PURPOSE:To facilitate erecting panels by adjusting the projection length of a threaded shaft by a method in which a cylinder with an inside thread is buried in the foundation by exposing its opening on the top of the foundation. CONSTITUTION:A cylinder 2 with an inside thread 7 is buried in the foundation by exposing its opening 3 on the top of the foundation, and a threaded shaft 6 is screwed with the cylinder 2. The threaded shaft 6 is pulled up and thrust through a hole provided in the bottom piece of a base metal 13 of an L-shaped cross section, and a nut is screwed with the shaft 6 to fix it to the base metal 13. A panel P is fitted into the crown 19 on the downside of a beam 17, and the groove 15 of the panel P is attached to the erected piece of the base metal 13 to attach the panel P. By burying a cyliner 2 with an inside thread 7 in the foundation, the projection length of the threaded shaft 6 can be adjusted and the erection work of the panel P can be performed easier. |
