NO. De modèle: type Z, F, E Certificat: ISO9000 Marchés d'exportation: Paquet global de transport: dans des palettes ou des caisses en bois Origine: Hebei, Chine Fonction: Type d'absorption de choc de pont: "F" et "Z" Marque: JianFeng Demandes de dessin Code SH: 5522233 Q: Pouvez-vous me donner une description du joint de dilatation de pont modulaire? \ N A: Le joint de dilatation de pont modulaire peut être divisé selon les types de performance et d'installation suivants:

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.

\ n \ n \ n \ n \ n \ n \ n \ n II \ n Q: Quelle est la fonction principale du joint de dilatation de pont modulaire? Comment réaliser la fonction? \ N A:

The function of modular bridge 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.

\ n \ n \ n \ n \ n \ n \ n \ n \ n III \ n Q: Quelles sont les exigences structurelles du joint de dilatation de pont modulaire? \ n A:

1.In the two directions of being parallel and being perpendicular to the axis of the bridge are free to flex.

2.Firm and reliable.

3.There is smooth and there has no sudden jump or noise when the vehicle is passing by.

4.Waterproof and prevent infiltration of debris blocking.

5.It's simple and convenient to Installation, inspection, maintenance and removal of dirt.

\ n \ n \ n \ n \ n \ n \ n \ n \ n \ n \ n \ nQ: Quelles sont les questions auxquelles le joint de dilatation de pont modulaire devrait porter attention? \ n R: Les points suivants doivent être pris en compte:

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.

\ n \ n \ n \ n V \ n Q: Quelles sont les procédures de construction du joint de dilatation de pont modulaire? \ n A:

1.Dig slot and clean slot.

2.Punch Positioning hole.

3.Lay anti crack reinforcement net.

4.Water bottom.

5.Install steel plate.

6.Water concrete on both sides of the transition section.

7.Maintenance and maintenance.

\ n \ n \ n \ n \ n \ n Q \: Q: Que doit-on faire avant l'installation du joint de dilatation de pont modulaire? \ n A: Les travaux de préparation avant l'installation des joints de dilatation doivent être adéquats. l'installation du joint de dilatation:

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.
