The main components of curtain wall material

Date:2013-10-10 11:54 Click:
Walls mainly by reinforcing materials , decorative panels and sealing material composition . In order to improve the wall mounting and finishing , but also with en fixtures and other decorative pieces .
 
 
First, the matrix material
 
 
Skeleton is a curtain wall support system , it came load bearing surface layer , and then passed to the main structure of the load . Wall skeleton commonly used steel, aluminum alloy and stainless steel profiles and other materials produced primary and secondary keel, connectors and fasteners used to connect with the fixed .
 
 
1.1 Steel
More employment -shaped steel beam , angle, channel , square tube steel, steel -based materials to Q235 , such profiles high strength, low price.
 
 
 
 
1.2 aluminum extrusions
Mostly with a special aluminum alloy extruded aluminum-magnesium alloy extrusions, and after anodizing surface treatment. Material specification and section dimensions are based on the location of the skeleton , the mechanical characteristics and size of the decision, such profiles higher prices, but reasonable structure , easy installation , good decorative effect .
 
 
 
 
1.3 stainless steel profiles
Generally made ​​of stainless steel sheet stainless steel profiles manufactured into steel sash or mullions , high cost , size small.
 
 
1.4 connections , fasteners :
① fasteners. Fasteners are mainly chemical anchors, expansion bolts, stainless steel bolts , etc. ;
② connections . Connections use more angles, channels , steel processing, its shape depending on the application and for different parts of the curtain wall structure varies . Galvanized fittings should be used or be embalmed , to ensure that it has good corrosion resistance , durability , safety and reliability .
 
 
 
Two , Decking
 
 
Coat as building curtain wall , decorative panels directly reflects the effect of building facades effect , generally divided into the following decorative panels .
 
 
2.1 Glass
Float glass with both sides flat, smooth characteristics, excellent optical performance than glass ;
Heat-reflective glass through the sunlight reflected off the radiant heat to achieve insulation purposes ;
Mirror glass can shine in the sky near the scene and can produce rich facades ;
Heat-absorbing glass is characterized by the restriction can make visible with infrared heat through its affordable, more applications ;
Insulating glass with acoustic and thermal insulation function results.
There are also laminated glass, wire glass and tempered glass .
 
 
2.2 sheet metal
The metal plates are used for curtain wall aluminum , stainless steel, copper sheet, aluminum among the most widely used , more advanced construction with a stainless steel plate . There is a flat surface texture and bump checkered two kinds . Aluminum wall thickness of the sheet is generally about 1.5 to 2 mm , the bottom part of the building requires thicker , so that a strong impact resistance . In order to achieve the building envelope thermal requirements, both inside the metal wall panels and other materials for the use of mineral wool insulation materials and insulation .
 
 
2.3 Stone :
① granite . Granite is an igneous rock , the magma formed crystals . Its texture is small, three-dimensional patterns and crystallization feeling, the main component of feldspar, quartz and mica , high hardness, durable and long service life . The most widely used stone walls are granite .
    ② marble . Marble belong carbonate rocks , the sea was originally lime mud slowly deposited crystals become limestone ; crystals become larger hardens to form marble . Texture due to its impurities generated uneven , and by the formation of large-scale movement form a more lively sense of totem changes , the formation of the landscape like natural marble texture . Generally are some of the high-end villa project with marble walls .
 
 
Third, the sealing material
 
 
Sealing material for walls and sash and the frame grid grid gap between materials, such as filling materials , sealing materials and waterproof materials.
 
Polyethylene foam filler material to use tape or rubber bead .
 
Sealing material is used more rubber sealing strip, plate embedded within the border on both sides of the seal , buffering and fixed clamping effect.
 
Waterproof materials are mainly closed the gap and bonding , commonly used silicone sealant series . In the wall assembly , silicone rubber often used in conjunction with polyethylene foam tape , embedded polyethylene foam tape, outer sealing silicone rubber
