Description
Technical field
The partial precast coupled column that the present invention relates to a kind of based on batten plate and its with the connection method of beam, belong to Building technology
Field.
Background technique
It is partially filled with the concrete structure that steel-concrete coupled column refers to by I-steel or H profile steel and be filled in two side wing edges
At fashioned iron-concrete combination column, it can be understood as the combination of steel construction and concrete structure can give full play to steel and coagulation
The material property of soil embodies are as follows: concrete in two side wing edge of coupled column by the package of the edge of a wing and web be in three-dimensional by
Power state has certain effect of restraint, and the fashioned iron of coupled column can be effectively suppressed it and locally bent due to fill concrete in the edge of a wing
Bent or overall collapse generation.Therefore, it is high with intensity, rigidity to be partially filled with steel-concrete coupled column, it is excellent that fire resistance is good etc.
Gesture, in being concerned for building field.
But it need to be using thick and heavy fashioned iron as important primary structure member, to guarantee due to being partially filled with steel-concrete coupled column
It is effectively connected, and the general construction complexity of node connection, splicing and the template construction for being partially filled with steel-concrete coupled column are more numerous
It is trivial, cause its labour and fund cost to be apparently higher than ordinary reinforced concrete structure, limits its application in practical projects.
Prefabricated construction is a kind of new structure spliced by prefabrication primary structure member, construction site, in advance
Assembly concrete coupled column processed is a part in its structural system.Since the main member of prefabricated construction is in factory
Production eliminates a large amount of form work engineerings in conventional concrete construction construction, and component quality is more secure, can be effectively improved
Construction environment is widelyd popularize by country in recent years.Therefore, if prefabricated assembled concrete coupled column can be used to substitute portions
Divide filling steel-concrete coupled column, centainly can significantly solve the existing steel-concrete combination Column border node that is partially filled with and connect structure
Make complicated, splicing and the cumbersome problem of template construction.
But the prefabricated assembled member dead weight of tradition is big, scene splicing is difficult, wants to site operation personnel and execution conditions
Ask higher, and prefabricated components node region still needs to build template, work progress and simplification not yet in effect, the cast-in-place area of this exterior node
There are the congenital problem such as bond-slip, leak, the use of structure and stress performances to be had for the connection of domain and prefabricated components
Effect ensures.
