METHOD OF REMOVING CONCRETE FLOOR SLAB
To provide means capable of carrying out the work of disengaging a main girder from a floor slab more effectively.SOLUTION: A method of removing a concrete floor slab includes the steps of: identifying, using an exploratory device, the position of a joining member C in a plan view which is provided above a main girder A and buried inside a floor slab B; disengaging a part or all of the joining member C with its position identified from the floor slab B; and demolishing and removing the disengaged floor slab B. The disengaging work includes, for example, a method of separating the joining member C vertically by inserting a blade of a cutting device 21 such as a concrete cutter from the plane direction of the food slab B to the upward direction of the floor slab B so as to have a predetermined angle.SELECTED DRAWING: Figure 5
【課題】主桁と床版との縁切り作業をより効率的に実施することが可能な手段を提供する。【解決手段】主桁Ａの上方に設け、かつ床版Ｂの内部に埋設されている接合部材Ｃの平面視上の位置を、探査装置を用いて特定する工程と、位置を特定した接合部材Ｃの一部または全部を床版Ｂとの間で縁切りする工程と、縁切りした床版Ｂを解体および撤去する工程とを有する。縁切り作業は、コンクリートカッターなどの切断装置２１の刃を床版Ｂの平面方向から床版Ｂの上方向に向かって所定角度を有するように差し込むことで、接合部材Ｃを上下方向に分離する方法などがある。【選択図】図５
