Description
Technical Field
The utility model relates to a building external wall heat preservation system.
Background
The building outer wall external heat preservation system is not only suitable for heating buildings in areas needing heat preservation in winter in the north, but also suitable for air-conditioning buildings in areas needing heat insulation in summer in the south; meanwhile, the method is suitable for newly-built buildings and energy-saving reconstruction (old house reconstruction) of the existing buildings. Many existing buildings in China today have poor heat insulation effect of the outer wall, high energy consumption, dew condensation and mildew of the indoor wall in winter and poor living environment. If the energy-saving reconstruction is carried out by adopting the external heat preservation of the outer wall, the normal life and work of residents in a room are not affected. The building outer wall external heat insulation system is composed of a heat insulation layer, a protective layer and fixing materials, and is a non-bearing heat insulation structure arranged on the outer surface of the building outer wall, wherein the fixing materials comprise an adhesive, anchoring parts and the like. The existing building outer wall outer heat preservation system has a wider popularization range and comprises an EPS board thin plastering outer wall outer heat preservation system, cast-in-place concrete EPS outer wall outer heat preservation, cast-in-place steel wire frame EPS outer wall outer heat preservation, mechanical fixing EPS outer wall outer heat preservation and the like. The EPS board thin plastering external wall external heat insulation system has the most wide application such as high energy saving efficiency, capability of eliminating wall temperature gradient, no thermal bridge and the like.
The main heat insulation material of the EPS board thin plastering external wall external heat insulation system is an EPS board (expandable polystyrene board), and the common fixing mode is that mortar bonding and anchor bolt fixing are used in combination; however, because the EPS board is inflammable, electric welding, open fire and the like can cause fire, too many fire events caused by building heat preservation occur in recent years, and the fireproof performance of the heat preservation material attracts great attention in various industries. In order to improve the fireproof capacity of the building exterior wall external heat insulation system, the fireproof requirements of the civil building exterior wall heat insulation system comprise: the combustion performance of the heat insulation material of the building with the height of more than or equal to 100m is A level; the fire performance of the heat insulation material of the building with the height of more than or equal to 60m and less than 100m is not lower than B2 grade. When the B2-level heat insulation material is adopted, each layer is provided with a horizontal fireproof isolation belt. However, due to the inflammable nature of the EPS plate, when a large-area fire occurs, the combustion of the EPS plate located at the lower portion may further ignite the EPS plate located above, resulting in continuous combustion and increased difficulty in fire extinguishment. For example, the EPS board thin plastering insulation system for the alpine region disclosed by CN210177713U comprises a base layer wall, an EPS board, an adhesive layer, a thin plastering reinforcing protective layer and a finish layer are sequentially and fixedly connected from the base layer wall to the outside, and the EPS board thin plastering insulation system for the alpine region disclosed by CN210177713U can well adapt to the alpine working environment, effectively avoids the influence of climatic conditions such as altitude hypoxia and freezing, greatly improves the altitude labor efficiency, reduces the working cost, effectively ensures the effects of engineering quality and progress, and the like, but can cause continuous and continuous combustion of adjacent EPS boards when a large-area fire occurs due to the fact that a structure capable of coping with the large-area fire is not arranged.
