Introduce the things you should pay attention to when attaching metal carved plates
The metal engraved board is a kind of material used for the insulation of the external wall. During the construction, it is necessary to pay attention to some problems in the use of the wall to avoid the situation of the bulging of the wall and affect the subsequent use.
First, inspect and treat the base layer, check the original exterior wall bricks, no cracking, no powder, no sand, no empty drum, no peeling, no lime bursting point and no old coating with poor adhesion. . According to the design drawing, the longitudinal and horizontal reference lines are bombarded on the wall by the ink line on the construction wall.
2. Dispense special bonding mortar according to the specified ratio, add special powdery binder to the appropriate water and mix it with electric mixer. Then start to paste. The diameter of each coating point is >150mm, and the number of square meters is not less. At 8 coat points.
Third, reinforced, strengthen the tensile strength and resistance of the soil, enhance the stability of the building structure, to change the quality of the soil. And leave a gap of 15mm between the board to adjust the installation error. When the decorative panel is installed, the deviation of the left and right, up and down should not exceed 1.5 mm.
Fourth, the installation of the internal anchors, the external anchors can not be too strong, so as not to cause damage to the board surface. The protection spreads, transfers or decomposes the concentrated stress well, preventing the soil from being damaged by external forces.
5. Paste well. After the position is determined, install the mechanical fasteners and fix the base layer with self-tapping screws. The anchors should be installed at a distance of 300~500mm from the middle of the straight side, 6-8 pieces per square meter. If necessary, add external pressure parts to adjust the height difference of the joints.
The metal engraved board pays attention to these five aspects when pasting, and there will be certain use guarantee for the subsequent use. Therefore, it is very important to say the professional level during construction. Some details of the use will be noted. Effect.
