Description

Technical Field

[0001] The utility model relates to the technical field of light steel keels, in particular to a bendable light steel keel. Background Art

[0002] Light steel keel is a kind of lightweight metal framework material widely used in modern building decoration, mainly used to support and fix the ceiling, partition wall and various decorative plates inside the building. It is formed by rolling cold-rolled thin steel plates and has good mechanical strength and corrosion resistance. The light steel keel system includes main keels, secondary keels (also known as cross braces or vertical braces), connectors and fasteners, etc. Through precise dimensions and designs, it can achieve rapid installation and flexible adjustment to meet the needs of different spaces and designs. In addition, the light steel keel also has the advantages of light weight, convenient construction, strong bearing capacity, good fire resistance, etc., and is suitable for various building environments, including residential buildings, commercial spaces, offices, etc. During installation, the light steel keel system needs to be strictly constructed in accordance with the construction specifications to ensure the stability and safety of the structure. At the same time, the surface treatment process of the light steel keel is also very important. Common ones include galvanizing, spraying, etc. These treatments can further improve its durability and aesthetics.

[0003] When the light steel keel is used as a ceiling, there are corners on the ceiling. There are two ways to set the light steel keel at the corners. One is to directly cut the light steel keel and then connect a light steel keel perpendicular to it on one side of the light steel keel. The other is to bend the light steel keel so that it can adapt to the corners of the ceiling.

[0004] However, at present, during the actual construction of houses by developers, there is no way to make the ceilings of houses all present a state of 90° corners. Even some house patterns are not rectangular but triangular or even diamond-shaped. In this way, there is only one way to bend the light steel keel to adapt to the house pattern of the ceiling. But generally, this kind of light steel keel needs to be measured and then the production manufacturer re-presses and bends the light steel keel to ensure that the angle of the light steel keel is bent within the required range and can also be bent at a fixed point. However, for the construction team, this will greatly delay the construction period and extend the construction cycle.

[0005] Therefore, a bendable light steel keel is proposed to solve or alleviate the above problems. Content of the Utility Model

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] A bendable light steel keel, as Figure 1 and 2 shown, includes a keel frame 1. The cross-section of the keel frame 1 is C-shaped, and a plurality of deformation grooves 2 are arranged at intervals on the keel frame 1 with a side opening.
