Description
Technical field
It the utility model is related to construction engineering technical field, and in particular to a kind of curtain skeleton attachment structure.
Background technology
At present, two ways is predominantly spliced and welded in the connection of horizontal, vertical keel in the curtain wall of in the market.Wherein, splice
It is divided into two kinds again：One kind is subdivision mounting means successively, i.e., first installs first centre keel, then in first centre keel
Transom and centre keel are alternately installed in side successively, until completing the installation of whole curtain wall；Another kind be transom after fill mode,
All centre keels of curtain wall first are installed according to the size of space of setting, then the transom between adjacent centre keel is installed.On
The drawbacks of former mounting means stated, is, once error or other factors occur needs to change dragon after curtain wall installation
, it is necessary to which the later all keel in the replacing position are disassembled during bone, otherwise keel can not be taken out, and subdivision is successively
Easily there is accumulated error in installation, and larger deviation, example easily occurs in the split dimension between the centre keel for causing finally to install
Such as, the curtain wall installed from left to right has 50 separations, if the length of every transom reduces 3mm, each split dimension（It is adjacent
Spacing between centre keel）Also 3mm is reduced, last error accumulation can be up to 150mm.And latter mounting means due to be by
Transom between centre keel is installed again, only needing accordingly to dismount when changing any of which keel needs after centre keel whole installation
The keel to be changed, and this kind of mounting means is not in accumulated error.
However, the curtain wall technology filled after existing transom is ripe not enough, following many defects be present：
1st, the connector between keel and screw are difficult to hide, connector and screw largely it is exposed outside, not only influence
The installation of curtain wall panel, and make curtain wall install after outward appearance it is also not succinct exquisite enough；
2nd, the connector and screw number required for being connected between keel are more, cause to dismount that difficulty is big, efficiency is low, and also
Need to open up substantial amounts of fastening mounting hole on keel, the intensity of keel can be impacted, can also reduce the rust-preventing characteristic of keel
Energy.
3rd, the transmission for carrying out power is directly fastened between keel and connector by screw, bonding strength be present and be difficult to ensure card, easy
The problem such as low with security that fails is loosened, and screw is connected in the side wall of keel, stress balance and stability are poor, pipe
The side wall of shape keel is also easily deformed and breakage, and this just requires high to the wall thickness of keel, increases keel weight and holistic cost.
