These Issues Must Be Paid Attention to in the Curtain Wall Construction! -Ruminum Profiles Supplier

The building curtain wall has achieved long -term development in my country.

Some systems have reached or exceeded foreign standards, and many high -quality projects and high -tech projects have emerged. However, there are many projects, and even unavoidable security issues. Glass curtain wall is a widely used exterior wall system. The dominant position of the outer wall of the building is unshakable, and many high -quality projects have appeared.

1. Direct bonding of fluorocarbon coatings and structural glue some structural sealing and carbon fluoride coatings cannot meet the requirements of the curtain wall.

Therefore, measures should be taken to seams between the glass of the seal frame and the hidden framework curtain wall glass component and the seams of the coating plate of the carbide compound to improve the adhesion.

2. Self -attack screw connection Self -attack screw connection is conventional connection or positioning connection. As a structural connection, its reliability is poor.

3. The inner surface of steel and aluminum profiles (aluminum bag steel) is not easy to spray spray treatment in the inner surface of the square steel pipe. It is prone to quality problems when hot -dip galvanized, resulting in low erosion resistance. The gap between steel-aluminum matches should be relatively tight, otherwise the common force cannot be obtained, which will cause difficulty in preventing dual-metal electrochemical corrosion.

4. The short -voltage lid's light frame curtain wall uses a cover cover. On the one hand, it is easy to achieve an equal accent, and on the other hand, you can clamp it with a buckle cover. Using discontinuous caps (short pressure cap) can reduce costs, but problems such as static pressure cavity such as uneven glass and inability to form can occur.

5. The connecting parts between the beams use two -point connecting the curtain wall beams usually have "hanging heads". reasons may be:

(1) The bearing capacity of the beam does not meet the requirements;

(2) The connection between the beams and the pillars is weak. ) Due to poor resistance, the connection causes the curtain wall beams to twist.

6. Large cross -sectional decorative strips, dust on the upper surface of the large cross section decorative strip without drop water lines will appear.

If there is no drip line, it will cause more streams on the surface of the curtain wall.

If the dripping wire is set on the front end of the decorative bar, it can effectively prevent water and dust from flowing on the surface of the curtain wall. 7. The decorative cover of the decorative cover and the bayonet should be connected to the bayonet of the squeezing profile. The bayonet size is fixed, accurate, and can be reliable. The accuracy formed after the screw connection does not meet the requirements, and the connection is not reliable. 8. The hidden frame curtain wall adopts non -fixed distance board hidden frame curtain wall and semi -hidden frame curtain wall usually uses pressure plate (block) transmission force. The distance is generally not greater than 300mm. The pressure plate has a fixed distance and a non -fixed distance. After fixing the pressure plate with a fixing distance, the pressure gap is relatively fixed. The pressure on the glass panel and auxiliary plate is relatively constant, which is convenient for absorbing the deformation of structure and temperature, reducing friction and noise. extrusion. This will cause the image distortion on the glass panel. 9. The fake light box hidden box is not designed according to the hidden box wall design fake boxes usually install decorative strips on the seams of the dark frame curtain wall to play the decorative effect of the bright frame curtain wall. This structure should be designed with hidden frame -type curtain wall to design hollow glass and structural glue, that is, the second sealing glue should be seal with silicone structure glue.

If the polysulfe gel is used as the second sealing ring of hollow glass, although it may not be damaged under ultraviolet line, there are still unsafe factors.
