Professional rock wool insulation board, well-known manufacturer of rock wool insulation board Rock wool exterior insulation construction method 2 Features Rockwool external insulation system has good thermal insulation performance, crack resistance, fire performance and durability. At the same time, rock wool board and base wall adopt effective fixing measures, wind load Excellent performance; using rock wool board anchoring technology, the construction speed is fast and the process is simple, the construction period can be shortened, the labor cost and labor intensity of the project can be reduced, and the construction cost can be reduced. Green and environmentally friendly, the cost is moderate, it is a kind of external thermal insulation technology worth promoting. 3 Scope This method is applicable to the exterior insulation project of the exterior wall decoration surface of the building as the paint finish. The outer wall can be concrete wall and various masonry walls, and it is also suitable for energy-saving renovation projects of various existing buildings. 4 Process principle Rockwool external wall thermal insulation system is mainly composed of rock wool insulation material. The anchors such as plastic expansion bolts are combined with hot-dip galvanized steel wire mesh to fix rock wool board. The surface of hot-dip galvanized steel wire mesh and rock wool board surface is added. The gasket has a certain distance between the hot-dip galvanized steel wire mesh and the rock wool board, which is beneficial to the plastering treatment on the surface of the rock wool board; after the rock wool board is fixed, the surface of the rock wool board is treated with an interface to enhance the rock. The waterproofness and surface strength of the cotton board, and effectively solve the problem of bonding the rock wool board and the polystyrene particle screed layer. The surface layer of the sizing powder polystyrene granules is leveled, and the surface load of the rock wool board is not too large, and at the same time, it has the characteristics of light weight, flame retardant fireproof, crack prevention and cost reduction. The anti-cracking protective layer is made of anti-cracking mortar composite coated plastic alkali-resistant glass fiber mesh to form a crack-resistant protective layer, which has good crack resistance, and the brush can effectively prevent the elastic liquid from entering the liquid water, and the facing layer is flexible and water-resistant. Putty, brushed elastic coating, the basic structure is shown in Table 1. Basic structure of rock wool board exterior insulation system. Glass rock wool insulation construction: 1 After the glass wool material enters the site, it must have the factory certificate and inspection report form. After entering the site, it will be re-tested and qualified for installation and construction. 2 After the keel is completed, the fire-resistant glass wool insulation layer is laid in the keel interlayer. The outer wall of the glass wool is composed of three parts: the functional wall structure layer, the insulation layer and the veneer layer. The main technical key is: the insulation layer and the structural layer are connected. 3 Insulation layer and structural layer connection method: The connection mode between insulation layer and structural layer is fixed by 8X120 expansion bolt scheme, 6 expansion bolts per glass wool board, thickness of glass wool board 80, plaster layer 15 to ensure expansion bolt Into the structural layer is greater than 25, mark on the drill bit to ensure that the thickness of the glass wool board does not appear negative, the construction method is convenient, fireproof, safe and reliable, and also has good durability. (See Figure 1) 4 Glass wool board installation: 4.1 Glass wool board row board requirements: according to the standard whole sheet (size: 1200X600), from the bottom to the top in the horizontal direction, 1/2 board length interlaced . Vertically staggered the fixed plates from the corners of the wall to ensure that the corners are straight and vertical. The glass wool boards at the yin and yang corners are interlocked and interlocked. The glass wool at the four corners of the door and window openings shall not be spliced. The whole glass wool board shall be used to cut the forming cuts perpendicular to the board surface, and the same insulation board shall be applied and fixed at the corners of the wall surface. 4.2 The glass wool board is designed and laid before use. Calculate the size and cut the blank. The linear error of the trimming edge should be less than 5mm, the seam should be no more than 2mmm, and the gap between the board and the board should be bonded with special tape. 4.3 Glass wool board laying should be connected from top to bottom, and the glass wool board should be laid in order. When encountering the door and window opening, it should meet the requirements of the relevant atlas. 4.4 Board anchoring and surface treatment (1) Anchoring: The depth of the installation wall of the anchor plate installed in the insulation board is not less than 25mm. The Φ8X120mm anchor screw is used for anchoring. The electric hammer is used to drill the outer wall with a hole diameter of 10mm. The hole depth is 120-130mm (including the thickness of the insulation board). The plastic expansion bolt is installed and sturdy, so that the glass wool board is close to the outer wall. Combine. After the anchoring point is tightened, it should be lower than the surface of the glass wool board by 1~2mm. The arrangement of anchor points: anchor points are set in the four corners of the glass wool board and in the middle of the horizontal joint. (2) The longitudinal spacing of the anchor bolts is 300mm, the lateral spacing is 400mm, the plum blossoms are arranged, and the corners of the base wall are encrypted to a spacing of 200mm, which meets the requirements of design and related standards. 4.5 System waterproofing and special parts treatment (1) When the window door opening is encountered, the length and width of the board are determined according to the wall part and the length and width of the glass board. (2) Waterproof and moisture proof: Each piece of glass wool board is packed in a plastic bag. Check whether the plastic bag is damaged before installation. If there is damage, add a small plastic bag; before the top of the glass wool board is finished, the stone is not hanged before the glue is applied. Cover with plastic cloth to prevent rain from leaking inside the glass wool board; the bare glass wool board at the corner of the glass wool board is firmly adhered to the aluminum foil strip of the same material as the surface layer; The ketone sealant must be tight. (3) Prevent the occurrence of thermal bridges. The pre-embedded iron pieces are welded to the main keel on each layer of the structure. The embedded parts are thermal bridges, and 15 thick silicate cement mortar partition heat bridges are laid on the inner side of each side beam. 4.6 Check the anchoring point, flatness and bonding quality between the connected panels after the fireproof non-combustible glass wool is finished.
