Before the construction of the metal engraved sheet, the model shall be confirmed by the design, supervision and other units before construction. The following small series will introduce you to the basic situation of metal carved plates:

Check and deal with the base of the metal engraved board, check the original exterior wall brick, no cracking (such as cracking filled with hard filling material), no powder, no sand, no empty drum (such as empty drum should be knocked out) No peeling, no lime cracking point and no old coating with poor adhesion. The longitudinal and lateral reference lines are ejected on the wall by the ink line on the construction wall according to the design.

Dispense special bonding mortar according to the specified ratio, add special powdery binder to the appropriate water and mix it evenly with electric mixer. Then start to paste the metal engraved board. The diameter of each coating point is >150mm, and the number of square meters is not less. At 8 coating points. A gap of 15 mm is left between the plate to adjust the installation error. When the decorative panel is installed, the deviation of the left and right, up and down should not exceed 1.5mm.

The metal carved plate is pasted. After the position is determined, mechanical fasteners should be installed and fixed on 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. Install the inner anchor and the outer anchor without excessive force to avoid damage to the board surface.

The use of metal engraved panels is very wide. Today, we will introduce you to the anti-sliding stability of the protective layer and the knowledge of the materials.

1. Reinforce, strengthen the tensile strength and deformation resistance of the soil, and enhance the stability of the building structure to improve the soil quality.

2, closed, with other materials, forming an impervious barrier in the soil layer, the application of this aspect is mainly used for road resurfacing, repair and so on.

3. Protection effectively spreads, transfers or decomposes concentrated stress, preventing the soil from being damaged by external forces.

4. Filtration When water flows from the fine-grained soil layer into the coarse-grained soil layer, it uses the good gas permeability and water permeability of the needle-punched metal-engraved board to pass the water and effectively intercept the soil particles, fine sand, small stone, etc. Maintain the stability of water and soil engineering.
