Background
Since the last 90 s, our country has begun to popularize and apply the external thermal insulation system of thin-plastered exterior wall, has been applied to the earlier multi-story buildings for more than 20 years, and has been comprehensively popularized and applied to the high-rise buildings through years of application and practice. The phenomena of material stealing and material reduction and rough manufacture and abuse are serious along with the reasons of large engineering construction amount, over-high construction speed, low price and bid winning and the like. In particular, in recent years, the problems of exposed external thermal insulation systems (including surface cracking, water seepage, cracking and peeling of protective layers, peeling of thermal insulation layers, and the like) are increasing, and complaints caused by the problems, personal injuries, vehicle damage, and the like are rare. The technical code of the external thermal insulation engineering of the external wall (JGJ144-2004), article 3.0.10, the service life of the external thermal insulation engineering of the external wall should not be less than 25 years under the conditions of normal use and normal maintenance. Some buildings have reached the end of their useful life. The main mode of repair at the present stage is repair and simple and rough removal, and based on the background, the research of the repair technology of the external thermal insulation system of the existing building external wall is urgent.
The problems of cracking, hollowing and falling of a protective layer, water leakage of an outer wall, falling of a heat insulation layer and the like of the thin-plastered outer wall external heat insulation system occur due to factors such as quality defects, temperature fields, internal stress and the like. The existing thin-plastering external thermal insulation system for the external wall is connected in a bonding and anchor bolt anchoring mode, the thermal insulation layer bears drawing force and shearing force, the influence of negative wind pressure is large, the thermal insulation layer is directly connected with a plastering mortar layer, the deformation rate difference of two materials influenced by expansion and contraction is large, and a plurality of problems are caused.
Disclosure of Invention
The utility model discloses to the technical problem who exists among the prior art, provide a whole repair structure of outer heat preservation system of thin outer wall that plasters, keep warm outward to the outer wall on the basis that does not demolish former heat preservation and repair, satisfy operation requirement, friendly to the environment, little to the community influence, synthesize economic cost low.
The utility model adopts the technical proposal that: the utility model provides a whole structure of repairing of outer thermal insulation system of thin plastering, includes flexible light thick liquids layer, metal mesh, crab-bolt, anti mortar layer and alkali-resisting screen cloth of cracking, is provided with the heat preservation outside the basic wall body, flexible light thick liquids layer is located the heat preservation outside, is provided with the metal mesh in it, be provided with the diffusion dish on the crab-bolt, the diffusion dish passes through the fastener and is connected with the metal mesh, the crab-bolt runs through the heat preservation, and its front end is located the basic wall body, flexible light thick liquids layer is provided with anti mortar layer outward, set up alkali-resisting screen cloth in the anti mortar layer of cracking.
Preferably, an expansion pipe is arranged in the foundation wall, and the front end of the anchor bolt is positioned in the expansion pipe.
Preferably, the metal mesh is a hot-dip galvanized mesh.
Preferably, the metal mesh is located at the middle position of the flexible lightweight pulp layer.
Preferably, the thickness of the flexible light-weight slurry layer is 20-30 mm.
Preferably, the thickness of the anti-crack mortar layer is 3-5 mm.
The working principle is as follows: the technology adopts the technical scheme that a plastering protective layer is directly connected with a basic wall body through anchor bolts and is formed by a hot galvanizing welded mesh and a flexible light slurry layer, so that a complete new structural system is formed, and the load of an original heat-insulating layer is not increased. The foundation wall, the original heat-insulating layer and the plastering protective layer form a sandwich structure measure, and the original heat-insulating layer is effectively protected. And the plastering protective layer adopts flexible light slurry as a structural transition layer and adopts a hot galvanizing welded net as a reinforcing structure, so that the unification between the anti-cracking performance and the requirement of the decorative surface on the strength of the base layer can be effectively considered, and the stability, the safety and the durability of a heat insulation system are met. The hot galvanizing welded mesh has high rigidity and good elasticity, and can absorb the internal stress of the heat preservation layer through the structure transition layer, so that the whole structure system is more stable.
Compared with the prior art, the utility model discloses the beneficial effect who has is: the utility model discloses keep warm outward to the outer wall on the basis that does not demolish former heat preservation and restore, satisfy operation requirement, friendly to the environment, little to the community influence, synthesize economic cost low.
