18232937111 buffer chain bridge anti falling chain
During the earthquake, the special high-strength rubber buffer chain between the rings and buckles is compressed, which gradually increases the chain effect force and avoids the impact of the earthquake force to weaken the chain strength. The planning strength of buffer chain link and strong chain link is divided into two levels, so that the weak link of the whole chain is always set in the part of buffer chain link, so as to ensure that the planning strength of buffer chain bridge anti falling chain is within the planned regional scale. The buffer link and the strong link are connected by the strong shackle, which is convenient for chain assembly and replacement. The embedded anchor bolt and embedded plate are embedded in the beam body or pier and abutment, and the tensile seat is connected with the embedded anchor bolt through the connecting nut of the anti falling chain of the buffer chain bridge, which can not only ensure the accuracy requirements of the device accurately, but also facilitate the construction of the bridge and pier and the device after the completion of the construction. The buffer chain link, strong chain link and strong shackle shall be the buffer chain bridge anti falling chain, the adjustment shackle at the buffer chain end or the adjustment shackle at the strong chain end shall be connected with the tensile seat.
The anti falling beam chain bar buffer chain bridge anti falling chain the anti falling beam bridge structure, the pier body anchor plate is arranged on the pier body anchor seat, the outer body anchor ring is arranged on the pier body anchor plate, the beam body anchor plate is arranged on the beam body anchor seat, and the beam body anchor ring is arranged on the beam body anchor plate. The utility model has the following advantages: a cable is passed through the pier body anchor Rongxian anti falling beam chain bar manufacturer ring and the beam body anchor ring, the cable is symmetrically passed through the pier body anchor seat and the beam body anchor seat, and the two ends of the anti falling chain cable are fixed together. In this way, the tension generated by the displacement between the two beams during the earthquake is transmitted to the cable through the beam anchor seat, and then to the anchor hemp of the pier through the cable, In the initial stage, the cable is gradually tensioned along with the gradual stress of each point of force, and the anti falling chain of the buffer chain bridge is gradually tensioned. Because it is a steel wire rope that passes between the beam anchor ring and the pier anchor ring, the length of the cable between the beam anchor ring and the pier anchor ring is continuously adjusted until each anchor ring starts to be evenly stressed in the process of tension In the process of anti falling chain of buffer chain bridge, the tension caused by the displacement between two beams caused by earthquake is a buffer process. At the same time, the stress of the cable is relatively dispersed, extending the service life of the cable. The utility model not only has the reliable longitudinal anti falling beam function, but also has the firm transverse anti falling beam performance. The vertical and horizontal are effectively matched, the anti falling chain structure of the buffered chain bridge is multiplied, the function is perfect, and the fatigue is achieved.
