あった。(Prior Art) A conventional method of dismantling an outer wall portion of a building will be described. As shown in FIG. 2, after an edge of a wall or the like is cut off, an outer wall portion W falls outward from a position indicated by a chain line with a crane or the like. A wire S hooked on the upper end of the outer wall portion is stretched so that the outer wall portion is pulled inward by its own weight, and then the scaffold P located outside the outer wall portion is disassembled. Met.

った。(Problems to be Solved by the Invention) According to the conventional example, when the outer wall part falls down, external finishing materials such as tiles on the outer surface may be scattered on the scaffold side, and mortar is scattered particularly on the outer wall part of an old building. In addition, there is a risk of forgetting to remove the connecting member with the scaffold and pulling the scaffold together with the wire, and further disassembling the outer wall part, the scaffold will become self-supporting and may collapse due to strong wind. There was a problem with danger during and after dismantling.
この発明の目的は、解体作業の安全性を図ることであ

すことを特徴とするものである。(Means for Solving the Problems) In the disassembling method of the outer wall portion of the present invention, after cutting off the wall and the pillar, first, a net for preventing scattering is attached from the upper end portion of the outer wall portion to the outer surface of the wall portion. A scaffold located outside the outer wall portion is dismantled, and thereafter, the reinforcing bars of the columns are left uncut, and then the outer wall portion is turned down toward the inside of the outer wall portion. .
（作用） 足場の解体を先行させて、足場が外壁部と共に引き倒
されることと、足場材の損傷とを防ぐ。飛散防止用のネ
ットが外壁部の仕上げ材等が飛散することを抑える。(Action) Prior to dismantling of the scaffold, the scaffold is prevented from being pulled down together with the outer wall and damage to the scaffold is prevented. The scattering prevention net suppresses scattering of the finishing material on the outer wall.
（実施例） 以下この発明の一実施例を第１図を参照して説明す
る。(Embodiment) An embodiment of the present invention will be described below with reference to FIG.
まず、第１図（ア）に示すように、外壁部１と壁及び
柱の縁切りをしてから、外壁部の上端部にワイヤ２を掛
け、そして外壁部の上端部から外側面に所定長さの飛散
防止用のネット３を垂らす。First, as shown in FIG. 1 (a), the outer wall 1 is trimmed with the wall and the column, and then the wire 2 is hung on the upper end of the outer wall, and a predetermined length is extended from the upper end of the outer wall to the outer surface. Hang the net 3 to prevent scattering.
この際、クレーン等によって外壁部１が倒れないよう
に、保持用のワイヤ（図示せず。）を張る。At this time, a holding wire (not shown) is stretched to prevent the outer wall 1 from falling down by a crane or the like.
ついで、足場４を解体する。解体する足場４は、第１
図（イ）に示すように上の４段までの足場とし、下２段
の足場4aはそのまま残す。また引き倒すフロアーにより
確実に１段以上上げておく。Then, the scaffold 4 is dismantled. Scaffold 4 to be dismantled is the first
As shown in FIG. 7A, the scaffolds up to the upper four stages are used, and the scaffold 4a at the lower two stages is left as it is. Also, be sure to raise one or more steps depending on the floor to be pulled down.
第１図（ウ）に示すようにワイヤ２を張っておいてワ
イヤを引張らずに外壁部１の自重で内側に倒す。最後
に、柱の鉄筋を切断する。As shown in FIG. 1 (c), the wire 2 is stretched, and the wire is fallen inward by the weight of the outer wall 1 without pulling the wire. Finally, the column rebar is cut.
ワイヤ２掛けと、ネット３張りとは、クレーン等で外
壁部１を保持する前の段階でも、後でもいずれの段階で
行ってもよい。The hanging of the wire 2 and the tensioning of the net 3 may be performed at any stage before or after holding the outer wall portion 1 with a crane or the like.

して危険性の少ない外壁部の解体方法を提供できる。(Effects of the Invention) According to the present invention, the scaffold is disassembled prior to the disassembly of the outer wall, so there is no danger that the scaffold will be collapsed by wind or the like without forgetting to connect the walls and pulling the outer wall together with the scaffold. In the case of dismantling, the outer wall is pulled down while stretching the net, so that the external finishing material can be prevented from scattering or the outer wall mortar finishing scattering. It is possible to provide a method of disassembling the outer wall with a small number.
