Suspended-ceiling assembled steel frame transfer story

Abstract

The invention relates to a suspended-ceiling assembled steel frame transfer story which comprises transfer story vertical rods, transfer story transverse rods, lead screws, multiple first hanging parts, second hanging parts, clamping parts, main keels, auxiliary keels and fasteners. The transfer story vertical rods and the transfer story transverse rods are connected, the first hanging parts are connected with the transfer story transverse rods, the multiple hanging parts are arranged at intervals, the lead screws are connected with the first hanging parts through the fastening parts, the second hanging parts are connected with the lead screws, the main keels are installed on the second hanging parts, the auxiliary keels are connected with the main keels through the clamping parts, and theauxiliary keels are located below the main keels. The suspended-ceiling assembled steel frame transfer story utilizes a physical structure form to install and fix a keel system on a steel angle transfer story. Due to the fact that a penetrating-plugging hook mode is adopted for the first hanging parts and the second hanging parts, the separation distances of the hanging parts can be optionally adjusted on steel angles, construction is flexible, quick and convenient, and meanwhile a certain space exists in each hanging part, so that effective adjustment of the flatness of a suspended ceiling can be achieved by utilizing fastening nuts.

Description

technical field [0001] The invention relates to the technical field of architectural decoration, in particular to a ceiling-assembled steel frame transfer layer. Background technique [0002] The traditional steel frame transfer layer process steps are mainly divided into: measuring and setting out, drilling and embedding expansion bolts, installing angle steel suspenders, welding the transfer layer steel frame, and painting antirust paint. However, the angle steel of the transfer layer needs to be perforated in advance, which affects the construction efficiency. At the same time, the angle steel is damaged to a certain extent after the hole processing, which affects the strength of the transfer layer to a certain extent. In some projects, the hanging bars are directly welded to the side of the angle steel for the sake of convenience, which has potential quality problems. At the same time, it is inconvenient to issue a fire certificate during construction. Contents of the...
