PILE, JOINTING METHOD OF PILES AND REMOVAL METHOD OF UPPER PILE
To provide piles which have simples structures and sufficient resistant strength against shearing, whose manufacturing cost is low, and upper sides are easy to be removed after being installed underground, and a jointing method of piles and a removal method of upper piles.SOLUTION: An upper pile 1 is arranged on the top of a lower pile 3, after the lower end part 37 of a long bolt 33 which is penetrated through the upper pile plate 9 provided on the upper pile and the lower pile plate 23 provided on the lower pile 3 is temporarily fixed on a nut 27 provided on the lower pile plate 23, a shear plate 45 is welded and fixed to the upper surface of the lower pile plate 23. The shear plate 45 is in contact with the vicinity of the lower end of the inner side surface of the flange 5 of the upper pile 1. Soil mortar 59 is placed in a groove excavated on the ground 49, and a pile 39 that has jointed the upper pile 1 and the lower pile 3 is built. After the installation of the pile 39, the soil mortar 59 is excavated and the upper pile plate 9 is exposed, the temporary fixing of the long bolt 33 on the nut 27 is released, the upper pile 1 is separated from the lower pile 3, and the upper pile 1 is lifted to the ground.SELECTED DRAWING: Figure 3
【課題】簡易な構造でせん断に対して十分な耐力を有し、製作費が安価であり、地中に設置した後に上側を容易に撤去できる杭、杭の接合方法および上杭の撤去方法を提供すること。【解決手段】下杭３の上に上杭１を配置し、上杭に設けた上杭プレート９および下杭３に設けた下杭プレート２３に貫通させた長ボルト３３の下端部３７を下杭プレート２３に設けたナット２７に仮固定した後、下杭プレート２３の上面にせん断プレート４５を溶接して固定する。せん断プレート４５は、上杭１のフランジ５の内側面の下端付近に当接する。そして、地盤４９に掘削した溝にソイルモルタル５９を打設し、上杭１と下杭３とを接合した杭３９を建て込む。杭３９の打設後、ソイルモルタル５９を掘削して上杭プレート９を露出させ、ナット２７への長ボルト３３の仮固定を解除して上杭１を下杭３から分離し、上杭１を地上に引き上げる。【選択図】図３
