Firstly, the colors of ceramic tiles are selected and classified by colorimetry. The tiles installed on the same side have the same color. According to the design size and drawing requirements, a special mold is fixed on the bench drill to punch the stone. Then brush unsaturated resin glue on the back of the stone. Write the number on the tile before the first glue brushing, and clean up the floating ash and impurities on the tile.
2, metope frame pay-off and installation skeleton
First, clean the structural surface of dry-hung tiles. Then stretch the position of the skeleton to the main structure. Pay-off according to the axis and elevation points. Use theodolite to control verticality, use level to measure horizontal line and mark it on the wall. Generally, the position of the stud will pop up first to determine the anchorage point of the stud. After the vertical bars are arranged, the position of the horizontal bars will bounce on the vertical bars. Skeleton construction focuses on the welding quality and deformation between the main keel and the embedded parts of the wall, and the construction method without embedded parts, and organizes the owner, supervisor and Pudong New Area Quality Supervision Station to conduct hidden acceptance. Quality control points of skeleton installation: elastic line positions of longitudinal and transverse keels; Whether the vertical keels are in the same plane.
Installing tiles
Drilling, slotting and anchoring. First, slot and drill holes at both ends of the slate. The hole center is 80- 100 mm away from the plate end, and the hole depth is 20-25mm. Then drill a hole with a diameter of 8- 10 mm at the corresponding position relative to the marble slab wall. One end of the stainless steel expansion bolt is inserted into the hole and fixed, and the other end is hung with an anchor.
4. Install the ceramic tile bottom plate.
First, install the bottom tile according to the position of the stainless steel anchor fixed on the wall. Align the holes and grooves of the tiles with the footbolts, and then adjust the flatness, verticality and gap of the tiles with the rectangular bolt holes on the footbolts. Then the tiles are fixed firmly with anchors, and the anchors are fixed with glue.
5. Install the uplink board.
First, inject the embedded glue into the bolt holes of the next row of plates, wipe off the residual glue, and then install the tiles in the last row in place according to the method of installing the bottom plate. Check the installation quality and repair it after it meets the design and specification requirements.
6, sealant caulking
After the tile hanging construction is completed, clean the surface and remove the dust in the gap. Firstly, the foam plastic strip with a diameter of 8- 10 mm is used. The new technology requires new technical requirements, which requires our construction personnel to keep learning and practicing, so that practice makes perfect.
