It can bear the expansion better, shorten the deformation caused by the external natural conditions, and eliminate the deformation stress of temperature difference uniformly, so as to effectively avoid the occurrence of cracks. For example, the outer surface faces the brick, but the wire diameter and hole spacing of the wire mesh shall be determined experimentally, and the short side facing the brick shall be at least two holes. Galvanised steel mesh against corrosion (rust) shall be suitable for screening.
Single net structure and traditional steel wire frame polystyrene board external insulation system for cement mortar leveling have great irrationality (large load, easy to crack), and the external is subject to positive and negative wind pressure, thermal expansion and contraction, shrinkage and humidity should use expansion, small and light mortar and short crisp rate to manufacture aircraft, and use double network structure to end the activity process. Make changes to reduce load and increase crack resistance.
Quality control standard of travel isolation system. It is necessary to test the insulation quality of the wall due to the original data, the difference of sampling and inspection, the construction conditions and many other chaotic factors. In order to improve the quality of wall insulation, the quality control speed of the insulation system is improved. Carry out mathematical calculation under normal production and construction conditions. Select a method to find the same value and standard deviation of heat transfer coefficient of multiple heat insulation data sets.
