The unitized curtain wall is the outer wall of the building. It is not load-bearing and hangs like a curtain, so it is also called a hanging wall. It is a lightweight wall with decorative effects commonly used in modern large and high-rise buildings. The building envelope is composed of a structural frame and inlaid panels, and does not bear the load and effect of the main structure.
What are the installation requirements for the profile section structure of the unitized curtain wall?
What should I pay attention to when choosing a seal for a unitized curtain wall?
What needs to be done for the inspection and maintenance of the unitized curtain wall?
(1) Reasonably design the end face of the profile and the occlusal position of the profile, and try to separate the watertight line from the airtight line to ensure that the isobaric cavity plays a role.
(2) On the cross-section, avoid opening process holes during the production process as much as possible, and it is forbidden to open process holes on the wall of the airtight wire cavity.
(3) In the section design, special devices for transferring loads and actions should be set up on the vertical (or horizontal) members, and the airtight line rubber strips should be avoided as much as possible to transmit the force.
(4) In the section design of the plug-in unit curtain wall, it should be considered that there is a lap length of not less than 15 mm between the plug-in parts after the panels are installed. In order to have the ability to adapt to the displacement between layers and absorb the errors generated by on-site installation.
(5) When designing the section, consideration should be given to reserving a slot for installing the soft-covered water strip, so that a water-blocking barrier can be formed at the gap after the panel is installed.
(1) When designing the rubber strip, a reasonable cross-sectional form must be determined, and the appropriate EPDM rubber grade should be selected. The position and function of the rubber strip are different, and the cross-sectional form should also be different.
(2) When designing the rubber strip, the compression ratio and hardness must be reasonably determined.
(3) For rubber strips with special environmental requirements, it is necessary to jointly design with the rubber strip suppliers to make up for the lack of knowledge of the designers and make full use of the excellent performance of the rubber strip materials.
(4) The airtight line rubber strips of the butt-type unit curtain wall should be the same vertically and horizontally to ensure that the rubber strips are closed at the four corners of the plate.
1. According to the actual engineering experience, within one year after the completion and acceptance of the unitized curtain wall project, some defects in the processing and construction technology, materials and accessories of the curtain wall project are exposed to varying degrees. Therefore, the unitized curtain wall project is inspected once, and then every five years. The overall inspection and adjustment time of the unitized curtain wall shall be inspected once within half a year after the completion and acceptance, and thereafter, shall be inspected and adjusted every three years.
2. For the hidden frame and semi-hidden frame glass curtain wall using silicone structural sealant, the first bonding performance inspection shall be carried out after ten years of use, and thereafter, the inspection shall be carried out every 5 years.
Inspection every 5 years is based on good inspection results. If the bonding performance has a downward trend, the inspection interval should be set according to the inspection results and the inspection frequency should be increased.
