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 concrete filled steel tube coupled column, comprise: interior steel pipe column 1 and the steel bar column 2 that is set in described interior steel pipe column 1 periphery, described interior steel pipe column 1 is positioned at the middle part of described concrete filled steel tube coupled column, it is the column structure of hollow, described steel bar column 2 comprises that intersection is tied to many transverse reinforcements 21 and the Duo Gen longitudinal reinforcement 22 of one, and cast is provided with the concrete casting injection body 4 that is connected as a single entity with described interior steel pipe column 1 around it;
In the hollow chamber 11 of described interior steel pipe column 1 regeneration concrete pour mass 3. is set
Further, described regeneration concrete pour mass 3 is connected as a single entity with described interior steel pipe column 1.
Further, many longitudinal reinforcements 22 are arranged in the periphery of described interior steel pipe column 1 uniformly, are parallel to each other therebetween and along the bearing of trend setting of described interior steel pipe column 1;
Described many transverse reinforcements 21 evenly are socketed in the periphery of described many longitudinal reinforcements 22, and described many transverse reinforcements 21 and described many longitudinal reinforcements 22 are perpendicular.
Further, the cross section of described concrete filled steel tube coupled column is rounded or square.
Further, the cross section of described interior steel pipe column 1 is rounded or square.Below specifically introduce the Structural Tectonics of the utility model concrete filled steel tube coupled column.
Interior steel pipe column 1 is that the cross section is square or circular hollow cylinder structure, its square column steel pipe or cylinder steel pipe for being made by steel material, the cross section of interior steel pipe column 1 embodiment illustrated in fig. 1 is square, and the cross section of Fig. 2 and interior steel pipe column 1 embodiment illustrated in fig. 3 is rounded.
Be cast with regeneration concrete pour mass 3 in the hollow cavity 11 of interior steel pipe column 1, preferred embodiment in, regeneration concrete pour mass 3 links with interior steel pipe column 1 and is integrated, global sections is square or is circular.
Regeneration concrete pour mass 3 refers to adopt regeneration concrete to pour into a mould the bearing structure that forms, regeneration concrete comprises after discarded concrete block process fragmentation, cleaning, the classification, mix with grating by a certain percentage, partly or entirely replace the natural aggregates (mainly referring to coarse aggregate) such as sandstone, add again cement, water etc. and join the New Style Concrete Materials that forms.
By in the hollow cavity 11 of interior steel pipe column 1, being cast with regeneration concrete pour mass 3, improved the bearing capacity of concrete filled steel tube coupled column and anti-seismic performance and it has good endurance, fire resistance is good, easy construction, the advantages such as energy-conserving and environment-protective.
Preferred embodiment, many transverse reinforcements 21 are perpendicular with many longitudinal reinforcements 22.That is to say, many transverse reinforcements 21 and Duo Gen longitudinal reinforcement 22 are crossed as latticed hollow out body.Steel bar column 2 mainly plays the effect of strengthening bearing capacity, makes the integral body of concrete filled steel tube coupled column have certain anti-seismic performance and fire resistance.
Be understandable that, many transverse reinforcements 21 and Duo Gen longitudinal reinforcement 22 fixing concrete forms are not limited to above-mentioned square crossing and are grid-like fixed form, also can adopt the fixed form of other intersecting angles, can adopt connected mode commonly used to be fixed between the two; In addition, the shape of steel bar column 2 also can be configured to other outer shapes of above-mentioned square-section or circular cross-section.
4 cast of concrete casting injection body are arranged on the periphery of interior steel pipe column 1, and steel bar column 2 is coated wherein, and itself and interior steel pipe column 1 are coupled as one.During implementation, concrete casting injection body 4 employed strength grade of concrete are identical with concrete casting injection body 3 employed strength grade of concrete, and simultaneously internally steel pipe column 1 inside and outside pour into a mould, to improve the efficient of cast.Certainly, in Specific construction, concrete casting injection body 4 and concrete casting injection body 3 also can the different concrete of service rating intensity, also can pour into a mould respectively, do not affect the enforcement of this programme.
Be understandable that, the global sections of concrete filled steel tube coupled column can be for square, as depicted in figs. 1 and 2 the structure of embodiment; Also can be circle, the as shown in Figure 3 structure of embodiment.
Implement concrete filled steel tube coupled column of the present utility model, owing in the hollow chamber of interior steel pipe column the regeneration concrete pour mass is set, so that the concrete filled steel tube coupled column has larger lifting, good endurance in bearing capacity, anti-seismic performance and fire resistance.Can be applied in the highrise building of non-Anti-Seismic Region and Anti-Seismic Region, compact conformation, constructability is widely used.
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.
