Abstract

The utility model discloses a ribbed square steel tube and a ribbed square steel tube concrete column. The ribbed square steel tube is formed by welding ribbed steel plates on which ribs are formed by rolling. The square steel tube is formed by welding four ribbed steel plates with the same length, or bending and welding one ribbed steel plate, or welding two ribbed steel plates bent to be at right angles. The ribbed square steel tube concrete column substitutes a traditional stiffening steel tube concrete column; compared with the traditional stiffening steel tube concrete column, the ribbed square steel tube concrete column has the advantages that because the ribs are formed by rolling, the welding workload and the machining cost are reduced, the machining time can be effectively shortened, and the quality stability is better.

Preferably, by four block lengths, identical ribbed steel is welded described square steel pipe, or is that a ribbed steel bent jointing forms, or is that two rectangular ribbed steels of bending are welded.

Preferably, the rib on described ribbed steel is distributed on the single or double of steel plate.

Preferably, the rib on described ribbed steel is continuous, or is interrupted, and/or rib is the horizontal parallel setting, or the dip-parallel setting.

Preferably, the identical ribbed steel welding ends separately of four block lengths that described square steel pipe adopts is offered groove, the groove opposite direction of every ribbed steel.

Preferably, the rib spacing on described ribbed steel is more than or equal to 10mm, the high 1.5mm that is more than or equal to of rib.

For achieving the above object, a kind of concrete-filled steel square tubular column with ribbing described in the utility model, by square steel pipe with ribbing, and inject the concrete column formation in this square steel pipe with ribbing, and wherein, described square steel pipe with ribbing is above-mentioned square steel pipe with ribbing.

The beneficial effects of the utility model are:

1, the utility model adopts concrete-filled steel square tubular column with ribbing to replace the conventional steel concrete column, has inherited all advantages of conventional steel concrete column, has the many advantages such as rigidity is large, bearing capacity is high, plasticity, good toughness, easy construction;

2, the utility model adopts concrete-filled steel square tubular column with ribbing to replace the conventional steel concrete column, than traditional concrete-filled steel square tubular column, existence due to rib, strengthened the stability of steel pipe, under certain condition, can relax the flakiness ratio limit value of steel pipe at bearing capacity, reduce thickness of steel pipe, save steel using amount, reduce costs;

3, the utility model adopts concrete-filled steel square tubular column with ribbing to replace the tradition steel core concrete column of putting more energy into, than the tradition steel core concrete column of putting more energy into, because rib is that rolling forms, welding job amount and processing cost have been reduced, can effectively shorten the processing duration, and quality stability is better.

The specific embodiment

Below in conjunction with Figure of description, the utility model is further described.

As shown in Fig. 1-7, the described a kind of square steel pipe with ribbing of the utility model embodiment, serve as reasons roll out rib 2 on steel plate ribbed steel 1 by being welded into the band fin steel tube of square.The utility model adopts square steel pipe with ribbing to replace the tradition steel pipe of putting more energy into, and than the tradition steel of putting more energy into, because rib is that rolling forms, has reduced welding job amount and processing cost, can effectively shorten the processing duration, and quality stability is better.

Described square steel pipe with ribbing, in manufacturing process, carries out steel plate continuous rolling on steel mill's milling train, at rolling surface, rolls out many ribs.

And on ribbed steel, the distribution of rib can have following several situation:

As Figure 1-Figure 4, the rib on described ribbed steel is distributed on the single or double of steel plate.

As Fig. 1, shown in Fig. 5-Fig. 6, the rib on described ribbed steel is continuous, or is interrupted; Rib is the horizontal parallel setting, or the dip-parallel setting.

Due to square steel pipe, on making, no matter be that turnup or bending are all more complicated, so, the ribbed steel complete to rolling further is operating as:

For four ribbed steel welding fabrications:

Four ribbed steels are all offered to groove on welding ends limit separately, wherein the two ends groove opposite direction on every ribbed steel; Four ribbed steels are carried out to adjacent groove face to be adjacent to and to weld together.
