AI Technical Summary

Technical Problem

Conventional temporary protective fences face challenges in adapting to different installation forms, such as switching between shoulder and median strip specifications, requiring complex rearrangement and retrofitting of guardrails, which complicates installation and increases the need for skilled labor, especially in time-constrained road improvement projects.

Method used

A temporary protective body design featuring a first and second protective body with symmetrical web and flange portions, utilizing a spacing change member and fixing members to simplify installation and storage, eliminating the need for guardrails with distinct front and back, and allowing for seamless transition between different specifications.

Benefits of technology

This design simplifies the installation process, reduces the need for skilled labor, and enhances efficiency by allowing the temporary protective body to be used in various installation forms without the hassle of differentiating between road shoulder and median strip specifications, thus streamlining the installation and removal process.

Abstract

To provide a temporary protective body that can be applied to conventionally unsuitable installation forms for undulating temporary protective fences.SOLUTION: A temporary protective body 201 includes: a horizontal web part 221 extending in the longitudinal direction; a pair of flange parts 222 and 223 connected to the web part 221 and extending in the height direction H; a first protective body 202 in which an upper recess 224 and a lower recess 225 are defined by the web part 221 and the flange part 223; a second protective body 203 provided above the first protective body 202; and a spacing change member 205 for ascending and descending the second protective body 203 relative to the first protective body 202. At an installation position, a first fastening member 206 is fixed to a web part 231 and protrudes from an upper surface thereof, and a second fastening member 208, which is a fastening member installed in the longitudinal direction L, fixes or releases the second protective body 203 relative to the first protective body 202. At a transport-storage position, a restricting member 213 is provided that maintains a specific distance C, which is the minimum distance between the first protective body 202 and the second protective body 203.SELECTED DRAWING: Figure 23
