(2) The curtain wall frame 12 adopts a steel-aluminum composite structure which has the characteristic of light weight, and because the curtain wall structure is more used for a large-span curtain wall structure, if a pure aluminum frame is used, the curtain wall structure can be designed into a solid form, the weight is larger, the cost is higher, and the curtain wall structure has no operability, so the problems can be avoided due to the light weight, and the installation is more convenient.
(3) The treatment of seams between different curtain wall frames 12 is also a construction focus of the project. The treatment measures of the joints between different curtain wall frames 12 are as follows: and filling a foam rod in the gap and then injecting a sealant. Before glue injection, protective adhesive tape paper is firstly stuck on two sides of a butt joint seam of glass, a foam rod is plugged, and the adhesive tape paper is immediately torn off after the glue injection is finished, so that the surface of the glass is prevented from being polluted during the glue injection.
If the stone of the curtain wall frame 12 and the window interface part belong to special parts. The location is thus related to the stone material being in contact with the different materials of the aluminium material and where water-proofing is particularly important. Therefore, the contact part of the window and the curtain wall frame 12 stone is filled with a foam waterproof agent firstly to ensure the waterproof performance of the interface, and after the foam agent is dried, the gap between the stone and the window is filled with silicone weather-resistant glue with excellent performance to ensure that the gap is durable and does not leak, so that the curtain wall frame 12 stone has good waterproof performance.
(5) Corrosion prevention of a steel structure: the curtain wall frame 12 is hot dip galvanized. Hardware fittings adopt stainless steel material. When welding is carried out on site, the welding part must be subjected to antiseptic treatment, and the thickness of the galvanized coating is not less than 75 microns. The curtain wall frame 12 and the like are hot-dip galvanized. When the steel frame is exposed, the steel frame cannot be constructed (particularly, surface layer coating is forbidden to be constructed) in the conditions of construction, rain and fog.
(6) The stress is ensured to be even, the computer is firstly used for typesetting, the high-precision steel ruler and the level gauge are used for positioning, and the corner connectors are tightly jointed. The BIM building information model technology is combined in the whole process, the simulation lofting and installation are carried out on the basis of relevant data, the error rate of processing and installation is strictly controlled, and the design, the construction period, the process and the like of the project are practically controlled, so that the overall effect of the project is ensured.
