How to deal with uneven joints of building curtain wall glass?
Building curtain wall glass should check the appearance quality of the panels to be used according to the standard rules, including standards, dimensions, flatness, angles, appearance defects, etc. Those that exceed the allowed error will not be used. So, how to deal with uneven joints of building curtain wall glass?
The finishing surface is uneven, and the joints are uneven. It means that after the granite slab wall is embedded, it is found that there is a large area of unevenness, uneven joints horizontally, uneven vertically, different joint widths, and uneven adjacent panels. It does not meet the board wall engineering specifications and seriously affects the appearance of the wall.
When the granite wall is uneven alone, these panels can be directly corrected or replaced, which is convenient to handle. If a large area is uneven and the joints are not straight, it is difficult to handle, and the rework time and capital costs are very high. It is necessary to pay attention to prevention.
If the joint is not straight and the situation is not serious, you can find it directly along the joint line (a level and theodolite should be used for large areas), and use the method of appropriately increasing the width of the joint. Use fans to pop up the joint line after the joint is enlarged, and paste color separation tape along the joint line. Use bright waterproof sealant. For the plates to be used, the appearance quality should be tested according to the specifications. The test content includes standard, size, flatness, angle, appearance defects, etc. Those that exceed the allowed error shall not be used. Batch plates should be processed and produced by stone factories. The backward method of not using batch production plates on the construction site should be processed and produced by special equipment of stone factories (such as computer numerical control machine tools).
Make a construction drawing and strictly follow the drawing. Before installing the plate, the actual size and error of the plate installation part should be carefully checked according to the requirements of the architectural planning drawings, and a correction drawing should be made. When the allowed error is exceeded, when the grouting method is used for construction, and when the distance between the base and the plate surface is more than 30mm, it is necessary to rearrange the block size.
Special decoration planning is carried out for wall panels, and the drawings are carefully reviewed to clarify the arrangement, grid, and pattern of the panels. The location of the expansion joints, the joints, and the structure of the concave and convex parts are roughly the same. There is no waterproofing requirement for indoor walls. The dry joints of the smooth and mirrored granite slabs are the main reason for the uneven joints. Waterproofing requirements are required for outdoor walls, and the width of the board joints shall not be less than. For projects with high requirements for inlay quality, a sample wall is first made. After consultation and approval by the construction, planning, supervision, and construction organizations, large-scale paving is carried out according to the sample.
