Description

Class A fireproof insulation decoration integrated hanging board for building exterior wall

technical field

The utility model relates to the fields of fire prevention, heat preservation and decoration of building exterior walls, namely a class A fireproof heat preservation decoration integrated hanging board for building exterior walls.

Background technique

In the existing technology, with the deepening of energy-saving work in residential construction in my country and the continuous improvement of energy-saving standards, the reform of building walls and the development of energy-saving technology for walls are an important link in building energy-saving technology. The development of external wall insulation technology and energy-saving materials is the main way to achieve building energy conservation. Most of the existing energy-saving methods for walls are to use external insulation materials for external wall insulation. Due to the unsatisfactory flame retardant effect of some external wall insulation materials, there are some fire hazards. Therefore, in 2009, the Ministry of Housing and Urban-Rural Development of the Ministry of Public Security promulgated Gongtongzi [2009] No. 46 document, about printing and distributing the "Interim Regulations on Fire Protection of Civil Building Exterior Wall Thermal Insulation System and Exterior Wall Decoration". In 2010, Jilin Provincial Department of Housing and Urban-Rural Development and Jilin Provincial Bureau of Quality and Technical Supervision jointly issued "Jilin Province Civil Building External Thermal Engineering Fire Protection Technical Regulations" DB22496-2010. The above two documents put forward specific and clear requirements for the fire protection structure of residential buildings and public buildings based on the function of the building and the height of the building to the specific situation of the external insulation engineering of new and renovated civil buildings in my country and Jilin Province at this stage.

Building exterior wall insulation often adopts pasting benzene board, laying mesh, plastering cement surface, and brushing paint. The disadvantage is that most of the benzene boards are B-class fireproof materials. Even if the material of the A-class fireproof benzene boards is also a hot-melt material, the fireproof effect is not ideal.

Building exterior wall insulation also adopts A-class fire-proof insulation materials on the wall and curtain wall panels installed with large-scale overall framework. The disadvantage is that the large-scale overall framework is bulky and has many raw materials for steel structures. If there is a gap, once there is a fire, there will be a fire phenomenon, which will lose the flame retardant effect and affect the thermal insulation performance.
