Flexible connecting system for polyurethane heat preservation decorative sheets

Abstract

The invention relates to a flexible connecting system for polyurethane heat preservation decorative sheets. The base face of an outer wall is provided with the heat preservation decorative sheets which are assembled together, the heat preservation decorative sheets are stuck to the base face of the outer wall through bonding layers and are anchored on the outer wall through mechanical strengthening anchoring parts, and the sheet gap between the adjacent heat preservation decorative sheets is filled with sealing materials. The flexible connecting system is luxurious and attractive in appearance and has the decorative function and the heat preservation function, compared with traditional heat preservation and facing construction, the trouble of making a decorative layer after an external heat preservation system is constructed is saved, both the heat preservation function and the decorative function can be better ensured, operation procedures are simplified, labor intensity is lowered, a construction period is shortened, a keel does not need to be installed, and therefore materials and labor cost for installing the keel are saved. Maintaining cost is also low, if a PIR heat preservation and decoration integrated sheet is damaged by accident, only an old sheet needs to be detached, and a new sheet can be installed much simply and conveniently.

Description

technical field [0001] The invention relates to building heat preservation and decoration materials, in particular to exterior wall heat preservation materials and building exterior wall decoration materials, and in particular to a flexible connection system for existing building polyurethane heat preservation and decoration panels. Background technique [0002] Building energy conservation is an important part of the country's energy conservation work. For a long time, in the field of energy conservation and thermal insulation of building envelope structures in my country, many building exterior insulation technologies and exterior wall decoration technologies have been integrated, lacking scientific connection, especially in the compatibility of materials. There are still many problems in terms of compatibility, interlayer affinity, performance complementarity, construction complexity, construction quality uncertainty, construction coordination, etc., resulting in cracking, ...

[0002] Building energy conservation is an important part of the country's energy conservation work. For a long time, in the field of energy conservation and thermal insulation of building envelope structures in my country, many building exterior insulation technologies and exterior wall decoration technologies have been integrated, lacking scientific connection, especially in the compatibility of materials. There are still many problems in terms of compatibility, interlayer affinity, performance complementarity, construction complexity, construction quality uncertainty, construction coordination, etc., resulting in cracking, hollowing, or even falling off of the insulation layer. The phenomenon is not uncommon
