Description
Art
The utility model relates to the connecting structure of a kind of concrete column and stiffened steel structure post, is applicable to construction field.
Background technology
Conversion beam, for changing the structural configuration of architectural lower floor, is applied very general under construction.Stiffened conversion beam is high because of its bearing capacity, has applied widely at present.Stiffened conversion beam end should have stiffness transition mast to connect, and one is the connection violations problem avoiding shaped steel and column tie-bar, and two is ensure reliable beam-to-column joint and good transmission force property.As there is stiffened conversion beam, transition mast in the building that some floor heights are higher, transition mast that may be shorter just can ensure the connection of stiffness beam column, just there will be stiffened column and be suspended from situation in midair, this brings great difficulty just to the connection of stiffened steel structure and bottom concrete structure.If stiffened column is run through whole floor always, one is the waste of steel, and two is that shaped steel cross section is little, and time fixing, welded reinforcement contact surface is few, situation local stress being brought excessive to substructure; If adopt steel concrete stub to support stiffened column, the process complexity that contacts with shaped steel of formwork, form removal, concreting and concrete is uneconomical on the contrary repeatedly.
Utility model content
The purpose of this utility model is the above-mentioned deficiency overcoming prior art, provides a kind of constructability, the connecting structure of the concrete column reduced costs and stiffened steel structure post.The connected mode that the utility model provides, is convenient to the installation of stiffened column, easy construction, quick, can effectively reduce construction cost, shorten the construction period.Technique effect of the present utility model is as follows:
A kind of concrete column and stiffened steel structure post steel split heads connected node, for stiffened column (3) is connected to concrete column (2), it is characterized in that, described connected node comprises steel split heads (1), and described steel split heads (1) comprises steel post (9), brace (10), cross bar (11), crossbar (12), wherein, steel post (9) is distributed in periphery, plays main support effect; Brace (10), cross bar (11) adopts angle steel, is fixed on steel post (9), jointly forms a lattice column system with it; Steel split heads (1) is placed on concrete column (2), and stiffened column (3) is fixedly connected with steel split heads (1); Concrete (14) is had at concrete column (2), steel split heads (1) and stiffened column (3) upper.
The beneficial effects of the utility model are: the connection of steel split heads is a kind of construction measure of convenient construction, it can complete processing and fabricating in factory, on-the-spot employing welding is connected with steel superstructure, bottom and reinforcement welding are fixed, the most whole stiffness structure is cast in together, can be conveniently connected with stiffened steel structure post by concrete column.Reduce construction cost, accelerate speed of application, improve construction quality.

Detailed description of the invention
In FIG, the connected node of concrete column and stiffened steel structure post constructs and comprises, steel split heads 1, concrete column 2, stiffened column 3.
In fig. 2, when stiffened conversion beam 4, stiffened steel structure post 3 are constructed, first steel split heads 1 and floor 5 are welded and fixed, have the reinforcing bar 6 stretched out around, be integrally formed for concreting.Again the H profile steel 13 flange portions spot welding of top stiffened column is fixed on steel split heads 1, and with hawser 8, H profile steel 13 top and floor 5 is held, ensure its vertical verticality.The installation of stiffened conversion beam 4 can be carried out, the integrated poured connection completing concrete column 2 and stiffened steel structure post 4 of last formwork after H profile steel 13 installation.
In figure 3, steel split heads 1 comprises steel post 9, brace 10, cross bar 11, crossbar 12.Wherein, steel post 9 adopts i shaped cross section, has the corner that 4 are distributed in steel split heads, and construction working face is large, facilitates the fixing of steel split heads 1, plays main support effect.Brace 10, cross bar 11 adopts angle steel, is welded on steel post 9, jointly forms a lattice column system with it.At steel post 9 welded top two crossbars 12, contact area is large, in order to support top H profile steel, and provides stability.Steel split heads 1 top and H profile steel spot welding, bottom and reinforcement welding are fixed.The height of steel split heads and each scantling, according to actual requirement of engineering, are determined as the case may be.
In the diagram, stiffened column 3 comprises H profile steel 13, reinforcing bar 6 and concrete 14.
In Figure 5, concrete column 2 comprises reinforcing bar 6 and concrete 14.
