Finger-type expansion joint device without drainage sheet

A finger type expansion joint not having a drainage sheet, comprising:

• first and second support members (10, 10′) in each of which a vertical support (12) is upward erect at one end of a sheet-shaped base plate (11) and a finger assembly mount (14) is disposed at the other end of the base plate (11) so that finger plates (2, 2′) are assembled by bolts (B) and are installed in upper plates (1, 1′) on both sides of a bridge which face an isolated space, respectively;
• a connection block plate (20) which is installed to interconnect the first and second support members (10, 10′) to each other, support bottoms of the finger plates (2, 2′), and block water or an alien substance from being discharged between finger parts (2a) by providing blocking between the finger parts (2a);
• a gap maintenance member (30) which is interposed between the first and second support members (10, 10′) and the connection block plate (20), wherein the gap maintenance member (30) places a location of the connection block plate (20) in a middle of the first and second support members (10, 10′) by an elastic action;
• and
• a tube fitting (70) for drainage installed below the vertical support (12),
• wherein the tube fitting (70) includes a drainage pipe (72) having one end connected to the tube fitting (70), the other end extended to an outside of each of the first and second support members (10, 10′) to discharge, to an outside, the alien substance stagnated in each of the first and second support members (10, 10′).
