Description
Technical field
The utility model relates to a kind of linkage, especially relates to a kind of linkage 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.
Bridge needs to adopt different steel pipes to connect when building, because the One's name is legion of steel pipe can produce infall sometimes, needs to adopt device that cross one another steel pipe is connected, and increases stability.
The utility model content
The purpose of the utility model is to overcome the shortcoming and defect of above-mentioned prior art, and a kind of linkage that is used for bridge construction process is provided, this linkage simple in structure; Utilize through hole that steel pipe is connected, especially, increase stability of structure at the steel pipe of the intersection of different directions; Can repeatedly utilize; And convenient disassembly, save the set-up time, increase work efficiency.
The purpose of the utility model realizes through following technical proposals: be used for the linkage of bridge construction process, comprise that the center is provided with the sleeve pipe of tapped through hole, said sleeve pipe is provided with mount pad, and said mount pad is provided with through hole.
The center line of said through hole is vertical with the center line of tapped through hole.
Said sleeve pipe is provided with holder in the side away from mount pad, and said holder is provided with groove.
Said holder is provided with through hole, and said through hole penetrates the inside of groove, and the center line of said through hole is parallel with the center line of through hole.
Be provided with bolt in the said through hole, the two ends of said bolt are arranged on the outside of holder.
In sum, the beneficial effect of the utility model is: this linkage simple in structure, and utilize through hole that steel pipe is connected; Especially at the steel pipe of the intersection of different directions, increase stability of structure, can repeatedly utilize; And convenient disassembly, save the set-up time, increase work efficiency.
Description of drawings
The structural representation of Fig. 1 the utility model.
Mark and corresponding component title in the accompanying drawing: 1-through hole; 2-sleeve pipe; 3-groove; 4-holder; 5-tapped through hole; 6-through hole; 7-mount pad.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is done further to specify, but the embodiment of the utility model is not limited only to this.
Embodiment:
As shown in Figure 1, be used for the linkage of bridge construction process, comprise that the center is provided with the sleeve pipe 2 of tapped through hole 6, said sleeve pipe 2 is provided with mount pad 7, and said mount pad 7 is provided with through hole 1.Sleeve pipe 2 utilizes tapped through hole 5 that steel pipe is fixed to clamp, and through hole 1 is fixed the pipeline vertical with steel pipe simultaneously, makes steel pipe and pipeline link together, and increases the stable degree between them.
The center line of said through hole 1 is vertical with the center line of tapped through hole 5.Design has the function of cross buckle like this, and concrete angle can design various ways, selects the linkage of different angles according to the needs of job site.
Said sleeve pipe 2 is provided with holder 4 in the side away from mount pad 7, and said holder 4 is provided with groove 3.Groove 3 makes things convenient for bolt when unscrewing, to be rotated, and can change installation direction, makes that workman's operation is lighter.
4 are provided with through hole 6 on the said holder, and said through hole 6 penetrates the inside of groove 3, and the center line of said through hole 6 is parallel with the center line of through hole 1.
Be provided with bolt in the said through hole 6, the two ends of said bolt are arranged on the outside of holder 4.Bolt is as link, and sleeve pipe 2 and other parts and integral bridge are fixed, and makes all parts form an integral body, practices thrift installing space, and is more attractive in appearance in appearance.
Take aforesaid way, just can realize the utility model preferably.
