Description
Technical field
The utility model is related to a kind of end plate assembled truss of angle steel beam column node connection device for recovering function, belongs to
Technical field of structural engineering.
Background technology
China's unit construction area energy consumption is more than 2 times of developed country, and building waste, construction dust are that city is mainly dirty
One of dye source.The development of China's light-duty steel construction house faces major opportunity, and China is used as 700,000,000 tons of the first in the world Chan Gang big countries, production
Can be superfluous nearly 100,000,000 tons, but steel building only accounts for 5%, and developed country accounts for more than 50%, Housing Guarantee speed,
Earthquake calamity area house rebuilds speed and needs further raising.In order to promote the scientific development of the steel structure system, it is ensured that design, construction
Safety is, it is necessary to carry out scientific and reasonable research and development, the theory analysis of system and experimental study to the system, to realize setting for the product
Meter standardization, production industrialization, installation mechanization, solve product the problem of design, production, installation and acceptance several respects, full
Standard criterion of the foot country in construction field.
Violent earthquake for several times in recent years shows that the mankind still suffer from comprehensive threat of earthquake, and China is located in Pacific Rim
On earthquake zone and Mediterranean Himalaya earthquake zone, frequently, Wenchuan and cajaput violent earthquake are caused huge to China for seismic activity
Loss, brings bitter lesson.Hereafter, modified beam-column connection turns into the heat of countries in the world steel construction research field
Point.Experimental and theoretical study shows, the purpose of plastic hinge when these modified nodes can reach macroseism, it is to avoid node mistake
Early there is crack and occur brittle break, but after macroseism, the steel frame of these nodes can all produce larger residual deformation,
Structure and the deformation of member are larger, are difficult to recover function of seismic resistance after shake, or even be difficult to repair or rehabilitation cost is greatly increased.This makes one
Have to examine closely and seek again more preferable structural system, thus functional structure can be recovered after proposing shake, for hospital etc.
Important building, lifeline engineering are proposed should be from anti-fall structure of collapsing to can recover the structure transformation of function after shake.It can recover after shake
Functional structure refers to be not required to repair or slightly repair after earthquake (set up defences or shake greatly) that its structure for using function can be recovered.
Therefore, the utility model proposes the end plate dress that can recover function after a kind of shake for belonging to technical field of structural engineering
With formula truss of angle steel beam.Its object is in the production and construction of steel structure system, by modularization, batch production is standardized, dress
It is combined with changing and functionalization can be recovered, at the scene during construction application, the space composition structure of girder truss provides larger sky
Between, beneficial to running through for pipeline, bring great convenience and advantage, while factorial praluction is realized, live quick assembling,
On the premise of ensureing construction quality, speed of application is improved, reducing the construction period, and change Local Members just can realize knot
The quick reparation of structure, rather than the collapse resistant capacity of single pursuits structure completely, so give full play to assembling type steel structure oneself
Body advantage, considerably reduces construction costs.Meanwhile, the splicing of two girder trusses is easy to implement girder truss and floor factory-assembled
Shaping form modular assembly unit, then at the construction field (site) each modular unit by girder truss with cantilever beam section quadrate steel pipe column
