In recent years, people have paid more and more attention to the beauty of building construction, not only in high-rise buildings, but also in places where people live. Therefore, the decorative lines of the external walls gradually emerged, because the external walls of the decorative lines are more foreign, more three-dimensional, and they feel more noble. Then, Xiaobian will introduce the steps of the exterior wall moldings and the advantages of the exterior wall moldings. External wall molding installation steps First, grassroots cleanup 1. Clean up the remaining floating ash on the concrete wall surface, release agent oil and other debris and plastering empty parts. 2. Remove concrete blocks, inclusions, empty drums, etc., which have been split at the wall joints, and repair them again. The window sill picks up the slope according to 2% with a cement mortar, and the outer walls are densely packed with various openings. 3. It is required that the deviation of the flatness of the surface of the adhered polystyrene board should not exceed 5mm. When out-of-tolerance, the protruding wall surface should be ground, and the concave part should be repaired (When the thickness is over 6mm, the plaster must be used for 1:3. When the thickness is less than 6mm, the thermal insulation construction unit will use the polymer cement mortar to make up for it; to ensure that the flatness of the entire wall surface is within 5mm, the yin and yang angles are square and up and down. Second, the preparation of mortar 1. The mortar used for construction is divided into special adhesive mortar and surface layer polymer anti-cracking mortar. 2. When using the hand-held electric mixer to stir the mixture during construction, the mass ratio of cementitious mortar mixed (or manually stirred) is: water: mortar = 1:5, stirring while adding water; stirring time ≥ 5min, stirring must be adequate and uniform, moderate consistency , and have a certain viscosity. 3. After the mortar has been prepared, it shall be allowed to stand for 5 minutes, and the mixture shall be stirred again before use. The mortar prepared shall be used within 1 hour. 4. According to the construction drawings, the positioning line (middle line or edge line) will pop up at the site where the EPS components are to be installed. Third, according to the size of the drawings to install cutting EPS components. The corners should be cut into 45° angles. The EPS components are all standard sizes. The width of the joints should be taken into account when cutting. Fourth, the EPS component paste: EPS component adhesive using high-quality adhesive mortar, using a thin layer full stick method paste, squeeze the EPS component to make the mortar overflow from the surrounding, the joint width is not more than 3mm. Adhesive joints should be adhered with adhesive hooks, full of gray joints, and keep the surface of the EPS member tidy. Actual operation, the general wall surface roughness is difficult to meet the construction requirements, you can use the same method as sticking wall tiles on the upper and lower edge of the line marked with adhesive mortar, the middle of the selection of beating, and then pressed at the paste site to force the plastic The slurry overflowed. However, the bond strength is worse. 5. For larger EPS lines, it is required to set the support for temporary fixing during installation, or to set a nail to hold the line at the bottom of the line to prevent slippage. 6. When assembling, if splicing is required, the assembling dimensions and angle should be measured in advance, and pre-assembled in the flat place with a gap of not more than 3mm. With high-quality adhesive mortar as the bonding material, the consistency of the mortar can be slightly larger, using a thin layer full-stick method. When splicing, it requires a slight, even forceful squeezing and hammering so that the sliver seam meets the requirements. Seven, splicing finished mortar application gray knife hook flat, so that the EPS component into one. After drying, if there is excess adhesive mortar left on the joints of the EPS line, it can be sanded. Eight, patchwork processing When the width of the EPS exterior decorative line bonding seam is not more than 3mm, the sanding of the joints is performed on the next day after installation, and a 100mm wide glass fiber mesh cloth is used with a high-quality top coat mortar, and the thickness is less than 2mm; the bonding seam is large At 3mm, the inside of the seam was filled with thin polyphenylene sheets, and then reinforced with a high-quality top coat mortar and a 100mm wide glass fiber mesh cloth. After drying, if there is excess mortar left at the joints, the processing method is the same as above. Nine, finished construction eps lines, external walls eps lines, eps decorative lines to pay attention to product protection, is strictly prohibited stomping, heavy impact. Advantages of decorative wall lines First, light weight. Taking a 50×50 cm decorative line as an example, the weight is about 1/6 of the GRC decorative line. One can move and construct it at will. Second, paste firmly. The security of the decoration line (piece) is very important, especially the requirement of the quality lifetime system. If you only emphasize on beautification and do not pay attention to safety, it will bring great risks. The EPS trim line is not only light weight, but also has a strong bond with the base wall. It mainly uses polymer mortar for bonding, while polymer mortar is made by adding organic glue to inorganic materials and cement mortar. It not only has long service life, but also has firm bonding, and it already has national standards and specifications, and in a large amount The application in the project proves to be feasible and is safe and reliable. It eliminates the quality accidents caused by the use of anchor bolts to fix the hidden dangers of construction and the hidden dangers of anchor corrosion. Third, the shape of random processing. Due to the automatic cutting of the computer design styling, the line (piece) style is arbitrary, the processing is simple, and the installation is convenient. 4. It is better to work with the EPS external insulation wall surface. Today, with the rapid development of building energy conservation, the external insulation system of the EPS board exterior wall is the only system of choice, but the architects are worried about whether it will affect the realization of the facade effect. EPS The decorative line completely dispels the architects' concerns, not only that, but also enables the architect to design the shape as he likes, and to form a perfect match with the external insulation wall. Fifth, easy to install. Using a special bonding material and method, one can install the construction, especially for the larger body components, and just bond and install. Six, decorative lines (pieces) smooth, beautiful, seamless between the lines. Because the gap repair material was used between the two lines, the gap disappeared. No cracks will appear in later use Seven, EPS EPS decorative line (piece) the biggest advantage is that she completely solved the external wall insulation cold and hot bridge problems. Editor's summary: The advantages of the installation of exterior wall moldings and the advantages of exterior wall moldings are introduced here. We hope to help everyone.
