Description
Technical field
Partial precast fashioned iron-the concrete combination column and its application that the present invention relates to a kind of based on side plate, belong to building skill
Art field.
Background technique
Composite structure it is many kinds of, in broad terms, composite structure refer to two or more different materials form one
Structure or component and cooperative structure (Composite Structure).Wherein, steel-concrete combined structure is after wood
The fifth-largest class formation to grow up after structure, masonry structure, reinforced concrete structure and steel construction.
It is partially filled with one kind that steel-concrete coupled column just belongs to steel-concrete combined structure, is referred to by I-steel or H
Fashioned iron-concrete combination column that fashioned iron and the concrete for being filled in two side wing edges are constituted, can give full play to steel and concrete
Material property embodies are as follows: the concrete in two side wing edge of coupled column is in three received strength shape by the package of the edge of a wing and web
State, has certain effect of restraint, the fashioned iron of coupled column due to fill concrete in the edge of a wing, can be effectively suppressed its local buckling or
The generation of overall collapse.
Therefore, steel-concrete coupled column is partially filled with due to high with intensity, rigidity, and the advantages such as fire resistance is good are being built
Build being concerned for 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
Trivial, this allows for the labour for being partially filled with steel-concrete coupled column and fund cost is apparently higher than ordinary reinforced concrete structure,
It greatly limits and is partially filled with the application of steel-concrete coupled column 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, which to substitute, is partially partially filled with steel-concrete coupled column, one
Surely can significantly solve it is existing be partially filled with complicated steel-concrete coupled column Joint's connection fabrication, splicing and template construction compared with
Cumbersome problem.
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.
Therefore, it is badly in need of designing that a kind of good stress performance, component stable connection, working procedure be few and simple, construction efficiency
High partial precast coupled column.

In shape steel web two sides fill concrete, the I-steel disadvantage weak along weak axis direction bending stiffness is improved, coupled column is improved
Comprehensive stress performance；Coupled column of the invention has given full play to the performance of two kinds of materials of steel and concrete, fills in fashioned iron mixed
Solidifying soil, the presence of fashioned iron enhance the effect of restraint to concrete, and the presence of concrete reduces fashioned iron and local buckling or whole occurs
A possibility that body unstability, thus increase the bearing capacity and ductility of coupled column, meanwhile, reach the mesh for reducing combination column cross-section size
's；Coupled column of the invention increases the bonding of cast-in-place concrete Yu two interfaces of fashioned iron using peg, guarantees that two parts are common
Work, and participate in undertaking xial feed, it is ensured that the normal use and bearing capacity of coupled column；The side plate of coupled column of the invention is
Corrugated plating, higher lateral rigidity had not only improved the effect of restraint to concrete, but also can guarantee and integrated prefabricated plate
It connects stronger；Therefore, when the height of coupled column of the present invention is 3000mm, sectional dimension is 350mm × 350mm, I-steel is cut
Face is having a size of 350mm × 350mm × 6mm, and when upper lower flange is with a thickness of 6mm, ultimate axial compressive strength is up to 5733.2kN, the limit
Anti-bending bearing capacity is up to 272.5kNm, ductility factor up to 4.02；
(2) the steel construction part of coupled column of the present invention can be by prefabrication, from heavy and light, and live concatenation construction is convenient, avoids
Traditional prefabricated assembled member dead weight is big, the difficult disadvantage of scene splicing；
(3) shaft of coupled column of the present invention uses water-proof heat preservation ornament integration prefabricated board, meanwhile, coupled column of the present invention
Integrated prefabricated plate also serves as non-dismantling formwork, both saves template, improves construction efficiency, and eliminate later period decoration of exterior wall engineering and height
The risk of idle job has certain economy, meets the development trend of present building industrialization and building energy conservation；
(4) tongue and groove is arranged at the integrated prefabricated plate place of being vertically connected in coupled column of the invention, can guarantee insulating layer and prevent
Effective connection of water layer, and can effectively prevent overflowing when concrete vibrating and starch the generation of phenomenon；
(5) the integrated prefabricated plate of coupled column of the present invention is anchored on flange plate by tap bolt, and protrudes into concrete
Certain distance further improves the firmness of integrated prefabricated plate to the effect that bonds of screw rod after casting concrete, increases
Its durability；
(6) coupled column of the invention does not use reinforcing bar, on the one hand reduces steel using amount, and eliminates cumbersome reinforcing bar side
Bundle process.
