TEMPORARY GUARD WALL

To provide a temporary guard wall that can be installed and uninstalled in a short time and can secure a work space.SOLUTION: A temporary guard wall 1 installed along a track R1 and separating the track R1 and a construction area CA, comprises: a plurality of posts 2; a plurality of cross beams 3 spanning the posts 2; a panel material 4 attached to the cross beams 3; and bracing posts 5 that are inclined and connected to the posts 2. The posts 2 join closing surfaces of a pair of U-shaped members having U-shaped cross sections to form saw blades at the ends of opening grooves, and the bracing posts 5 have U-shaped members having U-shaped cross sections in which saw blades are formed at the ends of the opening grooves. The bracing posts 5 are installed on the track R1 side of the posts 2. The posts 2 and the bracing posts 5 are configured to be connectable to any position of the saw blades via connection members that mesh with the saw blades.SELECTED DRAWING: Figure 2 【課題】短時間で設置や取外しが可能で作業空間を確保することのできる仮設防護壁を提供する。【解決手段】軌道Ｒ１に沿って設置され、軌道Ｒ１と工事区域ＣＡとを区画する仮設防護壁１において、複数の支柱２と、これらの支柱２に架け渡された複数の横梁３と、これらの横梁３に取り付けられたパネル材４と、支柱２に傾斜して連結される控え柱５と、を具備し、支柱２は、一対の断面コの字状のコの字部材の閉塞面同士を接合し、開口溝の端部に鋸刃を形成するとともに、控え柱５は、開口溝の端部に鋸刃が形成された断面コの字状のコの字部材を有し、控え柱５を支柱２より軌道Ｒ１側に設け、支柱２と控え柱５を、前記鋸刃と噛合する接続部材を介して前記鋸刃の任意の位置に連結可能に構成する。【選択図】図２
