Slip base structure with clip device

A structure for supporting a road support, the structure comprising:

• a base plate fixedly disposed on ground in such a manner as to be spaced apart by a predetermined distance from the surface of ground;
• a slip plate slidably disposed on the top surface of the base plate;
• a coupling body protruded upwardly from the center portion of the top surface of the slip plate in such a manner as to be insertedly coupled to the inner lower end portion of a support body;
• a plurality of clips each having an approximately ‘’ or ‘C’-like shape so as to receive the edges of the base plate and the slip plate thereinto, each of the plurality of clips having a fixing bolt fastened to a female screw passed through the top end portion thereof so as to compressedly support the top surface of the slip plate;
• lower roller-receiving grooves formed spaced apart from each other on the top surface of the base plate along the direction of length of the base plate, each of the lower roller-receiving grooves having an arc-shaped section;
• upper roller-receiving grooves formed spaced apart from each other on the underside surface of the slip plate to correspond with the lower roller-receiving grooves, each of the upper roller-receiving grooves having an arc-shaped section;
• and
• taper rollers each having a taper pin-like shape adapted to be inserted into space portions formed between the lower roller-receiving grooves and the upper roller-receiving grooves by the coupling of the base plate and the slip plate.
