Description
Technical Field
The invention relates to the building industry, in particular to a precast concrete integrated heat-insulating wall component and a construction method thereof.
Background
With the rapid development of economy, various industries are continuously developing new products, aiming at saving energy, reducing pollution and improving production efficiency, continuously breaking through the traditional production mode, and building industrialization advancing to a standardized system is developed at a high speed in recent years. The building industrialization realizes the universalization of building components and the assembly and mechanization of field construction by applying a modern management mode and through standardized building design and modular and industrialized part production, and is beneficial to promoting the transformation and upgrading of the building industry in China. The sandwich heat-insulation assembled wall precast concrete member and the inverted-beating integrated heat-insulation wall precast concrete member adopting the heat-insulation and structure integration technology are produced under the dual backgrounds of building industrialization and energy conservation and consumption reduction.
The concrete structure of the sandwich heat-insulation assembly type wall prefabricated part in the prior art is shown in figure 1, a wall layer 1 and a floor slab 2 are directly filled with mortar 3, sandwich heat-insulation boards 7 are connected to the outer side of the wall layer 1, and a PE foam rod 5 and silica gel 6 are filled between every two adjacent sandwich heat-insulation boards 7 through mortar 4. The concrete structure of the reverse beating integrated heat-preservation assembled wall prefabricated part in the prior art is shown in fig. 2, a wall body layer 1 and a floor slab 2 are directly filled with a slurry 3, heat-preservation plates 8 are connected to the outer side of the wall body layer 1, and a PE foam rod 5 and silica gel 6 are filled and filled between every two adjacent heat-preservation plates 8 through the slurry 4.
No matter the prefabricated components of the sandwich heat-preservation assembled wall body or the reversely-beating integrated heat-preservation assembled wall body are connected in a sleeve grouting mode, horizontal grouting seams always exist inevitably. The existence of the horizontal grouting seam can affect the actual heat insulation effect due to the cold bridge problem. 1, when a sandwich heat-preservation assembled wall prefabricated part is adopted, the existing method is waterproof, a concrete bottom edge sealing structure is often adopted, the cold bridge area is enlarged, the cold bridge effect is intensified, and the heat-preservation and heat-insulation efficiency of a building is influenced; 2, for eliminating the cold bridge influence as far as possible, adopt the bottom not banding structure, horizontal grout seam runs through the heat preservation this moment, causes grout seam department heat preservation upper and lower discontinuity, also aggravates cold bridge harm, even when adopting the anti-integrated heat preservation assembled wall prefabricated component of beating, also has the same problem. In addition: the depth of a horizontal grouting joint of a sandwich heat-insulation assembly wall prefabricated part generally reaches more than 100mm, the depth of the horizontal grouting joint of a reverse-beating integrated heat-insulation assembly wall prefabricated part is also equal to the thickness of a heat-insulation plate and often reaches more than 55mm, so that great operational inconvenience exists during the construction of seat slurry, the seat slurry is extruded at the lower end of the heat-insulation plate (when the edge is not sealed), the upper heat-insulation plate and the lower heat-insulation plate are not completely continuous or are mostly separated, and a cold bridge is formed; if during banding structure, should pack more cement base thick liquids cold bridge effect aggravation between the upper and lower heated board that originally and discontinuous. In the subsequent treatment of the grouting seam, the conventional method at present adopts that silica gel is also applied after a PE foam rod is filled. The operation procedures are multiple, the requirement on the construction quality is high, and if the operation is not standard, the hidden danger of later-stage water leakage is buried; the horizontal grouting joint still often destroys the visual effect required by the original design of the outer facade of the building, and in order to achieve the original design purpose, the horizontal grouting joint needs to be shielded, and the horizontal grouting joint is usually covered by an anti-cracking layer which is formed by firstly coating an interface agent, then externally adding anti-cracking mortar and grid cloth. However, as the anti-crack mortar is covered on the elastic silica gel material, local concave and convex conditions exist due to expansion with heat and contraction with cold of the silica gel, even the surface anti-crack mortar cracks, and not only water seepage is caused, but also poor visual effect is brought.
