Nowadays, decoration requires a beautiful and atmospheric appearance, as well as functional requirements. The integrated insulation and decoration board has the basic function of thermal insulation and fire prevention, and adds the function of decorative aesthetics, which is more in line with the contemporary functional needs of insulation boards. In terms of integrated insulation and decoration panels, it is indispensable in daily construction. Taking the drywall stone curtain wall as an example, the construction process of the integrated insulation and decoration board embedded in the external wall is introduced in detail.

1. Process flow: Separate the measurement and laying out stone keel at the grassroots level, install the rock wool board together with the cut rock wool board, and fix the rock wool board with plastic expansion bolts to cover the dry hanging stones, and conduct special inspections on the curtain wall.

2. Measure the stone keel according to the design requirements of the building's exterior wall, and then install the stone keel.

3. Rock wool board cutting device: Cut the rock wool board according to the spacing of the stone keel, and then pass it horizontally from bottom to top. Afterwards, the fixed plates are vertically staggered from the corners of the wall. Interlocking of yin-yang angle rock cotton board. Rock wool board cannot be spliced in the corners of doors and windows. At this point, a whole rock wool board should be used to cut a cut perpendicular to the board surface, and the same insulation board should be used to fix the corners. The upper and lower plates should be arranged in a staggered manner, with a distance of approximately half the length of the plate. The width of the narrow rock wool board used for filling should not be less than 150 millimeters.

4. Rock wool board fixation: The rock wool board anchor is installed on the structural wall with a depth of not less than 50 millimeters. Usually, 8 * 120mm plastic expansion bolts are used for anchoring. Drill holes on the outer wall with an electric hammer. The hole diameter is 12mm and the hole depth is 120mm (including the thickness of the insulation board), so the rock wool board is tightly bonded to the outer wall. Binding. After fastening, the anchoring point should be located 1-2mm below the surface of the rock wool board.

5. Anchor point arrangement: The anchor point is set between the rock wool board and the horizontal joint. The installation distance of anchor bolts is 300mm in the longitudinal direction, 400mm in the transverse direction, and 200mm in the plum blossom shape. Compliant with design and relevant standards.

6. Rainproof and moisture-proof measures: Before applying oil to the top of the rock wool board, it should be covered with plastic cloth to prevent rainwater from seeping into the rock wool board. Single anchor test, the standard value of tensile strength is greater than or equal to 0.3KN. During the construction period, various professional work should be closely coordinated and procedures should be arranged reasonably. Reverse operation is strictly prohibited. The integrated insulation and decoration board should be protected from damage caused by heavy objects hitting the wall. Once found, it should be repaired promptly.

7. Inter floor fire protection: Place inter floor fire barriers along the perimeter of the walls at the height of each floor project. This is because there is a 200mm gap between the inner surfaces of the exterior wall stones. Its main purpose is to prevent the flame from spreading from the gap to the upper layer after the flame, thus providing an interlayer fire barrier. The material is 1.2mm galvanized steel plate and 50mm fireproof insulation mineral wool board. One end of the galvanized steel plate is fixed to the outer wall with a nail. The nail spacing is 500mm, and the other end is fixed on the horizontal angle steel keel.
