Six-in-one prefabricated concrete outer wall panel and production method thereof

Abstract

The invention provides a six-in-one prefabricated concrete outer wall panel and a production method thereof. The six-in-one prefabricated concrete outer wall panel comprises a hydrophobic self-cleaning coating layer, a flexible board, a crack-resistant mortar layer, a gridding cloth, a fireproof dry mixed mortar layer, a heat insulation board and a concrete board which are fixedly connected from outside to inside in sequence. Heat insulation nails are uniformly distributed on the heat insulation board, the end parts of one ends of the heat insulation nails are located in the heat insulation board, and the end parts of the other ends of the heat insulation nails are located in the concrete board. A plurality of strip-shaped through grooves with isosceles trapezoidal cross sections are formed in the lower surface of the heat insulation board, and the strip-shaped through grooves are arranged side by side and evenly distributed. Clamping blocks with isosceles trapezoidal cross sections are integrally arranged at the position, corresponding to the strip-shaped through grooves, on the upper surface of the concrete board, and the clamping blocks are embedded in the strip-shaped through grooves. The six-in-one prefabricated concrete outer wall panel adopts the closed design and has good fireproof performance; the strip-shaped through grooves and the heat insulation nails can increasethe bonding friction force between the heat insulation board and the concrete board after pouring concrete; and the six-in-one prefabricated concrete outer wall panel has the effects of load bearing,heat insulation, fireproof, waterproof, decoration and self cleaning.

Description

technical field [0001] The invention relates to building materials, in particular to a six-in-one assembled concrete exterior wall panel and a production method thereof. Background technique [0002] For a long time, cast-in-place or brick masonry structures have been widely used for exterior walls, and the usual method for exterior wall insulation is external insulation. The traditional external thermal insulation technology is to place the thermal insulation material on the outside of the external wall, which basically eliminates the thermal bridge and does not occupy the indoor use area, but has the disadvantages of difficult construction, easy cracking, easy falling off, and poor durability. Especially in recent years, the shedding of external wall insulation materials and external wall bricks often causes casualties, has great potential safety hazards, and has relatively bad social impact. [0003] At present, the country has begun to promote prefabricated buildings. A...

Problems solved by technology

However, most of the wall panel structures used in prefabricated buildings nowadays are in the form of "sandwich sandwich", that is, "200mm thick concrete structural wall + 50-60mm rock wool insulation layer + 60mm thick concrete protective layer". This structure can play a load-bearing role. , thermal insulation, and fire prevention functions, it also has a certain positive effect on preventing the insulation layer from falling off. destroy insulation

②Compared with the traditional "cast-in-place structural wall + external insulation" method, there is obviously an extra layer of 60mm thick concrete protection layer, which directly increases the cost

③ After the prefabricated exterior wall panels are installed, usually the decorative layer (waterproof layer) on the surface of the wall needs to be completed on site instead of factory integration, resulting in an increase in site workload and overall construction costs during the construction process
