Description
Technical Field
The utility model belongs to assembled steel construction field, concretely relates to steel pipe concrete frame assembled connected node.
Background
At present, the development of the Chinese steel market has great influence on the global steel market, the yield of the Chinese crude steel accounts for about half of the whole world in 2016 (49.6%), and the & lt thirteen five & gt assembly type building action scheme & gt is issued by the Ministry of housing and construction in 2017 in 3 and 28 months, so that more than 50 assembly type building demonstration cities and more than 200 assembly type building industry bases are cultivated. In 2018, the yield of Chinese crude steel is firstly broken by 9 hundred million tons and reaches 9.28 hundred million tons, and the yield is increased by 6.6 percent on a same scale.
The weld joint connection is the most main connection method of steel structures, and has the advantages of simple structure, no weakening of the section of a component, steel saving, reliable connection and the like; but the main defects are that the field welding workload is large, and the welding quality is not easy to ensure. In addition, the residual stress and residual deformation caused by welding have adverse effects on the structure, and the low-temperature cold brittleness problem of the welded structure is also more prominent.
The steel pipe concrete frame structure is the main structural form of a steel structure building, and the connection node between a steel beam and a steel column is one of the keys for ensuring that the structure has enough safety. In general, in the construction of a fabricated steel structure building, if a conventional connection method such as field welding is adopted, the workload of node connection is a high proportion. Therefore, to realize rapid site construction, mechanical connection nodes are required, and the workload of site connection is reduced to the minimum degree on the premise of ensuring the connection strength and rigidity.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a steel pipe concrete frame assembled connected node need not the on-the-spot welded steel pipe concrete frame full bolt assembled angle steel connected node.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a steel pipe concrete frame assembled connected node, is square stand and fixes the I-steel girder steel all around at the stand including the interface, the I-steel girder steel includes the first connecting plate along the perpendicular outside extension in stand side, the both ends of first connecting plate are equipped with second connecting plate, third connecting plate perpendicularly, the second connecting plate is parallel arrangement with the third connecting plate, the junction of first connecting plate, second connecting plate, third connecting plate and stand all is equipped with the angle steel, through the mutual fixed connection of bolt between first connecting plate, second connecting plate, third connecting plate, stand and the angle steel.
As a further improvement of the above technical solution:
the cross section of the angle steel is L-shaped and comprises a first fixing plate and a second fixing plate, mounting holes are formed in the first fixing plate and the second fixing plate, and bolts corresponding to the mounting holes are arranged on the first connecting plate, the second connecting plate, the third connecting plate and the stand columns.
According to the technical scheme, steel pipe concrete frame assembled connected node, simple structure, simple to operate had both avoided a large amount of on-the-spot weldment work, ensured the installation accuracy of welding quality and component location, made the work load of on-the-spot installation reduce the minimum, realized quick green construction, brought good economic benefits and social.
