Modell Nr .: Bewegung 120mm Exportmärkte: Globale dringende Bestellung: Ja Transport-Paket: in Paletten oder Holzkisten Herkunft: Hebei, China Zertifikat: ISO9000 Klassifizieren: F-Wm Marke: JianFeng Spezifikation: Als Zeichnung Anfragen HS-Code: 5522233 I \ n Q: Was sind die eigenschaften der kamm typ expansion joint? \ N A: Die folgenden sind die eigenschaften der kamm typ expansion joint:

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 \ n IV \ n Q: Was sind die technischen Anforderungen an die Kompensatoren? \ n A: Im Folgenden sind die technischen Anforderungen der Kompensatoren angegeben:

1.Use neoprene rubber(that is,CR,suitable for temperature in 60 °C ~-25° C)or use the natural rubber(that is,NR,suitable for temperature in 60° C~ -40 °C) .

2. The  quality of steel in expansion joint device requirements in line with the provisions of GB374, GB012.Profiled steel,(that is,16MN or Q345) comply with the provisions of JT/T1591.

\ n \ n \ n \ n \ n \ n V \ n F: Was sind die Leistungsanforderungen der Kammausdehnungs-Gelenkvorrichtung? \ n A:

items	numerical value
Maximum horizontal frictional resistance of stretching or compressing (Kn /m)	≤5
The uniformity of deformation in tension or compression(mm) Total variation of maximum deviation	e≤80±1.5 e>80±2.0
The maximum vertical deviation or distortion of the compression or stretch(mm)	0.3~0.5

\ n \ n \ n \ n \ n \ n \ n \ n Q: Wie wird die Dehnungsfuge in der Brückenkonstruktion angeordnet? \ n A: Im Folgenden ist die Anordnung der Brückenkompensationsfuge dargestellt:

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.
