1 is a configuration diagram in the present invention.

As shown in the figure, the present invention is fastened to the anchor bolts 23 embedded in the foundation concrete 22 is built to a predetermined standard along the side of the furnace surface (3) protruding As a rail (1) used for a protective measure consisting of a plurality of posts (2) which are to be formed and a rail (1) which is successively arranged in one or a plurality of stages between the posts (2); The rail 1 is a double of the outer pipe 11 and the inner pipe 12 to be connected to the connecting portion 13 formed in the longitudinal direction at two or more places, and the inner pipe 12 has a lattice shape therein. Reinforcing rib 14 is characterized in that formed in the longitudinal direction.

Figure 2 is another configuration of the present invention, Figure 2a is a state diagram, Figure 2b is a cross-sectional view taken along the line A-A of Figure 2a.

In the above configuration, it is more preferable that the inner pipe 12 and the outer pipe 11 are elliptical or oblong in cross section, and the connecting portions 13 connecting them are formed at two upper and lower portions on the short diameter side.

The present invention made as described above is developed as a state just before assembly in Fig. 3, and is used as a rail 1 for protection measures, and the usual material is strength even when manufactured from a light metal such as aluminum alloy. It can be sufficiently secured, and the fabrication has the same cross-section, so it can be produced by extrusion type, so it is suitable for mass production, and a protective measure is installed using the pipe of the present invention as follows.

First, the foundation concrete 22 is constructed along the side of the furnace surface 3, wherein a plurality of anchor bolts 23 are embedded in a predetermined standard to protrude and cure, and the post plate of the post 2 The hole 2 is penetrated through the bolt hole drilled in 21 to be fastened with the nut 24 to enter the post 2. Of course, at this time, if the protective measures of a special structure can be placed in the post 2 according to the structure, for example, in the conventional design illustrated in FIG. The post 2 is to be directly buried in the base concrete 22, but it is not currently used well due to the difficulty of maintenance and maintenance, and the application to the post 2 installed in such a structure is the same. If the quantity or spacing and the structure of the) fits only the road specification, any structure can be applied to the pipe for rail (1) of the present invention.

After installation of the post (2), the pipe of the present invention, which is a guard rail, is divided into two types, namely, a case of a single stage rail and a non-top rail in two or more stages. The description will be divided into the case of using and other cases.

First, when used as the upper rail, as shown in Figure 3, this is to puncture 18 only the lower surface of the outer pipe 11, which is the lower surface of the rail 1 in accordance with the standard of the post (2), 18) The inner pipe 12 is also cut by a predetermined length in accordance with the standard, and at this time, the connecting portion 13 connecting the inner and outer pipes 11 and 12 is also cut out. Insert the perforated 18 portion of the rail 1 cut from the upper end of the post 2 and fasten the bolt 15 to the post 2 side from the upper or front surface of the rail 1 to secure a solid protective measure. Will be. At this time, when the bolt 15 to be used is fastened on the upper surface of the rail 1, only the upper pipe 11 and the upper end of the post 1 of the rail 1 can be easily fastened with a conventional bolt 15. In this case, it is preferable to use a screw to insert the bolt while using the screw, so that the use of another part, such as a nut, can be avoided. As a result, a method of penetrating the long bolt and fastening the nut from the rear side is adopted. In addition, the rail 1 produced is predetermined Since it is manufactured in length, it must be used continuously, and this can be extended by a required length by a known socket connection method, and the socket connection method here is a sleeve which abuts between the rail (1) and the rail (1) and faces the outer or inner circumferential surface thereof. (Sleeve; 16) pads and refers to the method of fastening with a bolt (15).

When used as a middle rail or a lower rail, a long bolt that penetrates the rail 1 at a predetermined height of the placed post 2 and penetrates the post 2 side and is fastened with a nut (post 2 Round type}, the angles (17) on the left and right sides of the posts (2) and the bolts (15) between the angles (17) and the posts (2) and between the angles (17) and the rails (1), respectively, for stronger support. Fastening and mounting may be used.

Since the pipe of the present invention mounted as described above is a pipe of internal and external dual structure, the support strength is improved than the pipe for the conventional rail (1), which in turn can reduce the size of the pipe, enabling the production of a sophisticated protective measure. In particular, since the inner pipe 12 is reinforced with lattice ribs 14 on its inner surface, the inner pipe 12 may have a support strength comparable to that of a solid pipe. In addition, since the inner and outer pipes 11 and 12 form a hollow portion except for the connecting portion 13, the impact force that may be applied to the vehicle while cushioning the outer pipe 11 to the inner pipe 12 during vehicle collision is cushioned. Since the inner pipe 12 is firmly supported by the reinforced ribs 14, it is possible not only to simultaneously improve the cushioning action and the supporting force, but also to provide the restoring force to the crash vehicle since it is a structure that firmly supports the buffer after a short time. Can be immediately guided to normal driving.

In another configuration of the present invention, the inner pipe 12 and the outer pipe 11 are defined to have an ellipse or an ellipse in cross section, which is intended to have the greatest strength with the least material, and in this case, the ellipse (FIG. 2). It is common sense that the longest side of the merchant pipe should be installed in the direction of the collision of the vehicle to obtain the greatest bearing capacity, and the connection 13 connecting the pipes 11 and 12 should be The upper and lower portions of the diameter side are limited in order to secure a buffer distance to allow the outer pipe 12 to be crushed.

As described above, the present invention is easy to assemble the protection measures, acts as a solid support having a buffering action without additional configuration to faithfully perform the purpose as a protection measures while giving a restoring force to the crash vehicle, easy to mass production economical material It is designed to ensure that it is an effective and useful design.
