ASPHALT JOINT SINKING PREVENTION APPARATUS OF CONSTRUCTION

摘要

The present invention relates to an asphalt subsidence prevention facility for a construction complex. The present invention comprises: a pair of side frames symmetrically installed in both sides of a road, and including a sawlike or moir-shaped frame fixing part formed in the upper part of the inner surface in a vertical direction to be fixed with concrete, a frame installation groove formed at a distance in the lower part of the frame fixing part, and a fixing support groove formed on the floor in a longitudinal direction; a frame fixer consecutively installed on the floor, and including a frame fixing protrusion formed in the upper part to be combined with the fixing support groove of the side frames; a fixing plate placed between the side frames while placed in the lower part of the frame fixing part, and including a ground fixing part and a discharge passage, formed in a trapezoid shape at regular interval; an upper buffer part consecutively installed in the lower part of the fixing plate in a horizontal direction, and relieving a shock; a middle buffer part installed in the lower part of the upper buffer part, and including a horizontal plate installed between the side frames, and a plate fixing unit formed on both sides of the horizontal plate and including a plate fixing groove to have a side installed in a side frame support groove and have the other side supporting the horizontal plate; and a lower buffer part formed by combining flat springs consecutively installed in the lower part of the middle buffer part. According to the present invention, the present invention is capable of reducing costs for maintenance as well as preventing asphalt subsidence while at the same time preventing accidents by installing the asphalt subsidence prevention facility in the lower part of soft ground or in a vehicle passage section of a building complex.
