SCAFFOLD CONSTRUCTION METHOD
To provide a scaffold construction method for constructing a work scaffold around a bridge pier of a bridge installed on a water area, without using a barge.SOLUTION: A scaffold construction method includes: on a bridge, suspending and forming a carry-in passage 8 from a land on one side of the bridge to a target bridge pier 1; and, on the bridge, suspending and forming a work scaffold 4 so as to make the work scaffold be installed continuously with the carry-in passage 8. In forming the work scaffold 4 is used a foldable and disassemblable scaffold forming part 2 comprising a plurality of beam members 11, a beam connection member 12 to which the beam members 11 are connected in a horizontally rotatable and detachable manner, and a connection holding shaft 13 to be a connection rotation shaft between a beam member 11 and the beam connection member 12, the scaffold forming part being assembled by making a shaft insertion hole 14 of the beam member 11 and a shaft insertion hole 15 of the beam connection member 12 communicate with each other before inserting and disposing the connection holding shaft 13 into the shaft insertion holes.SELECTED DRAWING: Figure 1
【課題】台船を用いることなく、水域上に架設される橋梁の橋脚の周囲に作業足場を構築する足場構築工法を提供することを目的とする。【解決手段】橋梁の一側の陸地から目的の橋脚１に向かう搬入路８を橋梁に吊設形成し、この搬入路８に連設させて作業足場４を橋梁に吊設形成すると共に、この作業足場４を形成する際に、複数の梁部材11と、この梁部材11が水平回動自在且つ着脱自在に連結される梁連結部材12と、梁部材11と梁連結部材12との連結回動軸となる連結保持軸13を備え、梁部材11の軸挿通孔14と、梁連結部材12の軸挿通孔15とを連通状態にし、この軸挿通連通孔に連結保持軸13を挿入配設して組み立てる折り畳み分解自在な足場形成部２を用いる。【選択図】図１
