Germany Maurer (Maurer) telescopic device bridge expansion joints, its force in the beam edge beam and hierarchical (above) after rolling profiled steel welded. Early use of steel box beams, structural steel beams and corrugated box side rubber composition (Figure 5-18), and provides 60mm and 80mm as a unit modulo two series (Table 5-7). More recent bridge expansion joints using Z-shaped side sill beams and king with a bird-shaped rubber band combined structure (Figure 5-19) to 80mm as a unit modulus series of specifications listed in Table 5-8. Bridge expansion joints displacement control system, in addition to have been made by the use of beam oblique angle changes to a scalable solution, while the use of elastic system that is to say, a product of a major shift start control mechanism (Figure 5-20) for can not so perfect gqf-c joints, there will be a number of shortcomings or defects surprising style bridge expansion joints, and the need to increase investment to improve, improve and enhance the style essential gqf-c40 joints, this point to study abroad should cd-40 expansion joints, establish a good corporate image, bridge expansion joints regarded him as a business is the vital lifeline. Bridge expansion joints, seams structure is not exposed to the deck, stretching the gap at the ends of the bridge filled with an elastic material and covered with a waterproof material, and then the bridge deck pavement paving comply viscoelastic material, bridge expansion joints bridge deck pavement and other pavement regardless of the formation of a continuum. Connection to the deformation of asphalt concrete joints and other materials to withstand a telescopic structure, such as our common continuous deck, tst carbon body, the main characteristics of these telescopic device is: can adapt stretching deformation and volume of the upper bridge construction Turn the deformation bridge deck pavement joints will allow the formation of a continuous body to warrant an impact, vibration, adapt better performance while driving. Form multiple waterproof construction, waterproof or. Bridge expansion joints in cold areas, easy to mechanization conservation savings to warrant the destruction of joints. Simple construction, general ease of maintenance and replacement. cd-40 expansion joints | Wulanchabu joints | Hengshui Hao-Hao factory direct pass by Hengshui Rubber Company. Hengshui Hao-Engineering Rubber Co. (www.htgcxj.com) strong, credible, Hebei Hengshui site construction materials industry has accumulated a large number of loyal customers.
