A joint device of structures is provided to prevent the stress concentration on an asphalt concrete pavement layer by expansion and contraction caused by changes in temperature and environment of concrete structures and to prevent the breakage of an asphalt concrete pavement layer, to prevent the permeation of impurities and water from the outside, to prevent noise occurrence by minimizing frictional force and to improve ride quality. A joint device of structures includes an elastic member installed to a cut recess formed by cutting out an asphalt concrete pavement layer(20) formed on the top of a concrete structure into the appointed width to have elastic force and to prevent the permeation of water from the outside and provided with many pairs of through holes(112) formed on two longitudinal sides of the elastic member at regular intervals and provided with an end projection to make a head of a bolt(116) suspended and outward inclines formed on two longitudinal sides of the elastic member to keep the upper side of the upper side of the elastic member and the upper part of the asphalt concrete pavement layer at the same height and to prevent gap formation, thereby to prevent the permeation of impurities, a fixed plate(120) provided with fastening holes connected with the through holes and formed to be retreated correspondingly to the end projection of the through hole, a height adjusting member formed on the lower part of the elastic member to adjust the height of the elastic member to be at the same line as the upper side of the elastic member and the upper side of the asphalt concrete pavement layer, a compound layer(140) formed by applying compound on the cut recess of the asphalt concrete pavement layer and the upper side of the height adjusting member to attach the elastic member to the cut recess of the asphalt concrete pavement layer and the upper side of the height adjusting member and to prevent the permeation of water or impurities from the outside, many noise reduction projections(160) formed on the upper side of the elastic member to prevent the upper side of the elastic member from making direct contact with wheels of a motor vehicle to reduce noise caused by a motor vehicle passing through the upper side of the elastic member, a cover body(170) installed to cover the head of the bolt fastened to the through hole of the elastic member, and a water leak prevention device installed to the lower side of a rubber plate fixed to a joint of concrete structures to prevent the permeation of water or impurities. |
