Fabrication method for external thermal insulation system of outer wall

Abstract

The invention relates to a fabrication method for external thermal insulation system of outer walls, in particular to a framework structure outer wall external thermal insulation and decorative surface combined construction method; the invention is characterized in that the external thermal insulation system for outer wall of mechanical anchoring EPS steel net board and the external thermal insulation system for outer wall of EPS board thin plaster are effectively compounded, two different external thermal insulation systems for outer walls are combined on one wall on the wall taking outer decorative face of framework structure as coating; the external thermal insulation system for the outer walls of the invention has light dead weight and reduced load, and the decorative mortar has good adhesiveness, low water absorptivity and excellent waterproof effect as well as excellent air permeability and low crack sensitivity; in addition, the invention can meet the requirements of buildings for the physical function of the materials, such as the protection of wall surface weather resistance and the like. Simultaneously, masonry does not need plastering above two storeys, thus saving labour, time and materials.

Description

Technical field: [0001] The invention relates to an external thermal insulation system for building exterior walls, in particular to a method for manufacturing the external thermal insulation system for external walls of buildings with frame structures. Background technique: [0002] At present, most of the external wall insulation systems with paint as the exterior surface are EPS board thin plastering systems. Even if the insulation layer of the first floor of the building is made of reinforced mesh and then pasted with facing bricks, it is often damaged under the action of external impact; it not only affects the aesthetics of the building, but also causes the penetration of rain, snow and water vapor, which will cause long-term protection. The layer is empty, falls off and endangers the safety and stability of the entire insulation system. This phenomenon appears in the construction projects and occurs from time to time. In order to solve this problem, most of them use...

AI Technical Summary

Problems solved by technology

This production method first needs to prefabricate rigid polyurethane composite panels, which not only increases the construction process of the external wall insulation system and increases the production and processing costs of thermal insulation materials, but also cannot solve the common problems of hollowing and falling off of the protective layer on the first floor of buildings. question

In addition, this production method does not propose a more suitable and detailed construction method for the external thermal insulation system on the first floor and above the second floor of the building's external wall. If it is bonded to the external wall, there will be safety hazards caused by the external thermal insulation system of the external wall due to its heavy weight, and the thermal insulation performance is also difficult to guarantee.
