The present invention relates to a repair method to replace expansion joints for bridges.
The invention plant on an upper surface of the fixed-angle (500) After taking to kick the next cutting rail (R) was cut on the lower part of the rail-type stretching the rail (R) projecting so as to leave only the fixing angle 500 for replacement of joints previously prepared, and one bottom surface, the said rail (R) cutting the projections 501 511 is a receiving groove 113, 123 to be received is formed in the other upper surface of the opened engaging upstream groove 112 (122) by at is formed, the base plate 110, 120, both fixed piece (240 of the waterproof sheet 200 to the facing each other form which is located at the separation space 100 sikidoe respectively fixed place by close contact with the fixing angle 500 ) locking projection 242 formed on the bottom of 250, 252 is the base plate 110 (by fixed in a state such that each engaging the locking groove 112, 122, 120) and continuous to the upper surface a joint plate (S1) (S2) of the pair is replaced when so coupled.
The invention has the advantage of effectively made the contraction and relaxation of course have been separated from the space filled with a waterproof sheet is foreign material infiltration block are possible through the elastic restoring force of the waterproof sheet is formed for expansion joints in bridges.
