Xiantao City Facade Glass Inspection: The specified年限 for facade glass inspections are as follows: One year after the facade project is handed over for acceptance, an inspection should be conducted once. Subsequently, inspections should be carried out every five years. The inspection items should include:
1. Check for any deformation, misalignment, or loosening in the curtain wall as a whole; if found, further inspect the concealed structure corresponding to the affected area. Also, examine the main load-bearing components, connecting elements, and bolts for any damage, connections, or rust.
2. Is there any looseness or damage to the glass panel?
3. Check for any sealant detachment, cracking, or bubbling, as well as any damage to the sealant strips, such as detachment or aging.
4. How flexible is the opening and closing of the section? Are there any functional issues or damage with the hardware accessories? Are the installation bolts or screws loose and worn out?
5. Is the facade drainage system unobstructed?

Xiantao City facade glass testing requirements for curtain wall windows and doors samples:
The materials used in the sample and the manufacturer, specifications, and model used in the actual engineering are consistent. The assembly of the sample must comply with design requirements and no special accessories may be added or other measures taken.
The width of the sample should at least include one vertical component bearing the design load, at least three vertical load-bearing rods, and two divisions. The height of the sample should at least include one floor height, and should be connected to the load-bearing structure at two or more points vertically. Based on the actual floor height of the windows, doors, and curtain wall project, and the distance between the vertical concrete embedment pieces of two adjacent floors, determine the length of the vertical load-bearing rods to ensure that the length of connection with the actual load-bearing structure in the vertical direction is the same. The stress condition of the sample assembly and installation should be consistent with the actual situation.
The unit point-supported curtain wall should include at least one typical cross-seam that matches the actual project, as well as a complete unit's rectangular seam identical to that of the actual project.
Samples should include typical vertical seams, horizontal seams, and hinged sections, with the proportion of the hinged section on the sample's total area closely resembling the actual project.
The contractor should pre-adhere the subframe of the concealed glass curtain wall to ensure the structural adhesive dries thoroughly during the sample installation in the laboratory.
Once the columns, beams, glass with adhesive subframes, and other components for the inspection sample are prepared, under the supervision of the project supervisor, they will be delivered to the testing room for installation. The installation must comply with design specifications and the installation direction and load conditions must match the actual project. After testing, the test samples will be removed.
