Curtain wall back cover anti-settling mechanism
Technical field
The utility model relates to a kind of anti-settling mechanism, particularly a kind of curtain wall back cover anti-settling mechanism.
Background technology
Building, Building one begins to build up to the building from construction, and along with the increase gradually of construction load, ground is all producing sedimentation constantly, and this sedimentation generally will could finish after the building builds up 2 years.Like this, the cladding glass that install the outside, building is easy to take place damaged when building settlement, influences the application life of cladding glass, and can produce safety problem.
The utility model content
It is a kind of rational in infrastructure, safe and reliable that the purpose of this utility model is to provide, and can absorb the sedimentation of building, reduces because of the curtain wall back cover anti-settling mechanism of building settlement to the threat of cladding glass.
The purpose of this utility model can reach by following measure: a kind of curtain wall back cover anti-settling mechanism, comprise curtain wall base cross members, cladding glass, it is characterized in that: also have back cover splicing section bar, curtain wall back cover section bar, the fluid sealant of anti-marquis, expansion bolt, curtain wall back cover section bar fixes on the ground by expansion bolt, back cover splicing section bar top is connected with the curtain wall base cross members, bottom and the interlocking of curtain wall back cover section bar, and scarf seals with the fluid sealant of anti-marquis.
The purpose of this utility model can also reach by following measure: the space in back cover splicing section bar and the formation of curtain wall back cover section bar is built-in with heat preservation rock.
The utility model has following advantage compared to existing technology: rational in infrastructure, safe and reliable, can absorb the sedimentation of building, and reduce because of the threat of building settlement cladding glass.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):
With reference to Fig. 1-Fig. 4, the utility model comprises curtain wall base cross members 1, cladding glass 2, back cover splicing section bar 3, curtain wall back cover section bar 4, the fluid sealant of anti-marquis 5, expansion bolt 6, heat preservation rock 7 etc.Curtain wall back cover section bar 4 fixes on the ground by expansion bolt 6; Back cover splicing section bar 3 tops are connected with curtain wall base cross members 1, bottom and 4 interlockings of curtain wall back cover section bar; And scarf seals with the fluid sealant of anti-marquis 5.Be built-in with heat preservation rock 7 in back cover splicing section bar 3 and the space that curtain wall back cover section bar 4 forms.When sedimentation takes place building, between back cover splicing section bar 3 and the curtain wall back cover section bar 4 relative motion can take place, thereby can absorb the sedimentation of building.
