Curtain wall embedded parts is not hot galvanized is not important, the key you have to come up with convincing anti-corrosion measures, perhaps with the development of science and technology have a better way to deal. However, it is still economical and convenient to deal with this at present. It is not necessary to galvanize the embedded parts of curtain wall before knocking out. After knocking out, brush antirust paint once. After welding the corner code, brush antirust paint twice and silver paint once. Remember to clean with a wire brush before the first paint. Steel anchor plate galvanized should affect the welding quality, large rigid connection of steel structure are not galvanized. After the anchor bar is galvanized, the grip force between the embedded parts and the concrete is reduced, and the bearing capacity of the actual embedded parts is also reduced. The exposed part of the embedded part is hot-dip galvanized, while the anchor bar is not galvanized, but this is difficult to do, or not at all.

Because the steel bar is on the concrete facade, it is protected by concrete, and the embedded parts are exposed, and there are operations on the embedded parts. The specification requires that the exposed steel must be galvanized. To sum up, the front embedded parts do not need to be galvanized, and the bond strength between the galvanized parts and the concrete is reduced. Before construction, the front embedded parts can be cleaned and painted with antirust paint. The cost is inefficient and the fruit is good! The rear embedded parts must be galvanized, because the uniformity and tightness of the anti-rust paint are not as good as the galvanizing effect! Galvanizing is only a means of anti-rust, galvanizing is not the purpose, the purpose is to prevent rust!

At present, many projects have the requirement of curtain wall. A complete and regular curtain wall needs to be arranged and installed inside and outside the wall. In order to achieve aesthetic effect, care should be taken in the whole construction process and various specification requirements should be strictly observed. Curtain wall embedded parts specification is one of the specifications that must be observed in the construction process.

There are many specification requirements for curtain wall embedded parts, which can be specifically summarized into several important points: choose embedded parts according to design requirements, not all curtain walls choose embedded parts. Second, the pre-burial time should be planned, not random. Third, the embedded position, depth, etc. should be reasonably designed, and construction should not be started at random. Fourth, the embedded parts need to be treated professionally, and anti-corrosion treatment is the basic processing requirement. The construction party must ensure that all embedded parts used are purchased from regular curtain wall embedded parts manufacturers, and only products with clear routes and reliable quality can be applied to curtain wall construction.

At present, the stone materials used for curtain wall embedded parts are naturally formed. Natural stone materials are mined from mountains. Its important performance depends on mineral composition and structure. However, the above-mentioned series of performance tested by sampling have differences in each sample, which is not as small as industrial products. In recent years, with the development of social economy and the improvement of urban appearance, the stone curtain wall has been favored by the majority of owners and architects in the exterior decoration of buildings, and has occupied a considerable proportion in the existing buildings.

Near the popular stone curtain wall, all major buildings have exterior wall stone dry hanging, but due to construction technology and other reasons, factors can not be ignored. Due to various reasons, the selection of slate, dry hanging glue, dry pendant and the production and installation of embedded parts are easy to be ignored, and this paper briefly analyzes how the four materials should be selected. Due to different sampling surfaces, the measured performance will not be exactly the same.

Therefore, the height of the application of stone curtain wall is getting higher and higher, and the volume is getting larger and larger; more and more varieties of stone are used, from the original single granite to marble, limestone, sandstone and other varieties; the shape is becoming more and more complex, The requirements for installation and construction technology are getting stricter and stricter, and the requirements for sex are getting higher and higher. However, the domestic market of stone curtain wall materials is chaotic, the production technology of construction units lacks technical specifications, and the technical quality of construction personnel is low, all of which bring great hidden dangers to the project.

As the outer retaining structure of the stone curtain wall, it does not bear the load of the main structure, but it is in the outer surface of the building, in addition to bear its own weight, but also bear the influence of wind load and earthquake action and temperature change, so the stone must be reliable. The performance and quality requirements of stone include: compressive strength, flexural strength, bending strength, hardness, wear resistance, frost resistance, fire resistance, workability, etc.
