Curtain wall construction

Different curtain wall joint processing is also the focus of construction. According to the design drawings, the treatment measures at the joints of different curtain walls are as follows: fill the gap with foam rod and then fill with sealant. The glue surface should be flat and smooth. Stone and window interface parts belong to special parts. Therefore, the site involves the contact of different materials of stone and aluminum, and the waterproof here is particularly important. Therefore, in the window and stone contact part first in the internal filling of foam waterproof agent, to ensure the waterproof performance of the interface, after the foam agent dry, the gap between the stone and the curtain wall window is filled with silicone weather-resistant adhesive with excellent performance, to ensure that the gap is durable and impervious, with good waterproof performance. Stone slotting is an important key process, for this process to control the quality of the first is to ensure that the equipment is in the best working state, followed by the selection of serious and responsible, experienced operators for operation. Finally by groove detection, all do not meet the requirements of the process will be discarded, in order to ensure the safety of modern curtain wall. When the steel keel is installed, a stone slotting machine is put in, which is used for the on-site emergency stone plate slotting. Anticorrosion of steel structure is the key point of construction. The hardware fittings are made of stainless steel. When welding on site, the welding parts must be treated with anti-corrosion, and the thickness of galvanized coating should not be less than 75um. Steel corner codes and connectors shall be hot-dip galvanized. Exposed steel frame coating construction, rain, fog conditions can not be used (especially surface coating, strictly prohibited construction. The environment should be clean, the surface must be dry without moisture, the temperature should not be less than +15°C, and the relative humidity should not be greater than 60%. In the process of curtain wall construction, attention should be paid to the change of climate conditions. When there is strong wind, rain and fog, construction is not allowed (especially for surface coating, construction is strictly prohibited). The measurement of the axis of curtain wall partition should be coordinated with that of the main structure. For the error of the main structure, corresponding adjustment should be made in time to ensure that the processing and production conform to the actual situation on site: the measurement should be carried out under the condition that the wind is not more than level 4, and the position of the curtain wall should be checked regularly every day.
