<p>PROBLEM TO BE SOLVED: To efficiently hold structural members such as frame materials supported by timbering and to accurately hold an interval between adjacent structural members.SOLUTION: A timbering device 20 includes fourth support plates 35, 36 which are provided on a sleeper 30 supported by a pipe support 21, and notches 37, 38 are formed in the fourth support plates 35, 36 respectively. Here, when an arch member 12 is fitted to the notches 37, 38 of the fourth support plates 35, 36, the arch member 12 can be supported without shifting it. Thereby, the arch member 12 can be efficiently held. Moreover, since a central part of the sleeper 30 is positioned only by positioning both ends of the sleeper 30, coordinate alignment of the fourth support plates 35, 36 becomes easy. Consequently, an interval between adjacent structural members can be accurately held.</p> |
