II
Q:What is the principle of TST expansion joint ? &©|160;&©|160;&©|160;
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.

III
Q:What's the scope of application of TST expansion joint ? &©|160;&©|160;&©|160;
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 .
IV
Q:What are the installation methods&©|160;&©|160;of TST expansion joint ?
A:The following are the installation methods&©|160;&©|160;of TST expansion joint :
1.Clean the notch, so as to achieve the design of width and depth.Clear steel bar&©|160;which interference displacement box buried,and the opening of the reserved hole must be greater than the width of the installation of the expansion joint.
2.Check whether the gap between the various beams of the expansion device meets the requirements of the installation temperature,otherwise,Horizontal jack and jig should be used to adjust to meet the design requirements.Adjusted good,immediately install special fixture.
3.Set the lifting device&©|160;according to the center position of the expansion joint.The&©|160;expansion&©|160;device is arranged in&©|160;the notch,The top surface of the expansion device&©|160;should be&©|160;the same as the deck elevation.At the same time pay attention to the aspect and slope should also be consistent with the deck.
4.After the expansion&©|160;device is suspended in the reserved slot,the center line of the TST expansion joint should be aligned with the ce |
