expansion joints to prevent leaking water

摘要

The present invention relates to a expansion joint for preventing leakage, and filling the filling material in the central separation gap of the expansion joint, having a drainage passage in the lower side, and the end closure having an end closure having a drain hole connected to the drain pipe at the end side of the drainage passage, By constructing the drain, it is for preventing corrosion, extending the life and stability of the bridge through leakage prevention.;The present invention is provided with a shoe 20 on the lower piers 10, the upper slab layer 40, the asphalt pavement surface layer 60, which reinforces the PC beam 30, the reinforcement 50 from the bottom thereon is After mounting the bridge top plate having a structure that is formed integrally formed in sequence, in the expansion joint 100 installed in the gap between the top plate and the top plate, it has an L-shaped longitudinal section, and forms a buried fixed anchor portion 114 on one side In addition, the other end portion 111 and the inclined groove portion 112 is provided with a symmetrical expansion joint body portion 110 is formed in the lower portion of the cross-section is formed with an insertion groove portion 113 having a circular round inner end portion, Filler 120 is provided in the space between the expansion joint body portion 110, the insertion blade piece 131b is inserted into the insertion groove portion 113 of the expansion joint body portion 110 on both sides of the arc portion (131a). A drain passage 131 having a cutting portion 131c formed on the lower surface of the end portion, and cutting of the drain passage 131. A drain 134 formed with a cutting portion 132c assembled with the 131c and an arc portion 132a and the insertion blade piece 132b of the same shape, and having female threads formed at the upper strainer 133 and the lower short tube end. End portion 132 having an end portion 132, and the end portion 132 consisting of an end plate 138 formed with a fixing hole 138a to be coupled and fixed by a fixing bolt 139 on the outside of the end portion 132. With a), by integrating the expansion joint body portion 110 below the filler 120, to provide expansion joints for the leakage of the maximum effect.;Through such a configuration, the leakage prevention effect is maximized, thereby preventing corrosion, extending the life and increasing the stability of the bridge, and having a replaceable filter mesh at the top of the drain hole to prevent the drain pipe from being blocked and the road surface. It minimizes bridge damage caused by foreign substances entering the phase and prevents rainwater or foreign matter from penetrating into the pier by rain or foreign matter penetrating into the outer space by the end plate.;In addition, it is possible to smoothly drain on the bridge to prevent large accidents due to the residual rainwater, etc., and the expansion joint body part and the drainage part is integrally assembled and firmly coupled to increase the workability in the bridge installation.
