Installation Technology of Thermal Insulation Decorative Board
Installation method:
Basic wall solution - layout design of construction setting out - special adhesive - Application of adhesive cement mortar - board laying - sticking and installation - reinforcement anchoring - joint joint solution - surface cleaning self inspection civilized construction and engineering acceptance. The details are as follows:
1. Basic wall solution: when sticking extruded polystyrene board, the dirt such as film remover, concrete sediment, and Panax ash soil on the base wall should be clean and tidy, so as to fully ensure the penetration of plastering mortar and basic moisture penetration, and improve the bonding strength of cement mortar.
2. Layout design of construction setting out: hang the isoline according to the building's yang angle line or release the equidistant line with theodolite as the reference point, operate the basis of the vertical of the positive angle line and the lower part. In addition, the vertical line and horizontal line are springed from the bottom to the upper layers to control the flatness and levelness of the integrated board laying of the thermal insulation and decoration.
3. Special binder: the slurry is stirred by hand-held electric mixer for about 5 minutes until the consistency is moderate. Ensure that the epoxy mortar has the corresponding viscosity.
4. Apply adhesive cement mortar: when sticking the insulation decorative board, point frame method is used. It is to apply 80-100mm wide and 10mm thick plastering mortar near the polystyrene insulation board, and leave a 50mm exhaust stable channel nearby. After that, the plastering mortar cake with diameter of 100mm and thickness of 100mm shall be plastered in the middle, and the distance between them is about 100mm. The total area of plastering mortar shall not be less than the total surface of each polystyrene insulation board 50% of the product.
5. Plate arrangement: arrange and install in horizontal order, vertical up and down, and Huakang of Yangjiao line.
6. Installation of adhesive: during sticking, the plastering mortar shall be evenly extruded into an integral board of thermal insulation and decoration, so that the plastering mortar is in close contact with the wall, and it is flush with the adjacent thermal insulation decorative board. When the plastering mortar is extruded, it is scraped with a blade to ensure the bonding is dense. Check the flatness and flatness with 2m ruler and supporting line at any time. Pay attention to the cleaning of the plastering mortar spilled out of the board to make sure that there is no "bump head" between the board and the board Grey ", the joint is reasonable.
7. Reinforcement anchoring: after the thermal insulation decoration board is pasted, the mechanical external wall rock wool board (expanding pipe screw) shall be used to fix the extruded polystyrene board according to the design regulations. When the impact drill is used to drill holes in the middle of the joint and the groove of the two integrated thermal insulation and decoration boards, the aperture is determined according to the diameter of the rock wool board (expanding screw) of the outer wall. The length of the rock wool board (expanding pipe screw) of the outer wall is determined by the thickness of the insulation and decoration integrated board The depth of fixed and deep wall shall not be lower than the design requirements. The nail head and disk of the rock wool board (expanding screw) of the outer wall shall be in the groove in the middle of the joint, and shall not exceed the surface of the thermal insulation decorative board, and hide in the middle of the integrated board of thermal insulation decoration, so that the decoration effect of the integrated board of thermal insulation decoration is not affected. Then, it can be well combined with the cement mortar bonding with the integrated board of thermal insulation and decoration, which is firmly fixed, and the stability can be improved, and the insulation decoration can be realized. The size of the insulation and decoration integrated board needs to be added with the external wall rock wool board (expansion screw).
8. Joint joint solution: after the surface is cleaned and tidy with cleaning agent (whether to use the American pattern paper tape according to the actual situation), the material such as pointing agent shall be injected into the gap between the integrated board of thermal insulation and decoration. The injection agent shall be careful to control the construction thickness of the joint agent in combination with the design drawings, and shall be full, There should be no air gap or bubble, the ash knife should move at a uniform speed along the joint, and the strength of the squeeze forming pointing agent should be even; the pointing agent is too thin.
