Description

Technical Field

[0001] The utility model relates to the field of thermal insulation walls, and more specifically to a lightweight steel wire mesh composite thermal insulation wall structure. Background Art

[0002] With the development of the construction industry in today's society, the application of self-insulating walls is becoming more and more extensive, and its performance requirements are becoming higher and higher. The wall self-insulation system refers to a building wall insulation and heat insulation system that uses energy-saving wall materials and supporting special mortars according to a certain building structure to make the physical performance indicators such as thermal performance meet the corresponding standards. The application of this system can make construction convenient, improve safety performance, extend the life of the wall, and reduce construction costs. However, most of the current insulation walls have many problems, such as poor fire resistance, easy cracking and falling of the internal wall materials, poor durability, poor rain resistance, and easy rainwater leakage. These problems will have a great impact on the safety performance of the insulation wall.

[0003] The utility model with authorization announcement number CN206298984U discloses an air-tight steel wire mesh composite insulation wall, comprising a non-load-bearing reinforced light concrete wall, an air-tight layer, an insulation layer, a steel wire mesh layer, a fire protection layer and anchor bars; the air-tight layer is arranged inside the non-load-bearing reinforced light concrete wall, the insulation layer and the fire protection layer are arranged outside the non-load-bearing reinforced light concrete wall in sequence, the steel wire mesh layer is arranged between the non-load-bearing reinforced light concrete wall, the insulation layer and the fire protection layer, and the anchor bars are arranged on the left and right sides of the non-load-bearing reinforced light concrete wall. The utility model has an air-tight layer inside the wall, which can not only reduce its own weight, but also has better insulation and fireproof performance than ordinary insulation walls; a steel wire mesh layer is arranged between the walls, so that the wall connection is stable and not easy to split; it has good insulation effect, strong fireproof performance, safety and environmental protection, good durability and low cost.

[0004] In the above disclosed structure, an air layer is set inside the wall, but the spacing affects the thermal insulation effect and also reduces the structural strength of the wall. The lack of internal connection reinforcement structure affects the safety and stability of use, and needs to be improved. Utility Model Content
