Vertical light steel keel

Abstract

The invention discloses a vertical light steel keel which is applied to the field of building decoration and paving. Strip steel serves as a raw material to be continuously cold-rolled and formed through a machine to form a plurality of continuous staggered forward U-shaped grooves and inverted U-shaped grooves; the bottom faces of the multiple forward U-shaped grooves and the bottom faces of themultiple inverted U-shaped grooves constitute connecting fixing faces with the two opposite sides correspondingly for connecting and fixing other keels or connecting pieces on the double sides; the space of the forward U-shaped grooves and the space of the inverted U-shaped grooves are used for placing the tails of fasteners which are connected and fixed to be used; and when the other keels and connecting pieces are connected on the double sides in the same local position, double-side graded connection and fixing can be achieved, and the flatness of the double-side connecting fixing faces is not destroyed. Through the structural characteristics of the U-shaped grooves, the keel is also naturally provided with a plurality of reinforcing ribs, and thus the stress strength of the keel is improved; and compared with using of a C-shaped cladding keel in the prior art, the advantages of higher efficiency, lower labor intensity and higher stress strength are achieved; and compared with usingof a square pipe in the prior art, the advantages of less consumable use, lower production cost, higher stress strength, more convenient and quicker use and the like are achieved.

Description

technical field [0001] The invention relates to the field of architectural decoration and pavement, in particular to a vertical light steel keel. Background technique [0002] In the light steel keel gypsum board ceiling, the vertical light steel keel currently used is mainly C-shaped cladding keel and square tube when making the ceiling shape. When it is necessary to connect and fix other keels and connectors on both sides at the same local position, such as using a C-shaped cladding keel as a vertical keel, its structural characteristics determine that it cannot be connected and fixed on both sides in stages, and can only be connected and fixed by stacking the three Therefore, it will cause disadvantages such as low construction efficiency and high labor intensity. If a square tube is used as the vertical keel, although it can be connected and fixed on both sides in stages, it will cause disadvantages such as high cost of use and poor effect of fixed connection.
