the structure of fixing support bar

The present invention relates to a support bar of the new structure to be fixed effectively support bar is fixed to the floor to secure the other equipment, etc. orchard fixed structure. The holes in accordance with the rotatably supporting bar fixed structure and fixing method according to the invention, and fixed so that the support bar 10 to move the pieces to secure the lower end of the support bar 10 on the inner bottom surface of the hole (12), ( by casting and curing the concrete (13) in the interior of 12) such that the lower end of the support bar 10 is fixed by the concrete block (13a) making the concrete 13 is cured. Accordingly, the support bar is rigidly supported by the said concrete blocks (13a) of the bottom (10), there is an advantage capable of improving the fixing strength of the support bar (10). In particular, that the support bar 10 is to purchase fixed to the inner bottom surface of the hole 12, the concrete 13 in the working or casting for pouring concrete 13 in hole 12 at the bottom is cured the support bar 10 is fixed not to move. Thus, the concrete 13 is in either the operator until the cure holding the support bar 10 or do not have a separate fixing part 24 to be fixed so that it does not have the support bar 10 is moved by using the material; there are advantages to working in a fixed support bar (10) with a minimum of manpower.
