Q:Please describe the types of the type steel expansion joint?
A:Type steel expansion joint can be divided into the following types according to the performance and installation methods:
GQF-C type,GQF-Z type,GQF-L type,GQF-F type.In these types,GQF-MZL type steel expansion joint device is made of hot-rolled overall forming profiled bar design of Bridge Expansion Joint device.The GQF-C type,GQF-Z type,GQF-L type,GQF-F type steel expansion joint apply to the bridge joint which expansion volume is less than 80mm.
GQF-MZL type steel expansion device is the type steel expansion joint which is made of edge beam, beam, beam and linkage mechanism.It's suitable the medium and large span bridge which its expansion volume is between 80mm with 1200mm.

Q:What are the matters should be attention to about the type steel expansion joint?
A:The following matters should be attention to:
1.If the position of the embedded steel bars on the beam plate is incorrect or there is no pre embedded reinforcement,you need to use the reinforced fill bar.
2.Clean and link the anchor after cutting.
3.The welding seam of reinforcing steel should be enough and the welding should be firm.
4.The surface elevation of concrete should be correct .
5.If you want the effective telescopic performance,you should ensure the anchor should be firm.
6.The curing time of concrete should be enough.Don't open the traffic because of the lack of maintenance time.

 Q:What matters should to do before the installation of type steel expansion joint?
A:The preparation work before installation of expansion joints must be adequate.Before installing the expansion joint:
1.Construction of the staff must be familiar with the drawings of the bridge and the installation of operating procedures of highway bridge expansion joints.Check the smoothness, the straight and the gap between the joints of the expansion joints.
2.Check mechanical equipment and Small equipment are complete or not.Especially to guarantee quality of construction vehicle passing the bridge must be strengthened and abundant,to ensure the smooth progress of the construction.
3.The materials of canvas, plastic sheeting, tape to prevent the pollution of the road should be prepared adequate.
4.Plastic film maintenance, straw mats and water transport tools should be prepared adequate.

Q:What's the main function of the type steel expansion joint? How to realize the function?
A:
The function of the type steel expansion joint is to to prevent the housing cracks due to climate change.
To realize this function,a gap is reserved at certain distance along the length of the building.The building from the roof, walls, floors and other floors above all the components are disconnected.Because the foundation of the building is affected by the temperature change in the ground, it is not necessary to disconnect.Expansion joint width is generally 2 cm to 3 cm, and there are thermal insulation materials in joint.The distance between the two expansion joints is clearly defined in the specification of the building structure.
