Connecting-fixing device for cascaded shape of ceiling, ceiling system and construction method

Abstract

The invention provides a connecting-fixing device for the cascaded shape of a ceiling, a ceiling system and a construction method, and relates to the field of ceiling construction. The connecting-fixing device for the cascaded shape of the ceiling comprises an auxiliary keel connector and further comprises a hanging rod connector (1.6), wherein the auxiliary keel connector comprises a U-shaped main body (1.1) and connecting plates; the U-shaped main body and the connecting plates are of an integrated structure; the connecting plates can be bent along the U-shaped main body; the entire cross section of the U-shaped main body is U-shaped; the upper part of the inner surface of a vertical limb of the U-shaped main body protrudes inwardly so as to form a rectangular bump; the outer side of thelower surface of the rectangular bump protrudes downwardly so as to form a convex head; a rear-end plate and two side plates of the hanging rod connector are inserted into an inserting groove of theU-shaped main body; and a baseplate is supported on one end surface of the U-shaped main body so as to form a joint fixing component. By the adoption of the connecting-fixing device provided by the invention, the problem that the ceiling keel system fault tolerant rate of a conventional ceiling of the cascaded shape is relatively small and the problem that through a conventional connecting-fixingmethod, not only is the original supporting capacity of an auxiliary keel weakened, but also the time and the effort are wasted as well as the waste of materials is caused can be solved.

Description

technical field [0001] The invention relates to the field of suspended ceiling construction, in particular to a connection and fixing device, a suspended ceiling system and a construction method for cascading molding of a suspended ceiling. Background technique [0002] At present, the fault tolerance rate of the existing cascaded ceiling to the ceiling keel system is relatively small. When the size of the high-level sub-keel used to fix the laminated cladding panels in the joist system is not measured in advance before installation, the cantilevered end ends overlap vertically with the end of the bottom-level sub-keel protruding from the wall , so before fixing the vertical cladding panels, it is necessary to cut off the overhanging part of the first row of auxiliary keels with high elevation, so that the ends of the upper and lower rows of auxiliary keels correspond in the vertical direction, and use steam nails to cut the auxiliary keels with the other The side keels or ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a connection and fixing device, a ceiling system and a construction method for the cascading shape of the suspended ceiling. It weakens the original supporting capacity of the auxiliary keel, and is time-consuming and labor-intensive. It is very easy to waste materials due to improper operation. It solves the problem of poor fire protection and durability of the existing wooden squares as accessories for stable cladding panels.
