|
1.Expansion joint plate is the comb shaped anti-skid groove plate.It is a supporting structure which is engaged with each other from the gap between the left and the right of the bridge.Its structural rigidity is large and can withstand large horizontal displacement.Its flexible amount of up to 420mm.
|
|
2.The comb type expansion joint has low building height.It can be installed in the height of the bridge deck pavement and the beam does not need the reserved slot,which greatly facilitate the design and construction.
|
|
3.Its wide range of application.New or old bridge beam can be used,Especially suitable for replacement of large displacement bridge plate rubber expansion device.
|
|
4.When the car is running,there is smooth,comfortable,not jump car,and no noise.
|
|
5.It is convenient to transport and install components.Do not need extra long car transport, also do not use the crane to load and unload.
|
|
6.It has a very low cost.The price is less than the modular large displacement expansion device about 20%.

\ n \ n \ n \ n \ n \ n \ n \ n VI \ n Q: Como organizar o dispositivo de junção de expansão na construção da ponte? \ n A: O seguinte é o layout da junta de expansão da ponte:
|
1. The arrangement of the telescopic device should be based on the overall arrangement of the bridge and the geometry of the bridge.Such as longitudinal slope,cross slope,plan Curvature,bearing arrangement,the direction and measurement of three direction displacement.
|
|
When the longitudinal horizontal displacement of the bridge expansion joint is less than 5mm and the vertical displacement is less than 0.5mm,there is no need to install the expansion device.Flexible and waterproof sealing material can be provided in the joint.
|
|
3.The curved bridge expansion device should be set on the radius of curvature.For the Modular expansion device,the maximum width between two middle or middle beam and side beam of the outer edge of the carriageway is less than 80mm.
|
|
4.The expansion device should not be set at the low point of the concave vertical curve of the bridge.

\ n \ n \ n \ n \ n \ n \ n \ n VIII \ n P: Qual é a questão que deve ser dada sobre o método de instalação da junta de expansão da Highway Bridge? \ nA: Os seguintes assuntos devem ser atenção:
|
1,If you want install the expansion joints after the spread the road ,pave road at first to ensure the surface flat of the road,then slot road to install expansion joints.
|
|
2,When you are installing expansion joints,you should check pre embedded steel bar by the end of next seam.If you find a crack or break and improper position or clearance,you must take remedial measures.
|
|
3,Lance the oil layer of the road by using joint cutter to make joint of bridge and take cleaning.Should pay attention to keep the road cut in good condition and no eating phenomenon.Timely removal of the surface of the concrete tank filler and asphalt concrete and chiseling groove after cutting the.This series of processes is very important,and it will affect the quality of concrete pouring.
|
|
4,In the first spot welding part of the pre embedded steel bars and anchor ring to fix its position temporarily.
