Abstract

PURPOSE:To facilitate the construction work, by stretching tension members spreading and supporting a tent between posts arranged in the diametral direction erected at every appropriate interval so as to surround a construction position of a building body. CONSTITUTION:Upper tension members 6a and lower tension members 6b made of steel wires are radially arranged so as to cross together at the center and a center pole 7 is assembled at the crossed center. The tension members 6a, 66 are tensed by an upper tension ring 8a and a lower tension ring 8b. Next, posts 4 are erected at every appropriate distance to make a circle so as to surround an underground wall 1. The central pole 7 of the tension members 6a, 6b hung between posts 4 after the above procedure is vertically pulled up by the stay rope 12 vertically hung. Next, the tension members 6a, 6b are laid by turns in the peripheral direction of the surrounding positions of the posts 4 around the pole 7, between a pair of posts 4 arranged in the diametral direction. In this way, a light and stable structure can be obtained and the construction can be facilitated.
