FINGER-TYPE EXPANSION JOINT DEVICE WITHOUT DRAINAGE SHEET

摘要

The present invention relates to a finger-type expansion joint device without a drainage sheet, wherein an expansion joint structure is constructed to have a structure for preventing rainwater or debris from being discharged between finger plates, such that a drainage sheet may be excluded from the expansion joint device. To this end, the finger-type expansion joint device without a drainage sheet comprises: first and second support members (10, 10) which are respectively installed at both side upper plates (1, 1) after a vertical supporter (12) is upwardly stood at the front end of a base plate (11) of a plate shape and a finger assembly stand (14) is formed at the rear end thereof for assembling finger plates (2, 2); a connecting blocking plate (20) which is installed to connect the first and second support members (10, 10) to each other, and supports the lower portion of the finger plates (2, 2) while blocking the intervals between finger units (2a) so as to prevent water or debris from being discharged through the finger units (2a); and an interval maintenance member (30) which is interposed between the first and second support members (10, 10) and the connecting blocking plate (20) in order to grip the connecting blocking plate (20) such that the same may be positioned at the center. Therefore, the present invention can be conveniently constructed, and does not require maintenance or repair caused by a drainage sheet, thereby reducing economic loss.;COPYRIGHT KIPO 2020
