In order to solve the problems of the technologies described above, embodiment of the present utility model provides a kind of compound cross-section concrete filled steel tube coupled column, comprise: be positioned at the steel pipe column at compound cross-section concrete filled steel tube coupled column middle part and be set in the outer steel pipe column of described steel pipe column periphery, the hollow region that enclosing forms between the middle part of described interior steel pipe column and itself and the described outer steel pipe column is jointly poured into a mould active fly ash concrete casting injection body is set.
Preferably, described active fly ash concrete casting injection body and described interior steel pipe column are connected as a single entity.
Preferably, the cross section of described interior steel pipe column is rounded.
Preferably, described active fly ash concrete casting injection body and described outer steel pipe column are connected as a single entity.
Preferably, the cross section of described outer steel pipe column is rounded or square.
Compound cross-section concrete filled steel tube coupled column provided by the utility model, because the hollow region that enclosing forms between the middle part of interior steel pipe column and itself and the outer steel pipe column is jointly poured into a mould active fly ash concrete casting injection body is set, improved compound cross-section concrete filled steel tube coupled column bearing capacity and compressive strength, can reduce the distortion of member, improved the ductility of member; Good endurance, easy construction, energy-conserving and environment-protective.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the cross section structure schematic diagram of embodiment one of the compound cross-section concrete filled steel tube coupled column of the utility model embodiment;
Fig. 2 is the cross section structure schematic diagram of embodiment two of the compound cross-section concrete filled steel tube coupled column of the utility model embodiment.
The specific embodiment
Below with reference to accompanying drawing preferred embodiment of the present utility model is described.
The utility model embodiment provides a kind of compound cross-section concrete filled steel tube coupled column, comprise: be positioned at the steel pipe column 1 at compound cross-section concrete filled steel tube coupled column middle part and be set in the outer steel pipe column 2 of described steel pipe column 1 periphery, the hollow region that enclosing forms between the middle part of described interior steel pipe column 1 and itself and the described outer steel pipe column is jointly poured into a mould active fly ash concrete casting injection body 3 is set.
Further, described active fly ash concrete casting injection body 3 is connected as a single entity with described interior steel pipe column 1.
Further, the cross section of described interior steel pipe column 1 is rounded.
Further, described active fly ash concrete casting injection body 3 is connected as a single entity with described outer steel pipe column 2.
Further, the cross section of described outer steel pipe column 2 is rounded or square.Below specifically introduce the Structural Tectonics of the utility model compound cross-section concrete filled steel tube coupled column.
In conjunction with referring to illustrated in figures 1 and 2, interior steel pipe column 1 is the rounded hollow cylinder structure in cross section, its cylinder steel pipe for being made by steel material, and the cross section of the interior steel pipe column 1 of two embodiment is rounded as depicted in figs. 1 and 2.
The inside of interior steel pipe column 1 is cast with active fly ash concrete casting injection body 3, preferred embodiment in, active fly ash concrete casting injection body 3 is connected as a single entity with interior steel pipe column 1.
Since active fly ash concrete casting injection body 3 and the combining structure of steel pipe can improve compound cross-section concrete filled steel tube coupled column bearing capacity and compressive strength, can reduce the distortion of member, improved the ductility of member; Meanwhile, this structure has good endurance, easy construction, the advantages such as energy-conserving and environment-protective.
Outer steel pipe column 2 is that the cross section is square or circular hollow cylinder structure, it is square column steel pipe or the cylinder steel pipe of being made by steel or stainless steel material, the cross section of the outer steel pipe column 2 of embodiment is square as shown in Figure 1, and the cross section of outer steel pipe column 2 embodiment illustrated in fig. 2 is rounded.
Outer steel pipe column 2 mainly plays the effect of strengthening bearing capacity, makes the integral body of compound cross-section concrete filled steel tube coupled column have certain anti-seismic performance and fire resistance.
Be understandable that, outer steel pipe column 2 also can be configured to other outer cross sectional shapes of above-mentioned square-section or circular cross-section.
The same cast of the hollow region that enclosing forms between outer steel pipe column 2 and the interior steel pipe column 1 arranges active fly ash concrete casting injection body 3, and active fly ash concrete casting injection body 3 and outer steel pipe column 2 are connected as a single entity.During implementation, the inside and outside cast active fly ash concrete casting injection body 3 of steel pipe column 1 simultaneously internally is to improve the efficient of cast.
Implement compound cross-section concrete filled steel tube coupled column of the present utility model, because the hollow region that enclosing forms between the middle part of interior steel pipe column and itself and the outer steel pipe column is jointly poured into a mould active fly ash concrete casting injection body is set, improved compound cross-section concrete filled steel tube coupled column bearing capacity and compressive strength, can reduce the distortion of member, improved the ductility of member; Good endurance, easy construction, energy-conserving and environment-protective.
Above disclosed only is the utility model preferred embodiment, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim still belongs to the scope that the utility model is contained.
