SURFACE PREPARATION DEVICE OF TEMPORARY FRAME ASSEMBLING SCAFFOLD BOARD IN CONSTRUCTION WORK

摘要

PROBLEM TO BE SOLVED: To develop and provide a surface preparation device of a scaffold board which is simple and low in a price by not installing the other complicated constitution, in the surface preparation device having means for surface-preparing only a surface side of the scaffold board.;SOLUTION: In a surface preparation device (1) of a temporary frame assembling scaffold board in construction work which sequentially transports the scaffold boards (X) by a feed mechanism (Y), a liftable surface preparation machine (20) is arranged in the middle of the feed mechanism, approach sensors (30) for detecting a hook part (Xa) of the transported scaffold board (X) are arranged at an upper part and a lower part of the feed mechanism (Y), the scaffold board (X) is fed while being offset downwardly, a surface side of the scaffold board (X) is surface-prepared when ascended by hoisting the surface preparation machine (20) in an up-and-down direction in the middle, and the hook part (Xa) of the scaffold board (X) is made to pass when descended.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2018,JPO&INPIT
