13 Knowledge Points That Cannot Be Ignored in Construction Curtain Walls in Construction-WJW Aluminum Supplier Aluminum

There are many details of the construction of the building curtain wall. If it is not valued, it will cause waste and rework, and serious hidden dangers will be buried.

1. When the curtain wall opens the fan key, the inside of the double -sided sticker is not scraped first. It can be seen from the outside of the glass. After a long period of time, the double batter or even the color changes, which affects the appearance.

2. Open fan -like fan, if there is no cutting experience, it is best to do a complete set of experiments. Otherwise, various materials shrinkage and hardware accessories will occur.

3. The aluminum alloy curtain wall opening frame 4mm is enough. The steel curtain wall opening frame must be combined with the actual situation, otherwise the welding joint and spray cannot be installed.

4. Open the window, generally do not need to install the handle. Press the processing order of the fan. Do not make holes. 5. The curtain wall column uses stainless steel bolts. Generally, the market and manufacturers generally use 201 materials. According to normal construction progress, the surface rust is generally not corrosive. However, it is easy to rust within 2 months after the keel installation.

6. The steel structure must be treated with zinc -rich primer before leaving the factory according to the standard. If it is a light steel structure, it is best to perform rust removal and primer on the spot. It is conducive to the control of the project site. At the same time, a construction team is also designed to reduce the phenomenon of leather rework.

7. The "curtain wall" of the curtain wall window must consider the matching of column width and wall width to ensure that the quality of the column and the indoor wall surface is preferably more than 50mm. Otherwise The indoor windowsill is too narrow and not beautiful.

8. In the corner of the ceiling, if you want to form a 45 -degree angle, the last grid on both sides must be the same, otherwise it will be severely damaged. 9. For buildings (yin horn, positive corners) with more angles, when drawing or dividing it into multiple pages of front maps, the angle of the landmark must be clearly clear, and sometimes there must be a schematic diagram line, which will lead to the faint error. Essence

10. Stone is similar to the drip tank of the window part, and there are many forms. If the tablet is to do an eagle-type seam, open the 10-15mm drip tank on the tablet; the vertical plate is 8-10 mm long, and 8-10 mm is hung behind the roof; Drops on the ground; the first is the most common, but the evaluation of the Luban award may not be qualified. The second is the simplest, but if it is burned stone, because the vertical plate of the lower mouth is easy to break, it is not good. For example, when the smooth stone is used in the second and second methods, pay attention to the thickness surface of the vertical plate edge plate, so it is necessary to do a good job of polishing.

11. Some novices will cut stone ceiling panels according to "Figure", but in actual installation, the connection end of the ceiling board and the side plate should be extended by 20 mm.

12. For some parts with deeper opening of the window, when placing panels around the lower opening, the impact of pan -water on the size of the panel should be considered. If it is not handled well, the inner corner sewing will be too large. In addition, the pan water in this specification is generally 2%. When the deep depth is less than 300mm, it is not 3 or 5mm at all. Take 10mm. It is reasonable and easy to accept. If the hole depth is large, the slope difference is 15mm, and the elevation of aluminum windows or curtain wall glass in the hole should also be increased accordingly, otherwise there will be too many taps; even if the fan is opened, the fan cannot be opened. In short, the construction diagram is so detailed.

13. When processing telescopic joints, the telescopic joint must be installed first, and then the profile must be installed, otherwise the telescopic joint construction will be inconvenient. Although there are some corresponding requirements for the training and employment of the construction staff of the curtain wall, the most common requirements are that the workers conduct the curtain wall installation operations under the oral guidance of the on -site or construction manager, without obtaining some related professional knowledge, and many on -site on -site on -site on -site Construction managers have only some curtain wall construction experience. Without systematic training, they can imagine construction risks and many disadvantages.
