Fabricated type prefabricated light concrete outer wall enclosure plate

Abstract

The invention discloses a fabricated type prefabricated light concrete outer wall enclosure plate. The outer wall enclosure plate is characterized by comprising an outer acanthus and an inner acanthus which are made of cement-based building materials, and a heat preservation layer bonded between the outer acanthus and the inner acanthus; and the outer acanthus and the inner acanthus on the same vertical splicing face are each provided with a vertical grouting female groove. The outer wall enclosure plate is simple in structure, high in construction efficiency, strong in wind pressure resistance and good in fire resistance, has a heat preservation function and solves the problem that cracks are likely to be generated at the abutted seam of existing inner and outer wall enclosure plates. Therefore, an outer wall installed on the outer wall enclosure plate does not crack and is high in flatness; double-plate overlapping construction is not needed, the situation that gridding cloth and anti-crack mortar are laid on the surface of the whole wall body for plastering and leveling is not needed, and no cracking phenomenon exists at the abutted seam; 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-load-bearing exterior wall enclosures, in particular to an assembled prefabricated light concrete exterior wall enclosure. 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 prefabricated prefabricated light concrete exterior wall enclosures with insulation
