In the configuration in which the column is supported by only one leg as in Patent Document 1, it is necessary to resist all the force acting on the column with one leg, so the leg and the installation surface (support base in Patent Document 1) It is necessary to make it a strong rigid joint. And when a horizontal force acts on a support | pillar for rigid joining, a big moment force generate | occur | produces in a fixed part with an installation surface. Therefore, high strength is required for the fixing means (the fixing means with the purlin in Patent Document 1) and the installation surface (the support base in Patent Document 1). In particular, when attaching a fall prevention device such as a retractable lifeline as in Patent Document 1 to the support, it is necessary to increase the installation height of the fall prevention device to some extent in order to ensure the workability of the operator. Prop height is required. For this reason, there is a problem that the moment force increases as much as the height of the column.
Moreover, in the structure supported by a plurality of legs as in Patent Document 2, the force acting on the support can be dispersed by each leg, so that the fixing means and the installation surface can be compared with the structure supported by only one leg. There is an advantage that the strength can be lowered. However, as the number of legs increases, the number of places where fixing means are provided increases, so that workability is poor, and processing for providing fixing means for the number of legs on the installation surface is also necessary. Therefore, although it is good to install semipermanently like the antenna support like patent document 2, it is only temporary for a short period during construction work like the case where a retractable lifeline like patent document 1 is attached to a support | pillar. It is not suitable for installation.

  Accordingly, it is an object of the present invention to provide a column erecting apparatus that does not need to increase the strength of the fixing means and the installation surface and has few fixing points with the installation surface and has good workability.
