Large-area mineral fiber board ceiling structure

Abstract

The invention discloses a large-area mineral fiber board ceiling structure. The structure comprises a hanging steel bar, wherein a main keel is hung on the hanging steel bar, and the main keel is provided with a drywall provided with mineral fiber boards; the mineral fiber boards and the drywall are fixedly connected with the main keel through screws, and the contacting corners of adjacent mineral fiber boards are fixedly connected with each other through compression joint devices; each compression joint device comprises a transect and a longitudinal section, each transect is arranged perpendicular to each longitudinal section, and a cross is formed by each transect and each longitudinal section; openings are arranged on the lower portions of each transect and each longitudinal section, and a clamping strip is arranged on the internal wall of each opening; a connecting pressure plate is arranged between each transect and each longitudinal section. The mineral fiber board ceiling structure has the advantages of being convenient to install, simple in structure and good in acoustic absorption and insulation; by adopting the compression joint device for connection and fixation, the large-area mineral fiber board ceiling structure is suitable for installation of large-area mineral fiber board ceilings, and not likely to deform.

Description

technical field [0001] The invention relates to a suspended ceiling structure, in particular to a large-area mineral wool board suspended ceiling structure. Background technique [0002] Light steel keel plasterboard is a ceiling material widely used in various indoor spaces. Since certain spaces such as conferences, schools, etc. have certain sound-absorbing requirements, it is difficult for plasterboard to meet this requirement, so in Mineral wool boards are used in daily buildings. Mineral wool boards have the characteristics of sound absorption, waterproof, heat preservation, heat insulation, light weight, elegant appearance, and simple construction. They are widely used in rooms with sound absorption requirements, but the existing mineral wool boards The size of the ceiling is relatively small, generally 80mm*80mm. If a large area of ​​mineral wool board is used as the ceiling, the ordinary main keel can no longer meet the requirements of fixed connection, and it is eas...
