The present invention relates to an automatic hinge shaft supporting device for a hinged door and, more specifically, to an automatic hinge shaft supporting device for a hinged door, which is embedded in a floor so that the hinge shaft of the hinged door can be installed and which has a hinge shaft housing and a base frame, wherein the hinge shaft housing has a conveniently adjustable position and can be conveniently fixed to the base frame. According to the present invention, an automatic hinge shaft supporting device for a hinged door comprises: a base frame embedded in a floor so that the automatic hinge shaft of the hinged door can be installed; a hinge shaft housing mounted on the upper side of the base frame, and having a hinge groove to couple the automatic hinge shaft; an axial bolt formed at the side of the hinge shaft housing, and fastened with a nut after penetrating a supporting piece formed on one side of the base frame; and bolts respectively fastened to supporting pieces formed on the left and the right side of the above supporting pieces and having female threaded holes. According to the present invention, when operating the bolts or the nut in order to adjust a gap between a door frame and the door or the orientation position of the door while installing the automatic hinge shaft, which is installed on the lower side of the door, in the hinge groove formed in the hinge shaft housing after embedding the automatic hinge shaft supporting device in the floor of a building, an operator can use a tool for the operation of the bolts or the nut conveniently, can install the door firmly, and can have convenience therefor. In addition, according to the present invention, the position adjustment structure and the fixing structure of the hinge shaft housing of the automatic hinge shaft supporting device are very simple, thereby reducing production costs and improving constructability. |
