Fabricated outer wall based on lightweight outer wall enclosure plates

Abstract

The invention discloses a fabricated outer wall based on lightweight outer wall enclosure plates. The fabricated outer wall is formed by splicing a plurality of lightweight outer wall enclosure plates, and each lightweight outer wall enclosure plate comprises an outer acanthus, an inner acanthus and a heat preservation layer; a vertical grouting female groove is formed in each of the outer acanthus and the inner acanthus on the same vertical splicing surface; and the vertical grouting female grooves between the adjacent lightweight outer wall enclosure plates form grouting channels penetrating up and down. The grouting channels are densely filled with bonding slurry, the bonding slurry bonds two adjacent lightweight outer wall enclosure plates, and the upper ends and the lower ends of the lightweight outer wall enclosure plates are connected to a main building body structure through connecting pieces. The fabricated outer wall is simple in structure, high in construction efficiency, strong in wind pressure resistance and good in fire resistance, and has a heat preservation function. Therefore, the problem that cracks are likely to be generated at the abutted seam of existing inner and outer wall enclosure plates is solved, and the flatness is high; and in addition, construction of the decorative surface layer in the later period is facilitated, and the phenomena of water leakage, sound insulation and cold and hot bridges of the decorative surface layer due to insufficient flatness of the inner wall and cracking of abutted seams are avoided.

Description

technical field [0001] The invention belongs to the technical field of non-loading exterior wall enclosures, in particular to an assembled exterior wall based on lightweight exterior wall enclosures. Background technique [0002] At present, there are several common building types in my country: brick-concrete structure, cast-in-place concrete shear wall structure, cast-in-place concrete frame structure, steel structure, etc. Among them, brick-concrete structure is the most widely used and has a long history, but due to protection The country has legislated to phase out and prohibit the use of clay bricks for the environment and the need to save farmland, so the brick-concrete structure is about to be phased out, and other construction methods are also complicated because of the technology, so the construction speed is slow, the construction period is long, and the level of building industrialization is low. .

Problems solved by technology

[0002] At present, there are several common building types in my country: brick-concrete structure, cast-in-place concrete shear wall structure, cast-in-place concrete frame structure, steel structure, etc. Among them, brick-concrete structure is the most widely used and has a long history, but due to protection The country has legislated to phase out and prohibit the use of clay bricks for the environment and the need to save farmland, so the brick-concrete structure is about to be phased out, and other construction methods are also complicated because of the technology, so the construction speed is slow, the construction period is long, and the level of building industrialization is low.

Especially in the case of a frame structure such as a concrete frame or a steel structure, a large construction period is wasted on the construction of the exterior wall, because the construction of the exterior wall needs to build the wall with concrete bricks first, and then use concrete or concrete on the outer surface of the exterior wall. Cement or tiles are reinforced to play the role of waterproof, heat preservation and cold protection. This operation method is very troublesome, labor-intensive and time-consuming, and the heat preservation effect is not ideal. In recent years, many architectural research institutions or construction units have adopted new types of prefabricated walls that can be industrialized. The use of solid building materials, such as various prefabricated external wall hanging panels, speeds up the construction to a certain extent, but the structure is relatively complex, the construction efficiency is low, and the thermal insulation effect is relatively poor

[0003] However, the construction of these improved assembled wall building materials is still relatively complicated due to structural and material reasons, the market conversion rate is low, and the external walls still need to be operated using traditional methods. High, strong wind pressure resistance, good fire resistance, and self-insulated prefabricated exterior walls based on lightweight exterior wall enclosures
