collides with the railing, the rope forms a net structure to prevent the vehicle from falling and at the same time, it has a strong durability against the external impact of the railing. The structure of embedding the rope is improved, which will be described in detail with reference to the accompanying drawings.

1 is an exemplary view in which the safety rope of the present invention is installed in a conventional aluminum railing for a bridge.

As shown in the drawings, the present invention is installed on the anchor rail 12 fixed on the concrete block 13 " Post 6 and bottom rail connecting the upper rail (2) and the upper rail (2) of the bottom and the lower rail (7) from the lower end of the post bracket (4) In the bridge railing (1) composed of (7) and the like, the post 6 has two penetration holes 6a provided therein so that the penetration holes 6a of the post 6 are installed from the post bracket 4. 2) two long bolts 5 are inserted to the lower rail 7 and the inner side of the box formed by the upper rail 2 and the post bracket 4 penetrates the reinforcing wire rope 8 so that both ends The auxiliary wire rope 10 connected to the bolt 9 and fixed to the nut through the cap hole 3a of the closing cap 3 and connected to the reinforcing wire rope 8 is a rope hole of the post bracket 4. It penetrates through the center of the post 6 through 4a, and has a structure which is screwed under the through hole 7a of the lower rail 7.

Therefore, the present invention constituted as described above has the auxiliary wire rope 10 installed inside the posts 6 in the longitudinal direction with tight spacing while maintaining the shape of the existing bridge railings with the reinforcing wire rope 8 inside the upper rail. Since it is connected, it has a net shape as a whole, so that there is no fear of the vehicle falling out between the horizontal ropes as in the prior art, and at the same time, two long bolts 5 between the post bracket 4 and the post 6 and the lower rail 7 In addition to being inserted into the auxiliary and the ear rope 10 is also included, and the auxiliary wire rope 10 of each post 6 is supported by the reinforcing wire rope (8) built in the upper rail (2) is usually The handrails are firmly supported by the two long bolts 5 inserted in the post 6, and the built-in wire ropes 8 and 10 form a net structure even when the long bolts 5 are damaged due to a collision of a vehicle. M By these strong and it is possible to support the handrail.

The present invention constituted as described above, the railing is installed by two bolts of long bolts (5) and the upper rail (2) is made by overlaying on the post bracket (4), the installation is simple, wire rope (8, 10) ) Is easy to insert, and once installed, the handrail is firmly supported by the strength of the long bolts 5 and the tensile stress of the wire ropes 8 and 10, which not only improves durability, but also impacts on vehicles. The built-in wire ropes (8,10) can minimize the damage to life in case of accident by preventing the escape and shock of the vehicle with the mesh screen, and even after such a collision, the handrail's subsidiary materials are not lost by the rope and can be reused when reinstalling. It is an economical design, and especially the present design is an effective design having a wide range of utility because it can be applied to an overpass made of aluminum to improve strength by rope.
