External insulating system for thinly plastered external wall of extruded polystyrene board

Abstract

The invention relates to an external insulating system for a thinly plastered external wall of an extruded polystyrene board, which comprises a wall structure layer. The external insulating system is characterized in that the wall structure layer consists of extruded board adhesive cement, the extruded polystyrene board, extruded board anti-cracking mortar, a hot galvanizing steel mesh, a tray anchor bolt, ceramic tile binder and a ceramic tile in turn, the extruded board adhesive cement and the extruded polystyrene board are hard boards manufactured by the continuous extruding-foaming-shaping technology and provided with closed hole honeycomb structures; and an extruded board interface agent is coated on two surfaces of the boards. The external insulating system has the advantages that the problem that the extruded polystyrene board with two smooth surfaces is stuck with other insulating building materials is solved, and the external insulating system has excellent insulating function; the energy consumption of heating and cooling for living is greatly reduced; no clear thermal bridge exists; the phenomena of dewing and freezing at lower temperature in winter are avoided; the water-proof and damp-proof functions of the wall are increased so as to effectively protect the building main body structure; the system has good living comfort level and does not affect the actual using area of the house; the application range is broad; and the system is applied to various new and old buildings.

Description

technical field [0001] The invention relates to an external thermal insulation system of an extruded polystyrene board thinly plastered external wall. Background technique [0002] With the in-depth implementation of the national energy-saving policy and the continuous improvement of people's requirements for the comfort of the indoor thermal environment, the external wall insulation system has been widely regarded as one of the most effective building energy-saving measures. powerful means. The wall is the main heat exchange carrier in the building, so the thermal insulation of the wall can play a pivotal role in the external enclosure structure and building energy saving. At present, the energy-saving work in residential construction in our country continues to deepen, and the energy-saving standards continue to improve. Many new energy-saving technologies and materials have been introduced and developed, and they are vigorously promoted and used in residential buildings....
