Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described in detail.

As shown in Figure 1 and Figure 2, the utility model comprises two channel-section steels 1,2 to crimping in spaced cold bending thin wall C type band, wherein the both wings of a pair channel-section steel 1 are welded on another two apotomes to channel-section steel 2, and then the utility model inner surface surrounded an elongated cavity 3, shaped steel that the every side of external surface has an elongated notch, the cross sectional shape of this cavity 3 can be square, also can be rectangle.

As shown in Figure 3, the utility model can use as the column 4 of building structure, also can use as the girder 5 of building structure, can also use as the secondary beam 6 of building structure.Because the utility model adopts standardized production, although the utility model cross-sectional configuration is all identical, but according to the difference of building structure instructions for use, various different specification series can be designed, like this in the job site of building structure, the component of same size series can exchange use, installs very convenient, and saves time.

Embodiment 1:

As Figure 1 and Figure 4, when the utility model uses as column 4 and girder 5, column 4 and girder 5 are welded with along the length direction interval of shaped steel some brackets 7 and the junction plate 9 with installing hole 8.Supporting surface 71 along the spaced bracket of shaped steel length direction 7 on column 4 is vertical with the length direction of shaped steel; And supporting surface 72 along the spaced bracket of shaped steel length direction 7 on girder 5 is parallel with the length direction of shaped steel.Just can distinguish column 4 or girder 5 according to the supporting surface 71,72 of bracket 7 from the different of shaped steel length direction like this, if simultaneously shaped steel does not arrange bracket 7, just can judge that this component is secondary beam 6 (as shown in Fig. 3, Fig. 5).

Embodiment 2:

As shown in Figure 4, Figure 5, when the utility model uses as girder 5 or secondary beam 6, because its two ends need to be connected with two adjacent columns or two girders, therefore need to weld the head plate 11 with installing hole 10 respectively at two ends of the present utility model.Simultaneously due to secondary beam 6 be arranged on girder 5 time, secondary beam 6 is seated on the supporting surface 72 of bracket 7, and is fixed by the installing hole 8,10 of bolt through junction plate 9 and head plate 11, and therefore the top of secondary beam 6 is concordant with the top of girder 5.According to this feature, can judge that whether secondary beam 6 is supporting with girder 5; In addition can also according to column 4 and girder 5, or girder 5 be oppositely arranged with secondary beam 6 junction plate 9, head plate 11 judges whether matching used component coordinating of installing hole 8,10.

Embodiment 3:

As shown in Figure 6, when the utility model is for making multistory building, needing column 4 to lengthen, like this, a dull and stereotyped (not shown) can be welded in column 4 upper cavity 3 of lower floor, flat board supports a sleeve pipe 12; Sleeve pipe 12 is integrally welded with the port junction of lower floor's column 4 cavity 3, and weld a transverse channel steels stiffening plate 13 respectively at each notch place of upper and lower two column 4 ends, the top of transverse channel steels stiffening plate 13 and bottom are all provided with connecting hole 14 simultaneously.When two columns 4 carry out lengthening connection, as long as the sleeve pipe 12 cavity 3 of upper strata column 4 bottom being overlapped column 4 top below makes two columns 4 engage, then fix with nut through after four connecting holes 14 that upper and lower each transverse channel steels stiffening plate 13 is relatively arranged with each bolt successively; By that analogy, until reach the design height requirement of building structure.

Embodiment 4:

As shown in Figure 7, Figure 8, when the utility model uses as the column 4 of the bottom, need to be connected with the suspension column 15 that the applicant designs in addition.This suspension column 15 comprises base plate 151, sleeve pipe 152, four vertical channel-section steel stiffening plates 153 and four ribs 154.Sleeve pipe 152 passes base plate 151 center and is welded thereon, the sleeve pipe 152 be positioned at above base plate 151 inserts the cavity 3 of column 4 bottom, base plate 151 is welded on the bottom of column 4, weld a vertical channel-section steel stiffening plate 153 respectively at each notch place of column 4 bottom be connected, then four ribs 154 are welded between base plate 151 and vertical channel-section steel stiffening plate 153 respectively.The sleeve pipe be positioned at below base plate 151 is inserted on corresponding basis, and is fixedly connected on basis by base plate 151 by chemical bolt 16.

In the various embodiments described above, the utility model adopts galvanizing thin-walled cold-rolled steel sheet to be that base material is made.

The various embodiments described above are only for illustration of the utility model; wherein the structure, connected mode etc. of each parts all can change to some extent; such as installing floor plates, roof panel, inside and outside wall board etc.; the routine that the basis of technical solutions of the utility model is carried out and equivalent arrangements and improvement, all should not get rid of outside protection domain of the present utility model.
