The plate rubber expansion joint is made of steel plate as the skeleton, and the bolts are assembled in sections, each piece is 1m (can also be made into other sizes), and the joint is fitted by the groove tenon. The internal stiffening steel plate allows this type of expansion joint to withstand the loads of various vehicles with a certain vertical stiffness. Due to the incompressibility of rubber, a specially shaped expansion groove on the rubber sheet prevents upward bulge when the expansion joint is compressed.
Characteristics of plate rubber expansion joints.
1. The plate rubber expansion joint has good waterproofness, because the adhesive is poured in the bolt hole on the bottom surface of the expansion joint and at the assembly place of each meter.
2. The wear resistance and aging resistance of plate rubber expansion joints are very good, and they can withstand the repeated load of vehicles and have a long service life.
3. Plate expansion joints are also relatively cheap, and they are extremely convenient to install and replace.
Assemble in sections, bolt the parts, so that the driving will be safe, there will be no accidents, and it will be balanced and comfortable.
Conventional models: 30-type plate rubber expansion joint, 45-type plate rubber expansion joint, 50-type plate rubber expansion joint, 60-type plate rubber expansion joint, etc.
It is precisely because the plate rubber expansion joints are more favorable and more convenient to install than the section steel expansion joints, and have become the first choice for road and bridge construction in developing countries. The company has exported 2,000 pieces of plate rubber expansion joints to Nigeria to support the construction of roads and bridges in the country, and has been well received.
