Description

Sound insulation glass magnesium board Technical Field The utility model relates to the technical field of building materials, in particular to a sound insulation glass magnesium board. Background The glass magnesium board is also called as magnesium oxide board, is a light building material, and is made up by using cementing material made up by using magnesium oxide, magnesium chloride and water as main body and adding proper quantity of reinforcing material, such as glass fibre mesh cloth, etc.. The patent with the application number 202420357254.8 discloses a sound insulation glass magnesium board, which comprises a hollow glass magnesium board main body, wherein a plurality of cavities are formed in the hollow glass magnesium board main body, two ends of each cavity penetrate through the front end face and the rear end face of the hollow glass magnesium board main body respectively, a plurality of hard sound insulation core materials are respectively penetrated in the cavities, accommodating grooves are respectively formed in the front end face and the rear end face of the hollow glass magnesium board main body, two sealing plates are respectively embedded in the accommodating grooves and fixedly connected in the accommodating grooves, a plurality of positioning grooves corresponding to the hard sound insulation core materials one by one are respectively formed in the inner side faces of the two sealing plates, and two ends of the hard sound insulation core materials are respectively inserted into the corresponding positioning grooves. The sound-insulating glass magnesium board has reasonable structure, and the sound-insulating effect of the glass magnesium board is enhanced by arranging the hard sound-insulating core material in the inner cavity of the hollow glass magnesium board main body, but the hard sound-insulating core materials are arranged at intervals in the length direction of the hollow glass magnesium board main body, so that the sound-insulating effect of the part between two adjacent hard sound-insulating core materials is poor.
