Description
Technical field
The present invention relates to a kind of new filling wall and the varied rigid link technique and device of chassis body.
Background technology
Filling wall is tiltedly built with Vierendeel girder using filling wall top on vertical with chassis body and held out against, and leads in the horizontal direction
Cross steel tie to strengthen filling contacting between wall and frame column, this connection is exactly so-called rigid connection.Pass through
Certain gap is set between filling wall and chassis body, in the deformation range that framework allows, filling wall is not involved in ground
The distribution of shake effect, here it is so-called flexible connection.
Be rigidly connected shortcoming：Under big shake effect, filling wall can produce extremely disadvantageous influence to framework：1. increase structure
Rigidity (presence of filling wall makes the initial stiffness of structure increase 5 to 10 times), dramatically increases the geological process of total；
2. in Practical Project, because building is using the need for function or the factor such as the later stage reconstructs, wall is in plane and is vertically arranged for filling
When, always inevitably occurs a certain degree of irregular, makes structural floor stiffness variation uneven and forms weak floor；3.
Wall beam acts on forming frame short span beams, realizes expected " strong column and weak beam " mechanism difficult, causes structural collapse；4. in geological process
Under, filling wall constrains the side-move distortion of framework post part shell of column so that local anti-side rigidity is excessive, and the seismic shear shared is unexpected
Increase, often leads to short column destruction；5. be rigidly connected, filling wall participates in agent structure stress, and its own lateral deformation stiffness is big,
Assigned seismic force is also big, and fill wall building block and mortar tensile strength it is all relatively low, the adhesion strength at its interface
It is relatively low so that filling wall is easy to cracking or even collapsed under geological process.In a word, the filling wall that is rigidly connected is difficult to realize specification
The target of setting up defences of " big shake less than " that proposes.
It is flexibly connected shortcoming：Under small, middle shake effect, led due to not connected reliably between filling wall and beam, post
The situation for causing filling wall full wafer to collapse or throw away is a lot, in 5.12 Wenchuan earthquakes, and the main body of many frame structures damages lighter,
And it is very serious to fill wall destruction.Beneficial Effect (the rigidity effect of filling wall of filling wall rigidity effect is not made good use of not only so
Should reduce main body displacement, mitigate the destructiveness of structural elements and non-structural element significantly), also cause what specification was proposed
The target of setting up defences of " no damage in small earthquake, middle shake can be repaiied " is difficult to.
In one's early years, when earthquake occurs, if being only that the non-structural elements such as filling wall are destroyed, lose and little；In recent years
With the raising of decoration technology, the ratio that non-structural element cost accounts for building total cost constantly increases, the destruction meaning of filling wall
And have lost the 50% to 70% of building total cost, and repair extremely difficult；Therefore, the ground of the non-structural element such as concern filling wall
Shake safety is particularly important.
The content of the invention
It is actual based on engineering it is an object of the invention to overcome the deficiencies of the prior art and provide one kind, it will be rigidly connected
Combine with the respective advantage of flexible connection technology and explore a kind of new technology, keeping the same of easy construction that be rigidly connected
When, also there is the connected mode for being flexibly connected superior anti-seismic performance, a kind of reasonable varied rigid link device is proposed, to ensure non-knot
The requirements for fortification against earthquake of structure component filling wall " no damage in small earthquake, no collapsing with strong earthquake ".
