Description
Technical Field
The utility model relates to a spacing technical field of bridge especially relates to a landscape arch bridge horizontal stop device.
Background
The basic principle of bridge design is safety, applicability, economy and beauty. At the end of the last century, the economy of China is relatively lagged behind, bridge builders pay more attention to the functionality and the economy of bridges, the safe transportation function is taken as the basic design concept, and the landscape design of the bridges is not paid enough attention to. In recent years, bridge construction in China is rapidly developed in a striking scale and speed, and is in a leading position internationally. With the development of economy, the progress of science and technology and the improvement of life quality, people have not met the requirement that a bridge is simply used as a traffic structure. Bridges are increasingly given deeper connotations by people. The bridge is not only used as a building, but also is a symbol of local culture and history, is an artwork with an appreciation function, is harmonious and unified with the nature of human beings, and is a landmark and a name card of a city, so that the bridge landscape design is more and more valued by builders and users, and the term 'beautiful' is more and more deeply thought by bridge builders.
The arch bridge is a bridge system which is applied most early and widely in the world bridge history and is also recognized as the most beautiful bridge structure. The arch bridge is beautiful in that a beautiful main arch curve breeds strong force, generates a leap dynamic force and a leap feeling, is rigid and flexible, has beautiful rhythm, shows harmony and unity with the environment, and becomes landmark buildings in many cities. In recent years, with the development of economy and the attention of people to the design of bridge landscape, an arched girder assembly system bridge which takes a concrete continuous girder as a main stress structure and takes a steel pipe arch as the landscape design appears. The bridge system integrates the advantages of simple and convenient construction of the continuous beam, mature technology, definite stress, beautiful steel arch ring curve, light structure and harmony and unity with the environment, and is more and more applied to urban landscape engineering.
The main stressed structure of the landscape arch bridge is a continuous beam, although the steel arch ring does not bear the constant live load of the main structure, the steel arch ring is used as a part of the bridge structure and needs to bear the self dead load, temperature load and wind load, and meanwhile, the steel arch ring is required not to generate adverse influence and disturbance on the main beam structure except for ensuring the self stability and safety. However, as the landscape arch bridge steel arch ring has low transverse rigidity, large transverse displacement is easily generated under the action of vehicle load, wind load, ship collision or earthquake force, so that large relative displacement is generated between the arch ring and the main beam, and transverse collision between the main arch ring and the main beam can be possibly caused, thereby damaging the main beam structure. At present, the prior art pays little attention to the problems, and a solution and a scheme are blank, so that a device is urgently needed to be researched to solve the problem that the landscape arch bridge steel arch ring generates large transverse relative displacement with a main beam under the load effect to cause transverse collision.
