Description
Technical field
The utility model relates to a kind of mobile bracing frame, especially relates to a kind of mobile bracing frame that is used for bridge construction process.
Background technology
Human at protohistory age, cross over water channel and valley, be the trees that utilize nature to fall down, the stone beam or the stone arch that form naturally, the stone that the mountain stream is outstanding, the Chinese wistaria of paddy bank growth etc.The mankind on purpose lumber to bridge or enrockment, frame stone are when bridge starts from, and have been difficult to textual criticism.According to the historical data record, beam bridge and pontoon bridge have been had in the Zhou Dynasty (B.C. 11st century～preceding 256 years) in China, and as B.C. about 1134, the Western Zhou Dynasty, the water frame had pontoon bridge in Weihe.Ancient babylonia is at the B.C. wooden bridge of building multispan in 1800, and bridge reaches 183 meters.Ancient Roman built the wooden bridge of crossing over the Tiber at B.C. 621 years, erected the pontoon bridge of crossing over these other straits of haler at B.C. 481 years.Mesopotamia area was built up when B.C. 4th century and was chosen stone arch bridge (soffit is a step) ancient times.Ancient times, bridge was before the 17th century, generally was to build with wood, stone material, and was divided into stone bridge and wooden bridge to bridge by the bridge construction material.
18th century iron production and casting, for bridge provides new construction material.But the cast iron shock resistance is poor, and tensile property is also low, and easy fracture is not good bridging material.After the fifties in 19th century, along with the development of acid converter steel-making and open hearth steel-smelting technology, steel become important bridging material.The tensile strength of steel is big, and shock resistance is good, the seventies in 19th century especially occurs steel plate and the rolling section steel of rectangle, in factory, assembles the condition of having created for the parts of bridge, and it is increasingly extensive that steel are used.18 beginnings of the century, invented the cement that forms with lime, clay, bloodstone mixed calcining.The fifties in 19th century, begin to be employed in and place reinforcing bar in the concrete to remedy the shortcoming of cement tensile property difference.After this, built up reinforced concrete bridge the seventies in 19th century.
Modern age, bridge construction promoted the rise and the development of bridge scientific theory.1857 by Sheng Wonan on the basis of theory, statics and mechanics of materials research of forefathers to arch, proposed more complete beam theory and reversed theory.This, theory of continuous beam and semi girder was also set up in period.Bridge truss is analyzed (like the analytical method of Warren girder and Howe truss) and also is resolved.The seventies in 19th century, structural mechanics obtained very big development, can analyze the stress that each member of bridge takes place under load action after people's such as German K. Coleman, British W.J.M. Rankine and J.C. Maxwell effort.The development that these are theoretical has promoted the development of truss, continuous beam and semi girder.In 19 end of the centurys, elastic arch theory is more perfect, has promoted the arch bridge development.The twenties in 20th century soil mechanics rise, promoted the theoretical research of bridge foundation.
In the work progress of bridge, there is certain height the bottom of bridge apart from ground usually, and workman's height can't reach, and not only cost is high to use large-scale equipment, and volume is big, moves inconvenience, incurs loss through delay the duration.
