Pure light steel joist ceiling

Abstract

The invention discloses a pure light steel joist ceiling, which comprises a terrace base layer, gypsum boards and gypsum lines (4), and a main joist (2). The terrace base layer comprises L-shaped side joists (1) and auxiliary joists (3). The auxiliary joists (3) form skeleton supports of the terrace base layer. The internal corners and / or external corners of the terrace base layer are connected through full-length L-shaped side joists (1). The face layers of the terrace base layer are covered by the gypsum boards and gypsum lines (4) to form an integral ceiling. The auxiliary joists (3) are connected with the main joist (2). The main joist (2) is fixed on the upper interior surface of a room through lead screws (5). The L-shaped side joists (1) and the auxiliary joist (3) are fixedly connected through rivets. The pure light steel joist ceiling has the advantages that the fire protection requirements on the ceiling can be satisfied, the problems of high formaldehyde content and the like caused by using a wood base layer for the ceiling are reduced, and a series of common quality problems such as cracking, deformation, corrosion and damages by worms caused by using the wood base layer can be solved.

Description

technical field [0001] The invention relates to the light steel keel ceiling technology of modern building decoration engineering, in particular to a pure light steel keel ceiling. Background technique [0002] At present, domestic and foreign light steel keels and gypsum board ceilings have modeling parts, and the base layer is made of wood base (wood board, plywood, etc.). With the continuous development of the decoration industry, the use of wood base in the ceiling has gradually failed to meet the industry Due to the requirements of development, the shape of the suspended ceiling made of wood base is prone to a series of common quality problems such as cracking, deformation, corrosion, and insects; moreover, the wood base will also bring problems such as formaldehyde content and fire prevention difficulties. Contents of the invention [0003] The purpose of the present invention is to provide a pure light steel keel ceiling, which can ensure the fire prevention require...
