The fiberglass cloth is firmly bonded to the base layer, and after drying, it is mixed with cement (1kg: 2.5kg) with 923 glue to form a glue putty, which is scraped twice to survive. Spray coating construction is carried out after the moisture content of the surface layer reaches the requirement (not more than 1%). The quality standard guarantees that the specifications, quality and performance indicators of the project insulation board must meet the requirements. The insulation board and the base body must be supported, hung and bonded firmly, without defects such as delamination and cracks. The setting of the support and the hanging point must meet the requirements. The surface of the basic project: the board and the board are closely arranged, the line angle is straight and square, and there is no trace of the joint, and the surface is smooth, clean and free of crease. The expansion joints are set as required, the seam width and depth are uniform, and the rubber strips are smooth and straight. The construction of the nodes and the anchoring of the rules are all in compliance with the regulations.
The organization of the labor organization should be divided into groups according to the process requirements, and the construction should be carried out from the bottom to the top to ensure the interval between the processes. Insulation board: 35 people per operation group, 12 workers for transportation and feeding; 23 people installed. Surface layer: 35 people per operation group, 12 small workers transported and supplied materials; 23 people plastered and laid the net. 1.3.7 Finished product protection 1) It is strictly forbidden to damage the wall surface during the construction of the hanging basket shelf, and the side of the shelf is used as the fulcrum of the rubber pad. Walls and pipes (water, electricity, ventilation, air conditioning, equipment) should be made in advance to prevent damage to the finished insulation board. Take measures to prevent quick drying, water rushing, impact, vibration and extrusion before the 923 mortar is hardened to ensure its sufficient strength. After the insulation board enters the site, it should be kept safely. Avoid damage during stacking, transportation and installation, and damage the board.
Quality problems that should be noted: 1) The cleaning of the base layer is not clean: it will directly affect the adhesion, and should be carefully cleaned to expose the base layer and water the wall in advance. 2) The door window, the top of the insulation board, the edge of the insulation, etc. should be carefully treated with water resistance. The four corners of the door window are reinforced with a mesh cloth to prevent cracks. 3) Anchorage should meet the requirements: L-type brackets are fixed with nails. If they are not nailed at one time, they must be re-doed or changed to use holes and install expansion bolts. The pendant is made of plastic bulge. After tightening, use the pliers to do the pull test. If it is loose, it must be redone. 4) 923 mortar mixing materials should meet the requirements, the ratio should be accurate, calculate the materials in advance for each use, it is strictly prohibited to add water during use, it is strictly prohibited to use outdated ash. 5) When the 923 mortar does not reach the strength, it is strictly forbidden to carry out the post-order work, such as: filling the rubber strip, punching the hole at the pendant, and attaching the fiberglass cloth. 6) Cutting of the insulation board must use cutting machine and steel data, and it is strictly forbidden to cut or smash.
