Description

Technical Field

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

[0002] Lightweight steel keel is a kind of building decoration material made of lightweight steel, usually made of galvanized steel plate or organic coating steel plate. Its cross-section is generally C-shaped or U-shaped, with excellent corrosion resistance, fire resistance, high strength, light weight, and convenient construction.

[0003] Generally, light steel keels are formed by bending and punching steel plates several times or are used directly. There are some shortcomings in the installation and use of light steel keels. On the one hand, light steel keels need to be fixed with multiple screws, which are easy to deviate during the punching process, affecting the positioning and installation effect of the light steel keel. On the other hand, the edge strength of light steel keels is low, and they are prone to bending during installation and use. Utility Model Content

[0004] The utility model aims to solve the problems that during the installation and use of the above-mentioned light steel keel, the screws are easily deviated during the punching process, which affects the positioning and installation effect of the light steel keel, and the edge strength of the light steel keel is low, and it is easy to bend during the installation and use.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is: a new type of light steel keel, including a keel body bent into a trapezoidal shape by a plate, the trapezoidal shape is outwardly bent, which is conducive to load-bearing, and the keel body includes a top plate, side plates are provided on both sides of the top plate, and a bottom plate parallel to the top plate is provided at the lower end of the side plate, a plurality of pits are evenly arrayed on the top plate, and a plurality of square holes are equidistantly arrayed along a straight line on the bottom plate.

[0006] As an improvement, the sides of the bottom plate are each provided with a first folded edge, which is folded inwardly and downwardly and is located outside the square hole.

[0007] As an improvement, a second folded edge is provided on one side below the square hole.

[0008] As an improvement, the pits are arranged to protrude from the top plate toward the inner side of the top plate.

[0009] The advantages of the utility model are: on the one hand, it is convenient for positioning and installation, a plurality of square holes are arranged in a straight line equidistant array on the bottom plate, and holes are punched on both sides to facilitate the passage of screws, and multiple groups of pitting are arranged to facilitate the connection between the top plate and the wall panel, and the screws can be quickly positioned to the center point during the installation and fixing operation, and the screws are not easy to slip during the installation process, thereby improving the convenience of installation of the keel body and the accuracy of the installation position; on the other hand, the first folded edge forms a double layer of material thickness at the lower edge of the bottom plate, thereby increasing the strength of the product and making the edge of the bottom plate smoother, and the second folded edge increases the friction of the contact surface of the bottom plate, thereby preventing it from falling off after being fixed, thereby improving the stability of the installation of the keel body.

[0014] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0015] Combined with Figure 1 , Figure 2 , Figure 3 A new type of light steel keel includes a keel body 1 bent into a trapezoidal shape by a plate material. The trapezoidal shape is outwardly bent, which is conducive to load-bearing. The keel body 1 includes a top plate 2, side plates 3 are arranged on both sides of the top plate 2, and a bottom plate 4 parallel to the top plate 2 is arranged at the lower end of the side plate 3. A plurality of pitting points 5 are evenly arranged on the top plate 2, and a plurality of square holes 6 are equidistantly arranged along a straight line on the bottom plate 4, and holes are punched on both sides to facilitate the passage of screws.

[0016] The sides of the bottom plate 4 are all provided with a first folded edge 7, which is folded inward and downward and located outside the square hole 6. The first folded edge 7 forms a double layer of material thickness at the lower edge of the bottom plate 4, thereby increasing the product strength and making the edge of the bottom plate 4 smoother.

[0017] A second folded edge 8 is provided on one side below the square hole 6 , and the second folded edge 8 increases the friction force of the contact surface of the bottom plate 4 , so that the keel body 1 is not easy to fall off after being fixed, thereby improving the installation stability of the keel body 1 .

[0018] As an improvement, the pits 5 are protruding from the upper surface of the top plate 2 toward the inner side of the top plate 2. The multiple groups of pits 5 are convenient for connecting the top plate 2 and the wall panel. The screws can be quickly positioned at the center point during the installation and fixing operation. The screws are not easy to slip during the installation process, thereby improving the convenience of installation of the keel body 1 and the accuracy of the installation position.

[0019] During the specific implementation of the utility model, during preparation, a light steel plate is bent into a trapezoidal keel body, and the two sides are bent inside the box to form a first folded edge. A square hole is opened on the bottom plate of the keel body, and the remaining material of the opened square hole is bent toward the bottom to form a second folded edge. Pockmarks are evenly formed on the top plate, and the pointed ends of the pockmarks protrude toward the inner side of the keel body.

[0020] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
