Abstract
The present invention relates to an expansion joint device that fills a changing expansion space by connecting a space part by expansion and contraction due to temperature change to a top plate connection portion of a bridge, for example, in construction technology. The present invention relates to a new expansion joint of a bridge deck with a structure that is superior in performance and function, is easy to maintain, and reduces noise when passing through a vehicle. The main structure of this invention is the plate 3 provided in the edge part of an upper plate, the lower plate 11 provided in the upper part of the plate 3, and the link piece 10 of stepped shape provided inclined on the lower plate 11. ), A fixing pin 20 pivotally fixing one end of the link piece 10, a press plate 13 coupled to the other end of the link piece 10, and a inside of the press plate 13. It characterized in that it comprises an elastic body 15 for reducing the noise between the link piece 10 and the pressing plate 13, and a fixing piece 17 for fixing the pressing plate 13 to the plate 3, the lower plate 11 Stepped to form a step-shaped link piece 10 is characterized in that it is pivotally fixed by the pin 12, one end of the link piece 10 is stepped with a stepped lower end ( 35 is formed so that the lower plate 11 is accommodated in the stepped portion 35, and the pressure spring 30 is installed on the side of the lower plate 11. , Always characterized by configured to configure during expansion and contraction of the top plate, a lower plate 11, the pin 12 is pushed to the right and left so as to turn the mill by pressing the lower plate (11).
Description
