Numéro de modèle: JT56JY Marchés d'exportation: Mondial Matériel: Caoutchouc Marque déposée: JianFeng Spécifications: Comme demandes de dessin Code de HS: 5522233 Certificat: ISO9000 Couleur: Noir Connexion: Paquet de transport de bride: dans des palettes ou des caisses en bois Origine: Hebei, Chine Quel est le joint de dilatation & quest; \ nA: \ nIl est un joint structurel le long de la direction verticale de la partie appropriée sur toute la longueur de la maison pour éviter les fissures ou dommages structurels dus au changement climatique & température de la dilatation thermique & contraction & period & period ; \ n \ n \ n \ nII \ nQ: Quelle est la cause des dommages du joint d'expansion et de la quête TST; \ nA:
| 1.Design is not standardized. |
| 2.Expansion joint device itself has a problem. |
| 3.On the back filling material of the expansion device is not taken seriously and carefully selected that cause a decline in the operational quality of retractable devices and produce different degrees of damage. |
| 4.The construction of expansion joints and construction methods are not standardized. |
| 5.Continuous seam setting is not perfect enough. |
\ n \ n \ n \ nIII \ nQ: Quel est le champ d'application du joint de dilatation et de quête TST; \ nA: Les joints de dilatation TST peuvent être utilisés dans tout le pays et période En raison des caractéristiques d'adhérence à température élevée de TST, au moment de la construction, il peut adhérer fermement à la route existante et rapide et la température ambiante n'est pas collante. ne pas être enlevé & période; \ n \ n \ n \ n \ nIV \ nQ: Quelles sont les caractéristiques de joint de dilatation TST & quest; \ nA: Ce qui suit sont les caractéristiques du joint de dilatation TST:
| 1.TST is a kind of high visco elastic plastic material.It is elastic and plastic at room temperature.After high temperature melting, it can be poured into the gravel,and like asphalt concrete after molding.It can bear the load of the vehicle,and it is elastic. |
| 2.Simple structure.TST crushed stone paved directly at the bridge joints,And the formation of the continuous bridge deck pavement,and bridge deck level seamless.The elastic joints can absorb various aspects of deformation and vibration, smooth running, comfortable, no noise, vibration. |
| 3.Convenient and quick construction.After cooling,there can be open to traffic.When the expansion joint needs to be replaced,there can be half edge construction.The traffic on the busy road is not interrupted. |
| 4.Joint and bridge deck pavement,good sealing and waterproof,And the cost is low and durable. |
\ n \ n \ n \ nV \ nQ: Quelles sont les méthodes d'installation du joint de dilatation et de recherche TST; \ nA: Voici les méthodes d'installation du joint de dilatation TST:
| 1.Clean the notch, so as to achieve the design of width and depth.Clear steel bar 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 according to the center position of the expansion joint.The expansion device is arranged in the notch,The top surface of the expansion device should be 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 device is suspended in the reserved slot,the center line of the TST expansion joint should be aligned with the center line of the reserved gap of the top of the beam. |
| 5.To adjust the straight line segment of the expansion device.And the gap of each longitudinal beam should be uniform. |
| 6.In the telescopic device box or the anchor plate,weld with more than Ф16 to high positioning in the vertical direction and weld a steel bar with Ф16 to wide positioning. |
| 7.After telescopic device being in place and anchorage,welding anchor bar and reserved steel bar to ensure that the extension device is fixed and flat. |
| 8.If the expansion device is installed sectionally, seams must be welded.Welding shall be carried out by professional personnel.And then anchored the joint. |
| 9.According to the size of the joint and reserved slot seam make the template,the template in place should cover tightly,to prevent water flowing into the tank displacement.Expansion joint upper plane plus cover plate,to prevent mortar falling into the rubber sealing belt. After checking whether the correct flatness of the device and midline position and the crevice meet the requirements or not.If its meet the requirements,you can pour concrete and fully vibrating compaction of concrete.Pay particular attention to displacement box and the reserved box can not leave empty. |
| 10.After the expansion joints of concrete reaching 80% of the strength, expansion joints can withstand external loads. |
\ n \ n \ n \ n \ nVI \ nQ: Quel est le principe du joint de dilatation et de quête TST; \ nA: Les soi-disant "joints élastiques" sont une sorte de matériau viscoélastique pour faire les joints, de sorte que les joints ont une certaine déformation élastique pour s'adapter à la déformation de la structure & période; \ n \ n \ n \ n \ nVII \ nQ: Quelles sont les exigences structurelles du joint de dilatation et de recherche TST; \ nA: Les exigences structurelles du joint de dilatation TST sont les suivantes:
| 1.In parallel, perpendicular to the axis of the bridge in two directions, it can freely retractable. |
| 2.Firm and reliable. |
| 3.Vehicle passing should be smooth, no sudden jump and noise. |
| 4.Waterproof and prevent infiltration of debris blocking. |
| 5.It's simple and convenient to installation, inspection, maintenance, removal of dirt. |
