ASSEMBLED-TYPE LIGHT STEEL BEAM PLASTERBOARD IRREGULARLY-SHAPED DROPPED CEILING SYSTEM

摘要

An assembled-type light steel beam plasterboard irregularly-shaped dropped ceiling system. An irregularly-shaped dropped ceiling basic structure thereof comprises a top part light steel beam frame (1), a bottom part light steel beam frame (2), an intermediate decorative façade (3), and an irregularly-shaped decorative element. A piece of plasterboard (4) is covered on the surface of the bottom part light steel beam frame (2). The decorative façade (3) is constituted by a fireproof panel. The top part of the decorative façade (3) and the top part light steel beam frame (1) are connected therebetween and the bottom part light steel beam frame (2) and the decorative façade (3) are connected therebetween both via prefabricated connecting elements. A planar dropped ceiling basic structure and the irregularly-shaped dropped ceiling basic structure are connected therebetween via a borderline beam (5). A prefabricated engaging element (6) is fitted at the bottom of the irregularly-shaped dropped ceiling basic structure. One end of the prefabricated engaging element (6) is connected to the irregularly-shaped decorative element, while the other end is provided with a transverse recessed part (61) for insertion by an end part of the plasterboard (4), where the overlapped portions of both are penetratively connected. The configuration of the borderline beam (5) allows the irregularly-shaped dropped ceiling basic structure and the planar dropped ceiling basic structure to be constructed separately. The prefabricated engaging element (6) and the plasterboard (4) implement a state of connection of stacked layers and are not prone to cracking after being penetratively connected.
