“Insulating Mould Cast-in-situ Concrete Grid Shear Wall Bearing System†passed the expert appraisal organized by the Beijing Municipal Construction Committee and the Planning Commission in November 2003. As a new type of building system, this product has received favorable comments from experts from the Ministry of Construction, the Central Government, and Beijing Research Institutions.
“Yili Thermal Insulated Bricklaying System†is a new energy-saving wall reforming system jointly developed by Beijing Yili Building Materials Co., Ltd. and the Beijing Municipal Office of Architectural Design Standardization jointly with the Civil Engineering College of Tsinghua University. Wang Haining, manager of Beijing Yili Building Materials Company’s technical department, told reporters that the system is a new type of building system integrating structure, heat preservation, heat insulation, sound insulation, and fire protection. With the advantages of excellent thermal performance, reasonable structure, avoiding thermal bridges, etc., it is a specification shaped exterior wall that can meet the insulation and heat insulation needs of houses in different regions. The interior walls of the masonry mold meet the insulation requirements of individual household heating walls, the sound insulation is 50db, and the fireproof performance is good. The advantages of using in ordinary buildings and steel structures are obvious.
"Yili insulation molding system" less flexible use of specifications, reduce design and construction block; lighter, easier to operate, to avoid the speeding up the construction of the demolition; brick and mortar insulation and water, conducive to concrete health; masonry and masonry wall Body form, continuous casting of concrete without support. The weight of the concrete grid wall is lighter, which reduces the base load. Cast-in-situ wall without the need for additional templates and insulation, reducing the process, reducing the overall cost. According to statistics, the average unit price of interior and exterior walls of masonry moulds is lower than that of concrete hollow brick walls and cast-in-place shear walls without external wall insulation by 11% and 23%, respectively.
The cast-in-place grid shear wall formed by the masonry mold has innovative structure, reasonable structure stress and good seismic performance. After the modified design proposal at the 8°C fortification area, it can build 9 floors, 28 meters high, and the number of layers. The height is higher than that of similar foreign structures, and the technical performance has reached the advanced level of the same kind in foreign countries, filling a gap in our architectural structure system.
At the same time, the polyphenyl granule concrete required for the production of heat-insulated masonry moulds can absorb a large amount of waste polyfoam, reduce costs, and also recover “white trashâ€, reducing pollution.
“Yili Thermal Insulated Bricklaying System†is a new system of building energy-saving wall renovation. It has novel construction, flexible use, and good thermal insulation effect. It has reached the advanced level of similar international systems. At the same time, it has a simple process and low overall cost. The need for new developments in building energy efficiency and wall reforms.
