A kind of external wall thermal insulation system

Abstract

The invention discloses an external thermal insulation system of an external wall. The system comprises a basic wall body. The external thermal insulation system further comprises a composite insulation board, wherein hooks are respectively arranged on the two edges of the composite insulation board, keels are connected with the basic wall body and distributed along the longitudinal direction in parallel, a distance between the adjacent keels corresponds to the width of the composite insulation board, connecting holes for the composite insulation board are formed in the keels, and the hooks on the two edges of the composite insulation board are respectively hooked onto the connecting holes for the composite insulation board in the adjacent keels, so that the composite insulation board is connected with the keels, and the basic wall body, the composite insulation board and the adjacent keels define and form a hollow inner cavity. The system is suitable for newly-built and existing buildings, has both thermal insulation performance and fireproof performance and good outdoor weather protection performance, and is convenient and quick to construct, convenient to maintain and suitable for both northern cold regions and southern rainy, damp and hot regions.

Description

technical field [0001] The invention relates to an external wall thermal insulation system suitable for newly built and existing buildings, which integrates thermal insulation, fire prevention, decoration and climate defense, in particular to a dry-hanging external wall thermal insulation system. Background technique [0002] Building energy consumption accounts for an increasing proportion of the whole society's energy consumption, making building energy conservation more and more important. External wall insulation technology is an important way to reduce building energy consumption. However, external wall insulation technology has encountered various problems and difficulties in past practice. [0003] Traditional inorganic thermal insulation materials have good fire resistance, but low thermal insulation performance; emerging organic thermal insulation materials, such as polystyrene and polyurethane, have superior performance, but there are fire hazards in construction a...

AI Technical Summary

Problems solved by technology

Polyurethane, EPS and other organic polymer materials may cause fire accidents in the construction preparation stage, construction wall stage and put into use stage; especially in the construction process, because the insulation board is exposed to the air and lacks protective measures, fire safety management Not in place and other reasons, it is easy to cause a major fire accident

In addition, these systems have disadvantages such as complicated procedures, long cycle times, and construction operations that are easily affected by the environment, and are prone to problems such as cracking, bulging, layering, blooming, falling off, and leakage during use.
