Figure；Fig. 5 is a kind of partial structural diagram of the cross section of the open column of anti-buckling unstability provided in an embodiment of the present invention；
Fig. 6 is a kind of partial structural diagram of the cross section of the open column of anti-buckling unstability provided in an embodiment of the present invention.This
The open column of anti-buckling unstability provided by inventive embodiments can be applied on cell cube curtain wall, the open column
On the symmetry axis S for cutting the cross section that the heart 5 is located at the open column with centroid 6 of cross section, the abdomen of the open column
Portion is provided with the ribbed stiffener 4 of protrusion；The open column includes public column 1 and female column 2, the public column 1 and the mother
It is connected between column 2 by profile (301,302).Wherein, centroid 6 refers to the geometric center of member section, only the shape with section
Shape is related with size；It cuts the heart 5 and refers to that component is only when the position of lateral load is by a certain particular point on member cross-sections
Curved not turn round, then the point cuts the heart 5 for section.
Due to the open column cross section centroid 6 and cut 5 position of the heart on one wire so that open column
Cross section avoid rotating, mutually reversed after avoiding public column 1 and female column 2 from connecting, the heart 5 is cut in the cross section of open column
Need constantly adjustment that can just make on symmetry axis S of the two in the cross section of open column with the position of centroid 6.It is complete in principle
Being open between the public column 1 and female column 2 of column is grafting, and the cross of open column must be taken into consideration in the actual operation process
There is cutting the heart 5 in section and centroid 6 deviates, even if public column 1 and female coupling of column 2 are together, due to and non-real connection,
The problem of still will appear the changing of the relative positions between public column 1 and female column 2, it is therefore desirable to keep the centroid of the cross section of open column
6 are overlapped with the heart 5 is cut, and reduce the torsion between public column 1 and female column 2.Wherein, the determination of the centroid 6 in column section can pass through
Some small softwares obtain, such as UG, but the solution for cutting the heart 5 needs special finite element software, such as ANSYS, then passes through CAD
Approaching face domain, inquiry beam element torque characteristic one can determine the position for cutting the heart 5 of the cross section of open column.
The profile (301,302) being arranged between public column 1 and female column 2 prevents public column 1 and female column 2 positive and negative
The phenomenon that gliding under wind pressure can also make open column form the box-type section of a similar closed chamber, greatly strengthen
The total bearing capacity of open column.In addition, the abdomen along 2 section of public column 1 and female column that is open is uniformly arranged multiple protrusions
Ribbed stiffener 4, enhance the local buckling bearing capacity of open column.
In some embodiments of the open column of anti-buckling unstability of the invention, such as in the present embodiment, such as Fig. 2 institute
Show, the clearance G 1 connected between the profile and the public column 1 need to meet the following conditions: G1≤2mm, such as the clearance G 1
It can be 2mm；The gap G2 connected between the profile and female column 22 also needs to meet the following conditions: G2≤2mm, such as institute
0.5mm can be taken by stating clearance G 2.For profile during carrying out grafting with public column 1 and female column 2, profile should be with public column 1, mother
Gap between column 2 controls within 2mm, and within the scope of this standard is allowed as error, prevents public column 1 and mother from standing
Column 2, which is separated from each other or draws close, there is excessive shake.
Further, in some embodiments of the open column of anti-buckling unstability of the invention, such as the present embodiment

The other end is embedded in second groove 2002.
Existing profile can only make column play anti-wind action under positive wine pressure, and between public column 1 and female column 2
Gap is excessive, needs with female deformation of column 2 to connect public column 1 by profile；In addition, under the conditions of negative wind pressure, it is existing
Profile all column can not be made to play anti-wind action.Only make under the conditions of positive wine pressure to solve anti-skidding profile in the prior art
Column plays windbreak function, and the present invention carries out special designing to profile, the open in the present invention is made under the conditions of positive and negative wind pressure
Column plays windbreak function.
Further, the lower end surface of the end on first edge of a wing 101 is provided with the first chamfering 1012, and described second is anti-
The upper surface of the end of water baffle 202 is provided with the second chamfering；The first anti-skidding profile 301 is buckled in first chamfering
On 1012, the second anti-skidding profile 302 is buckled in second chamfering；The section thickness on second edge of a wing 201 compares institute
The section thickness for stating first edge of a wing 101 thickeies 1mm.In order to meet the centroid 6 in column section and cut the symmetry axis that the heart 5 is in section
On, usually make the length on second edge of a wing 201 less than the length on first edge of a wing 101 in actual application, therefore, it is necessary to
The thickness in the section on two edges of a wing 201 carries out thickening processing, and the thickness in the section on heretofore described second edge of a wing 201 is relative to institute
The thickness for stating the section on first edge of a wing 101 thickeies 1mm.
