Research On Construction Technology Of Exterior Insulation Mortar In GuangDong

Based on the building exterior insulation, Guangdong Province, the status quo, by exterior insulation and quality of factor analysis, the Guangdong Provincial Architectural exterior insulation for the construction process of the studyThe article by Guangdong Construction of exterior insulation status of research, found that the current building exterior insulation, Guangdong Province, there are design, materials, construction techniques, etc. affect the quality of external thermal insulation system. Raised the quality of the paper, according to factors, mainly from the construction process aspects of the Guangdong Province of polystyrene particles with the more common exterior insulation systems and inorganic mortar exterior insulation system for the analysis and experimental research, and proposed external wall insulation thoughtful decorative brick, it is a difficult construction process. By comparing the test and research, the use of engineering practice and put forward relevant technical control points.After a comparative test, draw relevant conclusions: must be prepared to primary treatment, to do tests on the operation of the workers, in strict accordance with the requirements of the construction process, outer insulation layer must be well hidden on each inspection, tiles anti-pull test should be cut to wipe the surface layer (not cut off the steel mesh).Polystyrene insulation through the pilot project, proposed to be the workers, process, material ratio, bolt layout, detail treatment and other aspects, and to develop relevant measures to tackle technical problems.Through the inorganic thermal insulation mortar pilot project, proposed to add pure crack flexible acrylic mortar, the mortar will crack soft mesh fabric to add a galvanized steel wire, galvanized wire with a long nail to net fixed in the wall of masonry, so as to solve the surface layer of thermal insulation and decorative brick mortar bonding layer off the common quality defects, ensure that the surface layer of decorative tile adhesive strength to meet the standards of quality acceptance criteria.Finally, the paper summarizes the use of insulation in Guangdong Province should pay attention to the system technical points: the construction should be carried out before a comprehensive test process, exterior tile uplift should be cut to wipe the surface layer of the surface, can not cut off steel mesh, must be strictly control the various construction process, good operation tests the skills of workers, cracking steel mesh recommended replacement galvanized steel mesh to increase the crack resistance, plastic anchors for enhancing the integrity of the insulation system have a stronger role. Add the appropriate inorganic mortar admixtures can improve the thermal insulation of the performance, to meet the bond strength and mechanical stability of the system under the premise must be stressed that the release of the stress to solve using flexible tile cracking, shedding problems. The article also raised outside the thermal insulation technology trends and prospects to promote awareness of the exterior wall of the new energy-saving technology to understand, thus speeding up the promotion and application of this new technology.
