Description
Technical Field
The utility model belongs to the technical field of the bridge beam supports, especially, relate to a tensile support slides from restoring to throne one-way.
Background
In recent years, the highway transportation causes cost effects such as environmental pollution, energy consumption, transportation cost, transportation safety and the like, and brings great challenges to the harmonious development of human and nature. The strategic mode of the transportation in China is 'preferentially developing railways and promoting the coordinated development of railways and highways' in the future, and therefore the importance and universality of the transportation of high-speed railways are more practical and novel. With the increasing development of high-speed railways, the application of the support in bridges is indispensable, and the support is more widely applied to railway joints among oceans, lakes and mountainous areas.
In the case of bridges, the support is generally disposed at a supporting portion of a bridge span structure, a bridge pier and a bridge abutment, plays a role of a transmission force, and is an important structural component for connecting an upper structure and a lower structure of the bridge. The counterforce, the deformation displacement and the corner of the upper bridge structure are reliably transmitted to the lower bridge structure through the support, so that the actual stress condition of the structure is ensured to be more consistent with a designed theoretical model, and the safety of the bridge structure is ensured. Along with the diversity of bridge and building structure form, also increased the variety of support function. The existing simple support supports the upper structure by arranging a cushion layer between the beam bottom and the pier top surface, is only suitable for a small-span bridge, but is rarely adopted at present due to poor free flexibility. The steel support is used for completing the displacement and rotation of the support by rolling, shaking and sliding of steel parts, has strong bearing capacity, but is also properly selected due to the complex structure and large steel consumption of the cast steel support. The plate type rubber support generates compression deformation under the action of live load of the train, and compared with the basin type rubber support, the plate type rubber support has the advantages that the manufacturing cost is slightly low, and the plate type rubber support has the functions of vibration reduction and noise reduction; the basin-type rubber support is a rubber support further improved on the basis of a plate-type rubber support, and has the characteristics of strong bearing capacity, large horizontal displacement, small friction coefficient, large corner, less steel consumption and the like; however, because the rubber support is limited in mechanical performance, the comprehensive rigidity of the bridge substructure is low due to the low longitudinal shear rigidity of the rubber, and the additional stress of the steel rail is high under the action of braking force, so that the rubber support is generally only adopted under a simply supported beam, and a cautious attitude should be kept for the use in the continuous beam of the rail transit viaduct. The spherical bearing is further developed on the basis of the basin-type rubber bearing, is suitable for multidirectional rotation of bridges, has large allowable horizontal displacement and excellent performance, and is widely adopted in domestic and foreign urban overpasses and highway bridges at present.
The support of the beam bridge is generally divided into a fixed support and a movable support, wherein the fixed support is used for fixing the position of the main beam on the abutment and transmitting vertical pressure, and ensuring that the main beam can rotate freely at the support when being deflected, namely, the fixed support allows the beam section to rotate freely but not move, and the movable support is used for transmitting vertical pressure and ensuring that the main beam can rotate freely at the support and can move horizontally, namely, the movable support allows the beam to rotate and move when being deflected and stretched. In addition, in a continuous beam bridge, a cantilever beam bridge, a skew bridge, etc., tension is generated at some pivot points due to the load, and at this time, the support must have a tensile function and can bear corresponding rotation and horizontal displacement. Aiming at the movable support, when the movable support is acted by a transverse bearing force, the movable support can generate horizontal displacement and rotation, how to enable the sliding support to be capable of resetting and playing a role again without external force, how to develop a multifunctional one-way sliding support with self-resetting and tensile effect, and how to reduce the replacement and maintenance cost of the support, which is just the problem that bridge science and technology workers need to face. Therefore, it is very important to develop a tensile support with self-resetting unidirectional sliding.
