Q:What's the expansion joint?
A:
It is a structural joint along the vertical direction of the proper part along the length of the house to prevent structural cracks or damage that due to climate change (temperature of the thermal expansion and contraction).
II
Q:What are the characteristics of
TST Expansion Joint ?
A:The following are the characteristics of TST expansion joint :
| 1.TST is a kind of high visco elastic plastic material.It is elastic and plastic at room temperature.After high temperature melting, it can be poured into the gravel,and like asphalt concrete after molding.It can bear the load of the vehicle,and it is elastic. |
| 2.Simple structure.TST crushed stone paved directly at the bridge joints,And the formation of the continuous bridge deck pavement,and bridge deck level seamless.The elastic joints can absorb various aspects of deformation and vibration, smooth running, comfortable, no noise, vibration. |
| 3.Convenient and quick construction.After cooling,there can be open to traffic.When the expansion joint needs to be replaced,there can be half edge construction.The traffic on the busy road is not interrupted. |
| 4.Joint and bridge deck pavement,good sealing and waterproof,And the cost is low and durable. |
III
Q:What is the principle of TST expansion joint ?
A:The so-called "elastic joints" is a kind of viscoelastic material to do the joints, so that the joints have a certain elastic deformation to adapt to the deformation of the structure.
IV
Q:What's the scope of application of TST expansion joint ?
A:
TST expansion joints can be used throughout the country.Due to the high temperature adhesion characteristics of TST,at construction time,it can be firmly adhered to the existing road and fast.Room temperature is not sticky,and after cooling will not be taken away .
V
Q:What is the damage cause of TST expansion joint ?
A:
| 1.Design is not standardized. |
| 2.Expansion joint device itself has a problem. |
| 3.On the back filling material of the expansion device is not taken seriously and carefully selected that cause a decline in the operational quality of retractable devices and produce different degrees of damage. |
| 4.The construction of expansion joints and construction methods are not standardized. |
| 5.Continuous seam setting is not perfect enough. |
VI
Q:What are the structural requirements of TST expansion joint ?
A:The following are the structural requirements of TST expansion joint:
| 1.In parallel, perpendicular to the axis of the bridge in two directions, it can freely retractable. |
| 2.Firm and reliable. |
| 3.Vehicle passing should be smooth, no sudden jump and noise. |
| 4.Waterproof and prevent infiltration of debris blocking. |
| 5.It's simple and convenient to installation, inspection, maintenance, removal of dirt. |
