Sound insulation composite insulation board for internal and external corners of building

Abstract

The invention relates to the technical field of buildings, and discloses a sound insulation composite insulation board for internal and external corners of a building. The sound insulation composite insulation board comprises corner embedded steel and composite boards, wherein the corner embedded steel is installed at the internal and external corners, and the composite boards are installed on both sides of the corner embedded steel; the corner embedded steel comprises two installation parts which are attached to the internal and external corners, the surfaces of the two installation parts are attached, or the edges of the two installation parts are in contact; and reserved installation cavities are formed in the outer sides of the installation parts at equal intervals, and first groove holes and second groove holes are respectively formed in both sides of the inner walls of the reserved installation cavities. A board body is improved, firstly, an adhesive layer is smeared in a protective layer, the protective layer sleeves two base plates, and then a vacuum pump is adopted to vacuumize the protective layer, so that the protective layer is stably adhered to the two base plates, and when the protective layer is locally damaged, air cannot enter the damaged part under the action of the adhesive layer, and moist air cannot directly enter the board, so that the service life of the board can be prolonged.

Description

technical field [0001] The invention relates to the field of building technology, in particular to a sound-insulating composite heat-insulation board used for the inner and outer corners of buildings. Background technique [0002] Sound insulation composite insulation board is a common building decoration material. In the process of interior decoration, the sound insulation composite insulation board is fixed by glue or nails. The fixing nails will penetrate the board, and water stains will appear in the gaps where it penetrates. Such corroded nailing will cause accelerated damage to the board, especially when installing at the yin and yang corners of the building, the place where the boards are attached will also suffer from moisture, and when the existing boards are damp. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a sound-insulating composite heat-insulation board ...

[0002] Sound insulation composite insulation board is a common building decoration material. In the process of interior decoration, the sound insulation composite insulation board is fixed by gluing or nailing. The fixing nails will penetrate the board, and water stains will appear in the gap where it penetrates. Such rusty nailing will accelerate the damage of the board, especially when installing at the yin and yang corners of the building, the place where the boards are attached will also suffer from moisture, and when the existing boards are damp,
