1. Description of Bridge elastomeric expansion joints
Expansion joints [joint expansion] refers to the gap between the structure and the structure which is affected by the expansion and contraction of the material.
Expansion joints, also known as the temperature crack is one of common noun for construction engineering. Its main function is to prevent housing due to climate change, and cracks. The approach for building the length direction along every certain distance slot reservation, buildings will be from the roof, wall, floors above ground members are disconnected, building foundation for its buried in the ground by temperature changes little influence, need not
disconnect. Telescopic seam width is generally 2 cm to 3 cm, filled the joint insulation material, the spacing of the two expansion joints in the code of building structure is clearly defined.
| 1.1 If building plane size is too long, because of heat expansion and cold contraction may lead to the appearance of temperature stress in the structure, in structure with a certain length position located in the raphe and the building is divided into several parts, the seam is temperature joint. To different structures, expansion joints between the different distance, China's current standard < code for design of concrete structures >GB50010-2010 this has special provisions. |
1.2 Bridge application
In order to meet the requirements of bridge deformation, usually between the ends of two beams, beam end and the abutment, or between the bridge, the hinge position set expansion joints. |
2. Features of Bridge elastomeric expansion joints
1.It makes bridge smooth and seamless, and it's good for preserving, cleaning and moving snow.
2.The structure is simple, no need to have special stretch frame and anchoring steel bar. Construction is convenient and fast.
3.It could absorb all kinds of deformations and shaking. And its damping property is high and it's good for bridge shock absorption.
4.Best sealing and waterproof property and anti-acid-base and corrosion.
5.Low cost of construction, durable and remarkable economic benefit and social benefit.
3.Applications of bridge elastomeric expansion joints
Hengshui Jianfeng Engineering Rubber co., LTD. is a specialist in the field of Expansion Joint Supply-and-Installation, Rehabilitation and Repair allowing us to cater for a variety of applications including Bridges, Car Parks, Elevated Structures, Footbridges, Stadium, etc.
4. Requirements of bridge elastomeric expansion joints
| Items | Rubber |
| Plate-type | Combined type |
1. Max horizontal frictional resistance
of expansion and compression(KN/m) | <18 | ≤8 |
2. Max vertical deviation or deformation
of expansion and compression | -3-3 | -2-2 |
5.Bridge elastomeric expansion joints are designed to accept both horizontal
and vertical loads due to traffic in accordance with the road engineering
technical standards JTJ-88(1995).
