Abstract: The utility model discloses a plastic elastomer device for a building or road engineering expansion joint, which comprises a cast-in-situ concrete layer and an asphalt concrete pavement layer arranged at the upper end of the cast-in-situ concrete layer; an expansion joint is arranged in the center of the cast-in-situ concrete layer; a sponge body or a foam body is filled inside the expansion joint; a notch is arranged in the center of the asphalt concrete pavement layer and is filled with a flexible elastomer and gravel; a cover plate is arranged in the notch; lower expansion bolts are eudipleurally arranged at the upper part of the cast-in-situ concrete layer; side expansion bolts are eudipleurally arranged on the inner side of the asphalt concrete pavement layer; and reinforcing steel bars are arranged between the end parts of the side expansion boles and the end parts of the lower expansion bolts. The plastic elastomer device has a simple structure and a reasonable design and is convenient and quick for construction; and the requirement for expansion joint performance can be better met, the installation of a special expansion member is avoided and the problem that the service life of the other expansion devices is short under small flexibility can be effectively solved. Meanwhile, the plastic elastomer device has the characteristics of bearing performance for vehicle load, favorable elasticity and attractiveness and smoothness in surface. | |
